In a floating exchange rate system, a currency's value goes up (or down) if the demand for it goes up more (or less) than the supply does. In the short run this can happen unpredictably for a variety of reasons, including the balance of trade, speculation, or other factors in the international capital market. For example, a surge in purchases ...
PPP then computes an inflation and exchange rate as the ratio of the price of the basket in one location to the price of the basket in the other location. For example, if a basket consisting of 1 computer, 1 ton of rice, and half a ton of steel was 1000 US dollars in New York and the same goods cost 6000 HK dollars in Hong Kong, the PPP ...
That is to say that, if and were constant or growing at equal fixed rates, then the inflation rate would exactly equal the growth rate of the money supply. An opponent of the quantity theory would not be bound to reject the equation of exchange, but could instead postulate offsetting responses (direct or indirect) of Q {\displaystyle Q} or of V ...
When export prices increase faster than import prices, the country’s revenue goes up, as does the demand for the nation’s currency. As more people want to buy the currency, the value increases.
The equilibrium price in the market is $5.00 where demand and supply are equal at 12,000 units; If the current market price was $3.00 – there would be excess demand for 8,000 units, creating a shortage. If the current market price was $8.00 – there would be excess supply of 12,000 units.
The concept of an excess demand function is important in general equilibrium theories, because it acts as a signal for the market to adjust prices. [2] The assumption is that the rate of change of the price of a commodity will be proportional to the value of the excess demand function for that commodity, eventually leading to an equilibrium state in which excess demand for all commodities is ...
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 ...
But if we look at mortgage rates (a factor other than price), even if housing prices remain unchanged, an increased mortgage rate leads to a lower willingness to buy at all prices, shifting the demand curve to the left. Consumers will buy less, even though the price is the same. [12]
