can money matter for interest rate policy in this paper it is shown that money can matter for macroeconomic stability under interest rate policy when transactions frictions are non negligible we develop a sticky price model with a shopping time function which induces the marginal utility of consumption to depend on the predetermined stock of money held at the beginning of the period equilibrium stability and uniqueness are then ensured by a passive interest rate policy whereas activeness is associated with an explosive equilibrium by reacting to changes in beginning of period real balances the central bank can restore stability interest rates further depend on lagged real balances even if the central bank acts in an entirely forward looking way as under discretionary optimization if the model is revised such that end of period money provides transaction services money can in principle be neglected for a stabilizing interest rate policy discretionary monetary policy is however likely to be associated with equilibrium indeterminacy which can be avoided if interest rates are set contingent on beginning of period real balances

what asset prices should be targeted by a central bank this paper investigates the monetary policy design for restoring equilibrium determinacy our interests are whether a central bank should respond to asset price fluctuations and if so what asset prices should be targeted we show that a monetary policy response to the price of a productive tangible asset capital price is helpful for equilibrium determinacy while that to the price of an intangible asset that reflects a firm s profit share prices is a source of equilibrium indeterminacy this result comes from the two assets prices moving in opposite directions in response to a permanent increase in inflation

the quantitative analytics of the basic neomonetarist model this paper constructs a dynamic macroeconomic model with less than perfect price flexibility which has a classical side consistent with real business cycle theory augmented by investment adjustment costs increasing returns to scale and a new flexible formalization of imperfect competition something akin to the classical dichotomy is justified by a mode of approximation appropriate for a model in which one state variable adjusts quickly while another state variable adjusts slowly even with investment adjustment costs monetary expansions are found to raise the real interest rate the determinants of real rigidity and the macroeconomic rate of price adjustment are investigated copyright 1995 by ohio state university press

capital accumulation sectoral heterogeneity and the taylor principle abstract in the presence of capital accumulation the taylor principle may not be sufficient for determinacy under reasonable parameter values in this paper i consider a two sector extension of the models used in the existing literature i show that what matters for whether the taylor principle is sufficient is the price stickiness of investment goods price stickiness of consumer goods on the other hand matters very little the taylor principle is sufficient i find unless there is considerable price stickiness in the investment goods sector

monetary and fiscal policy interactions in a new keynesian model with capital accumulation and non ricardian consumers the paper examines simple monetary and fiscal policy rules consistent with determinate equilibrium dynamics in the absence of ricardian equivalence under this assumption government debt turns into a relevant state variable which needs to be accounted for in the analysis of equilibrium dynamics the key analytical finding is that without explicit reference to the level of government debt it is not possible to infer how strongly the monetary and fiscal instruments should be used to ensure determinate equilibrium dynamics specifically we identify bifurcations associated with threshold values of steady state debt leading to qualitative changes in the local determinacy requirements

new keynesian models durable goods and collateral constraints abstract econometric evidence suggests that in response to monetary policy shocks durable and non durable spending co move positively and durable spending exhibits a much larger sensitivity to the shocks a standard two sector new keynesian model with perfect financial markets is at odds with these facts the introduction of a borrowing constraint where durables play the role of collateral assets helps in reconciling the model with the empirical evidence

the taylor principle fights back part ii abstract the existing literature holds that the taylor principle often leads to indeterminacy in new keynesian models that allow for capital accumulation and limited asset market participation this conclusion is special however to the case of continuous full employment when the assumption of perfect wage flexibility is relaxed very slightly so that the labor market clears quickly but not instantaneously determinacy is the norm the threat of indeterminacy is limited to a tiny irrelevant corner of the parameter space where the elasticity of labor supply is unusually high and real wage adjustment is unbelievably fast everywhere else the taylor principle guarantees a unique rational expectations equilibrium the dramatic difference in results reflects the sensitivity of the monetary transmission mechanism to the speed of adjustment in the labor market

