Consider a rental market with an equilibrium of $600\/month. If the government wishes to decrease this price to make it more affordable for renters, it may place a binding\u00a0<strong>price ceiling\u00a0<\/strong>of $400\/month. This policy means the landlords cannot charge more than $400 per month. What will this do to our equilibrium? Refer to Figure 4.5a. Whereas before 300 homes were rented, there is now a housing shortage. At the lower price of $400\/month, quantity supplied is only 200 housing units and a quantity demanded is 400 housing units. This means that 200 renters who want to rent can no longer find homes! \u00a0This is important, because when quantity demanded and quantity supplied are unequal,\u00a0<span style=\"text-decoration: underline;\">the market is restrained by the lower value.<\/span>\r\n\r\nDespite this information, it is not enough to tell us if the market is more or less efficient \u2013 our metric for that is\u00a0market surplus.\u00a0Even though some renters cannot find homes, the government still successfully lowered the price for some consumers. So how do these effects weigh out?\r\n<div class=\"textbox shaded\">\r\n\r\n[caption id=\"attachment_2008\" align=\"aligncenter\" width=\"638\"]<img src=\"https:\/\/pressbooks.bccampus.ca\/uvicecon103\/wp-content\/uploads\/sites\/58\/2016\/11\/4129267310_2ed2e45fc7_o.jpg\" alt=\"\" class=\"wp-image-2008 size-full\" width=\"638\" height=\"411\" \/> (Credit: Manoel Lemos\/ Flickr\/ CC BY-SA 2.0)[\/caption]\r\n<h3 style=\"text-align: center;\">Save Us R2-D2, You're Our Only Hope!<\/h3>\r\nIf the equilibrium price is $6 and the government says you cannot charge more than $8, the government intervention is meaningless or 'non-binding'. Whereas price ceiling aims to lower the price, price floors aim to raise it. Since this seems backwards, it is easy to get confused about when price ceilings and price floors are binding.\u00a0Rather than memorizing which is which, consider an example from Star Wars to help remember.\r\n\r\nIn the original Star Wars, Luke, Leia, Han Solo, and Chewbacca are trapped in a garbage disposal that begins to collapse inwards. The room becomes more constrained as the walls come together. If you were in a room, what would cause you to feel constrained? If the ceiling is rising you have more space, so it is not constraining. Similarly, if the floor falls, you have more room. If the <span style=\"text-decoration: underline;\">ceiling starts falling<\/span>, or the <span style=\"text-decoration: underline;\">floor begins to rise<\/span> then you are constrained. This helps us remember an important principle:\r\n\r\n<strong>Only a price floor above equilibrium or a price ceiling below equilibrium is binding.<\/strong>\r\n\r\n<\/div>\r\n<h2><strong>Calculating Market Surplus<\/strong><\/h2>\r\nTo find out the impact of government's price ceiling, we must calculate market surplus before, and after a policy. This method will be an important gauge for all our policy analysis in this topic. Consider Figure 4.5b, where the effects of the Price Ceiling is shown.\r\n\r\n[caption id=\"attachment_814\" align=\"aligncenter\" width=\"766\"]<img src=\"https:\/\/pressbooks.bccampus.ca\/uvicecon103\/wp-content\/uploads\/sites\/58\/2016\/11\/Figure-4.6b.jpg\" alt=\"figure-4-6b\" class=\"wp-image-814\" width=\"766\" height=\"346\" \/> Figure 4.5b[\/caption]\r\n<h3><strong>Before<\/strong><\/h3>\r\nThe\u00a0calculation of market surplus before policy intervention should be straight forward by now. Market surplus is equal to the sum of consumer surplus and producer surplus, calculating from Figure 4.5b:\r\n\r\n<strong>Consumer Surplus<\/strong>\u00a0(Blue Area): [(1200-600) x 300]\/2 = $90,000\r\n\r\n<strong>Producer Surplus<\/strong>\u00a0(Red Area): [(600) x 300]\/2 = $90,000\r\n\r\n<strong>Market Surplus<\/strong>: $180,000\r\n<h3><strong>After<\/strong><\/h3>\r\nThe\u00a0calculation of market surplus after intervention is less obvious. Consumers have lost surplus in some areas, but gained surplus in others (we will look at this closely in the next Figure 4.5c). Producers have lost surplus.