Absent theoretical guidance, empiricists have been forced to rely upon numerical comparative statics from constant tax rate models in formulating testable implications of tradeoff theory in the context of natural experiments. We fill the theoretical void by solving in closed-form a dynamic...

Causal evidence from random assignment has been labeled "the most credible." We argue itis generally incomplete in finance/economics, omitting central parts of the true empirical causalchain. Random assignment, in eliminating self-selection, simultaneously precludes signaling viatreatment...

We incorporate structural modellers into the economy they model. Using the traditional moment-matching method, they ignore policy feedback and estimate parameters using a structural model that treats policy changes as zero probability (or exogenous) "counterfactuals." Estimation bias occurs...
