monetary policy rules in the open economy effects on welfare and business cycles abstract this paper computes welfare maximizing taylor style interest rate rules in a business cycle model of a small open economy the model assumes staggered price setting and shocks to domestic productivity to the world interest rate to world inflation and to the uncovered interest rate parity condition optimized policy rules have a pronounced anti inflation stance and entail significant nominal and real exchange rate volatility the country responds to an increase in external volatility by holding more foreign assets the policy rule affects the variance and the mean of consumption the effect on the mean matters significantly for welfare

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

inflation price level and hybrid rules under inflation uncertainty the performance and robustness of optimised interest rate rules are analysed in a new keynesian model estimated for the euro area economy in particular we examine the properties of rules responding to inflation the price level or a combination of the two a hybrid rule all the rules also respond to the output gap the optimal hybrid rule is only marginally superior when there is no model uncertainty when there is uncertainty about the degree of inflation persistence the inflation rule is the most robust rule and the performance of the other two rules deteriorates however all the rules perform well if the true degree of inflation persistence turns out to be less than policymakers estimate

ppp exchange rate rules macroeconomic in stability and learning in order to maintain competitiveness governments in developing economies seem to have pursued purchasing power parity ppp exchange rate rules by adjusting the nominal devaluation rate in response to real exchange rate deviations from an intermediate target this article shows that these rules are likely to induce macroeconomic instability as they generate sunspot driven fluctuations that are in fact learnable by agents in the expectational stability sense it finds that the existence of these learnable sunspots depends among others on open economy features including the degree of openness and the degree of exchange rate pass through to consumer s import prices

conservative central banks and nominal growth exchange rate and inflation targets a framework is developed in which inflation biases with different target variables are compared a nominal growth target measured in consumer prices may yield less stabilization bias than a nominal income growth target exchange rate and inflation targets result in less stabilization bias than an income growth target the more important the terms of trade stabilization persistence in output causes excessive stabilization of productivity shocks and of shocks to the terms of trade under discretion an inflation weight conservative central bank is more likely under an inflation target than under an exchange rate target and less likely under a nominal income growth target

the butterfly effect of small open economies abstract the rational expectations equilibrium of a small open economy can be subject to indeterminacy if foreign monetary policy does not satisfy the taylor principle we study the implications of foreign induced indeterminacy in the two country version of the sticky price small open economy model our main finding is that smallness is a property of the unique rational expectations equilibrium of the large economy and not a general property of the small open economy model if the large economy fails to anchor expectations shocks to the small economy can affect the large one this form of indeterminacy gives rise to a butterfly effect additional assumptions are required to preserve the smallness of the small economy

theoretical analysis regarding a zero lower bound on nominal interest rates this paper explores several issues concerning a possible zero lower bound zlb including its theoretical rationale the magnitude of effects of low sustained inflation on real interest rates the validity of analyzing monetary policy in models with no monetary variables and the dynamic stabilizing properties of taylor rules in a zlb context the most important argument however is that if the short nominal rate is immobilized at zero there nevertheless exists a route for monetary stabilization policy to be effective via the foreign exchange market its quantitative importance is examined in a calibrated optimizing open economy model

could a monetary base rule have prevented the great depression abstract this paper continues an ongoing investigation of the properties of a policy rule that specifies settings of the monetary base that are designed to keep nominal gnp growing smoothly at a noninflationary rate counterfactual historical simulations for 1923 1941 are conducted with the rule and a small model of nominal gnp determination estimated with u s quarterly data with residuals fed in as estimates of the behavioral shocks that occurred the simulation results indicate that nominal gnp would have been kept reasonably close to a steady three percent path over 1923 1941 if the rule had been in effect

ricardo s international trade theory beyond the comparative cost example that the labour embodied in the export goods given in exchange for one unit of the imported good is less than the labour which the country would have to utilise if it itself were to produce one unit of the imported good there is no question that this ricardian model based on the example of england and portugal trading cloth for wine in chapter 7 of ricardo s principles of political economy and taxation 1951a is an excellent pedagogical device to illustrate the role of compara tive advantage in determining a country s trade pattern and the resulting gains from trade ricardo showed that trade enhances a country s welfare even though it may be more efficient than its trading partner in producing each of its commodities as long as its relative productivity advantage differs between them the principle of comparative advantage

