What is behind the real appreciation of the accession countries’ currencies?: An investigation of the PPI-based real exchange rate

In the paper, we calculate real equilibrium exchange rates (EER) for EU accession countries and compare these with the actual exchange rate movements since the mid-1990s. The real equilibrium exchange rates are derived from models of macroeconomic balance and tested for econometrically. It is found that productivity increases can be regarded as one source of the observed PPI-based real appreciation of the accession countries’ currencies. These productivity gains experienced in the process of economic catch-up imply an increased capacity to produce high-quality export goods and are a key driving force of exports. To a large extent real appreciation can, therefore, be viewed as an equilibrium phenomenon.     

Pricing‐to‐Market and Market Structure*

Stimulated by imperfect competition/sticky prices framework of the new open economy macroeconomics, empirical research has reconsidered the role of exchange rates in international adjustment. This paper reassesses the link between exchange rates and traded good prices by estimating pricing‐to‐market equations for the five main euro area countries over the period 1990–99. We minimize selection biases by keeping all manufacturing products and all destination markets and show that exchange rate pass‐through (ERPT) is much larger, almost complete, than previously estimated. Thanks to a huge variability in terms of exchange rate variations, products and destination markets, we can map differences in ERPT into market structures and, at the same time, reconcile our results with the empirical literature. We find that ERPT is highly incomplete for sales by oligopolistic industries into advanced economies, indeed in the order of 50–60% as previously estimated. ERPT is instead almost complete in emerging and developing economies where therefore exchange rate movements can help adjust external imbalances. We also find that ERPT is largely asymmetric: it is almost complete after an appreciation of the exporter's currency, rather incomplete after a depreciation. This result is very robust across specifications.     

Model‐free evaluation of directional predictability in foreign exchange markets

We examine directional predictability in foreign exchange markets using a model‐free statistical evaluation procedure. Based on a sample of foreign exchange spot rates and futures prices in six major currencies, we document strong evidence that the directions of foreign exchange returns are predictable not only by the past history of foreign exchange returns, but also the past history of interest rate differentials, suggesting that the latter can be a useful predictor of the directions of future foreign exchange rates. This evidence becomes stronger when the direction of larger changes is considered. We further document that despite the weak conditional mean dynamics of foreign exchange returns, directional predictability can be explained by strong dependence derived from higher‐order conditional moments such as the volatility, skewness and kurtosis of past foreign exchange returns. Moreover, the conditional mean dynamics of interest rate differentials contributes significantly to directional predictability. We also examine the co‐movements between two foreign exchange rates, particularly the co‐movements of joint large changes. There exists strong evidence that the directions of joint changes are predictable using past foreign exchange returns and interest rate differentials. Furthermore, both individual currency returns and interest rate differentials are also useful in predicting the directions of joint changes. Several sources can explain this directional predictability of joint changes, including the level and volatility of underlying currency returns. Copyright © 2007 John Wiley & Sons, Ltd.     

Evaluating New‐Keynesian Models of a Small Open Economy*

We suggest a strategy to evaluate members of a class of New‐Keynesian models of a small open economy. As an example, we estimate a modified version of the model in Svensson [Journal of International Economics (2000) Vol. 50, pp. 155–183] and compare its impulse response and variance decomposition functions with those a structural vector autoregression (VAR) model. The focus is on responses to foreign rather than to domestic shocks, which facilitates identification. Some results are that US shocks account for large shares of the variance of Canadian variables, that little of this influence is due to real exchange rate movements, and that Canadian monetary policy is not adequately described by a Taylor rule.     

