Dickey–Fuller Type of Tests against Nonlinear Dynamic Models*

In this paper, we introduce several test statistics testing the null hypothesis of a random walk (with or without drift) against models that accommodate a smooth nonlinear shift in the level, the dynamic structure and the trend. We derive analytical limiting distributions for all the tests. The power performance of the tests is compared with that of the unit‐root tests by Phillips and Perron [Biometrika (1988), Vol. 75, pp. 335–346], and Leybourne, Newbold and Vougas [Journal of Time Series Analysis (1998), Vol. 19, pp. 83–97]. In the presence of a gradual change in the deterministics and in the dynamics, our tests are superior in terms of power.     

Customers’ ways of making sense of a financial service relationship through intersubjective mirroring of others

The importance of relationships between buyer and sellers in marketing research is well established. This study contributes to relationship marketing (RM) research as it examines the microfoundations of financial service buyer and seller relationships. The study uses intersubjective theory and a qualitative method with the purpose of conceptualising the qualitatively different ways customers experience face-to-face interactions with a service provider. An empirical study is conducted to determine, based on the customer's own words, what is experienced in the interaction between the customer and the provider. Findings from the empirical material show that not all personal interactions between customers and a service provider, in this case a bank, can be labelled as relationships. Instead, what customers do perceive as a relationship is an encounter where the interaction entails symmetry in the way the customer and the provider mirror each other. When customers receive a treatment in opposition to an expectation of intersubjectivity, they will not refer to the situation as a relationship and, subsequently, according to the underlying assumptions of RM, do not willingly engage in further business with the provider.     

High‐Performance Management Practices and Employee Outcomes in Denmark

High‐performance work practices are frequently considered to have positive effects on corporate performance, but what do they do for employees? After assessing the correlation between organizational innovation and firm performance, this article investigates whether high‐involvement work practices affect workers in terms of wages, wage inequality and workforce composition. The analysis is based on a survey directed at Danish firms matched with linked employer–employee data and also examines whether the relationship between high‐involvement work practices and employee outcomes is affected by the industrial relations context.     

The Survival of New Products

We study the survival of new products in a market with horizontal product differentiation and rapid product turnover. Our data set consists of monthly sales for all new products in the Swedish beer market during 1989–1995. Results show that products with low and decreasing market shares have high hazard rates. The hazard rates are also dependent on firm characteristics; products from firms with the largest market shares face a greater risk of being withdrawn. We argue that high hazard rates of new products can help to explain high failure rates of new firms.     

Information sufficiency and attribution of responsibility: predicting support for climate change policy and pro-environmental behavior

This study extends the central part of the risk information seeking and processing model to examine how message elaboration influences individuals’ support for climate change mitigation policy and their intention to engage in pro-environmental behavior. Data were collected through online experimental surveys at two large universities in the Northeastern United States. Results indicate that perceived issue salience triggered negative affect and information insufficiency, both of which prompted systematic processing, which subsequently led to greater policy support and stronger intention to adopt more pro-environmental behaviors. From an applied perspective, this study suggests important pathways to encourage greater message elaboration, which may lead to increased public support for mitigation policies and adoption of pro-environmental behavior.     

Eriksson on Critical Realism: a rejoinder

Abstract

In this response to Andrew Mearman I argue that his critique suffers from a series of misrepresentations of my paper. For example, Mearman generalizes my arguments about Keynes to be about Critical Realism (CR), and he challenges my criticism of Tony Lawson's arguments by claiming that I have misrepresented CR. In fact the text of my 1998 paper does not support Mearman's claims. Furthermore, since (i) the principal aim of my paper was to question the interpretation of Keynes as a realist, and (ii) Mearman does not present any arguments suggesting how CR in its current form would refute my conclusions, his criticism must be judged doubly misdirected.     

Economic Growth, Inequality, Democratization, and the Environment

We augment the Stokey (1998) model by allowingagents to differ with respect to environmentalquality and income in order to analyze theimpact of income and environmental inequality,and of democratization on aggregate pollution.We find that the impact of a more equal incomedistribution depends on the degree ofdemocracy. In a complete democracy a more equalincome distribution generates, ceterisparibus, less pollution, which is consistentwith indirect empirical evidence, whereas theopposite is the case if democratic rights arehighly restricted. Furthermore, ademocratization is argued to typically lowerboth the income and the environmental qualityof the median voter. In this case, if, inutility terms, the fall in environmentalquality is worse than the fall in consumptionthe median voter decides to tightenenvironmental legislation so that aggregatepollution decreases.     

Go boldly!: Explore augmented reality (AR), virtual reality (VR), and mixed reality (MR) for business

It is not surprising that managers find it hard to distinguish similar-sounding, IT-based concepts such as augmented reality and virtual reality. To many, all of these constructs mean nearly the same and, as a result, the terms are often used interchangeably. This confusion holds back those eager to explore the different opportunities these new technologies present. This Executive Digest presents six different types of reality and virtual reality—(1) reality, (2) augmented reality, (3) virtual reality, (4) mixed reality, (5) augmented virtuality, and (6) virtuality—as part of our actual reality/virtual reality continuum. We then illustrate their differences using a common example and outline business applications for each type.     

Price Adjustments by a Gasoline Retail Chain

We use daily data to examine price responses in the Swedish gasoline market to changes in the Rotterdam spot price, exchange rates and taxes. The distribution of price adjustments by a leading retail chain, for the period January 1980 to December 1996, is symmetric with no small adjustments. An error correction model shows that, in the short run, prices gradually move towards the long-run equilibrium in response to cost shocks. There is some evidence that, also in the short run, prices are stickier downwards than upwards. Prices respond more rapidly to exchange rate movements than to the spot market price. Our analysis emphasizes that to fully understand price adjustments it is necessary to examine data sets where the sample frequency at least matches that of price adjustments.