monetary policy and exchange rate volatility in a small open economy we lay out a small open economy version of the calvo sticky price model and show how the equilibrium dynamics can be reduced to a simple representation in domestic inflation and the output gap we use the resulting framework to analyse the macroeconomic implications of three alternative rulebased policy regimes for the small open economy domestic inflation and cpi based taylor rules and an exchange rate peg we show that a key difference among these regimes lies in the relative amount of exchange rate volatility that they entail we also discuss a special case for which domestic inflation targeting constitutes the optimal policy and where a simple second order approximation to the utility of the representative consumer can be derived and used to evaluate the welfare losses associated with the suboptimal rules

stabilising properties of discretionary monetary policies in a small open economy this article sets out a simple new keynesian open economy model and shows that the conduct of discretionary monetary policy in an open economy differs substantially from the closedeconomy framework the article shows analytically that the existence of the direct exchange rate channel in the open economy phillips curve impairs the perfect stabilising property of monetary policy in the face of demand side disturbances under domestic inflation targeting if cpi inflation is instead the target then the perfect stabilising property of monetary policy breaks down even in the absence of the direct exchange rate channel in the phillips curve

price stability in open economies this paper studies the conditions under which price stability is the optimal policy in a two country open economy model with imperfect competition and price stickiness special conditions on the levels of country specific distortionary taxation and the intratemporal and intertemporal elasticities of substitution need to be satisfied these restrictions apply to both cooperative and non cooperative settings most importantly we show that cooperative and non cooperative solutions do not coincide despite market completeness and producer currency pricing in this framework our analysis suggests a role for international policy coordination

misselling through agents this paper analyzes the implications of the inherent conflict between two tasks performed by direct marketing agents prospecting for customers and advis ing on the product s suitability for the specific needs of customers when structuring salesforce compensation firms trade off the expected losses from misselling unsuitable products with the agency costs of providing market ing incentives we characterize how the equilibrium amount of misselling and thus the scope of policy intervention depends on features of the agency problem including the internal organization of a firm s sales process the transparency of its commission structure and the steepness of its agents sales incentives jel m31 m37 m52 when purchasing unfamiliar products consumers often rely on information and advice pro vided by representatives of the seller this creates the possibility of misselling the question able practice of a salesperson selling a product that may not match a customer s specific needs 1 this problem is particularly severe in markets for technically complex products such as con sumer electronics auto repairs medical care and retail financial services including securities pensions insurance policies and mortgages an important feature of these markets is that the seller often deals with the customer through an agent rather than directly for example financial brokers typically recommend purchase of a specific product after inquiring about their customers particular circumstances and needs the possibility of abuse has led to regulation in some of these markets most notably for securities transactions the financial industry regulatory authority finra the major self regulatory organization for securities firms operating in the united states mandates that broker dealers make a reasonable effort to obtain information about the individual characteristics of their noninstitutional cus tomers and to ensure that their recommendations are suitable to customers financial situations

price level targeting and stabilisation policy a survey this paper surveys recent articles on the costs and benefits of price level targeting focusing its use as a tool for stabilisation policy it discusses how price level targeting can affect the short run trade off between output and inflation variability by influencing inflation expectations it reviews how assigning an explicit price level target to a central bank that is unable to commit to its future policies can improve economic performance it surveys other potential benefits and costs among the costs it underlines the importance of perfectly rational expectations for the optimality of price level targeting and an exacerbation of the time inconsistency problem

average inflation targeting the analysis of this paper demonstrates that when the phillips curve has forward looking components a goal for average inflation i e targeting a j period average of one period inflation rates will cause inflation expectations to change in a way that improves the short run trade off faced by the monetary policymaker average inflation targeting is thus an example of a modified loss function which when implemented in a discretionary fashion results in more efficient outcomes from the standpoint of the true social objective inflation targeting under commitment than the discretionary pursuit of the true objective itself in purely forward looking models average inflation targeting is dominated by price level targeting but we also demonstrate in a micro founded model where the phillips curve has both forward and backward looking components that there are cases when the average inflation target provides more efficient outcomes than both ordinary one period inflation targeting and price level targeting

