Esuric,
It sounds like you agree with the pure theory of time-preference as an explanation for originary interest (i.e. time-preferences are the primary determinant of the natural interest rate), but that the theory is incomplete as an explanation for the market interest rate. That it needs to be supplemented with discussion of secondary phenomena, like changes in the demand for loanable funds. So that in the ERE, where they are no technological innovations, and no changes in liquidity preference, the market rate of interest will equal the natural rate of interest, which is determined solely by time-preferences (i.e. the ratio of demand between producer goods and consumer goods). Is that a fair summary of your position?
Assuming it is, I would ask that we leave all considerations of secondary phenomena out of this discussion, and just focus on what determines the natural rate of interest, i.e. what causes originary interest. Do you find ALL of Hulsmann’s and Murphy’s criticisms of PTTP to be spurious? Maybe you could respond to I Ryan’s critique in the first thread that I linked to?
