1. Effect of hedging on cash holdings. Corporations care for liquidity buffers to smooth cash flow shocks in adverse market conditions. Especially, the cash flows of electric utilities are heavily impacted by seasonal weather conditions: for example, in a hotter-than-usual summer, electricity demand boosts the earning of electric utilities (e.g., everybody turns on their air conditioners), whereas in a cooler-than-usual summer, electric utilities may suffer from poor earnings. The exposure to such weather risk depends on where each electric utility is located: utilities located in stable weather regions (low weather volatility) may not face much cash flow uncertainty due to weather conditions, whereas those located in volatile weather regions (high weather volatility) may face great cash flow uncertainty due to weather conditions. In 1997, weather derivatives were introduced for firms to hedge such weather risk. That is, firms are able to buy weather derivative contracts that pay when seasonal weather is milder than usual. 30 Cash/assets (%) 25 20 15 10 5 0 High Weather Volatility Low Weather Volatility 1990 1991 1992 1993 1994 1995 1996 1997 1998 1999 2000 Based on the plot above, what is the net effect of weather derivatives on cash holdings of electric utilities (i.e., how much does the availability of weather derivatives increases or decreases cash holdings divided by assets)?
