Active and Forced Choice for Overcoming Status Quo Bias: A Field Experiment on the Adoption of “No junk mail” Stickers in Berlin,Germany

Consumers around the world are burdened by large amounts of unaddressed junk mail. Attaching “No junk mail” stickers to mailboxes offers a simple solution for protecting against unwanted ads. Presumably, the use of such stickers can be increased if consumers deliberately decide either for or against receiving junk mail. This conjecture of status quo bias was tested in a field experiment run with more than 900 households in Berlin, Germany. In one treatment, stickers were put into mailboxes, facilitating active choice. In a second treatment, stickers were attached halfway onto the outsides of mailboxes, forcing consumers to either remove or fully attach them. It was found that roughly a fifth of the sample attached a sticker after treatment. With uptake of more than 21, as compared to 16%, the forced choice was more effective than the active choice treatment. The findings highlight the importance of green nudges and defaults for promoting pro-environmental behaviour. Implications for landlords of the presented interventions are discussed. The field of social norms is identified as a promising area for extending the scope of the present study.     

Hedging costs and joint determinants of premiums and spreads in structured financial products

Evaluating more than 317,000 discount certificates in the German secondary market, we find that premiums and spreads are endogenous and negatively related but depend on different key determinants. The fundamental determinants of the premiums are mainly profit-related, that is, dividends of the underlying, issuers’ credit risk, lifecycle effect, and competition, whereas hedging costs are less important. However, initial hedging costs (IHC) are priced into the premium in the case of large inventory changes. The spread is mostly determined by hedging costs and risk components, such as IHCs, rebalancing costs, volatility, scalper risk, and overnight gap risk—but also by dividends.     

A New Regulatory Paradigm for the Digital Sector in Europe

The new regulatory framework in the digital sector in Europe is likely to fall short of expectations. A fragmented digital market with insuffi cient incentives for investment is the probable outcome. European regulators should abandon their approach in favour of a new and more flexible set of ideas discussed in this paper.

US trade policy in an unbalanced world economy

Both the national as well as the international debate on US trade policy are overshadowed, and strongly influenced, by the large external inbalances of major trading nations. What do these disequilibria mean for US trade policy? Moreover, is the USA losing comparative advantage in agriculture and high-technology manufacturing? Do industrial policies in other countries distort American trade?     

European Transport Policy in a Broader Perspective

On 12 July 2007 the European Parliament passed, with an overwhelming majority, a resolution on the Communication from the Commission to the Council and the European Parliament of 22 June 2006 entitled “Keep Europe moving – Sustainable mobility for our continent – Mid-term review of the European Commission's 2001 Transport White Paper”.1 This article outlines the main positions of the European Parliament in relation to the focal points of the Commission's position concerning present and future European transport policy.     

National and international developments in technology

Declining R&;D intensities at the national level coincide with growing international technological links. In this context a number of questions arise: Do companies research in the same field of technology abroad as they do at home? Are the fields of technology in which R&;D is concentrated within a country those in which it has a comparative advantage? What drives the process of the internationalisation of technology? What are the implications for host countries and home countries? What are the implications for policy on a national and an international level?
