ECONOMICS AND LAW
The Economics & Law course examines the legal behaviours and juridical norms in the broadest context of socio-economic and political institutions to assess through social cost benefit analysis of institutional and regulatory options.
It aims at preparing lawyers to better understand how legal and insti-tutional contexts modify incentives and affect socio-economic beha-viours, as well as to assess legislations and institutions (for example within the context of international organization, such as the World Bank, IMF, EBRD, etc.).
The effectiveness of standards, laws and regulations necessarily depend on the socio-economic behaviour of citizens, influenced by the incentives created by implemented policies (e.g. their enforcement). The course will provide an in-depth analysis of public institutions, devoting special attention to efficiency and equity issues. Ample space will also be given to property law, contracts, corporate theory and other legal questions. The course is not very technical in its nature and is designed to provide all the needed background information for a full understanding of the economic issues covered

Alternative economic systems, with different public and private
institutions -> economic performance.
Law (on book and implemented),
2. EFFICIENCY EQUITY AND WELFARE

- economic surplus.
b) The new one developed by Pareto, Hicks, and Kaldor,
- Pareto efficiency, the Kaldor-Hicks compensation and the Scitovsky

- limitations on government's information and on its ability to set
tax and transfer structures
A note on "equity" and Economic Justice,
equality: of opportunity, egalitarianism, discrimination
Techniques of Redistribution
"Basic Needs Versus Distributional Weights in Social Cost-Benefit Analysis"

Externalities: The conventional analysis
Externalities in the law

Damages vs fines:
Fines vs Damage Payments
Coase vs Pigou-a summary:
4. RISK ADVERSION AND LAW ENFORCEMENT
The economics of risk aversion:
Von Neumann and Morgenstern utility.

Thinking about risk allocation.
Ex Ante, ex Post:
Bright lines: Rules v Standards.
"Impossible attempts": Should there be a penalty for attempting to kill

5. STRATEGIC BEHAVIOURS, RISK ALLOCATION AND INFORMATION
Strategic behavior: The problem, Examples:
Problems with insurance: Adverse Selection & Moral Hazard.
Insurance: A way of thinking through issues of risk and cost allocation
Property rules (allocation by consent of the owner) vs liability rules
(allocation by someone else taking, owner suing for damages). Why each makes
sense for some problems.
Application to product liability. Who is liable for damage done by exploding
How to decide whether or not the law should force Coke to "insure" its
customers against exploding Coke bottles. Why doesn't the law make these
calculations for ordinary insurance, deciding for you whether you are
insured or not?
Why not apply the same analysis to tort liability?