\r\n\r\n<strong>Consumer Surplus<\/strong>\u00a0(Blue Area): [(1200-800) x 200]\/2] + (400\u00d7200) = $120,000\r\n\r\n<strong>Producer Surplus<\/strong>\u00a0(Red Area): [(600) x 300]\/2 = $40,000\r\n\r\n<strong>Market Surplus<\/strong>: $160,000\r\n\r\nLooking before and after we see that producer surplus has decreased and consumer surplus increased \u2013 but the decrease in producer surplus outweighed the effects of the increase in consumer surplus, causing deadweight loss<strong>.\u00a0<\/strong>This means that the market is less efficient, because by removing the regulation, the market as a whole is better off.\r\n<h2><strong>What About Redistribution?<\/strong><\/h2>\r\nIt\u2019s easy to look at the total numbers and show that market surplus has decreased, but how does this change affect individual consumers and firms?\r\n\r\nIn Figure 4.5c the areas which change as a result of the policy are shown.\r\n\r\n[caption id=\"attachment_818\" align=\"aligncenter\" width=\"426\"]<img src=\"https:\/\/pressbooks.bccampus.ca\/uvicecon103\/wp-content\/uploads\/sites\/58\/2016\/11\/Figure-4.6d.jpg\" alt=\"figure-4-6d\" class=\"wp-image-818\" width=\"426\" height=\"355\" \/> Figure 4.5c[\/caption]\r\n<h3><strong>Consumers<\/strong><\/h3>\r\nConsumers gain an area of A and lose an area of B.\r\n<h4><strong>Surplus Decrease \u2013 Area B<\/strong><\/h4>\r\nAs mentioned previously, the quantity supplied in the market decreases from 300 rental units to 200. This means that 100 renters can no longer find homes. We can assume that the consumers who are willing to pay most for the homes will end up with the rental units (they will start looking earlier, exploring more options etc.) so consumers on the demand curve WTP between $800 and $600 will be cut out of the market. This results in a $10,000 loss in consumer surplus, shown in Figure 4.5c as area B.\r\n<h4><strong>Surplus Increase \u2013 Area A<\/strong><\/h4>\r\nAlternatively, the 200 consumers who are able to find homes now go from paying $600\/month to paying $400\/month, resulting in a $40,000 increase in consumer surplus. This is shown in Figure 4.5c as area A.\r\n\r\nOverall, consumers gain $30,000, which is consistent with the calculations above.\r\n<h3><strong>Producers:<\/strong><\/h3>\r\nProducers lose areas C and A\r\n<h4><strong>Surplus Decrease \u2013 Area C<\/strong><\/h4>\r\nThe price ceiling causes the landlords to reconsider staying in the rental market, as fewer landlords can make a profit with the lower price. This causes 100 landlords to leave the market, reducing their producer surplus to nothing. This forgone surplus amounts to $10,000 and is represented in Figure 4.5c as area C.\r\n<h4><strong>Surplus Decrease \u2013 Area A<\/strong><\/h4>\r\nLike consumers, some producers will remain in the market, but these producers now have to face the reality of lower rent revenue. Each of the 200 landlords loses $200 of revenue. This results in a $40,000 decrease, represented as area A.\r\n\r\nOverall, producers lose $50,000, which is consistent with the calculations above.\r\n<h2><strong>Transfer and Deadweight Loss:<\/strong><\/h2>\r\ndWe can summarize the overall effects in the market as two categories: a transfer of surplus and a deadweight loss.