There are two variance components embedded in the returns constructed using high frequency asset prices: the time-varying variance of the unobservable efficient returns that would prevail in a frictionless economy and the variance of the equally unobservable microstructure noise. Using sample moments of high frequency return data recorded at different frequencies, we provide a simple and robust technique to identify both variance components. 相似文献

Doing qualitative field research in management accounting: Positioning data to contribute to theory 总被引:2,自引:0,他引:2
In this paper we argue that theory, method, methodology, and knowledge gains in qualitative field studies are intertwined through the ongoing hypothesis development in the field. We develop our argument through a discussion of specific qualitative field studies in management accounting. We emphasise in particular the distinctive role of theory in qualitative research as relating to expression of a subjective reality more than clarification of an objective one. In considering this subjectivity we discuss the ways in which the doing of qualitative research brings to bear discipline on the researcher allowing us to assess the trustworthiness of their accounts. The intention is to develop a more appropriate basis for judging the plausibility of qualitative field studies than notions borrowed from positivistic methodology. 相似文献

Models that assume only consumer tastes determine the characteristics of supply are restrictive; producers can gain utility from aspects of production and pay for deviating from demand by accepting lower financial returns. We model and measure motivations of California winery owners, and analyze their effects on quality and price. We find utility–maximizers are more likely to produce high quality and set higher quality–adjusted prices. Profit–oriented owners are less likely to produce high quality wines. These results suggest that the presence of hobbyists who enjoy producing high quality may lower financial returns in the segment and discourage profit–maximizers from locating there. 相似文献

Drawing on qualitative data collected during semi-structured interviews with 36 profit centre managers in manufacturing firms in Victoria, Australia, this study seeks to explore the mechanisms used to manage multiple manufacturing performance dimensions arising from the pursuit of profit centre strategy. Where measures capture potentially conflicting influences on the manufacturing cost function, strategy implementation is facilitated by loosening control reactions to cost variances and through explicit attempts to integrate multiple measures. However, a joint emphasis on performance dimensions relating to manufacturing efficiency and customer responsiveness emerges as problematic. In contrast, a joint emphasis on quality and efficiency is relatively easily managed. It is suggested that in the context of responsiveness strategies, the difficulty of designing complete measures inhibits the effectiveness of performance measurement systems as a facilitator of strategy implementation. 相似文献

We emphasize the role of accounting policies, and their audit, in an earnings management setting. We use a two–period agency in which three frictions interact: the agent privately observes action (or effort) supply and output, and the initial contract is subject to renegotiation. This creates a setting in which both players' behavior is of concern, and, importantly, information rationing is efficient. Moreover, this information rationing is directly interpretable as being produced by an accounting policy whose application is ensured by an auditor. 相似文献

This paper reports on a questionnaire survey about share valuation practices among investors and their intermediaries in Saudi Arabia. The findings suggest that fundamental analysis is used most by investor respondents where a P/E multiple is applied to an earnings forecast to generate a prediction of future price. However, technical analysis is also used to a much greater extent than in developed markets. Finally, the results indicate that quarterly and annual reports as well as newspapers are widely consulted by investors when forming their expectations about share valuations. 相似文献

An issue in the pricing of contingent claims is whether to account for consumption risk. This is relevant for contingent claims on stock indices, such as the FTSE 100 share price index, as investor’s desire for smooth consumption is often used to explain risk premiums on stock market portfolios, but is not used to explain risk premiums on contingent claims themselves. This paper addresses this fundamental question by allowing for consumption in an economy to be correlated with returns. Daily data on the FTSE 100 share price index are used to compare three option pricing models: the Black–Scholes option pricing model, a GARCH (1, 1) model priced under a risk-neutral framework, and a GARCH (1, 1) model priced under systematic consumption risk. The findings are that accounting for systematic consumption risk only provides improved accuracy for in-the-money call options. When the correlation between consumption and returns increases, the model that accounts for consumption risk will produce lower call option prices than observed prices for in-the-money call options. These results combined imply that the potential consumption-related premium in the market for contingent claims is constant in the case of FTSE 100 index options. 相似文献

Replacement investment is essentially a regenerative optimal stopping problem; that is, the key decision concerns when to terminate the life of existing plant – and hence when to start over again. This paper examines this optimisation problem within a continuous time framework and studies the qualitative and quantitative impact of uncertainty on the timing of new investment (and the criteria that should be used for terminating the life of existing plant). 相似文献

As the elderly population of the United States grows in absolute number and as a proportion of total population, accurate projections of that population become increasingly important for sound policy decisions. Cohort component techniques are typically used for state and local projections of the elderly population, but are often outdated or even nonexistent for many local areas. This paper suggests an alternative approach, based on Medicare data and simple projection techniques. Projections for several base periods and projection horizons are made for all states and for counties in Florida and are compared with actual Medicare enrollment. On the basis of these comparisons it appears that Medicare data and simple projection techniques can produce very useful short-run projections of the elderly population for states and local areas. 相似文献
