We estimate how cost sharing, the portion of the bill the patient pays, affects the demand for medical services. The data come from a randomized experiment. A catastrophic insurance plan reduces expenditures 31 percent relative to zero out-of-pocket price. The price elasticity is approximately -0.2. We reject the hypothesis that less favorable coverage of outpatient services increases total expenditure (for example, by deterring preventive care or inducing hospitalization).  相似文献

We exploit testing data to gain better understanding on framing effects on decision-making and performance under risk. In a randomized field experiment, we modified the framing of scoring rules for penalized multiple-choice tests. In penalized multiple-choice tests, right answers are typically framed as gains while wrong answers are framed as losses (Mixed-framing). In the Loss-framing proposed, both non-responses and wrong answers are presented in a loss domain. According to our theoretical model, we expect the change in the framing to decrease students’ non-response and to increase students’ performance. Under the Loss-framing, students’ non-response reduces by a 18%-20%. However, it fails to increase students’ scores. Indeed, our results support the possibility of impaired performance in the Loss-framing.

Ambiguity about the chances of winning represents a key aspect in lotteries. By means of a controlled field experiment, we exogenously vary the degree of ambiguity about the winning chances of lotteries organized to incentivize the contribution for a public good. In one treatment, people have been simply informed about the maximum number of potential participants (i.e. the number of lottery tickets released). In a second treatment, this information has been omitted as in all traditional lotteries. Our general finding shows that simply reducing the degree of ambiguity of the lottery leads to a sizable and significant increase (67%) in the participation rate. This result is robust to alternative prize configurations.  相似文献

This paper summarizes early findings from a social experiment that provided financial incentives for new welfare recipients to leave welfare and work full time. The financial incentive was essentially a negative income tax with a requirement that people work at least 30 h/week. Early results show that the financial incentive increased full-time employment, earnings, and income, and reduced poverty. Furthermore, at the end of the period discussed in this paper, the program was paying for itself through increased tax revenues.  相似文献

This paper examines the effect of workers' compensation on time out of work. It introduces a "natural experiment8 approach of comparing individuals injured before and after increases in the maximum weekly benefit amount. The increases examined in Kentucky and Michigan raised the benefit amount for high-earnings individuals by approximately 50 percent, while low-earnings individuals, who were unaffected by the benefit maximum, did not experience a change in their incentives. Time out of work increased for those eligible for the higher benefits and remained unchanged for those whose benefits were constant. The estimated duration elasticities are clustered around 0.3-0.4.  相似文献

In this project, we investigate downloading and sharing behaviour in a novel ‘piracy game’ modelled after standard public good games. We find that willingness to share correlates positively with the sharing by others. By contrast, actual behaviour in the ‘piracy game’ is not correlated with self-reported behaviour.  相似文献

We exploit regional variation in suitability for cultivating potatoes, together with time variation arising from their introduction to the Old World from the Americas, to estimate the impact of potatoes on Old World population and urbanization. Our results show that the introduction of the potato was responsible for a significant portion of the increase in population and urbanization observed during the eighteenth and nineteenth centuries. According to our most conservative estimates, the introduction of the potato accounts for approximately one-quarter of the growth in Old World population and urbanization between 1700 and 1900. Additional evidence from within-country comparisons of city populations and adult heights also confirms the cross-country findings.  相似文献

This paper reports on a randomized survey experiment among 1840 households, designed to compare pen-and-paper interviewing (PAPI) to computer-assisted personal interviewing (CAPI). We find that PAPI data contain a large number of errors, which can be avoided in CAPI. Error counts are not randomly distributed across the sample, but are correlated with household characteristics, potentially introducing sample bias if dubious observations need to be dropped. We demonstrate a tendency for the spread of total measured consumption to be higher on paper compared to CAPI, translating into significantly higher measured inequality. Investigating further the nature of PAPI's measurement error for consumption, we fail to reject the hypothesis that it is classical: it attenuates the coefficient on consumption when used as explanatory variable and we find no evidence of bias when consumption is used as dependent variable. Finally, CAPI and PAPI are compared in terms of interview length, costs and respondents' perceptions.  相似文献

