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.
Subsequently, the term âKeynesian economicsâ was used to refer to the concept that optimal economic performance could be achieved â and economic slumps prevented â by influencing aggregate demand through activist stabilization and economic intervention policies by the government.
