Brazil’s 2014 presidential elections: the interconnection between election news and stock market behavior

This study researches whether there has been abnormal stock market behaviour in Brazil as a consequence of election news (observed via opinion polls), regarding the last Brazilian presidential election, held in October 2014. Via applying event study methodology, the research on the Ibovespa and Petrobras suggests that events in which Rousseff was gaining in share have been subject to negative abnormal returns, and events where Rousseff was loosing in share have led to positive abnormal returns. Moreover, volatility has been significantly elevated during the election period and volume has been found to have slightly increased.

Evidence of the presence of bias in subjective metrics: analysis within a family of experiments

Context: Measurement is crucial and important to empirical software engineering. Although reliability and validity are two important properties warranting consideration in measurement processes, they may be influenced by random or systematic error (bias) depending on which metric is used. Aim: Check whether, the simple subjective metrics used in empirical software engineering studies are prone to bias. Method: Comparison of the reliability of a family of empirical studies on requirements elicitation that explore the same phenomenon using different design types and objective and subjective metrics. Results: The objectively measured variables (experience and knowledge) tend to achieve more reliable results, whereas subjective metrics using Likert scales (expertise and familiarity) tend to be influenced by systematic error or bias. Conclusions: Studies that predominantly use variables measured subjectively, like opinion polls or expert opinion acquisition.

Too cold to handle: EU accession talks with Iceland. CEPS Commentary, 3 June 2013

Recent opinion polls suggest that most Icelanders are against joining the EU. By the same token, however, a majority of those polled are in favour of continuing accession talks. These results show that Iceland’s relationship with the EU is a deeply divisive issue within the country. Although no date for the referendum has been set, the new centre-right coalition may thus want to settle this matter as soon as possible. Should there indeed be a majority in support of continuing negotiations, then Iceland’s accession process will become a complicated and cool affair in the hands of an anti-EU membership coalition government.

Estonia in the eurozone - a strategic success. OSW Commentary No. 53, 2011-06-20

The adoption of the euro in January 2011 topped off Estonia’s integration policy. In the opinion of Estonian politicians, this country has never been so secure and stable in its history. Tallinn sees the introduction of the euro primarily in the political context as an entrenchment of the Estonian presence in Europe. The process of establishing increasingly close relations with Western European countries, which the country has consistently implemented since it restored independence in 1991, has been aimed at severing itself its Soviet past and at a gradual reduction of the gap existing between Estonia and the best-developed European economies. The Estonian government also prioritises the enhancement of co-operation as part of the EU and NATO as well as its principled fulfilment of the country’s undertakings. It sees these as important elements for building the country’s international prestige. The meeting of the Maastricht criteria at the time of an economic slump and the adoption of the euro during the eurozone crisis proved the determination and efficiency of the government in Tallinn. Its success has been based on strong support from the Estonian public for the pro-European (integrationist) policy of Estonia: according to public opinion polls, approximately 80% of the country’s residents declare their satisfaction with EU membership, while support for the euro ranges between 50% and 60%. Since Estonia joined the OECD in 2010 and adopted the euro at the beginning of 2011, it has become the leader of integration processes among the Baltic states. The introduction of the euro has reinforced Estonia’s international image and made it more attractive to foreign investors. The positive example of this country may be used as a strong argument by the governments in Lithuania and Latvia when they take action to meet the Maastricht criteria. Vilnius and Riga claim they want to adopt the euro in 2014. The improving economic situation in the Baltic states will contribute to the achievement of this goal, while an excessively high inflation rate, as in 2007, may be the main impediment1.

Towards Explaining Anti-Foreign Violence in Germany. CES Germany & Europe Working Papers, No. 04.8 (Series 53), 1993

Gennany has recently witnessed a vast increase in anti-foreign violence. Assembling data from a wide variety of recent research, the paper addresses two basic questions: to what extent is the outburst of xenophobic attacks a German peculiarity? and what are the explanations for the mcreasing violence? An analysis of criminal statistics of various European countries and of comparative opinion polls in the European Community shows that Germany has indeed witnessed a growth of anti-foreign sentiment, and a level of violence that is conspicuous from a com­ parative perspective. Four possible determinants of this peculiarity of recent German history are discussed: (1) the growing ethnic and cultural heterogeneity due to the vast increase in immigration from non-European countries; (2) the increasing costs of foreigners' claims on the German welfare state; (3) the economic context of immigration; and (4) the transformation of national identity in the context of German unification. It is shown that neither the rate of immigration nor the position of foreigners in the German welfare state yields satisfactory explanations for the recent upsurge in violence, which only occurred after unification. The key for an explanation lies in a particu­lar macro-constellation that is characterized by the concurrence of a massive wave of immigration with an economic crisis, and with the ethnicization of German national identity in the context of unification. Anti-foreign sentiments do not automatically follow increases in immigration, but grow in a specific political climate to which the political elites actively contribute.

