Emerging economies have high shares of self-employed individuals running owner-only firms who, in contrast to many salaried firms, have little access to formal financing and therefore rely on informal financing (input credit) from other firms. We build a small open economy real business cycle...

Changes in monetary policy are typically implemented gradually, an empirical observation known as interest-rate smoothing. We propose an explanation of optimal interest-rate smoothing by applying the recent lesson from the related literature on the monetary transmission mechanism that...

We characterize efficient allocations and business cycle fluctuations in a labor selection model. Due to forward-looking hiring and labor supply decisions, efficiency entails both static and intertemporal margins. We develop welfare-relevant measures of marginal rates of transformation and...

Ramsey models of fiscal and monetary policy with perfectly-competitive product markets and a fixed supply of capital predict highly volatile inflation with no serial correlation. In this paper, we show that an otherwise-standard Ramsey model that incorporates capital accumulation and habit...

Amid total factor productivity (TFP) shocks job-to-job flows amplify the volatility ofunemployment, but the aggregate implications of job-to-job flows amid financial shocks are lessunderstood. To develop such understanding we model a general equilibrium labor-searchframework that incorporates...

We analyze the quantitative labor market and aggregate effects of a carbon tax in a framework with pollution externalities and equilibrium unemployment. Our model incorporates endogenous labor force participation and two margins of adjustment influenced by carbon taxes: firm creation and green...
