Robert Merton was eight years old when he began his entrepreneurial activities. He created the fictitious RCM Savings of Dollars and Cents Company and collected money from family and friends. Two years later, he bought his first share of stocks. He was a special kid. It鈥檚 no surprise, he went on to become one of the most influential researchers in financial economics, expanding the Black-Scholes formula, which contributed to the rapid development of new financial products and more efficient risk management. Today, he emphasizes how financial markets have made our society better off and argues that we need to reestablish trust in the financial services industry.

Getting lucky

As a PhD student in applied mathematics at Caltech, Merton would get to the local brokerage house every morning at 6:30 am for the opening of the New York stock exchange. Before he鈥檇 even written his thesis, he realized that things needed to change and applied to MIT. How did he get into graduate school without ever having taken an economics course? "You know, I have a favorite phrase,鈥 he says with a smile. 鈥淚t鈥檚 always better to be lucky than smart."

Managing risk efficiently

In the early 1970s, he鈥檇 leave his mark in the field by contributing to a pioneering formula for the valuation of stock options. In general, options give the right, but not the obligation, to buy or sell a financial asset in the future at an agreed-upon price. "They give you flexibility, and flexibility is the greatest value when you have uncertainty," Merton explains. But to allow for an appropriate level of risk in market transactions, options have to be correctly valued, which was exactly the problem Merton was working on, as were his colleagues Myron Scholes and Fischer Black, the namesakes of the original model.

"At some point, Myron told me the basic idea they had. My first reaction was that can鈥檛 be right." Merton took his colleagues鈥 notes home. "I came back from the weekend and said, 鈥業 think you鈥檙e right, but it鈥檚 much more general than you know.鈥" Merton had realized how far-reaching the formula really was and that it could be applied to other financial instruments, such as mortgages and student loans.

"It was a production theory,鈥 he continues. 鈥淗ow we produce all the financial products out there, how we price them, how we figure out their risks." The methodology became widely used by traders and investors. It also laid the foundation for a much broader and more rapid development of derivatives markets. "You could take something you鈥檇 never seen before and you now had a way to attack it," Merton says.

Do derivatives threaten the stability of financial markets?

Merton knows that some people think the high number of derivative products today might be superfluous, if not dangerous.

Have derivatives made us safer? That鈥檚 not the right question to ask. The question is have they made us better off? Yes, they have.

"People say all you need is a simple system,鈥 he says. 鈥淭hey鈥檝e never been out in the world because that isn鈥檛 true. You need these tools. Because of them we can run systems much more efficiently and effectively."

There may be financial instruments suitable for sophisticated investors only but to Merton, that鈥檚 not a good argument against innovation. "If I have someone who says this is too complicated for me to understand, I鈥檇 say 鈥業f doing this is useful to society, you have two choices. Either you try to understand it, or you find someone who can.鈥"

Is there any way of stopping financial crises?

Merton emphasizes how the financial crisis of 2008 didn鈥檛 take place in any "exotic" part of the market, but rather the most regulated one. "The mortgage market was 30 odd years old, it was the only way you could do it and still is the only way,鈥 he says. 鈥淲hat doesn鈥檛 hold up to any data is the idea that innovation was the cause of it all."

What the financial sector needs: trust and competence

Merton emphasizes how both trust and competence are indispensable in financial markets where you鈥檙e likely to face risky situations and where some services, active investing for example, can only be made transparent to a certain degree. "What to put your money in, how much to invest, how often to trade, those decisions are inherently judgmental, therefore inherently opaque."

How can we regain trust in the financial sector?

"I want to find a good surgeon but I want it to be transparent,鈥 he begins, drawing a comparison. 鈥淪o my surgeon says, 鈥極k, Mr. Merton, here are all the scientific studies, here鈥檚 a list of every tool in the operating room.鈥 Complete transparency. Except it鈥檚 not transparent to me. I can鈥檛 tell how risky this is, whether this person鈥檚 going to do a good job. My choice is, I find a doctor I trust."

That鈥檚 why Merton feels creating trust should be a strategic consideration. "If you can create trust, you can create a huge amount of value," he says. A possible strategy in the financial sector is fee-only advisors. "Whatever you pay me, that鈥檚 the only money I get. No commissions, no gifts or vacations, not a toothpick. That鈥檚 a business model.鈥

He knows that there are ways to institutionalize trust, both in the government and in the private sector. "I think to get out of the crisis, that鈥檚 something we need to do because until we reestablish trust, we鈥檒l never have a solution," he says.

Fintech - a threat to traditional institutions?

The huge technological developments of our time have had an impact on the financial services industry too. As a result of new financial technology, also known as fintech, companies, processes and products are changing. "Processing is something that Silicon Valley is very good at,鈥 says Merton. 鈥淏ut financial services? They talk about computers that will do it for you. Would you do this with your medicine? You wouldn鈥檛 take your meds from someone you didn鈥檛 know, even if it was delivered to you on your cellphone, very efficiently, 24/7, with the push of a button."

Will Silicon Valley take over the financial sector?

He explains how there鈥檚 an important difference between medical and financial advice or other tools. "I know after 10 minutes it鈥檚 a lousy movie,鈥 he says. 鈥淚 don鈥檛 know someone has given me bad financial advice until it鈥檚 too late. That鈥檚 why fintech will not displace financial advisors on its own."

Providing for your own retirement

The father of three knows times are changing fast. As a professor of finance at MIT, he not only keeps a close eye on financial developments but on his students too, and he has advice to share when it comes to retirement savings. "If you鈥檝e got the benefit of living longer than your parents, and you want the same standard of living, you鈥檝e got to work longer," he says. But that doesn鈥檛 mean young people should worry too much. "They need to understand that there are limits like that. And that there are a lot of good ways that we can do better at saving for retirement."

Why should young people provide for their retirement?

Merton thinks that young people should welcome financial innovations and use it for their benefit. That鈥檚 why it鈥檚 so important to him that people working in financial services are competent and trustworthy. "You shouldn鈥檛 have to get an education to try to figure out how to manage your portfolio,鈥 he says. 鈥淵ou should be educated to find someone to trust to do that."

There鈥檚 no free lunch. If it looks too good to be true, it probably isn鈥檛 true. If you learn that, you may miss out on occasional opportunities, but you stay out of an awful lot of trouble.
