This paper uses over two years of weekly scanner data from two small US cities to characterize time and state dependence of grocers' pricing decisions. In these data, the probability of a nominal adjustment declines with the time since the last price change. This reflects differences over time...

I use the Prescott (1975) hotels model to explain variations in price dispersion across goods sold by supermarkets in Chicago. I extend the theory to accounts for the monopoly power of chains and for non-shoppers. The main empirical finding is that the effect of demand uncertainty on price...

We provide a new proof of the non-emptiness of approximate cores of games with many players of a finite number of types. Earlier papers in the literature proceed by showing that, for games with many players, equal-treatment cores of their "balanced cover games", which are non-empty, can be...

I use the Baumol-Tobin approach to examine the following propositions: (a) The optimal supply of liquidity requires a government loan program in addition to paying interest on reserves held by banks, (b) The adoption of the optimal policy will crowd out private credit arrangement and will thus...

I use a flexible price version of the Prescott (1975) “hotels” model to study a dynamic model that allows for storage. The formulation follows the standard competitive analysis tradition with a non-standard definition of markets: The set of markets that open depends on the state of demand. I...

[fre] Quand l'offre de monnaie est stable, les agents économiques veulent employer la monnaie comme unité de compte dans leurs contrats futurs ; par conséquent, H faudrait, quand il se produit des perturbations monétaires, préserver les contrats émis en termes nominaux. C'est pourquoi ce...

I study the real effects of bubbles in a price-settingenvironment. Bubbles cause price dispersion and overinvestment in assets that are overvalued. And when they pop some goods are not sold and capacity is not fully utilized. I argue that a government monopoly on the creation of bubble assets is...

The paper analyzes the intermediation role of government under the assumption that it has an advantage over the private sector in collecting uncollateralized loan payments. It isshown that a government loan program may improve the welfare of all generations (including the current old generation)...
