Marketing researchers have documented significant biases in estimated price elasticity's from brand choice models that ignore state dependence effects. Yet empirical research on firm behavior has thus far ignored the effects of state dependence. In this paper, one investigates the supply side consequences of ignoring state dependence using household-level data...
This paper describes a method for estimating insurance claims or risk premiums allowing for spatial dependence as well as explanatory factors. The concepts are related to those used for graduation of mortality tables using cubic splines but extended to spatial dependence as found in many insurance products. Firstly techniques for...
This white paper presents a framework for applying memoization selectively. The framework provides programmer control over equality, space usage, and identification of precise dependences so that memoization can be applied according to the needs of an application. The paper describes the framework in the context of a functional language and...
Asymmetric dependence in buyer-seller relationship is probably among the most widely studied phenomena in relationship research. However, the focus on asymmetric resource dependence has mainly addressed risks within the buyer-seller dyad and has largely disregarded external types of risk affecting relationships. This paper examines how to balance resources in relationships...
The paper considers three sets of phenomena that feature prominently and separately in the financial economics literature: conditional mean dependence or lack thereof in asset returns, dependence and hence forecastability in asset return signs and dependence and hence forecastability in asset return volatilities. It shows that they are very much...
This paper uses the tests of Robinson (1994a) to analyse the degree of dependence in the intertemporal structure of daily stock returns (defined as the first difference of the logarithm of stock prices, where the series being considered is the S&P500 index). These tests have several distinguishing features compared with...
This Transportation Energy Survey Data Book examines public concern about U.S. dependence on imported oil, public assessment of the energy situation in the United States, and perceived effects of gasoline prices on individuals and households. In addition, this paper also focuses on public expectations and federal government actions that can...
This article considers three sets of phenomena that feature prominently and separately in the financial economics literature: conditional mean dependence or lack thereof in asset returns, dependence and hence forecastability in asset return signs with implications for market timing, and dependence and hence forecastability in asset return volatilities. It shows...
This white paper deals with a two-step modeling approach that is developed for single-event transients in linear circuits that uses the PISCES device simulation program to calculate transient currents in key internal transistor structures. Those currents are then applied at the circuit level using the SPICE circuit analysis program. The...
Modern risk management calls for an understanding of stochastic dependence going beyond simple linear correlation. This paper deals with the static (non-time-dependent) case and emphasizes the copula representation of dependence for a random vector. Linear correlation is a natural dependence measure for multivariate normally and, more generally, elliptically distributed risks...
DESPITE an upsurge in human resource development HRD activities in organisations, training departments are still hard put to justify their usefulness and importance to their employers. Part of the reason is that the proliferation of HRD activities has blurred the distinction between what is truly needed by the organisation to...
[ILLUSTRATION OMITTED] A BRAND is the expectations, image, and perceptions it creates in the minds of others, when they see or hear a name, product or logo. Microsoft, Nike, Toyota, Volvo, and Coke tell us how they want us to perceive their products. These brands don't communicate about...
Electrode Inc may not have the right to dismiss a staff with such a short notice since the act carried out by Christopher is a personal issue. On the other hand, the company may have the right to dismiss him if there is a clause in the employment terms that...
Evaluating the reliability of a transportation network often involves an intensive simulation exercise to randomly generate and evaluate different possible network states. This paper proposes an algorithm to approximate the network reliability which minimizes the use of such simulation procedure. The algorithm will dissect and classify the network states into...
As the problem of full transit vehicles is encountered daily by passengers in most of the big cities, previous research evaluated the consequence of overcrowding in terms of on-board crowding and passengers not being able to board with full vehicles. The impact of overcrowding in the real world is, however,...
President Bush and I love high gas prices -- but for different reasons. When oil and gas were cheap, implementing alternative forms of energy wasn't very practical. With the cost of oil so high, that gap has started to close. Bush loves high gas prices because it...

The United States of America is becoming less united by the day. A 30-year gap now exists in the average life expectancy between Mississippi, in the Deep South, and Connecticut, in prosperous New England. Huge disparities have also opened up in income, health and education depending on where people live...
