international bargaining in the presence of global environmental change this model deals with the greenhouse effect that is to say with a problem of international pollution through a description of the bargaining process it aims to determine the different forms that may be taken by cooperation agreements between the countries involved we demonstrate in particular that under some conditions it is always possible for the countries to reach an agreement such agreements are the work of a group of so called leader countries characterized by their commitment in favour of cooperation these leader countries use transfers to induce other countries to join them but they can be insufficiently attractive to convince all the countries to cooperate so as we show in the discussion the cooperation is not necessarily total therefore the key of a common problem can be a partial cooperation and not necessarily a common cooperation

central bank design abstract starting with a blank slate how could one design the institutions of a central bank for the united states this paper explores the question of how to design a central bank drawing on the relevant economic literature and historical experiences while staying free from concerns about how the fed got to be what it is today or the short term political constraints it has faced at various times the goal is to provide an opinionated overview that puts forward the trade offs associated with different choices and identifies areas where there are clear messages about optimal central bank design

modeling international climate change negotiations more responsibly can highly simplified game theory models provide reliable policy insights abstract in a recent article in this journal entitled game theory and climate diplomacy decanio and fremstad 2013 provide an interesting treatment of a range of simple game theoretic characterizations of international climate negotiations the authors use the nash and maxi min stability definitions to analyze 25 two by two ordinal games which they recognize as possible game theoretic characterizations of climate negotiations between two players e g great powers or coalitions of states the authors main conclusion that the prisoner s dilemma might not be the best description of climate negotiations game is consistent with the findings of others who have studied two by two conflicts over natural commons bardhan 1993 madani 2010 sandler 1992 taylor 1987 nevertheless given the importance of the climate change issue as well as the potential effects of our actions on the state of the environment and the well being of future generations i would like to address some gaps in their analysis which result in it having limited usefulness for policy purposes of course all models are simplified representations of reality full of limitations essentially all models are wrong but some are useful box and draper 1987 so the practical question is how wrong do they have to be to not be useful box and draper 1987 models limitations need to be carefully considered when interpreting them or applying their results to policy but some models are too simple to provide useful policy advice

do central bank forecasts influence private agents forecasting performance versus signals focusing on a set of central banks that publish their internal macroeconomic forecasts in real time enables one to shed light on the expectations channel of monetary policy the main contribution of this paper is to assess whether central bank forecasts influence private forecasts the response is positive for inflation forecasts in sweden the uk and japan to disentangle the sources of influence of central banks two concepts are proposed endogenous influence which is due to more accurate central bank forecasts and exogenous influence which is due to central bank signals on either future policy decisions or private information original empirical evidence on the central bank forecasting performance relative to private agents is provided and estimates show that in sweden more accurate inflation forecasts generate specific central bank influence that is different from the influence from signals the publication of forecasts may therefore refer to two central banking strategies that aim to shape private expectations forecasting or policymaking

what to target inflation or exchange rate author affiliation shu lin shulin75 gmail comhaichun ye haichunye gmail com acknowledgment the authors would like to thank kent kimbrough and two anonymous referees for valuable comments 1 introductionone of the most important recent innovations in the conduct of monetary policy is inflation targeting in which a monetary authority makes public an estimated inflation rate or range and attempts to steer the actual inflation toward the target using monetary tools since its emergence in the early 1990s inflation targeting has certainly been gaining popularity over the last two decades by the end of 2006 27 countries among which 17 are developing countries had explicitly adopted this new monetary policy regime the emergence of inflation targeting has attracted substantial attention from both researchers and policymakers numerous studies have empirically evaluated the effects of adopting an explicit inflation targeting regime on a country s economic performance especially on inflation and growth while studies focusing on advanced industrial countries so far have yielded mixed results the evidence in developing countries seems to be more robust 1 batini kuttner and laxton 2005 goncalves and salles 2008 and lin and ye 2009 all find that inflation targeting significantly lowers inflation in developing countries where the credibility of the central bank has not yet been well established thus the credibility gain of adopting an explicit inflation targeting regime is substantial in addition capistran and ramos francia 2010 show that inflation targeting significantly lowers the dispersion of inflation expectations in developing countries two recent survey articles walsh 2009 and ball 2010 also concluded that inflation targeting has larger beneficial effects in developing countries than those in advanced industrial countries despite the success of inflation targeting in developing countries the more traditional exchange rate targeting framework still remains the dominant monetary policy regime in developing countries it is so popular that an influential study by calvo and reinhart 2002 finds an epidemic case of fear of floating in the developing world 2 furthermore similar to inflation targeting an exchange rate targeting regime especially a credibly enforced one is also viewed as an effective means to achieve price stability in developing countries because it serves as a nominal anchor by allowing a developing central bank to borrow credibility from a foreign monetary authority in a strict exchange rate targeting framework the targeting country s inflation rate should be equal to that of the country usually a low inflation rich country to which its exchange rate is pegged does an inflation targeting framework outperform an exchange rate targeting regime in achieving price stability in developing countries if so does this benefit come at a cost of slower growth these two important and policy related questions have not yet been examined in the literature a common feature of previous studies is that they all compare an inflation targeting regime with a very broad alternative namely a non inflation targeting regime while ignoring the substantial heterogeneity in the monetary policy regimes adopted by non inflation targeting countries a disadvantage of comparing inflation targeting with such a broad alternative is that the results may not be of direct use for policy choices the objective of this study therefore is to make the first attempt in the literature to conduct a direct empirical comparison of the emerging inflation targeting framework with the popular exchange rate targeting regime in developing countries in particular we compare the effects of these two monetary policy regimes on two key outcome variables inflation and economic growth our study is built upon three recent empirical works on the effects of inflation targeting in developing countries including batini kuttner and laxton 2005 goncalves and salles 2008 and lin and ye 2009 but we focus on directly comparing inflation targeting with exchange rate targeting

co operation and unilateral commitment in the presence of global environmental problems this paper focuses on the link between group co operation and unilateral commitment of some countries in the presence of global environmental problems we show that in case of a failure of negotiation some countries can decide to commit unilaterally and reduce their emissions we call this behaviour precautionary commitment absence of international agreement does not mean global defection from the environmental issue we also show that the emergence of a non co ordinated global co operation can result from a strategic action from the members of the coalition the insiders of the coalition create an incentive for the non members to reduce without co ordinating their emissions

