Threshold Effects of Energy Price Changes [PDF]
SSRN Electronic Journal, 2000 This paper presents a theoretical model emphasising energy investments’characteristics of uncertainty and irreversibility. The theoretical modelsuggests threshold effects. Firms are induced to substitute away from energyonly if prices of energy exceed a certain threshold level and they reverse thetechnology only if energy prices are low enough ...
