Non-parametric approach to financial time series jump estimation, using the L-Estimator, is compared with the parametric approach utilizing a Stochastic-Volatility-Jump-Diffusion (SVJD) model, estimated with MCMC and extended with Particle Filters to estimate the out-sample evolution of its...

This paper proposes a novel time-varying present-value model to analyze the joint dynamics of stock returns and cash flows periodically. We use a nonparametric time-varying vector autoregressive model to examine the economic implications of the time-varying present-value model. By conducting...

This paper introduces a new family of portmanteau tests for serial correlation. Using the wavelet transform, we decompose the variance of the underlying process into the variance of its low frequency and of its high frequency components and we design a variance ratio test of no serial...

Mansur Masih3 Abstract This research studies the benefit of the practice of Restricted Short Selling (RSS) on the Islamic stocks. Benefit is defined as the influence of the application of RSS on the stock returns and ultimately, on the market. Malaysia is used as a case study. Using dynamic...

This study tests the random walk hypothesis in the spot prices of the petroleum products markets. Under the variance ratio test, a less restrictive random walk process namely the martingale process is examined over the period 1998-2008. The variance ratio methodology is capable of providing...

Due to its non-storable nature, electricity is a commodity with probably the most volatile spot prices, exemplified by occasional spikes. Appropriate pricing, portfolio, and risk management models have to incorporate these characteristics, and the spikes in particular. We investigate the nature...

Germany has an ambitious climate target for 2030 that cannot be achieved without reducing the high share of coal in power generation. In the face of this, the country has set up a commission to phase out coal. A UK-style carbon price floor is one of the options being considered. Yet implementing...

This paper provides an empirical test of the Coase Theorem. I analyze whether emissions are independent from allowance allocations in the electricity sector regulated under the EU's Emissions Trading System (EU ETS). Exogenous variation in levels of free allocation for power producing...

European energy crisis has three elements: skyrocketing prices for energy carriers such as natural gas, coal, as well as electricity, reduced nuclear power plant availability in France, and lower hydro power generation in Europe. This paper decomposes the effects of those elements on power...

I investigate the impact of the European Union Emissions Trading Scheme (EU ETS) on fuel efficiency of fossil fuel power plants using administrative micro data on power plants in Germany from 2003 to 2012. I find positive efficiency effects in fuel use, leading to a decrease in fuel input of 0.4...
