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.
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.
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.

We are witnessing the digital transformation of businesses that have spread across products or services, processes and deliveries. New business models that take advantage of digitation are growing fast and digital platforms spring up in many parts of the world. As digital platforms rely on collaborative actors, viewing a digital firm in isolation may not be appropriate. As such, considering a digital platform in its value-exchange networks business ecosystem is more suitable to get the big picture of the platform and then analyze how the platform interacts with its surroundings in the ecosystem to keep the balance and expand. The research is expected to produce a novel model for digital business ecosystem using a value exchange network construct. Application of the model to a various digital ecosystems will be studied.
