Measurement uncertainty matters: ecological management using POMDPs
Over the past 30 years, researchers have used various approximations to address the impact of measurement uncertainty on optimal management policy. This literature has consistently suggested the counter-intuitive proposition that increasing harvest levels in the presence of measurement error is often optimal. Here, we use state-of-the art algorithms for Partially Observed Markov Decision Proces...

متن کاملPhysical fitness in children with developmental coordination disorder: measurement matters.
Children with Developmental Coordination Disorder (DCD) experience considerable difficulties coordinating and controlling their body movements during functional motor tasks. Thus, it is not surprising that children with DCD do not perform well on tests of physical fitness. The aim of this study was to determine whether deficits in motor coordination influence the ability of children with DCD to...
متن کاملMeasurement matters – Input price proxies and bank efficiency in Germany
Most bank efficiency studies that use stochastic frontier analysis (SFA) employ each bank’s own implicit input price when estimating efficient frontiers. But the theoretical foundation of most studies is a cost minimisation and/ or profit maximisation problem assuming perfect input markets. At the very least, traditional input price proxies therefore contain substantial measurement error. In th...
متن کاملIndicators of Product Sophistication and Factor Intensities: Measurement Matters
The widely used PRODY indicator by Hausmann, Hwang and Rodrik (2007) [What you Export Matters; Journal of Economic Growth: 12, 1–25] allows the calculation of product sophistication and factor intensities at high levels of disaggregation. In this paper I deal with its measurement, its conceptional limitations, its sensitivity to subjective decision making, its alternatives, and how to reap the ...
