Revisiting the exchange rate disconnect puzzle

One of the major anomalies in International Macroeconomics is the persistent finding that the exchange rate has no empirical relationship with a variety of macroeconomic fundamentals. Dubbed the ‘exchange rate disconnect puzzle’, this article examines this issue for five Australian dollar bilateral exchange rates, using quarterly data for the period 1984:1–2015:4. A novel feature of this article is that it departs from the extant literature by using a different approach to testing for cointegration. The results show that the exchange rates and fundamentals move together in the long run. Furthermore, the results show that fundamentals Granger cause exchange rates, both in the short run and the long run.     

Outbound Business Travel Depends on Business Returns: Australian Evidence

In an earlier note, Collins and Tisdell (2002b ) explored the possibility of a long-run relationship between Australian business returns and international business travel. Using annual data they found that such a relationship exists. The purpose of this study is to further examine this relationship using quarterly data for the time frame 1974:1 to 1999:4. In addition, previous studies on international business travel have offered some but not strong evidence for the existence of a positive relationship between the level of international business travel and real GDP of the origin country. This study suggests that the aggregate return on business investments is a better predictor of international business travel than GDP. The Engle-Granger and Johansen's maximum-likelihood cointegration procedures are used to show a long-term relationship exists between Australian outbound business travel and Australian business returns, but not with Real Australian GDP. Reasons for this relationship are discussed.     

Covered Interest Parity and Speculative Efficiency: Some Empirical Evidence for Australia*

Two key relationships which feature prominently through out modern international monetary theory are: (i) covered interest parity and(ii) speculative efficiency of the foreign exchange market, i.e., the unbiasedness of the forward rate as a predictor of the spot rate. This paper presents some empirical evidence for these two hypotheses using Australian data over the period September 1974 to December 1981 during which the Australian dollar was essentially floating. Both quarterly and overlapping monthly data are used. The results obtained generally provide some support for the two hypotheses.     

The missing shock: the macroeconomic impact of British Privatizations

In this paper the impact of privatization on macroeconomic performance in the United Kingdom is tested using quarterly data from 1979 to 1999. Privatization proceeds have been included in a simple analytical framework dealing with both demand and supply-side of the economy. Multivariate cointegration techniques have been used in order to consider the nonstationarity of the time series involved. The empirical results show that privatizations have no long-run effects on output in the UK. This result is consistent with microeconomic evidence that shows that in the UK ownership change per se had little impact on long term productivity trends. Moreover it is found that privatization proceeds have contributed to sustaining public expenditures.     

The Interdependence of Australian and Foreign Real Interest Rates

We assess the interdependence of the Australian and foreign (USA, Japan, UK, Canada, Germany, NZ) short-term real rates of interest using a quarterly time series: 1970(1) to 1997(4). Applying Zivot and Andrews (1992) tests for stationarity subject to structural breaks we find all series to be 1(1). Structural breaks occurring in each series at different times are explained by policy changes, institutional characteristics or shocks such as the second oil crisis. Conventional bivariate cointegration tests (without breaks) provide limited evidence of interdependence, however using the Gregory Hansen (1996a,b) technique it is clear that foreign and Australian rates are interrelated once structural breaks are accommodated. Multivariate cointegration and error correction modelling confirm this finding. Policy implications are indicated.     

Real exchange rates and real interest rates once again: a multivariate panel cointegration analysis

This paper employs multivariate panel cointegration techniques to re-examine the empirical relationship between bilateral real exchange rates and real interest rates. The results from a panel of 1470 quarterly observations on Canada, France, Germany, Italy, Japan, UK, and USA over the period 1977 to 1994 indicate the absence of any long-run relationship between the two variables.     

Mortgage‐Backed Securities (MBS): Is It a Curse or a Blessing for the Australian Home Loan Market? A Natural Experiment

The Australian home loan market has seen a significant and persistent boom over more than two decades. The extant literature exploring the underlying factors explaining this boom has predominantly looked at the demand side rather than the supply side. In this paper, we look at a major supply‐side issue, the introduction of mortgage‐backed securities and its likely impact on the home loan market. In doing so, we have developed a mathematical model that theorises this likely relationship. Our mathematical model predicts possible existence of an unstable equilibrium in the home loan market in the presence of mortgage‐backed securities. We have subsequently backed up our theoretical exercise with sound empirical evidence acquired and analysed as a natural experiment in the Australian scenario using quarterly market data on home loans and mortgage‐backed securities data for a 36‐year period from 1976 to 2012. Using unknown structural break tests, we have identified significant breaks around late 1992 to mid‐1995, clearly indicating that there were significant changes in the housing market due to the introduction of mortgage‐backed securities in early 1993. We have also performed a stability test confirming that under certain conditions this market can become unstable.     

