We approximate probabilistic forecasts for interval-valued time series by offering alternative approaches. After fitting a possibly non-Gaussian bivariate vector autoregression (VAR) model to the center/log-range system, we transform prediction regions (analytical and bootstrap) for this system into regions for center/range and upper/lower bounds systems. Monte Carlo simulations show that bootstrap methods are preferred according to several new metrics. For daily S&P 500 low/high returns, we build joint conditional prediction regions of the return level and volatility. We illustrate the usefulness of obtaining bootstrap forecasts regions for low/high returns by developing a trading strategy and showing its profitability when compared to using point forecasts. 相似文献

More than two decades of economic reforms have brought profound changes in human resource management practices in both the state and non-state sectors in China. This study focuses on the impact of organizational factors on compensation and benefits for Chinese managers in state-owned enterprises (SOEs), publicly listed firms (PLFs), and foreign-invested enterprises (FIEs). The empirical investigation of 465 firms located in three major Chinese cities, Shanghai, Nanjing and Guangzhou, provides evidence that organizational factors, such as ownership, firm size, firm age, location and industrial sector, have significant impacts on the variances in Chinese managers' compensation levels, compensation structures and benefits. The trends in the development of compensation and benefits for Chinese managers are also discussed as the Chinese economy moves closer to a more globalized, highly dynamic economy after China's accession to the World Trade Organization in 2001. 相似文献

Emergent research has examined the antecedents to using information technology (IT) in the new product development (NPD) process and the impact of IT on NPD performance. Based on the resource‐based view (RBV) of the firm, this study hypothesizes that particular resources create IT capabilities that significantly enhance NPD outcomes. More specifically, this research extends previous work by investigating whether three complementary resources, namely an executive champion for IT, global engagement, and organizational innovativeness, influence IT capabilities (IT use frequency and IT replacement frequency), which in turn affect NPD outcomes (NPD task proficiency and NPD performance). To test the conceptual model, survey data were collected from 220 NPD and IT managers in a variety of large Japanese firms. The results show that an executive champion for IT and global engagement are predictors of both IT tool use and replacement frequency while organizational innovativeness contributes only to IT tool replacement frequency. The results also indicate that both IT tool use and replacement frequency have a positive effect on NPD task proficiency, which improves NPD performance. This research contributes to the literature by adding understanding of the role of IT in NPD at the firm level in four ways. First, it examines particular organizational complementary resources and their relationship to IT capabilities. Second, it examines the RBV and IT in the context of NPD, an important business process. Third, it measures IT usage in a more granular fashion (i.e., IT tool use frequency and IT replacement frequency) rather than simply IT usage as a dichotomy. Finally, through testing the proposed model with data collected from Japanese firms, this study provides empirical evidence from an Asian country to answer the call for more NPD research to be conducted in countries other than North American and Western European contexts. The findings of the study also provide implications for managers. Importantly, they indicate that an executive level champion for IT is a key influencer in facilitating IT usage and replacement, and likely can help generate awareness of and support for greater IT investments so the firm can create IT capabilities for effective NPD. 相似文献

The European tomato market is characterized by a constant process of dynamic adjustment towards equilibrium. Furthermore, Canary Island tomato exports cause a high seasonal impact on market prices in the winter period. In these circumstances, an adequate distribution of weekly shipments throughout the year could contribute to maximize producers' profits. Moreover, Canary export levels show some degree of instability, clearly related to the changes in the EU trade rules and there is a long period, in the summer, without exports. The aim of this article is to analyze the long‐term movements and, particularly, the seasonal pattern of Canary Island tomato exports throughout the last two decades. To observe more clearly the exporter's decisions, weekly data have been used. The instabilities in the long‐term behavior of the series and the specific nature of the seasonal pattern should be taken into account, to capture the performance of exports accurately. Thus, this analysis is carried out using the structural approach to time series analysis, and the usefulness of spline functions as a tool capable of modeling seasonal variations for which the period does not remain the same over time is shown. 相似文献

