That makes sense since they are the two largest purchases consumers make, usually with most of the purchase price financed, significantly multiplying the economic effect of the cash down payment, while increased home construction and auto production results in significant new business for the long stream of suppliers to those industries.
In the case of the oil company, for instance, the cost of land corresponds to the premium (or down-payment) on a call option, and the extra investment needed to start production to its strike price (at which the option is exercised).
The air force base did not have to provide any upfront payment on the ten-year contract, and will only make a fixed rate once energy production starts.
