摘要：This paper demonstrates the importance of allowing for structural breaks in the time-series when investigating the relationship between the official and the parallel markets in foreign exchange. Only when structural breaks are accounted for does a relationship emerge in Nigeria. We find that over the period 1980-1993, the official rate has Granger-caused the parallel rate.

摘要：The paper examines the optimal saving policy for a small exhaustible resource-exporting economy (ERE) that has an exhaustible asset and a reproducible capital stock. It shows that, both in magnitude and time profile, the optimal saving policy for an ERE sharply differs from (a) that of a nonextractive economy and (b) that derived from the conventional models of growth with exhaustible resources. These differences arise from the specific economic features that distinguish the small resource-exp...

摘要：Using a unique sample of rotating savings and credit association (Rosca) members from Jamaica, we provide the first econometric tests of the recent theoretical advances in the literature on Roscas, and find considerable support for an economic theory of Roscas. We find, for example, that payments to the Rosca leader significantly enhance the sustainability of the Rosca, and that the contractual relationship between the leader and other Rosca members is 'transaction cost minimizing' - when the ...

摘要：This paper develops a model of a (laissez-faire) decentralized banking system in which banks are shown to both underinvest in, and undertransmit expertise in long-term industrial finance. Government support for one financial institution ('the development bank') can serve to reduce these problems, but unqualified government support alone is not enough. The efficiency of government sponsorship can be enhanced if certain conditions are attached to that sponsorship. Crucially, these include target...

摘要：The model developed in this paper attempts to provide an explanation of the fact that Icelandic vessel owners and Icelandic skippers do not share costs of operation of a vessel. Tn the model, a skipper is contracted to take a fishing vessel to the fishing ground. The skipper is remunerated with a share of the catch, subject to an agreed minimum. Skippers and vessel owners are modelled as if risk-neutral. Skippers develop a fishing strategy which is more costly, the higher the value of the pote...

摘要：This paper compares four different modelling approaches to agricultural expansion and deforestation, and explores the implications of assumptions about the household objectives, the labour market, and the property rights regime. A major distinction is made between population and market based explanations. Many of the popular policy prescriptions are based on the population approach, assuming subsistence behaviour and limited market integration. Within a more realistic-particularly for the long...

摘要：The paper develops a new explanation of sharecropping based on the idea of an incentive equilibrium. It considers a set-up in which a few landlords in a village confront the choice of cultivating their farms by adopting different tenurial arrangements, ranging from owner operation, through the fixed-rental system to sharecropping. These landlords are the only sources of employment in the village, and compete in the wages they pay to their workers. In such an environment sharecropping is explai...
