A value for multichoice games

2000

Abstract A multichoice game is a generalization of a cooperative TU game in which each player has several activity levels. We study the solution for these games proposed by Van Den Nouweland et al. (1995) [Van Den Nouweland, A., Potters, J., Tijs, S., Zarzuelo, J.M., 1995. Cores and related solution concepts for multi-choice games. ZOR-Mathematical Methods of Operations Research 41, 289–311]. We show that this solution applied to the discrete cost sharing model coincides with the Aumann-Shapley method proposed by Moulin (1995) [Moulin, H., 1995. On additive methods to share joint costs. The Japanese Economic Review 46, 303–332]. Also, we show that the Aumann-Shapley value for continuum game…

The public sector's roles in the sharing economy and the implications for public values

2019

Abstract Motivated by the growing significance of the sharing economy, we discuss the roles the public sector may play within the sharing economy and the corresponding implications for public values. The sharing economy represents a transformative agent for the public sector within the current landscape of digital transformation. While the public sector has so far acted mainly as a regulatory body in the sharing economy, we here discuss implications for other roles the public sector may take on, including the roles of customer, service provider, and platform provider. Framed within the context of the public value ideals (professional, efficiency, service, and engagement), we examine the opp…

Existence of competitive equilibrium in a non-optimal one-sector economy without conditions on the distorted marginal product of capital

2012

Abstract This paper develops a method for proving the existence of competitive equilibrium in a distorted/non-optimal one-sector economy–a discrete time variant of the Romer model–without conditions on the equilibrium value of the marginal product of capital. Existence is obtained under weaker conditions than in Le Van et al. (2002) . Moreover, we provide an existence result for an economy with a regressive tax studied in Santos (2002) . The proofs rely on ideas of Becker and Boyd (1997) .

More Choice for Better Choosers: Political Freedom, Autonomy, and Happiness

2016

A substantial literature finds that freedom in the sense of an expanded opportunity set is positively related to happiness. A contrasting literature, however, finds that an excess of choice can have socially undesirable outcomes. We test the effect of two types of freedom—autonomy and political—on happiness using five waves of World Values Survey data (1981–2008). We find evidence supporting the claim that equipping people with the tools to direct the course of their lives (i.e. increasing autonomy freedom) incentivizes the desire to investigate alternatives (e.g. political parties) before making a decision. The effect of freedoms on happiness is diminished in contexts where individuals hav…

Abstract Public Service Platforms (PSPs) are a new type of technology platform. They are based in the philosophy of New Public Management (NPM) and support public services for citizens in quasi-markets. This article increases our understanding of the business models behind these PSPs in terms of their Value Propositions, structures, networks, and financing. We interviewed representatives from 14 PSP providers in four public sectors in Sweden: education, healthcare, elder care, and public pensions. We identified a “Traditional view” with its focus on public agencies and neutral information and an “Emerging view” that includes dialogues, user evaluations, long-term perspectives on choice, pro…

Zero viscosity limit of the Oseen equations in a channel

2001

Oseen equations in the channel are considered. We give an explicit solution formula in terms of the inverse heat operators and of projection operators. This solution formula is used for the analysis of the behavior of the Oseen equations in the zero viscosity limit. We prove that the solution of Oseen equations converges in W1,2 to the solution of the linearized Euler equations outside the boundary layer and to the solution of the linearized Prandtl equations inside the boundary layer. © 2001 Society for Industrial and Applied Mathematics.

Primary and secondary distributions after a small-amplitude potential step at disk electrode coated with conducting film

2011

Abstract The set of equations and boundary conditions for the “primary potential/current distribution” after a small-amplitude potential step has been analyzed for a film-coated disk electrode in contact with an electrolyte. The solution of these equations provides the overall short-time resistance of this system, Rtot, which is determined by the short-time resistance of the electrolyte solution in contact with the bare disk electrode, Rs, and the short-time film resistance to the current passage in the normal direction, R f = L f / κ f π r o 2 (ro, disk radius; Lf, film thickness; κf, its specific conductivity). The deviation of Rtot from the sum of these resistances, Rs + Rf, originates f…

Modified Landau levels, damped harmonic oscillator and two-dimensional pseudo-bosons

2010

In a series of recent papers one of us has analyzed in some details a class of elementary excitations called {\em pseudo-bosons}. They arise from a special deformation of the canonical commutation relation $[a,a^\dagger]=\1$, which is replaced by $[a,b]=\1$, with $b$ not necessarily equal to $a^\dagger$. Here, after a two-dimensional extension of the general framework, we apply the theory to a generalized version of the two-dimensional Hamiltonian describing Landau levels. Moreover, for this system, we discuss coherent states and we deduce a resolution of the identity. We also consider a different class of examples arising from a classical system, i.e. a damped harmonic oscillator.

WORKING CAPITAL AS AN ENTERPRISE VALUE ASSESSMENT TOOL

2019

The valuation of an entity in off-exchange transactions involves the use of different techniques. Nevertheless, none of them guarantees the most accurate result. Therefore, it is very difficult to choose one evaluation method. Both investors, corporate managers, financial professionals, portfolio managers, and securities analysts should have a basic understanding of the process of evaluating companies. To that end, professionals recommend evaluating a company’s financial reports to detect its financial position and solvency. According to the methods of financial analysis, working capital is one of the solvency ratios, which describes the value of resources that remain after the company’s cu…

Notional defined contributions (NDC): Solvency and risk in Spain

2007

The aim of this article is twofold: to demonstrate the actuarial imbalance in the Spanish pension system in its current form; and to measure the degree of aggregate economic risk to which pensioners are exposed when applying formulas for the calculation of retirement pensions based on notional accounts. The model used generates scenarios for various periods encompassing some 10,000 different permutations of the macroeconomic indices needed to calculate such parameters as initial pension, earnings replacement rate, or internal rate of return and value at risk. The findings are analysed both objectively and subjectively. The main conclusions are that if the projections for the macroeconomic i…
