We propose marginal integration estimation and testing methods for the coefficients of varying coefficient multivariate regression model. Asymptotic distribution theory is developed for the estimation method which enjoys the same rate of convergence as univariate function estimation. For the...

In the present world where education is considered an important factor, all educational institutions are facing competition at a higher level. Students are diverted towards doing higher courses offered by numerous institutes, universities, and colleges, however with the increase in the number of...

There is still little consensus on the effectiveness of business support policies. The empirical evaluation is complicated by the difficulty in achieving reliable identification. We analyse the impact of Law 488/92, the main Italian regional policy. We propose a new approach, named multiple...

Energy is a fundamental factor in economic development. Although in recent years there is a development in studies on an energy economics they are focused on specific energy sources. In this study natural gas, electricity and oil consumption which are the energy sources that the greatest market...