The exchange rate and machinery and equipment imports: Identifying the impact of import source and export destination country currency valuation changes

This paper presents estimates of the impact of exchange rate movements on the quantity of machinery and equipment imports. Many countries have become increasingly reliant on imports of these types of products and evidence in a number of studies indicates that investment in machinery and equipment contributes to improved productivity and growth. Unlike previous studies, this study differentiates between exchange rate movements with respect to machinery and equipment import source and final good export destination countries. Data are employed for two machinery and equipment importing countries, Australia and Canada, and two exporting countries, Japan and the U.S. The results indicate that a currency depreciation with respect to an import source country has a significant negative effect on the quantity of machinery and equipment imports, while a depreciation with respect to a domestic final good export destination country has a significant positive effect. These findings imply that the net impact on the quantity of machinery and equipment imports of an exchange rate change with respect to a particular country will depend on the extent to which that country is a supplier of machinery and equipment imports and a market for domestic exports.     

Sources of real exchange rate movements in Saudi Arabia

The paper investigates the sources of real exchange rate movements in Saudi Arabia by decomposing real exchange rate movements into those attributable to real and nominal shocks. Using a popular structural VAR model and assuming long-run neutrality of nominal shocks, we find that real shocks play a significant role in explaining real exchange rate movements in Saudi Arabia. Using a more disaggregated model, we also find that oil production shocks rather than real oil price shocks are responsible for real exchange rate movements. In order to stabilize the real exchange rate, Saudi Arabia should focus on stabilizing oil production.(JEL F3, C5)     

Further Evidence on PPP Adjustment Speeds: the Case of Effective Real Exchange Rates and the EMS*

Two different approaches intend to resolve the ‘puzzling’ slow convergence to purchasing power parity (PPP) reported in the literature [see Rogoff (1996) , Journal of Economic Literature, Vol. 34.] On the one hand, there are models that consider a non‐linear adjustment of real exchange rate to PPP induced by transaction costs. Such costs imply the presence of a certain transaction band where adjustment is too costly to be undertaken. On the other hand, there are models that relax the ‘classical’ PPP assumption of constant equilibrium real exchange rates. A prominent theory put together by Balassa (1964, Journal of Political Economy, Vol. 72) and Samuelson (1964 Review of Economics and Statistics, Vol. 46) , the BS effect, suggests that a non‐constant real exchange rate equilibrium is induced by different productivity growth rates between countries. This paper reconciles those two approaches by considering an exponential smooth transition‐in‐deviation non‐linear adjustment mechanism towards non‐constant equilibrium real exchange rates within the EMS (European Monetary System) and effective rates. The equilibrium is proxied, in a theoretically appealing manner, using deterministic trends and the relative price of non‐tradables to proxy for BS effects. The empirical results provide further support for the hypothesis that real exchange rates are well described by symmetric, nonlinear processes. Furthermore, the half‐life of shocks in such models is found to be dramatically shorter than that obtained in linear models.     

The effects of dollar appreciation on sectoral labor market adjustments: Theory and evidence

We examine the extent to which exchange rate fluctuations affect sectoral employment and wages in the United States. We introduce a theoretical rational expectation model that decomposes movements in the exchange rate into anticipated and unanticipated components. The model demonstrates the effects of demand and supply channels on the response of the nominal wage and labor employment to changes in the exchange rate. The evidence indicates that the deflationary effect dominates on industrial nominal wage in manufacturing and transportation industries in the face of dollar appreciation. More importantly, there is evidence of a decrease in employment growth in several industries in response to dollar appreciation, which is statistically significant in construction and at the aggregate level. This evidence is consistent with a decrease in labor demand given the loss of competitiveness of U.S. products following dollar appreciation. There are negative effects of dollar appreciation on labor market conditions in the United States. Nonetheless, dollar appreciation is consistent with an increase in employment growth in the mining sector where the share of imports is the largest among U.S. industries.     

