Having looked at Aggregate Demand, we now introduce Aggregate Supply which gets a bit complicated with two different schools of thought, and we also need to refer to three possible different equilibrium situations (at full employment, the deflationary (or recessionary) gap and the inflationary gap). Equilibria is simply the plural of equilibrium. <\/font><\/p>\n<p><font size=\"3\">Here are the syllabus requirements:<\/font><\/p>\n<blockquote>\n<p><font size=\"3\">\u2022 Aggregate supply<\/font><\/p>\n<p><font size=\"3\">a) short-run<\/font><\/p>\n<p><font size=\"3\">b) long-run (Keynesian versus neo-classical approach)<\/font><\/p>\n<p><font size=\"3\">\u2022 Full employment level of national income<\/font><\/p>\n<p><font size=\"3\">\u2022 Equilibrium level of national income<\/font><\/p>\n<p><font size=\"3\">\u2022 Inflationary gap<\/font><\/p>\n<p><font size=\"3\">\u2022 Deflationary gap<\/font><\/p>\n<\/blockquote>\n<p><font size=\"3\">Make sure you can define each of these as well as explain them.<\/font><\/p>\n<p><font size=\"3\">To recap on inflationary and recessionary (deflationary) gaps, refer to this video by <b><a href=\"http:\/\/www.youtube.com\/user\/ACDCLeadership\"><strong>ACDCLeadership<\/strong><\/a> <\/b>but <b>note<\/b> that it explains it from a neo-classical perspective. He then goes on to explore fiscal and monetary policy responses, which we will explore in more detail later, but is worth watching now.<\/font><\/p>\n<p><iframe loading=\"lazy\" height=\"360\" src=\"http:\/\/www.youtube.com\/embed\/9B-gIfhnyeo?rel=0\" frameborder=\"0\" width=\"480\" allowfullscreen=\"allowfullscreen\"><\/iframe><\/p>\n<h3><font size=\"3\">A quick and very useful summary of some of the key differences is given by <\/font><a href=\"http:\/\/www.youtube.com\/user\/ACDCLeadership\"><strong><font size=\"3\">ACDCLeadership<\/font><\/strong><\/a><font size=\"3\"> in his video Classical vs. Keynesian Aggregate Supply- Macroeconomics. <\/font><font size=\"3\">He is delivering this to an AP audience (as opposed to IB). Notice that he combines Keynesian, Intermediate and Classical ranges into what we can simply think of as the Keynesian AS curve.<\/font><\/h3>\n<h3><font size=\"3\"><\/font><\/h3>\n<h3><iframe loading=\"lazy\" height=\"360\" src=\"http:\/\/www.youtube.com\/embed\/HGjtcPssfCs?rel=0\" frameborder=\"0\" width=\"480\" allowfullscreen=\"allowfullscreen\"><\/iframe><\/h3>\n<h3><font size=\"3\"><\/font><\/h3>\n<p><font size=\"3\">This next clip could also help understanding already reached in class \/ revised through the text book.<\/font><\/p>\n<h3><a href=\"http:\/\/www.youtube.com\/user\/pajholden\"><strong><font size=\"3\">pajholden<\/font><\/strong><\/a><font size=\"3\"> on <\/font><a href=\"http:\/\/www.youtube.com\/watch?v=QG56sFoNNa8\"><font size=\"3\">Keynesian Vs Monetarist on the LRAS curve<\/font><\/a><\/h3>\n<p><font size=\"3\">He refers to those holding the neo-classical perspective as \u2018monetarists\u2019. Good for understanding how the market for labour is understood under each perspective. Notice the simplified (original) Keynesian AS curve which he starts off with for the Keynesian perspective.<\/font><\/p>\n<p><a href=\"http:\/\/www.youtube.com\/watch?v=QG56sFoNNa8\"><font size=\"3\">http:\/\/www.youtube.com\/watch?v=QG56sFoNNa8<\/font><\/a><\/p>\n<h3><a href=\"http:\/\/www.youtube.com\/user\/BrynJonesOnline\"><strong><font size=\"3\">BrynJonesOnline<\/font><\/strong><\/a><font size=\"3\"> on <\/font><a href=\"http:\/\/www.youtube.com\/watch?v=RemyT7upOMI\"><font size=\"3\">Aggregate Demand &amp; Aggregate Supply<\/font><\/a><\/h3>\n<h3><font size=\"3\">Notice that his AS curve is very similar to the Keynesian version. So he assumes a Keynesian perspective (without saying it), and it is good for showing the three different phases \/ segments along it. Note that at 2 minutes 10 seconds, he is now mentioning supply side bottle necks (again without actually saying it). For now, you do not need to view any further from 2 minutes 45 onwards (after the interlude) as he now moves on to AS changes &#8211; (a) increased costs and (b) successful supply side policy which we explore later.<\/font><\/h3>\n<p><iframe loading=\"lazy\" height=\"315\" src=\"http:\/\/www.youtube.com\/embed\/RemyT7upOMI?rel=0\" frameborder=\"0\" width=\"560\" allowfullscreen=\"allowfullscreen\"><\/iframe><\/p>\n<p><font size=\"3\">From <\/font><a href=\"http:\/\/reffonomics.com,\"><font size=\"3\">http:\/\/reffonomics.com,<\/font><\/a><font size=\"3\"> this slideshow also combines the Keynesian and neoclassical perspectives on to one graph whereas we have preferred to keep them separate. However, this is very good for getting the history of thought behind these two perspectives, including the name of influential economists, and for seeing the simple differences between the Keynesian and Neo-classical view of AS. Note also that they put Yfe (Full employment level of national income \u2013 what they say is 97%)) at the vertical segment whereas some text books prefer to think of that as the maximum level of employment (100%).<\/font><\/p>\n<p><font size=\"3\">Click here: <\/font><a href=\"http:\/\/www.reffonomics.com\/textbook2\/macroeconomics2\/aggregatesupply\/aggregatesupplyranges.swf\"><font size=\"3\">Aggregate Supply Ranges<\/font><\/a><\/p>\n<p><font size=\"3\">Finally, from the same website, this slideshow is excellent for summarising where we are and indicating where we are headed next with possible government policies<\/font><\/p>\n<p><a href=\"http:\/\/www.reffonomics.com\/TRB\/chapter30\/Macro10.swf\"><font size=\"3\">Macroeconomics Graphs<\/font><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>This title refers to a lot of theory which it is worth having explained to you first by a teacher of Economics.
