We conduct a discrete choice experiment to determine how important aid effectiveness is to people relative to other criteria for choosing countries to support with bilateral foreign aid. We find that aid effectiveness is important, on a par with recipient-country need as proxied by the level of hunger and malnutrition. Both criteria are more important than others.  相似文献

Objective: One quit attempt with varenicline has been found to be a cost-effective smoking cessation intervention. The purpose of this study was to analyze varenicline’s cost-effectiveness in patients who relapse during or after the first treatment. A comparison was made between re-treatment schema with varenicline and re-treatment schema with bupropion, NRT and unaided cessation, and treatment once with varenicline in a Finnish context.

Methods: The two-quit version of BENESCO Markov model was used to follow a cohort of smokers making up to two quit attempts over a lifetime. The abstinence rates of the interventions were derived from a Cochrane review. Gender- and age-specific data on the incidence and prevalence of five smoking-related diseases were included in the model. Quality-adjusted life-years, total expected costs, and the lifetime cumulative incidence of smoking-related morbidities and mortality were the primary outcomes evaluated.

Results: The study cohort comprised 116,533 smokers who were willing to make a quit attempt. In the lifetime simulation, re-treatment with varenicline yielded 6,150–20,250 extra quitters, depending on the comparator. Among these quitters it was possible to prevent 899–2,972 additional cases of smoking-related diseases, and 395–1,307 deaths attributable to smoking. Re-treatment with varenicline resulted in cost savings of up to 54.9 million Euros. Re-treatment with varenicline dominated all the other smoking cessation interventions used in the analysis. Sensitivity analysis supported the robustness of the base case results.

Limitations: The analysis did not consider adverse events, and included only five major smoking-related diseases, which is a conservative approach, and probably leads to under-estimation of cost-effectiveness of cessation interventions. Furthermore, assumptions of constant relative risks for smoking-related diseases for each smoking status and the proxy values used as efficacy estimates of second quit attempts for other interventions than varenicline are limitations.

Conclusions: A second quitting effort with varenicline is economically justifiable.  相似文献

Using a model of probabilistic voting, we analyze the impact of aid on the political equilibrium in the recipient country or region. We consider politicians with mixed motives: they are interested in promoting social welfare but also value the benefit of holding office. We label as clientelistic the politician who most values the benefit of being in power. We find that the impact of aid on the political equilibrium and therefore on the quality of policy in the recipient country (using utilitarian social welfare as a benchmark) ultimately depends on the value of the elasticity of the marginal utility of consumption. When elasticity is low, the expected policy outcome gets further away from the socially desirable policy set. This substitution of policy quality for aid can help to explain the poor performance of aid in improving policy. Perhaps more surprising is the opposite case, which arises for high values of elasticity of marginal utility: an increase in aid tilts the equilibrium policy towards the welfare-maximizing policy set.  相似文献

Firstly, this article simply introduces the meaning of decline industry and some points should be paid attention to when understand the meaning. Secondly, it is pointed out that the reason of aid to decline industry is the irreversibility of production factors' allocation: assets of special-purpose, labor barrier. Finally, some methods are introduced to aid decline industry.  相似文献

This paper models aid agencies as financial intermediaries that do not make a financial return to depositors, whose concern is to transfer resources to investor-beneficiaries. This leads to a problem of verifying that the agency is using donations as intended. One solution to this problem is for an agency to employ altruistic workers at below-market wages: altruistic workers, who can monitor the agency's activities, would not work at below-market rates unless they were genuinely transferring resources to beneficiaries. We consider conditions for this solution to be incentive compatible. In a model with pure moral hazard, observability of wages makes incorporation as a not-for-profit firm redundant as a commitment device. In a model with both moral hazard and adverse selection, incorporation as a not-for-profit firm can serve as a costly commitment mechanism reassuring donors against misuse of their funds. Hiring a worker of low ability can also be a valuable commitment device against fraud.  相似文献

The curse of aid     
Foreign aid provides a windfall of resources to recipient countries and may result in the same rent seeking behavior as documented in the “curse of natural resources” literature. In this paper we discuss this effect and document its magnitude. Using panel data for 108 recipient countries in the period 1960–1999, we find that foreign aid has a negative impact on institutions. In particular, if the foreign aid over GDP that a country receives over a period of 5 years reaches the 75th percentile in the sample, then a 10-point index of democracy is reduced between 0.5 and almost one point, a large effect. For comparison, we also measure the effect of oil rents on political institutions. We find that aid is a bigger curse than oil.  相似文献

