This paper presents a version of the proportionally calibrated almost ideal demand system (PCAIDS) model, useful for merger simulations, which can be econometrically estimated using price data for two firms in a market. PCAIDS is therefore seen as a set of restrictions to be imposed in an econometric estimation, and not only as a pure calibration method. The proposed model is applied to a database of the Argentine gasoline market, and its results are compared to the ones obtained with other alternative specifications.

The aim of this paper is to compare the performance of a theoretically optimal portfolio with that of a moving average-based strategy in the presence of parameter misspecification. The setting we consider is that of a stochastic asset price model where the trend follows an unobservable Ornstein–Uhlenbeck process. For both strategies, we provide the asymptotic expectation of the logarithmic return as a function of the model parameters. Then, numerical examples are given, showing that an investment strategy using a moving average crossover rule is more robust than the optimal strategy under parameter misspecification.  相似文献

This paper investigates the relationship between divestitures and firm value in family firms. Using hand‐collected data on a sample of over 30,000 firm‐year observations, we find that family firms are less likely than non‐family firms to undertake divestitures, especially when these companies are managed by family rather than non‐family‐CEOs. However, we then establish that the divestitures undertaken by family firms, predominantly those run by family‐CEOs, are associated with higher post‐divestiture performance than their non‐family counterparts. These findings indicate that family firms may fail to fully exploit available economic opportunities, potentially because they pursue multiple objectives beyond the maximization of shareholder value. These results also elucidate how the characteristics of corporate owners and managers can influence the value that firms derive from their corporate strategies.

Members' shares in co‐operative entities are financial instruments with particular characteristics. In this paper we analyse the relation between firm leverage and systematic risk to provide empirical evidence on the economic substance of the member shares of members of cooperatives. We have studied the characteristics of members' shares in six European countries: France, Germany, Italy, Portugal, Spain and United Kingdom. We have also conducted tests on co‐operatives of these countries over the period 1993–2005. The study reports that in global terms the economic substance of the redeemable part of equity in co‐operatives is not the same across countries. Therefore if accounting standards setters want to develop a global standard for co‐operatives, a recommendation derived from this study would be to follow a probabilistic model to classify the redeemable part of co‐operative financial instruments, where the entity does not have the unconditional right to refuse the redemption, or to report this part as an intermediate item with characteristics of debt and equity.  相似文献

Structural equation models with mean structure and non-linear constraints are the most frequent choice for estimating interaction effects when measurement errors are present. This article proposes eliminating the mean structure and all the constraints but one, which leads to a more easily handled model that is more robust to non-normality and more general as it can accommodate endogenous interactions and thus indirect effects. Our approach is compared to other approaches found in the literature with a Monte Carlo simulation and is found to be equally efficient under normality and less biased under non-normality. An empirical illustration is included.  相似文献

The recent crisis caused by COVID-19 directly affected consumption habits and the stability sof financial markets. In particular, the football industry has been hit hard by this pandemic and therefore has more volatile stock prices. Given this new scenario, further research is needed to accurately estimate the value of the shares of football clubs. In this paper, we estimate an asset pricing model in football clubs with different compositions of risk nature using non-linear techniques of artificial neural networks. Usually, asset pricing models have been estimated with linear methods such as ordinary least squares. Our results show a precision higher than 90% for all the estimated models, which far exceeds those shown by linear methods in the previous literature. We find that the residual represents about 40% of the variance of the price-dividend ratio. Long-term risks follow in importance, and above all, the habit component and its behaviour in the face of changes. The importance of the residual component exists due to a low correlation between the asset price and consumer behaviour, but to a much lesser extent than that shown in previous studies. The estimation carried out with artificial neural networks, both the Deep Learning methods and especially the Quantum Neural Network, opens up new possibilities to estimate more efficiently the pricing of financial assets in the football industry.  相似文献

This paper sets out to analyse the information dedicated to climate change and tourism in the Spanish press in the Mediterranean region of the peninsula during the period 1990–2010. Specifically, it seeks to determine the quantitative evolution of media coverage of climate change and tourism and the importance given to this subject. Adequate media attention in both quantitative and qualitative terms could greatly influence public concern and contribute to the social mobilization that will be needed to negotiate/resist the phenomenon in a geographical area in which tourism is a major economic and territorial driver and which is particularly vulnerable to climate change. To construct the corpus, we undertook a systematic analysis of newspaper coverage of tourism and climate change in the media selected; and we carried out content analysis of the 1014 units identified. The results indicate that the coverage is outstanding in quantitative terms. However, the importance given to the subject is quite marginal.  相似文献

This paper studies first-mover advantage in the mobile telecommunications services industry. There are very few empirical studies of pioneer advantage in service industries, possibly because of the difficulty of building competitive advantages in an industry where innovations cannot be protected and competitive actions can be easily imitated. The empirical research was carried out using data from a sample of European mobile telecommunications firms from 1993 to 2005. The findings indicate that an order of entry advantage does exist, but that this advantage diminishes with time in competition. Regarding the impact of the main sources of pioneering advantages, the results show that it is harder for follower firms to erode first-mover advantages when the pioneer has prior experience in the industry and when there are two pioneers instead of one. Lastly, number portability between different operators was found to damage the competitive position of the pioneer firms.  相似文献

Scholars and local planners are becoming increasingly interested in the contribution of tourism to economic and social development. In the European cities that currently lead the world rankings for tourist arrivals, local governments have actively promoted tourism. Mobility is an essential issue for tourists visiting large cities, since it is a crucial factor for their comfort. It also facilitates the spread of benefits across the city. This study uses an international database of European cities to examine whether city planners respond to the additional demand for urban public transport by extending service supply. Our results confirm that tourism intensity is a demand-enhancing factor in urban public transport. However, cities do not seem to address this pressure by increasing services. Tourism appears to exert a positive externality on public transport, since it provides additional funding for these services, but it also imposes external costs on resident users because of the congestion caused by supply constraints.  相似文献

As e-commerce growth continues to surpass that of brick-and-mortar retail, temporary retail spaces, also known as pop-up shops, are becoming an important promotional strategy, especially for online retailers and service providers. Success in today’s retail environment means being able to create and maintain brand communities, to generate instant and measurable hype, and to deliver personalized consumer experiences—all of which can be readily achieved through a strategically placed physical business presence. In this study, a survey of retailing organizations worldwide reveals that among those that had implemented at least one pop-up shop, more than 80% considered it a success. The results also show that the primary reasons for activating pop-up shops were to create connections with current and potential customers, to increase brand awareness, to introduce a new product or brand to the marketplace, and to stage a new product or brand. While the respondents deemed revenue generated at pop-up shops important, they considered improving market visibility (e.g., through social media, website traffic, or media coverage) a more significant objective. Given the economic potential of pop-up shops, this research provides retailing organizations with guiding principles for developing and operating successful pop-up shops in the current marketplace.  相似文献
