The paper first demonstrates that in a simple asymmetric n-country world with Cournot competition, constant returns and linear demand, free trade can reduce world welfare as well as total output and consumer surplus. We then derive precise conditions for free trade to raise a country's welfare,...

This paper develops a method to measure difficulties in market access over a large set of countries (both developing and developed) and industries, during the period 1980-2006. We use a micro-founded heterogeneous-consumers model to estimate the impact of national borders on global and regional...

We use Italian firm-level data to investigate the impact of trade openness on the distribution of firms across marginal cost levels. In so doing, we implement a procedure that allows us to control not only for the standard transmission bias identified in firm-level TFP regressions but also for...

This paper suggests a quantifiable multi-sector-multi-country economic model of goods and services production and consumption. It calibrates overall (variable and fixed) costs to market-specific sales by sector and decomposes these costs into observable and unobservable components. In an...

Much potential for trade liberalization exists in industries and markets with trade barriers that are prohibitive for all or many firms. In standard political economic theories of trade policy, observed prohibitive barriers must be globally optimal according to both individual and joint...

How does import protection affect export performance? In trade models with scale economies, import liberalization can reduce industry-level exports by cutting domestic production. We show that this export destruction mechanism reduced US export growth following the permanent normalization of...

We consider an international cartel whose members interact repeatedly in their own as well as in third-country segmented markets. Cartel discipline-an inverse measure of the degree of competition between firms-is endogenously determined by the cartel's incentive compatibility constraint (ICC),...

Audiovisual services such as music and movies in digital formats have gained substantial importance over the last decade. This paper analyses audiovisual services in a gravity model framework. In particular, we explore the role of virtual proximity -- a new proxy for cultural proximity based on...

The present paper examines trade liberalization driven by the coordination of product standards. For oligopolistic firms situated in separate markets that are initially sheltered by national standards, mutual recognition of standards implies entry and reduced profits at home paired with the...

In this paper, we measure market access between the United States, the EU, and Japan (the Triad), using the effect of national borders on trade patterns. We investigate overall and industry-level trends of bilateral trade openness and provide explanations for those using proxies for bilateral...
