Abstract:
Background: Valuation studies of preference-based health measures like SF6D have been conducted in many countries. However, the cost of conducting such studies in countries with small populations or low- and middle-income countries (LMICs) can be prohibitive. There is potential to use results from readily available countries’ valuations to produce better valuation estimates. Methods: Data from Lebanon and UK SF-6D value sets were analyzed, where values for 49 and 249 health states were extracted from samples of Lebanon and UK populations, respectively, using standard gamble techniques. A nonparametric Bayesian model was used to estimate a Lebanon value set using the UK data as informative priors. The resulting estimates were then compared to a Lebanon value set obtained using Lebanon data by itself via various prediction criterions. Results: The findings permit the UK evidence to contribute potential prior information to the Lebanon analysis by producing more precise valuation estimates than analyzing Lebanon data only under all criterions used. Conclusions: The positive findings suggest that existing valuation studies can be merged with a small valuation set in another country to produce value sets, thereby making own country value sets more attainable for LMICs.

Abstract:
The authors measured perceived quality of life for 4 disabilities among 450 adults in 3 resource-limited countries, measuring mean utilities using time trade-off, and surveying participants on 35 sociocultural characteristics to compare utilities for disabilities by country and examine associated sociocultural characteristics. Mean utilities were >0 for mild and moderate, but <0 for severe and profound. Utilities differed across countries ( P = .007, .000, .017, .000 for mild, moderate, severe, profound, respectively). Vietnamese utilities correlated with residence ( P = .03, moderate), education ( P = .03, severe), and number of children ( P = .03, moderate). Peruvian utilities correlated with education ( P = .05, mild; P = .05, severe), experience with disability ( P = .001, mild), gender ( P = .04, moderate; P = .03, profound), number of hospitalizations ( P = .04, severe). In Haiti, the only correlate was rejection ( P = .02, moderate). Culture-specific variables differentially shape perceptions of disability in developing countries, thereby affecting cost-effectiveness calculations. Given substantially negative perceptions, reducing major disability would improve cost-effectiveness of health-policy decisions more than reducing mortality.

Abstract:
When allocating indivisible resources or tasks, an envy-free allocation or equitable allocation may not exist. We present a sufficient condition and an algorithm to achieve envy-freeness and equitability when monetary transfers are allowed. The approach works for any agent valuation functions (positive or negative) as long as they satisfy superadditivity. For the case of additive utilities, we present a characterization of allocations that can simultaneously be made equitable and envy-free via payments. Our study shows that superadditive valuations constitute the largest class of valuations for which an envy-free and equitable outcome exists for all instances. We then present a distributed algorithm to compute an approximately envy-free outcome for any class of valuations.

Abstract:
Abstract Background The TTO task involves giving up life years, i.e. living a shorter life, to avoid an undesirable health state. Despite being a hypothetical task, some respondents take other life factors into account when completing the task. This study explored the effect of having children and/or a partner on TTO valuations of hypothetical EQ-5D-5L health states in a valuation study of the general population. Methods The study used TTO data collected in a Norwegian EQ-5D-5L valuation study in 2019–2020, by one-to-one pc-assisted interviews following the EQ-VT protocol. We used regression modelling to determine the effect of significant others (having children or a partner) on disutility per health state from the TTO valuations. Results 430 respondents were included [mean age 43.8 (SD 15.9) years, 58% female, 48% with children, 68% with a partner, 25% with neither children nor partner]. Having children and/or a partner was associated with lowered willingness to trade life years translating to higher elicited health state utilities (p < 0.01). Conclusion Having significant others, or the lack of having significant others, was associated with respondents’ valuation of hypothetical health states using TTO, more so than traditional sampling variables such as age and sex. Inadequate representativeness in terms of having significant others could bias health state preference values in valuation studies.

