Fuel poverty may become an increasingly severe problem in developed countries in cases when real prices for fossil fuels increase at high rates or when real energy prices increase due to policies for greenhouse gas abatement. Fuel poverty measurement consists of two largely independent parts,...

Measures of affordability are applied in practice, e.g., to assess the affordability of energy services, water or housing. They can be interpreted as measures of deprivation in a specific domain of consumption. The large body of literature on affordability measure has little overlap with the...

Due to potential abuse of the market power at wholesale and retail market level for natural gas the Federal Cartel Office in Germany prohibited further forward integration of gas importing firms with retail incumbents from 2005/2006 to 2010. The Authority argued that the very few dominant gas...

This paper focuses on finding starting-values for maximum likelihood estimation of Vector STAR models. Based on a Monte Carlo exercise, different procedures are evaluated. Their performance is assessed w.r.t. model fit and computational effort. I employ i) grid search algorithms, and ii)...

We develop an agent-based model in which heterogenous and boundedly rational agents interact by trading a risky asset at an endogenously set price. Agents are endowed with balance sheets comprising the risky asset as well as cash on the asset side and equity capital as well as debt on the...

We formulate an optimal control capital accumulation model with a Leontief-type production function and an exogenously given time-lag between investment and the accumulation of the capital stock, to analyze the qualitative and quantitative influence of time-lags on the system dynamics. As known...

We present a decomposition approach for integrated assessment modeling of climate policy based on a linear approximation of the climate system. Our objective is to demonstrate the usefulness of decomposition for integrated assessment models posed in a complementarity format. First, the...

Sensitivity analysis studies how the variation in the numerical output of a model can be quantitatively apportioned to different sources of variation in basic input parameters. Thus, it serves to examine the robustness of numerical results with respect to input parameters, which is a...

We decompose the economic implications of the Kyoto Protocol at the cross-country level, splitting the total economic impact for each region into contributions from its own emission abatement policy and those from other regions. Our analysis which is based on a large-scale computable general...
