Analytical results for steady-state values of the biomass that maximises the sum of inter-temporal economic profits (dynamic b_MEY) are derived in terms of a generalised harvesting function. The conditions under which dynamic b_MEY exceeds the biomass that maximises the sustained yield (b_MSY) are...

This paper analyses the dramatic increases in rice output and productivity in Vietnam due in large part to market reform, inducing farmers to work harder and use land more efficiently. The reform process is captured through changes in effort variables and a decomposition of total factor...
