Despite the worldwide popularity of CDD- and HDD-type weather derivatives on temperature, a different class of weather derivatives, the so-called summer days options, is more popular in Japan, whose payoffs are determined by the number of summer days (i.e., the days whose average temperature is...

We analyze transition probabilities of regime-switching in electricity prices based on supply and demand by using the structural model of Kanamura and Ohashi (2004). We show that the transition probabilities depend on the demand level and thus are not constant. This result is in sharp contrast...
