Recent literature on the workhorse model of intra-industry trade has explored heterogeneous cost structures at the firm level. These approaches have proven to add realism and predictive power. This paper presents a new and simple heterogeneous-firms specification. We develop a symmetric...

This paper investigates how firms' demand uncertainty with capacity constraints and their productivity heterogeneity affect their making-or-buying organizational choices in a general equilibrium framework with incomplete contracts. It shows that a final-good producer may adopt integrating a part...

The link between regional integration and intra-industry trade (IIT) has been under scrutiny since it has been first suggested by the European integration process. However, the lack of reliable data and the difficulty to find a robust model for IIT made this relationship difficult to prove. This...

This paper examines the investment and welfare effects of a preferential trading area (PTA) on member and non-member countries when countries differ in their relative size. I numerically solve a three-country and two-good model to characterize equilibria pertaining to investment diverting and...

This study attempts to identify some characteristics of the relationship between journalists and politicians. The methodology of the research is based on the analysis of responses to interviews in depth applied to a sample of 50 print and audiovisual journalists from Bucharest, Suceava, Pitesti,...

This paper builds a two-country-two-sector trade model with a monopolistically competitive sector and non-homothetic preferences. It assumes the existence of two types of goods: necessities (which are homogeneous) and luxuries (which are differentiated) and heterogeneous labor. The implications...

The main purpose of this study is to illustrate, with a simple monopolistic competition trade model, how trade liberalization (i.e., a decline in trade costs) can affect domestic entrepreneurs' decisions between domestic brands and foreign brands, and thus the degree of foreign brand...

There is strong evidence that different income groups consume different bundles of goods. This evidence suggests that trade liberalization can affect welfare inequality within a country via changes in the relative prices of goods consumed by different income groups (the price effect). In this...

We extend the basic model of trade protection with special interest groups developed in Grossman and Helpman (1994) to include monopolistic competition with variable markups. We find the following results: (i) for sectors organized into lobbies the endogenous import tariff is always positive and...

In models of monopolistic competition with a single factor of production, imposition of tariff can lead (paradoxically) to a drop in the aggregate price index of the import competing sector. The present model first introduces an internationally mobile capital in such a set up. It is found that...
