Professor Christopher Passerines said: "It is important to make sure that people do not stay unemployed too long", in commenting on his Nobel Prize in 2010. A worrying feature of the current recession in the United States is that the duration of unemployment has been increasing. Discuss why is Passerines worried? Determine the merits of two policies: (i) increasing the duration of unemployment insurance benefits, (ii) doing aggressive fiscal and monetary expansion that increases aggregate demand for goods and encourages firms to post more vacancies. Write down an essay discussing these two policies.
