From the Federal Reserve Bank of New York's Liberty Street Economics blog:
You might hear: “Economy eschmonomy.” Another possibility is: “Economy 
schmeconomy.” This phenomenon of repeating a word with the prefix shm- 
(or sometimes “schm-”), is called shm-reduplication. It challenges the 
relevance and sometimes the value of the repeated word, and examples can
 be found in articles like this Newsday clip “The High End: Economy, shmeconomy — the rich still travel.” 
Who cares about whether it’s eschmonomy or schmeconomy? A pair of linguists from MIT and Harvard, that’s who. This 2003 paper
 describes the authors’ attempt to understand how the shm-reduplication 
works (the linguistic rules that govern its use) and how the researchers
 used interviews and questionnaires to investigate those rules. The 
authors also review the Yiddish origins of this usage (there are 
competing theories), provide a short section on the meaning of phrases 
that use the reduplication, and inform us that there is a relative lack 
of study of this form of reduplication (there are a few other forms).
Who loves shm-reduplication? The media; print, online, broadcast . . . 
you name it. It’s a very compact linguistic device. A simple two-word 
phrase can convey a wealth of information about the author (or speaker),
 the audience, the object of the shm-reduplication, and the overall 
situation.  “Economy eschmonomy” could mean the opposite of “it’s the 
economy, stupid” — phrased differently: Never mind about the economy, 
this other thing (aliens from outer space, for example) is much more 
important. Or it could be a more personal statement: Forget about the 
economy, I’m going on a vacation (this comes up in an example below).  
Some illustrative examples of shm-reduplication on the web:
Currency shmurrency
 In Barron’s, columnist Alan Abelson says: “For even if Beijing were to 
up the value of the yuan by as much a 15% … it wouldn't get our 
somnolent factories up and smoking again. The reason is simply that what
 our manufacturing workers earn in an hour, their counterparts in China 
earn in a week. Currency, shmurrency, no matter how hard and how smart 
our folks work, that gap is as ugly and daunting as it is yawning.”
