Parallel Currencies and Dollarized Nations

When we visited Maldives a couple of years ago, we realized the US dollar is accepted as legal tender everywhere. Even though the country has its own currency, the Maldivian Rufiyaa. In her book, The Almighty Dollar, Dharshini David says there’s a name for this: “parallel currency”.

 

One can see why tiny, tourist’y nations like Maldives would accept the dollar (it saves tourists the hassle and costs of conversions). Or why a country like Panama (think of all the fees in the Panama Canal) would do the same. But the dollar is also the parallel currency in countries where the local folks have no faith in their economy and/or government. Like Russia when the USSR collapsed. The same reason applies in several Latin American countries and Cambodia even today. Of course, a parallel currency also makes corruption and black money even more easy: transactions in the parallel currency never show up in the country’s financial systems.

 

And then there are countries that have eliminated their own currencies and replaced it officially with the US dollar! Like Ecuador and El Salvador. Why would countries “dollarize”? For one, if their trade is overwhelmingly with the US, you can see the benefits of avoiding all those conversion costs and fluctuating exchange rates. Another reason is that it inspires confidence in foreign investors: they don’t have to worry about the currency being devalued.

 

But of course, “dollarizing” comes at a cost. Those countries can’t print money, should the need arise. If you don’t see why that’s a problem, just look back at the problems the PIGS (Portugal, Italy, Greece and Spain) ran into during the 2008 financial crisis. They couldn’t deploy the usual tool in such crisis: printing money. Why not? Because the Euro wasn’t their currency alone. The Germans refused, and the PIGS were stuck…

 

In addition, a country that has its own currency can raise and reduce interest rates based on its needs. Not so if you are dollarized: the US government sets the rates based on what’s good for the US, and you’d have no say in it.

 

And finally, American law allows the US to prosecute any transaction anywhere in the world that “touches” the US. By definition, the dollar, no matter where it is used in the world, “touches” the US since that is where it originated. And so, any corruption involving use of the dollar, technically, entitles the US to prosecute! Remember the FIFA corruption scandal a few years back? I’d always wondered why the prosecution for that originated in the US, a country that doesn’t even care about football. The answer from this book? Because most of the kickbacks were in dollars…

 

The book doesn’t talk of it, but I wonder what happens to all the dollars outside the US (and half of all those dollars are outside the US at any point) ever “demonetizes” old notes, say, ones without certain anti-forgery features?

Why we Deceive Ourselves

In their book, The Elephant in the Brain , the authors describe this weird aspect of deception that we practice: deceiving ourselves! That is so weird: “If our minds contain maps of our worlds, what good comes from having an inaccurate version of these maps?” The Sigmund Freud school of thought treats self-deception as a defense mechanism, “a way for the ego to protect itself”. The mind seeks to protect itself from anxiety and other negative emotions. Many object to this reasoning: since accurate information is so critical to our survival, surely distorting information would be dangerous. Wouldn’t the goal of protecting our self-esteem have been better achieved by making the brain’s self-esteem mechanism stronger instead? The new school of thought explains self-deception as “primarily outward-facing, manipulative, and ultimately self-serving”. This is based on Thomas Schelling’s work on game theory: “In a variety of scenarios, limiting or sabotaging yourself is the winn...

Europe #3 - Innsbruck

The last city we visited in Europe was Innsbruck in the Austrian Alps. After the cold and windy experience (at times) of Paris and Netherlands, Innsbruck was a wonderful change – it didn’t feel that cold, it was not windy all of which made it easy to walk around. Something absolutely necessary given how scenic the place is.   Since the hotel check-in time was much later in the day, we left the baggage and went to the Swarovski HQ-cum-museum about an hour by bus from Innsbruck. The crystal exhibits were brilliant – colorful, bright, shiny. Jewellery aside, it was a display of what one can do with crystals. While my wife and daughter loved the jewellery, I liked the superhero themed exhibits of Batman, Spiderman, the Hulk, and Star Wars. We didn’t buy anything there, though we did buy stuff in the Swarovski store in Innsbruck – jewellery, not the superhero stuff.   Innsbruck is a major tourist attraction during the skiing season but now in summer, we saw many groups of ...

The Thrill of the Chase

So many people complain about the difficulty in making decisions while shopping. Do you buy Brand X that gives 20% extra free? Or Brand Y that has 10% off? Or Brand Z that gives something else free with it? Do you buy that flat screen TV today or wait for the sale at Diwali? Now since the customer is king, shouldn’t companies be simplifying pricing choices? Like maybe offering consistently low prices all the time? Not so fast, as the US store, JC Penney discovered to its cost. Turns out that while people do complain about pricing choices, they are irrational. Also, they enjoy the thrill of the chase. Huh? The word “sale” acts like a siren call for many people: it lures them in to make that purchase. Consistently low prices don’t do the same. Besides, if a competitor lowers their prices just one time of the year, and Poof! Suddenly that low price claim becomes suspect in shoppers’ eyes. Then there are those sites that offer coupons: have lunch at Restaurant A on Wedne...
