Institutional and economic determinants of Indian OFDI

Abstract The study explores the primary determinants of Indian OFDI in 26 developed and 81 developing countries by integrating a nuanced perspective of institutional distance with conventional location factors (2008–2018). Our findings indicate that asset augmentation and market-seeking motives are the primary OFDI drivers in developed and developing regions, respectively. Overall, the institutional environment demonstrates a positive association between Indian OFDI and the robust governance quality of the host country (excluding RS investments in developing region). However, only robust regulatory quality (RQ) & control of corruption (CC) are the primary IQ determinants significantly attracting OFDI in developed nations. Surprisingly, none of the WGI significantly drives OFDI in developing countries. However, the interaction effect reveals that only market-seeking investors from India are drawn to highly regulated (RQ), rule-based (RL) developing nations. The estimated FDI factors differ significantly depending on the destination, but RQ largely remains the crucial determinant across regions.

The relationship between institutions and OFDI has recently received much attention from researchers and policymakers. Several researchers have examined the OFDI determinants linked to host and home countries' institutional characteristics and factors such as high institutional quality (IQ), 1 low labor costs, ease of doing business and other macroeconomic stability-related aspects (Buckley et al., 2016;Jung, 2020;Ren et al., 2022;Zidi & Ali, 2016). Nevertheless, most existing research is focused on China's OFDI, primarily driven by state-created advantages such as preferential access to capital, expedited approvals, technological support, tax advantages, and social networks in foreign markets (Yin et al., 2021;Zhu et al., 2022). Such preferential treatment enables Chinese OFDI to mitigate the disadvantages of "home country embeddedness" and institutional distances (ID), i.e., the difference between home-host institutional environment (IE) (Angulo-Ruiz et al., 2019). It further aids funding presumably least valuable technological and brand-seeking forays, notably in developed nations, which would otherwise jeopardize the investing firm's long-term survival (Buckley, 2018). This confines the application of findings to other Asian developing countries where the state advantages are not ubiquitous and the private sector primarily supports OFDI. India aims to promote OFDI through relaxations in overseas investment norms, significantly strengthened by the Modi government since 2014 through policy interventions and institutional transformations. North's (1990) Institutional framework highlighting the significance of institutions and its interaction within the economy provides a basis for investigating the institution-FDI relationship. According to Dunning's (1977) eclectic paradigm, economic variables such as GDP, population, labor and transportation costs, institutions, and governance quality significantly influence FDI. Literature suggests that institutional variables predict the destination choice of FDI more effectively than economic factors (Kang & Jiang, 2012;Altomonte, 2000). While conceptual studies exist exploring the effects of Indian OFDI on internationalization and global economic integration (Amendolagine et al., 2022;Chiappini & Viaud, 2021), empirical knowledge on how home-host ID affects OFDI motives is limited. India's evolving formal institutional architecture, with the ambition to connect Indian firms with global markets under the Modi regime, presents a unique setting for reexamining Indian MNEs' OFDI motivations and the influence of ID on OFDI.
