The Policy Research Working Paper Series disseminates the findings of work in progress to encourage the exchange of ideas about development issues. An objective of the series is to get the findings out quickly, even if the presentations are less than fully polished. The papers carry the names of the authors and should be cited accordingly. The findings, interpretations, and conclusions expressed in this paper are entirely those of the authors. They do not necessarily represent the views of the International Bank for Reconstruction and Development/World Bank and its affiliated organizations, or those of the Executive Directors of the World Bank or the governments they represent.

Why do farm households inefficiently allocate resources across the plots they cultivate? We explore how these production inefficiencies relate to consumption decisions and information sharing within the household. In a lab-in-the-field experiment, male producers allocate too few inputs to their wife's plot, failing to maximize household aggregate profits. They do transfer more inputs when the returns from that plot are higher. Experimental manipulation of information on these returns triggers heterogenous responses across households. We provide a theoretical framework that rationalizes these findings and further leads to sharp predictions. Joint contribution to a household public good compels spouses to make efficient production decisions. Only households who are in a separate-sphere regime experience inefficiency in farm production and are unable to effectively communicate on returns to avoid extra losses. Consistent with this framework, when we experimentally offer an ex post information verification mechanism, additional losses due to information asymmetries are prevented.
