A discussion on construct definition and measurement and its relation to performance

Purpose – The purpose of this paper is to discuss the different approaches to the corporate reputation construct, in order to identify a comprehensive definition that can be used for measurement purposes, gaps identified by previous literature identified. Design/methodology/approach – This is a theoretical essay. The authors analyzed studies that involve the relationship between corporate reputation and organizational performance, and the attributes of national and international corporate reputation ratings. Findings – The authors identified a more comprehensive definition for the reputation construct, and indicated courses for the construct’s measurement, by considering: the judgment by the stakeholders (internal, suppliers, clients and the financial market); periodical evaluations under different organizational perspectives; attention to theoretical assumptions, among other aspects. Research limitations/implications – The study is a theoretical paper that presents that the research field has many definitions that cannot be used interchangeably. It indicated how the reputation construct should be operationalized for measurement purposes. This study presented a reflection on the relationship between corporate reputation and performance, showing that it is not a settled topic in the academy. Practical implications – The study advances the understanding of the reputation construct measurement, considering the adopted definition and the discussion of the attributes of the main ratings on corporate reputation. The adoption of a measurement method that takes into account the definition used in this study and the features of the methodologies discussed will improve the corporate reputation assessment. Social implications – Literature indicates that a good corporate reputation can affect organizational performance and the inverse relationship is also true. As a social implication, it is extremely relevant to improve the understanding the definition and measurement methods of this construct. Originality/value – This study discusses one of the most important intangible resources for organizations, contributing to the understanding of the difference between the market value and the book value of public companies. Besides it should be considered that there is one lack of a definition directly related to the measurement of the reputation construct in the literature, a gap in which this study contributes.


