The purchasing power parity theory Rating:
Purchasing power parity (PPP) is an economic theory that suggests that exchange rates between currencies are determined by the relative prices of a basket of goods and services in each country. According to the theory, the exchange rate between two countries should equal the ratio of the prices of the same basket of goods and services in each country. In other words, the theory suggests that a unit of currency should have the same purchasing power in all countries.
The PPP theory is based on the idea that people will naturally seek to purchase goods and services at the lowest possible price, regardless of the country in which they are located. If the price of a good or service is higher in one country than in another, people will be more likely to purchase it in the country with the lower price. This will lead to an increase in demand for the cheaper currency and a decrease in demand for the more expensive currency, resulting in an appreciation of the cheaper currency and a depreciation of the more expensive currency.
The PPP theory can be used to explain long-term trends in exchange rates between countries. For example, if the price of a basket of goods and services is higher in Country A than in Country B, the PPP theory would predict that the currency of Country A would depreciate against the currency of Country B over time. This is because people in Country A would be more likely to purchase goods and services from Country B, leading to an increase in demand for the currency of Country B and a decrease in demand for the currency of Country A.
There are several limitations to the PPP theory. One limitation is that it assumes that prices of goods and services are equal across countries, which is not always the case. Another limitation is that it does not take into account other factors that can affect exchange rates, such as changes in interest rates, inflation rates, and economic policies. Despite these limitations, the PPP theory is still widely used by economists and policymakers to understand and predict long-term trends in exchange rates between countries.
In conclusion, the PPP theory is an important economic theory that suggests that exchange rates between countries are determined by the relative prices of a basket of goods and services in each country. While the theory has limitations, it is still widely used to understand and predict long-term trends in exchange rates.
What is Purchasing Power?
This is a completely price-level theory, which only looks at the exact same basket of goods in each country, with no other factors included. This indicates that the rupee may buy more goods than the dollar. This theory involves a basket of goods that are traded between markets should cost the same in different markets. While this was superior to earlier "bridging" methods, which do not fully take into account differing quality between goods, it may serve to overstate the PPP basis of poorer countries, because the price indexing on which PPP is based will assign to poorer countries the greater weight of goods consumed in greater shares in richer countries. This would give you the rate of depreciation for one currency compared to another, and an estimate of the future exchange rate.
