A Closer Look at the Relation between GARCH and Stochastic Autoregressive Volatility

We show that, for three common SARV models, fitting a minimummean square linear filter is equivalent to fitting a GARCH model.This suggests that GARCH models may be useful for filtering,forecasting, and parameter estimation in stochastic volatilitysettings. To investigate, we use simulations to evaluate howthe three SARV models and their associated GARCH filters performunder controlled conditions and then we use daily currency andequity index returns to evaluate how the models perform in arisk management application. Although the GARCH models produceless precise forecasts than the SARV models in the simulations,it is not clear that the performance differences are large enoughto be economically meaningful. Consistent with this view, wefind that the GARCH and SARV models perform comparably in testsof conditional value-at-risk estimates using the actual data.     

The CNO/CFO partnership: navigating the changing landscape

With increasing pressure to cut costs, both real and immediate, and those forecasted and anticipated, the partnership and collaboration between nursing and finance will continue to take on new challenges. This partnership has historically been strained and does not always come easy due to differences in focus, different priorities, and inadequate communication, listening, and hearing. That needs to change and a strong CNO-CFO partnership is needed. Nursing leaders need to understand and appreciate the financial constraints and balance them with expected outcomes, and financial leaders need to understand and appreciate the core clinical business and what gaps in care mean to the financial viability of the organization and to patient outcomes. One health system developed a platform for change and is dedicated to the hard work involved in continuously working on those partnerships so when it comes to patient quality, safety, and financial performance, nursing and finance leaders are well positioned for future health care challenges.     

Impacts of climate change on lower Murray irrigation*

This article evaluates irrigated agriculture sector response and resultant economic impacts of climate change for a part of the Murray Darling Basin in Australia. A water balance model is used to predict reduced basin inflows for mild, moderate and severe climate change scenarios involving 1, 2 and 4°C warming, and predict 13, 38 and 63% reduced inflows. Impact on irrigated agricultural production and profitability are estimated with a mathematical programming model using a two‐stage approach that simultaneously estimates short and long‐run adjustments. The model accounts for a range of adaptive responses including: deficit irrigation, temporarily following of some areas, permanently reducing the irrigated area and changing the mix of crops. The results suggest that relatively low cost adaptation strategies are available for a moderate reduction in water availability and thus costs of such a reduction are likely to be relatively small. In more severe climate change scenarios greater costs are estimated. Adaptations predicted include a reduction in total area irrigated and investments in efficient irrigation. A shift away from perennial to annual crops is also predicted as the latter can be managed more profitably when water allocations in some years are very low.     

A note on the socio-economic composition of the inner city

This paper considers the socio-economic structure of the inner area of Newcastle upon Tyne, in an attempt to contrast notions of a cycle of deprivation and the “housing trap” thesis. The use of discriminant analysis suggests that there exists no concentration of low-income groups within the inner city. The relationship between multiple deprivation and resource provision is examined with respect to this finding.

Competitive Effects of Disclosure in a Strategic Entry Model

We investigate the welfare consequences of incumbent firms' mutual disclosure of cost information when there is a threat of entry from a firm not required to disclose its private cost information. New effects of disclosure are observed relative to no-entry models, with the result that incumbents' expected output is a decreasing function of the disclosure level. However, further analysis shows that increased disclosure usually increases incumbent expected profits and decreases expected consumer surplus, despite the additional entry effect of disclosure. Such analytical derivations provide objective input to the FASB as they attempt to predict the competitive effects of changing mandated disclosure requirements.     

Acculturation and the influence of ethnicity on market orientation of African and Caribbean companies in Britain

Since acculturation is the process of acquiring the customs of an alternative society we assume that adapting to consumers from various cultures will be a fundamental task for African and Caribbean (A&C) companies in Britain. This study investigates market orientation of A&C service companies and their processes of cultural learning and adaptation using ethnicity as a basis for an exploratory study of the British market. The findings indicate that A&C companies serve as bicultural mediators, both accommodating their consumers and working to alter their consumption patterns to bring them into line with their own ethnic and British national market customs. The adaptation of A&C service companies to the cultural characteristics and needs of their customers results in changes to their companies, consumers and the British marketplace.     

Foreign Direct Investment in China: An Examination of the Literature

Since 1978, when China announced its ‘open-door’ policy to pursue the country's long-term national goal, the Four Modernisations, more than 220,000 foreign funded ventures have been approved. By the end of 1994 some US$300 billion of contracted investment had been agreed and US$95 billion of utilized investment, making the country the most important recipient of foreign direct investment (FDI) in the developing world. This paper analyses the phenomenon of FDI in China. It examines the different forms and composition of FDI, reviewing its development since the early days of the ‘open-door’ policy and analysing its importance for Chinese domestic and export industries, as well as Western investor companies. Furthermore, the paper focuses on the world-wide sources of FDI in China and its distribution by both region and industry. Additionally, it reviews the existing research on FDI in China, emphasizing the investment mode of equity joint venture.
