This paper analyzes the effect of commodity price fluctuations on a commodity-exporting economy. Using Chilean and international copper market data, I find that positive copper price changes resulting from copper-specific demand shocks generate a broad GDP expansion, with no visible decline in...

This study applies the Quadratic Almost Ideal Demand System (QUAIDS) to the Asian Development Bank's Multi-Region Input-Output (MRIO) dataset to estimate global demand and supply elasticities across intermediate vs. final, and domestic vs. foreign sectors. Using pooled data from 2021-2023,...

This paper deepens the analysis of the income elasticities of import and export demand in relation to the real exchange rate (RER) within a balance of payments constrained growth framework. It identifies how the RER can affect these elasticities and explores the resulting implications. A key...

This paper investigates the role played by firms’ managerial skills in the heterogeneous reaction of exporters to common exogenous changes in their international competitiveness (here captured by changes in the real exchange rate). Relying on a simple theoretical framework, we show that firms...

This paper re-examines foreign direct investment motives in the 'FDI gravity' model (Kleinert and Toubal, 2010), focusing on the role of distance. More precisely, we investigate whether aggregate and pooled gravity models for FDI obscure relevant heterogeneities across sectors. This is possible...

This paper investigates the trade elasticity, a key parameter in international economics, and examines biases in its estimation arising from dynamic treatment effects and staggered adoption. Leveraging the 2018 US trade war tariffs as a natural experiment, I apply a local projections...

This study seeks to test the validity of the Marshall-Lerner (M-L) condition between Egypt and BRICS countries (five countries: Brazil, Russia, India, China, and South Africa) to determine which industries will benefit from depreciation in the long run by employing the import and export models...

This paper reveals significant errors in a key variable in international trade: tariff rates. The issues arise from incomplete reporting, leading to measurement error from false interpolation by the data provider, the World Integrated Trade Solution (WITS), and selection bias from dropping...

This paper uses a new dataset on the universe of Canadian imports and tariffs between 1924 and 1936, disaggregated into 1697 goods originating in 112 countries, to analyse the impact on Canadian imports of interwar Canadian trade policy, including the 1932 Ottawa trade agreements. Rather than...

During the U.S.-China trade war, the U.S. punitive tariffs were almost entirely borne by U.S. importers. In contrast, only 68% of China's retaliatory tariffs were paid by Chinese importers. The puzzling difference between the U.S. and China is mainly driven by their different import structures...

We measure gains from trade in multi-sector economies with non-homothetic preferences where changes in trade costs generate reallocation of expenditure across sectors. We show how to measure the trade elasticity and how it relates to welfare. In this environment, the trade elasticity now varies...

Armington's insight that imports and domestically produced goods were imperfect substitutes has unleashed extensive estimates of the associated trade elasticity, primarily for developed countries. This notion of product differentiation, which extends symmetrically to exports and domestic goods,...

Many studies use tariffs to measure changes in trade policy. This paper shows that standard sources for tariffs suffer from substantial measurement error due to misreporting and the resulting false imputation: Countries fail to report tariffs every year and missing data are more prevalent for...

Purpose This study estimated total import demand elasticities concerning income, import prices and domestic prices. A high propensity to import constitutes a significant obstacle to economic growth in Mexico since the benefits of increased exports or any other aggregate demand expansion leak to...

Bilateral trade relationships between countries vary across products. Such heterogeneity poses challenges when assessing the economic impacts of trade agreements. This paper estimates bilateral trade elasticities at the product level and explores these impacts using a hypothetical no-deal Brexit...
