Investing in Biogas: Timing, Technological Choice and the Value of Flexibility from Inputs Mix
Moretto, Michele; Corato, Luca Di - Fondazione ENI Enrico Mattei (FEEM) - 2009
In a continuous-time framework we study the technology and investment choice problem of a continuous co-digestion biogas plant dealing with randomly fluctuating relative convenience of input factor costs. Input factors enter into the productive process together mixed according to a given initial...

Energy Intensity Developments in 40 Major Economies: Structural Change or Technology Improvement?
Cian, Enrica De; Schymura, Michael; Verdolini, Elena; … - Fondazione ENI Enrico Mattei (FEEM) - 2013
This study analyzes energy intensity trends and drivers in 40 major economies using the WIOD database, a novel harmonized and consistent dataset of input-output table time series accompanied by environmental satellite data. We use logarithmic mean Divisia index decomposition to (1) study trends...

The Market Value of Variable Renewables
Hirth, Lion - Fondazione ENI Enrico Mattei (FEEM) - 2012
The income that wind and solar power receive on the market is affected by the variability of their output. At times of high availability of the primary energy source, they supply electricity at zero marginal costs, shift the supply curve (merit-order curve) to the right and thereby reduce the...

Estimating Feedback Effect in Technical Change: A Frontier Approach
Otto, Vincent M.; Kuosmanen, Timo; Ierland, Ekko C. van - Fondazione ENI Enrico Mattei (FEEM) - 2006
This study examines whether today’s technical change depends on yesterday’s technical change. We propose to investigate this feedback effect by using the technical-change component of the Malmquist productivity index. This approach can overcome some problems in alternative patent-citation...

Unbundling Technology Adoption and tfp at the Firm Level. Do Intangibles Matter?
Battisti, Michele; Belloc, Filippo; Gatto, Massimo Del - Fondazione ENI Enrico Mattei (FEEM) - 2012
We use a panel of European firms to investigate the relationship between intangible assets and productivity. We disentangle between tfp and technology adoption, while available studies so far have considered only a notion of productivity conflating the two effects. To this aim, we estimate...

Business Groups as Hierarchies of Firms: Determinants of Vertical Integration and Performance
Altomonte, Carlo; Rungi, Armando - Fondazione ENI Enrico Mattei (FEEM) - 2013
We explore the nature of Business Groups, that is network-like forms of hierarchical organization between legally autonomous firms spanning both within and across national borders. Exploiting a unique dataset of 270,474 headquarters controlling more than 1,500,000 (domestic and foreign)...
