After some decades of relative oblivion, the interest in the optimality properties of monopolistic competition has recently re-emerged due to the availability of an appropriate and parsimonious framework to deal with firm heterogeneity. Within this framework we show that non-separable utility,...

The literature on research joint ventures (RJVs) has emphasized internalizing spillovers and cost-sharing as motives for RJV formation. In this paper we develop two additional explanations: product market complementarities and firm heterogeneity. We analyse a model of RJVs with asymmetric firms...

The purpose of this paper is to shed some light on why so many smaller-scale firms which have traditionally been classified as sub-optimal scale firms can exist. We suggest that by pursuing a strategy of compensating factor differentials, that is by remunerating and deploying factors of...

This paper sheds light on the questions, Why does knowledge spill over? and How does knowledge spill over? The answer to these questions lies in the incentives confronting scientists to appropriate the expected value of their knowledge considered in the context of their path-dependent career...

This paper studies the choice of organizational forms in a multi-task principal-agent model. We compare a functional organization in which the firm is organized into functional departments such as marketing and R&D to a product-based organization in which the firm is organized into product...

There is a tremendous diversity in the level and time-series pattern of the self-employment rate across countries. After documenting this fact with cross-section and time-series data on industrialized and lesser-developed countries, this paper presents and tests a series of hypotheses concerning...

The decision of how best to appropriate the value of new economic knowledge is reached by individuals within the context of the decision-making process embedded in the principal-agent model and applied to organizations. Because new economic knowledge is not only imperfect but also inherently...

Stochastic frontier production functions are estimated for Bulgarian (1993–5) and Romanian (1994–5) manufacturing industries using firm-level panel data. The technical efficiency of firms is found to vary significantly both within and across industrial sectors in each country. We find strong...

How many cartels are there? The answer is important in assessing the efficiency of competition policy. We present a Hidden Markov Model that answers the question, taking into account that often we do not know whether a cartel exists in an industry or not. Our model identifies key policy...

This paper examines the link between liquidity constraints and investment behaviour on the one hand, and firm size on the other for a large sample of German firms over the time period 1968-85. The results indicate that smaller firms tend to have investment functions which are more sensitive to...
