Sample text

Because effort will increase to the left of EBE and decrease to the right of it, there will be an equilibrium at this point. 7b. It occurs at the intersection of the total revenue and total cost curves in each case. This shows very clearly that all possible net gains will be dissipated in an open access fishery. The policy-relevant point is that open access utilization of a fishery will not lead to an economically efficient outcome. The equilibrium amount of effort will be higher than necessary, and it will lead to a lower equilibrium stock size than is appropriate.

However, it makes sense to posit that the change in effort will be proportional to the net returns per unit of effort. 4) The rate of proportionality, ϕ, is called the entry/exit coefficient. If the net returns per unit of effort are positive, effort will increase. If the net returns per unit of effort are negative, effort will decrease. 1. Recall that the PEC and the EEC divide the stock-effort space into four areas in which there will be particular types of changes in both stock size and the level of effort.

Effort and stock will both fall. Eventually, a point is reached where profits become negative and effort starts to decrease. However, since catch is still greater than growth, stock size continues to fall. When the path crosses the PEC curve, it will change again and move in a northwest direction. The decrease in effort has reduced catch to the point where stock size starts to increase. However, stock size is not high enough to generate positive profits, and so effort still decreases. When the path crosses the EEC again, the path will start to move in a northeast direction.
