 Period: 1953-59 

 Period: 1964-71 

 Region: Northwest 



Notes: 



Observations are on 15 states for the 1953-71 period. 



Dependent variable: state productivity index. 



Independent variables: 

 State research (S) = indigenous state research expenditures, cumulated from 

 1953 to / and deflated by the I960 value of resources devoted to agricultural 

 production in the slate. The 1953 research stock was assumed to be five times 

 the 1953 expenditures. A distributed lag over a ten-year period was used to 

 cumulate new research. 



Regional research (R) = cumulated research expenditures of research 

 programs conducted outside the state, but within the same major geo-climate 

 region, deflated by the state research deflators. 



Extension = a measure of the maturity of the extension program in the state: 

 (.25 X stage 1 blocks + .75 x stage 2 blocks + .25 stage 3 blocksVtotal blocks. 

 Drought = dummy for drought years, i.e. years in which production dropped 

 more than 10% below trend. 



Period = dummy variable for average annual number of publications in the 

 agricultural sciences for the 1960-65 period, which were abstracted in Indian 

 Indian Science Absiracis. 

 Region = dummy, 1.0 for the Northwest Region. 



In parentheses: / ratios.
