Effectiveness of mobile application for menstrual management of working women in Japan: randomized controlled trial and medical economic evaluation

Abstract

Aims: Hormonal imbalances can affect a woman’s physical and mental condition, impacting her daily life and productivity. A mobile application, “Karada-no-kimochi”, predicts the menstrual cycle based on recorded data, and provides the information regarding menstruation. This study investigates the effectiveness of the application from health condition and labor productivity loss perspectives, and evaluates its cost-effectiveness for employed women in Japan.

Materials and methods: A randomized controlled trial (RCT) was performed to compare the use of the application and non-intervention in female workers (20–45 years) based on an online survey. A discrete-event model based on the RCT data, published literature, and claims data was used for the cost-effectiveness analysis.

Results: The intervention and non-intervention groups comprised 612 and 914 women, respectively. In the intervention group, the incidences of depression (0.16%) and dysmenorrhea (0.33%) were significantly lower than those of the non-intervention group (0.77% and 1.31%, respectively) in the third month. While labor productivity and absenteeism varied, presenteeism showed almost no change across groups. The quality-adjusted life year in the intervention group was 6.84 (0.07 higher than that in the non-intervention group). By analyzing medical expenses and making assumptions regarding productivity, we estimated that the aggregate of medical expenses, productivity loss, and application fee for the intervention group could be lower than that of the non-intervention group by over JPY 130,000 (USD 1,170, as of December 2017) per individual.

Limitations: The subjects included were willing or relatively willing to use the application. Because all outcomes were based on online surveys, the results depended on the objectivity and preciseness of the reports provided by users, and those with severe symptoms might not provide reports.

Conclusions: The results suggest that using the application is cost-effective and might reduce the incidence of dysmenorrhea and depression.

Equality of interest rates revisited: the multi‐country evidence

One influential aspect of international integration of financial markets is the possibility of reducing divergences between domestic interest rates and foreign interest rates or increasing the degree to which yields in different financial markets move together over time. In this study, we investigate the convergence of the real interest rates using the Kalman filter. Applying the modified Hall et al. () approach, we model the risk premium and convergence of real interest rates using the time‐varying parameter estimation techniques. We present evidence of risk premium and convergence for two blocks of countries—The Asian‐Pacific countries including the US, Japan, Taiwan and South Korea and the US‐European group including France, the UK, Germany and the US.

Human Capital, Heterogeneity and Estimated Degrees of Intergenerational Mobility

We study the parental investment model of intergenerational mobility, where heterogeneity in 'innate' earnings ability and parents' altruism rate is explicitly modelled. We show that heterogeneity increases the difficulty of detecting the existence of borrowing constrained families. Conversely, the presence of heterogeneity means that economic and linear statistical models of inheritance generate similar intergenerational data on consumption and earnings. We also suggest that nay cross-country differences in intergenerational earnings mobility are more readily interpreted according to the heterogeneity of inherited ability, rather than optimal family responses to country-specific institutions for accumulating human capital.     

加拿大中小企业的融资支持

一、加拿大中小企业融资来源及现状 加拿大对小企业并没有一致的定义，不同的机构根据它们自己的需要对小企业下定义，比如，对于“小”的定义，加拿大银行家协会为贷款低于25万美元的企业，而出口发展协会则定义出口销售低于100万美元的企业，工业部则基于雇用者的人数，如生产企业的雇用人数少于100则称为小企业，而服务行业的区分点则是50人。当人数达到500，则称为中型企业。加拿大中小企业资金来源主要有两个方面。
