Did Vietnam veterans get sicker in the 1990s? The complicated effects of military service on self-reported health

The veterans disability compensation (VDC) program, which provides a monthly stipend to disabled veterans, is the third largest American disability insurance program. Since the late 1990s, VDC growth has been driven primarily by an increase in claims from Vietnam veterans, raising concerns about costs as well as health. We use the draft lottery to study the long-term effects of Vietnam-era military service on health and work in the 2000 Census. We find no evidence that military service affected overall employment rates or overall work-limiting disability rates (that is, health conditions that make work difficult). At the same time, military service sharply increased federal transfer income, especially for lower skilled white men, among whom there was also a large negative impact on employment and a marked increase in disability rates. The differential impact of Vietnam-era service on low-skilled men cannot be explained by more combat or war-theatre exposure for the least educated, because high school graduates were at least as likely to be exposed to combat or war theatre as the less-educated. This leaves the relative attractiveness of VDC for less-skilled men and the work disincentives embedded in the VDC system as a likely explanation for our findings.     

The dynamics of responder behavior in ultimatum games: a meta-study

Using data aggregated from seven papers that study repeated play in standard ultimatum games with either stranger or absolute stranger matching, we show that the behavior of responders changes with experience. High offers are more likely to be accepted with experience and low offers are more likely to be rejected. At the individual level, there is a negative relationship between the likelihood that a given offer is accepted and the size of the preceding offer. We compare the results with predictions generated by static models of distributional preferences, implicitly dynamic models of preferences with reciprocity, and explicitly dynamic models of adaptive learning. The data is most consistent with models of preferences with reciprocity.     

Pricing multi-class network services using the Shapley Value

This paper investigates pricing issues in class-based networks. Classes of packets having lower impatience and longer average delay receive monetary compensations. The inter-class price differential is determined by the inter-class compensations. The paper also presents rules for allocating network resource to each class. The corresponding payoff (disutility share) for each class is driven by the Shapley Value of the associated cooperative game.     

Capitalism,Meritocracy, and Social Stratification: A Radical Reformulation of the Davis‐Moore Thesis

This article advances a reconceptualization of the Davis‐Moore thesis, which adresses the weaknesses of Davis and Moore's original formulation and can function not as a causal explanation of inequality but as a normative yardstick, against which the efficiency of capitalist society's use of human talents can be measured. I argue that the nonmeritocratic nature of capitalist society prevents it from using human talents efficiently and that this fact is obscured by a “meritocratic illusion” that is systematically generated by the structural logic of capitalist society. After briefly exploring one way in which capitalism's ecological contradictions impinge on the Davis‐Moore thesis, I conclude by arguing that it is the mediation of capitalism's contradictions through social struggles that will determine whether a more meritocratic society consistent with the reconceptualized version of the Davis‐Moore thesis will ever emerge.     

The Quality of Insurance Intermediary Services—Empirical Evidence for Germany

Competing insurance intermediaries provide heterogeneous services that are difficult for incompletely informed consumers to assess. Transaction cost economics, search theory, and principal‐agent theory provide arguments on product quality differences between exclusive agents and independent intermediaries. This article uses a sample of 927 insurance intermediaries in Germany. By performing OLS estimations, we test the impact of the different distribution channels and other factors on intermediaries’ service quality. Depending on the proxies used for service quality, we find mixed evidence for the product quality hypothesis. Service quality depends to a large extent on the information‐gathering and processing activities of the individual intermediaries, independent of the respective distribution channel.     

How long might the younger-old live: A predictive model

Life expectancy amongst older people in industrialised countries has been improving over an extended period and still continues to do so. This has ramifications for providers of services to this population, thus necessitating a level of forward planning. Predictive models of remaining life expectancy for older age groups can assist long-term planning processes. This paper presents an extrapolative approach to forecasting remaining life expectancy. Based on logistic modelling of historic mortality and survivorship for the “younger-old” male population of England and Wales over the period 1970-2005, a parsimonious two-parameter model is derived. This model provides a close correspondence to published period life table data. Trends in these parameters are then fitted and extrapolated to enable projections of life expectancy up to 40 years into the future. Alternative assumptions are used to determine a range of future life expectancy trajectories for a 65-year-old male. Occupational pension scheme provision is identified as an area of particular concern in the context of increasing longevity. As an illustration, the life expectancy trajectories are combined with differing discount rate assumptions to generate a number of alternative pension liability scenarios for the extrapolation period.     

Toward a Humanist Reconstruction of Economic Science

This paper examines whether governance matters for the economic growth of developing countries, empirically captured within the institutional economics theoretical framework using the panel data estimation procedure. In doing so, it tests the effect of several dimensions of governance on the growth of 84 low and middle-income economies using regression specifications common in the growth literature. The empirical results show that political stability and government effectiveness is significantly positively correlated with growth. Voice and accountability and corruption are statistically significantly negatively correlated with growth. The regulatory quality and rule of law dimensions of governance are negatively but statistically insignificantly correlated with growth. The findings of this study imply that the dynamics of the current modern economy makes it necessary for developing countries to act now and within their own country, improve the dimensions of governance and establish good governance practices that are domestically relevant and internationally comparable and consistent.     

ARE ALL ECONOMIC FACTS GREATLY EXAGGERATED? THEORY COMPETITION AND SELECTIVITY

Abstract ..There is growing concern and mounting evidence of selectivity in empirical economics. Most empirical economic literatures have a truncated distribution of results. The aim of this paper is to explore the link between publication selectivity and theory contests. This link is confirmed through the analysis of 87 distinct empirical economics literatures, involving more than three and a half thousand separate empirical studies, using objective measures of both selectivity and contests. Our meta–meta‐analysis shows that publication selection is widespread, but not universal. It distorts scientific inference with potentially adverse effects on policy making, but competition and debate between rival theories reduces this selectivity and thereby improves economic inference.
