This is a master level introductory course on modern macroeconomics. Students will learn basic analytical tools, such as dynamic analysis and optimization, to study how capital, investment and consumption are (or should be) allocated over time, and how rational individuals make choices related to consumption, savings and asset accumulation in competitive markets. The course is divided into two distinctive parts. Part I focuses on growth theories and optimal capital accumulation. Part II focuses on savings, consumption, asset pricing, risk in competitive market economies and some basic properties of competitive equilibria.
