Antibody tests: They are more important than we thought

Antibody testing is a non-pharmaceutical intervention – not recognized so far in the literature – to prevent COVID-19 contagion. I show this in a simple economic model of an epidemic in which agents choose social activity under health state uncertainty. In the model, susceptible and asymptomatic agents are more socially active when they think they might be immune. And this increased activity escalates infections, deaths, and welfare losses. Antibody testing, however, prevents this escalation by revealing that those agents are not immune. Through this mechanism, I find that antibody testing prevents about 12% of COVID-19 related deaths within 12 months.     

Testing the intertemporal labor supply model: are jobs important?

The neoclassical life-cycle labor supply model assumes that hours of work are determined by labor supply choices alone and does not include a role for employers or job distinctions. An alternative model in which employers have an interest in employee hours and changing jobs is costly may reconcile weak and conflicting evidence regarding the neoclassical model. An important implication of such an alternative is that individuals may face hours constraints on a job and thus can choose hours freely only between jobs. This paper tests several implications of the neoclassical model against this alternative model of hours determination. Using a unique panel of individuals and jobs constructed using data on women from the 1988–1992 Panel Study of Income Dynamics, I compare hours variances and labor supply elasticities measured within and between jobs. Results provide some evidence against the neoclassical model and suggest that ignoring the role of employers in determining hours of work can lead to downward bias in estimates of labor supply elasticities.     

Models of stochastic choice and decision theories: why both are important for analyzing decisions

We select a menu of seven popular decision theories and embed each theory in five models of stochastic choice, including tremble, Fechner and random utility model. We find that the estimated parameters of decision theories differ significantly when theories are combined with different models. Depending on the selected model of stochastic choice we obtain different rankings of decision theories with regard to their goodness of fit to the data. The fit of all analyzed decision theories improves significantly when they are embedded in a Fechner model of heteroscedastic truncated errors or a random utility model.

Observability and Sorting in a Market for Names

Can firm names be tradeable assets when changes in name ownership are observable? Earlier literature focuses on trading of firm names when trading is not observable to the consumer. Yet, casual empiricism suggests that shifts in name ownership are often publicly known. This paper studies how firm names can be traded even under full observability. In equilibrium, even when consumers see a reputed name being divested they continue to trust it and so, these names are tradeable. I further demonstrate an appealing “sorting” property of these equilibria. Competent firms can separate themselves by buying valuable names, and incompetent firms can give themselves away by using worthless names.

Equally important criteria and demanding aggregation

Within the class of weighted averages of ordered measurements on criteria of ‘equal importance’, we discuss aggregators that help assess to what extent ‘most’ criteria are satisfied, or a ‘good performance across the board’ is attained. All aggregators discussed are compromises between the simple mean and the very demanding minimum score. The weights of the aggregators are described in terms of the convex polytopes as induced by the characteristics of the aggregators, such as concavity. We take the barycentres of the polytopes as representative weights.     

Toponymy as Commodity: Exploring the Economic Dimensions of Urban Place Names

In recent years the study of urban toponymy (place names) has been revitalized by the emergence of a ‘critical toponymies' approach. This focuses on the cultural politics of place naming and the decisions involved in attributing names to the urban landscape. However, in contemporary cities place names have an economic role in addition to their political role. In particular, there have been recent calls for more attention to the commodification of place‐naming rights and practices. This article seeks to respond to these calls by addressing the issue of urban place names as commodities. It begins by examining the naming of sports stadia by corporate sponsors. It then considers a range of ways in which private‐sector interests are increasingly influencing the naming of the urban landscape, from buildings and neighbourhoods to individual streets. Even the material signage that identifies street names can be appropriated within branding and promotional strategies. Moreover, urban place names are increasingly incorporated into a range of commercially produced spatial datasets collated by private companies. The article ends by proposing a number of directions for future research into the economic role of urban place names and the commodification of toponymy more broadly.     

Metonymy in Language about Organizations: A Corpus-Based Study of Company Names

abstract    In this paper, I examine the use of metonymies in people's talk about organizations. Drawing upon a corpus of natural talk extracted from the British National Corpus (BNC) I identify recurring categories of metonymies that appear to be a central part of people's talk about organizations. These categories of metonymies involve substitutions where an organization stands in for its members, its products, its facilities, its stock or shares or a company-related event. I also found that metonymies in each of these categories are used as basic metonymic expressions that are only partially connected to metaphorical expressions and interpretations of organizations. Where those connections exist, the use of metonymies follows a metaphor-from-metonymy linguistic pattern (where a metaphorical meaning arises from the use of a metonymy) rather than a metonymy-within-metaphor pattern (where a metonymy is part of a metaphorical expression). I elaborate on the implications of these findings for our understanding of how organizations are discursively constructed and understood through metonymic language.
