Trade liberalization leads to long-run gains, but it can also involve costly short-run macroeconomic adjustment. The paper explores the relative importance of these effects within a dynamic general equilibrium model that captures key elements of both international trade and macroeconomic models....

This paper studies the macroeconomic impact of higher tariffs using a two-country DSGE model with endogenous trade and heterogeneous firms. The analysis consists of two scenarios. First, we assume that one country increases tariffs while the other does not. Second, both countries raise tariffs....

We study how the interaction between economic openness and competitive selection affects the effectiveness of employment (and entry) subsidisation. Within a twocountry heterogeneous-firms model with endogenous labour supply, we find that optimal employment subsidies are always positive even...

This paper studies the impact of trade reforms on the evolution of plant's productivity in Chile (1979-2000). The main contribution of the paper is to construct detailed measures of trade liberalization disentangling the impact of export and import oriented policies. We find evidence of a...

This paper develops an intra-industry model of trade with heterogeneous firms to investigate the impact of trade on the evolution of within firm productivity. The main contribution is to incorporate endogenous labor productivity gains. Heterogeneous firms have different incentives to invest in...

In this paper, we present a standard quality ladders endogenous growth model with one significant new assumption, that it takes time for firms to learn how to export. We show that this model without Melitz-type assumptions can account for all the evidence that the Melitz (2003) model was...

Trade economists traditionally study the effect of lower variable trade costs. While increasingly important politically, technical barriers to trade (TBTs) have received less attention. Viewing TBTs as fixed regulatory costs related to the entry into export markets, we use a model with...

WTO negotiations deal predominantly with bound - besides applied - tariff rates. But, how can reductions in tariffs ceilings, i.e. tariff rates that no exporter may ever actually be confronted with, generate market access? The answer to this question relates to the effects of tariff bindings on...

This paper develops a general equilibrium model of international trade that features selection across firms, products and countries. Firms' export decisions depend on a combination of firm “productivity” and firm-product-country “consumer tastes,' both of which are stochastic and unknown...
