The ordinal Nash social welfare function

A social welfare function entitled ‘ordinal Nash’ is proposed. It is based on risk preferences and assumes a common, worst social state (origin) for all individuals. The crucial axiom in the characterization of the function is a weak version of independence of irrelevant alternatives. This axiom considers relative risk positions with respect to the origin. Thus, the resulting social preference takes into account non-expected utility risk preference intensity by directly comparing certainty equivalent probabilities. The function provides an interpretation of the Nash-utility-product preference aggregation rule. Necessary and sufficient conditions for the function to produce complete and transitive binary relations are characterized.     

On aggregation and welfare analysis

In this article, the beginnings of a new approach to the theory of aggregation are developed. The basic idea is that aggregation should involve two things: (a) data over which social preferences are defined should be mapped into a smaller-dimensional space, and (b) there should exist an ordering on that lower-dimensional space such that an improvement in this criterion implies an improvement for any of a class of social preference functions and of a class of individual preference relations defined over the original space. Results are developed which show that this conception of aggregation can yield meaningful results; particularly with respect to comparisons of ‘real national income’ in two situations, for a given economy.     

Revealed Preference and Location Choice

The assumption that population and structural densities are defined over parcels of land with zero area is problematic when interpreting the standard residential land use model as approximating a large finite economy. This paper extends revealed preference theory to depict a spatial economy with land parcels of finite area. The model generalizes the standard utility function approach, allowing for many consumer types with different tastes and incomes and labor-leisure choice, to show that the most important predictions of the standard theory hold in the general finite framework studied here.     

On the equivalence of the Arrow impossibility theorem and the Brouwer fixed point theorem when individual preferences are weak orders

We will show that in the case where there are two individuals and three alternatives (or under the assumption of the free-triple property), and individual preferences are weak orders (which may include indifference relations), the Arrow impossibility theorem [Arrow, K.J., 1963. Social Choice and Individual Values, second ed. Yale University Press] that there exists no binary social choice rule which satisfies the conditions of transitivity, Pareto principle, independence of irrelevant alternatives, and non-existence of dictator is equivalent to the Brouwer fixed point theorem on a 2-dimensional ball (circle). Our study is an application of ideas by Chichilnisky [Chichilnisky, G., 1979. On fixed points and social choice paradoxes. Economics Letters 3, 347–351] to a discrete social choice problem, and also it is in line with the work by Baryshnikov [Baryshnikov, Y., 1993. Unifying impossibility theorems: a topological approach. Advances in Applied Mathematics 14, 404–415].

Measurement error in discrete health facility choice models: An example from urban Senegal

We use individual‐level health facility choice data from urban Senegal to estimate consumer preferences for facility characteristics related to maternal health services. We find that consumers consider a large number of quality‐related facility characteristics, as well as travel costs, when making their health facility choice. In contrast to the typical assumption in the literature, our findings indicate that individuals frequently bypass the facility nearest their home. In light of this, we show that the mismeasured data used commonly in the literature produces biased preference estimates; most notably, the literature likely overestimates consumer distaste for travel.     

Developing Stakeholder Theory

Previous literature has led to a lack of appreciation of: the range of organization/stakeholder relations that can occur; the extent to which such relations change over time; as well as how and why such changes occur. In particular, extremely negative and highly conflicting relations between organizations and stakeholders have been ignored. Due to this lack of appreciation it is argued that current attempts at integrating the separate strands of stakeholder theory to achieve a convergent stakeholder theory are premature. A model is presented which combines stakeholder theory with a realist theory of social change and differentiation. This model is intended to highlight why it is important to distinguish different stakeholders. The model also enables an analysis of the organization/stakeholder relationship, which is not exclusively from the organization perspective and which is capable of illuminating why and how organization/stakeholder relations change over time. The history of Greenpeace is used as an example.     

