Lecture 8 - Game Theory I: Foundations

Static games of complete information: dominant strategies, dominated strategies, best responses and Nash Equilibrium in pure and mix strategies
Dynamic games with complete and perfect information: Sequentially Rational Equilibrium (SRE) and solution by backward induction 


Lectures 6 and 7 - General Equilibrium, Social Welfare and Externalities

21 Outubro 2026, 18:00 • Camila Steffens

We covered general equilibrium in an economy with exchange, then the two welfare theorems and social welfare (aggregation challenges). 

Next, we covered general equilibrium in an economy with production, followed by introduction to market failures.
Finally, we covered externality, with an application about carbon tax from Golosov et al. (Econometrica, 2014): Optimal taxes on fossil fuel in general equilibrium. 




Lecture 5: Partial Equilibrium

14 Outubro 2026, 18:00 • Camila Steffens

We covered the competitive equilibrium in the short and long run, plus partial equilibrium and welfare. 

Extension to midterm question 1: computing the compensating variation (willingness to pay) for a food subsidy and compare to cash transfer. 
Application: Marion & Muehlegger (2011), Fuel Tax Incidence and Supply Conditions.
