Past parametric tests of demand system rank employed polynomial Engel curve systems. However, by Gorman's ( 1981 ) theorem, the maximum possible rank of a utility‐derived polynomial demand system is three. The present paper proposes a class of demand systems that are utility derived, are close to polynomial, and have rank four. These systems nest rational polynomial demands, and so can be used to test ranks up to four. These systems are suitable for applications where high rank is likely, such as demand systems involving a large number of goods. A test of rank using this new class of systems is applied to UK consumer demand data. Copyright © 2002 John Wiley & Sons, Ltd. 相似文献

We propose a new model to estimate the term structure of interest rates using observed on‐the‐run Treasury yields. The new model is an improvement over models that require a priori knowledge of the shape of the yield curve to estimate the term structure. The general form of the model is an exponential function that depends on the estimation of four parameters fit by nonlinear least squares and has straightforward interpretations. In comparing the proposed model with current yield‐curve‐smoothing models, we find that, for the data used, the proposed model does best overall in terms of pricing accuracy both in sample and out of sample.

We study the structure of household portfolios of financial wealth by analyzing both the determinants of total financial wealth and the choice between risky (stocks and bonds) and riskfree assets (saving accounts). The econometric specification is a generalized trivariate Tobit model, estimated on a cross section of 3,077 households in the Netherlands in 1988. We account for endogeneity of financial wealth and for selectivity due to nonreporting. Results show that the level of financial wealth and the marginal tax rate are major determinants of the allocation between riskfree and risky assets. 相似文献

Forecast improvement is often approached by attempting to find the “best” model for a given situation. Less attention has
been paid to the possibility of examining past prediction errors for patterns that may suggest forecast adjustments for the
future. This empirical study involves one firm’s management judgment forecasts for product sales and the attempts made to
improve their accuracy by removing certain types of bias. In three of the five series examined, error reduction averaging
close to thirty percent occurs as a result of the adjustment procedure. The other two series proved to be relatively free
from bias and were therefore not in need of the correction method described. 相似文献

Various claims have been made about the causes of the Asian crisis and its spread. Here, we use data on the behaviour of capital flows during the crisis to test the strong forms of four such hypotheses, that portfolio investors and hedge funds played a dominant role in initiating and/or spreading the crisis; that moral hazard kept efficient markets from predicting the crisis; and, finally, the common lender hypothesis of Kaminsky and Reinhart. In the process we also test implications of the Calvo-Mendoza model of rational investor ignorance. All are falsified as monocausal explanations. For example, portfolio investments that could not have been subject to substantial moral hazard continued to flow into Asia until very shortly before the crisis. Likewise, banks were a much larger source of capital outflows during the crisis than were portfolio investors. While falsified in their strongest forms, several of these hypotheses in less strong forms should play a role in a more nuanced analysis. It is necessary to move past simple single-factor approaches in order to produce a more complete, synthetic explanation of this episode. 相似文献

In this paper we investigate the effect of golden parachute (GP) adoptions on shareholder wealth. We control for the potential effect a GP adoption has on the probability that a firm will receive a takeover bid by investigating the wealth effects for firms that are in play when the GP is adopted. We find that announcements are wealth neutral when firms are in play and wealth increasing when firms are not in play when a GP is adopted. The results suggest that GPs have no influence on the success of a tender offer, refuting the hypotheses that they either align manager and shareholder interests or that they entrench inefficient managers. The difference in the results for in-play and not-in-play firms is consistent with the hypothesis that GPs signal an increased likelihood that a firm will receive a takeover bid. 相似文献

Background risk can influence the performance of insurance markets that must deal with adverse selection when applicants are risk vulnerable, since they are more averse to bearing the insurable risk as a result of their exposures to background risk. We show that background risk always results in a lower deductible for the incentive constrained contract, and that a broader range of markets attains the stable sequential equilibrium cross-subsidized pair of separating contracts. We conclude that background risk always improves the performance of markets for coverage against (insurable) foreground risks that must deal with adverse selection. We also find, however, that these improvements are never sufficient to offset the cost to insureds of bearing the background risk. 相似文献

This paper has grown out of a long standing personal concern that the current approaches to design teaching are too narrowly based and that they can distort the very activity that they set out to encourage. A survey of the comments made in Examiner's Reports of pupil's work in public design examinations during 1986 & 1987 provides some insight into the difficulties that pupils experienced in carrying out their design activities.Design activity in schools developed from the beginnings initiated by the curriculum development projects of the late 1960's and early 1970's. These put forward methodical approaches to designing which have become widely used in UK secondary schools and which are now firmly embedded in the publications and project assessment framework of the current national examinations.The present study suggests that, while these methodical approaches clearly work, they imply a logical progression of thought which does not necessarily parallel the pattern of human thinking. It is recognised that pupil's design folios written up at the end of a project can be made to describe a logical, systematic procedure which has more to do with the assessment framework than the actual developments of design ideas during the project. Indeed, teachers and candidates were being actively encouraged to base their work on these structured frameworks:The actual style and quality of the folder presentation is also important. This is particularly so when working to a detailed mark scheme. Certainly it is easier to mark a folder which broadly follows the pattern of the mark scheme than one which is very erratic. Teachers are advised as to the advantages of using the mark scheme as a teaching tool and as a guide for folder presentation. NEA, 1986.Finally, the paper examines some more recent developments in the procedural models of design activity and the way in which professional designers approach their work. These insights provide an indication of the way forward for school design work and its assessment. 相似文献

Strategic rationality is subjected here to natural selection. In a zero-sum repeated game of incomplete information, one long-run individual is informed of the state of the world, and plays against a sequence of short-run opponents who are not. Strategies are noisy and have bounded recall. An equilibrium in these is shown to exist. Relative to any such equilibrium, sufficiently greater recall enjoys an advantage that is not decreasing in the original level of recall, thus capturing the Red Queen effect. The selection pressure to reduce a small amount of noise is less than that to increase recall. 相似文献
