This paper examines industrial differences in depreciation rates and the suitability of financial data for a microeconomic analysis. Depreciation is a main source of enterprise investment and serves as a source for replacement of obsolete or used-up capital. The findings on capital structure in this paper are consistent with the common view that heavy industry firms have long-life capital while firms operating in electronics, or light industry as a whole, have a capital structure containing a higher portion of a short-life capital. Also, larger firms are more likely to have a higher portion of long-life capital, like real estate. The last conclusion drawn from this analysis is that certain types of financial data might be highly influenced by seasonal effects which could operate as a measurement error and therefore distort estimates which are sensitive to measurement error.

We empirically assess whether firms face economies and/or diseconomies of scale with respect to air pollution control by evaluating the effects of production on firmlevel air emission levels using a panel of Czech firms during the country's transitional period of 1993 to 1998. By estimating a separate set of production-related coefficients for each individual sector, the analysis permits economies/diseconomies of scale to differ across sectors. More important, the analysis allows these scale effects to vary over time, which seems critical in the context of a transition economy, as the Czech government was tightening air protection polices by imposing more stringent emission limits and escalating emission charge rates. To assess whether these tighter policies expanded economies of scale, the analysis controls for heterogeneity across individual firms by examining intrafirm variation in emissions and production.

Corruption has a negative impact on society and economy. The transition process in Central and Eastern Europe (CEE) uncovered dormant possibilities for corruption and necessity for appropriate steps to be taken. We document the state of corruption in the Czech Republic and the measures introduced to fight it. We cover sectors of society and economy according to their importance of a consequential corruption hazard. We also described the government's program of anticorruption and its achievements and failures. The state of corruption in the country, measured by the Corruption Perception Index, presents a serious problem since the index does not improve as the transition process advances. Numerous comparative studies, however, suggest that corruption is more prominent feature in a number of other transition countries. We believe that the substantial change of approach to the institutional framework is necessary in order to prevent and fight corruption successfully.

It is widely acknowledged that corruption has negative impact on economy and society. Transition process in the Central and Eastern Europe (CEE) uncovered dormant possibilities for corruption that consequently required appropriate steps to be taken against. We attempted to document the state of corruption in the Czech Republic and the measures introduced to fight it. We covered sectors of society and economy according to their importance in the prevention of a corruption and a consequential hazard to the society. We also described the governmental concept of anti-corruption measures and outlined achievements and failures of such a program. The overall impression favors persistent presence of corruption within the society and economy in the Czech Republic. The state of corruption in the country, measured by the Corruption Perception Index, presents a serious problem since the index does not improve as transition process advances. Numerous comparative studies, however, suggest that corruption is more prominent feature in a number of other transition countries. We believe that the institutional framework to prevent and fight corruption appears to be improving.
