The national economies of the world can be divided to the scavenger and the predator types. The former are parasitic economies, which feed off the latter. The relationship is often not that of symbiosis, where two parties maintain a mutually beneficial co-existence. Here, one economy feeds off others in a way, which is harmful, even detrimental to the hosts. But this interaction - however undesirable - is the region's only hope. The typology of scavenger economies reveals their sources of sustenance: Conjunctural - These economies feed off historical or economic conjunctures or crises. They position themselves as a bridge between warring or conflicting parties. Switzerland rendered this service to Nazi Germany (1933-1945), Macedonia and Greece to Serbia (1992 to the present), Cyprus aided and abetted Russia (1987 to the present), Jordan for Iraq (1991 to the present), and now, Montenegro acts the part for both Serbia and Kosovo. These economies consist of smuggling, siege breaking, contraband, arms trade and illegal immigration. They benefit economically by violating both international and domestic laws and by providing international outcasts and rogues with alternative routes of supply, and with goods and services. Criminal - These economies are infiltrated by criminal gangs or suffused with criminal behaviour. Such infiltration is two phased: the properly criminal phase and the money laundering one. In the first phase, criminal activities yield income and result in wealth accumulation. In the second one, the money thus generated is laundered and legitimised. It is invested in legal, above-board activities. The economy of the USA during the 19th century and in the years of prohibition was partly criminal. It is reminiscent of the Russian economy in the 1990s, permeated by criminal conduct as it is. Russians often compare their stage of capitalist evolution to the American "Wild West". Piggyback Service economies - These are economies, which provide predator economies with services. These services are aimed at re-establishing economic equilibrium in the host (predator) economies. Tax shelters are a fine example of this variety. In many countries taxes are way too high and result in the misallocation of economic resources. Tax shelters offer a way of re-establishing the economic balance and re-instating a regime of efficient allocation of resources. These economies could be regarded as external appendages, shock absorbers and regulators of their host economies. They feed off market failures, market imbalances, arbitrage opportunities, shortages and inefficiencies. Many post-Communist countries have either made the provision of such services a part of their economic life or are about to do so. Free zones, off shore havens, off shore banking and transhipment ports proliferate, from Macedonia to Archangelsk.
