Money as layers

Source Whenever I try to come up with a metaphor for the monetary and banking system I think about the 2010 film Inception , one of my favorite films. After falling into a dream state, the protagonists sedate themselves within the dream so that they can move to an even deeper dream level, and so on; a dream piled on a dream piled on a dream piled on a dream. Conversely, by setting up a series of "kicks," the protagonists progressively wake themselves up from each dream level until they eventually reemerge back in reality.  Like Inception , our monetary system is a layer upon a layer upon a layer. Anyone who withdraws cash at an ATM is 'kicking' back into the underlying central bank layer from the banking layer; depositing cash is like sedating oneself back into the overlying banking layer. Monetary history a story of how these layers have evolved over time. The original bottom layer was comprised of gold and silver coins. On top this base, banks erected the banknote l

Demonetization by serial number

This continues a series of posts ( 1 , 2 , 3 ) I've been writing that tries to improve on Indian PM Narendra Modi's clumsy demonetization, or what I prefer to call a policy of surprise note swaps. The main goal of Modi's demonetization (i.e. note swapping) is to attack holdings of so-called "black money," or unaccounted cash. The problem here is that to have a genuine long-run effect on the behavior of illicit cash users, a policy of demonetization needs to be more than a one-off game. It needs to be a repeatable one. A credible threat of a repeat swap a few months down the road ensures that stocks of licit money don't get rebuilt after the most recent swap. If that threat isn't credible, then people will simply go back to old patterns of cash usage. It's worth pointing out that the idea of behind demonetization precedes Modi by many decades.

To what extent can Trump trash the dollar?

Donald Trump doesn't like the strong dollar, but is there anything he can do about it? Last month Donald Trump told the Wall Street Journal that American companies can’t compete "because our currency is too strong. And it’s killing us...” Trump's dislike of the strong dollar doesn't surprise me. I've known a few mercantilists over the years, and all of them have always been keen on trashing their home currency, the idea being that with a weaker currency domestic manufacturers will enjoy a shot to the arm. This in turn stems from the antiquated (and very wrong) idea that manufacturing is somehow the most important activity an economy can be engaged in. Tweeting about one's desire for a weak dollar is one thing, but are there any actual levers Trump can pull on to affect the exchange rate? U.S. exchange rate interventions are rare these days, with only two occurring in the last twenty years. In September 2000 U.S. monetary authorities intervened with other centr
