Greenlandic glaciers distinct from the ice sheet make up 12% of the global glacierized area and store about 10% of the global glacier ice volume (Farinotti et al., 2019). However, knowledge about recent climate change-induced volume changes of these 19,000 individual glaciers is limited. The small number of available glaciological and geodetic mass-balance observations have a limited spatial coverage, and the representativeness of these measurements for the region is largely unknown, factors which make a regional assessment of mass balance challenging. Here we use two recently released digital elevation models (DEMs) to assess glacier-wide elevation changes of 1,526 glaciers covering 3,785 km2 in west-central Greenland: The historical AeroDEM representing the surface in 1985 and a TanDEM-X composite representing 2010–2014. The results show that on average glacier surfaces lowered by about 14.0 ± 4.6 m from 1985 until 2012 or 0.5 ± 0.2 m yr−1, which is equivalent to a sample mass loss of ~45.1 ± 14.9 Gt in total or 1.7 ± 0.6 Gt yr−1. Challenges arise from the nature of the DEMs, such as large areas of data voids, fuzzy acquisition dates, and potential radar penetration. We compared several different interpolation methods to assess the best method to fill data voids and constrain unknown survey dates and the associated uncertainties with each method. The potential radar penetration is considered negligible for this assessment in view of the overall glacier changes, the length of the observation period, and the overall uncertainties. A comparison with earlier studies indicates that for glacier change assessments based on ICESat, data selection and averaging methodology strongly influences the results from these spatially limited measurements. This study promotes improved assessments of the contribution of glaciers to sea-level rise and encourages to extend geodetic glacier mass balances to all glaciers on Greenland.

This paper explores the relationship between natural resource revenues and expenditure decentralization. While the literature suggests that an abundance of natural resources may have deleterious effects on fiscal decentralization and other variables, existing empirical evidence regarding expenditure decentral- ization is scant and suspect. We find that expenditure decentralization is highly persistent. We take this persistence into account and use four different estimation strategies to examine whether natural resource revenues influence expenditure decentralization. Increases in natural resource rents as a percentage of Gross Domestic Product (GDP) statistically significantly and negatively affect expenditure decentralization. A 1% year-on-year increase in natural resource rents reduces estimated expenditure decentralization by approximately 0.1% to 0.3%. This result is robust to an alternative measure of resource dependence. Our findings strongly suggest that increases in resource endowments lead to a centralization of government expenditures.

This article examines the impact of trade openness on wage inequality in Malaysia during the period 1984–1997. Malaysia has operated a very open trade regime since the 1960s and has pursued aggressive import substitution and export supporting policies. This development strategy is very different to that adopted in many other emerging economies where trade liberalisation has been associated with greater wage inequality. The aim of the present study is to examine whether Malaysia's more open approach to international trade has had a similar effect on wage inequality. The results suggest, in fact, that this is not the case.

The aim of this paper is to present a picture of return to education in Malaysia over the period from 1984 to 1997 based on earning equations model. The paper employed a set of data comprising micro-level data from the Household Income Survey (HIS) for several years during the period 1984 to 1997. The main finding of this paper is the changes in the wage differentials favouring the middle level of education (secondary level of education) workers. In general, the results show that the return for each level of qualification declined between 1984 and 1997,especially at the higher levels (diploma and degree). Interestingly, the return to education for females at low levels of education is higher than the return by males. However, at higher levels of qualification, especially for those with secondary and high school qualifications, males traditionally have a higher return compared to females workers. The results also indicated a significant gender differential, however the differences has fallen over time.