Abstract:
This article assessed how Indian providers and mothers value quality of life in pediatric disabilities, hypothesizing lower values with increasing disability, lower values among providers than mothers, and lower values among mothers with versus mothers without a disabled child. We asked 175 participants: “If born tomorrow, how many years of a disabled life ( y) would you trade to avoid life-long disability” for 4 hypothetical disabilities, calculating “utility” scores as: (life span – y) / life span, where death = 0 and full life without disability = 1. Providers’ utilities were 0.67 (mild), 0.18 (moderate), –0.70 (severe), and –0.60 (profound); 0.67, 0, –0.77, and –0.88 for mothers without and 0.38, –0.49, –0.86, and –0.87 for mothers with a disabled child. Mothers without reported lower utilities than providers (severe and profound disability [ P ≤ .03]), and higher utilities than mothers (for mild and moderate disability [ P < .001]). Major disability is valued as a fate worse than death in India.

Abstract:
Introduction. The EQ-5D-5L valuation protocol contains both time tradeoff (TTO) tasks and discrete choice experiments (DCE), raising the question of how to best use these in creating a value set. The hybrid model, which combines TTO and DCE data, has emerged as a commonly used approach. However, this model assumes independence among responses from the same individual, a linear relationship between TTO and DCE utilities, and, in many implementations, homoscedastic residuals. The aims of this study are to examine alternatives to these assumptions and determine the impact of misspecification on value sets. Methods. We performed a simulation study, parameterized using the US EQ-5D-5L valuation study, to assess the impact of model misspecification. We simulated TTO and DCE data with nonlinear relationships between TTO and DCE utilities, heteroscedastic errors, and correlated responses. Simulated data were analyzed using hybrid models with and without heteroscedasticity, Tobit models with and without heteroscedasticity, a latent class model, and a mixed model. Results. Mean absolute errors (MAEs) for correctly specified models were <0.05, whereas models that incorrectly assumed a linear relationship between TTO and DCE utilities or homoscedasticity of TTO responses featured states with an MAE >0.1. When a linear relationship between TTO and DCE utilities held, using both TTO and DCE data under correct specification yielded smaller MAEs compared with using TTO data alone but yielded larger MAEs when a linear relationship did not hold. Mistakenly assuming homoscedasticity led to increased MAEs, whereas ignoring dependence did not. Conclusions. Because heteroscedasticity in TTO utilities and nonlinear associations between DCE and TTO utilities have been noted, we recommend careful assessment of scedasticity and linearity to ascertain the suitability of a hybrid model.

Abstract:
Summary Mechanisms of valuation of public goods on the agricultural land market - considerations in the context of sustainable development Since the beginning of human civilization, the land has been creating certain utilities which satisfy human needs. When the dangerous side effects of industrial agriculture have occurred intrinsic land utilities are being discovered anew. They have a nature of public goods and constitute a hard core of the sustainable agriculture paradigm. Despite irreversible accumulation of capital in the anthropogenic environment many new utilities of the land come into existence without additional capital and labour outlay. Since they are public goods, they are paid from taxes in great measure. This way an intrinsic land utility takes a form of a financial product and can be called „intrinsic productivity” of land. The aim of the elaboration is to identify the mechanism that make intrinsic land utility transforms into productivity in monetary units. A conducted research consists in deriving a land rent capitalized in land prices and estimating its share in land value in comparison with the share of lease fees in the different regions of Poland in years 2000-2009. In the authors’ opinion since accession of Poland to the UE a market valorizes intrinsic utilities of land, whereas the new role of capital and labour is distribution of those utilities for consumers.