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

price level targeting vs inflation targeting a free lunch price level targeting without base drift and inflation targeting with base drift are compared under commitment and discretion with persistence in unemployment price level targeting is often said to imply more short run inflation variability and thereby more employment variability than inflation targeting counter to this conventional wisdom under discretion a price level target results in lower inflation variability than an inflation target if unemployment is at least moderately persistent a price level target also eliminates the inflation bias under discretion and as is well known reduces long term price variability society may be better off assigning a price level target to the central bank even if its preferences correspond to inflation targeting a price level target thus appears to have more advantages than commonly acknowledged

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

real wage rigidities and the new keynesian model most central banks perceive a trade off between stabilizing inflation and stabilizing the gap between output and desired output however the standard new keynesian framework implies no such trade off in that framework stabilizing inflation is equivalent to stabilizing the welfare relevant output gap in this paper we argue that this property of the new keynesian framework which we call the divine coincidence is due to a special feature of the model the absence of nontrivial real imperfections we focus on one such real imperfection namely real wage rigidities when the baseline new keynesian model is extended to allow for real wage rigidities the divine coincidence disappears and central banks indeed face a trade off between stabilizing inflation and stabilizing the welfare relevant output gap we show that not only does the extended model have more realistic normative implications but it also has appealing positive properties in particular it provides a natural interpretation for the dynamic inflation unemployment relation found in the data

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

optimal horizons for inflation targeting abstract in this paper we investigate the problem of selecting an optimal horizon for inflation targeting in the united kingdom since there are two key ways of thinking about an optimal horizon we look at optimal horizons for both of these interpretations in addition to see whether our results are robust in the face of model uncertainty we compute optimal horizons for two different models with divergent structural and dynamic characteristics

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

optimal monetary policy with international trade in intermediate inputs abstract this paper examines optimal monetary policy in a two country new keynesian model with international trade in intermediate inputs we derive the loss function of a cooperative monetary policymaker and find that the optimal monetary policy must target intermediate goods price inflation rates final goods price inflation rates final goods output gaps and relative price gaps we use the welfare loss under the optimal monetary policy as a benchmark to evaluate the welfare implications of three taylor type monetary policy rules a main finding is that the degree of price stickiness at the stage of intermediate goods production is a key factor to determine which policy rule should be followed specifically when the degree of price stickiness at the stage of intermediate goods production is high the policymaker should follow intermediate goods ppi based taylor rule whereas cpi based taylor rule should be followed when the degree of price stickiness at the stage of intermediate goods production is intermediate or low

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

north south trade and capital flows in a ricardian model of accumulation abstract a class based asymmetric general equilibrium model of the world economy is developed to trace the trajectory of the north south terms of trade the world profit rate the northern real wage and the level of southern employment in the presence of capital accumulation and technical progress it is shown that i accumulation must be accompanied by a continuing deterioration in the terms of trade of the south and may entail a cumulative contraction in its level of employment and ii technical progress in the south will of necessity produce a long run worsening of its terms of trade and assuming world demand for southern goods is priceinelastic of its level of unemployment

the un importance of forward looking behavior in price specifications the seminal work of edmund s phelps 1978 john b taylor 1980 and guillermo a calvo 1983 developed forward looking models of price determination that imparted inertia to the price level these models incorporate expectations of future prices and excess demand by imposing constraints typically lag lead symmetry constraints that force future variables to enter the specification in this paper the author tests the empirical significance of future prices in specifications like those of taylor he finds that expectations of future prices are empirically unimportant in explaining price and inflation behavior however the dynamics of a model that includes a purely backward looking inflation specification differ substantially and not altogether pleasingly from those with a forward looking specification copyright 1997 by ohio state university press

