The Mundell–Fleming model portrays the short-run relationship between an economy's nominal exchange rate, interest rate, and output (in contrast to the closed-economy IS-LM model, which focuses only on the relationship between the interest rate and output). The Mundell–Fleming model has been used to argue [3] that an economy cannot ...
The IS–LM model shows the importance of various demand shocks (including the effects of monetary policy and fiscal policy) on output and consequently offers an explanation of changes in national income in the short run when prices are fixed or sticky. Hence, the model can be used as a tool to suggest potential levels for appropriate ...
How it works: fixed rates. With a fixed-rate product, such as a personal loan or savings account, the interest rate you sign up for is the interest rate you’ll either pay or earn for the life of ...
In the short-run none of these conditions need fully hold. The price level is sticky or fixed in response to changes in aggregate demand or supply, capital is not fully mobile between sectors, and capital is not fully mobile across countries due to interest rate differences among countries and fixed exchange rates.

Calculating option prices, and their "Greeks", i.e. sensitivities, combines: (i) a model of the underlying price behavior, or "process" - i.e. the asset pricing model selected, with its parameters having been calibrated to observed prices; and (ii) a mathematical method which returns the premium (or sensitivity) as the expected value of option ...
Under the standard assumption of neoclassical economics that goods and services are continuously divisible, the marginal rates of substitution will be the same regardless of the direction of exchange, and will correspond to the slope of an indifference curve (more precisely, to the slope multiplied by −1) passing through the consumption bundle in question, at that point: mathematically, it ...
In economics, nominal rigidity, also known as price-stickiness or wage-stickiness, is a situation in which a nominal price is resistant to change. Complete nominal rigidity occurs when a price is fixed in nominal terms for a relevant period of time. For example, the price of a particular good might be fixed at $10 per unit for a year.
Following the tradition of classical economics, Pigou favoured the idea of "natural rates" to which the economy would return in most cases, although he acknowledged that sticky prices might still prevent reversion to natural output levels after a demand shock. Pigou saw the "Real Balance" effect as a mechanism to fuse Keynesian and classical ...
