Hyperinflation in a small open economy with a fixed exchange rate: A post Keynesian view

This paper examines the emergence of hyperinflation in a small open economy with a fixed exchange rate from a post Keynesian perspective. Three variables play key roles: distributive conflict, external debt, and expectations about the exchange rate. First, we propose a short-run Kaleckian macro model. Then, we study the long-run behavior of the model by endogenizing the price level and foreign indebtedness. We conclude that the existence of expectations about the nominal exchange rate is crucial to explaining the emergence of hyperinflation.     

Domestic financial market frictions,unrestricted international capital flows,and crises in small open economies

Summary. We present an example of a small open economy where small increases in the world interest rate may induce a sharp decline in output and a precipitous depreciation of the exchange rate. Due to a costly state verification problem in domestic credit markets, combined with unrestricted international capital flows, our economy generates two long-run equilibria, one with low GDP and a relatively depreciated real exchange rate (RER), and one with high GDP and a relatively appreciated RER. The first is always a saddle, while the second may be a sink or a source, depending on the level of the world interest rate. A crisis is identified with the economy switching from an equilibrium path approaching the high-output steady state to the saddlepath approaching the low-output steady state. In Mexicos recent history, periods of growth associated with appreciation of the RER have alternated with periods of sharp contraction and depreciation of the RER. Our economy displays such behavior in response to changes in the world interest rate.Received: 9 April 2002, Revised: 20 March 2003JEL Classification Numbers: E5, F4.G. Antinolfi, E.

A prototype model of the foreign exchange market of Canada: Forecasting capital flows and exchange rates

A balance-of-payments structural model of the foreign exchange market of Canada, endogenizing capital flows, the spot and forward exchange rates and the entities of the monetary sector, is developed using quarterly data for 1971–81. The capital flows have been disaggregated into ten categories and the exchange rates of the Canadian dollar have been analysed against five major currencies. While the model does not adhere strictly to purchasing power or interest rate parity, it does recognize them and it also incorporates other economic fundamentals, expectations and risk. Government interventions, although generated endogenously, are quantified implicitly and globally. The model tracks the post-Bretton Woods in-sample experience and generates ex post predictions reasonably well.     

The determinants of international reserves in the small open economy: The case of Honduras

The strong monetary approach to the balance of payments suggests that for a small open economy with a fixed exchange rate, international-reserve losses are due to money-supply growth in excess of growth in money demand, where money demand is assumed to be a stable function of exogenously given income and world prices. This paper tests the applicability of the strong monetary approach to Honduras during the period 1960–1983. Although the strong monetary approach provides a statistical explanation of reserve movements during this period, insights into the underlying causes of reserve changes can be obtained through recognition of the importance of the income terms of trade in determining both real income and domestic-credit growth in the small open economy.     

Public infrastructure for production and international trade in a small open economy: a dynamic analysis

This paper develops a dynamic trade model with a stock of public infrastructure, which has a property of “unpaid factor of production”. We show that a country with a smaller (larger) labor endowment tends to become an exporter of a good whose productivity is more (less) sensitive to the stock of public infrastructure. We also show that after the opening of trade, the labor-scarce country becomes unambiguously better off but the labor-abundant country may become worse off. Overall, these results contrasts with those obtained in the case of public intermediate goods with a “creation of atmosphere” property.     

The interest-rate management and sterilization hypotheses for the UK: under fixed exchange rates

This study uses the vector autoregressive (VAR) technique and Granger's definition of causality to examine the interest rate management and sterilization hypotheses of UK for the period 1955.I to 1974.IV. Our findings show that neither the long-term government bond yield nor long-term treasury bill rate of UK can be considered as a policy-determined variable, since each is subject to feedback from UK and US monetary and income variables. In regard to the sterilization hypothesis, our results indicate that the UK domestic credit is an exogenous variable with respect to UK foreign reserves and interest rates. This result supports the implication of the monetary approach to the balance of payments that there was no sterilization in the UK during the fixed exchange rate period.     

