What transforms a desirable project on a government wish list to an attractive investment opportunity in the eyes of a potential private sector partner? This guide seeks to enhance the chances of developing effective partnerships between the public and the private sectors by addressing one of the main obstacles to the effective delivery of public-private partnership (PPP) projects: having the right information on the right project for the right partners at the right time. Data from the World Bank and the Public-Private Infrastructure Advisory Facility (PPIAF) private participation in infrastructure (PPI) project database indicate that private sector investment in infrastructure in developing economies grew steadily over the past decade. By 2007 the levels had finally surpassed the peak levels seen in 1997, the end of the previous growth spurt. This guide focuses specifically on what should be done, and when, in order to prepare projects to attract the right long-term private partners, procure their involvement, and manage the partnership. This guide is not a detailed project preparation manual; rather, it seeks to provide an overview of the process and what is involved so that greater realism can be applied to this challenging task and adequate resource plans can be developed.

As growth and development in Africa increase rapidly, investment in infrastructure projects will often be best accomplished through public-private partnership. This Project Preparation Guide offers the foundation blocks for public sector engagement with the private sector. This book assesses the relevant issues for selecting a project for public-private partnership, the actions for preparing projects for market, and the management process The guide addresses hiring and managing expert advisers, explains how the public sector should interact with the private sector during the project selection and preparation phases to ensure that decisions during these phases are realistic, and analyzes the issues of engagement with the private sector during the tender and after a contract has been signed. 'Attracting Investor to African Public-Private Partnerships' will help the public sector in Africa to attract private sector investment through effective project advertising, management, and implementation. This book will enhance the chances of developing effective public-private partnerships by overcoming major obstacles to project delivery by having the right information, on the right projects, for the right partners, at the right time. This guide is aimed at African public sector officials who are concerned about the delivery of infrastructure projects and services through partnership with the private sector, as well as staff in donor institutions who are looking to support PPP programs at the country-level.

This book aims to help governments and public authorities to establish effective light rail-light metro transit (LRMT) systems, and focuses on use of Public-Private Participation (PPP) arrangements. Rather than identify a single approach, authors present options and discuss practical issues related to preparing and implementing new LRMT PPP schemes. The approach is focused on providing information that can be used to make informed decisions, adapted to local policy and objectives. The material presented is intended as a practical guide to developing LRMT PPPs in both developed and developing countries. This work endeavors to provide answers to readers' questions regarding how to successfully incorporate private sector participation in LRMT with a lesser emphasis on why LRMT and the private sector may be beneficial. The primary focus of this text is guiding the reader from design through to project implementation. It starts from the premise that underlying transport policy decisions will have already been made and that LRMT has already been identified as the appropriate transport solution. The authors have included some limited discussion of policy and technical issues where these directly impact the LRMT PPP approach. The approach is presented in nine sections, and in preparing it the author drew on current international LRMT PPP experience, through a series of interviews and case studies. The sections covered are: 1) urban transport and LRMT: an overview of urban transport policy, the characteristics of LRMT schemes and the influences on LRMT policies; 2) technical issues: a brief review of some key technical issues inherent in LRMT schemes and their potential impact on PPP design and implementation; 3) incorporating private sector participation in LRMT initiatives: what PPP has to offer, and an overview of the issues and stages public authorities follow to establish successful LRMT PPP arrangements; 4) understanding and managing risk: analyzing and allocating risks and responsibilities among stakeholders in the LRMT scheme and practical ways of designing risk allocation rules; 5) PPP, design, specifications and performance management: setting service standards and specifications and establishing associated costs; developing of performance and payment indicators and managing compliance; 6) funding and finance: large LRMT capital and system maintenance requirements require strong financing arrangements. The practical use of public and private financing mechanisms under PPP arrangement is reviewed; 7) developing a PPP agreement: looking at the main types of PPP agreements, an outline framework for developing the contractual arrangement is developed through re-view of key issues; 8) procurement: reviewing the approaches that the public authority can use to select the private partner; and 9) conclusions.

This book reviews the major developments in and the lessons learned from the 21-year (1991-2012) experience with private sector participation (PSP) in the power sector in India. It discusses the political economy context of the policy changes, looks at reform initiatives that were implemented for the generation sector, describes transmission and distribution segments at different points in the evolution of the sector, and concludes with a summary of lessons learned and a suggested way forward. The evolution of private participation in the Indian power sector can be divided into different phases. Phase one was launched with the opening of the generation sector to private investment in 1991. Phase two soon followed - early experiments with state-level unbundling and other reform initiatives, including regulatory reform, culminating in divestiture, and privatization in Orissa and Delhi respectively. Phase three, the passage of the electricity act of 2003 by the central government, followed by a large increase in private entry into generation and forays into transmission and experiments with distribution franchise models in urban and rural areas during the 11th five-year plan (2007-12) period. In phase four, at the start of the 12th five-year plan (2012-17), the sector is seeing a sharp reduction in bid euphoria and greater risk aversion on the part of bidders, who are concerned about access to basic inputs such as fuel and land. In this context, the report is structured as follows: chapter one gives introduction; chapter two presents private sector participation in thermal generation; chapter three presents private sector participation in transmission; chapter four deals with private sector participation in distribution; chapter five deals with private sector participation in the Indian solar energy sector; chapter six deals with financing of the power sector; chapter seven presents emerging issues and proposed approaches for the Indian power sector; and chapter eight give updates.

