摘要：We first develop a theoretical model in which individuals are embedded within a network of social relationships. We show that, conditional on being employed, the probability to find a job through social networks, relative to other search methods, increases and is concave with the size of the network. The effects are stronger for the uneducated. There is however a critical size of the network above which this probability decreases. We then test empirically these theoretical findings for Egypt u...

摘要：This paper uses auction theory, incorporating buyer asymmetry, to analyse the structure of a small market for parmal paddy in North India and to assess the implications of alternative government policies. Our results suggest that two buyers collude in this market; we are able to quantify the extent to which prices are depressed as a consequence. Such collusion probably characterizes many small grain markets in India. Government intervention in grain markets in India is pervasive, and has in re...

摘要：Our work is based on a heterogenous agent shopping-time economy in which economic agents present distinct productivities in the production of the consumption good, and differentiated access to transacting assets. The purpose of the analysis is to investigate whether this setting can lead to a positive correlation between inflation and income inequality. Our main result is to show that, provided the productivity of the interest-bearing asset in the transacting technology is high enough, it is t...

摘要：We develop a method in which vignettes-a battery of questions for hypothetical cases-are evaluated with item response theory to measure the clinical competence of doctors. The method, which allows us to simultaneously estimate competence and validate the test instrument, is applied to a sample of medical practitioners in Delhi, India. The method gives plausible results, rationalizes different perceptions of competence in the public and private sectors and pinpoints several serious problems wit...

摘要：We develop a continuum Ricardian trade model to capture both North-South trade and technology transfer via foreign direct investment (FDI) by multinational enterprises (MNEs). We show that there is a unique range of products produced in the South by MNEs. In the case of an infinitely elastic supply of expatriates, if the ability of Southern workers in absorbing Northern technology increases, then (a) the range of MNE production increases, (b) Northern workers's welfare and Southern workers' we...

摘要：Poverty makes thieves and thieves hamper economic growth. We study these linkages in a model of modem sector job creation. Job creation has two effects. Higher labor demand tends to lower crime while higher output gives more to steal, tending to increase crime. At low levels of modernization the second effect dominates and, as a consequence, the model has decreasing returns to scale. At higher levels of modernization there is increasing returns to scale due to declining crime. The economy may ...

摘要：This study introduces a fixed-rent contract with a state-contingent rent reduction widely adopted in Japan in the early 20th century, which a fixed-rent was temporary reduced in case of poor harvest. The economic implications of this contract are analyzed with a principal-agent model. It is shown that if the tenant is not too risk averse and/or the variability of the yield is not too high, then this contract is preferable for the landlord to a fixed-rent contract or a share tenancy. Preliminar...

摘要：Altruistic donors face common good problem which calls for cooperation and policy integration. On the other hand, the more united and responsible donors act towards the poor in the country that receives aid, the less domestic support does the poor get. I study these two countervailing effects of donor cooperation in different settings. Cooperation is always beneficial if donors can enforce contingent aid contracts. If contracts cannot be used, I show that cooperation can be harmful. I find tha...

摘要：Thailand has experienced economic growth well above world averages from 1960 to the recent crisis. While the controversy over Thailand and East Asian growth has discussed the role of capital accumulation versus productivity, we analyze the general equilibrium interaction between productivity and investment in an intertemporal growth model. The high growth is understood as a prolonged transition path with gradual tariff reduction and endogenous productivity driven by foreign spillover feeding c...

摘要：We develop a simple model of group-lending based on peer monitoring and moral hazard. We find that, in the absence of sequential financing or lender monitoring, group-lending schemes may involve under-monitoring with the borrowers investing in undesirable projects. Moreover, under certain parameter configurations, group-lending schemes involving either sequential financing, or a combination of lender monitoring and joint liability are feasible. In fact, group-lending schemes with sequential fi...