the effect of inflation targeting on the behavior of expected inflation evidence from an 11 country panel abstract inflation targets were introduced in the 1990s in australia canada new zealand sweden and the united kingdom change in the behavior of expected inflation in the five targeting countries is measured in a panel that includes six non targeting countries france germany italy the netherlands japan and the united states the level of expected inflation in targeting countries falls after the announcement of targets with controls for country effects year effects ongoing inflation reduction and the business cycle neither the variability of expected inflation nor the average absolute forecast error falls after the announcement of targets with controls for the level and variability of past inflation both targeting and non targeting countries experience unexpected disinflation

does inflation targeting improve fiscal discipline abstract we explore the performances of inflation targeting it adoption in terms of fiscal discipline fd while most existing studies focus exclusively on the role of fd as a precondition for it adoption using a sample of developing and developed countries we show that it adoption exerts a positive and significant effect on fd a result robust to a wide variety of alternative specifications in addition this effect is statistically significant only in developing countries a result that may fuel the current debate regarding the relevance of it adoption in general and particularly for developing countries

central bank transparency and cross border banking abstract we analyze the effect of central bank transparency on cross border bank activities based on a panel gravity model for cross border bank claims for 21 home and 47 destination countries from 1998 to 2010 we find strong empirical evidence that a rise in central bank transparency in the destination country on average increases cross border claims using interaction models we find that the positive effect of central bank transparency on cross border claims is only significant if the central bank is politically independent and operates in a stable economic environment central bank transparency and credibility are thus considered complements by banks investing abroad

a cost adjustment heuristic for dynamic lot sizing with uncertain demand timing we define a new heuristic based on the adjustment of set up costs for the dynamic lot sizing problem when demand timing is uncertain using a range of simulated problems we compare the performance of this cost adjustment heuristic with that of a safety lead time heuristic zangwill s deterministic algorithm which ignores uncertainty and the optimal solution results show that the safety lead time heuristic works well for problems with high shortage costs and high probability of early demands but poorly in other circumstances the cost adjustment heuristic is quite robust generally exceeds the performance of the safety lead time approach and is relatively insensitive to variations in uncertainty

international transmission of inflation among g 7 countries a data determined var analysis abstract we investigate the international transmission of inflation among g 7 countries using data determined vector autoregression analysis as advocated by swanson and granger swanson n granger c 1997 impulse response functions based on a causal approach to residual orthogonalization in vector autoregressions journal of the american statistical association 92 357 367 over the period 1973 2003 we find that unexpected changes in us inflation have large effects on inflation in other countries although they are not always the dominant international factor similarly shocks to some other countries also have a statistically and economically significant influence on us inflation moreover our evidence indicates that us inflation has become less vulnerable to foreign shocks since the early 1990s mainly because of the diminished influence from germany and france

inflation targeting and inflation performance a comparative analysis this article examines how the impact of inflation targeting on inflation performance depends on the choice of country samples adoption dates time periods and methodological approaches we apply two different estimation methods difference in differences and propensity score matching for our sample of 25 advanced and 59 emerging and developing countries over the period 1985 to 2011 our findings suggest that distinguishing countries by economic development is crucial as no effect of inflation targeting is found for advanced economies whereas the results suggest a significant negative effect of inflation targeting on inflation in emerging and developing countries the results are robust to the methodology used for the analysis

stabilizing expectations at the zero lower bound experimental evidence abstract our study demonstrates how agents expectations can interact dynamically with monetary and fiscal policy at the zero lower bound we study expectation formation near the zero lower bound using a learning to forecast laboratory experiment under alternative policy regimes in our experimental economy monetary policy targets inflation around a constant or state dependent target we find that subjects expectations significantly over react to stochastic aggregate demand shocks and historical information leading many economies to experience severe deflationary traps neither quantitatively nor qualitatively communicating the state dependent inflation targets reduce the duration or severity of economic crises introducing anticipated and persistent fiscal stimulus at the zero lower bound reduces the severity of the recessions when the recovery of fundamentals is sufficiently slow participants expectations become highly pessimistic and neither monetary nor fiscal policy are effective at stabilizing the economy

on the international effects of inflation targeting abstract this study empirically examines the international effects of inflation targeting employing a variety of propensity score matching methods we find strong evidence that inflation targeting has significantly different impacts on exchange rate volatility and international reserves in different country groups it significantly increases real and nominal exchange rate stability and international reserves in developing countries but lowers them in industrial countries on average inflation targeting increases lowers reserves roughly by the size of 1 3 1 8 months of imports values in developing industrial countries the treatment effects on targeting countries current accounts are found to be insignificant in both country groups

inflation and inflation uncertainty in turkey this article investigates the relationship between inflation and inflation uncertainty and the impact of monetary policy on this relationship using monthly turkish inflation data over january 1984 to october 2005 the results from various types of garch m models indicate that higher inflation rates lead to greater inflation uncertainty on the other hand the effect of inflation uncertainty on inflation is found to be negative due to stabilization motives dominating the opportunistic incentives of monetary authorities we find strong evidence to support the view that inflation oriented monetary policy has power to reduce the inflation persistence and eliminate uncertainty

does inflation targeting affect the dispersion of inflation expectations in this paper we examine the effect of having an inflation targeting framework on the dispersion of inflation forecasts from professional forecasters we use a panel data set of 25 countries including 14 inflation targeters with 16 years of monthly information we find that the dispersion of long run inflation expectations is smaller in targeting regimes after controlling for country specific effects time specific effects the level and the variance of inflation disinflation periods and global inflation on average the full effect is not observed until the third year after implementation of inflation targeting when we differentiate between developed and developing countries the dispersion of inflation expectations after inflation targeting is smaller and statistically significant only in developing countries

some economics of global warming the greenhouse effect itself is simple enough to understand and is not in any real dispute what is in dispute is its magnitude over the coming century its translation into changes in climates around the globe and the impacts of those climate changes on human welfare and the natural environment these are beyond the professional understanding of any single person the sciences involved are too numerous and diverse demography economics biology and the technology sciences are needed to project emissions atmospheric chemistry oceanography biology and meteorology are needed to translate emissions into climates biology agronomy health sciences economics sociology and glaciology are needed to identify and assess impacts on human societies and natural ecosystems and those are not all there are expert judgments on large pieces of the subject but no single person clothed in this panoply of disciplines has shown up or is likely to this article makes an attempt to forecast the economic and social consequences of global warming due to anthropogenic greenhouse gases and attempting to prevent it

