state dependent exchange rate pass through behavior abstract we estimate a bayesian threshold vector autoregression tvar to study the relationship between exchange rate pass through and economic activity in canada and mexico both the model comparison and the analysis of impulse response functions provide strong evidence of a nonlinear relationship and suggest that the exchange rate pass through is dependent on the state of the economy in particular the pass through coefficient is higher when the growth rate of output is large and this difference is statistically significant across regimes for both countries furthermore the results show that the degree of pass through is complete in the case of import prices and that it falls along the distribution chain of goods

carbon allowance allocation in the transportation industry abstract this study proposes models for projecting reductions in co 2 emissions of 10 20 30 and 40 compared to business as usual bau using a carbon allowance allocation policy and both unimodal and intermodal modes of transportation the results show that for 10 to 80 decreases in free carbon allowance the intermodal ratio increased from 1 01 to 53 44 which led to decreases in carbon emissions and demand ranging from 10 41 to 48 19 and 8 45 to 7 57 respectively when free carbon allowances are decreased the demand for intermodal systems increases accordingly these results suggest that a carbon allowance allocation policy could mitigate transportation carbon emissions with a relatively small negative impact on economic activity

nominal income targeting in an open economy optimizing model abstract this paper presents simulation results regarding the performance of nominal income targeting a monetary policy rule that sets interest rates in response to deviations of nominal gdp growth from a target path the macroeconomic model is one in which agents solve dynamic optimization problems with rational expectations but in an environment with slow price adjustments in the present version consumption choices reflect habit formation and the economy is open to international flows of goods and securities when calibrated to quarterly us data the model s results suggest that nominal income targeting performs well in relation to inflation targeting and taylor rules

household s preferences and monetary policy inertia abstract interest rates set by central banks puzzlingly move with a certain inertia we show that household s preferences can be important determinants of the optimal interest rate inertia due to their impact on the efficiency of the monetary policy transmission mechanism

experimental comparison of impact of auction format on carbon allowance market abstract carbon allowances auctions are a good way to achieve the carbon allowance allocations under international agreements to address global climate change based on an economic experiment this paper compares three possible carbon allowance auction formats uniform price auction discriminatory price auction and english clock auction with heterogeneous bidders coal power plants and gas power plants from four perspectives carbon price auction efficiency demand withholding and fluctuations in power supplies possibilities of collusion among bidders and impacts of allowance banking and penalty price on bidders behaviors under different auction formats are also examined the results show that 1 when there are relatively more bidders and there are no obvious communications between them despite there being some tacit collusion efficiency of english clock auction is greater than the other two formats 2 when there are relatively fewer bidders and there are obvious communications between them explicit collusions are observed under english clock auction in this case discriminatory price auction helps prevent collusion to some extents 3 in the banking scenario more speculations are observed while penalty price exacerbates price volatility

optimal monetary policy responses to relative price changes abstract an optimizing model with a flexible price sector and a sticky price sector is presented to analyze the effects of relative price changes on inflation fluctuations the relative price of the flexible price good represents a shift parameter of the new keynesian phillips curve the optimal monetary policy is to target sticky price inflation rather than a broad inflation measure although stabilizing the relative price around its efficient value is one of the appropriate goals of the central bank stabilizing sticky price inflation is sufficient for achieving this goal an optimal monetary policy for a small open economy is also discussed

price level convergence and regional phillips curves in the us and emu abstract we use panel estimates of regional phillips curves of the hybrid new keynesian type to study price level convergence within the us and emu regional inflation rates tend to eliminate ppp deviations in both monetary unions with average half lives around 3 years the start of emu did not greatly affect ppp reversion in the euro area where changes in nominal exchange rates accounted for the bulk of the adjustment process before 1999 this role was largely taken over by regional inflation differences since notwithstanding clear evidence of forward lookingness in the us inflation persistence is substantial in both monetary unions

why money talks and wealth whispers monetary uncertainty and mystique this paper analyzes the effect of monetary uncertainty on the inflationary bias and the variance of output and inflation monetary policy uncertainty is modeled as a shock to the central banker s preference for inflation stabilization relative to output stabilization that cannot be observed by the public we find that the mean and variance of inflation increase with the variance of this preference shock however unlike other studies we find that monetary uncertainty may very well have a positive effect on output stabilization and therefore also on society s welfare