the collapse of purchasing power parities during the 1970 s one of the striking facts concerning the relationship beiveen prices and exchange rates during the 1970 s has been the dismal performance of the predictions of the simple versions of the purchasing power parity doctrine ppp that doctrine in its absolute version states that the equilibrium exchange rate between domestic and foreign currencies equals the ratio of domestic to foreign price levels the relative version of the doctrine relates equilibrium changes in exchange rates to changes in the ratio of domestic to foreign prices during the 1970 s short run changes in exchange rates bore little relationship to short run differentials in national inflation rates and frequently divergences from purchasing power parities have been cumulative this paper reviews and analyzes the empirical record of exchange rates and prices during the 1970 s and the analysis is based on the experience of the dollar pound the dollar frecch franc and the dollar dm exchange rates section 2 presents the evidence on ppp during the 1970 s and contrasts it with the evidence from the 1920 s a period during which the doctrine held up reasonably well this analysis is relevant for assessing whether the flexible exchange rate system was successful in providing national economies with an added degree of insulation from foreign shocks and whether it provided policymakers with an added instrument for the conduct of macroeconomic policy the evidence regarding devia tions from purchasing power parities is also relevant for determining whether there is a case for managed float section 3 attempts to explain what went wrong with

nominal price rigidity money supply endogeneity and business cycles abstract this paper investigates the ability of nominal price rigidity to explain the co movement of inflation with the cyclical component of output observed in the post war u s data a dynamic general equilibrium model is constructed with the introduction of monopolistic competition and nominal price rigidity in a standard real business cycle model allowing for an endogenous money supply rule it is then demonstrated that sticky price models can explain the observed associations between movements in inflation and output much better than flexible price models this result depends little on whether money supply is assumed to be endogenous or not

the effects of electricity reforms on productivity and efficiency of china s fossil fired power plants an empirical analysis abstract this paper investigates the effects of electricity reforms on productivity and efficiency of china s generation plants based on the third industrial census data and the first economic census data partial factor productivity pfp analysis indicates that the productivity improvements in labor and capital inputs associated with the reforms are approximately 26 and 45 respectively the effect of the reforms on fuel expense is weakly significant but there is evidence of significant productivity improvement in fuel usage further total factor productivity tfp analysis shows that the efficiency gain from the reforms is still significant when the substitution effect of labor and capital inputs are considered though the magnitude is much lower than that of the pfp analysis the effect of the reforms on technical efficiency becomes weakly significant when fuel expense is further included in tfp analysis but a significant positive effect is expected if fuel input is measured in physical quantity

interest rate policy debt and indeterminacy with distortionary taxation abstract the interest rate setting policy of the central bank influences the amount of funds the government must raise to pay the interest on its existing debt with distortionary taxation fiscal adjustments feed back on the model s endogenous variables the conditions under which interest rate and tax policies are compatible with a uniquely determined stable equilibrium are derived for an optimizing sticky price model if the fiscal government continuously balances its budget active interest rate policy easily leads to indeterminacy if there is a positive steady state stock of public debt when short run deficits are allowed active interest rate policy and determinacy are compatible unless the tax rate is too strongly increasing in response to changes in debt the real interest rate or output

the development trajectories of wind power and solar pv power in china a comparison and policy recommendations wind power and solar pv power are the two major renewable energy technologies that are currently under rapid development in china in this paper the similarities and differences between the development trajectories of the two sectors are examined in terms of development status development policy and development trend five interesting findings from the comparison are obtained and several policy recommendations are made this paper contributes to the study on china s renewable energy policy from a new perspective

why inflation targeting central banks seem to follow a standard taylor rule abstract central banks only caring about inflation stability seem to follow a standard taylor rule the alleged reaction to the output gap could be a reaction of the nominal interest rate to variations in the natural real rate of interest

measuring international competitiveness experience from east asia this paper uses a new measure of real exchange rates as an indicator of international competitiveness this new measure involves defining all prices and exchange rates on an appropriately weighted basket of currencies rather than a single currency the measure is applied to the data for japan korea thailand malaysia and singapore for comparison purposes we calculate real exchange rates based on purchasing power parity ppp for these countries to check for the relative performance of the two measures cointegration tests are employed the results indicate that the new measure tends to be closely related with the export growth for the sample countries while the ppp based measure is not moreover the ppp based real exchange rates tend to understate the measures of competitiveness for these countries this result has important implications in terms of the levels of these countries exchange rates as well as the well known balassa hypothesis