central bank transparency and the volatility of exchange rates abstract we analyze the effect of monetary policy transparency on bilateral exchange rate volatility we test the theoretical predictions of a stylized model using panel data for 62 currencies from 1998 to 2010 we find strong evidence that an increase in the availability of information about monetary policy objectives decreases exchange rate volatility using interaction models we find that this effect is more pronounced for countries with a lower flexibility of goods prices a lower level of central bank conservatism and a higher interest rate sensitivity of money demand

bond markets initiation and tax revenue mobilization in developing countries we analyze the relationship between the introduction of a sovereign bond market bm and tax revenue mobilization behavior using a large sample of 119 developing countries propensity scores matching estimations reveal that bm participation significantly fosters domestic tax revenue mobilization moreover we find that this favorable effect is sensitive to bm countries characteristics namely the stance of monetary and fiscal policies the exchange rate regime the level of economic development and the degree of financial openness and financial development finally our results show that bm participation fosters internal taxes and reduces their instability compared to international trade taxes these findings highlight the strength of bm in promoting structural reforms in developing countries through encouraging them to increase their tax effort and even by contributing to some extent to the fiscal transition process

inflation real interest rates and the bond market a study of uk nominal and index linked government bond prices this paper estimates expected future real interest rates and inflation rates from observed prices of uk government nominal and index linked bonds the estimation method takes account of imperfections in the indexation of uk index linked bonds it assumes that expected log returns on all bonds are equal and that expected real interest rates and inflation follow simple time series processes whose parameters can be estimated from the cross section of bond prices the extracted inflation expectations forecast actual future inflation more accurately than nominal yields do the estimated real interest rate is highly variable at short horizons but comparatively stable at long horizons changes in real rates and expected inflation are strongly negatively correlated at short horizons but not at long horizons

inflation targeting as a shock absorber abstract we study the characteristics of inflation targeting as a shock absorber using quarterly data for a large panel of countries to overcome an endogeneity problem between monetary regimes and the likelihood of crises we propose to study large natural disasters we find that inflation targeting improves macroeconomic performance following such exogenous shocks it lowers inflation raises output growth and reduces inflation variability compared to alternative monetary regimes this performance is mostly due to a different response of monetary policy and fiscal policy under inflation targeting finally we show that only hard but not soft targeting reaps the rewards deeds not words matter for successful monetary stabilization

the problem of global environmental protection what distinguishes global common property problems and global unidirectional externalities from the ones that arise under a single jurisdiction is that there is no global authority empowered to intervene and regulate use of global environmental resources cooperation is needed the paper discusses when cooperation is most needed and how it might be obtained cooperation might emerge from a noncooperative setting if supergames are played if the actions of any one country are explicitly contingent on the actions undertaken by other countries or if moral concerns lead countries to consider the consequences of their actions for others cooperation emerges in an explicit though limited form when countries commit to regulate themselves in signing international agreements in these cases the signatories cooperate but the agreements are self enforcing an attempt is made to relate these theoretical concepts to the practice of global environmental protection copyright 1990 by oxford university press

inflation targeting and inflation expectations in mexico in this article we analyse inflation expectations in mexico after a review of the theoretical and empirical literature we apply unit root normality and cointegration tests to the data provided by banco de mexico banxico in the survey on the expectations of the private sector economics specialists our results reject the null hypothesis of normality for inflation expectations over the period 2004 01 2011 12 the exchange rate has become one of the most relevant variables in the transmission mechanism of monetary policy in a small open economy in this regard we show the existence of a long run relationship between nominal exchange rate and interest rate where inflation expectations matter for long term dynamics

does inflation targeting help reduce financial dollarization we examine whether adopting an inflation targeting regime helps reduce financial dollarization as predicted by ize and levy yeyati s 2003 portfolio model to address the self selection problem of policy adoption we apply a variety of propensity score matching methods to a large sample of 106 developing countries for the years 1985 2004 we find strong evidence that inflation targeting has large and significant treatment effects on lowering both actual financial dollarization and the model implied minimum variance portfolio dollarization our results are robust to alternative samples and model specifications and also to control for additional factors in postmatching regressions

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

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

the role of central bank transparency for guiding private sector forecasts central banks have become remarkably more transparent over the last few decades in this paper we study the effects of this evolution focusing on whether enhanced central bank transparency lowers dispersion among professional forecasters of key economic variables we use a large set of proxies for central bank transparency in 12 advanced economies we find evidence for a sizeable effect e g by announcing a quantified inflation objective or by publishing inflation and output forecasts however there are decreasing marginal effects to increases in transparency and the disagreement among the expectations of the general public is not affected this suggests that there are possible limits to transparency