optimal monetary policy in a currency area abstract this paper investigates how monetary policy should be conducted in a two region general equilibrium model with monopolistic competition and price stickiness this framework delivers a simple welfare criterion based on the utility of the consumers that can be used to evaluate monetary policy in a currency area if the two regions share the same degree of nominal rigidity the terms of trade are completely insulated from monetary policy and the optimal outcome is obtained by targeting a weighted average of the regional inflation rates these weights coincide with the economic sizes of the region if the degrees of rigidity are different the optimal plan implies a high degree of inertia in the inflation rate but an inflation targeting policy in which higher weight is given to the inflation in the region with higher degree of nominal rigidity is nearly optimal

uncertainty and monetary policy in a wage bargaining model in a wage bargaining model increased uncertainty concerning monetary and real aggregates is shown to give rise to a higher equilibrium unemployment rate moreover the equilibrium unemployment rate is found to depend on the choice of monetary policy regime as this choice affects the uncertainty wage setters face when setting the nominal wage rate it is also shown that the equilibrium inflation rate may depend on uncertainty in such a way that increased uncertainty gives rise to a higher equilibrium unemployment rate as well as a higher equilibrium inflation rate or what has been called stagflation

the impact of china s carbon allowance allocation rules on the product prices and emission reduction behaviors of ets covered enterprises abstract it is an important task for china to allocate carbon emission allowance to realize its carbon reduction target and establish carbon trading market china has designed several allocation rules within seven pilot regions what influence those rules may cause is closely related with the enthusiasm of emission trading scheme ets covered enterprises participation in carbon market and more importantly with the mechanism design and sustainable development of carbon market for this purpose the multi stage profit model is developed to analyze the ets covered enterprises product prices and emission reduction behaviors under different allocation rules the results show that first under the rules of grandfathering self declaration and auctioning when deciding the optimal product price and optimal carbon emission reduction those enterprises may focus on maximizing current stage profit however under the rule of benchmarking those enterprises may care more about the impact of current decisions on the profit in next stage second the optimal product price policy is positively correlated with the price of the same kind products consumers low carbon awareness and government subsidy finally along with the increase of carbon price consumers low carbon awareness and government subsidy and the decrease of carbon emission cap those enterprises tend to reduce carbon emissions

when and how much to talk credibility and flexibility in monetary policy with private information abstract this paper analyzes the role of noisy or imprecise announcements in mitigating the basic credibility problem in monetary policy based on a model where the monetary authority s private information gives rise to an unavoidable trade off between flexibility and credibility the analysis finds that noisy announcements can serve as a meaningful form of communication to make that trade off more favorable however such talk is not cheap the analysis predicts that those central banks who can speak more precisely are those who are less likely to speak at all

do central banks react to the stock market the case of the bundesbank abstract in this paper we ask whether the bundesbank prior to the european central bank taking responsibility for monetary policy in 1999 reacted systematically to stock price movements in contrast to the results for the us our empirical findings show a generally weak relationship between german stock returns and short term interest rates at the daily and the monthly frequency the results are extremely robust to alternative model specifications the evidence is inconsistent with the hypothesis of a systematic reaction of the bundesbank to german stock prices however we do find that as in the us the bundesbank may have reacted to the stock market crash of 1987 by loosening monetary policy

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

a theory of ambiguity credibility and inflation under discretion and asymmetric information this paper develops a positive theory of credibility ambiguity and inflation under discretion and asymmetric information the monetary policymaker maximizes his own politically motivated objective function that is positively related to economic stimulation through monetary surprises and negatively related to monetary growth the relative importance he assigns to each target shifts stochastically through time his current preference trade off is known to him but not to the public when choosing the state contingent path of money growth for the present and the future the policymaker compares the benefits from current stimulation with the costs associated with higher future inflation expectations current monetary growth conveys information to the public about future money growth because there is persistence in the policymaker s objectives although expectations are rational information is imperfect because monetary control procedures are imprecise as a result the public cannot correctly distinguish persistent changes of emphasis on different policy objectives from transitory monetary control errors the public becomes aware of changes gradually by observing past monetary growth credibility is defined in terms of the speed with which the public recognizes changes in the objectives of the policymaker credibility is lower the noisier monetary control and the more stable the objectives of the policymaker looser monetary control and a higher degree of time preference on the part of the policymaker induce him to produce higher and more variable monetary growth when the policymaker is free to determine the accuracy of monetary control he does not always choose the most effective control available in spite of the fact that monetary surprises always have an expected value of zero the reason is that ambiguous control procedures enable the policymaker to generate positive surprises when he cares more than on average about economic stimulation he leaves the inevitable negative surprises for periods in which he cares more about inflation prevention this result provides an explanation for the fed s preference for ambiguity recently documented by goodfriend 1986 the policymaker is more likely to pick more ambiguous control procedures the more uncertain his objectives and the higher his time preference the paper also provides a theoretical underpinning for the well documented crosscountry positive correlation between the level and the variability of inflation

