Value creation around merger waves: The role of managerial compensation

This paper examines the relation between executive compensation and value creation in merger waves. The sensitivity of CEO wealth to firm risk increases the likelihood of out-of-wave merger transactions but has no influence on in-wave merger frequency. CEOs with compensation linked to firm risk have better out-of-wave merger performance in comparison to in-wave mergers. We also present evidence that cross-sectional acquirer return dispersion is greater for in-wave acquisitions. Our results suggest that the underperformance of acquiring firms during merger waves can be attributed in part to ineffective compensation incentives, and appropriate managerial incentives can create value, particularly in non-wave periods.     

‘Information communication technology’ innovation in a non-high technology sector: achieving competitive advantage in the shipping industry

The global marketplace is resulting in an ever-increasing networked and digitalised landscape where organisations compete as integrated supply chains. This paper explores the impact that the digital networked environment has on the traditional shipping services industry. The research contribution has four aspects: (1) most research efforts focus on high technology sectors; this research emphasises the need for information communication technology (ICT) adoption in a non-high technology sector; (2) the research highlights the importance of ICT in achieving competitive advantage in the complex environment of shipping; (3) complexity principles are applied to the discussion on ICT; and (4) the link between ICT and the development of dynamic capabilities is created.     

Convergence of shocks and trade in the enlarged European Union

This paper explores the relation between trade flows and cross-country symmetry of supply and demand shocks using data from the EU-27 countries. Increased bilateral trade intensity is found to have a positive impact on the correlation of both demand and supply shocks. Intra-industry trade is found to be positively linked to correlations of supply-side shocks but negatively linked to correlations of demand shocks. Our results thus provide support for the argument that aggregate demand spillovers and intra-industry trade, rather than specialization, dominate in the process through which trade flows affect the cross-country transmission of shocks in Europe. At the same time, our estimates suggest that monetary-policy convergence in Europe (the circulation of the euro), while having increased symmetry of supply-side shocks, has had no direct favourable impact on symmetry of demand shocks. By contrast, the process of fiscal-policy convergence is found to have resulted in more correlated demand shocks across the EU member states.     

Financial stability indicators and public debt developments

This paper investigates the inter-linkages between financial stability and fiscal policy. It analyzes the effect of selected financial stability indicators on the probability of future debt deterioration, controlling for several macroeconomic variables. We find significant evidence that a fragile banking system can put at risk public finances. Weak bank profitability, low asset quality and a weak capital base increase the fragility of the banking system, thus, raising the probability of future fiscal troubles.     

Boosting confidence: Is there a role for fiscal policy?

This paper investigates the widely held view that expansionary fiscal policy can boost consumer and business confidence, which will stimulate private spending and sustain economic activity. We find evidence in favor of this conjecture, i.e., cuts in direct taxes generate a positive effect on consumer and business confidence, while the same applies in cases of higher non-wage government consumption. However, higher government wage bills and government investment reduce confidence, with the effect being more pronounced when the Debt to GDP ratio is high, possibly because they entail a permanent increase in the size of the public sector, which would have to be financed by higher future taxes.     

Robust monetary policy with imperfect knowledge

We examine the performance and robustness properties of monetary policy rules in an estimated macroeconomic model in which the economy undergoes structural change and where private agents and the central bank possess imperfect knowledge about the true structure of the economy. Policymakers follow an interest rate rule aiming to maintain price stability and to minimize fluctuations of unemployment around its natural rate but are uncertain about the economy's natural rates of interest and unemployment and how private agents form expectations. In particular, we consider two models of expectations formation: rational expectations (RE) and learning. We show that in this environment the ability to stabilize the real side of the economy is significantly reduced relative to an economy under RE with perfect knowledge. Furthermore, policies that would be optimal under perfect knowledge can perform very poorly if knowledge is imperfect. Efficient policies that take account of private learning and misperceptions of natural rates call for greater policy inertia, a more aggressive response to inflation, and a smaller response to the perceived unemployment gap than would be optimal if everyone had perfect knowledge of the economy. We show that such policies are quite robust to potential misspecification of private sector learning and the magnitude of variation in natural rates.     

Inflation, GDP and Causality for European Countries

This study investigates, through panel univariate GARCH models for 14 European countries the causality between inflation and GDP and finds that inflation causes GDP at the 5% level of significance and GDP cause inflation at the 10% significance level. Thus, there is a bidirectional effect between the above two cases which is significant at the 10% level.     

Forecasting and trading high frequency volatility on large indices

The present paper analyses the forecastability and tradability of volatility on the large S&P500 index and the liquid SPY ETF, VIX index and VXX ETN. Even though there is already a huge array of literature on forecasting high frequency volatility, most publications only evaluate the forecast in terms of statistical errors. In practice, this kind of analysis is only a minor indication of the actual economic significance of the forecast that has been developed. For this reason, in our approach, we also include a test of our forecast through trading an appropriate volatility derivative. As a method we use parametric and artificial intelligence models. We also combine these models in order to achieve a hybrid forecast. We report that the results of all three model types are of similar quality. However, we observe that artificial intelligence models are able to achieve these results with a shorter input time frame and the errors are uniformly lower comparing with the parametric one. Similarly, the chosen models do not appear to differ much while the analysis of trading efficiency is performed. Finally, we notice that Sharpe ratios tend to improve for longer forecast horizons.     

The impact of corporate governance,regulatory differences and futures contracts on movements among portfolios of cross-listed equities: The case of Germany

We test the impact of corporate governance effects on the stock price volatility of the DAX100 and find that these variables increase the volatility and decrease the error terms statistically significant. In addition, controlling for contemporaneous and next period's movements, we find that shocks can have a significant impact on the magnitude of stock return co-movements. In particular, our results show that the impact of the German mark/Euro and German bond price index futures shocks have a significant effect on spillovers, on contemporaneous and next period's co-movements related to firms or equities that cross-list on markets with different creditor bankruptcy protection rules. On the other hand, the impact of the German mark/Euro and the German stock price index shocks related to different shareholder protection rules have a smaller impact on both the next period's co-movements and contemporaneous co-movements among or between markets.