crucial issues concerning central bank independence abstract this paper argues first that it is inappropriate to presume that central banks will in the absence of any tangible precommitment technology inevitably behave in a discretionary fashion that implies an inflationary bias furthermore there is no necessary tradeoff between flexibility and commitment second to the extent that the absence of any precommitment technology is nevertheless a problem it will apply to a consolidated central bank plus government entity as well as to the central bank alone thus contracts between governments and central banks do not overcome the motivation for dynamic inconsistency they merely relocate it several implications are discussed

misselling financial products the limits for internal compliance abstract a firm advises customers through an agent such as a mortgage broker who is incentivized through commissions and the threat of firing we show that this implies an upper boundary for the feasible standard of advice up to which the standard increases with commissions

from stationary state to endogenous growth international trade in the mathematical formulation of the ricardian system in his 1814 15 correspondence with malthus and in his essay on profits ricardo championed the free importation of wage goods as a highly effective growth enhancing policy in order to capture this aspect in the mathematical formulation of the ricardian system first introduced by pasinetti in 1960 in the context of a closed economy we produce a variant of that model where the economy is a small open one we show that this economy is characterised by endogenous growth since the growth rate is bounded from below and we locate two thresholds concerning the allocation of labour among the two sectors of the economy and the pattern of international trade

europe s industrialization and colonial underdevelopment in the light of ricardo s corn model abstract the paper discusses the dynamics of sectoral resource allocation in an extension of ricardo s corn model to a north south world system it is shown that free trade and capital mobility in the presence of capital accumulation must entail in the flexible wage metropolis a secular shift of resources out of agriculture into manufacturing accompanied by real wage growth in the labor surplus colonies a necessary expansion of commerical agriculture but an ambiguous evolution of manufacturing output and employment giving rise to the possibility of a secular contraction in overall colonial market employment

the links between international parity conditions and granger causality a study of exchange rates and prices this article investigates granger causality between exchange rates and prices for the us and four of its trading partners canada germany japan and the uk we emphasize the distinction between direct and indirect granger causality exchange rates directly cause prices if movements in exchange rates lead movement in prices and exchange rates indirectly cause prices if deviations from the purchasing power parity ppp condition can help forecast movement in prices but only by including the interest rate differential in our error correction model do we obtain results that align with economic theory the economic theory of ppp suggests that exchange rates and prices are cointegrated with exchange rates moving proportionally to prices in the long run in general we find either direct or indirect feedback mechanisms between exchange rates and prices

inflation persistence and robust monetary policy design this paper examines the performance of optimised interest rate rules when there is uncertainty about a key determinant of the monetary transmission mechanism namely the degree of persistence characterising the inflation process the paper focuses on the euro area and utilises two variants of an estimated small scale macroeconomic model featuring distinct types of staggered contracts specifications which induce quite different degrees of inflation persistence the paper shows that a cautious monetary policy maker is well advised to design and implement interest rate policies under the assumption that inflation persistence is high when there is considerable uncertainty about the prevailing degree of inflation persistence such policies are characterised by a relatively aggressive response to inflation developments and exhibit a substantial degree of inertia

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

optimal monetary policy and the role of hybrid inflation price level targets this study investigates the role of hybrid inflation price level targets as a solution to the well known stabilization bias problem that arises under discretionary policies the analysis shows that social welfare will be improved by employing a weighted average of inflation and price level as one of the central bank s target variables in addition to the output gap growth target the reason is that imposing the optimal hybrid target will reduce inflation variability in a highly efficient way in particular the optimal hybrid regime outperforms other previously suggested regimes when the degree of inflation persistence is moderate

should central banks target consumer prices or the exchange rate in this article we consider two arguments suggesting that monetary authorities in an open economy should target output price inflation and not consumer price inflation the first suggests that output price inflation corresponds to the distortions caused by price rigidity the second shows how policy rules involving consumer price inflation can induce instability because of the feedback from interest rates to consumer price inflation via the exchange rate we examine both arguments in the context of an open economy which is subject to a range of shocks we show that both arguments remain robust but that there is a case for including a terms of trade or real exchange rate gap term in the authorities welfare function alongside the output gap and output price inflation

