components of the international market (international trade, foreign exchange and capital market) are explained by the economic theories called the international parity conditions It is considered to be unique to the field of International Finance (Eiteman, Stonehill and Moffett 2006:102) Deriving from the Law of one price, the absolute form of purchasing power parity (PPP) states that if the market is frictionless the price of identical products and services should be the same in different markets For instance, if the price of the product in Australian dollar is PAUD, then the price of the identical product in U.S dollar (PUSD) should be equal to PAUD adjusted for exchange rate (SUSD/AUD), or PAUD x SUSD/AUD = PUSD Thus, the nominal exchange rate can be simply expressed as the ratio of the two prices (SUSD/AUD = PUSD / PAUD) If this is not the case, the arbitrageurs in an efficient market could make riskless profit by shipping the goods from locations where the price is low to locations where the price is high (Taylor and Taylor, 2004) They will trade the opportunity away and bring the conditions back to “parity” If the PPP holds perfectly the nominal exchange rate adjusts to maintain a constant real exchange rate equal to The relative form of PPP involves only that the change in nominal exchange rate offsets the differential between home and foreign price level While international trade plays a vital role in a PPP , obviously the market frictions such as transportation cost, taxes, tariffs and duties, and non-tariff barriers such as quotas and import licenses are the main causes of some deviations from PPP In recent years we have seen the emergence of multinational and bilateral free trade arrangements where governments set the objectives to bust up trades by removing trade barriers Australia has joined WTO and signed free trade agreements with the United States and Thailand in 2005, with Singapore in 2003 and with New Zealand from 1993 It is now in negotiating Free Trade Agreements with other countries and areas such as Japan, ASEAN, Malaysia, China, Chile and Gulf countries This research project tests the PPP between Australia and its trading partners over the period from 1984 to 2006 and provides some insights on particular effects that the level of bilateral trade and investment have on their PPP Using quarterly of foreign exchange rates and proxy for country price level (both consumer price index and producer/whole sales price index) evidence from my sample shows that PPP holds for Research Project in International Finance: 2007 Dang H Pham some countries while it does not hold for others Further, the higher level of bilateral trade significantly and positively associates with the higher level of PPP Foreign investment level is found to have positive impacts on PPP but not significantly This research is outlined as follows: Part II reviews PPP literature, in which the subsection on PPP theoretical background highlights the law of one price and the role of international trade as crucial conditions for the existence of the parity condition An overall picture about extant empirical literatures on PPP including Australian evidences is provided in subsection and From these reviews we develop our arguments about the impacts of trade and investment on the PPP s between Australia and its trading partners Part III presents the hypothesis our research and the methodologies, models we use to test the hypothesis in details Part IV describes and discuss about the data used in our research The results of this research are reported and discussed in Part V Conclusion is provided in Part VI; and Part VII proposes some direction for future research Research Project in International Finance: 2007 Dang H Pham II LITERATURE REVIEW Theoretical background Economists widely believe that the PPP theory hold at least approximately because of the possibility of the international goods market arbitrage In the formal way, the PPP theory states that the percentage change in the exchange rates over a given period simply offset the difference in inflation rates in the countries concerned over the same period Therefore, in the relative form of PPP, according to Eiteman et al (2006:105), “if a country experiences a higher rate of inflation, and its exchange rate does not change, then its goods prices will be relatively more expensive” Eiteman et al (2006:105) also states that “if the spot exchange rate between two countries starts in equilibrium, any change in differential rate of inflation between them tends to be offset over the long run by an equal but opposite change in the exchange rate” Hence, the relative PPP is useful for forecasting the spot exchange (long run) rates from the expected inflation rates in the two countries The model is described as follows: E ( S th / f ) (1 + π h ) t = (1.1) or ΔS h / f = π h − π f (1.2) h/ f t S0 (1 + π f ) Where: E ( S th / f ) is the expected spot exchange rate at time t, S 0h / f is the current spot exchange rate, π h is the inflation rate in home country and π f is the inflation rate in foreign country ΔS h / f is the change in spot exchange rate in a period of time t However, international goods markets are far less liquid than financial markets and the frictions seem to be considerable and it is the fact that there is in existence goods that fall outside the various range of homogeneous goods Therefore, short-run international arbitrage has only limited effect of leveling international goods market prices (Rogoff, 1996) While the traditional PPP theory holds that the real exchange rate should be constant and equal to 1, there is another assumption of long-run deviations from PPP Harrod (1933), Balassa (1964) and Samuelson (1964) build their model of the equilibrium exchange rate on the observation that rich countries tend to have higher price levels than poor countries This is because rich countries are relatively more productive in the traded high-tech goods and they grow richer as a result Income rises as a result of Research Project in International Finance: 2007 Dang H Pham the higher productivity in tradable goods will cause price level to rise also This effect modeled by Harrod, Balassa and Samuelson seem to be stronger over time where data show a strong positive relationship between income and price level If this is true, then the real exchange rate is not constant over time In general, as PPP theory is derived from the law of one price, its basic condition is the perfect international trade of goods and services If there is no trade, obviously no PPP exists The perfect trading market (without friction and transaction costs) is the key assumption in PPP theory In this research, an examination on PPP relation between Australia and its different trading partners to find out the consistency and inconsistency with the above-mentioned assumption is therefore necessary Empirical evidences about PPP There has been a heightened level of extant literature on the validity of PPP The results of the PPP tests varies according to according to whether (i) price and exchange rate levels (absolute PPP) or changes in prices and exchange rates (relative PPP) are studied; (ii) individual commodity prices or nominal price levels are employed; (iii) purely traded goods’ prices or non-traded as well as traded goods prices are considered; (iv) bilateral or multilateral approach is adopted; and (v) the short run or the long run is investigated (Rush and Husted, 1985) In the respect of long-run or short-run validity of PPP, for example, evidence from Edler and Lehmann (1983), Enders (1988) and Ardeni and Lubian (1991) reject long-run PPP However, Diebold, Husted and Rush (1991), Cheung and Lai (1993), Edison (1987), Frenkel (1981), Branson (1981), Desai (1981), and Miller (1986) strongly support that the PPP holds in the long run and poorly in the short-run Cooper (1994) claims that the main reasons for the inconclusive results are due to the difference in particular currencies under consideration, the price indices used to measure price levels of inflation, and the method of analysis employed Early empirical tests (mainly in the 1970s) find support for the long-run and continuous PPP (Frankel, 1976 and1981) This might be partly due to the data of a period of stable exchange rates (few years post-float after 1971- collapse of the Bretton Woods Agreement) On the other hand, PPP deviates significantly from equilibrium in the short-run PPP due to the sticky nominal prices (Dornbusch, 1976) However, there is no evidence of how far exchange rates deviate from the mean and how fast they revert to the mean, knowing that mean reversion of exchange rates Research Project in International Finance: 2007 Dang H Pham toward its mean is the key characteristic and necessary condition for long-run PPP to hold (Taylor and Taylor, 2004) Studies employing unit root test of real exchange rate (the null hypothesis is that real exchange rate follow a random walk) could not reject the random walk (see, for example, Roll 1979); Contemporary empirical studies of PPP are dominated by unit root tests with more advanced techniques Frankel ( 1986) tests the first order autocorrelation model for ~ ~ ~ the real exchange rates: (e1 − e ) = δ (et −1 − e ) + ε t where e is the assumed constant equilibrium real exchange rate and δ is the autocorrelation coefficient If δ >1 it is an explosive process; if δ =1, then exchange rates follow a random walk; if δ critical value then we reject the null hypothesis to accept the alternative Otherwise, we cannot reject the null hypothesis and conclude PPP holds For the purpose of ranking the level of PPP between different trading partners, we also look at