The objective of the course is to develop the analytical tools to think about short-run macroeconomic policy issues. The course will first introduce the theory of intertemporal consumption choices that has a central role in many macro applications, highlighting the role of uncertainty and liquidity constraints in shaping the lifetime profile of consumption and savings. It will then discuss the stabilization role of fiscal and monetary policy along the business cycle. The course will cover both the basic real business cycle model and New-Keynesian models of asymmetric information and imperfect competition with small menu costs. The final part of the course will discuss the role of labour and financial markets frictions on business fluctuations.
Grades will be based on a final exam.
1. Intertemporal choices: consumption and savings (Romer, 2011, ch. 8)
2. The real business cycle model (Romer, 2011, ch. 5)
3. Microfoundation of nominal rigidities:
- asymmetric information (Lucas, 1972)
- small menu costs (Blanchard and Kiyotaki, 1987; Fischer, 1977; Caplin and Spulber, 1987)
4. The role of labour and nancial markets imperfections on business fluctuations
- Unemployment fluctuations and labour market dynamics (Diamond, 1982; Cooper and John, 1988; Mortensen and Pissarides, 1994)
- Credit rationing, credit cycles and systemic risk (Stiglitz and Weiss, 1981; Kiyotaki and Moore, 1997; Bernanke and Gertler, 1989; Bernanke, Gertler, and Gilchrist, 1999; Douglas and Dybvig, 1983).
