As the Obama administration plans a large stimulus spending plan that may approach $1 trillion over several years, considering also the second phase of the $800 billion first phase stimulus, there is a concern that there may be wasteful spending and social costs of borrowing and spending by the government of such proportions. In economics jargon this hinges on whether there is amultiplier effect of spending, higher if its efficiently and well spent with less impact on private consumption and investment, and lower if the opposite were true. The assumption behind amultiplier of 1.0 for an additional bridge or road is that resources like manpower and capital that would be otherwise idle are deployed to produce something useful. An increase in one unit of government purchases increases by one unit the real gross domestic product. The government has effectively created the additional bridge or road without a cut in anybody's consumption or a businesses investment. The other contrasting approaches are to say there is a multiplier of zero, meaning there is a social cost in two ways. One the reduction of consumption and the crowding out of businesses investing in new products and technologies for example, and second in the inefficent use of resources if a government bureaucracy is put to work allocating money and the additional dangers of favoritism and corruption. To say that there is a multipier of 1.5 would mean that the government figures out a way to get private investment through conversion of plants for automotive parts say to make wind turbine blades by giving incentives, tax benefits and grants, spends on a dilapidated road and public transportation infrastructure that may provide benefits in increased growth capacity over future years. The limits of a government bureaucracy and inefficiency of government would in this case be addressed by transparency rules adopted and measures that track progress that are freely available to all citizens say on a website on the internet, and by bringing in fresh management talent from the private sector. There appears to be no generalization that can be applied for one multiplier for all projects. It may be that the multiplier will vary with the project. Some projects like the conversion of a factory making unneeded auto parts to a badly needed wind energy part, to change the dynamics of energy market pricing, to meet energy needs and cut emissions, may end up having a multiplier much above 1.0. A redundant or less needed bridge has a lower multiplier than a bridge rebuilt before it leads to breakdown. And also the complication that too large a movement in one direction say of stimulus spending, might result in a shift of the curve towards a smaller multiplier and diminishing returns, as the resources to track such a large expenditure and the talent to adminster are overextended. The social cost of private investment not making that investment in new technology, new product or improved product has to be figured into all this, both at the conceptual level as all costs and benefits may not be picked up in the analysis, and at the macro level keeping in mind that the animal spirits, as they were once described, may just not be there to absorb the huge outlays which a government can make. These do not come without an opportunity cost and borrowing costs. All this leads one to to conclude that spending has to be carefully evaluated and projects assessed on a case by case basis for costs and benefits. The spending has to be balanced to provide just as many incentives for private investment to invest in new products and technologies. One way the Obama team is attempting to address this is to include a $300 billion tax cut for businesses and individuals. The business tax cuts are aimed at helping small business with losses, and for future investments and making hires and forgoing layoffs. The other part relates to careful evaluation of spending projects and transparency so the people can see if they are effective. See the link to this....
