Comparing theories to explain e-commerce adoption

E-commerce is a strategy for rapid growth, especially by small and medium sized businesses (SMEs). However, the adoption rate of e-commerce by SMEs in Latin America is still undersized. The authors compare the theory of planned behavior (TPB) and the theory of reasoned action (TRA) using structural equation modeling to determine which is better at predicting e-commerce adoption intentions among 210 SME managers/owners in Chile. Contrary to previous research with American respondents, the study does not find significant differences between the two theories. Thus, academics should select the more parsimonious model (TRA) to study e-commerce adoption issues in developing countries.     

An analysis of trading strategies in eleven European stock markets

Abstract

In recent years, the validity of the weak form efficient market hypothesis (EMH) has been called into question as several studies have uncovered evidence that technical trading rules have predictive ability with respect to both developed and emerging stock market indices. This study analyses the forecasting power of 2 of the most popular trading rules using index data for a selection of 11 European stock markets over the January 1991 to December 2000 period. The findings indicate that the emerging markets included in this paper are informationally inefficient; these markets displayed some degree of predictability in their share returns, although the developed markets did not. Furthermore, the results point to large differences in the performance of the rules examined; while small size filters consistently outperformed the buy-and-hold strategy in the emerging markets examined even after the consideration of transaction costs, the performance of the moving average rules was erratic and varied dramatically from market to market.     

An Intelligent Distributed System for Strategic Decision Making

The decision-making process in strategic planning is often too complex to be handled by conventional methods. Strategic planning problems (building new plans, new product planning, etc.) belong to the class of problems called ill-structured by H. Simon. They involve a decomposition of the main problem into a set of subproblems, a reasoning process at the subproblem level, and then a coordinated and aggregated process to build a global solution. Because partial solutions are generated without having a complete view of the global objective, this type of decision-making process very often generates incoherent and contradictory hypotheses and actions. Therefore, the main problem is to find a way to achieve coherence and coordination among decisions made locally by different agents, at different levels.Recent advances in Artificial Intelligence, particularly in the field of multi-agent theory, offer great promises in modeling strategic planning processes. In this article we present a general framework called 'A Coherent Plan of Coordinated Actions (CPCA)' for building intelligent distributed strategic decision making systems which integrates advances in both distributed decision making and Distributed Artificial Intelligence. We then describe a multi-blackboard system, ARISTOTE, which is aimed at helping corporate managers address the feasibility and coherence of a plan of actions.     

A GPS data-based analysis of built environment influences on bicyclist route preferences

This study examines the effects of built environment features, including factors of land use and road network, on bicyclists' route preferences using the data from the city of Seattle. The bicycle routes are identified using a GPS dataset collected from a smartphone application named “CycleTracks.” The route choice set is generated using the labeling route approach, and the cost functions of route alternatives are based on principal component analyses. Then, two mixed logit models, focusing on random parameters and alternative-specific coefficients, respectively, are estimated to examine bicyclists' route choice. The major findings of this study are as follows: (1) the bicycle route choice involves the joint consideration of convenience, safety, and leisure; (2) most bicyclists prefer to cycle on shorter, flat, and well-planned bicycle facilities with slow road traffic; (3) some bicyclists prefer routes surrounded by mixed land use; (4) some bicyclists favor routes which are planted with street trees or installed with street lights; and (5) some bicyclists prefer routes along with city features. This analysis provides valuable insights into how well-planned land use and road network can facilitate efficient, safe, and enjoyable bicycling.     

Detecting jumps from Lévy jump diffusion processes

Recent asset-pricing models incorporate jump risk through Lévy processes in addition to diffusive risk. This paper studies how to detect stochastic arrivals of small and big Lévy jumps with new nonparametric tests. The tests allow for robust analysis of their separate characteristics and facilitate better estimation of return dynamics. Empirical evidence of both small and big jumps based on these tests suggests that models for individual equities and overall market indices require incorporating Lévy-type jumps. The evidence of small jumps also helps explain why jumps in the market index are uncorrelated with jumps in its component equities.     

