This paper explores the effects of innovation efficiency on technology gap and product diversity between a leading firm and its competitor. Our analysis shows some interesting results: when innovation efficiency is sufficiently large and increases, the leading firm may expand technology gap, and...

We stress some efficiency aspects of monopolistic competition justifying it on account of its tendency to innovate and the questionable excess capacity paradigm. Some further efficiency aspects revealed are product variety and transaction cost savings. We view the monopolistically competitive...

This paper investigates the relationship between various market imperfections and the skill premium. The model in this paper assumes perfectly competitive labor markets but distorted product and financial markets. The model predicts that the skill premium is positively correlated with market...

A structural model of entry and fiscal policy is presented. It shows that taxation of variable production costs can increase product prices, lower competition, and reduce the availability of new products in small markets. The model?s test is based on a unique nationwide fiscal experiment. We...

A structural model of entry and fiscal policy is presented. It shows that taxation of variable production costs can increase product prices, lower competition, and reduce the availability of new products in small markets. Existing theoretical models of entry and taxation either assume imperfect...

Collective dismissal costs are an important part of employment protection legislation (EPL) and make firms' exit more costly. We show in a model with step-by-step innovations that dismissal costs spur innovation if product markets are not too competitive: technologically more advanced firms...

This paper studies the impact of income inequality on the level of innovative activities in a model where innovations result in quality improvements. The market for quality goods is characterized by a natural oligopoly with three types of consumers - rich, middle class and poor. In general, we...
