Workers' remittances sent to Latin America declined sharply as the COVID-19 pandemic spread in the first half of 2020, rebounding in the second half. This paper uses a gravity model to estimate the impact of containment and economic support measures, as well as travel restrictions, on...

This paper evaluates the performance of alternative estimation methods for multiplicative and log models with heteroskedasticity. Contrary to Santos Silva and Tenreyro (2006), the results of a simulation study indicate that the Pseudo Poisson Maximum Likelihood estimator (PPML) is not always the...

This paper uses the gravity model of trade to investigate the link between foreign aid and exports in recipient countries. Most of the theoretical work emphasizes the negative impact of aid on recipient countries' exports primarily due to exchange rate appreciation, disregarding possible...

This paper uses an augmented gravity model of trade to investigate the link between German development aid and sectoral exports from Germany to the aid recipient countries. The findings indicate that in the long run each dollar of German aid is associated with an average increase of 0.83 US...
