This paper proposes an equilibrium theory of nominal exchange rates, which offers a new perspective on various issues in open economy macroeconomics. The nominal exchange rate and portfolio choices are jointly determined in equilibrium, thus providing a new approach to overcoming the...

This paper discusses the use of nominal exchange rates as nominal anchors in stabilization programs. The first part deals with the dynamics of inflation in highly indexed economies. It is shown that credible exchange rate anchors will reduce the degree of inflationary inertia. However, if some...

In this paper we estimate and compare several alternative exchange rate models that have received wide attention, but little comparison, during the 1970s. In order to compare purchasing power parity (PPP), nominal interest rate parity, real interest rate parity, and portfolio balance models, we...

The New Open Economy Macroeconomics has allowed economists to tackle classical problems with new tools, while also generating new ideas and questions. In their attempts to make the new models capture empirical regularities, researchers have entertained a variety of assumptions about the...

This paper develops a highly simplified model of exchange rate behavior within the band under a target zone regime. It shows that the expectation that authorities will defend the band exerts a stabilizing effect on exchange rate behavior within the band, even when the authorities are not...

At the aggregate level, the evidence that deviations from purchasing power parity (PPP) are too persistent to be explained solely by nominal rigidities has long been a puzzle (Rogoff, 1996). Another puzzle from the micro price evidence of the law of one price (LOP), which is the basic building...

In veiw of recent strong evidence that substantial sterilization of the monetary effects of reserve flows occurs, a modified monetary approach model is formulated in which central banks exercise no control over their domestic money supply despite their sterilization activities. This model is...

The prevailing exchange rate and its volatility has been always an important issue in an open economy and freely floating exchange rate system, such as in Indonesia. In this system, the exchange rate is allowed to fluctuate based on the interaction between demand for and supply of foreign...
