On the Dynamics of Basic Growth Models: Ratio Stability vs. Convergence and Divergence in State Space

Abstract. We show for a class of basic growth models that convergence in ratios does not imply the pathwise convergence to the corresponding balanced growth path in the state space. We derive conditions on parameters and on the elasticity of the savings function for convergence or divergence and apply our results to the Solow model, an augmented Solow model as well as to an optimal growth model. An implication for the convergence debate is that two economies that differ only in the initial capital stock and converge in per capita terms might diverge to infinity in absolute terms.     

The effects of customer equity drivers on loyalty across services industries and firms

Customer equity drivers (CEDs)—value equity, brand equity, and relationship equity—positively affect loyalty intentions, but this effect varies across industries and firms. We empirically examine potential industry and firm characteristics that explain why the CEDs–loyalty link varies across services industries and firms in the Netherlands. The results show that (1) some previously assumed industry and firm characteristics have moderating effects while others do not and (2) firm-level advertising expenditures constitute the most crucial moderator because they influence all three loyalty strategies (significant for value equity and brand equity; marginally significant for relationship equity), while three industry contexts (i.e., innovative markets, visibility to others, and complexity of purchase decisions) each influence two of the three loyalty strategies. Our results clearly show that specific industry and firm characteristics affect the effectiveness of specific loyalty strategies.     

A Note on the Poll Tax

A poll tax is usually seen as the standard example of a lump sum tax and therefore as allocationally efficient. In this paper, it is shown that in a dynamic setting with endogenous fertility, a poll tax may yield a Pareto‐inferior outcome as compared to a percentage consumption tax.     

Market Reaction to Goodwill Impairments

This paper examines the information content of goodwill write-downs under International Accounting Standard (IAS) 36 (Impairment of Assets) and Statement of Financial Accounting Standards (SFAS) No. 142. We investigate whether the informational value depends on the reliability of the news. Using a sample of 564 goodwill write-down announcements issued from 2005 to 2009, we find a negative capital market reaction to announcements of unexpected goodwill write-offs. Our results indicate that investors react more negatively when a country's level of legal protection is low and allows more management discretion. We further report that market reaction is associated with managers explaining the write-down decision and depends on the verifiability of these explanations. Investors react more negatively when an unverifiable internal explanation is given and less negatively when a verifiable external explanation is provided. We do not find significant differences between write-down announcements under SFAS 142 and IAS 36.     

Shareholder value mining: Wealth effects of takeovers in German coal mining, 1896–1913

We investigate the wealth effects of takeovers in the mining industry of the German Ruhr district between 1896 and 1913. We employ event study methodology and use a new data set that covers stock prices of joint-stock mining companies and information on share prices of Gewerkschaften, an organisational form that was exclusively designed for German mining companies. Our empirical results show that takeovers enhanced shareholder value. The clear beneficiaries were the owners of the acquired companies, those of the acquirers hardly gained significantly. Collusion in the mining industry benefited the shareholders of small, poorly performing takeover targets.     

Value Creation in the Video Game Industry: Industry Economics,Consumer Benefits,and Research Opportunities

In the past twenty years, the video game industry has established itself as a significant contributor to the global entertainment economy. Compared to more established entertainment industries such as movies and music, limited scholarly research in marketing has addressed the processes that create value for companies and consumers in the context of video games which are now available on multiple devices (e.g., consoles, portables, mobile devices) and through multiple channels (e.g., retail and online). The authors therefore develop a conceptual framework of value creation through video games, highlight important findings from extant research in marketing and other disciplines, and apply the framework to derive future research opportunities.     

Verbraucherschutz als Teil der Marktordnung

In market orders, consumer protection is a necessary complement to competition policy in order to secure competition on the merits and the functioning of markets. Insights from behavioural economics show that disclosure obligations may not help boundedly rational consumers and that the standard paradigm of the “responsible and sovereign consumer” has to be modifi ed. “Nudging” and “debiasing” may be instrumental in preserving market freedom, while at the same time helping consumers to achieve desired results.