Institutional voids distinctively characterize IE in a developing economy on various governance fronts (Wang & Lahiri, 2022). This compels EMNEs to indulge in "institutional arbitrage" through "institutional escapism" and "institutional exploitation" to manage the isomorphic burden of homehost ID (Buitrago et al., 2020;Luo & Tung, 2018;Nayyar et al., 2021). Studies report mixed evidence of the OFDI-ID relationship. Few studies demonstrate that EMNEs respond positively to hostcountry institutional weaknesses (Asaad & Marane, 2020;Park, 2018;Wei & Nguyen, 2017), whereas others report them preferring robust IE to avoid home institutional constraints (Rienda et al., 2019;Witt & Lewin, 2007). Such disparities demonstrate that IB needs to understand EMNEs' OFDI across institutional settings completely, and further, the Chinese context could not be generalized due to the limitations mentioned earlier.
The study develops a multi-theoretic framework combining an institution-based view (IBV) with Dunning's eclectic framework and contributes to theory and practice in multiple ways. First, the study examines primary OFDI determinants, both institutional (host-home ID) and economic (FDI motives), from the perspective of the developing Indian economy. The directionality rationale of ID is an assessment of how well the host country's institutions work for foreign investors compared to the home country's institutions (Zaheer et al., 2012). When a firm invests in institutionally better-performing (worse) country compared to home, its ID rises (decreases). Second, IE measured by a given set of institutional indicators varies across regions (Ahuja & Yayavaram, 2011); hence, categorizing nations into distinct groups (developing and developed) offers a more effective and integrated view of the institution-based overseas investment strategy. Third, assuming ID's asymmetric impact on OFDI motives (Zaheer et al., 2012), the study explores how FDI motivations interact with ID to promote investment. Fourth, instead of an aggregate institutional index (Fon & Alon, 2022;Nayyar et al., 2021), the study employs six governance aspects of Worldwide Governance Indicators (WGI) (see methodology section) to capture their impacts separately. The authors believe that findings based on distinct institutional dimensions may enable policymakers to investigate more specific guidelines to attract or boost Indian OFDI. Simultaneously, it will guide Indian firms in aligning their internationalization motivations with the IE prevalent in the host country.
A contemporary understanding of the motivational and institutional forces influencing Indian OFDI in developing and developed regions will be gained by employing a Poisson-Pseudo Maximum Likelihood (PPML) estimation (Silva & Tenreyro, 2006) with a panel data set. The estimation is based on RBI data on Indian OFDI in 107 host countries, 26 developed and 81 developing, from 2008 to 2018. Findings demonstrate that asset-augmenting efficiency-seeking (ES) motives in developed regions and market-seeking (MS) motives in developing regions are the primary Indian OFDI motivations. In a developing host country, robust IE has an insignificant positive effect on OFDI. However, the interaction effect indicates that the developing economy's robust rule of law (RL) and regulatory quality (RQ) have a significant and positive influence on MS OFDI (institutional escapism). In contrast, weak PS and VA influence RS OFDI (institutional exploitation) in developing regions. On the contrary, robust RQ and corruption control (CC) are the primary institutional factors attracting OFDI ((institutional escapism) in the developed region.
The remaining paper is organized as follows. The second section reviews the theoretical framework of FDI, the third section explains the empirical methodology, the fourth section discusses empirical findings, and the last section concludes.

