20845 - TAXATION, INEQUALITY AND GROWTH

To feel comfortable in this course a student should be familiar with intermediate or advanced concepts in microeconomics, with methods of constrained and unconstrained optimization, and with basic knowledge of univariate and multivariate dierence equations.

The course's target is to understand income and wealth inequality, the forces generating them, and the extent to which policy intervention can aect them. The course includes an empirical documentation of the facts and a synthesis of the mechanisms generating them via analytical dynamic models.

1. The Solow Model of Economic Growth and Basic Endogenous Growth Theory
2. Inequality Across Nations: Development Accounting and Structural Transformations
3. Inequality within nations I: Determinants of the labor share and its evolution in Europe and across the world
4. Inequality within nations II: Determinants of individual Income andWealth inequality, and their evolution over time
5. Introduction to Optimal Income and Wealth Taxation
6. Heterogeneity, Occupational Choice and Innovation
7. Automation, Inequality and Taxation of Robots

At the end of the course student will be able to .. Master concepts such as welfare, inequality, economics growth, financial wealth, tax elasticity, saving rate. Identify the key sources of inequality and economics growth. Describe the appropriate redistributive policy to make aggregate economies less unequal at the minimal cost for allocative efficiency andgrowth. Being able to solve a dynamic model.

At the end of the course student will be able to... Interpret and assess the phenomena and the inequality and long-term dynamics of the aggregate economic systems through economic theory. Choose and apply the proper model to understand which economic policy is more appropriate to solve the trade o between inequality and efficiency.

• Face-to-face lectures
• Exercises (exercises, database, software etc.)
• Individual assignments
• Group assignments

The learning experience of this course includes, in addition to face-to-face lectures, the solution in class of problem sets assigned to students throughout the course. Those exercises allow students to apply the analytical tools illustrated during the course and to solve dynamic models of growth. Home assignements are integral part of the course. In those assignments students are asked to solve formal exercises as well as to perform
descriptive analysis of economic data.

No attending students will not have the problem sets, which only count marginally to the final exam.