\r\n<h3><strong>Transfer<\/strong><\/h3>\r\nNotice that Area A was a transfer from the landlords to the renters who remain in the market. 200 renters now save $200 each, and 200 landlords now lose $200 each. It is important to recognize that this transfer is a result of the\u00a0<strong>price effect\u00a0<\/strong>of the policy, meaning it occurred because price differed from equilibrium.\r\n<h3><strong>DWL<\/strong><\/h3>\r\nAlternatively, the deadweight loss results because there are players who are no longer able to be a part of the market. 100 renters and 100 landlords all lose a varied amount based on their willingness to pay and marginal costs. This change is a result of the\u00a0<strong>quantity effect\u00a0<\/strong>on the policy,\u00a0<span>meaning it occurred because quantity\u00a0differed from equilibrium.<\/span>\r\n\r\n<strong>A change in quantity from the equilibrium value is the only thing that causes a DWL. Changes in price will cause transfers. While the two effects work together, it is important to be able to distinguish between the two.<\/strong>\r\n\r\nThis was a fairly lengthy explanation of price ceilings, but it is one that will lead into the discussion of all policy. Every policy we will look at in microeconomics has both a quantity effect and a price effect, and it is important to understand how the policy impacts individual market players.\r\n<h1><strong>Price\u00a0Floor<\/strong><\/h1>\r\nWhile the price floor has a very similar analysis to the price ceiling, it is important to look at it separately. A common example of a price floor is a minimum wage policy. The labor market is unique in that the workers are the producers of labor and the firms are consumers of labor. Price can be denominated in hourly wage, with the quantity of workers on the x-axis. If the government sets a binding minimum wage (price floor), it must be set above the equilibrium price.\r\n\r\n[caption id=\"attachment_824\" align=\"alignnone\" width=\"523\"]<img src=\"https:\/\/pressbooks.bccampus.ca\/uvicecon103\/wp-content\/uploads\/sites\/58\/2016\/11\/Labour-Market-w-Price-floor.jpg\" alt=\"labour-market-w-price-floor\" class=\"wp-image-824\" width=\"523\" height=\"412\" \/> Figure 4.5d[\/caption]\r\n\r\nIn Figure 4.5d, the equilibrium wage is shown as $10\/hour. This is where the demand for labor is equal to the number of workers who want to find jobs. At this level there is no unemployment. However, if the government sets a minimum wage of $13\/hour, this will change. The <span style=\"text-decoration: underline;\">Quantity of Labor Supplied<\/span> (workers looking for jobs) will be 400, but the quantity demanded will be 200. This means that 200 workers will be unemployed! Again, this is not enough information to determine whether the market is inefficient \u2013 we have to calculate the change in market surplus!\r\n\r\n[caption id=\"attachment_825\" align=\"alignnone\" width=\"736\"]<img src=\"https:\/\/pressbooks.bccampus.ca\/uvicecon103\/wp-content\/uploads\/sites\/58\/2016\/11\/Labour-Market-Price-Floor-Surplus.jpg\" alt=\"labour-market-price-floor-surplus\" class=\"wp-image-825\" width=\"736\" height=\"341\" \/> Figure 4.5e[\/caption]\r\n\r\nUsing the same process as before:\r\n<h2><strong>Before<\/strong><\/h2>\r\n<strong>Consumer Surplus<\/strong> (Blue Area): [(20-10) x 300]\/2 = $1500\r\n\r\n<strong>Producer Surplus<\/strong> (Red Area): [(10) x 300]\/2 = $1500\r\n\r\n<strong>Market Surplus<\/strong>: $3000\r\n<h2><strong>After<\/strong><\/h2>\r\n<strong>Consumer Surplus<\/strong> (Blue Area): [(20-13) x 200]\/2= $700\r\n\r\n<strong>Producer Surplus<\/strong> (Red Area): [(13-7) x 200] + (7 x 200)\/2 = $1900\r\n\r\n<strong>Market Surplus<\/strong>: $2600\r\n\r\nSince the market surplus after the policy is less than the market surplus before, there is a deadweight loss!