Economics for Dummies #1: Agriculture Starts it Off

Yanis Varoufakis explains how the economy operates in a conversational style, as if he were explaining/discussing it with his 16 yo daughter. Hence the title of the book is: Talking to My Daughter About the Economy.

 

A true economy, he says, needs a surplus:

“Surplus is the extra bit that allows for accumulation and future use.”

He points out that a hunter gatherer society cannot produce surpluses, only an agricultural one can. Why is that? Because hunter gatherer items like fish, rabbits and bananas rot quickly and thus cannot be preserved. Whereas agricultural outputs (corn, rice etc) can be stored for long periods.

 

Once surpluses became possible with the advent of agriculture, it set us of on the path to other things that changed mankind forever. Let us elaborate on that. Once enough people have surplus produce, it is efficient to build common granaries. That in turn creates the need for a mechanism to keep records – who stored how much – and thus written records came into existence. These written records often performed the same role as currency – one could swap one’s record of grains stored for some other good or service.

 

Now that there was something valuable being stored (grains), one needed to protect it. Over time, specialized roles (soldiers) began to evolve for just that purpose. Surplus made that possible. How? Since people were producing more than they needed, others could take on new roles! As the setup grew in size and complexity (farmers, granary managers, soldiers), the need for rulers and administrators came up.

 

The rulers soon began to exercise their power to do something they have been doing ever since – “print” money. Rulers could issue records of grain amounts that hadn’t yet been produced and use that to buy things and services. What did they intend to back this newly “minted” currency with? By taking a fraction of the future produce from the farmers – taxes had started.

 

But why would people be willing to use a record that didn’t correspond to any actual grains, just the hope of grains in future? Because they had “faith” that the ruler (state) would come good later – the idea of “debt” had started. Plus, the ruler/state had the power to enforce the acceptability of this currency across the realm – this was (and continues to be) key to any currency.

 

The large unit of people in such a setup now made it possible to create the first “technologies” – from ploughs to irrigation systems. In turn, those inventions set off a cascading effect for related discoveries and inventions.

 

Interesting how the switch to agriculture set off so many other changes that continue to this day.

Student of the Year

As a toddler, my daughter loved Alia Bhatt’s songs, esp. the ones from Student of the Year . (That movie did have many good songs and well-choreographed dances). Fast forward to present day, when she is 12 yo. She rarely watches Hindi movies now, but one of the few ones she likes of late, Raja aur Rani ki Prem Kahani has, yes, Alia Bhatt.   If I had any hopes that there was anything to be read in the name of her toddler-time favorite ( Student of the Year ), they have been dashed. Our conversations come exam time are perfectly captured by this photo and its caption: In fact, the pic below captures how she and I look at her answer sheets – me intently, she with an expression of “It’s over, so why are you even looking at it?”   Of late, we pull her leg and tell her that she isn’t showing any signs of academic prowess, she’d better find a rich guy to marry. Some time later, she showed us this meme on the Internet: “Me No Study, Me No Care Me Go Marry Millionaire If He Die

The Retort of the "Luxury Person"

Image
Coming up with biting and witty retorts. It’s something we dream of, but rarely manage to pull off. Worse, the more we stew over the offending remark, the more likely we are to come up with that dream retort, as Calvin ruefully points out: During our last holiday at the Taj Resort, seeing my wife carrying towels to our poolside chairs, one of the kids there mistook her for a member of the staff and asked for a towel. When my wife narrated this to us, I did not imagine that my 8 yo daughter would come up with her own retort. But a day later, my daughter recapped the incident, an incident that didn’t even involve her in the first place , and said, “You know what I’d have told that kid who asked for the towel?”. And without waiting for an answer, she told us anyway: “I don’t work here. I too am a luxury person who is living at this resort. Go get your own towel.” We were highly amused by the phrase she had coined: “luxury person”. It certainly captures the kind of holid

Animal Senses #7: Touch and Remote Touch

Instinctively, we think touch is based on contact. Not entirely true, explains Ed Yong in Immense World – there’s a more important aspect than contact: “These incredible feats are possible through movement. If you rest a fingertip upon a surface, you can get only a limited idea of its features. But as soon you’re allowed to move, everything changes. Hardness becomes apparent with a press. Textures resolve at a stroke.” As you run your fingers over a surface, they hit the tiny peaks and troughs and set off vibrations in the mechanoreceptors at their tips.   At the tip of its snout, the star-nosed mole has many pairs of hairless appendages. It uses them to touch things around itself. Alive or dead? Food or ignore? It does these movements at an insane speed. In the time it takes to blink our eyes, the star-nosed mole can probe, identify and swallow its food. “Light may be the fastest thing in the universe, but light sensors have their limits, and the star-nosed mole’s sense of
