The paper studies endogenous world balanced growth equilibria in which national learning productivity differentials govern relative per capita products. Learning productivities depend on the national share of world specialized-goods production, national and world scale, and familiarity with the...

We study the behavior of output, employment, consumption, and investment in Germany during the Great Depression of 1928-37. In this time period, real wages were countercyclical, and productivity and fiscal policy was procyclical. We use the neoclassical growth model to investigate how much these...

Whether technological progress raises or lowers aggregate employment in the short run has been the subject of much debate in recent years. Using a simple model of industry employment, we show that cross-industry differences of inventory holding costs, demand elasticities, and price rigidities...

Marshall made at least four contributions to the classical quantity theory. He endowed it with his Cambridge cash-balance money-supply-and-demand framework to explain how the nominal money supply relative to real money demand determines the price level. He combined it with the assumption of...

"We develop a quantitative theory of human capital with heterogeneous agents in order to assess the sources of cross-country income differences. The cross-sectional implications of the theory and U.S. data are used to restrict the parameters of human capital technology. We then assess the...
