We examine a monetary economy wherein endogenous asset market segmentation permits the extent of household participation in open market operations to vary smoothly with changes in aggregate conditions. While we impose no stickiness at the microeconomic level in either prices or portfolio...

We study an economy where households face transactions costs of participating in the housing market. In response to these costs, households choose to buy and sell houses infrequently. This, in turn, implies that the value of the typical transaction is large relative to income. In this way our...

We consider business cycles driven by exogenous changes in total factor productivity and by credit shocks. The latter are financial shocks that worsen borrowers cash on hand and reduce the fraction of collateral lenders can seize in the event of default. Our nonlinear loan rate schedules drive...

We study the cyclical implications of endogenous firm-level entry and exit decisions in a dynamic, stochastic general equilibrium model wherein firms face persistent shocks to both aggregate and individual productivity. The model we explore is in the spirit of Hopenhayn (1992). Firms' decisions...

Recent empirical analysis has found nonlinearities to be important in understanding aggregated investment. Using an equilibrium business cycle model, we search for aggregate nonlinearities arising from the introduction of nonconvex capital adjustment costs. We find that, while such costs lead to...

The authors examine a monetary economy where households incur fixed transactions costs when exchanging bonds and money and, as a result, carry money balances in excess of current spending to limit the frequency of such trades. As only a fraction of households choose to actively trade bonds and...

We develop a monetary model that is unique in its ability to deliver a negative correlation between aggregate consumption growth and short-term real interest rates consistent with U.S. data. The essential ingredient to this success is endogenous asset market segmentation permitting the extent of...

We solve equilibrium models of lumpy investment wherein establishments face persistent shocks to common and plant-specific productivity. Nonconvex adjustment costs lead plants to pursue generalized (S, s) rules with respect to capital; thus, their investments are lumpy. In partial equilibrium,...
