When does it pay a coalition of buyers and a coalition of sellers to by-pass a noncooperative market outcome by negotiating an alternative contract? Should these collective contracts be allowed? This paper investigates one source of the incentive for collective contracting: the failure of...

Why are some cities specialised and others diversified? What are the advantages and disadvantages of urban specialisation and diversity? To what extent does the structure of cities, and the activities of firms and people in them, change over time? How does the sectoral composition of cities...

In this paper I examine the socially optimal allocation in a random matching economy. The optimal allocation is supported by punishment to defections, using the public record of agents<92> transaction. However, public record-keeping is imperfect, as an agent<92>s transaction is updated into the public...</92></92>

Using a matched employer-employee data set of manufacturing plants in three sub-Saharan countries, I compare the marginal productivity of different categories of workers with the wages they earn. A methodological contribution is to estimate the firm level production function jointly with the...

Bedevilling the ongoing debate about changes in real-incomes in late-medieval western Europe, especially during the so-called 'Golden Age of the Labourer', is the very troubling issue of 'wage-stickiness'. The standard and long-traditional explanation for this supposed 'Golden Age' of rising...

This paper investigates the consequences of imperfect and uneven factor market development for farm efficiency in rural China. In particular, we estimate the extent to which an inverse relationship in farm productivity can be attributed to the administrative (instead of market) allocation of...

In this paper we study the inefficiencies of the monetary equilibrium and optimal monetary policies in a search economy. We show that the same frictions that give fiat money a positive value generate an inefficient quantity of goods in each trade and an inefficient number of trades (or search...

This paper analyses the major changes in textile products, production costs, prices, and market orientations during the era when the 'draperies' or cloth industries of the late-medieval Low Countries had become increasingly dependent upon northern markets and the German Hanseatic League as the...

In this paper I study the assignment between machines of heterogeneous qualities and workers of heterogeneous skills in an infinite-horizon economy with matching frictions. I characterize first the efficient assignment and then the decentralizing market equilibrium. The efficient allocation...

I study a budget-constrained, private-valuation, sealed-bid sequential auction with two incompletely-informed, risk-neutral bidders in which the valuations and income may be non-monotonic functions of a bidder\\'s type. Parameters permit the existence of multiple equilibrium symmetric bidding...
