Recent years have seen a surge of applied work using bunching approaches, a
development that is closely linked to the increased availability of administrative data. These …

We develop a framework for nonparametrically identifying optimization frictions and
structural elasticities using notches—discontinuities in the choice sets of agents—introduced …

Energy-efficient technologies offer considerable promise for reducing the financial costs and
environmental damages associated with energy use, but it has long been observed that …

We review what is known about the economic efficiency of fuel taxes relative to efficiency
standards aimed at mitigating environmental externalities from cars. We present a simplified …

This paper argues that it will often be rational for consumers to pay limited attention to
energy efficiency when choosing among energy-consuming durable goods like automobiles …

This paper provides novel estimates of the interest rate elasticity of mortgage demand by
measuring the degree of bunching in response to a discrete jump in interest rates at the …

Using discontinuities in housing transaction taxes in New York and New Jersey we find
robust price bunching. Incidence for transactions local to the notch falls on sellers, with no …

We study attribute-based regulations, under which regulatory compliance of a firm, product,
or individual depends on a secondary attribute that is not the intended target of the …

Economists endorse taxes as a cost-effective means of reducing pollution. But policy makers
raise concerns about their regressivity, or disproportional burden on poorer families …

I exploit a major, unanticipated reform of the California teachers' pension to provide quasi-
experimental evidence on the link between pension features and retirement timing. Using …