Consumption multipliers of different types of public spending: a structural vector error correction analysis for the UK

The aim of this paper is to investigate the relationship between government spending and private consumption in the UK, for which there is scarce previous empirical evidence. We disaggregate public expenditure into three categories and search for the corresponding private consumption multipliers. Our analysis is based on the estimation of a structural vector error correction model with quarterly non-interpolated data for the period 1981:1–2007:4. Initially, we estimate negative but barely significant effects on consumption of shocks to total public spending. Then, using the public spending breaking down, we find that while shocks to public wages crowd-out private consumption as predicted by neoclassical models, shocks to the non-systematic component of social spending and government purchases of goods and services generate a positive reaction, so to crowd-in private consumption. Thus, the qualitative and quantitative dimensions of fiscal multipliers on private consumption change across different public spending categories. Our findings suggest that any empirical support of competing theoretical models on the issue would benefit from a disaggregation of government expenditure, rather than focusing on the aggregate measure.     

Fractional cointegration,low frequency dynamics and long-run purchasing power parity: an analysis of the Australian dollar over its recent float

A relatively new but generalized concept of fractional cointegration is applied to shed some light on the validity of purchasing power parity (PPP) as a long-run equilibrium condition, by examining the long-run relationship between quarterly consumer price indices and bilateral exchange rates of the Australian dollar and seven major OECD trading partners, over Australia's recent float. The paper demonstrates that relaxing the condition that the residual from the cointegration equation must be a I(0) process, provides a wide range of cases of parity-reversion with processes that are CI(1,d) with 0 < d < 1. Findings tend to suggest that, while standard tests of cointegration fail to support cointegration between nominal exchange rates, domestic and foreign prices, and thus the empirical favour for PPP as a long-run phenomenon, the fractional cointegration analysis permits deviations from equilibrium to follow a fractionally integrated process and hence captures a much wider class of parity or mean-reversion behaviour. Results are mainly supportive of long-run PPP. Furthermore, an analysis of the short-run dynamics propelling the long-run relationship (through a VECM) reveals that domestic prices are consistently the initial receptor of an exogenous shock to the equilibrium and the long-run equilibrium is restored through the short-run adjustment of the nominal exchange rates. These findings are shown to hold clear policy implications.     

Permanent prices,expected price changes,and the demand for money

This paper investigates the empirical validity of the distinction between measured and permanent prices for cash balance decisions. The use of permanent prices has been advocated by Friedman over twenty five years ago, but the idea has received little attention in the literature. Using Canadian quarterly data, we find that the permanent price hypothesis yields meaningful estimates of the demand for money, but it does not appear to contribute significantly to our understanding of cash balance decisions. A number of assumptions about the relationship between the elasticities of income, price, and price change expectations are tested as well.     

Inflation,money, interest rate,exchange rate,and casuality: the case of Egypt,Morocco, and Tunisia

This study provides further evidence of the inflationary efects of the rates of growth of money supply, gross domestic product, efective exchange rate, and imported inflation for Egypt, Morocco, and Tunisia using quarterly data from 1964 to 1990. In addition, it examines the Granger causality between inflation and money supply as well as between inflation and the real exchange rate in the countries under consideration. Most of the results are consistent with extant theory and empirical evidence.     

Revisiting the interest rate–exchange rate nexus: a Markov-switching approach

In this paper the interest rate–exchange rate nexus and the effectiveness of an interest rate defense are investigated empirically. I present a reduced form evidence which characterizes the empirical relationship between interest rates and exchange rates. I use a Markov-switching specification of the nominal exchange rate with time-varying transition probabilities. Empirical evidence from six developing countries: Indonesia, South Korea, the Philippines, Thailand, Mexico, and Turkey indicates that raising nominal interest rates leads to a higher probability of switching to a crisis regime. Thus, the empirical results presented here may support the view that a high interest rate policy is unable to defend the exchange rate. Unlike other studies which consider linear models only, my findings are robust and consistent over different countries and crisis episodes (Asian 1997 crises, Mexico 1994 crisis, and Turkey 1994, 2001 crises). In order to explain the empirical findings, I construct a simple theoretical model by incorporating an interest rate rule in the model proposed by Jeanne and Rose (2002) [Jeanne, O., Rose, A.K., 2002. Noise trading and exchange rate regimes, Quarterly Journal of Economics. 117 (2) 537–569]. The model has multiple equilibria, and under plausible conditions, higher exchange rate volatility is associated with higher interest rates.     

Macroeconomic Volatility and the Current Account: Evidence from a Panel of OECD Countries

ABSTRACT

This paper investigates the relationship between macroeconomic volatility and the current account. Using quarterly data for a panel of OECD economies, time-varying relative volatility measures are constructed for GDP, net output, and government consumption. The empirical evidence suggests that current account balances are positively affected by all three volatility measures. Moreover, the current account balance is found to be related positively to output growth and negatively to the growth of government consumption. Evidence from saving and investment rates also suggests that the precautionary saving motive is part of (though perhaps not the entire) mechanism that relates output volatility and the current account. Broadly consistent with the predictions of the standard theoretical model, these estimates are sizable, statistically significant, and robust.     

