the turning black tide energy prices and the canadian dollar the authors revisit the relationship between energy prices and the canadian dollar in the amano and van norden 1995 equation which shows a negative relationship such that higher real energy prices lead to a depreciation of the canadian dollar

does oil price variability affect asean exchange rates evidence from panel cointegration test abstractusing panel data this article investigates the long run relationship between real oil prices and real exchange rates for selected asean countries by utilizing quarterly data from 1973 q1 to 2013 q4 the modelling implementation starts with the determination of the stationarity condition of the variables which are found to be integrated of order one using maddala and wu s 1999 panel cointegration test the article finds evidence of cointegration among the variables the fully modified ols fmols and dynamic ols dols are then used to estimate the long run relationship between the variables followed by applying toda yamamoto causality test the findings exhibit bidirectional causality between real oil prices and real exchange rates in the long run where it is highly significant

public capital and long run costs in u k manufacturing a model of u k manufacturing production that incorporates the inputs of public as well as private capital is specified and estimated the model is then used to measure the contribution of public capital to productivity growth over the period 1966 to 1990 it is found that before 1980 the public and private capital contributions were of comparable magnitude after 1980 the contribution of public capital declined significantly copyright 1993 by royal economic society

non linear hybrid exchange rate modeling and trading profitability in the foreign exchange market abstract a neuro fuzzy decision making technology is designed and implemented to obtain the optimal daily currency trading rule it is found that a non linear artificial neural network exchange rate microstructure hybrid model combined with a fuzzy logic controller generates a set of trading strategies that earn a higher rate of return compared to the simple buy and hold strategy after accounting for realistic transaction costs the gains from utilizing a dynamic neuro fuzzy model are still present

the mirage of floating exchange rates this note summarizes some of the highlights of my longer paper with guillermo calvo fear of floating many emerging market countries have suffered financial crises one view blames soft pegs for these crises adherents to that view suggest that countries move to corner solutions hard pegs or floating exchange rates we analyze the behavior of exchange rates reserves and interest rates to assess whether there is evidence that country practice is moving toward corner solutions we focus on whether countries that claim they are floating are indeed doing so we find that countries that say they allow their exchange rate to float mostly do not there seems to be an epidemic case of fear of floating

refining for export and the convergence of petroleum product prices abstract the petroleum refining industry has changed over the past decades from one in which capacity primarily served local and regional markets to one in which trade in refined petroleum products has become more widespread we investigate the hypothesis of increasing globalization by examining the convergence of prices for refined products across different markets using data on refined products from market centers in the us and europe we test for convergence of prices using standard time series techniques the data plainly show that markets for refined petroleum products have become more interrelated as europe exported its gasoline surplus and global demand for petroleum products approached refining capacity econometric evidence supports the hypothesis that the us and european markets for oil and refined products are integrated we find evidence that a structural break during the financial crisis of 2008 changed the long run equilibrium price relationships and the short run price dynamics refined product markets are likely to experience continued globalization given trends in the united states and europe and because of key export oriented refining capacity investments made to take advantage of access to specific crude oil sources

adaptive estimation of cointegrated models simulation evidence and an application to the forward exchange market the paper reports simulation and empirical evidence on the finite sample performance of adaptive estimators in cointegrated systems adaptive estimators are asymptotically efficient even when the shape of the likelihood function is unknown we consider two representations of cointegrated systems triangular cointegrating regressions and error correction models the motivation for and advantages of adaptive estimators in such systems are discussed and their construction is described we report results from the estimation of a forward exchange market unbiasedness regression using the adaptive and competing estimators and provide related monte carlo simulation evidence on the performance of the estimators copyright 1999 john wiley sons ltd

the imf a bird s eye view of its role and operations the international monetary fund imf is the world s premier international financial institution with 184 member countries and active programmes in a significant number of them at any one time the fund attracts a great deal of attention much of it critical but the discussion is often polemic in style strongly held but frequently opposing views are expressed this survey attempts to examine in an objective way the theory and evidence relating to the fund s operations many aspects of the empirical research are relatively recent and a universal consensus is yet to emerge as a consequence there is scope for disagreement to persist however the research is also gradually clarifying many important issues the format for the survey is to examine the life cycle of imf arrangements what makes a country turn to the fund for assistance should the imf be lending what influences the outcome of negotiations and the design of programmes are imf programmes effective and why do some countries make prolonged use of imf resources for completeness there is also some discussion of the history of the imf the extent to which fund policies have been influenced by advances in economic theory and the fund s systemic role important organisational and governance issues are also covered briefly although primarily adopting an economist s perspective the survey reflects the growing recognition that in order to understand the imf s operations economics has to be combined with politics examining the imf is an exercise in applied political economy copyright 2007 the author journal compilation 2007 blackwell publishing ltd

