The Adverse Effect of Contingent Convertible Bonds on Bank Stability
IWH Discussion Papers,
This paper examines the impact of issuing contingent convertible (CoCo) bonds on bank risk. I apply a matching-based difference-in-differences approach to banklevel data for 246 publicly traded European banks and 61 CoCo issues from 2008−2018. My estimation results reveal that issuing CoCo bonds that meet the criteria for additional tier 1 (AT1) capital results in significantly higher z-scores one to three years after the issuance. Rather than having a net negative impact, issuing CoCos seems to impede a positive time trend towards greater bank stability. This study adds to the empirical literature on the risk-effect of contingent convertibles by identifying the causal effect of AT1 CoCo bonds on reported risk changes over a three-year post-treatment horizon based on a comprehensive sample of European banks. The results confirm theoretical predictions that currently outstanding CoCo bonds create incentives for excessive risk-taking.

German Unification: Macroeconomic Consequences for the Country
F. Heinemann, U. Klüh, S. Watzka (eds): Monetary Policy, Financial Crises, and the Macroeconomy. Springer,
This paper shows basic macroeconomic consequences of the German unification for the country in time series spanning from 20 years before the event until 25 years thereafter. Essential findings can well be explained by elementary economic theory. Moreover, it is shown that the German economy had been off steady state already before unification in important aspects. In particular, a steep increase in the current account balance during the 1980s suggests that globalization strongly affected the German economy at that time. While unification stopped the trend to an ever more open economy and to a rising trade surplus for about 10 years, the fall of the iron curtain eventually even increased this trend in the long run.
Knowledge Spill-overs for Knowledge-based Development: Progression in Theory and Obstacles for Empirical Research
International Journal of Knowledge-Based Development,
As scientists and policymakers tend to interpret changes in the economy as a trend towards an increasingly knowledge-based economy, their recommendations and strategies for regional economic development frequently contain elements how to intensify the knowledge flows in the region concerned. Knowledge flows come into existence from intentional action, but also in an unintended way as externalities or knowledge spillovers. This paper reviews the ways regional and urban economics has dealt with the concept of knowledge spillovers. Knowledge spillovers are defined within a conceptual framework that points out different uses of knowledge in economics. The concept’s operationalisations in diverse empirical studies are systematised and discussed. After a critical review of the current state of research, policy strategies aiming to intensify knowledge spillovers are classified. The paper concludes with an outlook on promising new approaches to research knowledge spillovers and on the elaboration of more efficient policy strategies.
