Psychological research documents that individuals are more likely to resort to superstitious practices when operating in environments dominated by uncertainty, high stakes, and perceived lack of control over the outcomes. Based on these findings, we suggest that the stock market represents an ideal breeding ground for superstition and then test whether superstition-induced behavior affects inve...

We examine whether institutional investors, and specifically underwriters, have an information advantage over other market participants in new public companies. We focus our attention on a sample of publicly traded firms that have become the target of an IPO-related securities class action lawsuit filed under Section 11 of the 1933 Securities Act between January 1991 and December 2006 and a mat...

We develop and implement a rigorous analytical framework for empirically evaluating the relative performance of firm-level expected-return proxies (ERPs), based on the premise that superior proxies should closely track true expected returns both cross-sectionally and over time (that is, the proxies should exhibit lower measurementerror variances). We then compare five classes of ERPs nominated ...

Investments in socially responsible investments (SRI) are still a small, but growing segment of international capital markets. This study analyses whether a SRI screening process applied to equities results in a different performance outcome compared to relevant conventional benchmark indexes. In contrast to other studies, the analysis concentrates on SRI indexes and not on investment funds. Th...

The authors study time-variation in the co-movements between daily stock and Treasury bond returns over 1986 to 2000. Their innovation is to examine whether variation in stock-bond return dynamics can be linked to non-return-based measures of stock market uncertainty, specifically the implied volatility (IV) from equity index options and detrended stock turnover (DTVR). The authors investigate ...

A microtiter plate hybridization-based PCR-enzyme-linked immunosorbent assay (PCR-ELISA) has been used for the detection and identification of a variety of microorganisms. Here, we report the development of a PCR-ELISA for the identification of clinically relevant human rotavirus VP7 (G1 to G6, G8 to G10, and G12) and VP4 (P[4], P[6], P[8], P[9], and P[14]) genotypes. The G and P types of refer...

-Wheat is the most important crop of many countries including Pakistan. Assessment of Yield stability of wheat in different environments has been an important issue for wheat growers and horticulturists. In present paper yield stability of wheat genotypes is assessed at different research institutions/stations across the country using univariate parametric stability models and interrelationship...

Palmitoylated proteins contain a 16-carbon saturated fatty acyl group that is post-translationally attached by a labile thioester bond. These modified proteins are mainly membrane-bound; the lability of the thioester bond allows the process to be reversible, a unique property of this modification. We report here that the gene for G14, located in the class III region of the human MHC, encodes a ...

Twenty five advanced lines among them twelve lines obtained from the cross between Edible Podded Pea and IPSA Motorsuty-1, nine obtained from the cross between Local White and IPSA Motorsuty-3 and five parental lines were included to measure genetic diversity. The field experiment was conducted at the research farm, Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur, Bangladesh....

The behavior of agents in financial markets often displays biases or errors; for example, agents frequently do not compute probabilities correctly. However, we argue that these biases/errors are not always reflected in prices. In particular, we hypothesize that agents who make errors in computing probabilities lose confidence in their probability estimates when they face market prices that are ...
