Jonathan P. Beauchamp David Cesarini Magnus Johannesson 《Journal of Risk and Uncertainty》2017,54(3):203-237
We examine the psychometric and empirical properties of some commonly used survey-based measures of risk preferences in a population-based sample of 11,000 twins. Using a model that provides a general framework for making inferences about the component of measured risk attitudes that is not due to measurement error, we show that measurement-error adjustment leads to substantially larger estimates of the predictive power of risk attitudes, of the size of the gender gap, and of the magnitude of the sibling correlation. Risk attitudes are predictive of investment decisions, entrepreneurship, and drinking and smoking behaviors; are robustly associated with cognitive ability and personality; and our estimates are often larger than those in the literature. Our results highlight the importance of adjusting for measurement error across a wide range of empirical settings. 相似文献

In this paper we compare several types of economic dependency ratios for a selection of European countries. These dependency ratios take into account not only the demographic structure of the population, but also the differences in age-specific economic behaviour such as labour market activity, income and consumption as well as age-specific public transfers. In selected simulations where we combine patterns of age-specific economic behaviour and transfers with population projections, we show that in all countries population ageing would lead to a pronounced increase in dependency ratios if present age-specific patterns were not to change. Our analysis of cross-country differences in economic dependency demonstrates that these differences are driven by both differences in age-specific economic behaviour and in the age composition of the populations. The choice of which dependency ratio to use in a specific policy context is determined by the nature of the question to be answered. The comparison of our various dependency ratios across countries gives insights into which strategies might be effective in mitigating the expected increase in economic dependency due to demographic change. 相似文献

Estimates of adult mortality in countries with limited vital registration (e.g., sub-Saharan Africa) are often derived from information about the survival of a respondent’s siblings. We evaluated the completeness and accuracy of such data through a record linkage study conducted in Bandafassi, located in southeastern Senegal. We linked at the individual level retrospective siblings’ survival histories (SSH) reported by female respondents (n = 268) to prospective mortality data and genealogies collected through a health and demographic surveillance system (HDSS). Respondents often reported inaccurate lists of siblings. Additions to these lists were uncommon, but omissions were frequent: respondents omitted 3.8 % of their live sisters, 9.1 % of their deceased sisters, and 16.6 % of their sisters who had migrated out of the DSS area. Respondents underestimated the age at death of the siblings they reported during the interview, particularly among siblings who had died at older ages (≥45 years). Restricting SSH data to person-years and events having occurred during a recent reference period reduced list errors but not age and date errors. Overall, SSH data led to a 20 % underestimate of 45 q 15 relative to HDSS data. Our study suggests new quality improvement strategies for SSH data and demonstrates the potential use of HDSS data for the validation of “unconventional” demographic techniques. 相似文献

Lawns are considered monocultures and lesser contributors to sustainability than diverse nature but are still a dominating green area feature and an important cultural phenomenon in cities. Lawns have esthetical values, provide playground, are potential habitat for species, contribute to carbon sequestration and water infiltration, but also increase pesticides, fertilization, are monocultures and costly to manage at the same time. To evaluate the potential impact of lawns, whether positive or negative, it is of interest to estimate the total lawn cover in cities and its change over time. This is not a straightforward process, e.g., because many lawns are small and covered by trees. In this study we review the existing literature of lawn cover in cities and the different methodologies used for cover estimation. We found both pros and cons with NDVI and LiDAR data as well as manually interpreted aerial photos. The total cover of lawns in three case study cities was estimated to 22.5%. By extrapolating these percentages to all Swedish cities lawn cover was estimated to 2589 km2 (0.6% of the terrestrial surface). The approximated total municipal management cost of lawns in all Swedish cities was 910,000,000 USD/ year. During 50 years lawn area almost doubled in relative cover and 56% of them were continuously managed. Since lawns constitute large parts of the urban greenery and are costly to manage it is highly relevant to consider their social, ecological and cultural value compared to alternatives, e.g., meadows with less intensive management. 相似文献

