We introduce inventories into an otherwise standard New Keynesian model and study the implications for inflation dynamics. Inventory holdings are motivated as a means to generate sales for demand-constrained firms. We derive various representations of the New Keynesian Phillips curve with...

I specify a simple search and matching model of the labor market and estimate it on unemployment and vacancy data for Hong Kong over the period 2000-2010 using Bayesian methods. The model fits the data remarkably well. The estimation shows that the main driver of fluctuations in the labor market...

We use a Bayesian time-varying parameter structural VAR with stochastic volatility to investigate changes in both the reduced-form relationship between vacancies and the unemployment rate, and in their relationship conditional on permanent and transitory output shocks, in the post-WWII United...

One of the most striking aspects of the Great Recession in the United States is the persistently high level of unemployment despite an uptick in economic activity and an increased willingness by firms to hire. This has stimulated a debate on mismatch in the labor market. The argument is that...

Beginning in the mid-1980s, the nature of U.S. business cycles changed in important ways, as made evident by distinctive shifts in the comovement and relative volatilities of key economic aggregates. These include labor productivity, hours, output, and inventories. Unlike the widely documented...

We argue in this paper that the Great Inflation of the 1970s can be understood as the result of equilibrium indeterminacy in which loose monetary policy engendered excess volatility in macroeconomic aggregates and prices. We show, however, that the Federal Reserve inadvertently pursued policies...

We use Bayesian time-varying parameters structural VARs with stochastic volatility to investigate changes in both the reduced-form and the structural correlations between business inventories and either sales growth or the real interest rate in the United States during both the interwar and the...

We present and discuss the simple search and matching model of the labor market against the background of developments in modern macroeconomics. We derive a simple representation of the model in a general equilibrium context and how the model can be used to analyze various policy issues in labor...

We derive and estimate a New Keynesian Phillips curve (NKPC) in a model where consumers are assumed to have deep habits. Habits are deep in the sense that they apply to individual consumption goods instead of aggregate consumption. This alters the NKPC in a fundamental manner as it introduces...

We develop a business cycle model with search and matching frictions in the labor market and show that on-the-job search generates substantial amplification and propagation. Rising search by employed workers in an expansion amplifies the incentives of firms to post vacancies. By keeping job...
