Certainty equivalence and model uncertainty [PDF]
Simon’s and Theil’s certainty equivalence property justifies a convenient algorithm for solving dynamic programming problems with quadratic objectives and linear transition laws: first, optimize under perfect foresight, then substitute optimal forecasts ...

Wildlife Biology, EarlyView.Many bird species are monitored using auditory point count surveys during the breeding season. Autonomous recording units (ARUs) can be used to better understand the daily and seasonal timing of when a species is vocalizing, which can help align surveys with the time period when the maximum number of individuals are present. We used ARUs to improve our

Monetary policy in a small open economy with a preference for robustness [PDF]
We use robust control techniques to study the effects of model uncertainty on monetary policy in an estimated, semi-structural, small-open-economy model of the U.K.

Should you use data integration for your distribution model?
Journal of Animal Ecology, EarlyView.This paper explores cases where data integration (the joint modelling of two or more observational datasets) is useful for species distribution models, and also highlights cases where it's actually not useful. This provides the first concrete guidance for deciding whether or not data integration is worth your time.

Detecting model misspecification in cosmology with scale-dependent normalizing flows
Machine Learning: Science and TechnologyCurrent and upcoming cosmological surveys will produce unprecedented amounts of high-dimensional data, which require complex high-fidelity forward simulations to accurately model both physical processes and systematic effects which describe the data ...

Economic Record, EarlyView.Humanitarian migrants are among the most vulnerable migrant groups, often facing significant integration challenges, particularly language barriers. In response, many developed countries have introduced language programs to support their settlement. This study uses an event study (staggered difference‐in‐differences) approach and data from Australia's ...

Mankiw's Puzzle on Consumer Durables: A Misspecification [PDF]
Mankiw (1982) shows that consumer durables expenditures should follow a linear ARMA(1,1) process, but the data analyzed supports an AR(1) process instead; thus, a puzzle.

Health Services Research, EarlyView.ABSTRACT Objective To determine the effectiveness and cost‐effectiveness of multi‐gene panel sequencing compared to single‐gene KRAS testing for metastatic colorectal cancer (mCRC). Study Setting and Design British Columbia, Canada (BC) is a provincial single‐payer public healthcare system, and it was the first province to publicly reimburse multi‐gene

Modeling Demand for Outdoor Recreation Settings with Choice Based Data Accounting for Exogenous and Endogenous Stratification [PDF]
Estimating regional demand models by pooling different samples without correcting for such differences causes model misspecification as each sample belongs to a different population.

Journal of Agricultural Economics, EarlyView.ABSTRACT We investigate the impact of air quality regulations targeting fine particulate matter (PM2.5) on farmland values in corn and soybean producing counties in the United States over the period 1997–2022. Using self‐reported farmland value data from the Agricultural Census and county‐level pollution classifications provided by the Environmental ...
