This note studies the choice of tax structure in a majority voting model with tax competition. Regions may tax mobile capital or immobile labor. Individuals differ with respect to their relative endowments of labor and capital. Even though a lump sum tax is available, the equilibrium capital tax in a jurisdiction may be positive. In a symmetric equilibrium, this will be true if the median capit...

The Logit version of Quantal Response Equilibrium (QRE) predicts that equilibrium behavior in games will vary systematically with payoff magnitudes, if all other factors are held constant (including the Nash equilibria of the game). We explore this in the context of a set of asymmetric 2×2 games with unique totally mixed strategy equilibria. The data provide little support for the payoff magnit...

We model the idea that when consumers search for products, they first visit the firms which advertise more, or the firms whose advertising is more salient. Equilibrium prices and advertising efforts are increasing in consumer search costs. By contrast, equilibrium profits are nonmonotonic in search costs so firms are not necessarily better off if search costs rise. In our model, firms are engag...

Cointegration analysis has led to equilibrium-correction econometric systems being ubiquitous. But in a non-stationary world subject to structural breaks, where model and mechanism differ, equilibrium-correction models are a risky device from which to forecast. Equilibrium shifts entail systematic forecast failure, as forecasts will tend to move in the opposite direction to data. We explain the...

This article adds technology choice to a free-entry Cournot model with linear demand and constant marginal costs. Firms can choose from a discrete set of technologies. This simple framework yields non-existence of equilibrium, existence of multiple equilibria and equilibria in which ex-ante identical ̄rms choose di®erent technologies as possible outcomes. I provide a full characterization of th...

This paper develops a dynamic, stochastic, general-equilibrium (DSGE) model for the Canadian economy and evaluates the real effects of monetary policy shocks. To generate high and persistent real effects, the model combines nominal frictions in the form of costly price adjustment with real rigidities modelled as convex costs of adjusting capital and employment. The structural parameters identif...

We prove existence of an Arrow–Debreu equilibrium when agents’ preferences exhibit local substitution in the sense of Hindy, Huang, and Kreps (1992). Efficient allocations and supporting price functionals are identified and characterized. Under Hindy–Huang–Kreps preferences, equilibrium price processes are semimartingales for arbitrary endowments, but in general, they do not belong to the space...

Search Frictions on Product and Labor Markets: Money in the Matching Function This paper builds a macroeconomic model of equilibrium unemployment in which firms persistently face difficulties in selling their production and this affects their decisions to create jobs. Due to search-frictions on the product market, equilibrium unemployment is a U-shaped function of the ratio of total demand to t...

We examine the relationship between the equilibrium number of the firms entering the market and socially efficient one. Salop (1979) investigates a mill pricing model and shows that the former is larger than the latter (excess entry theorem). We find that, in contrast to Salop (1979), the equilibrium number of the firms can be either larger or smaller than the efficient one. If the entry cost i...

Extending Barro (1999) and Luttmer & Mariotti (2003), we introduce a new model of time preferences: the instantaneous-gratification model. This model applies tractably to a much wider range of settings than existing models. It applies to complete and incomplete-market settings and it works with generic utility functions. It works in settings with linear policy rules and in settings in which equ...
