The Price of Alcohol,Wife Abuse,and Husband Abuse

Alcohol consumption has been frequently linked to violence. This paper examines the direct relationship between the price of alcohol, which determines consumption, and violence toward husbands and wives. The data come from the 1985 cross section and the 1985-1987 panel of the National Family Violence Survey. A reduced form violence equation is estimated, and individual-level fixed effects are used to control for unobserved characteristics in the panel. Results indicate that an increase in the price of pure alcohol, as measured by a weighted average of the price of alcohol from beer, wine, and liquor, will reduce violence aimed at wives. The evidence on the propensity of an increase in the price of alcohol to lower violence toward husbands is mixed.     

Arthur McIvor and Ronald Johnston. Miners' Lung: A History of Dust Disease in British Coal Mining

Over the course of the past two decades, historians have begunto pay serious and sustained attention to the history of occupationalhealth, much of it analyzing the role of social, economic, andpolitical factors in the medical recognition of industrial disease.Although much has been published about the British coal industry,this is the first book to address the issue of health and safetyin this critically important sector of the British economy.Miners’ Lung, building on the work done by Jo     

Does the Length of Maternity Leave Affect Maternal Health?

The objective of this paper is to investigate the impact of the length of maternity leave on maternal health in a sample of working mothers. Two measures of depression and a measure of outpatient health visits are used to represent maternal health. Ordinary least squares models provide baseline estimates, and instrumental variables models account for the potential endogeneity of the return-to-work decision. The findings suggest that returning to work later is associated with a reduction in the number or frequency of depressive symptoms. There is suggestive but inconclusive evidence that longer maternity leave is associated with a lower probability of being a likely case of clinical depression and a lower likelihood of having frequent outpatient visits during the first six months after childbirth. These findings contribute to the literature on maternal leave policy, which focuses primarily on the benefits of leave for child health and development, by evaluating the influence of longer maternal leave on the health of mothers.     

A NOTE ON SEMIVARIANCE

In a recent paper ( Jin, Yan, and Zhou 2005 ), it is proved that efficient strategies of the continuous-time mean–semivariance portfolio selection model are in general never achieved save for a trivial case. In this note, we show that the mean–semivariance efficient strategies in a single period are always attained irrespective of the market condition or the security return distribution. Further, for the below-target semivariance model the attainability is established under the arbitrage-free condition. Finally, we extend the results to problems with general downside risk measures.     

In honor of Michael Grossman

This symposium is to celebrate the accomplishments of Michael Grossman on the occasion of his retirement from teaching. The articles selected are all written by Mike's former students and colleagues, and were presented in a session at the 2017 Annual Meeting of the Southern Economic Association. Each of the articles celebrate Mike's scholarly legacy in developing the field of health economics.     

Child Access Prevention Laws and Nonfatal Gun Injuries

Many states have passed child access prevention (CAP) laws, which hold the gun owner responsible if a child gains access to a gun that is not securely stored. Previous research on CAP laws has focused exclusively on gun‐related deaths even though most gun injuries are not fatal. We use annual hospital discharge data to investigate whether CAP laws are associated with decreased nonfatal gun injuries. Results from Poisson regressions that control for various hospital, county, and state characteristics, including state‐specific fixed effects and time trends, indicate that CAP laws are associated with reductions in nonfatal gun injuries among children under age 18. Our results are bolstered by the absence of effects on other outcomes such as self‐inflicted gun injuries among adults and nongun self‐inflicted injuries.     

如何在创新早期鉴别产品创意——MAU理论和分层Bayesian模型的一个整合运用

<正>导言产品创意是衔接产品创新平台与产品概念确立的桥梁,是企业创新过程中的重要一环。一个企业通常在产品的创新策略、市场定位以及核心竞争力的基础上发展其创新平台。创新平台,就其本质而言,是宽泛且战略的。具有诸如"良性"、"生动性"或"便利性"的抽象特征。一旦企业定义了自身的创新平台,就能够发掘出未满足的消
