Abstract

We used a new analytical approach to quantitatively investigate the contribution of structural variables in the sericulture industry to changes in cocoon yield in Japan during the period 1915-1996. Variance decomposition analysis revealed that improvements in rearing technology and an increase in the number of cocoon producers before world War II, along with increases in productivity and in the area under mulberry cultivation after the War, were mainly responsible for increased cocoon production. More complex mechanisms underlay the decreases in cocoon production that varied across regions, particularly after the War.
