This paper investigates the determinants of demand for schooling in Kenya. Probit and ordered probit methods are used to model enrolment and attainment respectively. The results show that child characteristics, parental education and other household characteristics, quality and cost of schooling are important determinants of demand for education services in Kenya. The results further show that girls would be more affected by policy changes than boys. The findings call for targeting in efforts to boost and sustain demand for schooling in Kenya. The study recommends immediate policy interventions focusing on improving quality of education and poverty alleviation. 相似文献

Banking with nominal deposits and inside money 总被引:1,自引:0,他引:1
Bank runs in the literature take the form of withdrawals of demand deposits payable in real goods, which deplete a fixed reserve of goods in the banking system. That framework describes traditional bank runs based on currency withdrawals as occurred historically in the US and more recently in developing countries. However, in a modern banking system, large withdrawals typically take the form of electronic payments of inside money, with no analog of a depletion of a scarce reserve from the banking system. In a new framework of nominal demand deposits repayable in inside money, pure liquidity-driven bank runs do not occur. If there were excessive early withdrawals, nominal deposits would hedge the bank and flexible monetary prices in the goods market would limit real consumption. The maturity mismatch of short term liabilities and long term assets is not sufficient for multiple equilibria bank runs without other frictions. A key role of the bank is to ensure optimal real liquidity, which allows markets to optimally distribute consumption goods through the price mechanism. 相似文献

In this paper, we question the role of added fats on health disparities in the French case and its policy implications. Since low-status populations are proven to have more nutritional pathologies, can we evidence fat consumption specificity in poor populations? We first verify the strong sensitivity of fat consumption to income and education, criteria which both characterize deprived populations. We estimate a demand system taking into account the selection issue. For this we propose a modification of the Shonkwiler and Yen's procedure which, unlike Heckman's, allows participation on every market of products to be controlled for. We use the latter procedure on a set of seven fat categories which have different, including opposite, health attributes. Our results show that segmentation following income and/or education essentially affects price elasticities. This offers different perspectives for health policies. Controlling fat consumption through prices appears easier among low-income households than among low-education households. 相似文献

An experimental store was created to evaluate initial demand for locally produced and guaranteed tender steak products as a more realistic alternative to contingent valuation (CV) and dichotomous-choice experimental methods. Strengths of the approach are incentive compatibility, a realistic consumption set, and a familiar choice environment. Consumers selected among USDA Choice, premium quality, lean, guaranteed tender and locaily produced strip steaks. A double-hurdle count data model indicated initial willingness-to-pay (WTP) for locally produced steak comparable to prior CV results, but demand was highly elastic. Demand for premium quality steak crowded out demand for the guaranteed tender product, contrasting with prior dichotomous-choice experimental results. 相似文献

Swarming demands and seasonality periodically induce a stringent capacity problem in the made-to-order (MTO) B2B environment. Desirable order admission is a tactic with minimal application cost for handling this problem. A real-time order admission problem with limited major-customer population and batch-size demand with heterogeneous distributions is modeled as a dynamic and stochastic knapsack problem. The optimality of the Markovian deterministic reward-threshold policy is verified. Optimal policy, basic policy, and the capacity rationing method are compared in the designed experiment. The numerical results suggest great potential for increasing profit using the optimal order admission policy for MTO businesses. 相似文献

In a neoclassical economy with endogenous capital- and labor-augmenting technical change the steady-state growth rate of output per worker is shown to increase in the elasticity of substitution between capital and labor. This confirms the assessment of Klump and de La Grandville (2000) that a greater elasticity of substitution allows for faster of economic growth. However, unlike their findings my result applies to the steady-state growth rate. Moreover, it does not hinge on particular assumptions on how aggregate savings come about. It holds for any household sector allowing savings to grow at the same rate as aggregate output. 相似文献

This paper presents and estimates an input–output model in which input coefficient changes are functions of changing prices. The model produces results that mirror the characteristics of input demand functions based on the model of cost minimization subject to producing a desired level of output. It does not rely on the specification of a functional form for input coefficients, and it does not require the use of assumptions regarding the elasticity of substitution. Instead, it allows the actual price and coefficient changes that occur between periods to identify the implicit elasticities and own- and cross-price derivatives. Using this model, it is shown how accurate measures of price effects, including the full array of own and cross-elasticities of demand, can be estimated for models comprising up to 15 sectors given data for only two time periods. 相似文献
