Growth and Welfare Effects of Tax Cuts: The Case of a Productive Public Input with Technological Risk

This paper analyzes the dynamic impact of tax cuts within a stochastic model of endogenous growth with a congested public input. A decreasing taxation of deterministic income parts leads to the well-known positive growth effect. Nevertheless, due to the insurance effect associated with the taxation of stochastic income flows, the overall growth impact of taxation is ambiguous. It is shown that the optimal structure of financing government expenditure does not only depend on the degree of rivalry but also on the degree of risk aversion. The optimal real value of government debt decreases with a rise in congestion. We identify that in the case of proportional congestion, the base for tax cuts should be the growth neutral consumption tax. Maximizing the growth rate does not automatically coincide with maximizing welfare. Hence, the base for tax cuts gains importance to realize a welfare optimal policy.     

Specification tests in nonparametric regression

Consider the location-scale regression model Y=m(X)+σ(X)?$Y=m(X)+\sigma (X)?$, where the error ?$?$ is independent of the covariate X, and m   and σ$\sigma$ are smooth but unknown functions. We construct tests for the validity of this model and show that the asymptotic limits of the proposed test statistics are distribution free. We also investigate the finite sample properties of the tests through a simulation study, and we apply the tests in the analysis of data on food expenditures.     

A Psychological Contract Perspective of Expatriate Failure

The expatriate literature needs to move beyond maladjustment as a primary reason for expatriate failure. This article draws on the psychological contract as a valuable lens to observe changes in expatriate behavior that may determine expatriate success or failure on international assignments. Prior research on the expatriate psychological contract has focused solely on an expatriate's social exchange relationship with the assigning parent company. This article offers a dual‐foci perspective of the expatriate psychological contract and suggests that expatriates’ perceptions of psychological contract breach arise from two sources—the assigning parent company and the receiving host company. The conceptualization of breach with dual foci forms the basis for the proposed model of expatriate failure. The model proposes that differences in expatriates’ contexts will influence their likelihood of perceiving breach and that breach, once perceived, will affect expatriate behavior through its influence on sense‐making, affect, conation, and attitudes. The propositions developed in this article provide a foundation for future theorizing and empirical work on expatriate cognitions of psychological contract breach. © 2016 Wiley Periodicals, Inc.     

Nonparametric least squares methods for stochastic frontier models

When analyzing productivity and efficiency of firms, stochastic frontier models are very attractive because they allow, as in typical regression models, to introduce some noise in the Data Generating Process . Most of the approaches so far have been using very restrictive fully parametric specified models, both for the frontier function and for the components of the stochastic terms. Recently, local MLE approaches were introduced to relax these parametric hypotheses. In this work we show that most of the benefits of the local MLE approach can be obtained with less assumptions and involving much easier, faster and numerically more robust computations, by using nonparametric least-squares methods. Our approach can also be viewed as a semi-parametric generalization of the so-called “modified OLS” that was introduced in the parametric setup. If the final evaluation of individual efficiencies requires, as in the local MLE approach, the local specification of the distributions of noise and inefficiencies, it is shown that a lot can be learned on the production process without such specifications. Even elasticities of the mean inefficiency can be analyzed with unspecified noise distribution and a general class of local one-parameter scale family for inefficiencies. This allows to discuss the variation in inefficiency levels with respect to explanatory variables with minimal assumptions on the Data Generating Process.

Fine‐tuning what we know about employees' experience with flexible work arrangements and their job attitudes

Prior research has generally found positive relationships between flexible work arrangements (FWAs) and employee attitudes. However, we know relatively little about organizational contingencies that affect the strength of these relationships, as there is little multilevel, multicompany research on FWAs. This study explores three aspects of employees' experience with FWAs—perceived availability of the number of FWAs, different types of FWAs, and actual use of FWAs—and their corresponding effects on employee job satisfaction and organizational commitment. Using a large multicompany data set (1,799 companies, 17,895 workers), we found that employees who perceive more FWAs available to them have higher job satisfaction and organizational commitment, especially in organizations that report offering fewer formal FWA policies. Among different types of FWAs, perceived availability of flexible scheduling is more positively associated with job satisfaction than flexible location and hours, and both flexible scheduling and location are more positively associated with organizational commitment than flexible number of hours. We also found that employees who actually use flexible scheduling have lower job satisfaction and organizational commitment than those who have it available but do not use it. The theoretical contributions and practical implications of these findings are discussed.     

Customer complaint behaviour (CCB) in the retail sector: why do customers voice their complaints on Facebook?

With the increasing usage of platforms such as Facebook, understanding customer complaint behaviour (CCB) in the context of the social media is imperative for any businesses. Of the two billion users on Facebook, more than half of its users have shared their product-related experiences with others on the platform. This paper aims to explore CCB in the context of social media in regards to customers’ unfavourable buying experiences in the retail sector. A qualitative research approach and 12 in-depth interviews were conducted. The findings indicate that the respondents’ initial contact with the retailer directly resulted in service recovery failures and undesirable outcomes. Such double deviation then leads to frustration and uncertainty of the situation, which furthermore led to the respondents’ need to voice their complaint by sharing their unfavourable experiences on Facebook. The main reasons for the respondents to voice their complaints on the platform is to vent frustration, to share their unfavourable experiences, a need to be seen, understood and respected, to seek revenge by damaging the retailer’s reputation as well as offering the retailer a chance to improve. A proper way to manage complaints, in which frontline employees can solve the problem before the customers feel the need to turn to the social media, is crucial. However, once the complaints are voiced on Facebook, it is imperative to respond to the complaints and acknowledge the problem rather than ignoring the situation.     

Farmer perceptions of legumes and their functions in smallholder farming systems in east Africa

Legumes play an important role in sub-Saharan Africa (SSA) farming systems through the provision of food, feed, fuel, income and a range of biophysical benefits, such as soil fertility enhancement and erosion control. However, their full potential is not being realized. The purpose of this study was to assess farmers’ perceptions and knowledge towards legumes and the rationale of farmers for current legume production practices using a survey of 268 farmers in the Democratic Republic of Congo and Kenya. Most of the farmers had some knowledge of legumes and their characteristics. However, they had little knowledge of some key functions, including soil erosion control and soil fertility improvement. Most farmers relied on radio and other farmers for legume-related information. Farmers with relatively large livestock holdings ranked provision of livestock feed as an important legume function. We conclude that farmers put more value on short-term benefits of legumes including food and income than long-term benefits such as natural resource management and thus grain legumes are more readily identified by farmers than forage species. Also, we conclude that farmers require more than just information about legumes to increase uptake, they also require improved market access to procure inputs and sell products to realize other benefits that are associated with growing legumes.     

Instability of the Inflation–Output Trade‐Off and Time‐Varying Price Rigidity

This paper studies the time instability of the Phillips curve by paying particular attention to the inflation environment and price stickiness. We identify various inflation episodes and investigate the changing nature of the curve across these periods for five advanced countries over 1960–2013. We show that the mean inflation, the slope of the curve and the threshold mean inflation that erodes price rigidity are time varying. The inflation environment is a key determinant of the inflation–output relationship, rejecting the evidence of a flat curve and restoring the inflation–output trade‐off above certain inflation thresholds.
