The Pollution-Haven Hypothesis suggests that tight environmental standards reduce domestic producers' competitiveness and give rise to their relocating to countries with more lenient standards. This paper questions that relocation is always caused by reduced competitiveness at home. By using a...

Applying a newly developed CGE-model, we present scenarios for the future economic geography of Europe. The model divides the world into ten regions, five of which are European, and 14 industries, of which 12 are imperfectly competitive. With a complete input-output structure, the model captures...

Political motives, geography, and the uneven distribution of gains trumped the traditional efficiency gains across Africa's Regional Economic Communities (RECs). The small, sparsely populated, fragmented, and often isolated economies across Africa make a compelling case for these economies to...

We present an international trade model with multiproduct firms. Firms are heterogeneously endowed with two types of capabilities that jointly determine the trade-off within firms between managing a large portfolio of products and producing at low marginal cost. The model can explain many of the...

We develop a general equilibrium model of monopolistic competition with a traded and a non-traded sector. Using a broad class of homothetic preferences - that generate variable markups, display a simple behavior of their elasticity of substitution, and nest the ces as a limiting case - we show...

In the two-country Melitz (2003) model, unilateral trade liberalization is often cast as a reduction of iceberg transportation costs and wages are determined by a linear outside sector. We show that welfare results reverse when wages adjust and trade frictions are revenue-generating tariffs. --...

Increasing-returns-to-scale imperfect competition trade models predict a more than proportionate relationship between the larger country's share in world endowments and its share in producing firms: the so called home market effect (HME). While this result plays a key role in empirical testing,...

Recent trade theory in the Krugman (1980) tradition predicts that countries with larger market size enjoy higher levels of total factor productivity (TFP) - and equivalently of real per capita income or welfare - as a smaller fraction of spending on inputs is affected by trade costs. However, in...