Theoretical framework
Several theoretical perspectives, such as neoclassical trade concepts (H-O Model), product life cycle model (Vernon, 1966), market imperfection theory (Hymer, 1976;Kindleberger, 1969), eclectic paradigm (Dunning, 1977), and knowledge-capital model (Markusen, 2002) have been widely used to address why firms invest overseas. Dunning's eclectic paradigm or the ownershiplocational-internalization (OLI) framework, incorporating Hymer's (1976) monopolistic advantages or asset-exploitation approach and Buckley and Casson's (1976) internalization theory, has been the most comprehensive theoretical model explaining MNEs OFDI motives. The framework assumes that an MNEs investment decision is characterized by its ability to capitalize on firmspecific ownership and locational advantages. The paradigm investigates MNEs investment location selection in terms of motivations and locational advantages such as large market size, lowcost production factors, natural resources, and strategic assets, which are explicitly referred to as market-seeking (MS), efficiency-seeking (ES), resource-seeking (RS), and strategic asset-seeking (SAS), respectively. In the mid-1980s, researchers classified FDI as horizontal and vertical. MS horizontal FDI seeks to maximize proximity to overseas clients and reduce trade costs (Brainard, 1993). Vertical FDI, on the other hand, allows for the fragmentation of manufacturing operations across nations to attain cost efficiency. The knowledge-capital model (Markusen, 2002) considers both of these motivations and assumes that knowledge-based assets provide firm-level scale economies, which reveals much about FDI from developed economies.
Nevertheless, the growth of EMNEs questions the classic FDI theory of firm-specific ownership to promote foreign investment. Studies advocate that firm-specific or country-specific disadvantages also encourage EMNEs overseas investments (Bhaumik et al., 2016;. Through OFDI, EMNEs strive to integrate with global markets to achieve greater cost-efficiency, technological advancements and managerial skills (Buckley et al., 2022;Wood et al., 2021). Moon and Roehl (2001) challenge the market imperfection theory further by emphasizing ownership imbalances over advantages, insisting that foreign investments seek to rectify imbalances by seeking ownership advantages. According to Ramamurti (2012), EMNEs are yet in the initial phases of internationalization but have plans to catch up. More recently, Hamel and Prahalad's (1989) SAS intent approach has been used to investigate EMNE internationalization motivation to compete in global markets . SAS intent encourages EMNEs to overcome competitive disadvantages by leveraging their distinct ownership advantages (Mi et al., 2020;Nelaeva & Nilssen, 2022). Dunning and Lundan (2008) assert that asset-exploiting motivations encourage EMNEs to invest in developing countries, while assetaugmenting motivations to enhance investing firms' capabilities (Meyer, 2015) drive them to developed destinations. Dunning and Lundan (2008) further propose that transaction costs and ownership benefits draw FDI to institutionally sound and better-governed nations. Besides these benefits, institutions strengthen structural and boundary framework for social interaction, shaping the associated people's behavior and experience. As a result, IB thinkers argue that institutions should be considered explicit situational factors rather than background constraints (Lu et al., 2014;M. W. Peng et al., 2009). North (1990) defined institutions as "rules of a game" or "humanly constructed constraints that regulate political, economic, and social interaction" and classified them as informal or formal. In a community, the business environment is defined by formal institutions with stated norms, such as laws and regulations. In contrast, informal institutions are the constraints individuals in a community impose on themselves to manage their relationships with others, such as tradition, language, conventions, and ideals. Formal institutions facilitate effective economic operations and lower transaction costs (North, 1990). As the varying IE renders a variation in transaction costs across nations (Williamson, 1995), the institutional differences between the host-home country IE exhibit variation in institutional support for economic activities (Beugelsdijk et al., 2018). Hence, ID is deemed a crucial determinant of the transaction cost that affects OFDI decisions. MNEs escape constrained home institutions "institutional escapism" by investing in nations with stronger institutions. Moreover, they participate in institutional exploitation by investing in nations with similar institutional quality (Tang, 2021;Yoo & Reimann, 2017). Thus, the directionality of ID affects EMNEs' FDI location and motivation choice in different ways (Hernández et al., 2018).
The integration of a 21st-century dynamic institution-based view (IBV) proposed by M. W. Peng et al. (2009) with Dunning's eclectic framework advances IB literature (R. Li & Cheong, 2019;McWilliam et al., 2020) and the present study approaches it from an emerging Indian economy perspective. The research assesses seven hypotheses on how institutional and traditional variables affect India's OFDI in emerging and developed regions.

