"I try to go to the wine store with a wine list but what does one do when none of the items are on the list."
A useful trick a friend taught me for buying non-US wines in the US is to pay attention to the importer. For example, when buying a Spanish wine, looking for Jorge Ordonez on the back label is often a big win.
"Why pay foreigners when American wines are just as good."
A few reasons:
1. If I'm shopping for wine, and I don't see any producers I'm familiar with, I have a good tool for picking likely winners for imported wines: looking at the importer. I don't have a similar trick for domestic wines. Hints welcome!
2. Wines from different parts of the world can have pretty distinct characteristics, and I find it fun to try different things.
3. I've generally (though not always) had better luck finding cheap-and-good foreign wines than American wines.
4. I think there can be very good reasons to buy locally, but I also think a stronger global economy will have great benefits and I have no problem contributing to it.
On the East Coast, it's often cheaper and more environmentally friendly to buy imported French and Spanish wines rather than trucking them from CA. (I forget the study, my apologies.)
On the other hand, if you're just being patriotic, go right ahead.
It used to be "Two Buck Chuck" on the east coast, but then they raised the price to $2.99 (=~ $3) - hence the "Three Buck Chuck". Is it still $1.99 in California?
It's doubtful that Giffen goods exist at all, but wine is a beautiful example of a Veblen good; demand actually strengthens rather than recedes as the price increases.
A bit off-topic, but there was a study recently claiming Giffen behaviour in China concerning rice staples. The classic textbook case of the Irish potato famine was always difficult (if not impossible) to prove, but this is apparently some evidence of the existence of Giffen goods.
I wouldn't go as far as saying the demand function has a negative slope during most of its domain, but it may have small segments with a negative slope.
But I totally agree with you, the evidence here shows that the wine market is ridiculous.
That text should be mandatory reading in schools, both for young children and adolescents, and followed up with critical discussion.
