In an economy where growth is determined by the interaction of R&D and learning-by-doing (LBD), changes of factors that stimulate either one of these activities affect growth differently than in an economy where growth is determined by either R&D or LBD alone. In particular, when firms...

The purpose of this paper is to describe recent financial innovation in the United States, outline its principal implications with regard to (1) the structure and behavior of financial markets and (2) the conduct of monetary policy, and speculate on the likely character of further innovation in...

Previous studies of disinflation work with models in which firms use time-dependent strategies, changing nominal prices at intervals of fixed length. These models may be criticized for failing to allow pricing behavior to adjust after a large shift in policy regime. Consequently, this paper...

There is pervasive evidence that individuals invest primarily in domestic assets and thus hold poorly diversified portfolios. Empirical studies suggest that informational asymmetries may play a role in explaining the bias towards domestic assets. In contrast, theoretical studies based on...

The commercial banking system in this country has undergone an unparalleled consolidation movement since the mid-1960's.

For industrial countries in the post-war period, the price level and the money stock have displayed little tendency to revert to given growth paths. Indeed, this stylized fact is frequently referred to by monetarist critics of central banks, who point out that periods of temporarily high or low...

A requirement for the study of macroeconomic behavior in the early 1980s is an understanding of the monetary policy pursued by the Federal Reserve and of the way this policy was implemented. In an attempt to fulfill this requirement, the formulation and implementation of monetary policy are...

In the classical macroeconomic models constructed by Lucas (1972, 1975) and Barro (1976), monetary aggregates are assumed to be generated by a logarithmic random walk. This specification implies that all monetary growth is (a) unanticipated and (b) permanent.

This paper studies the effects of fiscal policies--depicted as stochastic changes in government spending and distortionary tax rates--when the government is constrained from using lump sum taxes for achieving intertemporal budget balance. The ratio of debt to gnp, therefore, has consequences for...

This paper studies how the arrival of information affects welfare in a general equilibrium exchange economy with incomplete and differential information. It considers a setup in which agents differ in their attitudes toward risk. This introduces gains from trade. In equilibrium, the information...
