Non sopravvalutiamo la vita, non sottovalutiamo la libertà

TESI: NON SOPRAVVALUTIAMO LE VITE, NON SOTTOVALUTIAMO LA LIBERTÀ.
IN FONDO UNA VITA E’ CIO’ CHE CONTIENE.

In the face of this irony, what should we do? Can we truly foolproof our surroundings if we so often cause more mischief in doing so? Or should we be ecologists and allow natural systems to take their course? At the end of this journey, I concluded that the answer is neither: we must reconcile the engineers with the ecologists. But how?

IN LODE DELL'AZZARDO.
By providing confidence, moral hazard enables society to do things and take risks that it otherwise wouldn’t, many of which make us better off.

safety is a state of mind, not a statute. You can write laws that tell people their bank can fail, their money market fund may not pay back a dollar per share, their home is not insured if a nearby levee fails, or their uncooked food might carry dangerous pathogens. Yet this won’t change their behavior if their experience tells them that banks never fail, money market funds always pay back a dollar, the levee always holds, and uncooked food never makes them sick.

expunging moral hazard would also expunge confidence and all the beneficial risk taking that confidence enables.

Of course, we cannot endure a crisis and recession that cost the United States from $6 trillion to $14 trillion and do nothing. The question is, what can we do that won’t make matters worse?

IL PREZZO DI UNA VITA UMANA
Though it seems repugnant to put a price on human life, it happens all the time, when juries award damages for negligence resulting in death,

Federal agencies, for example, typically put the value of a statistical life at $9 million. Would you pay $9 million to save your own life (assuming you had $9 million)? Of course you would. Now let me ask the question slightly differently: would you pay $9 to reduce the chance of death by one in one million? Quite possibly not.

Bioethicists refer to the “rule of rescue,” the urge to help those we see are in distress, even when the help might better be devoted to serving a larger, less visible population. The rule of rescue can lead to very bad decisions.

There is another cost that foolproofers must consider when trying to make us safer: our loss of freedom.

We really can limit danger and risk if we are willing to use rules, prohibitions, and jail time. This is one way around the Peltzman effect. If we worry that making an activity safer encourages more risk, ban the activity altogether.

Opponents of seat-belt laws often base their arguments on freedom, not health. Despite overwhelming evidence that they reduce deaths and injuries, mandatory motorcycle helmet laws have been repealed in many states, often in response to litigation branding such laws an infringement on motorcyclists’ liberty and an unconstitutional exercise of police power.

SPAZIO = SPAZIO DI MANOVRA.

As I explored our efforts to create safety, I discovered one remedy that seems to work everywhere: space.

For example, when I asked Adrian Lund of the Insurance Institute for Highway Safety why aviation has had more success reducing accidents than automobiles have, his answer surprised me: “In aviation … it’s an easier problem to deal with.

The financial and economic worlds have their equivalent of space: it’s called capital. This is essentially the cushion of shareholder capital that is available to absorb losses.

Capital has, correctly, become the central tool in regulators’ drive to reinforce the financial system against another crisis.

ALTRO PRESERVATIVO: PUNTARE SULLA MEMORIA.
That leads us to the final lesson of how to foolproof ourselves. As we have seen throughout this book, we often seek safety in response to fear, and fear is rooted in experience. The experience of crisis or disaster makes survivors more conscientious and risk averse. Houses built immediately after a hurricane are less likely to suffer damage in the next one....

Moreover, experience is of limited help when disasters are rare. “One can be a particularly poor driver and never become involved in an auto accident,” note Donald MacGregor and Paul Slovic.

A country can change its attitude toward risk just as a company can. Canada drew praise in the wake of the global financial crisis for the fact that none of its banks failed or needed bailouts; indeed, they emerged stronger than they had been, an important reason Canada’s recession was much milder than that of the United States. This is often attributed to culture: the stereotype is that Canadians are more risk averse, less swashbuckling than Americans. There’s some truth to this.
Note: UN ESEMPIO: LA CRISI FINANZIARIA IN CANADA Edit
Yet the different experiences during the crisis are not all due to culture. Canadians are as susceptible to bubbles, fraudsters, and charlatans as Americans. Two small Canadian banks collapsed during the 1980s, and a crippling real estate depression laid many banks low in the early 1990s. Importantly, this left an imprint on both bankers and regulators... The Canadian government absorbed the lessons of the 1980s and 1990s as well. It created an independent regulator that steadily pushed banks to raise their capital sooner than its foreign competitors did...

The right tradeoff between risk and stability will maximize the units of innovation we get per unit of instability. It has taken us a century to learn that trying to put out every fire is a recipe for bigger, deadlier fires. The solution is not to let all fires burn, but to make it possible for small fires to burn without hurting people so that we save our resources for the big fires.