Collateralized Social Relations: The Social in Economic Calculation

Traditionally, economists have viewed social relations as "friction" or "impediments" to exchange and have excluded social relations from their analyses by assuming autonomous actors. Recently, however, a number of scholars—economists, sociologists, anthropologists, and other social scientists—have begun to discuss the numerous ways in which social arrangements both prompt and channel economic activity. Rational choice theory, social capital and network analysis, and agency and game theory, are among those approaches that consider the effects of social relations on economic action. In this paper we extend that discussion by arguing that social relations can function as "collateral" or assurance that an economic transaction will proceed as agreed by the parties involved. We review recent microeconomic theories and conjecture how they might be developed following this observation, which is derived from sociological and anthropological studies of economic action and organization.     

The Computational Complexity of Rationalizing Behavior

We study the computational complexity of rationalizing choice behavior. We do so by analyzing two polar cases, and a number of intermediate ones. In our most structured case, that is where choice behavior is defined in universal choice domains and satisfies the “weak axiom of revealed preference,” finding the complete preorder rationalizing choice behavior is a simple matter. In the polar case, where no restriction whatsoever is imposed, either on choice behavior or on choice domain, finding a collection of complete preorders that rationalizes behavior turns out to be intractable. We also show that the task of finding the rationalizing complete preorders is equivalent to a graph problem. This allows the search for existing algorithms in the graph theory literature, for the rationalization of choice.

Priority-driven behaviors under the Boston mechanism

We study school choice markets where the non-strategy-proof Boston mechanism is used to assign students to schools. Inspired by previous field and experimental evidence, we analyze a type of behavior called priority-driven: students have a common ranking over the schools and then give a bonus in their submitted preferences to those schools for which they have high priority. We first prove that under this behavior, there is a unique stable and efficient matching, which is the outcome of the Boston mechanism. Second, we show that the three most prominent mechanisms on school choice (Boston, deferred acceptance, and top trading cycles) coincide when students’ submitted preferences are priority-driven. Finally, we run some computational simulations to show that the assumption of priority-driven preferences can be relaxed by introducing an idiosyncratic preference component, and our qualitative results carry over to a more general model of preferences.     

Social networks and labor market transitions

We study the influence of social networks on labor market transitions. We develop the first model where social ties and job status coevolve through time. Our key assumption is that the probability of formation of a new tie is greater between two employed individuals than between an employed and an unemployed individual. We show that this assumption generally generates negative duration dependence of exit rates from unemployment. Our model has a number of novel testable implications. For instance, we show that a higher connectivity among unemployed individuals reduces duration dependence and that exit rates depend positively on the duration of the last job held by the unemployed worker.     

Intransitive social indifference and the Arrow dilemma

This paper deals with a proposal by Frederic Schick for resolving Arrow’s dilemma of social choice. Schick challenges Arrow’s assumption that rational social indifference is transitive. It turns out, however, that even if we drop this assumption, we still face a dilemma as embarrassing as Arrow’s. Any constitution which satisfies the remaining conditions is a liberum veto oligarchy. This means a unique set of individuals carries any issue on which it is unanimous, and engenders social indifference on any issue which divides it. A formal statement and proof of this theorem follows an informal presentation of the result.     

The Endogenous Economist:

A bstract . In the social sciences there exist links of communication and influence between the scientists and the actors of the modelled social systems. Social scientists are therefore endogenous parts of the systems which they study. Theories and models shouid be self-referential. The treatment of information in the rational choice models of the new classical theory, with its core assumption of rational expectations , has stopped short of extending the concept of endogeneity to the economists themselves. Economic theory proceeds on the assumption that it yields the true model and that the actors in the system share this same model even though economists have not yet agreed on this unique model. Moreover, it assumes that economists' disputes about the true model do not prompt the actors of the system to take positions and opt for one or the other of the discussed models. The use of a unique model perspective to interpret the response of financial markets to monetary announcements leads to inconclusive interpretations of the evidence. These findings are better interpreted as the result of multi model competition that has spilled over from academic science to the financial markets themselves.     

