The Trader economies - These economies are equivalent to the cardiovascular system. They provide the channels through which goods and services are exchanged. They do this by trading or assuming risks, by providing physical transportation and telecommunications, and by maintaining an appropriately educated manpower to support all these activities. These economies are highly dependent on the general health of international trade. Many of the CEE economies are Trader economies. The openness ratio (trade divided by GDP) of most CEE countries is higher than the G7 countries'. Macedonia, for instance, has a GDP of 3.6 Billion US dollars and exports and imports of c. 2 billion US dollars. These are the official figures. Probably, another 0.5 billion US dollars in trade go unreported. Additionally, it has one of the lowest weighted customs rate in the world. Openness to trade is an official policy, actively pursued. These economies are predatory in the sense that they engage in zero-sum games. A contract gained by a Slovenian company - is a contract lost by a Croatian one. Luckily, in this last decade, the economic cake tended to grow and the sum of zero sum games was more welfare to all involved. These vibrant economies - the hope of benighted and blighted regions - are justly described as "engines" because they pull all other (scavenger) economies with them. They are not likely to do so forever. But their governments have assimilated the lessons of the 1930s. Protectionism is bad for everyone involved - especially for economic engines. Openness to trade, protection of property rights and functioning institutions increase both the number and the scope of markets. Return Market Impeders and Market Inefficiencies Even the most devout proponents of free marketry and hidden hand theories acknowledge the existence of market failures, market imperfections and inefficiencies in the allocation of economic resources. Some of these are the results of structural problems, others of an accumulation of historical liabilities. But, strikingly, some of the inefficiencies are the direct outcomes of the activities of "non bona fide" market participants. These "players" (individuals, corporations, even larger economic bodies, such as states) act either irrationally or egotistically (too rationally).
