Founded in 1997, the Department of Economics is among the founding departments of our University. The Department offers two extensive undergraduate programs, either in English or in Turkish. Our undergraduate programs are catered to developing our students’ skills of analytical thinking, and to practical education. In this regard, the Social Sciences Research and Training Laboratory, founded under the guidance of our department, offers hands-on training to our own students, students and academicians from other universities, and public institutions. Our Department also offers a Graduate Degree Program in Applied Economy and a Doctorate Degree Program in Political Economy for graduates of undergraduate and graduate degree programs.

Abstract

Recent research suggests that policies implementing structural change are required to alter the paths of carbon dioxide emissions in many nations. This note provides additional support for this view, allowing for smooth shifts in the deterministic part of the stochastic process. A Fourier wavelet unit root test indicates that in many countries, a temporary shock to emissions will have a permanent impact, whereas tests that examine fractional integration around a smooth break with de-trending indicate that a shock to emissions will have a transitory impact. Policies that induce structural changes are required to place emissions on a downward path.
