AbstractCommonly QTL detection in multi-parent population (MPPs) data measured in multiple environments (ME) is done by a single environment analysis on phenotypic values ‘averaged’ across environments. This method can be useful to detect QTLs with a consistent effect across environments but it does not allow to estimate environment-specific QTL (QTLxE) effects. Running separate single environment analyses is a possibility to measure QTLxE effects but those analyses do not model the genetic covariance due to the use of the same genotype in different environments. In this paper, we propose methods to analyze MPP-ME QTL experiments using simultaneously the data from several environments and modelling the genotypic covariances. Using data from the EU-NAM and the US-NAM populations, we show that these methods allow to estimate the QTLxE effects and that they give a more precise description of the trait genetic architecture than separate within environment analyses. The MPP-ME models we propose can also be extended to integrate environmental indices (e.g. temperature, precipitation, etc.) to understand better the mechanisms behind the QTLxE effects. Therefore, our methodology allows to exploit the full potential of MPP-ME data: to estimate QTL effect variations a) within the MPP between sub-populations due to different genetic backgrounds; and b) between environments.

This paper seeks to provide an overview of conflict mineral trade by analyzing it through an economic lens. Using data gathered from news sources, the memo first defines the term “conflict minerals” and identifies that the primary actors involved in the conflict mineral market are rebel militia groups and multinational corporations. The trade is mutually beneficial for these actors as it serves as the primary source of revenue for militia groups and allows multinational corporations to buy minerals at low costs. The memo also highlights the struggles legitimate Congolese miners face, as they face threats from militia groups and low market prices Also identified is Section 1502 of the Dodd Frank act, legislation which forces multinational corporations to list their mineral suppliers, thereby increasing supply chain transparency. While implemented with good intentions, it is extremely unsuccessful in stifling the conflict mineral trade as it lacks substantive regulatory measures. Furthermore, the EU and US plan to implement opposing conflict mineral trade policies — the EU looks to increase supply chain transparency while the US looks to repeal Section 1502 of Dodd Frank (an action which would decrease supply chain transparency). This paper believes that coordinated and homogenous action on the part of both federal governments and IGOs is necessary in order to concretely enforce restrictions on conflict mineral trade.

Using data from a large-scale survey of employees in Ireland, we estimate the extent to which people who have emigrated from Ireland and returned earn more relative to comparable people who have never lived abroad. In so doing, we test the hypothesis that migration can be part of a process of human capital formation. We find through OLS estimation that returners earn 7 per cent more than comparable stayers. We test for the presence of self-selection bias in this estimate but the tests suggest that the premium is related to returner status. The premium holds for both genders, is higher for people with postgraduate degrees and for people who migrated beyond the EU to the US, Canada, Australia and New Zealand. The results show how emigration can be positive for a source country when viewed in a longer-term context.

This article examines fundamental questions of monetary policy in the context of challenges to the national security of Russia in connection with the imposition of economic sanctions by the US and the EU. It is proved that the policy of the Russian monetary authorities, particularly the Central Bank, artificially limiting the money supply in the domestic market and pandering to the export of capital, compounds the effects of economic sanctions and plunges the economy into depression. The article presents practical advice on the transition from external to domestic sources of long-term credit with the simultaneous adoption of measures to prevent capital flight.

Agriculture Support

The article deals with the features of the Russian policy of agriculture support in comparison with the EU and the US policies. Comparative analysis is held considering the scales and levels of collective agriculture support, sources of supporting means, levels and mechanisms of support of agricultural production manufacturers, its consumers, agrarian infrastructure establishments, manufacturers and consumers of each of the principal types of agriculture production. The author makes an attempt to estimate the consequences of Russia’s accession to the World Trade Organization based on a hypothesis that this will result in unification of the manufacturers and consumers’ protection levels in Russia with the countries that have long been WTO members.

The EU is about to abolish the sugar – and the isoglucose – quota system in 2016/17. Isoglucose made from corn occupies about 50% of the US sweetener market while its market share in the EU caloric sweetener market is less than 5%. Against this background, this paper analyses the economics of isoglucose production in Europe in order to understand its competitiveness vis-à-vis sugar. Key results: (1) Isoglucose will become a rather competitive product. The EU sugar industry will have to give up about 40% of its current processing and profit margin in order to sell sugar at the same price as isoglucose will be traded; (2) Once industrial sugar users move to isoglucose, they will tend to be “hooked-in,” giving the sugar industry a strong incentive to defend its market share; and (3) Since only about 30% of the current sugar market is able to switch to isoglucose, the sugar industry has the option to practice a mixed calculation. In an extreme scenario, the industry may even opt to cross-subsidize sales. Therefore it’s not clear whether investors in isoglucose will be able to gain a major market share in Europe.

The article is devoted to problems in relations between the EU and Russia. Multiple methods are considered that are aimed at solving the problem of multilateralism in current conditions. The author selected and studied specific documents on essential aspects that are devoted to this topic. Studying the arising problems requires careful consideration since, in the modern world, cooperation between global actors such as the EU and Russia cannot be ignored. Despite all the challenges faced by the parties in their fields, all difficulties are conquerable, and the article provides specific methods for its solving. The article discusses some aspects and problems that require particular attention from specialists in this field. The author concludes that strong US–EU coalition could seem more coherent with history and with the traditional East–West divide. However, the recent evolution of the US attitude towards international relations weakens the probability of such coalition and its perceived payoffs. A more or less defensive Russia–China coalition has been tried with limited results; moreover, if it were possible and probable, the two western players would change their strategy to prevent it or to contain its depth. In fact, we live in a world where many talks of a serious possibility of G2 governance, a peculiar type of coalition where the US and China keep hostile and nationalistic attitudes but join forces to set the global stage in their favor, pursuing a qualitatively limited but quantitatively rich payoff. In such world, as a counterpart of this payoff, both the divided Europe and the economically much smaller Russia would lose power and suffer several kinds of economic disadvantages. Therefore, Greater Europe would be good for Russia and for the EU as well.

Secrecy and informality rather than transparency traditionally reign trade negotiations at the bilateral, regional, and multilateral levels. Yet, transparency ranks among the most basic desiderata in the grammar of global governance and has been regarded as positively related to legitimacy. In the EU’s case, transparent trade diplomacy is quintessential for constitutional—but also for broader political—reasons. First, even if trade matters fall within the EU’s exclusive competence, the EU executive is bound by the Treaty on the Functioning of the European Union (TFEU) to inform the European Parliament, the EU co-legislator, in regular intervals. Second, transparency at an early stage is important to address public reluctance, suspicion, or even opposition regarding a particular trade deal. This chapter chronicles the quest for and turning moments relating to transparency during the EU trade negotiations with Canada (CETA); the US (TTIP), and various WTO members on services (TiSA).
