Image feedback effects of brand extensions: Evidence from a longitudinal field study

This paper examines the issue of image feedback effects and potential drivers of these effects by analyzing real-world extensions that have been introduced successfully in the market, using a longitudinal field study. Within the context of typical FMCG extensions, the authors find strong evidence that even for successful extensions, negative image feedback effects can occur, particularly when the perceived quality of the extension fails to meet the quality level of the parent brand. Strong brands tend to be more vulnerable to negative image feedback effects because consumers have a higher reference level for their extensions than for those of weaker brands. The likelihood of negative feedback effects decreases as the level of perceived fit and consumers’ perceptions of the general extendibility of the parent brand increases. But managers cannot, at least in the short run, mitigate negative image feedback effects through increased advertising support. Finally, the findings demonstrate that the feedback effects of a new extension product on parent brand image diminish over time.

Monetary and fiscal policy interactions in a micro-founded model of a monetary union

This paper analyzes in detail the mechanisms behind fiscal stabilization policy and the role of policy commitment in a micro-founded New-Keynesian model of a two-country monetary union, which is hit by supply shocks. We also explore the determinants of the gains from fiscal stabilization. While monetary policy with identical union members is concerned with stabilizing the union-wide economy, fiscal policy aims at stabilizing inflation differences and the terms of trade. Besides exploring optimal policies, we also consider monetary and fiscal rules. We study these rules both under coordination and non-coordination by the fiscal authorities.     

How technology teachers understand technological knowledge

Swedish technology teachers’ views of technological knowledge are examined through a written survey and a series of interviews. The study indicates that technology teachers’ understandings of what constitutes technological knowledge and how it is justified vary considerably. The philosophical discussions on the topic are unknown to them. This lack of a proper framework for what constitutes technological knowledge and how it is justified might affect both how curricula are interpreted and how pupils’ knowledge is assessed.     

The contrary forces of innovation: A conceptual model for studying networked innovation processes

In this paper, we argue that industrial innovation processes can productively be analysed as consisting of two sub-processes that over time create and mobilise contrary forces within both internal and external interactions of the innovation project. One of these forces emerges from the process of mobilising resources, activities, and actors in ensuring commitments to the project over time. The other is the process of explorative learning, which continues to create revised or even new propositions about the realities of the project and its opportunities. We argue that this analytical distinction permits us to expand our understanding of how friction forces develop over time in business networks (Håkansson & Waluszewski, 2001a,b), the patterns of divergence and convergence in innovation processes as identified by Van de Ven et al. (1999) and the processes of “path creation through mindful deviation” as argued by Garud and Karnøe (2001).     

The Role of Irrigation Districts in California's Water Development

Summary: Early settlers found that California had excellent soil and tem-perature for agricultural development, but very scanty rainfall in the growing season. Irrigation was introduced on a small, indi-vidual scale, which developed into organized projects through the pioneering of the irrigation-district system. Legislation was passed for a special tax structure by which revenue for mainte-nance and operation of irrigation projects was obtained by taxing the benefited land exclusive of improvements. This unique tax structure encouraged individual ownership of land in units of the most economic size and spurred intensive cultivation and general economic development.     

Different open book accounting practices for different purchasing strategies

Extant studies of open book accounting focus primarily on data disclosure in long-term, committed purchasing arrangements. We extend research beyond that context by exploring the association between open book practices (in terms of nature and uses of disclosed data as well as conditions of data disclosure) and two different purchasing strategies. Three case studies are performed. Results indicate that within market procurement characterized by a transactional purchasing strategy, cost data primarily serve to reduce purchase price. Therefore, data disclosure is limited in scope and scale, occurs primarily during supplier evaluation and selection, and is characterized by an adversarial atmosphere. Incentives for suppliers to open their books focus on short-term tangible gains. Within a hybrid exchange arrangement characterized by a relational purchasing strategy, data disclosure supports cost reduction, e.g., through joint product development, and is more comprehensive. The atmosphere is less adversarial and suppliers reap long-term benefits.     

The effectiveness of personalized marketing in online banking: A comparison between search and experience offerings

This study reports the results of personalized online promotions in a context where personalization has not been researched before – in online banking. Genuine online bank customers were shown personalized banner advertisements when they logged in to their online bank account. Three financial offerings consisting of different search and experience attributes were promoted to three groups of customers. We examined the attention, elaboration and choice measures, and compared the effectiveness of personalized banners to default banners, and the online promotions to direct-mail promotions. Despite the goal-directed routines that reflect the dominant customer behaviour in online banking, personalized banners attracted more attention than default banners. Furthermore, messages that promote fairly simple search-type offerings that are easy to apply and are linked to the context in which the promotion occurs are more effective than messages that do not fulfil these criteria. The results offer implications both for research and practice.     

Nonlinear modelling of the Finnish Banking and Finance branch index

It is well documented that daily returns of several financial assets cannot be modelled by pure linear processes. It seems to be generally accepted that many economic variables follow nonlinear processes. The sources of nonlinearity can be divided in two classes: those where nonlinearities stem from the conditional variance and those where non-linearities enter through the conditional mean. Efforts in modelling the former have resulted in development of the ARCH-family models. There is, however, less evidence on nonlinearity in the mean of financial time series. One family of models that is applied in finance is the STAR. In this paper some nonlinear modelling techniques are applied to a Finnish financial time series, the daily Banking and Finance branch index on the Helsinki Stock Exchange. The techniques include a variance-nonlinear model from the ARCH family, a mean-nonlinear model, namely Smooth Transition Autoregression (STAR)-model and a neural network. Linearity is tested for by standard autocorrelation tests, LM-tests against the specific nonlinear models and the BDS-test. The study provides supplements to a range of earlier research. It demonstrates that the stock series is both linearly and nonlinearly dependent. Adapting an ARCH(3) eliminates the dependencies most satisfactorily. The ARCH-models and STAR-models were estimated using the SHAZAM-package.

Buyer Subsidies in an Equilibrium Model of Price Dispersion

Abstract. We present a model of equilibrium price dispersion in which a per-unit subsidy to buyers can reduce average prices. The reason is that subsidies have two effects on average prices that work in opposite directions. First, subsidies raise buyers' willingness-to-pay, and by itself this causes firms to charge higher prices. However, since a higher willingness-to-pay lowers the relative cost of search, subsidies also induce more search. This creates a second effect that puts pressure on firms to reduce prices. We show that the second effect can dominate, thus causing an overall reduction in average price.