Introduction
The central goal of strategic business management is to understand why some organizations perform better than others (Crook et al., 2008). Thus, knowing the factors that explain the heterogeneity in companies' performance is one of the main concerns of the theorists in this field of research. One approach for this understanding is called the resourcebased view (RBV ), whose unit of analysis is the resources and capabilities controlled by organizations. Barney (1991), one of the pioneers of this approach, described that resources will provide competitive advantage to the organization that holds them, as long as they are valuable, rare and difficult to be imitated and substituted.
Tangible and intangible resources present in RBV include all the attributes that enable the organization to define and implement strategies, and can be divided in four types: financial resources (equity, retained profits, third party resources, among others); physical resources (machinery and real estate, for example); human resources (experience, employees' intelligence, among others); and organizational resources (teamwork and trust, for example) (Barney and Hesterly, 2009).
Some authors argue that intangible resources are the drivers of organizational performance (Zigan, 2013). This finding confirms RBV assumptions, because due to the phenomenon of causal ambiguityinherent to intangible resourcesit becomes difficult to identify and isolate the resources, as well as to measure the performance achieved through them; thus, one competitor could hardly decode and develop resources similar to those belonging to another competitor (Fernández et al., 2000). Therefore, intangible resources would be the most difficult to imitate and substitute, and possibly would be considered the rarest and most valuable, providing competitive advantage and superior performance to the organization (Brahim and Arab, 2011). Likewise, corporate reputationregarded as one of the main intangible resourcesis seen as a driver of organizational performance and has received attention from the academy in the last decades (Vance and De Angelo, 2007).
In the Brazilian business scenario, we identify cases that show the impact of intangible resources on organizational performance, considering the relationship between corporate reputation and the organizations' value. Investigations about activities carried out by the top management of Petrobras (one of the largest Brazilian companies) weakened the company's reputation, due to accusations of corruption, which resulted in the depreciation of its shares by more than 40 percent, between 2014(InfoMoney, 2016. In this context, in order to positively influence the company's reputation, top management has invested and will continue to invest in its intangible resources, through an advertising campaign launched in the first quarter of 2015, whose central theme is overcoming (Petrobras, 2015).
Conceptually, corporate reputation can be defined as the collective perception of the organization's past actions and expectations regarding its future actions, in view of its efficiency in relation to the main competitors (Fombrun, 1996;Fombrun and Rindova, 2001;Walker, 2010). Some authors state that corporate reputation affects organizational performance, while others argue the opposite: organizational performance affects corporate reputation. Flanagan et al. (2011) studied the relationship between the evaluations of Fortune Most Admired Companies (FMAC) and the economic-financial performance of the organizations, and found that the relationship between corporate reputation and performanceinitially identified by Brown and Perry (1994) still exists, even if weakened.
Besides different interpretations on the relationship between corporate reputation and organizational performance, some aspects of corporate reputation still require additional research, among which are: the definition; and the construct measurement (Barnett et al., 2006;Walker, 2010;Whetten, 1997). Thereby, the objective of this paper is to discuss the different approaches of the "corporate reputation" construct, in order to identify the most comprehensive definition that can be operationalized for measurement purposes. From there, we have examined studies on the relationship between corporate reputation and organizational performance. In addition, we have evaluated the features of national and international corporate reputation ratings, in face of the scientific production related to the subject.
To that end, the theoretical basis of the study was built from the articles published in one of the main journals of corporate reputation, the Corporate Reputation Review, and from other papers quoted in those articles, thus providing a significant set of relevant and current studies on the topic of interest.
The proposed objectives represent relevant concerns, given the importance of intangible resources for organizations. In addition to being recognized as drivers of organizational performance, they contribute to the understanding of the difference between the market value and the book value of public companies (Amadieu and Viviani, 2010;Boj et al., 2014;Kumar, 2009;Perez and Famá, 2006;Vomberg et al., 2015;Zigan, 2013). In this sense, corporate reputation, one of the main intangible resources, plays a prominent role (Ciprian et al., 2012;Gök and Özkaya, 2011). Besides the aspects described, it is important to mention the low density of studies on corporate reputation in Brazil, and the lack of a definition directly related to the measurement of the reputation constructwhich value the proposed contributions (Feitosa and Garcia, 2016).
2. Literature review 2.1 RBV In the late 1950s, Penrose developed an analysis of the firmas the company is often referred to by economistsbased on its ability to create strategies, which can be seen as a counterpoint to the assumptions defended by neoclassical scholars, who stated that the firm only adapted itself to the market. The author claims that firm's growth is determined by managing the set of internal productive resources. This is an evolution in understanding the firm as discretionary, that is, it defines its strategy. The firm's conduct and its strategies would then be established by its internal elements/resources. Besides, the firm would change the market structure, whereas, in neoclassical economic theory, it would be guided by it (Penrose, 2006).
Penrose's analysis of internal resources emerged as an answer to the limitations of classical strategy models, stemming from the Structure-Conduct-Performance paradigm, in responding why companies in the same industry have heterogeneous performances (Kumlu, 2014;Villalonga, 2004). Wernerfelt (1984) and Rumelt (1984) also contributed to the identification of internal resources as drivers of competitive advantage. Wernerfelt (1984), Rumelt (1984) and Barney (1991), among others, defended the assumption that organizational performance is defined by strategic resourceswhich are rare, valuable and difficult to imitate and substitute (Barney, 1991;Zigan, 2013). Prahalad and Hamel (1990) also collaborated in the analysis of strategic resources, by introducing the concept of core competences, which are made up of resources that are carefully allocated by management, and have heterogeneous performances.
Tables I-III present a summary of the main authors and their contributions to the RBV, according to each stage, namely, introduction, growth and maturity.
The introduction stage marks the beginning of the theoretical building of RBV, and the elaborations of key concepts as a consequence. Starting with the discussion of the internal elements of the organization (Penrose, 2006), the authors added contributions in order to build the foundations of this approach. At this stage, the relationship between strategic resources and organizational performance was not clearly addressed, unlike what is observed in the growth stage, in Table II (Coff, 1999;Miller and Shamsie, 1996;Oliver, 1997).
In the growth stage, new concepts emergedynamic capabilities, knowledgeand branches of RBV arise, such as the natural resource-based view (NRBV) and the knowledge-based view (KBV). NRBV argues that there are three key strategic capabilities that represent sources of competitive advantage, namely, pollution prevention, product stewardship and sustainable development. Its argument is that RBV does not explore the relationship between the organization and the natural environment (Hart, 1995;Hart and Dowell, 2011). KBV, in turn, overcomes the traditional concepts of strategysuch as strategic choice and competitive advantageand explores fundamental concepts of the theory of the firm, such as internal management, organizational structure, innovation theory, among other aspects (Grant, 1996).
In addition, RBV starts to "talk" with other theories, like the institutional theory and the evolutionary perspective, thus becoming a multidisciplinary approach, according to Table II. The maturity stage provides additional contributions to RBV foundations. At this stage, some authors have already considered it as a resource-based theory and not just a RBV. Researchers at this stage focused their attention on intangible resources (Gavetti, 2005;Makadok and Barney, 2001;Makadok, 2001;Teece, 2007), which are the drivers of business performance, with corporate 49

