Directed Search with Multiple Job Applications

We develop an equilibrium directed search model of the labor market where workers can simultaneously apply for multiple jobs. Our main theoretical contribution is to integrate the portfolio choice problem faced by workers into an equilibrium framework. All equilibria of our model exhibit wage dispersion. Consistent with stylized facts, the density of wages is decreasing and higher wage firms receive more applications per vacancy. Unlike most models of directed search, the equilibria are not constrained efficient.

On the Game-Theoretic Foundations of Competitive Search Equilibrium

We provide a unified directed search framework with general production and matching specifications that encompass most of the existing literature. We prove the existence of subgame perfect Nash equilibria in pure firm strategies in a finite version of the model. We use this result to derive a more complete characterization of the equilibrium set for the finite economy and to extend convergence results as the economy becomes large to general production and matching specifications. The latter extends the microfoundations for the standard market utility assumption used in competitive search models with a continuum of agents to new environments.

MARKET POWER AND EFFICIENCY IN A SEARCH MODEL

We build a theoretical model to study the welfare effects and resulting policy implications of firms’ market power in a frictional labor market. Our environment has two main characteristics: wages play a role in allocating labor across firms and there is a finite number of agents. We find that the decentralized equilibrium is inefficient and that the firms’ market power results in the misallocation of workers from the highto the low-productivity firms. A minimum wage forces the low-productivity firms to increase their wage, leading them to hire even more often thereby exacerbating the inefficiencies. Moderate unemployment benefits can increase welfare because they limit firms’ market power by improving the workers’ outside option.

Heterogeneous Firms in a Finite Directed Search Economy

We consider a directed search model for a finite economy with heterogeneous firms in two informational environments. In the first, the productivity of all firms is publicly observed. We prove existence of equilibria in pure posting strategies by firms and show that wage dispersion is driven by fundamentals. That is, more productive firms post higher wages and wage dispersion is absent when firms are homogeneous. When firms have heterogeneous productivities the equilibrium is not constrained efficient. In the second environment the productivity level of each firm is private information. The main results extend to this environment: Equilibria in pure strategies exist; strategies are increasing in productivity; and constrained efficiency does not obtain. When the productivity level of all firms is drawn from the same distribution, symmetric equilibria exist and the ranking of wages equals that of productivity.

The Challenge of Trade Adjustment in Greece

Greece’s trade deficit declined by 10% of GDP between 2007 and 2012, removing one of the great economic imbalances of the pre-crisis years. However, this reduction was achieved exclusively through import compression while exports fell over that period, thereby worsening the economic crisis. This chapter studies Greece’s export underperformance in comparison to Ireland, Portugal and Spain as well as Greece’s own pre-crisis experience. The main findings are that (1) given past performance, Greece’s exports should have increased by 25%, rather than drop by 5% between 2007 and 2012; (2) labor markets have adjusted to the new economic environment; (3) product markets did not adjust, hindering the recovery of competitiveness; (4) export underperformance is responsible for a third of the decline in GDP since 2007. We find that the business environment and firm size distribution in Greece are also hindering the necessary adjustment.

The Greek Crisis: Origins and Implications

The conventional wisdom is that the Greek and Eurozone crises are the result of fiscal profligacy, which has justified austerity as the primary policy to exit the crisis. This interpretation of the crisis fits the case of Greece and, to a lesser extent, Portugal, but cannot explain why Ireland and Spain had to request assistance, given that prior to 2008 they had lower deficits and public debt than most Eurozone countries. The features that set the four peripheral countries apart from the rest of the Eurozone are the large current account deficits they all experienced before 2008. This observation suggests that the origins of the Eurozone crisis are to be found in external rather than fiscal imbalances. The implication is that the exclusive policy focus on reducing fiscal deficits is misguided and the four peripheral countries should be helped to reduce external deficits by recovering competitiveness.

A Model of Money with Multilateral Matching, Second Version

We develop a model of monetary exchange that avoids several common criticisms of the recent microfoundations literature. First, rather than random matching, we assume that buyers know the location of all sellers, and hence the process of finding a partner is deterministic, although trade is still stochastic since the number of buyers visiting a given seller is random. Second, given multilateral matching, rather than bargaining, we assume that goods are allocated according to second-price auctions. Third, given this mechanism, we do not have to assume agents can observe each others money holdings or preferences, as is necessary for tractability with bargaining. A novel result is that homogeneous buyers hold different amounts of money, leading to equilibrium price dispersion. We find the closed-form solution for the distribution of money holdings. We characterize equilibrium and efficient monetary policy.