Data & variables
The present study employs PPML methodology to examine the impact of host-home ID on Indian OFDI. Similar to previous research, Indian overseas investment data is retrieved from the RBI's OFDI database (Nayyar et al., 2021;Saikia et al., 2020). Monthly OFDI data is compiled annually based on investment destinations from 2008 to 2018. The sample comprises 107 host nations, 26 developed and 81 developing nations. Outflows to offshore financial centers such as Mauritius, Cyprus, the Netherlands, Panama, and the Cayman Islands are excluded from the study since the final destination of FDI funneled through this route is uncertain and may distort outcomes. The institutional and traditional factors are obtained from reliable databases (Table 1). Until 2012, developing nations were the top destinations for Indian offshore FDI; however, this tendency changed in favor of developed nations post-2012. (Figure 1).

Dependent variable
The annual Indian OFDI (in USD billion) from 2008 to 2018 is sourced from the RBI database. The destination countries are categorized as developing or developed based on the UN's 2 classification.
The two regions with noticeably distinct IE and locational advantages may hinder or encourage MNEs' locational preference (Aleksynska & Havrylchyk, 2013). Hence, to capture these differences distinctively, this categorization is deemed necessary.

Institutional quality variables
Study investigates the influence of home-host ID on Indian OFDI using the WGI. Each of the six major governance indicators, i.e., Corruption Control (CC), Government Effectiveness (GE), Political Stability (PS), Regulatory Quality (RQ), Rule of Law (RL), and Voice and Accountability (VA), indicate a specific facet of nation's institutional excellence. The unbundling of institutional factors allows analysis of their diverse impacts on Indian OFDI across regions. The WGI ranges between −2.5 and +2.5. As multicollinearity between these indicators prevents simultaneous regression estimation, the study examines all six indicators in separate models. We retain the difference sign while estimating the host-home institutional distance (ID). The positive ID sign indicates a preference for robust or better IE, whereas the negative favor weaker or similar IE.
VA assesses citizens' ability to choose their government and freedom pertaining to expression, and media among others (Kaufmann et al., 2009). VA enables the general public to gain information about government performance and voice their opinion. Monitoring and accountability assist the government, and its institutions (public sector) develop effective strategies. However, the incorporation or prohibition of public opinion in investment decisions can either promote or deter FDI (Mondolo, 2019;C. Peng et al., 2021).
PS measures political unrest. It estimates the risk of violent and illegal removal of the ruling government and signifies its capability to retain power. PS induces FDI by making business easier through stable political regimes. Studies widely suggest that a country's political stability  influences FDI (Akin, 2019;Shahzad & Al-Swidi, 2013). Despite popular belief, research also demonstrates that PS has a minimal impact on foreign investors because it is just a prerequisite for commencing investments in small developing countries (Kurecic & Kokotovic, 2017).
RQ reflects the government's ability to design rules and regulations encouraging private-sector advancement (Kaufmann et al., 2009). Furthermore, the effectiveness with which regulations are created and enforced in society determines a country's regulatory system (Mariotti et al., 2021). The host country's eased regulatory burden on investments, operational processes, taxation, and market-unfriendly interventions, such as price control and inadequate banking, is thus regarded as critical determinants of FDI (Kiely, 2020;Sabir et al., 2019).
RL reflects agents' perceptions about the enforcement of contracts, property rights, law, judiciary, violence, and crimes (Kaufmann et al., 2009). Government officials drive the most effective strategy to encourage the rule of law' and institutions' adherence to the rule of law standards in society (Teeramungcalanon et al., 2020). FDI is drawn to countries with a robust rule of law (Kasasbeh et al., 2018;Tiede, 2018). Weaker laws pertaining to property rights protection and legal structures discourage investors from taking risks. Findings suggest that property rights protection laws have significantly influenced FDI in developing nations and the former communist bloc (Q. Li & Resnick, 2003).
CC quantifies the degree to which public authority is exploited for personal advantage. Government corruption undermines foreign investment globally by allowing patronage to trump talent. More FDI generally flows into countries that crackdown on corruption, strengthen the rule of law and protect private property. Corruption creates market inefficiency and escalates production and management costs, jeopardizing FDI (Bhattacheryay, 2020;Lee et al., 2022).
GE evaluates the government's service quality, capacity to design, implement, and adhere to policies and programs, and administrative independence from political restraints (Kaufmann et al., 2009). Ineffective policies hinder economic progress, making the country less attractive to foreign investors (C. Peng et al., 2021;Deng & Yang, 2015). A stable government guarantees policy continuity; hence, government effectiveness and FDI inflows are positively correlated.
As the Indian government continues to improve institutions, research assumes a lot remains to be accomplished. Hence, the paper hypothesizes that Indian OFDI, primarily fueled by private businesses, seeks institutionally distant host countries with robust IE.

H1c: Host countries with stronger RQ in both regions attract Indian OFDI.
H1d: Host countries with stronger RL in both regions attract Indian OFDI.

H1e: Host countries with stronger CC in both regions attract Indian OFDI.
H1f: Host countries with stronger GE in both regions attract Indian OFDI.

Traditional determinants
Based on the existing literature, our model includes key macroeconomic variables that are significant determinants of FDI: GDPsum, absolute GDP per capita difference, availability of natural resources, availability of strategic assets, trade openness, and profit tax rate.
Literature suggests that market size drives horizontal FDI (Zhu et al., 2022;Chiappini & Viaud, 2020). GDPsum is employed as a proxy for horizontal market-seeking (MS) OFDI. The dependent variable should rise if the home country considers the host a larger market. Indian firms' MS motivations are seen in recent acquisitions across regions. For instance, Fab India Overseas acquired UK women's fashion shop East Ltd., and Cox and Kings India acquired Prometheon Holdings. Max, Apollo, and Manipal hospitals have made investments in UAE, Qatar, and South Africa. Study hypotheses:

