Some people still seem to think Republicans take a hands-off approach to regulation, probably because the party is always quick to criticize the burdens regulations place on businesses. But Republican rhetoric doesn't always match Republican policy. In 2007, according to Wayne Crews of the Competitive Enterprise Institute, roughly 50 regulatory agencies issued 3,595 final rules, ranging from boosting fuel economy standards for light trucks to continuing a ban on bringing torch lighters into airplane cabins. Five departments (Commerce, Agriculture, Homeland Security, Treasury, and the Environmental Protection Agency) accounted for 45 percent of the new regulations.
Since Bush took office in 2001, there has been a 13 percent decrease in the annual number of new rules. But the new regulations' cost to the economy will be much higher than it was before 2001. Of the new rules, 159 are "economically significant," meaning they will cost at least $100 million a year. That's a 10 percent increase in the number of high-cost rules since 2006, and a 70 percent increase since 2001. And at the end of 2007, another 3,882 rules were already at different stages of implementation, 757 of them targeting small businesses............
Overall, the final outcome of this Republican regulation has been a significant increase in regulatory activity and cost since 2001. The number of pages added to the Federal Register, which lists all new regulations, reached an all-time high of 78,090 in 2007, up from 64,438 in 2001.
Figure 1 shows the real increase in regulatory spending by full presidential term between 1960 and 2009. During both his terms, President Bush outspent every one of his recent predecessors. In his first term, he increased spending on regulatory agencies by $8.3 billion, almost doubling what President Clinton—the second biggest spender—spent during his second term.
The data also show that, adjusted for inflation, expenditures for the category of finance and banking were cut by 3 percent during the Clinton years and rose 29 percent from 2001 to 2009, making it hard to argue that Bush deregulated the financial sector.
