In the linear response regime close to equilibrium, the fluctuation-dissipation theorem
relates linear transport coefficients via the well-known Green–Kubo or Einstein relation. The …

I establish the equivalence between the two-way fixed effects (TWFE) estimator and an
estimator obtained from a pooled ordinary least squares regression that includes unit …

We study the conditions under which it is possible to estimate regression quantiles by
estimating conditional means. The advantage of this approach is that it allows the use of …