Full text
Abstract:
This study was prompted by the 1988 introduction by the Commonwealth Government, and later on by both Federal and State regulators, of a philosophy of wanting to achieve a target rate of return within the public sector to emulate private sector efficiency. At the core of the reforms was the adoption of replacement values for assets. This resulted in inflated prices to the users of public services and regulated monopoly assets such as energy utilities, while asset owners enjoyed windfall gains. In developing a form of regulation for natural monopolies the regulators initially looked to Accounting. However Finance Economics provided a structure called the Building Block approach to regulation that had at its center the notion of Depreciated Optimised Replacement Cost (DORC). Capture by Finance Economics, has meant that regulation has developed under the rules of Net Present Value based on the DORC value for assets. Net Present Value calculations are based on the timing and amounts of future cash transactions. This is the meat of regulation. The regulators have addressed the problem of circularity by developing a notion of Optimised Replacement Cost (ORC), and calling on the notion of Tobins Q to transform ORC to ORC used, or DORC. Deprival Value has been endorsed as a valuation principle by the Council Of Australian Governments; however Deprival Value conflicts with DORC in the valuation of sunk assets. This research has critically examined the regulators use of DORC and its inherent circularity and finds that DORC is a flawed concept. It is argued that actual or previously agreed values for assets would produce a better regulatory outcome and fairer prices for consumers. The International Financial Reporting Standards contain in their 2003 Framework notions of Fair Value and Capital Maintenance that address the aims of the regulators and are compatible with Deprival Value. Audited financial reports based on the regulators approved asset valuations and prepared in accordance with International Standards would provide cohesion between regulatory decisions and the financial results of natural monopoly companies.

Abstract:
Valuing a company is an important task in finance, especially before a potential merger or acquisition of a company. It is then of great importance for both parties in a deal to make an accurate estimate of the value of the company. The goal of this paper is to investigate how well regression analysis can be applied in this matter and if it can perform at par or better than more frequently used methods in the industry today. The study was conducted within the utilities sector in the US and Europe, with data collected from historic public transactions dating back to 2009. The study concludes that a regression model as a valuation tool can generate several advantages as it identifies key value drivers and is based on core mathematical concepts. However, the model created in this thesis underperforms compared to the prominent methods in place today. For further research this thesis may provide useful insight into different areas to consider when creating a valuation model.
Att värdera ett företag är en viktig uppgift inom finanssektorn, särskilt innan en potentiell sammanslagning eller förvärv av ett företag. Det är då av stor vikt för båda parter i en affär att göra en exakt uppskattning av företagets värde. Målet med denna studie är att undersöka hur väl regressionsanalys kan tillämpas i denna fråga och om den kan generera samma eller bättre resultat än mer använda värderingsmetoder inom branschen idag. Studien genomfördes inom el-, gas- och vattensektorn i USA och Europa, med data som samlats in från historiska offentliga transaktioner som går tillbaka till 2009. Studien drar slutsatsen att en regressionsmodell som ett värderingsverktyg kan generera flera fördelar eftersom den identifierar viktiga faktorer som driver en värdering och baseras på grundläggande matematiska begrepp. Modellen som skapats i denna avhandling underpresterar dock jämfört med de framstående metoderna som finns idag. För ytterligare forskning kan denna studie ge användbar insikt i olika områden att beakta när man skapar en värderingsmodell.

This thesis aims to identify the determining factors of the RAB premium and to define what part is ascribable to factors relating to the fundamentals of the company and what part to factors of a financial nature. Moreover, it attempts to provide an interpretation of the dynamic nature of Snam Rete Gas and Terna share prices according to the options theory and considers the fact that share performance has fluctuated but always remained above the value of invested capital allowed by the regulator, namely the RAB.

This case study adopts Discounted Cash Flow (DCF) and Economic Value Added (EVA) Model to assess the enterprise value of Company C in the industry of the public natural gas utilities. The first step is to identify the business key value drivers via sensitivity and scenario analysis in order to bring out a value strategy for the company. The result concludes that the key value drivers are operating cost and expense , revenue , weighted average cost of capital and invested capital. Finally, strategic and financial aspects would be carried out with value added suggestions via key value drivers for Company C.

The chapter starts to describe a new solution to the problem of choosing for changing selves. It proposes that we should consider it as a judgement aggregation problem. In a judgement aggregation problem, a collective entity is required to aggregate the beliefs and values of the various entities that make it up before making a decision on the basis of those collective attitudes. In the Aggregate Utility Solution, the individual agent is the collective and the selves are the entities that make it up. The chapter asks, in particular: at what level should we aggregate the utilities of the selves to give the utilities of the individual agent? At the level of the preference orderings, or the valuation functions, or the credence and utility functions?

