Implementation of voting operators

We show that a theory of implementation can be developed in the Aizerman–Aleskerov framework, capturing the main ideas regarding Nash implementation in the Arrovian case. In fact we obtain the counterparts of the results of [Maskin, E., 1977. Nash Equilibrium and Welfare Optimality. MIT, Mimeo] and [Moore, J., Repullo, R., 1990. Nash implementation. A full characterization. Econometrica 58, 1038–1100] in the new framework.     

Financial Crisis and its Asymmetric Macroeconomic Impact on Eurozone Member Countries

The purpose of the paper is to analyze the dynamics of EMU (The Economic and Monetary Union, i.e., the group of European countries who use the common currency euro) and to analyze the fallout from the recent financial and economic dynamics. Both the impact on the eurozone as a whole and on individual member countries will be evaluated. The first 11 years of Eurozone experience will be discussed and evaluated in the second section. The third section will then be devoted to analyzing the fallout from the recent financial and economic dynamics. Both the impact on the eurozone as a whole and on individual member countries will be evaluated. The last section concludes and provides some ideas for future development of eurozone.     

Leverage and firm growth: an empirical investigation of gazelles from emerging Europe

The aim of the paper is to assess the impact of leverage on gazelles’ performance while controlling for firm characteristics, macroeconomic environment, and characteristics of domestic banking sectors. Using a sample of 1105 gazelles from Central, Eastern, and South-Eastern European (CESEE) countries for the period 2006–2014, we find that leverage negatively affects firm growth. The results prove to be robust regarding the use of different estimation approaches, alternatives variables for firm growth, and different sub-samples. Our results suggest that improving access to various sources and types of financing represents a key issue for supporting gazelles’ growth. We also find that macroeconomic environment and banking sector characteristics are important determinants of gazelles’ growth. The economic growth positively influences sales and total assets growth, while the effect of financial and economic development varied with the firm growth measure used. Our findings provide empirical evidence for the need of policy initiatives at national and European Union level to facilitate the growth of small businesses.

     

GIBSON'S PARADOX AND POLICY REGIMES: A COMPARISON OF THE EXPERIENCE IN THE US, UK AND ITALY

This paper compares the behaviour of long-term interest rates and prices in Italy, the UK and the USA, and seeks to shed light into what has become known as the 'Gibson Paradox'. We compare the various theoretical explanations for the observed positive correlation of interest rates and prices in the USA and the UK. Using both regression and frequency domain techniques, we demonstrate that there is little evidence for the occurrence of the paradox in the case of Italy. The key conclusion of the paper is that the comparative evidence from these three countries supports a gold standard interpretation of the Paradox.     

Discretionary rewards as a feedback mechanism

This paper studies the use of discretionary rewards in a finitely repeated principal–agent relationship with moral hazard. The key aspect is that rewards have informational content. When the principal obtains a private subjective signal about the agent's performance, she may pay discretionary bonuses to provide credible feedback to the agent. In accordance with the often observed compression of ratings, we show that in equilibrium the principal communicates the agent's interim performance imperfectly, i.e., she does not fully differentiate good and bad performance. Furthermore, we show that small rewards can have a large impact on the agent's effort, provided that the principal's stake in the project is small.     

How Do Longer Parental Leaves Affect Women’s Workplace Tasks? Evidence from Germany

This study examines how the radical extension of the period of parental leave, from eighteen to thirty-six months, that occurred in Germany in 1992 affected the nature of tasks women performed in their workplaces. The results of the analysis – which used a difference-in-differences method – suggests that this reform had a significant impact on the type of tasks carried out at work by women in the former West Germany. The study finds that after the reform was introduced, the women affected by it performed roles involving significantly less creative and more codifiable tasks than they had done previously. This analysis adds a new dimension to the discussion of the impact of maternity leave legislation on labor market outcomes.     

Monetary Policy Rules, Policy Preferences, and Uncertainty: Recent Empirical Evidence

We survey recent empirical evidence on monetary policy rules, and find that the emphasis in the political economy literature on institutional design (e.g. central bank independence and inflation targeting) is exaggerated. Formal institutional reform seems neither a necessary nor a sufficient condition for the observation of shifts in monetary policy rules. However, there is no doubt that in some cases (e.g. the UK following the start of inflation targeting in 1992, and Bank of England Independence in 1997), a major shift in monetary policy conduct is detectable. We also highlight the problems in explicitly testing the predictions of the political economy literature. Semi-structural modelling approaches, such as time-varying VAR models may be more useful in understanding policy rules, and the interaction between policy shifts and changes in the transmission mechanism.     

Efficient constitution formation and maintenance: The role of “exit”

A constitution will create mutual gains for all parties only if it is negotiated within an environment in which all parties possess viable exit options. The availability of exit options can substitute for a veil of uncertainty, which is difficult to operationalize in real-world settings. An efficient constitution also will be self-enforcing if it contains rules and principles geared to support political and market competition in the post-constitutional society. Again, the notion of exit is a useful way to characterize this condition for constitutional maintenance.
