The role of Preferential Trade Agreements (PTAs) in facilitating global production networks

This paper examines the effects of preferential trade agreements (PTAs) in facilitating international trade flows connecting production networks. We consider over 250 PTAs with trade flows distinguished into parts and components and final goods for the period 1979-2008. The gravity equation estimates suggest that the concurrent year effects of PTA formation on trade in parts and components are unseen, whereas PTAs have positive and pervasive effects on both types of trade flows 6 and 9 years after the PTA formation.

Five growth strategies for Myanmar : re-engagement with the global economy

After decades of isolation, Myanmar is now actively re-engaging with the global economy. For successful re-engagement, Myanmar needs to implement comprehensive economic reforms based on a shared vision for long-term economic development that is characterized by human-centered, high, sustainable, pro-poor, inclusive, and balanced economic growth. In this paper, we propose five growth strategies: "Agriculture Plus Plus," an export-oriented strategy, a foreign direct investment-driven strategy, a two-polar growth strategy, and a strategy to develop domestic economic corridors. These strategies are used as guides to translate these development agendas into a set of implementable policies, programs, and projects.

Platforms and firm capabilities : a study of emerging global value chains

This paper discusses globalization’s impact on production and distribution systems in emerging economies. On one hand, globalization has resulted in an increasing number of multinational corporations to adopt a platform strategy for their customers in emerging markets. On the other hand, developing countries have witnessed the integration of an increasing number of traditional marketplaces into a powerful distribution system, characterized as a specialized market system. Consequently, an unique industrial organization has developed in emerging economies, regarded as emerging global value chains (EGVCs). They comprise a large number of small firms together with a small number of large platform providers and display the "market" type general governance patterns. Firms in EGVCs are more likely to realize functional upgrading and grow into strong lead firms.

On the Use of Matrix-Free Shift-Invert Strategies For Global Flow Instability Analysis

A novel time-stepping shift-invert algorithm for linear stability analysis of laminar flows in complex geometries is presented. This method, based on a Krylov subspace iteration, enables the solution of complex non-symmetric eigenvalue problems in a matrix-free framework. Validations and comparisons to the classical exponential method have been performed in three different cases: (i) stenotic flow, (ii) backward-facing step and (iii) lid-driven swirling flow. Results show that this new approach speeds up the required Krylov subspace iterations and has the capability of converging to specific parts of the global spectrum. It is shown that, although the exponential method remains the method of choice if leading eigenvalues are sought, the performance of the present method could be dramatically improved with the use of a preconditioner. In addition, as opposed to other methods, this strategy can be directly applied to any time-stepper, regardless of the temporal or spatial discretization of the latter.

Global instability analysis and control of three-dimensional long open cavity flow

The three-dimensional wall-bounded open cavity may be considered as a simplified geometry found in industrial applications such as leading gear or slotted flats on the airplane. Understanding the three-dimensional complex flow structure that surrounds this particular geometry is therefore of major industrial interest. At the light of the remarkable former investigations in this kind of flows, enough evidences suggest that the lateral walls have a great influence on the flow features and hence on their instability modes. Nevertheless, even though there is a large body of literature on cavity flows, most of them are based on the assumption that the flow is two-dimensional and spanwise-periodic. The flow over realistic open cavity should be considered. This thesis presents an investigation of three-dimensional wall-bounded open cavity with geometric ratio 6:2:1. To this aim, three-dimensional Direct Numerical Simulation (DNS) and global linear instability have been performed. Linear instability analysis reveals that the onset of the first instability in this open cavity is around Recr 1080. The three-dimensional shear layer mode with a complex structure is shown to be the most unstable mode. I t is noteworthy that the flow pattern of this high-frequency shear layer mode is similar to the observed unstable oscillations in supercritical unstable case. DNS of the cavity flow carried out at different Reynolds number from steady state until a nonlinear saturated state is obtained. The comparison of time histories of kinetic energy presents a clearly dominant energetic mode which shifts between low-frequency and highfrequency oscillation. A complete flow patterns from subcritical cases to supercritical case has been put in evidence. The flow structure at the supercritical case Re=1100 resembles typical wake-shedding instability oscillations with a lateral motion existed in the subcritical cases. Also, This flow pattern is similar to the observations in experiments. In order to validate the linear instability analysis results, the topology of the composite flow fields reconstructed by linear superposition of a three-dimensional base flow and its leading three-dimensional global eigenmodes has been studied. The instantaneous wall streamlines of those composited flows display distinguish influence region of each eigenmode. Attention has been focused on the leading high-frequency shear layer mode; the composite flow fields have been fully recognized with respect to the downstream wave shedding. The three-dimensional shear layer mode is shown to give rise to a typical wake-shedding instability with a lateral motions occurring downstream which is in good agreement with the experiment results. Moreover, the spanwise-periodic, open cavity with the same length to depth ratio has been also studied. The most unstable linear mode is different from the real three-dimensional cavity flow, because of the existence of the side walls. Structure sensitivity of the unstable global mode is analyzed in the flow control context. The adjoint-based sensitivity analysis has been employed to localized the receptivity region, where the flow is more sensible to momentum forcing and mass injection. Because of the non-normality of the linearized Navier-Stokes equations, the direct and adjoint field has a large spatial separation. The strongest sensitivity region is locate in the upstream lip of the three-dimensional cavity. This numerical finding is in agreement with experimental observations. Finally, a prototype of passive flow control strategy is applied.

