MMT and Government Finance: You Can't Always Get What You Want
During the past 25 years, low interest rates and highly expansionary monetary policy with little apparent inflation have created the illusion that a government can simply print money to fund exorbitant deficit spending with no repercussions. This core tenet of so-called "modern monetary theory" ignores the fact that deficit spending is constrained in the long run by a government's ability to satisfy creditors.
Inflation dynamics with search frictions : a structural econometric analysis
The New Keynesian Phillips curve explains inflation dynamics as being driven by current and expected future real marginal costs. In competitive labor markets, the labor share can serve as a proxy for the latter. In this paper, we study the role of real marginal cost components implied by search frictions in the labor market. We construct a measure of real marginal costs by using newly available labor market data on worker finding rates. Over the business cycle, the measure is highly correlated with the labor share. Estimates of the Phillips curve using GMM reveal that the marginal cost ...
On-the-job search and the cyclical dynamics of the labor market
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 creation costs low for firms, on-the-job search amplifies exogenous shocks. In our calibration, this allows the model to generate fluctuations of unemployment, vacancies, and job-to-job transitions whose magnitudes are close to the data, and leads output to be highly autocorrelated. On-the-job search ...
Instability and indeterminacy in a simple search and matching model
We demonstrate the possibility of indeterminacy and nonexistence of equilibrium dynamics in a standard business cycle model with search and matching frictions in the labor market. Our results arise for empirically plausible parameterizations and do not rely on a mechanism such as increasing returns.
Modeling Labor Markets in Macroeconomics: Search and Matching
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 markets and monetary policy.
Does Intra-Firm Bargaining Matter for Business Cycle Dynamics?
We analyze the implications of intra-firm bargaining for business cycle dynamics in models with large firms and search frictions. Intra-firm bargaining implies a feedback from the marginal revenue product to wage setting, which leads firms to over-hire in order to reduce workers' bargaining position within the firm. The keys to this effect are decreasing returns and/or downward-sloping demand. We show that equilibrium wages and employment are higher in steady state compared with a bargaining framework in which firms neglect this feedback effect. However, the effects of intra-firm bargaining ...
