Pedagogical foundation

Throughout the OpenStax version of Principles of Economics , you will find new features that engage the students in economic inquiry by taking selected topics a step further. Our features include:

  • Bring It Home: This added feature is a brief case study, specific to each chapter, which connects the chapter’s main topic to the real word. It is broken up into two parts: the first at the beginning of the chapter (in the Intro module) and the second at chapter’s end, when students have learned what’s necessary to understand the case and “bring home” the chapter’s core concepts.
  • Work It Out: This added feature asks students to work through a generally analytical or computational problem, and guides them step-by-step to find out how its solution is derived.
  • Clear It Up: This boxed feature, which includes pre-existing features from Taylor’s text, addresses common student misconceptions about the content. Clear It Ups are usually deeper explanations of something in the main body of the text. Each CIU starts with a question. The rest of the feature explains the answer.
  • Link It Up: This added feature is a very brief introduction to a website that is pertinent to students’ understanding and enjoyment of the topic at hand.

Questions for each level of learning

The OpenStax version of Principles of Economics further expands on Taylor’s original end of chapter materials by offering four types of end-of-module questions for students.

  • Self-Checks: Are analytical self-assessment questions that appear at the end of each module. They “click–to-reveal” an answer in the web view so students can check their understanding before moving on to the next module. Self-Check questions are not simple look-up questions. They push the student to think a bit beyond what is said in the text. Self-Check questions are designed for formative (rather than summative) assessment. The questions and answers are explained so that students feel like they are being walked through the problem.
  • Review Questions: Have been retained from Taylor’s version, and are simple recall questions from the chapter and are in open-response format (not multiple choice or true/false). The answers can be looked up in the text.
  • Critical Thinking Questions: Are new higher-level, conceptual questions that ask students to demonstrate their understanding by applying what they have learned in different contexts. They ask for outside-the-box thinking, for reasoning about the concepts. They push the student to places they wouldn’t have thought of going themselves.
  • Problems: Are exercises that give students additional practice working with the analytic and computational concepts in the module.

Updated art

Principles of Economics includes an updated art program to better inform today’s student, providing the latest data on covered topics.

U.s. minimum wage and inflation

After adjusting for inflation, the federal minimum wage dropped more than 30 percent from 1967 to 2010, even though the nominal figure climbed from $1.40 to $7.25 per hour.Increases in the minimum wage in 2007, 2008, and 2009 kept the decline from being worse—as it would have been if the wage had remained the same as it did from 1997 through 2006.

How does one analyze a market where both demand and supply shift?
Gabriel Reply
That's equilibrium market
Ramon
but an equlibrum can appear twice on the same market... both in Movement along the Demand/supply curve of shift in the Curve
Gabriel
I Mean on the same curve..
Gabriel
how can consumer surplus be calculated
Franklyn
How can we analyze the effect on demand or supply if multiple factors are changing at the same time—say price rises and income falls? 
Gabriel Reply
because of fall of income, less will be demanded and much will be supply as a result of price rises. Rise in price always motivate new supplier to enter into the system. But it only possible in the short run
Kweku
yeah.. I think Ceteris Paribus is applied in this case
Gabriel
that is the law of Demand is Inversely related to the law of Supply... so that mean a positive change in demand may produce a negative return to supply I think.
Gabriel
