  • Teaching load: 63 hours (ECTS credits 9)
  • Lecturers: BOTTAZZI Giulio and GIACHINI Daniele
  • Teaching Assistant: SANTI Caterina
  • Semester: Fall
  • Outline: This course aim to provide a modern theoretical foundation to the most widespread notions and tools in modern finance, including present value theory, real interest rate, arbitrage pricing, portfolio allocation and mean-variance analysis.
  • Objectives: The students should become acquainted with the notion of arbitrage and equilibrium price in different market settings. They should be able to solve the problem of portfolio optimization and mean-variance analysis in rather general terms.
  • Description: General equilibrium, no arbitrage in riskless economies, real interest rate and the yield curve. Arbitrage in security markets, state prices, complete and incomplete markets, valuation functional and the fundamental theorem of finance. Choices under uncertainty, expected utility theory and risk aversion. Portfolio choices, optimal portfolio with multiple risky assets. General equilibrium under uncertainty. Pricing kernel and mean-variance analysis. OPTIONAL: behavioral finance, asset prices under ambiguity, evolutionary finance and the market selection hypothesis.

  • Prerequisites: The course requires a knowledge of linear algebra (linear space, linear map, basis, inversion, eigenvectors and eigensystems), calculus (differential analyses of function of many real variables and static optimization) and, to a lesser extent, probability theory. Some basic knowledge of the theory of choice under uncertainty (utility theory) and economic equilibrium are in general given for granted and only cursorily reviewed.

  • Keywords: financial economics, general equilibrium, arbitrage, asset pricing, optimization
  • Final exam: the get the final grading students are required to pass a final written exam. At least one trial exam will be organized to test your level of preparation. Students get extra points for completing their homework during the course.

Academic Term (Anno Accademico) 2016/2017: advanced calculus

The aim of the course is to provide a deepest introduction to the basic tools and theorems of mathematical calculus. It is taught as a companion courses for second and third year students. Undergraduate courses in the first and second years are oriented to provide a specific set of computational procedures to be applied to the solution of specific problems. The present course might constitute a good complement as it is more concerned with the definition and study of general notions and it is characterized by a theorem-proving approach.
