§ Monotone
Pragmatics, 2015
I
discuss how the meaning of language can depend on contexts, i.e.
pragmatics. Specifically, in a version of Crawford and Sobel (1982) in
which the sender and the receiver share common preferences and with finite
messages, I derive a monotone comparative statics result on how optimal
cut-offs (efficient language) change with prior beliefs (contexts), called
monotone pragmatics. Monotone pragmatics explains, for example, why Eskimo
languages might have an unusually
large number of words for snow. I also discuss implications for mechanism
design with limited communication.

§ Informational
Inertia, with Lones
Smith, 10/2014
We
fully characterize a basic property, called informational inertia, of
experiments with binary states: the posterior belief, after observing a
lumpy posterior event, increases with the prior belief. The lack of
informational inertia is the reason that information cascades exist in
observational learning. We show that informational inertia illuminates
statistical or intrinsic discrimination as well as decision making by
committees.
