Germany: ‘élite precaution’ alongside continued public opposition

Germany is the EU member state with the most difficult situation (besides Austria) for marketing genetically modified (GM) crops and food. At the same time, it shows the least administrative effort to respond to the reasons for this situation – public suspicion and protest. Regulators advocate specific precaution-related measures, including marketstage monitoring; these measures, however, do not relate to the primary demands of critics and opponents. The administration’s claim to prioritize scientific evidence over politics constructs the administration and the public as two separate worlds without real mediation. This conflicts with the ever-growing demands for public participation. Participation in a broader sense, however, is not dependent on formal opportunities. In this conflict, NGOs bring up issues of democracy, transparency and precaution through public mobilization. This strategy results in an anticipated consumer boycott and thereby a commercial blockage of GM products. These dynamics can be analysed as ‘reflexive modernization’, which implies greater public aversion to externally imposed risks. The politico-administrative system responds with a legalistic–scientistic approach in order to increase safety but without participatory measures to overcome predictive uncertainty and value conflicts. Environmental and consumer protest has led the technology providers to revise their political strategies in the biotechnology conflict. Thus, in Germany reflexive modernization takes place without reflexive politics.     

Country-level Accounting Enforcement and IPO Underpricing

Using a sample of up to 2,503 initial public offerings (IPOs) in 32 countries from 2011–2017, we predict and find that higher levels of country-level accounting enforcement are associated with lower levels of IPO underpricing. IPOs in countries with a relatively low accounting enforcement score (second quintile) exhibit a mean underpricing of 19%, whereas the mean underpricing amounts to just 9% in countries with a relatively high score (fourth quintile). The results remain qualitatively the same when we employ a multi-level model or a difference-in-difference design. In countries that substantially strengthened their accounting enforcement in the 2003–2009 period, the level of IPO underpricing decreased significantly. We show that accounting enforcement matters for the cost of going public.     

Beyond Dutch disease

How does the deterioration of rule of law in Russia in recent years affect its ability to move away from an export pattern dominated by natural resources? We investigate this question using three datasets for Russia's bilateral trade relations for goods, services and investment at disaggregated level with its partner countries over the world. Our empirical analysis shows that the deterioration of the rule of law in Russia since 2003 has affected the long‐run trade performance of Russia in sophisticated and technology‐intensive manufactured goods, as well as its inward investments with advanced economies. It is precisely this type of trade that Russia should nurture to diversify away from hydrocarbons export dependence. Our statistical analysis also shows that Russia remains to a large extent an outlier within the multilateral trading system. It exports disproportionately less to partner countries which are or had become members of the WTO over our period of analysis. Russia's trade appears to have been negatively affected by the accession of these countries to the WTO. Russia itself finally acceded to the WTO in July 2012 amidst signs of a modest improvement of its rule‐of‐law indicators.     

Determinants of exchange-rate regimes for currencies of developing countries: Some preliminary results

The breakdown of the Bretton Woods system gave the LDCs an opportunity to move away from exchange-rate regimes based on pegging to a single currency. Relatively few chose to do so, thus providing some evidence that, from their point of view, the recognized advantages of more flexible exchange-rate arrangements are more than outweighed by the recognized drawbacks.The aim of this article is to set up a suitable econometric model and use it for a preliminary assessment of the quantitative significance of various factors affecting the choice of exchange-rate regimes by the LDCs.     

Saving-based asset-pricing

This paper explores the implications of a novel class of preferences for the behavior of asset prices. Following a suggestion by Marshall (1920), we entertain the possibility that people derive utility not only from consumption, but also from the very act of saving. These “saving-based” preferences are related to models of habit formation and the spirit of capitalism, but incorporate the feature that people have anticipatory habits because they care about the future accumulation of wealth. We derive the Euler equations for these preferences and estimate them with GMM. Our estimates suggest that the preference for saving is economically significant.     

Fiscal federalism in monetary unions: hypothetical fiscal transfers within the Euro-zone

Net fiscal transfers are commonly seen as a possible means to ensure the well-functioning of a currency area. We show that US net fiscal transfers, measured as the difference between gross federal revenues and federal expenditures per state, are enormous. Moreover, we run panel regressions that suggest their dependence on relative GDP and relative GDP growth during crisis periods, evidence of net fiscal transfers from relatively rich to relatively poor states (redistributive effect) and to states with an underperforming economic development (stabilization effect). The Euro-zone (EZ) lacks a system of fiscal federalism, which raises the question of whether it should be established in the medium- and long-run. If so, which should be the magnitude of net fiscal transfers? We calculate these transfers hypothetically for 1999–2010, using a relative volume comparable to the one in the USA.
