Economic Union,Finance and Growth: A Prognosis in West Africa

This paper compares the impact of financial development on economic growth in the Union Économique et Monetaire Ouest Africaine (UEMOA) and non‐UEMOA countries. It also examines the finance‐growth nexus before and after the formation of UEMOA, as well as the indirect effect of economic union on economic growth through the financial sector. The study reveals a significant difference in the finance‐growth nexus between UEMOA and non‐UEMOA countries. Specifically, financial development has a robust positive impact on growth in UEMOA countries, while the impact is tenuous in non‐UEMOA countries. However, we find no remarkable difference in the finance‐growth nexus before and after the formation of UEMOA. We also reveal that economic union has no robust indirect effect on economic growth via the financial sector. The economic implication is that UEMOA could have economic benefits, but financial development is not a channel through which it influences growth. Therefore, it is necessary to reposition the union so that it can enhance the impact of finance on growth.     

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.     

How does investor relations disclosure affect analysts' forecasts?

We study the relationship between investor relations disclosure and analyst forecast properties in Australian firms, a setting dominated by small firms with limited analyst coverage and requiring continuous disclosure of price sensitive information. We find increasing disclosure in the time period investigated is associated with greater accuracy in firms disclosing fewer items. Disclosure was unrelated to forecast dispersion, possibly due to the low analyst following. In periods of uncertainty, the investor relations awards effectively discriminated quality from quantity of disclosure. These findings highlight the importance of active communication with analysts, particularly in firms providing less disclosure and during periods of uncertainty.     

Sustainability Analysis of Ecotourism on Yao Noi Island,Thailand

International visitor arrivals from Malaysia's 10 major source markets are examined using Lagrange Multiplier (LM) unit root tests with one and two structural breaks to ascertain whether shocks to the time path of tourist arrivals are permanent or transitory. The LM unit root test with one break is able to reject the unit root null for between 60% of source markets where the break is specified as in the intercept and 90% of source markets where the break is specified as in the intercept and slope. The LM unit root test with two breaks is able to reject the unit root null for all source markets, irrespective of how the break is specified. This result suggests that the effects of shocks on the growth path of tourist arrivals to Malaysia from its major markets are only transitory and that Malaysia's tourist sector is sustainable in the long run. Although the effects of shocks are not permanent, we do find that following shocks the growth in tourist arrivals from Malaysia's source markets has generally slowed. This result suggests there is a need to reduce the negative effects of slower growth in the recovery phase.     

Do Malaysian house prices follow a random walk? Evidence from univariate and panel LM unit root tests with one and two structural breaks

In this article we apply univariate and panel Lagrange Multiplier (LM) unit root tests with one and twostructural breaks proposed by Lee and Strazicich (2003, 2004) and Im et al. (2005) to examine housing prices for five different housing price indices (all housing, detached housing, semi-detached housing, terrace housing and high-rise housing) in 14 states of Malaysia to test whether housing prices exhibit a random walk. Our main finding from the univariate LM unit root tests is that for the vast majority of states housing prices follow a stationary process about a segmented trend. The results of the panel LM unit root tests provide overwhelming evidence that house prices are segmented trend reverting.     

Conditional convergence in US disaggregated petroleum consumption at the sector level

We test for convergence in disaggregated petroleum consumption at the sector level for the United States using the recently proposed GARCH unit root test, suitable for high frequency data. We find evidence of convergence for just over half of the series, including total petroleum consumption in each sector and approximately three quarters of the disaggregated petroleum consumption series in transportation.     

Network patterns and competitive advantage before the emergence of a dominant design

This study examines the performance implications of the alliance networks of 49 firms that competed for two technology standards in the U.S. local area network industry from 1989 to 1996. During the race to define a dominant design, individual firms attract the suppliers of complements by building alliance networks to favor the firms' preferred technology standard. Controlling for the number of suppliers in each technology standard community and the extent of technical progress achieved by individual firms, the panel data analysis shows that central firms with high ego network density, coupled with a strategic intent to acquire and share knowledge broadly within the technological community, achieve better innovation performance. The size of the technological community and some random events in the early formation of the industry do not provide a sufficient explanation of how these firms gain the diverse support of suppliers or enhance their competitive advantage. By demonstrating the independent and contingent effects of alliance network properties, this study explains how network patterns might enhance or limit the benefits of alliance networks when focal firms embrace different innovation strategies.

Is the tourism‐led growth hypothesis stable for Malaysia? A note

This letter extends the Gunduz and Hatemi‐J study on the tourism‐led growth hypothesis with the Malaysian data. The rolling subsample causality test was employed to demonstrate the validity and stability of the tourism–growth causality relationship. Our result shows the causality relationship is valid and stable over the sample period. Copyright © 2009 John Wiley & Sons, Ltd.     

The moderation effect of workplace experience on innovation motivation: a study of STEM faculty in Singapore

While the topic on drivers of innovation has been intensely studied, most of the literature tends to examine motivators at a point in time with the assumption that they are stable. However, shifts in social and environmental contexts may change motivators of behaviour. In light of the discrepancy, this study uses the person–environment fit theory and examines innovation-stimulating work climate from the perspective of workplace experience. With a sample of 276 faculty members in two major universities in Singapore, we test the moderating effect of workplace experience on three motivators – peer influence, performance evaluation and resource access, and found that with increased workplace experience, the effectiveness of these environmental motivators diminished. Resource access and co-worker influence become less salient with the exception of evaluation, which remains important. The implications for university administration and academic training programs are discussed.