hybrid inflation and price level targeting in this paper we investigate the properties of monetary regimes that combine price level and inflation targeting we look both at an optimal control and at a simple rule characterisation of these regimes we derive numerical results by modelling the economy as a small scale open economy re model calibrated on uk data we conclude that 1 the relative merits of price level and inflation targeting as well as of mixes of these two depend on particular modelling and policy assumptions and 2 these merits do not always change gradually and or monotonically as we move from one regime to another

optimal monetary policy with relative price distortions this paper analyzes optimal monetary policy in a sticky price model with calvo type staggered price setting in the paper the optimal monetary policy maximizes the expected utility of a representative household without having to rely on a set of linearly approximated equilibrium conditions given the distortions associated with the staggered price setting it shows that the complete stabilization of the price level is optimal in the absence of initial price dispersion while optimal inflation targets respond to changes in the level of relative price distortion in the presence of initial price dispersion

monetary policy and exchange rate interactions in a small open economy the transmission mechanisms of monetary policy in a small open economy like norway are analysed through structural vars with special emphasis on the interdependence between monetary policy and exchange rate movements by imposing a long run neutrality restriction on the real exchange rate thereby allowing the interest rate and the exchange rate to react simultaneously to news i find considerable interdependence between monetary policy and the exchange rate in particular following a contractionary monetary policy shock the real exchange rate immediately appreciates after which it gradually depreciates back to the baseline the results are found to be consistent with findings from an event study

an estimated canadian dsge model with nominal and real rigidities this paper develops a dynamic stochastic general equilibrium dgse model for the canadian economy and evaluates the real effects of monetary policy shocks to generate high and persistent real effects the model combines nominal frictions in the form of costly price adjustment with real rigidities modelled as convex costs of adjusting capital and employment

inflation inertia and the optimal hybrid inflation price level target a hybrid inflation price level target combines elements of both inflation and price level targets the paper derives an optimal hybrid target within a new keynesian model with inflation persistence due to price indexation the result generalizes a result by vestin forthcoming that the optimal policy could be implemented with a price level targeting regime we show that the optimal price level drift in the hybrid target is equal to the degree of price indexation if there is complete indexation the optimal monetary regime is inflation targeting

testing monetary policy intentions in open economies 1 introductionthis article examines the relationship between economic openness and inflation performance among the most prominent research on this topic is the work by romer 1993 he demonstrates a negative relationship between economic openness and the inflation level his finding has also been viewed as supportive albeit indirectly of time consistency theory kydland and prescott 1977 1 romer 1993 argues that policymakers in more open economies have less incentive to adopt an expansionary monetary policy his argument is based on the assumption that monetary surprises in more open economies result in higher inflation for a given increase in output romer s finding that more open economies have lower inflation levels leads him to infer that this is evidence of time consistency in monetary policy practices however romer s work has not been generally accepted temple 2002 provides evidence that the openness inflation correlation does not stem from time consistency theory because the inflation level may not properly reveal the monetary authorities policy intentions temple questions this inference because it starts from a strong but unjustified assumption more open economies possess a relatively steeper phillips curve consequently temple proposes that the examination of the positive relationship between openness and the slope of the phillips curve is a fundamental condition for romer s argument he however finds little support for the positive relationship between economic openness and the slope of the phillips curve further work on the relationship of openness and monetary policy intentions comes from clarida gali and gertler 2001 2002 hereafter cgg in cgg 2001 the authors present a simple open economy model with a taylor type interest rate policy rule taylor 1993 the article concludes that the optimal monetary policy in an open economy has the same solution as that in a closed economy derived in cgg 1999 the authors also suggest that there is a direct link between the degree of economic openness and the aggressiveness of monetary policy they state that o penness does affect the parameters of the model suggesting a quantitative implication h ow aggressively a central bank should adjust the interest rate in response to inflationary pressures depends on the degree of openness cgg 2001 p 248 in subsequent work cgg 2002 revisit the issue based on a dynamic open economy new keynesian model and the role of monetary policy in open economies is refined consistent with the argument in cgg 2001 they find that the optimal monetary policy rule in an open economy is isomorphic to that in a closed economy in the nash equilibrium they also suggest that openness does not affect the optimality of a policy rule in such a scenario on the other hand economic openness does affect optimal monetary policy when the foreign optimal policy is endogenous in the domestic country s objective function this effect however is ambiguous in direction because the relationship between the degree of economic openness and the aggressiveness of monetary policy is determined by the relative size of trade and wealth effects of changes in foreign output this line of theoretical literature is limited and does not offer a definitive conclusion on the relationship between economic openness and monetary policy intentions our article provides an alternative empirical evaluation of the relationship based on prior literature we use inflation variability and persistence as the measures of monetary policy intentions one branch of the literature such as taylor 1999 cgg 2000 and owyang 2001 argues that aggressive monetary policy reduces the volatility of inflation for instance cgg 2000 estimate a forward looking taylor rule for the period between 1960 i and 1996 iv they use paul volcker s appointment as chairman of the federal reserve system as a regime shift to a more aggressive anti inflation policy stance

