The attempts to explain the high and sticky credit card rates have given rise to a vast literature on credit card markets. This paper endeavors to explain the rates in the Turkish market using measures of non-price competition. In this market, issuers compete monopolistically by differentiating...

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...

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...

In diesem Beitrag zeigen wir, dass theoretische und technologische Aussagensysteme zwei eigenständige Forschungszweige darstellen und damit die Notwendigkeit erwächst, eine eigene Methodologie technologischer Aussagensysteme zu entwerfen. Wir stellen erste Ansatzpunkte vor, wie eine solche...

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...
