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 ▲]

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 ▲]

Increasing marginal tax rates and making payments to the poor reduce inequality and introduce savings dis-incentives. Using a heterogeneous agent model with incomplete markets, we show that higher taxes (and transfers) decrease consumption inequality but also mean savings and mean consumption. This demonstrates the trade-off between equity and efficiency. These theoretical predictions are tested by exploiting differences in tax rates across US states. Using two surveys, the Consumer Expenditure Survey and the Current Population Survey, we show that the empirical evidence supports the theory, and that there is a comparatively small fall in efficiency for a given gain in equity associated with higher taxation.

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 ▲]