tests for parameter instability in regressions with i 1 processes this article derives the large sample distributions of lagrange multiplier lm tests for parameter instability against several alternatives of interest in the context of cointegrated regression models the fully modified estimator of phillips and hansen is extended to cover general models with stochastic and deterministic trends the test statistics considered include the supf test of quandt as well as the lm tests of nyblom and of nabeya and tanaka it is found that the asymptotic distributions depend on the nature of the regressor processes that is if the regressors are stochastic or deterministic trends the distributions are noticeably different from the distributions when the data are weakly dependent it is also found that the lack of cointegration is a special case of the alternative hypothesis considered an unstable intercept so the tests proposed here may also be viewed as a test of the null of cointegration against the alternative of no cointegration the tests are applied to three data se

implications of consumer heterogeneity in time series estimates of us money demand the money demand function has traditionally been estimated with income and interest rates typically employing quite lengthy time series controversy however surrounds the importance of heterogeneous agents in monetary economics and throughout macroeconomics more generally in particular if proportions of agents with different traits and hence different money demands are changing over time ignoring those changes may bias estimated income and interest elasticities this concern as well as that of appropriate functional form is explored here controlling for consumer heterogeneity has surprising effects on the estimated elasticities of traditional variables

oil prices and the rise and fall of the us real exchange rate abstract questions of the relative importance of real vs monetary shocks in explaining exchange rate movements still have no widely accepted answer despite their importance both for the research agenda and for policy questions we examine this issue using a variety of empirical techniques for the us effective exchange rate we find that a stable link exists between oil price shocks and the us real effective exchange rate over the post bretton woods period the results suggest that oil prices may have been the dominant source of persistent real exchange rate shocks and that energy prices may have important implications for future work on exchange rate behavior

estimating shocks and impulse response functions this paper examines the issue of how to identify the shocks in a cointegrated var when the following assumptions are made the variables can be classified as endogenous or exogenous there are as many cointegrating relations as endogenous variables the cointegrating vectors are identified and they contain at least one exogenous variable it is shown that with these assumptions it is possible to identify the shocks without the use of further restrictions on the covariance matrix of the disturbances or the short run dynamics if the long run parameters are known the whole model can be estimated by ols the analysis is extended to allow the var to have both stationary and non stationary variables an illustration of the method is provided using the traditional benchmark var model involving us data on output prices interest rates and money a liquidity effect is not found using this var methodology

co integration error and purchasing power parity between canada and the united states the concept of cointegration and the associated error correction representation of a dynamic process see r f engle and c w g granger 1987 is applied to the purchasing power parity relationship between canada and the united states the results are supportive of purchasing power parity as a long run equilibrium relationship between the canadian dollar american dollar exchange rate the purchasing power parity relationship is maintained although with different dynamic mechanisms during both fixed and flexible exchange rate regimes

the influence of elections on imf programme interruptions using panel data for 104 countries between 1975 and 1998 this article tries to explain interruptions of imf programmes around election dates in the recipient countries on average programmes seem to be more likely to break down before elections this increase in interruption probabilities is however less severe in more democratic countries in true democracies interruption frequencies are even lower prior to elections while no other political variables than elections and democracy were found to influence compliance systematically programme interruptions are significantly more likely in countries with high government consumption high levels of short term debt and low gdp per capita at programme initiation

price discrimination by u s and german exporters the insensitivity of the u s trade balance to the sharp depreciation of the dollar in the past three years has revived interest in the relationship between exchange rates and the trade balance a central issue in most analyses of the relation between the current account and the exchange rate concerns the price adjustment process the simple integrated competitive market model predicts that local currency prices should change in proportion to the nominal exchange rate for a country too small to influence world prices the relationship between local currency import prices and exchange rates has been referred to as the pass through relationship in the empirical literature in international economics if the proportional relationship between import prices and exchange rates holds pass through is said to be complete accounts of recent u s experience cite the failure of dollar prices of imported goods to rise in proportion to exchange rates i e incomplete pass through as an important factor in explaining the persistence of the trade deficit unfortunately observations on pass through alone provide limited insight into the behavior of markets since incomplete pass through is consistent with at least two fundamentally different paradigms one is the standard competitive model of trade in which the law of one price holds but exchange rate fluctuations are associated with large changes in import demand due to other factors for example if dollar appreciation is correlated with increases in world demand and industry marginal cost is increasing then pass through will be less than complete the other is an imperfectly competitive model in which exporters are capable of price discriminating across destination markets a phenomenon paul krugman 1987 has labeled pricing to market in this model incomplete pass through is typically associated with fluctuations in the markup of price over marginal cost on exports 2 these fluctuations in markups are believed to be countryspecific they do not reflect the behavior of prices to other export destinations both models are plausible explanations of recent u s experience unfortunately it is impossible to distinguish between these competing models using only information on import prices and exchange rates for a single country in order to distinguish between the competing models an empirical analysis of goods prices and exchange rates must be capable of measuring either marginal cost or the markup over marginal cost either of these tasks poses formidable empirical problems much of the empirical literature in industrial organization has been concerned with precisely these issues since markups are an important measure of the competitiveness of industries

