TL;DR: In this article, the authors compare the performance of purchasing power parity (PPP) in the United States and its major trading partners during the Bretton-woods and flexible exchange rate periods.
Abstract: Real exchange rates between the United States and its major trading partners were calculated for the Bretton Woods and flexible exchange rate periods. Unit root tests indicate that Purchasing Power Parity performed poorly in both periods. Tests for cointegration reveal limited instances in which it is possible to estimate the deviations from PPP as an error correcting model. The estimated error correcting models indicate that foreign, but not U.S., prices responded to deviations from PPP. Frenkel's (1981b) finding that Purchasing Power Parity (PPP) worked better during the 1920s than the 1970s caused considerable controversy. For example, Davutyan and Pippenger (1985) contend that the socalled "collapse" of PPP is a result of an increase in the relative importance of real versus monetary shocks. They argue that the 1970s, as opposed to the 1920s, was characterized by real supply shocks and the international coordination of monetary policies. The argument is that PPP did not fail; rather, there was an increase in the volatility of those factors giving rise to deviations from PPP. Hakkio (1984) reestimated PPP over the 1920s and 1970s; using cross-country tests (i.e., SURE estimates) to improve the efficiency of his estimates, he was able to support the hypothesis that PPP worked better in the 1970s than in the 1920s. On the other hand, papers by Adler and Lehman (1983), Dornbusch (1980), Frenkel (1981a), Junge (1985), and Krugman (1978) report findings contrary to the PPP hypothesis. Moreover, Kenen and Rodrik (1986) find that the volatility of real exchange rates has increased throughout the flexible rate period. This paper tries to shed some light on the importance and persistence of the observed deviations from Purchasing Power Parity under alternative exchange rate systems. While it is interesting to compare PPP in the 1920s versus the 1970s, it is equally useful to compare the 1960s versus the 1970s and 1980s. If real supply shocks and lack of monetary coordination are characteristic of the latter period, PPP should perform better in the 1960s. To illustrate the issues involved, consider the following econometric model of (Relative) Purchasing Power

TL;DR: In this paper, the authors investigated whether there is a relationship between international trade and international travel flows using time series econometric techniques and found support for prior beliefs that international travel and international trade leads to international trade.
Abstract: This paper investigates, for the first time, whether there is a relationship between international trade and international travel flows using time series econometric techniques. Using data for Australia and four important travel and trading partners, the USA, the UK, NZ and Japan, the paper tests three specific hypotheses: that business travel leads to international trade; that international trade leads to international travel; and that international travel, other than business travel, leads to international trade. Using cointegration and Granger-causality approaches the paper finds support for prior beliefs that there is a relationship between international travel and international trade, and suggests that this may be a fruitful area for further research.

TL;DR: In this article, Toda et al. investigated the dynamic causal linkages among nine major international stock price indexes and found significant interdependencies between the established OECD and Asian markets, and also the leadership of the US and UK markets over the short and long run.

TL;DR: In this article, a stochastic cointegration model for quantile regression with cointegrated time series is proposed, where the value of cointegrating co-efficients may be aected by the shocks and thus may vary over the innovation quantile.

TL;DR: This article examined long-run relationships and short-run dynamic causal linkages among the U.S., Japanese, and ten Asian emerging stock markets, with the particular attention to the 1997-1998 Asian financial crisis.
Abstract: This study examines long-run relationships and short-run dynamic causal linkages among the U.S., Japanese, and ten Asian emerging stock markets, with the particular attention to the 1997-1998 Asian financial crisis. Extending related empirical studies, comparative analyses of pre-crisis, crisis, and post-crisis periods are conducted to comprehensively evaluate how stock market integration is affected by financial crises. In general, the results for the case of Asia show that both long-run cointegration relationships and short-run causal linkages among these markets were strengthened during the crisis and that these markets have generally been more integrated after the crisis than before the crisis. Detailed country-by-country analyses are provided, which yield a variety of new results concerning the roles of individual countries in international stock market integration. An important implication of our findings is that the degree of integration among countries tends to change over time, especially around periods marked by financial crises.
