This paper concerns the behavior of gold and silver prices on a daily, weekly and monthly time span during January 1970 to December 1989. The methodology consists of extracting the predictive power of time series of changes in past prices for obtaining optimal forecasts for next-period changes in prices. Optimizations are made in the context of information theory via minimizing the degree of diversity between the actual and predicted changes in prices. This methodology has merit in that it does not rest on, generally speaking, unacceptable assumptions regarding the shape of the distribution, stationarity of variance or its existence. The behavior of gold and silver prices are studied during peak to trough and trough to peak of the business cycles over 1970–1989. It is generally shown that information contained in past prices of gold and silver does not allow one to predict next-period changes in prices in the short run. However, longer-term predictions are possible. This study further reveals that as the length of the time interval expands, gold prices exhibit a higher degree of dependency on past prices than silver. 相似文献

Multinationals from emerging economies are relatively new players in the global economy. This Special Issue includes five articles that cover several important aspects of the market and nonmarket strategies pursued by emerging market multinational corporations (EMNCs). Given that only a few firms from emerging markets embrace the possibilities and challenges of going global, we highlight the need to examine country, industry, and firm level antecedents of the emergence of EMNCs. We also draw attention to the need to study the role played by immigrant populations in EMNC internationalization. 相似文献

Marketing's role in supporting a company's efforts to develop pioneering and incremental products can be quite different. Abdul Ali examines published articles and offers a set of propositions to show how several factors influence the product development decision. He cites examples from the business world to illustrate these propositions. This article suggests that a firm should take into account several factors relating to its capabilities, along with various project and market characteristics, in order to decide what products it should develop. 相似文献

As cities look at various industries to strengthen their economies, officials have begun to examine conventions and gaming more closely as they have often been considered “recession-proof.” This study utilizes time series regression to analyze the effects of convention attendance and hotel occupancy on monthly gaming revenues for Las Vegas from 2002 to 2013. Three commonly held opposing viewpoints in trade literature are that conventions reduce, augment, or complement gaming. These viewpoints produced the hypotheses for this study. It was found that convention attendance had no significant relationship with gaming revenue; however, citywide hotel occupancy was found to have a significant positive relationship with gaming revenue. This finding rules out the reduction and augmentation hypotheses. 相似文献

The growth in shadow banking system over the past few years is acknowledged as the key risk to Malaysia's financial stability. This is because that it is associated with growth in the household debts extended by the shadow banks. In line with initiatives by the Bank Negara Malaysia (the Central Bank of Malaysia) to enhance surveillance on the activities of the shadow banks in Malaysia, this study attempts to examine the determinants of default risks of shadow banks restricting to focus on their two main activities: securitization and collateralization. The results provide empirical evidence that future methodology to examine the systemic risks in the shadow banking system may need to account for additional explanatory variables that measure collateralized assets that are being intermediated. 相似文献

The implementation of the education criteria for performance excellence (ECPE)—the education version of the Baldrige criteria—is driven by the growing need for performance excellence in higher education. Ironically the criteria meant for performance excellence have no theoretical underpinning and are based on normative performance improvement requirements. The lack of content and internal validity is reflected in some critical weaknesses in the criteria. Based on a critical review, this paper highlights potential improvements in the areas of aligning processes with the organisational mission, operations focus, customer focus, workforce focus, and performance measurement. To help enhance the ECPE, the paper develops performance measures for systematic implementation of the criteria. This is discussed in terms of defining desired outcomes, developing key measures, identifying specific indicators to track performance, and choosing methods to assess performance. The discussions provide a basis for future revisions to the ECPE. 相似文献