H2: Indian OFDI is positively associated with the host country's market size in developed and developing economies.
Absolute GDPpcDiff exhibits skill and capital intensity disparities between home-host nations . Based on H-O factor endowment theory, the variable captures the pertinence of vertical or ES FDI by developed market MNEs (technologically advanced) in poorer host countries (with abundant labor & low production costs), also known as labor-seeking FDI (Hong et al., 2019). Technology-difference hypothesis contributes to the H-O's explanatory power, particularly when EMNEs seek technology, managerial skills, and highly skilled labor in the developed economy (Trefler, 1995). Moon and Roehl (2001) established the concept of imbalance against advantage to explain the unconventional FDI flow from poor source nations to wealthier host countries. Hence, EMNEs invest overseas to offset competitive shortcomings.
Asset-enhancement FDI, which seeks strategic assets to support a cheaper workforce, is similar to vertical FDI, which strives for a cheap workforce to support a country's strategic assets, as long as new MNEs can effectively use the acquired assets (Ghahroudi et al., 2018). Since technology is generally associated with economic advancement, developed countries are appealing destinations for EMNEs seeking strategic assets to support cheaper labor (Athari & Adaoglu, 2019;Gao et al., 2019;James et al., 2020). As the study examines South-South and South-North OFDI, the variable's coefficient is expected to be negative for developing nations indicating low cost (efficiency) seeking investments, and positive for developed nations indicating ES motive for asset augmentation, known as SAS intent (& Y. Kang et al., 2021). The asset-augmentation perspective, 3 posits that EMNEs transcend global competition by acquiring knowledge-based strategic assets (Buckley et al., 2016;Yang et al., 2022). They use internationalization as a "springboard" for their future growth (Luo & Tung, 2007). This argument is supported by Tata and Suzlon's foreign acquisitions. Tata Steel became the fifth-largest global steel manufacturer after acquiring Corus, while Suzlon became the fifth-largest wind turbine producer after acquiring RE Power and Hansen (Buckley et al., 2016). Thus, it is hypothesized that: H3: Indian OFDI is positively associated with efficiency-seeking motivation in developed (assetaugmenting) and developing nations (low-cost).
The percentage of ores and metals exports to merchandise exports is used to estimate natural resource availability (Nresources). Rising resource costs and economic expansion have boosted competition for resources. Historically, MNEs leveraged overseas production facilities to gain host resources (& Y. Kang et al., 2021). India's RS OFDI flows across regions, such as ONGC in Azerbaijan, Colombia, Brazil, Russia, Adani Group in Australia, Sun Petrochemicals and Reliance India in the USA (Varma et al., 2020). Flexible environmental policies in developing as opposed to developed economies foster RS investments (Contractor et al., 2020;Sutherland et al., 2020). Recent environmental protest over Adani's Australian coal mine project is relevant to the argument. Owing to growing RS investments in both regions, the study hypothesizes that: H4: Indian OFDI is positively associated with the availability of natural resources in developing and developed economies.
Patent and trademark filings by residents indicate a country's technological prowess and are a proxy for host country's strategic assets (Nayyar et al., 2021;Sutherland et al., 2020). SAS firms either augment home-country knowledge with host-country expertise or generate new knowledge. This classifies SAS FDI by asset type. Kuemmerle (1997) postulates that home-base augmenting FDI substitutes deficient home-based knowledge with foreign knowledge. MNEs build overseas R&D to bolster domestic innovation and output. Home-based FDI integrates R&D with location-specific knowledge to create new businesses. From 2008 to 2018, developed nations attracted Indian OFDI in high-tech while developing in medium and low-tech (Joseph, 2019). High-innovation firms are proactive in leveraging external innovation, while low-innovation firms are reactive or passive (Y. Li & Rengifo, 2018). The study assumes that the high innovation capabilities of the Indian MNEs promote assetexploiting SAS investments; hence we hypothesize that:

H5: Indian OFDI is positively associated with the availability of strategic assets (asset-exploiting) in developed and developing economies.
Trade Openness (TO), representing a liberal economic orientation, boosts FDI (Le & Kim, 2020). Trade share as a percentage of GDP measures trade openness. Free-trade environments in host nations enable MNEs to learn about local market conditions through FDI (Sajilan et al., 2019). Assuming that globalization and liberalized trade policies affect economic activity and attract FDI, the study hypothesizes that, H6: Indian OFDI is positively associated with trade openness in developing and developed economies.
The effect of tax on FDI, proxied by total tax rate as a percentage of commercial profits, is widely used in empirical studies (Abdioğlu et al., 2016). Foreign investors seek to enhance their earnings after tax by transferring investments to countries that offer more tax benefits 4 (Sanjo, 2012). The study hypothesizes that, H7: Indian OFDI is negatively associated with higher taxes in developing and developed nations.

