The Eurozone

With the Greek and Irish bailouts, there always seems to be a whispering about the stability of the Eurozone.


My question for today is what makes the United States different from the Eurozone?


One suggestion offered in the article that piqued my interest in the topic (here) offers the suggestion that federal transfer taxes keep America more homogeneous. In fact, when you look at the data, there is absolutely no correlation between per capita taxes paid to the government vs per capita expenditures received. However, there is a strong negative correlation between income per capita and the ratio of taxes paid vs expenditures received.


While I'm not sure that is the whole picture, it is certain that the US is more homogeneous.


Here is a listing of Eurozone countries by GDP per capita:

	Population	Nominal GDP	GDP/capita
Luxembourg	491,702	52,449	106668
Ireland	4,517,758	227,193	50289
Netherlands	16,481,139	792,128	48063
Austria	8,356,707	384,908	46060
Finland	5,325,115	237,512	44602
Belgium	10,741,048	468,522	43620
Germany	82,062,249	3,346,702	40782
Italy	60,090,430	2,112,780	35160
France	64,105,125	2,112,780	32958
Spain	45,853,045	1,460,250	31846
Cyprus	801,622	24,910	31074
Greece	11,262,539	329,924	29294
Slovenia	2,053,393	48,477	23608
Portugal	10,631,800	227,676	21415
Malta	412,614	7,449	18053
Slovakia	5,411,062	87,642	16197
Eurozone	328,597,348	12,455,979	37907

Look at that range! The US states range only from Connecticut at 54,397 to Mississippi at 30,103. 


This same divergence is seen in debt to GDP ratios. In the Eurozone, Debt to GDP ranges from 115% for Italy to 14% for Luxembourg. These countries likely differ in their reliance on imports and exports as well. State debt to GDP ratios are all below 20%, although that is because the federal government takes on much of the debt. However, this makes state defaults far less severe because the federal government can bail them out and it is simply a smaller dollar amount.


The Eurozone got this way through centuries of different economic climate and policy. Meanwhile, the US has generally had the same climate and policies throughout the states throughout its history. While all the US states probably need similar treatment, it may be that the eurozone is just too heterogeneous for one currency.
