We introduce a class of financial contracts involving several parties by extending the notion of a two-person game option to a contract in which an arbitrary number of parties is involved and each of them is allowed to make a wide array of decisions at any time, not restricted to simply exercising the option. The collection of decisions by all parties then determines the contract’s termination date as well as the terminal payoff for each party. We provide sufficient conditions under which a discrete-time multi-person game option has a unique arbitrage-free price, which is additive with respect to any partition of the contract. Our results are illustrated by the detailed study of a particular multi-person contract with puttable tranches. 相似文献

A major debate in microfinance focuses on the existence of a trade‐off between the financial sustainability of microfinance institutions (MFIs) and their outreach to poor clients. This paper adds to this debate by analyzing whether financial and social efficiency are mutually exclusive in a context of implicit subsidies by the state and international donors. We use data from a sample of 28 Vietnamese MFIs and apply Data Envelopment Analysis (DEA) to identify the existence of a trade‐off. Our analysis shows that for Vietnamese MFIs financial and social efficiency are not related. We interpret this as evidence for the fact that there is no support to believe that there is such a trade‐off. Subsidies, based on which most Vietnamese MFIs currently operate, helps them to show high financial efficiency, while at the same time being able to attain their social goals. Nevertheless, this model may not be sustainable in the long‐term. 相似文献

In this article we measure the effects of events on risk and return and analyze the persistence of the influencing variables
on German energy companies. Therefore, we refer to event-study methods by means of the Capital Asset Pricing Model, GARCH-Modeling
and Kalman filters. We find that the discussed events do not affect all companies in an equal manner. Moreover, we show that
the impact on risk and returns is not persistent and does not lead to an increase in the overall systematic risk for the considered
utility operators in Germany. 相似文献

China's recent political and economic inroads into Africa have generated much interest in the current literature, with scholars and policymakers endeavouring to assess the merits and risks implicit in this renewed engagement. Absent from the literature, however, are systematic analyses of African perceptions of these rapidly growing China–Africa links, and what determines these perceptions. This article fills this void by examining not only African attitudes towards China's African presence, but also investigating the considerations that inform these views. Using multi-level modelling techniques, this article estimates the effects of Chinese foreign direct investment (FDI), Sino-African trade and notions of democracy and human rights on African attitudes towards “China-in-Africa”. The results suggest that Africans' views of China are nearly equivalent to those that they hold vis-à-vis Western countries. The perceived impact of imports from China has a negative effect. However, this effect is counter-balanced by perceptions of China's impact on poverty alleviation—in line with its greater focus on economic, social and cultural, as opposed to civic and political human rights—in particular through FDI. Among those who value civic and political human rights, in contrast, attitudes towards China are less favourable. This finding is echoed with respect to democratic governance, though the effect is less stable. The results are derived from Afrobarometer data covering 20 African countries. 相似文献

Occupational licensing currently affects more than 1,000 occupations in the United States. I use confidential US Census Bureau business micro‐data to shed light on the effect of occupational licensing in cosmetology on key market outcomes and study its effect on the providers of occupational training. Occupational licensing regulation does not seem to affect the equilibrium number of practitioners or prices of services to consumers, but is associated with significantly lower practitioner entry and exit rates. I further find states with more stringent licensing requirements to have more instructors and a larger median size of training facilities, suggesting possible barriers to entry for the training schools. Instructors, however, do not earn more in such states. 相似文献

This paper uses Census microdata to examine how starting a business as a franchise rather than an independent business affects its survival and growth prospects. We assess factors that influence the decision to become a franchisee and use various empirical approaches to correct for selection bias in our performance analyses. We find that franchised businesses on average exhibit higher survival rates than independent businesses; but importantly, the difference is small compared with claims in the trade press. The effect is also short lived: conditional on surviving a year or two, we no longer find survival (or growth) differences. We then explore two potential sources for this small survival advantage, namely franchisors’ screening process and the benefits arising from the brand and business know‐how provided by franchisors. We find evidence that both of the sources contribute to the franchising advantage. 相似文献

An interesting research problem in our age of Big Data is that of determining provenance. Granular evaluation of provenance of physical goods (e.g., tracking ingredients of a pharmaceutical or demonstrating authenticity of luxury goods) has often not been possible with today's items that are produced and transported in complex, interorganizational, often internationally spanning supply chains. Recent adoptions of the Internet of Things and blockchain technologies give promise at better supply‐chain provenance. We are particularly interested in the blockchain, as many favored use cases of blockchain are for provenance tracking. We are also interested in applying ontologies, as there has been some work done on knowledge provenance, traceability, and food provenance using ontologies. In this paper, we make a case for why ontologies can contribute to blockchain design. To support this case, we analyze a traceability ontology and translate some of its representations to smart contracts that execute a provenance trace and enforce traceability constraints on the Ethereum blockchain platform. 相似文献
