Testing prospect theory in airline demand

The article tests for the existence of reference dependence, loss aversion and diminishing sensitivity in airline demand, in the context of price responsiveness amongst low cost, regular and charter airlines. We incorporate the reference-dependent model into a mixed model to control for heterogeneity. The application finds considerable differences between reference and actual prices in decision-making, confirming that reference dependence exists. People react more strongly to price increases than to decreases relative to their reference price supporting the loss aversion phenomenon and that there is diminishing sensitivity for losses only.     

A discrete and a continuous-time model based on a technical trading rule

In this article we propose a model in discrete and continuoustime that incorporates explicitly a technical trading rule inthe specification of the volatility. The proposed discrete-timemodel is an alternative to GARCH-type processes. We derive conditionsfor the covariance and strict stationarity of the discrete-timeprocess and we study the estimation and inference problems.We also analyze the conditions under which the discrete-timeprocess converges in distribution to a diffusion process. Toillustrate the proposed model and compare it with the GARCHspecification, we analyze the daily closing stock prices oftwo major U.S. companies (Microsoft and Oracle), two stock indices(DAX and NASDAQ) and two U.S. Dollar exchange rates (Euro andSterling)     

Processes with volatility-induced stationarity: an application for interest rates

In this paper we propose a refinement of the existing definition of volatility-induced stationarity that allows us to distinguish between processes with drift and diffusion induced stationarity and processes with pure volatility-induced stationarity. We also propose a classification of stationary processes with volatility-induced stationarity according to the volatility that is needed to inject stationarity. Processes with volatility-induced stationarity are potentially applicable to interest rate time-series since, as has been acknowledged, mean-reversion effects occur mainly in periods of high volatility. As such, we provide evidence that the logarithm of the Fed funds rate can be modelled as a local martingale with volatility-induced stationarity.     

Asymmetric rivalry between strategic groups: response,speed of response and ex ante vs. ex post competitive interaction in the spanish bank deposit market

The objective of this study is to examine asymmetric rivalry between strategic groups in a given industry. Two research hypotheses argue for the existence of asymmetric rivalry in the sense that strategic groups of small companies have a greater degree of response but a slower speed of response to the actions of strategic groups of large companies, than vice versa. To test this, we use an ex post approach that examines the news releases published on the strategic actions and reactions of firms. A third hypothesis compares ex ante competitive expectations with ex post asymmetric rivalry between strategic groups. To test this, we compare ex post news on actions/reactions with an ex ante approach that estimates conjectural variations. The empirical application carried out on bank deposits in the Spanish market defines strategic groups in terms of size due to the historical and institutional conditions of the industry (deregulatory change). The results obtained show that rivalry patterns between strategic groups in terms of company size can be predicted as asymmetric in the sense that smaller bank strategic groups have a greater degree of response (Stackelberg ‘leader–follower’ competitive interaction), and a slower speed of response to the actions of larger bank strategic groups than is found the other way around. Moreover, ex ante expectations of aggressiveness on the part of larger strategic groups characterize greater ex post reactions from the smaller‐size strategic groups. Therefore, the size distribution of strategic groups is valuable to research on complex industries with deregulation changes. Copyright © 2005 John Wiley & Sons, Ltd.     

Battle royal in biotechnology: R&D vs. product vs. process innovations

Companies regard innovation as a central element of their business. However, as not all innovation types are the same, the central question is: should their announcements bring about the same effect on performance? This article analyses potential differences in firm value derived from the innovation-type announcements ‘R&;D’, ‘product’, and ‘process’, made by intensive news-generating firms such as biotech companies. The empirical application shows a significantly positive reaction to innovation announcements, with the prospect of future innovation (‘R&;D’ investment announcements) having greater impact on firm value than ‘product’ and ‘process’ innovations. Firm experience also acts as a moderator in this innovation–performance relationship, which is particularly relevant for entrepreneurs who need to develop and send credible signals indicating the value of the firm's intangible assets to the market.     

Sequential choice behavior: Going on vacation and type of destination

The literature of destination choice has so far studied multi-stage decision making processes that are more representative of the general choice behavior of tourists (e.g. going on vacation, going abroad, and destination country). Alternatively, this study proposes a multi-stage decision process to the choice of tourist destination types (going on vacation, coastal character, and urban character of the destination) as these choice sets are more idiosyncratic to tourists who prefer a specific type of tourist destination (e.g. Spain with clear coastal and inland variations). In order to test this multi-stage choice process as well as the sequential order of both decisions, coastal character and urban character, the current study analyses decision processes vs. different hierarchical multi-stage processes (going on vacation and coastal character preceding urban character; and going on vacation and urban character preceding coastal character). The empirical findings support the existence of a multi-stage choice process where coastal character precedes the urban character destination choice. The main implication of these findings is that, given the limited human analytical capability, a hierarchical choice process can be useful to handle the information overload and the complexity inherent to the destination type choice.     

On the distributional effects of commodity taxation

A commodity tax system is inequality reducing if the after‐tax distribution of income Lorenz dominates the before‐tax distribution of income, regardless of initial conditions. This paper identifies necessary and sufficient conditions under which an ad valorem commodity tax system is inequality reducing, shedding light on the role of taxing luxury—as opposed to necessary—commodities in the equalization of after‐tax incomes.     

Celebrity endorsers' performance on the “ground” and on the “floor”

This article analyzes the relationship between two types of performances, one on the ground (of a tennis court) and the other on the floor (of the stock market). The empirical application looks into the tennis player, Rafael Nadal, and his endorsing firms. The findings show a positive reaction in the market value when the tennis player wins matches in the Grand Slams, the intriguing effect being the diminishing sensitivity pattern that such reaction shows and the absence of loss aversion.     

Battle royal: Zero-price effect vs relative vs referent thinking

This article confronts three psychological influences: relative thinking, referent thinking, and the zero-price effect. The experiment conducted in the context of bundles with complementary components, confirms previous evidence around the dominance patterns between relative and referent thinking when the bargain is a discount; however, when the discount is changed to a free product (worth the same as the discount), the zero-price effect arises. Specifically: (1) if actual price coincides with expected price, relative thinking is the norm, unless the zero-price effect appears; (2) if actual price moderately deviates from expected price, referent thinking is superior to any other effects, relative thinking and the zero-price effect; and (3) if the deviation is extreme, a battle royal among influences takes place: relative thinking beats referent thinking as long as the zero-price effect does not appear. If the zero-price effect is present, it will cancel referent thinking and reverse relative thinking.
