In a multi-commodity framework with absence of wealth effects, we prove the existence of equilibrium for Cournot oligopoly, and that the concept is completely non-ambiguous. We also obtain a uniquely defined endogenous inverse demand function, depending only on the competitive sector.

Developing a dynamic SME sector is essential for countries transforming their centrally planned economy into a market oriented one. New firm formation is the major driver of this transition. Obviously, entrepreneurial energy is a necessary condition for new firm formation. This paper uses 2004...

For Bertrand duopoly with linear costs, we establish via a single (counter-)example that: (i) A new monotone transformation of the firms' profit functions may lead to the supermodularity of transformed profits when the standard log and identity transformations both fail to do so, and (ii)...

Arguing that entrepreneurial exit is an indicator of accumulated entrepreneurial human capital (like ability and experience) we investigate whether such an exit in the recent past positively relates to posterior engagement in various stages of the entrepreneurial process (i.e. potential,...

When consumers differ in their attitude towards risk, price competition between products of uncertain characteristics may be analyzed using address-models of product differentiation. These models provide a natural set-up for analyzing industries in which products of different reliability may...

We investigate which countries have the highest potential to achieve entrepreneurial progress. This progress is defined using an entrepreneurial ladder with five successive steps: “never thought about starting a business”, “thinking about starting a business”, “taking steps to start a...

In this article, the process of the entrepreneurial decision is decomposed in seven engagement levels ranging from "never thought about starting a business" to "gave up," "thinking about it," "taking steps for starting up," "having a young business," "having an older business," and "no longer...

This note relates to Topkis (1995). We establish via counterexample that:(i) A new monotone transformation of the firms' profit functions may lead to cardinal complementarity when the standard log and identity transformations both fail, and (ii) Topkis's notion of critical sufficient condition...
