The General Theory of Employment, Interest and Money is a book by English economist John Maynard Keynes published in February 1936. It caused a profound shift in economic thought, [1] giving macroeconomics a central place in economic theory and contributing much of its terminology [2] – the "Keynesian Revolution".
Dynamic stochastic general equilibrium modeling (abbreviated as DSGE, or DGE, or sometimes SDGE) is a macroeconomic method which is often employed by monetary and fiscal authorities for policy analysis, explaining historical time-series data, as well as future forecasting purposes. [1]
[2] [3] Macroeconomists study topics such as output/GDP (gross domestic product) and national income, unemployment (including unemployment rates), price indices and inflation, consumption, saving, investment, energy, international trade, and international finance. Macroeconomics and microeconomics are the two most general fields in economics. [4]
Nevertheless, Dornbusch concludes that monetary policy is still effective even if it worsens a trade balance, because a monetary expansion pushes down interest rates and encourages spending. He adds that, in the short run, fiscal policy works because it raises interest rates and the velocity of money.
The argument begins from the observation that in equilibrium, total income must equal total output. Assuming that income has a direct effect on saving, an increase in the autonomous component of saving, other things being equal, will move the equilibrium point, at which income equals output to a lower value, thereby inducing a decline in saving that may more than offset the original increase.
Marshall's original introduction of long-run and short-run economics reflected the 'long-period method' that was a common analysis used by classical political economists. However, early in the 1930s, dissatisfaction with a variety of the conclusions of Marshall's original theory led to methods of analysis and introduction of equilibrium notions.
Another example of a model in ecological economics is the doughnut model from economist Kate Raworth. This macroeconomic model includes planetary boundaries, like climate change into its model. These macroeconomic models from ecological economics, although more popular, are not fully accepted by mainstream economic thinking.
[3]: 195–201 Similar models, though called slightly different names, appear in the textbooks by Charles Jones [15] and by Wendy Carlin and David Soskice [14] and the CORE Econ project. [14] Parallelly, texts by Akira Weerapana and Stephen Williamson have outlined approaches where the LM curve is replaced with a real interest rate rule. [15] [16]
