Female participation in African labor markets: The role of information and communication technologies

This article investigates the effects of information and communication technologies (ICT) on female labor force participation in a sample of 48 African countries. We specify and estimate linear regression and dynamic panel data models with fixed effects (FE) and system-generalized method of moments (SYS-GMM) estimation over the period 2001–2017. The three main results are that ICT use (mobile phone and internet) significantly stimulates female labor force participation in Africa; this effect is enhanced by financial development and female education; the effect of ICT on female employment in Africa is strongest in the industrial sector. These results remain robust to the provision of social, cultural, and institutional variables.     

A simplified pricing model for volatility futures

We develop a general model to price VIX futures contracts. The model is adapted to test both the constant elasticity of variance (CEV) and the Cox–Ingersoll–Ross formulations, with and without jumps. Empirical tests on VIX futures prices provide out‐of‐sample estimates within 2% of the actual futures price for almost all futures maturities. We show that although jumps are present in the data, the models with jumps do not typically outperform the others; in particular, we demonstrate the important benefits of the CEV feature in pricing futures contracts. We conclude by examining errors in the model relative to the VIX characteristics. © 2010 Wiley Periodicals, Inc. Jrl Fut Mark 31:307–339, 2011     

A Profile of Poverty in Egypt

This paper presents a profile of poverty in Egypt for 1997. It assesses the magnitude of poverty and its distribution across geographic and socioeconomic groups, provides information on the characteristics of the poor, illustrates the heterogeneity amongst the poor, and helps identify empirical correlates of poverty. This poverty profile is constructed using data from the Egypt Integrated Household Survey (EIHS), which is a nationwide, multiple‐topic household survey. One of the more striking set of findings relates to the differences between the poor and the non‐poor in their educational attainments. Our results indicate a significant literacy and schooling gap between the poor and the non‐poor. On average the poor have 2.6 fewer years of schooling than the non‐poor, and their literacy rate is 27 percent lower than the non‐poor. Our results also indicate that augmenting educational attainment of the poor does not require building more schools, but reducing the poor’s opportunity cost of attending schools and increasing their returns from extra schooling, both suggesting the importance of income generating activities as a policy instrument.     

SheBelieves,but does she? Complicating white women’s understandings of the postfeminist-neoliberal empowerment discourse

Abstract

Though the academic literature focused on postfeminism, neoliberalism, and the relationship between the two is considerable, there is little exploration of these conjoined discourses as they relate to leisure culture in general, and women’s sporting lives in particular. At the level of lived experience, scholars have yet to empirically examine how women engage and are affected by the empowerment discourse punctuating many aspects of postfeminism. This study uses the U.S. Soccer Federation’s 2015 SheBelieves Campaign as an empirical site for critically examining women’s attitudes toward, and experiences of, issues of empowerment, feminism, and sexism associated with what scholars have labelled the postfeminist-neoliberal moment (McRobbie, 2009 McRobbie, A. (2009). The aftermath of feminism; gender, culture and social change. London, England: Sage. [Google Scholar]; Rottenberg, 2014 Rottenberg, C. (2014). The rise of neoliberal feminism. Cultural Studies, 28(3), 418–437. https://doi.org/10.1080/09502386.2013.857361[Taylor & Francis Online], [Web of Science ®] , [Google Scholar]). Working at the intersection of leisure studies, feminism, and physical cultural studies, this research provides a window into the complicated, and sometimes contradictory, ways women view and experience neoliberal empowerment discourses within and through sporting elements of their leisure lifestyles.     

A dimension-invariant cascade model for VIX futures

We propose a new stochastic volatility model by allowing for a cascading structure of volatility components. The model, under a minor assumption, allows us to add as many components as desired with no additional parameters, effectively defeating the curse of dimensionality often encountered in traditional models. We derive a semi-closed-form solution to the VIX futures price, and find that our six-factor model with only six parameters can closely fit spot VIX and VIX futures prices from 2004 to 2015 and produce out-of-sample pricing errors of magnitudes similar to those of in-sample errors.     

Is emigration of workers contributing to better schooling outcomes in Nepal?

This paper presents evidence on how emigration for work affects schooling outcomes for primary and secondary school‐age children in Nepal. Using an instrumental variable strategy exploiting past migration network, we show that the identified effects critically depend on how schooling outcomes are measured. While conventional measures of school attendance indicate no impact, our new set of schooling status and schooling gap measures reveals significant impacts. Schooling status measures reveal favorable impacts for girls, and for emigration to India. Schooling gap measures reveal favorable effects of all emigration on schooling outcomes for girls and of emigration to other countries for boys.     

Team Formation and Self-serving Biases

There is extensive evidence which indicates that people learn positively about themselves. We build on this finding to develop a model of team formation. We show that under complete information learning positively about oneself prevents efficient team formation. Agents becoming overconfident tend to ask for an excessive share of the group outcome. Positive learning generates divergence in workers' beliefs and hampers efficient team formation. Interestingly, in a context of incomplete information regarding the partner's ability, extensive learning biases may reduce the divergence in agents' beliefs and facilitate efficient team formation as a result. We apply our model to coauthorship and organizational issues.     

QUANTIFYING ABSOLUTE POVERTY IN THE DEVELOPING WORLD

We estimate that in 1985 about one in five persons in the developing world lived in poverty, judged by the standards of the poorest countries. This rises to one in three at a common, more generous, poverty line. The aggregate consumption short-fall of the poorest fifth is about one half of one percent of world consumption, while that of the poorest third is a further one percent. The shape of the distribution of consumption suggests that aggregate poverty would fall fairly rapidly if moderate growth in average consumption levels can be sustained, and the poor share at least proportionally in that growth. However, it would take only small adverse shifts in the world distribution of consumption to eliminate the gains to the poor from growth.     

Forecasting aggregate consumers' expenditure in the UK using the DHSY model

The performance of the DHSY model in predicting the growth of aggregate consumers' expenditure in the UK over the period 1985–1988 is examined. The model is applied to four different combinations of consumption variable and data type. Results show, in all cases, the predictive performance of the DHSY model to be poor. However, applied to seasonally adjusted data, an improvement can be achieved by allowing for systematic variation in coefficients. In particular, a variable-coefficient DHSY model displays no tendency to underpredict the growth of total consumers' expenditure and accurately captures the volatility of non-durable expenditure.
