Understanding economic policymaking

We are surrounded by news and commentary on the macroeconomy. To understand it, we need to grasp the meaning of GDP, inflation and unemployment and see what their “normal” levels are and how they relate to one another. Though these levels and relationships are far from mechanical, they provide an essential foundation to understanding what governments are doing in a macroeconomy.

Welcome to Module 2! We will be going into fiscal policy, which is one of the key tools that authorities have to influence the economy and bring GDP closer to its ideal growth rate. It consists of changes in government spending and taxes. To try to gauge how much spending and taxes need to change to bring GDP to potential, we use two concepts: the multiplier, and crowding out. However, spending and tax revenues also move automatically across the business cycle, helping make the economy more stable. Thanks for being with us! Enjoy learning!

Welcome to Module 3! Now we know how fiscal policy is supposed to work in the economy, to close recessionary or inflationary gaps. In this module we will get into the nuts and bolts of deficits and debts in the real world and I am sure we will have some interesting follow-up discussions! How is it really used? What are government deficits and debts? When governments run deficits and need to borrow money, how and where do they do it? When are these deficits and debts more of a problem? This module will look at the US and other leading economies in recent years to answer these questions, clear up some common misconceptions, and point to what the most important concerns are with deficits and debts at the present time. Good luck and see you online!

Welcome to Module 4! This week we're tackling a fascinating issue, which is monetary policy, and I anticipate some very interesting debates. Monetary policy is the other main tool that governments can use to influence the economy. Monetary authorities work through the money supply and can use open market operations, their own lending rates and reserve or cash ratios to influence money markets and hence the real economy. Just as with fiscal policy, once the gap in the economy is identified, expansive monetary policy should be used in a recessionary gap and restrictive monetary policy in an inflationary gap. Monetary policy is superior to fiscal policy in many ways, but its greatest weakness is that it does not work nearly as well in recessionary gaps as in inflationary gaps. Keep up the good work!
