### Course Syllabus

#### Abstract

This course is an introduction to the modern methods of theoretical and empirical analysis of auctions. We will talk about the four most commonly used auction formats: sealed-bid, open, scoring and double auctions; learn to distinguish them from each other and understand why a given format is chosen in each particular environment. We will learn how to model auctions using games of incomplete information with continuous types, and how to solve these models. A strong emphasis will be put on the mechanism design approach and the application of the envelope theorem. The celebrated revenue ranking result will be discussed. Furthermore, we will learn how models can be used in empirical work, see how these models can be estimated and simulated. At the end of the course students will practice presenting a mock empirical exercise. In the 4th module of 2019/2020 academic year all classes will be switched to online format via ZOOM.

#### Learning Objectives

• know the basics of mechanism design
• know the taxonomy of auctions
• know the basics of theoretical and empirical analysis of auctions

#### Expected Learning Outcomes

• be able to set and solve simple auction models
• be able to estimate and simulate simple auction models
• be able to make a presentation

#### Course Contents

• Course overview and auctions taxonomy
 sealed vs open  multi-unit, multi-dimensional  first vs second price  reserve prices, collusion  auction theory vs empirics: the prime and dual problems
• Equilibria in private value auctions
 first price auctions  second price auctions  revenue comparison  reserve prices
• Introduction to mechanism design
 revelation principle  envelope theorem  revenue equivalence
• Efficiency vs optimality
 IC, IR constraints  efficient mechanisms  optimal mechanisms
• English auctions, common value
• Scoring auctions, Double auctions
• Collusion, Corruption
• Confronting your model with the data
 Estimation, Simulation  Identification, Heterogeneity
• Presenting a mock empirical exercise

#### Assessment Elements

• Homeworks
There will be 5 written homeworks, equally weighted. Fewer problems will be graded than given. The main goal of homeworks is self-practice.
• Midterm exam
• Final exam
The final grade after the first make-up exam is determined by the same formula as after the main exam: GFinal=0.25GMidterm + 0.25GHW + 0.5 GMake-up1 The final grade after the second make-up exam is determined by a different fomula: GFinal=max( GMake-up2 , 0.25GMidterm + 0.25GHW + 0.5 GMake-up2).

#### Interim Assessment

• Interim assessment (4 module)
0.4 * Homeworks + 0.6 * Midterm exam

#### Recommended Core Bibliography

• Auction theory, Krishna, V., 2010