Gains from commitment in monetary policy: Implications of the cost channel

Many empirical studies find robust evidence that marginal cost of production directly depends on the nominal rate of interest. This relationship induces a cost channel for monetary policy transmission. Although the empirical literature provides ample evidence for a cost channel, studies that evaluate the welfare gains from monetary policy commitment have so far entirely ignored its presence. This study shows that, overlooking the cost channel, one significantly underestimates the welfare gains from monetary policy commitment. I find that there is a robust positive relationship between the size of the cost channel and welfare gains from monetary policy commitment. Using a version of the new Keynesian model calibrated to the US economy, I find that failure to take into account the presence of a cost channel leads to an understatement of the gains from monetary policy commitment by an amount equivalent to a 0.48 percentage points permanent cut in quarterly inflation.     

Nonlinear interest rate reaction functions for the UK

We empirically analyze Taylor-type equations for short-term interest rates in the United Kingdom using quarterly data from 1970Q1 to 2006Q2. Starting from strong evidence against a simple linear Taylor rule, we model nonlinearities using logistic smooth transition regression (LSTR) models. The LSTR models with time-varying parameters consistently track actual interest rate movements better than a linear model with constant parameters. Our preferred LSTR model uses lagged interest rates as a transition variable and suggests that in times of recessions the Bank of England puts more weight on the output gap and less so on inflation. A reverse pattern is observed in non-recession periods. Parameters of the model change less frequently after 1992, when an inflation target range was announced. We conclude that for the analysis of historical monetary policy, the LSTR approach is a viable alternative to linear reaction functions.     

A note on capacity utilization,productivity, and the Canadian output gap

This study revises estimates of real Canadian potential output and the real GNP gap by applying a method of directly estimating the actual and potential factor utilization rates to quarterly Canadian data. The empirical results indicate that capital utilization varies just under twice as much as labour use over the cycle. The results also suggest that labour productivity will vary procyclically, with the elasticity of productivity with respect to the employment rate estimated to be 1.42.     

SOME EVIDENCE ON MEAN REVERSION IN EX ANTE REAL INTEREST RATES

Ex ante real interest rates and their differentials are tested for mean reversion using quarterly data on three-month treasury bill rates and consumer prices for 12 major industrial countries over the period 1972:l-1993:3. The results are strongly supportive of mean reversion, particularly when less conventional tests are employed. The conclusion that can be derived from the empirical evidence is that goods, capital and foreign exchange markets have become highly integrated in the countries under consideration.     

The order of integration for quarterly macroeconomic time series: A simple testing strategy

An empirical example and a simulation study show that much more attention should be devoted to the practical issue of selecting the maximum admissible order of integration for quarterly macroeconomic time series. In fact, it is shown that when that order is too high, one may get (spurious) evidence for an excessive number of unit roots, resulting in an overdifferenced series. Besides introducing a simple and intuitive definition for the order of integration of quarterly time series, this paper also presents a simple testing strategy to determine that order for the case of macroeconomic data.Helpful comments and suggestions from João Santos Silva and Paulo Rodrigues are gratefully acknowledged.

Assessing the causal relationship between euro-area money and prices in a time-varying environment

The paper provides new evidence on the causal relationship between money and price for the euro area using quarterly data for the period 1980 to 2006, employing two alternative methods of estimation: the vector error correction (VEC) and time-varying coefficient (TVC) estimation techniques. The latter technique has the advantage over the former technique in that it can deal with possible specification biases and spurious relationships that may have arisen from structural changes. The empirical results from the VEC method reveal a bidirectional causal relationship between money and prices. The results from the TVC technique suggest that money is acting as an exogenous process determining the price level.     

Financial development and economic growth in Australia: An empirical analysis

The paper empirically examines the dynamic relationship between financial development and economic growth in Australia in terms of bank-based and market-based financial structure. A time-series approach using the VAR Model is used to provide evidence for the dynamic relationship. The paper provides empirical evidence on the causal impact of the financial market on the economic growth of the Australian economy. The results suggest that financial intermediaries and financial markets have different impacts on economic growth given their diverse roles in the domestic economy. In particular there is evidence of causality from economic growth to the development of the financial intermediaries. On the other hand, development in the financial markets causes economic growth but there is no evidence of any causality from economic growth to financial markets. The sensitivity test using different interest rates does not change the results.I Jel classification: O16, G18, G28I We would like to thank Tilak Abeysinghe and Rajagurn Gunasekaran for their helpful comments on the first draft.
