摘要：This paper estimates the costs of a government mandate to use natural gas vehicles, focusing on the less desirable attributes that these vehicles possess. A model of producer and consumer behavior in a market for a differentiated product is constructed; a hedonic price function is estimated; and consumer surplus losses from the substitution of natural gas cars for gasoline cars are calculated. These losses are found to be significant: the average per car consumer surplus loss ranges from $1100...

The notion that the efficiency of large scale of production is brought about mainly by a larger size capital stock or a more advanced one is not new.

摘要：Ophem (1993) employed a switching regression model with earnings entering the choice equation to investigate earnings differentials between the public and private sectors. Ophem also described a ''modified switching regression model'' in which only the equation for unknown earnings is substituted into the choice equation. He argued the coefficients in the choice equation can be identified in the modified switching regression model without exclusion restrictions and estimates from the modified ...
