This paper studies the effect of durability on the financing of durable assets. We show that more durable assets require larger down payments of internal funds per unit of capital making them harder to finance, because durability affects the price of an asset and hence the overall financing need...

If machines are indivisible, a vintage capital model must give rise to income inequality. If new machines are always better than old ones and if society cannot provide everyone with a new machine all of the time, inequality will result. I explore this mechanism in detail. If technology resides...

Neoclassical investment models predict that firms should make frequent, small adjustments to their capital stocks. Microeconomic evidence, however, shows just the opposite -- firms make infrequent, large adjustments to their capital stocks. In response, researchers have developed models with...

Much has been written about the seemingly less formal, more agile biotechnology industry and its extensive interactions with academia and startups, as well as its distinct scientific, manufacturing and regulatory profile. Employing a data base encompassing all 96 biologics and 212 small...

Pigouvian taxes can fully correct for market failures due to externalities, but actual policies are commonly forced to deviate from the Pigouvian ideal due to administrative or political constraints. This paper derives sufficient statistics, which require a minimum of market information, that...

This paper focuses on the specification and stability of a dynamic, stochastic, general equilibrium model of the American business cycle with sticky prices. Maximum likelihood estimates reveal that the data prefer a version of the model in which adjustment costs apply to the price level but not...

The conventional wisdom in macroeconomic modeling is to attribute business cycle fluctuations to innovations in the level of the fundamentals. Though volatility shocks could be important too, their propagating mechanism is still not well understood partly because modeling the latent volatilities...

This paper makes the following original contributions to the literature. (1) We develop a simpler analytical characterization and numerical algorithm for Bayesian inference in structural vector autoregressions that can be used for models that are overidentified, just-identified, or...

The outcome of any important macroeconomic policy change is the net effect of forces operating on different parts of the economy. A central challenge facing policy makers is how to assess the relative strength of those forces. Dynamic Stochastic General Equilibrium (DSGE) models are the leading...

This paper uses contemporaneous monetary data to carry out econometric tests of the "equilibrium" approach to modeling the relation between monetary disturbances and macroeconomic fluctuations. The theoretical analysis introduces into an equilibrium macroeconomic model the availability of...
