Overview

Today we move our focus to economic aggregates. We seek to explain why economies work as they do. We begin by exploring the relationship between investment in an economy, government spending and consumption for the goods market to be in equilibrium, savings must balance investment; and aggregate demand for goods must balance their production. Not all goods and services consumed (or invested) in an economy are produced locally, so we also need to account for foreign trade. In the second lecture we introduce prices and the labour market. The aim is to explain what drives inflation and unemployment. We also qualify what we mean by an economy being in equilibrium. However an open economy needs to find an equilibrium in its domestic markets in response to the pressures of money and goods travelling into and out.  Our analysis cannot be complete without considering the response of the international markets and this will be in large part mediated via the exchange rate. Thus in the third lecture we consider the determinants of exchange rates. We also discuss how misaligned exchange rates reflect on balance of payments problems. In the final lecture we extend our horizon to the long run, which means ignoring the business cycle, to study how economists explain why certain economies grow faster than others. The lecture has a policy focus by asking what governments can do, if anything, to raise a country’s long run growth rate.
