William L. Wolfe,Eustace L. Dereniakand policy. Because of their comprehensiveness and discipline the flow-of-funds accounts are the ideal vehicle for theorizing about real and financial interaction. Such int- action can best be understood when real and financial transac­ tions are expressed in a common flow dimension. Each decision b

The flow-of-funds framework singles out financial flows as having a closer relationship to final expenditures than interest rates or the money stock.. Interest rate changes do not predict changes in nominal income because such vari

Rectilinear Scanners,t forms its image by moving over (scanning) the field of interest. Basically, the rectilinear scanner is a rigid bar with a radiation detector at one end and a light and a stylus at the other end (Fig. 3–1). When the detector detects radiation, the light flashes, exposing some film, and the stylus t
