The exchange rate in Orthodox, Keynesian and New Developmentalism theoretical models: a literature review

ABSTRACT The main purpose of this paper is to present the differences in the exchange rates in macroeconomic models from the three current theoretical views: Orthodox, Post-Keynesian and New Developmentalism. To achieve this objective, it is proposed to make a bibliographic survey of the literature on open macroeconomics and exchange rate. The main differences among these views concerns to exchange rate determination, causes of exchange rate variations and balance of payments equilibrium determination.

Assessing Monetary Model of Exchange Rate Determination: Case of Indonesia

The main purpose of this paper is to assess the exchange rate determination in Indonesia after the Asian financial crisis. We use the Monetary Model to assess the prediction of the Indonesian Rupiah against the United States Dollar and other currencies of the largest trade partners of Indonesia. The models are the Flexible Price Monetary Model and the Sticky Price Monetary Model. We estimate short-run and long-run relationships using the Error Correction Model. The Monetary Model can explain partially the exchange rate variations, but the signs of money, income, and fiscal balance are not as expected. The causality may run from the exchange rate to money and price level.

Exchange Rate Determination: The Portfolio-Balance Approach

The portfolio-balance approach to exchange rate determination is part of the Asset Market Models and is largely attributed to economists after 1973 when the exchange rate became flexible (market determined). This article first introduces the setting of the model embedded in the portfolio balance approach that encompasses two assets (money and bonds), which deviates a little from the models and approaches used for the monetary approach to the balance of payment, the overshooting model, and from the associated market equilibria. The effects of monetary policy, of current account, and of wealth under the portfolio-balance approach are examined, here, theoretically and empirically. The current econometric results show that the exchange rate is determined by the foreign bonds, the domestic interest rate, and the foreign interest rate.
