  Can It Be Prevented This Time?

  Lorenzo Esposito and Giuseppe Mastromatteo
  Abstract

  Since the nineties, crises have punctuated financial markets, shattering the conventional wisdom about how these markets work and how to regulate them, and forcing a deep rethinking of the supervisory framework that, however, did not change much of the banks’ behavior and incentives. In particular, banking regulation did not face the nexus profitability-riskiness. Based on Minsky’s financial instability hypothesis, we discuss the literature on banks’ profitability and its relation to the originate-to-distribute model. We also propose a different strategy for banking regulation, based on a profitability cap that prevents financial innovation from overwhelming supervision. Finally, we discuss the data for the US case, confirming the importance of profitability as a signal of incoming troubles and the possibility of using the profitability cap to greatly simplify banking regulation.

  Anatomy of a Stock Market Bubble

  Frank Veneroso
  Abstract

  According to Frank Veneroso, a broad subset of today’s US stock market has become what he calls a “pure price-chasing bubble.” Examination of the history of comparable pure price-chasing bubbles shows there has been a set of key causal factors that contributed to these rare market events. The most extreme such case was an over-the-counter market in Kuwait called the “Souk al-Manakh.” This exemplar of a pure price-chasing phenomenon may shed light—albeit unflattering—on the current US equity market, Veneroso contends.

  The Souk Al-Manakh

  Frank Veneroso and Mark Pasquali
  Abstract

  It is widely agreed that the Nasdaq during the dot-com era 20 years ago was a full-fledged stock market bubble. Recently, the US stock market according to many metrics has become significantly more speculative and overvalued than it was at the dot-com peak 20 years ago. In both instances, a very broad subset of stocks became so highly valued that speculation in them had to be untethered from all fundamentals: the essence of what we call a “pure price-chasing bubble.”
   
  This paper, drawn from a book in progress, examines the history of stock markets for comparable pure price-chasing bubbles, finding nine or so which have ever reached such a speculative extreme, with an over-the-counter market in Kuwait in the early 1980s called the “Souk al-Manakh” representing the most extreme example. Based on personal exposure to this Souk al-Manakh almost 40 years ago, we describe this anatomy and thereby make transparent the recurrent dynamics—on the way up and on the way down—of these greatest asset bubbles in human history. When one applies this framework to the current US stock market, one sees that the stock market in the US today will likely follow the disastrous path of the dot-com market.