Likewise, the diversity of concepts related to corporate reputation shows the lack of a definition that allows to advance toward the measurement of the reputation construct, which is the central goal of this study.

Intangible resources
An organization is made up of tangible and intangible resources. Examples of tangible resources include real estate and inventory of an organization, listed in the accounting statements. Intangible assets, in turn, are generally not measured in accounting reports (Carmeli, 2004;Hall, 1993). Barney (2001), one of RBV pioneers, described that resources and capabilities can be seen as a set of tangible and intangible assets, including managers' skills, organizational processes and routines, as well as information and knowledge controlled by the organization.
For Hall (1993), intangible resources can be classified as assets or competences. As intangible assets they include the intellectual property of patents, trademarks, copyrights and registered projects. With regard to skills, they comprise the know-how of employees, suppliers and distributors, and organizational culture. Hall (1993) classified intangible assets in: (1) Capacities that configure the organization's ownership, such as patents; and capacities that refer to the competence to develop a particular activity, such as the know-how.

(3) Intangible resources that can be protected by legislation, such as trademark; and intangible resources that cannot be protected by legislation, such as organizational networks. Fernández et al. (2000) used the classification developed by Hall (1993) and created a typology for intangible resources, considering the resources that are dependent on people and those that do not depend on them, shown in Table IV. Some authors observe that the interest in resources and intangible assets has intensified in the last three decades; previously the greatest concern of strategy was tangible assets. Mohr and Batsakis (2014) agreed, and described that intangible resources such as brands, clients' lists, patents, knowledge and skills are those that meet the assumptions of strategic resources defined by Barney (1991) rare, valuable and difficult to be imitated and substitutedand play a central role in explaining companies' competitive advantage.
As of the 1990s, there was a greater separation between the book value and the market value of companies, due to processes of mergers and acquisitions between companies, and the existence of unaccounted intangible assets (Lev, 2005;Perez and Famá, 2006). Part of the difference between the book value and the market value of companies is due to corporate reputation. In this sense, some studies have examined the relationship between corporate reputation and organizational performance, through different methodologies/ratings, in order to contribute to the understanding of the influence of intangible resources on organizational performance, as we discuss in the following sections.

Corporate reputation
Scholars and managers believe that a good reputation is an organization's most valuable intangible resource, for the following reasons: it reduces stakeholders' uncertainty about the organization's future performance; it strengthens competitive advantage; and it contributes to the target audience's trust and to value creation, maximizing the ability to offer products and services with high added value (Gök and Özkaya, 2011;Vidaver-Cohen, 2007). Regarding corporate reputation, there are different streams of thought. The first one refers to social expectationsmore precisely, to those that people have about the organizations' behavior. Reputation measures, such as those published by Fortune magazine -Fortune Most Admired Companies (FMAC)and the Reputation Quotient (RQ), published by the Reputation Institute, include some examples of this stream of thought. The second stream is based on the concept of Corporate Personality, that is, the personality traits that people attribute to organizations. Davies et al. (2003) made a contribution, using concepts related to the image and identity of organizations to assess their personality. The third stream of thought uses the concept of trust as a starting point, taking into account the perception of the organization's honesty, reliability and benevolence as the main elements. The scale named Corporate Credibility, developed by Newell and Goldsmith (2001), is an example of this approach (Berens and Riel, 2004).
By analyzing the literature on corporate reputation, we noticed that more attention has been given to the first and second streams of thought. The next sections discuss concepts, different applications and ways of measuring the reputation construct.