Abstract:
Strategic adaptability is essential in capitalizing on future investment opportunities and responding properly to market trends in an uncertain environment. Customized products or services are an important source of revenue for many companies, particularly those working with in a mass customization environment where customer satisfaction is of paramount important. In this paper, we extend methods from mass customization and product family design to create specific methods for universal product family design. The objective of this research is to propose a valuation financial model to facilitate universal design strategies that will maximize the expected profit under uncertain constrains. Real options analysis is applied to estimate the valuation of options related to introducing new modules as a platform in a universal product family. We use customers’ preferences based on performance utilities for universal design to reflect demand and demographic trends. To demonstrate implementation of the proposed model, we use a case study involving a family of light-duty trucks. We perform sensitivity analysis to investigate the behavior of the estimated option value against chaining system parameters.

Abstract:
Microturbines have showed good perspectives for the distributed generation of the electricity in low capacity range, because they have high reliability and simple design (high potential for a cheap manufacture and in large scale). Besides, this technology must have a great application in systems of cogeneration of the public service (malls, hotel, hospital, etc.) and in the distributed generation of the electricity in the developing countries in order to get a reliable operation system, in a range of power compatible with the isolated communities. In Brazil, The Thermal Systems Study Group (NEST) of Federal University of Itajuba´ (UNIFEI) sponsored by The Energy Company of Minas Gerais (CEMIG), are developing a project of experimental valuation of the system with microturbines for electricity generation fueled with natural gas and diesel. The objective of this paper is to show an economic evaluation which presents the generation costs and the payback period with the Capstone 30 kW natural gas microturbines business in three cases: microturbines operating on base load in gas station, microturbines operating on peak shave in the industry and a microturbine cogeneration system operating in the residential segment. It was considered the cost of microturbines at this moment and the projection for the future, as well as the cost of electricity and natural gas in Brazil. An economical analysis was carried out for different variables involved and the results show the Capstone 30 kW natural gas microturbines business are feasible firstly in cogeneration cases which is possible to get until 3 years of payback period. Besides, the return on the investment have shown improvements with the incentive of the natural gas distributing companies and with the rises in the electricity price of Brazilian utilities.

Abstract:
We study the problem of allocating m indivisible items to n agents with additive utilities. It is desirable for the allocation to be both fair and efficient, which we formalize through the notions of envy-freeness and Pareto-optimality. While envy-free and Pareto-optimal allocations may not exist for arbitrary utility profiles, previous work has shown that such allocations exist with high probability assuming that all agents’ values for all items are independently drawn from a common distribution. In this paper, we consider a generalization of this model where each agent’s utilities are drawn independently from a distribution specific to the agent. We show that envy-free and Pareto-optimal allocations are likely to exist in this asymmetric model when m=Ω(n log n), which is tight up to a log log gap that also remains open in the symmetric subsetting. Furthermore, these guarantees can be achieved by a polynomial-time algorithm.

We study a dynamic social choice problem in which an alternative is chosen at each round according to the reported valuations of a set of agents. In the interests of obtaining a solution that is both efficient and fair, we aim to maximize the long-term Nash social welfare, which is the product of all agents' utilities. We present and analyze two greedy algorithms for this problem, including the classic Proportional Fair (PF) algorithm. We analyze several versions of the algorithms and how they relate, and provide an axiomatization of PF. Finally, we evaluate the algorithms on data gathered from a computer systems application.

Core properties of mechanisms, such as strategy-proofness or budget-balance, involve: (i) complex strategic concepts such as Nash equilibria, (ii) quantitative aspects such as utilities, and often (iii) imperfect information,with agents’ private valuations. We demonstrate that Strategy Logic provides a formal framework fit to model mechanisms, express such properties, and verify them. To do so, we consider a quantitative and epistemic variant of Strategy Logic. We first show how to express the implementation of social choice functions. Second, we show how fundamental mechanism properties can be expressed as logical formulas,and thus evaluated by model checking. Finally, we prove that model checking for this particular variant of Strategy Logic can be done in polynomial space.
