    Various methodologies exist for valuing companies and their projects. We address the problem of valuing a portfolio of projects within companies that have infrequent, large and volatile cash flows. Examples of this type of company exist in oil exploration and development and we will use this example to illustrate our analysis throughout the thesis. The theoretical interest in this problem lies in modeling the sources of risk in the projects and their different interactions within each project. Initially we look at the advantages of real options analysis and compare this approach with more traditional valuation methods, highlighting strengths and weaknesses ofeach approach in the light ofthe thesis problem. We give the background to the stages in an oil exploration and development project and identify the main common sources of risk, for example commodity prices. We discuss the appropriate representation for oil prices; in short, do oil prices behave more like equities or more like interest rates? The appropriate representation is used to model oil price as a source ofrisk. A real option valuation model based on market uncertainty (in the form of oil price risk) and geological uncertainty (reserve volume uncertainty) is presented and tested for two different oil projects. Finally, a methodology to measure the inter-relationship between oil price and other sources of risk such as interest rates is proposed using copula methods.Imperial Users onl

    Embedded Options and the Case Against Compensation in Contract Law

    Get PDF
    Despite the fact that compensation is the governing principle in contract law remedies, it has tenuous historical, economic and empirical support. A promisor's right to breach and pay damages (which is subject to the compensation principle) is only a subset of a larger family of termination rights that do not purport to compensate the promisee for losses suffered when the promisor walks away from the contemplated exchange. These termination rights can be characterized as embedded options that serve important risk management functions. We show that sellers often sell insurance to their buyers in the form of these embedded options. We explain why compensation is of little relevance to the option price agreed to by the parties, which is a function of the value of the option to the buyer, its cost to the seller and the market in which they transact. We thus propose a novel justification for why penalty liquidated damages may be higher than seller's costs: they are option prices that reflect the value of the options to the buyer. The regulation of liquidated damages is thus tantamount to price regulation, which is outside the realm of contract law. Moreover, in light of the heterogeneity among optimal option prices, we also make the case against having an expectation damages default rule to begin with. In thick markets, we argue for enforcing the parties ex ante risk allocation with market damages. In thin markets, we propose that parties be induced to agree explicitly with respect to all termination rights, including breach damages, by the threat of specific performance of their contemplated exchange or, in the case of consumers, by a default rule that provides them a termination option at no cost.

    Incentive-aligned Conjoint Analysis

    Because most conjoint studies are conducted in hypothetical situations with no consumption consequences for the participants, the extent to which the studies are able to uncover "true" consumer preference structures is questionable. Experimental economics literature, with its emphasis on incentive alignment and hypothetical bias, suggests that more realistic incentivealigned studies will result in stronger out-of-sample predictive performance of actual purchase behaviors and provide better estimates of consumer preference structures than hypothetical studies. To test this hypothesis, the authors design an experiment with conventional (hypothetical) conditions and their parallel incentive-aligned counterparts. Using Chinese dinner specials as the context, the authors conducted a field experiment in a Chinese restaurant during dinnertime. The results provide strong evidence in favor of incentive-aligned choice conjoint analysis, in that incentive-aligned choice conjoint outperforms hypothetical choice conjoint in out-of-sample predictions (59% versus 26% for incentive-aligned choice conjoint and hypothetical choice conjoint, respectively for the top two choices). As expected, subjects in the incentive-aligned choice condition exhibit preference structures that are systematically different from the preference structures of subjects in the hypothetical condition. Most notably, the subjects in the incentive-aligned choice condition are more price sensitive and exhibit different heterogeneity patterns. To determine the robustness of these results, the authors conducted a second study that used snacks as the context and only considered the choice treatments. This study confirmed the results by again providing strong evidence in favor of incentive-aligned choice analysis in out-of-sample predictions (36% versus 16% for incentive-aligned choice conjoint and hypothetical choice conjoint, respectively for the top two choices). The results provide a strong motivation for conjoint practitioners to consider conducting their studies in realistic settings using incentive structures that require participants to æ–—ive with?their decisions.

    Choice Experiments in Enviromental Impact Assessment: The Toro 3 Hydroelectric Project and the Recreo Verde Tourist Center in Costa Rica

    Get PDF
    Choice experiments, a stated preference valuation method, are proposed as a tool to assign monetary values to environmental externalities during the ex-ante stages of environmental impact assessment. This case study looks at the impacts of the Costa Rican Institute of Electricity’s Toro 3 hydroelectric project and its affects on the Recreo Verde tourism center in San Carlos, Costa Rica. Compared to other valuation methods (e.g., travel cost and contingent valuation), choice experiments can create hypothetical but realistic scenarios for consumers and generate restoration alternatives for the affected good. Although they have limitations that must be taken into account in environmental impact assessments, incorporating economic parameters—especially resource constraints and tradeoffs—can substantially enrich the assessment process.stated-preference, economic valuation, choice experiments, hydropower, tourism, Costa Rica

