I. Macroeconomic Forces: Output, Money, and Expectations
Macroeconomics revolves around three major forces: output, money, and expectations. Their interaction dictates the health and direction of an economy.
I.1 Understanding Output
Output is the foundation of a wealthy nation. Ultimately, output per capita, not just money per capita, determines prosperity. Gross Domestic Product (GDP) is a key measure of output, typically calculated using the expenditure method: GDP = C + I + G + NX (Consumption + Investment + Government Spending + Net Exports).
- A negative Net Export (NX) value indicates that a country is consuming more than it produces, leading to borrowing from abroad (imports exceed exports).
Output can increase through:
- Increased labor
- Increased capital
- Growth in Total Factor Productivity (TFP)
Two primary approaches to economic growth exist:
- Supply-Side Economics (Reaganomics/Trickle-Down): Focuses on increasing output by incentivizing producers. Reducing taxes is a common tool to boost wages, consumption, and investment, ultimately driving Research & Development (R&D) and TFP.
- Keynesian Economics: Advocates for managing demand through government spending and lower taxes, utilizing monetary and fiscal policy.
Recessions occur because prices and employment can be inflexible in the short run. Long-term economic downturns are often triggered by unexpected shocks.
I.2 The Role of Money
Money has three key prices: interest rates, exchange rates, and the aggregate price level (inflation). Increasing the money supply typically leads to lower interest rates, currency depreciation, and higher inflation.
The interplay between these factors is crucial. For example, real GDP increases when output rises, while nominal GDP rises when both output and prices increase. If the money supply increases, nominal interest rates might fall, but expectations of inflation can push them back up.
Money illusion occurs when people focus on nominal income increases without considering the impact of inflation.
Central banks manage the money supply through:
- Discount rates (the rate at which banks can borrow from the central bank).
- Reserve requirements (the fraction of deposits banks must hold in reserve).
- Open market operations (buying or selling government bonds).
I.3 The Power of Expectations
Expectations significantly impact economic outcomes. If inflation is expected to rise, businesses may increase prices, anticipating wage increases, leading to a self-fulfilling prophecy. Similarly, pessimism about the future can lead to increased savings and reduced consumption, causing GDP to fall below optimal levels.
Two potential solutions to manage expectations include:
- Monetary Policy: Can be ineffective during a liquidity trap when interest rates are near zero. This diminishes the incentive to convert money into financial assets, increasing the demand for cash and keeping rates stagnant.
- Fiscal Policy: Increasing government spending (G) in the GDP equation (C + I + G + NX). However, increasing government spending during full employment can lead to inflation, while during low employment, it can increase both output and prices.
II. Macroeconomic Applications
II.1 A Look at US Monetary History
Historically, the gold standard aimed to be self-regulating. Inflation would increase prices, leading to increased imports, gold leaving the country, and ultimately a rise in the domestic price of gold, causing inflation to fall. However, this system saw wild rate fluctuations due to seasonal demand for money.
II.2 Understanding GDP Accounting
The expenditure method is the preferred way to calculate GDP, representing the final expenditure on all goods and services. Net Domestic Product (NDP) is GDP less depreciation, but accurately measuring depreciation is practically challenging. Gross National Product (GNP) measures output by residents of a country, regardless of location, while GDP measures output within a country’s borders.
II.3 Reading Balance of Payments (BOP) Statements
BOP statements track cross-border transactions. The financial account line item under the capital account is particularly important. Omissions in these statements can sometimes reveal hidden capital flight, where individuals discreetly move assets out of the country. The BOP operates on a double-entry system where credits represent sources of foreign exchange (FX) or an increase in liabilities or a decrease in assets. Debits represent uses of FX, or increases in assets or decreases in liabilities.
II.4 Understanding Foreign Exchange (FX)
A current account surplus indicates strong demand from foreigners for a country’s goods and services. Higher inflation typically leads to long-term currency depreciation. Rising interest rates can increase demand for a currency as foreigners seek higher returns on financial assets.
II.5 Connecting Output, Expectations, and Money
Money supply affects inflation, interest rates, and exchange rates. Macroeconomics deals with money supply. For example, when it increases, nominal GDP goes up, but real GDP (measured in constant currency) may not, as real GDP measures output increases, not price increases due to inflation. Macroeconomics also deals with policies designed to shape expectations, which can ultimately drive economic reality.