neopatrimonialism and the political economy of economic performance in africa critical reflections during the past two decades neopatrimonialism has become the convenient all purpose and ubiquitous moniker for african governance the school of thought behind this research program which the author refers to as the neopatrimonialism school has produced an impressive literature on africa its analysis informs policymakers and its language permeates media reportage on african states while neopatrimonialism has long been a focus of development studies in recent times it has assumed politically and economically exigent status the school identifies causal links between neopatrimonialism and economic performance and makes predictions drawing from what is referred to as the logic of neopatrimonialism neopatrimonialism is said to account for trade policies hyperinflation economic stagnation low investment in infrastructure urban bias andultimately the lack of economic development in africa this article examines the empirical basis of predictions and policy prescriptions it argues that while descriptive of the social practices of the states and individuals that occupy different positions within african societies the concept of neopatrimonialism has little analytical content and no predictive value with respect to economic policy and performance

the imf and the mobilisation of foreign aid abstract particularly in the context of the millennium development goals there has been much discussion of the association between the international monetary fund and bilateral aid flows what role should the fund be playing in helping to achieve the mdgs some observers have suggested that the fund should seek to reduce its role in poor countries and should be minimising its own lending they see aid donors taking on a larger role and present the imf and aid donors as substitutes others envisage a much bigger lending role for the fund this may hint at complementarities although this discussion raises important policy issues there are very few studies that examine the relationship empirically this paper attempts to help fill this gap it explores the extent to which the imf has had a catalytic effect on official development assistance and the potential channels through which catalysis might work it finds strong evidence of a positive association and suggests that this may have more to do with condit

commodity currencies and equity flows abstract this paper analyzes the relationship among the prices of natural resources returns on equity and nominal exchange rates of the developed countries where primary commodities are an important share of exports australia canada and new zealand it is found that the portfolio rebalancing motive of hau and rey hau h rey h 2006 exchange rates equity prices and capital flows review of financial studies 19 1 273 317 is weaker for these countries one possible explanation of this finding is that commodity prices due to their flexibility play a special role in the transmission of shocks by linking equity markets across countries and reducing the need for portfolio rebalancing

a new approach to decomposition of economic time series into permanent and transitory components with particular attention to measurement of the business cycle abstract this paper introduces a general procedure for decomposition of non stationary time series into a permanent and transitory component allowing both components to be stochastic the permanent component is shown to be a random walk with drift and the transitory or cyclical component is a stationary process with mean zero the decomposition methodology which depends only on past data and therefore is computable in real time is applied to the problem of measuring and dating business cycles in the portwar u s economy we find that measured expansions and contractions are of roughly equivalent duration and that our dating of cyclical episodes tends to lead the traditional nber dating and to a lesser extent the growth cycle chronology of zarnowitz and boschan 1977

modeling the demand for narrow money in the united kingdom and the united states abstract despite the importance of well specified empirical money demand functions for inference forecasting and policy problems in modeling have arisen concerning the economic theories of money demand the data institutional frameworks financial innovation and econometric implementation by developing constant data coherent m 1 demand equations for the u k and the u s we investigate these issues and explain such puzzles as missing money the great velocity decline and the recent explosion in m 1 the endogeneity of money the lucas critique and the non invertibility of our m 1 models are also discussed

an asymmetric error correction model of uk consumer spending this paper augments the granger and lee journal of applied econometrics 4 1989 non symmetric error equilibrium correction model to assess the possibility that in the aggregate consumers respond differently to different types of disequilibrium error this idea is illustrated using an engle granger implementation of the davidson hendry srba and yeo dhsy economic journal 80 1978 model the disequilibrium error is endogenously determined by the long run empirical model and a binary dummy variable captures two alternative states above and below equilibrium spending interaction of the dummy variable with key variables in a short run dynamic model of uk consumer spending augments the dynamics of the dhsy model income elasticities inflation elasticities and speeds of adjustment are all seen to change significantly depending on whether the disequilibrium error is positive or negative and is suggestive of asymmetric behaviour on the part of consumers moreover the asymmetrically augmented mode

money stock targeting and money supply a closer examination of the data in a recent paper mercenier and sekkat 1988 use a linear quadratic model to examine the willingness of a monetary authority in a small open economy to target its exchange rate based on their empirical results the authors conclude that the bank of canada has displayed a willingness to use the money supply to target the canada us exchange rate we re examine their empirical results using a different estimation approach and with different assumptions about the forcing process of the exogeneous variables we also extend the sample period to include more recent observations while we find some weak evidence to support their conclusion the results in general suggest that a linear quadratic model may not be a particularly useful representation of the assumed exchange rate targeting by a monetary authority

currency fluctuations in the post bretton woods era the international monetary landscape that has emerged since the felling of bretton woods is characterized by a hybrid exchange rate system that lies somewhere between the textbook polar cases of a gold standard and a pure float this system has relatively flexible exchange rates between major countries active central bank intervention in the market for the major currencies and predominantly fixed exchange rates relative to the dollar or to some basket of currencies for less developed countries and newly industrializing nations the majority of research on currency markets since the early 1970s has focused on the characteristics of flexible exchange rates under this hybrid regime my thesis is that this research has been unsuccessful the proportion of monthly or quarterly exchange rate changes that current models can explain is essentially zero even after the fact forecasts that use actual values instead of forecasted values of the explanatory variables cannot explain major currency movements over the post bretton woods era this result is quite surprising since exchange rate changes would be entirely unpredictable only in very special cases of the theoretical models discussed as the discussion below will argue it is not a general implication of market efficiency that exchange rates follow a random walk process 1