Introduction: macroeconomic implications of capital flows in a global economy

The papers in this volume address issues raised by the wave of financial crises that hit emerging markets since the mid 1990s. Several of the papers examine the role that different credit market frictions may have played in triggering the crises, or in determining the effects of policies aimed at containing them. Other papers ask more general questions about the implications of international financial integration for business cycles, risk sharing, and sovereign lending.     

A structural model of price and exchange rate dynamics in a small open economy

Conclusions A major result following from the analysis of ourstructural model of inflation under flexible exchange rates is that there is no such thing asstructural inflation in the long run. Long-run inflation rather becomes a purely monetary phenomenon if exchange rates are flexible and if on an international level functioning capital markets are postulated. While, in the light of the assumptions made in Part III, this finding is not nearly as paradoxical as it may appear at first sight, it can hardly be overemphasized considering the ongoing theoretical discussion and the empirical research on the Scandinavian approach to inflation and recalling that the Scandinavian model is basically intended to picture equilibrium dynamics.The results concerning equilibrium price and exchange rate dynamics also apply to the equilibriumlevels of prices and the exchange rate, i. e., the equilibrium price level depends exclusively on monetary factors while the equilibrium exchange rate is determined by a purchasing power parity element and the structural productivity gap component.Turning to the results of our analysis of disequilibrium dynamics, the overall picture does not change very much. Here the qualitative pattern of adjustment of both prices and the exchange rate is again completely independent of structural variables, but is exclusively determined by four adjustment coefficients. However, the particular quantitative values assumed by prices and the exchange rate during the adjustment process do indeed reflect the impact of the productivity gap.No conclusions can be derived from our model on the amount of time it takes to return to the neighbourhood of equilibrium once the economy has been subjected to some kind of external shock. A casual examination of post-1973 developments and especially the Swiss experience suggest, however, that in the case of a disturbance as, e. g., in the form of a monetary contraction (relative to the rest of the world), the economy may take so long to return to the neighbourhood of long-run equilibrium that the negative real consequences of the overvaluation of the domestic currency during the adjustment process provide a momentous rationale for short-run stabilization interventions in the foreign exchange market.We should like to thank Peter Bernholz and an anonymous referee for helpful comments on a previous version of this paper.     

Economic liberalization, capital mobility and informal wage in a small open economy: A theoretical analysis

Empirical evidence suggests that the size of the informal sector in the developing countries has increased considerably during the liberalized economic regime. The present paper purports to analyze the consequences of economic reforms on the wellbeing of the informal sector workforce using a three-sector general equilibrium model with two informal sectors. The theoretical analysis finds that different liberalized policies produce diverse effects on the informal wage and that these results are independent of the nature of capital mobility between the informal and the formal sectors. It also shows that labour market reforms, contrary to the common wisdom, are likely to produce favourable effects on the informal wage.     

Real interest rates,inflation and the open economy: A regime-switching perspective on Australia and New Zealand

We investigate the time-series properties of Australian and New Zealand real interest rates within a Markov-switching framework. This enables us to identify characteristics in real interest rate behavior hitherto unacknowledged. We find that rates switch between alternative stationary regimes characterized by differing means, speeds of mean-reversion and volatility. For New Zealand, high rates of inflation increase the probability of remaining in a regime characterized by a faster speed of adjustment. Further application of this methodology considers the real interest rate differential between Australia and New Zealand and points to differing regimes based on volatility rather than persistence.     