Aurintricarboxylic acid prevents GLUR2 mRNA down-regulation and delayed neurodegeneration in hippocampal CA1 neurons of gerbil after global ischemia

Aurintricarboxylic acid (ATA), an inhibitor of endonuclease activity and other protein–nucleic acid interactions, blocks apoptosis in several cell types and prevents delayed death of hippocampal pyramidal CA1 neurons induced by transient global ischemia. Global ischemia in rats and gerbils induces down-regulation of GluR2 mRNA and increased α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA)-induced Ca2+ influx in CA1 before neurodegeneration. This result and neuroprotection by antagonists of AMPA receptors suggests that formation of AMPA receptors lacking GluR2, and therefore Ca2+ permeable, leads to excessive Ca2+ influx in response to endogenous glutamate; the resulting delayed neuronal death in CA1 exhibits many characteristics of apoptosis. In this study, we examined the effects of ATA on expression of mRNAs encoding glutamate receptor subunits in gerbil hippocampus after global ischemia. Administration of ATA by injection into the right cerebral ventricle 1 h before (but not 6 h after) bilateral carotid occlusion prevented the ischemia-induced decrease in GluR2 mRNA expression and the delayed neurodegeneration. These findings suggest that ATA is neuroprotective in ischemia by blocking the transcriptional changes leading to down-regulation of GluR2, rather than by simply blocking endonucleases, which presumably act later after Ca2+ influx initiates apoptosis. Maintaining formation of Ca2+ impermeable, GluR2 containing AMPA receptors could prevent delayed death of CA1 neurons after transient global ischemia, and block of GluR2 down-regulation may provide a further strategy for neuroprotection.

Modeling the impact of global tuberculosis control strategies

An epidemiological model of tuberculosis has been developed and applied to five regions of the world. Globally, 6.7 million new cases of tuberculosis and 2.4 million deaths from tuberculosis are estimated for 1998. Based on current trends in uptake of the World Health Organization’s strategy of directly observed treatment, short-course, we expect a total of 225 million new cases and 79 million deaths from tuberculosis between 1998 and 2030. Active case-finding by using mass miniature radiography could save 23 million lives over this period. A single contact treatment for tuberculosis could avert 24 million cases and 11 million deaths; combined with active screening, it could reduce mortality by nearly 40%. A new vaccine with 50% efficacy could lower incidence by 36 million cases and mortality by 9 million deaths. Support for major extensions to global tuberculosis control strategies will occur only if the size of the problem and the potential for action are recognized more widely.

The Europe 2020 Strategy: Can it maintain the EU’s competitiveness in the world? CEPS Paperbacks. September 2012

Launched in March 2010 by the European Commission, the Europe 2020 strategy aims at achieving “smart, sustainable and inclusive” growth. This growth is intended to be driven by three sets of engines: knowledge and innovation, a greener and more efficient use of resources and higher employment combined with social and territorial cohesion. This CEPS report takes an in-depth look at the Europe 2020 strategy and the goals it sets for the EU, with the aim of shedding light on the question of whether the strategy will succeed in fostering the global competitiveness of the European Union. While finding that the Europe 2020 strategy identifies the right key indicators for its targets, the authors advise that it should be revised in several important respects and conclude with relevant policy steps to foster the future capability of European economies and their prosperity.