p value and R-squared as supplementing measures Effects of trade and investment on PPP Since the actual relationship between exchange rates and price levels often deviate from the parity and tend to revert from time to tine Reasonably, the more exchange rates deviate from the theoretical PPP the less PPP holds for that currency We measure the deviation from the equation of relative form of PPP as follows: S th / f (1 + π h ) t PPPdeviation = h / f − S t −1 (1 + π f ) t (2.2) π h and π f are home and foreign quarterly inflation rates respectively (based on CPI change); and S th−/1 f and S th / f are exchange rates at time the quarterly change in the nominal exchange rate at time t and t-1 Effects of trade and investments on PPP is estimated from the regression of PPP deviations against annual trade weights and foreign direct investment level in the following model: PPPdev = β + β1Trade + β Investment + ε t (2.3) The sign and the significance of β1 and β estimated from (2.3) indicate the effect of trade and foreign investment on PPP 12 Research Project in International Finance: 2007 Dang H Pham IV DATA Among Australia trading partners, we select 12 countries/currencies that their trading weights range from the high to low across the sample period from 1984 – 2005 (See Table 1) for our sample Table List of currencies of Australia’s trading partner countries selected for PPP test The trade weights represent the level of trading between that country and Australia No Currency Japanese yen Chinese renminbi European euro United States dollar South Korean won Singapore dollar New Zealand dollar United Kingdom pound sterling 10 11 12 Malaysian ringgit Indonesian rupiah Canadian dollar Swiss franc Average Trade Weights (%) 16.95 8.92 12.81 14.62 6.16 4.25 5.71 5.23 3.01 2.99 1.57 0.78 (According to trade weights table announced annually by RBA) The quarterly nominal exchange rates of Australian dollar to the 12 currencies for the period from 1984 to 2006 are collected from the Website of the Reserve Bank of Australia We obtain quarterly Consumer Price Index (CPI) and Producer Price Index (PPI)/Wholesale Price Index (WPI) (from hereon PPI and CPI are referred to as PPI for convenience) of the 12 countries for the same period from Datastream-economics database ΔS th / f is calculated from the quarterly nominal exchange rates between the Australian dollar and the foreign currency The selection of quarterly data deriving from the needs that time interval should be long enough for the differences in countries’ inflation rates to take effect on the corresponding exchange rates Changes in nominal exchange rates are estimated from the following formula: S t − S t −1 Inflation rates S t −1 WPI is used instead of PPI for countries that PPI is not available (for example Australia) 13 Research Project in International Finance: 2007 Dang H Pham are measured using CPI and PPI by the following formula: CPI t − CPI t −1 CPI t −1 and PPI t − PPI t −1 We use both CPI and PPI for our PPP test because some countries’ PPI t − trading relationship with Australia may rely on industrial go than consumer goods Then, theoretically, the parity conditions are guaranteed by the arbitrage activities in industrial goods markets rather than consumer markets Hence, PPI is better than CPI to reflect the PPP with those countries This is also consistent with the extant literature that several studies use both CPI and whole sale price index (WPI) (See, for example, Chinn 1999) Further, In and Sugema (1995) and Bhati and McCrae (2004) indicate that there is no evidence determining whether CPI or WPI is better The exports and imports between Australia and the 12 countries are collected from the database of UNCTAD Foreign Direct Investment (FDI) into Australia and from Australia to the 12 countries are collected from database of UNDP However, the FDI data are only available from 1992 to 2003 Therefore, we the test of the effect of trade on PPP separately first And then we the second test to see the effects of both trade and FDI on PPP in a multivariate regression using data from 1992-2003 The time-period of data in this case is quite short for an examination of long-run PPP we not expect to obtain significant results from this test However, the signs of the effects are also helpful for the future research direction 14 Research Project in International Finance: 2007 Dang H Pham V RESULTS DISCUSSION PPP with 12 countries Table reports results of our regression model (2.1) using OLS method CPI changes are used as proxy for the inflation rates in home (Australia) and foreign countries If we set 5% significance level to reject the null hypothesis, the results indicate that we reject PPP for countries PPP holds only for Malaysia, United States and United Kingdom Table also ranks the countries from high level of PPP to low level (even insignificant) PPP with New Zealand is not rejected if we set the significance level at 10%, showing that New Zealand is quite close to United Kingdom in the level of PPP It should be noted that Japan, which is always the biggest trading partner of Australia, shows an insignificant PPP and relatively weaker than many smaller trading partner Although, China is the second largest trading partner of Australia now, PPP with China is at lowest level This may be due to the Chinese exchange rate regime Table α and β are estimated from equation ΔS th / f = α + β (π h − π f ) + ε using OLS method CPI is used to measure the inflation