a review of pumped hydro energy storage development in significant international electricity markets the global effort to decarbonise electricity systems has led to widespread deployments of variable renewable energy generation technologies which in turn has boosted research and development interest in bulk electrical energy storage ees however despite large increases in research funding many electricity markets with increasingly large proportions of variable renewable generation have seen little actual bulk ees deployment while this can be partly attributed to the need for technological developments it is also due to the challenge of fairly rewarding storage operators for the range of services that storage provides to the wider network especially in markets that have undergone significant restructuring and liberalisation pumped hydroelectric energy storage phes is the overwhelmingly established bulk ees technology with a global installed capacity around 130 gw and has been an integral part of many markets since the 1960s this review provides an historical overview of the development of phes in several significant electrical markets and compares a number of mechanisms that can reward phes in different international market frameworks as well as providing up to date information about phes a primary motivation for this work is to provide an overview about the types of rewards available to bulk ees for the wider storage community including investors technology developers and policy makers observing that bulk ees projects seem to be unattractive investments for the private sector the paper also includes a brief discussion in terms of public sector investment

commercial policy the terms of trade and the real exchange rate revisited abstract we estimate the effects of commercial policy and changes in the external terms of trade on the real exchange rate for four latin american economies using data on internal relative prices we find that the greater the elasticity of the non traded price level with respect to the price of importables the larger is the real exchange rate effect of import restrictions but the smaller is the real exchange rate effect of changes in the external terms of trade

house prices borrowing constraints and monetary policy in the business cycle i develop a general equilibrium model with sticky prices credit constraints nominal loans and asset prices changes in asset prices modify agents borrowing capacity through collateral value changes in nominal prices affect real repayments through debt deflation monetary policy shocks move asset and nominal prices in the same direction and are amplified and propagated over time the financial accelerator is not constant across shocks nominal debt stabilises supply shocks making the economy less volatile when the central bank controls the interest rate i discuss the role of equity debt indexation and household and firm leverage in the propagation mechanism finally i find that monetary policy should not target asset prices as a means of reducing output and inflation volatility

the perils of taylor rules abstract since john taylor s 1993 carnegie rochester conf ser publ policy39 195 214 seminal paper a large literature has argued that active interest rate feedback rules that is rules that respond to increases in inflation with a more than one for one increase in the nominal interest rate are stabilizing in this paper we argue that once the zero bound on nominal interest rates is taken into account active interest rate feedback rules can easily lead to unexpected consequences specifically we show that even if the steady state at which monetary policy is active is locally the unique equilibrium typically there exist an infinite number of equilibrium trajectories originating arbitrarily close to that steady state that converge to a liquidity trap that is a steady state in which the nominal interest rate is near zero and inflation is possibly negative journal of economic literature classification numbers e52 e31 e63

financial factors and monetary policy determinacy and learnability of equilibrium abstract we contribute to the debate on whether central banks should respond to financial factors in monetary policy rules by evaluating equilibrium determinacy and e stability in the presence of a financial accelerator policies responding to lagged asset prices either reduce the region of determinacy or e stability in the parameter space however a response to current asset prices expands both regions of determinacy and e stability policy rules reacting to credit volume constrict the determinacy region most policies responding to credit spreads expand determinacy and e stability regions we favor the inclusion of current asset prices or credit spreads in monetary policy rules

limited asset markets participation monetary policy and inverted aggregate demand logic abstract this paper incorporates limited asset markets participation in dynamic general equilibrium and develops a simple analytical framework for monetary policy analysis aggregate dynamics and stability properties of an otherwise standard business cycle model depend nonlinearly on the degree of asset market participation while moderate participation rates strengthen the role of monetary policy low enough participation causes an inversion of results dictated by conventional wisdom the slope of the is curve changes sign the taylor principle is inverted optimal welfare maximizing discretionary monetary policy requires a passive policy rule and the effects and propagation of shocks are changed however a targeting rule implementing optimal policy under commitment delivers equilibrium determinacy regardless of the degree of asset market participation our results may justify fed s behavior during the great inflation period

