Currency diversification and export competitiveness: A model of the ‘Dutch disease’ in Egypt

The paper presents a dynamic portfolio model under currency inconvertibility which rationalizes the recent Egyptian experience of real exchange rate appreciation and currency diversification following the increase in oil exports and the partial financial liberalization that took place after 1976. The two shocks are linked because the relative price of manufacturing exports in terms of oil is also the premium of the ‘gray’ market rate over the official exchange rate. The effects of various official exchange rate policies on the temporary equilibrium values of the premium and the real wage and on the steady-state values of asset stocks are examined. A review of the Egyptian experience in light of the model results suggests that the unification of 1979 was ineffective against this variant of the ‘Dutch disease’ but that the restoration in 1981 of a parallel rate closer to the ‘gray’ market rate applicable to competitive exports may be more effective.     

Insulation properties of separating exchange markets

Insulation properties play an important role for countries in favour of separating rates for separating transactions. Such properties insulate the open economy from monetary and real shocks, of domestic and foreign origins. Through theoretical and numerical analyses, we find that in a unified flexible exchange rate system, portfolio holders' expectations drive the price adjustment, leading to expectations of exchange rate changes. In separating exchange markets, the financial rate reflects the instability of portfolio holders' expectations and capital flows; however, the real exchange rate and hence the macroeconomy is stable. Uncertainty of shocks ceases to affect the real sector of the economy.     

The changing nature of the real exchange rate: The role of central bank preferences

We investigate the sources of real exchange rate fluctuations. We do so, first, in the context of a DSGE model that explicitly considers the central bank's preferences. Then we estimate SVAR models, where shocks are identified by sign restrictions derived from the DSGE model. We perform this exercise for twelve countries, nine of which have adopted inflation targeting during the period analyzed. In sharp contrast to the previous evidence in the literature, we find that exchange rate (country risk premium) shocks have become the main drivers of real exchange rate dynamics, while real shocks play a less important role. Evidence from the DSGE model reveals that, as the central bank becomes more averse to inflation movements, and cares less about nominal exchange rate fluctuations, the impact of nominal shocks on the real exchange rate tends to increase, while the impact of real shocks decreases. Our results suggest that the adoption of inflation targeting, along with a floating exchange rate, contributes to a shift in the relative importance of demand and country risk premium shocks in determining the RER.     

Demand for money in Bangladesh: a cointegration analysis

The aim of this study is to estimate the demand for real broad (M2) money in Bangladesh using the most recently developed autoregressive distributed lag approach to cointegration analyses. The empirical results show that there is a unique cointegrated and stable long-run relationship among real per capita broad money demand, real per capita income, domestic interest rates and unofficial exchange rate (UM) premiums which act as a surrogate for foreign interest rates. With money as the dependent variable, the results show that the income and interest elasticities are positive while the UM premium elasticity is negative. These results suggest that distortions in the financial and foreign exchange markets should be reduced in order to increase financial saving or monetary accumulation. Our results also reveal that the demand for money in Bangladesh is stable despite the changes in financial and exchange rate policies between 1975 and 1995.     

Uncovering the link between a flexible exchange rate and fundamentals: the case of Central and Eastern European economies

This article examines the link between a nominal exchange rate and macrofundamentals in Central and Eastern European (CEE) countries. We use the model based on the monetary policy rule as a theoretical framework that explains the relations between the exchange rate and price level, risk premium, output gap, and expected inflation. It allows for endogeneity of the monetary policy – the issue ignored in the widely used monetary model. The sample covers the period January 2000 – December 2014, so the data are not plagued by high-inflation differentials characteristic for the early transition period and include countries with relatively flexible exchange rates. Our empirical strategy employs the panel error correction model that allows for cross-sectional dependence and a series of panel causality tests. The main finding is that the nominal exchange rates in CEE countries are not disconnected from macrofundamentals implied by the Taylor rule-based model. More specifically, we find that there is a strong cross-sectional dependence among CEE countries, exchange rates Granger-cause macrofundamentals and tend to revert to the long-run relation, and that the results are robust to the ‘extraordinary circumstances’ argument, i.e. do not rest on the dynamics during the global financial crisis.     

