“…The long-run net MIRR was found to be 17.90 per cent, which is rather less than 26 per cent gross MIRR derived by Khatri (1994) using the twostage approach. However, both are far more reasonable than the very high earlier estimates, such as those of Thirtle and Bottomley (1989), which were based on shorter series and poorer data. Estimating the returns separately, for the pre and post Common Market eras, from 1953Market eras, from -1972Market eras, from and 1973Market eras, from -1990 gives returns of 18.56 per cent and 17.32 per cent respectively.…”

“…The conditioning factors are improvements on the series used by Thirtle and Bottomley (1989) and found by Khatri (1994) to be Granger-prior to productivity growth. Since it is not possible to include any significant number of lagged R&D terms in the profit function, a research knowledge stock was constructed, with the lag length and shape predetermined using the two stage approach in which the conditioning factors are taken to explain total factor productivity.…”

“…The lack of data limited the tests that could be performed, so the results should be treated with caution, but it does seem that short and long lags are just as important as those of four to seven years, which is when the peak effect should be found, according to conventional wisdom. The inverted U-shaped polynomial lags and the alternative lag structures used in the returns to R&D literature (see Thirtle and Bottomley, 1989) seem to fit these data poorly. We return to this problem after testing the pooled sample, in the next section.…”

“…The fixed factors, such as land, are treated as having a rental price for the service flow they produce. In the second stage of this approach, TFF' changes are explained by the determining variables in the E vector (see Thirtle and Bottomley, 1989).…”
