Economics is not simply about representing reality; it is also about shaping it, an approach encapsulated in Donald MacKenzie’s aphorism that economics is best conceived as an “engine, not as a camera” (MacKenzie and Millo (Am J Sociol 109(1):107–145, 2003). The making and application of economic theories and models contribute actively and intentionally towards the making of our social world, by encouraging, guiding and legitimizing actions and decisions, or discouraging others, and by steering them in certain directions. It follows that economists do not simply draw maps of the economic territory within their compass: they are not straightforwardly the cartographers of the economy, and cannot be seen as the disinterested observers that they commonly represent themselves to be, and indeed are often thought of as. Their theoretical work has or aims at practical consequences for the economy, and indeed for society at large, and their interests and influence are thus by no means confined to academia alone. This article calls for a discussion of the ethical responsibilities of economists, and of economics, and challenges the discipline properly to assume those responsibilities; and it concludes by considering the key questions—what makes a ‘good’ economic model; and what criteria should be used to distinguish the good models, and the ‘good ways’ of handling models and their results, from the bad ones. As far as epistemology, the methodology of research programmes and the relation of theory and (social) practice are concerned, the insights of mainly von Hayek (Br J Philos Sci 6(23):209–225, 1955, The pretence of knowledge. Lecture to the memory of Alfred Nobel, 1974; Individualism and economic order, University of Chicago Press, Chicago, pp 33–56, 1980a; Individualism and economic order, University of Chicago Press, Chicago, pp 57–76, 1980b; The theory of complex phenomena. Readings in the philosophy of social science, MIT Press, Cambridge, 1994) and Popper (e.g. The myth of the framework: in defence of science and rationality, Routledge, New York 1994a; Models, instruments, and truth. The status of the rationality principle in the social sciences, pp 154–184, 1994b) provide the background of my discussion of the mentioned issues. 相似文献

Several studies using different methods have found that pornography consumption is associated with lower sexual satisfaction. The language used by media-effects scholars in discussions of this association implies an expectation that lowered satisfaction is primarily due to frequent—but not infrequent—consumption. Actual analyses, however, have assumed linearity. Linear analyses presuppose that for each increase in the frequency of pornography consumption there is a correspondingly equivalent decrease in sexual satisfaction. The present brief report explored the possibility that the association is curvilinear. Survey data from two studies of heterosexual adults, one conducted in England and the other in Germany, were employed. Results were parallel in each country and were not moderated by gender. Quadratic analysis indicated a curvilinear relationship, in the form of a predominantly negative, concave downward curve. Simple slope analyses suggested that when the frequency of consumption reaches once a month, sexual satisfaction begins to decrease, and that the magnitude of the decrease becomes larger with each increase in the frequency of consumption. The observational nature of the data employed precludes any causal inferences. However, if an effects perspective was adopted, these results would suggest that low rates of pornography consumption have no impact on sexual satisfaction and that adverse effects initiate only after consumption reaches a certain frequency. 相似文献

The controversial assessments of the German employment model in the literature are generally based on analyses focused on individual pillars of the model, such as the production system, or the welfare state. The present paper suggests an alternative view which takes into account the interactions between various elements of the employment model. We argue that, by the implementation of what we call a German variety of lean production, the competitiveness of the manufacturing industry has been boosted over the last few years. However, in contrast to earlier decades, the success of the export machine does not entail a more general employment dynamic. That is, the cranks between manufacturing and the rest of the employment system has been damaged substantially. Most importantly, the state has reduced its anchor role for the whole of the employment model and the potentials for its revitalisation. 相似文献

Graduating from university is just the final step of an extended educational career. Sociological transition research has revealed that final educational attainment must be understood as the result of a sequence of successive decisions. With regard to graduation from university, one has to take into account that upper secondary school qualifications are required for enrolling in the first place, and in Germany, the decision for this kind of schooling is at a much earlier age. So where on the long way to the university degree does Germany ‘lose’ its potential academics and in particular its lower class children? 相似文献

We consider appeals to social norms as a policy instrument to address consumption externalities. We explore whether appeals to social norms can be an efficient policy instrument and compare the efficiency of such appeals to the efficiency of taxation in addressing consumption externalities. We find that when the existing norm helps to shift consumption towards the socially optimal level of consumption, taxation welfare dominates appeals to social norms as a policy tool. While previous studies have found that economic instruments are superior to information in other contexts, we arrive at a different conclusion for situations where the norm shifts behavior away from what is socially optimal. In such cases appeals to social norms can be a better policy instrument than taxation. 相似文献

In this paper we will discuss constraints on the number of (non-dummy) players and on the distribution of votes such that
local monotonicity is satisfied for the Public Good Index. These results are compared to properties which are related to constraints
on the redistribution of votes (such as implied by global monotonicity). The discussion shows that monotonicity is not a straightforward
criterion of classification for power measures.

Visa policies today are a central instrument for filtering wanted and unwanted types of travellers, leading to a hierarchy of mobility rights. While there is evidence of a “global mobility divide”, we still know little about the role of regional integration when it comes to the distribution of mobility rights and the (re)structuring of mobility spaces. Against this background, the article examines the structure of visa relations in different bodies of regional integration (EU, MERCOSUR, ASEAN, ECOWAS, EAC, NAFTA, SADC and SICA). The article compares visa policies in the member states of these institutions in 1969 and 2010 from a social network perspective. While one would generally expect each institution's member states to become more similar with regard to both internal and external mobility regulations, we find that not all regional clusters align their visa policies. Potential explanations for this state of affairs are investigated. 相似文献
