Forecasting gross value-added at the regional level: are sectoral disaggregated predictions superior to direct ones?

Are Heterogeneous Cellular Networks Superior to Homogeneous Ones?

In this paper, the performance of homogeneous cellular networks (HMCNs) and heterogeneous cellular networks (HTCNs) is evaluated and compared. The HTCN discussed in this paper consists of three kinds of cells: macrocells, microcells and femtocells. The macrocells are evenly deployed. The microcells are densely deployed in the offices and public areas and sparsely deployed in the universities ar...

Trade Costs and Gravity for Gross and Value Added Trade

Cross-border production fragmentation enables countries to export domestic value added not only directly in the form of gross exports of final goods, but also indirectly by participating in global supply chains. This paper studies the determinants of trade in value added. I incorporate the global input-output structure into an international trade model to derive an approximate gravity equation ...

The Added Value of Value Added Tax

Raising domestic tax revenues is a priority for most sub-Saharan African countries. But the tax bases in most African countries are undermined by widespread tax avoidance and evasion. A new study from CMI supports the claim that improved knowledge about the tax system makes a difference in people’s willingness to pay tax. The study shows that exposure to Value-AddedTax (VAT) makes people take a...

Optimized Clusters for Disaggregated Electricity Load Forecasting

• To account for the variation of EDF’s (the French electrical company) portfolio following the liberalization of the electrical market, it is essential to disaggregate the global load curve. The idea is to disaggregate the global signal in such a way that the sum of disaggregated forecasts significantly improves the prediction of the whole global signal. The strategy is to optimize, a prelimin...
