Immigrants can foster host-country trade flows by using their information network. However, the heterogeneity in skill level and increasing diversification in terms of both origin and destination of the immigrants have added complexity to this issue. This paper examines the causal linkage...

We carry out an indirect inference test of two versions of a computable general equilibrium (CGE) model of world trade. One of these, the ‘classical’ model,is well-known as the Heckscher-Ohlin-Samuelson model of world trade, in which countries trade homogeneous products in world markets and...

The economic effects of a pandemic crucially depend on the extend to which countries are connected in global production networks. In this paper we incorporate production barriers induced by COVID-19 shock into a Ricardian model with sectoral linkages, trade in intermediate goods and sectoral...

The 1990s produced a large literature on foreign trade and the environment, including both theoretical and empirical contributions. The paper surveys this literature. It starts by looking at the traditional Heckscher–Ohlin type models of international trade and then moves to noncompetitive...

Although economists have long been aware of Jensen's inequality, many econometric applications have neglected an important implication of it: the standard practice of interpreting the parameters of log-linearized models estimated by ordinary least squares as elasticities can be highly misleading...

Although economists have long been aware of Jensen's inequality, many econometric applications have neglected an important implication of it: estimating economic relationships in logarithms can lead to significant biases in the presence of heteroskedasticity. This paper explains why this problem...

What is the effect of nominal exchange rate variability on trade? I argue that the methods conventionally used to answer this perennial question are plagued by a variety of sources of systematic bias. I propose a novel approach that simultaneously addresses all of these biases, and present new...

We review a recent body of theoretical work that aims to put numbers on the consequences of globalization. A unifying theme of our survey is methodological. We rely on gravity models and demonstrate how they can be used for counterfactual analysis. We highlight how various economic...

In this paper we explore the role that demand uncertainty plays for the offshoring decision, and the role that offshoring plays for domestic volatility of employment. Offshoring is modeled as in Antràs & Helpman (2004), but we assume complete contracts. Firms are heterogeneous as in Melitz...
