A model of the distribution of home-ownership in a city is developed. Heterogeneous houses are built by a competitive development industry and either rented competitively or sold through directed search to households which differ in wealth and sort over housing types. In the absence of both...

The effects of households' indebtedness on their house-selling decisions are studied in a dynamic equilibrium model with search in the housing market and defaultable long-term mortgages. In equilibrium, both sellers' asking prices and time-to-sell increase with the relative size of their...

Strategic interaction among oligopolistic innovators and its implications for economic growth are examined in two dynamic computable general equilibrium models. In each environment, technologies for producing a final good are such that the profits of any intermediate good producer depend on the...

Relationships between country size (measured by both population and aggregate GDP) and standard of living (measured by per capita GDP) and the volatilities of aggregate output, consumption, and investment are investigated for a sample of 56 countries. Both characteristics are shown to be...

The effects of entry and exit by monopolistically competitive intermediate goods producers on equilibrium business cycles are analyzed in the presence of internal returns to scale and external returns to specialization. In the environment studied, market power and endogenous entry and exit, in...

Using Kalman filtering and dynamic factor analysis, we decompose fluctuations in real aggregate output, consumption, and investment for the G7 countries into factors that are (i) common across all countries and aggregates, (ii) common across aggregates within a country, and (iii) specific to...

Dynamic factor analysis and Kalman filtering are used to construct a measure of common economic activity for the G7 countries. Common movements are important in productivity, but account for a substantially smaller share of movements in investment, and virtually none of the variation in the...

Many international macroeconomic models link the real exchange rate to a ratio of marginal utilities. We examine this link empirically, allowing the marginal utility of consumption to depend on government expenditure, real money balances, or external habit. We also consider two environments with...

Euro-interest rates are well-known to be persistent, as are their differentials across countries for a given maturity. The international CCAPM implies that the rates are persistent because forecasts of national consumption growth or inflation are persistent too. We examine this prediction for a...

We develop and estimate a search model in which identical consumers trade with price-setting firms that differ in productivity. In the model, equilibrium distributions of both prices and markups are non-degenerate and continuous with a firm's price decreasing as its productivity increases....
