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.     

MEASURING RICHNESS AND POVERTY: A MICRO DATA APPLICATION TO EUROPE AND GERMANY

In this paper, we define a new class of richness measures. In contrast to the often used headcount, these new measures are sensitive to changes in rich individuals' incomes and, therefore, allow for a more sophisticated analysis of richness. We demonstrate the application of these new measures in analyzing the development of poverty and richness over time in Germany. Moreover, we compare Germany to many other European countries and investigate the impact of tax reforms on poverty and richness. Using these examples, we show the importance of taking the intensity of changes into account and not only the number of people beyond a given richness line (headcount). We propose to use the new measures in addition to the headcount index for a more comprehensive analysis of richness.     

Basel II and bank lending to emerging markets: Evidence from the German banking sector

This paper investigates whether the new Basel Accord will induce a change in bank lending to emerging markets using a comprehensive new data set on German banks’ foreign exposure. We test two interlinked hypotheses on the conditions under which the change in the regulatory capital would leave lending flows unaffected. This would be the case if (i) the new regulatory capital requirement remains below the economic capital and (ii) banks’ economic capital to emerging markets already adequately reflects risk. On both accounts the evidence indicates that the new Basel Accord should have a limited effect on lending to emerging markets.     

The Environmental Impact of European Farming: How Legitimate Are Agri-Environmental Payments?

Offering agri-environmental payments to address the various positive and negative environmental nonmarket effects of European Union agriculture might be an efficient way of dealing with market imperfections. However, the complex interaction between farming practices and agri-environmental effects makes it difficult to assess what level of payments is justified under World Trade Organization's Green Box provisions. In reviewing the literature on positive and negative externalities of European farming on the environment, we find evidence to suggest that paying for agri-environmental improvements may be appropriate under the Green Box provisions, even if the payments have a positive production effect.     

The influence of taxes on migration: evidence from Switzerland

Empirical studies on the impact of taxation on migration havebeen limited by a lack of comparable data in an internationalcontext and a lack of variation in tax burdens within countries.A notable exception to the latter is Switzerland. Prior empiricalstudies on tax competition in Switzerland have had to rely onaggregated data. In general, these studies have been supportiveof the notion of tax competition, i.e., high earners tend torelocate to low-tax regions. The authors use an alternativepanel approach based on micro-data from the first three wavesof the newly established Swiss Household Panel. Despite activecommunity tax policies aimed at attracting new residents anda significant increase in tax-burden dispersion among communitiesin the past decade, no tax-induced migration is observed. Migrationdecisions are found to be strongly influenced by accommodation-relatedfactors that point to important housing-market effects.     

Is a flat tax reform feasible in a grown-up democracy of Western Europe? A simulation study for Germany

The success of the flat rate income tax in eastern Europe suggests that this concept could also be a model for countries of western Europe. The present paper uses a simulation model to analyze the effects of revenue neutral flat rate tax reforms on equity and efficiency for the case of Germany. We find that a flat rate tax with a low tax rate and a low basic allowance yields positive static welfare effects amounting to approximately 1.8% of income tax revenue but increases income inequality. The increase in income inequality can be avoided by combining a higher tax rate with a higher basic allowance. But in this case, the efficiency gains vanish. We conclude that due to their limited efficiency effects and their problematic distributional impact, flat tax reforms are unlikely to spill over to the grown-up democracies of western Europe.
