Course Overview

This 5 hour practical course is available only for students registered for the course Numerical Methods for Fiscal and Monetary Policy Analysis. Through specific examples of state-of-the-art monetary and fiscal policy models (e.g. models with zero-lower bound constraint, financial frictions, forward-guidance, etc.) the computer lab practicals will give participants the opportunity to familiarize with the different routines described in class, and will demonstrate their advantages and disadvantages in terms of accuracy and efficiency. No previous knowledge of numerical methods is required, but a basic knowledge of MATLAB (or another programming language) would be very helpful.

Course overview

The world income distribution, both between and within countries, depends on the interaction between local technologies and global markets. This course will focus on how technology is created by firms, it diffuses across countries and responds to market opportunities. Special attention will be devoted to two major phenomena: automation and the rise of China. Each topic will be studied combining theoretical models with macro and micro data.

Selected Topics

1. The economics of ideas: innovation, creative destruction and firm dynamics
2. Biased innovation, technology diffusion and inequality
3. Explaining economic performance: productivity, misallocation and superstar firms
4. Automation: effects on employment, wages and the labor share
5. Offshoring and the rise of China: effects on employment, wages and innovation

Course Overview

We will cover recent research exploring the relation between firm-level frictions, reallocation of resources, and their aggregate implications. Although a substantial part of the course is devoted to analysing financial factors, we will study a general framework applicable to study also the effects of other frictions.

Selected Topics

i) Stylised facts on firm dynamics;
ii) Dispersion in productivity and misallocation of resources: measurement, theory, and aggregate implications.
iii) Financial frictions and firm dynamics.
iv) Innovation, reallocation, and growth
v) Financial factors, and the misallocation of skilled labour and intangible capital.
vi) Finance, firm dynamics and the business cycle: empirical evidence and theory.

Course Overview

This course provides an overview of the key conceptual and practical questions regarding macro-prudential policy. We first review the theoretical foundations for macro-prudential policy, and develop a macroeconomic workhorse model to think about its costs and benefits. We then turn to the empirical evidence, analyzing both the types of macro-prudential measures used in practice and their effectiveness. We conclude by using our workhorse model to shed light on three key debates regarding macro-prudential policy: (i) What are the trade-offs between the ex ante adoption of prudential policies and ex post interventions during crises?; (ii) Should macro-prudential and monetary policies be conducted in a coordinated fashion?, and; (iii) How should macro-prudential policy react to asset bubbles?

Selected Topics

• Why is macro-prudential policy necessary? A workhorse model
• Macro-prudential policy in practice: measures and outcomes
• Policy trade-offs: prudential policy ex ante vs. cleaning up after the crash
• To what extent should macro-prudential regulation and monetary policy be coordinated?
• Asset bubbles: causes and implications for macro-prudential policy.
