Urban Public Works in Spatial Equilibrium: Experimental Evidence from Ethiopia
This paper evaluates a large urban public works program randomly rolled out across neighborhoods of Addis Ababa, Ethiopia. We find the program increased public employment and reduced private labor supply among beneficiaries ... -
Bayesian mixed-frequency quantile vector autoregression: Eliciting tail risks of monthly US GDP
(2023-12-01)Timely characterizations of risks in economic and financial systems play an essential role in both economic policy and private sector decisions. However, the informational content of low-frequency variables and the results ... -
Empirical study of graph spectra and their limitations
(2023)We examine the sensitivity of community-structured graph spectra to graph size, block size and inter-block edge probability. We use the Planted Partition Model because of its transparency. While this generative model may ... -
Quantum Kaluza-Klein theory with M <inf>2</inf>(ℂ)
(Springer Nature, 2023-09-01)Following steps analogous to classical Kaluza-Klein theory, we solve for the quantum Riemannian geometry on C∞(M) ⊗ M 2(ℂ) in terms of classical Riemannian geometry on a smooth manifold M , a finite quantum geometry on the ... -
Elementary Intracellular Ca Signals approximated as a Transition of Release Channel System from a Metastable State
(American Institute of Physics, 2023-09-22)Cardiac muscle contraction is initiated by an elementary Ca signal (called Ca spark) which is achieved by collective action of Ca release channels in a cluster. The mechanism of this synchronization remains uncertain. We ... -
A note on the marginal instability rates of two-dimensional linear cocycles
(Taylor & Francis, 2023)A theorem of Guglielmi and Zennaro implies that if the uniform norm growth of a locally constant GL2(R) -cocycle on the full shift is not exponential, then it must be either bounded or linear, with no other possibilities ... -
An irreducible linear switching system whose unique Barabanov norm is not strictly convex
(Society for Industrial and Applied Mathematics, 2023)We construct a marginally stable linear switching system in continuous time, in four dimensions, and with three switching states, which is exponentially stable with respect to constant switching laws and which has a unique ... -
Cosmology with the Laser Interferometer Space Antenna
(Springer Nature, 2023-12-01)The Laser Interferometer Space Antenna (LISA) has two scientific objectives of cosmological focus: to probe the expansion rate of the universe, and to understand stochastic gravitational-wave backgrounds and their implications ... -
Quantifying the uncertainty of partitions for infinite mixture models
(Elsevier, 2023)Bayesian clustering models, such as Dirichlet process mixture models (DPMMs), are sophisticated flexible models. They induce a posterior distribution on the set of all partitions of a set of observations. Analysing this ... -
Neuroscience Needs Network Science.
(The Society for Neuroscience, 2023-08-23)The brain is a complex system comprising a myriad of interacting neurons, posing significant challenges in understanding its structure, function, and dynamics. Network science has emerged as a powerful tool for studying ... -
