“…On the other side of this debate, Baumert (1999), Lutter (2000), Kim and Baumert (2002), Strachan (2007), and Kolstad (2005) all find merit in the concept of intensity-based caps because of the reduction in uncertainty in the economic outcome gained by indexing the cap to GDP and, crucially, the effect on the willingness of countries to participate in international agreements. Baumert (1999), Lutter (2000), and Lisowski (2002) also see intensity limits as a means to avoid the ''hot air'' resulting from overly generous absolute caps that might be needed to reassure acceding countries that the emissions limit would not place undue costs on them in the event of greater than expected economic growth. Along these lines, Jotzo and Pezzey (2007) provide a theoretical analysis and simulations of binding absolute and intensity caps in which parties are assumed to posses varying degrees of risk aversion to unexpectedly high-cost outcomes with particular attention given to developing country participation.…”
