Inflation and the Exchange Rate: The Role of Aggregate Demand Elasticity

This paper examines the effect of aggregate demand elasticity on the exchange rate when inflation occurs. We discover that both the source of the inflation, whether demand-pull or cost-push, and the elasticity of aggregate demand with respect to the price level, are of consequence for the exchange rate. We obtain two primary conclusions. First, the effect on the exchange rate of cost push inflation is ambiguous and is partially determined by the price level elasticity of aggregate demand. In particular, and assuming that the two examined countries have equivalent aggregate supply elasticities, we conclude that the nation with the less elastic aggregate demand function will see its currency appreciate relative to the other. Second, demand-pull inflation results in an unambiguous increase in the exchange rate but the size of that increase is partially a function of aggregate demand elasticity. Assuming again that two countries have equivalent aggregate supply elasticities, that country with the more elastic aggregate demand will experience currency appreciation

A Note on Government Budgets

The standard pedagogical examination of government budgets includes the distinction between cyclical and structural deficits and surpluses and changes thereof. This paper extends the regular classroom analysis and graphically demonstrates that cyclical changes in the government budget can be decomposed and stated as the summation of the expenditure effect and the revenue effect

Economic Expansion and the Balance of Trade: The Role of Aggregate Demand Elasticity

This paper investigates the role of aggregate demand elasticity for the balance of trade when economic expansion occurs. Our conclusions are two. First, when an economic expansion results from an increase of aggregate demand, the balance of trade deficit is larger the less elastic is aggregate demand with respect to the general price level. Second, when an economic expansion happens from an increase of short-run aggregate supply, the price level elasticity of aggregate demand determines both the direction of change of the balance of trade and the size of the resulting deficit or surplus. We show here that a relatively elastic aggregate demand can result in a balance of trade deficit while a relatively inelastic aggregate demand can yield a balance of trade surplus

Implications Of Aggregate Demand Elasticity For The Phillips Curve

While the general relationship between the aggregate supply curve and the Phillips curve is recognized, the importance of aggregate demand and, in particular, aggregate demand elasticity, for the inflation-unemployment relationship has been untreated. We believe, however, that the elasticity of aggregate demand with respect to the general price level does have some significance for the short-run Phillips curve since, on a general level, the economy's equilibrium price level, inflation rate, real gross domestic product, and unemployment rate are determined jointly by aggregate supply and aggregate demand. The primary purpose of this paper then is to demonstrate with a graphical analysis the implications of aggregate demand elasticity for the Phillips curve.
