Analysen und Berichte

Enste and Wicher suggest that political regulation is always wealth-reducing. However, their analysis neglects various relevant determinants of the wealth indicator. Economic wealth cannot be estimated from the quantity of regulation, as quality and other aspects matter. Hence, political acumen is required. Enste and Wicher reply to criticism of the regulation index and the analysis of the impact of regulation on education. They argue that they neither ignore the positive effects of regulation (taken into account with the data on good governance indicators) nor demand a zero regulation policy. Instead, the main goal of the analysis is to provide an international comparison for “better regulation”.     

The installed base effect: Implications for the management of innovation

Most studies of barriers to the adoption of innovations concentrate on characteristics of the population (consumer or organizational), features of the product, or the marketing mix This paper examines a seldom studied barrier— the installed base of the technology or product being supplanted In order to describe the magnitude of this barrier and to provide recommendations for overcoming it, the Installed Base Effect is examined from three dimensions: supply, demand and market externalities     

Football spectator no-show behaviour in the German Bundesliga

Despite an extensive literature on stadium attendance demand, our understanding of those factors shaping spectator no-show behaviour is rudimentary at best. Here, we explore such behaviour by using a comprehensive two-step approach: First, we examine the determinants of no-show behaviour in the German Bundesliga between the four seasons 2014–15 and 2017–18; Second, because our initial results imply that spectator no-show behaviour is more prominent among season ticket holders (STHs), we exploit additional survey data to understand individual STH no-show appearances better. Our results suggest that club managers interested in reducing the no-show rate should rethink existing season ticket strategies.     

Analyzing determinants of bond yield spreads with Bayesian Model Averaging

This paper analyzes determinants of country default risk in emerging markets, reflected by sovereign yield spreads. The results reported so far in the literature are heterogeneous with respect to significant explanatory variables. This could indicate a high degree of uncertainty about the “true” regression model. We use Bayesian Model Averaging as the model selection method in order to find the variables which are most likely to determine credit risk. We document that total debt, history of recent default, currency depreciation, and growth rate of foreign currency reserves as well as market sentiments are the key drivers of yield spreads.     

The great intimidators

After Disney's Michael Eisner, Miramax's Harvey Weinstein, and Hewlett-Packard's Carly Fiorina fell from their heights of power, the business media quickly proclaimed thatthe reign of abrasive, intimidating leaders was over. However, it's premature to proclaim their extinction. Many great intimidators have done fine for a long time and continue to thrive. Their modus operandi runs counter to a lot of preconceptions about what it takes to be a good leader. They're rough, loud, and in your face. Their tactics include invading others' personal space, staging tantrums, keeping people guessing, and possessing an indisputable command of facts. But make no mistake--great intimidators are not your typical bullies. They're driven by vision, not by sheer ego or malice. Beneath their tough exteriors and sharp edges are some genuine, deep insights into human motivation and organizational behavior. Indeed, these leaders possess political intelligence, which can make the difference between paralysis and successful--if sometimes wrenching--organizational change. Like socially intelligent leaders, politically intelligent leaders are adept at sizing up others, but they notice different things. Those with social intelligence assess people's strengths and figure out how to leverage them; those with political intelligence exploit people's weaknesses and insecurities. Despite all the obvious drawbacks of working under them, great intimidators often attract the best and brightest. And their appeal goes beyond their ability to inspire high performance. Many accomplished professionals who gravitate toward these leaders want to cultivate a little "inner intimidator" of their own. In the author's research, quite a few individuals reported having positive relationships with intimidating leaders. In fact, some described these relationships as profoundly educational and even transformational. So before we throw out all the great intimidators, the author argues, we should stop to consider what we would lose.     

Zur Analyse der Auswirkungen der Biomethaneinspeisung auf die Entwicklung der deutschen Erdgasversorgung

Natural gas offers several advantages compared to other fossil fuels, especially regarding its specific CO₂ emissions and its flexibility in usage. Thus, it is expected that the consumption of natural gas will further increase in the future. Nevertheless, this increase is accompanied by a growing dependence on imports. Biomethane, i.e. conditioned biogenous gas, is an interesting possibility for the substitution of natural gas. As it is a renewable and indigenous energy source, it contributes to the reduction of both: CO₂ emissions and gas imports. Similar to the renewable electricity generation, the German government sets targets for the biomethane feed-in and has introduced promotion mechanisms to achieve these goals. Within this paper the possible role of biomethane in the German natural gas supply has been evaluated by applying the optimising energy flow model PERSEUS-EEM. Results show that the CO₂ emissions trading system by itself is not sufficient for the competitiveness of biomethane. Model results demonstrate that a significant increase of the German natural gas demand can be expected especially due to the stringent CO₂ reduction targets. Even when the political CO₂-reduction targets are reached, biomethane will not play a major role in the natural gas supply of Germany.
