This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"For thousands of years, the Nile has provided bountiful gifts to the people who make their home around its banks, offering food, a means of transport, irrigation, and fertile soil. But there is a limit to how much the Nile can give. Already in the 1970s, Egypt began fully utilizing the available resources of the Nile. Any additional demand has been met virtually, through imports of food. Now, research suggests that within the next decade, Egypt is poised to import as much “virtual water” as it receives from the Nile. In a new study from MIT, researchers compiled water and crop data for Egypt spanning the past 60 years. That gave them one of the most detailed looks at modern water use ever produced for the country, and helped them understand Egypt’s trade in “virtual water”. Virtual water refers to the hidden flow of water in food and commodities. For example, it takes about 1100 tons of water to produce one ton of maize in Egypt..."

The rest of the transcript, along with a link to the research itself, is available on the resource itself.

Principles of Macroeconomics 2e covers the scope and sequence of most introductory economics courses. The text includes many current examples, which are handled in a politically equitable way. The outcome is a balanced approach to the theory and application of economics concepts. The second edition has been thoroughly revised to increase clarity, update data and current event impacts, and incorporate the feedback from many reviewers and adopters.Changes made in Principles of Macroeconomics 2e are described in the preface and the transition guide to help instructors transition to the second edition.

With this free video resource, students will explore the economic way of thinking, and the role incentives play in all our lives through engaging Hollywood production style videos.

Educators can use MRU's videos in a variety of ways, to include “flipping” the classroom, as study aids, supplementary material, concept reinforcement, or even as a full course offering.

In MRU's Principles of Macroeconomics course, we’ll cover fundamental questions such as: Why do some countries grow rich while others remain poor? How important is a country’s banking system — and what happened during the recent financial crisis? How did Zimbabwe end up with an inflation rate that rose into the quadrillions?

We’ll also cover important topics like the Federal Reserve, monetary policy, fiscal policy, the Solow Growth Model, institutional analysis, the “economics of ideas,” and more.

What is Marginal Revolution University (MRU)?

Many of us can remember our first great economics teacher who fundamentally changed how we see the world. At MRU, we try and deliver that experience to millions worldwide through video.

Founded as a nonprofit in 2012 by George Mason University economics professors Tyler Cowen and Alex Tabarrok, MRU is building the world’s largest online library of free economics education videos -- currently weighing in at more than 800 videos.

In this presentation, we will discuss how tourism affects different local communities, including Zanzibar. A study from Zanzibar published in 2015 found that only 20 percent of the GDP generated by tourism occurred to local communities, so it seems possible to develop forms of tourism with greater benefits to the population of Zanzibar, including local population.

Is there a recipe for economic growth? Perhaps some Miracle-Gro for the economy? If only it were that easy. While the exact recipe is a mystery, economists have identified some of the key ingredients. The September 2013 issue discusses the role that economic institutions play in fostering long-term economic growth.

Economists have long been interested in the causes of the business cycle. In this video we define the business cycle, discuss potential reasons it exists, and explore how it may be driven by emotion. Created by Sal Khan.
