Does tourism-led growth hypothesis exist in Mauritius? Evidence from disaggregated tourism markets

We use the data of total tourism market and 10 major tourism markets in Mauritius to test the validity of tourism-led growth hypothesis in the country for the period 1980–2011. Using causality techniques, we confirm the hypothesis for the total tourism market. However, tourism-led growth exists in only 6 of the 10 markets. We conclude that not all tourism markets are contributing substantially to Mauritius’ economy.

Testing for weak-form efficiency of crude palm oil spot and future markets: new evidence from a GARCH unit root test with multiple structural breaks

There is a sizeable literature that tests for weak-form efficiency in commodity and energy spot and future prices. While many studies now allow for multiple structural breaks to address the criticism that conventional unit root tests have low power to reject the unit root null in the presence of structural change, the extant literature overlooks the fact that conventional unit root tests are biased in the presence of conditional heteroscedasticity. We apply a recently developed generalized autoregressive conditional heteroscedasticity (GARCH) unit root test with multiple structural breaks to crude palm oil spot and future prices and find much more evidence against weak-form efficiency than that found using tests that fail to allow for conditional heteroscedasticity. Our results point to the importance of allowing for heteroscedasticity when testing for efficiency in commodity and energy spot and future prices.     

Empirical tests of real estate market efficiency

Recent empirical research using real estate data has supported the weak and semi-strong forms of the efficient markets hypothesis. Previous studies have not included an estimate of expected appreciation into the tests of market efficiency, thus raising a question about the reliability of the results. We first use a market model to test for market efficiency with results similar to those reported by others. We next use a dynamic multiple indicator, multiple cause (DYMIMIC) model, which extracts a vector of expected appreciation from the price data, to test market efficiency. This approach produces superior results and a stronger conclusion about the efficiency of housing markets. The results indicate limited adjustment delays which can be explained by the existence of high transactions and search costs.     

Advertising, Its Determinants, and Market Structure

This study derives a formal model of firm advertising behavior and applies it to the industry level to figure out the relationship between advertising and market structure. The firm advertising model shows that both consumer preference andfirm-specific advertising competence jointly determineprofit-maximizing advertising intensity. At the industry level, advertising intensity is represented multiplicatively by consumer preference and a measure of market structure, which reflects the joint distribution of the levels of advertising competence and market shares among firms. The new market structure measure suggests that those single-dimensional measures of market structure such as seller concentration and the Herfindahl index are inadequate in explaining interindustry differences in advertising intensity, and that the long-debated advertising-concentration relationship differs depending primarily on the appropriability of advertising. An empirical analysis of 426 five-digit Korean manufacturing industries shows that an inverted U-shaped relationship between the Herfindahl index and industry advertising intensity is observed for consumer goods industries but a lazy J-shaped relationship for producer goods industries.     

价值运筹——价值工程在世※界经济新运行形态下的发展

认知世界经济的巨大变化需要新的观念,人类经济总体发展模型又称“四方式二形态”假说,可以作为研究经济和管理问题的基本框架和准则。由此得出当前世界经济按功能经济形态运行。列出了一些与物质经济运行形态不同的主要的新特征。总结出六条关于功能价值的基本原理,以供处理有关问题之用。给出了“价值运筹”的定义,指出价值运筹的实质是“智能经营”,因此“全员价值运筹”是必然的选择。它将推动企业管理创新     

论"经济人"假设的发展

对新古典经济学"经济人"假设的批判体现在三个方面:对"经济人"完全理性的修正;对个人利益与社会利益一致性的批判;对"经济人"利益目标函数的修正。在市场经济条件下,为了体现"经济人"利益目标要求,应建立按要素分配的分配制度和"经济人"自由支配要素收入的产权制度;为了约束"经济人"的行为,应把"依法治国"与"以德治国"紧密结合起来。

The Logical Framework Approach–Millennium

The Logical Framework Approach (LFA) has proved to be a valuable tool for project approval, design, and evaluation. However, a few pitfalls make it hard to use within today's project management framework and to integrate with other project management tools. This article proposes an updated version of the LFA to improve its compatibility with today's corporate culture, project management framework, and tools. We propose to call the updated tool the Logical Framework Approach–Millennium (LFA‐M). The LFA‐M is a seven‐step approach leading to the development of the Logframe‐Millennium (LF‐M), a five‐column and four‐line matrix describing major project commitments and providing an overall understanding of the project. It was successfully implemented at the Canadian Space Agency and the Canadian Nuclear Safety Commission. The LFA‐M fits well within today's project management framework and corporate culture and leads easily to other project management tools.
