Human parental effort and environmental risk.

Parental investment decisions depend on multiple factors, including the extent that parental care benefits offspring. Humans should show reduced parental effort in environments where parenting cannot improve offspring survival. Data from the standard cross-cultural sample are used to test this prediction. The results show that maternal care was inversely associated with famine and warfare, and ...

Ability Tracking, Parental Effort and Student Achievement∗

We develop and estimate an equilibrium model of ability tracking. A school allocates students into tracks based on their ability and then chooses trackspecific inputs to test score production. Parents choose parental effort in response. We estimate the model using data from the ECLS-K. We use the estimated model to quantify the effects of allowing ability tracking, making proficiency standards ...

Risk-based Pricing and Risk-reducing Effort: Does the Private Insurance Market Reduce Environmental Accidents?

This paper examines whether risk-based pricing promotes risk-reducing effort. Such mechanisms are common in private insurance markets, but are rarely incorporated in government assurance programs. We analyze accidental underground fuel tank leaks—a source of environmental damage to water supplies—over a fourteen-year period, using disaggregate (facility-level) data and policy variation in finan...

Ability Tracking, School and Parental Effort, and Student Achievement

We develop and estimate an equilibrium model of ability tracking. In the model, a school chooses how to allocate students into tracks based on their ability and chooses track-specific inputs. Parents choose parental effort in response. We estimate the model using data from the ECLS-K. We use the estimated model to first examine the effects of disallowing tracking on school and parental inputs a...

Clutch Size and Parental Effort in the Great Tit Parusmajor

We experimentally reduced clutch size of Great Tits Parus major to investigate the effects on parental care (including Daily Energy Expenditure, DEE, measured with doubly labelled water), and the relationship between DEE and the residual reproductive value. The length of a working day was not affected, but the nestling phase was 0.7 days (4%) shorter in experimental clutches. Males fed reduced ...
