This paper proposes an alternative methodology to assess fiscal sustainability. Our balance-sheet approach (BSA) relies on estimating separately all of a government's assets and liabilities as opposed focusing only the burden explicit liabilities. In our approach, are primarily present discounted value taxes, include but also expenditures. Using liabilities, we compute balance sheet, therefore ...

In B2B contract enactment, cooperation should be taken into account when modeling contractual commitments through obligations. We advocate a directed deadline obligation approach, taking inspiration on international legislation over trade procedures. Our proposal is based on authorizations granted in specific states of an obligation lifecycle model. Flexible deadlines provide an additional leve...

This paper deals with the prediction of the amount of outstanding claims that an insurance company will pay in the near future. We consider various competing models using Bayesian theory and Markov chain Monte Carlo methods. Claim counts are used in order to add a further hierarchical stage in the usual log-normaland state-space models. By this way, we incorporate information from both the outs...

This paper adopts the economic organization framework to the study of industrial dynamics in an international context. We formulated the evolution of solar photovoltaic technology in terms of a stage-gated innovation cycle and studied the institutional requirements for the transition across different stages of development. The objective of organization of the industry, taken technology as given...

Studies investigating the question whether contractual and relational governance are substitutes or complements have been based on contradictory conceptualizations and have produced conflicting research results. This caused a controversial debate in the field of IS outsourcing concerning the relationship of governance mechanisms. Thus, the goal of this study is to clarify these inconsistencies....

This paper proposes a novel approach that draws upon the existing architecture and contractual relationships and compares the approach to the main existing techniques for securing BGP against prefix hijacking. We define prefix hijacking as usurping control of IP prefixes through the manipulation of BGP routing tables resulting in a redirection of network traffic away from a correct route to a p...

The existing problem in the construction industry, i.e. owner or client dissatisfaction in terms of prolonged delivery times, exceeded budgets and the non-attainment of quality standards. Real problems were substantiated by the emphasis on contractual responsibilities and risks. Construction investments are generally believed to be expensive. When contractual processes are in disarray, owners’ ...

This study reports on computational experiments for an agent-based labor market-model-with adaptive choice'and refusal of work site' partners and with endogenously evolving work site behaviors. Two treatment factors ^e experimentally varied: market structure; and ex ante capacity constraints on potential work offers and job openings.Particular attentions focused on experimentally determined cor...
