We show that, if giving is equivalent to not taking, impure altruism could account for List’s (in Journal of Political Economy 115(3):482–493, 2007) finding that the payoff to recipients in a dictator game decreases when the dictator has the option to take. We examine behavior in dictator games with different taking options but equivalent final payoff possibilities. We find that recipients tend to earn more as the amount the dictator must take to achieve a given final payoff increases, a result consistent with the hypothesis that the cold prickle of taking is stronger than the warm glow of giving. We conclude that not taking is not equivalent to giving and agree with List (in Journal of Political Economy 115(3):482–493, 2007) that the current social preference models fail to rationalize the observed data.  相似文献

本文扼要阐述了经济全球化发展的前景和潜力,并运用李嘉图模型对全球化可能导致的经济损害作出论证分析进而说明,尽管经济学家在极大程度上趋向于将全球化视为基本良性的现象,但全球化仍然对某些国家(包括发达国家)带来经济损害,及对部分人群可能造成极其痛苦的后果。不过,源自于全球化的不断增长的竞争压力,会加强创新和增长,从长远来看,的确对每个国家有利。  相似文献

We examine the relationship between the administrative enforcement of environmental regulation, ethnic heterogeneity, and other community characteristics in New Jersey and New York. We find that the percentage of non-white population in a community is positively related with administrative penalties imposed on violators. However, penalties are lower in more ethnically diverse communities. This result may be due to the fact that these communities are less likely to coordinate to create solidarity across ethnic groups and demand stronger enforcement.  相似文献

This paper examines the relationship between casino gambling and bankruptcy rates in U.S. counties using a panel of U.S. county-level data from 1990 through 2005. We contribute to the literature in several ways, perhaps most notably by examining the possibility that the effect of a casino on bankruptcy may differ over the casino’s lifespan. Results confirm this possibility, indicating that the impact of casinos on bankruptcy follows a “U-shaped” curve over the life of the casino. More specifically, regression analysis indicates the existence of a casino in a county increases the bankruptcy rate by more than 9% in the first year of operation. The percentage of additional bankruptcies then decreases through the third year after the casino opens. Bankruptcy rates in casino counties then slightly fall below that of non-casino counties during the fourth through seventh years after opening, increasing once again in the eighth year and thereafter. This cycle corresponds closely to the 6 year statute of limitations period applicable to Chapter 7 bankruptcies.  相似文献

Abstract

Background: The prevalence of nontuberculous mycobacterial lung disease (NTMLD) in the US has increased; however, data characterizing the associated healthcare utilization and expenditure at the national level are limited.

Objective: To examine associations between economic outcomes and the use of anti-Mycobacterium avium complex (MAC) guidelines-based treatment (GBT) for newly-diagnosed NTMLD in a US national managed care claims database (Optum® Clinformatics® Data Mart).

Methods: NTMLD was defined as having ≥2 claims for NTMLD (ICD-9 031.0; ICD-10 A31.0) on separate occasions ≥30?days apart (between 2007 and 2016). The cohort included patients insured continuously over a period of at least 36?months (12?months before initial NTMLD diagnostic claim and for the subsequent 24?months). Treatment was classified as GBT (consistent with American Thoracic Society/Infectious Diseases Society of America guidelines), non-GBT, or untreated. All-cause hospitalization rates and total healthcare expenditures at Year 2 were assessed as outcomes of the treatment prescribed in Year 1 after NTMLD diagnosis.

Results: A total of 1,039 patients met study criteria for NTMLD (GBT, n?=?294; non-GBT, n?=?298; untreated, n?=?447). After adjustment for baseline characteristics, GBT was associated with a significantly lower all-cause hospitalization risk vs non-GBT (odds ratio [OR]?=?0.53; 95% CI = 0.33–0.85, p?=?0.008), and vs being untreated (OR = 0.57; 95% CI = 0.35–0.91, p?=?0.020). Adjusted total healthcare expenditure in Year 2 with GBT ($69,691) was lower than that with non-GBT ($77,624) with a difference of ?$7,933 (95% CI = ?$14,968 to ?$899; p?=?0.03).

Conclusions: Patients with NTMLD in a US managed care claims database who were prescribed GBT had lower hospitalization risk than those who were prescribed non-GBT or were untreated. GBT was associated with lower total healthcare expenditure compared with non-GBT.  相似文献

Much research is needed to determine the extent to which the high school social studies curriculum, and certain courses within that curriculum, contribute toward economic understanding. Boddy and Tocco report on their attempt to assess the social studies curriculum in Southwest Florida. They also single out one required course, Americanism vs. Communism, which was designed to “emphasize the free-enterprise-competitive economy of the United States,” and measure its impact on a sample of high school seniors. The findings are not encouraging. Although this study applies to one limited geographic area, others may find it interesting because it suggests the need for similar research in other parts of the nation.  相似文献

We examine the potential for IFRS to influence the market for SEOs in the UK and France. The divergence between the UK domestic accounting standards and IFRS is minor (low-divergence firms) whereas domestic accounting standards in France differ materially from IFRS (high-divergence firms); however, both countries have similar legal enforcement and institutional settings that might confound the effect of IFRS adoption. We argue that IFRS adoption serves to mitigate information asymmetry and improve accounting quality. Accordingly, we find that, following IFRS adoption, earnings management activities decrease among high-divergence firms prior to issuing SEOs. As a result of the lower levels of earnings management and information asymmetry, we predict and find that the market reaction to issuing SEOs improves significantly for high-divergence firms following IFRS. Given that equity financing becomes less costly, we find that the propensity to issue new SEOs increases among high-divergence firms after IFRS adoption. We find no similar changes among low-divergence firms. The results persist after running a matched-sample analysis and controlling for potential self-selection bias.  相似文献
