Regional vs. Global Public Goods: The Case of Post-Communist Transition

The paper discusses the role of regional public goods vs. global goods in influencing postcommunist transition in Central and Eastern Europe and former USSR with special attention given to three particular factors: (i) external anchoring of national reform process; (ii) international trade arrangements and (iii) international financial stability. Our main finding is that that the EU, through the Eastern enlargement process, acted as the very effective regional public (club) good provider, whose influence across time and countries was correlated with better transition outcomes. In particular, the consolidation phase in democratization, institution building and structural transformation was successful in countries reforming under EU accession conditionality, but not under other forms of conditionality provided, for example, by the Bretton Woods institutions, . In the area of trade, gains from WTO accession were dwarfed by the impact of the opening of the EU trading block for accession countries. Finally, countries participating in EU integration showed more discipline in maintaining macroeconomic stability, while IMF programs were less effective in inducing stability in the absence of the European factor. This the main reason why CIS countries which got neither the EU accession perspective, nor even trade liberalization offer on the EU lag behind Central European, Baltic and Balkan countries in terms of democratization, rule of law, institutional stability and market-oriented economic reforms. However, due to observed ‘enlargement fatigue’ in the incumbent EU, the future attractiveness of the EU integration perspective and strength of the accessionassociated incentive system (in respect to countries of Western Balkans, CIS and Turkey) comes under question. There is also unclear whether European experience in providing regional public goods can be easily repeated in other geographic regions and to which extended can be used by the providers of global public goods.public goods, post-communist transition, European integration, trade liberalization, international financial stability

The Episodes of Currency Crises in the European Transition Economies

The series of currency crises which hit several developing countries in the 1990s did not leave the emerging market economies of Central and Eastern Europe unscathed. However, contrary to the experience of Mexico in 1995 and South East Asia in 1997-1998, the roots of the crises in our region were usually less sophisticated and easier to identify. Most crisis episodes in the former communist countries fit nicely with the ”first generation” canonical model elaborated in 1979 by Paul Krugman and developed in 1980s by other economists. In this model, fiscal imbalances are the main factor leading to depleting international reserves of the central bank and speculative attacks against national currencies. This was the main reason behind all currency crises in our region, very often closely related to serious microeconomic weaknesses and delays in structural and institutional reforms. The only minor exception was the Czech Republic where the devaluation crisis in May 1997 (of rather limited magnitude) was caused by over-borrowing of the enterprise sector, an unreformed financial sector, and political turmoil rather than by fiscal imbalances and an excessively expansionary monetary policy. This volume, following another collection of similar monographs related to Latin American and Asian regions, presents five episodes of currency crises in Eastern Europe in the second half of 1990s. Four of them were related to post-communist economies and one (Turkey) to a developing economy aiming to integrate with the EU and suffering many macroeconomic and structural weaknesses similar to those of the transition group. Bulgaria in 1996-1997 represents the first episode of a full-scale financial crisis, involving drastic currency devaluation and near-hyperinflation, a banking crisis and a near default on debt obligations. The roots of the crisis were fully domestic and, although severe, were restricted to Bulgaria. Russia's financial crisis in August 1998, despite similar characteristics and domestic roots as in Bulgaria, had an important international dimension. On the one hand, the first speculative attacks against the ruble in the fall of 1997 were triggered by crisis events in Asia, particularly in Hong Kong and Korea. On the other hand, when the Russian crisis erupted, it provoked a huge contagion effect across all the countries of the former USSR. It also caused a big turmoil on all segments of the international financial market, bringing the danger of a recession in the US and other developed countries, and triggering a currency crisis in Brazil few months later. The monographs on Ukraine and Moldova present two case studies of such a contagion effect. However, one should remember that these two economies (as well as most other FSU economies) experienced the same weaknesses and vulnerabilities as in Russia. Thus Russian events could only accelerate the crisis in these countries which was, in any event, hard to avoid. Finally, we present the analysis of the recent financial market crisis in Turkey, which fortunately has been stopped by fast and substantial IMF and World Bank support and has not evolved into a full-scale currency crisis.transition economies, crisis, fiscal policy, Bulgaria, Moldova, Russia, Turkey, Ukraine

Differential cross section measurements for the production of a W boson in association with jets in proton–proton collisions at √s = 7 TeV

Measurements are reported of differential cross sections for the production of a W boson, which decays into a muon and a neutrino, in association with jets, as a function of several variables, including the transverse momenta (pT) and pseudorapidities of the four leading jets, the scalar sum of jet transverse momenta (HT), and the difference in azimuthal angle between the directions of each jet and the muon. The data sample of pp collisions at a centre-of-mass energy of 7 TeV was collected with the CMS detector at the LHC and corresponds to an integrated luminosity of 5.0 fb[superscript −1]. The measured cross sections are compared to predictions from Monte Carlo generators, MadGraph + pythia and sherpa, and to next-to-leading-order calculations from BlackHat + sherpa. The differential cross sections are found to be in agreement with the predictions, apart from the pT distributions of the leading jets at high pT values, the distributions of the HT at high-HT and low jet multiplicity, and the distribution of the difference in azimuthal angle between the leading jet and the muon at low values.United States.

Optimasi Portofolio Resiko Menggunakan Model Markowitz MVO Dikaitkan dengan Keterbatasan Manusia dalam Memprediksi Masa Depan dalam Perspektif Al-Qur`an

Risk portfolio on modern finance has become increasingly technical, requiring the use of sophisticated mathematical tools in both research and practice. Since companies cannot insure themselves completely against risk, as human incompetence in predicting the future precisely that written in Al-Quran surah Luqman verse 34, they have to manage it to yield an optimal portfolio. The objective here is to minimize the variance among all portfolios, or alternatively, to maximize expected return among all portfolios that has at least a certain expected return. Furthermore, this study focuses on optimizing risk portfolio so called Markowitz MVO (Mean-Variance Optimization). Some theoretical frameworks for analysis are arithmetic mean, geometric mean, variance, covariance, linear programming, and quadratic programming. Moreover, finding a minimum variance portfolio produces a convex quadratic programming, that is minimizing the objective function ðð¥with constraintsð ð 𥠥 ðandð´ð¥ = ð. The outcome of this research is the solution of optimal risk portofolio in some investments that could be finished smoothly using MATLAB R2007b software together with its graphic analysis
