Stock price bubbles are often on productive assets and occur in a sector of the economy. In addition, their occurence is often accompanied with credit booms. Incorporating these features, we provide a two-sector endogenous growth model with credit-driven stock price bubbles. Bubbles have a...

We incorporate long-term defaultable corporate bonds and credit risk in a dynamic stochastic general equilibrium business cycle model. Credit risk ampli¯es aggregate tech- nology shocks. The debt-capital ratio is a new state variable and its endogenous movements provide a propagation mechanism....

Stock price bubbles are often on productive assets and occur in a sector of the economy. In addition, their occurence is often accompanied by credit booms. Incorporating these features, we provide a two-sector endogenous growth model with credit-driven stock price bubbles. Bubbles have a credit...

In the presence of both convex and nonconvex capital adjustment costs in a dynamic general equilibrium model, corporate tax policy generates both intensive and extensive margin effects via the channel of marginal Q. Its impact is determined largely by the strength of the extensive margin effect,...

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

We present an estimated DSGE model of stock market bubbles and business cycles using Bayesian methods. Bubbles emerge through a positive feedback loop mechanism supported by self-fulfilling beliefs. We identify a sentiment shock which drives the movements of bubbles and is transmitted to the...

We construct a model to capture the Keynesian idea that production and employment decisions are based on expectations of aggregate demand driven by sentiments, and that realized demand follows from the production and employment decisions of firms. We cast the Keynesian idea into a simple model...
