We study the behavior of firms in an imperfectly competitive environment in which firms influence the evolution of the stock of capital equipment. Our model enables us, using analytical characterizations, to show the effect of key ingredients of dynamic competition on firm strategies and industry dynamics in addition to the usual static interaction. These effects are the static market externality (implicit in the static Cournot Equilibrium) as well as the dynamic market externality due to the effect on the market outputs of a capital stock and a dynamic externality that stems from the competition between firms for the capital stock. These strategic elements justify our conclusions, based on the study of four market structures, for the link between industrial organization and industry growth [less ▲]

We suggest a simple survey method for obtaining direct subjective estimates of equivalence scales, also appropriate for testing whether equivalence scales depend on reference-household income. We implement our approach in two countries, Germany and France. In both countries independence of base is rejected. In particular, we find that equivalence scales depend negatively on reference income, an indication of increasing economies of scale in household consumption as living standards go up. Our estimation method is non-parametric, and it allows us to test generalized equivalence-scale exactness, which is not rejected in any of our samples. [less ▲]

R\&D Investment, Market Structure, and Industry Growth

We study how alternative market structures influence market supply and R\&D investment decisions of firms operating in dynamic imperfectly competitive environments. Firms can reduce their future production cost through R\&D investment today, which is the engine of endogenous industry growth. Our framework enables us to identify key strategic ingredients in firms dynamic competitive behavior through analytical characterizations. These ingredients are a static market externality, stemming from the standard oligopolistic Cournot competition, a dynamic externality that arises due to knowledge spillovers, and a dynamic market externality that comes from the interaction of knowledge spillovers with future market oligopolistic competition that firms internalize while making decisions. We isolate the impact of each strategic ingredient by comparing four alternative market structures. [less ▲]

How do national minimum wages affect global economic growth? We address this question in a two-country endogenous growth model with capital mobility that emphasizes a link between wages, savings and growth. We identify the conditions on technology and national preferences that determine whether national minimum wages are a stimulus or an obstacle to growth. Technology matters because it determines the functional distribution of global income as well as output effects associated with the emergence of national unemployment due to minimum wages. Interestingly, differences in national savings propensities do not only affect the strength of the growth effect associated with minimum wages but may even determine its direction. [less ▲]

Wage Growth, Productivity Growth, and the Evolution of Employment

This Paper studies the impact of wage growth on the evolution of employment in an intertemporal general-equilibrium model with endogenous productivity growth. For real wage growth above laissez-faire levels, we obtain steady-state equilibria in which productivity grows at the same rate as wages, the real interest rate is below the laissez-faire level, and so is the common growth rate of consumption, demand, and output. In these steady-state equilibria employment contracts at a constant rate equal to the difference between the growth rates of productivity and output. This contrasts with the view that equality of wage growth and productivity growth is a condition for constant employment. [less ▲]

The paper presents the basic assumptions of an intentionality theory-based view of emotions in the philosophy of mind and its implications for psychological research programs. Intentionalistic view conceives emotions as complex mental states with semantic content, especially as interconnected beliefs and desires. Particular types of emotions (e.g., anger, joy) are regarded as structures of beliefs and desires with abstract semantic contents. Different variants of one emotion type (e.g., anger about self, anger about others) are individuated according to their concrete semantic contents. Relations between emotions and other intentional phenomena are viewed as inferential relations. Relations between objective states of affairs and emotions are seen as representational relations. Advantages of this view are a more adequate conceptualization of emotional phenomena, options for an analysis of emotions differentiated by their objects, elaborations of cognitive and motivational theories of emotion, and a structural model of the causes and consequences of emotional responses to complex situations. These implications are evaluated with reference to heuristic gains and methodological requirements. [less ▲]
