We perform an analysis of tail index estimation through Monte-Carlo simulations of synthetic data, in order to evaluate several tail estimators proposed in the literature. We derive and discuss the error of the Hill estimator under a general tail expansion of the distribution function. The...

Liquid markets generate hundreds or thousands of ticks (the minimum change in price a security can have, either up or down) every business day. Data vendors such as Reuters transmit more than 275,000 prices per day for foreign exchange spot rates alone. Thus, high-frequency data can be a...

On December 18, 2010, Iran increased domestic energy and agricultural prices by up to 20 times, making it the first major oil-exporting country to reduce substantially implicit energy subsidies. This paper reviews the economic and technical issues involved in the planning and early...

Using an applied general equilibrium of the Swiss economy the economic consequences of an environmental tax reform are analysed. Such a reform is followed by a substantial reduction of CO2 emissions and the use of non-renewable energy (first dividend), and a reduction of involuntary...

We present a toolbox to compute and extract information from inhomogeneous (i. e. unequally spaced) time series.The toolbox contains a large set of operators, mapping from the space of inhomogeneous time series to itself. These operators are computationally efficient (time and memory-wise) and...
