The article describes how unemployment in Argentina has dropped below 7% for the first time in a long time. The decreased unemployment is due to an increase in the country's exports and an increase in national aggregate demand. Both of these things would cause an increase in aggregate supply, which in result would increase the aggregate supply of labor, causing the unemployment rate to decrease. However, this is only seen as a short term change, as the export are expected to decrease due to the economic crisis in Europe, and the increasing movement of production to china, and the growing competition from Chinese produced goods, because of the cheaper prices. This would cause aggregate demand in Argentina to decrease, which would cause a response from the short run aggregate supply, in the form or a decrease. This would again cause the aggregate supply of labor to fall back down again, resulting in the unemployment rate rising again.