Capital accumulation and real exchange rate behavior in a small open economy with credit market frictions

Summary. We consider the nature of the relationship between the real exchange rate and capital formation. We present a model of a small open economy that produces and consumes two goods, one tradable and one not. Domestic residents can borrow and lend abroad, and costly state verification (CSV) is a source of frictions in domestic credit markets. The real exchange rate matters for capital accumulation because it affects the␣potential for investors to provide internal finance, which mitigates the CSV problem. We demonstrate that the real exchange rate must monotonically approach its steady state level. However, capital accumulation need not be monotonic and real exchange rate appreciation can be associated with either a rising or a falling capital stock. The relationship between world financial market conditions and the real exchange rate is also investigated. Received: October 3, 1997; revised version: October 23, 1997     

The structure of wage-price determination and unemployment in a small open economy

Conclusions The main focus of this paper is the analysis of consequences of different hierarchies of wage determination in a simple two-sector model of a small open economy. Already from the preliminary discussion of some comparative static experiments in Section 2 of this paper it could be demonstrated that it can make a big difference whether wage leadership is taken over by the exposed or sheltered sector. In the long run this should be primarily a concern for advocates of fiscal policy measures. Remembering that fiscal policy by means of public expenditure increases (that means not tax cuts or transfer payments increases) primarily is concentrated in construction (in most countries a heavily sheltered business) it will depend on the hierarchy of wage determination between the two sectors whether or not the employment increase in the sheltered sector is crowding-out employment in the exposed sector. This type of crowding-out is not transmitted via higher rates of interest (which is kept constant in this model) but real wage increases in the sheltered sector.This paper is part of a research project on Shocks to Competitiveness and Economic Adjustment in Mature Industrial Economies financed by the Ford Foundation and coordinated by Sven Arndt, University of California, Santa Cruz.I am grateful to my discussant at the conference in Hernstein, Klaus Neusser, University of Vienna, who provided enough material for future improvements of this research.     

The dynamic effects of tax policies in a small open economy

We develop an intertemporal optimizing model of a small open economy with both durable and nondurable consumption to address the implications of alternative tax policies. An increase in lump sum taxes reduces the steady state level of consumption and improves the stock of foreign bonds. Consistent with empirical evidence, durable consumption exhibits initial excess volatility. Though an increase in the tax on durables increases the demand for nondurables and improves the bond holdings in the steady state, an increase in the tax on nondurables has insignificant effects on the stock of foreign bonds and the consumption of durables. Using quarterly data from the UK and estimating generalized impulse response functions we find empirical support. We also calibrate the welfare implications of different tax policies.     

GDP nowcasting: application and constraints in a small open developing economy

Despite data limitations, an attempt is made to find out if a GDP nowcasting model can provide reliable forecasts for a small open economy. Two competing Bayesian vector autoregressive models are tested rigorously to obtain the optimal model by minimizing in-sample forecasting errors. The main finding of this study is that GDP nowcasting can produce reliable results for a small open economy despite the unavailability of sufficient data sets and the lack of high frequency indicators.     

Monetary policy and credit cards: Evidence from a small open economy

This paper uses a unique monthly data set that covers the overall credit card usage in a small-open economy, Turkey, to investigate a possible credit channel of monetary policy transmission through credit cards. A reduced-form vector autoregression analysis is employed, where the forecast error variance decompositions are calculated for three-year windows over the period 2002–2009. It is shown that, during the recent financial crisis that has started in 2007, the monetary policy of Turkey has shifted toward focusing on output volatility and interest rate smoothing through setting short-term interest rates, while the inflation rate has been mostly affected by exchange rate movements and inflation inertia. Credit card usage has an increasing effect on inflation rates through time, requiring more policy emphasis on the credit channel through credit cards. When the effects of the credit view and the money view are compared, the former seems to be more effective on the real side of the economy, independent of the level of inflation.     

The optimal choice of monetary policy instruments in a small open economy

Abstract.  This paper studies how the nature of shocks affects the optimal choice of monetary policy instruments in a small open economy. Three classic rules, fixed exchange rates, monetary targeting, and inflation targeting are studied and ranked by comparing with the optimal monetary policy under commitment. We find that the ranking of the simple rules can be mapped to the terms-of-trade variability that the rule allows relative to what a particular shock optimally calls for. It turns out that inflation targeting dominates the other two rules under productivity or velocity shocks, whereas monetary targeting is the best performer under fiscal shocks.
