Do people have accurate beliefs about the behavioral consequences of incidental emotions? Evidence from trust games

The present study examined people’s expectations of how incidental emotions could shape others’ reciprocity in trusting situations, whether these expectations affect people’s own behavior, and how accurate these expectations are. Study 1 explored people’s beliefs about the effects of different incidental emotions on another person’s trustworthiness in general. In Studies 2 and 3, senders in trust games faced angry, guilty, grateful, or emotionally neutral responders. Participants who were told about their counterpart’s emotional state acted consistently with their beliefs about how these emotions would affect the other’s trustworthiness. These beliefs were not always correct, however. There were significant deviations between the expected behavior of angry responders and such responders’ actual behavior. These findings raise the possibility that one player’s knowledge of the other’s emotional state may lead to action choices that yield poor outcomes for both players.     

中国都市密集区市际关系中存在的问题及其应对

当前，中国都市密集区市际关系中存在的问题包括产业结构趋同、恶性竞争、城市定位重复混乱、地方保护主义以及基础设施重复建设等。都市密集区市际关系中存在的复杂问题，与市际关系协调机制不成熟、不完善密切相关。创新都市密集区市际关系协调的制度和机制，实现协调主体的多元化、方式多样化、目标长期化，是当前都市密集区发展中殊为迫切的任务。     

The limitations of using school league tables to inform school choice

Summary. In England, so-called 'league tables' based on examination results and test scores are published annually, ostensibly to inform parental choice of secondary schools. A crucial limitation of these tables is that the most recent published information is based on the current performance of a cohort of pupils who entered secondary schools several years earlier, whereas for choosing a school it is the future performance of the current cohort that is of interest. We show that there is substantial uncertainty in predicting such future performance and that incorporating this uncertainty leads to a situation where only a handful of schools' future performances can be separated from both the overall mean and from one another with an acceptable degree of precision. This suggests that school league tables, including value-added tables, have very little to offer as guides to school choice.     

4万亿经济激励计划背后的经济学问题

凯恩斯的宏观经济理论既不涉及现实的政治维度，也不关注微观经济层面的资源配置效率问题，这样的理论应用于现实的结果很可能是弊大于利。作为应用凯恩斯理论的总需求管理思想的产物，中国4万亿的经济刺激计划在政治层面难以避免寻租和腐败、政治权力固化等问题，在经济层面有可能导致资源配置的扭曲。虽然政府出台了各种监管措施以预防这种可能出现的弊病，但经验和理论都告诉我们这些措施的有效性是有限的。     

Assessing the Concept of the ‘Insecure‐Other’ Category in the Cassidy–Marvin Scheme: Changes Between 4 and 6 Years in the English and Romanian Adoptee Study

We set out to explore the meaning of the attachment categories in the Cassidy/Marvin strange situation procedure, as employed in the home, using data from a longitudinal study of children adopted into UK families up to the age of 42 months from Romanian institutions, and of adopted children without the experience of institutional care––both groups being assessed at 4 and 6 years of age. Inter‐rater reliability was found to be good. Security (meaning the use of the parent as a secure base and no negative behavior on reunion) was the modal categorical rating in both the institution‐reared and comparison groups, but the category of anomalous non‐normative behavior (meaning a lack of any ordered attachment behavior as covered by the standard ratings), previously labeled ‘insecure‐other’, was more common in the institution‐reared children. Because this was unassociated with the usual manifestations of insecurity (such as avoidance or resistance) and because it was largely evident in interactions with the stranger, it is concluded that the adjective ‘insecure’ was not appropriate. Although this ‘insecure‐other’ category was associated with disinhibited attachment as reported by parents (meaning a lack of differentiation among adults, a willingness to go off with strangers and a lack of checking back with parents in anxiety‐provoking situations), it did not prove to be a good index of disinhibited attachment because changes over time in the ‘insecure‐other’ category were not associated with changes in the rate of disinhibited attachment. Also, whereas the rate of ‘insecure‐other’ fell markedly in the institution‐reared group between 4 and 6 years of age, it rose in the comparison group, raising queries over its meaning.

Leveraging the common and outsourcing the distinct: institutional difference and multinational company identity in emerging economies

ABSTRACT

This paper explores the challenges of outsidership faced by multinational companies (MNCs) accessing emerging economies. The paper departs from popular conceptualisations of culture drawing instead on social identity theory as part of an institutions-based view, to explain how employing a singularities approach can allow the identification of commonalities of Indianness and Australianness that can be leveraged to ameliorate negative socially embedded business norms that pose a challenge to MNC success in emerging economies. This study shows that despite recognised formal (regulatory) and informal (cultural) differences, managers of Australian MNCs operating in India were able to innovatively identify and exploit cultural commonalties/singularities to ease cultural adjustment and mitigate intergroup conflict, allowing them to achieve an innovative institutional fit. The paper discusses how, using this approach, sole-venture MNCs can access many of the benefits provided by collaborative entry modes while preserving MNC identity. We further propose that the singularities approach can provide a valuable starting point to develop culturally appropriate competence training initiatives.     

Bounding Optimal Expected Revenues for Assortment Optimization under Mixtures of Multinomial Logits

We consider assortment problems under a mixture of multinomial logit models. There is a fixed revenue associated with each product. There are multiple customer types. Customers of different types choose according to different multinomial logit models whose parameters depend on the type of the customer. The goal is to find a set of products to offer so as to maximize the expected revenue obtained over all customer types. This assortment problem under the multinomial logit model with multiple customer types is NP‐complete. Although there are heuristics to find good assortments, it is difficult to verify the optimality gap of the heuristics. In this study, motivated by the difficulty of finding optimal solutions and verifying the optimality gap of heuristics, we develop an approach to construct an upper bound on the optimal expected revenue. Our approach can quickly provide upper bounds and these upper bounds can be quite tight. In our computational experiments, over a large set of randomly generated problem instances, the upper bounds provided by our approach deviate from the optimal expected revenues by 0.15% on average and by less than one percent in the worst case. By using our upper bounds, we are able to verify the optimality gaps of a greedy heuristic accurately, even when optimal solutions are not available.
