Non-linear adjustment of real wages,employment and output in the UK

We employ the Brock, Dechert and Scheinkman statistic to investigate non-linearity in conditional mean in UK real wages, employment and output, and to fit threshould regression models to the series. The latter porvide reasonable representations for thenon-lineraity in real wages and output but the residuals from the threshold autoregressive model for employment still contain a non-linear component. In a forecast comparison the TAR models performed better than simple autoregressions. Using the lagged share of wages as an error-correction term we find evidence that all three series respond asymmetrically to lagged changes in wage share and other variables. Fore-casts of real wages and employment derived from these models were superior to those derived from standard, symmetric, ECMs.

The hypothesis is rejected for the government's popularity but the results for individual party support are less clear out.
