1- Adaptation to Climate Change in the Presence of Crop Insurance: The Case of US Farmers (job market paper)

Federal Crop Insurance is the largest protective program of the government of Unites States for the farmers. It changes volatility of returns by providing a minimum predictable income for farmers. This paper studies whether having a reliable insurer of last resort, the US government, creates opportunities for moral hazard of farmers in their crop choices.

Literature Review of Federal Crop Insurance

1- Understanding Crop Insurance

Section 2 of Chapter 3 in "Rate Methodology Handbook Actual Production History (APH)" (2009) is a great resource for understanding crop insurance and theories behind its pricing. Pages 205- 210 in chapter 12 of  Gardner and Kramer (1986) covers all alternatives proposed to improve the Federal Crop Insurance program up to the point of publication.

2- Policy Shocks

Table A-1 of Appendix to the Rosch (2021) paper, "Federal Crop Insurance: A Premier" provides an overview for the selected legislation that have affected the Federal Crop Insurance program. Other policy shocks are as following:

• 1947 Amendments

The FCIC reduced its operations from 2500 to 375 counties in 1947 (Gardner and Kramer, 1986, page 199). 

• Experimental program in 1948 for dry edible beans in four widely separated counties with different types of farming.

 Gardner and Kramer, 1986, page 199

• Experimental program in 1948  of multiple crop contract, indemnities based on their combined coverage

 Gardner and Kramer, 1986, page 199

• Acreage Reduction Program (1950 - 1996)

1- Yu, Smith and Sumner (2017) used this policy for the sensitivity analysis. 

• Removal of fourteen counties from FCIP in 1956

Beginning in 1956, FCIP announced insurance would no longer be sold in fourteen counties in Colorado, New Mexico, and Texas. These were considered high risk farming areas not suitable for insurance, because total indemnities had substantially exceed total premiums. If insurance had not been sold in these counties since 1948, the national program would have experiences a surplus of premiums over indemnities, rather than a deficit (Gardner and Kramer, 1986, page 200).

• Soil Bank Program (1955-1973)

• Establishment of Disaster Payments Program through The Agriculture and Consumer Protection Act of 1973, and The Rice Production Act of 1975.

Government started payments for prevented planting and payments for abnormally-low yields for producers of selected crops (Gardner and Kramer, 1986, page 201).

• Federal Crop Insurance Act of 1980 

It expanded the crop insurance program to become the major form of disaster protection in the United States, authorized expansion of the program to all counties with significant agriculture, with a priority for those counties with substantial acreages of crops earlier covered by the disaster payments program  (Gardner and Kramer, 1986, page 202).

• Catastrophic Risk Protection Program (1994 - now)

1- Yu, Smith and Sumner (2017) used this policy for the sensitivity analysis. 

• Farm Bills (1938 - now)

1- Yu, Smith and Sumner (2017) used Farm Bills of 1994, 2000 and 2008 for the sensitivity analysis. Their attention to choosing the pre and post years is instructive.

2- O'Donoghue, Roberts and Key (2009) used farm Bill 1994 to study the impact of increase in crop insurance coverage on farmers' diversification.

• Mandatory Premium-Free Catastrophic Crop Yield Insurance Policy (enacted in 1994 and rescinded in 1996)

For one year, only farmers who enrolled in the catastrophic insurance became eligible for other farm program benefits. 

3- Instrumental Variables

The Tsiboe and Turner (2023) paper (replication files) provides a great overview of endogeneity problem in modeling of crop insurance and reports on four general approaches of using Instrumental Variables for solving the identification problem in this context. Other resources are as following:

• Log of the initial premium divided by the maximum premium as an instrument for the log difference in coverage as measured by premiums per acre

     Weber, Key and O’Donoghue (2016) uses this IV. 

• Number of degree days greater than 30 degrees Centigrade as an IV for insurance indemnity.

Schoengold, Karina, Ya Ding, and Russell Headlee (2014) uses this IV.

• Membership on the House Appropriations Committee as an IV for disaster payments.

Schoengold, Karina, Ya Ding, and Russell Headlee (2014) uses this IV.
