Fertilizer demand is shown to increase with the depth of the off‐farm labor market. Controlling for exogenous weather risk, farmers use more fertilizer the lower the unemployment rate and the higher the share of nonagricultural work in total off‐farm labor. The results suggest that off‐farm labor markets and own‐farm production may be complementary in risky production environments, so that policies which promote the depth of the off‐farm labor market in low‐income areas may also bolster farm productivity.}, number={2}, journal={AMERICAN JOURNAL OF AGRICULTURAL ECONOMICS}, author={Lamb, RL}, year={2003}, month={May}, pages={359–371} }
 @article{lamb_2003, title={Inverse productivity: land quality, labor markets, and measurement error}, volume={71}, ISSN={["0304-3878"]}, DOI={10.1016/S0304-3878(02)00134-7}, abstractNote={This paper examines the role that land quality and imperfect markets play in generating the inverse productivity relationship in the International Crop Research Institute for the Semi Arid Tropics (ICRISAT) data. Differences in land quality largely explain the “Inverse Productivity” (IP) relationship in the random effects profit regression, but not in labor demand regressions. Controlling for labor and land market failures and differences in soil quality eliminates the IP relationship for male labor, but not female labor in the random effects estimates. The inverse relationship is much stronger in fixed effects than random effects estimates, suggesting that the farm size variable may be subject to measurement error, a view supported by the results of instrumental variables estimation.}, number={1}, journal={JOURNAL OF DEVELOPMENT ECONOMICS}, author={Lamb, RL}, year={2003}, month={Jun}, pages={71–95} }
 @article{lamb_2002, title={A market-forces policy for the new farm economy?}, volume={24}, ISBN={1058-7195}, DOI={10.1111/1467-9353.00081}, abstractNote={This paper first discusses the changes that are bringing about the New Farm Economy. A wave of consolidation has shifted agricultural production to larger, lower cost producers in almost all sectors of agriculture. At the same time, supply chains represent a new form of ownership and control that is replacing commodity markets as the preferred way to market farm output. Both consolidation and the development of supply chains offer the possibility of producing a greater variety of safer, cheaper food. The paper argues that farm policy, crafted for the agriculture of the 1930s, is no longer necessary to raise or stabilize farm incomes, and is largely ineffective anyway. Moreover, farm policy impedes the market forces driving innovation and efficiency in the farm economy. Letting market forces guide the evolution of the farm economy, unfettered by outdated government programs and unnecessary farm subsidies, is the best way to harness the benefits of the New Farm Economy. Getting rid of government subsidies and control will lead to dramatically fewer farmers in agriculture; a policy to deal explicitly with those who will leave agriculture is needed. A transition policy is described that focuses on helping reduce the number of farmers by offering a buyout to farm producers which subsidizes their exit from farming and prevents reentry.