escaping from a liquidity trap and deflation the foolproof way and others existing proposals to escape from a liquidity trap and deflation including my foolproof way are discussed in the light of the optimal way to escape the optimal way involves three elements 1 an explicit central bank commitment to a higher future price level 2 a concrete action that demonstrates the central bank s commitment induces expectations of a higher future price level and jump starts the economy and 3 an exit strategy that specifies when and how to get back to normal a currency depreciation is a direct consequence of expectations of a higher future price level and hence an excellent indicator of those expectations furthermore an intentional currency depreciation and a crawling peg as in the foolproof way can implement the optimal way and in particular induce the desired expectations of a higher future price level i conclude that the foolproof way is likely to work well for japan which is in a liquidity trap now as well as for the euro area and the united states in case either would fall into a liquidity trap in the future

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

conflicts of interest information provision and competition in the financial services industry abstract in some markets sellers have better information than buyers over which products best serve a buyer s needs depending on the market structure this may lead to conflicts of interest in the provision of information by sellers this paper studies this issue in the market for financial services the analysis presents a new model of competition between banks where price competition influences the ensuing incentives for truthful information revelation we also compare conflicts of interest in two different firm structures specialized banking and one stop banking

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

monetary policy in a low pass through environment in a dynamic new keynesian optimizing model we introduce incomplete exchange rate pass through on import prices three results stand out first unlike canonical models with perfect pass through which emphasize a type of isomorphism incomplete pass through renders the analysis of monetary policy of an open economy fundamentally different from the one of a closed economy second productivity driven deviations from the law of one price assume the interpretation of endogenous cost push shocks third the optimal commitment policy relative to discretion entails a smoothing of the deviations from the law of one price and requires more stable nominal and real exchange rates

rethinking classical trade analyses within a framework of capitalist development a classical trade theory which comprises smith s productivity theory ricardo s reasoning against the corn laws torrens s argument for extended colonisation and mill s recommendation to send capital abroad is advanced it portrays england s economic expansion in the nineteenth century lacunae exist however because of these economists belief in the automatic spread of industries to the agricultural countries and their inattention to the economic advances made by the late coming capitalist countries as well as the impact of england s capital exports on the capital importing countries subsequent researches which address these and which relate to current debates on theories and policies are discussed 1996 academic press limited

the validity of the long run heckscher ohlin theorem in the ricardian system applying burgstaller s ricardian two sector growth model to the two country open economy this paper shows that the long run heckscher ohlin theorem holds also in a ricardian world in addition it is shown that if two ricardian countries that are different only in their demand parameters open trade comparative advantage and the corresponding trade pattern at trade opening continue in the long run after the opening of trade

