This paper uses data across 365 corridors to document time and country variation in remittance fees and explore factors predicting variation in remittance fees. We document a general reduction in such fees over the past decade although the goal of fees below 3 percent has not been met yet in many corridors. We identify both cost- and risk-based constraints and market structure as barriers to lower remittance fees. Higher transaction costs as result of a more rural population in the sending country and lower scale are associated with higher remittance fees. However, lower risks due to the stability of fixed exchange rates and Internet rather than cash payment are associated with lower remittance fees. Finally, remittance corridors dominated by banks and few players are characterized by higher fees.
In the cross section of countries, there is a strong positive correlation between trade and income, and a negative relationship between trade and inequality. Does this reflect a causal relationship? We adopt the Frankel and Romer (1999) identification strategy, and exploit countries' exogenous geographic characteristics to estimate the causal effect of trade on income and inequality. Our cross-country estimates for trade's impact on real income are consistently positive and significant over time. At the same time, we do not find any statistical evidence that more trade increases aggregate measures of income inequality. Heeding previous concerns in the literature (e.g. Rodriguez and Rodrik, 2001; Rodrik, Subramanian and Trebbi, 2004), we carefully analyze the validity of our geography-based instrument, and confirm that the IV estimates for the impact of trade are not driven by other direct or indirect effects of geography through non-trade channels.