Germany’s ‘refugee’ problem. The most important test for Chancellor Merkel and the grand coalition. OSW COMMENTARY NUMBER 182/11.09.2015 2015-09-11

The rapid increase in the number of immigrants from outside of the EU coming to Germany has become the paramount political issue. According to new estimates, the number of individuals expected arrive in Germany in 2015 and apply for asylum there is 800,000, which is nearly twice as many as estimated in earlier forecasts. Various administrative, financial and social problems related to the influx of migrants are becoming increasingly apparent. The problem of ‘refugees’ (in public debate, the terms ‘immigrants’, ‘refugees’, ‘illegal immigrants’, ‘economic immigrants’ have not been clearly defined and have often been used interchangeably) has been culminating for over a year. Despite this, it was being disregarded by Angela Merkel’s government which was preoccupied with debates on how to rescue Greece. It was only daily reports of cases of refugee centres being set on fire that convinced Chancellor Merkel to speak and to make immigration problem a priority issue (Chefsache). Neither the ruling coalition nor the opposition parties have a consistent idea of how Germany should react to the growing number of refugees. In this matter, divisions run across parties. Various solutions have been proposed, from liberalisation of laws on the right to stay in Germany to combating illegal immigration more effectively, which would be possible if asylum granting procedures were accelerated. The proposed solutions have not been properly thought through, instead they are reactive measures inspired by the results of opinion polls. This is why their assumptions are often contradictory. The situation is similar regarding the actions proposed by Chancellor Merkel which involve faster procedures to expel individuals with no right to stay in Germany and a plan to convince other EU states to accept ‘refugees’. None of these ideas is new – they were already present in the German internal debate.

Cameron’s ‘renegotiations’ (or Russian roulette) with the EU: An interim assessment. CEPS Working Document No. 413/September 2015

Since the May 2015 general election when the Tory Party gained an absolute majority in the House of Commons, Prime Minister Cameron has put his campaign into high gear to get a ‘new settlement’ with the EU and invested much personal diplomacy to try to advance his objective. “What does he really want?” is still heard from other EU leaders, yet his agenda is taking rough shape with calls for results under four headings: “competitiveness, sovereignty, social security and economic governance”. These are only code words, however, for a mixed bag of more specific desiderata, which overall seem to be moderate. Impossible demands have been quietly dropped. Some items will still be tricky to negotiate while others can be placed on the agenda for ongoing EU ‘reform’ that can be widely supported. The Brussels side of the affair thus seems manageable, but the wild cards at home in the UK remain or are becoming even wilder. The standard hazards of the referendum instrument are now exacerbated by the unknown quantity of the new Labour leadership alongside the aggressively Eurosceptic majority of Tory MPs and the great migration crisis, which is translating now into a negative factor for the EU in UK opinion polls. This ostensibly very democratic process is looking more and more like a deadly serious game of Russian roulette.

The Electoral Verdict and After: The Road Ahead for India. Asia Policy Brief 2014/04, June 2014

The convincing victory of the BJP in the 2014 Indian general elections came as a surprise to many. Most opinion polls, which had predicted a win for the Bharatiya Janata Party (BJP) and the National Democratic Alliance (NDA) that it leads, had not anticipated the scale of the party’s victory. The BJP alone won 282 seats and the NDA 336 out of 543 seats in the Lok Sabha, the lower house of Parliament. Two things stand out in the verdict. This is the first time in 30 years that a party won a majority on its own; this is also the worst-ever showing by India’s grand old party, the Indian National Congress, which won a mere 44 seats, 70 less than its previous all-time low in 1999.

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.

Optimal strategies in political elections

In the Majoritarian Parliamentary System, the government has a constitutional right to call an early election. This right provides the government a control to achieve its objective to remain in power for as long as possible. We model the early election problem mathematically using opinion polls data as a stochastic process to proxy the government's probability of re-election. These data measure the difference in popularity between the government and the opposition. We fit a mean reverting Stochastic Differential Equation to describe the behaviour of the process and consider the possibility for the government to use other control tools, which are termed 'boosts' to induce shocks to the opinion polls by making timely policy announcements or economic actions. These actions improve the government's popularity and have some impact upon the early-election exercise boundary. © Austral. Mathematical Soc. 2005.
