A model of currency depreciation and the debt-inflation spiral


  • Obstfeld, Maurice


This paper shows how a government that cannot make credible policy commitments might manage its exchange rate and fiscal stance in a world of rational expectations. The dynamic-game model developed here potentially can generate diverse patterns of macroeconomic behaviour, patterns that differ as a result of assumed differences in government objectives. Under some types of government, the ongoing strategic interaction between the public and private sectors leads to a disinflationary outcome. Other governments may push the economy into a spiral of rising debt and inflation.
