In cases where policy makers accept ``bribes'' offered by organised lobbies or interestedparties, government decisions can be modelled as a first price menu auction. In this paper we adaptthis structure to model debt repudiation. We considera one-period model in which two generations, parents and children, are present, and debt titles are unevenlydistributed among parents. The government can repaythe debt by a combination of taxes on the children'sincome and on the outstanding debt. We excludeintergenerational conflicts, assuming that the parents'and children's objective is to maximise the utility ofthe family. In this perspective, families make offersthat relate monetary contributions to the taxstructures chosen by the government. On the hypothesisthat all interests are represented, we obtain theresult that the government is indifferent to the taxstructure. 相似文献

Down payment or closing cost assistance is an effective program in addressing the wealth constraints of low‐and moderate‐income homebuyers. However, the spillover effect of such programs on the neighborhood is unknown. This paper estimates the impact of the City of Dallas Mortgage Assistance Program (MAP) on nearby home values using a hedonic model of home sales from 1990 to 2006. We define neighborhoods of 1,000 feet around each sale and estimate the average differences in sales prices between neighborhoods with various numbers of MAP properties before and after their appearance. We find that MAP properties tend to locate in neighborhoods with lower property values; however, unless a concentration of MAP properties forms, the infusion of MAP properties has little detrimental impact on neighboring property values. Moreover, low concentration of MAP properties has a modest positive impact on surrounding property values. © 2010 by the Association for Public Policy Analysis and Management. 相似文献

Financial year 2005 marks the gradual introduction of the international accounting standard (IAS) as part of a broad project promoted by the EU to achieve consistency and comparability and, consequently, greater transparency in corporate accounts, with benefits for the users and institutions who make use of, or exercise control over them. The present paper will not address all the related complex profiles (e.g., actuarial methodologies, financial evaluation models, cash-flows scenarios generation techniques). Actual aim is to bring evidence for the gradual shifting of perspective promoted by the financial community as far as the insurance companies are concerned: Once considered as unknown "black-boxes" because of their peculiarities, western countries' most authoritative agencies and largest private investors felt for a long time uneasy to manage insurance companies' disclosures. More recently, since the industry has been absorbed in the world-wide trend toward global conglomerate encompassing banking, finance and insurance, western regulators have undertaken a sound effort to move insurance disclosures from a technical to a financial view, boosting a dramatic homologation to other financial institutions (Cesarini & Varaldo, 1992; Forestieri & Moro, 1993; Locatelli, et al., 1999). The trade-off, the authors intend to show, is now between more transparent outlook and an insider's knowledge of an industry whose peculiarities are inescapable. 相似文献

Native species of trees and shrubs contribute significantly to farmers' livelihoods by supplying food, medicinal products, fodder, and wood. In the case study reported in this article, this contribution to farmers' annual revenue varied from 26 per cent to 73 per cent, and was as high as US$ 650 a year for households for which agroforestry products were the primary source of revenue. Household consumption was not quantified in the study, but farmers' comments confirmed that native trees also played an important role in assuring food security, especially in the ‘hunger period’ when grain stores are low and farmers are waiting for the next harvest. 相似文献

现代科学技术的迅猛发展对司法审判产生了巨大的影响,各种科学问题、技术证据、鉴定意见呈现于法庭,法官在审判案件中由于知识和经验的局限性而难以判断,在此背景下专家辅助人制度应运而生。英美法系有专家证人制度,存在完善的以交叉询问为主的专家证人出庭质证规则,大陆法系国家和地区有诉讼辅助人制度,虽然立法中没有明确的出庭质证规则,但是有完善的鉴定人出庭质证规则。我国当前专家辅助人出庭质证规则没有明确的规定,但准用证人出庭质证规则。不过目前缺乏进一步的理论阐述,且简单直接适用也存在问题,同时缺乏系统的、具体的、具有可操作性的质证规则。对此笔者提出构建专家辅助人出庭质证规则的建议。 相似文献

脑损伤后普遍存在的炎性反应激活补体并通过多种途径导致和加重继发性脑损伤。膜攻击复合物具有直接破坏血脑屏障、促使红细胞溶解、促进释放细胞因子、氧自由基和金属基质蛋白、加剧炎症反应的生物特性,从而加重继发性脑损伤。本文对膜攻击复合物造成继发性脑损伤的研究进行综述,希望能对相关研究和法医学鉴定提供参考。 相似文献

The use of digital technologies, functioning thanks to data processing, has been conquering many sectors of the world economy and it is possible that, in the near future, only a few markets will still be excluded from this industrial revolution. Therefore, even if one chose unreasonably to disregard the many innovations that the digital economy has brought about, its development seems quite inexorable, although it is true that this new stage in human progress raises some concerns. In particular, many worry about the millions of passive and powerless digital consumers who, facing a few huge and influential companies without any education or awareness, could succumb and find themselves poorer, victimized, and manipulated. The paper proposes to react to this state of affairs without further fueling the fear of the digital revolution and without the thought that regulation can be used only as a shield to protect fragile digital consumers. Rather, by taking inspiration from some regulatory actions undertaken by the European Union, the paper bears in mind that regulation can be used as a sword in the hands of consumers to finally assign them a lead role in digital markets. New rules to empower consumers and to make them take autonomous and independent decisions as to the management of their personal data as well as to the merits of digital firms can be envisaged. After all, one of the cultural roots of Western societies is that every individual should be enabled to be faber ipsius fortunae. 相似文献

Coarctation of the aorta (CA) is diagnosed mainly in pediatric patients, and therapy is conservative if asymptomatic, but surgical treatment is required if advanced arterial hypertension is present. Moderate to severe forms contraindicate any type of physical activity requiring cardiac effort. Here, we describe the first documented death of an apparently healthy 35-year-old woman because of cardiac tamponade by rupture of an aortic aneurysm, possibly related to congenital CA, prolonged use of oxymetazoline hydrochloride, and physical and/or emotional stress during sexual activity. Our patient was asymptomatic for classical CA symptoms. The patient's breathing difficulties likely in hindsight were due not so much to nasal congestion, but rather to an ineffective oxygenation of the blood from the abnormal heart. In an attempt to treat the "nasal disease," the patient ingested chronic and excessive doses of decongestants, aggravating her fatal disease. The danger of inhaling large doses of nasal decongestants without an appropriate medical indication is highlighted here. 相似文献

In the case of unidentified bodies the estimation of the period since death or of the season of death plays an important role to focus the attention on a reduced number of people among the ones reported missing. Forensic entomology can be one of the most important methods for these estimations, as occurred in this case. Flies are typically the first insects to colonize a dead body. The case reported here concerns the colonisation by insects of a male body in advanced decay found during the winter in Central Italy. This case is of particular interest as few data are available on the entomological evidence in the cold season. In particular, in this case we recovered Calliphora loewi (Calliphoridae), a species never collected before on dead bodies in Southern Europe. Larvae of the black soldier fly Hermetia illucens (Stratiomyidae), pupae and larvae belonging to genus Hydrothea (Muscidae), and Necrobia rufipes (Cleridae) specimens were also collected. The estimated PMI enabled identification of the cadaver, confirmed by DNA analysis. 相似文献