openness imperfect exchange rate pass through and monetary policy abstract this paper analyses the implications of imperfect exchange rate pass through for optimal monetary policy in a linearised open economy dynamic general equilibrium model calibrated to euro area data imperfect exchange rate pass through is modelled by assuming sticky import price behaviour the degree of domestic and import price stickiness is estimated by reproducing the empirical identified impulse response of a monetary policy and exchange rate shock conditional on the response of output net trade and the exchange rate it is shown that a central bank that wants to minimise the resource costs of staggered price setting will aim at minimising a weighted average of domestic and import price inflation

the bundesbank s path to independence evidence from the 1950s the german bundesbank is frequently called the world s most independent and conservative central bank taking account of the path dependency of this reputation both quantitative data and qualitative data on german central bank law and political conflicts are used to determine the factors that contributed to this reputation in the 1950s it is shown that quantitative analysis has its limits and that law might be a misleading indicator in this respect it is rather the analysis of policy conflicts between the bundesbank and the government that yields information on the bank s path to independence

optimal monetary policy in open versus closed economies an integrated approach in clarida et al 1999 hereafter cgg we presented a normative analysis of monetary policy within a simple optimization based closedeconomy framework we derived the optimal policy rule and among other things characterized the gains from commitment also we made precise the implications for the kind of instrument feedback rule that a central bank should follow in practice in this paper we show how our analysis extends to the case of a small open economy openness complicates the problem of monetary management to the extent the central bank must take into account the impact of the exchange rate on real activity and inflation how to factor the exchange rate into the overall design of monetary policy accordingly becomes a central consideration here we show that under certain conditions the monetary policy design problem for the small open economy is isomorphic to the problem of the closed economy that we considered earlier hence all our qualitative results for the closed economy carry over to this case openness does affect the parameters of the model suggesting quantitative implications though the general form of the optimal interest rate feedback rule remains the same as in the closedeconomy case for example how aggressively a central bank should adjust the interest rate in response to inflationary pressures depends on the degree of openness in addition openness gives rise to an important distinction between domestic inflation and consumer price inflation as defined by the cpi to the extent that there is perfect exchange rate pass through we find that the central bank should target domestic inflation and allow the exchange rate to float despite the impact of the resulting exchangerate variability on the cpi kosuki aoki 1999 gali and tommaso monacelli 2000

low inflation pass through and the pricing power of firms abstract recently there has been a significant decline in the degree to which firms pass through changes in costs to prices a decline that is frequently characterized as a reduction in the pricing power of firms the decline appears to be associated with the decline in inflation in many countries the decline has important implications for monetary policy because it affects both forecasts of inflation and the effects of changes in monetary policy on inflation some have argued that the decline in pricing power helped to keep inflation low in the face of apparently strong demand pressures in the united states in the late 1990s this paper puts forth the view that the decline in pass through or pricing power is due to the low inflation environment that has recently been achieved in many countries first a microeconomic model of price setting is used to show that lower pass through is caused by lower perceived persistence of cost changes evidence is then presented showing that inflation is positively correlated with persistence of inflation suggesting that the low inflation itself has caused the low pass through an economy wide model consistent with the micromodel is then presented to illustrate how such changes in pricing power affect output and inflation dynamics in favorable ways but can disappear quickly if monetary policy and expectations change

