The 2014 European Elections in Poland: Are we in for another uninspiring campaign? EPIN Commentary No. 15, 20 December 2013

In previous European elections, Polish political parties were not able to draw a large number of voters to the polling stations. Poland stood out in the European Union mainly by its extremely low turnout. In light of the current situation in the Polish political scene, this EPIN Commentary predicts that the chances are that the 2014 electoral campaign will also be lacklustre, focused on domestic issues, resulting yet again in a disappointing turnout.

A Legal and Economic Assessment of European Takeover Regulation. CEPS Paperbacks. December 2012

Takeovers are one-off events, altering control and strategy within an organisation. But the chances of becoming the target of a bid, even where remote, daily influence corporate decision-making. Takeover rules are therefore central to company law and the balance of power among managers, shareholders and stakeholders alike. This study analyses the corporate governance drivers underpinning takeover bid regulations and assesses the implementation of the EU Directive on takeover bids and compares it with the legal framework of nine other major jurisdictions, including the US. It finds that similar rules have different effects depending on company-level and country-level characteristics and considers the use of modular legislation and optional provisions to cater for them.

Ukraine in deadlock - What next? EPC Commentary, 12 February 2014

Some two months since Ukrainians took to the streets, a political solution to the standoff between the EuroMaidan protestors and the Ukrainian authorities remains out of reach, with the situation on the ground remaining volatile. As the clock ticks there is fear that further violence and instability could be on the horizon. Further turmoil risks Ukraine’s territorial integrity, with talk of division and calls for Moscow to intervene coming from a number of Party of Regions speakers. It also increases the likelihood of new security threats going beyond Ukraine’s border including refugees and asylum seekers. Furthermore, as the political crisis deepens, Ukraine’s economic situation becomes more perilous with the chances of default on its debts rising.

Croatia: accession negotiations with the EU overshadowed by parliamentary elections. OSW Commentary No. 48, 2011-02-29

In 2011 Croatia entered the final stage of its accession negotiations with the EU. The completion of these negotiations will probably coincide with the parliamentary elections which should be held in November or December this year. The elections are likely to bring about a change of government, as public support for Jadranka Kosor's cabinet and her party, the Croatian Democratic Union (HDZ) has been declining; the left-wing opposition is likely to take power. Therefore, the government’s main goal is to complete the accession negotiations in the first half of the year, in order to sign the accession treaty and hold the EU membership referendum before the parliamentary elections. The HDZ believes that only the successful completion of the accession negotiations could increase its chances of a good result in the upcoming elections. At the same time, fearing a further fall in support, the government will avoid any decisions and reforms that would be controversial for the public, especially in the sphere of the economy; such decisions could also increase Euroscepticism among the Croatian public, and result in the rejection of EU accession in the referendum. The government in Zagreb hopes that the currently implemented anti-corruption strategy and reform of the judiciary, as well as the advanced process of adaptation to EU conditions, will be enough to complete the negotiations. This strategy has a serious chance of success, considering that there is considerable support for Croatia's membership among the EU countries and institutions. Another reason is that further prolongation of the negotiations could aggravate hostility towards the EU among the Croatian public, and would be a bad sign for other Balkan states with membership aspirations. However, subordinating Croatian policies to the completion of negotiations in the first half of the year could prove to be adverse for Croatia itself in the longer term, as it would put off the necessary structural reforms.

Tug-of-war over EU's policy towards its neighbours. OSW Commentary No. 49, 2011-03-09

The revolutions in North Africa, the approaching end of the ‘strategic review’ of the European Neighbourhood Policy (ENP) initiated by the European Commission, and the beginning of negotiations on the European Union’s new financial perspective, have intensified the debate among the member states and EU institutions on what policy the EU will adopt towards its neighbourhood in the future. The discussion concerns not only the shape of the ENP but also non-ENPI foreign policy instruments which Brussels applies towards neighbouring countries, such as the thematic instruments and loan support. Serious differences of opinion have emerged among the member states. The countries located in the southern part of the EU want Brussels to boost its policy towards North Africa, even at the expense of engagement in Eastern Europe and the Southern Caucasus. Meanwhile Central European countries, including Germany, favour a more balanced approach towards both directions. The future shape of the ENP, as well as the EU’s other foreign policy instruments, will have a strong impact on the approach the EU adopts towards its Eastern neighbourhood. If some of the proposals are realised, especially the southern member states’ request to transfer some of the funds from the Eastern to the Southern neighbourhood, the chances of meeting the Eastern Partnership goals, such as the association of the partner countries with the EU and the creation of deep and comprehensive free trade areas, could be reduced.

