We develop and empirically test a labor market model with Public Employment Agencies (PEA) in order to understand why not all vacancies use the costless services provided by the PEA. We show that both the search market and the PEA can be active in equilibrium. In such an equilibrium, workers...

I propose a simple model of merchants who are specialized in buying and selling a homogeneous good. Facing the same frictions as in the buyer-seller direct trades, merchants can make profits with an ability to buy and sell many units of the good. They set the price to compete in the market and...

This paper provides new evidence on price dispersion in the US airline industry. Using the observed fare differences between refundable and non-refundable tickets, we first document evidence on the prices passengers pay for a refund option. We find that the factors related to the value of refund...

This paper studies economy-wide fluctuations that occur endogenously in the presence of monetary and real assets. Using a standard monetary search model, we consider an economy in which agents can increase consumption, over and above what their liquid monetary asset holdings would allow,...

In a search model with two sided heterogeneity and on-the-job search, we compare collective bargaining agreements (CBA) with a decentralized bargaining outcome case. Under CBA, a union chooses a pay-scale schedule and the firm can select a wage from this pay scale after observing match quality....

This paper develops a model in which market structure is determined endogenously by the choice of intermediation mode. We consider two representative business modes of intermediation that are widely used in real-life markets: one is a middleman mode where an intermediary holds inventories which...

We develop and empirically test a labor market model with Public Employment Agencies (PEA) in order to understand why not all vacancies use the costless services provided by the PEA. We show that both the search market and the PEA can be active in equilibrium. In such an equilibrium, workers...

An advantage of collective wage agreement is that search and business-stealing externalities can be internalized. A disadvantage is that it takes more time before an optimal allocation is reached because more productive firms (for a particular worker type) can no longer signal this by posting...
