When discussing the supply and demand for a good or service, it is appropriate for households to be on the demand side and firms to be on the supply side, but the opposite is true when modeling the supply and demand for labor or another factor of production. In general, the circular-flow model is useful because it informs the creation of the supply and demand model. Topics covered include statistics and probability for simulation, techniques for sensitivity estimation, goal-seeking and optimization. This site provides a web-enhanced course on computer systems modelling and simulation, providing modelling tools for simulating complex man-made systems. (For example, an income tax could be represented by a government entity being inserted between households and factor markets, and a tax on a producer could be represented by inserting government between firms and goods and services markets.) The purpose of this page is to provide resources in the rapidly growing area computer simulation. On the other hand, the amount of content specifically for Revit is overwhelming, and there are some cool features, like being able to comment on models and start conversations with other users. It’s interesting to note that there are four places where the government could be inserted into the model, and each point of intervention is realistic for some markets and not for others. is similar to the SketchUp 3D Warehouse, in that the content is user-generated, and therefore the quality can be hit or miss. One could, however, extend this model to incorporate government intervention by inserting government between the households, firms, and markets. This model is simplified in a number of ways, most notably in that it represents a purely capitalistic economy with no role for government. In the other side of the exchange, firms provide money to households as compensation for the use of factors of production, and this is represented by the direction of the arrows on the “SSSS” lines that connect to the “Factor Markets” box. Households provide labor, capital, and other factors of production to firms, and this is represented by the direction of the arrows on the “Labor, capital, land, etc.” lines on the diagram above. (Technically, employees can more accurately be thought of as being rented rather than being sold, but this is usually an unnecessary distinction.) Therefore, the functions of households and firms are reversed in factor markets as compared to in goods and services markets.

supply) labor to firms, they can be thought of as the sellers of their time or work product. In factor markets, households and firms play different roles than they do in the markets for goods and services. Labor markets are the most commonly discussed form of a factor market, but it’s important to remember that factors of production can take many forms. Some examples of factors of production are labor (the work was done by people), capital (the machines used to makes products), land, and so on. The term “factors of production” refers to anything that is used by a firm in order to make a final product.

Luckily, the goods and services markets don’t tell the whole story, and factor markets serve to complete the circular flow of money and resources. If markets for goods and services were the only markets available, firms would eventually have all of the money in an economy, households would have all of the finished products, and economic activity would stop.
