The military draft, mortality and education

The data sometimes work in mysterious ways and provide puzzling correlations that lead to interesting research questions. One such correlation is that exemption from military service leads to lower mortality later in life.

Piero Cipollone and Alfonso Rosolia find this while looking at a natural experiment following the 1981 earthquake in Southern Italy. Boys from the affected region were exempted from military service, and they were followed, along with non-exempted neighbors, to track their life and education. By concentrating on boys both sides close to the border of the exempt region, they find that those exempt ended up being more educated. I can easily believe that, as they were not spending some of their prime learning years hiding in bushes and peeling potatoes, and they were expecting a longer work life. But the exempt also have lower mortality. This is not due to a lower incidence of military accidents, it is rather linked to the higher school completion rates. In fact, the authors conclude that raising high school completion by 10 percentage points would lower mortality by one or two percentage points in the decade thereafter. That is impressive at that age.

Do Italians trust the television or the judges?

In several countries, mass media have become, at least from my viewpoint, a dominant means of forming public opinion on just about anything. In the US it is particularly apparent that experts are less trusted by the public than media, or even less than people's prejudice. In politics, this is even more widespread, where media make or brake a politician, and politicians cater directly to the media. Imagine how things could turn when the politician owns the media. This is the current situation in Italy, where Prime Minister Silvio Berlusconi heads a formidable media empire and tries to fend off numerous accusations of corruptions and abuse of power (loosely speaking) that emanate from the judiciary.

Fabio Sabatini studies how much the Italian Prime Minister is trusted by the public. He finds that trust in television is by far the cleared determinant for trust in Berlusconi, and the second is lack in education, the third distrust in the judiciary. So much for Berlusconi claiming his empire has nothing to do with his repeated elections.

The demand for theater

What determines demand for theater? Theater managers should be interested in understanding their market. Beyond this, this is also important for policy as theater is frequently and substantially subsidized. This the characteristics of those who go to theater and how frequently they do so may help understand whether it is worth subsidizing it. For example, if only rich people go to theater, one could leave the state out and let the public pay higher prices, which substitute for taxes (and would then improve efficiency). If it is mostly poor people who attend theater, then it may be worth subsidizing if there is some sort of positive externality from it.

Concetta Castiglione uses micro data from Italy to find results that are not very surprising: everything is driven by education and income. Rich educated people pay more taxes and get them back in part in theater performances. This is even more pronounced than for higher education, for which forceful arguments have been made that the state should stop subsidizing it.

Of course, all this ignores consideration about the supply. but that does not matter here. Demand should be essentially the same whether theaters are subsidized or not in Italy.
