Implied PPP of the Dollar and Actual Exchange Rate

Implied uvulopalatopharyngoplasty of the Dollar and Actual Exchange RateQues. The economic expert publishes every year the prices of a standard BigMac around the world. Find the BigMac prices for the USA, France, and South Korea and the corresponding (average annual) nominal mass meeting identifys in 2006 and 2009. Calculate for each of these countries the implied uvulopalatopharyngoplasty of the sawhorse 2006 and 2009 and compare this to the actual substitute rates. Can you apologise the discordences in implied PPP of the dollar and the nominal exchange rates?The Economists Big Mac list is an informal indicant sometimes used to judge whether current exchange rates between different currencies are justified and currencies are at their even out exchange rate, though it is non intended to be a precise predictor of currency movements. Now commonly known as burgernomics, it is based on the theory of Purchasing Power Parity (PPP). PPP is the notion that a dollar should buy the said(prenominal) amount of goods in all countries. It suggests that a extensive term equilibrium entrust adjust exchange rates such that the purchasing power or cost of traded goods and services in different countries will be the same. It is based on thelaw of one price in ideally efficient markets, selfsame(a) goods should have only one price.The Big Mac index uses the prices of McDonalds Big Mac hamburger, which is produced in about 120 countries. It assumes that the Big Mac is a resembling product in each economy, wherever produced, and it is made with identical specification, thus it should have the same price everywhere.The following tables compare the Big Mac prices, nominal exchange rates and the Implied PPP for USA, France and South Korea for the year 2006 and 2009. analyse actual exchange rates with PPPs indicates whether a currency is at a lower place- or over- valued. A countrys currency is said to be overvalued if the implied PPP is greater than the market exchange rate and it is said to be undervalued if the implied PPP is less that the market exchange rate.In accordance with the above explanation, Euro is overvalued both in 2006 and 2009 i.e. the implied PPP is more than the nominal exchange rate. The Euro has appreciated in 2009 as compared to 2006, but the nominal exchange rate should come down by about 28%(for 2009) and 19%(for 2006)to equalise with the implied PPP and thus holding the law of one price true. Whereas, the South Korean Won is undervalued both in 2006 and 2009, as implied PPP is less than the nominal exchange rate. We notice that the Won has depreciated in 2009 as compared to 2006, but the nominal exchange rate should go up by 26%(for 2009) and 17%(for 2006)to equalise with the implied PPP.The under/over valuation of Euro and South Korean Won for 2006 and 2009 is shown belowThere is a difference between the nominal exchange rate and the implied PPP of the dollar as calculated using Big Mac prices. This difference can be attr ibuted to several factors.The difference can arise largely due to factors modify eitherThe implied PPP by Big Mac indexOrNominal Exchange RateFirstly, the difference arises because the actual prices of Big Macs are not same everywhere. Many of the inputs of a Big Mac cannot be traded internationally, thus the prices of these goods may diverge substantially between countries. This effects the PPP but not the nominal exchange rate because comparisons on a purchasing-power likeness (PPP) basis take account of the variations in prices of the same goods in different countries. Unlike comparisons at market exchange rates, PPP reflects the unfeigned purchasing power of each countrys residents.The Big Mac index is most useful for assessing the exchange rates of countries with similar incomes per head. It is quite natural for average prices to be lower in poorer countries than in developed ones. Non tradable inputs like labour services and property rent generally differ and are particular ly cheap in poorer countries. This gives a big cost advantage in production of these goods and services. PPPs are therefore a more authoritative way to derive exchange rate than market exchange rates, because cheaper prices mean that money goes further. The prevailing rates of taxes also lead to a difference in input prices and the selling price of a same commodity in different regions.The PPP model assumes that the real value placed on goods is same in different countries. But in reality, what is considered a luxury in some places might be a necessity in others. The PPP rule does not take this into consideration.On the other hand, the factors which effect the nominal exchange rate are price level of the two countries in question, inflation rates, the real exchange rate etc. There factors might not always affect the PPP, thus there is a difference between the two.The above points explain the differences between implied PPP and nominal exchange rate.The believers of PPP have based their views largely on arguments relating to international goods arbitrage, which leads to equilibrium but this is not always the case. consequently Big Mac index is not a perfect measure of exchange rate.Referenceswww.oanda.com/convert/fxhistorywww.economist.com/markets/bigmacBig Mac IndexA Dictionary of Finance and Banking.
