Determinants of smallholder farmers' participation in banana markets in Central Africa: the role of transaction costs

A bivariate probit model was employed to jointly and separately estimate banana market participation decisions of buying and selling households in Rwanda and Burundi using household survey data. Selectivity bias was corrected for estimating the transacted volumes using Heckman's procedure. The results showed that transaction cost‐related factors such as geographical location of households, market information sources, and travel time to the nearest urban center influence market participation. Non‐price‐related factors such as security of land tenure, labor availability, off‐farm income, gender of the household head, and years of farming experience had a significant influence on the transacted volumes. Output prices had a significant correlation with sales volume, indicating price incentives increased supply by sellers. Generally, the findings suggest that policies aimed at investments in rural road infrastructure, market information systems, collective marketing, and value addition of banana products may provide a potential avenue for mitigating transaction costs and enhancing market participation and production of marketed surplus by rural households.     

When economics harmonized mathematics in Japan: a history of stability analysis

This article discusses how economics was mathematized by Japanese theoretical economists with the cooperation of Japanese mathematicians before 1950. Mathematicians played the leading part in assimilating European scientific ideas and providing an internationally oriented attitude in Japan from the mid nineteenth century. They began to publish many updated textbooks in Japanese from around 1930 on. In the 1940s, Japanese mathematical economists were intensively studying the so-called stability problem, thereby mathematizing economics more rapidly than ever before. Their research activity will give us an interesting example of a process of organizing economic knowledge by introducing more mathematics into the economics literature.     

Job Satisfaction,Work Time,and Well-Being Among Married Women in Japan

Abstract

This paper examines the relationship between paid work time and other time use of working married women with children in Japan and two aspects of well-being: job satisfaction and stress. The study demonstrates that rather than the amount of daily paid work time, both the gap between actual and desired work time and the intrinsic utility derived from paid work as an activity appear to be the key time-related variables affecting Japanese women's job satisfaction. The paper also shows that paid work time has multiple spillover effects on stress. It discusses the tradeoffs that married women with children in Japan make to stay in employment and the consequences for employer strategies and public policy.