interest rate rules and transitional dynamics in an endogenously growing open economy abstract this paper sets up an endogenous growth model of an open economy in which the monetary authority implements a gradualist interest rate rule with targets for both inflation and economic growth we show that under a passive rule a monetary equilibrium exists and is unique moreover the equilibrium is locally determinate by contrast an active rule implies either two equilibria one high growth and one low growth or none in the case of two equilibria the high growth equilibrium is locally determinate while the low growth equilibrium is a source besides the stabilization and growth effects of alternative target policies are also explored in this study moreover in departing from the existing literature we turn to focus on the analysis of transition with a particular emphasis on the case of imperfect credibility

a dynamic new keynesian life cycle model societal aging demographics and monetary policy in this paper we first construct a dynamic new keynesian model that incorporates life cycle behavior a la gertler 1999 in order to study whether structural shocks to the economy have asymmetric effects on heterogeneous agents namely workers and retirees we also examine whether considerations of life cycle and demographic structure alter the dynamic properties of the monetary business cycle model specifically the degree of amplification in impulse responses according to our simulation results shocks indeed have asymmetric impacts on different households and the demographic structure does alter the size of responses against shocks by changing the degree of the trade off between substitution and income effects

the political economy of electricity dispatch reform in china the transition to a cleaner and more cost efficient electricity system in china is political economic as well as technological an example is the reform of china s method of dispatching power plants which potentially affects the economic relationships between consumers and producers between grid and generating companies and between central and provincial governments historically coal fired power plants in china all received roughly the same number of operating hours regardless of efficiency or cost in 2007 chinese government agencies began to pilot energy efficient dispatch which requires that generators be dispatched on the basis of thermal efficiency using a case study of guangxi zhuang autonomous region in southern china we evaluated potential energy and cost savings from a change to energy efficient dispatch we found that the savings are at best relatively small because large efficient generators already account for a significant share of total generation moreover as an administrative policy that does not change economic incentives energy efficient dispatch exacerbates imbalances and center provincial tensions in the current system we argue that incentive based dispatch reform is likely to produce better outcomes and that the keys to this reform are empowering an independent regulator with pricing authority and establishing a formal transparent ratemaking process

state dependent pricing and the general equilibrium dynamics of money and output economists have long suggested that nominal product prices are changed infrequently because of fixed costs in such a setting optimal price adjustment should depend on the state of the economy yet while widely discussed statedependent pricing has proved difficult to incorporate into macroeconomic models this paper develops a new tractable theoretical state dependent pricing framework we use it to study how optimal pricing depends on the persistence of monetary shocks the elasticities of labor supply and goods demand and the interest sensitivity of money demand

investment and monetary policy learning and determinacy of equilibrium we explore determinacy and expectational stability learnability of rational expectations equilibrium ree in new keynesian nk models that include capital using a consistent calibration across three different models labor only firm specific capital or an economy wide rental market for capital we provide a clear picture of when ree is determinate and learnable and when it is not under a variety of monetary policy rules our findings make a case for greater optimism concerning the use of such rules in nk models with capital while bullard and mitra s 2002 2007 findings for the labor only nk model do not always extend to models with capital we show that determinate and learnable ree can be achieved in nk models with capital if there is i plausible capital adjustment costs ii some weight given to output in the policy rule and or iii a policy of interest rate smoothing

modeling unit commitment in political context case of china s partially restructured electricity sector restructuring an electricity sector entails a complex realignment of political and economic institutions which may both delay and distort the achievement of satisfactorily competitive conditions in research and planning for policy interventions in power systems under these varied regulatory environments typical operational models may neglect important interactions between techno economic criteria and political constraints leading to poor understanding of underlying causes of inefficiency and to inappropriate recommendations we develop tractable formulations of the unit commitment problem based on integer clustering of similar units that endogenize important political factors in the northeast grid region of china we demonstrate the importance of these interactions on operations and provide a set of options for researchers to explore further pathways for china s ongoing power system reforms for example wind integration a key policy priority is inhibited by the interaction of institutions limiting short and long term sources of flexibilities in interprovincial trade

chinese resource demand and the natural resource supplier this article provides empirical evidence on the effects of chinese resource demand on the resource rich natural resource supplier using the example of australia a structural var model is used to examine the effects of chinese resource demand commodity prices and foreign output on the macroeconomy with a formally specified mining and resource export sector the key findings of the article are that shocks to chinese demand and commodity prices result in a sustained increase in commodity prices and mining investment and a positive impact on the resource sector however these shocks eventually lead to lower real domestic output with factors of production moving out of the nonresource sectors and into the resource sector resulting in a fall in nonresource sector output which is not fully offset by the rise in resource sector output the results also indicate some market power by the natural resource supplier

