Characterizations of negative multinomial distributions based on conditional distributions

In this paper characterizations of negative multinomial distributions based on conditional distributions have been studied.     

Losers and prospectors in the short-term options market

Intraday data for weekly options are investigated for behavioral biases implied in prospect theory (PT) and cumulative prospect theory (CPT). The results generally support both theories, with losers (winners) observed to be relatively risk-seeking (averse). On aggregate, losers (winners) overprice (underprice) their contracts and overweight (underweight) the probability of winning. Additionally, the volatility smirk observed in equity options is dampened by PT/CPT biases. The price distortions are time sensitive, especially for losing traders. Losers hold out by transacting later in the day and closer to expiration than their baseline counterparts. This betting-time effect is absent among winners.     

Dominant markets,staggered openings,and price discovery

This study examines information incorporation and price discovery in closely related markets that witness staggered openings. A theoretical model is presented. In this framework, one market, termed dominant, is the venue where most of the price discovery occurs, and the other is termed secondary. The model predicts heightened volatility and order flow in each market when it opens first compared with when it opens second. The effects are predicted to be more pronounced in the dominant market, and is linked to the process of information incorporation. Tests conducted using futures on crude oil (dominant) and gasoline (secondary), two related markets that witness staggered openings, reveal findings consistent with the model's predictions. © 2010 Wiley Periodicals, Inc.

The effect of media,product and message factors on ad persuasiveness: the role of affect and cognition

The effects of media, product and advertising strategy variables on consumers' thoughts and feelings are investigated. Both direct and indirect paths from the advertising variables to ad persuasiveness measures are also analysed with the indirect paths leading through affective and cognitive responses. Two hundred and forty television and magazine ads are analysed with respect to advertising variables, affect, cognition and ad persuasiveness. Results indicate that advertising variables are indirectly linked to ad persuasiveness with the indirect path occurring through affective and cognitive responses.     

The moderating roles of shopper experience and store type on the relationship between perceived merchandise value and willingness to pay a higher price

In the retail domain, we consider the moderating influence of shopper experience (high versus low experience) and store type (high- versus low-priced stores) on a model that identifies three distinct routes (economic, affective and informational) from perceived merchandise value to willingness to pay a higher price. Each route accounts for a different outcome arising from merchandise value and leading to willingness to pay a higher price. Analyses of data obtained from a sample of 600 shoppers at four grocery stores provide results for specific hypotheses related to each moderator and each distinct route. The results of multiple sample analyses show that the economic route is stronger for high experience shoppers as well as for high-priced stores. Findings pertaining to hypotheses for moderation of both the affective and informational routes are mixed. We discuss the importance of these findings for retail managers as well as for future research.     

Characterization of Normal Distribution Related to Two Samples Based on Regression

Characterization of normal distribution related to two samples based on second conditional moments has been obtained. This characterization has been transformed to a characterization based on the UMVU estimators of the density function. These results are generalized to k samples from normal distributions. Finally applications of these characterization results to goodness-of-fit test are discussed.     

A product Pareto distribution

The Pareto distributions are becoming increasing prominent in several applied areas. In this note, a new Pareto distribution is introduced. It takes the form of the product of two Pareto probability density functions. Various structural properties of this distribution are derived, including its cumulative distribution function, moments, mean deviation about the mean, mean deviation about the median, entropy, asymptotic distribution of the extreme order statistics, method of moments estimates, maximum likelihood estimates and the Fisher information matrix. The calculations involve the use of several special functions.     

Gender pay differentials during the transition in Poland*

This paper assesses the relative economic welfare of women during the transition in Poland. After providing an account of gender differences in several labour market outcomes we analyse the male‐female wage differential over the period 1993–97. We find that there is almost no change in the wage gap, that most of the explained portion of the wage gap may be attributed to industrial and occupational segregation, and that a substantial portion of the wage gap remains unexplained. We briefly discuss possible socio‐economic explanations for our findings.     

Guard labor

We explore the economic importance of the private and public exercise of power in the execution of contracts and defense of property rights. We define power and represent it in a model of growth in a modern capitalist economy, borrowing themes from the classical economists (unproductive labor, profit-driven investment), Marx (the labor disciplining effect of unemployment), and the contemporary theory of incomplete contracts (the role of monitoring and enforcement rents). We use this model to identify the resources devoted to the exercise of power, which we term guard labor as we measure these in labor units. Data from the United States indicate a significant increase in its extent in the U.S. over the period 1890 to the present. Cross-national comparisons show a significant statistical association between income inequality and the fraction of the labor force that is constituted by guard labor, as well as with measures of political legitimacy (inversely) and political conflict. Some observations on the welfare implications of guard labor conclude the paper.