new directions for stochastic open economy models the paper develops a simple stochastic new open economy macroeconomic model based on sticky nominal wages explicit solution of the wage setting problem under uncertainty allows one to analyze the effects of the monetary regime on welfare expected output and the expected terms of trade despite the potential interplay between imperfections due to sticky wages and monopoly the optimal monetary policy rule has a closed form solution to motivate our model we show that observed correlations between terms of trade and exchange rates are more consistent with our traditional assumptions about nominal rigidities than with a popular alternative based on local currency pricing 2000 elsevier science b v all rights reserved

inflation targeting as a monetary policy rule the purpose of the paper is to survey and discuss in ation targeting in the context of monetary policy rules the paper provides a general conceptual discussion of monetary policy rules attempts to clarify the essential characteristics of in ation targeting compares in ation targeting to other monetary policy rules and draws some conclusions for the monetary policy of the european system of central banks jel classi cation e42 e52

time substitution with application to data envelopment analysis abstract in this paper we analyze resource allocation distinguishing between the decision of when to begin allocation and over how many periods to apply the resources we present analytical results for specific production technologies under different returns to scale assumptions under capacity constraints and for production with technical change using a dynamic activity analysis framework we show how to compute in general optimal solutions for resource intensity use

habit formation in consumption and its implications for monetary policy models this paper explores a monetary policy model with habit formation for consumers in which consumers utility depends in part on current consumption relative to past consumption the empirical tests developed in the paper show that one can reject the hypothesis of no habit formation with tremendous condence largely because the habit formation model captures the gradual hump shaped response of real spending to various shocks the paper then embeds the habit consumption specication in a monetary policy model and nds that the responses of both spending and inflation to monetary policy actions are signicantly improved by this modication jel d12 e52 e43

exchange rate pass through openness and the sacrifice ratio abstract considerable recent work has reached mixed conclusions about whether and how globalization affects the inflation output trade off and suggests that the ultimate effect of openness on the output inflation relationship is influenced by a variety of factors in this paper we consider the impact of exchange rate pass through and examine how pass through conditions the effect of openness on the sacrifice ratio we develop a simple theoretical model showing how the extent of both pass through and openness can interact to influence the output inflation relationship next we empirically explore the nature of these two variables and their interaction results indicate that greater pass through increases the sacrifice ratio that there is statistically significant interaction between pass through and openness and once the extent of pass through is taken into account alongside other factors that affect the sacrifice ratio such as central bank independence openness fails to exert an empirically robust effect on the sacrifice ratio

solution and estimation of re macromodels with optimal policy macro models of monetary policy typically involve forward looking behavior except in rare circumstances we have to apply some numerical method to find the optimal policy and the rational expectations equilibrium this paper summarizes a few useful methods and shows how they can be combined with a kalman filter to estimate the deep model parameters with maximum likelihood simulations of a macro model with staggered price setting interest rate elastic output and optimal monetary policy illustrate the properties of this estimation approach

inflation forecast targeting implementing and monitoring inflation targets abstract inflation targeting is shown to imply inflation forecast targeting the central bank s inflation forecast becomes an explicit intermediate target inflation forecast targeting simplifies both implementation and monitoring of monetary policy the weight on output stabilization determines how quickly the inflation forecast is adjusted towards the inflation target money growth or exchange rate targeting is generally inferior than inflation targeting and leads to higher inflation variability commitment to target rules may be better than commitment to instrument rules

exchange rate pass through to domestic prices does the inflationary environment matter abstract the paper tests a hypothesis suggested by j taylor 2000 low inflation pass through and the pricing power of firms european economic review 44 7 1389 1408 that a low inflationary environment leads to a low exchange rate pass through to domestic prices to test this hypothesis the paper derives a pass through relation based on new open economy macroeconomic models a large database that includes 1979 2000 data for 71 countries is used to estimate this relation there is strong evidence of a positive and significant association between the pass through and the average inflation rate across countries and periods the inflation rate moreover dominates other macroeconomic variables in explaining cross regime differences in the pass through

design of sustainable supply chains under the emission trading scheme increase in environmental concerns together with legislations are forcing industries to take a fresh look at the impact of their supply chain operations on the environment this paper introduces a mixed integer linear programming based framework for sustainable supply chain design that considers life cycle assessment lca principles in addition to the traditional material balance constraints at each node in the supply chain indeed the framework distinguishes between solid and liquid wastes as well as gaseous emissions due to various production processes and transportation systems the framework is used to evaluate the tradeoffs between economic and environmental objectives under various cost and operating strategies in the aluminum industry the results suggest that current legislation and emission trading schemes ets must be strengthened and harmonized at the global level in order to drive a meaningful environmental strategy moreover the model demonstrates that efficient carbon management strategies will help decision makers to achieve sustainability objectives in a cost effective manner