\r\n\r\n<img src=\"https:\/\/pressbooks.bccampus.ca\/uvicecon103\/wp-content\/uploads\/sites\/58\/2016\/11\/Screen-Shot-2017-02-18-at-6.47.57-PM.png\" class=\"alignnone wp-image-1562 size-full\" width=\"403\" height=\"333\" \/>\r\n\r\nAgain, the changes in the market can be categorized as a transfer and a deadweight loss. This time, the transfer is from consumers (firms) to producers (workers), since the workers who are able to find work are better off. This causes no change\u00a0to market surplus in isolation but is coupled with the deadweight loss caused by workers who are no longer able to find jobs as firms leave the market.\r\n<h2><strong>Summary<\/strong><\/h2>\r\nIn the absence of externalities, both the price floor and price ceiling cause deadweight loss, since they change the market quantity from what would occur in equilibrium. This is accompanied by a transfer of surplus from one player to another. If the goal of the policy is to reduce quantity to a certain level, both a price ceiling or a price floor could be used to achieve this aim. In this case, both policies would result in the same size DWL. The distribution of surplus will be very different, but the change in quantity away from equilibrium is the only variable that matters when calculating DWL. As we will see, if a tax, quota, or any other policy causes the same change in quantity as another, the deadweight loss will be the same.\r\n<div class=\"textbox\">\r\n<h2>Glossary<\/h2>\r\n<dl id=\"fs-idm31045488\" class=\"definition\">\r\n \t<dt><strong>Price Ceiling<\/strong><\/dt>\r\n \t<dd id=\"fs-idm97401792\"><em>a legal maximum price<\/em><\/dd>\r\n<\/dl>\r\n<dl id=\"fs-idm33170736\" class=\"definition\">\r\n \t<dt><strong>Price Control<\/strong><\/dt>\r\n \t<dd id=\"fs-idp6837056\"><em>government laws to regulate prices instead of letting market forces determine prices<\/em><\/dd>\r\n<\/dl>\r\n<dl id=\"fs-idp96167168\" class=\"definition\">\r\n \t<dt><\/dt>\r\n \t<dt><strong>Price\u00a0Effect<\/strong><\/dt>\r\n \t<dd id=\"fs-idp6837056\"><em>the impact when price\u00a0differs from equilibrium, causes a transfer of surplus between\u00a0parties<\/em><\/dd>\r\n<\/dl>\r\n<dl id=\"fs-idp96167168\" class=\"definition\">\r\n \t<dt><\/dt>\r\n \t<dt><strong>Price Floor<\/strong><\/dt>\r\n \t<dd id=\"fs-idp6837056\"><em>a legal minimum price<\/em><\/dd>\r\n<\/dl>\r\n<dl class=\"definition\">\r\n \t<dt><\/dt>\r\n \t<dt><strong>Quantity\u00a0Effect<\/strong><\/dt>\r\n \t<dd id=\"fs-idp6837056\"><em>the impact when quantity differs from equilibrium, causes a deadweight loss to society<\/em><\/dd>\r\n<\/dl>\r\n<\/div>\r\n<div class=\"bcc-box bcc-info\">\r\n<h3 itemprop=\"educationalUse\">Exercises 4.5<\/h3>\r\nThe following TWO questions refer to the supply and demand curves illustrated below.\r\n\r\n<img src=\"https:\/\/pressbooks.bccampus.ca\/uvicecon103\/wp-content\/uploads\/sites\/58\/2016\/11\/Screen-Shot-2017-01-22-at-9.09.28-PM.png\" alt=\"\" class=\"alignnone size-full wp-image-1138\" width=\"273\" height=\"215\" \/>\r\n\r\n<strong>1.<\/strong> A price ceiling of P3 causes:\r\n\r\na) A deadweight loss triangle whose corners are ABC.\r\nb) A deadweight loss triangle whose corners are ACD.\r\nc) A deadweight loss triangle whose corners are BEC.\r\nd) A deadweight loss triangle whose corners are CDE.\r\n\r\n&nbsp;\r\n\r\n<strong>2.<\/strong> A price floor of P1 causes:\r\n\r\na) Excess demand equal to the distance AB.\r\nb) Excess supply equal to the distance AB.\r\nc) Excess supply equal to the distance DE.\r\nd) Excess demand equal to the distance DE.\r\n\r\n&nbsp;\r\n\r\n<strong>3.<\/strong> Which of the following statements about price ceilings is TRUE?

