In this study, we examine the revenue, costs, profits and technical efficiency of chilli farms in Cambodia. We employ a representative sample of 542 chilli farming households from Banteay Meanchey, Battambang, Kampong Chhnang, Kampong Cham, Tboung Khmum and Kandal. The sample was randomly selected using a two-stage stratified sampling design, where villages were chosen in the first stage as the primary sampling unit and households engaged in chilli production were selected in the second stage as the secondary sampling units.
