With the help of five Republicans in the US Senate, it appears the hurdle has been cleared for some form of a jobs bill to pass approval in Congress. Perhaps I am mistaken, but Congress already passed and the president signed a $750 billion spending bill to get people back to work. What is different about raiding an empty treasury of billions more this time to create jobs?

Architects of the legislation point to the tax credits available to businesses that increase their headcount. One idea is to give employers a tax-credit up to $5000 for each additional person hired. At first glance this may seem like a logical incentive. But as my economic students learn, two sides exist to transaction.

The tax credit will only reduce the marginal cost of a new employee for the first year. After the initial year the cost of the new hire will balloon by at least the amount of the tax credit. As any student passing a Principles of Economic realizes, cost is just one factor in the employment equation. The other side of the coin takes into account the revenue benefit that an employee brings to the table. Firms will retain or hire individuals as long as their additional benefit exceeds their additional cost. Without a significant pick up in demand, many firms will pass on expanding their payrolls.

Small business owners point to another flaw of the proposal in that tax-credits are realized at the end of the year. The cost of a new hire drains cash flow in the meantime. As one owner stated, cash flow is at the heart of staying in business. My creditors may not wait for the federal government to reimburse me.

It looks like another lesson in failed Keynesian economics.
