Purchasing Power Parity
Purchasing Power Parity (PPP), also known as the law of one price, operates under the assumption that product prices in one country translate into an equal price in another country. The price similarity assumption is used to gauge currency exchange rate pressures. If the law of one price is assumed, then the premise establishes that the relational value of currencies must converge to equilibrium. The equation expresses that any inequality creates an arbitrage opportunity until equilibrium returns.
At best, the PPP is a rudimentary tool for long-term pricing pressures, however the simplicity of the equation is part of its shortcoming. Annual price level comparisons by The Economist illustrate that even the most uniform of products, for example the McDonald's Big Mac, provides little proof for the reliability of the PPP. Comparing the 2010 to 2012 Big Mac Index illustrates that none of the countries compared demonstrated price parity to the U.S. average cost, or consistent convergence towards parity.[footnoteRef:1][footnoteRef:2][footnoteRef:3] The St. Louis Federal Reserves notes that, "Clearly, absolute PPP does not hold strictly for the currencies of countries reported," and...
The policy prescription for the classical economist will not be to adjust inflation in order to deal with unemployment. In the short run, the classical economist may view that the Phillips Curve holds, but only until the point where workers become informed, at which point they would demand an increase in real wages. In today's information-rich economy, this time lag would be small to the point where a classical
If the average person has two sets of clothes in one society and thirty in another, then the parity of price of clothes is hard to assess. It certainly cannot be assessed in terms of the cost alone or the number of outfits that a person "should" have (Taylor & Taylor, 2004). It might be set at the percentage of annual wages that a person spends on clothing, but
). Basket of Goods the PPP exchange rate calculations are also controversial because of the difficulties involved in finding comparable 'baskets of goods' to compare purchasing power across countries. People in different countries typically consume different baskets of goods; assign varying priorities to different goods; and even the goods available for purchase may differ across countries. Moreover, what is considered a luxury in one culture could be considered a necessity in
purchasing power parity (PPP) states that the exchange rate between two currencies is related to the relative prices in the two countries so that exchange rate-adjusted prices will be equal between the two countries (Norrbin, and Conover). (Dryden, Reut, and Slater) further stated that, as purchasing power parities (PPP's) are nothing more than interspatial price indexes (by analogy with the inter-temporal price indexes such as consumer price indexes), the methodology,
Global Imbalances in Trade and Purchasing Price Parity: Evidence From Research and Current Trends The recent global economic collapse threw into sharp relief the degree to which the world's economies are inextricably linked and co-dependent. A failure in one major economy will automatically and almost instantly have a negative effect on the other major economies of the world, and these effects trickle down in a substantial stream to all but the
Purchasing power parity dictates competitive advantages within international finance. According to the theory of purchasing power parity, "the exchange rate between currencies of two countries should be equal to the ratio of the countries' price levels" (Eun & Resnick, 2012). Essentially, this sets the concept that price levels of currency have an impact on purchasing power and competitive advantage of countries within the international market environment. In this sense, "PPP
