Abstract The polarization of the cosmic microwave background (CMB) can be used to search for parity-violating processes like that predicted by a Chern-Simons coupling light pseudoscalar field. Such an interaction rotates E modes into in observed CMB signal through effect known as birefringence. Even though isotropic birefringence confused with rotation produced miscalibration detectors' angles,...

Recent reviews of scientific work on subjective well-being (SWB) reveal disagreements in conceptualization, measurement, and explanation of the concept. We propose Social Production Function theory as a framework to resolve them. Social Production Function (SPF) theory integrates strengths of relevant psychological theories and economic consumer/household production theories, without their limi...

The impact of endogeneity and measurement error on the estimated effect of household economic resources on child height is demonstrated. These econometric problems contribute to uncertainty in the literature about the significance of income effects on child health and nutrition. Results are based on a household survey from Papua New Guinea, where repeated within-year observations on households ...
