THE IMPACT OF BODY WEIGHT ON OCCUPATIONAL MOBILITY AND CAREER DEVELOPMENT

This article examines the relationship between individuals' weight and employment decisions over the life cycle. I estimate a dynamic stochastic model of individuals' annual choices of occupation, hours worked, and schooling. Evidence suggests that heavier individuals face higher switching costs when transitioning into white‐collar occupations, earn lower returns to experience in white‐collar occupations, and earn lower wages in socially intensive jobs. I simulate a hypothetical antidiscrimination policy treating obese workers as a protected class. Although such a policy would reduce gaps in occupational attainment, it would have little effect on the observed divergence in wages between obese and nonobese workers.     

Equilibrium Effects of Superstition in the Housing Market

We investigate the interaction of product quality differentiation and consumer preference heterogeneity in durable goods markets, focusing on the effects of secondary market liquidity and consumer heterogeneity on equilibrium prices. We build an infinite‐horizon dynamic model of the apartments housing market that captures the above features. Some apartments are considered lucky, and some consumers are superstitious. Lucky apartments are valued more highly than non‐lucky ones only by superstitious consumers. Results show that the difference between the lucky apartment price and the non‐lucky apartment price becomes smaller when the secondary market becomes less liquid and when consumers’ preference heterogeneity becomes more persistent as opposed to time‐varying.     

A quantile regression approach for estimating panel data models using instrumental variables

We introduce a quantile regression approach to panel data models with endogenous variables and individual effects correlated with the independent variables. We find newly developed quantile regression methods can be easily adapted to estimate this class of models efficiently.     

DISCRETE CHOICE AND RATIONAL INATTENTION: A GENERAL EQUIVALENCE RESULT

This article establishes a general equivalence between discrete choice and rational inattention models. Matějka and McKay (2015) showed that when information costs are modeled using the Shannon entropy, the choice probabilities in the rational inattention (RI) model take the multinomial logit form. We show that, for one given prior over states, RI choice probabilities may take the form of any additive random utility discrete choice model (ARUM) when the information cost is a Bregman information, a class defined in this article. The prior information of the rationally inattentive agent is summarized in a constant vector of utilities in the corresponding ARUM.     

A Poisson mixture model of discrete choice

In this paper, we introduce a new Poisson mixture model for count panel data where the underlying Poisson process intensity is determined endogenously by consumer latent utility maximization over a set of choice alternatives. This formulation accommodates the choice and count in a single random utility framework with desirable theoretical properties. Individual heterogeneity is introduced through a random coefficient scheme with a flexible semiparametric distribution. We deal with the analytical intractability of the resulting mixture by recasting the model as an embedding of infinite sequences of scaled moments of the mixing distribution, and newly derive their cumulant representations along with bounds on their rate of numerical convergence. We further develop an efficient recursive algorithm for fast evaluation of the model likelihood within a Bayesian Gibbs sampling scheme. We apply our model to a recent household panel of supermarket visit counts. We estimate the nonparametric density of three key variables of interest-price, driving distance, and their interaction-while controlling for a range of consumer demographic characteristics. We use this econometric framework to assess the opportunity cost of time and analyze the interaction between store choice, trip frequency, search intensity, and household and store characteristics. We also conduct a counterfactual welfare experiment and compute the compensating variation for a 10%-30% increase in Walmart prices.     

Network externalities and long-run market shares

We study a dynamic duopoly model with network externalities. The value of the product depends on the current and past network size. We compare the market outcome to a planner. With equal quality products, the market outcome may result in too little standardization (i.e. too many products active in the long run) but never too much. The potential inefficiency is non-monotonic in the strength of the network effect, being most likely for intermediate levels. When products differ in quality, an inferior product may dominate even when the planner would choose otherwise, but only if the discount factor is sufficiently large     

当代生产管理领域之学术成果回顾——由精敏到延迟战略

自从工业革命以来，生产典范历经一连串的移转过程，由大量生产逐步发展出大量客制化、精实生产、敏捷及最新的精敏等概念。这些概念中，又以20世纪末才出现的敏捷与精敏较少为人所知。本研究试图将敏捷与精敏的学术成果作较完整的回顾，以找出关于这两个概念的问题中，什么论点已经被回答，以及还有什么论点有待进一步的探索。此外，由于许多学者都指出，企业如果要达到敏捷与精敏，须通过延迟战略才能实现。因此本研究也试图回顾有关评估延迟战略之效益的研究，以对未来的研究发展提供方向。     

Corporate sustainability strategies in institutional adversity: Antecedent,outcome, and contingency effects

This study examines (i) how top-level managerial institutional ties drive corporate sustainability strategies of emerging market firms operating under conditions of institutional adversity; (ii) the impact of corporate sustainability strategies on market performance; and (iii) the moderating role of financial resource slack on the relationships between corporate sustainability strategies and market performance. The study builds from institutional development logic and the structure–conduct–performance paradigm. Primary data are collected from 300 firms operating in a major sub-Saharan African market. Findings show that top-level managerial institutional linkages with regulatory national governmental officials, local community leaders, and top managers at other firms drive corporate proactive and responsive sustainability strategies, which in turn influence market performance. In addition, the findings reveal that financial resource slack strengthens the path between corporate proactive sustainability strategies and market performance, but not the path between corporate responsive sustainability strategies and market performance. Theoretical and practical implications are discussed.     

Going Underground: Banal Nationalism and Subterranean Elements in Argentina’s Falklands/Malvinas Claim

ABSTRACT

This article calls for consideration of underground elements that have been typically overlooked or unseen in debates about the nation and banal nationalism. The materialities and (re)presentation of elements such as earth, sand and rock have the capacity to be affective, contentious, to embody intimate memories of conflict and to reinforce national territorial aspirations. These subterranean elements have been ‘nationalised’, bathymetrically mapped and deployed by Argentina to make claims over territories in the South Atlantic, including the Falklands/Malvinas. Rather than re-examining these technical procedures undertaken by the state and analysing what they mean for the geopolitics of the South Atlantic, this article explores how the subterranean is manifest in everyday reproductions of nationalism and national memory in Argentina. It presents insights from research undertaken in a range of different environments in Argentina, encompassing museums, veterans’ centres and public monuments, to demonstrate how the presence of the elemental in the everyday can reinforce and also disrupt banal (territorial) nationalism. Furthermore it argues for conceptualisation of the elemental as part of a relational network that links matter, national citizenries and territories together. The conclusion posits that the subterranean elements and their (re)presentation are essential to understanding the materialisation of banal nationalism as part of the everyday reproduction and rejection of claims to ‘national’ territory.