Construct definition
Constructs are concepts without a corresponding empirical variable (Bunge, 1973). No one can see or touch another person's intelligence, although it is possible to identify it (measure it) by how an individual solves a given problem, compared to how others solve it (Safón, 2009). Therefore, corporate reputation can be said to represent a construct, since it does not have a single corresponding empirical variable; thus, it is essential to understand the definition of this construct, before using it in applied academic research.
Charles Fombrun was a pioneer author on the topic of corporate reputation. For him, it is a subjective concept, which can be defined as the collective (aggregate) judgment about the effectiveness of a company, comparing its past actions and future projections based on a pre-established pattern (Fombrun, 1996;Fombrun and Rindova, 2001;Walker, 2010).
In order to contribute to the construct definition, Bennett and Kottasz (2000) examined definitions of corporate reputation and identified 16 different ones, among articles published in scientific journals and studies in general, which proved the diversity of related concepts.
It is worth mentioning that the definition of the construct "corporate reputation" is different from other concepts such as organizational identity and image, although they have been used interchangeably in the literature (Walker, 2010). Table V compares the three elements: organizational identity, organizational image and corporate reputation.
Considering that corporate reputation is defined as an aggregate perception from internal and external stakeholders, it is possible to conclude that a single reputation rating must exist for each company, unlike organizational image and identity, which can be  (Walker, 2010). In order to contribute to the definition of the reputation construct, Barnett et al. (2006) analyzed the different existing definitions, using 49 research sources (books and articles), from which they identified three groups of definitions, named assets, evaluation and knowledge or perception. One of the main contributions of the authors is a definition for the reputation construct, described as: the collective judgment of an organization by observers, based on financial, social and environmental assessments made over time. The concept defined by Barnett et al. (2006) is comprehensive and contributes to the understanding of the elements that should be considered in measuring the reputation construct; therefore, it was chosen as the guiding line for the discussion proposed in the following sections.

International ratings
In the context of the first stream of thought addressed in Section 2.3, which refers to expectations regarding the behavior of organizations, we discuss the similarities and differences of corporate reputation ratings in the literature.
Fombrun (2007) developed a survey to identify corporate reputation ratings used in 38 countries. As a result, he found 183 different ratings (lists) and made some inferences, among which: (1) 61 lists resulted in a ranking of a set of companies, based on a general measure of reputation; (2) 73 lists focused on assessments of workplace quality; (3) 15 lists had ratings based on attributes related to employees; and (4) 11 lists rated companies, by considering some subjective assessments on the financial performance and future scenarios of the companies.
There was a predominance of ratings that use a formative construct to measure corporate reputation (a general measure of reputation), as well as a significant presence of indicators that assess the quality of the workplace. Employee-related aspects and evaluations of future perspectives and financial performance of organizations were also found. Regarding the main criterion used by the rating lists, the author mentions the following elements, in descending order of importance: reputation in general, workplace, citizenship, performance, leadership, innovation, governance and products.
Table VI presents some of the main international ratings.
The literature on corporate reputation shows a frequent participation of the ratings published by Fortune magazine (FMAC) and those achieved through the RQ, provided by the Reputation Institute for different countries (Chetthamrongchai, 2010;Hillenbrand and Money, 2007).
As regards the influence that each of these ratings has on reputation, Fombrun (2007) recommended that users carefully evaluate how these ratings were conceived, following these steps: identify the rating context; assess changes in companies' ratings over time; compare the ratings of competitors in the same industry; investigate the coverage of the publication and its readers; and review and compare different methodologies.
Considering the definition by Barnett et al. (2006), we should add to Fombrun's recommendations the need to assess which organizational perspectives (financial, social and environmental, for example) were considered in the ratings, as well as the stakeholders involved in the evaluations. Regarding the literature on corporate reputation, the set of stakeholders most cited in the surveys are the internal audience (executives and employees), customers, suppliers and the financial market (market analysts), who represent a significant part of the organizations' observers (Barnett et al., 2006). Fombrun's (2007) study also presents the main ratings related to corporate reputation used in Brazil, which are shown in "Ratings used in Brazil": In Brazil, some reputation ratings have been used as proxies[1] for corporate reputation. When examining the studies on this topic, we certified the academic recognition of the surveys made by magazines Exame, Você S/A and Carta Capital (Caixeta et al., 2011).

