The effect of incentives on customer evaluations of service bundles

Effects of service bundle incentives on perceived value, search intentions, and switching intentions are assessed in two independent studies. The first study demonstrates that service bundling influences switching and search intentions through perceived value. Results related to bundle incentives support the salience of the convenience associated with consolidating charges onto one bill. Further analysis reveals that explicit valuation of savings creates higher perceived value than convenience alone; however, search and switching intentions are unaffected by incentives or valuation thereof beyond the convenience effect. A second study replicates key parts of these results. Research and practical implications are discussed.     

Higher-order improvements of the parametric bootstrap for long-memory Gaussian processes

This paper determines coverage probability errors of both delta method and parametric bootstrap confidence intervals (CIs) for the covariance parameters of stationary long-memory Gaussian time series. CIs for the long-memory parameter _d0$d_0$ are included. The results establish that the bootstrap provides higher-order improvements over the delta method. Analogous results are given for tests. The CIs and tests are based on one or other of two approximate maximum likelihood estimators. The first estimator solves the first-order conditions with respect to the covariance parameters of a “plug-in” log-likelihood function that has the unknown mean replaced by the sample mean. The second estimator does likewise for a plug-in Whittle log-likelihood.     

Customer readiness to co-production of mobile banking services: a customer-only co-production perspective

This paper aimed to identify the antecedents and corollary of customer readiness for co-production in customer-only co-production services using mobile banking services as a context. Using a structured questionnaire, data were gathered from a sample of mobile banking customers in Ghana and the UK and the data analysis was facilitated by structural equation modelling. From the findings, the antecedents were customer socialisation, customer self-efficacy and customer motivation and the corollary was service productivity. The findings provide managers of customer-only co-production or technology-based services particularly mobile banking services with the specific factors that can be managed strategically and tactically to enhance customer readiness for co-production and service productivity. This study is one of a kind to conceptualise and empirically identify the antecedents and corollary of customer readiness for co-production within the customer-only co-production context. However, as the study was limited to mobile banking services, future studies might test the research model in other customer-only technology-based services.

     

Ethical Leadership and Subordinate Outcomes: The Mediating Role of Organizational Politics and the Moderating Role of Political Skill

This paper posits that ethical leadership increases important organizational and individual outcomes by reducing politics in the workplace. Specifically, we propose that perceptions of organizational politics serve as a mechanism through which ethical leadership affects outcomes. We further argue that the modeled relationships are moderated by political skill. By means of data from 136 matched pairs of supervisors and subordinates employed by a state agency in the southern US, we found support for our predictions. Specifically, we found that perceptions of organizational politics fully mediated the relationship between perceptions of ethical leadership and helping and promotability ratings. In addition, political skill was found to moderate the direct and indirect effects.     

Do foreign workers reduce trade barriers? Microeconomic evidence

This paper provides evidence that foreign workers reduce firms’ trade costs and thus increase the probability that firms export. This informs both the literature on trade costs and the microeconomic literature on firms’ export behaviour. We identify the nationality of each worker in a large sample of German establishments and relate this to the exporting behaviour of these establishments. We allow for the possible endogeneity of an establishment's workforce by instrumenting the share of foreign workers with the regional distribution of foreign workers in the wider labour market. We find a significant effect of worker nationality on exporting which is not driven by the industrial, occupational or locational concentration of migrants. The effect is much stronger for senior occupations, who are more likely to have a role in exporting decisions by the establishment. The relationship is also stronger when we consider exports to particular regions and workers from these regions, consistent with a gravity model in which trade flows from country i to j are a function of migrants from j in i.     

Measuring customer equity and managing the customer asset: an explanatory study in the Australian hotels

Although there are a range of conceptual and theoretical studies about customer equity (CE) measurement and management in the literature, there are few empirical studies where these two concepts are examined together. This paper focuses on the need for a more synthesised approach and addresses calls for more research into this specific area of marketing management. A conceptual framework was developed that synthesises both customer lifetime value and customer relationship management from a customer equity management (CEM) perspective. The framework was used to empirically examine how four CE strategies, together with a firm’s use of the two types of customer data (aggregated and disaggregated), impact on CEM outcomes. Data were collected from 114 hotel managers in Australia and analysed through a decision tree methodology. The results show that hotels are utilising their CE strategies for acquisition purposes more than retention purposes (customer asset management), which overall appears to satisfice more than maximise their hotel’s capacity in achieving effective CE outcomes. The study’s contribution to theory is through empirically testing a framework that combines two discrete theoretical concepts in one study to provide insights to guide future research.     

Performance of conditional Wald tests in IV regression with weak instruments

We compare the powers of five tests of the coefficient on a single endogenous regressor in instrumental variables regression. Following Moreira [2003, A conditional likelihood ratio test for structural models. Econometrica 71, 1027–1048], all tests are implemented using critical values that depend on a statistic which is sufficient under the null hypothesis for the (unknown) concentration parameter, so these conditional tests are asymptotically valid under weak instrument asymptotics. Four of the tests are based on k-class Wald statistics (two-stage least squares, LIML, Fuller's [Some properties of a modification of the limited information estimator. Econometrica 45, 939–953], and bias-adjusted TSLS); the fifth is Moreira's (2003) conditional likelihood ratio (CLR) test. The heretofore unstudied conditional Wald (CW) tests are found to perform poorly, compared to the CLR test: in many cases, the CW tests have almost no power against a wide range of alternatives. Our analysis is facilitated by a new algorithm, presented here, for the computation of the asymptotic conditional p-value of the CLR test.     

Demography and Inflation: An International Study

Changes in the relative share of different age groups in the population may present inflationary, disinflationary, or even deflationary tendencies. We find evidence that increases in the share of the very old (age 80 and older) may be associated with deflation. The analysis is based on an international dataset over a long period. Classifying age groups into young, working, younger old, and older old, we find that the shares of the young and the younger old groups are inflationary, while those of the working group are disinflationary and those of the very old group seemingly deflationary.
