Knowledge Based Restructuring in Transition Economies: The Role of Business Environment, Competition and ICT

The knowledge based restructuring is taking into account the fact that after the inclusion of new entrants, ICT based changes are not solely related to the concept of the strategic restructuring of already existing companies. Using the BEEPS 2 data, we find that new firms and exporters are driving the innovation process in the transition economies and that both the availability of ICT and the existence of competitive pressure raise innovation. In addition, favourable business environment is an important positive determinant of the decision to innovate. Business environment indirectly, through strategic restructuring affects sales growth as strategic restructuring represents positive and significant determinant of the performance ICT both directly and indirectly affects performance equation. Subsidies are weakly positively related to knowledge based restructuring. The question of subsidies needs to be more analysed. It is unclear whether subsidies are now becoming more related to the strategic restructuring through a governmental support to certain industrial sectors, or subsidies are linked to defensive restructuring, as a support to deal with redundancies

Instability of Democracy as Resource Curse

We suggest a dynamic game theoretic model to explain why resource abundance may lead to instability of democracy. Stationary Markov perfect equilibria of this game with four players – Politician, Oligarch, Autocrat and Public (voters) – are analyzed. Choosing a rate of resource rent tax, potential Autocrat competes with conventional Politician for the office, and Oligarch, the owner of the resource wealth, bribes Politician to influence her decisions. Actual Autocrat's tax policy may be different from the announced one. If the difference is large, then Public may revolt or Oligarch may organize a coup to throw Autocrat down. It is shown that the probability of democracy preservation is decreasing in the amount of resources if the institutional quality is low enough. It does not depend on the amount of resources, if the institutional quality is higher than a threshold. The level of the threshold, however, depends positively on the resource wealth. We have found also that under very low institutional quality, a paradoxical effect takes place: the probability of democracy preservation may decrease with small improvements of institutional quality. It is shown as well that Oligarch earns larger part of rent under democracy than under autocracy. This result conforms to empirical observation which is demonstrated in the paper: under low quality of institutions, democratization leads to higher inequality and inequality entails worsening of the attitude to democracy

The Impact of Energy Prices on Green Innovation

Based on patent data and industry specific energy prices for 18 OECD countries over 30 years we investigate on an industry level the impact of energy prices on green innovation activities. Our econometric models show that energy prices and green innovation activities are positively related and that energy prices have a significantly positive impact on the share of green innovations in non-green innovations. More concretely, our main model shows that a 10% increase of the average energy prices of the previous five years results in a 2.7% and 4.5% increase of the number of green innovations and the share of green innovations in non-green innovations, respectively. We also find that the impact of energy prices increases with an increasing lag between energy prices and innovation activities. Robustness tests confirm the main results

An Outlier-Robust Extreme Bounds Analysis of the Determinants of Health-Care Expenditure Growth

Hartwig (2008) has presented empirical evidence that the difference between real wage growth and productivity growth at the macroeconomic level is a robust explanatory variable for deflated health-care expenditure growth in OECD countries. In this paper, we test whether this finding is robust to the inclusion of additional covariates, applying different versions of Extreme Bounds Analysis (EBA) to data for 33 OECD countries over the period 1970-2010. As far as it is statistically feasible, all macroeconomic and institutional determinants of health-care expenditure growth that have been suggested in the literature are included in the EBA. Furthermore, we analyse to what extent outliers in the data influence the results using an outlier-robust MM estimator. Our results confirm Hartwig's earlier finding. A number of additional both covariate- and outlier-robust determinants are also identified
