Abstract
This paper investigates empirically the effect of export diversification (i.e. both export product diversification and services export diversification) on financial openness, using a sample of 119 countries (including both developed and developing countries) over the period 1985–2014. Based on the Blundell and Bond’s two-step system Generalized Method of Moments, the analysis has revealed that both export product diversification and services export diversification influence positively financial openness. However, this outcome hides differentiated effects across countries in the full sample. Especially, countries with a very high real per capita income experience a positive effect of export concentration on financial openness, while for countries with a relatively lower per capita income, it is rather export diversification that drives positively financial openness. Interestingly, the effect of export diversification on financial openness depends on the size of external shocks that affect domestic economies, as well as countries’ economic growth performance. Overall, these findings add to the empirical literature on the effect of international trade on financial openness by showing that both export product diversification and services export diversification matter for financial openness.

Notes
Eichengreen and Gupta (2013) have argued that “traditional services” include trade and transport, tourism, financial services, and insurance. Modern services encompass communications, computer, information, and other related services. Sahoo and Dash (2017) has considered that traditional services covers transport and travel services, while modern services include transportability and tradability, financial services, insurance, business processing, and software services.
Kose et al. (2009) have provided a literature survey on the matter.
For example, Hausmann et al. (2007) have shown that as far as the relationship between export product structure and economic growth is concerned, what matters is the type of countries’ exports, including the sophisticated nature of those exports.
Countries are often confronted with external shocks such as commodity price shocks, export demand fluctuations, sudden surges or reversals of capital flows, natural disasters, and diseases. More than developed countries, developing ones experience a high persistence of shocks (e.g. Aguiar and Gopinath, 2007) and a higher frequency of such shocks (e.g. Álvarez et al., 2021; Dabla-Norris and Gündüz, 2014; Guillaumont, 2009).
Macbean and Nguyen (1980) have, nevertheless, provided a theoretical framework, which shows that in practice, commodity concentration might not be the main explanation of export earnings instability in developing countries.
Nevertheless, Grilli and Milesi-Ferreti (1995) have reported no significant effect of capital account liberalization and economic growth.
We have identified 18 countries in the full sample for which the values of the indicator of financial openness do not change at all or change once from one sub-period to another over the full period. The countries excluded are Algeria, Austria, Canada, China, Congo Rep, Denmark, Germany, Moldova, Namibia, Nepal, Netherlands, New Zealand, Panama, Singapore, Switzerland, Tajikistan, the UK, and the USA.
