The effect of a widening of the distribution of income upon society's choice of the amount of redistribution is a balancing of two opposing forces: the increase in redistribution in response to the increased ratio of mean to median income and the decrease in response to the greater advertising...

We solve for an S-shaped schedule for market size for a new product that undergoes gradual widespread adoption. We hypothesize that the speed of market expansion is positively related to the current proÂ…t per unit being produced. In a mature market the unit profit is relatively low.

I propose a model of the housing market using a search framework with asymmetric information in which sellers are unable to commit to asking prices announced ex ante. Relaxing the commitment assumption prevents sellers from using price posting as a signalling device to direct buyers' search....

Can central counterparty (CCP) clearing control counterparty risk in the presence of risk taking that can aggravate such risk? When counterparty risk is not observable, I show that central clearing leads to higher collateral requirements for two different reasons. Without collusion about risk...

We set out a simple four sector macro model of the economy of the Roman Empire during a period of considerable economic prosperity. Our focus is on gold coins as currency and the seignorage which the government used to fund its activities. We solve numerically for a balanced growth...

We present an aggregate four good model (consumption, investment and two government goods) in which the current flows of one government good are in part pure public intermediate goods. The other public good has "final" services for households. We are interested in a benefit approach to charging...

Governments fund public universities based on the number of registered students and lump sum transfers. Such policy induces universities to compete for student recruitment. I show that such rule can lead to an inefficient allocation of resources in which universities compete for the same...

This paper establishes a theoretical model to examine the LOLR policy when a central bank cannot distinguish between solvent and insolvent banks. We study two cases: a case where the central bank cannot screen insolvent banks and a case where the central bank can only imperfectly screen...

We set out a city as a price-taking exporter and importer with its own local structure (housing (land per household) and a local pure public good are produced endogenously). We improve labor efficiency in the export sector, observe a jump in the local wage, and trace the impact, particularly on...

KolstadÂ’'s (1994) model of intertemporal, competitive supply to a linear market from two distinct exhaustible resource deposits admits two different interior solutions - one with the low cost deposit "earning" the higher resource rent and the other with the low cost deposit "earning" the...
