此次专题承接第10期上海当代艺术博览会讲座系列,继续发表来自古奥德莫克·美迪那,玛莎·罗斯勒,卢迎华,彦·沃尔沃特以及汉斯·乌尔里希·奥布里斯特四位批评家的文章。四篇文章分别从不同的侧面继续了关于当代性的讨论。古奥德莫克·美迪那以论纲的形式,从不同方面列举了当代艺术发展中的十一个特性;玛莎·罗斯勒以美国当代艺术发展的状况为例,探讨了当代艺术何以仍然具有政治批判性及社会批判性;而卢迎华则从回顾关于中国当代艺术本土化的讨论出发,特别引用了栗宪庭与费大为的通信,表达了对于中国当代艺术在未来的发展中必须确立自身原则,积极主动的诉求;彦·沃尔沃特则以某种类似自白的方式,略带意识流的手法表达了自己关于当代的惶然与期待;汉斯·奥布里斯特用独特的碎片形式,向我们展示了他近期关于创新及双/三年展的思考。 相似文献

If surveys offer two different measurements of household income, one can use them simultaneously to identify the potential effects of measurement error on the observed-income mobility of the poor. In this paper we investigate transition tables between subsequent income states. Latent Markov models are used to model incorrect classifications of income states. Misclassifications are interpreted as measurement error or spurious changes that are not consistent with a simple transition table model. The empirical results for the German Socio-Economic Panel (GSOEP) show that the observed transition tables overestimate the mobility between poverty states. 相似文献

Recently, several undesirable feature of classical risk measure like variance or value-at-risk have been mentioned in the literature. Due to this drawbacks, alternative risk measures as the lower partial moments receive increasing attention. The present paper analyzes the lower partial moments with respect to their compatibility to expected utility theory as well as their psychological plausibility. With respect to the latter point, shortfall expectation seems to be more realistic than the other lower partial moments. We proceed by analyzing demand for coinsurance in the context of risk measurement by shortfall expectation. 相似文献

Using an experimental design of stating equivalent probabilities for 252 stimulus lottery pairs, Chechile and Cooke (1997) alleged to have refuted generic-utility theory which itself comprises many modern utility theories. The present paper systematically investigates the feasibility of the Chechile-Cooke experimental design using numerical methods. We examine 1,277 utility setups (involving 17 parameter sets for four probability-weighting functions and 11 parameter sets for three component utility functions) which represent ten different utility theories. Our results demonstrate that on average for more than one third of all stimulus lottery pairs no equivalent probabilities exist. That is, the Chechile-Cooke experimental design prevents subjects from stating their true probability equivalents. Therefore, they cannot claim to have refuted generic-utility theory and the members of its family.This paper was submitted to theJournal of Risk and Uncertainty on January 14, 1999. It was, however, rejected on April 16, 1999. 相似文献

Since Mao’s death China has greatly strengthened its contacts with Western industrialized states. This year the People’s Republic has concluded trade agreements with Japan and the European Community, amongst others. All these activities suggest that China’s economic policy is set on a new course. 相似文献

In this paper, we examine empirically the predictions of a range of theoretical models which give a prominent role to technology shocks in explaining business cycles. To this end, we estimate (4-digit SIC) industry-level VAR models for US manufacturing using real output, the real wage and utilization corrected measures of technology and labor input. Our results support both sticky-wage DGE and RBC models over sticky-price DGE models. Moreover, they cast some doubt on the importance of technology shocks as propulsive mechanism for business cycles at the industry level. 相似文献

This paper gives a deeper insight into consumer preferences for different food products of varying place of origin (i.e. local, Germany, neighboring country, non‐EU country) and production practices (i.e. organic vs. non‐organic). Consumer surveys combined with choice experiments were conducted with 641 consumers in eight German regions. Mixed logit models were estimated to draw conclusions on consumers’ preferences for different product attributes. The Stimulus‐Organism‐Response model was applied to theoretically frame the key findings. Results reveal that consumers prefer locally produced food to organic food. However, conclusions on consumers’ preferences should not be generalized as they vary depending on product type and consumers’ place of residence. When looking at the willingness‐to‐pay estimates for ‘organic’ and ‘local’ while distinguishing among consumers from different regions of Germany, results indicate that consumers living in rural areas and consumers living in the eastern part of Germany are less willing to pay a premium for organic products than urban consumers and consumers from other parts of Germany. As preferences for origin attributes and organic production vary between different food products and in different regions of Germany, market actors should design marketing activities accordingly. This study adds to the international research on consumers’ preferences for organic and/or local food. The results provide better insights into preference structures, as more than one product has been included and surveys were conducted in different regions across Germany. 相似文献
