Job matching, family gap and fertility choice
(Te Herenga Waka—Victoria University of Wellington, 2012) Chang, Chia-Ying; Laing, Derek; Wang, Ping
This paper concentrates on the role of job matching frictions in influencing the interactions between fertility choice and wage offers and show that job market frictions are a crucial factor in wage differentials among female workers. The goals of this paper are to examine how the home-stay alternative and asymmetric market frictions influence this wage differential and whether the well documented negative correlation between fertility choice and female earnings still holds in the face of life-cycle choices. To address these questions, we develop a search-theoretic model that incorporates fertility and job decisions and assume that the workers with children face a lower job matching rate and a higher job quitting rate relative to the rates faced by the workers without children. As a result, we find that a wider wage differential is associated with more asymmetric market frictions and that the wage differential has a positive effect from output differential, a positive scale effect from the output of mothers and a negative effect from the utility from staying home. The wage differential is positively correlated with both fertility and home-stay rates and negatively correlated with market thickness and matching technology. Furthermore, by having both fertility and home-stay choices endogenously determined, we can show that a tighter market will enhance the fertility rate and the home-stay rate and a better job matching technology would not only increase the home-stay rate but decrease the fertility rate. In general equilibrium, the effects of both market tightness and the matching technology on the wage differential are indeterminate. These results indicate that the home-stay choice actually gives workers with children not only an alternative but also the power to negotiate higher wages. This shrinks the wage differential. Finally, the result that a higher fertility rate enlarges the wage differential also implies a negative relationship between the fertility rate and the earnings of workers with children. This result is consistent with standard empirical findings.

Power of personalized smoking cessation: A unified lifecycle framework for policy evaluation
(Te Herenga Waka—Victoria University of Wellington, 2018) Chen, Li-Shiun; Wang, Ping; Yao, Yao
Cigarette smoking leads to large healthcare and morbidity costs, and mortality losses, and smoking cessation plays a key role in reducing health risk and economic costs. While medical evidence suggests that some smokers are more likely to respond to medication treatment than others depending on genetic markers, it remains unexplored whether pharmacogenetic testing is cost-effective in treating potential quitters of smoking. We address this knowledge gap by developing a lifecycle model in which individuals make smoking, health investment and consumption-savings decisions. Depending on an individual’s genotype and demographics, smoking may bring enjoyment but deteriorates one’s health, and the dynamic evolution of health capital determines life expectancy. We incorporate various aspects of behavioral considerations that justify policy intervention. We calibrate this model to fit key economic and medical observations in the U.S. We then propose three smoking cessation policies, two with standard treatments and one personalized depending on genetic markers, all under the same program costs. We construct two unified measures of effectiveness and subsequently compute the cost-effectiveness ratio. We find that personalized treatment is the most cost-effective: for each dollar of program cost, it generates $4:59 value in effectiveness, which is 22 43% higher than those under standard treatments. The result is robust to several variations to the benchmark setting, including most importantly second-hand smoking, incomplete health knowledge, and bounded rationality.
