Principles for a European Union''s Public Debt

The EU has neither the power to tax nor the right to run a public debt. We analyze if the EU should receive the right for public indebtedness. We make use of the normative theory of public indebtedness and of positive political economy analysis. Our normative analysis identified specific cases for an appropriate use of public indebtedness. According to the political economy analysis, a misuse of public debt may be possible. As the implementation of strict constitutional constraints can limit this misuse, we propose the assignment of a right to public borrowing to the EU within tight constitutional restrictions.     

Does truth win when teams reason strategically?

We study behavior in the race game with the aim of assessing whether teams can create synergies. The race game has the advantage that the optimal strategy depends neither on beliefs about other players nor on distributional or efficiency concerns. Our results reveal that teams not only outperform individuals but that they can also beat the “truth-wins” benchmark. In particular, varying the length of the race game we find that the team advantage increases with the complexity of the game.     

Emergenz organisationaler Fähigkeiten

The capabilities based view of the firm is a major approach in current strategic management research. It focuses on organizational capabilities as the fundamental unit of analysis and states that firms evolve through evolutionary processes. What organizational capabilities are and how they emerge and evolve are central research questions. Existing research focuses only on partial aspects of the emergence of organizational capabilities. Hence, an integrative framework to address these issues is missing. This contribution aims at developing such an integrative framework by a critical review of existing research. Different perspectives are combined to explain the emergence and evolution of organizational capabilities while focusing on a lifecycle model. This contribution starts with an explanation and a taxonomy of pivotal terms of the capabilities based view. Different ways of the emergence and the development of organizational competencies and their relationships will be systematically explained by examining theoretical backgrounds of evolutionary economics and path dependency theory. This contribution ends with a summary and discusses future research streams.     

Accountability – are We Better off Without It?

Abstract

Public managers increasingly lament about negative effects of accountability. Despite these reports and the importance of accountability in public organizations, it is yet unknown when it has positive or negative effects on managers. Overcoming two major obstacles in accountability research, this study therefore investigates ‘how accountability affects public manager's work behaviour’. Firstly, this study applies a cognitive theory offering a promising way out of the current theoretical dead-end. Secondly, the quasi-experimental research design makes the complex concept of accountability more tangible and findings transferable to practice. Moreover, individual level characteristics such as motivation are used to investigate a potential interaction between contingency and individual level characteristics. Results indicate both positive and negative effects of accountability on work behaviour and hence strongly challenge the positive normative connotation of accountability.     

The impact of government debt on the long-run natural real interest rate – a quantitative evaluation

Persistently low natural real interest rates are a problem for monetary policy and financial stability. I analyse to what extent a permanent increase in government debt that is financed by higher taxes could raise the long-run natural real interest rate. As a measurement tool, I use an incomplete markets model with capital and government bonds. Increasing the public debt/GDP ratio by one percentage point raises the real interest rate by between 0.4 and 1.5 basis points, depending on the degree of inequality generated by the model and the tax instrument used to balance the government’s budget constraint. I also show that the interest rate effect of a change in public debt/GDP predicted by the model is significantly smaller than its empirical counterpart for the US, due to the fact that the model understates the empirical fraction of households that are constrained in their consumption decision.
