Foreign aid, the real exchange rate (RER), and economic growthare three key variables that shape the aftermath of civil warsin many developing countries. Panel estimations drawn from asample of 39 conflict and 44 nonconflict countries between 1970and 2004 indicate that although postconflict countries receivelarger aid flows and exhibit moderate RER overvaluation afterpeace is attained, overvaluation cannot be traced to aid. Yetforeign aid is among the significant determinants of the equilibriumRER. Aid is also an important determinant of economic growth,particularly after peace is reached. Aid exhibits decreasingreturns, however, and interacts negatively with RER overvaluation.RER overvaluation reduces growth, but this effect is amelioratedby financial development. Postconflict policies should thereforeaim to use aid prudently, avoid RER misalignment, and supportfinancial and capital market development to achieve high andstable growth in the aftermath of war and beyond. 相似文献

We exploit a unique setting of accounting regulation change to examine how accounting information quality affects the well-documented accrual anomaly. We show a significant reduction in the negative return predictability of accruals among UK companies with poorer accounting information quality following the introduction of Financial Reporting Standard No. 3: Reporting Financial Performance (FRS3). While the functional fixation hypothesis attributes the mispricing of accruals to the judgemental error of end-users of information, our findings suggest that the supply side of information also plays a crucial role. Our results provide evidence that regulatory interventions seeking to improve accounting information quality can reduce the mispricing of securities in the capital market. 相似文献

We generalize May’s theorem to an infinite setting, preserving the elementary character of the original theorem. We define voting scenarios and generalized voting scenarios, and prove appropriate versions of May’s theorem. The case of generalized voting scenarios specialized to a countably infinite set of voters and the collections of all coalitions that have asymptotic density, shows that majority rule is the only aggregation rule that satisfies neutrality, irrelevance of null coalitions, anonymity, and positive responsiveness. 相似文献

Many economists have long held that market failures create a gap between social and private returns to research and development (R&D), thereby limiting private incentives to invest in R&D. However, this common belief that firms significantly underinvest in R&D is increasingly being challenged, leading the rationale behind public support for private R&D to be questioned. In this paper, we attempt to clarify the perspectives of two sources: the theoretical literature on endogenous growth, and its recent developments in integrating a geographical dimension, and the empirical literature that measures the social returns to R&D in relation to the private returns. Ultimately, we are able to clearly distinguish among different types of market failures and compare their relative impact on the gap between the private and social returns to R&D. Two main conclusions are reached. First, systematic firm underinvestment in R&D is not demonstrated. Second, even though instances of underinvestment do occur, they are mainly explained by surplus appropriability problems rather than by knowledge externalities. This suggests the need for a new policy mix that employs more demand‐oriented instruments and is more concentrated on identifying efficient allocations among activities rather than merely increasing global private R&D investment. 相似文献

Our aim in this paper is to evaluate the causal effect of foreign acquisition on research and development (R&D) intensity in targeted domestic firms. We are able to distinguish domestic multinational enterprises (MNEs) and non‐MNEs, which allows us to investigate the fear that the change in ownership of domestic MNEs to foreign MNEs leads to a reduction in R&D activity in the country. Overall, our results give no support to the fears that foreign acquisition of domestic firms leads to a relocation of R&D activity in Swedish MNEs. Rather, in this paper, we find robust evidence that foreign acquisitions lead to increasing R&D intensity in acquired domestic MNEs and non‐MNEs. 相似文献

Abstract To provide a normative foundation for transfers between different economies, one needs information on their ‘per capita welfare.’ This paper considers various methods for doing this and reaches the following conclusions: (i) Such global welfare comparisons are more demanding than usually thought. (ii) The ranking of methods differs from that of local (over‐time) comparisons, with real comprehensive per capita NNP being the least impractical method. The lesson is that global welfare comparisons should be performed with great care. The comparisons must be made in local real prices calculated according to ‘purchasing‐power‐parity,’ where non‐traded environmental amenities play an important role. 相似文献

This paper proposes a new test of Tiebout sorting that relies on the exogenous time structure of recurrent local elections. The test is based on the idea that competitive elections represent periodic perturbations to the Tiebout equilibrium of local public good provision and allocation of households to communities, so that their schedule should affect the timing of households' sorting decisions. On the other hand, internal migration flows that have nothing to do with the demand for public goods over which localities vote recurrently ought to be orthogonal to the timing of elections in a reduced-form migration equation. I exploit the staggered schedule of mayoral elections in Italy to analyze migration, elections, and public budget data across several thousands of municipalities, and find evidence of a systematic influence of the electoral calendar on the timing of sorting decisions. 相似文献

We investigate a common‐value labor setting in which firms interview a worker prior to hiring. When firms have private information about the worker's value and interview decisions are kept private, many firms may enter the market, interview, and hire with positive probability. When firms' interview decisions are revealed, severe adverse selection arises. As a result, all firms except for the highest‐ranked firm are excluded from the hiring process. 相似文献

This paper looks at interactions between foreign aid and the public sector in developing countries, especially those considered to be fragile or failing states. A model is proposed which employs actual budgetary appropriations and revenue estimates (rather than estimated target variables) and allows for asymmetric preferences. Variants of the model are estimated using time-series data for Papua New Guinea (PNG). PNG is classified as a fragile state by the international community owing to perceived policy and institutional inadequacies. Results obtained suggest that foreign aid increases consumption and investment expenditures and decreases tax revenues and the level of borrowing. 相似文献

To secure their membership in a popular group, individuals may contribute more to the group's local public good than they would if group formation were exogenous. Those in the most unpopular group do not have this incentive to contribute. This may result in substantial differences in individual effort level between groups. Our model thus provides one explanation for the existence of group‐specific behavioral norms. A principal will prefer exogenous or endogenous group formation depending on whether he prefers high or low levels of the local public good. We analyze two stylized examples: social interaction in schools, and multiple‐task teamwork. 相似文献
