Under Erlander, the central pillars of the Swedish welfare state were enacted between 1946 and 1947, a period known as the Social Democratic "Harvest Time." In 1946 and 1947, three major reforms were enacted that introduced a basic pension, general child allowances and sickness cash benefits. The National Housing Board was set up as the central authority providing subsidized loans and rent controls, while the National Labor Market Board was established to coordinate the nationalized local employment offices and supervise the union-controlled but state-subsidized unemployment insurance funds. In 1947, a tax reform was carried out that reduced income taxes in low-income brackets, introduced an inheritance tax, and raised the marginal tax rate for higher tax brackets.