Multi‐product exporters,variable markups and exchange rate fluctuations

In this paper we investigate how firms adjust markups across products in response to fluctuations in the real exchange rate. We estimate markups at the market–product–plant level using detailed panel production and cost data from Mexican manufacturing between 1994 and 2007. Exploiting variation in the real exchange rate in the aftermath of the peso crisis in December 1994, we provide robust empirical evidence that plants increase their markups and producer prices in response to a real depreciation and that this increase is greater for products with higher productivity. Thus, we provide direct evidence for the theoretical mechanism of variable markup response behind incomplete and heterogeneous exchange rate pass‐through on producer prices. Our empirical methodology allows us to decompose the producer price response to exchange rate shocks into a markup and a marginal cost component using our markup estimates. Using these estimates, we establish that marginal cost at the product–plant level increases more in response to real exchange rate depreciation if the plant has higher share of imported inputs.     

Why does monetary policy respond to the real exchange rate in small open economies? A Bayesian perspective

To estimate how monetary policy works in small open economies, we build a dynamic stochastic general equilibrium model that incorporates the basic features of these economies. We conclude that the monetary policy in a group of small open economies (including Australia, Chile, Colombia, Peru, and New Zealand) is rather similar to that observed in closed economies. Our results also indicate, however, that there are strong differences due to the shocks from the international financial markets (mainly risk premium shocks). These differences explain most of the variability of the real exchange rate, which has important reallocation effects in the short run. Our results are consistent with an old idea from the Mundell–Fleming model: namely, a real depreciation to confront a risk premium shock is expansive or procyclical, in contradiction to the predictions of the balance sheet effect, the J curve effect, and the introduction of working capital into RBC models. In line with this last result, we have strong evidence that only in one of the five countries analyzed in this study does not intervene the real exchange rate, the case of New Zealand.     

“New” monetary policy instruments and exchange rate volatility

Turkish economy has been suffering from rises in financial flows since the last two decades that these flows have raised financial stability challenges across emerging economies including Turkey. Regarding the ability of the central banks to decrease the financial risks including volatile exchange rate, the Central Bank of the Republic of Turkey has designed and implemented a new policy mix. In this study, we investigated the effect of new policy instruments (IRC, RRR and ROM) on the volatilities of US dollar, euro, British pound and basket rate for Turkish economy between January 2, 2002 and December 9, 2014 by using ARMA-GARCH, ARMA-EGARCH and SWARCH models. From the estimation results, we could not reach enough evidence that the IRC and RRR instruments could decrease the volatilities of exchange rates under investigation while the ROM instrument was successful, especially on US dollar and basket rate. We also found strong evidence in favour of asymmetric volatility, indicating that the positive shocks led to greater exchange rate volatility than negative ones.     

The Volatility of Real Exchange Rates: The Australian Case

This paper presents an empirical investigation into factors underlying the real U.S.-Australian dollar exchange rate. We find that the random walk model of the real exchange rate can be improved by various GARCH specifications. In particular, we find that the estimated risk premium from a GARCH-M model is not robust to model specification. When the model is extended to include the $US/Yen real exchange rate and an index of commodity prices the GARCH-in-mean term is no longer significant. The additional variables seem to account for the increased volatility of the real exchange rate in the post-1983 period. Somewhat surprisingly, we find that changes in the Australian term spread and US-Australian interest rate differential have little or no explanatory power for the real exchange rate.     

Financial Deregulation And The Relationship Between The Economy And The Share Market In Australia

In this paper we investigate the effect of financial deregulation on the relationship between the macro-economy and the share market within the framework of a VAR using quarterly Australian data for four variables – aggregate share prices, real output, the term premium and the default premium. After an analysis of stationarity and cointegration of the variables, we specify the VAR in the first differences of the logs of share prices and output and the levels of the premia. We identify December 1983 as the most appropriate date for testing for a structural break in our model due to financial deregulation and find strong evidence supporting our hypothesis of a break at this date. We go on to estimate and simulate the model separately over two sub-samples: 1978(1)–1983(4) and 1984(1)–2001(2). While our results are not clear-cut, we find that, if anything, the deregulation of financial markets weakened the relationship between the share market and the rest of the economy.     

