We analyze a successive vertical Cournot oligopoly model with homogeneous intermediate and final goods. Under restricted entry in both upstream and downstream markets, the input price continuously falls on a sequential merger path. Partial input foreclosure never occurs. However, when there is...

When a vertically integrated firm competes against non integrated rivals in the input and the final-good markets, the layman's belief is that, when the non-integrated downstream firms purchase part of their input from the up- stream division of the integrated firm, the downstream division will...

A well-known result in oligopoly theory regarding one-tier industries is that the equilibrium mark-up and the Lerner index decreases with the number of firms. In other words, market power is diminished when more firms are present in the market. In the present paper, we consider a two-tier...

Based on a traditional approach to the behavior of a bank which lends both private and public sector, and utilizing a typical expression for public debt accumulation, this paper concludes that the optimality of the number and size of banks depends heavily on the course of the public debt,...

In this article we discuss the salient features of the classical and neoclassical theories of competition and we test their fundamental propositions using data from Greek manufacturing industries. The cross section data of 3-digit (total 91) industries of the three (pooled together) census years...

The long-run evolution of per-capita income exhibits a structural break often associated with the Industrial Revolution. We follow Mokyr (2002) and embed the idea that this structural break reflects a regime switch in the evolution of technological knowledge into a dynamic framework, using Airy...

Most real world emission permit schemes are in effect hybrid instruments that feature both quantity and price controls. While the effects of price bounds are well understood for issues such as uncertain abatement costs it has not been investigated how such bounds affect time-consistency of...

This paper develops a new open-economy endogenous growth model where technology diffusion allows for a stable and non-degenerate world income distribution. In accordance with the empirical literature, I find that country characteristics such as the social infrastructure, the degree of openness,...

An analytical framework is developed to study the repercussions between endogenous capital- and labor-saving technical change and population aging. Following an intuition often attributed to Hicks (1932), I ask whether and how population aging aff ects the relative scarcity of factors of...
