In this article, we develop a model of the demand for cigarettes that incorporates forward-looking behavior related to the adverse health consequences of smoking and the addictive nature of cigarettes. The model results in several testable hypotheses that we use to examine the extent to which smokers exhibit forward-looking behavior. Results of our study are generally supportive of the notion that smokers behave in a forward-looking manner.  相似文献

In order to achieve an ‘optimal health system’, health policies should not only be focused on the supply of health care, but also take cognisance of the demand for health care. Studies of health care demand in South Africa are scarce due to considerable data limitations. This analysis attempts to fill this gap by combining two data sets (specifically, the GHS 2004 and IES/LFS 2000) in order to be able to utilize the wealth of information regarding health care utilization in the General Household Survey. The aim is to inform and encourage debate on how to incorporate demand side considerations in order to arrive at improved public health care in South Africa.  相似文献

This article uses a large data set of sibling births to examine when mothers must quit smoking in pregnancy to deliver healthy babies. It applies sibling fixed effects models to provide robust evidence that smoking cessation in the first trimester has a negligible effect on infant health, but cessation as late as second trimester or smoking throughout pregnancy is associated with substantially lower birth weights and higher risks of delivering low birth weight babies. In particular, about two thirds of the total detrimental smoking impact on birth outcomes occurs in the second trimester. Therefore, reallocating resources on prenatal smoking cessation towards the first trimester can lead to a significant efficiency gain. This study also shows when the timing information of prenatal smoking cessation is improperly used, it will introduce a new nontrivial downward bias in estimating the causality between the conventionally used group measure “prenatal smoker” and infant health.  相似文献

One of the greatest achievements of the twenty‐first century has been the dramatic decline in malaria prevalence notably in endemic developing countries. In this study, we estimate the impact of recent scale up in malaria control in Senegal on neonatal, postnatal and infant mortality. We exploit natural preintervention variation in malaria prevalence to estimate the impact of recent malaria control policy in Senegal. In a difference in differences design, we find a negative and significant effect on neonatal and infant mortality in malaria endemic regions while the impact on postnatal mortality is inconclusive. We rule out competing explanations such as contemporaneous health campaigns, general improvement in health care delivery and pre‐existing regional time trends. We identify a 26.9% and 16.3% reduction in neonatal and infant mortality, respectively, in malaria endemic regions during 2005–2014. We argue that increase in donor funding for malaria control as well as greater involvement of local communities and civil society organization has proven to be effective. However, the impact of malaria control on mortality may vary substantially depending on early or late infant mortality.  相似文献

The encouragement of care of orphans and vulnerable children by non-profit organisations (NPOs) is a major policy response to the HIV and AIDS epidemic in South Africa. The purpose of this article is to present a quality–cost model with five performance indicators for quality and two for costs and to test these against actual performance using data collected from nine rural and urban organisations in 2004 and 2005. Six NPOs had acceptable cost but all had unacceptable quality scores; three had unacceptable cost and unacceptable quality scores. Each rural caregiver had many more orphans and vulnerable children beneficiaries than their urban counterparts but made fewer total visits. As a result, urban beneficiaries received, on average, 3.5 times more visits than their rural counterparts. The results suggest the need for different performance indicators and expectations for rural and urban NPOs and that monitoring and evaluation using the model could improve horne community-based care services.  相似文献

The federal/state Medicaid program is designed to provide health insurance for the nation's poorest, yet between 15 and 20 percent of the population continue to have no health insurance. Classic utility-based insurance theory is examined to see if it well explains why some do and some do not purchase health insurance at the state level or if a host of other non-economic factors are needed. This pooled, cross-sectional time-series analysis shows that the state characteristics most strongly associated with the prevalence of a lack of health insurance is the percent of persons whose income falls below the poverty line, the percent of the state's population that is female and the percent of the population with only a high school education. This analysis suggests that the starting point for policies aimed at limiting the number of insured should be limiting poverty and perhaps recognizing the gender/education influence in designing state eligibility requirements.  相似文献

