This paper integrates banks into a two-sector neoclassical growth model to account for the fact that a fraction of firms relies on banks to finance their investments. There are four major contributions to the literature. First, although banks' leverage amplifies shocks, the endogenous response...

We develop a model to rationalize and examine so-called "research bubbles", i.e. research activities based on overoptimistic beliefs about the impact of this research on the economy. Research bubbles occur when researchers selfselect into research activities and the government aggregates the...

We develop a model that incorporates salient features of growth in modern economies. We combine the expanding-variety growth model through horizontal innovations with a hierarchy of basic and applied research. The former extends the knowledge base, while the latter commercializes it. Two-way...

We employ an overlapping-generations frame-work in which young adults, confronted with such hazards and motivated by old-age provision and altruism, make decisions about investments in schooling...

We integrate bank and bond financing into a two-sector neoclassical growth model to examine the stabilization effect of endogenous bank leverage adjustment. We show that although bank leverage amplifies shocks, the increase of leverage to a decline in bank equity is an automatic stabilizer in...