The European Union Maritime Security Strategy: sailing uncharted waters? EPC Commentary, 26 June 2014

On 24 June 2014 the General Affairs Council of the European Union approved the “European Union Maritime Security Strategy��� (EUMSS), following the mandate by EU Heads of State or Government in their ‘Defence Summit’ last December and building on the Joint Communication “For An Open and Secure Global Maritime Domain” by the European Commission and the High Representative for Foreign Affairs and Security Policy in early March. These documents come at a time of considerable transformations in ‘the world’s last global common’: the sea.

The European Union and global security: is the EU becoming the indispensable partner? EU Centre Singapore Background Brief No. 11, April 2014

The European Union has developed new capacity as a security actor in third countries, in particular in the area of crisis management. Over the past two decades the EU has deployed numerous missions, both of a civilian and military nature. Moreover the EU has defined its ability to intervene all along the ‘crisis cycle’, (from prevention to mediation, from peace-keeping to post-conflict reconstruction) and using all tools at its disposal (taking a ‘comprehensive approach’). However the EU is still not perceived as a major security provider globally and interventions remain limited to some geographic areas, mostly in its neighbourhood and Africa, with just a few examples further afield. The EU also tends to avoid taking direct action and seems to prefer partnership arrangements with other players. How can we explain the growing activism and number of EU’s intervention with the low impact and lack of visibility? Can we expect the EU to become more active in the future, taking on more responsibility and leading roles in addressing conflict situations? This paper will argue that the main reason for the EU’s hesitant role in crisis management is to be found in the weak decision-making provisions for EU’s security interventions, as one of the few policy areas still subject to consensus amongst 28 European Union Member States. Lack of a clearer delegation of competence or stronger coordination structures is closely linked to low legitimacy for the EU to take more robust action as a security actor. In order to overcome this legitimacy problem, and in order to facilitate consensus amongst Member States, the EU thus privileges partnership arrangements with other actors who can provide legitimacy and know-how, such as the UN or the African Union. As there is no political desire in the EU for tighter decision-making in this area, we can expect that the EU will continue to play a supporting rather than leading role in crisis management, becoming the partner of choice as it deepens its experience. However this does not mean that the EU is playing just a secondary role in the wider area of security, in particular when looking at nontraditional security. Looking at the role of the EU in Asia, where the EU has deployed just two missions, this paper will offer a broader assessment of the EU as a partner in the area of security taking into account different types of actions. The paper will argue that in order to strengthen cooperation with Asian partners in the area of crisis management, the EU will need to define better what it is able to offer, present its actions as part of an overall strategy rather than ad-hoc and piecemeal, and enter into partnership arrangements with different players in the region.

Renewables: The great uncertainty of the EU energy strategy. Egmont Paper No. 71, November 2014

