This paper examines the evolution of a skew distribution of firm sizes from the viewpoint of the ?Bounds? approach to market structure. It confines attention to the role played by non-strategic factors (statistical independence, and cost side-effects). A model is proposed, which leads to a...

This paper examines integration decisions of successive duopolists. It is shown that qualitatively the same pattern of integration emerges whether there is Cournot or Bertrand competition in the input market. The degree of integration in the industry is increasing in the size of the downstream...

Countertrade - or reciprocal buying - is defined as a transaction involving (at least) a two-way transfer of goods, rather than a singular transfer of goods for money. The main objective of this paper is to explain the extensive use of countertrade both between countries and between firms within...

This paper is concerned with the determinants of car prices in four European countries: Belgium, France, Germany and the United Kingdom, over the period 1970-1985. The main focus of the study lies in explaining the levels of, and the changes in, the large price differentials observed across the...

We stablish the validity of higher order asymptotic expansions to the distribution of a version of the nonlinear semiparametric instrumental variable considered in Newey (1990) as well as to the distribution of a Wald statistic derived from it. We emply local polynomial smoothing with variable...

We model differences among agents in their ability to recognise temporal patterns of prices. Using the concept of DeBruijin sequences in two dynamic models of markets, we demonstrate the existence of equilibria in which prices fluctuate in a pattern that is independent of the fundamentals and...

We consider a neo-classical model of optimal economic growth with c.r.r.a. utility in which the traditional deterministic trends representing population growth, technological progress, depreciation and impatience are replaced by Brownian motions with drift. When transformed to 'intensive' units,...

In the theory of judgment aggregation on logically connected propositions, an important question remains open: Which aggregation rules are manipulable and which are strategy-proof? We define manipulability and strategy-proofness in judgment aggregation, characterize all strategy-proof...

This paper explores the logic of amp;scal restraints in a political agency model with both moral hazard and adverse selection. The role of the political process is both to discipline incumbents who may act against the public interest and to sort in those politicians who are most likely act in...

This paper investigates the relationship between growth and inequality from a demographicpoint of view. In an extended model of the accidental bequest with endogenous fertility, weanalyze the effects of a decrease in the old-age mortality rate on the equilibrium growth rateas well as on the...