    Suit the action to the word, the word to the action: Hypothetical choices and real decisions in Medicare Part D

    Get PDF
    In recent years, consumer choice has become an important element of public policy. One reason is that consumers differ in their tastes and needs, which they can express most easily through their own choices. Elements that strengthen consumer choice feature prominently in the design of public insurance markets, for instance in the United States in the recent introduction of prescription drug coverage for older individuals via Medicare Part D. For policy makers who design such a market, an important practical question in the design phase of such a new program is how to deduce enrollment and plan selection preferences prior to its introduction. In this paper, we investigate whether hypothetical choice experiments can serve as a tool in this process. We combine data from hypothetical and real plan choices, elicited around the time of the introduction of Medicare Part D. We first analyze how well the hypothetical choice data predict willingness to pay and market shares at the aggregate level. We then analyze predictions at the individual level, in particular how insurance demand varies with observable characteristics. We also explore whether the extent of adverse selection can be predicted using hypothetical choice data alone

    Environmental valuation, ecosystem services and aquatic species

    The thesis consists of an introduction and four articles that can be read independently of each other. The common topic is environmental valuation and cost-benefit analysis. The applications relates to the growing concern of invasive species, and to waterpower externalities. In broad terms, all of the articles relates to water management. Article 1: "A Cost-Benefit analysis of introducing a non-native species: the case of signal crayfish in Sweden", assesses the economic impact of introducing the signal crayfish into a Swedish lake. Two scenarios are set up and compared. The first one assumes that there is no introduction of signal crayfish, so that the noble crayfish is preserved. In the second scenario, the signal crayfish is introduced, which immediately wipes out the entire stock of noble crayfish. The values of noble- and signal crayfish populations are measured as present values of their net future revenues. The values are than compared and net benefit of an introduction is calculated. The result indicate that net benefit of an introduction is positive if the intrinsic growth rate or the carrying capacity of the noble crayfish is below 40 % that of the signal crayfish. Article 2: "Assessing management options for weed control with demanders and non-demanders in a choice experiment", estimates the benefits of having a weed management program for a lake in Sweden, and then compares them with corresponding costs. The policy recommendation from a simple cost-benefit rule is to control the weed at some specific sites of the lake. This paper also suggest how to distinguish those that have a positive WTP for at least one of the attributes (demanders) from those that have zero WTP for all attributes (non-demanders). The advantage of the suggested approach is that it facilitates to more clearly distinguish between conditional and unconditional willingness to pay. The suggested approach could also overcome some of the problems in the literature with negative welfare measures. Article 3: "Assessing transfer errors in the benefit transfer method: An application of invasive weed management using choice experiment", tests the accuracy of transferring benefits of a weed management program from one lake to another using choice experiment. The transfer errors are assessed and the convergent validity hypothesis is tested. Estimating the accuracy of benefit transfer for weed management is policy relevant as there are a number of lakes in Sweden infested with the water weed. The convergent validity was rejected for three out of five welfare estimates with a ten per cent significance level. Article 4: "Willingness to pay for environmental improvements in hydropower regulated rivers", assesses the benefits of environmental improvements along hydropower regulated rivers using choice experiments. Remedial measures that improve the conditions for fish, benthic invertebrates and river-margin vegetation were found to have a significant welfare increasing impact. The results can be of value for the implementation of the Water Framework Directives in Sweden, which aims to reform the use of all surface water and ground water in the member states

    IDENTIFYING CONSUMER VALUATION PATTERNS OF ALTERNATIVE NUTRITION AND HEALTH LABELS COMBINATIONS: EVIDENCE FROM SPAIN

    Get PDF
    The provision of nutrition and health information on food labels is increasing as an industry and regulation answer to the growing consumer concern with diet-health relationships. Prior research has shown that the presence of this information on food labels is valued by consumers; however there is still no clear pattern on which labelling options are more valued and how different consumers value the different options. This paper analyses the results of a choice experiment conducted to identify the effect of multiple health and nutrition information sources on consumer food choice, taking into account preference heterogeneity using a latent class approach. Results show that different consumer groups can be identified with clearly distinguishable valuation and behavioural patterns. A minority of consumers attaches high WTP to the provision of additional information in the nutrition facts panel, however this is not show for a vast majority who value claims. Moreover, not taking into account this preference heterogeneity can lead to policies that do not maximize consumer welfare. Based on the characteristics of consumers identified in each group, recommendations are made as to how both industry and public administration can move forward with the development of nutritional labelling guidelines or policies.Nutrition facts panel, latent class, choice experiments, consumer, interactions, health claims, nutrition claims, Consumer/Household Economics, Food Consumption/Nutrition/Food Safety, Health Economics and Policy,