Ratings used in Brazil
Some researchers question the national and international ratings discussed so far, for two reasons. First, because the criteria used in the evaluations do not have a consistent theoretical basis. Second, because survey respondents are, in general, executives and market analysts. Thus, critics understand that the ratings derived from these analyses are highly dependent on firms' financial performance (Davies et al., 2001). Such criticisms are in line with the definition of the reputation construct, supported by Barnett et al. (2006) and used in this study, which recommends that the evaluation should consider the financial, social and environmental perspectives of organizations, without indicating which one is more relevant than the other.
Because of the mentioned questioning, Fombrun et al. (2000) proposed an alternative form of measurement, the RQ, which has seven dimensions of reputation taken from the literature: performance, products and services, innovation, leadership, work environment,

55
Corporate reputation citizenship and governance. RQ contributes to overcome the criticism regarding the theoretical foundation, but is usually employed to assess the perception of external stakeholders about the organization, which may be seen as a limitation, in the light of the definition adopted in this study and the findings of Davies et al. (2001), Wiedmann and Buxel (2005) and Chetthamrongchai (2010).
In the next section, we specify some criteria related to the measurement of the reputation construct, using the definition proposed by Barnett et al. as a guide.

Construct measurement
As mentioned earlier, in the literature on reputation the presence of the rankings published by Fortune magazine (Fortune Most Admired Companies (FMAC)) and by the Reputation Institute (the RQ) is frequent, as corporate reputation assessments (Chetthamrongchai, 2010;Hillenbrand and Money, 2007).
FMAC scale includes the perceptions of executives and (market) financial analysts about human resources management, quality of products and services, long-term investments, management quality, innovation, financial soundness, use of assets and corporate social responsibility. The RQ considers seven dimensions, namely, performance, products and services, innovation, work environment, governance, citizenship and leadership, and can be used to get information on corporate reputation from the standpoint of customers, employees, suppliers and/or investors. The Corporate Personality Scale, in turn, deals with the perception of customers and employees about the organization's personality, assuming dimensions such as competence and courtesy (Hillenbrand and Money, 2007).
When examining the definition of reputation adopted in this study, we perceived some limitations in the use and/or adaptation of these ratings. One of them is that they only consider in the evaluations the opinion of executives and market analysts, of clients and collaborators, or of one stakeholder (Davies et al., 2001). The definition of the reputation construct adopted in our study refers to the collective judgment by the observers of an organization; hence, the measurement of a company's or group of companies' reputation should include the judgment by a representative portion of the stakeholders, involving the internal audience (executives and employees), and also customers, suppliers and the financial market (market analysts).
The conclusions achieved by Wiedmann and Buxel (2005) and Chetthamrongchai (2010) confirm the above arguments. Wiedmann and Buxel (2005) described that corporate reputation should be seen as the result of perceptions and evaluations from customers, investors, employees and the general public, regarding performance, products and services; therefore, considering the view of just one stakeholder is not sufficient. Chetthamrongchai (2010) sought to validate the RQ and Corporate Character Scale in Thailand, by considering a sample of customers of the company Tesco Lotus. After identifying the lack of a collective judgment by stakeholders, he suggested the inclusion of other stakeholders' opinions, such as employees, in future studies.
Another aspect that should be taken into consideration when measuring the reputation construct regards the perspectives to be used. The definition of the construct adopted in this study embodies financial, social and environmental assessments of the organizations, and does not assign a higher weight to either perspective. In this sense, some authors criticize the FMAC scale, for being highly dependent on the organizations' financial performance (Davies et al., 2001).
The longitudinal element should also be present when measuring the reputation construct, since the definition includes financial, social and environmental assessments of organizations over time. Thus, ratings/measurements based on indicators assessed during one given year would not meet the theoretical assumption. It is important to add that primary data, collected through research instruments and interviews, should be used to measure the reputation construct, since the definition refers to the collective judgment by observers of an organization, which would hardly be achieved through secondary data.
Individual beliefs about firms may not be equal to the meaning or to the sum of guidelines given by researchers. This can be particularly troublesome when corporate reputation is modeled as a formative construct rather than a result of a reflexive construct (Ponzi et al., 2011). Theoretical assumptions should be weighed in building scales to measure the reputation construct, and these should be examined through statistical criteria (exploratory and confirmatory factor analysis, for example), in order to identify whether the concepts used were properly understood by respondents, and if they really measure what is expected. When the construct is formative, it becomes more difficult to meet the required theoretical and methodological criteria, since we assume that the sum of the concepts/indices contemplated is the result of the construct object of this study (first-order construct). Table VII summarizes the main methodologies for assessing corporate reputation, considering their inherent advantages and disadvantages.
A measurement method that is aligned with the definition adopted for Barnett et al.'s corporate reputation construct and also with the attributes of the methodologies presented in Table VII should consider: the collective judgment by a representative part of the organization's stakeholdersinternal (executives and employees), suppliers, customers and market analysts; the use of different organizational dimensions/perspectives (financial, social and environmental) in the evaluation; systemic (longitudinal) assessments of corporate reputation; theoretical assumptions in building the evaluation scale; and the understanding that stakeholders may have different perceptions about the reputation of organizations.
The adoption of a measurement method that takes into account the definition used in this study and the features of the methodologies discussed will allow to advance the discussion on the measurement of corporate reputation, addressing the criticisms of the literature. Among them, we can mention: the judgment by executives and market analysts, by customers and collaborators or by just one organization stakeholder (e.g. clients or employees) (Chetthamrongchai, 2010;Davies et al., 2001;Wiedmann and Buxel, 2005); the allocation of a higher weight to the financial perspective (financial performance of the organization) than to the other perspectives (Davies et al., 2001); and the weak theoretical basis in building the scales to measure the reputation construct (Ponzi et al., 2011).

