Trade policy substitution: theory and evidence

Review of World Economics - With the help of a political economy model, we show that the extent of ‘trade policy substitution’—namely, substitution of tariffs with non-tariff...     

VALUATION OF BARRIER OPTIONS VIA A GENERAL SELF‐DUALITY

Classical put–call symmetry relates the price of puts and calls under a suitable dual market transform. One well‐known application is the semistatic hedging of path‐dependent barrier options with European options. This, however, in its classical form requires the price process to observe rather stringent and unrealistic symmetry properties. In this paper, we develop a general self‐duality theorem to develop valuation schemes for barrier options in stochastic volatility models with correlation.     

The average consumer, the unfair commercial practices directive, and the cognitive revolution

This article examines the merit of the test of the average consumer as a basis for judicial and regulatory action. In the first part, we describe the origin of the test, its application in the Unfair Commercial Practices Directive and its possible developments. In the second part, we discuss the theoretical grounds of the average consumer test (i.e., information and rationality), drawing upon the studies of cognitive psychology and behavioural economics concerning consumers’ behaviour. The result of our analysis is that we call into serious question the practical workability of the test of the average consumer, which requires consumers an overly demanding standard of rationality and information without dedicating much attention to the real functioning of consumer behaviour. The average consumer may be described as an interesting, anti-paternalistic and, to some extent, useful notion. It is, however, an overly simplistic concept with little correspondence with the real world of individual consumer behaviour and should be reinterpreted more flexibly, or even abandoned to mirror consumer behaviour more effectively.

On the risk premium in Nordic electricity futures prices

This paper examines empirically the relationship between electricity spot and futures prices, by analysing a decade of data for a set of short term-to-maturity futures contracts traded in the Nordic Power Exchange. It is found that, on average, there are significant positive risk premiums in short-term electricity futures prices. The significance and size of the premiums, however, varies seasonally over the year; whereas it is greatest during winter, it is zero in summer. It is also found that time-varying risk premiums are significantly related to unexpectedly low reservoir levels. Furthermore, before the unprecedented supply-shock that hit the market around the end of year 2002, the risk premiums were related to the variance and the skewness of future spot prices.     

Risk management and reinsurance strategies in the Spanish insurance market (1880–1940)

Reinsurance allows insurance companies to diversify their risks. However, from this original role, insurance companies have developed various reinsurance strategies in order to expand their market share. From the last decades of the nineteenth century to the 1940s, Spanish insurance companies used reinsurance in a largely unregulated context. This article analyses the reinsurance practices and their adaptation to the singularities of the Spanish market, namely: the difficulties for the consolidation of a core of pure reinsurers; the management of reinsurance in the internationalisation process; and the use of reinsurance by mutual societies to overcome their lack of equity capital.     

Third‐person perception and purchase behavior in response to various selling methods

Two studies investigated whether various tactics of personal selling that generate different levels of resistance also produce different degrees of third‐person perceptions. Furthermore, the studies compared third‐person perceptions to the actual influence on behavior. Study 1 showed that more direct and blatant selling methods produce more TPP. Study 2 showed that people tend to underestimate the influence of the more direct method, especially with regard to themselves. The study concludes by identifying the ideal selling method as one in which the customers are asked about their willingness to listen to the sales campaign before they are told about it. This method increases sales and creates satisfied customers. © 2009 Wiley Periodicals, Inc.     

On the short-time behavior of the implied volatility for jump-diffusion models with stochastic volatility

In this paper we use Malliavin calculus techniques to obtain an expression for the short-time behavior of the at-the-money implied volatility skew for a generalization of the Bates model, where the volatility does not need to be a diffusion or a Markov process, as the examples in Sect. 7 show. This expression depends on the derivative of the volatility in the sense of Malliavin calculus. E. Alòs’ research is supported by grants MEC FEDER MTM 2006 06427 and SEJ2006-13537. J.A.

Estimating the term structures of corporate debt

This paper investigates the corporate bond market by estimating monthly interest rate term structures for investment grade credit classes using both S&P's and Moody's ratings. Term structures are modeled by a piecewise constant forward rate curve and estimated on noncallable coupon paying bonds issued by industrial firms. The iterative estimation algorithm minimizes the sum of squared errors between market prices and model prices while identifying and removing outliers from the sample. Although the forward rate model is successful at pricing corporate debt, additional factors are found to be significant at explaining the residual price error that remains after the forward rate model is fit to market prices. Six necessary no-arbitrage conditions are derived for the term structures of risky and risk-free debt. Occasionally, some of these no-arbitrage conditions are violated and a few violations are asymptotically statistically significant. Finally, trading strategies that capture mispricing in the corporate debt market and violations of no-arbitrage bounds are discussed.This paper was adapted from my dissertation, completed at Cornell University. An earlier version of this paper was titled The Term Structures of Corporate Debt. Thanks to participants at the Cornell University finance workshop, Warren Bailey, Peter Carr, Antoine Giannetti, and especially Robert Jarrow for their helpful comments.     

The individual dual needs for assimilation and distinctiveness as a segmentation mechanism: developing the concept among students

The present study proposes that the individual's needs for assimilation and distinctiveness serve as a valuable mechanism for consumer segmentation and suggests that augmenting the List of Values with these dual needs enriches the understanding of consumer responses to marketing strategies. Results of a study using a sample of 536 students in an Israeli university identified five segments with significantly different needs for assimilation and differentiation. These segments showed different preferences for marketing communications and distribution channels in their purchasing decision of a cell phone. Mass media and website usage influenced segments marked by high assimilation, while word of mouth influenced segments characterized by high distinctiveness. Augmenting the List of Values with dual needs based segmentation moderated students’ tendencies to favour/dislike marketing communications and distribution channels.