inflation targeting and relative price variability what difference does inflation targeting make author affiliation chi young choi cychoi uta eduyoung se kim acknowledgment the authors are grateful to coeditor kent kimbrough and two anonymous referees for constructive comments that helped to improve this article the authors also wish to thank steve cecchetti kang liu shin ichi nishiyama margie tieslau taka tsuruga and the seminar participants at the academia sinica national chung cheng university national sun yat sen university national taiwan university texas tech university and the university of texas at arlington for helpful comments and vikas kakkar for providing cpi data for hong kong any remaining errors are the authors 1 introductionvariability in relative prices is known to be a major channel through which inflation can induce welfare costs by impeding an efficient allocation of resources in the economy consequently substantial effort has been devoted in the literature to examining the link between relative price variability rpv and aggregate inflation although much of the existing theoretical and empirical literature points to a positive monotonic relationship newer contributions suggest that the relationship between inflation and rpv is more complicated particularly in terms of its sensitivity to the inflation regime 1the primary purpose of this study is to investigate whether the connection between inflation and rpv is influenced in an important way by the monetary policy framework chosen by a central bank specifically this article focuses on exploring whether the adoption of an inflation targeting it framework exerts any significant impact on rpv as measured by the standard deviations of sectoral inflation rates relative to the aggregate rate since it was first implemented in new zealand more than two decades ago the popularity of it has spread with some twenty five countries worldwide implementing the framework to date freedman and laxton 2009 the literature is now replete with studies pointing to reductions in both the level and the volatility of inflation in countries that have adopted it e g mishkin and schmidt hebbel 2007 2 while studies of the impact of it on aggregate inflation performance are plentiful little attention has been paid to the impact of it on rpv the question of whether and indeed how it affects rpv is an important one for several reasons first exploring the potential connection between it and rpv is a worthwhile exercise given the popularity of it as a monetary framework and the centrality of rpv to the current generation of macromodels the importance of rpv is recognized in standard new keynesian dynamic stochastic general equilibrium dsge models where the variance of relative prices is viewed as a useful summary statistic as noted by amano ambler and rebei 2007 for example in dsge models the optimal rate of target inflation and the optimal variability of inflation relative to output depend on the quantitative effects of price dispersion on macroeconomic equilibrium second answering the question helps us identify the driving force behind the change in rpv distinguishing between it adoption itself and its subsequent impact on inflation if the relationship is monotonically positive as is often believed in the literature one should expect that it adoption would bring about a decline in rpv in the same way as it has led to a decline in inflation if the relationship is more complex however the effect of it adoption on reducing rpv may hinge on the change in inflation regimes after it adoption third our answer to the question also sheds additional light on the empirical evidence for the relative effectiveness of it across different stages of development while there is strong evidence that developing countries benefit more from it than industrial countries in combating inflation and its volatility e g petursson 2004 lin and ye 2009 we are aware of no empirical research that has assessed this issue with respect to rpv

dealing with time inconsistency inflation targeting versus exchange rate targeting adopting a single instead of multiple targets can be an effective way to overcome the classic time inconsistency problem the choice of a single mandate depends on the trade openness and the credibility reduced form empirical results show as central banks become less credible they are more likely to adopt a pegged exchange rate and the tendency to peg depends on trade openness in a model with loose commitment as credibility falls either an inflation target or a pegged exchange rate is more likely to be adopted arelatively closed highly open economywould adopt an inflation target exchange rate peg

inflation targeting in latin america toward a monetary union this paper examines how monetary policy decisions in brazil regarding short term interest rates have affected the term structure of interest rates we apply an event study methodology in two distinct periods between january 2000 and august 2003 right after the implementation of the inflation targeting in brazil and between september 2003 and july 2008 the main results are 1 the surprise effects have decreased 2 the explanation power has increased in the second period indicating enhancement of monetary policy 3 market participants adjust their expectations with greater advance 4 the surprise effects of decisions on short term rates on the term structure of interest rates are now close to those found in the usa and germany but higher to those found in the uk and italy therefore the results indicate that fixed income market expectations are better adjusted to the central bank anti inflationary policy

inflation uncertainty and interest rates is the fisher relation universal this paper tests the validity of the fisher hypothesis which establishes a positive relation between interest rates and expected inflation for the g7 countries and 45 developing economies for this purpose we estimate a version of the garch specification of the hypothesis for all countries included in the sample we also test the augmented fisher relation by including the inflation uncertainty in the equation the simple fisher relation holds in all g7 countries but in only 23 developing countries there is a positive and statistically significant relationship between interest rates and inflation uncertainty for six of the g7 and 18 of the developing countries and this relationship is negative for seven developing countries

what lies beneath a time varying favar model for the uk transmission mechanism we use a time varying factor augmented var to investigate changes in the transmission mechanism of economic shocks in the uk our estimates demonstrate the importance of time variation and suggest that monetary policy shocks had a bigger impact on inflation equity prices and the exchange rate during the inflation targeting period changes in the transmission of policy shocks to bond yields point to more efficient management of long run inflation expectations finally we investigate responses of disaggregated prices with the median becoming more negative and cross sectional patterns consistent with a decrease in the role of cost channels

inflation targeting an indirect approach to assess the direct impact it is quite difficult to assess the benefits of inflation targeting it since its immediate effect will be on inflation expectations an unobserved variable due to lack of comprehensive data on inflation expectations most studies so far concentrated on the impact of it either on observable variables like output unemployment and inflation or compared post it surveys of itcountries with nonit countries in our study we focus on a yet unanswered question i e how the expectations change with the adoption of it we suggest that heterogeneous inflation expectations lead to long memory in actual inflation and it if successful should decrease this persistence by concentrating the public s expectations toward the announced target empirical results confirm our hypothesis with a reduction in inflation memory after the adoption of it in almost all eight developed countries in our sample

central bank communication and monetary policy a survey of theory and evidence over the last two decades communication has become an increasingly important aspect of monetary policy these real world developments have spawned a huge new scholarly literature on central bank communication mostly empirical and almost all of it written in this decade we survey this ever growing literature the evidence suggests that communication can be an important and powerful part of the central bank s toolkit since it has the ability to move financial markets to enhance the predictability of monetary policy decisions and potentially to help achieve central banks macroeconomic objectives however the large variation in communication strategies across central banks suggests that a consensus has yet to emerge on what constitutes an optimal communication strategy

transparency and trust the case of the european central bank abstractwe examine how the transparency of the european central bank s monetary policy affects the amount of trust that the citizens of the european union have in this institution we use nearly half a million individual responses from the european commission s eurobarometer survey from 2000 to 2011 and estimate probit regressions with sample selection we find that transparency exerts a non linear effect on trust transparency increases trust but only up to a certain point too much transparency harms trust this result is robust to controlling for a number of macroeconomic conditions financial stability transparency measures and economic and socio demographic characteristics of respondents including examining respondents in european union countries that do not use the euro and addressing clustering issues

canadian inflation targeting this paper examines the intellectual environment in canada that led to the adoption of inflation targets starting in 1991 reviews some of the canadian contributions to the vast literature on inflation targeting and presents evidence in support of the view that the implementation of inflation targeting in canada has been particularly successful when compared with the experiences of other inflation targeting countries and the us

inflation targeting is it to blame for banking system instability abstract in light of the financial crisis the practice of inflation targeting it has been blamed for authorities failure to respond to the increase in financial systemic risk and to the development of asset bubbles however utilizing a rich database containing nearly 5500 commercial banks from 70 countries among which 22 are it for the period 1998 2012 this paper argues that on average inflation targeting national banking systems i are more stable ii possess sounder systemically important banks and iii are less distressed than or at least as distressed as other banks during periods of global liquidity shortages our results are robust to a series of tests such as when we compare countries with the same legal origins or control for the delegation of bank supervision responsibility to bodies other than the central bank overall we conclude that it cannot be blamed for contributing to financial fragility

