We propose and study simple but flexible methods for density selection of skewed versions of the two most popular density classes in finance, the exponential power distribution and the t distribution. For the first type of method, which simply consists of selecting a density by means of an information criterion, the Schwarz criterion stands out since it performs well across density categories, and in particular when the DGP is normal. For the second type of method, general-to-specific density selection, the simulations suggest that it can improve the recovery rate in predictable ways by changing the significance level. This is useful because it enables us to increase (reduce) the recovery rate of non-normal densities by increasing (reducing) the significance level, if one wishes to do so. The third type of method is a generalisation of the second type, such that it can be applied across an arbitrary number of density classes, nested or non-nested. Finally, the methods are illustrated in an empirical application.  相似文献

Industrial manufacturers are innovating their business models by shifting from selling products to selling outcome-based services, where the provider (manufacturer) guarantees to deliver the performance outcomes of the products and services. This form of business model innovation requires a profound yet little understood shift in how value is created, delivered, and captured. To address this research gap, our study examines two successful and four unsuccessful cases of this shift. We find that effectiveness in business model innovation hinges on the three process phases that unfold in collaboration with the customers: value proposition definition, value provision design, and value-in-use delivery. We also find that that success is determined by the alignment of specific value creation and value capture activities in each phase: identifying value creation opportunities—agreeing on value distribution in value proposition definition, designing the value offering—deciding on the profit formula in the value provision design, and finally refining value creation processes—regulating incentive structures in the value-in-use delivery. Our process model contributes to the literature and practice on business model innovation by providing a thorough understanding of how alignment of value creation and value capture processes is ensured, whilst paying special attention to their interdependence and the interactions between provider and customer.  相似文献

Price endogeneity has been ignored in previous analyses of food demand in urban China. We exploit data provided by the China National Bureau of Statistics on agricultural commodity supply shifters and use reduced‐form price equations to account for price endogeneity. Applying our unique econometric approach to the analysis of provincial‐level food demand in China, we find strong statistical evidence of price endogeneity. Models that ignore price endogeneity result in substantially biased elasticities and misleading estimates of future food demand in China.  相似文献

ABSTRACT

Websites have become a fundamental marketing tool for tourism businesses and have a special importance for highly rated restaurants. The aim of this article is to propose and apply a model to evaluate the deployment and adoption of website marketing features of restaurants from a specific category. The model is based on the application of an extended model of Internet commerce adoption (eMICA) technique for technical depth, combined with content analysis for breadth. This study analyzes the website features and capabilities for Spanish restaurants in the 2015 Michelin Red Guide. A total of 102 restaurants were analyzed. The results of the website evaluation model suggest that, despite the importance of the restaurant sector in the economy and in the tourism industry, the websites of high-quality restaurants require improvements to adapt to customers’ demands. Results further found that these websites are not tourist-orientated and are established at different stages of development.  相似文献

There is general agreement that attitudes towards the entrepreneur, entrepreneurial activity, and its social function are determinant factors for university students to decide an entrepreneurial career.This empirical study aims at assessing and comparing the attitudes of university students towards entrepreneurship and enterprise formation in Catalonia and Puerto Rico, using a sample of 837 and 435 students, respectively.Results reveal a positive entrepreneur’s image. Both samples have a favorable perception of desirability of new venture creation, although the perception of feasibility is by far not so positive and only a small percentage has the firm intention to create a new company.  相似文献

On the basis of historical data aggregated over the period 1973 to 2000, we have experimented with four different approaches to estimate the synthetic euro's equilibrium exchange rate. Using a number of competing models with the same data set, variable definitions and sample period offers the possibility to assess the uncertainty surrounding such equilibrium levels, both from an empirical (different estimates) and a theoretical viewpoint (different specifications). In this exercise, the 'Rest of the World' is proxied by the US, the UK, Japan and Switzerland, aggregated on the basis of trade weights.
We employed reduced form co–integration models, a structural VAR, a NATREX model (estimated in structural form) and the ECB's small–sized euro area wide macro–econometric model. In this order the approaches feature an increasing degree of 'structure', in the sense of the constraints based on economic theory embedded in the econometric models that were estimated. The results confirm the high likelihood for the euro having been undervalued in Q4 2000, while stressing the significant empirical and theoretical uncertainty with respect to the equilibrium exchange rate level.  相似文献

This article explores the assumptions underlying present definitions of national income in its principal uses, and considers the alterations that would be needed to allow for the inclusion of environmental quality. A numerical example illustrates the impact of alternative measures. The discussion concludes that if we want national income to conform more closely to theoretical concepts of welfare indices, then we need to include a proxy for those environmental services that would not be completely free goods if it were possible to overcome their inherent non-marketability. The least unsatisfactory proxy would be the spending on environmental protection.  相似文献

This study aimed to analyse the impact that the financial features and characteristics of the ownership structures of international companies exert on the performance of their internationalization process, as perceived by managers, and attempted to detect differences between family firms (FF) and nonfamily firms (non-FF). In addition, the impact of these characteristics and others related to FF, such as family ownership and generation, on the perceived performance of their internationalization is analysed. Based on a sample of Spanish companies with direct investment in China, the results indicated that, from the managers’ perspective, being an FF and having lower financial leverage exerted a positive effect on the performance of the internationalization process. Moreover, the study proved that this performance was strongly and positively related to the financial results of the company, and this positive effect was even stronger in the case of FF. Finally, the findings also showed that FF with a higher involvement of the family in their ownership recognized a better performance of their internationalization process. These results will be useful for companies that are considering the value of internationalization as a strategy to improve or maintain their financial results, and they also highlight certain differences between FF and non-FF.  相似文献
