Sectoral heterogeneity has been shown to affect country-level welfare gains from trade that can be calculated by sector-specific trade elasticities and home expenditure shares. However, empirical analyses of multi-sector models are restricted to a limited number of countries and sectors, mostly...

This paper develops an approach to measuring the intensity of competition in international markets. The method measures the degree of "outside" competition faced by exporters located in one source country from firms located outside the source country. We use the elasticity of price and quantity...

This paper evaluates the bias which may occur when trade elasticities are estimated using data on aggregate trade, instead of using data on bilateral trade. The exercise is done on the case of Macedonia. Elasticities obtained from aggregate-trade data, using the Autoregressive Distributed Lag...

Do tariffs inhibit trade flows by limiting the entry of exporting firms ('extensive margin') or by restricting the average volume exported by each firm ('intensive margin')? Using a gravity equation approach, we analyze how the decrease in tariffs promoted during the 1990s by the Uruguay Round...

Correct estimates of import demand elasticities are essential for measuring the gains from trade and predicting the impact of trade policies. We show that estimates of import demand elasticities hinge critically on whether they are derived using trade quantities or trade values, and this...

During the past decade China has emerged as South Africa's largest trade partner. In an effort to understand this important and remarkable trend, we estimate South Africa's import demand function with China over the period 1993-2012. Specifying an error-correction model, we use the bounds...

Brazil, like other natural resource-exporting countries, has benefited from a sharp increase in commodity prices over the last few years. To investigate the possible impact of terms-of-trade gains on the real economy, this paper estimates normalised quadratic input demand and output supply...

Correct estimates of import demand elasticities are essential for measuring the gains from trade and predicting the impact of trade policies. We show that estimates of import demand elasticities hinge critically on whether they are derived using trade quantities or trade values, and this...

This paper finds that U.S. consumer prices fell substantially due to increased trade with China. With comprehensive price micro-data and two complementary identification strategies, we estimate that a 1pp increase in import penetration from China causes a 1.91% decline in consumer prices. This...

Singapore is one of the world's most open economies, with the size of its trade reaching about 350 percent of its GDP. With the rise of highly diversified cross-border production networks, Singapore has come to play an integral role in the global supply chain with heavy reliance on foreign...
