James, are you including the money itself as a good when you say that value requires a desire for goods? Money certainly has value, even if only as a means of exchange.
I think you are right to focus on what destroys value. You also make the interesting point that destruction of the value in one context may increase the value of other goods. I will deal with these points together, because I think that identifying what is “destroying value” will show that the value is not displaced. Only_Humean, I think this will be relevant to your points as well, and I will tie it in explicitly where appropriate. I’ll start with another example.
Instead of talking about books or consumer goods, look at some more basic resource like gas (‘petrol’ in the queen’s english). I hope it’s beyond argument that if we pour the gas on the ground, society has lost something (note that this does not require accounting of environmental effects or anything like that; for a stupid illustration, we might have used that gas to power a tractor to harvest crops, and we get more from the crops than we do from the gasoline-soaked earth). But what about in a situation where we aren’t simply pouring out the gas, we’re deciding between using it to harvest crops, or using it to power a light bulb. How do we decide this? In a market economy, the decision is made by who is willing to pay more. If harvesting crops produces more value, then someone looking to use the gas to run a tractor will be willing to pay more for the gas. If powering a light bulb produces X value, and powering a tractor produces Y > X, the gas will sell at a price Z such that X < Z < Y. But if gas purchased at Z is then used for powering a lightbulb, society yet again loses something. We’ve established that powering a light bulb only will only get us X value, and we put in Z value.
To see that this is a net loss, replace the [easier] dollar values with some other basic resource, like person-hours. Let’s say it takes T person hours to harvest a unit of crops without gas, S person hours to produce gas, and R person hours to harvest a unit of crops with gas, and that these values are further constrained by the relation S + R < T (that is to say, it takes fewer hours to produce gas and use it to harvest crops than it does to harvest crops without gas). Producing gas, then, saves us person hours when we use it to harvest crops.
Now, the easy case is where powering a lightbulb for a unit of time costs less in person hours than does producing gas and using the gas to power the lightbulb. In that case, it’s clear that using gas to power the lightbulb results in a net loss of person-hours. A slightly harder case is where using gas to power a lightbulb is more efficient (i.e. uses fewer person-hours than does powering a lightbulb without gas), but not as much more efficient as harvesting a unit of crops with the same amount of gas. If we use the gas to power a lightbulb, we lose the difference in person-hour gains between the lightbulb use and the harvesting use of that gas. Society loses those person hours. As a result, the person-hours spent producing the gas are worth less to society; part of their value is destroyed.
To say that value is destroyed is then just to say that society is made worse off. Whenever resources are wasted, society is made worse off. That’s true whether the waste is complete or partial. The situation doesn’t change when we’re talking about exchanging money for resources rather than resources for resources, because the money is just an abstraction of the value of resources. If I can sell my person-hours for money and use the money to buy gas, it doesn’t matter if I’m selling my person hours to someone who will use them for gas production or website administration, I can still use them to buy gas.
OH, that ‘harder’ example is where I think your book example falls. If you spend money (or resources) on a book thinking that you will get more value from the book than the value of the money you’re spending, it actually does destroy value when you end up getting less. Someone has spent person-hours creating that book, and when you buy it you reimburse her for her time. If the book is shitty, you are reimbursing her for wasted resources, and encouraging her to waste more hours creating shitty books. Since you are more likley to misappraise the goodness of a book to someone than that person is himself, you are more likely to waste value by gifting a book than by giving the person the money that you would have spent on the book. That higher probability is a greater risk of waste, so the value extracted from the good has to be reduced by the increased risk of that good being wasted. Thus, like when you use gas to power a lightbulb rather than to harvest crops, you waste, and destroy value, when you give gifts because of the difference in likelihood that the gift will not be of sufficient value. (Your other comments go to social bonding and similar effects of gifting, which I think I adequately respond to in the OP; please let me know if I’ve misunderstood).
Books are an interesting and noteworthy example on which to drill down, since they are non-rivalrous, and because the ‘value’ you’re extracting from them is pleasant leisure:
-
The non-rivalrousness means that the price is a little fuzzier than when you’re talking about a good where each instance of the good can be readily mapped to the resources that go into it. Because each copy of the book costs only a small amount once the writing is complete, there’s less loss when someone who doesn’t like the book ends up with it. With rivalrous goods like a shirt, the fact that I have the shirt (or the gas or the person-hour) means that it can’t be had by anyone else. It can be more readily wasted by misallocation than can a non-rivalrous good. There is still waste with the non-rivalrous good to the extent that each copy of the good has a price (which some intellectual property skeptics would challenge anyway).
-
The fact that the value you’re extracting is pleasure means that you’re essentially seeking social waste anyway. But presumably you value your leisure time, it somehow does something for you, and so to spend that on a book that you dislike is to waste that resource, and perhaps you’ll need to spend more leisure time on another book in order to compensate (or you’ll just be grumpier when you return to your socially-productive tasks, still a cost).
So, it seems like in this thread we’ve identified some classes of gifts that maybe we can agree are better than others in terms of their social effects (again, ignoring the positive effects of social bonding etc. that come from the gift-giving event):
- Used goods, especially goods that one owns but no longer values.
- Non-rivalrous goods. This need not be limited to intellectual property; a gym mebership similarly tends not to waste resources in the same way.
- Sentimental gifts.
- Gifts that the recipient could not buy if given the cash spent on them (e.g. gifts from travel, gifts sold in limited number or for a limited time, gifts only sold to certain people).
- Best of all, cash, because it lets the recipient allocate it optimally and minimizes the likelihood of mistakes.
