Markov models introduce persistence in the mixture distribution. In time series analysis, the mixture components relate to different persistent states characterizing the state-specific time series process. Model specification is discussed in a general form. Emphasis is put on the functional form...

Modern Money Theory (MMT) has generated considerable scrutiny and discussions over the past decade. While it has gained some acceptance in the financial sector and among some politicians, it has come under strong criticisms from all sides of the academic spectrum and from conservative political...

Global inflation has risen sharply from its lows in mid-2020, on rebounding global demand, supply bottlenecks, and soaring food and energy prices, especially since the Russian Federation's invasion of Ukraine. Markets expect inflation to peak in mid-2022 and then decline, but to remain elevated...

This paper examines the dynamics of Keynesian models that incorporate feedback effects from the labor market to income distribution, investment, aggregate demand and output. A baseline version of the model can generate endogenous growth cycles, but cumulative divergence and economic collapse...

This paper traces the history of China's reform of its monetary policy framework and analyzes its success and problems. In the context of financial marketization and the failure of the quantity-targeting framework, the People's Bank of China transformed its monetary policy framework toward one...

We present a model of aggregate fluctuations in which monopolistic firms face sunk costs to enter the production process and labor markets are characterized by search and matching frictions. Entrants post vacancies and are matched to idle workers. Our specification of sunk costs gives rise to a...

The purpose of this paper is to explore the microfoundations of the observed asymmetric movement in aggregate unemployment rates. Using U.S. data, we find that individual labor force participation responds asymmetrically to changes in local labor market conditions, consistent with the pattern of...

Higher oil-price shocks benefit unskilled workers relative to skilled workers: At the business-cycle frequency, energy prices and the skill premia display a strong, negative correlation. We assess the robustness of this negative correlation using several methods and data sources, including...

This paper is concerned with the business cycle dynamics in search-and-matching models of the labor market when agents are ex post heterogeneous. We focus on wealth heterogeneity that comes as a result of imperfect opportunities to insure against idiosyncratic risk. We show that this...

We explore the role of real wage dynamics in a New Keynesian business cycle model with search and matching frictions in the labor market. Both job creation and destruction are endogenous. We show that the model generates counterfactual inflation and labor market dynamics. In particular, it fails...
