Recent years are seeing higher quality management in transition countries. Reasons for this trend include improved education, opportunities to study and work abroad, and changes in work habits caused by companies investing locally. Economic transition is expensive. The governments of many countries in transition cannot afford all the investments required of them. Economic transition and reform make deep cultural impressions on a nation's people. It can, in many cases, lead to culture shock. The environment in these countries become highly polluted. Countries in transition often suffer periods during which the negative effects of a market economy seem to outweigh its benefits.