have north south growth linkages changed abstract this paper provides econometric evidence suggesting that the traditional tradebased business cycle linkages between the north and the south have changed many countries in the south particularly in asia appear to have become more resilient to cyclical movements in the north and play a more significant role in sustaining global activity a number of factors may have contributed to these changes improved domestic policies and more open trade and exchange regimes closer financial linkages with the north and a substantial increase in capital flows a marked rise in intraregional trade and greater diversification of the exports of the south

was it real the exchange rate interest differential relation over the modern floating rate period in this paper we explore the relationship between real exchange rates and real interest rate differentials in the united states germany japan and the united kingdom contrary to theories based on the joint hypothesis that domestic prices are sticky and monetary disturbances are predominant we find little evidence of a stable relationship between real interest rates and real exchange rates we consider both in sample and out of sample tests one hypothesis that is consistent with our findings is that real disturbances such as productivity shocks may be a major source of exchange rate volatility this paper investigates the empirical relationship between major currency real exchange rates and real interest rates over the modern post march 1973 flexible rate experience the exchange rates examined here include the dollar mark dollar yen and dollar pound rates our two major findings are as follows first the data do not indicate a strong correspondence between real interest rate differentials short term or long term and real exchange rates this finding appears to conflict with the predictions of most monetary and portfolio balance models of exchange rate determination though the conflict can be substantially reconciled if aggregate disturbances are primarily real in nature i e changes in productivity tastes etc it is true that in many cases the sign of the estimated exchange rate interest rate differential relationship is consistent with the possible predominance of financial market disturbances but the relationship is not stable enough to be statistically significant second although one does find some evidence of a unit root in both real exchange rates and long term but not shortterm real interest differentials these two series do not appear to be linearly cointegrated hence the nonstationarity or near nonstationarity in the two series cannot be attributed to the same factor in section i we briefly describe a class of small scale monetary models of exchange rate determination the importance of this class of models for empirical work derives from its strong predictions about how the exchange rate will move

sources of fluctuations in real and nominal exchange rates this paper attempts to distinguish empirically real versus nominal sources of fluctuations in real and nominal exchange rates the distinction is obtained by imposing the following restriction on the bivariate vector autoregression of real and nominal exchange rates over the current flexible rate period nominal shocks are required to have no permanent effect on the level of the real exchange rate given this identification scheme the author analyzes the dynamic effects and relative importance of real and nominal shocks with regards to exchange rates the findings indicate that real shocks dominate nominal shocks for both exchange rate series over short and long frequencies copyright 1992 by mit press

japan s financial deregulation and linkage of the gensaki and euroyen deposit markets summary this paper examines whether japan s financial deregulation weakened the linkage between the euroyen and gensaki markets it defines and analyses the linkage of the two markets in terms of the persistence and predictability of yield spreads as well as cross market causality by using johansen tests and an error correction model this paper shows first cross market causality before and after deregulation and second one common trend in interest rates substantial gensaki euroyen yield spreads and a slower response of the one month gensaki euroyen yield spread to a shock after deregulation

the role of the imf in low income countries the question of whether the imf should effectively engage with its low income member countries has recently generated a wide debate among development economists policymakers and advocates from nongovernmental organizations this note elaborates on the important role that the imf can play in its lowincome member countries points to some current problems with the fund s engagement with these countries and suggests avenues for future improvement

net foreign assets and international adjustment the united states japan and germany abstract this paper examines external adjustment in the usa japan and germany from the perspective of net foreign asset positions it asks two questions what are in the long run the determinants of net foreign asset equilibrium what are in the short run some of the adjustment mechanisms sustaining that equilibrium an analysis of post war data produces two insights first using a cointegration approach the existence of long run net foreign asset equilibrium can be identified it is a function of demographic variables and public debt second deviations from long run equilibrium give rise to feedback through different components of domestic absorption in the three countries

shifting fortunes the political economy of financial liberalization in nigeria abstract on the recommendation of the world bank nigeria began to liberalize its financial sector in 1986 contrary to the prediction of financial repression theory savings and investment decline in the wake of banking deregulation by 1995 the nigerian financial system was in a state of collapse the paper locates the main failure of nigeria s financial deregulation in the political and institutional setting of reform the institutional mechanisms needed to supervise and regulate banking under the new system were absent while private sector banking capacities were weak moreover financial liberalization was quickly captured by a clientalist state as a means of reallocating rents to strategic constituents an additional precipitating factor was macroeconomic instability the paper points to the importance of incorporating political and institutional variables into any model of financial reform or transformation

trade taxes and tribute market liberalizations and the new importers in west africa this paper examines dynamics of state business relations in the era of trade liberalization in senegal and cote d ivoire it challenges the orthodox view that replacing nontariff barriers such as licenses and quotas with tariffs depoliticizes trade reduces commercial rent seeking activities and creates a level playing field which will encourage underground activities to surface allowing the state to capture more revenue the paper illustrates that liberalization failed to suppress commercial rent seeking helped to encourage the ascendancy of new politically connected merchant groups the mourides in senegal and the lebanese in cote d ivoire and to some degree increased tax evasion leading to the further erosion of state revenue flows the cases show that trade centered rentierism is rooted in structural features of these west african economies