on inflation and output with costly price changes a simple unifying result this paper determines the real effects of credible disinflation when price setting is staggered the results are surprising a fairly quick disinflation causes a boom this finding suggests that nominal price rigidity alone does not explain why disinflation is costly in actual economies this abstract was borrowed from another version of this item

following the leader the relevance of the fed funds rate for inflation targeting countries abstract in a new keynesian model for a small open economy we derive a cpi inflation based taylor rule that implements the flexible price allocation we conclude that in this rule the natural rate of interest should be linked to the foreign interest rate and to domestic productivity shocks this rule ensures that the cpi real rate moves in order to induce movements in consumption that are coherent with the flexible price allocation the empirical evidence shows that inflation targeting central banks respond to movements in the fed funds rate besides reacting to expected cpi inflation and to the domestic output gap this is true for developed and emerging economies furthermore we find that in emerging countries the response to foreign variables is not different from zero as suggested by theory when domestic inflation rather than cpi inflation is introduced in the policy rule

stabilisation policy rational expectations and price level versus inflation targeting a survey we survey literature comparing inflation targeting it and price level targeting pt as macroeconomic stabilisation policies our focus is on new keynesian models and areas that have seen significant developments since ambler s 2009 price level targeting and stabilisation policy a survey journal of economic surveys 23 5 974 997 survey optimal monetary policy the zero lower bound financial frictions and transition costs of adopting a pt regime ambler s conclusion that pt improves social welfare in new keynesian models is fairly robust but we note an interesting split in the literature pt consistently outperforms it in models where policymakers commit to simple taylor type rules but results in favour of pt when policymakers minimise loss functions are overturned with small deviations from the baseline model since the beneficial effects of pt appear to hang on the joint assumption that agents are rational and the economy new keynesian we discuss survey and experimental evidence on rational expectations and the applied macro literature on the empirical performance of new keynesian models overall the evidence is not clear cut but we note that new keynesian models can pass formal statistical tests against macro data and that models with rational expectations outperform those with behavioural expectations i e heuristics in direct statistical tests we therefore argue that policymakers should continue to pay attention to pt

factor proportions and ricardian comparative advantage thoughts on uchiyama in a ricardo pasinetti world inferring a long run comparative advantage from a stationary state factor proportions differential is invalid since the latter may be present in the absence of the former and will be a consequence not the cause of long run comparative advantage where such exists

investor overconfidence and the forward premium puzzle we offer an explanation for the forward premium puzzle in foreign exchange markets based upon investor overconfidence in the model overconfident individuals overreact to their information about future inflation which causes greater overshooting in the forward rate than in the spot rate thus when agents observe a signal of higher future inflation the consequent rise in the forward premium predicts a subsequent downward correction of the spot rate the model can explain the magnitude of the forward premium bias and several other stylized facts related to the joint behaviour of forward and spot exchange rates our approach is also consistent with the availability of profitable carry trade strategies

does trade openness matter for aggregate instability abstract this paper presents a cash in advance model of a small open economy and shows that whether an inflation targeting interest rate rule introduces aggregate instability depends in general on the degree of openness to international trade this result emerges regardless of whether prices are sticky or flexible in a closed economy as the monetary authority responds to movements in inflation the resulting changes in interest rates affect aggregate consumption through an intertemporal substitution effect and an inflation tax effect in a small open economy this policy also induces changes in the terms of trade which depending on the degree of openness can generate counteracting effects on consumption as a consequence the implications of interest rate rules on macroeconomic stability in an open economy differ from those in a closed economy

unifying ricardo s theories of growth and comparative advantage the paper formally integrates ricardo s two sector growth model with his theory of comparative advantage differences with conventional representations of ricardian trade theory as well as with heckscher ohlin samuelson theory are noted it is shown that the ricardian equilibrium terms of trade are fully determinate as against the standard millian view also trade may depending on direction of specialization inhibit rather than promote growth and lead to a net contraction of the world economy copyright 1986 by the review of economic studies limited
