We show that in microdata, as well as in a search and matching model with flexible wages for new hires, wage rigidities of incumbent workers have substantial effects on separations and unemployment volatility. Allowing for an empirically relevant degree of wage rigidities for incumbent workers...

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...

We develop a New Keynesian model with staggered price and wage setting where downward nominal wage rigidity (DNWR) arises endogenously through the wage bargaining institutions. It is shown that the optimal (discretionary) monetary policy response to changing economic conditions then becomes...

We develop a DSGE model with firm-specific labor where firm-level wage bargaining and price setting are subject to Calvo-type staggering. This is in general an intractable problem due to complicated intertemporal dependencies between price and wage decisions. However, the problem is...

How are wages set in an open economy? What role is played by demand pressure, international competition, and structural factors in the labour market? How important is nominal wage rigidity and exchange rate policy for the medium term evolution of real wages and competitiveness? To answer these...

We analyze a model where the federal government provides risk sharing arrangements to municipalities investing in a local public good. The risk sharing arrangements are an income equalization system and a system allowing for a soft budget constraint, i.e., a bailout. Our main result is that a...

In bargaining between two sellers and one buyer on prices and quantities, strategic inefficiencies arise. By reallocating between the last agreement and the first, the buyer can increase it's share of the surplus. With symmetric sellers producing substitutes, the quantities in the first...

The purpose of this paper is to analyze bargaining between a firm and a finite set of workers. In particular employment choice and the payoffs in equilibrium are studied. In the model, the firm first selects the workers it wants to hire. The selected workers then decide whether they want to...

In an analysis of the formation of unions within a single firm, this paper addresses conditions under which encompassing unions form. It is shown that a production function satisfying decreasing marginal productivity leads to the formation of encompassing unions. This result holds for different...

This paper studies a model of how political parties use resources for campaigning to inform voters. We show existence of equilibrium under mild assumptions for an arbitrary number of parties. The main result is that if the parties are more extreme, then they spend less resources on campaigning...