bargaining and international environmental agreements this article surveys game theoretic papers focused on the negotiation process that leads to an international environmental agreement most of the papers considered apply bargaining theory although other approaches have been considered as well among other issues the papers considered analyze the burden sharing rule that will result from a negotiation over a global public good the role of information asymmetries the impact of unilateral commitments delegation and ratification whether or not countries are going to form groups during the negotiation process and the influence of the expectation of a future bargaining process on investment decisions the basic bargaining model is optimistic as it predicts that countries will reach an efficient agreement immediately however all the developments of this model surveyed afterwards are rather pessimistic and even the basic model has perverse incentives for pre negotiation signals

financial crises lessons from history for today making use of the propensity score matching method we match earlier crises pre 2007 with currently ongoing crises post 2007 the old and new crises are matched in three dimensions the global setting in which they occurred the structure of the economy and the domestic vulnerabilities in the pre crisis period our findings suggest that the euro periphery crises share sufficient commonalities with earlier crises in their pre crisis domestic vulnerabilities the study points to two important conclusions first the euro periphery crises are composed of unique country experiences hence it will not be easily resolved with a one size fits all set of economic policies secondly while each banking crisis has its inherent uniqueness each crisis also shares sufficient commonalities with one or more of the asian 5 1996 97 crises the nordic banking crisis of the early 1990s or the japanese banking crisis of the 1990s thus the extensive knowledge accumulated through these former banking crises can help in designing recovery policies selin sayek and fatma taskin

does inflation targeting anchor long run inflation expectations evidence from the u s uk and sweden we investigate the extent to which inflation expectations have been more firmly anchored in the united kingdom a country with an explicit inflation target than in the united states a country with no such target using the difference between far ahead forward rates on nominal and inflation indexed bonds as a measure of compensation for expected inflation and inflation risk at long horizons we show that far ahead forward inflation compensation in the u s exhibits substantial volatility especially at low frequencies and displays a highly significant degree of sensitivity to economic news similar patterns are evident in the uk prior to 1997 when the bank of england was not independent but have been strikingly absent since the bank of england gained independence in 1997 our findings are further supported by comparisons of dispersion in longer run inflation expectations of professional forecasters and by evidence from sweden another inflation targeting country with a relatively long history of inflation indexed bonds our results support the view that an explicit and credible inflation target helps to anchor the private sector s views regarding the distribution of long run inflation outcomes jel e31 e52 e58

some ideas regarding reserving supplier capacity and selecting replenishment quantities in a project context abstract in this paper we consider the context of a major project whose execution takes several periods specifically we are interested in the procurement policy for a resource material commodity or engineered item that is used throughout the project two types of uncertainty are considered namely i uncertainty in the requirements period by period and ii uncertainty in the capacity period by period of the supplier providing the resource there is the possibility of paying a premium to reserve dedicated capacity that can vary from period to period hence the first group of decision variables are the capacities to reserve period by period there is typically a long lead time involved so that all the capacities must be reserved prior to the first replenishment decision the second class of decision variables encompasses the procurement quantities period of period these decisions can be made as the project progresses we present some general approaches to dealing with this complex problem as well as some important insights

inflation targeting and output inflation tradeoffs abstract this article assesses whether the adoption of inflation targeting it helps reduce the output inflation tradeoff we address the self selection problem of it policy adoption by the endogenous switching regressions and show that the output inflation tradeoffs are significantly lower in it countries not only over the whole sample but also across the developed and developing country subsamples in addition we also find strong evidence supporting the positive selection hypothesis i e countries have higher probability of adopting it are exactly those who benefit more larger reduction of output inflation tradeoff from the implementation of it additional results reveal that economies with higher trade openness lower financial openness and less flexible exchange rate regime are associated with larger tradeoff between output and inflation but the effects are only statistically significant in the it regime

inflation targeting genuine effects or publication selection bias abstract this paper uses a meta regression analysis mra to evaluate the impact of publication selection bias as for the macroeconomic effects of inflation targeting it a popular approach to implementing monetary policy documented in the existing literature using 8 059 point estimates from 113 studies we show that a significant part of the documented positive effects of it on inflation and to some extent output growth volatility is in fact due to publication selection bias in particular results pointing to lower inflation volatility and higher real gdp growth tend to be favored by researchers as well as those pointing to statistically significant macroeconomic effects however even after controlling for these two types of biases we find it to be correlated with lower inflation and higher real gdp growth differently the evidence on the it inflation volatility relationship is found to be less clear

inflation targeting in emerging economies panel evidence abstract this paper shows there is no evidence that the inflation targeting regime it improves economic performance as measured by the behavior of inflation and output growth in developing countries the control of common time effects results in less negative and less significant it impacts on inflation inflation volatility and output growth volatility than previously found in the literature additionally our analysis shows robust evidence of lower output growth during it adoption on balance although lower long run mean inflation signals that the central banks of emerging economies with inflation targeting are more inflation averse the costs of disinflation have not been lower than under other monetary regimes

on the credibility of inflation targeting regimes in latin america inflation targeting has been adopted in a set of emerging economies including eight countries in latin america the success of this regime may depend critically on the credibility of the target and the expectation that the authorities will take appropriate actions if the target is breached this paper exploits a database of inflation expectations and attempts to measure whether for a set of inflation targeters in latin america expectations are well anchored a tighter anchoring of expectations is interpreted as a gain in credibility also considered are the effects on the credibility of the regime if the inflation target is breached the results indicate that while inflation expectations have not been fully anchored over the whole sample period credibility has risen but at the same time the cost of breaching the target has grown

international co movements of real and financial economic variables this study presents a first attempt at investigating whether the international co movements of real economic activity conform to the same international co movements of financial activity this study tests the international co movements of real economic activity on the one hand and financial variables such as stock returns interest rates inflation rates and risk premiums on the other hand we employ a dynamic correlation model on data from oecd countries for the period 1980 2010 our findings demonstrate that international stock markets co react in accordance with the underlying international economic forces we also document three other results first the correlation among countries with respect to real economic activity is statistically positive but the level of this correlation is lower than that of financial variables second there is a significant increase over time in the international correlation level with respect to the financial variables finally the creation of the euro monetary union

