The scientific literature stresses the importance of culture and social environment in determining what people think about alcohol consumption and consequently do. Several pieces of research have proved the influence on young adults’ alcohol use of proximal social contexts of their family and peers. The present study aimed at investigating the influence of family behaviours and norms compared to the peers’ influence in a context where the culture of alcohol is changing between the different generations. Data were collected by means of a self-report questionnaire on a sample of 598 young adults (average age 22.20 years). The variables investigated were socio-demographic characteristics, the alcohol consumption of parents and friends and the parents’ and peers’ approval of alcohol consumption. The results confirmed the role of family and friends in influencing young adults’ consumption of alcohol, stressing a difference between perceived behaviours and norms. The perceived consumption of parents and friends influenced the participants’ consumption. On the contrary, the effects of the approval of drinking were limited. Globally friends had a stronger influence on alcohol consumption in comparison with family.  相似文献

Traditional models of input demand rely upon convex and symmetric adjustment costs. However, the fortune of this highly restrictive approach is due more to analytical convenience than to empirical relevance. In this note we examine the model under more realistic hypothesis of fixed costs, show that it can be cast in the form of a Double Censored Random Effect Tobit Model, derive its likelihood function, and finally evaluate the performance of the ML estimators through a Monte Carlo experiment. The performances, although strongly dependent on the degree of censoring, appear to be promising.  相似文献

Recent literature broadly highlight the importance of modelling technological innovation effects on economic growth. This paper develops a methodology that allows to measure technology contribution to economic convergence; the choice of a regional framework also allows to underline interregional knowledge transmission as a the major channel of technological progress. Moreover, the specification of a dynamic growth model enables to evaluate both the regional convergence and the effect of innovation on long-run labour productivity without resorting to any technology index measurement. We contribute to the methodological literature also by comparing different dynamic panel data estimation procedures and by detecting both the presence of small sample bias and the existence of a nearly unit root autoregressive process in labour productivity series. The results of an empirical analysis on Italian regions show how most of innovation resources derives from relevant spillover mechanisms. Furthermore, technology spillover intensity seems to be strongly affected by geography and productive structure of regions.Financial support by Fondazione Cassa di Risparmio di Rimini and Uniturim S.p.A. is gratefully acknowledged.  相似文献

Small‐area estimation techniques have typically relied on plug‐in estimation based on models containing random area effects. More recently, regression M‐quantiles have been suggested for this purpose, thus avoiding conventional Gaussian assumptions, as well as problems associated with the specification of random effects. However, the plug‐in M‐quantile estimator for the small‐area mean can be shown to be the expected value of this mean with respect to a generally biased estimator of the small‐area cumulative distribution function of the characteristic of interest. To correct this problem, we propose a general framework for robust small‐area estimation, based on representing a small‐area estimator as a functional of a predictor of this small‐area cumulative distribution function. Key advantages of this framework are that it naturally leads to integrated estimation of small‐area means and quantiles and is not restricted to M‐quantile models. We also discuss mean squared error estimation for the resulting estimators, and demonstrate the advantages of our approach through model‐based and design‐based simulations, with the latter using economic data collected in an Australian farm survey.  相似文献

This paper examines the structure and performance of the banking industry in Jordan during the period 2000–2006. The Jordanian banking industry is free of extensive state ownership and government direction of the economy. These positive features are reflected by the absence of dominant state-owned banks and by the limited use of directed credit programs, interest rate controls, and credit ceilings. The banking industry is well developed, with bank assets representing 239.80 percent of the GDP at the end of 2006, which is a high percentage compared with other developing countries in the region.  相似文献

Abstract The mass consumption of agrochemicals, including manufactured fertilizers and pesticides, by industrialized agricultural systems worldwide threatens human health and the health of ecosystems. The production of these agricultural inputs is a highly energy‐ and capital‐intensive process, and their application contributes to a variety of direct and indirect impacts on the environment. This study is an analysis of the relationships between international trade in agricultural products and the consumption of these synthetic compounds. Using OLS regression models and data from World Bank and UNFAO, we analyze cross‐national data to examine the relationship between structural factors, such as economic development and export intensity, and both fertilizer and pesticide consumption. The findings are considered from the opposing theoretical perspectives of international political economy (IPE) and neo‐liberal modernization (NLM). The results generally support the claims of IPE and contradict those of NLM, indicating that increases in exports of agricultural products contribute to increases in fertilizer and pesticide consumption within nations. These results call into question policies that promote increased trade liberalization in agricultural products.  相似文献

A measure of human development, which is not affected by some relevant drawbacks of the commonly utilized measures, is constructed. It is a function of several attributes associated with various factors — economic, social, environmental — and also includes non-homogeneous attributes. It is non-linear in its variables, so that it includes possible interactions among the attributes. Furthermore, it takes into account public opinion about human development through a well-defined procedure of assessment elicitation. The formulation of the human development function constituting the measure is described when considering just one attribute and then several attributes, and the difference between independence and dependence in assessment is shown. Such a procedure is applied to the measurement of human development in 9 countries of the EU, by using thirteen attributes related to the economic, social and environmental fields as well as to the quality of life.  相似文献

Marital disruption and economic well-being: a comparative analysis   总被引:1,自引:0,他引:1  
Summary.  Though there is a considerable literature concerned with the economic consequences of marital breakdown, there is still substantial disagreement in terms of its magnitude. One of the major problems underlying this debate is how economic well-being is defined. We implement several measures of well-being of monetary and multidimensional nature by using data from the European Community Household Panel. Another issue in this literature concerns selection bias of divorcing couples. We tackle this issue by using a propensity score matching technique combined with a difference-in-differences estimator. Results confirm the importance of the definition of well-being. We find a strong gender bias when using monetary measures but a considerably lower bias, and for some countries non-existent, when using non-monetary indices.  相似文献