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

chaotic interest rate rules a growing empirical and theoretical literature argues in favor of specifying monetary policy in the form of taylor type interest rate feedback rules that is rules whereby the nominal interest rate is set as an increasing function of inflation with a slope greater than one around an intended inflation target this paper shows that such rules can easily lead to chaotic dynamics the result is obtained for feedback rules that depend on contemporaneous or expected future inflation the existence of chaotic dynamics is established analytically and numerically in the context of calibrated economies the battery of fiscal policies that has recently been advocated for avoiding global indeterminacy induced by taylor type interest rate rules such as liquidity traps are shown to be unlikely to provide a remedy for the complex dynamics characterized in this paper

the response of exchange rates to permanent and transitory shocks under floating exchange rates abstract using the joint behavior of inflation and real exchange rates we develop an empirical model to uncover the sources of the fluctuations in the real dollar exchange rates of four major industrial countries under the current float this model allows us to construct two time series for each country pair one representing the permanent component of each real exchange rate and the other the purely transitory component over the period as a whole transitory shocks played a relatively small but statistically significant role real dollar exchange rates therefore did not simply evolve in response to permanent shocks instead there are instances in which temporary shocks made a substantial contribution we conclude that the random walk model though an approximate statistical description of real exchange rate behavior is a poor guide to model structure jel f31

equilibrium indeterminacy and asset price fluctuation in japan a bayesian investigation this paper investigates sources of asset price fluctuation in japan using an estimated financial accelerator model for explicit treatment of expectational beliefs characterized by sunspots the model is analyzed over the parameter space where the equilibrium can be indeterminate we show that indeterminacy arises if the financial accelerator effect is sufficiently large according to our bayesian estimation results japan s economy was affected by sunspot shocks however the contribution of the sunspots to asset price volatility was low rather net worth and cost shocks drove the asset price fluctuation we find however that the sunspots substantially affected capital investment

market segmentation and wind curtailment an empirical analysis abstract china s wind power has experienced explosive growth and reshaped the overall energy mix since 2009 however increasing investment in the wind power industry has been accompanied by persistent and serious wind curtailment since 2010 leading to significant efficiency loss this paper argues that the interprovincial market segmentation which is driven by political motivations is a key factor contributing to wind curtailment we first construct an interprovincial electricity market segmentation index this is then used as an independent variable to explain the variation in wind curtailment rates a panel dataset of 28 provinces during the 2009 2016 period is used for empirical analysis the results clearly show that market barriers positively contribute to wind power curtailment specifically a 10 decrease in the market segmentation index will lead to a 4 3 5 3 decrease in wind power curtailment

real balance effects timing and equilibrium determination this paper examines whether the existence and the timing of real balance effects contribute to the determination of the absolute price level as suggested by patinkin 1949 1965 and if they afiect conditions for local equilibrium uniqueness and stability i show that there exists a unique price level sequence that is consistent with an equilibrium under interest rate policy only if beginning ofperiod money yields transaction services predetermined real money balances can then serve as a state variable implying that interest rate setting must be passive a violation of the taylor principle for unique stable and non oscillatory equilibrium sequences on the contrary when the end of period money stock facilitates transactions the equilibrium displays nominal indeterminacy and equilibrium uniqueness requires an interest rate setting consistent with the taylor principle

the design of monetary and fiscal policy a global perspective abstract we study the emergence of multiple equilibria in models with capital and bonds under various monetary and fiscal policies we show that the presence of capital is indeed another independent source of local and global multiplicities even under active policies that yield local determinacy we also show how a very similar mechanism generates multiplicities in models with bonds and distortionary taxation we then explore the design of monetary policies that avoid multiple equilibria we show that interest rate policies that respond to the output gap while potentially a source of significant inefficiencies may be effective in preventing multiple equilibria and costly oscillatory equilibrium dynamics