We examine the relationship between different aspects of human development and Hofstede’s six dimensions of national culture. Using multivariate regression and canonical correlation analysis, we show that all the dimensions of national culture except masculinity have a significant impact on human development, and that the overall strength of the association between the two groups of variables is a high positive one. In general, the direction of the influence of the national culture variables on economic growth differs from the manner they influence other variables, which reinforces the fact that economic growth does not always translate into true people-centred development. Furthermore, the national culture dimensions do not explain much of the variation in a number of health indicators. 相似文献

This study explores the financial costs, time involved in migration and benefits at household level. A household survey has been conducted to investigate about characteristics of migrants, transaction costs and sources of financing by which overseas migration is financed. Results of PSM technique explored that overseas migration conveys worthwhile benefits as measured by their total expenditures, food expenditures, non-food expenditures, clothing expenditures, expenditures on pots and pans, expenditures on vehicles and saving levels. Establishment of technical training institutions, creation of micro-finance institutions and enhancing their functioning as well as sensitization about ‘Pakistan Remittance Initiative’ would be some of the policy options in order to tackle with the problem. 相似文献

Recently C. Czymara and A. Schmidt-Catran published in this journal (KZfSS 2016 (2)) a factorial Survey-Experiment to contribute to the current debate on the inflow of refugees in Germany. The authors concluded from their Survey-Experiment that in particular highly qualified immigrants who show little culture distance should get accepted in Germany, while for instance Muslim immigrants would be more strongly rejected. In this comment it is argued that authors’ results probably suffered from a strong confounder bias. The employed experimental design also allows for a lot of alternative interpretations. Therefore, readers of the original article or further users of the data should be more cautious when interpreting the results. 相似文献

This article offers a new definition of military cultural competence based on a review of the literature. As a starting point, the defining characteristics of military culture is discussed and includes the chain of command, military norms, and military identity. Having laid this groundwork, the multidimensionality of military cultural competence—attitudinal, cognitive, behavior—is discussed. Clinical applications of these various competencies are provided. 相似文献

Parenting is a critical factor in substance abuse prevention. Positive parenting behaviors are identified as a protective factor for substance abuse among youth. Limited research exists that investigates the role of parenting practices on minority youth substance use. The present study seeks to examine correlates between parenting and recent alcohol use among African American youth. Specifically, to what extent do African American students report experiencing specific parenting behaviors that are measured by the National Household Survey on Drug Use and Health?, do specific parenting behaviors increase the risk of recent alcohol use among African American youth?, does the impact of parenting behaviors on recent alcohol use among African American youth differ based on sex (males and females) and age category (12–13, 14–15, and 16–17 years old) were examined in this study? Logistic regression analysis of the National Household Survey on Drug Use and Health was conducted to examine the research questions. Findings indicated that parenting behaviors was associated with recent alcohol among youth. Significant differences were found for males, females, 12–13, 14–15, and 16–17 years olds. Study findings demonstrate the importance of positive parenting behaviors in youth alcohol prevention. Program specialists may target parenting as a means of preventing and reducing youth alcohol use among African American youth. 相似文献

The social economy (SE) is alternatively conceptualized as a third sector (between the private and public sector); or by a typology of the organizations involved (such as cooperatives, non-profit organizations and social enterprises); or by the principles and values driving such activities (such as cooperation, mutual benefit, and democracy). One important consideration is often overlooked, namely that the SE emerges in different forms and with varied emphases depending on location. The SE is ‘place-based’—rooted in specific geographic, historical, cultural, and socioeconomic settings. This article explores the conceptualization of the SE in the Bolivian context from the perspective of government and civil society actors. The research took place after the country recognized the importance of the social, cooperative and community economy in their new constitution and found that the understanding of the SE in Bolivia relates strongly to the country’s indigenous and colonial heritage. 相似文献
