Background Demand for fisheries commodities is expected to increase. In 2008,
222 I output transfer; J input transfer; K factor transfer; and L net transfer.
Here are the identities and ratios of PAM analysis [5]: Private profitability
[
= − + ] is a measure of competitiveness of
the agricultural business system at certain technologies, output prices, input costs, and applied policies. Social profitability [
= − +
] is a measure of efficiency or comparative advantages in prices that reflect
scarcity values or social opportunity costs efficiency price. Thus if D and H0, then the pangasius fish farming business is profitable in private and
social prices respectively. Private cost ratio [
= − ] and
domestic resource cost ratio [ = − ] are used to compare the
competitiveness and comparativeness of other agricultural systems that produce unlike outputs respectively. Private cost ratio and domestic
resource cost ratio show how much the system can afford to pay domestic factors and still remain competitive in its private and social prices
respectively. Thus if PCR and DRC is less than 1, then the pangasius fish farming business has competitive and comparative advantages respectively.
Nominal protection coefficient on outputs [
= ] and inputs [
= ] can be used to compare the output and input protection of other agricultural system respectively. Thus, if NPCO1 and NPCO1 then
the output and input in the pangasius fish farming business receiving protection.