price indexation habit formation and the generalized taylor principle abstract we prove that the generalized taylor principle under which the nominal interest rate reacts more than one for one to a change in inflation in the long run is a necessary and under some extra mild restrictions on parameters sufficient condition for determinacy in a sticky price model with interest rate smoothing in monetary policy partial dynamic price indexation and habit formation in consumption

equity ownership in international joint ventures the impact of source country factors this study examines the impact of four source country factors on the equity ownership in international joint ventures ijvs these factors are exchange rate cost of borrowing export capability and management orientation based on a sample of 8 078 ijvs in china this study shows that equity ownership tends to be higher for parent firms from a source country with strong currency low cost of borrowing strong export capability and high uncertainty avoidance

optimal monetary policy with capital and a financial accelerator abstract whether there is a trade off between price and financial stability is an open question this paper characterises optimal monetary policy analytically in a new keynesian economy with capital and a financial accelerator in addition to stabilising inflation there is an incentive to smooth volatility in the net worth of borrowers and this presents a trade off for monetary policy this trade off can be eliminated if policymakers can additionally choose an optimal transfer to borrowers enriching the model with fire sales and countercyclical bankruptcy costs there is also an incentive to smooth volatility in default and the capital stock an optimal transfer to borrowers is not sufficient to eliminate the trade off in that case with fewer instruments than targets optimal transfers are state contingent and countercyclical while monetary policy stabilises inflation

equilibria under monetary and fiscal policy interactions in a portfolio choice model abstract this paper studies how the presence of income taxes changes the properties of general equilibrium models with monetary and fiscal policy interactions it is found that from a global perspective the only policy regime that leads to a unique equilibrium is one where fiscal policy is active i e the fiscal theory of the price level regime in sims 1994 from a local perspective there are three regimes in particular and relative to the previous literature following leeper 1991 a new third regime exists where a passive fiscal rule combined with a passive monetary rule can still deliver determinacy where the same area of the parameter space would lead to multiple solutions if taxes were lump sum to obtain the size of the new regime the paper characterizes analytically the extent to which tax cuts are self financing and how the distortionary tax laffer curve looks near the steady state in the new regime monetary and fiscal backstops are brought into play so as to rule out off equilibrium dynamics and inflation can temporarily increase in order to increase seigniorage revenues with this flexibility the monetary policy is consistent with the real debt remaining bounded and the arithmetic that follows is monetarist and unpleasant in the sense of sargent and wallace 1981

on exchange rates nominal and real abstract the paper first develops an australian commodity currency exchange rate model which is extended to deal with real exchange rates as well the nominal and real exchange rate versions are then tested on swiss data for the post bretton woods period while the model tracks the swiss franc nominal exchange rate vis a vis the dollar and the major european currencies very well swiss ppp real exchange rates are found to be heavily contaminated with measurement error as that error explains the large co movements in nominal and ppp real exchange rates those co movements are largely irrelevant to the ppp debate

foreign aid economic structure and dependence abstract an inflow of foreign capital leads to structural changes in the economy by lowering the relative price of tradable to non tradable goods it induces a decline of the relative share of tradables in the country s production the effect on consumption shares is less obvious since price and income effects may tend to be offsetting the existence of foreign aid also establishes a dependence of the economy on the outside world estimates of the degree of such dependence through the use of national accounts aggregates would be biased by the afore mentioned effect on relative prices hence specifically estimates of time tends based on the use of current prices may lead to different conclusions from those which employ constant prices for comparison the inferences of this paper are derived in a simple two sector small country model the concreteness and probable relevance of the main propositions are then demonstrated by empirical illustrations

learning about monetary policy rules when the housing market matters abstract in this paper we study a general equilibrium model with a housing market and use stability under adaptive learning as a criterion to evaluate monetary policy rules an important feature of the model is that there exist credit constrained borrowers who use their housing assets as collateral to finance purchases we evaluate both conventional taylor rules and rules that incorporate other targets such as housing prices we find that the effect of responding to housing prices in addition to output and inflation depends critically on the assumed information structure of the economy

