We show how to implement a competitive search equilibrium in a fully-specified DSGE environment. Competitive search, an equilibrium concept well-understood in labor market theory, offers an alternative to the commonly-used Nash bargaining in search-based macro models. Our simulation-based results show that business cycle fluctuations under competitive(More)
This paper characterizes optimal unemployment insurance (UI) over the business cycle using a model of equilibrium unemployment in which jobs are rationed in recession. It offers a simple optimal UI formula that can be applied to a broad class of equilibrium unemployment models. In addition to the usual statistics (risk aversion and micro-elasticity of(More)
I characterize cyclical fluctuations in the cross-sectional dispersion of firm-level productivity. Using the micro-estimated dispersion, or “risk,” stochastic process as an input to a baseline DSGE financial accelerator model, I assess how well the model reproduces cyclical movements in both real and financial conditions of the economy. In the model, risk(More)
We re-examine the optimality of tax smoothing from the point of view of frictional labor markets. Our central result is that whether or not this cornerstone optimal fiscal policy prescription carries over to an environment with labor market frictions depends crucially on the cyclical nature of labor force participation. If the participation rate is(More)
This paper builds a framework for the analysis of macroeconomic fluctuations that incorporates the endogenous determination of the number of producers and products over the business cycle. Economic expansions induce higher entry rates by prospective entrants subject to irreversible investment costs. The sluggish response of the number of producers (due to(More)
We study optimal fiscal and monetary policy in an environment where explicit frictions give rise to valued money, making money essential in the sense that it expands the set of feasible trades. Our main results are in stark contrast to the prescriptions of earlier flexible-price Ramsey models. Two especially important findings emerge from our work: the(More)
In the Great Recession most OECD countries used short-time work (publicly subsidized working time reductions) to counteract a steep increase in unemployment. We show that short-time work can actually save jobs. However, there is an important distinction to be made: While the rule-based component of short-time work is a cost-efficient job saver, the(More)
In this paper, using recent empirical results regarding the statistical properties of macroeconomic data revisions, we study the e¤ects of data revisions in a general equilibrium framework. We …nd that the presence of data revisions, or data uncertainty, creates a precautionary motive and causes signi…cant changes in the decisions of agents. We also …nd(More)
OBJECTIVES To assess feasibility and utility of imaging of both arms using ultrasound to facilitate transradial (TR) and transulnar (TU) coronary angiograms (CA) and intervention. BACKGROUND Despite well recognized advantages, transradial approach (TRA) has challenges that reduce procedural success including small arterial size, anatomical variations, and(More)
