Taxes and Market Power: A Principal Components Approach
Andrea Galeotti, Benjamin Golub, Sanjeev Goyal +2
Suppliers of differentiated goods make simultaneous pricing decisions, which are strategically linked. Because of market power, the equilibrium is inefficient. We study how a polic…
Homomorphisms to of automorphism groups of zero entropy shifts
Omer Tamuz
We show that the automorphism group of every zero entropy infinite shift admits a "drift" homomorphism to that maps the shift map to 1. This homomorphism arises as…
Information Cascades and Social Learning
Sushil Bikhchandani, David Hirshleifer, Omer Tamuz +1
We review the theory of information cascades and social learning. Our goal is to describe in a relatively integrated and accessible way the more important themes, insights and appl…
Monotone additive statistics
Xiaosheng Mu, Luciano Pomatto, Philipp Strack +1
The expectation is an example of a descriptive statistic that is monotone with respect to stochastic dominance, and additive for sums of independent random variables. We provide a…
