This paper proposes a simple approach to analyzing pro¯t dynam- ics which allows for time-varying persistence of pro¯ts. The time se- ries model is a simple autoregressive process where the dynamics of the persistence parameter follow an autoregressive or random walk pro- cess. Using the...

Recent studies in high-income industrialized countries have shown that equivalence scales are income-dependent. We investigate whether this dependence also holds in poorer, services oriented countries, by considering the example of Cyprus. We also examine whether household economies of scale and...

This paper addresses the question of what it takes to obtain a well-de?ned extensive form game. Without relying on simplifying ?niteness or discreteness assumptions, we characterize the class of game trees for which (a) extensive forms can be de?ned and (b) all pure strategy combinations induce...

This paper shows that “wasteful” litigation about intellectual property may be welfare enhancing. The aim of an intellectual property protection system is to solve the trade-off between exante innovation incentive and ex-post monopoly welfare loss. The litigation about intellectual property...

In an evolutionary sender–receiver game that describes how signals become associated with objects (Hurford, 1989; Nowak and Krakauer, 1999), the set of evolutionarily stable states coincides with the set of strict Nash strategies—and a language is a strict Nash strategy if and only if it links...

We study the determinants of voting outcomes on the provision of public consumption through marginal income taxes in the context of the simple linear growth model. We provide analytical results on how the dynamic politicoeconomic equilibrium maps the economic fundamentals to policies and...

We analyze imperfect competition in dynamic environments where firms use rivalrous but nonexcludable industry-specific capital that is provided exogenously. Capital depreciation depends on utilization, so firms influence the evolution of the capital equipment through more or less intensive...

This paper reassesses the impact of in°ation on long-term growth for a panel of 14 EU countries. While previous research focuses on a linear nexus or allows for a piecewise linear relationship with one single threshold, we take account of a more complex relationship. We use a theoretical...

Dynamic competitive models of industry evolution suggest that firm profit will be more volatile and turnover will be lower in industries with higher sunk costs. These implications are consistent with empirical observation.

Article VI of the GATT allows counter measures of goods are sold on a foreign market at a price below average production plus transportation costs. The present article analyzes Article VI based on a simple game theoretic model with two countries and economies of scale in the production of one...