The study seeks to re‐investigate the role of price, income and health awareness in the evolution of South African cigarette demand over the period 1996 to 2006. At first glance, rising cigarette prices appear to have played an important role in reducing cigarette consumption over the sample period, especially during the late 90s. But how dependent is the impact of price increases on general economic conditions and overall health awareness among smokers? Health awareness, in particular, has not received sufficient attention in the South African context, due to a lack of data. Previous estimates of price and income elasticities of cigarette demand are based on long annual time series data, which do not allow for changes in underlying tastes and preferences. The paper attempts to disentangle the forces of price, income, health awareness and policy intervention using a quarterly data set. In addition, the study also cautions against the upward bias in estimates derived from formal cigarette sales data – in the light of increasing illicit cigarette volumes in South Africa.  相似文献

The goal of the Affordable Care Act (ACA) was to achieve nearly universal health insurance coverage through a combination of mandates, subsidies, marketplaces, and Medicaid expansions, most of which took effect in 2014. We use data from the Behavioral Risk Factor Surveillance System to examine the impacts of the ACA on health care access, risky health behaviors, and self-assessed health after two years. We estimate difference-in-difference-in-differences models that exploit variation in treatment intensity from state participation in the Medicaid expansion and pre-ACA uninsured rates. Results suggest that the ACA led to sizeable improvements in access to health care in both Medicaid expansion and nonexpansion states, with the gains being larger in expansion states along some dimensions. However, we do not find clear effects on risky behaviors or self-assessed health.  相似文献

This article contributes to the literature examining how stress during the early stages of life impacts later-life health using a novel proxy for stress: risk of military induction during the Vietnam War. The article estimates that an increase in induction risk in young adulthood is associated with higher rates of obesity, endocrine disease, and hypertension later in life. These findings do not appear to be cohort effects; these associations exist only for men who did not serve in the war, not for same-aged women. These results suggest stress experienced during early adulthood can have adverse health consequences later in life.  相似文献

We estimate the effects of U.S. Metropolitan Statistical Area housing prices on a variety of health outcomes and health-related behaviors separately for homeowners and tenants. The constructed data set consists of information on individuals from the 2002–2012 Behavioral Risk Factor Surveillance System combined with homeownership data from the March Current Population Survey and housing prices from Freddie Mac. We estimate positive effects on homeowners' mental health when housing prices increase. We also find negative effects on tenants' health and health-related behaviors with increases in housing prices. These estimated contemporaneous effects are concentrated among low-income homeowners and tenants, and the effects for tenants are not persistent in the long run. However, the cumulative effects of an increase in housing prices on obesity become more pronounced for homeowners in the long run, resulting in worse self-reported health.  相似文献

This paper evaluates the drastic reforms of Japanese public health insurance initiated in 2006. We employ a computable general equilibrium framework to numerically examine the reforms for an aging Japan in the dynamic context of overlapping generations. Our simulation produced the following results: first, an increase in the co-payment rate, a prominent feature of the 2006 reform, would promote economic growth and welfare by encouraging private saving. Second, the ex-post moral hazard behavior following the increase in co-payment rates, however, reduces economic growth. Third, Japan's trend of increasing the future public health insurance benefits can mainly be explained by its aging population, and increasing the co-payment rate does little to reduce future payments of public health insurance benefits. Fourth, the effect on future economic burdens of reducing medical costs through efficiencies in public health insurance, emphasis on preventive medical care, or technological progress in the medical field is small. Finally, a policy of maintaining public health insurance at a fixed percentage of GDP will require reducing public health insurance benefits, perhaps up to 45% by 2050. Such a policy also reduces economic growth until approximately 2035. Our simulation indicates that the reform does not significantly reduce future public health insurance benefits, but it can enhance economic growth and welfare by encouraging private saving.  相似文献

This article estimates the impact of the introduction of Medicaid managed care (MMC) on the formal Medicaid participation of children. We employ a quasi‐experimental approach exploiting the location‐specific timing of MMC implementation in Kentucky. Using data from the March Current Population Survey from 1995 to 2003, our findings suggest that the introduction of MMC increases the likelihood of being uninsured and decreases formal Medicaid participation. This finding is consistent with an increase in “conditional coverage,” waiting until medical care is needed to sign up or re‐enroll in Medicaid. These effects are concentrated among low‐income children and absent for high‐income children. We find no evidence of “crowd‐in,” substituting private coverage for Medicaid. These results are robust to multiple placebo tests and imply the potential for less formal participation (i.e., more conditional coverage) among the Affordable Care Act‐Medicaid expansion population (which is likely to be primarily covered under MMC) than is typically predicted.  相似文献

