Traditional life insurance products, in particular participating life insurance contracts, are often criticized. Their performance is often said to be poor compared to other investment alternatives. Interestingly, this perception appears to persist although very little research has been conducted into the performance of participating life insurance contracts. But are participating life insurance contracts actually bad for policyholders? We conduct a performance analysis based on contracts offered in the German market, in order to provide evidence to support decision making by policyholders.  相似文献

This article evaluates Tourinho's (1979b Tourinho, O. A.F. 1979b. “The valuation of reserves of natural resources: an option pricing approach”. Berkeley: University of California. PhD thesis [Google Scholar]) work as one of the earliest contributors to the real options literature. His model pioneered the application of risk neutrality to uncertain investments, but his originality of introducing an option-holding cost albeit to overcome the extraction paradox is rarely imitated. We claim that the combination of a convenience yield and an option-holding cost produces a more satisfying representation. Moreover, variations in the holding cost give rise to a host of investment decisions ranging from the standard real option solution for a zero-holding cost to a net present value solution for an infinite-holding cost. Not only does the holding cost mediate between these two poles, but it provides the option seller (usually a landowner or a government) with a policy instrument for influencing the extraction timing and thus the extraction profit of the option buyer. We derive the holding cost that optimizes the landowner's combined value of the option premium, holding costs and eventual royalties.  相似文献

Industrial design (ID) undergraduate education in China is seen as a new rapidly growing discipline over the past 40 years. China’s ID education is not well known in the West due to several barriers: language, the Great Firewall of China which blocks out most of the Western websites and a 12-h time difference. All Chinese ID curriculum and program information are available in Mandarin. The Ministry of Education administers all Chinese design education as well as ID scholarships and faculty exchange grants and its website and documents require translation. The Great Firewall of China blocks 90% of Western websites including Google making it difficult for Western Scholars to access accurate information about the size and shape of the Chinese ID education landscape. China has a historical relationship between the ID schools in China and the United States. Chinese students are studying or alumni of every American ID program. China and USA share similar program types, dual-track admissions for art and design streams, and academic calendars. In this paper, a model was developed to clarify the features of ID undergraduate education in China and USA, and a survey of eight ID schools was processed. Four aspects were comparatively discussed: (1) types of ID education, (2) ranking, evaluation, and certification of ID schools and programs, (3) curriculum, credits, course features, and yearly schedules of schools, (4) influences coming from the culture and globalization process. Based on the analysis, the similarities and differences in ID undergraduate education between the two countries are discussed. Results show the dual-track modes in China and USA are different. It is mainly reflected in the management and enrollment, curriculum organization, and cultural environment. Implications for the localization, openness, and globalization to ID education are finally discussed together with several directions for future development. The findings are valuable to USA and Chinese ID departments and faculty, researchers, staff and visiting scholars. It is also useful for university administrative units such as registrars, admissions, international offices and exchanges to understand each other.

Following Thomas (1969, 1974) the depreciation adjustment charged against accounting earnings is nowadays commonly presumed to be entirely arbitrary when it is viewed from a measurement perspective. This paper develops a statistical interpretation of accounting measurement to show that the depreciation calculation need not necessarily be viewed as incorrigible in Thomas's sense. A probability modelling approach is adopted to illustrate how the depreciation adjustment can be used to smooth accounting earnings over time. Depreciation is thus shown to have potentially useful estimation properties. The results have obvious policy implications regarding the objectives that depreciation and other accounting allocations might serve. They also have a bearing on fundamental questions regarding the nature of accounting measurement.  相似文献

A unique database on individual proposals is used to analyse competition among consulting firms (CFs) for international projects. CFs, which sell services based on human capital, focus on developing countries when operating abroad and, thereby, are highly dependent on development agencies (DAs). The DAs have strict tender rules and claim that skill and experience are the most important factors when proposals are evaluated. Both economic theory and the results of the estimations suggest, however, that long-term relationships (LTRs) between the CFs and the clients are at least as important as traditional skill and experience factors. The LTRs are here measured by means of information about whether the CF has previously worked for the client (repeat purchases) or has visited the client. The results indicate that the client in some cases has pre-decided which CF to select. The client invites several CFs to compete for the tender anyway, either because he is forced to do so by the financier, or because he wants to subject an old supplier to competitive pressure. As the tender rules do not seem to be followed, a policy implication would be that the DAs can skip, or at least relax, their strict tender rules, or strengthen the sanctions associated with violations of the rules.  相似文献

We investigate second-best, input-based taxes foragricultural nonpoint pollution control when marketprices are endogenous and production isheterogeneous. Theoretically, we derive the optimalforms of taxes which take account of heterogeneity(non-uniform taxes) and a tax which does not (auniform tax). Empirically, we use a multi-factor,market-equilibrium simulation model to determineoptimal tax rates and associated equity effects,particularly differences in landowner gains/lossesacross a heterogeneous region. When market prices areendogenous, second-best tax policies result inpecuniary externalities that affect existingenvironmental externalities. In particular, thepecuniary externalities amplify the effect of producerheterogeneity on determination of sub-regionaldifferences in tax rates and returns to land,particularly for the uniform policy. With endogenousprices, the uniform tax rate is considerably higherthan any of the non-uniform rates and, ironically, thenon-uniform taxes result in less dispersion oflandowner gains across sub-regions than the uniformtax.  相似文献

We extend Godambe's famous nonexistence theorem to classes of linear calibrated estimators. We also propose a new method for comparing sampling strategies in the design‐based framework without recourse to simulation.  相似文献
