This paper uses the agricultural census micro data of 1995-1996 to calculate, for each of the five Brazilian macro regions, the difference in total factor productivity (TFP), with two cleavages: family farmers and input-intensive farmers. This difference in TFP is explained regarding to variables of size, supply of public goods and access to institutions, and local variables measured directly or through a municipality fixed effect. The results point out to: a) the inverse relationship between land productivity and size, a stylized fact in the literature, is verified in all regions, but the inverse relationship regarding TFP and size is verified only to North, Northeast and Southeast and for the non-intensive in other regions; b) the family farmer has higher land productivity in seven of ten cases but lower TFP in eight of ten cases. Most of this difference is due to non-observable variables; and c) the intensive-type farmer is more productive in regions and non-observable variables explain part of the difference in productivity against their counterparts.
