[EN] This study aims to measure the welfare impact of the recent improvement in the duration of completion of the public investment projects in the Turkish economy. For this purpose, a real business cycle model is constructed in which the public capital is subject to a time-to-build constraint. The model is utilized to study a reform that mimics the recent Turkish experience, namely, shortening the completion duration to 4 years from roughly 9 years. The model implies that such a reform, when all the long-run effects are realized, leads to significant welfare gains corresponding to a 0.69 percent increase in consumption in all future states and time. These remarkable welfare gains are brought about by a higher economy-wide capital stock that is facilitated by an increased demand for public investment, and the accompanying upswing in the private investment.