This article reports the results of a study whose purpose was to investigate factors that contribute to the faster development of new products. Edward McDonough and Gloria Barczak collected data from 30 new product development projects in 12 British companies. They investigated the impact of leadership style and the source of the technologies employed in the project (i.e., internally developed or externally acquired) on speed of development. Their results suggest that leadership style influences speed of development. Moreover, the source of the technologies used in the project moderates the relationship between leadership style and speed of development. 相似文献

This study develops an integrative international human resource IHRM framework in Chinese MNEs mainly by examining the relationship between the intervening factors and IHRM policies and practices. It confirms that IHRM is associated with a variety of contextual and firm-specific factors, including political, legal, economic, socio-cultural factors, international strategy, organizational structure, organizational culture, stage and mode of internationalization, type and niche of industry, international experience, size of international operation, the reliance on international markets and top management perceptions of home HRM systems. These factors have differentiated impact and are changing over time. It also explores the impact of IHRM policy and practice on each other, arguing that there is interplay between IHRM policies and practices. 相似文献

This study investigates whether women's empowerment, measured by education attainment relative to her partner, decision‐making, and domestic violence is related to nutritional status of children in Ghana. Using the 2014 Ghana Demographic and Health Survey, the study examines the effect of women empowerment on child's nutritional status at different points in its conditional distributions using ordinary least squares and quantile regression estimation technique. The study observes that women's empowerment is associated with improvement in the nutritional status of children with Z‐scores less than ?4 and ?3 standard deviations, for acutely and severely malnourished children respectively in the long run. The study recommends that the Ministry for Gender and Social Protection should educate male partners on the need for women participation in decision‐making at the household level as well as make formal education accessible to women. 相似文献

This study explores the relative influence of geographical and cognitive proximity to explain innovation performance. This paper deepens the controversy between the significance of both types of proximity, contributing to a better understand their interconnections. The study further analyzes to what extent knowledge acquisition provides a congruent explanation of the effectiveness of innovation in proximity contexts. The paper has tested a structural model based on a sample of 224 Spanish footwear firms. Footwear industry is a mature and traditional industry with a significant presence of the territorial agglomeration of firms all over Spain. Findings suggest both a direct and indirect effect of cognitive proximity on innovation performance. However, an excess of geographical proximity produces spatial lock-in, thus limiting the access to new knowledge and lowering innovations. By contrast, proximity in terms of goals and culture leads firms belonging to a territorial cluster to achieve knowledge acquisition resulting in relevant innovation. Findings suggest that although transferable valuable knowledge exists in clustered contexts firms should adopt a proactive behavior to have access common knowledge and in order to generate effective innovations. 相似文献

Improving the sustainability of farms often incurs additional costs for farmers. These costs come from allocating land to the maintenance of the ecological processes (energy and material flows, natural population regulation) required for the agroecosystem to function. Since these costs are not recovered on the markets, farmers see a fall in profits, the financial viability of their farms is compromised, and they suffer the consequences of the environmental services they are providing. All this makes it essential to implement government policies designed to compensate farmers for their efforts. The issue of how to assess sustainability has generated widespread debate within ecological economics, specifically as to whether it is possible to place a monetary value on it and if so, how this should be done. In a previous article we showed that agrarian sustainability involves a land cost, therefore this cost can be translated into monetary values. The purpose of this study is to develop this concept in practical terms by applying it to organic farming. We calculated the land cost of agrarian sustainability (LACAS) in order to compare organic versus conventional management in olive farming, as this crop is grown extensively in Spain and other Mediterranean countries. The results show that the agro-environmental subsidy is not enough to encourage olive growers to make the conversion from conventional to organic methods, because the land cost of sustainability is not adequately offset. They also show that improving agroecosystems can allow the land to take on more functions without increasing the land cost. In our case, encouraging the multifunctionality of the land has permitted a reduction in this cost. The LACAS could be a useful tool, not only for drawing up government policies designed to support organic farming, but also for improving the sustainability of the agrarian sector. 相似文献
