In this paper, we propose a framework to build prediction models from data streams which contain both labeled and unlabeled examples. We argue that due to the increasing data collection ability but limited resources for labeling, stream data collected at hand may only have a small number of...

Existing studies generally use ``aggregate'' temperature measures, such as mean temperature, degree-days, temperature bins, and piece-wise linear function within the growing season, to estimate the impact of global warming on crop yield. These temperature measures blend temperatures from...

The economic costs of trans-boundary pollution spillovers versus local effects is a necessary input in evaluating centralized versus decentralized environmental policies. Directly estimating these for air pollution is difficult because spillovers are high-frequency and vary with distance while...

We provide nationwide estimates of air pollution’s effect on short-run labor productivity for manufacturing firms in China from 1998 to 2007. An emerging literature estimates air pollution’s effects on labor productivity but only for small groups of workers of particular occupations or...

The authors propose a robust transformation linear mixed-effects model for longitudinal continuous proportional data when some of the subjects exhibit outlying trajectories over time. It becomes troublesome when including or excluding such subjects in the data analysis results in different...

Air transport Greenhouse Gas (GHG) emissions estimates differ greatly, depending on the calculation method employed. Among the IPCC, ICAO, DEFRA, and BrighterPlanet calculation methods, the largest estimate may be up to 4.5 times larger than the smallest. Such heterogeneity -- and ambiguity over...

We provide comprehensive estimates of air pollution’s effect on short-run labor productivity for manufacturing firms in China from 1998 to 2007. An emerging literature estimates air pollution’s effects on labor productivity but only for small groups of workers of particular occupations or...
