ABSTRACT This research describes the analysis of a Brazilian international airline of a regular passenger air transport company, modeled according to real options analysis. Such analysis is appropriate since the air transport industry, nowadays, in crisis in Brazil and in the USA, is subjected to strong uncertainties such as passenger revenue and airplane fuel prices. Through real options analysis, we show that flexibility due to the options to expand and reduce flight frequencies or even to abandon operations, together with market uncertainties, adds considerable value to an air carrier's planes, making it possible to show its creditors a less myopic business viability when compared to traditional valuation methods. RESUMEN. Esta investigación describe el análisis elaborado sobre una empresa brasileña de transporte aéreo internacional de pasajeros, trazada de acuerdo a un análisis de las alternativas reales. Este tipo de análisis se considera apropiado, ya que la industria de transporte aéreo, que actualmente sufre una crisis tanto en Brasil como en los Estados Unidos, está sujeta a fuertes incertidumbres tales como los ingresos obtenidos con el transporte de pasajeros y los precios del combustible aéreo. Gracias al uso del análisis de las alternativas reales, demostramos que la flexibilidad resultante de las alternativas de expansión y reducción de las frecuencias de los vuelos o hasta el abandono de ciertas operaciones, conjuntamente con otras incertidumbres del mercado, agregan un valor considerable a las aeronaves de la aerolínea, permitiendo que muestre a sus acreedores una factibilidades menos restringida en comparación a la obtenida con los métodos de evaluación tradicionales. RESUMO. Esta pesquisa descreve a análise de uma rota aérea internacional de uma companhia brasileira de transporte aéreo regular de passageiros, modelada a partir da análise de opções reais. Tal análise se mostra apropriada uma vez que o setor de transporte aéreo, atualmente em crise no Brasil e nos EUA, está sujeito a consideráveis incertezas, tais como receita de passageiros e preços do combustível de avião. Através da análise de opções reais, mostramos que a flexibilidade proporcionada pelas opções de expandir ou reduzir freqüências de vôo ou até mesmo abandonar operações, somada às incertezas do mercado, adicionam valor considerável a uma companhia aérea de carreira, possibilitando mostrar a seus credores uma viabilidade de negócio menos míope quando comparada àquelas geradas por métodos tradicionais de avaliação. 相似文献

The NOAA panel for Contingent Valuation opened up the question of the possibility of using trichotomous choice discrete formats in CV studies. In this paper we show how the trichotomous choice format can be used for testing the successfulness of the project definition in the questionnaire. We shall define the vagueness band around the true outcome of the project to be valued and we allow it to be asymmetric. It is shown how this asymmetry can be modelled and estimated. We also show how these new models are generalisations of ordinary ordered probit/logit models. 相似文献

The well-known binomial and trinomial tree models for option pricing are examined from the point of view of numerical efficiency. Common lattices use a large part of time resources for calculations which are almost irrelevant for the solution. To avoid this waste of resources, the tree is reduced to a lean form which yields the same order of convergence, but with a reduction of numerical effort. In numerical tests it is shown that the proposed method leads to a significant improvement in real calculation time without loss of accuracy for a broad class of derivatives. 相似文献

The Ohlson (1995) model assumes that abnormal earnings follow an AR(1) process primarily for reasons of mathematical tractability. However, the empirical literature on the Garman and Ohlson (1980) model finds that the data support an AR(2) lag structure for earnings, book values and dividends. Moreover, the AR(2) process encompasses a far richer variety of time series patterns than does the AR(1) process and includes the AR(1) process as a special case. This paper solves the Ohlson model directly for an AR(2) abnormal earnings dynamic. The model is estimated on a time series firm-level basis following the approach used by Myers (1999). It is found that, like the Ohlson AR(1) model, the Ohlson AR(2) model severely underestimates market prices even relative to book values. These results further bring into question the empirical validity of the Ohlson model. 相似文献

Hedonic price models for determining marginal implicit prices of open-space amenities and nonresidential land use were estimated using housing data from the census. Alternative model specifications were compared to evaluate the effects of aggregating land-use data by alternative levels of census geography as well as the use of different sample sizes of census blocks. It was determined that land use is best aggregated at the block group level and that entire populations or very large sample sizes of census blocks should be used with hedonic models. 相似文献

This paper tests two hypotheses derived from the Data et al. (1991) theoretical model of auditor choice by companies newly listing on the stock exchange. The results offer support to their predictions of the demand for auditor quality. In particular, higher-risk companies are associated with the selection of a high-quality auditor, as proxied by a Big Eight firm of accountants. Additionally, companies who employed Big Eight firms had higher market valuations of their stock at the time of listing. 相似文献