commodity currencies and commodity prices modelling static and time varying dependence abstractthis article employs the copula approach to study the relationship between exchange rates and commodity prices for large commodity exporters using data for the nominal exchange rates of four commodity currencies australian canadian and new zealand dollars and norwegian krone against the us dollar and the relevant country specific commodity price indices constructed on a daily basis we find 1 a positive dependence between the values of commodity currencies and commodity indices i e a commodity index increases when a respective currency appreciates and provides several explanations for this finding 2 no major asymmetries in the tail dependence for most pairs of exchange rates and commodity indices and 3 a pronounced increase in the time varying tail dependence following the global financial crisis

empirical models of the exchange rate separating the wheat from the chaff various popular exchange rate models a standard monetary model a portfolio balance model and sticky price models are estimated and evaluated using u s canadian data for the 1970s nonnested hypothesis tests demonstrate that none are correctly specified the data suggest 1 the exchange rate persistence observed is not fully explained by any of the models 2 the small durbin watson statistics indicate longer lags are required 3 the current account is a useful explanatory variable 4 the portfolio balance model fits the data well but has potentially serious problems measuring the stock of foreign assets this abstract was borrowed from another version of this item

measuring market power for some industrial sectors in austria this paper applies an oligopoly model which parameterizes the degree of market power for two industrial sectors glass industry non electrical machinery in austria in contrast all other paper in the new empirical indsutrial organization literature we account for the non stationarity characteristics of the data series a dynamic specification procedure which assumes structural long run equilibrium relationships is therefore applied since a simultaneous system with non linear cross equation restrictions is implied by the economic model a full information maximum likelihood method is used the data reveal a higher degree of market power for the glass industry than for non electrical machinery this hierarchy is in line with the position of these industries for concentration rates and herfindahl indices

terms of trade and real exchange rates the canadian evidence abstract this paper presents empirical evidence linking the canada us real exchange rate with the terms of trade using recently developed econometric methods for nondashstationary data we find that the real exchange rate is cointegrated with terms of trade variables and that causality runs from the terms of trade to the exchange rate we then construct a simple exchange rate equation that satisfies several specification tests and performs better than a random walk in post sample forecasting experiments the results suggest that much of the variation in the real exchange rate is attributable to movements in the terms of trade and that the influence of monetary factors is secondary

regression direction and weak exogeneity abstract the absence of testing for weak exogeneity in money demand has often led to stark conditioning claims regarding the validity of price equations this paper uses the johansen procedure to explore the conditioning properties of money demand systems for nonborrowed reserves m1 and m2 our results show that irrespective of the specification of the cointegrating relation a feedback mechanism enters the equation for money the opposite however is not true for the price equations the results also cast a warning for single equation models of money demand in that weak exogeneity is sensitive to how the system is defined

exchange rate predictability the main goal of this article is to provide an answer to the question does anything forecast exchange rates and if so which variables it is well known that exchange rate fluctuations are very difficult to predict using economic models and that a random walk forecasts exchange rates better than any economic model the meese and rogoff puzzle however the recent literature has identified a series of fundamentals methodologies that claim to have resolved the puzzle this article provides a critical review of the recent literature on exchange rate forecasting and illustrates the new methodologies and fundamentals that have been recently proposed in an up to date thorough empirical analysis overall our analysis of the literature and the data suggests that the answer to the question are exchange rates predictable is it depends on the choice of predictor forecast horizon sample period model and forecast evaluation method predictability is most apparent when one or more of the following hold the predictors are taylor rule or net foreign assets the model is linear and a small number of parameters are estimated the toughest benchmark is the random walk without drift

international negotiations in the shadow of national elections this study examines the role elections play in negotiations between states and the international monetary fund imf although loans made by the imf often require countries to introduce painful austerity measures that provoke a backlash from angry citizens some governments are able to negotiate more favorable terms than others original data on the substantive content of imf loans show that governments leverage imminent elections to obtain more lenient loan terms conditions that require labor market reforms in exchange for imf financing are relatively less stringent in loans negotiated within six months before a pending democratic election all else equal the further away elections are from loan negotiations the more stringent the labor conditions included in countries loan programs elections give governments leverage in their international negotiations and this leverage is effective even when states negotiate with unelected bureaucrats during times of economic crisis

the linear quadratic adjustment cost model and the demand for labour in this paper we demonstrate a new way of testing the linear quadratic adjustment cost lqac model under rational expectations we illustrate how the parameter restrictions arising from this model can be formally specified and we use these restrictions to extent the technique of campbell and shiller 1987 to a wider class of models based on present value relations potentially the demand for labour is an area in which the lqac model can find applicability in practice and subsequently we analyse sectoral labour demand in danish manufacturing we find however that for our data set the quadratic adjustment cost model under rational expectations can be rejected

