A growth model is developed in which finite-lived individuals invest in human capital, and investments have a positive external effect on the human capital of later cohorts. Heterogeneous labor is the only factor of production, and higher-quality labor produces higher-quality goods. Stationary...

A model is developed in which two complementary forms of investment contribute to growth--technology and skill acquisition, and growth takes two forms--TFP and variety growth. The rate of TFP growth depends more heavily on the parameters governing skill accumulation, while variety growth...

Technical change, even if it is limited in scope, can have employment, output, price and wage effects that ripple through the whole economy. This paper uses a flexible and tractable framework, with heterogeneous workers and technologies, and many tasks/goods, to analyze the general equilibrium...

This paper develops a model of investment decisions in which uncertainty about a one-time change in tax policy induces the firm to temporarily stop investing--to adopt a wait-and-see policy. After the uncertainty is resolved, the firm exploits the tabled projects, generating a temporary...

In a calibrated version of the model, transition paths after a policy change can display rapid growth, as in modern growth 'miracles.' In these economies policies that promote technology inflows are much more effective than subsidies to human capital accumulation in accelerating growth. A policy...

In this paper we analyze an aggregative general equilibrimi model in which the use of money is motivated by a cash-in-advance constraint, applied to purchases of a subset of consumption goods. The system is subject to both real and monetary shocks, which are economy-wide and observed by all. We...

Tournaments, reward structures based on rank order, are compared with individual contracts in a model with one risk-neutral principal and many risk-averse agents. Each agents' output is a stochastic function of his effort level plus an additive shock term that is common to all the agents. The...

Recent estimates of the potential growth effects of tax reform vary widely, ranging from zero (Lucas 1990) to eight percentage points (Jones, Manuelli, and Rossi 1993). Using an endogenous growth model, we assess which model features and parameter values are important for determining the...
