Milton Friedman discussed the possibility of setting the marginal social cost of printing one more unit of money to zero, implying that the real interest rate should be equal to the rate of deflation in the economy, but not everyone agreed with this. What reasoning did Phelps (1973) provide to argue against Friedman's rule? Which interpretation would be correct in the RBC model? Why?

Answer and Explanation:

Phelps criticized Friedman's position, because he said it was totally irrelevant to analyze the tax functions of inflation without assessing product demand, as Friedman suggested in his theory. He stated that this would only be possible if there was a way to predict an optimal rate of inflation in different situations of demand and supply, otherwise, in Phelps' words it would be the same as "Professor Friedman gave us Hamlet without a prince".

Phelps' positioning would be better considered by the RBC model, since this model is based on real and not imaginary facts.

i believe the answer is:   psychological  experiment

in this experiment, wilhelm wundt became the first person that implement scientific method in analyzing the pyschological phenomenon.

due to this result, wilhelm wundt also able to make psychology to be acknowledged as a separate scientific field from biology.

question - in 1827, john walker, a druggist in a small english town, tipped a splint with sulphur, chlorate of potash, and sulphid of antimony, and rubbed it on sandpaper, and it burst into flame. the druggist had discovered the first friction-chemical match, the kind we use to-day. it is called friction-chemical because it is made by mixing certain chemicals together and rubbing them. although walker's match did not require the bottle of acid, nevertheless it was not a good one. it could be lighted only by hard rubbing, and it sputtered and threw fire in all directions. in a few years, however, phosphorus was substituted on the tip for antimony, and the change worked wonders. the match could now be lighted with very little rubbing, and it was no longer necessary to have sandpaper upon which to rub it. it would ignite when rubbed on any dry surface, and there was no longer any sputtering. this was the phosphorus match, the match with which we are so familiar. according the paragraph what was the benefit of the new phosphorus match? it burst into flame when rubbed on sandpaper. it was made by mixing chemicals. it could be ignited on any dry surface. it threw fire in all directions.

answer - matches required natural chemicals
