Combining Proxies and Narrative Sign Restrictions: Revisiting the Effects of Technology Shocks

open access: yesJournal of Applied Econometrics, EarlyView.
ABSTRACT This paper proposes a novel integration of the proxy structural vector autoregression approach with narrative sign restrictions to identify multiple shocks with multiple instrumental variables. We show that this combination leads to informative inferences on shock effects through both analytical demonstrations and Monte Carlo simulations ...

A Nordhaus–Gaddum Problem for the Spectral Gap of a Graph

open access: yesJournal of Graph Theory, EarlyView.
ABSTRACT Let G $G$ be a graph on n $n$ vertices, with complement G¯ $\bar{G}$. The spectral gap of the transition probability matrix of a random walk on G $G$ is used to estimate how fast the random walk becomes stationary. We prove that the larger spectral gap of G $G$ and G¯ $\bar{G}$ is Ω(1∕n) ${\rm{\Omega }}(1\unicode{x02215}n)$.
