Intersectoral labor migration and agriculture in the United States and Japan

Ramsey, AF; Sonoda, T; Ko, MKY

AGRICULTURAL ECONOMICS Vol. 54 ( 3 ) page： 364 - 381 2023.5

Publisher：Agricultural Economics (United Kingdom)

In spite of important differences in their agricultural sectors, the past century has seen a significant decline in the number of people employed in agriculture in the U.S. and Japan. Economic models of intersectoral labor migration focus on expected return differentials as the primary cause of migration from one sector to another. Empirical applications typically assume that migration occurs as soon as the return differential exceeds Marshallian migration costs, but recent work has focused on embedding the migration decision in a real options framework. Structural and institutional elements can also affect the speed at which the share of agricultural labor declines. We consider the factors influencing intersectoral labor migration in the U.S. and Japan using aggregate migration equations and several definitions of agricultural labor and return differentials. We show that real options, although relevant at the household level, have limited implications for sector-level empirical models. Our estimates are inconclusive regarding the importance of the Marshallian trigger in the migration decision, with heterogeneity across the two countries and labor definitions. We argue that this heterogeneity in the wage and migration relationship is driven by differences in the structures of the agricultural sectors.

WHY DO HOUSEHOLD HEADS IN RURAL CHINA NOT WORK MORE IN THE MARKET? Invited Reviewed

Tadashi Sonoda

SINGAPORE ECONOMIC REVIEW Vol. 59 ( 1 ) 2014.3

Language：English Publishing type：Research paper (scientific journal) Publisher：WORLD SCIENTIFIC PUBL CO PTE LTD

This study estimates a modified disequilibrium model to ascertain the relative importance of reasons why household heads in rural China do not work more in the market. Household heads in the Central and Western regions do not so because they have fewer young children, live with their grown-up children or must help their family members with economic crops or livestock production. Household heads in the Eastern region do not work extra because nearly 40% of them are constrained in the labor market. This constraint seems to come from traditional economic structure which demands more temporary workers than permanent ones.

A system comparison approach to distinguish two nonseparable and nonnested agricultural household models

Sonoda, T

AMERICAN JOURNAL OF AGRICULTURAL ECONOMICS Vol. 90 ( 2 ) page： 509 - 523 2008.5

Publisher：American Journal of Agricultural Economics

This study distinguishes two nonseparable agricultural household models for a self-employed farm household. One assumes heterogeneity of farm and nonfarm labor and a competitive market for nonfarm labor. The other assumes homogeneity of the two types of labor and a restricted market for nonfarm labor. We compare demand systems that are derived from them, which have different dependent variables and different numbers of equations. We apply a Cox-type test to compare these complicated nonnested systems. Results show clearly that the former is better for Japanese rice-farming households. Comparison of price elasticities for those models verifies the importance of that test. © 2008 American Agricultural Economics Association.

An empirical method for a model of self-employed households

Sonoda T.

Family and Consumer Sciences Research Journal Vol. 30 ( 4 ) page： 540 - 553 2002.6

Language：Japanese Publisher：Family and Consumer Sciences Research Journal

This article presents an empirical method for a simple model of self-employed households. In this model, the “internal wage” plays a crucial role of equilibrating the demand and supply of family labor within the household. By paying special attention to this wage, all structural parameters of the model can be estimated and are used to verify the seemingly anomalous characteristics of self- employed households: They earn less (per hour or week) and work longer than salary and wage workers and their own price elasticity of output supply is small or negative. © 2002 American Association of Family and Consumer Sciences.
