In this paper, a structural analysis of hybrid censoring models is presented. This new modularization approach to hybrid censoring models enables a convenient derivation of distributional results. For instance, it allows to derive the exact distribution of the MLEs under an exponential assumption for very complex hybrid scenarios. In order to illustrate the benefit of this idea, we apply it to four new unified progressive hybrid censoring schemes. They are extensions of already proposed unified Type-I/II/III/IV hybrid censoring schemes to progressively Type-II censored data. The resulting analysis shows that the modularization approach provides a powerful, efficient, and elegant tool to study even more complex hybrid censoring models. 相似文献

This article aims to identify the determinants that influence business tourism income and that may be controlled by economic agents and policy makers of destination countries. For the development of the empirical study, a dynamic panel model by the Generalized Method of Moments (GMM) was estimated using the Gretl 2016a software, and a sample of 122 countries for the period 2002–2013 (12 years) was used. The study reveals that, for the development of policies to stimulate the growth in the short and long-term of business tourism income, countries should develop measures that encourage capital investment in tourism and foreign direct investment. 相似文献

This article aims to evaluate the service quality experienced at academic conferences held at the Universidad Técnica Particular de Loja in Ecuador. Our approach is based on fuzzy logic and ideal solutions to calculate a global attendee satisfaction index for specific market segments: Gender, nationality, and age. Current literature on the service quality experienced by conference attendees is still scarce. Our results show that the analyzed segments experience varying levels of satisfaction, and that the more influential attributes to each of them are also different. Our results can be applied to improve the competitiveness of Loja and that of Universidad Técnica Particular de Loja. 相似文献

Price transmission,asymmetric adjustment and threshold effects in the cotton supply chain: a case study for Vidarbha,India 下载免费PDF全文
This study examines price transmission asymmetries in Vidarbha's (India) cotton supply chain from 2002 to 2012. The analysis takes account of thresholds in price adjustments toward their long‐run equilibrium. The first stage considers the price dynamics between international and Indian domestic cotton prices. The second stage considers price transmission from domestic to farm gate cotton prices in Vidarbha. Results from the first stage indicate that Indian and international cotton markets are well‐integrated. In contrast, the second stage reveals significant threshold‐type nonlinearities as well as asymmetries in price transmission between domestic and farm gate prices. The short‐run dynamics suggest that the pass‐through from domestic to farm gate prices is larger when domestic prices decrease than when they increase. Moreover, back of the envelope calculations suggest that the loss in revenue for a typical farmer from a decrease in domestic price is larger than the gains from an increase in domestic price of the same magnitude. The implication is that traders benefit from price fluctuations at the expense of farmers. Evidence from fieldwork in Vidarbha suggest that asymmetries revealed in this analysis may be linked to trader's market power and inadequate market information among farmers. 相似文献

The aim of this paper is to analyse the relationship between environmental and economic performance from the resource-based
theory within firms of the fresh fruit and vegetables sector. This study considers that the adoption of environment-friendly
practices has a greater influence on firms’ opportunities and abilities in the agricultural sector than in manufacturing sectors
and leads to closer links between performance variables. The reference for this empirical analysis is a panel data of horticultural
farming-marketing firms in Spain. The voluntary environmental programmes and the heterogeneity of their application lead us
to regard acquiring a competitive advantage as a relevant driver to improve environmental performance in this sector. A simultaneous
equations model is suggested reflecting the differential environmental effect and the assumption of endogeneity among variables.
The results show a positive impact of environmental differentiation on profitability and market share, also suggesting that
the perception of this positive experience implies greater environmental performance.

We document the patterns of market-wide and firm-specific volatility in the Portuguese stock market over the 1991–2005 period
and test several explanations for the behavior of firm-level idiosyncratic volatility. Unlike previous studies we find no
evidence of a statistically significant rise in firm-specific volatility. On the contrary, the ratio of firm-specific risk
to total risk slightly decreases. We show that this result stems from new listings of large privatized companies that display
lower firm-specific risk. Our findings are consistent with the idea that changes in idiosyncratic volatility are related to
changes in the composition of the market.

We introduce asymmetric information about consumers’ transportation costs (i.e., the degree of product differentiation) in the model of Hotelling. When transportation costs are high, both firms have lower profits with asymmetric information than with perfect information. Contrarily, if transportation costs are low, both firms may prefer the asymmetric information scenario (the informed firm always prefers the informational advantage, while the uninformed firm may or may not prefer to remain uninformed). Information exchange is ex‐ante advantageous for both firms, but ex‐post damaging if transportation costs turn out to be low. If the information is unverifiable, the informed firm does not represent a reliable source of information, since it always prefers to announce that transportation costs are high and there is no contract that induces truthful revelation. 相似文献

As a result of policies to reduce public deficit, nonprofit organizations have been forced to turn to charitable donations in order to diversify their revenue structure and thus reduce their levels of financial distress. Public administrations have supported this process through tax mechanisms designed to provide a legal framework that will encourage private philanthropy. Our aim is to analyse the role of nonprofit tax regulations in moderating the influence of revenue diversification on insolvency risk. To this end, we drew a sample of 406 nonprofit organizations located in Aragon and Navarre, two European regions with different tax regulations, for the period 2008–2018. Our results reveal that some tax regime requirements, such as the organizational purpose, minimum initial endowment, engagement in commercial activity, and accountability and monitoring standards, have a positive impact on revenue diversification and the reduction of financial distress and vulnerability. However, we also detect differences between regions which suggest that tax harmonization for nonprofit organizations remains a challenge. 相似文献

The above analysis allows several conclusions to be drawn:

1) | Firstly, deregulation and liberalisation in an economy undergoing the transition from plan to market must differ somewhat from their counterparts in a highly developed market economy. This is because what is being aimed at in the transition process is to modify, not to eliminate the regulatory function of the public administration responsible for planning and implementing new institutional solutions. |
2) | Secondly, privatisation of the public sector must not become a fetish, nor must it be treated as a panacea for rapid systemic changes. For objective reasons, privatisation is not susceptible to shock methods (of the cold turkey type) and therefore it is unable to rapidly induce structural changes. |
3) | Thirdly, the stabilisation policy should be accompanied by a selective industrial policy carried out by the State. And the stabilisation policy must give balanced consideration to the relationship: inflation rate -output level- unempolyment rate. |
