The seasonal patterns observed on Monday stock returns are still unexplained by different asset pricing models. We attempt
to fill this gap in the finance literature by using the Fama-French (Journal of Financial Economics 33:3–56, 1993) risk factors to explain the Monday seasonal. The results in the study show that Monday returns are explained by risk factors
such as the market return, the size of the firms, and the book-to-market ratios of firms. 相似文献

Joint space multidimensional scaling maps are often utilized for positioning analyses and are estimated on survey samples
of consumer preferences, choices, considerations, or intentions so as to provide a concise spatial depiction of the competitive
landscape including relevant dimensions or attributes, competing brands, and consumers in the same joint space representation.
Care has to be given concerning the underlying scale properties of such survey data so as not to distort the resulting joint
space positioning map. We present a new joint space multidimensional scaling procedure for positioning analyses for displaying
the structure in such survey data when such common ordered successive category measurement scales such as Likert, Edwards,
semantic differential, etc., are employed. We present the technical details of this stochastic ordered preference multidimensional
scaling vector model as well as the maximum likelihood estimation-based algorithm devised for parameter estimation. Favorable
comparisons are made with several existent multidimensional scaling methods in representing the internal structure for such
data in marketing positioning studies. An actual commercial positioning application concerning large sports utility vehicles
consideration to buy judgments is presented with predictive validation comparisons with other multidimensional scaling joint
space procedures. 相似文献

This paper analyzes the implications of joint production for the four basic results of the factor-endowments theory of international trade. The nature of the relationship between commodity prices and factor rewards is first elucidated in detail. It is then shown that, in sharp contrast to prevalent opinion, there is in fact a strong presumption that the basic theorems will continue to hold in essence. The paper then considers applications and extensions of the analysis to higher dimensions. 相似文献

The study adds to the existing literature on the relationship between output and unemployment by using a sectoral specification of Okun’s Law to capture the differential sensitivity of the unemployment rate to output developments in the services and manufacturing sectors. Using quarterly data for the period between 2000 and 2012, we show that Malta’s unemployment rate has been more sensitive to output developments in the services sector than to those in the manufacturing sector. We use different equation specifications and the youth unemployment rate to show that the impact resulting from developments in the manufacturing sector occurs mainly via lay-offs while developments in the services sector affect the unemployment rate via the hiring of new entrants into the labour market. 相似文献

An adverse selection model is utilized to demonstrate that informational asymmetry may make it wealth optimal for the financial intermediary (FI) to credit ration and to rationalize the existence of different lenders in the credit market. The crucial assumption is that borrowers differ in their tolerance for a lender-imposed default penalty, the severity of which also varies with the lender. The credit rationing portion proves that the FI will: 1) be forced by a binding regulatory constraint to overinvest in capital; 2) ration its worst risk class borrowers; 3) establish its optimal loan interest rate on the basis of the average quality of its loans and the interest rate elasticity of the borrower demand in its best risk category; and 4) decrease the total loan volume and increase the loan interest rate due to an increase in the capital requirement, but the effect on the default risk quality of its loan portfolio is ambiguous. The existence result is that if a lender has a high default penalty, he can charge a lower rate and attract only “good” borrowers, i.e., heterogeneous lender types encourage the screening of borrowers and vice versa. 相似文献

Colleges and universities in the US differ markedly in their access to economic resources. National data are used here to describe the resulting hierarchy that's reflected in schools' spending on their students, the prices those students pay, and the subsidies they get in consequence. Both historical data and projections based on recent institutional saving suggest that economic disparities among institutions and their students are increasing. In a final section, the paper asks what to make of this: what we can say about the right degree of institutional disparity – whether we have too much, too little, or about the right amount of differentiation. 相似文献
