Problem Set #4
reverse comparative advantage. This means that the British cost, and thus autarky price, of croissants is reduced, reducing p~B. It does not change Britain's maximum output of crumpets, however, so B cru F ˆ cro /X ˆ is unchanged. Thus the upper horizontal portion of the RS curve shifts down to one of the positions shown as RS' and RS'' above. In the first case, the world equilibrium ...

A. Abutment In coal mining, (1) the weight of the rocks above a narrow roadway is transferred to the solid coal along the sides, which act as abutments of the arch of strata spanning the roadway; and (2) the weight of the rocks over a longwall face is transferred to the front abutment, that is, the solid coal ahead of the face and the back abutment, that is, the settled packs behind the face.

Spontaneous changes, also called natural processes, proceed when left to themselves, and in the absence of any attempt to drive them in reverse. The sign convention of changes in free energy follows the general convention for thermodynamic measurements. This means a release of free energy from the system corresponds to a negative change in free energy, but to a positive change for the ...