Ateniese et al. (PKC 2011) introduced the concept of size-hiding private set intersection (SHI-PSI) and proposed a construction for two parties. The SHI-PSI protocol protects the privacy of input set content and better guarantees the privacy of the client set size. However, more practical protocols in multi-party scenarios have remained a research gap. In this paper, we propose a secure and feasible protocol named size-hiding multi-party private set intersection . Based on the Bloom filter, threshold homomorphic encryption and marking technique, the proposed protocol supports the private set intersection among multiple participants. Meanwhile, the set size privacy of the designated participant is preserved. The proposed protocol is proved to be secure against semi-honest participants under the decisional composite residuosity assumption. Finally, the efficiency of our protocol is illustrated through both performance analyses and comparisons of related work.

This article presents a longitudinal comparative analysis of the regulation of private funding to political parties in 15 West European democracies and explores how these rules have changed under the most recent wave of political finance reforms. In particular, the article questions whether a deregulation of political finance regulation may be in sight, with a downsizing of the role of the state in the political finance domain. While evidence does not support a clear movement toward deregulation, the article shows that the move from private to public subsidization may not be that irreversible as it seemed and that private funding to political parties is likely to become more prominent in the near future also in Europe.

Purpose Low income urban housing in Kenya is underdeveloped as a result of uninnovative financing, hence the many slums and informal settlements in the country, hence the need for enhanced participation of the private sector through application of Public Private Partnerships (PPPs), which has been cited as one of the possible solutions. The purpose of this study was to investigate and make predictions of the need for enhanced role of private sector in developing low income urban housing in Kenya through PPPs. Design/methodology/approach Delphi method of research was used to forecast the enhanced role of private sector through PPPs in the development of low income urban housing in Kenya. Three rounds Delphi iterations using three panels of housing financiers (30 in number), housing developers (28 in number) and housing practitioners (30 in number) were used. Data was collected through questionnaires throughout the three rounds, where the first round was exploratory in nature, the second round built on answers from round one, while round three was based on answers from round two, after which the mean and standard deviation values were calculated to show the level of consensus. Findings Results showed that PPPs is one of the plausible ways through which low income urban housing in Kenya can be developed to address its shortage. Private sector in PPP transaction brings innovative technology, finance and efficiency, while government brings its assets such as land and other regulations long term contracts. Research limitations/implications The research was focussed on the Nairobi city county area in analysing the need for enhanced role of the private parties. It focussed on a panel of Housing practitioners-officers in the State Department for housing and Nairobi city county; housing financiers and housing developers, without interviewing the beneficiaries of the method. Practical implications It was, therefore, found out that PPPs models are applicable in developing low income urban housing because the country has the enabling environment for its effective application going forward. The implication of this study is that low income urban housing can be developed through the model. Social implications The slums and informal settlements will have adequate, affordable and quality housing being introduced within their neighbourhoods, which reduces political and societal animosities. Originality/value This research has benefited from published literature on PPPs and original research on PPPs.

In this paper, we utilize d-dimensional Bell states to construct a multi-party semiquantum private comparison (MSQPC) protocol with two supervisors, which can determine the size relationship of more than two classical users’ private inputs under the control of two supervisors within one round implementation. The two supervisors, i.e., one quantum third party (TP) and one classical TP, are both semi-honest, which means that they can misbehave at their own wishes but are not permitted to conspire with anyone else. Neither quantum entanglement swapping nor unitary operations are required in the proposed MSQPC protocol. The security analysis certifies that the proposed MSQPC protocol can overcome both the outside attacks and the participant attacks.

In this paper, by utilizing d -dimensional single-particle states, three semiquantum cryptography protocols, i.e., the multi-party semiquantum private comparison (MSQPC) protocol, the multi-party semiquantum multiplication (MSQM) protocol and the multi-party semiquantum summation (MSQS) protocol, can be achieved simultaneously under the assistance of two semi-honest quantum third parties (TPs). Here, the proposed MSQPC scheme is the only protocol which is devoted to judging the size relationship of secret integers from more than two semiquantum participants without a pre-shared key. And the proposed MSQM protocol absorbs the innovative concept of semiquantumness into quantum multiplication for the first time, which can calculate the modulo d multiplication of private inputs from more than two semiquantum users. As for the proposed MSQS protocol, it is the only semiquantum summation protocol which aims to accomplish the modulo d addition of more than three semiquantum users’ private integers. Neither quantum entanglement swapping nor unitary operations are necessary in the three proposed protocols. The security analysis verifies in detail that both the external attacks and the internal attacks can be resisted in the three proposed protocols.
