GENDER AWARENESS IN RESEARCH AND POLICY MAKING

Abstract

There is an assumption that we can enhance peacebuilding by improving the tools that we use for assessments, planning and evaluation. However, the focus on tools creates the impression that peacebuilding challenges are technical. Improving tools is not meaningless, but our preoccupation with tools has a negative effect when it becomes a front for avoiding dealing with the deeper inherent contradictions in peacebuilding. There are limits to our knowledge and our ability to engineer specific outcomes in complex systems. There are unrealistically high expectations of coherence, unity of purpose and cooperation among peacebuilding actors. Peacebuilding agents are interconnected, but that does not imply that they have the same objectives, mandates, principles and values. Interconnected problems call for interconnected responses, not for one coherent response. Coherence should not be about negotiating a common position, and then promoting it regardless of changing dynamics. Coherence should be about continuously managing competing interests and interdependencies. The interaction between dissention, competition for resources, and the tension between different approaches and policy choices is not only normal but necessary to ensure the optimal functioning of the system.     

Does Geopolitical Risks Predict Stock Returns and Volatility of Leading Defense Companies? Evidence from a Nonparametric Approach

Abstract

We use the k-th-order nonparametric causality test at monthly frequency over the period of 1985:1 to 2016:06 to analyze whether geopolitical risks can predict movements in stock returns and volatility of 24 global defense firms. The nonparametric approach controls for the existing misspecification of a linear framework of causality, and hence, the mild evidence of causality obtained under the standard Granger tests cannot be relied upon. When we apply the nonparametric test, we find that there is no evidence of predictability of stock returns of these defense companies emanating from the geopolitical risk measure. However, the geopolitical risk index does predict realized volatility in 50% of the companies. Our results indicate that while global geopolitical events over a period of time is less likely to predict returns, such global risks are more inclined in affecting future risk profile of defense firms.     

Geopolitical Risks and Movements in Islamic Bond and Equity Markets: A Note

This study applies a non-parametric causality-in-quantiles test to examine the causal effect of geopolitical risks on return and volatility dynamics of Islamic equity and bond markets. Geopolitical risks are generally found to impact Islamic equity market volatility measures, rather than returns. However, geopolitical risks tend to predict both returns and volatility measures of Islamic bonds. Interestingly, causality, when it exists for returns and/or volatility of Islamic equities and bonds, is found to hold over entire conditional distributions of returns and volatilities, barring the extreme ends of the same.
