We develop a model of "intrinsic" cycles, driven by the decentralized behavior of entrepreneurs and firms making continuous, divisible improvements in their productivity. We show that when the introduction of productivity improvements is endogenous, implementation cycles arise even in the...

We show how a Schumpeterian process of creative destruction can induce rational, herd behavior by entrepreneurs across diverse sectors as if fueled by "animal spirits." Consequently, a multisector economy, in which productivity improvements are made by independent, profit-seeking entrepreneurs,...

We show how a Schumpeterian process of creative destruction can induce rational, herd-behavior by entrepreneurs across diverse sectors of the economy that may look like it is fuelled by ``animal spirits''. Consequently, a multi-sector economy, in which sector-specific, productivity improvements...

It is common amonst macroeconomists to view aggregate investment fluctuations as a rational response to fluctuating incentives, driven by exogenous movements in total factor productivity. However, this approach raises a number of questions. Why treat investments in physical capital as...

We develop a model of "intrinsic" business cycles, driven by the decentralized behaviour of entrepreneurs and firms making continuous, divisible improvements in their productivity. We show how equilibrium cycles, associated with strategic delays in implementation and endogenous innovation, arise...

The return to "sound" fiscal policy after the high budget deficits of the 1980s and early 1990s has been hailed by many as the Clinton administration's most important achievement. We evaluate post-war, U.S. fiscal policy using a generalized tax-smoothing model that allows for stochastic interest...

Au début des années 1990, la traditionnelle relation de compromis «équité-efficacité» a été mise en question par des preuves empiriques suggérant que l'inégalité des revenus avait un impact négatif sur la croissance. Cela a encouragé le développement de plusieurs théories...
