Summary Chronic daily cannabis use has been shown to have long term harmful health effects, which in turn is expected to reduce labour market productivity. The evidence is less clear on the health impact of less frequent consumption, which is the more typical mode of use, and previous empirical studies fail to find robust evidence of an adverse impact of these modes of use on labour market productivity. This paper attempts to shed some light on this issue by directly estimating the impact of cannabis consumption in the past week and past year on health status using information on prime age individuals living in Australia. We find that cannabis use does reduce self-assessed health status, with the effect of weekly use being of a similar magnitude as smoking cigarettes daily. Moreover, we find evidence of a dose-response relationship in the health impact of cannabis use, with annual use having roughly half the impact of weekly use.Helpful comments on an earlier draft were received from Jan van Ours, Rosalie Pacula, two anonymous referees and participants at the 81st Annual Conference of the Western Economic Association International. 相似文献

This article investigates the impact of campus bans on alcohol use and the price of alcohol on college students'drinking intensity. The impact of a campus ban on drinking appears to depend on the ability of students to substitute off-campus access to alcohol for on-campus access. Where few off-campus alternatives exist, campus bans reduce the odds that a student becomes a heavy drinker but have no impact on the odds of transitioning from abstainer to drinker. Where off-campus alternatives are more plentiful, campus bans are less effective. Increasing the price of alcohol appears to be equally effective at reducing the likelihood of drinking and heavy drinking. (JEL) 相似文献

The exchange of taxpayer-specific information between national tax authorities has recently emerged as a key and controversial
topic in international tax policy discussions, most notably with the OECD's harmful tax practices project and the EU's savings
tax initiative. This paper analyzes the effects of information exchange and withholding taxes, recognizing that countries
which agree to exchange information do not forfeit the ability to levy withholding taxes, and also focusing in particular
on the effects of innovative revenue-sharing arrangements. Amongst the findings are that: (i) the transfer of withholding
tax receipts to the residence country, as planned in the European Union, has no effect on equilibrium tax rates, but acts
purely as a lump-sum transfer; (ii) in contrast, allocating some of the revenue from information exchange to the source country—counter
to usual practice (though no less so than the EU agreement)—would have adverse strategic effects on total revenue; (iii) nevertheless,
any withholding tax regime is Pareto dominated by information exchange combined with appropriate revenue sharing; and, in
particular, (iv) sharing of the additional revenues raised from information provided, while efficiency-reducing, could be
in the interests of large countries as a means of persuading small countries to provide that information voluntarily.

This paper investigates whether cannabis use leads to worse mental health. To do so, we account for common unobserved factors affecting mental health and cannabis consumption by modeling mental health jointly with the dynamics of cannabis use. Our main finding is that using cannabis increases the likelihood of mental health problems, with current use having a larger effect than past use. The estimates suggest a dose–response relationship between the frequency of recent cannabis use and the probability of currently experiencing a mental health problem.

The spatial survival models typically impose frailties, which characterize unobserved heterogeneity, to be spatially correlated. However, the spatial effect may not only exist in the unobserved errors, but it can also be present in the baseline hazards and the dependent variables. A new spatial survival model with these three possible spatial correlation structures is explored and used to investigate the implementation of value‐added tax (VAT) in 99 countries over the period 1970–2009. Estimation is performed by a Bayesian approach through the Markov chain Monte Carlo method. The estimation results suggest the presence of a significant spatial correlation among the VAT introductions of neighbouring countries. 相似文献

This paper investigates whether maintaining a reputation for consistently beating analysts' earnings expectations can motivate executives to move from “within GAAP” earnings management to “outside of GAAP” earnings manipulation. We analyze firms subject to SEC enforcement actions and find that these firms consistently beat analysts' quarterly earnings forecasts in the three years prior to the manipulation period and continue to do so by smaller “beats” during the manipulation period. We find that manipulating firms beat expectations around 86 percent of the time in the 12 quarters prior to the manipulation period (versus 75 percent for control firms) and that manipulation often ends with a miss in expectations. We document that executives of manipulating firms face strong stock market and CEO pressure to perform. Prior to the manipulation period, these firms have high analyst optimism, growing institutional interest, and high market valuations, along with powerful CEOs. Further, we find that maintaining a reputation for beating expectations is more important than CEO overconfidence and is incremental to CEO equity incentives for explaining manipulation. Our results suggest that pressure to maintain a reputation for beating analysts' expectations can encourage aggressive accounting and, ultimately, earnings manipulation. 相似文献
