This paper studies an intermediated market operated by middlemen with high inventory holdings. I present a directed search model in which middlemen are less likely to experience a stockout because they have the advantage of inventory capacity, relative to other sellers. The model explains why...

This paper sheds light on a recent empirical controversy about the effect of competition on price discrimination in airline markets (Borenstein and Rose (1994), Gerardi and Shapiro, (2009)). We introduce individual demand uncertainty into Hotelling's model of horizontal product differentiation...

This paper sheds light on an empirical controversy about the effect of competition on price discrimination. We introduce individual demand uncertainty into Hotelling's model of product differentiation and show that firms offer advance purchase discounts. Consumers choose between an early...

In many countries Public Employment Agencies (PEA) offer intermediation services to help as many people as possible to find work by bringing together supply and demand. Using a unique vacancy-level data-set on the number of applicants, we find positive effects of the intermediation services on...

This paper studies the role of a lender of last resort (LLR) in a monetary model where a shortage of bank’s monetary reserves (or a banking panic) occurs endogenously. We show that while a discount window policy introduced by the LLR is welfare improving, it reduces the banks’ ex ante...

This paper studies banks' liquidity provision in the Lagos and Wright model of monetary exchanges. With aggregate uncertainty we show that banks sometimes exhaust their cash reserves and fail to satisfy their depositors' need of consumption smoothing. The banking panics can be eliminated by the...

The Public Employment Agency (PEA) provides intermediation services in the labor market. We investigate the implications of having such an additional market place using a tractable search model. The intermediation services enable registered firms to pay lower wages compared to the private...

The Public Employment Agency (PEA) helps unemployed to find work and mediates PEA-registered job vacancies to job seekers via vacancy referrals. Using the spatial and temporal variation resulting from the regional roll-out of the Hartz 3 reform we are able to show that Hartz 3, which changed...