This paper investigates the effect of foreign aid on governance in order to extend the debate on foreign aid and to verify common positions from Moyo’s ‘Dead Aid’, Collier’s ‘Bottom Billion’ and Eubank’s ‘Somaliland’. The empirical evidence is based on updated data from 52 African countries for the period 1996–2010. An endogeneity robust instrumental variable Two-Stage-Least Squares empirical strategy is employed. The findings reveal that development assistance deteriorates economic (regulation quality and government effectiveness) and institutional (corruption-control and rule of law) governance, but has an insignificant effect on political (political stability, voice and accountability) governance. While, these findings are broadly in accordance with Moyo and Collier on weak governance, they neither confirm the Eubank position on political governance nor the Asongu stance on the aid-corruption nexus in a debate with Okada and Samreth. The use of foreign aid as an instrument to influence the election and replacement of political leaders in Africa may have insignificant results. It is time to solve the second tragedy of foreign aid and that economists and policy makers start rethinking the models and theories on which foreign aid is used to influence economic, institutional and political governance in recipient countries.  相似文献

This study investigates how the political institutions of developed economies influence their foreign assistance. Specifically, we argue that the number of effective veto players has a negative effect on the volume of aid provision. To provide foreign assistance, the incumbent government in a donor country must have unanimous support from all effective veto players in policy making. Thus, it has more barriers to overcome when the polity is characterized by many and preference-wise heterogeneous veto players. By examining the official development assistance outflows of 27 OECD countries for the period of 1977–2006, we find empirical patterns that corroborate our argument.  相似文献

We model the aid allocation process as a rent-seeking contest between two countries and investigate the effects of differing allocation rules on recipients' behavior in a simple framework. We investigate the aid allocation mechanism design that attempts to increase the governance quality of potential recipient countries: the potential recipients spend costly resources improving governance, while the donor country allocates the fund based on their governance quality. The paper compares two mechanisms: one uses a simple winner-takes-all tournament to award the entire available purse to the country with the best governance; while under the other aid is distributed among countries in proportion to their governance qualities. The paper shows the second mechanism outperforms the first only if competing countries are sufficiently asymmetric. Moreover, the recipient who is most effective in governance – and stands to benefit the most from development assistance – has interests opposite to those of the donor. In addition, the paper shows that if the donor country allocates the fund based on both governance and the levels of poverty, it may result in a poverty trap: the leaders of potential recipient countries deliberately allocate funds away from the poorest so as not to better their position in order to receive more aid.  相似文献

An important part of the overall U.S. aid program is Public Law 480 food aid. The design of the program seeks to satisfy numerous and often conflicting objectives. Several constraints have been placed on the use by recipient countries of that aid to insure that the intentions of the program are achieved. This paper examines the implications for recipient country welfare of both the traditional and the proposed restrictions on PL480 aid. It also seeks to clarify the interpretation of empirical work on the effects of this aid. It is shown that the net value of such commodity tied aid is simply the grant component of the subsidized sale and may easily be realized by substituting food aid imports for commercial imports. Restrictions which prevent aid recipients from doing so are costly to the recipient and could lead even to immuserization. Empirical evidence obtained by others is consistent with the notion that such restrictions are circumvented, where possible, by food aid recipients. The results presented indicate that a ‘Schultzian’ disincentive effect is characteristic of a closed economy. Typical interventions on the part of recipient country governments do not effectively reclose the economy. Hence, open economy models are more appropriate frameworks for evaluating the effects of PL480 aid.  相似文献

We analyze the choice often faced by countries of whether to directly intervene to counter an external terrorist threat or to subsidize a foreign government to do it. We present a model which analyzes this policy choice where two countries, home and foreign, face a terrorist threat based in the foreign country. The home country chooses how much to invest in defending itself and in reducing terrorist resources either indirectly by subsidizing the foreign country or by directly by intervening itself and risking destabilizing the foreign country. Using a calibrated model, we are able to show that direct intervention is only an equilibrium if foreign and home efforts are not good substitutes in the technology used to reduce the resources of the terrorist group. A higher relative military efficiency by the home country makes intervention more likely.  相似文献

ABSTRACT

The development literature lacks consensus about the link between aid effectiveness and governance improvement. A basic rational actor model is introduced to clarify how donors can influence recipient behaviors and more broadly how foreign aid can support or impede governance quality improvement. Adopting the underutilized perspective of donor behavior, this study identifies mechanisms through which aid hinders governance improvement and offers substantive recommendations about how donors can enhance aid effectiveness, including strategies for donors to raise the level of effort recipients devote to project success.  相似文献
