Scatter plots of search intensities and GDP. Gross domestic product: Linearly detrended data (i.e. a linear trend was subtracted from the original data). Search activity variables: The lags of GDP yielding the strongest correlation in the regressions of Table 2 were used in the scatter plots: \(I^{JS}_{t}\) and \(GDP_{t-1}\), \(I^{F}_{t}\) and \(GDP_{t-3}\), \(I^{EA}_{t}\) and \(GDP_{t-2}\), \(SP_{t}\) and \(GDP_{t-3}\). The red lines visualise the fitted linear relationship stemming from OLS regressions
