We provide an infinite-horizon model of a production economy with credit-driven stock- price bubbles, in which firms meet stochastic investment opportunities and face credit constraints. Capital is not only an input for production, but also serves as collateral. We show that bubbles on this...

This paper develops a macroeconomic model with a banking sector in which banks face endogenous borrowing constraints. There is no uncertainty about economic fundamentals. Banking bubbles can emerge through a positive feedback loop mechanism. Changes in household confidence can cause the collapse...

Entrepreneurs face significant non-diversifiable business risks. We build a dynamic incompletemarkets model of entrepreneurial firms to demonstrate the important implications of nondiversifiable risks for entrepreneurs’ interdependent consumption, portfolio allocation, financing, investment,...

This paper presents an analytically tractable continuous-time general equilibrium model with investment irreversibility and fixed adjustment costs. In the model, there is a continuum of firms that are subject to idiosyncratic shocks to capital. Although the presence of investment frictions...

This paper studies the impact of corporate tax policy on the economy in the presence of both convex and nonconvex capital adjustment costs in a dynamic general equilibrium model. We show that corporate tax policy generates both intensive and extensive margin effects via the channel of marginal...

Entrepreneurs face significant non-diversifiable business risks. We build a dynamic incompletemarkets model of entrepreneurial finance to demonstrate the important implications of nondiversifiable risks for entrepreneurs’ interdependent consumption, portfolio allocation, financing, investment,...
