1)What is the best macroeconomics MOOC?

2)Do Burton Malkiel's Random market findings imply that linear macroeconomic models cannot ever describe reality?

3)What are the most useful theories, indicators, or formulas for macroeconomic understanding?

1)The Fundamentals of Macroeconomics is the best online course to sign up. This certification is vital for folks who want to solidify their basics in economics. In short, this course entails the critical topics economists need to know about markets. Furthermore, the students can explore the strengths and failures of markets, thus, understand the relevant economic problems. Also, no experience is required to sign up for the course. By the end of the course, students can answer any fundamental question asked in macroeconomics.

The reasons why this is the best macroeconomic course are:

• It provides a great insight into the importance of Gross Domestic Product, its components and measurements.
• Student can comprehend the financial system, capital flow, and monetary policies.
• The entry-level certification requires knowledge of mathematics and ability to understand basic graphs.
• By the end of the course, one can understand and be able to analyze the economy of any country
• Furthermore, the lecturer uses real-life examples and teaches with visual arguments; thus, students can connect the concepts with their own experiences.

2)Yes, Burton Markel's findings imply that linear functions cannot be accurately used to predict reality. In the stock market, investment advisors use the current value of stocks to calculate the intrinsic worth of companies. However, Burton's Random market theory points out that stock price is dependent on unforeseen random variables rather than the past established variables. Therefore an individual with no prior knowledge of the stock market can make a successful move in the stock investment decision. According to Burton's theory, the information used to develop economic models is usually incorrect; hence, these models cannot be used to describe occurrences in reality. Data used to build the models may also be wrongly interpreted. It points out that different factors in an economic model act independent of each other; therefore, one economic variable cannot be used to predict the value of a factor accurately. Consequently, the established macroeconomic models are not sufficient in describing business reality.

The most useful theories and indicators enhancing the understanding of macroeconomics include:

• Keynesian theory. It argues about the effects of total spending on inflation as well as economic output. The theory explains the need for increased government expenditure and low taxation to accelerate aggregate demand hence minimizing the occurrence of the depression.
• Monetarist theory. It argues that changes in the supply of money play a crucial role in determining economic growth as well as business cycles.

The main economic indicators include:

• Gross Domestic Product (GDP). It helps in determining the performance of the economy. Basically, an increase in GDP signals sound performance of the economy, while a decrease shows poor performance.
• Unemployment indicators. Economic growth leads to the creation of job opportunities hence solving the problem of unemployment. The contrary happens in a deteriorating economy leading to high levels of unemployment.
• Consumer price index. It helps in determining the levels of inflation in an economy by analyzing changes in prices of consumer goods and services.
