To be or not to be involved: a questionnaire-experimental view on Harsanyi’s utilitarian ethics

According to standard theory founded on Harsanyi (J Polit Econ 61:434–435, 1953; 63:309–321, 1955) a social welfare function can be appropriately based on the individual’s approach to choice under uncertainty. We investigate how people really do rank distributions in terms of welfare. According to Harsanyi, the evaluation can be done from the standpoint of an uninvolved external judge, a public official, for example, or by a person who knows that she holds one of the positions in society, with an equal chance for any of the available positions. Are these two structures to be viewed differently? We use a questionnaire experiment to focus on the two different interpretations of the Harsanyi approach. There are important, systematic differences that transcend the cultural background of respondents.     

Played by their own play: fission and fusion in British circuses

This paper is based on fieldwork conducted in a British circus between 1975 and 1979.¹ It focuses on the dynamics of the frequent disappearance and reappearance characteristic of travelling circus shows in Britain. It shows that these dynamics are to be understood in terms of circus economics, social and semiotic constraints. It argues that, understood in these terms, the appearance and disappearance of circuses should not be taken as unequivocally confirming the notion of circus decline or, on the contrary, as supporting the notions of circus continuity (see White, 1977; Bouissac, 1976: 4; George and Mulford, 1977). Rather, they are structural characteristics of circus marginality epitomizing both circus precariousness and its endurance within the general socio-historical context.     

Facility Location with Dynamic Distance Functions

Facility location problems have always been studied with theassumption that the edge lengths in the network are static anddo not change over time. The underlying network could be used to model a city street networkfor emergency facility location/hospitals, or an electronic network for locating information centers. In any case, it is clear that due to trafficcongestion the traversal time on links changes with time. Very often, we have estimates as to how the edge lengths change over time, and our objective is to choose a set of locations (vertices) ascenters, such that at every time instant each vertex has a center close to it (clearly, the center close to a vertex may change over time). We also provide approximation algorithms as well as hardness results forthe K-center problem under this model. This is the first comprehensive study regarding approximation algorithmsfor facility location for good time-invariant solutions.     

The Advantage of Activity-based Modelling for Air-quality Purposes: Theory vs Practice and Future Needs

Activity-based modelling treats travel demand as derived from the demand for activities. This approach has important advantages for emissions and air-quality analyses. An ideal activity-based model will describe the chain of activities in which each person in the household is involved during the day. The information on an activity includes the location, start and end times, mode of travel and travel time. Such a model, together with a traffic micro-simulation application, can provide perhaps the best information needed for an analysis and evaluation of emissions and air-quality benefits of transportation control measures. The article describes the advantages of activity-based modelling for emissions and air-quality analysis and evaluates the feasibility of practical applications to provide this type of benefits. The first application of an activity-based model in the USA is examined. Its advantages for emissions and air-quality analyses are evaluated against the traditional four-step model and with ideal activity based models.     

Regulation on Migrant Workers’ Employment in the Israeli Construction Sector

This article deals with a reform in the regulation on employment of migrant workers which was implemented in the Israeli construction industry from 2005. This corporations‐based arrangement replaced a restrictive employment arrangement which tied the employee to a specific employer. The new regulation of work conditions and wages, coupled with a significant reduction in the number of work permits issued to construction, has improved work conditions and wages paid to migrant workers, and made their employment less attractive to employers. The reform also included elements designed to reduce the illegal employment phenomenon and to encourage migrant workers to leave the country at the end of their contracts. However, the new arrangement still restricted the mobility of migrant workers to some extent and had negative consequences such as a significant rise in the broker fees demanded of workers.     

Structural sources of personnel problems in multinational corporations: Third-country nationals

The paper examines the extent to which multinational corporations (MNCs) whose staffing policies approach the genuine multinational model are free of the dysfunctions found by the authors in earlier studies of ethnocentric MNCs. The findings are based on comparative research in 51 MNCs, and intensive diagnostic studies of seven subsidiaries of MNCs operating and headquartered in four continents. The findings may be summed up as follows: (1) certain, but very few, morale problems have indeed been eliminated; (2) others are still present; (3) others are still present and their effect has intensified; and (4) new problems have appeared which are unique to the staffing policy approximating to the genuine multinational model. These findings shed new light on several of the assumptions underlying this model. The general conclusion is that each prevalent type of staffing policy has several sources of morale problems—some inherent in its uniqueness, and others shared by the alternative staffing policies—irrespective of the personal qualifications of the managers. Therefore, it is unrealistic to expect that a change toward the genuine multinational model would solve the basic morale problems prevalent in the dominant type of MNCs.     

Ellsberg Revisited: An Experimental Study

An extension to Ellsberg's experiment demonstrates that attitudes to ambiguity and compound objective lotteries are tightly associated. The sample is decomposed into three main groups: subjective expected utility subjects, who reduce compound objective lotteries and are ambiguity neutral, and two groups that exhibit different forms of association between preferences over compound lotteries and ambiguity, corresponding to alternative theoretical models that account for ambiguity averse or seeking behavior.
