Are there any recent discussions? Like Japan's abenomics

@economist Most 'discussions' of that sort are nowdays in blogs. My post was just a tip to encourage you to follow, say, [Krugman](http://krugman.blogs.nytimes.com/2011/10/09/is-lmentary/), who uses IS-LM arguments regulary. Just search for 'krugman blog IS-LM'.

<p>I learnt IS-LM model but I got curious whether it is applicable to the real world. I mean it's just an model, so I doubt that the realtionship between Y and r actually exists. Are there any real life examples that prove the model? I want to know if something like a recent world event or fiscal and monetary policies in sone countries actually affects output and interest rate.</p>

There is a huge discussion about structural Macroeconomics models - especially on their theoretical and practical relevance - with IS-LM being on the forefront of the battle some 40+ years ago. Many people simply reject LM existence. Advanced level textbooks ignore this approach for two decades. However it ironically dominates introductory courses.
  
 Here is a nice [discussion](http://www.bloombergview.com/articles/2014-12-12/krugman-gets-the-big-picture-right) from Bloomberg that claims that, perhaps, the most instructive paper on the matter was published in QJE back in 1992 - [link](http://qje.oxfordjournals.org/content/107/2/709.abstract).