Relationship between reputation and corporate performance
In order to contribute to the understanding of the scenario that involves corporate reputation, we discuss one of the main theoretical assumptions inherent to the topic: corporate reputation Corporate reputation as a driving element of organizational performance. In this debate, we refer to studies that address this relationship, and consider limitations identified by different authors. Corporate reputation is acknowledged as a multifaceted term, with different meanings for distinct disciplines and perspectives. For writers on strategy, corporate reputation can be seen as a resource that generates competitive advantage. For accountants, it is an intangible asseta type of goodwill[2]whose value oscillates in the market (Wiedmann and Buxel, 2005). Knowing that there is a financial reward for investing and keeping a good corporate reputation, it becomes important to the company, to investors and to other stakeholders. However, some studies examine the relationship between reputation and performance in the opposite direction, that is, they conclude that a company's financial soundness can generate good reputation (Dowling, 2006).
Several studies have proved the existence of relationship between reputation and performance (Brown and Perry, 1994). Carmeli and Tishler (2005) stated that corporate reputation affects the performance of organizations. The authors examined the following measures of performance: growth, profitability, financial soundness, market share and future sales' estimates, through the opinions of executives of the Kibbutz companies.
There are two approaches that allow to explore the effect of corporate reputation on the economic-financial performance of organizations. One of them considers financial measures, achieved through accounting indicators and historical returns. The other approach is based on the performance appraisal of the shares traded in stock exchanges. The second approach must prevail over the first, since the valuation of the shares is directly related to market perception ( from stakeholders) about the reputation of a certain company, which explains the difference between the book value and the market value of organizations nowadays (Lev, 2005;Gök and Özkaya, 2011;Perez and Famá, 2006).
Even if several authors have identified a positive and direct relationship between corporate reputation and performancethus justifying the investment strategies in this intangible resource -Gök and Özkaya (2011) reached different results. In investigating a sample of reputable companies (most admired) in an emerging market (Turkey), they concluded that investing in corporate image and reputation did not assure a good performance in the capital market, that is, it did not result in share valuation.
In summary, while some studies argue that a good corporate reputation can lead to superior performance (Brown and Perry, 1994;Carmeli and Tishler, 2005), others have pointed out that the relationship is reverse; in other words, a superior performance promotes a good reputation (Dowling, 2006). Other findings also showed the presence of weak or nonexistent relationships between these variables (Gök and Özkaya, 2011). The lack of convergence about the relationship between corporate reputation and performance shows the need for further studies in this research area.
Finally, although there are two approaches that allow us to explore the effect of corporate reputation on organizational performance (use of accounting indicators and historical returns or analysis of share valuation), we believe that the adoption of market indicators focusing on the value of companies' shares is the most appropriate approach, since these indicators include the value of intangible resources.

