Public procurement:An introduction
No full textThe public sector represents about 40 to 45 per cent of many economies in the developed world in terms of spend on providing services and procuring from the private sector. Internationally there are outliers, such as Singapore, where it is only about 18 per cent of the economy, and some of the African nations where, as nationalized industries are still prevalent, it can be as much as 80 per cent. Imagine how much might be saved and reinvested in public service provision if the spending bill was reduced by just 1 per cent in any nation. However, it is astonishing for such a vital, significant part of all nations’ economies that so little research has been conducted on public procurement across nations and even within nations to improve procurement to deliver these benefits
Challenges facing public procurement
No full textThe International Research Study of Public Procurement (IRSPP) was an idea that turned into a reality, representing one of the most significant contributions to public procurement research and practice. This first phase of the study saw academics and practitioners from around the world joining to ask each other ‘why’ and ‘how’. We entered the study not knowing what might be achieved and whether there was any long-term benefit of working across nations on something that might be quite specific to individual countries. Getting into and understanding the detail in each country, in different parts of the public sector, was a massive task given the vast amount of data we generated. However, it gradually became evident from that detail that different nations were adopting different approaches to public procurement. This first study enabled two very important deliverables – first, the network of people around the world and, second, a new framework for classifying public procurement
Quantitative analysis of strategic and tactical purchasing decisions
Get PDFPurchasing management is a relatively new scientific research field, partly due to the fact that purchasing has only recently been recognized as a factor of strategic importance to an organization. In this thesis, the author focuses on a selection of strategic and tactical purchasing decision problems. New quantitative models are developed for these decision problems using a range of mathematical techniques, thereby contributing to the further development of purchasing theory and its appliation in practice.The selected purchasing decision problems are:-ROI improvement drivers from a purchasing perspective-allocation of cost savings in a purchasing consortium-strategies for tendering procedures-fixed-price contracts versus spot market buying-supplier switching strategies for single sourcing-electronic procurement roll-out strategie
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Performance-based contracting in public procurement of developing countries
Get PDFThis research is focused on the application of Performance-based Contracting (PBC) in public procurement system of developing countries. We define five research objectives (ROs) that focus on this common issue. The first objective (RO1) mainly deals with the theory behind and the theoretical knowledge of PBC aspects. More specifically, it analyzes the concept and definitions of PBC by different authors, analyze the relevant theories in relation to PBC, and explore advantages and disadvantages of PBC in public procurement, specifically in the context of developing countries. In the subsequent research objectives (RO2-RO5), we focus on understanding the extent of the application of PBC and comparing it with the traditional contracting system, and we clarify the factors underlying the low use of PBC in the public procurement system of developing countries (RO2), the extent to which the application of PBC can minimize the existing challenges of public procurement in developing countries (RO3), to what extent PBC concepts are included in the rules and regulations of some selected international institutions and countries (RO4), and the perceptions of public officials on the application of PBC in the public procurement system (RO5). The findings of the research indicate that PBC is becoming an important instrument for the efficiency of public procurement, minimize the existing problems in the traditional procurement system, and achieve value of public money in general. Despite numerous benefits of PBC, application of it in the public procurement system is still limited. This is due to lack of clear legal framework, capacity and fear of corruption. Based upon these findings, we conclude this study with some suggestions to improve the applicability of performance-based contracting in the public procurement system of developing countries, taking Ethiopia as an example
