The purpose of this study is to consider the question of whether characteristics of applicants for federally subsidized housing can be used in predicting whether one is accepted or rejected by management as a tenant. Using probit analysis, a statistical model was developed for use in assisting management in objectively screening applicants. Factors found significant in determining the probability of acceptance or rejection were credit ratings, character references, length of time employed, and student status. The percent of rent subsidized by government and sex of household head had little effect on applicant acceptance. Although a meaningful model for estimating the probability of eviction could not be developed, low eviction rates resulting from the tenant selection model suggest that it may serve as a reasonable proxy.  相似文献

Africa is the world’s biggest battleground in the fight against hunger. African governments and the international development community have increasingly focused on finding ways and means to end hunger and ensure the right and access to food for the continent’s burgeoning population. Public spending on agriculture is one such measure. This study examines the role government spending on agriculture has played in enhancing the state of Africa’s food security over the past 25 years. We examine the existing relationship between the two, whether this relationship varies over time and space, and whether it depends on the amount spent. We explore various aspects of food security and check whether spending on research and development follows the same patterns as the overall public agricultural spending. We find some evidence of significant beneficial effects of public agricultural spending on food security but only for the countries which allocate greater proportions of their budgets to agriculture. Spending on agricultural research and development also shows a positive impact on Africa’s food security. There also exists some evidence supporting the temporal effects of public spending. We consider that the Maputo Declaration commitment to allocate at least 10% of public spending to agriculture pertinent.  相似文献

The risk-return trade-off in human capital investment   总被引:6,自引:0,他引:6  
In this paper, we analyze investments in human capital in a way which is standard for financial assets, but not (yet) for human capital assets. We study mean-variance plots of human capital assets. We compare the properties of human capital returns using a performance measure and by using tests for mean-variance spanning. Fields differ strongly not only in common rates of return, but also in return per unit of risk. We identify a range of educations that are efficient in terms of investment goods, and a range of educations that may be chosen for consumption purposes.  相似文献

This paper provides an empirical analysis of the impact of consumer learning over time on the demand for Japanese cars, using both a multinomial logit demand model and the Berry–Levinsohn–Pakes demand model ( Econometrica , vol. 63, 1995, 841–90). The data suggest that learning about particular models, manufacturers, and Japanese cars as a group had a positive impact on the demand for individual models during the 1970s and 1980s.  相似文献

Single parents and unmarried couples are increasingly replacing the traditional nuclear family. This paper investigates if the greater variety in living arrangements contributes to increased resource disparities among children in Germany. Children in single parent families are disadvantaged in at least three dimensions decisive for their later achievements: material standard of living, parental education, and parental childcare time. We compute multidimensional inequality and poverty indices using SOEP data from 1991 to 2012. We distinguish between parental and publicly provided childcare, which is an increasingly important in‐kind benefit in Germany. We find that both multidimensional inequality and poverty declined as expanded public childcare strongly reduces resource disparities among children.  相似文献

While innovators may rush to purchase many new products, most consumers are more conservative and do not want to buy into fads but purchase only those new products that are viable. How do the majority of consumers make judgments about whether they will adopt an innovation? This article examines the evaluative aspects of adoption as a means for better understanding consumer adoption and the market factors that may influence the success of an innovation. This research introduces a conceptual model that shows how consumers’ evaluation of product category attractiveness affects the adoption decision for really new products. These consumer evaluations are based on the attributes of the product category (“extrabrand” attributes) rather than brand attributes. Results from a test of the model indicate that consumers do use extrabrand attributes to assess the attractiveness of innovative new products.  相似文献

This Dialogue presents the views of four authors, from the US, the UK, and Norway, on the best policies to help lone mothers. Lone mothers face an inevitable dilemma in allocating their time between earning income and caring for their children. The low-earning capacity of women in an unequal labor market exacerbates the problem, causing material hardship for many lone mothers and their families. The policy solutions proposed lie along a spectrum, ranging from those that seek to enable all lone mothers to take employment to those that aim to let mothers choose whether to take employment or care for their children themselves. Other policies discussed concern ways to value and support caregiving, improve the low-wage labor market for women, and provide a set of income supports that would both boost income and provide time to care for children.  相似文献

Osteopetrosis     
This case study describes the fairly rare entity of osteopetrosis and points out how a seemingly insignificant "anemia" can, on thorough investigation, be found to be a very significant disease with a poor prognosis.  相似文献

Research on industry evolution highlights the role of knowledge-building activities of startups and established firms in shaping knowledge evolution in a nascent industry. Yet, research thus far has overlooked the possibility that differences between startups and established firms might also shape the diffusion of the knowledge that they build. This study abductively explores this conjecture in the context of solar energy by examining the extent to which the photovoltaic cell inventions that firms create spur subsequent inventions by other firms. In contrast with existing literature highlighting differences across firms in the types of inventions they create, this study reveals asymmetries between startups and established firms in the diffusion of the knowledge underlying their inventions, even when they create inventions with similar attributes.  相似文献
