Fig. 3
From fig. 3 the following relations are evident:
φu break < φ self-selection < φu sustain <φs break < φs sustain
there exist therefore a range of trade costs for which a self-selecting equilibrium is possible (φ
self-selection < φ < φs sustain) and another smaller range for which is the only stable
equilibrium (φu sustain < φ < φs break).
The critical values considered depend on the parameters of the model. All the threshold
values are increasing in μ. If the share of manufactures in the economy is large, the
