Consumer evaluation of self-service innovation failure: the effect of brand equity and attribution

The purpose of this study is to examine how, when a self-service innovation fails, customers evaluate different levels of brand equity and how the brand equity effect is moderated by consumer attribution and service recovery. Based on two experimental studies, the results indicate that high-equity brands suffer less from the adverse effects of self-service innovation failures when compared with low-equity brands. However, self-service innovation failures are more detrimental to high-equity brands if they are caused by service providers' internal factors as well as low service recovery.

EXPLICIT SOLUTIONS OF CONSUMPTION-INVESTMENT PROBLEMS IN FINANCIAL MARKETS WITH REGIME SWITCHING

We consider a consumption and investment problem where the market presents different regimes. An investor taking decisions continuously in time selects a consumption–investment policy to maximize his expected total discounted utility of consumption. The market coefficients and the investor's utility of consumption are dependent on the regime of the financial market, which is modeled by an observable finite-state continuous-time Markov chain. We obtain explicit optimal consumption and investment policies for specific HARA utility functions. We show that the optimal policy depends on the regime. We also make an economic analysis of the solutions, and show that for every investor the optimal proportion to allocate in the risky asset is greater in a "bull market" than in a "bear market." This behavior is not affected by the investor's risk preferences. On the other hand, the optimal consumption to wealth ratio depends not only on the regime, but also on the investor's risk tolerance: high risk-averse investors will consume relatively more in a "bull market" than in a "bear market," and the opposite is true for low risk-averse investors.     

The out-of-sample forecasting performance of nonlinear models of regional housing prices in the US

This article provides out-of-sample forecasts of linear and nonlinear models of US and four Census subregions’ housing prices. The forecasts include the traditional point forecasts, but also include interval and density forecasts, of the housing price distributions. The nonlinear smooth-transition autoregressive model outperforms the linear autoregressive model in point forecasts at longer horizons, but the linear autoregressive and nonlinear smooth-transition autoregressive models perform equally at short horizons. In addition, we generally do not find major differences in performance for the interval and density forecasts between the linear and nonlinear models. Finally, in a dynamic 25-step ex-ante and interval forecasting design, we, once again, do not find major differences between the linear and nonlinear models. In sum, we conclude that when forecasting regional housing prices in the United States, generally the additional costs associated with nonlinear forecasts outweigh the benefits for forecasts only a few months into the future.     

Licensing policies for a new product

This paper studies licensing policies for the owner of a new product and addresses their welfare impact in the assessment of market failures. We show that the best licensing policy for the patent holder is fixed fee licensing with an exclusive territory clause. Consumers are also better off with fixed fees but do not prefer the exclusive territory clause. Social welfare is higher under exclusive territories when fixed costs are not too large. As for efficiency, the number of licences in the private market equilibrium falls short of the socially optimal solution. Our analysis discloses that (i) any policy measures aimed at enhancing the diffusion of technology, in terms of the number of licences, would be welcomed and, (ii) the permissive treatment received by licensing agreements with exclusive territories is justified.     

An Exploratory Framework for Analysing International Retail Learning

It is argued that international retail research has overlooked an essential component of the retail internationalization process, notably learning. This paper proposes an exploratory framework that enables the application of learning theory to the study of international retailing. The paper provides a meaningful starting point for developing an overarching framework which would represent one sort of re-conceptualization of the retail internationalization process, and arguably a new perspective for reinterpreting, re-evaluating and refining the existing literature on international retailing. Alongside this exploratory framework, we present a series of research propositions that might serve as an agenda for research into international retail learning. The paper concludes with a summary of the key themes and ways in which the area of international retail learning may be investigated.     

Service Recovery Efforts in Fast Food Restaurants to Enhance Repeat Patronage

Abstract

The purpose of this study is to: (a) identify service failure incidents; (b) identify service recovery efforts; and (c) determine the effects of resolution levels repeat patronage. Employee service behavior and monetary rewards were found to have a significant effect on resolution levels. The manager should provide guiding principles to improve service quality. Furthermore, mentoring and empowerment may improve employee service performance. Complete resolution leads to repeat patronage. The study found significant relationships between demographic characteristics with service failures and service recovery efforts. Lastly, there were significant relationships between the critical service failures and service recovery efforts and types of fast food restaurants.

The influence of guarantees,active requests to voice and failure severity on customer complaint behavior

Anecdotal evidence suggests that service guarantees and requests by service workers to complain encourage customers to voice following failure, while holding negative word of mouth and exit at bay. However, empirical support for these tactics is limited. To address this deficiency, we conducted an experiment examining the influence of these devices on customer complaint behavior (CCB) across restaurant failures of varying severity. Findings suggest that offering a guarantee, regardless of it being unconditional or combined, encourages voice. Failure severity had the strongest influence on CCB, and it interacted with both active request and guarantee type in influencing exit. Theoretical and managerial implications of the findings are discussed.