UNEMPLOYMENT PERSISTENCE AND THE SUSTAINABILITY OF EXCHANGE RATE PEGS

It is commonly thought that an open economy can accommodate output shocks through either exchange rate or real sector adjustments. We formalize this notion by incorporating unemployment persistence into a two‐sided escape clause model of currency crises. We show that unemployment persistence makes a currency peg more fragile and undermines the credibility of the monetary authority in a dynamic setting. The fragility is captured by a devaluation premium in expectations that increases the average inflation rate when the currency peg is more vulnerable to ‘busts’ than ‘booms’. This interaction between macroeconomic and microeconomic rigidities suggests that a policy reform can only be consistent if it renders either exchange rates or the economy more flexible.     

CAN FINANCING CONSTRAINTS EXPLAIN THE ASSET PRICING PUZZLES IN PRODUCTION ECONOMIES?*

General Equilibrium asset pricing models have a difficult time simultaneously delivering a sizable equity premium, a low and counter cyclical real risk free rate, and cyclical variation in return volatility. To explain these stylized facts, this article introduces occasionally binding financing constraints that impede producers’ ability to invest. The financial frictions drive a wedge between the marginal rate of substitution and firms’ internal stochastic discount factors so that the shadow value of capital is not tied to the average price of capital. The model delivers higher and more volatile asset returns during recessions as well as a counter cyclical equity premium.     

A MACROECONOMIC PERSPECTIVE ON SKILL SHORTAGES AND THE SKILL PREMIUM IN NEW ZEALAND*

Qualification and occupation‐based measures of skilled labour are constructed to explain the skill premium – the wage of skilled labour relative to unskilled labour in New Zealand. The data exhibit a more rapid growth in the supply of skilled labour than the skill premium, and a very large increase in the real minimum wage over the period from 1986 to 2005. We estimate the rate of increase in the relative demand for skills and the elasticity of substitution. The data are consistent with skill shortages and a skill‐bias technical change. We examine the effects of the minimum wage, capital complementarity, and the exchange rate on the skill premium. We also test whether the demand for skills and the elasticity of substitution varied across industries and over time.     

Evidence on the sectoral monetary transmission process under a fixed exchange rate regime

Traditional macroeconomic models suggest that monetary policy changes are largely ineffective in fixed exchange rate economies. However, Edwards and Végh (1997) present a model that shows this might not be the case, as a tightening in monetary policy raises financial costs faced by firms and therefore lowers real wages and, by extension, consumption. This paper empirically tests this hypothesis using data on a country with one of the longest running fixed exchange rate regimes (1975–present). The results of the study confirm the theoretical predictions of Edwards and Végh, but they also show that the propagation of nominal shocks in fixed exchange rate systems is comparatively slower than in countries with a more flexible exchange rate regime.     

Real exchange rate dynamics: Relative importance of Taylor‐rule fundamentals,monetary policy shocks,and risk‐premium shocks

We first show that the solution to the real exchange rate under the Taylor rule with interest rate smoothing can have two alternative representations—one based on a first‐order difference equation and the other based on a second‐order difference equation. Then, by comparing error terms from these two alternative representations and analyzing their second moments, we evaluate the relative importance of Taylor‐rule fundamentals, monetary policy shocks, and risk‐premium shocks in the dynamics of the real exchange rate. Empirical results suggest that the risk‐premium shock is the largest contributor to real exchange rate movements for all the countries examined, with the Taylor‐rule fundamentals and monetary policy shocks playing a limited role. These results are robust to various alternative sets of parameter values considered for the Taylor rule with interest rate smoothing.     

