Energy intake and productivity of Guatemalan sugarcane cutters: An empirical test of the efficiency wage hypothesis part II

This paper examines additional evidence of an empirical test of the productivity-consumption relation of the efficiency wage hypothesis. A cross-sectional analysis showed sharply diminishing productivity returns to higher levels of daily energy intake of Guatemalan sugarcane cutters. No positive and consistent energy supplementation effect on the daily supply of work units could be demonstrated in a time-series analysis. Energy supplementation did not have a delayed impact on worker productivity. It is concluded that increased energy availability may not necessarily result in increased productivity of rural workers who are moderately energy deficient.
