For example, if there is an increase in the demand for pizza, then there will be greater demand for all the resources that are involved in the production of pizza, including cheese, sauce, dough, and workers. Resource demand can also change when the price of a product changes. For example, if the price of pizza decreases, then the worker who is trained to make a pizza generates a smaller MRP (because MRP = MP x price), so the demand for these workers will decrease.</p><h3 id="f8ae8d49-d5b0-4046-9c52-bc9f75f5519b" class="">Productivity of the Resource</h3><p id="0fd549b5-63bb-473d-a2b9-1474cf3609de" class="">A change in productivity can also cause a shift in demand in the factor market. Let's take a situation where a new technique is developed that cuts production time in half. Since labor productivity has increased, each worker can make a greater quantity of the goods than they used to. This leads to each worker generating a greater marginal revenue product which increases their value to the firm or business. As a result, this increases the demand for labor.</p><h3 id="e6256dbd-6d7d-44d4-a677-ed0e1cf67207" class="">Price of Related Inputs</h3><p id="b747b605-b78b-471a-8caf-262d8d25e507" class="">A change in the price of related inputs can also shift the demand in the factor market. In this determinant, we are referring to substitute resources and complementary resources that are used in the production of goods and services. If the price of one resource becomes more expensive, the firm will increase their demand for the substitute resource. For example, if the price of copper piping increases, home builders will more willing to demand plastic piping. In looking at complementary resources, we can look at the production of soft drinks. Both aluminum and sugar are used in the production of soft drinks. If the price of aluminum increases, then we would see the demand for sugar decrease since both products are used to produce soft drinks.</p><h3 id="6085ca88-dde9-4a42-9110-ba3d2d748082" class="">Graphing Change in Factor Demand</h3><figure id="380038c6-0a9d-4b4a-aa2d-d45f1e781d84" class="image"><a href="Unit%205%20Factor%20Markets%200b3c331dbc9340d48b0c736f2c58243e/Untitled.png"><img style="width:1226px" src="Unit%205%20Factor%20Markets%200b3c331dbc9340d48b0c736f2c58243e/Untitled.png"/></a></figure><figure id="be40cc3e-5b21-4966-980e-2c2479d97c98" class="image"><a href="Unit%205%20Factor%20Markets%200b3c331dbc9340d48b0c736f2c58243e/Untitled%201.png"><img style="width:1178px" src="Unit%205%20Factor%20Markets%200b3c331dbc9340d48b0c736f2c58243e/Untitled%201.png"/></a></figure><h2 id="f0fff0b7-a00e-483e-8c44-f9b4e409eb07" class="">Factor Supply</h2><p id="f1e48a3d-953f-45cb-a6d5-6d25ac37cf06" class="">Just like with the demand for resources, there are several things that can change the supply of resources.
