Long‐term care policy with lazy rotten kids

This paper studies the determination of informal long‐term care (LTC) provided by children in a scenario which is somewhere in between perfect altruism and selfish exchanges. Parents are altruistic but children are purely selfish, and neither side can make credible commitments. The model is based on Becker's “rotten kid” specification except that it explicitly accounts for the sequence of decisions. In Becker's world, with a single good efficiency is achieved. We show that when family aid is introduced the outcome is likely to be inefficient. Still, the rotten kid mechanism is at work and ensures that a positive level of LTC is provided as long as the bequest motive is operative. We identify the inefficiencies by comparing the laissez‐faire (subgame perfect) equilibrium to the first‐best allocation. We first assume that families are identical ex ante and then consider the case where dynasties differ in wealth. We study how the provision of LTC can be improved by public policies. Interestingly, crowding out of private aid by public LTC is not a problem in this setting. With an operative bequest motive, public LTC will have no impact on private aid. More amazingly still, when the bequest motive is (initially) not operative, public insurance may even enhance the provision of informal aid.     

A comparative study of stakeholder risk perception and risk communication in Europe: a bovine spongiform encephalopathy case study

The ‘Transmissible Spongiform Encephalopathy (TSE) Roadmap’ was published by the European Commission on 15 July 2005. The TSE Roadmap proposes the relaxation of bovine spongiform encephalopathy (BSE) measures in the short, medium and long term. According to the Roadmap, any relaxation of BSE measures following the scientific assessment should be initiated by an open discussion with all stakeholders and supported by a strong communication strategy. This paper discusses the risk perception, risk communication and risk management of TSEs in Europe, exemplified by the TSE Roadmap. The main conclusion is that in general, BSE is no longer a ‘hot’ topic for stakeholders, but there are slight differences between countries with respect to specific measures. Another important conclusion is that the TSE Roadmap is a very effective tool for risk communication with stakeholders.     

Price Discrimination in Russian Wheat Exports: Evidence from Firm‐level Data

Russia emerged as an important wheat exporter in recent years raising the question of how this will affect international wheat markets. In particular developing countries – the main destination of Russian wheat exports – could be harmed by aggressive pricing behaviour. This article analyses the exertion of price discrimination by Russian wheat exporting firms based on Krugman's pricing‐to‐market hypothesis. We apply Knetter's panel model to a firm‐level dataset and find evidence for price‐discriminating behaviour by Russian firms in 25 out of 61 destination countries over the period 2002–2011.     

Did globalization drive convergence? Identifying cross-country growth regimes in the long run

This paper is the first to apply a finite mixture model to a sample of 64 nations to endogenously analyze the cross-country growth behavior over the period 1870–2003. Results show that growth patterns were segmented in two worldwide regimes, the one characterized by convergence in per capita income, and the other by divergence. Interestingly, when three historical epochs are distinctly analyzed, in order to investigate the empirical link between globalization and convergence, the dynamics which dominated over the whole period seem to have emerged only during the post-1950 years. In contrast, the First Global Wave was marked by persistent heterogeneities.     

Identification of future fields of standardisation: An explorative application of the Delphi methodology

This paper investigates the application of the Delphi methodology for the identification of future fields of standardisation complemented by a methodological extension by using various science and technology indicators. By the term standardisation, we broadly mean the process of developing and implementing technical standards within a standardisation body. Underlining the explorative nature of this paper, we describe the process of identifying future fields of standardisation.To provide a systematic forecasting view on complex science and technology fields, a combination of quantitative indicator-based analyses and qualitative in-depth Delphi surveys is choosen. Firstly, statistical analyses of suitable indicators are used to identify dynamic developments in such fields. Secondly, to identify detailed challenges for future standardisation, qualitative Delphi surveys are conducted. To collect and evaluate relevant issues the respective expert communities were included. They were identified by using information derived from the science and technology databases used.The paper concludes with the assessment of the chosen approach and give practical insights for its feasibility based on a review of the existing literature on the Delphi methodology. In addition, an outlook for further improvements and other possible fields of application is given.     

Taxation and consumption: evidence from a representative survey of the German population

Using a representative survey of the German population, this article studies self-reported individual consumption responses to a recent exogenous payroll tax reduction. About 55% of the respondents report that they spend the extra money, indicating considerable potential for tax changes to affect consumption and economic activity. Our analysis of the socio-demographic and economic covariates of consumption responses suggests, among other effects, that interest rates are related to consumption responses to tax changes, and that households with higher income have a higher propensity to consume.     

中国和国际林产品贸易对森林保护和人民生计的影响

分析了中国林产品进出口的总量、结构、变化、增长趋势及对相关国家和地区人民生计的影响,提出了作为进口国消费国、生产国和加工国应采取的措施。1997年到2005年间,中国林产品进口总量折合原木材积增长了两倍多,从0.40亿m3增长到1.34亿m3,进口额也翻了一番。2005年,俄罗斯、马来西亚、印尼、泰国、巴布新几内亚列中国总木质林产品进口前5名,进口额占71.6%;加拿大、印尼、俄罗斯、智利、美国列纸浆进口前5位,进口额占77.6%;美国、日本、香港、欧盟是中国林产品出口的主要目的地。中国迅速增长的林产品贸易对国际社会也有消极影响,导致不可持续采伐、非法采伐等问题,但中国只是全球产业链上的一环,来自美国、欧盟和日本的购买者和零售商也负有不可推卸的责任。中国应认清其在国际林产品贸易中的关键地位,加快其林业部门的改革步伐,推动本国的林产品生产和供给,实现可持续的林业发展。     

Transformationen im Journalismus

In commercial broadcasting, the entertaining features of journalism are already prevalent and expected to increase further. Beyond the aspect of entertainment, a far-reaching process of transformation in journalism can be identified, to be clearly recognized in several domains: With purposes shifting away from information and towards entertainment, journalism changes its organizational structures, its working routines as well as the roles and the qualifications of its workforce. Based on an empirical study carried out in northern Germany, the article describes the organization and work »programmes« in »format radios« and discusses the resulting changes in journalists’ qualifications. The findings have led to the conclusion that, because of the lack of organizational and working structures at private radio stations, journalists will have to meet all the demands of the complete production process, both with respect to hierarchies and functions (»Everyone does each and everything«). The more organization »programmes« lose their determining influence, the more coordinating activities will be needed. That is to say, organizational structures are being replaced by social processes. As a consequence, the ability to communicate, as one of the elements of journalistic qualification, is of growing importance.
