520 $a In the second chapter, we show that sabotage may be particularly profitable for a vertically-integrated provider (VIP) when its downstream rival can devote effort to reducing its operating costs. Demand-reducing sabotage limits the return the rival anticipates from its cost management activities, and thereby inhibits those activities. The resulting higher costs for the rival increase the VIP's profit in settings where sabotage would not be profitable if the rival could not manage its operating costs. To limit sabotage by the VIP, the rival may find it profitable to intentionally diminish its ability to reduce its production costs. The diminished ability can produce Pareto gains.
520 $a In the third chapter, I examine the market power in the PJM spot energy market from 2010 to 2014. I estimate the elasticity adjusted price cost margin as a measure of market power, accounting for the fluctuating price elasticity of demand in the market. I find that market price was above competitive level but not as high as Cournot model predicts. Elasticity adjusted price cost margin varied over time and across firms. Inelastic demand can drive up conventional price cost margin but not necessarily the elasticity adjusted price cost margin. Among the ten large firms in the PJM wholesale market, I find firms with higher percentage of peaking generation capacity had higher elasticity adjusted price cost margin. These peaking power plants exercised excessive market power because they can typically only recover their capital costs in a short time, when they operate during the peak demand hours.
