Speech, more than any policy narrative, causes nonlinearities of growth -- the leap outwards from the production possibility frontiers
Chapter 4 by Eirik Romstad brings in a theoretical discussion about the nature of public and private goods, production possibility frontiers
of public goods in terms of their relative prices.
The table shows that revealing the relative sizes of the PPFs (production possibility frontiers) before the start of the experiment enabled improvement over autarky for most teams.

Key words: benchmarking, production possibility frontiers, efficiency/inefficiency measurement, J-Curve of adoption of innovations, convergence.
In the early literature on production possibility frontiers (see, for example, AIGNER & CHU, 1968; AFRIAT, 1972), it was assumed that the leader of a sample was always reaching the boundary of the frontier.
Moreover, since some production factors are, at least, partly commodity-specific, the reorientation of output pattern can follow only along the new production possibility frontier which in the short-run should lie inside the previous one.
In Figure 4, [PPF.sub.p] represents the production possibility frontier of a planned economy in which output composition is fixed by the "centre" in point Ep, and does not match consumers' preferences (this point displays the deliberate violation of the Paretian condition that requires the marginal rate of transformation in production to equal marginal rates of substitution in consumption).