declining discount rates and the fisher effect inflated past discounted future uncertain and persistent real interest rates underpin one argument for using a declining term structure of social discount rates in the expected net present value enpv framework despite being controversial this approach has influenced both the inter agency working group on cost benefit analysis and the uk government s guidelines on discounting we first clarify the theoretical basis of the enpv approach then rather than following previous work which used a single series of u s treasury bond returns we treat nominal interest rates and inflation as co integrated series and estimate the empirical term structure of discount rates via the fisher effect this nests previous empirical models and is more flexible it also addresses an irregularity in previous work which used data on nominal interest rates until 1950 and real interest rates thereafter as we show the real and nominal data have very different time series properties this paper therefore provides a robustness check on previous discounting advice and updated methodological guidance at a time when governments around the world are reviewing their guidelines on social discounting the policy implications are discussed in the context of the social cost of carbon nuclear decommissioning and public health

commodity currencies and the real exchange rate abstract this paper examines whether the real exchange rates of commodity exporting countries and the real prices of their commodity exports move together over time using international monetary fund imf data on the world prices of 44 commodities and national commodity export shares we construct new monthly indices of national commodity export prices for 58 commodity exporting countries over 1980 2002 evidence of a long run relationship between national real exchange rate and real commodity prices is found for about one third of the commodity exporting countries the long run real exchange rate of these commodity currencies is not constant as would be implied by purchasing power parity based models but is time varying being dependent on movements in the real price of commodity exports

empirical evidence on the strength of the monetary transmission mechanism in canada an aggregate approach abstract this paper examines the transmission of monetary policy in canada it emphasizes the transmission through interest rates and the exchange rate rather than through changes in monetary aggregates and provides empirical evidence on the strength of these channels using a highly aggregated structural model implications of these structural equations for the dynamic effects of monetary policy are explored through a simulation analysis

food marketing liberalization and trader entry evidence from madagascar abstract food marketing liberalization was expected to induce massive trader entry and competitive markets in africa despite evidence of trader entry enterprise expansion remains difficult and many claim market power persists though perhaps in different hands this paper confronts this puzzle of substantial market entry that might not foster competition data from madagascar reveal distinct groups within rural food marketing channels separated by intraindustry mobility barriers that limit entry to a few niches moreover individuals place within the rural marketing network is defined largely by a priori social identity so the experience of food marketing liberalization varies across socially distinct subpopulations

international negotiations and domestic politics the case of imf labor market conditionality what is the role of international organizations ios in the formulation of domestic policy and how much influence do citizens have in countries negotia tions with ios we examine these questions through a study of labor related condi tionality in international monetary fund imf loans using new data from imf loan documents for programs from 1980 to 2000 we test to see if citizens economic interests influence imf conditionality we examine the substance of loan conditions and identify those that require liberalization in the country s domestic labor market or that have direct effects on employment wages and social benefits we find evi dence that democratic countries with stronger domestic labor receive less intrusive labor related conditions in their imf loan programs we argue that governments con cerned about workers opposition to labor related loan conditions negotiate with the imf to minimize labor conditionality we find that the imf is responsive to domes tic politics and citizens interests

oil price drivers geopolitical uncertainty and oil exporters currencies abstract empirical relationships between crude oil prices and exchange rates of oil exporting countries tend to vary over time i use econometric models of the norwegian and canadian nominal exchange rates to investigate whether such time variation could reflect shifts in the key drivers of oil prices over time results suggest that demand and supply driven oil price increases strengthen these currencies to different extents in contrast heightened geopolitical uncertainty and associated oil price increases go together with a weakening of oil exporters currencies the latter result may explain coincidences of higher oil prices and a weakening of oil exporters currencies

oil price shocks and their transmission mechanism in an oil exporting economy a var analysis informed by a dsge model abstract this paper examines the macroeconomic effects of oil price shocks and the oil shock transmission mechanism in an oil exporting country canada we use a structural var with sign restrictions that comes from a two country dynamic stochastic general equilibrium dsge model to jointly identify oil price domestic supply and u s and domestic monetary policy shocks this identification strategy not only controls for reverse causality from the canadian and u s macroeconomic conditions to the real oil prices but more importantly it also allows for contemporaneous interactions between the canadian and u s variables we find that oil shocks have a stimulative effect on canadian aggregate demand appreciate the canadian dollar improve the terms of trade and reduce real wages foreign disturbances including innovations in oil prices and the u s interest rate have a significant influence on canadian economic activities our counterfactual analysis indicates that the reaction of the u s interest rate as an indirect transmission channel for oil price shocks plays a moderate role in explaining the real exchange rate and inflation but has negligible impacts on the canadian output and interest rate

the exchange rate and purchasing power parity extending the theory and tests abstract this paper analyzes the exchange rate in a no arbitrage or real business cycle equilibrium model and provides empirical evidence for this model vis a vis ppp our contribution is to show based on a generalization of the equilibrium model of exchange rates that i the test equation linking the exchange rate to fundamentals should allow for international heterogeneity in time preferences and risk attitudes as well as noise that is the model should not be tested as an exact relation ii empirical work should use levels of variables rather than first differences and iii tests on the existence of long run relations should be complemented by test on the signs of the coefficients our empirical work shows that as a long run relation the generalized model outperforms ppp moreover under the generalized model quarterly deviations from the estimated long term relation have a half life of only four to five quarters