Econometric estimation
Traditionally the log-linearized models were widely estimated by a linear estimator such as OLS. The natural logarithm is taken on both sides to arrive at the log-linearized model. However, OLS is subject to econometric issues. As OFDI assumes non-negative values, linear OLS cannot ensure non-negative predicted values. The problem of negativity can be resolved by applying natural log transformation to both sides. Nevertheless, this methodology works only with positive dependent variables, however in our dataset the OFDI flow to certain nations is zero for some years. The log-linearized model forces the truncation of zero-value observations because the log-linearization is not possible if y i = 0 since ln 0 = -∞. Furthermore, the predicted log-linear residual value will depend on the vector of covariates even though all observations of yi > 0. Consequently, OLS estimates are incongruent. Excluding zero-trade observations creates a truncated dependent variable, resulting in selection bias. Missing data can influence test outcomes and result in skewed conclusions. Silva and Tenreyro (2006) recommended employing the Poisson-Pseudo Maximum Likelihood (PPML) methodology to estimate the nonlinear model. Researchers prefer Poisson regression with robust standard errors over log-transformed OLS linear regression. PPML ensures that fixed effects are equivalent to structural terms even with heteroscedasticity and high zero occurrences. PPML estimation with robust standard errors does not assume E(y i ) = Var(y i ) nor requires Var(y i ) to be constant across all i. Thus, the PPML estimation with robust standard errors (Huber-White-Sandwich linearized variance estimator) is the best alternative to loglinear regressions (Motta, 2019).
Therefore, PPML the optimal estimator, is employed in our study.
Our baseline PPML model is as follows: where OFDI ijt is the measure of OFDI flow from home country i to host country j in year t lnGDPsumt ijt (natural log) representing Market, is the sum of GDP of country i and country j in year t |GDPpc it -GDPpc jt | (natural log) representing Efficiency is the absolute difference between the GDPpc of country i and country j in year t lnTax jt (natural log) represents tax rate in the host economy, measured by the total tax rate expressed as a percentage of commercial profits.
Metals represent natural resources (Nresources). The proportion of ores and metals exports as a percentage of merchandise exports is used as a proxy for Nresources.
lnpatents represent strategic assets. The total number of patent and trademark applications filed by a country's citizens divided by the country's population is used as a proxy for this statistic.
TO represents trade openness of the country measured by the proportion of exports + imports to GDP.
IQ jt comprises institutional quality variables represented by World Bank's six governance indicators, examined individually across six models δ t represent a set of year dummies capturing time FE θ t are host country dummies that capture host country FE. ε ijt is the error term of the estimation The RESET test is employed to ensure that PPML's conditional mean is correctly specified (Ramsey, 1969). The Time FE model eliminates omitted variable bias by removing unobserved variables that vary but are consistent across entities. Country FE, on the contrary, estimates withincountry variance and controls time-invariant country-specific factors. The results are computed controlling for time and country FE, which absorb unobserved heterogeneity and economic and contextual factors (Mariotti et al., 2021).

Empirical results
Our sample of 107 host nations is divided into 26 developed and 81 developing economies, following the UNCTAD classification (Appendix Table A1).
The descriptive and correlation statistics for developing and developed regions are reported in Tables 2 & Table 3, respectively. Due to the high multicollinearity between governance factors, they are all separately modeled. There is no multicollinearity issue because the variance inflation factor value for all explanatory variables across models is reported to be less than 10 (Hair et al., 1998). To avoid the simultaneity problem or reverse causality, time-varying variables are lagged by one year. Our PPML estimation for both developed and developing category models clears the RESET functional test (Prob > chi2 > 0.05). The findings of each region's best estimators are discussed.

