The black economy is made up of two constituent activities: 1. Legal activities that are not reported to the tax authorities and the income from which goes untaxed and unreported. For instance: it is not illegal to clean someone's house, to feed people or to drive them. It is, however, illegal to hide the income generated by these activities and not to pay tax on it. In most countries of the world, this is a criminal offence, punishable by years in prison. 2. Illegal activities which, needless to say, are also not reported to the state (and, therefore, not taxed). These two types of activities together are thought to comprise between 15% (USA, Germany) to 60% (Russia) of the economic activity (as measured by the GDP), depending on the country. It would probably be an underestimate to say that 40% of the GDP in Macedonia is "black". This equals 1.2 billion USD per annum. The money generated by these activities is largely held in foreign exchange outside the banking system or smuggled abroad (even through the local banking system). Experience in other countries shows that circa 15% of the money "floats" in the recipient country and is used to finance consumption. This should translate to 1 billion free floating dollars in the hands of the 2 million citizens of Macedonia. Billions are transferred to the outside world (mostly to finance additional transactions, some of it to be saved in foreign banks away from the long hand of the state). A trickle of money comes back and is "laundered" through the opening of small legal businesses. These are excellent news for Macedonia. It means that when the macro-economic, geopolitical and (especially) the micro-economic climates will change - billions of USD will flow back to Macedonia. People will bring their money back to open businesses, to support family members and just to consume it. It all depends on the mood and on the atmosphere and on how much these people feel that they can rely on the political stability and rational management. Such enormous flows of capital happened before: in Argentina after the Generals and their corrupt regime were ousted by civilians, in Israel when the peace process started and in Mexico following the signature of NAFTA, to mention but three cases. These reserves can be lured back and transform the economy. But the black economy has many more important functions. The black economy is a cash economy. It is liquid and fast. It increases the velocity of money. It injects much needed foreign exchange to the economy and inadvertently increases the effective money supply and the resulting money aggregates. In this sense, it defies the dictates of "we know better" institutions such as the IMF. It fosters economic activity and employs people. It encourages labour mobility and international trade. Black economy, in short, is very positive. With the exception of illegal activities, it does everything that the official economy does - and, usually, more efficiently.