international experiences with different monetary policy regimes any views expressed in this paper are those of the author only and not those of columbia university or the national bureau of economic research abstract this paper examines the international experiences with four basic types of monetary policy regimes 1 exchange rate targeting 2 monetary targeting 3 inflation targeting and 4 monetary policy with an implicit but not an explicit nominal anchor the basic theme that emerges from this analysis is that transparency and accountability are crucial to constraining discretionary monetary policy so that it produces desirable long run outcomes because the devil is in the details in achieving transparency and accountability what strategy will work best in a country depends on its political cultural and economic institutions as well as on its past history

how have inflation targeting central banks responded to supply shocks abstract this paper examines how inflation targeting central banks have responded to supply shocks based on the sign restriction var approach it is found that inflation targeting central banks have become accommodative to adverse supply shocks following the adoption of inflation targeting

inflation targeting in colombia 2002 2012 proquest denotes formulae omitted over the last twenty years nearly thirty countries have adopted inflation targeting regimes to conduct monetary policy in addition to the announce ment of specific inflation targets inflation targeting regimes have been characterized by increased transparency enhanced communication with the public and explicit accountability mechanisms moreover their policy strategy is based on setting short run interest rates rather than on targeting monetary aggregates in principle inflation targeting regimes also increase exchange rate flexibility the performance of inflation targeting regimes has been a matter of exten sive research for instance ball and sheridan and lin and ye conclude that in industrialized countries inflation targeting did not make a difference in inflation and output behavior 1 the spirit of these conclusions is echoed in two recent surveys on the performance of inflation targeting 2 another line of research on inflation targeting in industrialized countries studies its impact on sacrifice ratios output losses per point of inflation during monetary driven disinflations according to proponents inflation targeting anchors inflation expectations and it should thus allow for less costly disinflation processes while goncalves and carvalho find strong evidence supporting this hypoth esis in developed countries brito shows that the results are not robust to the inclusion of time effects 3 de roux and hofstetter conclude that inflation targeting allows for less costly disinflations even when controlling for time effects but only if disinflations are slow 4 for fast disinflations it does not yield less costly disinflations for developing countries the evidence is less conclusive goncalves and salles find that inflation targeting allows for a greater reduction in inflation and lower output volatility a result confirmed by lin and ye 5 brito and bystedt however suggest that the greater inflation reduction came at the expense of poorer output growth 6 in the surveys walsh concludes that evidence on inflation targeting in developing countries is clearly favorable to the regime while ball is more skeptical calling the outcomes inconclusive 7more recently de carvalho filho shows that during the recent global finan cial crisis inflation targeting nations outperformed non inflation targeting nations on several dimensions for both developed and developing economies their policy response was more aggressive they allowed the exchange rate to more effectively absorb the shocks and they recorded a stronger macro economic performance output industrial production and unemployment 8the vast empirical literature comparing performance across different mon etary regimes stands in contrast to the relatively scant research on the tools strategies goals and dilemmas faced by inflation targeting central banks espe cially in developing countries while there is good information on the overall comparative performance of these regimes little information is available on the political economy dimensions the increasing variety of instruments and goals of inflation targeting central banks and the challenges that lie ahead for them in this paper we fill part of this gap by examining the experience of the cen tral bank of colombia banco de la republica over the last decade a period of consolidation and innovation of its inflation targeting strategy colombia is one of five large latin american economies that have well established inflation targeting regimes along with brazil chile mexico and peru all of these countries adopted inflation targeting more than ten years ago yet their performance tools and goals have not been extensively studied cen tral banks in the region have used a variety of tools beyond short run policy interest rates including liquidity and reserve requirements credit provisions capital controls and interventions in the foreign exchange markets

is inflation targeting a good remedy to control inflation abstract since the 1990s inflation targeting it has been adopted by several central banks as a strategy for monetary policy it is expected that the adoption of this monetary regime can reduce inflation and inflation volatility this article is concerned with these issues and makes use of the propensity score matching methodology on a sample of 180 countries for the period from 1990 to 2007 for analysis the sample is split into two sets of countries advanced and developing the findings suggest that the adoption of it is an ideal monetary regime for developing economies and in addition to reducing inflation volatility can drive inflation down to internationally acceptable levels regarding advanced economies the adoption of it does not appear to represent an advantageous strategy in brief the empirical results indicate that the adoption of it is useful for countries that must enhance their credibility for the management of monetary policy

does inflation targeting really make a difference evaluating the treatment effect of inflation targeting in seven industrial countries abstract we evaluate the treatment effect of inflation targeting in seven industrial countries that adopted this policy in the 1990s to address the self selection problem of policy adoption we make use of a variety of propensity score matching methods recently developed in the treatment effect literature our results show that inflation targeting has no significant effects on either inflation or inflation variability in these seven countries further evidence from long term nominal interest rates and income velocity of money also supports the window dressing view of inflation targeting

bilateral or multilateral bargaining in the face of global environmental change this model deals with the problem of the greenhouse effect a problem of transfrontier pollution it consists of determining through the description of a bargaining process the conditions under which it is preferable for the developing countries to speak with a united voice and those conditions under which it is preferable for them to negotiate separately one from the other in particular it is shown that the agreements arising from the bargaining cannot be equitable and for that reason they include only a limited number of countries

does inflation targeting make a difference in developing countries we evaluate the treatment effect of inflation targeting in thirteen developing countries that have adopted this policy by the end of 2004 using a variety of propensity score matching methods we show that on average inflation targeting has large and significant effects on lowering both inflation and inflation variability in these thirteen countries however the effectiveness of inflation targeting on lowering inflation is found to be quite heterogeneous the performance of a given inflation targeting regime can be affected by country characteristics such as government s fiscal position central bank s desire to limit the movements of exchange rate its willingness to meet the preconditions of policy adoption and the time length since the policy adoption

