An overnational cereal circuit for developing locally adapted organic seeds of wheat

On several locations in Germany and Switzerland, new and local varieties of winter wheat were compared to the variety "Bussard" in trial plots with 2-4 replications. Among other parameters, baking quality and gluten content were analised and discussed

National technology policies and international friction: Theory, evidence, and policy options

Economic theory and empirical evidence suggest that governments might usefully intervene in high-technology competition in two ways: First, they could act as a neutral agent that creates the necessary credibility, commitment and mutual trust among private companies so as to facilitate cooperation in high-risk, high-volume R&D. Second, if — in view of the externalities involved — an element of subsidization is to be added, this could be done in a nondiscriminatory fashion. A favourable tax treatment of R&D expenditures may be the most appropriate tool to achieve this task. In practice, governments do engage in targeted industrial and technology policies, whether justified on economic grounds or not. As a consequence, the string of trade conflicts in hightech industries that began in the 1980s is unlikely to end in the near future, unless substantial reforms are undertaken in some crucial areas of the international trade order. Above all, appropriate reform steps should be made with a view to the regulations on (i) subsidies, (ii) structural impediments, and (iii) dumping and anti-dumping. To mitigate the frictions that arise from a subsidization of domestic firms, a new set of rules should be established. The rules should provide that all plans to grant or to alter existing subsidies are to be notified to and approved by the WTO. Moreover, all subsidies should be ranked according to their potential distortional effects on competition and trade. For each category, quantitative limits that constrain the provision of subsidies to a certain fraction of the subsidy base should be set. To facilitate further liberalization steps, a country should be allowed to exceed these limits, if a national subsidy program offers an open access to firms located in third markets. Besides restrictive business practices of private firms, government regulations and technical standards are the most important structural impediments to trade. Existing GATT Articles already offer a multilateral route to conflict resolution in cases of structural impediments. However, this route has not been used by complainants up to now. The so-called "non-violation" clause of Article 23 GATT provides access to a multilateral dispute settlement even if the defending country has not explicitly violated GATT rules. This route should be tested and, if necessary, improved. To reduce the potential for a protectionist abuse of existing anti-dumping regulations, explicit reference to the state of competition in the relevant exporting and importing country markets should be made in anti-dumping investigations. To meet specific anti-trust concerns in hightech competition — notably with respect to network externalities, systems leverage, standardization, and innovation cartels — one might consider adopting the Draft International Antitrust Code (DIAC) that has recently been proposed by an international group of legal experts. --

Evolutionary diversity optimization using multi-objective indicators

Evolutionary diversity optimization aims to compute a set of solutions that are diverse in the search space or instance feature space, and where all solutions meet a given quality criterion. With this paper, we bridge the areas of evolutionary diversity optimization and evolutionary multi-objective optimization. We show how popular indicators frequently used in the area of multi-objective optimization can be used for evolutionary diversity optimization. Our experimental investigations for evolving diverse sets of TSP instances and images according to various features show that two of the most prominent multi-objective indicators, namely the hypervolume indicator and the inverted generational distance, provide excellent results in terms of visualization and various diversity indicators.Aneta Neumann, Wanru Gao, Markus Wagner, Frank Neuman

Assessing the impact of health care expenditures on mortality using cross-country data

A significant body of literature has examined the impact of public health expenditure on mortality, using a global cross-section or panel of country-level data. However, while a number of studies do confirm such a relationship, the magnitude of the impact varies considerably between studies, and several studies show statistically insignificant effects. In this paper we re-examine the literature that identifies this effect using cross-country data. Our analysis builds on the two instrumental variables (IV) approaches embodied by key publications in the field – Bokhari et al. (2007) and Moreno-Serra and Smith (2015). Using exactly the same data and econometric specifications as the published studies, we start by successfully replicating their findings. However, further analyses using updated data and ‘streamlined’ econometric specifications, plus statistical data imputation and extensive robustness checks, reveal highly sensitive results. In particular, the relevance of the IVs is seriously compromised in the updated data, leading to imprecise estimations of the relationship. While our results should not be taken to imply that there is no true mortality-reducing impact of public health care expenditures on mortality, the findings do call for further methodological work, for instance in terms of identifying more suitable IVs or by applying other estimation strategies, in an effort to derive more robust estimates of the marginal productivity of public health care funding
