WebA non-linear test of causality using artificial neural networks. Two MLP artificial neural networks are evaluated to perform the test, one using just the target time series (ts1), and the second using both time series. The null hypothesis of this test is that the second time series does not cause the first one. Value gci: the Granger ...

WebDownloadable! xtgrangert performs the Half-Panel Jackknife (HPJ) Wald-type test for Granger non-causality, developed by Juodis, Karavias, and Sarafidis (Empirical Economics, 2024). This test offers superior size and power performance, which stems from the use of a pooled estimator with a (NT)^(1/2) rate of convergence. The test has two … Web2024:Q4, we test for Granger non-causality between banks’ profitability and cost efficiency. The null hypothesis is rejected in all cases, except for large banks during a period spanning the financial crisis (2007–2009) and prior to the introduction of the Dodd–Frank Act in 2011. This outcome may be conducive of past moral hazard-type
The Granger causality test is a statistical hypothesis test for determining whether one time series is useful in forecasting another, first proposed in 1969. Ordinarily, regressions reflect "mere" correlations, but Clive Granger argued that causality in economics could be tested for by measuring the ability to predict … See more We say that a variable X that evolves over time Granger-causes another evolving variable Y if predictions of the value of Y based on its own past values and on the past values of X are better than predictions of Y … See more If a time series is a stationary process, the test is performed using the level values of two (or more) variables.
