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 revisits the D-S (Dixit-Stiglitz) model. It’s a simple general monopolistic model with n monopolistic goods, and a numeraire good Labour ( w=1); aggregation for all goods in the economy. We have considered in our paper constant elasticity of substitution case(CES).On the supply...

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...

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.

Recent years have witnessed an enormous amount of reorganization of the corporate sector in the US and in Europe. This paper examines the role of market competition for this trend in corporate reorganization. We find that at intermediate levels of competition the CEO of the corporation decides...

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...