So how do these effects weigh out?<\/p>\n<div class=\"textbox shaded\">\n<figure id=\"attachment_2008\" aria-describedby=\"caption-attachment-2008\" style=\"width: 638px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/pressbooks.bccampus.ca\/uvicecon103\/wp-content\/uploads\/sites\/58\/2016\/11\/4129267310_2ed2e45fc7_o.jpg\" alt=\"\" class=\"wp-image-2008 size-full\" width=\"638\" height=\"411\" srcset=\"https:\/\/pressbooks.bccampus.ca\/uvicecon103\/wp-content\/uploads\/sites\/58\/2016\/11\/4129267310_2ed2e45fc7_o.jpg 638w, https:\/\/pressbooks.bccampus.ca\/uvicecon103\/wp-content\/uploads\/sites\/58\/2016\/11\/4129267310_2ed2e45fc7_o-300x193.jpg 300w, https:\/\/pressbooks.bccampus.ca\/uvicecon103\/wp-content\/uploads\/sites\/58\/2016\/11\/4129267310_2ed2e45fc7_o-65x42.jpg 65w, https:\/\/pressbooks.bccampus.ca\/uvicecon103\/wp-content\/uploads\/sites\/58\/2016\/11\/4129267310_2ed2e45fc7_o-225x145.jpg 225w, https:\/\/pressbooks.bccampus.ca\/uvicecon103\/wp-content\/uploads\/sites\/58\/2016\/11\/4129267310_2ed2e45fc7_o-350x225.jpg 350w\" sizes=\"auto, (max-width: 638px) 100vw, 638px\" \/><figcaption id=\"caption-attachment-2008\" class=\"wp-caption-text\">(Credit: Manoel Lemos\/ Flickr\/ CC BY-SA 2.0)<\/figcaption><\/figure>\n<h3 style=\"text-align: center;\">Save Us R2-D2, You&#8217;re Our Only Hope!<\/h3>\n<p>If the equilibrium price is $6 and the government says you cannot charge more than $8, the government intervention is meaningless or &#8216;non-binding&#8217;. Whereas price ceiling aims to lower the price, price floors aim to raise it. Since this seems backwards, it is easy to get confused about when price ceilings and price floors are binding.\u00a0Rather than memorizing which is which, consider an example from Star Wars to help remember.<\/p>\n<p>In the original Star Wars, Luke, Leia, Han Solo, and Chewbacca are trapped in a garbage disposal that begins to collapse inwards. The room becomes more constrained as the walls come together. If you were in a room, what would cause you to feel constrained? If the ceiling is rising you have more space, so it is not constraining. Similarly, if the floor falls, you have more room. If the <span style=\"text-decoration: underline;\">ceiling starts falling<\/span>, or the <span style=\"text-decoration: underline;\">floor begins to rise<\/span> then you are constrained. This helps us remember an important principle:<\/p>\n<p><strong>Only a price floor above equilibrium or a price ceiling below equilibrium is binding.<\/strong><\/p>\n<\/div>\n<h2><strong>Calculating Market Surplus<\/strong><\/h2>\n<p>To find out the impact of government&#8217;s price ceiling, we must calculate market surplus before, and after a policy.

This means that 100 renters can no longer find homes. We can assume that the consumers who are willing to pay most for the homes will end up with the rental units (they will start looking earlier, exploring more options etc.) so consumers on the demand curve WTP between $800 and $600 will be cut out of the market. This results in a $10,000 loss in consumer surplus, shown in Figure 4.5c as area B.<\/p>\n<h4><strong>Surplus Increase \u2013 Area A<\/strong><\/h4>\n<p>Alternatively, the 200 consumers who are able to find homes now go from paying $600\/month to paying $400\/month, resulting in a $40,000 increase in consumer surplus. This is shown in Figure 4.5c as area A.<\/p>\n<p>Overall, consumers gain $30,000, which is consistent with the calculations above.<\/p>\n<h3><strong>Producers:<\/strong><\/h3>\n<p>Producers lose areas C and A<\/p>\n<h4><strong>Surplus Decrease \u2013 Area C<\/strong><\/h4>\n<p>The price ceiling causes the landlords to reconsider staying in the rental market, as fewer landlords can make a profit with the lower price. This causes 100 landlords to leave the market, reducing their producer surplus to nothing. This forgone surplus amounts to $10,000 and is represented in Figure 4.5c as area C.<\/p>\n<h4><strong>Surplus Decrease \u2013 Area A<\/strong><\/h4>\n<p>Like consumers, some producers will remain in the market, but these producers now have to face the reality of lower rent revenue. Each of the 200 landlords loses $200 of revenue. This results in a $40,000 decrease, represented as area A.<\/p>\n<p>Overall, producers lose $50,000, which is consistent with the calculations above.