Capital in the Twenty-First Century: Reinterpreting the fundamental contradiction of capitalism

At a theoretical level this article discusses Piketty’s hypothesis that the distribution of income and wealth tends to become more concentrated over time when the rate of return on capital is greater than the growth rate of real output. We develop a post Keynesian model of growth and distribution showing that once capital is differentiated from wealth, the increase in income and wealth concentration actually occurs when the rate of valorization of financial and real estate assets is greater than the growth rate of real output, and that this situation may be triggered by financial liberalization.     

Measuring exchange rate misalignment in Turkey

Turkey has embarked an extensive dis-inflation and stabilization program in December 1999. The programme exclusively relied on a nominally pegged (anchored) exchange rate system for dis-inflation and on fiscal austerity. In February 2001, however, Turkey experienced a severe financial crisis which necessiated the dismantling of the exchange rate anchor and a switch to a regime of free float.

This article proposes a new methodology to measure exchange rate misalignment for Turkey over the period January 1992 to December 2001. In a single equation framework, the model estimates the real exchange rate within a time varying parameter model, where a return-to-normality assumption about the parameters is assumed. Contrary to common belief, it is found that, except the initial four months of the stabilization programme, the Turkish lira remained undervalued for most of 2000. Also, one observes a pattern where the lira has been overvalued after the financial crisis of 1994 until 1998, and has displayed a tendency of undervaluation after then.     

Determinants of the real exchange rate in the long-run for developing and emerging countries: a theoretical and empirical approach

This paper presents a new framework for the determinants of real exchange in the long-run in developing and emerging countries (DECs). We assume that currencies should be regarded as an asset. In consequence, dealers in the foreign exchange market play a crucial role on its dynamics. To set our model, we connect the model developed by Kaltenbrunner, which is grounded on chapter 17 of the General Theory, with productivity’s differential effect. By doing so, it states that even short-run factors and monetary variables affect the long-run real exchange rate. Moreover, it points out that the hierarchical nature of the international monetary system is crucial to understand exchange rate movements in DECs. Besides presenting such theoretical approach, our contribution is to test it empirically for 45 DECs from 1990 to 2008 by applying econometric techniques appropriate for panel data. We use a new data-set, which comprises, among other variables, foreign portfolio flow, interest rate differential, external vulnerability measures, and international liquidity, on annual basis. The empirical results endorse this framework. Overall, it shows the primacy of financial factors as determinants of the long-run real exchange rate and points to the endogenous and self-perpetuating nature of international monetary system hierarchy.     

Understanding Exchange Rate Movements during the 2008 Financial Crisis

During the 2008 financial crisis, many advanced economies, whose banking systems suffered significant capital losses, experienced large and rapid exchange rate depreciations followed by prolonged and gradual appreciation in subsequent periods. In order to understand one possible explanation of these observed exchange rate movements, we develop a simple model of a highly leveraged banking sector in which banks obtain part of their funding from abroad. A fall in bank net worth leads to foreign lenders demanding a higher risk premium on credit supplied to domestic banks. This higher risk premium can be met if the exchange rate experiences an appreciation along the adjustment path, since this raises the value of the bank's earnings in terms of the foreign currency for every period that the foreign risk premium is elevated. In order for the exchange rate to appreciate by a large amount along the adjustment path, it must initially become undervalued – relative to its long-run level – so that in equilibrium the market is willing to bid up its value in subsequent periods. This thus gives rise to the large initial depreciation of the exchange rate followed by its prolonged and gradual appreciation.     

Firm Market Performance and Volatility in a National Real Estate Sector

We present empirical evidence using daily data for stock prices for 17 real estate companies traded in the Sao Paulo, Brazil stock exchange, from August 26, 2006 to March 31, 2010. We use the U.S. house price bubble, financial crisis and risk measures to instrument for momentums and reversals in the domestic real estate sector. We find evidence of conditional premium persistence and conditional volatility persistence in the market. We find that the conditional risk-return relationship in the sector is consistent with the prospect theory of risk attitudes in this period. Certain companies seem to be operating on a perceived potential industry return above the target, while most others are below the target, and the whole sector is below target on average.
