export quality, financial constraints, financial development, financial institutions, financial markets | NGUYEN Svirydzenka (2016), it is assumed that a country with a higher level of financial development also has a high degree of financial access, as well as depth, efficiency and lower costs of financial transactions; this means that a higher level of financial development may stimulate firms to produce higher quality products through investment and innovation. Figure 1 depicts some primary observations on financial development and export quality. It seems that there is a positive relationship between financial development and export quality in all three income groups; i.e., low-and lower-middle-income economies (LMEs), upper-middle-income economies (UMEs) and high-income economies (HIEs).This study endeavours to shed some light on the influence of financial development on export quality at the global level. The first contribution of this study is that the quality sorting model (a microeconomic model) of Fan et al. (2015) is linked to the macroeconomic context through the impact of financial development on export quality. Notably, in the study, financial development is proxied by (a) the overall financial development index; (b) its two sub-indices (financial institutions index and financial markets index); and (c) three dimensions of each sub-index indicating depth, access ability and efficiency (Svirydzenka, 2016). Regarding the groups of different economies, the study collects an available data set of 49 LMEs, 31 UMEs and 48 HIEs. Three different groups are formed to avoid correlation between income level and export quality, as documented in Krishna and Maloney (2011). Based on the previous literature, the study includes a set of control variables, namely export diversification, trade openness, FDI inflows, institutional quality and human capital accumulation. Given the availability of institutional quality from 2002, and export quality up to 2014, the 2002-14 period is a sound choice. Several econometric techniques for panel data are applied to check for causality and control for endogeneity, heteroscedasticity and cross-sectional dependence. A longer data period is also collected from 1980 to 2014, retaining only some main control variables for long-term estimations.The estimation results show robust findings. First, bidirectional causality between financial development and export quality is documented, including overall financial development, its two sub-indices and three dimensions of each sub-index. Second, the regressions for different estimators indicate a significant positive impact of overall financial development on export quality in all three groups of economies. Third, the two sub-indices of financial development and each of the three dimensions of the sub-indices are found to have positive effects on export quality in the three groups of economies, except for financial institution depth and access, which are not significant for UMEs. These results suggest that an increase in financial developmen...
