Markets for cash‐crops in developing countries are typically characterized by a concentration of buyer power at different levels of the supply chain. For instance, small‐scale coffee farmers sell their produce to a middleman, who in turn sells the coffee onward to an exporter, often a foreign multinational, with monopsony power in the hands of the purchasers at both levels. We analyze pricing behavior and welfare with different assumptions regarding market power. In particular, we show that a more powerful exporter is likely to benefit the producers and may even lead to higher welfare for the producer country as a whole.  相似文献

We investigate the funding modes of German banks and the implications for lending and profitability during 1992–2002. We find that at many banks, deposits from customers decrease in relative terms while interbank liabilities increase as a source of funding. We cannot detect a negative impact of the relative decline in deposits on lending. The decreasing ability of banks to collect deposits and the substitution of deposits by interbank liabilities unfavorably affects the net interest result of banks that exhibit a deposit deficit, especially savings banks. Our findings indicate a structural lengthening of the intermediation chain, which has broader implications for the functioning and stability of the financial system.  相似文献

To a large extent there exists a gap between European and American management research reflecting the differences between nomothetic and idiographic research approaches. The paper investigates the logic used by North American reviewers when evaluating European papers based on an idiographic case study approach. Our analysis enables us to uncover the criteria used by North American reviewers and to relate them to the criteria suggested for idiographic research. We also discuss the role of writing style and structure in the North American reviewers' assessment of idiographic papers. Based on our analysis we make suggestions to editors, reviewers, and authors of idiographic papers, in order to enhance the probability for publication of idiographic, qualitative and processual research and thus to bridge the transatlantic gap.  相似文献

This paper uses Canada's National Longitudinal Survey of Children and Youth to examine whether greater cash transfers available to parents with disabilities when their child was aged 5 to 15 increase the chances that the child will attend postsecondary education (PSE) as a young adult. We exploit differences across provinces and over time in the generosity of provincial disability benefits programs in Canada and find that higher disability benefits when the child was aged 5 to 15 years increase the probability that he or she will have attended or be attending PSE by age 19 to 25. The estimated effect size increases with the severity of the parental disability and the number of disabled parents. Because lower disability benefits significantly worsen performance of public school aged children on standardized math tests and elevate anxiety symptoms, one plausible pathway from disability benefit levels to PSE attendance may be through the cognitive and non‐cognitive skills children acquire by the age of 15. We conclude that the level of disability transfers available early in a child's life mitigates the impact of having a parent with a disability as a source of inequality of opportunity and of unequal probability of PSE participation.  相似文献

Young workers in the 1990s can expect greater economic insecurity, as well as lower average earnings, compared to older workers, or compared to the youth of previous decades. The cost of greater insecurity depends upon an individual's probability of unemployment, marginal utility of income gains/losses and the extent to which individuals can smooth consumption over time by borrowing and drawing down assets. Since unemployment insurance cutbacks and higher unemployment have increased the risk exposure of youth, changes in the expected value of their income may understate utility losses as measured by the change in certainty equivalent income.
This paper uses a behavioural microsimulation model to compare the impacts of 1971 and 1994 unemployment insurance legislation and unemployment rates in Canada. It calculates both the expected value of income changes and, using a Stone-Geary utility function, the change in inequality of well-being (as measured by certainty equivalent income) for youth and for prime age workers. Both calculations reveal that youth were disproportionately affected by Canada's changing labour market environment. Very few youth have enough assets to finance consumption during spells of unemployment.  相似文献

In this paper, we investigate the problem of finding housing for refugees once they have been granted asylum. In particular, we demonstrate that market design can play an important role in a partial solution to the problem. More specifically, we investigate a specific matching system, and we propose an easy-to-implement mechanism that finds an efficient, stable, and maximum matching. Such a matching guarantees that housing is efficiently provided to a maximum number of refugees, and that no refugee prefers another specific landlord to their current match when, at the same time, that specific landlord prefers that refugee to their own current match.  相似文献

The partial correlation is a commonly used measure for assessing the bivariate correlation of two quantitative variables after eliminating the influence of one or more other variables. The partial correlation is generally interpreted as the correlation that would result if the variables to be eliminated were fixed (not allowed to vary and influence the other variables), which is referred to in the statistical literature as conditional correlation. The present paper demonstrates, by means of theoretical derivations and practical examples, that when the assumption of multivariate normality is violated (e.g., as a result of nonlinear relationships among the variables investigated) the usual interpretation of the partial correlation coefficient will be basically incorrect. In extreme cases the value of the partial correlation coefficient may be strongly positive, close to 1, whereas the conditional correlation may have a large negative value. To solve this problem the paper suggests to partial out a certain function (in most cases the square) of the variables whose effects are to be eliminated if nonlinear relationships are likely to occur.  相似文献
