Simple sufficient conditions for the existence of a unique equivalent martingale measure are provided. Furthermore, these
conditions give us a handle on situations where an equivalent martingale measure cannot exist. The existence of a unique equivalent
martingale measure is of relevance to problems in mathematical finance. Two examples of models for which the question of existence
was unresolved are studied. By means of our results existence of a unique equivalent measure up to an explosion time is proved. 相似文献

This paper applies principles of transition to land tenure and squatting in South Africa. Political transition in South Africa reassigned political property rights, which produced contestable, and rent‐seeking incentives for squatting as a means to privatize land and redistribute wealth. Government failure to establish and protect private property rights in a squatter camp resulted in common‐pool problems that resisted private and public resolution with consequent rent dissipation and social loss. In response to this retreat from duty, informal agents emerged to claim their own share of the prize. Without enforceable rules of capture, the growth of squatter camps in South Africa will continue.

Based on a contingent perspective of accounting change, this paper reviews the historical development of differential reporting in Germany, by drawing on primary and secondary sources. The main objective of the paper is to shed light on the driving forces and main influential parameters that have shaped the existing differential reporting framework. This historical approach supplies interesting insights for the current discussion on differential reporting in Germany produced by the EU Regulation on the application of International Accounting Standards. 相似文献

Rent control is an economic abomination. It diverts investments away from residential rent units, it leads to their deterioration, it is responsible for urban decay such as in the South Bronx, it does not help poor tenants, it is a horrendous means of income redistribution. Yet this economic regulation is beloved of intellectuals (hot beds of pro rent control sentiment are Berkeley, Ann Arbor and Cambridge) particularly in the legal and philosophical communities. The present article is dedicated to an exploration and rejection of the arguments in behalf of rent control which emanate from this source. 相似文献

I model imperfect information, derive a downward sloping market demand curve, and explain vacancies in a partial equilibrium model of a rental housing market. Tenants can be completely described by an exogenous demand curve, perhaps arising from differences in income, preferred location, or tastes, and view vacant units based on a stochastic arrival of rental information. Free entry of these landlords induces excess rental housing capacity (equilibrium vacancies). I determine the equilibrium distribution of rents for vacant units, show that this rent distribution may be discontinuous, and explore the equilibrium vacancy rate to changes in exogenous parameters. The resulting characterization of equilibrium distributions of rents may be amenable to econometric modeling exploring the relationship between market rents and vacancies. 相似文献

行业间工资差异和垄断租金分享 总被引:4,自引:0,他引:4
史先诚 《上海财经大学学报(哲学社会科学版)》2007,9(2):66-73
以产业门类为基准测算的中国行业间工资差异明显且自1988年以来呈现逐步上升趋势,随着产业细分,行业间工资差异进一步提高。对劳动市场工资决定的理论分析表明,行业间工资差异主要源于各行业就业人员的人力资本差异和可能的垄断租金分享。实证研究中发现,就业人员性别、年龄和教育等就业人员特征只能解释行业平均报酬变差系数的60%左右,其余部分源于垄断行业的租金分享。其中,技术/知识型市场垄断行业租金分享比例不高,但非竞争性垄断行业普遍获得了超额报酬,约占其行业高工资的50%以上。后者超额报酬和超水平高福利主要源于相关行业无偿或低成本的自然资源占用和国有资产经营、攫取消费者福利、成本膨胀亏损的财政或社会公众补贴,因此要从其垄断机理和初次分配制度上改革以建立公平收入分配秩序。 相似文献