Summary. For more than two decades, the development of renewable energy sources (RES) has been an important aim of EU energy policy. It accelerated with the adoption of a 1997 White Paper and the setting a decade later of a 20% renewable energy target, to be reached by 2020. The EU counts on renewable energy for multiple purposes: to diversify its energy supply; to increase its security of supply; and to create new industries, jobs, economic growth and export opportunities, while at the same time reducing greenhouse gas (GHG) emissions. Many expectations rest on its development. Fossil fuels have been critical to the development of industrial nations, including EU Member States, which are now deeply reliant upon coal, oil and gas for nearly every aspect of their existence. Faced with some hard truths, however, the Member States have begun to shelve fossil fuel. These hard truths are as follows: firstly, fossil fuels are a finite resource, sometimes difficult to extract. This means that, at some point, fossil fuels are going to be more difficult to access in Europe or too expensive to use.1 The problem is that you cannot just stop using fossil fuels when they become too expensive; the existing infrastructure is profoundly reliant on fossil fuels. It is thus almost normal that a fierce resistance to change exists. Secondly, fossil fuels contribute to climate change. They emit GHG, which contribute greatly to climate change. As a consequence, their use needs to be drastically reduced. Thirdly, Member States are currently suffering a decline in their own fossil fuel production. This increases their dependence on increasingly costly fossil fuel imports from increasingly unstable countries. This problem is compounded by global developments: the growing share of emerging economies in global energy demand (in particular China and India but also the Middle East) and the development of unconventional oil and gas production in the United States. All these elements endanger the competitiveness of Member States’ economies and their security of supply. Therefore, new indigenous sources of energy and a diversification of energy suppliers and routes to convey energy need to be found. To solve all these challenges, in 2008 the EU put in place a strategy based on three objectives: sustainability (reduction of GHG), competitiveness and security of supply. The adoption of a renewable energy policy was considered essential for reaching these three strategic objectives. The adoption of the 20% renewable energy target has undeniably had a positive effect in the EU on the growth in renewables, with the result that renewable energy sources are steadily increasing their presence in the EU energy mix. They are now, it can be said, an integral part of the EU energy system. However, the necessity of reaching this 20% renewable energy target in 2020, combined with other circumstances, has also engendered in many Member States a certain number of difficulties, creating uncertainties for investors and postponing benefits for consumers. The electricity sector is the clearest example of this downside. Subsidies have become extremely abundant and vary from one Member State to another, compromising both fair competition and single market. Networks encountered many difficulties to develop and adapt. With technological progress these subsidies have also become quite excessive. The growing impact of renewable electricity fluctuations has made some traditional power plants unprofitable and created disincentives for new investments. The EU does clearly need to reassess its strategy. If it repeats the 2008 measures it will risk to provoke increased instability and costs.

Gazprom’s evolving strategy in a new commercial and political context: how should the EU react? EPC Policy Brief, 27 April 2015

After years of unchallenged commercial domination of a sizeable portion of the EU's gas market, Gazprom is confronted with a statement of objections issued on 22 April by the EU Commission for abusing its dominant market position. The company was already prevented from going ahead with its South Stream project aimed at consolidating Gazprom's grip on Southeast Europe's markets by bypassing Ukraine – due to alleged non-compliance of intergovernmental agreements with the EU regulatory framework. Furthermore, it walked away from negotiations that could have allowed it to access more than 50% of the OPAL pipeline – an onshore branch of the offshore Russian German Nord Stream pipeline –, whilst its attempts to go downstream through the acquisition of European distribution and transmission operators, such as Wingas and DESFA, failed due to current political tensions and the risk of a negative Commission ruling on the operation. Does this mean that the Russian gas behemoth – so often portrayed as the energy arm of the Kremlin – is not so powerful after all? This Policy Brief aims to frame the erosion of Gazprom's power in a wider perspective, analysing its peculiar position at a time of transition, with the global gas business going from a sellers' to a buyers' market, and providing recommendations on how Europe should deal with it. It will be argued that Gazprom – despite still being affected by the Kremlin's political priorities – is moving towards more commercially sound behavior. The EU should profit from this evolution without being tempted by mercantilist options, and rather use the political momentum provided by the energy union to remove barriers to solidarity and to increase competition on the trading platforms.

Towards a U.S. Army officer corps strategy for success : employing talent /

Efficient talent employment is at the core of the Army Officer Human Capital Model. However, the Army's current employment paradigm is unequal to the needs of a professional, volunteer Army facing the twin challenges of a competitive labor market and an increasingly complex global operating environment. It unduly prioritizes "fairness" when making assignments, has a narrowly defined pathway to senior leadership ranks, cannot see the talent it possesses, and suffers from severe principal-agent problems. Optimal employment theories, information age tools, and well-regulated market mechanisms can help the Army match individual officer talents against specific work requirements, reducing risk and achieving the depth and breadth of talent it needs, both now and in the future.

Report on the state and regional development strategy /

In August 1999, the State and Regional Development Strategy Act was signed into law, initiating a multi-year, strategic planning process for economic development in Illinois. In the statute, the General Assembly noted that 'an essential step to assist the Illinois economy, both on a statewide and on a local level, to respond to increasingly competitive global conditions and economic trends is to establish a consensus on a long-term economic development strategy that recognizes both the competitive position of the state's regions and needs of commerce and industry.' The statute directs the Department of Commerce and Community Affairs (DCCA) to implement the strategic planning process.
