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.

According to this article, Germany's unemployment had increased for a fifth month in august. The unemployment rate is currently at 6.8%. This increase in unemployment was a consequence of the European debt crisis, which had severely decreased demand for exports, causing companies to hold back on investments.  These two factors have therefore decreased both aggregate demand (net exports decrease) and aggregate supply (decrease in investments). Therefore fewer jobs are required as less output is being demanded. This is shown by the numerous job cuts which have occurred throughout Germany. "Siemens AG (SIE) said on Aug. 27 it will cut 500 jobs at its German factories making industrial gear boxes and clutches by 2016, citing slack demand".   However, the article states that the unemployment rate is still the lowest it has been for the past two decades, and meanwhile wages are rising. This increase in wages is boosting consumer spending, therefore causing an increase in aggregate demand, which should eventually allow for aggregate supply to increase, and therefore increasing the need for workers.  Moreover, although unemployment has risen in Germany, it still does not yet compare to the 8.2% unemployment of the US, the 10.8% in Italy, and the euro-area average of 11.2%. 

China faces some serious economic problems. One main problem is that China seems to be suffering from excess capacity resulting from an overinvestment in factories, retail stores or infrastructure which leads to an imbalanced supply and aggregate demand relation. Aggregate demand is the total demand for a nation's goods and services from domestic households, firms, the government and foreigners. The article reveals two different approaches to evaluating China's economy: the Keynesian theory and the Austrian school theory. The Keynesians argue that aggregate demand drives stability and that governments can and should help in difficult times. The Chinese government has the tools to increase aggregate demand as it could for example "adjust interest rates and bank reserve requirements, instruct state-owned banks to maintain lending", deploy foreign exchange reserves, or initiate construction and infrastructure projects. On the other hand, the Austrian school of economics believes that it is hard for the government to invest money wisely, particularly in China, where there seems to be an environment of "economic favoritism". The Keynesians may believe that China will be able to manage its overcapacity; however, the Austrian theory argues that the Chinese government will distort resource allocation and further limit aggregate demand. - Julieta Fischer

The unemployment rate in Scotland has increased to 8.2 percent within the last three months. It is now worse than the UK unemployment rate, which is at about 8.1 percent.In order to fix the problem, the government has now decided to step in, in order to achieve economic growth and get people back into work. The government wants to do this by simplifying the business environment and reform the tax system for companies in order to help them create more jobs. By decreasing the costs of production, the government wants the SRAS curve to shift to the right and therefor increase aggregate supply. If costs of producing are lower, firms will higher more workers, which will result in less unemployment according to theory.
