    1.1. Granger causality test 1.1.1. Pre-crisis period from 2005 to 2007 Since we aim to compare the causal relationship between stock price and exchange rate before and after the 2008 global financial crisis, we analyze the Granger causality test results in different subperiods separately first. Before the test, we use final prediction error (FPE) criterion to select lag orders. During the pre-crisis period from 2005 to 2007, an optimal lag length of one was selected for all the seven markets. The Granger causality test results for pre-crisis period are shown in table 4. Table 4 Granger causality test results for pre-crisis period from 2005 to 2007 Market Ho F-value Prob>F Coefficient P>|t| China ΔlnEXt≠>ΔlnSt 0.19 0.8233 ΔlnSt(-1) 0.973 ΔlnEXt(-1) 0.535 ΔlnSt≠>ΔlnEXt 0.10 0.9025 ΔlnSt(-1) 0.927 ΔlnEXt(-1) 0.662 Taiwan ΔlnEXt≠>ΔlnSt 3.20*** 0.0415 ΔlnSt(-1) 0.255 ΔlnEXt(-1) 0.065 ΔlnSt≠>ΔlnEXt 1.77 0.1714 ΔlnSt(-1) 0.214 ΔlnEXt(-1) 0.306 Singapore ΔlnEXt≠>ΔlnSt 5.55*** 0.0041…

    6.5 Granger Causality Granger causality statistics determine whether past values of one variable helps to predict another variable. For example, if the lagged value of the independent variable X, help in predicting the value of the explanatory variable Y_(t+1), then X granger causes the Y. On the other hand, if the independent variable X does not help to predict Y, then the coefficients on the lags of X will all be zero in the reduced form Y equation. 7. Empirical results 7.1 Optimal lag…

    The null hypothesis of this test is that the past p values of X are not helpful to predict Y (X does not Granger cause Y). The alternative hypothesis is that the past p values of X are useful to predict Y (X Granger causes Y). p is the lag length of the Granger causality test and the results of the test depend on the chosen lag lengths (p). Therefore, different lag lengths (6, 12, 18, 24, 30, 36 lag lengths) are used in this study. These lag lengths represent a three-year horizon. The following…

    It is important to note that Rowling lets Harry make mistakes and succumb to the temptation of using the Unforgivable Curses.
