January 2014An Economical Business-Cycle Model
with Emmanuel Saez: w19777
We construct a microfounded, dynamic version of the IS-LM-Phillips curve model by adding two elements to the money-in-the-utility-function model of Sidrauski (1967). First, real wealth enters the utility function. The resulting Euler equation describes consumption as a decreasing function of the interest rate in steady state–the IS curve. The demand for real money balances describes consumption as an increasing function of the interest rate in steady state–the LM curve. The intersection of the IS and LM curves defines the aggregate demand (AD) curve. Second, matching frictions in the labor market create unemployment. The aggregate supply (AS) curve describes output sold for a given market tightness. Tightness adjusts to equalize AD and AS curve for any price process. With a rigid price pr...
February 2013A Model of Aggregate Demand and Unemployment
with Emmanuel Saez: w18826
We present a static model of aggregate demand and unemployment. The economy has a nonproduced good, a produced good, and labor. Product and labor markets have matching frictions. A general equilibrium is a set of prices, market tightnesses, and quantities such that buyers and sellers optimize given prices and tightnesses, and actual tightnesses equal posted tightnesses. In each frictional market, there is one more variable than equilibrium condition. To close the model, we take all prices as parameters. We obtain the following results: (1) unemployment and unsold production prevail in equilibrium; (2) each market can be slack, efficient, or tight if the price is too high, efficient, or too low; (3) product market tightness and sales are positively correlated under aggregate demand shocks b...
November 2010Optimal Unemployment Insurance over the Business Cycle
with Camille Landais, Emmanuel Saez: w16526
This paper examines how optimal unemployment insurance (UI) responds to the state of the labor market. The theoretical framework is a matching model of the labor market with general production function, wage-setting mechanism, matching function, and preferences. We show that optimal UI is the sum of a conventional Baily-Chetty term, which captures the trade-off between insurance and job-search incentives, and a correction term, which is positive if UI brings labor market tightness closer to its efficient level. The state of the labor market determines whether tightness is inefficiently low or inefficiently high. The response of optimal UI to the state of the labor market therefore depends on the effect of UI on tightness. For instance, if the labor market is slack and tightness is ineffici...
