The study analyses potential scale efficiencies of 1196 Dutch fundraising charities for 2005–2009. The data set includes a unique group of small charities (reporting an income of less than €1 million). The study articulates and tests differences in financial efficiency between smaller and larger charities, specifically concerning program expenditure, administrative expenditure, and fundraising expenditure. The study finds that reported levels of program-spending efficiency and administrative efficiency are similar across small and large charities, with no economies of scale. In addition, the study finds that smaller charities report considerably better fundraising efficiency ratios, with the smallest charities reporting an average spend of €8 to raise €100 and the largest charities reporting an average spend of €15. The paper discusses why larger charities appear to experience scale inefficiencies in fundraising and provides directions for further research.  相似文献

We demonstrate how an evolutionary agent-based model can be used to evaluate climate policies that take the heterogeneity of strategies of individual agents into account. An essential feature of the model is that the fitness of an economic strategy is determined by the relative welfare of the associated agent as compared to its immediate neighbors in a social network. This enables the study of policies that affect relative positions of individuals. We formulate two innovative climate policies, namely a prize, altering directly relative welfare, and advertisement, which influences the social network of interactions. The policies are illustrated using a simple model of global warming where a resource with a negative environmental impact—fossil energy—can be replaced by an environmentally neutral yet less cost-effective alternative, namely renewable energy. It is shown that the general approach enlarges the scope of economic policy analysis.  相似文献

We investigate the Hartwick rule for saving of a nation necessary to sustain a constant level of private consumption for a small open economy with an exhaustible stock of natural resources. The amount by which a country saves and invests less than the marginal resource rents equals the expected capital gains on reserves of natural resources plus the expected increase in interest income on net foreign assets plus the expected fall in the cost of resource extraction due to expected improvements in extraction technology. Effectively, depletion is then postponed until better times. This suggests that it is not necessarily sub-optimal for resource-rich countries to have negative genuine saving. However, in countries with different groups with imperfectly defined property rights on natural resources, political distortions induce faster resource depletion than suggested by the Hotelling rule. Fractionalised societies with imperfect property rights build up more foreign assets than their marginal resource rents, but in the long run accumulate less foreign assets than homogenous societies. Hence, such societies end up with lower sustainable consumption and are worse off, especially if seepage is strong, the number of rival groups is large and the country does not enjoy much monopoly power on the resource market. Genuine saving is zero in such societies. However, World Bank genuine saving figures based on market rather than accounting prices will be negative, albeit less so in more fractionalised societies with less secure property rights.  相似文献

To meet the challenges of an ageing population, eligibility ages for state pensions have increased, early retirement arrangements have been abolished, and a substantial part of the risk and responsibility for an adequate standard of living after retirement has been shifted from the government, employers and pension funds to individuals and private households. Consequently, policy makers have become more concerned with whether individuals are able to make pension-related decisions that are in their own best interest.  相似文献

This article examines the effects of time preferences on job search behaviour and tests the exponential versus the hyperbolic discounting model. Theoretically, the relations between time preferences and job search intensity, reservation wages and the exit rate depend on whether exponential or hyperbolic discounting is assumed. By analysing these relations empirically we test which model of intertemporal choice better explains the results. Using the DNB Household Survey, a Dutch longitudinal survey, we capture variation in time preferences by a psychological construct that measures an individual’s future orientation. The empirical results are consistent with the hyperbolic discounting model.  相似文献

Like many other countries, the Netherlands is experiencing a sharp rise in the ageing population. As age increases, people’s mobility may decrease. However, older people have more leisure time compared to their younger (working) counterparts, and potentially spend more time on social activities. Therefore, this group can possibly increase social travel demand. However, to date, the travel demand for social activities of senior citizens has received only little attention. This paper studies trip-making for social purposes, with a special focus on the demographic ageing factors. Using social activity diary data, models are estimated to predict the number of social trips, the travel distance and mode of transport for social trips. The results indicate that the elderly of today seem to be as mobile as their younger counterparts with respect to the number of social trips. High education and involvement in clubs on average result in more social trips and full time work is found to result in fewer social trips. With regard to trip distance the results show that the average travel distance does not decrease as people get older. Full time work is found to result in longer social trips. Shorter trips were found for people in urban as well as rural areas. Trips for the purpose of visiting or joint activities tend to be longer than average. With regard to transport mode choice the results indicate that older seniors (75+) are less likely to choose the bicycle, relative to driving. No other significant age effects were found. Significant effects were found for gender, household structure, education level, car ownership, having a disability, urban density, distance and the purpose of the social activity.  相似文献

Existing studies on shifts in income welfare in South Africa since the demise of apartheid suggest that income inequality increased, while headcount poverty rates declined since 2000, after some evidence of an increase or no change in poverty in the 1995–2000 and 1996–2001 periods. This study provides an analysis of the shifts in non-income welfare that have occurred in South Africa between 1993 and 2004. We use factor analysis to construct an asset index as a measure of non-income-based welfare. Variables reflecting household access to a range of services and assets are used in the construction of the index. Significantly different results emerge when non-income welfare shifts are considered: we show statistically significant decreases in the headcount asset poverty rates between 1993 and 2004 across a range of covariates. Finally, asset inequality decreased significantly between 1993 and 2004 – in stark contrast to results based on consumption data.  相似文献

Where firms choose to disclose voluntary environmental information   总被引:1,自引:0,他引:1  
Corporate environmental performance is of increasing importance to investors, public policy makers and the general public. Firms disclose environmental information (mostly) voluntarily in their annual reports and on their websites. These disclosures are important, because they provide environmental performance information and influence capital markets. We compare environmental disclosure in annual reports and on websites with a long-term (bad) and a short-term (crisis) environmental performance measure. We find evidence to support our hypotheses that different levels of environmental disclosure are made in annual reports and on websites under different conditions. More specifically, firms disclose more environmental information on their websites when faced with an environmental crisis and more in their annual reports when they have a bad environmental reputation.  相似文献

An important task of auditors is to check whether recorded values are correct. From the number (or total) of the errors found in a sample, upper confidence limits for the fraction (or total) of the errors in the population are calculated by standard methods.
Even auditors are human, however, and may make mistakes: errors may remain unnoticed. As administrative rules and regulations are becoming more and more complicated, this kind of auditors' mistakes tends to occur more frequently. Hence, there is an increasing need to check the auditing process itself. This can be achieved by checking a subsample of audited values a second time, now by an error-free supervisor.
This paper investigates the consequences of the (possible) occurrence of errors in this subsample. A simple and analytically attractive model is presented for the number of errors found in this double inspection scheme. Maximum likelihood estimators are derived for the population fraction of errors and the probability of an error remaining unnoticed. Based on that, an exact upper confidence limit for the population fraction of errors is calculated, treating the probability of an unnoticed error as a nuisance parameter. Our method was originally developed during a recent Dutch case study: in a subsample of already audited values one additional error was found by the supervisor. It is shown that, as a consequence, the upper confidence limit is increased very sizeably.  相似文献
