The Impact of an increasing share of RES-E on the Conventional Power Market — The Example of Germany

The intermittency of wind power has a decreasing effect on day-ahead spot prices. Data from Germany illustrate this effect and explain the underlying relationships. This short-term price effect leads to an adaptation process in the conventional generation capacity mix. In the long-run, a higher peak load plant share is required to cope with the increasing volatility of the residual demand. The result is an adapted merit-order. This merit-order intersects with an increasingly volatile residual demand curve and leads to a higher price volatility in the power market, which is going to trigger further adaptations. Therefore this article concludes with a list of open research questions, which can be derived from the illustrated relationship. These research questions should be investigated as soon as possible in order to induce the required adaptations in time.     

On tap: Foodservice operators’ perceptions of a wine innovation

An online survey explored foodservice operators’ (N = 57) perceptions of wine-on-tap, a recent trend in the United States. Adopters (39.1%) considered themselves more innovative, willing to take risks, and influential on others’ opinions than nonadopters (60.9%). Foodservice operators who currently offer wine-on-tap utilized interpersonal information sources (e.g., distributors) more frequently than nonadopters. Additionally, adopters perceived wine-on-tap’s characteristics more positively than nonadopters, indicating wine-on-tap was significantly easier to use than bottled wine. Among other implications, networking stood out as an important driver of innovative behavior in the foodservice industry.     

Stakeholders’ Influence and Contribution to Social Standards Development: The Case of Multiple Stakeholder Approach to ISO 26000 Development

We present an empirical investigation on how multiple stakeholders can influence and contribute to a standard development process. Based on the analysis of comments submitted by stakeholders developing ISO 26000 standard for social responsibility, we found no significant differences between the ratio of accepted and non-accepted comments among various stakeholder groups; however, we conclude that industry is the most influential stakeholder due to the volume of the comments. We also present a set of processes that stakeholders follow to influence and contribute to standards development, namely to (1) eliminate issues that are controversial and undesirable; (2) link and integrate the standard into a network of other documents and ISO standards; (3) seek consensus by highlighting areas for further dialogue or by addressing their exclusion from the standards development, (4) reinforce issues that are important; and (5) improve the content of the new standard. In conclusion, we provide a set of propositions about multi-stakeholder standards development and compare multi-stakeholder involvement in standards developed through a new committee established in existing standards setting organization [i.e., Committees within the International Organization for Standardization (ISO)] and through new standards setting organizations established for one specific task (i.e., Forest Stewardship Council). We envisage that our study will be a useful platform to monitor and evaluate future developments of ISO 26000 and other multi-stakeholder standards.     

The effect of advertising on brand awareness and perceived quality: An empirical investigation using panel data

We use a panel data set that combines annual brand-level advertising expenditures for over three hundred brands with measures of brand awareness and perceived quality from a large-scale consumer survey to study the effect of advertising. Advertising is modeled as a dynamic investment in a brand’s stocks of awareness and perceived quality and we ask how such an investment changes brand awareness and quality perceptions. Our panel data allow us to control for unobserved heterogeneity across brands and to identify the effect of advertising from the time-series variation within brands. They also allow us to account for the endogeneity of advertising through recently developed dynamic panel data estimation techniques. We find that advertising has consistently a significant positive effect on brand awareness but no significant effect on perceived quality.

Generalized spatial autocorrelation in a panel-probit model with an application to exporting in China

This paper proposes a generalized spatial panel-data probit model with spatial autocorrelation of the dependent variable, the time-invariant individual shocks, and the remainder disturbances. It proposes its estimation with a Bayesian Markov chain Monte Carlo procedure. Simulation results show that the proposed estimation method performs well in small- to medium-sized samples. This method is then applied to the analysis of export-market participation of 1451 Chinese firms between 2002 and 2006 in the prefecture-level city of Wenzhou in the province of Zhejiang. Empirical results show that two of the three forms of the hypothesized spatial autocorrelation are significant, namely the spatial lag for the dependent variable and the time-invariant firm-specific shocks, but not the time-variant shocks. Ignoring any of these significant spatial effects would lead to misspecification.     

Beyond plain vanilla: Modeling joint product assortment and pricing decisions

This paper investigates empirically the product assortment strategies of oligopolistic firms. We develop a framework that integrates product choice and price competition in a differentiated product market. The present model significantly improves upon the reduced-form profit functions typically used in the entry and location choice literature, because the variable profits that enter the product-choice decision are derived from a structural model of demand and price competition. Given the heterogeneity in consumers’ product valuations and responses to price changes, this is a critical element in the analysis of product assortment decisions. Relative to the literature on structural demand models, our results show that incorporating endogenous product choice is essential for policy simulations and may entail very different conclusions from settings where product assortment choices are held fixed.