integrated weighting approach to carbon emission quotas an application case of beijing tianjin hebei region abstract the coordinated development of beijing tianjin hebei region has been included in the chinese 12th five year plan as a national strategy accordingly the cooperation of energy saving and environmental protection is an important part at the present stage establishing carbon emission trading market in china is regarded as an effective measure to reduce and control carbon dioxide emission meanwhile it is an important task for government to allocate carbon emission quotas among regions in order to explore the cross provincial carbon trading market mode of china this paper aims to construct a comprehensive index and use the integrated weighting approach to simulate the carbon quota allocation of beijing tianjin hebei region the results show that firstly the indicator of responsibility which is about 0 56 is given relatively more weight among the three indicators by comparison the weights of capacity and potential are 0 13 and 0 30 secondly the provinces with strong economic ability and lower carbon reduction potential may get fewer proportions of carbon emission quotas such as beijing thirdly since undertaking the function transfer and dispersal of beijing and tianjin hebei should have a relatively high carbon emission quotas in the future carbon trading market these results may provide insightful support for decision makers to promote collaborative carbon reduction and allocate carbon quotas in beijing tianjin hebei region of china

nominal rigidity and monetary uncertainty abstract a stochastic macromodel with dynamically optimising wage setting households is used to examine the effect on current macroeconomic variables of an anticipated increase in variability of the money stock there is a nominal rigidity in the form of a money wage set one period in advance in whose absence monetary uncertainty has no effect on current variables we show that for plausible parameterisations monetary uncertainty combined with nominal rigidity raises the nominal interest rate depressing aggregate demand and hence current price and output it also causes the wage to be set higher increasing the natural rate of unemployment

carbon emissions quotas in the chinese road transport sector a carbon trading perspective abstract in response to the growing need to reduce carbon emissions it is necessary to explore the design of carbon trading mechanisms and discuss allocation options for the transport sector this paper examines the allocation of carbon quotas with the introduction of an emissions trading scheme ets in the chinese road transport sector aiming to simulate the allocation of carbon emissions quotas we forecast vehicle possession using a gray forecast model and trend extrapolation consider the carbon dioxide co2 emissions of the transport sector using a top down approach and design three policy scenarios we provide the following findings first vehicle possession in the road transport sector and carbon emissions both display an increasing trend reaching 180 million units and 6 6 billion tons by 2020 respectively second the road transport sector has the largest carbon quota under the benchmark scenario and the smallest under a low carbon scenario the difference between these two scenarios is 2 7 billion tons of carbon emissions finally we design a carbon emissions trading mechanism for the transport sector based on china s special development period and provide a sensitivity analysis

inflation targeting and exchange rate pass through this paper analyzes how endogenous imperfect exchange rate pass through affects inflation targeting optimal monetary policies in a new keynesian small open economy the paper shows that an inverse relation exists between the pass through and the insulation of the economy from foreign and monetary policy shocks and that imperfect pass through tends to decrease the variability of the terms of trade furthermore with cpi inflation targeting in the short run delayed pass through constrains monetary policy more than incomplete pass through and interest rate smoothing amplifies this effect when the pass through decreases the variability in economic activity tends to rise and the trade off between the stabilization of cpi inflation and output worsens in direct relation to how strictly the central bank is targeting cpi inflation in contrast with domestic inflation targeting optimal monetary policy is not constrained and opposite results occur consequently imperfect pass through favors the choice of domestic to cpi inflation targeting

business cycles for g7 and european countries this article proposes classical business cycle turning points for the g7 and a number of european countries based on industrial production this enables the authors to examine the international nature of cyclical movements free from arbitrary assumptions about the trend in particular they show that cyclical assymetry is common with slopes during declines being generally larger in magnitude than during expansions a binary measure of association for expansion and contradiction regimes indicates a core group of european countries related to each other and apparently linked to the united states and japan through germany copyright 1997 by university of chicago press

