\r
\n" ); document.write( "\n" ); document.write( "Supply Function indicates the relationship between the \"quantity\" of the
\n" ); document.write( "commodity supplied and the \"unit\"\"+price\" of the commodity.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " The \"slope\" of a supply curve is \"usually\"\"+positive\", as price
\n" ); document.write( "increases, quantity supplied increases and vice-versa.\r
\n" ); document.write( "\n" ); document.write( "The \"y-intercept\" of the supply curve (0,b) represents the \"lowest\"
\n" ); document.write( "\"price\" at which an item will be supplied. \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Normally, we put the good’s own price and cost into the supply function.\r
\n" ); document.write( "\n" ); document.write( "For the previous example that we use, \r
\n" ); document.write( "\n" ); document.write( "Qs=g(p, wage, capital cost)\r
\n" ); document.write( "\n" ); document.write( "When p increases, firms/producers want to produce more goods because it will provide them with more profit. When cost increase, produce would like to reduce their supply given same capital constraint. \r
\n" ); document.write( "\n" ); document.write( "So,
\n" ); document.write( "P increases ...=>... Quantity supplied increases along the supply curve.
\n" ); document.write( "Wage increases (cost increases) -=>-- supply curve shift to the left for same price.\r
\n" ); document.write( "\n" ); document.write( "An example of supply function:\r
\n" ); document.write( "\n" ); document.write( "Qs=178+40p-20w-60r\r
\n" ); document.write( "\n" ); document.write( "where \"w=wage\" of labor, \"r=interest_+rate\" for producer’s loan\r
\n" ); document.write( "\n" ); document.write( "When \"w=5.5\" and \"+r=1.05\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"Qs=178%2B40p-2%2A5.5-60%2A1.05\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "=\"104%2B40p\"\r
\n" ); document.write( "\n" ); document.write( "Suppose \"w=10\", then \r
\n" ); document.write( "\n" ); document.write( "\"Qs=178%2B40p-2%2A8-60%2A1.05\"\r
\n" ); document.write( "\n" ); document.write( "=\"99%2B40p\"\r
\n" ); document.write( "\n" ); document.write( "So when \"wage\"\"+rises\", supply curve \"shifts\" to the \"left\", which means that for a given price, producers will supply \"less\" goods than before.\r
\n" ); document.write( "
