A Unified Approach to Estimating Production Functions: Proxy Variables and Dynamic Panel Data

More specifically, we analyze the asymptotic properties of a test we developed in previous work in a pure‐jump setting.

open access: yesMind &Language, EarlyView.
An influential account of moral judgment suggests there are two distinctive domains: that of conventional wrongs (a breach of social norms that can be changed/“modified” by an authority figure) and moral wrongs (that are viewed as breaching “natural law” and cannot be “modified”).
