Taylor’s Part of Podcast Hi everyone! This podcast features Caroline and Taylor (myself) as we will be discussing certain economic topics and looking at how they can apply to real life examples. I will take the first part and Caroline will talk about the second half of our topics. Today we are going to discuss opportunities costs and sunk costs! These are very important things to talk about and acknowledge in the world of economics. Now let's get into what these terms mean, The opportunity cost is the cost of next best alternative use. It is calculated in terms of the other goods. On the other hand, the sunk cost is the money spent on goods or services which cannot be recovered such as paying for rent. While these ideas sound like they may have some similarities, they are actually totally different concepts. First let’s take a look at opportunity cost and dive in a bit further to see how it works. In an example, A person can produce either 50 units of wheat or 100 units of rice by using its all resources in the given season. What is the opportunity cost of 1 unit of wheat? When we are considering this question, we want to determine what we gave up or lost with the production of another good. So in this case, what did we lose in terms of rice by producing 1 unit of wheat? Are we giving up wheat or rice when we use our resources to produce one unit of wheat? The answer is the alternative, which is rice. Therefore, in this case when we produce 1 unit of wheat, our opportunity cost is 2 units of rice. Now that we have a pretty good understanding of opportunity cost, let's look at an example of a sunk cost. Think about whether this statement is true or false: Advertisements are a sunk cost. Before we answer, remember that sunk costs are money that is spent on goods or services that cannot be recovered. This example is sort of tricky because when we think of it in terms of advertising it seems like it is not a sunk cost because of the potential revenue that ads could generate. However, advertisement expenses are considered sunk costs. It is money that once a company or individual spends, they are unable to recover. Before Caroline takes over, I am going to talk about short run average cost and the way that it appears on a graph. When we consider short run costs, we are talking about things that happen in the short term such as parts of the production process and what will occur over a short term output. I have another true or false statement that I want you to consider: The short run average cost is U shaped. (keep in mind this is talking in terms of how it appears on a graph.) The answer to this question is true. The short run average cost is U shaped on a graph because of the law of variable proportion. This law states that while the quantity of one variable factor is changed, the quantities of the other factors remain fixed. This is how we end up with a U like shape on the graph. Podcast Outline 5 Caroline’s Part of Podcast Thanks, Taylor and welcome, again everyone. As Taylor mentioned, we are discussing opportunity cost versus sunk cost today. Sunk cost is the cost that we have already incurred. This cost cannot be recouped as it is already attempted to expend. Whereas opportunity cost is something that a person should take into account. As it is the value of a fog on activity or an alternative when another activity or opportunity is taken. Opportunity cost should have to be measured while making decisions. Let’s look at a couple more scenarios: If we state that the gap between average cost curve and average variable cost curve increases as production increases, but why? We can argue that it is true because the law of variable proportion applies or we could say it is false because the average fixed cost decreases as the production increases. We could even go so far as to say that both are correct or neither are correct. Any thoughts? Well, in this example, the argument that the gap between average cost curve and average variable cost curve increases as production increases is incorrect because the average fixed cost decreases as the production increases. In this next example we state that the average variable cost is minimum when marginal cost is equal to it. Is this the case? Why? We can either say that yes, it is because the marginal cost curve cuts the average cost at its minimum point or yes, it is because the marginal cost is ratio of change in total variable cost and change in output. In this scenario, BOTH are correct. The average variable cost is minimum when marginal cost is equal to it because the marginal cost curve cuts the average cost at its minimum point and also because the marginal cost is ratio of change in total variable cost and change in output. So, to reiterate what we’ve touched on today, the opportunity cost is the cost of next best alternative use which is calculated in terms of other goods; while sunk cost is the money spent on goods which cannot be recovered, such as rent. Thank you for listening today. We hope you learned a little more about these topics today and their importance to economics. So long and stay safe.

1970s Oil Crisis and Stagflation

Podcast created by: Samuel Kerner, Katherine Bablin, and Mathew Faulkner

The 1970s were characterized by periods of stagflation in which unemployment and inflation both rose. The stem of the issue came from political tensions in Arabia which led to a disruption in the supply of oil for the rest of the world. The resulting energy shocks disrupted the economies of many countries around the globe that imported oil from OPEC nations. It has been investigated time and time again the extent to which these energy shocks affected the economy. Specifically, economists want to know how much of the resulting stagflation was due directly to the energy shocks themselves, and how much was due to the government’s monetary policy in response to the shocks. This podcast explores both sides of the debate between the oil shocks and monetary policy.

Educational Inequity and Income Inequality

Podcast created by: Tyler Bacon and Jason Lin

Education inequity is a recurring issue in many countries across the world. When looking at South Africa, Finland, and the United States, there is a significant difference in the county’s allocation of resources to education which includes government funding, education requirements, and technology resources. The largest discrepancies exist between developing and developed nations where in developing countries there is a focus of resources on primary education and attacking the lower literacy levels in countries such as South Africa. While developed nations such as the US and Finland allocate far more resources to that secondary education. Finding ways to spread resources across the entirety of a nation is key to reducing income inequality through the improvement of education inequity in larger nations such as the US.

Intergenerational Mobility In the USA

Podcast created by: Jared Jeziorowski and Khadejah Taylor

The aim of this podcast is to dissect economic and social disparities affecting minorities. Not just current disparities but also inequalities of the past and how those could impact people's intergenerational mobility for generations to come.

 

Educational Attainment and Income

Podcast created by: Samuel Kerner, Katherine Bablin, and Matthew Faulkner

The human capital theory suggests that acquiring more education and training adds to a person's skill and therefore increases productivity and efficiency. By this logic, those with more education should end up receiving higher salaries, thus there is a return to education. In this podcast we discuss how the rate of returns to education changes with the business cycle, noting the gap in the rate between women and men. Furthermore, whether or not one obtains education or not in the first place, as well as how much education they achieve depends on a variety of factors. Here, we hope to answer the question: is acquiring more education worth it?

Intergenerational Income and Educational Inequality

Podcast created by: Jason Lin and Tyler Bacon

There is an observed correlation between educational attainment and household income levels in the United States. When observing the statistics there are certainly advantages that higher income levels have over that of lower income households. This includes access to private education, tutoring services, and access to better public school districts with greater resources that lower income households don’t have access to in many cases. These advantages help contribute to the increased widening of the wage gap that is simultaneously affected by the increased demand for secondary education in the labor market. While there are other factors that can provide reasoning to education quality like cultural and social factors, the majority of inequity in education attainment correlates to different income levels.