Closing Remarks
This study discussed the different approaches of the corporate reputation construct, in order to identify a comprehensive definition that can be operationalized for measurement purposes. In this sense, studies that address the relationship between corporate reputation and organizational performance were analyzed, along with the attributes of national and international corporate reputation ratings, by examining the scientific production related to the subject.
The theoretical discussion on the RBV, intangible resources and corporate reputation supported the choice of Barnett et al.'s (2006) definition of the reputation construct, who determined corporate reputation as the collective judgment of an organization by observers, based on financial, social and environmental assessments made over time. By adopting this definition, we could identify which elements should be present in the evaluation of corporate reputation: primary data, resulting from the collective judgment by stakeholders, and evaluations under different organizational perspectives (financial, social and environmental), conducted over time (longitudinal).
As for the different national and international reputation ratings, we found that the FMAC scale and the RQ have been used more frequently. In Brazil, the ratings published by Exame and Carta Capital magazines have achieved a higher recognition. According to the literature, the choice of methodology for the evaluation of corporate reputation must take into account: the rating context; changes in the ratings over time; comparison of competitors' ratings in the same industry; coverage of the publication and its readers; and the contrast between different methodologies (Fombrun, 2007).
This study allowed to advance the understanding of the reputation construct measurement, considering the adopted definition and the discussion of the attributes of the main ratings on corporate reputation -FMAC, RQ and Corporate Personality Scalewhich resulted in the selection of elements that should be present in the construct measurement: the collective judgment by a representative part of the organization's stakeholders: internal (executives and employees), suppliers, customers and the financial market (market analysts); the use of different organizational dimensions/perspectives (financial, social and environmental) in the assessment; systemic (longitudinal) evaluations of corporate reputation; the use of theoretical assumptions in building the evaluation scale; and the understanding that stakeholders may have different perceptions about the reputation of organizations.
In addition, we sought to improve the understanding of the relationship between corporate reputation and performance, given that reputation is an intangible resource that drives organizational performance. Literature indicates that a good corporate reputation can affect organizational performance (Brown and Perry, 1994;Carmeli and Tishler, 2005), and the inverse relationship is also true (Dowling, 2006). Other studies have not identified a relationship between these variables (Gök and Özkaya, 2011). These results reveal that the research field lacks studies that explore the causal relation between corporate reputation and organizational performance.
In short, this research has improved the discussion on corporate reputation in different domains. First, it shows that the research field has many definitions that cannot be used interchangeably (Walker, 2010). It indicated how the reputation construct should be operationalized for measurement purposes, from the definition by Barnett et al. (2006) and the analysis of the attributes of the main methodologies for corporate reputation assessment. Finally, it presented a reflection on the relationship between corporate reputation and performance, showing that it is not a settled topic in the academy, both with regard to the influential element (reputation affects performance or performance affects reputation), and to the type of metrics that should be used to assess the influence of corporate reputation on organizational performance.

Recommendations for future studies
Intangible resources are recognized as drivers of organizational performance, but there are limitations regarding the value of these elements and the way they affect organizational performance. As corporate reputation is one of the main intangible assets, it is important to understand how it contributes to reach a superior performance, thus encouraging studies on the subject.

Corporate reputation
Corporate reputation embraces a complex concept, with a diversity of definitions in the literature. This variety of concepts makes it difficult to adopt one definition and one method to measure the construct. Hence, applied studies that intend to assist in the operationalization of the corporate reputation construct will contribute to the advancement of this research area.
