Home Production, Market Production and the Gender Wage Gap: Incentives and Expectations

The purpose of this paper is to study the joint determination of gender differentials in labor market outcomes and in the household division of labor. Specifically, we explore the hypothesis that incentive problems in the labor market amplify differences in earnings due to gender differentials in home hours. In turn, earnings differentials reinforce the division of labor within the household, leading to a potentially self-fulfilling feedback mechanism. The workings of the labor market are key in our story. The main assumptions are that the utility cost of work effort is increasing in home hours, and that higher effort should correspond to higher incentive pay. Household decisions are Pareto efficient, leading to a negative correlation between relative home hours and earnings across spouses. We use the Census and the PSID to study these predictions and find that they are supported by the data.

Gender roles and technological progress

Until the early decades of the 20th century, women spent more than 60% of their prime-age years either pregnant or nursing. Since then, the introduction of infant formula reduced women's comparative advantage in infant care, by providing an effective breast milk substitute. In addition, improved medical knowledge and obstetric practices reduced the time cost associated with women's reproductive role. We explore the hypothesis that these developments enabled married women to increase their participation in the labor force, thus providing the incentive to invest in market skills, which in turn reduced their earnings differential with respect to men. We document these changes and develop a quantitative model that aims to capture their impact. Our results suggest that progress in medical technologies related to motherhood was essential to generate a significant rise in the participation of married women between 1920 and 1950, in particular those with young children

Gender Roles and Medical Progress

The entry of married women into the labor force is one of the most notable economic phenomena of the twentieth century. We argue that medical progress played a critical role in this process. Improved maternal health alleviated the adverse effects of pregnancy and childbirth on women's ability to work, while the introduction of infant formula reduced mothers' comparative advantage in infant feeding. We construct economic measures of these two dimensions of medical progress and develop a quantitative model that aims to capture their impact. Our results suggests that these advances, by enabling women to reconcile work and motherhood, were essential for the rise in married women's participation and the evolution of their economic role.

Women in the workplace: 50 years of change

Decades of progress have seen greater opportunities for women in the workplace, but sizeable gender gaps remain in most indicators of economic achievement. Stefania Albanesi, Claudia Olivetti, and Barbara Petrongolo review the effect of family policies on women’s careers and set out the challenges to come

Families, labor markets and policy

Using comparable data for 24 countries since the 1970s, we document gender convergence in schooling, employment and earnings, marriage delay and the accompanying decline in fertility, and the large remaining gaps in labor market outcomes, especially among parents. A model of time allocation illustrates how the specialization of spouses in home or market production responds to preferences, comparative advantages and public policies. We draw lessons from existing evidence on the impacts of family policies on women's careers and children's wellbeing. There is to date little or no evidence of beneficial effects of longer parental leave (or fathers' quotas) on maternal participation and earnings. In most cases longer leave delays mothers' return to work, without long-lasting consequences on their careers. More generous childcare funding instead encourages female participation whenever subsidized childcare replaces maternal childcare. Impacts on child development depend on counterfactual childcare arrangements and tend to be more beneficial for disadvantaged households. In-work benefits targeted to low-earners have clear positive impacts on lone mothers' employment and negligible impacts on other groups. While most of this literature takes policy as exogenous, political economy aspects of policy adoption help understand the interplay between societal changes, family policies and gender equality

Surgery of colorectal cancer lung metastases: analysis of survival, recurrence and re-surgery

BACKGROUND: Surgery is considered an effective therapeutic option for patients with lung metastasis (MTS) of colorectal cancer (CRC). The purpose of the study was to evaluate efficacy and feasibility of lung metastasectomy in CRC patients and to explore factors of prognostic relevance. METHODS: This is a retrospective study of patients operated for lung MTS of CRC from 2004 to 2012 in a single Institution. Overall survival (OS) was the primary endpoint. Secondary endpoints were progression free survival (PFS) in resection status R0 and OS in in patients submitted to re-resections. In order to evaluate prognostic factors, a multivariable Cox proportional hazard model was performed. RESULTS: One-hundred eighty-eight consecutive patients were included in the final analysis. The median follow-up (FU) was 45 months. The 5-year OS and PFS were 53% (95% CI: 44–60%) and 33% (95% CI: 25–42%), respectively. Two- and 5-year survival after re-resection were 79% (95% CI: 63–89%) and 49% (95% CI: 31–65%), respectively. Multivariate adjusted analysis showed that primary CRC pathological TNM stages (P=0.019), number of resected MTS ≥5 (P=0.009) and lymph nodal involvement (P<0.0001) are independent predictors of poor prognosis. CONCLUSIONS: Patients operated and re-operated for lung MTS from CRC cancers showed encouraging survival rates. Our results indicated that primary CRC stage, number of MTS and lymph nodal involvement are strong predictive factors. Prognosis after surgery remained comforting up to four resected MTS. Adjuvant chemotherapy seems to have a benefit on survival in patients affected by multiple metastases. Finally, according to the high rate of unidentified lymph node involvement in pre-operative setting, lymph node sampling should be advisable for a correct staging