cointegration analysis with structural breaks and deterministic trends an application to the canadian dollar this article applies recent developments in cointegration analysis with structural breaks and deterministic trends to analyse the relationship between the real canada us exchange rate and commodity prices previous empirical studies disagree on whether these variables are cointegrated the root of disagreement could be in the handling of deterministic trends and potential structural breaks i find that even after controlling for these matters the question of whether the real exchange rate and commodity prices are cointegrated for canada remains unresolved

how does the border affect productivity evidence from american and canadian manufacturing industries abstract this study reports on how much productivity fluctuations are industry specific versus country specific for the manufacturing industries in canada and the united states the correlation between cross border pairings of the same industry are found to be more often highly correlated than previously thought furthermore the study confirms earlier findings that the similarity of input use can help describe the comovement of productivity fluctuations across industries

economic reform and political transition in africa the quest for a politics of development the 1980s were bracketed by crises in africa as protracted economic malaise was succeeded by a wave of political reform analysts have sought to understand the sources of economic decline as well as the political requisites for recovery in the region neoclassical and structuralist analyses have been challenged by state centric views of economic change the latter perspective emphasizes the need for capable developmental states as a basis for long term adjustment but a political theory of economic change is still lacking such a theory must address the institutional foundations of growth as well as the shifting basis of social coalitions in african regimes political liberalization suggests the possibility of a new setting for economic reform though the effects of political reform on institutions and coalitions remain ambiguous and democratization cannot be regarded as a panacea for the region s developmental failure future research must look more closely at the interests and structures in transitional regimes and scholars should adopt a more comparative vantage on africa s challenges of reform

lost in transition the costs and consequences of sectoral labour adjustment this paper uses an equilibrium search and matching model to study canada s sectoral labour adjustment in 2002 2006 during an increase in global commodity prices and exchange rate appreciation i estimate economically significant adjustment costs for the aggregate economy in this episode and demonstrate that difficulty in transferring skills between jobs for individual workers can be an important contributor to these aggregate costs the analysis also demonstrates that the level of unemployment benefits impacts the economy s sectoral composition its aggregate productivity and the speed of its adjustment to shocks ce texte utilise un modele d equilibre de la recherche et de l arrimage pour etudier les ajustements sectoriels du travail au canada dans la periode 2002 2006 une periode d appreciation des prix globaux des produits de base et du taux de change j estime que les couts d ajustement sont economiquement significatifs pour l economie agregee au cours de cet episode et que la difficultea transferer les competences entre emplois pour les travailleurs individuels peut etre une source importante de ces couts agreges les analyses montrent aussi que le niveau des prestations d assurance emploi a un impact sur la composition sectorielle de l economie sur la productivite et sur la vitesse des ajustements aux chocs

market power inflation targeting and commodity currencies abstract the commodity currency literature highlights the robust exchange rate response to fluctuations in global commodity prices that occurs for major commodity exporters the magnitude of the response however varies widely across countries and over time horizons this paper examines the real exchange rates of 51 commodity exporters over the period from 1980 to 2010 and finds that in the long run a higher degree of market power in the world commodity trade can reduce the exchange rate response while in the short run an inflation targeting regime can amplify it these differential impacts across countries and horizons are of particular relevance for monetary policy making and for trade strategy in commodity abundant economies

market reform as a stimulus to particularistic politics we know little about how market reform affects political development especially citizens behavior market reform advocates prescribe that citizens should reduce their reliance on the state turn to nonstate actors for assistance and obtain limited state goods and services through their membership in certain social categories not their particular traits an analysis of three mass surveys and 232 interviews the author conducted in central asia along with additional data from 24 postcommunist countries reveals that market reform can have effects opposite from those prescribed individuals may make particularistic demands of government officials instead of relying on nonstate actors this occurs in countries where state economic intervention was substantial and where reforms reduced the state s economic role but failed to develop market enhancing institutions under these conditions individuals informally seek resources from state officials because nonstate actors do not offer substitute resources and

ricardian equivalence and the public and private saving nexus in india abstractthis study tests the ricardian equivalence theorem ret and examines the responsiveness of private saving to public saving in india most estimators do not provide support for the empirical validity of ret and long run cointegration between public and private saving the increases in household saving hhs seem to have been engendered by the provision of saving incentives institution of saving schemes self driven motivation to save and the precautionary accumulations induced by uncovered uncertainties in incomes rather than by ricardian behaviour of households the self imposed aversion to debt and debt bequest borrowing and liquidity constraints and the intertemporal smoothing of consumption have been the added catalysts that contributed to the increases in hhs the households with binding borrowing constraints inadequate or no insurance and uncovered uncertainties in incomes seem to have been saving more to pay for higher inflation tax the fiscal consolidation and generation of public s

