InSTePP United States Production Accounts

The InSTePP production accounts consist of an evolving series of accounts designed to track, analyze and help understand the nature and sources of production and productivity growth in U.S. agriculture. Construction of the accounts began in 1984 under the continuing leadership of Philip Pardey at the University of Minnesota's International Science and Technology Practice and Policy (InSTePP) center. The core elements of the accounts consist of aggregate input and output price and quantity indexes constructed for U.S agriculture at both the state and national levels. The accounts also include state and national level estimates of multi-factor productivity. Since the inception of the accounts, particular attention has been paid to adjusting for quality (compositional) change in the primary inputs of land, labor and capital.

This is an on-going area of interest for InSTePP. Each version of the accounts supersedes the previous version, but in the interests of continuity and transparency, older versions of the accounts are kept available on line. The analytical and policy products developed from these data are clustered below with the respective version of the series used to develop these products. Documentation of the procedures used to construct the accounts are available here.

Version 5 of the accounts consist of annual U.S. national and state-specific agricultural input, output and multi-factor productivity estimates spanning the period 1949-2007. This version of the accounts represents an update of the prior version, with no major changes to any methodological or other aspects related to the construction of the series.

Version 4 of the accounts consist of annual U.S. national and state-specific agricultural input, output and multi-factor productivity estimates spanning the period 1949-2002. In addition to bringing the series forward from 1991 to 2002, Version 4 includes some significant revisions to components of the series, with special attention paid to capital inputs. Mathew Andersen (University of Wyoming and InSTePP) led that effort, with additional input from Jason Beddow (University of Minnesota and InSTePP), Connie Chan-Kang, Michelle Hallaway and Philip Pardey.

Version 3 was the first release version of the accounts and consists of annual U.S. national and state-specific agricultural input, output and multi-factor productivity estimates spanning the period 1949-1991. It was developed by Barbara Craig and Philip Pardey with additional help from Albert Acquaye (then at University of California, Davis) and input from Julian Alston (University of California, Davis and InSTePP). This version of the accounts represents an update of the prior version, with no major changes to any methodological or other aspects related to the construction of the series.

 

Version 3 authors: Barbara Craig, Philip Pardey and Albert Acquaye

Versions 1 and 2 are the initial, exploratory, unpublished versions of the InSTePP production accounts, covering the period 1949-91. The series was initiated and developed by Barbara Craig (now at Oberlin College) and Philip Pardey, with substantial input from Michelle Hallaway and Connie Chan-Kang, both from InSTePP, and Louise Letnes, then at the Department of Applied Economics, University of Minnesota. At the time of instigating this line of work in the early 1980s, the lack of state-level aggregate input, output and productivity data was a major motivating factor. So too was the lack of explicit attention paid to accounting for quality (compositional) changes in agricultural inputs, especially in relation to key factors such as land, labor, and capital. Both aspects are areas of continuing attention for the InSTePP Production Accounts.