welfare and macroeconomic interdependence we develop a baseline model of monetary and fiscal transmission in interdependent economies the welfare effects of expansionary policies are related to monopolistic supply in production and monopoly power of a country in trade an unanticipated exchange rate depreciation can be beggar thyself rather than beggar thy neighbor as gains in domestic output are offset by deteriorating terms of trade smaller and more open economies are more prone to suffer from inflationary shocks larger economies benefit from moderate demand led expansions but may be worse off if policy makers attempt to close the output gap fiscal shocks are generally beggar thy neighbor in the long run in the short run they raise domestic demand at given terms of trade thus reducing the welfare benefits from monetary expansions analytical tractability makes our model uniquely suitable as a starting point to approach the recent new open economy macroeconomic literature

regional allocation of co2 emissions allowance over provinces in china by 2020 the mitigation efforts of china are increasingly important for meeting global climate target since the rapid economic growth of china has led to an increasing share in the world s total co2 emissions this paper sets out to explore the approach for realizing china s national mitigation targets submitted to the unfccc as part of the copenhagen accord that is to reduce the intensity of co2 emissions per unit of gdp by 40 45 by 2020 as well as reducing the energy intensity and increasing the share of non fossil fuel consumption through regional allocation of emission allowance over china s provinces since the realization of china s mitigation target essentially represents a total amount emission allowance allocation problem an improved zero sum gains data envelopment analysis optimization model which could deal with the constant total amount resources allocation is proposed in this study by utilizing this model and based on several scenarios of china s economic growth co2 emissions and energy consumption a new efficient emission allowance allocation scheme on provincial level for china by 2020 is proposed the allocation results indicate that different provinces have to shoulder different mitigation burdens in terms of emission intensity reduction energy intensity reduction and share of non fossil fuels increase

how can china reach its co2 intensity reduction targets by 2020 a regional allocation based on equity and development in late 2009 the chinese government committed to cut its carbon dioxide emissions per unit of gross domestic product gdp by 40 to 45 of 2005 levels by 2020 this has raised the issue of how to allocate the co2 reduction target regionally to meet the national reduction target to meet this objective the following aspects may be taken into consideration equity principles common but differentiated responsibilities intensity reduction target fulfillment and economic difference and reduction potential among provinces this paper selects per capita gdp accumulated fossil fuel related co2 emissions and energy consumption per unit of industrial added value as indicators for emission reduction capacity responsibility and potential respectively based on these three indicators a comprehensive index is developed and an intensity allocation model constructed as decision makers may have different preferences when allocating the reduction burden we allocate different weights to the indicators analyzing the results using cluster analysis the following aspects may also be considered together with the national regional development strategy to determine how to share the burden the reduction potential of various regions implementation potential of the plans and promotion of a highly efficient low carbon economic development model

the bundesbank s communications strategy and policy conflicts with the federal government in this paper we provide an estimate of the likelihood of conflict between the federal government and the bundesbank for the 1989 1998 period we rely on a novel proxy for the impact of public communication by bundesbank officials on the probability of conflict in addition to interest rate exchange rate money supply behavior as well as electoral influences the empirical evidence is consistent with the view that speeches by the bundesbank president dealing with inflation and economic policy are a positive source of conflict in a probabilistic sense conflict was not a constant but flared up at times of economic stress and could be exacerbated by the talking of bundesbank officials

central bank independence and macroeconomic performance some comparative evidence this note uses information on a sample of sixteen oecd countries to assess the relationship between central bank independence and macroeconomic performance as previous work suggests politically controlled central banks are more likely to pursue policies that lead to high and variable inflation however the authors find little evidence that political control of central bank policy has any impact on measures of the level or variability of growth unemployment or the ex ante real interest rate copyright 1993 by ohio state university press

