We extend the basic Schumpeterian endogenous growth model by allowing incumbents to undertake innovations to improve their products, while entrants engage in more “radical” innovations to replace incumbents. Our model provides a tractable framework for the analysis of growth driven by both entry of new firms and productivity improvements by continuing firms. The model generates a non-degenerate...

When the Melitz model is implemented in practice, the industrial productivity distribution is often assumed to be of Pareto form. In this case, a fundamental relationship κ > σ − 1must hold to guarantee the convergence of the industrial average productivity, where κ is the concentration degree of the industrial productivity Pareto distribution and σ is the substitution elasticity across varieti...

The evidence that earnings rise with firm size and that human capital affects earnings based on labour market data are two of the most robust empirical findings in economics. In contrast the evidence for scale economies in firm data is very weak. The limited direct evidence of human capital on firm productivity suggests that human capital is indeed productive and that the magnitudes are consist...

T here is something in our national consciousness that looks fondly upon the small firm. This affection for small business is not entirely unwarranted. Small firms account for an important part of economic activity.1 A vast majority of all businesses in the United States are small; over 90 percent have fewer than 20 employees. Small firms accounted for between 40 and 50 percent of GNP and over ...

During the last years, supply chain performance measures have been in the spotlight of many authors. A large number of various performance measures have been utilised. In this paper a measure of efficiency is used as an indicator of performance in the vegetable supply chain. The study consists of two stages. The first stage involves Data Envelopment Analysis (DEA) which evaluates technical and ...

This paper presents a simple model of search and matching between consumers and firms. The firm size distribution has a Pareto-like right tail if the population of consumers grows at a positive rate and the mean rate at which incumbent firms gain customers is also positive. This happens in equilibrium when entry is sufficiently costly. As entry costs grow without bound, the size distribution ap...
