The aim of this paper is to account for both the short-run uctuations and thevery-long run transformations induced by technological change in analysing long-rungrowth patterns. The paper investigates the possible imprint left by short-run uctuationson the long run dynamics by aecting the...

Why is GDP so much more volatile in poor countries than in rich ones? To answer this question, we propose a theory of technological diversification. Production makes use of different input varieties, which are subject to imperfectly correlated shocks. As in endogenous growth models,...

A two-sector real business cycle model, estimated with postwar U.S. data, identifies shocks to the levels and growth rates of total factor productivity in distinct consumption- and investmentgoods- producing technologies. This model attributes most of the productivity slowdown of the 1970s to...

The aim of this paper is to account for both the short-run fluctuations and the very-long run transformations induced by technological change in analysing long-run growth patterns. The paper investigates the possible imprint left by short-run fluctuations on the long run dynamics by affecting...

This paper develops a growth model with land, housing services, and other goods that is capable of explaining a substantial portion of the movements in housing prices over the past forty years. Under certainty, the model exhibits a balanced aggregate growth, but with underlying sectoral change....

A new technology is a bold new combination of production factors that potentially yields a higher level of total factor productivity. The optimal combination of input factors is unknown when an innovation is pursued. A larger targeted innovation may require a greater change in the optimal...

This paper investigates a variety of objectives that are commonly used to motivate government fiscal action. These include welfare maximization, stabilization and growth maximization. The policies are compared on the basis of their implications for welfare, volatility and growth. We show that...

For US postwar data, the paper explains central consumption, labor, investment and output correlations and volatilities along with output growth persistence by including a human capital investment sector and a variable physical capital utilization rate. Strong internal "amplication" results from...

We study how advances in labor-substituting (automation) technologies affect production networks. Labor-substituting advances lower the wages of substitutable workers relative to non-substitutable workers, affecting employment in the entire economy, well beyond the production chains adopting the...

This paper examines how the degree of interbank competition affects real economic growth, growth patterns, and consumer welfare using a dynamical systems approach. Risk averse agents insure against idiosyncratic risk via deposit contracts that maximize bank profits. These contracts are derived...
