This area was chosen because we
could obtain a reliable data set for one village in the
area about farmers' marketing outlets of paddy produced.
This village, henceforth called 'East Laguna
Village,' was one of 13 barangays in the municipality
of Pila, for which recurrent surveys were organized by
IRRI's Social Sciences Division for the past two
decades (Hayami et al., 1978; Hayami and Kikuchi,
1981, chap. 5; Hayami et al., 1990).
