| Abstract: | A bioeconomic model of reservoir aquaculture in northern Vietnam is used to
investigate the impacts of price and yield risk on the level, variability and skewness of
expected net revenue and utility. Prices and yields are assumed to follow lognormal
and beta distributions, respectively. Net revenue follows a generalized gamma
distribution and is found to be very risky compared with similar enterprises
elsewhere, mainly due to the relatively high yield risk. This represents the nascent
nature of the industry in Vietnam and the opportunity for efficiency improvements.
Increasing production capacity (through increasing reservoir size, stocking density,
production cycle length and harvest rate) are found to increase profits and decrease
the variability of profits. Species diversification was found to reduce the riskiness of
the enterprise. |
