Progress 10/01/16 to 09/30/21
Outputs Target Audience:Other researchers; policymakers involved in design of government risk management programs (e.g., crop insurance in the US). Changes/Problems:
Nothing Reported
What opportunities for training and professional development has the project provided?One doctoral dissertation testing measurement of welfare central to approach by Carly Trachtman nearly complete; training of another PhD student (Jedidiah Silver) in development of econometric approaches to estimation and testing. How have the results been disseminated to communities of interest?A variety of talks at conferences or seminars. Notably {``Relative Household Welfare from Relative Expenditures,'' Plenary address to STEG/CEPR Annual Conference, January 2021.} {``Farm-Households,'' Invited presentation to the Artificial Intelligence for Food Systems Institute, Berkeley, October 2020.} ? What do you plan to do during the next reporting period to accomplish the goals?
Nothing Reported
Impacts What was accomplished under these goals?
1) Major progress in theoretical description of problem, including method to distinguish between the effects of financial risks on production and the effects of distortions in input markets. 2) Work advanced on applications and data to use methods (data from US ARMS, Thailand, LSMS-ISA countries).

Progress 10/01/19 to 09/30/20
Outputs Target Audience:Other researchers and economists interested in risk in agriculture. Changes/Problems:
Nothing Reported
What opportunities for training and professional development has the project provided?1 PhD student involved in developing database of expenditures for US farm households; 1 PhD student involved in developing empirical methods for understanding the impact of risk on producer decisions 1 MA student involved in construction of large dataset on consumption expenditures, to be used to assess exposure to risk. How have the results been disseminated to communities of interest?Academic publications. What do you plan to do during the next reporting period to accomplish the goals?Pursuing work involving modeling and estimation of risk for US producers, as well as contrasting this risk with risk borne by farmers in low income countries.
Impacts What was accomplished under these goals?
Progress on Major goals (1) & (2): Sometimes we don't /know/ the environment in which agricultural producers are operating, and in particular it's difficult to know what financial constraints producers face. In a major paper with Zhimin Li I work out ways to infer /both/ how much risk-sharing there is /and/ whether the financial regime under which producers are operating is characterized by imperfections related to private information.

Outputs Target Audience:Other researchers and economists interested in risk in agriculture. Changes/Problems:
Nothing Reported
What opportunities for training and professional development has the project provided?Training for six undergraduates and three PhD students. How have the results been disseminated to communities of interest?Journal publications, new course at UC Berkeley (EEP153) What do you plan to do during the next reporting period to accomplish the goals?Continue work on measurement of marginal utilities of expenditure, with new focus on inferring individual welfare from household-level expenditures.
Impacts What was accomplished under these goals?
Progress made on measuring marginal utility of expenditures for US Farmhouseholds; variation in this closely related to risk.

What opportunities for training and professional development has the project provided?Graduate student Elliott Collins implemented methods for measuring welfare in his 2017 dissertation. How have the results been disseminated to communities of interest?Publications in economic journals; workshops; seminars. What do you plan to do during the next reporting period to accomplish the goals?Plan to develop empirical methods, apply to populations including US farmers.
Impacts What was accomplished under these goals?
Major work on the theory of how to best measure household welfare in a dynamic setting with limited data on expenditures. See publications on Frisch demand systems.
