They don’t agree:
Question 1 — Agree
Economists in Sapienza and Zingales’ study resolutely agreed that it is hard to predict stock prices. A majority of the public agreed with the statement, but not so resolutely. Stock prices are the culmination of transactions between humans, and human behaviour is hard to predict because it is often irrational and informed by cognitive fallacies.
Question 2 — Agree, with a bitter taste in my mouth.
Economists were vastly more bullish on the stimulus’ effect on unemployment than the general public. And the data is actually quite unkind toward the economists’ view — the real unemployment path was far worse than the path projected by those in the Obama administration who promoted the stimulus. However, this is more of a symptom of the stimulus’ designers underestimating the depth of the economic contraction that the financial crisis caused. There is no doubt that the stimulus created jobs and lowered the unemployment rate in the immediate term. Whether the jobs created were really useful and beneficial — and to what extent the stimulus was a malinvestment of capital — is another question entirely, and one which can only be answered in the long run.
Question 3 — Agree
Economists overwhelmingly agreed that market factors are the chief cause behind variation in petrol prices. The public agreed, but to a lesser extent. Presumably, the dissenting public and dissenting economists see government intervention as a more significant force? Certainly, the present global oil market is a precarious pyramid of supply chains balanced on the back of the petrodollar empire. But the market reflects these factors. When governments start a war, that is reflected in the oil price. That’s a force that the market responds to. If a central planner was directly setting the oil price (rather than merely influencing it) — as is the case in communist countries — that would be a price determined by non-market forces.
Question 4 — Uncertain
Economists were broadly certain that a carbon tax is less costly than mileage standards. I think this is far too general a question. Without nuts-and-bolts policy proposals, it is not really possible to assess which would be more costly.
Question 5 — Uncertain, leaning toward Disagree.
This was the only question where economists and the public were largely agreeable — and economists were largely split. As I stated above, the “success” of the stimulus package can only really be assessed in the longer run, and even then there are difficulties with measurement. Generally, I suspect very much that the various interventions in 2008 onward have preserved and supported economically unsustainable and inefficient sectors and industries that ought to have been liquidated and rebuilt (especially the financial industry, but also other sectors, e.g. Detroit). Had the government in 2008 followed the liquidationary trend in the market, the slump would have been much deeper, unemployment would have risen much higher, but the eventual rebound may have been much quicker and stronger.
Question 6 — Agree
This is where economists and the public disagree the most. It is the point on which the public was the most bullish, and economists almost unanimously bearish. Economists in general seem to believe that what they define as free trade is best, even when it destroys domestic supply chains and drastically decreases manufacturing employment. To economists, this means that the American government should not discriminate against foreign products but buy for the best product and the best price. This ignores some important externalities. Buying American certainly supports American jobs, because money goes to American companies, and toward American salaries. This might foster inefficient and otherwise-unsustainable industries, but if the American public chooses to favour American products for their government, that is their right. And a strong domestic manufacturing base is no bad thing, either.
