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...

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...

According to the standard union bargaining model, unemployment benefits should have big effects on wages, but product market prices and productivity should play no role in the wage bargain. We formulate an alternative strategic bargaining model, where labour and product market conditions...

This paper studies infinite-horizon bargaining between a seller and multiple buyers when externalities are present. We extend the analysis in Jehiel & Moldovanu (1995a) by allowing for both pure and mixed equilibria. A characterization of the stationary subgame perfect equilibria in generic...

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...

International immigration flows 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...
