We find that the staggered passage of state-level laws that legalize marijuana for medical use increases states' borrowing costs by 7–9 basis points. Consistent with economic theory on substance use suggesting that marijuana legalization increases local consumption of the drug (by expanding its availability and reducing its perceived risks), we predict and find that increased consumption represents an important mechanism that explains the higher state bond spreads. We also show that following such laws’ passage, states incur higher marijuana-consumption-related expenditures, including for police, corrections, and public welfare. 相似文献

We analyse the effect of unemployment on health using information from the German Socio-Economic Panel of the years 1991-2008. To establish a causal effect we rely on fixed-effects methods and plant closures as exogenous entries into unemployment. Although unemployment is negatively correlated with health, we do not find a negative effect of unemployment due to plant closure on health across several health measures (health satisfaction, mental health, and hospital visits). For this subgroup of the unemployed, unemployment does not seem to be harmful and selection effects of ill individuals into unemployment are likely to contribute to the observed overall correlation between poor health and unemployment. 相似文献

This paper considers the impact of Programa de Educación, Salud y Alimentación ( PROGRESA ), a large Mexican rural anti-poverty programme that had an evaluation sample in which overall treatment was randomly assigned to some communities but not others, on child nutrition. When we examine the impact of PROGRESA based on the presumption of randomized allocations, we find that PROGRESA had no or even a negative impact on child nutrition. However, not all children designated to receive nutritional supplements actually did so. Our preferred estimates – child fixed-effects estimates that control for unobserved heterogeneity that is correlated with access to the supplement – indicate a significantly positive and fairly substantial programme effect of the nutritional supplements on children 12–36 months. They imply an increase of about a sixth in mean growth per year for these children and a lower probability of stunting. Effects are somewhat larger for children from poorer communities but whose mothers are functionally literate. The long-term consequences of these improvements are non-trivial; its impact working through adult height alone could result in a 2.9% increase in lifetime earnings. 相似文献

A lab experiment was conducted in France to evaluate the impact of health information on consumers’ choices for functional food. Successive messages revealing benefits and uncertainties of consuming yoghurts with added plant sterols for reducing cholesterol were delivered. Results show a significant and positive influence of the message linked to the cholesterol reduction on willingness to pay, even for participants without cholesterol. However participants expressed little interest in information about potential risks and scientific uncertainties, since their impacts on willingness to pay are not always statistically significant. An econometric estimation shows a significant link between the change in willingness to pay and the perception by participants regarding the scientific validity linked to the sterols. 相似文献

The article uses the case study of coffee, tea and cocoa to analyse whether tariff escalation constitutes a barrier to market access that thwarts diversification efforts of developing countries into exports of value‐added agricultural processed products. It also examines the extent to which non‐tariff barriers act as market access barriers that constrain developing countries from developing their exports of agricultural processed products. Our analysis shows that tariff escalation is not the main barrier; rather it is the prevalence of non‐tariff barriers (including domestic non‐tariff barriers) that limits the ability of developing countries to increase their agricultural processed exports. This has important policy implications in terms of the emphasis that trade negotiators and policy planners should place on addressing non‐tariff barriers. 相似文献

This paper uses a data set collected among inhabitants of Amsterdam, to study whether wages of prime‐age male workers are affected by cannabis use. The analysis shows that recent cannabis use has a negative effect on wages. The size of the wage effect depends on the age of onset. The earlier the start of cannabis use the larger the negative wage impact. 相似文献

Unequal distribution of fiscal resources and lower prioritization of budget towards healthcare are the most important challenges in achieving universal health coverage in India. This study has examined relationships between government health expenditure and fiscal space (i.e. tax revenue, non-tax revenue, fiscal transfer, and borrowings) in twenty-one states of India for the period of 1980–2014. Our panel regression results imply that mobilization of tax revenue has a positive impact, while borrowings have a negative impact on the allocation of government expenditure on healthcare in the long-run. The panel quantile regression results show that states associated with the low and middle level of revenue growth have been mobilizing finance through central government transfer and borrowings in short-run. Further, the panel vector error correction models show that sum of the lagged coefficients of borrowings have a greater impact on health financing process as compared to other sources of fiscal space at short-run, and the speed of adjustment towards long-run equilibrium is relatively slower. The overall analysis concludes that less domestic revenue mobilization and higher dependency of borrowings for healthcare financing may create fiscal stress on state finances in the long-run, and thereby it could possibly reduce the prioritization of spending. Therefore, improvement in revenue growth and proper utilization of fiscal transfer would be appropriate policy implications from this study. 相似文献

Using university administrative and survey data drawn from the AlmaLaurea Consortium, we analyze the effect of time to degree on the early labor market performance of Italian graduates. The empirical strategy allows identifying separately the impact of elapsed time to degree on the transition from university to work and on earnings from other determinants specific to the academic path completed. Findings suggest that delayed graduation reduces the employment probability (0.8% points for each year of delay), and this effect is still persistent five years after graduation. Once employed, graduates not completing their degree within the minimum period are also penalized in their net monthly earnings, even five years after graduation. The most penalized groups are women and graduates in non-scientific fields. 相似文献
