Antecedents of emotional attachment of social media users

Emotional attachment has been documented to be an effective basis for consumer loyalty behaviors in many contexts; however, not much has been offered for new service formats enabled by information technology. This study explores the emotional attachment of social media users in terms of personality traits of users and websites. Drawing on literature on brand personality and brand–self congruence, this research proposes that a match between user’s individual personality and the personality traits of the digital artifacts promotes affective connection to social media websites. The social media, to which the user becomes emotionally attached, therefore becomes part of one’s self-definition and representation in the digital world. Self-expressiveness is also investigated as a motivational driver that helps users form such an emotional bond. Individuals with higher motivation to express themselves are more likely to develop an emotional attachment to social networking sites, exhibit loyal behavior, and experience a stronger effect than self-website congruence on emotional attachment. Results of this research provide support to the proposed relationships. Theoretical and managerial implications are elaborated in the discussion.     

Die Erwartungen der Wirtschaft für 2018

The German economy experiences a boom period. The leading economic research institutes upgrade their economic balance for 2017 to a growth rate exceeding two per cent and their forecasts for 2018 are equally positive. This optimism is widespread despite the UK’s exit from the EU, the protectionist tendencies and the difficult coalition-building in Germany. Technological innovations look ahead: manufacturing industry and trade sector have to react to digital transformation — i.e. electro-mobility, autonomous driving, the use of artificial intelligence and the spread of online trading.     

The rise of economics in competition policy: A Canadian perspective

Competition policy in Canada and elsewhere has changed remarkably over the last 50 years—in large measure due to advances in economics. In this article, we trace the impact of developments in industrial organization on the three central areas of competition policy: cartels, single firm conduct and mergers. We focus on Canadian competition policy but draw comparisons with developments in the United States and Europe.     

Incorporating a tracking signal into a state space model

It is a common practice to complement a forecasting method such as simple exponential smoothing with a monitoring scheme to detect those situations where forecasts have failed to adapt to structural change. It will be suggested in this paper that the equations for simple exponential smoothing can be augmented by a common monitoring statistic to provide a method that automatically adapts to structural change without human intervention. The resulting method, which turns out to be a restricted form of damped trend corrected exponential smoothing, is compared with related methods on the annual data from the M3 competition. It is shown to be better than simple exponential smoothing and more consistent than traditional damped trend exponential smoothing.     

Supply function equilibria: Step functions and continuous representations

In most electricity markets generators must submit step-function offers to a uniform price auction. These markets are often modelled as simpler pure-strategy Supply Function Equilibria (SFE) with continuous supply functions. Critics argue that the discreteness and discontinuity of the required steps drastically change Nash equilibria, invalidating predictions of the SFE model. We prove that there are sufficient conditions, offered quantities can be continuously varied, offered prices are selected from a finite set, and the density of the additive demand shock is not too steep, where the resulting stepped SFE converges to the continuous SFE as the number of steps increases, reconciling the apparently very disparate approaches to modelling electricity markets.     

Marketing’s roles in innovation in business-to-business firms: Status, issues, and research agenda

A project funded by the Institute for the Study of Business Markets to develop an understanding of the current state of business-to-business marketing and a research agenda for the field identified a lack of understanding of how the marketing function can or should best contribute to firms’ innovation efforts as the top priority. A workshop of senior academics and research-oriented practitioners explored this topic further, identifying four specific themes: (1) improving customer needs understanding and customer involvement in developing new products, (2) innovating beyond the lab, (3) disseminating and implementing research findings in firms, and (4) marketing’s overall role in innovation. This article defines these themes, sketches the current status of knowledge about each theme, frames practitioners’ issues with them, and proposes research agendas for each theme to move the field forward. The goal is to encourage rigorously executed academic research that can also help firms innovate more successfully.     

Estimating Differential Dynamic Merger Effects on Market Structure and Entry in Related Markets

The U.S. and EU merger guidelines emphasize “ease of entry” arguments but little is known about the dynamic impact of realized mergers on market structure. This study provides insights on this topic with the use of detailed firm-level data on the memory chip market. Our estimation results provide evidence for differential merger effects on market structure. These effects depend on whether the mergers are dominated by market-power or efficiency gains. While efficiency-dominated mergers cause exit, market-power-dominated mergers attract entrants, and these effects are increasing over time. We also find that market-power mergers have a larger effect on entry than efficiency mergers have on exit. Our results show that mergers can reduce the number of potential entrants into related product markets and serve as an instrument to “reduce the likelihood of entry”.

     

Perceived and actual option values of college enrollment

An important feature of postsecondary schooling is the experimentation that accompanies sequential decision making. Specifically, by entering college, a student gains the option to decide at a future time whether it is optimal to remain in college or to drop out, after resolving uncertainty that existed at entrance about factors that affect the return to college. This paper uses data from the Berea Panel Study to quantify the value of this option. The unique nature of the data allows us to make a distinction between “actual” option values and “perceived” option values and to examine the accuracy of students' perceptions.
