Nonlinear pricing is prevalent in industries such as health care, public utilities, and telecommunications. However, nonlinear pricing in these sectors causes bias when estimating elasticities for welfare analysis or policy changes. This paper develops a local elasticity estimation method that...

We consider statistical estimation of superhedging prices using historical stock returns in a frictionless market with d traded assets. We introduce a plugin estimator based on empirical measures and show it is consistent but lacks suitable robustness. To address this we propose novel estimators...

We propose a price-setting model which helps reconcile microeconomic evidence of relatively frequent and large price changes with persistent real effects of monetary shocks. In our model, both price adjustments and the gathering of some types of information are costly, requiring the payment of a...