Health Belief Model: Evaluating Marketing Promotion in a Public Vaccination Program

National health objectives are driven to increase participation rates. Individual health decisions are determined by attitudes, behavior, lifestyles, and government policies. This research, therefore, examined not just the development and delivery of a message targeting individual voluntary behavior change, but the intention of changes in social structures that will facilitate individuals reaching their potential; thus the purpose of this article is to shed light on the uptake of the human papillomavirus (HPV) immunization using the health belief model (HBM). Research was conducted with the use of focus groups by drawing on the framework of the HBM. This research approach is conceptual by nature, based on the virtue of marketing promotion and on HBM literature. Though offering the vaccine free to the general public provides additional evidence to certain groups on the intention to act or uptake of the vaccine, awareness levels were found to be poor despite increased efforts by the government trying to promote this vaccine. There was evidence that social capital and trust can produce effective communication message strategies that reinforce social bonds. This article provides an interesting basis for further investigation; however, as implausible as it seems the article also contributes to the concept of perceived benefits and of self-efficacy.     

A Sword and a Shield: South Korea's Strategic Use of World Trade Organization Litigation

The World Trade Organization (WTO) has since its inception in 1995 produced a cohort of 108 “fully litigated” trade cases. Quantitative and qualitative analysis of this cohort of cases reveal that South Korea ranks first among all Asia Pacific nations in appearances as complainant. Similarly, Korea ranks first among the 13 most litigious WTO members in the relative frequency with which it converts WTO Consultation Requests to formal litigation. Furthermore, its litigation history reflects a strategy to employ the formal WTO litigation venue in the service of two key exports: steel and semiconductors. Through this strategy, Korea has challenged U.S. safeguard measures on steel and defended its own putative subsidization of semiconductor manufacturers from countervailing duties imposed by the United States, European Union, and Japan.     

micro-Business Community Responsibility in Australia: Approaches, Motivations and Barriers

Micro and small businesses contribute the majority of business activity in the most developed economies. They are typically embedded in local communities and therefore well placed to influence community wellbeing. While there has been considerable theoretical and empirical analysis of corporate citizenship and corporate social responsibility (CSR), the nature of micro-business community responsibility (mBCR) remains relatively under-explored. This article presents findings from an exploratory study of mBCR that examined the approaches, motivations and barriers of this phenomenon. Analysis of data from 36 semi-structured interviews with micro-business owner-operators in the Australian city of Brisbane revealed three mBCR approaches, suggesting an observable mBCR typology. Each mBCR type was at least partly driven by enlightened self-interest (ESI). In addition to a pure ESI approach, findings revealed ESI combined with philanthropic approaches and ESI combined with social entrepreneurial approaches. The combination of doing business and doing good found amongst participants in this study suggests that many micro-business owner-operators are supporters of their local communities and, therefore, driven by more than profit. This study provides a fine-grained understanding of micro-business involvement in community wellbeing through a lens of responsible business behaviour.     

Collegial Entrepreneurialism

Abstract

In recent decades, Australian universities have corporatized. Encouraged by government policies, universities adopted modernization practices that have been widely questioned. ‘Collegial entrepreneurialism’ is an approach that builds on collegial processes to protect academic values from the excesses of modernization. This paper examines the perceptions of business academics about the impacts of modernization in autonomous graduate schools of business. The research was undertaken prior to the most recent wave of higher education reform under which most of these schools disappeared. Their experience of three consequences of modernization, ‘hard’ managerialism, academic consumerism and fragmentation of work, provides insight into whether collegiality and academic values can exist within an entrepreneurial academic unit. Results indicate that overt manifestations of modernization are not threatening to ‘collegial entrepreneurialism’. However, in the absence of academic leadership, the more covert influences of consumerism and fragmentation pose a threat to the survival of ‘collegial entrepreneurialism’.     

Getting from “just-in-case” to “just-in-time”: Insights from a simple model

Many factory managers are hesitant about implementing a just-in-time system due to concern about the dip in productivity that occurs. Here, a simple analytic model is used to study the trade-off between disruption and learning/improvement on a production line. While simple, the model is shown to capture many of the effects of just-in-time mentioned in the literature.Using insights from the model, an attempt is made to identify those factors to which successful implementation of just-in-time is most sensitive.