Monetary Targets and the World Economy: A Progress Report

The recent changes in the value of the dollar and the talk of an interest rate ‘war’ demonstrate again that the world finds it difficult to cope with rapid exchange rate movements. In some ways the experience - and the reactions to it - are similar to the events of 1978. As now, the world was in a recession (though on a milder scale) and there were fears that exchange rate problems would obstruct economic recovery. The main difference is that in 1978 it was the strength of the Deutschmark which caused concern whereas this time the problems are associated with the rise in the value of the dollar. In a Briefing Paper in Economic Outlook, February 1978, ‘Monetary Targets and the World Economy’ we suggested that the problem arose from inconsistencies between national monetary policies and exchange rate objectives. In general, countries dislike exchange rate changes - in either direction - and there were problems because countries would not accept the exchange rate consequences of their own or other countries' monetary policies. We estimated the required monetary policies for stable exchange rates and suggested specific national monetary targets for 1978 which would at least move the world economy towards consistent monetary policies. In this Economic Viewpoint we return to those ideas. We consider what happened in 1978 and we also revise the underlying monetary rules. More recent experience suggests that although there has been some progress towards the convergence of monetary policies there will continue to be trend changes in exchange rates. It is also clear that there will be short-term fluctuations around these trends. We believe that greater convergence of monetary policies would be desirable but failing that it is important that countries should avoid abrupt changes in monetary policy. It is also important that countries should become accustomed to exchange rate changes. They should direct monetary policy towards their objectives for inflation and should not be diverted from it by temporary or permanent changes in their exchange rates.     

Technology,Labour Characteristics and Wage‐productivity Gaps*

We use plant‐level employer–employee data in production functions and wage equations to examine whether wages are based on productivity. We use a stepwise procedure to find out how the results are influenced by the kind of data that is available. The models include shares of employee groups based on age, level and field of education, and sex. The gap between the age‐related wage and productivity effects increases with age. Education increases productivity, but wage under‐compensates productivity especially for those with the highest level of non‐technical education. For women the results depend greatly on the specification and method used.     

Monetary integration in the Southern Cone

The effect of exchange-rate volatility on the domestic economy depends in part on the importance of trade in total economic activity. Unlike the European Union (EU), trade among the Mercosur countries is less highly integrated, so that movements in intra-area exchange rates are less important than exchange rates vis-à-vis the dollar and the euro. This paper analyzes the impact of exchange-rate and interest-rate volatility on investment and labor markets in the Southern Cone and finds that both volatility against the dollar and the euro and variability of interest rates have significant dampening effects on employment and investment.     

How well is productivity being priced?

By understanding how productivity shocks affect firm value, an entrepreneur can better compute the risk premium associated with uncertainty in production. This study explores the link between plant-level productivity and firm value for the baking and confectionary sector. From the impulse response analysis, the study finds that there is a lag in the firm’s response to productivity shocks at the plant level. Further, the paper employs Tobin’s Q as a valuation metric that acts as a link between a firm’s manufacturing plant productivity and firm value. Empirical estimations indicate that there is comovement between firm valuation and plant level productivity.     

MULTIPLE TESTING AND HETEROGENEOUS TREATMENT EFFECTS: RE‐EVALUATING THE EFFECT OF PROGRESA ON SCHOOL ENROLLMENT

The effect of a program or treatment may vary according to observed characteristics. In such a setting, it may not only be of interest to determine whether the program or treatment has an effect on some sub‐population defined by these observed characteristics, but also to determine for which sub‐populations, if any, there is an effect. This paper treats this problem as a multiple testing problem in which each null hypothesis in the family of null hypotheses specifies whether the program has an effect on the outcome of interest for a particular sub‐population. We develop our methodology in the context of PROGRESA, a large‐scale poverty‐reduction program in Mexico. In our application, the outcome of interest is the school enrollment rate and the sub‐populations are defined by gender and highest grade completed. Under weak assumptions, the testing procedure we construct controls the familywise error rate—the probability of even one false rejection—in finite samples. Similar to earlier studies, we find that the program has a significant effect on the school enrollment rate, but only for a much smaller number of sub‐populations when compared to results that do not adjust for multiple testing.

Firm Productivity and the Foreign‐Market Entry Decision

We use Japanese firm‐level data to examine how a firm’s productivity affects its foreign‐market entry strategy. The firm faces a choice between exporting and foreign direct investment (FDI). In the case of FDI, the firm has two options: greenfield investment or acquisition of an existing plant (M&A). If it selects greenfield investment, it has two ownership choices: whole ownership or a joint venture with a local company. Controlling for industry‐ and country‐specific characteristics, we find that the more productive a firm is, the more likely it is to choose FDI rather than exporting and greenfield investment rather than M&A.     