coordination versus prisoners dilemma implications for international cooperation and regimes the study of political institutions in general and international cooperation in particular has been beneficially influenced by the prisoners dilemma pd game model but there is a mistaken tendency to treat pd as representing the singular problem of collective action and cooperation by relaxing the assumptions of 2 2 games and developing an alternate model of the coordination game i show how some cooperation problems have very different properties from those found in pd the analytical results of the two games are compared across several important dimensions number of strategies available number of iterations of the game numbers of players and the distribution of power among them the discussion is illustrated with specific problems of international cooperation and the implications of alternative cooperation problems for the formation and performance of international regimes are explored the basic solutions for pd and coordination have divergent ramifications for the institutionalization stability and adaptability of regimes and for the role of hegemony in the international system however the coordination model does not replace the pd model but complements and supplements it as a way to understand the diversity of political institutions these results are widely applicable to areas of politics beyond international relations

is financial inclusion good for bank stability international evidence abstract financial inclusion has become an important public policy priority following the recent global financial crisis yet we know very little of how it impacts soundness of the providers of financial services using an international sample of 2635 banks in 86 countries over the period 2004 12 we find that higher level of financial inclusion contributes to greater bank stability the positive association is particularly pronounced with those banks that have higher customer deposit funding share and lower marginal costs of providing banking services and also with those that operate in countries with stronger institutional quality the results are robust to instrumental variables analysis controlling for bank fixed effects alternative measures of financial inclusion among several other robustness tests our results highlight that the importance of ensuring inclusive financial system is not only a development goal but also an issue that should be prioritised by banks as such a policy drive is good for their stability

currency unions and trade how large is the treatment effect currency unions and trade what can the data say the impact of a common currency on trade can be grossly mismeasured if countries that belong to currency unions are systematically different from those that do not and if the relationship between trade and its observable determinants is complex i argue that such complications are plausible and likely to distort the empirical results of a recent economic policy paper by andrew rose issue 30 2000 pp 7 45 using techniques designed to be robust in this situation i find that the effects of common currency on international trade are considerably less dramatic and much less precisely estimated torsten persson i have always maintained that the measured effect of a single currency on trade appears implausibly large but i am not convinced by torsten persson s diagnosis and proposed solution i apply a variety of estimation techniques to a new larger data set where many more instances of currency union creation and abandonment make it possible to rely on time series as well as cross sectional evidence the results are similar to my earlier ones the effect of a single currency on trade is large andrew rose

re evaluating the effectiveness of inflation targeting abstract this paper estimates the treatment effect of inflation targeting on macroeconomic variables using a semiparametric single index method by taking into account the model misspecification of parametric propensity scores our study uses a broader set of preconditions for inflation targeting and macroeconomic outcome variables than the existing literature the results suggest no significant difference in the inflation level and inflation volatility between targeters and non targeters after the adoption of inflation targeting we find that inflation targeting reduces sacrifice ratio and interest rate volatility in the developed economies and that it enhances fiscal discipline in both the industrial and developing countries

inflation targeting and the forward bias puzzle in emerging countries abstract based on quarterly data on 31 emerging countries among which 16 are inflation targeting countries from 1990q1 to 2014q3 we obtain a strong support for the conjecture that the implementation of inflation targeting weakens the fisherian relation between expected depreciation and the interest rate differential uncovered interest parity condition and thus is conducive to the appearance of the forward bias puzzle in emerging countries we show that this reflects the performance of inflation targeting regimes in lowering the level and volatility of inflation our finding holds when controlling for country specific effects time specific effects global disinflation exchange rate management crises and using different econometric techniques

an assessment of inflation targeting in a quantitative monetary business cycle framework evidence from four early adopters this article examines the effectiveness of inflation targeting it to stabilize the real economy in advanced countries where it was adopted in the early 1990s to quantitatively assess it this article employs the monetary business cycle accounting methodology recently developed by sustek 2011 which is an extended version of chari kehoe and mcgrattan 2007 to monetary models our main finding is that the monetary policy wedge that captures economic fluctuations caused by monetary policy has significantly declined since the implementation of it in the early 1990s the results suggest that advanced economies such as australia canada sweden and the united kingdom that adopted it in the early 1990s have been successful in stabilizing business cycle fluctuations

inflation targeting makes the difference novel evidence on inflation stabilization abstract though svensson 1997 svensson 2003 provides theoretical evidence that the introduction of inflation targeting is consistent with an inflation stabilizing monetary policy empirical evidence that the introduction of inflation targeting actually changes central bank s behavior is still missing this paper aims to close this gap and estimates forward looking monetary policy rules for 20 inflation targeting countries to this end we use a data set which is available to the central bank in real time published on a frequently basis comparable among all countries and which includes the periods before and after the introduction of inflation targeting we find that the introduction of inflation targeting significantly shifts the central bank s reaction function toward inflation stabilizing we also provide evidence of time varying effects and find that central banks stabilize inflation once inflation targeting is introduced we take our results as strong evidence that the introduction of inflation targeting makes the difference for monetary policy strategies

directional analysis of consumers forecasts of inflation in a small open economy evidence from south korea abstractwe evaluate the directional accuracy of consumers forecasts of inflation in predicting the movement of the actual cpi in a small open economy in order to do so we use a method developed by pesaran and timmermann 2009 based on south korean data by illustrating an application of the new market timing test we show that consumers expectations of inflation are not a useful predictor of the cpi in south korea our findings suggest that the directional accuracy of consumers 1 year ahead forecasts of inflation is not affected by the inflation targeting of the bank of korea our findings also suggest that consumers 1 year ahead forecasts of inflation are scattered away from the bank of korea s inflation target

dynamic lot sizing when demand timing is uncertain we characterize optimal solutions for the dynamic lot sizing problem when demand quantities are known but their timing is uncertain the characterization states that for some possible history of demands following a period of production there is a period with zero inventory before another period with production using this characterization we outline a dynamic program for the solution of these problems some results from sample problems illustrate the variety of optimal solutions that can occur

the implications of central bank transparency for uncertainty and disagreement abstract using survey data from 25 economies we provide evidence that greater transparency surrounding monetary policy reduces uncertainty of interest rates and inflation primarily by reducing uncertainty that is common to agents rather than disagreement between agents this suggests that studies that focus on disagreement as a proxy for uncertainty understate the benefits of monetary policy transparency the adoption of inflation targets and forward guidance are both associated with lower uncertainty although inflation targets have a stronger impact on reducing uncertainty than forward guidance moreover there are diminishing benefits from ever higher levels of transparency taken as a whole our results support the contention that clarity of communication is as important as the magnitude of transparency

