Demand for product characteristics is examined within the context of models that allow for both corner and interior solutions corresponding to zero and non-zero demand. Product attribute information is associated with marginal utility and curvature (satiation) parameters of various utility functions. Empirical applications demonstrate the need for incorporating characteristics in a fairly general way. We also compare our approach to an ideal point and pure Lancasterian versions of our nonlinear utility model. The data support our model over either the ideal point or Lancasterian variants. 相似文献

This paper examines funding issues for UK Technology-based Small Firms (TBSFs). TBSFs are the cry of today and UK government
like other countries is trying to increase the mass of TBSFs by various means. However, it is reported that TBSFs face many
impediments to their successful development. Finance is believed as the main barrier at the early stages of TBSFs development.
This paper is attempting to follow up and report if the funding situation for UK TBSFs has improved. The findings reported
in this paper suggest that nearly 80% sample firms were finance constrained at the early stages of business development. 相似文献

Research into the capital structure of firms has been the subject of extensive empirical investigation but further progress may be constrained by the conventional paradigm underlying most of this work. This paper seeks to extend the debate by examining the endogenous influence of corporate strategy on financing decisions made by firms. While the theoretical specification of the possible relationship has to be developed further, various models were constructed and company data from Australia, an economy with some notoriety for fairly loose corporate debt management, was used to examine various hypothesized relationships. Our analysis suggests that corporate strategy influences capital structure, particularly for the most diversified firms, and that the emerging relationship is complex. Profit, cash flow, the rate of growth and the level of earnings risk are important additional internal influences on capital structure. The results are reasonably robust and indicate that this focus of enquiry has considerable potential for further resolution of the capital structure puzzle, as well as contributing to the debate on the impact of institutional shareholders on the corporate strategy of the firms in which they invest. 相似文献

Many of the key macro-economic and financial variables in developed economies are characterized by permanent volatility shifts. It is known that conventional unit root tests are potentially unreliable in the presence of such behaviour, depending on a particular function (the variance profile) of the underlying volatility process. Somewhat surprisingly then, very little work has been undertaken to develop unit root tests which are robust to the presence of permanent volatility shifts. In this paper we fill this gap in the literature by proposing tests which are valid in the presence of a quite general class of permanent variance changes which includes single and multiple (abrupt and smooth-transition) volatility change processes as special cases. Our solution uses numerical methods to simulate the asymptotic null distribution of the statistics based on a consistent estimate of the variance profile which we also develop. The practitioner is not required to specify a parametric model for volatility. An empirical illustration using producer price inflation series from the Stock–Watson database is reported. 相似文献

Abstract
Aims
To characterize a US population of patients with irritable bowel syndrome with constipation (IBS-C) or chronic idiopathic constipation (CIC) using CONTOR, a real-world longitudinal research platform that deterministically linked administrative claims data with patient-reported outcomes data among patients with these conditions. 相似文献30.
We investigate the ability of disclosed operating cash flow and indirect accruals components to explain annual returns for a sample of Australian firms. Consistent with claims made by accounting standard setters, we find evidence of significant explanatory power for disclosed operating cash flow components beyond aggregate operating cash flows when they also have significant incremental predictive power for future (one year ahead) operating cash flows. Accrual components also have incremental explanatory power for returns. In addition, we find evidence of significant explanatory power for operating cash flow components beyond estimates of the components (based on other financial statement disclosures) for firms with large differences between disclosed and estimated components. 相似文献
