Perhaps the most famous, and over used, economic equation is “money is the root of all evil.” Many on the left will be quick to agree and use it as a way to shun any profit making activity. Those on the right may be quick to fire back with another over used maxim: “greed is good.” Between those two extremes, we have bland corporate claims of creating shareholder wealth and offering customer value. These terms, “value,” “wealth,” or “money” may be used interchangeably but they can mean different things. I would like to propose a way of using them that might make economic discussions clearer, and even answer the question if money really is the root of all evil.
Value: Any immediate increase in well-being. If you enjoy this post, over and above the expense of your time invested, then I have created value. No direct exchange has taken place, and certainly no money has changed hands, but value (I hope) has been created. All of us, in however tiny an amount, are better off. If several readers enjoy it then the total value created is even higher. Sadly is possible to destroy value; should you have receive less benefit from this post than your time invested then I have (and I apologize) destroyed value.
Wealth: A store of actual or potential future well-being. Wealth provides a flow of benefits now and into the future. A house is wealth in that it provides a flow of benefits (shelter) over time. It is the benefits, or well-being, provided that counts as wealth not any money price placed on it.
Any wealth creation begins with value creation. It starts with a search for a way to bring or add value by generating new or changing existing goods, services, or experiences. Google started as a value creating enterprise. Its value creation effort was to make search more effective. If I can provide something for 50 cents that you value at one dollar then I have created wealth. You have one dollar’s worth of value and 50 cents, I have 50 cents that I previously did not. Without this creation you would either have nothing (but kept your dollar) or what you wanted (but without your dollar).
Supporters of capitalism generally assume (or at least point to) the above model. In the simplified example we are both better off. While I receive 50 of your cents, you receive something that you value at one dollar, you still have 50 cents to enjoy elsewhere. We might argue how the benefits of such a transaction be distributed; I could charge 95 cents for the thing you value at one dollar and still create wealth, the distribution is the only difference, we are both still better off. The critics of capitalism, perhaps more realistically, assume (and point to) the money creation example discussed below.
Money: A notional and abstract measure for the accounting of wealth, or a useful medium for exchange. Money creation does not involve value creation; at best it involves wealth distribution, but may actually involve value destruction. Much of the recent financial meltdown was due to attempts to create money absent the creation of value or wealth. Rising asset prices do not create wealth: your house provides the exact same benefits it did when it was half the price. The notional money price offers no benefit while you remain in residence. Many of the exotic financial instruments created little or no value; they did offer the chance to shift wealth from one set of hands to the other. At its base attempts to create money are not attempts to create anything, they are attempts to capture value and re-distribute wealth.
So to return to the opening cliché: It may not be money, or even excess desire for it, but rather attempts to create money that are the root of all evil. Many of these attempts could probably be better described with their more common names: fraud, deceit, rent-seeking, or crookedness.
I will expand upon the price versus wealth idea because it may not be obvious. When you purchase a house, it provides you with a flow of benefits (e.g., shelter). That flow of benefits represents wealth (continued well-being). Regardless of the money price that flow of benefits does not change. If the price doubles the house does not double in size or sprout granite counter tops. When you come to sell you may receive more money than you paid, but will likely have to spend more to receive the same continued benefits from another house (e.g., same number of rooms, equally good neighborhood, etc.) Even trading down does not increase your wealth, it merely changes the distribution of that wealth (less living space but more cash). You may be lucky and move from a high cost location to a lower cost one. This good fortune (for you) does not represent a creation of wealth but a transfer from the new owner to you. The new owners have the same benefits as you did when your purchased at half the price but have paid more for it. No wealth has being created, just transferred. This is the classic money creation outcome. It seems great for you but it is a zero sum game, not everyone can win. I wonder how many retirees who gleefully pocket such windfalls realize that it essentially comes from their children (assuming the children could afford to purchase their childhood home).
The most famous economic equation is more likely Black–Scholes, the pricing model for options that helped start the derivatives revolution. The award for most infamous probably should go to David Li’s Gaussian copula function used to model various debt instruments such as CDOs.
