The effects of mass shootings on gun sales: Motivations,mechanisms, policies and regulations

Surges in firearm sales after mass shootings have been well documented in the United States. This study presents three main findings regarding the impact of mass shootings on firearm demand and the moderating roles played by political and regulatory climates. First, mass shootings led to an immediate but temporary increase in gun sales. This effect continued for approximately 3–6 months after the incidents and was larger for shootings with a greater number of fatalities. Second, the association between mass shootings and gun sales was significant only under Democratic presidents. The party affiliation of the state legislature and state-level gun control did not moderate this association. Third, the increased firearm sales after mass shootings did not result in a higher level of firearm ownership. It appeared most purchases were made by current gun owners stockpiling additional firearms, thus indicating the fear of stricter gun control as a likely motivation. This study offers the following policy implications: (a) the public debates concerning gun violence could have the unintended consequence of raising gun demand among current owners, (b) the message of tightening gun control could increase the total stock of firearms in circulation, and (c) the regulations to prevent future mass shootings may be better addressed by the state government as a state-level regulation does not trigger demand response among potential consumers.     

Non-Gaussian Ornstein–Uhlenbeck-based models and some of their uses in financial economics

Non-Gaussian processes of Ornstein–Uhlenbeck (OU) type offer the possibility of capturing important distributional deviations from Gaussianity and for flexible modelling of dependence structures. This paper develops this potential, drawing on and extending powerful results from probability theory for applications in statistical analysis. Their power is illustrated by a sustained application of OU processes within the context of finance and econometrics. We construct continuous time stochastic volatility models for financial assets where the volatility processes are superpositions of positive OU processes, and we study these models in relation to financial data and theory.

Health Risk and Portfolio Choice

This article investigates the role of self-perceived risky health in explaining continued reductions in financial risk taking after retirement. If future adverse health shocks threaten to increase the marginal utility of consumption, either by absorbing wealth or by changing the utility function, then health risk should prompt individuals to lower their exposure to financial risk. I examine individual-level data from the Study of Assets and Health Dynamics Among the Oldest Old (AHEAD), which reveal that risky health prompts safer investment. Elderly singles respond the most to health risk, consistent with a negative cross partial deriving from health shocks that impede home production. Spouses and planned bequests provide some degree of hedging. Risky health may explain 20%% of the age-related decline in financial risk taking after retirement.     

Incremental Sampling Methodology: Applications for Background Screening Assessments

This article presents the findings from a numerical simulation study that was conducted to evaluate the performance of alternative statistical analysis methods for background screening assessments when data sets are generated with incremental sampling methods (ISMs). A wide range of background and site conditions are represented in order to test different ISM sampling designs. Both hypothesis tests and upper tolerance limit (UTL) screening methods were implemented following U.S. Environmental Protection Agency (USEPA) guidance for specifying error rates. The simulations show that hypothesis testing using two‐sample t ‐tests can meet standard performance criteria under a wide range of conditions, even with relatively small sample sizes. Key factors that affect the performance include unequal population variances and small absolute differences in population means. UTL methods are generally not recommended due to conceptual limitations in the technique when applied to ISM data sets from single decision units and due to insufficient power given standard statistical sample sizes from ISM.

钱锺书诗《乡人某属题〈哭儿记〉……》的本事

文章考索了钱锺书《乡人某属题〈哭儿记）,儿从军没缅甸,其家未得耗,叩诸乩,神降书盘曰：“归去来兮,胡不归？”》一诗的本事：1942年6月,时任叙昆铁路副工程师的胡敬侃（即诗题中的“儿”）死于随征战印缅战场的中国远征军撤回国内的途中,当时连尸骨都无法收殓。其父胡粹士得闻噩耗后,作《哭儿记》征请亲友题咏,钱锺书因有此作。而诗中“四万义军同日尽,世间儿子漫纷纷”,则是将胡敬侃之死事,放到一个更阔大的背景上,抒写了更为深广的沉痛之情。
