Obiettivi formativi
This course is designed to provide a rigorous introduction to both modern microeconomics and modern macroeconomics. Its objective is to equip students with the basic analytical tools to read and understand the academic literature and the policy debate on both microeconomic issues (e.g. how consumer choice and firm behaviour are affected by market design and public policy) and macroeconomic issues (e.g. the efficacy and desirability of fiscal and monetary policies).
Risultati apprendimento attesi
For the Advanced Microeconomics module: After the course, students must be able to use economic reasoning to understand the main determinants of individuals' and firms' decisions, the
functioning of markets in real world settings, and how they are influenced by public policies or changes in economic fundamentals. This theoretical knowledge is highly complementary to the data analysis techniques that students will learn in other courses (such as "Research Methods") and are key to a correct understanding and interpretation of the empirical evidence. Students will also acquire the basic knowledge needed to approach more advanced topics in other subfields of economics for which microeconomics is a pre-requisite (e.g. development, education, health, industrial, international, labour, and public economics, among others).

For the Advanced Macroeconomics module: By the end of the course, students will be equipped with analytical tools for improving their knowledge and understanding of some major real-world macroeconomic issues (for example: why delegating monetary policy to an independent central bank? Should government fiscal policy be constrained by rules? Which factors can trigger bank runs or sovereign debt crises? how can government policy help to avoid them? What are the macroeconomic and welfare effects of different social security systems? Can government use fiscal policies to affect economic growth?) Students should know as how to use economic analysis to make informed judgements about macroeconomic issues. Seminar presentations (on a voluntary basis) will enable students both to test their understanding and ability to communicate knowledge of the relevant topics and to discuss real-world macroeconomic issues with their pairs.

Prerequisiti
Students are expected to have fully mastered the following topics: linear algebra, intermediate calculus, static optimization. Introductory knowledge of game theory is useful. Basic knowledge of first-order differential and difference equations (qualitative solution) and of dynamic optimization under certainty is useful for the Advanced Macroeconomics module.
For the Advanced Microeconomics module, students are expected to have a reasonable knowledge of topics taught in introductory and intermediate microeconomics (i.e. consumer and producer theories, partial competitive equilibrium theory). Useful preparatory readings are: Hal Varian, Intermediate Microeconomics: A modern approach, 9th Edition (Last Edition). Regarding Mathematics, Simon, C.P. and Blume, L. (1994), Mathematics for Economists, W. W. Norton & Company, Inc.
For the Advanced Macroeconomics module, students are assumed to be familiar with intermediate macroeconomics taught on textbooks such as O.J. Blanchard (2005 or subsequent editions). Macroeconomics, Prenctice Hall, or S.D. Williamson (2014, fifth edition), Macroeconomics, Pearson.
Modalità di verifica dell’apprendimento e criteri di valutazione
The course is assessed with two distinct examinations, one for the Advanced Microeconomics module (taught in the second term), and the other for the Advanced Macroeconomics module (taught in the third term). The final assessment is based on a written exam. The final written exam consists of both open questions and exercises similar to those that have been solved in the course classes. The final mark will be the weighted average (with equal weights) of the mark obtained in the Advanced Microeconomics exam and of the mark obtained in the Advanced Macroeconomics exam. The Advanced Macroeconomics mark can be topped up by successfull student seminar presentation (on a first-come-first-served voluntary basis). Further details on student seminars will be given at the start of the course (in the third term).

Module Advanced Macroeconomics
Programma
A selection of topics will be chosen among the following and will be announced on the ARIEL website before the start of the course:

Topic 1. Why delegating monetary policy to an independent central bank? (Monetary policy effects in the short and long runs; The Rational Expectations Hypothesis (REH) and the Policy Ineffectiveness Proposition; Credibility of monetary policy: the "inflation bias" problem; Reputation; Central bank Independence; Escape-clause rules and central banking in times of crisis).

Topic 2. Do we need fiscal policy rules? (The Intertemporal Government Budget Constraint; public debt sustainability; fiscal dominance; optimal fiscal policy: tax smoothing; deficit bias; fiscal rules and fiscal councils; seigniorage and inflation).

Topic 3. Coordination failures (Multiple equilibria in macroeconomics; Bank runs and the Diamond-Dybvig (1983) model; Sovereign debt crises and the Calvo (1988) model).

Topic 4. Overlapping generations models and social security (The Samuelson-Diamond two-period OLG model: equilibrium and efficiency; Social security systems; Myopia as a rationale for social security).

Topic 5. Economic Growth (The Ramsey -Cass-Koopmans model with optimal saving: market solution vs. social planner's solution; The AK model of endogenous growth. Government spending in the Ramsey and AK models ).

Topic 6. Macroeconomics and the labour market (Efficiency wage models; Search and matching models; Hysteresis).

Seminar topics will be announced on the ARIEL website before the start of the course. As an example, last year's seminar topics were as follows: i) Central bank independence under threat? ii) Do we need fiscal policy rules? iii) Sovereign debt crises. iv) Pension systems and reforms.
