17 Table 1 - Fixed and Random effects estimates and model specification tests for various OECD countries Hausman test Mundlak test LM test (pvalues) Country Timespan N. sectors 95% confidence interval (p-values) (p-values) BGT Test (pvalues) Fixed effects model Belgium Czech Finland Slovenia Sweden Random effects model Greece Notes. The Hausman test is distributed as a χ squared with 1 degree of freedom. Its null is that the random effects model is preferable to the fixed effects one. The same null has the Mundlak test which has an F distribution with degrees of freedom equal to the number of regressors and the number of observations minus twice the number of regressors plus one. The LM test is asymptotically distributed as a N(0,1) for the number of time periods going to infinity. See Baltagi (2001), pp Its null is the absence of serial correlation. For Greece only, the LM test is instead the one presented by Baltagi (2001), pp and it is asymptotically distributed as a χ squared with 2 degrees of freedom for the number of cross-sectional units going to infinity. Its null is the absence of serial correlation and that the variance component due to sectoral specificieties is equal to zero. The BGT test is the Burke, Godfrey and Termayne (1990) test illustrated by Baltagi (2001), pp It is asymptotically distributed as a N(0, 1) for a large number of sectors. Its null is that the error process of the estimated equation can be modelled as an AR(1) rather than an MA(1).

Of the seven cointegration tests, the panel v-statistic is a one-sided test where large positive values reject the null hypothesis of no cointegration, whereas large negative values for the remaining test statistics reject the null hypothesis of no cointegration. All the cointegration tests are carried out without including a trend. For lag selection in the cointegration tests we used the Schwarz information criterion. 1 percent significance level denoted by a.
