A Times investigation has examined and tallied thousands of local incentives granted nationwide and has found that states, counties and cities are giving up more than $80 billion each year to companies. The beneficiaries come from virtually every corner of the corporate world, encompassing oil and coal conglomerates, technology and entertainment companies, banks and big-box retail chains.

The cost of the awards is certainly far higher. A full accounting, The Times discovered, is not possible because the incentives are granted by thousands of government agencies and officials, and many do not know the value of all their awards. Nor do they know if the money was worth it because they rarely track how many jobs are created. Even where officials do track incentives, they acknowledge that it is impossible to know whether the jobs would have been created without the aid.

“How can you even talk about rationalizing what you’re doing when you don’t even know what you’re doing?” said Timothy J. Bartik, a senior economist at the W.E. Upjohn Institute for Employment Research in Kalamazoo, Mich.

The Times analyzed more than 150,000 awards and created a searchable database of incentive spending. The survey was supplemented by interviews with more than 100 officials in government and business organizations as well as corporate executives and consultants.

A portrait arises of mayors and governors who are desperate to create jobs, outmatched by multinational corporations and short on tools to fact-check what companies tell them. Many of the officials said they feared that companies would move jobs overseas if they did not get subsidies in the United States.

Over the years, corporations have increasingly exploited that fear, creating a high-stakes bazaar where they pit local officials against one another to get the most lucrative packages. States compete with other states, cities compete with surrounding suburbs, and even small towns have entered the race with the goal of defeating their neighbors.

While some jobs have certainly migrated overseas, many companies receiving incentives were not considering leaving the country, according to interviews and incentive data.

“If you’re looking at the competitiveness of a region, the most important thing a region can do is to focus on education. And this use of incentives is really transferring money from education to businesses.”

Despite their scale, state and local incentives have barely been part of the national debate on the economic crisis. The budget negotiations under way in Washington have not addressed whether the incentives are worth the cost, even though 20 percent of state and local budgets come from federal spending. Lawmakers in Washington are battling over possible increases in personal taxes, while both parties have said that lower federal taxes on corporations are needed for the country to compete globally.

The Times analysis shows that Texas awards more incentives, over $19 billion a year, than any other state. Alaska, West Virginia and Nebraska give up the most per resident.

For many communities, the payouts add up to a substantial chunk of their overall spending, the analysis found. Oklahoma and West Virginia give up amounts equal to about one-third of their budgets, and Maine allocates nearly a fifth.

In a few states, the cost of incentives is not significant. But several of them have low business taxes — or none at all — which can save companies even more money than tax credits.

Far and away the most incentive money is spent on manufacturing, about $25.5 billion a year, followed by agriculture. The oil, gas and mining industries come in third, and the film business fourth. Technology is not far behind, as companies like Twitter and Facebook increasingly seek tax breaks and many localities bet on the industry’s long-term viability.
