利率下降对我国居民跨期消费选择的影响分析

利率下降对居民跨期消费选择影响存在收入效应和替代效应.由于这两种效应对居民当期消费的作用方向完全相反,因而总效应要取决于这两种效应的强弱.对于我国中低收入居民来说,利率下降对其跨期消费选择的收入效应特别明显,替代效应则趋于零,因而降患反而会减少其当期消费数量.对于我国中高收入居民来说,利率下降对其跨期消费选择的替代效应在很大程度上被收入效应所抵消了,因而降息拉动其当期消费也不明显.为了刺激居民消费,除了实施降息政策以外,还必须采取其他政策与之配合.

Organic food and the plural moralities of food provisioning

The aim of this paper is twofold. The first aim is to unfold the moral complexity of organic food consumption as part of household food provisioning. By acknowledging this complexity, and the difficulty of determining what is ‘good’ and ‘right’ in food provisioning, the idea is to allow for a better understanding of how organic food may, or may not, fit in with the various concerns of food provisioning. The second aim is to analyse how food provisioners handle this complexity so that food provisioning can proceed as an ordinary everyday activity.The paper analyses empirical material from a study of household food provisioning in Denmark. Theoretically, it draws on French pragmatic sociology as represented by the work of Boltanski and Thévenot on moral conventions and regimes of engagement. The analysis illustrates that food provisioning involves several competing sets of moral conventions and that the status of organic food in relation to these is often uncertain and contested. However, it also identifies among provisioners different strategies for handling this moral complexity in ordinary everyday life. The paper calls for some modesty in trying to change consumer behaviour in favour of organic products. Providing consumers with more information about organic food may not make it easier to determine what is ‘good’ and ‘right’ when buying food. It may only add to the complexity of food provisioning and thus to the need for compromise and pragmatism.     

论德莱塞《嘉莉妹妹》中的哲学沉思

德莱塞之重要性在于:他通过对社会犀利的观察、深切的体会,率先在其作品<嘉莉妹妹>中真实记录了时代跳动的脉搏,展示出美国社会转型时期大众社会价值观的分裂性变化.德莱塞的<嘉莉妹妹>不仅是作家对机械论哲学观的演绎与证明,同时也渗透出作家浪漫主义的理想主义者的一面以及他对新兴消费意识形态的矛盾态度,从而构成他复杂的人生哲学与潜在的动态创作观,而这些主要应归因于他对生命意义的深沉的追求与探寻.     

An Exposure Assessment of Methyl Mercury via Fish Consumption for the Japanese Population

The objective of this article was to propose an exposure assessment model to describe the relationship between fish consumption and body methyl mercury (MeHg) levels in the Japanese population. Individual MeHg intake was estimated by the summation of species-specific fish consumption multiplied by species-specific fish MeHg levels. The distribution of fish consumed by individuals and the MeHg level in each fish species were assigned based on published data from Japanese government institutions. The probability of MeHg intake for a population was accomplished through a Monte Carlo simulation by the random sampling of fish consumption and species-specific MeHg levels. Internal body MeHg levels in blood and hair were estimated using a one-compartment model. Overall, the mean value of MeHg intake for the Japanese population was estimated to be 6.76 μg/day or 0.14 μg/kg body weight per day (bw/day), while the mean value for the hair mercury level was 2.02 μg/g. Compared with the survey data that tabulated hair mercury levels in a cross-section of the Japanese population, the simulation results matched the hair mercury survey data very well for women, but somewhat underestimated for men and all of the population. This exposure assessment model is a useful attempt at further risk assessment with respect to a risk-benefit analysis.

生态消费模式:社会主义生态文明建设的必然选择

当前,伴随着经济的快速发展,我国新富群体中存在着一种"病态式消费"现象,加上西方消费主义影响,引发了诸多的社会问题。实践证明,只有树立正确的消费观念、克制消费欲望、调整消费行为,才能建立生态消费模式,才能符合社会主义生态文明的要求,实现人与自然的协调发展。     

Demand Systems Estimation With Microdata: A Censored Regression Approach

Demand systems estimation increasingly makes use of household-level microdata, mainly to measure the effects of demographic variables. Data based on these household-expenditure surveys present a major estimation problem. For any given household, many of the goods have zero consumption, implying a censored dependent variable. Techniques which do not take this censored dependent variable into account will yield biased results. We utilize a censored regression approach that is computationally simple, consistent, and asymptotically efficient. The results are then presented and compared with those obtained using an uncensored technique.