does euro or dollar pegging impact the real exchange rate the case of oil and commodity currencies the aim of this paper is to investigate the equilibrium exchange rates for commodity and oil currencies as well as the discrepancies of their observed exchange rates to these equilibriums to this end first we estimate a long term relationship between the real effective exchange rate and economic fundamentals including the commodity terms of trade the estimation relies on panel cointegration techniques and covers annual data from 1980 to 2007 our results show that real exchange rates co move with commodity prices in the long run and respond to oil price somewhat less than to commodity prices second we assess the degree of misalignment of these currencies as the gap between their observed exchange rate and the estimated equilibrium exchange rate we show that these misalignments are not significantly related to the exchange rate regimes adopted by the countries either pegged or floating however for pegged currencies the size of misalignments significantly depends on the anchor currency either the euro or the dollar a comparison of misalignments of pegged commodity and oil currencies across different periods confirms these results during periods of dollar euro overvaluation currencies pegged to the dollar euro tend to be overvalued the reverse being true when the dollar euro is undervalued consequently pegged currencies are often driven away from their equilibria by wild fluctuations in the key currencies on which they are anchored

the international monetary fund in a time of crisis a review of stanley fischer s imf essays from a time of crisis the international financial system stabilization and development stanley fischer was deputy managing director of the imf from 1994 to 2001 and perhaps more than any other individual he personifies the international rapid response to financial crises in the 1990s this book is a collection of essays written during his tenure at the imf taken together the essays represent the strongest and most logical defense of imf initiatives in the 1990s in print my review essay comprises six parts in parts 2 through 4 i provide an overview of fischer s arguments in three central areas of contention stabilization policy the impact of imf programs on poverty and the imf s anticipation of and response to international financial crisis i then compare fischer s arguments to those raised by the imf s critics during that period the controversial issues of these parts can be resolved only through empirical investigation but on the issues of greatest importance from the financial crises of the 1990s both fischer and the imf s critics make logically consistent arguments with little empirical support in part 5 i review the recent empirical literature to illuminate what evidence has been found in support of or counter to the assertions of fischer and the imf s critics part 6 provides conclusions and suggestions for follow on empirical research

long term trend and short run dynamics of the canadian dollar an error correction modelling approach using quarterly data for 1972 2000 the paper examines the long term and short term movements of the us canadian exchange rate it is found that the standard purchasing power parity condition fails to explain movements of the canadian dollar the explanatory power of the model increases significantly when resource commodity prices are added to the equation short term movements in the canadian dollar are influenced by the interest rate differential between canada and the usa

the politics of adjustment lessons from the imf s extended fund facility the international debt crisis has forced painful economic adjustments on the developing world in the short run it has forced governments to seek to correct payments imbalances through stabilization programs usually undertaken with conditional assistance from the international monetary fund imf the crisis has also revealed deeper weaknesses in many third world economies weaknesses demanding more basic reforms in the structure of incentives prices and investment

globalizing electoral politics political competence and distributional bargaining in the european union this article analyzes electoral cycles in distributional bargaining in the european union the author argues that governments attempt to increase their eu membership benefits above average levels in the preelection period hoping to appear politically competent to voters the theory discusses when and how eu members can increase these gains before elections through negotiations in the council of ministers a time series cross sectional analysis of eu member states annual budget negotiations from 1977 to 2006 supports the existence of conditional electoral cycles in distributional bargaining and generally points to the importance of accounting for such cycles when analyzing patterns of international cooperation

services sector and economic growth in india this study examines the long run equilibrium and short run dynamic relationship between services sector and gross domestic product gdp and between services and nonservices sectors in india the model is estimated using the optimal single equation and the maximum likelihood system estimators all the estimators consistently suggest the cointegrating relationship between services sector and gdp as well as between services and nonservices sectors the estimates of long run elasticity parameters are statistically significant and dimensionally consistent across the estimators the conventional cumulative sum cusum and the new cusum and moving sum mosum tests suggest the stability of the equilibrium residuals and reinforce the cointegrating relationship between the model series the error correction model provides some support for unidirectional granger causality from services sector to gdp the impulse response and variance decomposition analyses instead suggest the bidirectional causality between servic

estimating long run economic equilibria with stochastic trends an asymptotic theory is provided to analyze a menu of currently existing estimators of cointegrated systems we study in detail the single equation ecm seecm approach of hendry our theoretical results lead to prescriptions for empirical work such as specifying seecm s nonlinearly and including lagged equilibrium relationships rather than lagged differences of the dependent variable as covariates simulations support these prescriptions and point to problems of overfitting not encountered in the semiparametric approach of phillips and hansen 1990

food market reform the changing role of the state abstract the liberalization and privatization of food markets has been an important feature of economic reform programmes in many developing countries and donor conditionality has been applied to this end however the agenda needs to move beyond this to the establishment of efficient and equitable marketing systems a major constraint on this has been the weak base of theoretical and empirical knowledge about the characteristics of food markets on which reform programmes have been built three principal areas are identified where further research policy experimentation and sharing of experience are required the role of the state in relation to collective action by market participants the problem of food price instability and the delivery of support to the small scale private sector that has taken over many marketing functions
