Abstract In the presence of frictions, the existing literature shows that currency substitution is detrimental for domestic aggregate stability. This paper singles out the role of currency substitution and shows that diversified currency holdings operate as an automatic stabilizer that mitigates belief-driven cyclical fluctuations in Farmer’s (1997) indeterminate monetary economy. When the foreign inflation rate is lower than the domestic inflation rate, the model’s steady state always displays saddle-path stability. Hence, equilibrium indeterminacy originally present in the domestic country is entirely removed in the presence of diversified currency holdings. When the foreign inflation rate is higher than the domestic inflation rate, then depending on the degrees of currency substitution and relative risk aversion, indeterminacy is either impossible or the requisite level of the foreign inflation rate for indeterminacy is too high to square with data. The stabilizing effect of diversified currency holdings on domestic aggregate stability is robust to whether domestic and foreign currencies display as Edgeworth substitutes or complements, or are additively separable in the household’s preferences.

This paper explores the role of employment protection when powerful external crises reduce demand for products. We first present a theoretical framework that shows that employment protection has a U-shaped effect on abnormal unemployment during a negative exogenous shock to an economy. Using data from the 33 OECD countries, we analyze how the level of employment protection affected the stability of unemployment rates during the recent global economic crisis. The results suggest that countries with an intermediate level of employment protection will have more stable unemployment rates during a world crisis. The policy implication of our paper is that countries should seek a medium level of employment protection that may act as an automatic stabilizer of the economy on the macro level.

Fifty Years of Development Economics, Essays in Hon­our of Professor P.R. Brahmananda, Editors A. Vasedevan, D.M. Nachane, A.V. Karnik, Foreword Lord Meghnad Desai, Himalaya Publishing House, Mumbai 400 004, First Edition - 1999.   This Volume is a collection of 30 essays, writ­ten in honour of Professor P. R. Brahmananda, a dis­tinguished economist in India. The essays in this book focus on a number of issues such as theory and meas­urement, Indian policy framework, snictural reforms, regional perspectives and provide rich insight on vari­ous subjects. The book also documents empirical stud­ies researched by well-known economists.   The first part of the book with 8 chapters deals with theory and measurement of money, inflation etc.. In this part, Nachne's paper on "Commodity Stand­ards: Resurrection of a Classical Theme" revisits the issues relating to the concept of money standard and questions, the role of the Govenment in controlling money. The author, while reviewing the role of gov­ernment in controlling the monetary policy in histori­cal retrospection, examines a umber of alternative proposals. He chooses, amongst others, commodity standard, and analyses it to find out its relevance to modetary policy. His contribution lies in explaining the Black-Fama-Hall (BFH) model-Commodity Basket Model. This model has been discounted as it does not take into account expextations and has difficulties in choosing the commodities for the basket. The BFH model has a few advantages like a stable unit of ac­count, subjects the government to financial discipline, can stipulate financial innovations and can insulate the economy from cyclical fluctuations originating domes­tically. Nachne's contribution lies in simplifying the analysis on the difficult subject.   Inflation has been a long drawn riddle in many countries like Brazil, Turkey, India. Control of infla­tion has been enforced in many countries to bring macro economic stability with high economic growth. Vasudevan, Bhoy and D hall have tried to trace equi­librium between inflation and growth rate in the In­dian context. They reached a conclusion that inflation, growth trends and their volatility, when analysed si­multaneously, reveal that a moderate rate of inflation on an average centered between 6 to 8 per cent in In­dian economy with low volatility, led to high growth rates. The authors have used regression robust error technique after taking recourse to a number alterna­tive empirical modes as suggested in the literature. The findings of the present exercise indicate that the thresh­old rate of inflation in the Indian context could be about 6 per cent; the output neutral inflation could be 4 per cent. The output effects are positive but marginally different from one another for the 5, 6 and 7 per cent inflation regimes. The negative output effects occur after 10 per cent inflation rate.

This paper highlights the role of external indebtedness and the presence of inflationary inertia in order to assess the effectiveness and sustainability of inflation targeting during disinflation episodes. As the recent Argentinian experience illustrates, a sluggish inflation rate and a significant current-account deficit may make the stabilization process difficult. To illustrate the point, we build a model that shows that, when inflation adjusts fast, the target may be achieved without building too much external debt. But if inflation adjusts slowly, an excessive build-up of external debt could lead to an increase in the risk premium, a sudden shortage of foreign exchange, and the eventual collapse of the inflation-targeting regime.

This paper examines the role of inflationary threshold effects in the finance-growth relationship for Ghana and Nigeria. Ghana and Nigeria are relatively homogenous in terms of financial development, economic growth, and inflationary history and therefore provide an acceptable choice for this empirical analysis. Due to lack of data availability, the sample spans the period 1964–2011 for Ghana and 1961–2011 for Nigeria. Using appropriately specified threshold regressions, we found inflationary thresholds in both countries during the study periods. Specifically, the inflationary threshold range for Ghana is 10.73 %–29.83 %. For Nigeria, the inflationary threshold range is 10.07 %–19.25 %. By estimating the threshold regressions, we found financial development to have positive and significant effect on economic growth during low and moderate inflationary regimes; and insignificant effect on growth during high inflationary regimes, for both countries. In particular, financial development impact greatly on growth in Ghana when the rate of inflation is below a threshold of 10.73 % but dissipates when inflation rate reaches and exceeds 29.83 %. Similarly, financial development impact greatly on growth in Nigeria when the rate of inflation is below a threshold of 10.07 % but dissipates when inflation rate reaches and exceeds 19.25 %. The results imply that policymakers in these countries should take inflation into account when devising policies to promote financial development with the aim of generating economic growth. For without low or moderate inflation rates, such policies will not achieve their intended purposes.

This paper discusses the NAIRU—the non-accelerating inflation rate of unemployment. It first considers the role of the NAIRU concept in business cycle theory, arguing that this concept is implicit in any model in which monetary policy influences both inflation and unemployment. The exact value of the NAIRU is hard to measure, however, in part because it changes over time. The paper then discusses why the NAIRU changes and, in particular, why it fell in the United States during the 1990s. The most promising hypothesis is that the decline in the NAIRU is attributable to the acceleration in productivity growth.
