The private and public correlation cost of three random variables with collaboration

© 2016 IEEE. In this paper, we consider the problem of generating arbitrary three-party correlations from a combination of public and secret correlations. Two parties - called Alice and Bob - share perfectly correlated bits that are secret from a collaborating third party, Charlie. At the same time, all three parties have access to a separate source of correlated bits, and their goal is to convert these two resources into multiple copies of some given tripartite distribution ℙ(XYZ). We obtain a single-letter characterization of the tradeoff between public and private bits that are needed to achieve this task. The rate of private bits is shown to generalize Wyner's classic notion of common information held between a pair of random variables. The problem we consider can be contrasted fruitfully with the task of secrecy formation, in which ℙ(XYZ) is generated using public communication and local randomness but with Charlie functioning as an adversary instead of a collaborator. We describe in detail the differences between the collaborative and adversarial scenarios

Heterogeneity in R&D cooperation: an empirical investigation

This work explores the roles of potential simultaneity and heterogeneity in determining firms' decisions to engage in R&D collaboration, using a sample of Italian manufacturing firms. Partnerships with other firms, research institutions, universities and other small centres are considered jointly by applying a multivariate probit specification. This allows for systematic correlations among different cooperation choices. The results support the hypothesis that the four cooperation decisions are interdependent. The decision to cooperate in R&D differs significantly depending on the cooperation options. Public support, the researcher intensity and the size are all of importance in determining R&D alliance strategies

How do public programmes shape strategic R&D collaborations? Project-level evidence from the 5th and 6th EU Framework Programmes.

We analyze the micro rationale of EU-sponsored collaborations compared to non-sponsored, spontaneous collaborations. We compare the incentives and coordination mechanisms of each type of collaboration, and derive propositions that we test empirically. Our econometric analysis uses recent data on (sponsored and non-sponsored) projects conducted by participants in the 5th and 6th European R&D Framework Programmes. Our empirical findings support our main propositions. Compared to spontaneous collaborations, EU-sponsored collaborations clearly have different characteristics and follow a different rationale. However, there is no major difference between the different types of EU-sponsored collaborations.Strategic R&D Collaborations; European Framework Programmes; Research Joint Ventures.

Enhancing Coastal Resilience: Perspectives on Valuing RI Coastal Lands

This paper discusses coastal resilience as an organizing framework for future policymaking, coastal planning, and insurance decisions, and explores the different perspectives of the value of ecosystems held by various stakeholders in Rhode Island’s coastal communities. A grounded theory approach was used in an effort to abstract general insights from the substantive but isolated areas of coastal management and economics. Special attention is given to the perspectives of municipal decision makers, the National Flood Insurance Program, natural economists, and real estate developers. We have (1) conducted a statistical analysis of environmental spending of RI towns, (2) identified key models for ecosystem services valuation, (3) researched the major threats to coastal ecosystems, and (4) explored how the coastal resilience theme might shape the future of the coast. Elements of the study rely on the formulation and testing of hypotheses. However, the analysis was primarily a demonstration of the inter-disciplinary emergent thinking that this paper proposes will provide solutions for coastal communities’ most pressing issues. The framing question is how social, personal, and environmental goals align when coastal resilience is enhanced, and how stakeholders can utilize these new decision-making tools to achieve increased communication and a more accurate understanding of the perceived value of ecosystem services

Choosing international organizations: when do states and the World Bank collaborate on environmental projects?

While international cooperation research emphasizes institutional design, states mostly interact with existing organizations. How do states choose organizations for cooperation? We develop a theory of agency choice for development projects, emphasizing the importance of domestic institutions, the scope of cooperation, and the resources of the implementing agency. If states are to cooperate with funding agencies that have abundant resources, such as the World Bank, they must accept more stringent conditions on project implementation. We argue states accept the stringent conditions that resourceful organizations demand if the public goods from project implementation are highly valuable. Empirically, this is the case for democratic states, large projects, and projects that produce national instead of global public goods. We test this theory using data on 2,882 Global Environment Facility (GEF) projects, 1991–2011. The GEF offers an ideal case because various implementing agencies are responsible for the actual projects. States implement projects in collaboration with the World Bank, which has the most expertise and resources among the GEF’s implementing agencies, if their regime type is democracy, the project size is large, and the benefits are primarily national. Qualitative evidence sheds light on causal mechanisms

Repeated Rounds with Price Feedback in Experimental Auction Valuation: An Adversarial Collaboration

It is generally thought that market outcomes are improved with the provision of market information. As a result, the use of repeated rounds with price feedback has become standard practice in the applied experimental auction valuation literature. We conducted two experiments to determine how rationally subjects behave with and without price feedback in a second price auction. Results from an auction for lotteries show that subjects exposed to price feedback are significantly more likely to commit preference reversals. However, this irrationality diminishes in later rounds. Results from an induced value auction indicate that price feedback caused greater deviations from the Nash equilibrium bidding strategy. Our results suggest that while bidding on the same item repeatedly improves auction outcomes, this improvement is not the result of price feedback

Impact analysis of technological public services supplied to local firms: a methodology

The aim of this work is to present a methodology useful to verify the impact of public interventions directed to support the technological innovation in local groups of SMEs. In the last decades, in several agglomerations of firms, some difficulties emerged, related to the small-medium enterprises gaps in innovation, to their low competitiveness and to the rising of distinct historical heritages in specific areas. To overcome them, some public interventions have been put into place, aimed at supporting the local units’ development, and at sustaining the growth of the area. The work examines two central points of this mechanism. Is it possible to evaluate the effects and the utility of the above mentioned public actions on the involved SMEs? Which is the methodology that is appropriate for such an evaluation? In the economic literature these questions are linked to the “evaluation problem”. This work suggests four methodologies (statistical - descriptive analysis and the application of regression, Probit and difference in difference models) to achieve these targets and, before that, it discusses the type of data that should be collected to apply them.Firms’ Technological Innovation, Public interventions evaluation, Impact analysis methodologies
