Individual risk attitudes and the composition of financial portfolios: Evidence from German household portfolios

This paper explores the relationship between the self-declared risk aversion of private investors and their propensity to hold incomplete portfolios of financial assets. The analysis is based on household survey data from the German Socioeconomic Panel (SOEP) that provides a reliable measure of individual attitudes toward financial risk. Our findings suggest that more risk averse households tend to hold incomplete portfolios consisting mainly of a few risk-free assets. We also find that the propensity to acquire additional assets is highly dependent on whether liquidity and safety needs are met.     

Do individual investors’ stock recommendations in online communities contain investment value?

This paper investigates the investment value of individual investors’ stock recommendations within online communities. We find that aggregated recommendations contain no explicit investment value and that following these recommendations may have a negative impact on investment performance. Our results suggest that recommendations are mostly based on simple heuristics and concentrate on a small number of stocks. When restricting the set of recommendations to those made by the most experienced or successful recommenders, results marginally improve but still preclude profitable investment strategies. Experienced and successful recommenders seem more likely to avoid the most expensive pitfalls rather than actually exhibit superior investment performance.     

Intellectual property marketplaces and how they work: Evidence from German pharmaceutical firms

This article examines a sample of German pharmaceutical firms to highlight the strategic reasons why firms participate in various intellectual property (IP) marketplaces, both proprietary (patents and copyrights) and non-proprietary (open source and non-patented technology). The obstacles that prevent these marketplaces from functioning efficiently are also investigated. The analysis suggests that IP policy must embrace all IP forms and must recognise that IP marketplaces do not work “automatically” but suffer many institutional failures.     

The impact of broadband on jobs and the German economy

This study calculates the impact of investment in broadband technology on German employment and economic output. Two sequential investment scenarios are analysed: the first one reflects the government’s National Broadband Strategy that extends through 2014, and the second covers the ultra-broadband evolution from 2015 to 2020. The authors conclude that the required investment of close to 36 billion euros is justifi ed by the substantial benefi ts that would be generated in terms of both additional jobs and GDP growth.     

Reconsidering the Shareholder's Role in Corporate Reorganisations under Insolvency Law

A corporate reorganisation under insolvency law is commonly achieved by virtue of a reorganisation plan that provides for the distribution and sacrifice of value among all stakeholders in an insolvent company. Although the creditors' right to vote on such plans and to participate in the wealth distribution according to such plans is universally accepted, the role of old equity in a corporate reorganisation remains a topic that jurisdictions all over the world define very differently. This article first explores possible approaches to shareholders' treatment under insolvency law and supports their inclusion in insolvency proceedings that pursue corporate reorganisations. It then argues that equity interest should not solely be treated according to its economic value and consequently that no absolute priority rule should be applied against them as such treatment would ignore the fundamental difference between liquidation and reorganisation. Finally, it proposes a new cram‐down rule for a class of equity holders. Copyright © 2013 INSOL International and John Wiley & Sons, Ltd.     

Crowding Out Informal Care? Evidence from a Field Experiment in Germany*

This article evaluates the effects of a consumer‐directed home care programme (Personal Budgets) compared with the standard home care programmes of the German long‐term care insurance (LTCI). The evaluation makes use of a random assignment into a treatment group receiving personal budgets and a control group receiving either in‐kind benefits (agency care) or cash payments. Compared with agency care, personal budgets extend the support by independent providers, but leave health outcomes unchanged. Compared with cash payments, personal budgets tend to improve health outcomes, but double LTCI spending due to a strong crowding out of informal care by formal care.     

Product Safety Provision and Consumers' Information

Economic mechanisms related to the provision of product safety are explored, with particular attention paid to the structure of consumers' information. The case of perfect information, of experience goods (for which consumers detect product safety after consumption) and of credence goods (where consumers cannot link a disease to a particular product consumed in the past) are explored. Imperfect competition is assumed in the supply sector. In the case of both perfect information and experience goods, market equilibrium is characterised by a less-than-socially optimal provision of safety, when the safety effort is costly. With credence goods, imperfect information leads to the absence of safety effort and to a market closure. Different types of public regulation aiming at increasing consumer protection and circumventing market failures are explored. Particular attention is paid to minimum safety standards, labels and liability enforcement. The relative efficiency of these instruments depends on the information structure. In the cases of perfect information and experience goods, a minimum safety standard can be an efficient instrument. Regulation is necessary but not sufficient to avoid market failure in the case of credence goods.     

Should Welfare Administration be Centralized or Decentralized? Evidence from a Policy Experiment

The 2005 reform of the German welfare system introduced two competing organizational models for welfare administration. In most districts, a centralized organization was established where local welfare agencies are bound to central directives. At the same time, 69 districts were allowed to opt for a decentralized organization. We evaluate the relative success of both types in terms of integrating welfare recipients into employment. Compared to centralized organization, decentralized organization has a negative effect on employment chances of males. For women, no significant effect is found. These findings are robust to the inclusion of aspects of internal organization common to both types of agencies.
