Public R&D project portfolio selection problems under expenditure uncertainty and sectoral budget balancing

Çağlar, Musa
In this dissertation, we deal with the two issues that exist in the practice of public R&D funding program management. First one is the underutilization of the funding budget owing to several sources of expenditure uncertainty. Project cancellations and spending uncertainty of successfully completed projects cause to funding budget underutilization. In the first and second part of the dissertation, we propose new approaches to enhance the utilization of the total funding budget. Specifically, in the first part of the dissertation, we focus on incorporation of project cancellations into the decision making process. In the second part of the dissertation, we deal with stochastic modeling of the expenditures of both canceled and successfully completed projects. We showed that modeling those uncertainties can significantly improve the utilization of the funding budget. Increased public R&D budget utilization will help to support more R&D projects and hence achieve higher socio-economic impact. Second issue in the practice of R&D funding management is balancing of the total funding budget among sectors. In the third part of the dissertation, we deal with incorporation of sectoral impact assessment results into the decision making process to ensure sectoral budget balancing. We compare our proposed approach with some alternative policy options. We showed that proposed model enhances total impact of funding budget by keeping relative budget balancing among sectors.


Public R&D project portfolio selection problem with cancellations
ÇAĞLAR, Musa; Gürel, Sinan (Springer Science and Business Media LLC, 2017-07-01)
In this study, we address a public R&D project portfolio selection problem with project cancellations. For several reasons, a funded R&D project may be halted before finishing the planned research. When a project is canceled, most of its budget is usually unused and also some of the spendings can return to the funding organization. In the call-based R&D programs, usually project selection decisions are made in one go, and, in the current call, it is not possible to award new projects with the unused budget....
Analyzing the determinants of R&D, its impact on productivity and efficiency of firms in the Turkish Manufacturing Industry
Kalaycı, Elif; Pamukcu, Mehmet Teoman; Department of Science and Technology Policy Studies (2012)
This dissertation consists of three papers revolving around economics of R&D. The first paper analyzes the determinants of R&D expenditures with specific focus on foreign ownership and spillovers; the second paper studies the impact of R&D on productivity and the third paper analyzes whether conducting R&D enables Turkish manufacturing firms to catch up with sector leaders as far as their productivity levels are concerned. The first contribution of the thesis is the use of newly available data from Turkish ...
The Heuristic role of questions in the formation of research programmes: Copernicus’s heliocentric system
Altuğ, Sezen; Bağçe, Samet; Department of Philosophy (2016)
The aim of this thesis is to develop a critical view about the notion of the heuristic in Lakatos’s methodology of research programmes. The heuristic is tried to be sterilized from its defects with an insight derived from different forms of theories dealing with questions. For that reason, a short survey which includes Socratic dialogues, Hintikka’s theory of interrogative games, van Fraassen’s theory of why-questions, and Laudan’s analogy between science and problem-solving activity is introduced. As a res...
Impact analysis of industrial research and development subsidy programs in Turkey: an appraisal of quantitative approaches
Tandoğan, Vedat Sinan; Pamukcu, Mehmet Teoman; Department of Science and Technology Policy Studies (2011)
This thesis has two objectives in the field of policy evaluation that recently received extensive attention from international science and technology community. First, an attempt is made to examine, in the Turkish context, the effects of public subsidies on private research and development (R&D), selecting and implementing a suitable empirical methodology. Second, in the context of emerging economies, it aims to contribute to the existing impact analysis literature by providing an evaluation study for the p...
Factors limiting the effectiveness of EU grant projects: a case study of the ISEDP projects in Ankara
Yıldırım, Ümit; Ecevit, Fatma Yıldız; Department of Social Policy (2019)
The purpose of this thesis is to examine the effectiveness of EU funded ISEDP (Improving Social Integration and Employability of Disadvantaged Persons) grant scheme programs based in Ankara. Another subject of this work is also to examine the effectiveness of ISEDP grant schemes on the related policies’ improvement. Additionally, this thesis aims to understand what the fundamental reasons behind each projects’ outcome deviations are. Within the frame of development theory, the thesis analyzes the mentality ...
