Maxmin expected utility with additivity on unambiguous events

This paper provides a model of beliefs representation in which ambiguity and unambiguity are endogenously distinguished in the maxmin expected utility model of Gilboa and Schmeidler (1989). Specifically, I first extend it by getting a representation of beliefs such that the probabilistic beliefs over each ambiguous event are represented by a nondegenerate interval, while the ones over each unambiguous event are represented by a number. I then suggest a behavioral definition of ambiguity. It provides a choice theoretical foundation for the Knightian distinction between ambiguity and unambiguity.

Measuring the Effects of Event Sponsorship: Theoretical Frameworks and Image Transfer Models

The use of event sponsorship or other types of sponsorship as a means to establish, enhance, or change brand image is a fairly common practice for a variety of organizations. This objective has been identified as one of the two most common goals for organizations to engage in sponsorship programs. The rationale behind the popularity of sponsorship as a marketing tool to achieve image goals is the general assumption that, by linking a brand to an event, the image of the event can be transferred to the image of the sponsor.

Despite the increasing sophistication of event sponsorship and rising academic interest in understanding sponsorship practice, there is still a lack of in-depth understanding of how sponsorship processes work, in particular in what concerns its brand outcomes. The article addresses this issue by documenting, examining, and critically assessing the existing literature. The main explanations of brand image transfer, including theoretical frameworks and models, are presented; empirical research, divided into effectiveness of brand image transfer and the factors affecting such process, is analyzed; and two main issues found in the more recent articles—direction of brand image transfer and multiple sponsorships—are discussed. Finally, existing gaps are identified and research propositions are presented to guide future research.

企业或有事项与资产负债表日后事项比较及例解

或有事项与资产负债表日后事项在证实时间、最终确定的金额、账务处理调整处理以及在企业会计报表中的披露要求等方面存在不同。调整事项在资产负债表日后得到证实之前,是或有事项;或有事项在资产负债表日后至财务报告报出以前得到证实,就是资产负债表日后事项。或有事项对企业经营管理及会计处理都有影响:或有事项直接影响企业的持续经营和发展、掩盖企业真实的财务状况、左右企业经营成果的确认、操纵企业未来现金流量的计量。     

Catastrophe futures and reinsurance contracts: An incomplete markets approach

We present a theoretical methodology for the pricing of catastrophe (CAT) derivatives with event‐dependent and non‐convex payoffs given the price of a CAT indexed futures contract. We do not assume a fully diversifiable CAT event risk, nor do we assume knowledge of the martingale probability measure beyond the futures price. We derive tight bounds on the contract value and present trading strategies exploiting the mispricing whenever the bounds are violated. We estimate the bounds of the reinsurance contract with data from hurricane landings in Florida. Our method is also applicable when there is no futures market but the price of a CAT‐indexed bond is available.
