We show that business cycles reduce welfare through a decrease in the average level of employment in a labor market search model with learning on-the-job and skill loss during unemployment. A negative correlation between unemployment and vacancies implies, via the concavity of the matching...

We show that in micro data, as well as in a search and matching model with endogenous separations and rigid wages, separations and hence employment volatility are non-neutral to wage rigidities of incumbent workers. In contrast to when all wages are flexible, the standard deviation of...

Gesell taxes on money holdings have received attention in recent decades as a way of alleviating the zero lower bound on interest rates. Less known is that such a tax was the predominant method used to generate seigniorage in large parts of medieval Europe for around two centuries. When the...

Recent work has shown that microeconomic shocks at the firm and sector level account for a substantial share of output volatility. We examine whether this relationship holds for house price growth volatility, which also declined during the Great Moderation and increased after 2001. Using a novel...

International immigration ows are large, volatile and have recently increased. This paper is the first to study the dynamic effects of immigration shocks on the economy within a search and matching framework. Since the microdata indicates that some of the key macroeconomic effects of immigration...

Swedish abstract: Periodiska myntindragningar tillämpades under nästan 200 år i stora delar av medeltidens Europa. Gamla mynt förklarades ogiltiga och skulle växlas in mot nya till på förhand bestämda kurser och datum. Denna skatt var likvärdig med en modern Gesellskatt på pengainnehav...

Macroeconomic research often relies on structural vector autoregressions to uncover empirical regularities. Critics argue the method goes awry due to lag truncation: short lag-lengths imply a poor approximation to DSGE-models. Empirically, short lag-length is deemed necessary as increased...

We analyze a bargaining model where there is a long-term relationship between a seller and a buyer and there is bargaining over a sequence of surpluses that arrives at fixed points in time. Markov Perfect Equilibria are analyzed and equilibrium payoffs characterized. The transfers between the...

A monetary system called periodic re-coinage was used during almost 200 years in large part of medieval Europe. Old coins were frequently declared invalid and had to be exchanged for new ones for an exchange fee. This system – which is equivalent to a Gesell tax – required a limited coin...
