Analysis of School Enrollment in Ghana: A Sequential Approach

In this paper, we depart from the standard way of analyzing school enrollment by accounting explicitly for educational selectivity in order to examine the determinants of child school enrollment in Ghana. Using data from the Ghana Living Standard Survey round 6 (GLSS 6), we estimate a three‐step sequential logit model for the determinants of secondary school enrollment and its dependence on completing primary school. We find that family resources such as parental education, household income and the gender of the head of the household play a role in households' child schooling decisions. Educated parents are relatively more likely to enroll their children in primary school and keep them in school until they complete primary education. As well, we show that educated parents do not promote a gender‐biased investment in the schooling of children at the primary level. While household welfare does not influence children's entry into primary school importantly, their completion of primary school depends on household welfare. The study sheds more light on the pro‐male bias phenomenon regarding entry into primary school and primary school completion. Policies to promote the achievement of Sustainable Development Goal 4 in Ghana must be grade sensitive.     

The Impact of Single Stock Futures on Market Efficiency and Volatility: A Dynamic CAPM Approach

The concerns regarding regulations of futures markets and their destabilizing ability are unresolved in both developed and developing markets. Following stringent regulations of single stock futures (SSFs) for resumption episode after financial crises, this study addresses this concern and investigates the destabilizing impact of SSFs on the underlying stocks in an emerging economy using data of companies listed in the Karachi Stock Exchange between 1999 and 2008. Specifically, the study explores whether SSFs have caused a simultaneous increase in the volatility and operational efficiency of their underlying spot market counterparts. The results reported in the study show that the introduction of SSFs has no significant impact on market efficiency and volatility of SSFs underlying stocks and non-SSFs stocks. The results affirm that SSFs have, at least, no destabilizing impact on the underlying stocks.     

Market response of US equities to domestic natural disasters: industry-based evidence

This study investigates US industry-based price response to domestic natural disasters over the period 1960–2015. Using an event study methodology, we estimate pre-, during and post-disaster impacts. We document a slower response in the pre-disaster period than in the post-disaster period. We further find that industries react differently to the same disaster and that reactions are not always negative. For example, meteorological disasters have a positive (negative) market impact on Gold (Banking). Moreover, we provide evidence that not every industry responds similarly to different disasters, e.g., Gold reacts positively (negatively) to meteorological (geophysical) disasters.

Measuring volatility persistence in the presence of sudden changes in the variance of Canadian stock returns

Abstract.  It is well known that volatility persistence is overestimated if regime shifts are not accounted for in the standard GARCH model. This research detects time periods of sudden changes in variance using the iterated cumulated sums of squares (ICSS) algorithm. Using weekly data for the Canadian stock market indicates that after accounting for endogenously determined volatility shifts in the GARCH model, the estimated persistence in volatility is significantly reduced. This casts some doubt on previous findings that volatility in financial markets is highly persistent. The findings have important implications for investors and financial market participants.

The growth and management of R&D outsourcing: evidence from UK pharmaceuticals

Outsourcing of research and development (R&D) activities has become a major management issue for R&D and technical managers within firms. It has also been of growing concern to academics who are trying to chart the implications of the increasingly distributed nature of research and innovative activities in advanced economies. This study is based on a survey of research-based pharmaceutical companies operating in the United Kingdom conducted in 2004–2006. The aim of this paper is to outline the main reasons for pharmaceutical firms to outsource R&D and the management practices followed by such companies in relation to outsourcing. The research results provide interesting findings in relation to, for example, the reasons behind outsourcing, the decision-making processes behind such practices and barriers to outsourcing arrangements. These issues are evaluated together with the characteristics of the firms and the specific project outsourced.     

CO2 emissions embodied in China’s export

ABSTRACT

The reduction of CO₂ emissions embodied in export will have an important role for China to achieve its CO₂ emissions peaking target. In this study, we use input–output analysis to examine the embodied CO₂ emissions in China’s export to its top largest trading countries from 2008 to 2015. We find that China’s exported CO₂ emissions peaked in 2008. More than 70% of embodied CO₂ emission were exported to only 20 countries, and CO₂ emissions exported to developing countries have been increasing. High-energy consumption sectors contribute to CO₂ emissions embodied in export significantly, such as Electricity, Gas and Water. We conclude that structural adjustment could be considered alongside technological improvements to curb China’s growing CO₂ emissions.     

Optimal price‐level drift under commitment in the canonical New Keynesian model

Abstract In both the canonical and many extended versions of the New Keynesian model, optimal monetary policy under commitment implies price‐level stationarity as long as expectations are rational. We show that this is no longer the case if the central bank and private agents make decisions before observing current shocks. The optimal amount of price‐level drift in response to unexpected innovations to inflation is quantitatively important. This result has important implications for monetary policy, including the design of the optimal loss function for the central bank if it cannot commit to its future policies.     

The role of outsourcing in driving global carbon emissions

Globalisation has narrowed the gap between producers and consumers of goods and services. The linkages between international trade and carbon dioxide (CO₂) emissions have started to be recognised, yet the extent of outsourcing of emissions across nations is unknown. Filling this gap in knowledge is critical for designing effective policy mechanisms for assigning responsibility for reductions in emissions. Here we present a structural decomposition analysis of global trends in outsourcing of emissions from 1990 to 2010 for 186 individual countries. To this end, we disaggregate total CO₂ emissions for each country into contributions from the domestic economy and international trade. This allows us to unveil outsourcing trends for all nations confirming a world-wide shifting of emissions-intensive production across borders. We categorise nations into “outsourcers” – countries that outsource carbon-intensive production to so-called contractor nations. Our detailed assessment of the commodity content of global outsourcing flows reveals interesting insights about the trade of carbon-intensive commodities.
