Recent Studies in the area of foreign exchange market efficiency have employed time series analysis to test for the absence of long-run equilibrium or cointegration relationships among the exchange rates for the major currencies. Cointegration directly violates the weak form of the Efficient Market Hypothesis in a speculative efficient market (Granger, 1986). In this study, we address the efficiency of the Tokyo spot foreign exchange market while updating the test procedures developed by Phillips and Ouliaris (1990), Johansen and Juselius (1990) and Johansen (1991). Cointegration is found to be absent, showing that the Tokyo spot market is consistent with the efficient market hypothesis.  相似文献

The importance of accurate credit information on potential clients and customers is even more critical when doing business overseas—a thorough check before committing resources is always a good idea.  相似文献

A study of 198 household units in the Fort Collins, CO area was made to ascertain the importance of such factors as consumer age, income, education and marital status on the purchasing patterns for ground beef. Compared to younger consumers, older consumers tended to: (1) make more frequent purchases of ground beef; (2) buy less ground beef per purchase; and (3) select leaner ground beef. Households with gross incomes in excess of $25,000 tended to buy larger quantities of ground beef per purchase and bought leaner ground beef compared to households with less than $15,000 gross income. In making purchasing decisions, participants in the study considered leanness, visual appearance and price as the most important factors, while packaging and brand name were considered the least important factors.  相似文献

This paper investigates the alleged adverse effect of floating exchange rates on international trade. A simple model is constructed to test the relationship between exchange rate variability and bilateral trade flows between the United States and three of its major trading partners: Canada, Japan and Germany. Using data from 1960 to 1983 to encompass both “stable” and floating rate regimes, it is shown that while exchange rate variability is considerably higher in the floating period, there is no evidence that this greater variability has had a negative impact on trade flows.  相似文献

ABSTRACT

This paper details a study of brand-related bullying in a school setting, among children approximately 11–18 years of age during their schooling experience. Defined as ‘repeated oppression, psychological or physical, of a less powerful person by a more powerful one’, authors have found self-reported rates of bullying above 25%. Our goal was to assess the role of brands and branded products in violent peer socialisation through bullying. Depth interviews lasting between 45 and 90 minutes that captured the retrospective reflection of forty-one 18–20-year-old college students were conducted and data were analysed hermeneutically with iterative comparison to discover emerging themes. Our findings suggest branded products were used to maintain existing social hierarchical structures and exclude non-conforming students through both covert and overt violence. We describe the influence strategies used and address strategies for dealing with the ‘unusual’, including the adoption of an alternative aesthetic for clothing selection.  相似文献

This paper investigates empirically the impact of inflation on the terms of trade, prices received and paid, for Greek farmers in the period 1967–87. According to conventional theory, inflation can have a non-neutral effect if it is unanticipated and if prices received and paid by farmers exhibit different degrees of flexibility. However, in the case where prices are administered, inflation neutrality depends on government's policy objectives and ability to adjust prices of inputs and outputs to the rate of inflation. The empirical investigation undertaken in this study shows that pricing policies implemented by the Greek government have resulted in neutralising the impact of inflation on the terms of trade for Greek farmers. Furthermore, the observed significant variability of the terms of trade can be attributed solely to real demand and supply factors.  相似文献

Mackay Whitsunday Safe Communities (MWSC) was developed using a capacity building model that consciously attempted to design sustainability into the network. Our aim was to quantify the flow of resources used by MWSC to implement and sustain its injury control activities. Resource exchange among network members was quantified and analysed using social network analysis. In 2004, MWSC accessed an estimated 6.5 full-time staff equivalents and $0.9 million. However, these resources were largely accessed externally. The linking relationships that connected MWSC to its external support network, more than half of which were maintained by six broker network facilitators, were the critical social asset used to access resources and sustain network productivity. The sustainability of this network and arguably similar safety promotion networks is vulnerable to the changing priorities of external sponsoring agents and highly dependent on its leaders who facilitated access to the resources it required to remain productive.  相似文献

Knowledge complementarity and innovation   总被引:4,自引:0,他引:4  
This paper uses an innovation production function to relate the presence of geographically-mediated complementary knowledge resources to the innovative activity of small and large firms. The empirical results suggest that small firm innovation appears to benefit from the presence of external institutions and resources. Although large firm innovative activity benefits from the presence of knowledge resources, location appears to be especially beneficial to small firm innovative activity.  相似文献
