At the core of Austrian Economics are people voluntarily transacting in goods and services. Building rational arguments based upon knowledge of human behaviors, Austrian Economics creates a consistent theory of economics that explains macro-economic phenomena from many individual micro-economic transactions. Classical micro-economics is therefore one of the basic fundamentals of Austrian Economics, and a solid understanding of classical supply and demand models and how prices are determined in the free market are essential to the understanding of Austrian Economics. I am also starting here because many people will be familiar with these lessons and are likely to agree with them because they have widespread acceptance among many schools of economic thought. I have found these lectures on youtube to convey this basic lesson.
