Electricity has been regarded as a typical example of a general purpose technology and important for the surge both in energy productivity and overall productivity in the American economy in the 1920s. This view was challenged by Nicholas and Moser (2004) based on patent statistics. We argue...

The paper explores development blocks around electrification at a 14 sector level in the Swedish economy 1900-1974. We suggest that long-run cointegration relations in combination with mutually Granger-causing short-run effects form a development block. One block centred on electricity that...

Efficiency in energy use is crucial for sustainable development. We use cointegration analyses to investigate the effect of electricity on energy productivity in Swedish industry 1930-1990. Electricity augmented energy productivity in those industrial branches that used electricity for multiple...
