In this paper a case study is presented to propose an alternative mechanism to include the impact of climate change into the hydropower projects’ feasibility valuation. We started from an independent engineer historical energy generation simulations; therefore, applying mixing unconditional...

In this work we propose a new estimator for Zenga's inequality measure in heavy tailed populations. The new estimator is based on the Weissman estimator for high quantiles. We will show that, under fairly general conditions, it has asymptotic normal distribution. Further we present the results...

We criticize the theories used to explain the size distribution of cities. They take an empirical fact and work backward to obtain assumptions on primitives. The induced theoretical assumptions on consumer behavior, particularly about their inability to insure against the city-level productivity...

In this paper we estimated not-overlapped monthly historic standard deviations of the S&P 500 Index returns for the period 1950 – 2009, then using extreme value theory we defined extreme volatility events and introduced an alternative “fear scale” that is compared with the “fear index”.

Extreme returns in stock returns need to be captured for a successful risk management function to estimate unexpected loss in portfolio. Traditional value-at-risk models based on parametric models are not able to capture the extremes in emerging markets where high volatility and nonlinear...