political and economic determinants of interest rate behavior are central banks different i introduction do politicians manipulate the instruments of macroeconomic policy to improve their electoral prospects or in response to the preferences of their own party these questions are addressed but not yet resolved by the literature on political business cycles 1 to generate a political business cycle politicians must control the instruments of macroeconomic policy monetary policy plays an important role in the determination of inflation output and employment the objects of concern to politicians and voters yet politicians do not directly control the instruments of monetary policy in industrialized countries instead these instruments are controlled by the central banks which vary widely across countries in their degree of statutory independence we wish to examine empirically whether monetary policy is influenced by the timing of elections or a change in the party in power after controlling for unexpected changes in economic fundamentals our paper assesses therefore one aspect of independence namely whether a central bank makes monetary policy decisions without measurable political influence 2 in this study we attempt to look at what central banks actually do as opposed to what they are legislated to do to distinguish between the form and substance in discussions of central bank independence as in mayer 1976 3 our paper enlarges and improves on cowart 1978 and woolley 1983 both of whom studied the role of political factors in monetary policy for a sample of industrialized countries our methodology is to compare the responsiveness of interest rate changes to economic and political factors in seventeen countries as we discuss below there are differences in opinion about whether an interest rate variable or a monetary aggregate is a better representation of monetary policy actions we compare the results of qualitative measures of differences in central bank design e g rankings of banks in order of independence as determined by legislative criteria with the results of a quantitative comparison of differences in central bank behavior this exercise should help identify the important qualitative features in the reform of existing central banks or in the design of new central banks 4 in our empirical work the relevant relationships are estimated with a recursive vector autoregression technique to control for temporal instability in the economy between 1960 and 1990 and the endogeneity of the variables in question this methodological innovation has important consequences for the understanding of reaction functions and more generally for measuring the impact of macroeconomic shocks on monetary policy we also stress results for separate subsamples of fixed and flexible exchange rates as well as for the full sample our methodology measures the influence of politics on monetary policy relative to the choices and information actually available to the central bank when the monetary policy decision was made our study does not measure the influence of politics on the instruments of fiscal policy as in alesina et al 1991 our study also does not measure the direct influence of fiscal variables on the instruments of monetary policy although there is some evidence on this issue in for example parkin 1986 and burdekin and wohar 1990 burdekin and wohar estimate the relationships between deficits money base growth and inflation for a sample of countries and time period comparable to ours all these studies find some evidence that central banks do accommodate fiscal policy by financing deficits via money growth especially since the end of bretton woods we return to the issue of fiscal policy in considering the interpretation of our results but stress that the effects of fiscal policy are partly captured in our specifications because we measure monetary policy relative to the state of the economy 5 a brief review of the literature which measures statutory central bank independence is given in section ii

optimal interest rate smoothing this paper considers the desirability of the observed tendency of central banks to adjust interest rates only gradually in response to changes in economic conditions it shows in the context of a simple model of optimizing private sector behaviour that assignment of an interest rate smoothing objective to the central bank may be desirable even when reduction of the magnitude of interest rate changes is not a social objective in itself this is because a response of policy to irrelevant lagged variables may be desirable owing to the way it steers private sector expectations of future policy

federalism and central bank independence the politics of german monetary policy 1957 92 two channels of political control allow elected politicians to influence monetary policy first political threats to the status structure or very existence of the central bank may force central bankers to comply with politically motivated demands on monetary policy second politicians may use their powers of appointment to ensure that central bank appointees share their electoral and party political goals this paper derives the monetary policy outcomes obtained as a function of the degree of central bank independence zero partial or full and central bankers types partisans or technocrats based on a case study of the 1957 and 1992 institutional changes to the german central banking system and a regression analysis covering the period in between i argue that the formal independence of the system is protected by its embeddedness in the institutions of german federalism and by the federalist components of its decentralized organizational structure the behavioral independence of the german central bank fluctuates over time with the party control of federalist veto points the bundesbank is staffed with nonpartisan technocrats who are partially insulated from political pressures

price adjustment and exchange rate pass through abstract this paper develops a simple theoretical model that can be used to account for the determinants of exchange rate pass through to consumer prices while recent evidence has found low estimates of pass through in many countries there is little consensus on an explanation for this our paper argues that sticky prices represent a key determinant of exchange rate pass through we make this argument in two stages first holding the frequency of price change constant we show that our model calibrated to data from low inflation countries can reproduce the estimates of very low pass through for these countries the principal determinant of low pass through in this case is the slow adjustment of prices we then extend the model to allow the frequency of price change to be endogenous calibrating to a wider set of countries including both low inflation and high inflation countries we show that our model implies that exchange rate pass through is increasing in average inflation but at a declining rate performing the identical exercise on the data we find a striking correspondence between the predictions of the model and those of the data

