tradition of consensus, often defusing labour conflicts and avoiding strikes. Similar models are in use in Finland, namely Comprehensive Income Policy Agreement and universal validity of collective labour agreements. The current polder model is said to have begun with the Wassenaar Accords of 1982 when unions, employers and government decided on a comprehensive plan to revitalize the economy involving shorter working times and less pay on the one hand, and more employment on the other. The polder model is widely, but not universally, regarded as successful incomes management policy. This model is also used in Belgium, hence its name (the "polders" are a region comprising the Netherlands and the northern part of Belgium). New Zealand In 1982, then Prime Minister and Finance Minister Rob Muldoon imposed a simultaneous freeze on wages, prices and interest rates in an effort to curb inflation, despite public resistance. These measures were subsequently repealed by Muldoon's successor David Lange and Finance Minister Roger Douglas. Zimbabwe In 2007, Robert Mugabe's government imposed a price freeze in Zimbabwe because of hyperinflation. That policy led only to shortages.
