Looking for a job is influenced by level of economic development and by new information technologies adoption. In this paper, an exploratory and cluster analysis, and a multiple regression analysis was applied when studying variable Y- Percentage of individuals using the Internet for looking for a job or sending a job application (individuals aged 16 to 74; average for 2004-2008) depending on six independent variables which are: X1-Level of Internet access in households (Percentage of households who have Internet access at home), X2- GDP per capita in PPS (GDP per capita in Purchasing Power Standards (PPS) (EU-27 = 100); X3- Total unemployment rate; X4- Public expenditure on education (Percent of GDP); X5- Individuals' level of computer skills (Individuals who have carried out 1 or 2 of the computer related. Percentage of the total number of individuals aged 16 to 74; X6 - A dummy variable for a country being in transition or not.
Data EU-27, Island, Turkey and Croatia were investigated.
Using multivariate analysis of data based on cluster analysis with n=30 countries and k=6 variables, Ward linkage and Euclidean distance, four clusters were created.
Since the multiple linear regression Model I with all six proposed regressors influencing the dependent variable Y showed that only variable X1 is statistically highly significant, but with multicollinearity problem, a smaller dimension final Model II with only K=2 regressors X1 and X2 was developed.
The F-test with p-value=5,75E-07 shows that the overall regression is statistically significant at 1% significance level. Coefficient of determination R2 shows that 65,5% of the total sum of squares is explained by the Model II explaining the variability in the dependent variable Y- Percentage of individuals using the Internet for looking for a job or sending a job application (percentage of individuals aged 16 to 74; average for period 2004-2008). Further, the regression diagnostics was conducted using the t test for testing the significance of each of the independent variables. The variable X1-Level of Internet access in households (Percentage of households who have Internet access at home) is highly statistically significant, and X2- GDP per capita in PPS (GDP per capita in Purchasing Power Standards (PPS) (EU-27 = 100) is significant at 7% significance level.