comparing shocks and frictions in us and euro area business cycles a bayesian dsge approach this paper estimates a dsge model with many types of shocks and frictions for both the us and the euro area economy over a common sample period 1974 2002 the structural estimation methodology allows us to investigate whether differences in business cycle behaviour are due to differences in the type of shocks that affect the two economies differences in the propagation mechanism of those shocks or differences in the way the central bank responds to those economic developments our main conclusion is that each of these characteristics is remarkably similar across both currency areas copyright 2005 john wiley sons ltd

incomplete pass through and the welfare effects of exchange rate variability abstract this paper considers the implications of incomplete exchange rate pass through for optimal monetary and exchange rate policy a two country model is presented which allows an explicit derivation of welfare functions in terms of a weighted sum of the second moments of producer prices and the nominal exchange rate from a single country perspective the optimal exchange rate variance depends on the degree of pass through the size and openness of the economy the elasticity of labour supply and the volatility of foreign producer prices welfare may be decreasing or increasing in the volatility of the exchange rate

international dimensions of optimal monetary policy abstract this paper provides a baseline general equilibrium model of optimal monetary policy among interdependent economies with monopolistic firms and nominal rigidities an inward looking policy of domestic price stabilization is not optimal when firms markups are exposed to currency fluctuations such a policy raises exchange rate volatility leading foreign exporters to charge higher prices vis a vis increased uncertainty in the export market as higher import prices reduce the purchasing power of domestic consumers optimal monetary rules trade off a larger domestic output gap against lower consumer prices optimal rules in a world nash equilibrium lead to less exchange rate volatility relative to both inward looking rules and discretionary policies even when the latter do not suffer from any inflationary or deflationary bias gains from international monetary cooperation are related in a non monotonic way to the degree of exchange rate pass through

central bank behavior a positive empirical analysis abstract the central bank is analyzed as a utility maximizing unit acting in the framework of a politico economic model it derives utility from keeping the price level stable and is constrained by government the structure of the economy and the political commitment to stable exchange rates it uses a satisficing strategy concentrating on keeping conflicts with government below a certain level in the case of serious conflict the central bank follows the policy directions undertaken by government but with a time lag the complete model comprising endogenous consumer voters government and central bank is econometrically tested for germany with good results

does exchange rate stability increase trade and welfare we develop a simple general equilibrium framework to study the effect of the exchange rate system on trade and welfare an important feature of the model is deviations from purchasing power parity caused by rigid price setting in buyers currency we find the following first exchange rate stability is not necessarily associated with more trade in a simple benchmark model with separable preferences and only monetary shocks trade is unaffected by the exchange rate system consistent with most evidence second both trade and welfare can be higher under either exchange rate system depending on preferences and on the monetary policy rules followed under each system finally in general there is no one to one relationship between the levels of trade and welfare across exchange rate systems

what is wrong with taylor rules using judgment in monetary policy through targeting rules it is argued that inflation targeting is best understood as a commitment to a targeting rule rather than an instrument rule e ither ageneral targeting rule explicit objectives for monetary policy or a specific targeting rule a criterion for the forecasts of the target variables to be fulfilled essentially the equality of the marginal rates of transformation and substitution between the target variables targeting rules allow the use of judgment and extramodel information are more robust and easier to verify than optimal instrument rules and they can nevertheless bring the economy close to the socially optimal equilibrium

should inflation targeting central banks respond to exchange rate movements abstract this paper examines whether it is optimal for inflation targeting central banks to respond to exchange rate movements the paper finds that exchange rate movements can provide a signal on the developments in the economy that the central bank cannot perfectly observe the results suggest that when the degrees of exchange rate pass through and international financial integration are high it is optimal for the central bank to pay more attentions to exchange rate movements these results however depend on two conditions 1 the ability of the central bank to observe the true exchange rate process and 2 the number of real frictions in the model economy

international comparisons of pricing to market behavior this paper measures the degree of price discrimination across export destinations that is associated with exchange rate changes using u s u k german and japanese industry level data given the industries sampled more price discrimination across destinations is observed in the u k german and japanese data for industries that match across source countries however behavior is very similar across source countries furthermore destination specific price adjustment on exports to the united states from germany and japan is similar to price adjustment observed on shipments to other destinations most variation in the data appears to be related to industry copyright 1993 by american economic association
