Social Status, Inequality, and Redistribution

International Economic Review, EarlyView.
ABSTRACT We explore implications of social status concerns for redistribution, income inequality, and growth in a political economy framework. Salience of such concerns leads to a propagation mechanism, whereby initial income inequality and reduced willingness to redistribute income reinforce each other, potentially giving rise to multiple steady ...

The Causal Effect of Parents' Education on Children's Earnings

International Economic Review, EarlyView.
ABSTRACT We develop and estimate a model of endogenous schooling and earnings to isolate the causal effect of parents' education on children's outcomes. Identification uses earnings differences among children with equal schooling whose parents have different schooling.

A Quantile Model of Firm Investment

International Economic Review, EarlyView.
ABSTRACT Are firms risk averse? We propose a dynamic model of firm investment under uncertainty that captures firms' risk attitudes through quantile preferences. The firm maximizes its present value, defined as current profits and investment plus the discounted value of the τ$\tau$‐quantile of its value next period.

Genetic Determination of Maternal Behaviour in Pigs

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT In sows, maternal behaviour is a commercially important trait which affects sow and piglet welfare and the quality and safety of human‐animal interactions, especially if free farrowing of sows without crates is in place. The aim of this study was to evaluate maternal behaviour and to estimate its quantitative genetic parameters in Swiss ...

Field Attraction of Natural Enemies to Methyl Salicylate Differs Between Annual and Perennial Cropping Systems

Journal of Applied Entomology, EarlyView.
ABSTRACT Methyl salicylate (MeSA) is an herbivore‐induced plant volatile (HIPV) known to attract natural enemies of herbivores; however, its effectiveness as a semiochemical across diverse cropping systems and broad geographic regions remains unclear. In this 2‐year field study, we sampled natural enemies using MeSA‐baited and unbaited (control) yellow

Freshwater hydrology emerges as the strongest predictor of phenological variability in a Southeast Alaska steelhead trout (Oncorhynchus mykiss) population

Journal of Fish Biology, EarlyView.
Abstract Phenological variation, such as the migration trends of salmonids, may provide resilience in changing environmental scenarios, influencing individual survival and population productivity. Phenological shifts may be particularly consequential for anadromous species that rely on seasonal cues for migration between freshwater and marine habitats ...

Bayesian analysis of a generalized lognormal distribution

Many data arising in reliability engineering can be modeled by a lognormal distribution. Empirical evidences from many sources support this argument. However, sometimes the lognormal distribution does not completely satisfy the fitting expectations in ...
