An economic depression that began in 1972 was exacerbated by capital flight, plummeting private investment, and withdrawal of bank deposits in response to Allende's socialist program. Production fell and unemployment rose. Allende adopted measures including price freezes, wage increases, and tax reforms, to increase consumer spending and redistribute income downward. Joint public-private public works projects helped reduce unemployment. Much of the banking sector was nationalized. Many enterprises within the copper, coal, iron, nitrate, and steel industries were expropriated, nationalized, or subjected to state intervention. Industrial output increased sharply and unemployment fell during the Allende administration's first year.