Results controlling for country & time FE
The findings (Table 4) fully support H3, proving that asset-augmenting vertical FDI or efficiency seeking intent significantly motivate Indian overseas investments in developed nations. Rather than focusing on lower unit labor costs, this efficiency-seeking strategy aims to build new competitive advantages by merging the best global technology with low-cost Indian labor (Buckley et al., 2016).
Findings reveal that asset exploiting SAS motivation (H5) is not a significant motivation for Indian investors in the developed region. Our findings support previous research indicating that the unconventional internationalization path taken by EMNEs lacking advanced technology and managerial capabilities is motivated by a desire to augment firm's existing capabilities (Meyer, 2015;Stefano & Santangelo, 2017). Trade openness (H6) is found to promote Indian OFDI significantly. Studies suggest that the host country's high trade openness attracts MNEs with efficiency-seeking (asset-augmenting) motivation to integrate into global value chain configurations (Behera & Mishra, 2022;Paul & Jadhav, 2019). The higher taxes have a negative but insignificant impact on OFDI. Hence, hypothesis H7 could not be proved. Tax haven countries (not part of the study) are the preferred investment destinations to overcome the tax burden; thus, the tax does not appear to be a significant factor influencing OFDI.
Investors are inclined towards robust IE (all β coefficients of WGI are positive); however, robust RQ (H1c) (β = 0.517, p = 5%) and CC (HI e) (β = 0.376, p = 5%) significantly drive OFDI (Table 4). Our findings corroborate previous research (Joffe, 2017;Prasad & Rajan, 2008), which contends that the robust IE in developed countries vis-à-vis home country is a significant motivator for investors. The leading reasons for overseas investments are inadequate infrastructure, poor institutional and financial setup and low-skilled labor. Moreover, as India's stifling regulatory environment (RQ) creates uncertainty, drives up firms' expenses, and impedes competitive advantage growth, it becomes even more critical for Indian MNEs to invest in nations with superior RQ (Nayyar & Prashantham, 2020). Similarly, to overcome the uncertainty in decision-making, unlike Chinese firms, Indian MNEs prefer to invest in the least corrupt nations (Qureshi et al., 2021).

Results controlling for country & time FE
The findings (Table 5) suggest that Indian OFDI is significantly driven by the market(H2) motive in developing nations. Similar findings are reported by Varma et al. (2020). Trade openness (H6) has the expected positive sign but did not reach the required significance level. Higher TO allows exporting enterprises to grasp the host market and regulatory provisions, overcome linguistic and cultural barriers, organize operations, and market their products internationally (Cieślik & Tran, 2019). Nevertheless, the literature also highlights that the FDI-trade association is complementary for ES projects and substitutive for MS ones (Swenson, 2004). Hence, the prominence of MS motivation may explain the variable's insignificance in this scenario. Overall, investors are   inclined towards robust IE (β values positive but insignificant), but none of the WGI is found to influence OFDI significantly. This could be justified on the ground that developing nations largely have an IE relatively similar to India's. However, the interaction of WGI with investment motivations (next para) reveals that Indian investors prefer host countries with specific investment climate (factors) when driven by specific motivations. Surprisingly, higher taxes (H7) do not deter OFDI in the developing region but promote it. This could be justified by arguing that a relatively light tax burden cannot make up for an overall weak or unattractive FDI environment. When a higher tax burden is offset by strong infrastructural facilities and other country-specific characteristics such as large market size, countries with low taxation regimes have little influence on location choice (Johansson et al., 2008).
The interaction of ID*MS (Table 5a) suggests that robust RQ (β = 0.017, p = 1%) and RL (β = 0.014, p = 5%) moderates MS investments. Findings suggest that good governance and transparent, predictable judicial frameworks can boost FDI in developing economies. The World Bank's (2017) survey also reports a business-friendly legal and regulatory environment driving investments in developing nations. None of the WGI was found to influence the ES and SAS motivation of Indian OFDI. On the contrary, weaker (similar) VA (=−0.025, p = 10%) and PS (=−0.024, p = 10%) attract RS investments (ID*RS) due to reduced competition and a better likelihood of success. Our findings concur with past studies that robust democratic rights enhance the economy, but incorporating public opinion into investment choices hinders foreign investment, especially in mining or natural resource sectors (Jain & Thukral, 2022;Sabir et al., 2019;Teeramungcalanon et al., 2020).     Note: Std. errors in parenthesis. ***, ** and * indicates significance of coefficients at 1%, 5% and 10%, respectively

