Anastasia N. Stepanova -  National Research University The Higher School of Economics, E-mail: [email protected] Anna Alexandrovna Tereshchenko - National Research Institute "Higher School of Economics R&D projects in the pharmaceutical industry are extremely risky and bring benefits in the long-run period. Self-interested managers try to avoid risk and underinvest in R&D. In this paper we study the effect of independent directors, insider ownership and scientific connections on R&D investments. Independent directors and insider ownership can mitigate the agency problem by additional monitoring and convergence of interests. Scientific collaboration promote technological development and increase R&D. The research reveals the difference of the effects in emerging and developed markets.In emerging markets theproportion of independent directors is positively connected with R&D investments. Such results can be explained by the fact that independent directors monitor risk-averse managers that underinvest in risky but perspective projects. Scientific connections significantly positively influence R&D investments. Empirical evidence also shows that companies with a higher proportion of independent directors have more collaborations with scientific institutions in emerging markets. Insider ownership also has no significant influence on R&D investments. Such a result can be explained by the fact that not all the insiders can influence the investment process. Moreover, beneficial owners can lack industry specific knowledge that allows them to monitor the process.  In developed markets the situation is different. The proportion of independent directors is associated with lower R&D investment intensity. As R&D investments are extremely high in developed markets, we suppose that the overinvestment problem can exist.  Thus, better corporate governance can decrease the investments closer to an optimal level. Scientific connections and insider ownership are not a significant factor. The research has wide policy implications. The results can be used by shareholders and government regulating institutions in creating optimal management structures.

Abstract We study the effects of contagion around the global financial crisis (GFC) and the Eurozone crisis periods using German and UK returns, each paired with returns from Central and East European (CEE) stock markets that recently joined the European Union (EU). Using bivariate vector error-correction models (VECMs) estimated in GARCH(1,1), we find strong support for long-run equilibrium conditions. This finding suggests that tests of tail dependence using differenced VARs may be mis-specified when long-run equilibrium conditions apply. Past news has more persistence on current volatility in CEE markets than in the developed markets. Past volatility has more persistence in the developed markets compared to the CEE markets. The T-V symmetrized Joe–Clayton (T-V SJC) copula outperforms all other copulas in goodness-of-fit, including, the T-V Gaussian and Student t copulas. This result is supported by a differenced VAR-GARCH (1,1). For CEE and developed market returns, no more than half of our market pairs exhibit significant increases in lower tail dependence, under the T-V SJC copula. Given the number of paired comparisons, the evidence on joint extreme dependence is weak. As such, CEE stock markets experienced little contagion effects during the GFC and Eurozone crisis periods, contrary to prior results. We find that the legal environment negatively impacts financial development, perhaps causing CEE and the EU markets to be isolated.

Purpose –The purpose of this paper is to forecast the value effect of the SEO announcements based on the BRICS stock markets, and to make comparisons with the US and European markets.Design/methodology/approach –China and Russia are picked as representations of the BRICS based on the analysis of the economic growth of the five countries. Historical data from Shanghai Stock Exchange (SSE) and Moscow Stock Exchange (MSE) between 2010 and 2014 were involved. The authors use the abnormal return to quantify the value effect of SEOs and different models were built with the chosen factors. Modelling tools include EViews and SAS, and comparisons were made among the models.Findings –Positive market reactions were observed within two and three days after the SEOs in SSE and MSE respectively, negative market reactions exist in a long-run period after the announcements. The best model for the prediction is the auto-neural model.Research limitations/implications – The sample size could be larger in order to raise the precision of the prediction.Originality/value – Many empirical studies of the SEOs are based on developed markets. However the emerging markets may react differently. This research focuses on the stock markets in BRICS, which could be seen as representations of the emerging markets, thus could provide ideas and clues for relevant stakeholders in emerging markets before the SEO announcements.Keywords SEO, BRICS, Value effect, Neural Networks, SSE, MSEPaper type Research paper

This study presents the results from a comprehensive out-of-sample test of long-run returns following mergers and acquisitions (M&As). Using a unique sample from 23 frontier markets of almost 800 transactions conducted during the years 1992 to 2016, we implement both cross-sectional tests and time-series examinations based on a calendar-time portfolio approach. Contrary to evidence from developed markets, the M&As in these frontier markets do not lead to abnormal underperformance of acquirers, regardless of whether they paid for the acquisition with cash or stock. The results are robust to many considerations, including subsample and subperiod analysis, alternative formation periods, different portfolio construction approaches.

The paper focuses on the impact of time horizon on risk and return, which usually is the object of discussions about “stock versus bond”. The aim of this paper is to investigate the transformation of risk and return when increasing the investment term, and to determine the impact of the investment horizon on investment results when investing in shares and bonds in Lithuania. The authors are proposing a hypothesis that a long-term investment in shares is not only more profitable, but also less risky than investment in bonds. Research of developed markets indicated that long-term investments in shares were more attractive than in bonds: the risk of shares fell to the risk of bonds, but at the same time, the return of shares remained high. However, there are just a few surveys in this field involving developing markets. Empirical results of this research are based on OMXV index and 10-year government bond data from Lithuania. Our results are different from the research results carried out by authors in developed countries and show that even with an increase in the investment horizon up to 60 months, the risk of shares in Lithuania still remains higher than the risk of bonds, and return of shares is lower than that of bonds. Risk premium for shares is negative during all the periods exceeding 12 months. The results suggest that investors with long-run investment horizons must consider the impact of horizon as well as the development of securities market they invest in.
