The Relationship Between Education and Adult Mortality in the United States   总被引:7,自引:0,他引:7  
Prior research has uncovered a large and positive correlation between education and health. This paper examines whether education has a causal impact on health. I follow synthetic cohorts using successive U.S. censuses to estimate the impact of educational attainment on mortality rates. I use compulsory education laws from 1915 to 1939 as instruments for education. The results suggest that education has a causal impact on mortality, and that this effect is perhaps larger than has been previously estimated in the literature.  相似文献

We develop regime-switching factor models in which the number of factors determines the operative economic regime. To illustrate the proposed methodology, we analyze the covariance structure of a widely studied set of 25 equity portfolios.  相似文献

This paper deals with a special case of estimation with grouped data, where the dependent variable is only available for groups, whereas the endogenous regressor(s) is available at the individual level. By estimating the first stage using the available individual data, and then estimating the second stage at the aggregate level, it might be possible to gain efficiency relative to the OLS and 2SLS estimators that use only grouped data. We term this the mixed-2SLS estimator (M2SLS). The M2SLS estimator is consistent and asymptotically normal. We also provide a test of efficiency of M2SLS relative to OLS and “2SLS” estimators.  相似文献

The aim of this work is to demonstrate how public university hospital (UH) managers can improve the process of decision-making by using the measurement of economic value added to the society (EVAS) generated by these organizations. Thus, the economic values of the organization and its departments were calculated, according to the theory studied: measurement model of economic result of Slomski (1996). It was considered the conduction of a case study in a public UH, evaluating its economic performance in a 3-year period. For the interpretation of results, the Data Envelopment Analysis (DEA) which categorized the departments of the hospital studied as efficient or inefficient was used. This study revealed that managers can improve the decision-making process by using the EVAS, since it has been established that this measurement of economic value has sensitivity to identify which of the economic value drivers should be emphasized in the management.  相似文献

This paper endogenizes the number of firms in an industry with positive network effects, complete incompatibility, and firms that compete in quantity. To this end, we compare two possibilities: free entry and second‐best number of firms (the one that maximizes social welfare). We show that with business‐stealing competition, free entry yields, in general, more firms than the socially optimal solution. In addition, we find that by the nature of the industry with firm‐specific networks, total production may be greater or lower under free entry than with a regulator; moreover, some industries attain their maximum social welfare with a monopoly.  相似文献

Based on a comparison of Berlin and Tel Aviv, this article investigates the ways in which ensembles of participatory instruments mediate between neoliberal urban regimes and political agency shaping differentially the meaning of participation and the types of claims that can be advanced. The article gives an overview of the recent history of both cities through the lens of participatory politics. Two in‐depth case studies further examine the relationship between participatory politics and claim making in each setting: the recent conflict over a social center in the district of Friedrichshain‐Kreuzberg in Berlin and the Levinsky tent city of 2011 in Tel Aviv. In the concluding section, the article suggests that, rather than assuming that participatory tools either co‐opt movements or can be appropriated by them, we need to rethink the relationship between participatory tools, rights and recognition, and ask how participatory structures and political agency constitute each other in interwoven dynamics.  相似文献

A lack of empirical studies on Supply Chain Risk Management (SCRM) is observed, especially in the industries of large projects. Therefore, this paper conducts a risk analysis on the Brazilian Shipbuilding Industry by generating an initial risk profile. A panel was conducted with executives from major shipyards, and the primary risks were identified, assessed, and evaluated. Findings corroborate the academic literature, reinforcing that companies recognise the importance of SCRM, but the concept is incipient and far from being successfully implemented in real life. Despite the fact that the shipyards identified important risks, the focus was on internal factors. Because the industry was exposed to risks from the external environment, no risk mitigation actions existed, resulting in the bankruptcy of many shipbuilders. This research is an initial step toward investigating SCRM techniques, offering academics a novel empirical approach that can serve as a systematic risk management tool for supply chain planning.  相似文献

We investigate whether corruption distorts the positive effect of public health expenditure and taxation on growth through panel data analysis of 75 developing countries for the period from 1995 to 2014. The findings indicate that, although both public health expenditure and taxation can increase economic growth, in countries with more corrupt governments this effect is reduced.  相似文献

By specializing Montero’s (J Environ Econ Manag 44:23–44, 2002) model of environmental regulation under Cournot competition to an oligopoly with linear demand and quadratic abatement costs, we extend his comparison of firms incentives to invest in R&D under emission and performance standards by solving for a closed form solution of the underlying two-stage game. This allows for a full comparison of the two instruments in terms of their resulting propensity for R&D and equilibrium industry output. In addition, we incorporate an equilibrium welfare analysis. Finally, we investigate a three-stage game wherein a welfare-maximizing regulator sets a socially optimal emission cap under each policy instrument. For the latter game, while closed-form solutions for the subgame-perfect equilibrium are not possible, we establish numerically that the resulting welfare is always larger under a performance standard.  相似文献

In this paper, we show that the 1986 Mitra–Wan result establishing asymptotic convergence of maximal programs to the unique golden-rule forest in the case of undiscounted, strictly concave felicity functions can be strengthened, in the same setting, to the  uniform  asymptotic convergence of  optimal  programs to the unique golden-rule forest. We work with a notationally reformulated version of the model that may have independent interest.  相似文献