Systemic crisis in Alexander Lukashenko's regime. OSW Commentary No. 66, 2011-10-28

Measures undertaken by the Belarusian government in the areas of the economy, internal affairs and foreign policy in recent months have proven increasingly ineffective. Despite the deteriorating macroeconomic situation, Minsk is not implementing the reforms necessary to combat the crisis and its activity is limited only to feigned actions and administrative regulations. As a result, the economic situation is worsening but the chances of obtaining external loans as support, for example from the International Monetary Fund (IMF), are decreasing. At the same time there is mounting fear among the regime of social unrest, therefore by raising salaries of the least well-off groups of citizens it is trying to compensate for the increased costs of living. On the other hand, the government is extending the scope of control over society and competences of enforcement bodies. Belarus’s room for manoeuvre in foreign policy has also been diminishing substantially. Despite the EU’s declared willingness to reach an agreement and its encouragement, Lukashenko is not ready to make concessions in the political sphere (e.g. to rehabilitate political prisoners), and this is hindering the normalisation of relations with the West. Minsk furthermore feels a mounting pressure from Moscow, making the Belarusian negotiating position ever weaker. The lack of freedom of manoeuvre in foreign policy, no possibility to maintain a costly economic model and the lack of support from the majority of society all prove that Alexander Lukashenko’s regime is in severe crisis. The system he established is no longer able to respond to current threats with adequate and effective strategies. This situation is challenging the regime’s stability and calls into question its viability in the longer term.

Flashlight Europe N°7–09 July 2015. Greece After the Referendum: Three Possible Scenarios for the Euro Area

About ten days ago Alexis Tsipras, the Greek prime minister, announced that there was going to be a referendum, and thus terminated the negotiations on a new rescue package unilaterally. Since then the euro area has been plunged into a wholly unprecedented political crisis. Whether or not Greece can re-main in the monetary union is more uncertain than ever, and decisions that can give a new twist to the political and financial situation are being made almost every day. The Greek banks have been closed for over a week. The economic data are deteriorating rapidly. And yet a solution is nowhere to be seen. The No vote in the Greek referendum has not exactly improved the chances of reaching an agree-ment. For the time being the positions seem to have become uncompromising. At the summit of the heads of state and government on 7 July the Greek government was given five days and a “final deadline” in order to come up with viable proposals for reform. Thus the next few days are of crucial im-portance. At the weekend the heads of state and government of all 28 EU member states are going to meet in order to decide the future of Greece. This flashlight europe provides an overview of the events of the last few days, outlines possible scenarios for what may happen in the near future, and identifies factors which may exert an influence in the short term. We are not trying to give an exact forecast or to formulate action recommendations. But we are trying to shed some light on a confusing situation by identifying important patterns and some of the salient factors.

A close call before Paris. CEPS Commentary, 2 November 2015

Following the final negotiating session in Bonn, October 19-23, and in the run-up to COP21 in Paris, which is expected to culminate in a new global climate agreement in December, Andrei Marcu offers his assessment of this immensely complicated and important project and its chances to succeed. In his view, the latest version of the text allows all countries to feel ownership and can succeed if sufficient political will can be summoned.

On the Road to Democracy? Political Liberalization in Myanmar. Asia Policy Brief 2014/01, January 2014

Myanmar’s liberalizing reforms initiated by President Thein Sein after taking office in March 2011 are raising high hopes of peace and democracy in the country. Progress, after nearly three years, has however been uneven: there have been positive developments in the area of press freedom, with regard to political prisoners and in dealing with the political opposition. At the same time the dialogue with ethnic groups has stagnated and ethnic and religious violence has escalated. This Asia Policy Brief critically assesses the reform policy and weighs up the chances of democratization of the long-time military regime.

