If Time Is Money Is It a Common Currency? Time in Anglo,Asian, and Latin Cultures

ABSTRACT

Social time affects the timing and frequency of purchases, the hours consumers patronize businesses, and how long consumers expect products to last. Understanding how culturally based social time attitudes differ will help marketers tailor their offerings and messages to consumers whose concepts of time differ. This exploratory study combined related streams of time literature to examine constructs of social time differences across cultures. Drawing upon a sample of 1377 respondents from six countries representing three cultural groups (Anglo, Latin, and Asian), the study explores the similarity and differences of cultural social time differences among these three groups.     

TECHNICAL NOTE A MODIFIED EOQ MODEL WITH TEMPORARY SALE PRICE DERIVED WITHOUT DERIVATIVES

Most previous works applied differential calculus to derive optimal solutions for economic ordering policy. The formulations are suggested in this short note to show that optimal solutions can be derived algebraically without using differential calculus to treat the EOQ model with a temporary sale price.     

Implementation of Four Models for Outstanding Liabilities in Winbugs: A Discussion of a Paper by Ntzoufras and Dellaportas

Abstract

Ntzoufras and Dellaportas (2002) described four models for outstanding claim amounts of the “reported but not settled” variety. Two of the models incorporated claim-counts data in addition to the claim amounts themselves in order to add a hierarchical stage in the usual log-normal and state-space models. The purpose of this discussion is to describe how the models presented in Ntzoufras and Dellaportas may be implemented using WinBUGS. The use of WinBUGS to implement the Bayesian analysis of a number of other actuarial models was considered by Scollnik (2001).     

Labour disputes,investment decisions and the judiciary

In this article, we show that the presence of the judiciary in the background of labour relationships is not neutral within these relations: its potential intervention in case of an ex-post layoff and conflict over the severance payment can promote ex-ante efficient specific investment decisions. This ability to promote efficiency depends on the judiciary's aptitude to balance out the parties' ex-post bargaining powers. Interestingly one of the results shows that, if workers' bargaining power in wage negotiations is low, which implies that they expect low returns from continuing the relationships, an increase in the exogenous layoff probability should lead judges to be less lenient towards them.     

Open interest,volume, and volatility: evidence from Taiwan futures markets

This paper examines the relationships amongst volatility, total trading volume (TVOL) and total open interest (TOI) for three Taiwan stock index futures markets as well as the role of the latter two variables in the dynamics of GARCH modeling and forecasting. From both ex-post and ex-ante perspectives, we study this issue by using the VAR model and augmented GARCH-type models, respectively. For the GARCH-type models, we employ both symmetric and asymmetric models augmented with lagged logs in TOI and/or TVOL. We find that whether addition of these two variables helps the basic GARCH models predict future volatility depends upon the sample period examined for all three sets of futures. Nonetheless, the best three models for out-of-sample volatility forecasting in the MSE sense are generally the augmented models for all sub-intervals and all three futures contracts.     

Managing sourcing team effectiveness: The need for a team perspective in purchasing organizations

To meet today’s high demands on the purchasing function, sourcing teams have become the standard in contemporary corporate purchasing organizations. Sourcing teams are often started with high expectations. However, after making a promising start many of these teams appear to be unable to operate effectively and to meet management expectations. This study shows that sourcing team effectiveness is particularly hindered by a lack of team perspective in many purchasing organizations. In this paper, the results of a large-scale, cross-sectional survey to address the success factors for sourcing teams are discussed. We aim to clarify the factors behind sourcing team performance, taking into account the specific task and organizational context. It is concluded that purchasing executives should shift their focus towards employee involvement and team processes, to enable teams to actually meet and even surpass the expectations placed on them.     

Context sensitive multimodal road planning: a case study in Cape Town, South Africa

Road planning practice relies almost exclusively on parameters related to traffic factors, such as private vehicle speeds and volumes. In many developing countries the requirements for public transport and non-motorised transport are not explicitly integrated into the planning process, despite the fact that these form the primary mode of transport for the majority of the population. This affects the mobility opportunities for these sectors of the population and contributes to poor road safety, especially with regards to pedestrians. The research outlined in the paper posits that, in order to assess the usage and needs of the road holistically, other factors related to the adjacent land uses, socio-economic characteristics of the population the road serves, and the environmental context within which the road is located, factors heavily in how the road is used and should, therefore, be considered within the planning process. The paper describes a methodology to include these factors in the planning of roads. The method attempts to prioritise amongst the five primary road based modes (public transport, car, freight, walking and cycling) based upon a combination of traffic and non-traffic factors. The method employed uses a geographic information system (GIS) based spatial multiple criteria evaluation (SMCE) model with inputs from widely available data sources such as census, household travel surveys, land use and environmental data to arrive at solutions for modal priorities. A case study is conducted along an arterial route in Cape Town, South Africa, providing infrastructure planning recommendations and audit possibilities for the future. Since weighting is an important driver in the SMCE process, a sensitivity analysis is conducted to investigate the effect of alternative weighting schemes on the outputs from the method.     

International Trade and Accounting Policy Choice: Theory and Canadian Evidence

The accounting policy choice literature has identified many factors which have been shown to be useful in explaining cross-sectional variation in the accounting methods used by public companies. One relationship which has been relatively unexplored in this literature is the potential effect of international trade on accounting choice. This study proposes that international trading activities may create incentives for firms to choose income increasing accounting policies. This proposition was tested by examining the depreciation choices of a sample of Canadian firms. Results suggest that importers were more likely to choose income increasing accounting methods than non-importers, while exporting was not found to be related to this accounting choice. These diverging results may be caused by the declining value of the Canadian dollar (relative to the US dollar), which tends to benefit exporters, but is of detriment to importers.
