The many foreign advisers from, principally, the United States, the United Kingdom and Sweden were often under contract to the international financial institutions and bilateral or multilateral technical assistance programmes. They favoured free trade and exchange rate convertibility rather than trade protection and capital controls, which might have checked capital flight. They tended to support privatization without prior industrial restructuring; an exception was to be found in Eastern Germany where the Treuhand (Trust Agency) prepared state-owned enterprises for the market at considerable cost to the government. Western technical assistance programmes were established by European Union – through the Phare and TACIS programmes – and other donors (including the US AID, the UK Know-how Fund and UNDP) and by the IMF, the World Bank, EBRD and KfW, which also advanced loans for stabilization, structural adjustment, industrial restructuring and social protection. Technical assistance was delivered through the exchange of civil servants and by management consultants, including Agriconsulting, Atos, COWI, Ernst & Young, GOPA, GTZ, Human Dynamics, Idom, IMC Consulting, Louis Berger, NIRAS, PA Consulting, PE International, Pohl Consulting, PwC, and SOFRECO.
