Impact of Caligus Treatments on Unit Costs of Heterogenous Salmon Farms in Chile

Submitted by NENRE Concepcion on

We measure the impact that sanitary treatments that control ectoparasite Caligus rogercresseyi abundance have on unit production costs of Salmo salar farms in Chile. We follow complete production cycles for a sample of farms between 2009 and 2015. We estimate a simultaneous salmon biomass growth and Caligus abundance model. The statistical analysis determines the effect of antiparasitic treatments, location of farms, environmental conditions and Caligus abundance on the salmon growth profile.

Costos Económicos de las Externalidades Ambientales del fracking: un análisis de metaregresión y algunas implicaciones para Colombia

Submitted by Manuela Fonseca on

La cuantificación monetaria de las externalidades ambientales derivadas de la explotación de hidrocarburos no convencionales que utiliza la técnica de fracturación hidráulica o fracking muestra una alta variabilidad pues sus costos no están unívocamente determinados. En este documento desarrollamos un análisis de metarregresión sobre los posibles efectos económicos atribuibles a la proximidad de entornos que puedan verse afectados ambientalmente por el fracking.

Forward contracts in electricity markets and capacity investment: A simulation study

Submitted by Manuela Fonseca on

This simulation study analyzes the effect of the introduction of forward markets to mitigate cyclical price behavior in electricity markets from a dynamic extended Cobweb model. We pay particular attention to the effect of lags in investment decisions and the effect of not fully replacing retired capacity in electricity markets. In line with previous research, the introduction of forward markets decreases price variability in comparison to a spot market.