note a note on the dynamic lot size model with uncertainty in demand and supply processes in this paper we give some extensions of a result of nevison and burstein nevison c h m burstein 1984 the dynamic lot size model with stochastic lead times management sci 30 100 109 who discuss a dynamic lot sizing model with stochastic lead times they consider a situation in which the lead time distribution is unaltered by the amount which is ordered but is otherwise arbitrary and characterize the optimal solution in terms of points at which there is zero inventory here we give a more precise characterization and show that these results can be extended to a situation in which the demands are also stochastic and in which there is uncertainty relating to quantity as well as to the timing of demands and order arrivals the method of proof that we use is different from that used by nevison and burstein

north south negotiations on emission reductions a bargaining approach this article models north south negotiations on emission reductions where the north provides side payments in exchange for the south s adoption of a more stringent emission standard we find that depending on where firms compete strong asymmetry among regions the two regions different valuations of side payments and climate change damage can produce self enforcing cooperative agreements moreover the south s optimal standard choice can be one of two polar cases i e either the cleanest or the dirtiest irrespective of the continuum of standards available the results above can also hold true when both parties bargain over the south s emission tax

testing the transparency benefits of inflation targeting evidence from private sector forecasts abstract using inflation forecast data for 11 it adoption countries it adoption is found to promote convergence in forecast errors suggesting that it enhances transparency this result which is subjected to several robustness checks and found to be robust supports morris and shin s 2002 contention that better public information is most beneficial for forecasters with bad private information however it does not support their hypothesis that better public information could make private forecasts less accurate

can more public information raise uncertainty the international evidence on forward guidance abstract central banks have used different types of forward guidance this paper reports cross country evidence showing that in general forward guidance mutes the response of government bond yields to macroeconomic news however calendar based guidance with a short horizon counter intuitively raises it using a stylized model where agents learn from market signals it shows that the public release of more precise information about future rates lowers the informativeness of market signals and as a consequence may increase uncertainty and amplify the reaction of expectations to macroeconomic news

dynamic version of the economic lot size model this article originally appeared in management science october 1958 volume 5 number 1 pp 89 96 published by the institute of management sciences a forward algorithm for a solution to the following dynamic version of the economic lot size model is given allowing the possibility of demands for a single item inventory holding charges and setup costs to vary over n periods we desire a minimum total cost inventory management scheme which satisfies known demand in every period disjoint planning horizons are shown to be possible which eliminate the necessity of having data for the full n periods

sequential bargaining with incomplete information this paper describes a simple two person two period bargaining game and solves it using the concept of perfect bayesian equilibrium in which the actions of each player convey information which is used by his opponent the paper examines the effects of changes in bargaining costs the size of the contract zone and the length of the bargaining process on such aspects of the solution as the probability of impasse and the likelihood of concessions the combination of information transfer and the lack of pre commitment embodied in perfectness yields many surprising results common perceptions about the effects of parameter changes on bargaining processes are suspect and should be checked in the particular game being discussed

the incredible volcker disinflation abstract the reduction in inflation that occurred in the early 1980s when the federal reserve was headed by paul volcker is arguably the most widely discussed and visible macroeconomic event of the last 50 years of u s history inflation had been dramatically rising but under volcker the fed first contained and then reversed this process using a simple modern macroeconomic model we argue that the real effects of the volcker disinflation were mainly due to its imperfect credibility in our view the observed upward volatility and subsequent stubborn elevation of long term interest rates during the disinflation are key indicators of that imperfect credibility studying transcripts of the federal open market committee recently released to the public we find to our surprise that volcker and other fomc members likewise regarded the long term interest rates as indicative of inflation expectations and of the credibility of their disinflationary policy drawing from the transcripts and other contemporary sources we consider the interplay of monetary targets operating procedures and credibility during the volcker disinflation

fiscal rules and government borrowing costs international evidence we find that the adoption of numerical fiscal rules reduces government borrowing costs in a sample of 101 advanced and developing countries for 1985 2010 we apply a variety of propensity score matching methods to address the self selection problem of policy adoption and find strong evidence that fiscal rules have large and significant treatment effects on lowering government borrowing costs in both international and domestic financial markets the results are robust to changes in country sample and alternative estimation methodology and are consistent with fiscal rules helping to build policy credibility by reducing the probability of default and the risk premium on government debt that compensates lenders for this possibility jel e43 g12 h60

the role of inflation targeting in international debt denomination in developing countries abstract this paper analyzes the inflation targeting experience of developing countries as an effective monetary policy framework to promote changes in the currency composition of their international debt using matching with difference in differences to address the self selection bias we find that inflation targeting has led to a 3 6 percentage point reduction in the foreign currency share of international debt in targeting countries when compared to non targeting countries with the effect especially pronounced for sovereign international debt differentiating by type of owner we find a reduction of the foreign currency share in foreign held total sovereign debt but no effect on domestic held debt furthermore from the analysis of the us dollar and euro shares we find that inflation targeting has contributed to a 9 percentage points lower dollar share in international debt in targeting countries compared to non targeting countries while the effect on the euro share is negligible this not only provides evidence that the structural features of international financial markets matter but also that monetary policy can help developing countries reduce their reliance on foreign currency debt especially if it is held by foreign investors

the first year of the eurosystem inflation targeting or not this paper is a brief evaluation of the eurosystem s monetary policy regime after its first year in particular of the extent to which it is similar to inflation targeting as practiced by an increasing number of central banks i examine the eurosystem s goals framework for monetary policy decisions and communication with outsiders criteria for evaluation are whether the goals are unambiguous and appropriate whether the decision framework is efficient in collecting and processing information and reaching decisions that are appropriate relative to the goals and whether the communication is effective in motivating decisions simplifying external evaluation and thereby improving transparency and accountability i also consider whether the actual instrument setting has been appropriate given the informaion available at the times of decision

the modern history of exchange rate arrangements a reinterpretation we develop a novel system of reclassifying historical exchange rate regimes one key difference between our study and previous classifications is that we employ monthly data on market determined parallel exchange rates going back to 1946 for 153 countries our approach differs from the imf official classification which we show to be only a little better than random it also differs radically from all previous attempts at historical reclassification our classification points to a rethinking of economic performance under alternative exchange rate regimes indeed the breakup of bretton woods had less impact on exchange rate regimes than is popularly believed
