Larry Moss and the Struggle Against Racism by the Whately Professors of Political Economy

In this note, we highlight an important consideration of Larry Moss's life's work, the continual struggle within economics against racism. Larry initiated and supported the symposium on eugenics published by the American Journal of Economics and Sociology in July 2005. He edited the volume Social Inequality, Analytical Egalitarianism and the March Toward Eugenic Explanations in the Social Sciences in August 2008. These constitute obvious signs of Larry's concern.
He conjectured that the Trinity College Dublin political economists who held the Whately professorship should be thought of as a school. Such a school was in fact identified in 1850 by an outsider who pointed to their shared opposition to racial explanations within an institutional setting. That shared opposition allowed them to speak against the narrow interests of the rulers of the country. Of course, other political economists of the time, Mill in particular, were also emphatic in their anti-racism. Thus, not only do we need to take up Larry's challenge to describe the Trinity College school but we must also seek its connections with the Scottish-English group of anti-racists.     

Some properties of the minimum and the maximum of random variables with joint logconcave distributions

It is shown that if (X ₁, X ₂, . . . , X _n ) is a random vector with a logconcave (logconvex) joint reliability function, then X _P = min _i∈P X _i has increasing (decreasing) hazard rate. Analogously, it is shown that if (X ₁, X ₂, . . . , X _n ) has a logconcave (logconvex) joint distribution function, then X ^P  = max _i∈P X _i has decreasing (increasing) reversed hazard rate. If the random vector is absolutely continuous with a logconcave density function, then it has a logconcave reliability and distribution functions and hence we obtain a result given by Hu and Li (Metrika 65:325–330, 2007). It is also shown that if (X ₁, X ₂, . . . , X _n ) has an exchangeable logconcave density function then both X _P and X ^P have increasing likelihood ratio.     

Young children’s learning of water physics by constructing working systems

The present study explored young 5–6-year old children’s design-based learning of science through building working physical systems and examined their evolving conceptions of water flow. Fifteen children in an experimental group individually built water-pipe systems during four sessions that included end-of-session interviews. In addition, they were interviewed with a pretest and posttest. The interviews consisted of near and far transfer tasks testing for the children’s understanding of three physical rules of water flow and their combined application. To control for testing, maturation and familiarity with the interviewer, a control group was interviewed as well. It was found that through building, the experimental group children’s understanding of the related physical rules grew substantially, showing a strong effect size. Moreover, the builders demonstrated budding abilities in coordinating two physical rules. Three distinct conceptual models regarding water flow were found: water can flow along a path disregarding height considerations; water can only flow downwards; and a coordinated view combining gravitational considerations and equilibration within connected vessels. The children’s new understandings were found to be local, fragile and bound by developmental constraints. The control group but not the experimental group learned one of the physical rules in the far transfer tasks. The merits and limits of learning science through designing and constructing working physical devices are discussed.     

Employee commitment in MNCs: Impacts of organizational culture,HRM and top management orientations

This article tests a model of organizational commitment in multinational corporations (MNCs). According to the model, organizational culture and human resource management (HRM) affect employee commitment directly as well as indirectly through top management team orientations. Szpecifically, we examined the effect of top management team global orientation and geocentric orientation, which are seen as contributing uniquely to employee commitment in MNCs. The model was tested on a sample of 1664 core employees working in 39 affiliates of 10 MNCs. We found strong overall support for the model. In particular, organizational culture characterized by high adaptability and a HRM system characterized by high performance work practices were found to have a significant and direct effect on employee commitment. In addition, we found that the effect of these traditional elements of the human organization is partially mediated through top management orientations, specific to international firms. The validity and generalizability of these results are reinforced by the control of a set of demographic variables as well as nationality of parent company.     

Stochastic orderings of convolution residuals

In this paper we study convolution residuals, that is, if $X_1,X_2,\ldots ,X_n$ are independent random variables, we study the distributions, and the properties, of the sums $\sum _{i=1}^lX_i-t$ given that $\sum _{i=1}^kX_i>t$ , where $t\in \mathbb R $ , and $1\le k\le l\le n$ . Various stochastic orders, among convolution residuals based on observations from either one or two samples, are derived. As a consequence computable bounds on the survival functions and on the expected values of convolution residuals are obtained. Some applications in reliability theory and queueing theory are described.     

Theories of choice under risk: Insights from financial markets

To date, the plausibility of theories of choice under risk hinges are mainly on experimental evidence. This paper devises and implements an approach amenable of assessing the performance of three families of models (expected utility, rank-dependent expected utility, and the cumulative prospect theory) using information from financial asset markets. Our findings unequivocally support reference-point dependence, diminishing marginal sensitivity, loss aversion, and nonlinear weighting of (gain and loss) physical probabilities. The empirical observations are found to be robust to, inter alia, the parameterization of the utility and probability weighting functions, “day-of-the-week effects”, the choice of a reference point, and the introduction of possible, low-probability market crashes (peso component).     

Congestion games with load-dependent failures: Identical resources

We define a new class of games, congestion games with load-dependent failures (CGLFs). In a CGLF each player can choose a subset of a set of available resources in order to try and perform his task. We assume that the resources are identical but that players' benefits from successful completion of their tasks may differ. Each resource is associated with a cost of use and a failure probability which are load-dependent. Although CGLFs in general do not have a pure strategy Nash equilibrium, we prove the existence of a pure strategy Nash equilibrium in every CGLF with nondecreasing cost functions. Moreover, we present a polynomial time algorithm for computing such an equilibrium.     

Emerging Issues in Retailing Research

Retailing practice and the research resulting have experienced significant changes in recent years. This article reflects on Journal of Retailing articles published during our editorial tenure (2002–2007). Although Journal of Retailing publishes articles on many retailing topics, they have chosen four categories that they believe has had the largest impact on retailing research during that time, and the potential for the greatest contribution in the future: Growth of the Internet and e-commerce; branding and customer loyalty; service success strategies; and behavioral issues in pricing and patronage. Several illustrative studies are highlighted in each category, and directions for future research are provided.     

Total factor productivity growth in banking: The Israeli banking sector 1979–1982

The primary focus of this paper is the modeling and estimation of total factor productivity growth in banking. The measured total factor productivity growth is decomposed into its main components: 1) scale economy and output growth, 2) branching effect, and 3) technological change effect. Our findings indicate that total factor productivity grew at an annual average rate of 7.8% for the 1979–1982 period but this growth has slowed down to only 2.9% for the 1981–1982 period. Scale economy and output growth have contributed to about four-fifths of the growth, whereas branch growth and technical change have contributed to one-fifth of the growth. An important observation is the increasing importance of both branch growth and technical change throughout the period, especially for smaller banks.The refereeing process of this paper was handled by J. van den Broeck.
