Study Notes
Understanding Macroeeconomics I: A Journey Through History
The world of economics isn't confined solely to individual transactions between buyers and sellers; it also encompasses vast systemic views of national economies, markets, and economic policies—this is where macroeconomics comes into play. In this introductory exploration of Macroeconomics I, we delve into the evolutionary path of our field and its major developments over time.
Classical Economists: Uncovering Economic Laws
In the 18th century, classical economists such as Adam Smith, David Ricardo, Thomas Malthus, and John Stuart Mill set forth foundational principles and theories regarding wealth creation, value taxation, land rent taxes, and population theory. These thinkers believed in the existence of natural laws governing the economy, with market forces reaching equilibrium through price adjustments without government intervention.
Keynesian Revolution: Reconstructing Economy during Depression
During the Great Depression, John Maynard Keynes proposed his groundbreaking General Theory, challenging the laissez-faire perspective introduced by the classics. According to Keynes, unemployment could persist even when workers were willing to work for lower wages due to falling demand and insufficient aggregate expenditure. His model emphasized activist fiscal policy, especially government spending and deficit financing, which he believed would boost employment and stimulate demand.
Monetarism: Money Matters More Than Ever
Monetarism emerged in the late 1960s, inspired by Milton Friedman, who argued that money supply was a primary determinant of inflation. This school of thought suggested that increasing the money supply would result in higher prices while decreasing the supply would lead to deflation. Policy prescriptions included tight control over monetary aggregates like the money multiplier and M2 growth rate.
New Classicals and Rational Expectations: Neoclassicism Takes Over
Established in the early '70s, new classical and rational expectations schools led by Robert Lucas Jr., Thomas Sargent, Neil Wallace, and others ushered neoclassical economics forward. They postulated that agents possess perfect information, act rationally, and make forecasts based on their beliefs about future events. Their models highlighted the role of self-fulfilling prophecies in driving business cycles and financial instability. Interestingly, these theories also downplayed the importance of government actions in stabilizing macroeconomy.
Real Business Cycles: From Supply Shocks to Demand Fluctuations
Real Business Cycle (RBC) theory emerged in the mid-eighties, pioneered by Nobel Laureate Dale Jorgenson, culminating from a collaboration between finance and real business cycle theory. RBC explains business cycles primarily as consequences of production shocks rather than consumption fluctuations. An essential premise of RBC revolves around labor mobility and wage flexibility, allowing markets to quickly clear after any disturbance.
While each era contributes insights to modern macroeconomics, it's crucial to recognize limitations, flaws, and ongoing debates within every paradigm shift. As scholars continue evolving our understanding of complex social systems underpinning macroeconomics, one thing remains clear - history has been integral to molding our current concepts, laying a solid foundation for further macroeconomic advancement.
