The Candidates are Starting to Talk Econ

We are rapidly approaching what is one of the most predictably awful exercises in a presidential campaign. The candidates are about to present their economic “plans”. We can expect the candidates to recite the usual pieties about tackling the deficit, and eliminating waste, fraud and abuse. At the same time they will save social security and Medicare, and create good paying middle-class American jobs in manufacturing.


For some reason or other the notion that the President can “manage” the economy has taken hold of the body politic like a dog on a mailman’s ankle. While it is certainly true that good economic policy will encourage economic growth, innovation and wealth creation, it is just as true that bad economic policy will tend to discourage those results. Which is to say that government can set the conditions that individuals and firms need to prosper, but that government is utterly incapable of doing much more than that.


The basic conditions that are necessary (but not sufficient) for prosperity are well known. They include free and competitive markets, the rule of law, an independent judiciary and protection of property rights, contract enforcement, sensible regulations, low taxes, neutral monetary policy, and political stability. Beyond that, government intervention generally results in more harm than good.


For example, the idea that government is going to “create jobs” and raise (real) wages is simply nonsense. Entrepreneurs and businesses create jobs as they seek to make profits. Real wages eventually rise (or fall) to the point where they equal marginal productivity. Firms assume the risks of hiring workers when they see the possibility to profit by creating new goods and services, or by improving on existing ones. They do not create jobs for their own sake. In fact businesses try to minimize inputs (like labor and capital) with respect to outputs. That’s how they maximize profits, which is the point of the enterprise.


On the other hand, government is incapable of creating jobs on balance, except insofar as those jobs are necessary to allow the larger economy (and society) to function efficiently and effectively. Sure, a government agency can hire somebody to dig holes in the sand and then hire someone else to fill the holes back in. But, with apologies to Lord Keynes, that doesn’t really create net employment because no wealth is created. Resources are just wasted. The money spent in make-work projects could have been spent on productive activity that actually created wealth. That would result in economic growth and greater opportunity.


Every dollar that government spends is a dollar taken from the private sector. With that in mind there are two tests that should be applied to the candidates’ economic policy proposals. First, is the policy directed at producing a public good. A public good is defined as one where (a) consumption is non-rival and (b) the costs of excludability are prohibitively high. For example, the classic example is defense. We all benefit from defense, and one citizen’s protection does not detract from another’s. Consumption is therefore non-rival.

On the other hand, only one of us can eat a given ice cream cone. An ice cream cone stands as a private good in contrast to defense, which is a public good.


The question of excludability of consumption addresses the problem of free riders. A classic example here is a lighthouse. The idea is that once the lighthouse is built, it is virtually impossible to stop a ship from using its beacon even if the ship hasn’t paid a fee. Since free-riders can’t be stopped from using the lighthouse’s services, the returns from building lighthouses are less than they should be, so fewer than the optimal quantity of lighthouses get built. The argument is that government should step in and supply lighthouses to rectify market failure.


(However, it is worth noting that in The Problem of the Lighthouse, economics Nobel laureate Ronald Coase pointed out that the problem could easily be solved by checking ships registries and charging on that basis.)


After the public goods question is resolved, the second test comes to the fore, namely the question of opportunity cost. Every dollar government spends is taken from the private sector, either directly by taxation, or indirectly by borrowing in competition with the private sector. So each dollar government spends should produce more goods and services (that the citizens actually want) than would have been produced by the private sector, had government not acted.


So we have three basic criteria for evaluating the candidate’s economic policy proposals. Are the policy proposals aimed at producing public goods as opposed to private benefits? Will the diversion of private sector funds to the public sector produce a result in a net output gain? Will the candidate’s respective economic proposals serve to strengthen or weaken the conditions necessary for prosperity?

These are the criteria that On Liberty Watch will use to evaluate the economic policy proposals of the candidates.

    What would your comment be regarding Paul Krugman’s Aug 8 opinion piece where he advocates deficit spending for infrastructure. We do need to repair bridges all around the country:

    There are, of course, many ways our economic policy could be improved. But the most important thing we need is sharply increased public investment in everything from energy to transportation to wastewater treatment:

    From the editorial:

    How should we pay for this investment? We shouldn’t — not now, or any time soon. Right now there is an overwhelming case for more government borrowing…

    …First, we have obvious, pressing needs for public investment in many areas. In Washington, the aging Metro is in such bad shape that whole lines may have to be shut down for maintenance. In Florida, green slime infests beaches, in large part because failure to upgrade an 80-year-old dike or to purchase more land as a runoff area is forcing the Army Corps of Engineers to release polluted water from Lake Okeechobee. There are similar stories all across America.

    The argument about public infrastructure is kind of interesting not least because of what is usually omitted from the discussion. But first as background, let us stipulate that public infrastructure generally consists of classic public goods, and as such meets the first criteria for public spending. So let’s go to the second set of criteria and ask the proper questions: how much, on what projects, who decides, and how is it financed?

    Let’s look at some data, available at this link to the CBO:

    State and local governments do the majority of public spending on infrastructure. In 2014, a typical year, public infrastructure spending amounted to $416 billion, of which $320 billion was state and local, and $96 billion was federal. That is as it should be. Why should Oregonians finance bridges in Pennsylvania? People in those states and communities decide what to build and how to pay for it in their own jurisdictions.

    As for Krugman: He says there that many places [“…have obvious, pressing needs for public investment…”]. Then those places should obviously pay for them since they are local responsibilities. The Washington Metro system he references is a local responsibility, as are the subway systems of New York, Chicago etc.

    And then he travels into boondoggle territory. A combination of big public investments (by which he means federal spending) and low interest rates he suggests, may spur sufficient growth to pay for said investments. Well, this is the very same Paul Krugman that was cheering for all those non-existent “shovel-ready” jobs that were going to spur growth back in 2009. How did that work out? Not so well, considering the bill was around $900 billion and growth remains exceedingly slow.

    But let’s go on a little further. Why is all this (unspecified) spending supposed to be directed from Washington D.C.? Is there, or are there, specific projects that only the federal government is able to finance and manage? If so, what are they? And let’s not forget, even if Krugman chooses to, that every dollar that government spends is a dollar taken from the private sector. Why are we to assume, against all evidence, that new federal infrastructure spending would on the margin be more productive than private investment?

    And, not to put too fine a point on it, this type of federal spending is basically a pay off to labor unions through the mechanisms of the Davis Bacon act which requires federal contractors to pay the prevailing wage (read union wage) on these projects. The effect is to give large union shops an inherent advantage over smaller rivals because it raises their costs. Background information on Davis-Bacon is available at this link at the Institute for Justice:

    So as is usual with Krugman, there are lost of assertions, lots of rants, lots of straw men knocked over, but not a lot by way of facts and reasoned analysis.
