....rate (including persons in programs) instead of the open does not either effect the estimation results. 16 For a description of this test see Charemza and Deadman (1997, p. 66 67) 17 For a description of the procedure for testing the equality of two regression coefficients, see e.g. Gujarati (1995, pp. 254 255) Our estimated t value is 0.0025 and we can therefore not reject the null hypothesis that the two coefficients are of equal size. 18 Including the intercept in Model E makes virtually no difference to the equation. The value of the intercept is 0.003 and it s t value is 0.358. ....

Gujarati (1995, pp. 420 425) also has a description of the test procedure. 21 The test indicates no signs of serial correlation. We conclude that serial correlation is not a serious problem in the model. ....

....correlation. The fact that m 1 is highly significant for the OLS estimation is worrying as the t tests will no longer be valid. If the t tests are still used in the presence of (first order) serial correlation, this may lead to the wrong conclusions about the significance of the coefficients (Gujarati 1995, p.411) Insert table 4 about here. Table 4 investigates the impact of financing needs on investment spending with financing needs being defined as a company issuing new equity, reducing dividend payments, omitting dividends 20 , suffering from financially distress (filing for bankruptcy) ....

....across each cross section, with a fixed effects model (Hall, 1996) Both the F test and the Hausman specification test indicate that the fixed effects model is appropriate for all five models 8 reported below. Graphical analysis of the residuals for each model as suggested by Sayrs (1989) and Gujarati (1988) indicate no serious problems with heteroskedasticity or autocorrelation. FINDINGS The results of the pooled time series analysis are presented in Table 1. The fatality rate suffered by children ages 0 5 years serves as the dependent variable for models 1 and 2, while the fatality rate sustained ....