Father, Mother, Child? Eight Trends in Family Life for Policymakers to Keep in Mind. Summary

The family is the first context for a child’s development, and the most important. This is where children begin to develop their own identities and first experience a sense of closeness, community and security. Family is a domain where learning takes place – for all generations. In their daily interactions, children, mothers and fathers learn from and with one another. They develop empathy and a sense of responsibility, and learn to deal with conflict. Values, beliefs and norms, passed on from parents to children, evolve in the course of everyday life. Thus parents exert an enormous influence on their children’s educational opportunities and overall life chances – as research in Germany and other countries has clearly shown.

Scotland and the European Union. EPC Policy Brief, 14 July 2016

Britain’s referendum on EU membership revealed a country divided; while the United Kingdom voted to leave by 52%, Scotland voted by 62% to remain in the EU, putting the question of Scottish independence back on the table. The Scottish government says that Scotland should not be taken out of the EU against the will of its people, and that a second referendum on independence is “highly likely”. Although the Scottish people voted against independence in a referendum in 2014, opinion polls currently suggest that a majority in Scotland wants another referendum, and would vote for independence. In this Policy Brief, Graham Avery looks at how the Scottish question relates to the UK’s withdrawal from the EU; what factors have changed since the Scottish people voted against independence in 2014 and what Scotland‘s chances are of remaining in the EU.

Trust and Reputation in Internet Auctions

Exchange between anonymous actors in Internet auctions corresponds to a one-shot prisoner's dilemma-like situation. Therefore, in any given auction the risk is high that seller and buyer will cheat and, as a consequence, that the market will collapse. However, mutual cooperation can be attained by the simple and very efficient institution of a public rating system. By this system, sellers have incentives to invest in reputation in order to enhance future chances of business. Using data from about 200 auctions of mobile phones we empirically explore the effects of the reputation system. In general, the analysis of nonobtrusive data from auctions may help to gain a deeper understanding of basic social processes of exchange, reputation, trust, and cooperation, and of the impact of institutions on the efficiency of markets. In this study we report empirical estimates of effects of reputation on characteristics of transactions such as the probability of a successful deal, the mode of payment, and the selling price (highest bid). In particular, we try to answer the question whether sellers receive a "premium" for reputation. Our results show that buyers are willing to pay higher prices for reputation in order to diminish the risk of exploitation. On the other hand, sellers protect themselves from cheating buyers by the choice of an appropriate payment mode. Therefore, despite the risk of mutual opportunistic behavior, simple institutional settings lead to cooperation, relatively rare events of fraud, and efficient markets.

On the prospective detection of polyoxymethylene in comet 67P/Churyumov–Gerasimenko with the COSIMA instrument onboard Rosetta

The presence of polyoxymethylene (POM) in cometary grains has been debated years ago. Although never proven, its presence can not be excluded. Rosetta, the ESA mission to comet 67P/Churyumov–Gerasimenko, may answer this question. On board the spacecraft, COSIMA (COmetary Secondary Ion Mass Analyzer) will analyze the grains ejected from the nucleus using a Time Of Flight Secondary Ion Mass Spectrometer (TOF-SIMS). In this paper we report the extent to which COSIMA will be able to detect POM if this compound is present on cometary grains. We have analyzed two kinds of POM polymers with a laboratory model of COSIMA. Positive mass spectra display alternating sequence of peaks with a separation of 30.011 Da between 1 and 600 Da related to formaldehyde and its oligomers but also to the fragmentation of these oligomers. The separation of 30.011 Da of numbers peaks, corresponding to the fragmentation into H2CO is characteristic of POM and we show that it could be highlight by mathematical treatment. POM lifetime on COSIMA targets have also been studied as POM is thermally instable. It can be concluded that the cometary grains analysis have to be planned not too long after their collection in order to maximize the chances to detect POM.
