Effects of Export Orientation, Exchange Rates and Leverage on Firm Productivity: Evidence from Pakistan

This article empirically scrutinizes the effect of exchange rate changes, exchange rate uncertainty and firm leverage on firm-level productivity growth. It also examines the differential effects of these variables, conditional on the levels of exports. Finally, it investigates whether a firm’s heterogeneity in terms of its share of exports in total sales matters in determining the response of a firm’s productivity growth to these variables. The empirical analysis is based on an unbalanced panel data set with annual observations of 222 exporting firms listed on the Pakistan Stock Exchange over the 2009–2017 period. We find that both exchange rate changes and exchange rate uncertainty have significant, negative effects on the firm’s productivity growth, and exporting further makes intense these effects. Yet, we show that export activities are positively related to firms’ productivity growth. We also reveal that there is a significant heterogeneity in the effects of exchange rate changes, its uncertainty and leverage, which is attributed to export intensity. Specifically, we observe that the effects are more prominent in firms that export more shares of their output to foreign markets.
