This paper is concerced with the role of externalities and nonconvexities in agglomeration (concentration) of urban population and production. The paper examines whether, indeed, as often asserted, the external aspect of scale economies (diseconomies) deters (enhances) agglomeration.

We consider discrete versions of independent, private-value, first-price auctions. We show for any fixed finite set of possible bids, if the number of participants is large enough, then the set of rationalizable bids involves all players bidding the highest bid that is lower than their private...

It is common to explain the market failure in efficiently distributing the population among urban areas by externalities associated with unpriced transportation congestion and external scale economies in the supply of private and public goods. Consequently, in prescribing the appropriate...

We consider zero-monotonic environments with transferable utility and propose a simple non-cooperative game to determine how the surplus generated by cooperation is to be shared. First, the players bid for the right to propose a sharing of the surplus. Second, after the winner pays the bids, she...
