We examine the impact of real oil price shocks on labor market flows in the U.S. We first use smooth transition regression (STR) models to investigate to what extent oil prices can be considered as a driving force of labor market fluctuations. Then we develop and calibrate a modified version of...

We study whether segmented labor markets with flexibility at the margin (e.g., just affecting fixed-term employees) can achieve similar volatility than fully deregulated labor markets. Flexibility at the margin produces a gap in separation costs among matched workers that cause fixed-term...

We study the business cycle behavior of segmented labor markets with flexibility at the margin (e.g., just affecting fixed-term employees) and ask whether these types of labor markets can display similar volatilities as fully deregulated ones. We present a matching model with temporary and...

This paper will argue that since the ratio of government debt to GDP cannot diverge to infinity, fiscal collapse is not possible. Using a macroeconomic model of a growing economy with a simple microeconomic foundation about consumers’ behavior, with overlapping generations model in mind, we...

In recent years, a school of economics called MMT (Modern Monetary Theory) has been attracting attention, but it has not been analyzed theoretically or mathematically. This study aims to provide a theoretical basis for the skeleton of the MMT argument, while maintaining the basics of the...

In a Walrasian labor market, the labor income share is constant under the assumptions of a Cobb-Douglas production function and perfect competition. Given the observed decline of the labor share in recent decades, this paper relaxes these assumptions, proposes a time-series calculation of the...

In his "The World’s smallest macroeconomic model” (Krugman(1999)), Paul Krugman argued that under the assumption of price rigidity, a shortage of money supply leads to underemployment or recession, so increasing money supply can eliminate underemployment and restore full employment. But, how...

The purpose of this paper is to show, using a simple two-periods overlapping generations (OLG) model in which goods are produced solely by labor in a monopolistically competitive industry, that a continuous budget deficit is necessary to maintain full-employment under economic growth driven by...

According to the concept of "fiscal discipline" public finance must be balanced, at least in the long run. The school of thought known as MMT (Modern Monetary Theory), which has been gaining attention recently, rejects this idea. However, it is often pointed out that MMT lacks the mathematical...

This paper investigates the role of mismatch between job seekers and job openings for the forecasting performance of a labor market matching function. In theory, higher mismatch lowers matching efficiency which increases the risk that the vacancies cannot be filled within the usual period of...
