Countercurrent exchange is a mechanism occurring in nature and mimicked in industry and engineering, in which there is a crossover of some property, usually heat or some chemical, between two flowing bodies flowing in opposite directions to each other. The flowing bodies can be liquids, gases, or even solid powders, or any combination of those.
Countercurrent multiplication. A countercurrent mechanism system is a mechanism that expends energy to create a concentration gradient. It is found widely in nature and especially in mammalian organs. For example, it can refer to the process that is underlying the process of urine concentration, that is, the production of hyperosmotic urine by ...
The value Keynes assigns to his multiplier is the reciprocal of the marginal propensity to save: k = 1 / S '(Y ). This is the same as the formula for Kahn's multiplier in a closed economy assuming that all saving (including the purchase of durable goods), and not just hoarding, constitutes leakage.
Chapter 10 introduces the famous 'multiplier' through an example: if the marginal propensity to consume is 90%, then 'the multiplier k is 10; and the total employment caused by (e.g.) increased public works will be ten times the employment caused by the public works themselves' (pp116f). Formally Keynes writes the multiplier as k=1/S'(Y).
This is a return of US$20,000 divided by US$100,000, which equals 20 percent. The US$20,000 is paid in 5 irregularly-timed installments of US$4,000, with no reinvestment, over a 5-year period, and with no information provided about the timing of the installments. The rate of return is 4,000 / 100,000 = 4% per year.
Thirlwall's law (named after Anthony Thirlwall) states that if long-run balance of payments equilibrium on current account is a requirement, and the real exchange rate stays relatively constant, then the long run growth of a country can be approximated by the ratio of the growth of exports to the income elasticity of demand for imports (Thirlwall, 1979).
A simple way for investors to look at RRR is: RRR = Risk-Free Rate + Risk Premium. For example, if the risk-free rate is 2%, and the risk premium for a specific investment is 4%, RRR would be 2% ...
The simple inflation rate ISt from t –1 to t is . Thus, continuing the above nominal example, the final value of the investment expressed in real terms is. Then the continuously compounded real rate of return is. The continuously compounded real rate of return is just the continuously compounded nominal rate of return minus the continuously ...
