This paper proposes a particular methodology to render budget data more comparable over highly diverse regions. More specifically, a set of regional poverty lines will be derived and employed as deflators to correct household expenditures for spatial differences in prices and needs. The quality of these deflators depends on the extent to which the underlying poverty lines adhere to the principles of consistency and specificity. Central to reconciling both principles in practice is our pursuit for austerity in setting poverty thresholds as well as the view that differences in social norms mainly reflect differences in social inclusion needs. The particularity of the proposed method compared to standard practice lies in the combination of: (i) the pronounced subdivision in socio‐economic strata; (ii) the use of a differential calorie threshold per sector; (iii) the introduction of protein intake; (iv) the derivation of a minimal house rent; and (v) the use of an austere non‐food/non‐housing allowance. The impact of this method is illustrated using a budget survey of the Democratic Republic of Congo.  相似文献

A lot of research on income mobility and income inequality is based on survey questions about income. Various question formats are being used. Researchers seem to assume that the actual format used delivers the best estimate of the “true” income. However, surprisingly little empirical support is available for this claim. We implemented an experimental design using the short and long versions of income questions in a Hungarian survey. Results show an overall positive difference between the long and short version. The differences are related to the income components (wages and salaries, transfers, and assets), and respondent characteristics, controlling for the effect of the order of the two versions of income questions. Based on the results, we provide some recommendations for implementing income questions in surveys.  相似文献

Open innovation is increasingly popular among practitioners and scholars, but its implications for public policy making have not yet been analysed in detail. This paper explores a theoretical framework to structure the debate about public policy making that facilitates open innovation. We first define open innovation in terms of firms’ open innovation practices and external conditions that encourage enterprises to practice open innovation. We show that policies for open innovation are legitimate as traditional arguments like market and system failures continue to apply. Next, we identify several guidelines for policymaking. Rather than just offering R&D and interaction-oriented policies, we conclude that open innovation warrants attention in a broader range of policy areas, including entrepreneurship, education, science, labour markets and competition. Developing truly horizontal policies is a major challenge to facilitate open innovation in developed economies.  相似文献

Markets for natural resource futures contracts and cash forward contracts experience a rapid growth. According to theory, this should result in more efficient resource depletion, implying that price formation is more consistent with Hotelling's rule. The rationale of this stabilization effect is briefly discussed. Next, we analyze the impact of expanding futures markets on the behaviour of individual resource owners trading on the cash market. Using a simple pulse extraction model, we demonstrate that the expected time of depletion can shift to the present or the future, and that utility of exploitation can go up or down, as market prices are stabilized.  相似文献

Youth violence continues to be a serious and too prevalent problem in the United States. There is increasingly compelling evidence that the exceptionally high levels of mortality are linked to access to guns by youth. There is also evidence that youth violence occurs in multiple forms and that these differing forms call for different prevention strategies. Some youth violence is situational, some is best understood within its relationship context, some occurs as part of a predatory criminal activity, and some seems to be the result of serious psychopathology. This paper provides a review of the current understanding of the epidemiology of youth violence in the United States, applies a developmental-ecological perspective to risk, reviews the empirical support for differing prevention approaches, and suggests practice, research, and policy implications of this knowledge base.  相似文献

This study examines the effect of uncertainty on governance mode choice of interfirm relationships in new business development (NBD). We combine transaction cost economics and real options reasoning, arguing that in the early stages of NBD, where technological and market uncertainty are very high, companies are better off using governance modes that are reversible and involve a low level of commitment. When uncertainty has decreased as a result of prior R&D investments, transaction costs considerations become dominant and companies will shift towards governance modes that are less reversible and more hierarchical. We argue that technological distance leads to less hierarchical governance modes and prior cooperation between firms leads to subsequent choices for more hierarchical modes. Finally, we propose that higher exogenous uncertainty leads to less hierarchical governance modes.  相似文献

The expansion of health insurance in emerging countries raises concerns about the unintended negative effects of health insurance on labour supply. This article examines the labour supply effects of the Health Care Fund for the Poor (HCFP) in Vietnam in terms of the number of work hours per month and labour force participation (the probability of employment). Employing various matching methods combined with a Difference-in-Differences approach on the Vietnam Household Living Standard Surveys 2002–2006, we show that the HCFP, which aims to provide poor people and disadvantaged minority groups with free health insurance, has a negative effect on labour supply. This is manifested in both the average number of hours worked per month and the probability of employment, suggesting the income effect of the HCFP. Interestingly, the effects are mainly driven by the non-poor recipients living in rural areas, raising the question of the targeting strategy of the programme.  相似文献

Injury is the leading cause of death for children 0- 19 years of age in Europe, accounting for 3.1 deaths per 10 000 children per year. The youngest children of the ages 0-4 years require the most protection in this age group, with 2.5 injury-related deaths per 10 000 children in Europe annually. As parents are the primary caregivers of children, it is necessary to learn more about parents' perceptions, attitudes and behaviours towards child safety. This study presents the findings of a 14-country study in Europe on this theme. A quantitative survey of parents of children aged 5 years or under was performed in 14 EU member states in order to enable better targeting of prevention efforts aimed at educating parents. The total sample size was 2088. The results show that 95% of parents reported that they personally take measures to avoid accidental injury to their children. Their top concern with regard to safety of their children was children being hit by a car. The most common response, when asked why some parents find it difficult to protect their children from accidental injury, was not being able to watch their children constantly. Lack of awareness or knowledge about the causes of accidents was the second response. Two-thirds of parents would like to see more help from the government to prevent childhood injuries. Three-quarters of parents agreed that child injuries can be avoided. It was concluded that parents want to be better informed about the causes of child accidents and about actions they and society can take to reduce injury-related risks to children.  相似文献

This paper investigates the importance of transport costs in new venture internationalisation, i.e. of firms that start exporting before they are 3 years of age. It does so by merging two large international datasets, on the firm level (covering 49,584 firms) as well as on the country level (covering 154 countries). It is found that transport costs matter significantly for new venture internationalisation, for older firms’ decision to export, as well as the extent of the latter’s subsequent exports. Export costs, the quality of transport infrastructure and domestic logistics costs affect new venture internationalisation even when controlling for a range of standard determinants. New international ventures behave differently from older firms in two important ways: (1) Transport costs affect the probability that they will export but not the extent of their subsequent exports and (2) their probability of exporting is affected negatively by their networking, domestic success and ISO status, whilst in the case of older firms, these factors have a positive impact. Various recommendations for policy and further research are made.  相似文献