do credit market imperfections justify a central bank s response to asset price fluctuations do credit market imperfections justify a central bank s response to asset price fluctuations this study addresses this question from the perspective of equilibrium determinacy in the model we use prices are sticky and the working capital of firms is subject to asset values because of a lack of commitment if credit market imperfections exist to a small degree the taylor principle is a necessary and sufficient condition for equilibrium determinacy and monetary policy response to asset price fluctuations is good from the perspective of equilibrium determinacy however if credit market imperfections exist to a large degree such that the collateral constraint is binding then the taylor principle no longer guarantees equilibrium determinacy and monetary policy response to asset price fluctuations becomes a source of equilibrium indeterminacy we find that the existence of credit market imperfections makes it unsuitable to initiate a monetary policy response to deal with asset price fluctuations we also find that reductions in credit market imperfections can enlarge the indeterminacy region of the model parameters

is forward looking inflation targeting destabilizing the role of policy s response to current output under endogenous investment we show that with endogenous investment virtually all monetary policy rules that set a nominal interest rate in response solely to expected future inflation induce real indeterminacy in models with i staggered prices ii staggered prices and staggered wages and iii staggered prices staggered wages and firm specific capital in i policy s response to current output can help significantly in ensuring determinacy with an infinite labor supply elasticity but little with empirically plausible labor supply elasticity in ii responding to output always helps a great deal though under low price stickiness and without capital adjustment cost it may call for a moderate response to output in order to ensure determinacy for a wide range of response to inflation in iii even a tiny response to output can always render equilibrium determinate for a wide range of response to inflation

new perspectives on capital sticky prices and the taylor principle abstract our main result is that dynamic new keynesian dnk models with firm specific capital feature a substantial amount of endogenous price stickiness we use this insight to assess the desirability of alternative interest rate rules and make the case for combining active monetary policy with interest rate smoothing and or some responsiveness of the nominal interest rate to real economic activity the key mechanism behind our results is also useful from a positive point of view the feature of firm specific capital increases the empirical appealingness of dnk models as documented by a growing body of literature

interactions between renewable energy policy and renewable energy industrial policy a critical analysis of china s policy approach to renewable energies this paper analyzes china s policy approach to renewable energies and assesses how effectively china has met the ideal of appropriate interactions between renewable energy policy and renewable energy industrial policy first we briefly discuss the interactions between these two policies then we outline china s key renewable energy and renewable industrial policies and find that china s government has well recognized the need for this policy interaction after that we study the achievements and problems in china s wind and solar pv sector during 2005 2012 and argue that china s policy approach to renewable energies has placed priority first on developing a renewable energy manufacturing industry and only second on renewable energy itself and it has not effectively met the ideal of appropriate interactions between renewable energy policy and renewable energy industrial policy lastly we make an in depth analysis of the three ideas underlying this policy approach that is the green development idea the low carbon leadership idea and indigenous innovation idea we conclude that chinas policy approach to renewable energies needs to enhance the interactions between renewable energy policy and renewable energy industrial policy the paper contributes to a deeper understanding of china s policy strategy toward renewable energies

investment and interest rate policy abstract the paper s theorems reverse two standard results of new keynesian economics simply by appending endogenous investment to a benchmark imperfect competition sticky price model our results are a a passive interest rate rule where the monetary authority responds to inflation by lowering the real interest rate implies local equilibrium uniqueness whereas an active rule does not generate a locally unique equilibrium b a temporary exogenous increase in the nominal interest rate causes a temporary increase in output and investment extensions of the benchmark model including generalized preferences and alternative interest rate rules are also examined journal of economic literature classification numbers e12 e31 e52

the taylor principle in a medium scale macroeconomic model abstract we consider a medium scale new keynesian model which combines features that have been shown to explain fairly well postwar u s business cycles our main result demonstrates that the determinacy properties of forward looking interest rate rules resemble at least qualitatively the corresponding outcomes under current looking rules we explain how and why the empiri cally relevant features of our model generate this novel result

taylor rules in a model that satisfies the natural rate hypothesis the authors analyze the restrictions necessary to ensure that the interest rate policy rule used by the central bank does not introduce real indeterminacy into the economy they conduct this analysis in a flexible price economy and a sticky price model that satisfies the natural rate hypothesis a necessary and sufficient condition for real determinacy in the sticky price model is that there must be nominal and real determinacy in the corresponding flexible price model this arises if and only if the taylor rule responds aggressively to lagged inflation rates

