Nearly every U.S. state has environmental provisions in its constitution. These provisions cover a wide range of issues concerning the manner in which the environment and natural resources are to be governed (e.g., public funding, eminent domain, public trust, access to water, legislative...

Empirical researchers often have to map data provided for a "reporting" spatial unit, say counties in 1900, to a "reference" one, say, counties in 2010. We discuss a general method to create such crosswalks: computing the share of the area of each reporting unit nested in a given reference unit....

This articles examines what role natural factors play in explaining cross-country differences in carbon dioxide emissions. Natural factors mean here differences in the climatic conditions, the transportation requirements as well as in the availability of renewable and fossil fuel resources....

Patent data provide an increasingly used means to analyse innovation performance worldwide including in countries with incomplete data coverage, such as some developing countries. This paper discusses the specific issues associated with using patent data for measuring and analysing innovation in...

This study empirically investigates the existence or not of Environmental Kuznets Curve (EKC) hypothesis in Nordic and Non-Nordic European countries, with carbon dioxide emissions (and ecological footprint for robustness tests) as proxy of environmental quality. The data are spanning from the...

This paper deals with the construction, decomposition and comparison of water footprint time series in 40 countries and one aggregate macro-region, in the period 1995-2009. The analysis of the different “footpaths” allows us to investigate on the possible causes behind the time evolution of...

China is appraised to have the world's largest exploitable reserves of shale gas, although several legal, regulatory, environmental and investment-related issues will likely restrain its scope. China's capacity to successfully face these hurdles and produce commercial shale gas will have a...
