Economic stability refers to the an absence of excessive fluctuations in the macroeconomy. An economy with fairly constant output growth and low and stable inflation would be considered economically stable. An economy with frequent large recessions, a pronounced business cycle, very high or variable inflation, or frequent financial crises would be considered economically unstable.
In the short run, economic theories are based on the assumptions of given resources and technology. ADVERTISEMENTS: These assumptions relate to a static economy where there is movement but no change. But in the long run, labour, capital and other resources and technology are assumed to change in certain theories. They relate to a dynamic economy. However, most economic theories are based on the assumption of a static economy.