Mixture models of choice under risk

This paper is concerned with estimating preference functionals for choice under risk from the choice behaviour of individuals. We note that there is heterogeneity in behaviour between individuals and within individuals. By ‘heterogeneity between individuals’ we mean that people are different, in terms of both their preference functionals and their parameters for these functionals. By ‘heterogeneity within individuals’ we mean that the behaviour may be different even by the same individual for the same choice problem. We propose methods of taking into account all forms of heterogeneity, concentrating particularly on using a Mixture Model to capture the heterogeneity of preference functionals.

Diversification preferences in the theory of choice

Diversification represents the idea of choosing variety over uniformity. Within the theory of choice, desirability of diversification is axiomatized as preference for a convex combination of choices that are equivalently ranked. This corresponds to the notion of risk aversion when one assumes the von Neumann–Morgenstern expected utility model, but the equivalence fails to hold in other models. This paper analyzes axiomatizations of the concept of diversification and their relationship to the related notions of risk aversion and convex preferences within different choice theoretic models. Implications of these notions on portfolio choice are discussed. We cover model-independent diversification preferences, preferences within models of choice under risk, including expected utility theory and the more general rank-dependent expected utility theory, as well as models of choice under uncertainty axiomatized via Choquet expected utility theory. Remarks on interpretations of diversification preferences within models of behavioral choice are given in the conclusion.     

The Site of Diversalizing: The Accomplishment of Inclusion in Intergenerational Dance

In this study, we aim to revisit theorizing on inclusion by turning to practice theory. Challenging the individualist ontological assumption of most diversity and inclusion studies, we follow a practice-based theory of diversity to understand how an inclusive social order is accomplished. Our empirical case centres on the real-time practicing of a dance production where diversity was central to its production process as well as final performance. Using a research strategy of connected situationalism, we uncover and document three practices: mixing, inverting and affirming, that are recursively intertwined into a nexus, producing inclusion. We advance the inclusion literature by proposing the notion ‘a site of diversalizing’ that processually captures the accomplishment of multiplicity through practices and their associations in time and space, highlighting the necessity to understand ‘practice’ as the entanglement of bodily, discursive and material components, and approaching context as comprised of mutually constituting relations instead of micro/macro levels.     

Payout initiation by IPO firms: The choice between dividends and share repurchases

This study evaluates the economics of the choice of form of payout initiation mechanism adopted by IPO firms. Our results suggest that IPO firms demonstrate a preference for repurchases over dividends as the specific form of payout initiation mechanism. We however, find that while the market views post-IPO payout initiations favorably, it is indifferent to the specific form of payout mechanism adopted. Further, we find that dividends and repurchases represent distinct payout mechanisms adopted by IPO firms with fundamentally different characteristics and motivation to initiate payouts during the post-IPO phase. Our results suggest that while dividend initiations are primarily driven by life cycle and catering theory considerations, signaling theory provides the more likely explanation for payout initiations through share repurchases.     

The fundraiser's journey: A developmentally informed,grounded theory analysis

Fundraisers play a vital role in the success of nonprofit organizations, yet relatively little is known about the experiences, motivations, and thought processes that inform their career choice and development. This exploratory, cross-comparative case study of 3 fundraisers addresses this gap in the literature by examining some formative influences on fundraisers' careers, their professional growth aspirations and opportunities, and how, if at all, they engage in personal philanthropy. Results suggest that fundraisers' aptitudes, skills, and abilities may influence their career choice more than a sense of connection to the nonprofit sector or organizational mission. Further, fundraisers seek opportunities to exercise leadership at the individual, organizational, and community levels. Additionally, their personal philanthropy and social embeddedness play integral roles in their professional development. Although not large enough for generalization, these results suggest the need to study fundraisers holistically, including their psychological development and social embeddedness over time. We argue for the need to move beyond traditional marketing and public relations perspectives to explain fundraising. Instead, future studies should adopt a service-dominant logic framing that considers fundraisers as part of a larger philanthropic ecosystem. We conclude with several questions to guide future studies toward this line of inquiry.
