FUTURE PROJECTS

Asymmetry and Leptokurtosis in Financial Data

Many studies found that financial data exhibits non-normal characteristics such as Asymmetry and Leptokurtosis. Though the third-moment or skewness has been studied. there is not yet a good in-depth analysis in fourth moment or leptokurtosis. This study aims to provide an extensive literature on leptokurtosis discuss the importance and use of this measure in relation to financial data and develop suitable tests for testing kurtosis in the presence/absence of skewness.

Application invited for: a PhD candidate who is keen to explore this topic for his thesis. Candidate should have a strong b

Use of Pearson family distribution in modeling economics and financial data

Pearson family of distributions has not been used extensively in economics though there are few applications in finance. The objective of this study is to explore the behavior of economics data in relation to this family of distributions.

Application invited for: PhD candidate who is willing to start his PhD in economics or Finance at UBD. Strong background in

Developing a new sensitivity measure for market risk

This study aims to search for a new sensitivity measure that can explain the behavior of returns and volatility. Using some preliminary work available in the literature a measure can be developed theoretically and tested empirically.

Application invited for: Master by research and PhD candidates. Some empirical work of this topic can be done by a student wh