Decentralized environmental regulations and plant‐level productivity

Using the framework provided by the Porter hypothesis, we study the impact of environmental regulations and enforcement policies on plant‐level green total factor productivity (TFP) growth and its components related to efficiency change and technical change. The detailed microdata we use are from Sweden and for the pulp and paper industry. This industry is the source of significant amounts of water and air pollution and is one of the most heavily environmentally regulated manufacturing industries. Sweden has a unique decentralized regulatory structure where the manufacturing plants have to comply with plant‐specific regulatory standards stipulated at the national level, as well as decentralized local supervision and enforcement. Our empirical results point to beneficial impacts of the environmental policies on plants' green TFP growth and sustainable production practices. We also find that political economy considerations are important, as the presence of the Green Party and aspects like plant size (with corresponding local and regional economic effects) matter in enforcement of the standards.     

Effort reduction of employer‐to‐employer changers: Empirical evidence from football

We investigate changes in effort investment of employees who still fulfill a contract with their current employer but already signed a follow‐up contract with a new employer (employer‐to‐employer change). Because effort and outside contract assignments are hard to measure in firms, we use running data from professional football (n = 26,577) to proxy effort decisions. Fixed effect regressions reveal a statistically significant but weak reduction in a player's effort after signing a follow‐up contract with a new club. Because we find a statistically significant effort reduction in public sports, this effect might be even larger in less transparent labor markets.

The real exchange rate and the structure of aggregate production

This paper proposes a new, production theory approach to the determination of the real exchange rate, which is defined as the relative price of traded to nontraded goods as is common in the international trade literature. Using a Translog real GDI function that describes the aggregate technology of an open economy as a starting point, the real exchange rate can be formally derived as a function of domestic excess savings, the terms of trade, relative factor endowments and technological progress. Empirical results for Switzerland suggest that the main drivers of the real exchange rate are the terms of trade, followed by relative factor endowments. Contrary to conventional wisdom, the Balassa-Samuelson effect does not seem to play a significant role in explaining the long-term real appreciation of the Swiss franc.     

Race,Self‐Employment,and Labor Absorption

Past studies have argued that in the large cities of developing societies, unemployment is often alleviated when displaced workers are absorbed into the small‐scale entrepreneurial activities of the informal economy. The present study applies this argument to an analysis of women's self‐employment in the U.S. South during the Great Depression. Census data show that in large southern cities in 1940, the unemployment of black women was meaningfully reduced by the self‐employment of these women in domestic service. These data further suggest that dynamics of race, unemployment, and the self‐employment of women in domestic service can be represented by an inverted‐U‐shaped labor absorption curve. These results make several contributions to research on race, labor‐market disadvantage, and self‐employment in the informal sector.     

Detecting Co‐Movements in Non‐Causal Time Series

This paper introduces the notion of common non‐causal features and proposes tools to detect them in multivariate time series models. We argue that the existence of co‐movements might not be detected using the conventional stationary vector autoregressive (VAR) model as the common dynamics are present in the non‐causal (i.e. forward‐looking) component of the series. We show that the presence of a reduced rank structure allows to identify purely causal and non‐causal VAR processes of order P>1 even in the Gaussian likelihood framework. Hence, usual test statistics and canonical correlation analysis can be applied, where either lags or leads are used as instruments to determine whether the common features are present in either the backward‐ or forward‐looking dynamics of the series. The proposed definitions of co‐movements are also valid for the mixed causal—non‐causal VAR, with the exception that a non‐Gaussian maximum likelihood estimator is necessary. This means however that one loses the benefits of the simple tools proposed. An empirical analysis on Brent and West Texas Intermediate oil prices illustrates the findings. No short run co‐movements are found in a conventional causal VAR, but they are detected when considering a purely non‐causal VAR.
