NettetThe Calgary, Vancouver, Toronto and Montreal markets drive the Canadian housing market, leading all cities toward long-run equilibrium. Strong long-run Granger causality exists, but the authors observe no instantaneous causality. Price information takes time to disseminate, and long-run price adjustments play a significant role in causation. Nettet20. apr. 2014 · The two possible types of dependence (dynamical and instantaneous) will be encoded in the graphs by two different types of edges between the vertices. Dynamical causality will be represented by an arrow, hence symbolizing directivity, whereas instantaneous coupling will be represented by a line. 3.2. A detailed example

Such a decomposition may be useful but it is clear that when instantaneous causality occurs, the measures of causal strength and phase lag will lose their meaning. It was noted in Section 3 that instantaneous causality models such as (5.2) in
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 the future values of a time series using prior values of another time series. Since the qu…
