About Principles of Macroeconomics

Principles of Macroeconomics has been developed to meet the scope and sequence of most introductory macroeconomics courses. At the same time, the book includes a number of innovative features designed to enhance student learning. Instructors can also customize the book, adapting it to the approach that works best in their classroom.

Coverage and scope

To develop Principles of Macroeconomics , we acquired the rights to Timothy Taylor’s second edition of Principles of Economics and solicited ideas from economics instructors at all levels of higher education, from community colleges to Ph.D.-granting universities. They told us about their courses, students, challenges, resources, and how a textbook can best meet their and their students’ needs.

The result is a book that covers the breadth of economics topics and also provides the necessary depth to ensure the course is manageable for instructors and students alike. And to make it more applied, we have incorporated many current topics. We hope students will be interested to know just how far-reaching the recent recession was (and still is). The housing bubble and housing crisis, Zimbabwe’s hyperinflation, global unemployment, and the appointment of the United States’ first female Federal Reserve chair, Janet Yellen, are just a few of the other important topics covered.

The pedagogical choices, chapter arrangements, and learning objective fulfillment were developed and vetted with feedback from educators dedicated to the project. They thoroughly read the material and offered critical and detailed commentary. The outcome is a balanced approach to macroeconomics, to both Keynesian and classical views, and to the theory and application of economics concepts. New 2015 data are incorporated for topics, such as the average U.S. household consumption in Chapter 2. Current events are treated in a politically-balanced way as well.

The book is organized into seven main parts:

  • What is Economics? The first two chapters introduce students to the study of economics with a focus on making choices in a world of scarce resources.
  • Supply and Demand , Chapters 3 and 4, introduces and explains the first analytical model in economics: supply, demand, and equilibrium, before showing applications in the markets for labor and finance.
  • Elasticity and Price , Chapter 5, introduces and explains elasticity and price, two key concepts in economics.
  • The Macroeconomic Perspective and Goals , Chapters 6 through 10, introduces a number of key concepts in macro: economic growth, unemployment and inflation, and international trade and capital flows.
  • A Framework for Macroeconomic Analysis , Chapters 11 through 13, introduces the principal analytic model in macro, namely the Aggregate Demand/Aggregate Supply Model. The model is then applied to the Keynesian and Neoclassical perspectives. The Expenditure/Output model is fully explained in a stand-alone appendix.
  • Monetary and Fiscal Policy , Chapters 14 through 18, explains the role of money and the banking system, as well as monetary policy and financial regulation. Then the discussion switches to government deficits and fiscal policy.
  • International Economics , Chapters 19 through 21, the final part of the text, introduces the international dimensions of economics, including international trade and protectionism.

The long-run aggregate supply curve is a vertical line at the potential level of output. The intersection of the economy’s aggregate demand and long-run aggregate supply curves determines its equilibrium real GDP and price level in the long run. Am I correct?
Tadesse
so it will out vary
Tadesse
no one corrects me
Tadesse
yes no-one corrects you.
Frank
but I'm here to listen your answer
Frank
aggregate supply is total of all industry supply.
Frank
In the long-run, the aggregate supply is graphed vertically on the supply curve. The equation used to determine the long-run aggregate supply is: Y = Y*. In the equation, Y is the production of the economy and Y* is the natural level of production of the economy.
Frank
yes you're correct Mr. Tedessa

what will happen to the demand curve when there is an inflation in an economy
Hamza Reply
From my view, I think the demand curve will shift inwards.
Bobo
now it depends on what kind of inflation it is, depending on the type of inflation the movement of the demand curve can be stated.
Munimu
yes it depends on the cause for inflation. if it caused by maybe an increase in money supply, the effect is neutral in the long term, therefore there are no effects on total output in the economy, except for an increase in price
Lucas
but short term in general i think you could expect the demand curve to shift inwards as consumers experience a decrease in real income

Suppose you are holding 2000 in a checking account and the price level decrease by 20 %how much it will affect your purchasing power and why
Iqra Reply
Hi Iqra, will answer your question soon.
Aleem
2000*0.2= 400 2000-400= 1600
Munimu
1600
Munimu
a price level decrease is deflation. it means you'll be able to afford to buy more with your 2000 and your real income becomes 2000÷(100-20)=2500
Lucas
the amount will decrease to 1600 and you can't be able to buy over this amount

As an economist student discuss how the pandemic covid19 can affect the aggregate demand and aggregate supply thereby leading to decrease in GDP and standard of living of citizens of nigeria
Fadila Reply
pandemic covid19 has already resulted to recession among nations. Recession on the other hand, refers to a fall in aggregate demand due to low income, no or little savings, low productivity among firms, layoffs of workers and so on. currently, international trade is on the hold which has drastically

affected the GDP and GNP of countries. This to a large extent has affected the purchasing power of consumers
Okeoghene
Hence the standard of living is questionable among nations especially among developing nations
