We study Ramsey-optimal fiscal policy in an economy in which product varieties are the result of forward-looking investment decisions by firms. There are two main results. First, depending on the particular form of variety aggregation in preferences, firms' dividend payments may be either...

I characterize cyclical fluctuations in the cross-sectional dispersion of firm-level productivity in the U.S. manufacturing sector. Using the estimated dispersion, or "risk," stochastic process as an input to a baseline DSGE financial accelerator model, I assess how well the model reproduces...

This paper presents a model in which some goods trade in "customer markets." In these markets, advertising plays a critical role in facilitating long-lived relationships. We estimate both policy and non-policy parameters of the model (which includes New-Keynesian frictions) on U.S. data,...

We estimate a search-based real business cycle economy using quantity data and a broad set of wage indicators, allowing the latent wage to follow a non-structural ARMA process. Under the estimated process, wages adjust immediately to most shocks and induce substantial variation in labor's share...

We characterize efficient allocations and cyclical fluctuations in a labor selection model. Potential new hires are heterogenous in the cross-section in their degree of training costs. In a calibrated version of the model that identifies costly selection with micro-level data on training costs,...

I develop a tractable, two-country, real model of macroeconomic interdependence with a role for net foreign asset dynamics. Absence of Ricardian equivalence in an overlapping generations structure ensures existence of a well-defined, endogenously determined, steady-state, international...

We develop a stochastic, general equilibrium, two-country model of trade and macroeconomic dynamics. Productivity differs across individual, monopolistically competitive firms in each country. Firms face a sunk entry cost in the domestic market and both fixed and per-unit export costs. Only...

This paper develops a small open economy, sticky-price model with a role for current account dynamics in the transmission of shocks. I solve the stationarity problem of incomplete markets, open economy models by adopting an overlapping-generations structure. I model nominal rigidity by assuming...

We compare the performance of a currency board arrangement, inflation targeting, and dollarization in a small open, developing economy with liberalized capital account. We focus explicitly on the transmission of shocks to currency and country risk premia in international financial markets and on...