<\/p>\n<h2><strong>Transfer and Deadweight Loss:<\/strong><\/h2>\n<p>dWe can summarize the overall effects in the market as two categories: a transfer of surplus and a deadweight loss.<\/p>\n<h3><strong>Transfer<\/strong><\/h3>\n<p>Notice that Area A was a transfer from the landlords to the renters who remain in the market. 200 renters now save $200 each, and 200 landlords now lose $200 each. It is important to recognize that this transfer is a result of the\u00a0<strong>price effect\u00a0<\/strong>of the policy, meaning it occurred because price differed from equilibrium.<\/p>\n<h3><strong>DWL<\/strong><\/h3>\n<p>Alternatively, the deadweight loss results because there are players who are no longer able to be a part of the market. 100 renters and 100 landlords all lose a varied amount based on their willingness to pay and marginal costs. This change is a result of the\u00a0<strong>quantity effect\u00a0<\/strong>on the policy,\u00a0<span>meaning it occurred because quantity\u00a0differed from equilibrium.<\/span><\/p>\n<p><strong>A change in quantity from the equilibrium value is the only thing that causes a DWL. Changes in price will cause transfers. While the two effects work together, it is important to be able to distinguish between the two.<\/strong><\/p>\n<p>This was a fairly lengthy explanation of price ceilings, but it is one that will lead into the discussion of all policy. Every policy we will look at in microeconomics has both a quantity effect and a price effect, and it is important to understand how the policy impacts individual market players.<\/p>\n<h1><strong>Price\u00a0Floor<\/strong><\/h1>\n<p>While the price floor has a very similar analysis to the price ceiling, it is important to look at it separately. A common example of a price floor is a minimum wage policy. The labor market is unique in that the workers are the producers of labor and the firms are consumers of labor. Price can be denominated in hourly wage, with the quantity of workers on the x-axis. If the government sets a binding minimum wage (price floor), it must be set above the equilibrium price.<\/p>\n<figure id=\"attachment_824\" aria-describedby=\"caption-attachment-824\" style=\"width: 523px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/pressbooks.bccampus.ca\/uvicecon103\/wp-content\/uploads\/sites\/58\/2016\/11\/Labour-Market-w-Price-floor.jpg\" alt=\"labour-market-w-price-floor\" class=\"wp-image-824\" width=\"523\" height=\"412\" srcset=\"https:\/\/pressbooks.bccampus.ca\/uvicecon103\/wp-content\/uploads\/sites\/58\/2016\/11\/Labour-Market-w-Price-floor.jpg 588w, https:\/\/pressbooks.bccampus.ca\/uvicecon103\/wp-content\/uploads\/sites\/58\/2016\/11\/Labour-Market-w-Price-floor-300x236.jpg 300w, https:\/\/pressbooks.bccampus.ca\/uvicecon103\/wp-content\/uploads\/sites\/58\/2016\/11\/Labour-Market-w-Price-floor-65x51.jpg 65w, https:\/\/pressbooks.bccampus.ca\/uvicecon103\/wp-content\/uploads\/sites\/58\/2016\/11\/Labour-Market-w-Price-floor-225x177.jpg 225w, https:\/\/pressbooks.bccampus.ca\/uvicecon103\/wp-content\/uploads\/sites\/58\/2016\/11\/Labour-Market-w-Price-floor-350x276.jpg 350w\" sizes=\"auto, (max-width: 523px) 100vw, 523px\" \/><figcaption id=\"caption-attachment-824\" class=\"wp-caption-text\">Figure 4.5d<\/figcaption><\/figure>\n<p>In Figure 4.5d, the equilibrium wage is shown as $10\/hour.

This time, the transfer is from consumers (firms) to producers (workers), since the workers who are able to find work are better off. This causes no change\u00a0to market surplus in isolation but is coupled with the deadweight loss caused by workers who are no longer able to find jobs as firms leave the market.<\/p>\n<h2><strong>Summary<\/strong><\/h2>\n<p>In the absence of externalities, both the price floor and price ceiling cause deadweight loss, since they change the market quantity from what would occur in equilibrium. This is accompanied by a transfer of surplus from one player to another. If the goal of the policy is to reduce quantity to a certain level, both a price ceiling or a price floor could be used to achieve this aim. In this case, both policies would result in the same size DWL. The distribution of surplus will be very different, but the change in quantity away from equilibrium is the only variable that matters when calculating DWL.
