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...

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...

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 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 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...

We propose a simple and flexible reduced-form econometric approach to estimate gravity models in the short and the long run. The theoretical lens for interpreting our methods amends the canonical Lucas-Prescott adjustment formulation to allow for time-interval-varying...

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 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...

We propose new methods to identify the full impact of country-specific characteristics on bilateral trade flows within the framework of ‘the new quantitative trade model.' We complement theory with a simple two-stage estimating procedure, and offer a proof of concept by quantifying the impact...

This study provides a decomposition of the WTO Global Trade Costs Index into five policy-relevant components: transport and travel costs; information and transaction costs; ICT connectedness; trade policy and regulatorydifferences; and governance quality. The WTO Global Trade CostsIndex is based...

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...

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...

The departure of Tony Thirlwall, a pioneer, renowned scholar, and a generous mentor, is a major loss to economics. This article reviews his main contributions to economics. The article focuses on his approach and method to economics and on his research output in the theory and empirics of growth...

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...
