Why should we care?
Important for development of India.
Consumers pay different prices in different regions.
Farmers in different locations face different prices.
They make crop choices and input choices given these prices.
Important to understand farm productivity and farmer welfare.

Data Sources
Time period 2005-2014. Commodities – Paddy & Wheat.
Monthly Wholesale price and quantity data. (Govt. of India’sAgmarknet Project).
Seasonal yields and production data at the district level. (Min-istry of Agriculture, GOI)
Monthly Rainfall - gridded data from Willmott and Matsuura(2012).
Population at sub-district level from Census of India 2011.
Farmer level data from NSS - Situation Assessment of Agricul-tural Households 2012-13.
District level monthly grain procurement - Food Corporation ofIndia.

Govt Procurement of Paddy and Wheat
Through Food Corporation of India and State Agencies
“Government policy of procurement of Food grains has broadobjectives of ensuring MSP to the farmers” – FCI Website.
Extensive Operations with about 20000 centers for Wheat and40000 centers for Paddy.
What does the data tell us?

Procurement varies widely in space

Procurement varies widely in space - even within states

Understanding Spatial Variation in Procurement:Some Hypothesis.
Presumably linked to spatial variation in procurement centers.
What drives this variation?
Path dependency - spatial variation of green revolution.
Fiscal Constraints.
Political Economy.

Half of all Mandi transactions are below MSP

Conclusions & Policy Questions
Core objective of MSP is not being met.
Large spatial variation in procurement and is likely to have sig-nificant welfare and distributional consequences.
Policy goal should be to provide more options to the farmers.
Regulations in APMC acts have created market power for man-dis which has clear price effects.
0-29
Conclusions & Policy Questions
Reforms under Model APMC Act –
Levies taxes on transactions outside the mandis.
Some states went back on reforms.
Has failed to attract private players.
NAM – welcome change but effects remain to be seen.
