a b s t r a c tIt is commonly believed that being listed on the World Heritage List (WHL) results in attracting more tourists. However, this assumption has not been generally subject to rigorous econometric approach in the existing literature. To fill this gap, we assess the impact of the accreditation World Heritage status on the "Historic Centre of Macau" in 2005 on visitor numbers to the territory to identify the real effect of WHL on fostering tourism. In doing so, because of the policy restrictions on the mainland Chinese tourists, such tourists have been excluded from the analysis. The empirical results indicate that there is no significant effect of WHL on promoting tourism other than possibly a short-run tourism-enhancing impact. Notably, this effect is particularly relevant to Asian tourists. This paper discusses these results in the wider context of econometric analyses of tourism.

This paper investigates the effect of tax incentives on R&D activities in Taiwanese manufacturing firms. Specifically, we assess the potential R&D-enhancing effect on recipients of R&D tax credits compared with their non-recipient counterparts. Moreover, the potential difference in the R&D-enhancing effect between high-tech and non-high-tech firms is also examined. Utilizing a firm-level panel dataset during 2001 and 2005, empirical results obtained by propensity score matching show that recipients of R&D tax credits appear on average to have 93.53% higher R&D expenditures and a 14.47% higher growth rate for R&D expenditures than non-recipients with similar characteristics. The R&D-enhancing effect of R&D tax credits is not found to be particularly relevant to high-tech or non-high-tech firms. We further employ a generalized method of moment (GMM) of the panel fixed model to control for the endogeneity of R&D tax credits and firm heterogeneity in determining R&D expenditure. Various estimates based on the entire sample and high-tech-firms are quite similar and there is a significantly R&D-enhancing effect of R&D tax credits. This result suggests that the R&D preferential policy has induced more R&D expenditure by firms in Taiwan. While the existence of the R&D-enhancing effect brought on by tax incentives is intuitive, the estimates can provide insightful implications for the R&D tax policy.