Among the factors thought to contribute to lagging improvements in infant health in recent years are increasing obesity and diabetes prevalence among women of childbearing age. This article uses a difference‐in‐difference‐in‐difference empirical strategy to investigate the impact of mandated insurance coverage for diabetes on adverse pregnancy outcomes. Among educated women, who have high rates of coverage through private insurance that is subject to insurance mandates, diabetes mandates are associated with a reduction in low birth weight and premature birth prevalence. These gains are concentrated among older women and are larger for African‐Americans. There is a weaker effect on the prevalence of high birth weight, potentially because of the deleterious effects of an increased probability of pregnancy weight gain in excess of 35 pounds among diabetic women in states with mandates.  相似文献

A growing body of literature suggests that office‐motivated politicians manipulate fiscal policy instruments to enhance their reelection prospects. This article directly examines the impact of fiscal policy on incumbents’ reelection prospects by focusing on the impact of public investment. This impact is estimated using a panel of 20 countries belonging in Organisation for Economic Co‐operation and Development over the period 1972–1999. We find that the level of public investment in the earlier years of an incumbent's term in office improves their reelection prospects, whereas election year manipulation of public investment is neither rewarded nor punished. Our evidence also suggests that, after controlling for the level of deficit and public investment, the level of government revenue both in the election and nonelection years does not seem to affect reelection prospects. Moreover, we find that deficit creation during elections and in nonelection years are not rewarded by voters.  相似文献

Certificate‐of‐Need (CON) programs for new hospital construction are intended to foster the best selection among competing hospital applications, given demands for hospital care in the community. Yet, the merits of CON depend in part on the quality of the comparative review process. This article examines a case study in Florida to illustrate the utility of empirical evaluations using patient choice models. I estimate such models to show how patients would respond to a change in hospital choices. By simulating the welfare effects of the proposed hospitals, I can further predict how prices of hospital care differ by applicant. Results suggest that empirical analysis using data on patient choice of hospitals may better inform the review process. At the same time, however, it may not give a unique ranking without additional analysis of the fixed costs of proposed services in the context of existing marketwide capacity.  相似文献

This article demonstrates the critical relationship between the characteristics of the production function and the strategic incentives in a team. Equilibrium effort increases in team size when substitutability is low relative to returns to scale. Effort levels are actually strategic complements when returns to scale exceed the substitutability of members' effort. Moreover, even with equal shares the well‐known problem is determined by returns to scale and becomes worse as returns increase. While a target scheme can support the optimal output level as an equilibrium, it does not completely deter free riding. A team member will accommodate shirking by increasing their own effort within a remarkably large “accommodation zone” where the additional effort cost is less than the bonus. This accommodation of shirking by others exists for different returns to scale and even for very low levels of substitutability.  相似文献

As part of the Patient Protection and Affordable Care Act, participating hospitals have part of their Medicare reimbursements withheld and then redistributed based on quality performance. The Hospital Value‐Based Purchasing reimbursement plan relies partly on ordinal rankings of hospitals to determine how money is distributed. We analyze the quality metric score distributions that underlie payment redistribution and show that there is not enough information to reliably differentiate hospitals from one another near the program point cutoffs, and conclude that a large part of the payment formula is driven by sampling variability rather than true quality information. An alternative plan for rewarding hospitals is developed.  相似文献

This article investigates the relationship between the timing of Supplemental Nutrition Assistance Program (SNAP) benefit payments and participation in school lunch and breakfast using the National Household Food Acquisition and Purchase Survey. An event study approach examines participation over the five‐day window before and after the SNAP payment. We find that school lunch participation decreases by 17–23 percentage points immediately after the SNAP payment among 11–18 year olds while breakfast drops by 19–36 percentage points. The decline begins the day prior to payment. We find no effects for 5–10 year olds. Models examining participation over the full SNAP month using individual fixed effects yield similar findings. Among teenagers, participation in school lunch and breakfast decline in the first two weeks of the SNAP month, increasing afterward. Non‐school meals show the opposite pattern. Overall, results indicate SNAP households rely more on school lunch and breakfast toward the end of the SNAP month.  相似文献