This study deals with educational production in Austria and is focused on the impact of schoolmates on students’ academic outcomes. We use PISA 2000 and 2003 data to estimate peer effects for 15 and 16 year old students. School fixed effects are employed to address the potential self-selection of students into schools and peer groups. The estimations show significant positive effects of the peer group on students’ reading achievement, and less so for mathematics. The peer effect in reading is larger for students from less favorable social backgrounds. Furthermore, quantile regressions suggest peer effects in reading to be asymmetric in favor of low-ability students, meaning that students with lower skills benefit more from being exposed to clever peers, whereas those with higher skills do not seem to be affected much.  相似文献

We examine whether having a holiday trip affects an individual’s well-being, namely quality of life, health status, stress level and health behaviours. We use the two-stage estimation method to control for endogeneity of a travel experience, exploiting a natural experiment of distributing Travel Vouchers at random among qualified applicants in South Korea in 2012. We find that, for applicants whose decision to travel is influenced by receiving a voucher, a travel experience has no significant effects on the traveller’s well-being measured 3–12 months later. We also find that the OLS estimates overstate benefits of a travel.  相似文献

We offer an analysis of price effects of airline consolidation on a sample of transatlantic markets. While joining airlines’ networks through code-sharing decreases interline fares by up to 22.5% relative to those of non-consolidated carriers, and alliance membership also produces cost savings that decrease fares by up to 10%, antitrust immunity has no significant price effect for interline trips. Evidence that antitrust immunity increases fares on non-stop routes where it decreases competition is not robust. While total effect of airline consolidation on interline fares is about the same as indicated by previous studies, we suggest different sources of this effect. This paper is the first one presenting empirical evidence of no significant price effects of antitrust immunity.   相似文献

Personality traits are increasingly considered as a powerful predictor of socio-economic success as academic achievement. In this article, we exploit the random assignment of applicants to a programme in order to retrieve unbiased estimates of the impact of studying abroad on both cognitive and noncognitive abilities. Our findings suggest that secondary school students, especially those considered ‘more able’, benefited from a 1-month experience abroad, as it enhanced both personality traits and language proficiency.  相似文献

Abstract Debate over the effects of public versus private health care finance persists in both academic and policy circles. This paper presents the results of a revealed preference laboratory experiment that tests how characteristics of the public health system affect a subject's willingness‐to‐pay (WTP) for parallel private health insurance. Consistent with the theoretical predictions of Cuff et al. (2010), subjects’ average WTP is lower and the size of the private insurance sector smaller when the public system allocates health care based on need rather than randomly and when the probability of receiving health care from the public system is high.  相似文献

Summary. In this paper, I develop an applied general equilibrium environment with peer group effects. The application I consider is schooling. The framework used here is general equilibrium with clubs. I establish the existence of equilibrium for the economy with a finite number of school types. This result is then extended to the case where the set of school types is a continuum. The two welfare theorems are shown to hold for both economies. To compute the equilibrium, I construct a Negishi mapping from the set of weights on individual type's utility to the set of transfers that support the corresponding Pareto allocations as competitive equilibria with transfers. Because this mapping is a correspondence, a version of Scarf's algorithm is used to find a competitive equilibrium. Received: June 9, 1999; revised version: March 13, 2000  相似文献

New evidence on the transmission of monetary policy to the economy is provided through an analysis of the effects of a restrictive monetary policy shock on Italian flow of funds over the period 1980 to 2002. Firms reduce issuance of debt and decrease the acquisition of financial assets, providing no support for the existence of strong financial frictions. Following the shock, in the first quarter households increase short-tem liabilities and diminish the acquisition of liquid assets and shares. The public sector increases net borrowing during the first 2 years. Financial corporations decrease their borrowing for three quarters while in the same period the foreign sector increases borrowed funds. We claim that our results shed new light on the role of the financial decisions of the economic sectors in the transmission mechanism of monetary policy.  相似文献

The compelling effects of compulsory schooling: evidence from Canada   总被引:1,自引:0,他引:1  
Abstract.  Compulsory school laws have existed for more than a hundred years, and policies to mandate further education continue to be discussed. The implications of these laws, however, are not well understood. Historical changes to compulsory schooling in Canada permit an examination of their effects on would‐be‐dropouts under very different circumstances than those during changes in other countries. Mandating education substantially increased adult income and substantially decreased the likelihood of being below the low‐income cut‐off unemployed, and in a manual occupation. These findings suggest significant gains from this legislation, which seem unlikely offset by the costs incurred while having to remain in school. JEL classification: I20, I28  相似文献
