Natural Disaster Insurance and the Equity-Efficiency Trade-Off

This article investigates the role of private insurance in the prevention and mitigation of natural disasters. We characterize the equity‐efficiency trade‐off faced by the policymakers under imperfect information about individual prevention costs. It is shown that a competitive insurance market with actuarial rate making and compensatory tax‐subsidy transfers is likely to dominate regulated uniform insurance pricing rules or state‐funded assistance schemes. The model illustrates how targeted tax cuts on insurance contracts can improve the incentives to prevention while compensating individuals with high prevention costs. The article highlights the complementarity between individual incentives through tax cuts and collective incentives through grants to the local jurisdictions where risk management plans are enforced.     

Iterated VaR or CTE measures: A false good idea?

The purpose of this paper is twofold. Firstly, we consider different risk measures in order to determine the solvency capital requirement of a pension fund. Secondly, we illustrate the impact of the time horizon of long-term guarantee products on these capital. We consider a financial market modelled by a common Black–Scholes–Merton model. We neglect the mortality and underwriting risks by assuming that the pension fund is fully hedged against these risks, which allows us to keep understandable and tractable formulæ (the longevity risk will be a part of future researches). A portfolio is built in this market according to different strategies and the pension fund offers a fixed guaranteed rate on a certain time horizon. We begin with well-known static risk measures (value at risk and conditional tail expectation measures) and then we consider their natural dynamic generalization. In order to be time consistent, we consider their iterated versions by a backward iterations scheme. Within the dynamic setting, we show that solvency capital can be expensive and that attention must be paid to the safety level considered.     

Why not fully spend a conditional block grant?

This paper studies a conditional block grant that Dutch municipalities receive for welfare-to-work programs. Many municipalities do not fully use this grant, although programs are beneficial for them. We argue that municipalities incur expenses to use the grant. If these costs are substantial, then it is optimal not to fully use the grant. Based on municipality-specific data on grants and actual expenditures, we estimate that municipalities have to add about 90 cents from their own resources to spend 1 euro of the grant. As a result, the conditional block grant is de facto a closed-ended matching grant.     

Being Arab and American: Understanding Ethnocentric Tendencies for Arab American Consumers

ABSTRACT

Scant research exists on Arab Americans' ethnocentric tendencies towards purchasing American-made products. This study explores the nexus among consumer ethnocentrism, empathy towards local workers, and ethnic identification. We examined ethnic identification, patriotism, dogmatism, and internationalism as potential influences on Arab Americans' ethnocentric tendencies towards purchasing products made in the US. Data were collected from 165 Arab Americans living in Michigan. We found that when Arab consumers felt empathic towards local workers, they were more ethnocentric towards purchasing local products. Arab Americans' ethnic identification neither influenced their ethnocentric tendencies towards American-made products nor their empathic feelings towards American workers. Our study provides key contributions related to minorities' preferences for locally made products.     

FAIR RETIREMENT UNDER RISKY LIFETIME*

A premature death unexpectedly brings a life and a career to their end, leading to substantial welfare losses. We study the retirement decision in an economy with risky lifetime and compare the laissez‐faire with egalitarian social optima. We consider two social objectives: (1) the maximin on expected lifetime welfare, allowing for a compensation for unequal life expectancies, and (2) the maximin on realized lifetime welfare, allowing for a compensation for unequal lifetimes. The latter optimum involves, in general, decreasing lifetime consumption profiles as well as raising the retirement age. This result is robust to the introduction of unequal life expectancies and unequal productivities.     

Hidden costs of supply management in a small market

Canada regulates its dairy and poultry industries through supply management. The supply‐management programs use target prices, production quotas and import tariff‐rate quotas to raise domestic prices. Canadian supply‐managed producers cannot export their output to world markets as exports would be considered subsidized under World Trade Organization rules. In this paper, we show that once foregone export opportunities are accounted for, supply management may no longer be beneficial to domestic producers of the supply‐managed commodities. The extent to which foregone profits from exports dominate domestic rents depends on Canada's comparative advantage, domestic market elasticities and the extent of supply management distortion in the domestic market.     

Career and collaboration patterns in tourism research

Research collaboration has become an important characteristic of contemporary academia and is of prime importance for the academic career opportunities of young scholars. For the purposes of this study research collaboration is a formal manifestation of intellectual collaboration in scientific research and involves the participation of two or more authors in the production of a joint publication. The paper reports the findings of a quantitative online survey sent to tourism scholars to explore their career and collaboration patterns in co-authored publications in tourism research. The results indicate that there are divergent perspectives on research collaboration and that collaboration characteristics change as scholars progress through their careers. The paper proposes a research career lifecycle to explain the patterns in tourism research collaboration.     

Accounting students’ choice of blended learning format and its impact on performance and satisfaction

Using online platforms to deliver educational content, some institutions have developed blended courses that combine the advantages of online instruction with traditional face-to-face (F2F) teaching. This study compares accounting student performance and satisfaction in two blended formats with similar content and design, i.e. F2F+ vs. Online+ courses. It also assesses the characteristics of students who choose the latter option over F2F+ courses. Students in four advanced accounting subjects were surveyed and their course performance was obtained. Results indicate that the main determinants of students’ decision to register for an Online+ course are retaking the course, increased weekly work hours, and belief that this type of blended course facilitates learning. Results show that students in advanced accounting courses with equivalent content and design perform similarly and have the same level of course satisfaction across course delivery formats, as hypothesized under equivalency theory.     

Target volatility option pricing in the lognormal fractional SABR model

We examine in this article the pricing of target volatility options in the lognormal fractional SABR model. A decomposition formula of Itô's calculus yields an approximation formula for the price of a target volatility option in small time by the technique of freezing the coefficient. A decomposition formula in terms of Malliavin derivatives is also provided. Alternatively, we also derive closed form expressions for a small volatility of volatility expansion of the price of a target volatility option. Numerical experiments show the accuracy of the approximations over a reasonably wide range of parameters.
