The Dynamics of Capital Structure in Transition Economies

This paper uses a dynamic unrestricted capital structure model to examine the determinants of the private companies' target financial leverage and the speed of adjustment to it in two transition economies, the Czech Republic and Bulgaria. We explicitly model the adjustment of companies' leverage to a target leverage, and this target leverage is itself explained by a set of factors. The panel data methodology combines cross-section and time-series information. The results indicate that the Bulgarian corporate credit markets were less supply -constrained than those of the Czech Republic during the period under investigation. Bulgariancompanies adjusted much faster to the target leverage than Czech firms. The speed ofadjustment related positively to the distance between target and observed ratio for Bulgarian companies while the relationship was neutral for Czech companies. The conservative policies of Czech banks and the exposure control were likely responsible for the slower adjustment among the larger companies while the opposite were true for Bulgarian banks and companies.     

Trust and economic growth: a robustness analysis

This paper analyses the robustness of results on the relationshipbetween growth and trust previously derived by Knack and Keefer(1997) and Zak and Knack (2001) along several dimensions, acknowledgingthe complexity of the concept of robustness. Our results showthat the Knack and Keefer results are only limitedly robust,whereas the results found by Zak and Knack are highly robustin terms of significance of the estimated coefficients and reasonablyrobust in terms of the estimated effect size. The improvementin robustness is caused by the inclusion of countries with relativelylow scores on trust (most notably, the Philippines and Peru).Overall, our results point at a relatively important role fortrust. However, the answer to the question how large this payoffactually is depends on the set of conditioning variables controlledfor in the regression analysis and—to an even larger extent—onthe underlying sample.

An evaluation of government- sponsored vocational training programmes for the unemployed in urban Russia

This is the first study on the effects of active labour marketprograms such as training in Russia. We use the data from theofficial unemployment register combined with information fromthe follow-up survey in a large industrial city in the year2000. The method of propensity score matching was applied tolearn whether participation in the training programmes increasedthe monthly salaries of participants. The findings suggest thatindividuals tend to benefit from the participation in the trainingprogrammes. However, one year later, this effect disappeared.     

Patents, Invalidity, and the Strategic Transmission of Enabling Information

The patent system encourages innovation and knowledge disclosure by providing exclusivity to inventors. Exclusivity is limited, however, because a substantial fraction of patents have some probability of being ruled invalid when challenged in court. The possibility of invalidity—and an ensuing market competition—suggests that when an innovator's capability (e.g., cost of production) is private information, there is potential value to an innovator from signaling strong capability via a disclosure that transfers technical knowledge to a competitor. We model a product-innovation setting in which a valid patent gives market exclusivity and find a unique signaling equilibrium. One might expect that as the probability that a patent will be invalid becomes low, greater disclosure will be induced. We do not find this expectation to be generally supported. Further, even where full disclosure arises in equilibrium, it is only the less capable who make full disclosures. The equilibrium analysis also highlights many of the novel and appealing features of enabling knowledge disclosure signals.     

The Price-Volatility Feedback Rate: An Implementable Mathematical Indicator of Market Stability

Geometric analysis of iterated cross-volatilities of asset prices is adopted to assess the stability of the (risk-free) measure under infinitesimal perturbations. Perturbations of asset prices evolve through time according to an ordinary linear differential equation (hedged transfer). The decay (feedback) rate is explicitly computed through a Fourier series method implemented on high frequency time series.
