Cryptocurrencies, Tariffs, “Too Big to Fail,” and Other Top LSE Posts of 2018
“Cryptocurrency” hit the cultural mainstream in 2018. In March, Merriam-Webster added “cryptocurrency” to the dictionary, and in what was perhaps a greater litmus test of pop culture recognition, “bitcoin” was added to the official Scrabble dictionary in September. With such a surge in interest, it’s not too surprising that the most viewed post on Liberty Street Economics this past year focused on an issue surrounding how digital currencies operate that is not often put in the spotlight—trust. Similarly, as the subject of tariffs has become a more frequent topic of discussion in the news, readers have sought additional info, which fueled interest in another of our most viewed posts of the year. As 2019 approaches, we offer a chance to revisit these posts and the rest of our top five of 2018.
Changing Risk‑Return Profiles
Are stock returns predictable? This question is a perennially popular subject of debate. In this post, we highlight some results from our recent working paper, where we investigate the matter. Rather than focusing on a single object like the forecasted mean or median, we look at the entire distribution of stock returns and find that the realized volatility of stock returns, especially financial sector stock returns, has strong predictive content for the future distribution of stock returns. This is a robust feature of the data since all of our results are obtained with real-time analyses using stock return data since the 1920s. Motivated by this result, we then evaluate whether the banking system appears healthier today, and if recent regulatory reforms have helped.
Regulatory Changes and the Cost of Capital for Banks
In response to the financial crisis nearly a decade ago, a number of regulations were passed to improve the safety and soundness of the financial system. In this post and our related staff report, we provide a new perspective on the effect of these regulations by estimating the cost of capital for banks over the past two decades. We find that, while banks’ cost of capital soared during the financial crisis, after the passage of the Dodd-Frank Act (DFA), banks experienced a greater decrease in their cost of capital than nonbanks and nonbank financial intermediaries (NBFI).