Robustness check
We assess robustness by omitting the nations with the highest OFDI in developed (USA) and developing (Singapore & UAE) regions. The findings remain qualitatively the same and are reported in Table 6 and Table 7. We also performed negative binomial regression, an additional robustness test to identify primary motivational and institutional determinants. The results were found to be consistent. To maintain brevity, results are not reported but are available upon request.

Conclusion
The study extends the understanding and knowledge of significant Indian OFDI determinants, both motivational and institutional, differentiated by regional destination. Findings overall demonstrate a positive association between Indian OFDI and the host country's robust governance quality (excluding RS investments in developing regions). Robust RQ and CC in developed nations are the primary IQ determinants significantly attracting Indian OFDI. However, none of the WGI significantly influences OFDI in developing countries. The study proposes asset augmentation as the primary motivation for Indian OFDI in institutionally distant, robustly regulated (RQ), and least corrupt (CC) developed nations. Moreover, these qualities are also preferred by SAS (asset exploitation) and MS investments. Nevertheless, the RS investments prefer institutionally distant developed nations with more robust VA, PS and CC. Market seeking is the primary motivation for Indian OFDI in developing regions. Although investors overall prefer robust IE in developing countries, it is not a significant determinant. Nonetheless, the interaction effect indicates that strongly regulated (RQ), rule-based (RL) developing economies are significantly preferred by only MS investors from India. On the contrary, RS investments are largely driven to developing nations with weaker IE concerning PS and VA.
Findings reveal a significant difference between Indian and Chinese OFDI patterns. Unlike in India, the host country's governance quality has a negative impact on Chinese OFDI (Fon & Alon, 2022). Because of their prior home experience in dealing with corruption, political instability, and accountability, Chinese MNEs do not hesitate to operate in economies with unstable IE (Kolstad & Wiig, 2012). Additionally, the availability of concessional Chinese subsidies and loans also strengthens the risk ability of Chinese businesses to engage with weakly regulated economies (Lu et al., 2014). Furthermore, SAS MNEs from China heavily rely on innovation and knowledge-based ownership advantages (Mi et al., 2020). This explains why more Chinese MNEs invest in developing economies (asset exploitation & RS motive) vis-a-vis Indian OFDI (asset augmentation motive) in advanced countries (Zhu et al., 2022).
The significant OFDI activity in developed countries (USA, UK, Germany, and Australia) by Indian firms, mainly since 2014, is attributed to Prime Minister Modi's foreign policy and Indian MNEs' ambitions to acquire strategic assets and innovative technologies (asset-augmentation; Hall & Ganguly, 2022). The government's "Make in India" strategy and institutional backing have boosted domestic manufacturing through knowledge-intensive international initiatives (Zhu et al., 2022). Nevertheless, the low innovation capability of Indian MNEs raises concerns about ownership disadvantages (Buckley et al., 2016). EMNEs internationalise to establish competitive advantages by enhancing strategic assets and resources, which may increase global competitiveness but is insufficient to match international leaders with better strategic assets (Cui & Xu, 2019). Thus, the Indian government should invest heavily in R&D to support strategic corporate behaviour, such as collaborative research and technological improvement, because firms with excellent innovation abilities are better at obtaining and assimilating new information (Kang et al., 2021;Athari et al., 2020). Firms' innovation skills encourage integrating existing and new knowledge derived from SAS behaviour, boosting innovation performance. Chinese MNEs with advanced technology and industrial prowess have had greater success in acquiring advanced strategic assets abroad (Deng et al., 2022).
The findings suggest that policymakers in developing countries should prioritise improving governance to attract FDI. Countries with strong institutions, good governance, and transparent and stable legal regimes are the preferred investment destinations even for emerging nations MNEs (except RS investments in developing region). In terms of managerial and practical ramifications, this study offers Indian investors an intriguing viewpoint on their strategic decisions in various international locations. Our findings help them understand the factors that influence investment across regions better.
