Once the zero bound on nominal interest rates is taken into account, Taylor-type interest rate feedback rules give rise to unintended self-fulfilling decelerating inflation paths and aggregate fluctuations driven by arbitrary revisions in expectations. These undesirable equilibria exhibit the...

This paper explores some macroeconomic implications of including household production in an otherwise standard real business cycle model. The authors calibrate the model on the basis of microeconomic evidence and long-run considerations, simulate it, and examine its statistical properties. They...

Investment of US firms responds asymmetrically to Tobin’s Q: investment of established firms—“intensive” investment—reacts negatively to Q whereas investment of new firms—“extensive” investment—responds positively and elastically to Q. This asymmetry, we argue, reflects a...

We propose a theory of the market for venture capital that links the excess return to venture equity to the scarcity of venture capitalists (VCs). High returns make the VCs more selective and eager to terminate nonperforming ventures because they can move on to new ones. The scarcity of VCs...

This paper studies the evolution of a competitive industry in which a fixed number of firms reduce costs by innovating and by imitating their rivals' technologies. As the firms' technologies gradually improve, industry output expands and price falls. Technological leaders tend to rely on...

This paper develops a model of sectoral labor mobility and tests its main implications. The model nests two distinct hypotheses on the origin of mobility: (1) sectoral shocks and (2) worker-employer mismatch. We estimate the relative importance of each hypothesis and find that the bulk of labor...
