Gold and the US dollar: Hedge or haven? 总被引:1,自引:0,他引:1
Mark Joy 《Finance Research Letters》2011,8(3):120-131
Using a model of dynamic conditional correlations covering 23 years of weekly data for 16 major dollar-paired exchange rates, this paper addresses a practical investment question: Does gold act as a hedge against the US dollar, as a safe haven, or neither? Key findings are as follows. (i) During the past 23 years gold has behaved as a hedge against the US dollar. (ii) Gold has been a poor safe haven. (iii) In recent years gold has acted, increasingly, as an effective hedge against currency risk associated with the US dollar. 相似文献

This study investigates the internal migration of black males in South Africa over the period after the formal end of Apartheid using the 1996 census data. The two issues of our primary interests are the following: (i) whether migration patterns of black individuals are consistent with the income‐maximising hypothesis as related to the destination choice; and (ii) whether the redistribution of human capital is detected in internal migration. The results from conditional logit regressions on choices among individuals in 318 districts show that individuals prefer districts with higher expected wages, conditional on other regional characteristics. In addition, there exist differing preferences on the share of population with post‐secondary education by individuals with commensurate educational attainments. Black individuals with post‐secondary education tend to migrate into areas with a higher share of population with post‐secondary education and vice versa, which confirms the divergence of human capital levels across districts. 相似文献

Empirical literature on foreign investors' trading in stock markets heavily relies on US Treasury International Capital (TIC) data. Biases in TIC data and the fact that it represents only one source country raise questions on how reliable the conclusions based on TIC data are. Employing novel data of complete foreign flows compiled at destination, we answer these questions. Although the correlations between net flows derived from TIC and destination‐compiled data are low, and visible differences exist in some individual country results, TIC findings are not far off in central tendency. Notably, however, net foreign flows' persistence, positive response to world returns and positive contemporaneous correlation with local returns are more significant than TIC data suggest. Measurement noise in TIC data appears to result in underestimation of these key features. 相似文献

This article contributes to the debate on the role of land in reducing poverty in rural South Africa. It uses the year of arrival in the former homelands as an instrument for land access and size. This identification strategy is based on the fact that African households were forcibly relocated to the homelands during the apartheid. Due to increasing population pressure, later arrivals were less likely to be assigned land. The results show that land has a large positive effect on household welfare. Because the homelands are relatively disadvantaged areas, these results provide a lower bound for the positive effects of land on household welfare. 相似文献

We examine natural disasters and long‐run climatic factors as potential determinants of international migration, implementing a panel dataset of bilateral migration flows from 1960 to 2000. We find no direct effect of long‐run climatic factors on international migration across our entire sample. These results are robust when conditioning on origin‐country characteristics, when considering migrants returning home, and when accounting for the potential endogeneity of migrant networks. Rather, we find evidence of indirect effects of environmental factors operating through wages. We find that epidemics and miscellaneous incidents spur international migration, and there is strong evidence that natural disasters beget greater flows of migrants to urban environs. 相似文献

We analyze the statistical properties of three price discovery measures: The variance ratio, the weighted price contribution (WPC), and the R2 of unbiasedness regressions. We find that, if the price process is a driftless martingale, only the WPC is an unbiased estimator for the return variance explained during a time interval. For autocorrelated processes with a drift, only the R2 of the unbiasedness regression is consistent, but it is biased for small samples. 相似文献

There has been a considerable amount of work focusing on job satisfaction and sex, generally finding that women are more satisfied than men despite having objectively worse job conditions. But there is little evidence on whether job satisfaction differs by race or ethnicity. We use data from the 2010 National Survey of College Graduates to examine the relation between job satisfaction and race and ethnicity among Asian, black, Hispanic/Latino, and white workers. Overall job satisfaction does not differ by sex among college graduates. Relative to white workers of the same sex, Asian and black workers are far less satisfied. The lower satisfaction of Asian and black workers relative to white workers is not explained by immigrant status, job match, or other individual or job characteristics. 相似文献

Our paper presents an empirical analysis of entrepreneurial well-being using a large-scale longitudinal household survey from the UK that tracks almost 50,000 individuals across seven waves over the period 2009–2017, as well as a number of exploratory case studies. We contribute to the existing literature by investigating how entrepreneurial well-being varies across locations along the urban-rural continuum, and across wealthy-deprived neighbourhoods. We use a Coarsened Exact Matching (CEM) approach to compare the well-being outcomes of individuals who switch into self-employment from waged employment, and show that entrepreneurial well-being, in the form of job satisfaction, is significantly higher for those living in semi-urban locations, relative to those living in urban and rural locations. We argue that semi-urban locations provide an optimal combination of ease of doing business and quality of life. Our results also show that individuals in wealthy neighbourhoods who switch into self-employment experience higher job satisfaction than otherwise comparable individuals living in materially deprived neighbourhoods, although the latter experience greater levels of life satisfaction following the switch. 相似文献
