A few months ago, a friend in the entertainment industry told me of a new business model in Hollywood: hoarding videotapes. Apparently, the earthquake in Japan knocked offline a Sony factory that makes certain types of tape. That factory was also in the tsunami zone, so now there's a serious tape shortage threatening the television industry. The NBA scrambled to get enough tap
e to broadcast the NBA finals; one executive told the Hollywood Reporter
, "It's like a bank run."
In the last few years, economists have spent a lot of time and energy thinking about bank runs. A bank run happens when depositors think a bank is weak and scramble to get their money out before it collapses. "Tight coupling" of financial institutions, like when banks are overly dependent on each other, can create a cascading series of problems for the system itself. We saw this with Lehman Brothers when it went bankrupt. Its AAA-rated debt instruments lost value unexpectedly; that caused money market funds that held those presumably safe bonds to suddenly lose value. A shadow bank run was the result, as investors rushed to withdraw from the money market funds.
Worryingly, there's been very little consideration of how systemic collapses can happen in another, perhaps more dangerous realm - the industrial supply system that keeps us in everything from medicine to food to cars to, yes, videotape. In 2004, for instance, England closed
one single factory, which caused the United States to lose half of its flu vaccine supply.
Barry Lynn of the New America Foundation has been studying industrial supply shocks since 1999, when he noticed that global computer chip production was concentrated in Taiwan. After a severe earthquake in that country, the global computer industry nearly shut down, crashing the stocks of large computer makers. This level of concentration of the production of key components in a globalized economy is a new phenomenon. Lynn's work points to the highly dangerous side of globalization, the flip side of a hyper-efficient global supply chain. When one link in that chain is broken, there is no fallback.
