This paper examines the effects of family size and sibling position on children's current school enrollment status in the Philippines. The theoretical framework focuses on the determinants of children's participation in alternative activities, specifically schooling, market work, and home production. This approach allows for a greater understanding of the mechanisms through which fertility, as reflected by number of siblings and sibling composition, influences children's education than would examining the determinants of schooling alone. The model is estimated using the 1983 wave of the Bicol Multipurpose Survey. The results indicate the existence of negative effects of fertility on school enrollment, which, in part, operate through work status. In addition, these effects differ according to the sibling position of the child.  相似文献

This paper focuses on empirically assessing determinants of river basin management decentralization, which is growing in popularity among water resource managers world wide. Measuring decentralization as a shift of decision-making responsibility to water users or governments at the river basin level or below, the analysis sheds light on the decentralization reform process and its success, using primary data from 83 river basins world wide. Contrary to common perception that primarily emergency situations trigger reform, persistent water scarcity is found to be a major stimulus to reform. Similarly, financially well-endowed or -developed basins do not necessarily outperform poor and underdeveloped basins. Conditions improving decentralization performance include: existence of dispute resolution mechanisms; greater financial responsibility of users; and as opposed to traditional thinking, government financial support to basin budget.  相似文献

We study a principal–agent model in which the agent is boundedly rational in his ability to understand the principal's decision rule. The principal wishes to elicit an agent's true profile so as to determine whether or not to grant him a certain request. The principal designs a questionnaire and commits himself to accepting certain responses. In designing such a questionnaire, the principal takes into account the bounded rationality of the agent and wishes to reduce the success probability of a dishonest agent who is trying to game the system. It is shown that the principal can construct a sufficiently complex questionnaire that will allow him to respond optimally to agents who tell the truth and at the same time to almost eliminate the probability that a dishonest agent will succeed in cheating.  相似文献

Agents who employ non‐rational choice procedures are often vulnerable to exploitation, in the sense that a profit‐seeking trader can offer them a harmful transaction which they will nevertheless accept. We examine the vulnerability of a procedure for deciding whether to buy a lottery: observe another agent who already bought it and buy the lottery if that agent's experience was positive. We show that the exploitation of such agents can be embedded in an inter‐temporal market mechanism, in the form of speculative trade in an asset of no intrinsic value. (JEL: D84)  相似文献

The random effects in a gamma process are introduced in terms of its scale parameter. However, the scale parameter affects both its mean and variance. Hence, the variation of the degradation rates and the within degradation increments are expected to be large. For some products, the random effects affect just the rate or just the volatility of the process. Thus, two modifications of the parameters' structure of the gamma process are proposed. One implies that the random effects affect just the volatility and the second just the rate. A Bayesian estimation approach is provided and implemented in two case studies.  相似文献

There are two principal theoretical schools that seek to explain status outcomes in early adulthood: those focusing on intergenerational transmission of class privilege and those emphasizing individual characteristics, particularly ambition. The first may be called the structuralist school and the second the psycho‐social school, following the Wisconsin Model of Status Attainment. A second structuralist perspective, Segmented Assimilation, highlights transmission of socio‐economic status across immigrant generations, but emphasizes the positive role of co‐ethnic resources for upward mobility and preventing downward assimilation. We examine these alternative predictions using a large longitudinal sample of youths in Spain that includes both children of native parentage and children of immigrants. Spain possesses characteristics that make it uniquely suitable to examine these predictions. Results show that both family socio‐economic status and ambition, measured by adolescent educational aspirations and expectations, play important roles in educational and occupational attainment, but the influence of family status persists even after controlling for ambition. The influence of co‐ethnic nationalities disappears after these controls, except among Chinese and Filipino youths, a result consistent with segmented assimilation. Predictive models of status attainment yield identical results for children of immigrants and children of natives, indicating that in Spain, they have become part of a common youth universe. Theoretical and practical implications of the analysis are discussed.  相似文献

Sexual arousal is frequently characterized by both subjective (i.e., mental) and physiological (e.g., genital) components. The nuances of these components, however, are difficult to capture via self-report instruments. Asking women to describe sexual arousal in their own words may therefore enhance our understanding of this construct. In the present study, women with (n = 190) and without (n = 610) arousal concerns were recruited online and wrote about their experience of sexual arousal. Seven clusters of words were extracted using automated text analysis, and the prominence of these clusters was compared between groups of women. The autonomic arousal cluster differed between groups such that women with arousal concerns invoked this cluster significantly less than did women with no such concerns. Furthermore, the context cluster significantly predicted group membership (odds ratio [OR] = 1.063); greater scores on this cluster were associated with arousal concerns. Results suggest that autonomic arousal and relationship factors may play important roles in arousal concerns. It is suggested that clinicians assess for aspects of the sexual relationship that may facilitate or hinder sexual arousal. Clinicians may also consider inquiring about the presence or appraisal of autonomic arousal (e.g., one’s interpretation of an increase in heart rate or respiration) during sexual activity.  相似文献

This article replicated and extended Harriet Presser's (2000) investigation of the linkages between nonstandard work and marital instability. We reexplored this question using data from a sample of 2,893 newlywed couples from the National Longitudinal Survey of Youth (NLSY) and using different analytic techniques. In contrast to Presser, we found that the key dimension of husbands' and wives' employment was nonemployment. Similar to Presser, we found that wives' working of fixed night shifts increased the risk of divorce, driven by the experience in marriages over 5 years in duration. However, we did not replicate Presser's finding that the effect is significant only among households with children; rather, wives' fixed night shifts were associated with divorce only among those without children.  相似文献

This introduction explores reasons for the continuing debate on the subject of transnationalism and persistent scepticism about the significance of the topic. The basis for such disagreements has to do less with the actual existence of the phenomenon than with methodological shortcomings that led to its overestimation in the early literature and the conceptual failure to distinguish between cross‐border activities conducted by major institutions and by private actors in civil society. I explore these various problems seeking to clarify the actual scope of the phenomenon of transnationalism and its novel character. Despite recent findings that point to limited numerical involvement of immigrant groups in transnational activities, the latter remain significant because of their prospective growth and their impact on both immigrant adaptation in receiving countries and the development prospects of sending nations and communities. The evidence presented in the following articles document in detail these various aspects and indicates the multiple forms adopted by this phenomenon among immigrant groups in Europe and the United States.  相似文献