in International Finance: 2007 Dang H Pham PPP is rejected with many countries as reported in Table when CPI is used to estimate the inflation rates in both countries The CPI index reflects the price level of a basket of consumer goods The extent to which CPI represents a country general price level depends on the market structure that country Also, the degree to which any differences in CPI level between two countries depends on the size of the trading on consumer goods relative with other foreign trade markets (e.g industrial goods markets) It is reasonably for us to another test that use PPI index as proxy for country price level We expect that the industrial goods market may be more influential on foreign exchange rates fluctuation than the consumer goods market The results of the second test using PPI changes as proxy for the inflation rates are reported in Table Table α and β are estimated from equation ΔS th / f = α + β (π h − π f ) + ε using OLS method PPI/WPI is used to measure

Research Project in International Finance: 2007 Dang H Pham The results in Table indicate that only PPP is rejected for only countries (at 5% significance level) or only for countries if 10% significance level is set Overall, the PPP holds better when our test use PPI as proxy for price level In particular, the PPP holds better with CPI for some countries (New Zealand and Canada), while for almost others, PPP holds better with PPI (e.g Korea, Singapore, Japan and China) We argue that industrial goods market with Australia may have much more influential on foreign exchange rate than the consumer goods market Figure and Figure present the structure of Australia’ foreign trade Figure Australia Imports in two different markets – Industrial and Consumer Australia Imports 35000

dominates both Australia’s import and export trading activities This fact explains, to some extent, why in general PPP holds better when PPI is used as proxy for the price levels For country specific cases, countries such as New Zealand and Canada may have the same comparative advantages as Australia (natural resources and agriculture products) Therefore, their industrial markets with Australia are less important than consumer market, which explains the worse PPP found when using PPI as proxy Our results confirm the findings in previous studies (see, for example, Bhati and McCrae, 2004; and Cooper, 1994) One important reason for the rejections of PPP in both tests using CPI and PPI is the impact of transaction costs Sercu, Uppal and Hulle (1995:1317) state that “In reality, though, commodity trade is costly As a result of these costs, international imbalances between marginal utilities will be left uncorrected as long as they are sufficiently small relative to the cost of shipping” Hence, the long distance between Australia and America, Europe could partly imply relatively higher transactions costs so as to negatively impact the PPP Furthermore, capital mobility (excluding FDI) is recently considered a major force that may distort the PPP since a huge amount of capital assets transactions creates a 18 Research Project in International Finance: 2007 Dang H Pham great impact on exchange rates The CPI indices never reflect international capital transactions Cooper (1994: p.170) claims that the reason that PPP poorly explains exchange rates is that: “ it ignores capital flows In recent years, capital has been free to move from country to country Cross border trade in financial assets swamps foreign exchange transactions in goods and services It is estimated that almost US$ 100 trillion equivalent is traded annually on foreign exchange markets and it is twenty times the value of the World trade in goods.” United States and United Kingdom are the largest sources and destination of capital mobility (excluding FDI) in and out of Australia This could partly explain why they are larger trading partners than other countries but PPP levels are lower Figure and Figure show the level of capital (excluding FDI) mobility between Australia and some foreign countries Figure 1: Foreign Investment in Australia, 31 December 2005 (Source: Australian Bureau of Statistics Website) Figure 2: Australian Investment Abroad, 31 December 2005 (Source: Australian Bureau of Statistics Website) 19 Research Project in International Finance: 2007 Dang H Pham Effect of trading and FDI on PPP The PPP theory assumes the law of one price in an efficient international trade market as the fundamental conditions for a parity relationship (The law of one price works) Reasonably, the higher trade levels imply a more efficient market then the better PPP we can expect This research paper also examines the effect of trading between Australia and its trading partners from 1984 to 2005 on their PPP FDI also represents the capital mobility effect; however, FDI is very different from the portfolio capital investment in that it normally goes with the increase of trade and less liquidity Therefore, we expect that FDI may have positive effect on PPP This research will also make an effort to test the effect of FDI on PPP Results are reported in Table below Table Present results of regression PPP deviation against trade and FDI Since we can collect more data on trade than FDI, effect of trade on PPP is separately tested using data from 1984-2005 The result shows that relative trading level significantly (at 5%) increase the PPP Then we examine effects of trade and FDI on PPP using data from 1992-2003 We find no significant results However, the sign of coefficients show that all trade and FDI seem to increase the PPP Data Period Trade FDI -0.09 1984-2005 NA -0.09 1992-2003 ( 2.2 )* -0.006 ( 1.22 ) ( 0.45 ) * Significant at 5% Results in Table are obtained when PPP deviations are regressed against the trade weights level from 1984 to 2005 using Pooled cross-sectional data for all 12 countries together The negative significant at 5% of trade factor indicates that relative trade level does decrease the PPP deviation In other words, relative trade levels significantly increase the level of PPP We can not collect enough FDI data for the full range of our study period In fact, the data are only available from 1992-2003 (UNCTAD database) Hence, we test the 20 Research Project in International Finance: 2007 Dang H Pham effect of trade and investment in a multivariate regression using data only from 19922003 Results from this test are not significant for all trade level and FDI This could be due to the lack of data for our long-run PPP study However, the sign of the coefficients of trade and FDI indicate that FDI seems to have positive impact on the PPP 21 Research Project in International Finance: 2007 Dang H Pham VI CONCLUSION Empirical studies so far still hold inconclusive view on the existence of PPP in the real world even for the long-run Some issue relating to testing PPP remains a puzzle We test the PPP between Australia and its 12 trading partners for the period from 1984 to 2006 The results reject PPP for countries when we use CPI changes as proxy for inflation rates However, when PPI is used instead, PPP is rejected for only countries with 5% significance level The domination of trading in industrial goods market, to some extent, explains why PPP holds better with PPI In country specific level, we find that PPP hold better with CPI for some countries (New Zealand, Canada) Other countries show better PPP with PPI The same competitive advantages of New Zealand and Canada explain that abnormal results Investigation on the effect of level of trade on PPP deviation reports that trading decrease the level of PPP deviation or, in the other words, increases PPP This effect is found significant at 5% FDI seem to have positive effect on the level of PPP where our evidence shows a negative sign against PPP deviations but far to be significant We suggest that the insignificant result for FDI may have its reason in the shortage of Data which allows us to conduct the test only from 1992-2003, too short for a long-run PPP test 22 Research Project in International Finance: 2007 Dang H Pham VII FUTURE RESEARCH DIRECTIONS Since PPP is known theoretically to be affected by many other factors such as the transaction costs, the difference in levels of income, portfolio capital investment activities, and further studies could improve the results by doing more comprehensive test on the effect of those factors on the level of PPP Consumer goods markets often imply the country specific cultural characteristic, thus income cases consumer goods in one market can not be used in other market In that case the law of one price hardly works well in practice Take Japan consumer goods market for example, there are a lot of consumer products that are produced uniquely for the Japanese market and can not be use outside Japan Therefore, future studies on PPP can be interesting to model the cultural factors 23 Research Project in International Finance: 2007 Dang H Pham References Adler, M and Lehman, B (1983) Deviations from Purchasing Power Parity in the Long Run Journal of Finance 38
