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...

This paper develops a model of small open economy, with a differentiated goods sector and voluntary provisioning of public good. It is shown that trade policy can alter the quantity of public good provided in the equilibrium. Interestingly, tariffs may fail to protect, leading to a Metzler...

The article presents an analysis of the developer sector, which takes into account the ob-served functioning of the market. The analysis is based on the assumption that the housing developer, due to the asymmetry of information, is able to take advantage of a local monopoly and differentiate...

BARRIERS TO ENTRY: ABOLISHING THE BARRIERS TO UNDERSTANDING by Jan-Horst Keppler Professor of economics Université Paris – Dauphine, LEDa, and Université Paris I Panthéon-Sorbonne, PHARE Port.: (+33 6) 77 81 37 46; Email: jan.keppler@dauphine.fr. Abstract The concept of a barrier to entry...

This paper provides a DSGE model with firm entry. Simulations show that the model matches the synchronization of markups and entry observed in the data while at the same time reproducing empirically plausible moments for key macroeconomic variables. Sticky prices are essential for these results.

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...

This paper builds an evolutionary model of an industry where firms produce differentiated products. Firms have different average cost functions and different demand functions. Firms are assumed to be totally irrational in the sense that firms enter the industry regardless of the existence of...

In this paper we generalize the heterogeneous risk adverse agents model of diffusion of new products in a multi-firm, heterogeneous and interacting agents environment. We use a model of choice under uncertainty based on Bayesian theory. We discuss the possibility of product failures, the set of...
