We evaluate the virial coefficients Bk for k ≤ 10 for hard spheres in dimensions D = 2, · · · , 8. Virial coefficients with k even are found to be negative when D ≥ 5. This provides strong evidence that the leading singularity for the virial series lies away from the positive real axis when D ≥ 5. Further analysis provides evidence that negative virial coefficients will be seen for some k > 10 ...

Long historical averages of real earnings help forecast present values of future real dividends. With aggregate U.S. stock market data (1871-1986), a vector-autoregressive forecast of the present value of future dividends is, for each year, roughly a weighted average of moving-average arnings and current real price, with between two thirds and three fourths of the weight on the earnings measure...

Prior research demonstrates that investors respond differently to earnings surprises that are part of a string of consecutive earnings increases or surprises than to those that are not. To shed light on who values these patterns, I compare trading responses of small and large traders to earnings surprises that occur during a series of positive or negative surprises. I find that the relative int...

This paper gives a qualitative description how Young tableaux can be used to perform a Clebsch-Gordan decomposition of tensor products in SU(3) and how this can be generalized to SU(N).

This essay describes the development of groups used for the specification of symmetries from ordinary and magnetic point groups to Fedorov and magnetic space groups, as well as other varieties of groups useful in the study of symmetric objects. In particular, we consider the problem of some incorrectness in Vol. A of the International Tables for Crystallography. Some results of tensor calculus ...

In random coefficients linear IV models, fixed effects averages of the individual-specific coefficients are biased in short panels due to the finite-sample bias of IV estimators. This paper introduces a new class of bias-corrected semiparametric estimators for panel models where the response to the regressors can be individual-specific in an unrestricted way. These estimators are based on momen...

this paper takes fundamental analysis research beyond the spatial and temporal bounds of previous studies. it was investigated that how detailed financial statement data enter the decisions of market makers by examining how current changes in the fundamental signals chosen can provide information on subsequent earnings changes. using tehran stock exchange’s firms data from 2003 to 2012, the rol...

R research has shown that managers in publicly traded companies facing earnings pressure—the pressure to meet or beat securities analysts’ earnings forecasts—may make business decisions to improve short-term earnings. Analysts’ forward-looking performance forecasts can serve as powerful motivation for managers, but may also encourage them to undertake short-term actions detrimental to future co...

Russia provides an interesting context for studying the labor market experiences of the elderly because of its experience with market transition, its looming growth in the elderly dependency ratio, and its unusual pension policies that do not penalize pensioners for working. We use data from twenty surveys of the Russian population conducted from February 1991 to November 2007 to analyze the la...
