EXPERTS have warned against pessimism and gloom in Germany and the federal government has implemented measures to stimulate the economy and reduce debt burdens to help the country save, consolidate and grow. Without the special financial burdens of reunification, Germany would continue to be without peer in the listings of most economic and monetary parameters. Reunification has brought into line two incompatible economic systems, and re-integrated the former socialist eastern Germany - the new states - into a free market economy. The impact has been enormous. However, the financial and economic shape of Germany compares favourably with that of other big industrial nations. This is also despite huge funding transfers and complex sums the government has devoted to restructuring assistance to nations in eastern and central Europe. These transfers into the new states contributed substantially to arresting the European impact of the global recession. Chancellor Helmut Kohl and Gunter Rexrodt, the Economics Minister, are optimistic about the success of a ''solidarity pact'' between all the responsible financial and economic forces. The pact's aim is to create a sound, federative financial constitution that will make unification a success. For the first time, several economic indicators have improved, in particular the turnover in the retail trade, the assessment of the business climate and the demand in the building trade. Forecasters are predicting the trend will improve and hopes in Bonn are being pinned on international developments, such as the emerging cyclical change in the United States and the impulses generated by the European Community's internal market. The federal government has met the growing financial needs of the eastern German federal states by adopting a wide range of budgetary measures to save and consolidate. In 1991 and last year, spending was tightened to save more than 60 billion German deutschemarks. The cuts under the Federal Consolidation Programme of March saved a further 18 billion deutschemarks. The most recent round of budgetary cuts will relieve the 1994 budget of more than 20 billion deutschemarks. The government deficit - about four per cent of the Gross National Product - puts Germany in the middle of the Group of Seven (G-7) nations. It must be noted that Germany is more active than other G-7 nations in trying to control the structural deficit. Its ratio of public debt to Gross Domestic Product - at just under 50 per cent - is the lowest among the G-7. This is despite a steep rise in public borrowing sparked by the cost of transforming the economy, infrastructure and social systems of the new states. The debt surge barely dented the stability of the German economy and currency. Even so, the government is still working hard to encourage economic growth. It has moved to institute measures to reduce public deficits, making it easier for interest rates to fall and to stabilise consumer and investor expectations. It aims to encourage more corporate investment by trying to avoid tax increases. Subsidy cuts and reduced government spending aim to make better use of resources. The Brussels Commission still sees Germany playing a key role in overcoming the economic slump. This is forcing the federal government and the Bundesbank to perform a difficult balancing act between internal stability and the urgent requests from other countries to generate German growth incentive. For a long time, the Bundesbank reacted with a strict stability policy but, last autumn, it embarked on a cautious policy of interest rate reduction. The move was met with relief around the world: lower interest rates make investments and consumer credit cheaper, fostering crucial economic growth.