back to the future rethinking auctions for renewable electricity support abstract the effectiveness and cost effectiveness of two main types of instruments feed in tariffs and quotas with tradable green certificates have usually been compared in the literature on renewable electricity promotion due to negative past experiences with a third instrument auctions this instrument has been broadly dismissed in academics and until recently also in policy practice however and based on an in depth review of experiences with auction schemes for renewable electricity around the world this paper argues that some of the problems with auctions in the past can be mitigated with the appropriate design elements and that indeed auctions can play an important role in the future implementation of renewable electricity support instruments around the world the paper provides a proposal for the coherent integration of several design elements

regulatory design for res e support mechanisms learning curves market structure and burden sharing drawing from relevant experiences in power systems around the world this paper offers a review of existing policy support mechanisms for res e with a detailed analysis of their regulatory implications while recent studies provide an account of current res e support systems in this paper we focus on some of the impacts these mechanisms have on the overall energy market structure and its performance given the rising importance of res e in systems everywhere these impacts should no longer be overlooked

the reform of electricity power sector in the pr of china deregulation was launched as a concept in the united states more than a decade ago the european union commission has also formally announced that electric deregulation must be completed by the end of 2005 deregulation or reform has already been a popular topic on the electricity power sector this paper will discuss the restructuring and regulatory reforms in the pr china s power sector it begins with a discussion of the characteristics of electricity reform or deregulation in other countries including the us the united kingdom and so on it will be followed by the industry structure and regulatory framework that characterized china s power industry during the latter part of the 20th century and the history of china s reform to restructure the power industry to competitive suppliers of generating services in recent years it discusses the role of the state power corporation in the reform and gives a detailed description of the latest electricity reform in the year 2002 the paper concludes with some thoughts regarding future challenges and trends on the reform for china s power sector

testing for indeterminacy an application to u s monetary policy reply this paper considers a prototypical new keynesian model in which the equilibrium is undetermined if monetary policy is passive the likelihood based estimation of dynamic equilibrium models is extended to allow for indeterminacies and sunspot fluctuations we construct posterior weights for the determinacy and indeterminacy region of the parameter space and estimates for the propagation of fundamental and sunspot shocks according to the estimated model u s monetary policy post 1982 is consistent with determinacy whereas the pre volcker policy is not we find that before 1979 indeterminacy substantially altered the propagation of shocks

investment interest rate policy and equilibrium stability abstract carlstrom and fuerst 2005 investment and interest rate policy a discrete time analysis journal of economic theory 123 4 20 show that in the presence of investment activity and price stickiness indeterminacy of equilibrium is induced by forward looking monetary policy that sets the interest rate in response only to future inflation in a stochastic version of their model we find that this indeterminacy problem is due to a cost channel of monetary policy whereby inflation expectations become self fulfilling and the problem can be overcome once the forward looking policy responds also to current output or contains sufficiently strong interest rate smoothing since this prevents the self fulfilling expectations we also show that when e stability is adopted as the selection criterion from multiple equilibria even the forward looking policy generates a locally unique non explosive e stable fundamental rational expectations equilibrium as long as the policy response to expected future inflation is sufficiently strong

market driven coal prices and state administered electricity prices in china this paper analyzes how the chinese government adjusts electricity prices for both industrial and residential users in response to changes in coal prices using an asymmetric error correction model our results show that there is a long term relation between the coal price and electricity prices but the relationship is weak especially for residential pricing in the short run we find electricity prices are adjusting faster upwards than downwards price adjustment towards long run equilibrium is faster for residential users upwards than downwards on the other hand we find no evidence of asymmetric equilibrium adjustment in the electricity price for industrial use the weak long term relationship reflects the rigidity in electricity pricing and government s reluctance to subject end users to fluctuations of raw materials cost shifts

on the mechanics of new keynesian models abstract the monetary transmission mechanism in new keynesian models is put to scrutiny we show that contrary to the conventional view the transmission mechanism does not operate through the real interest rate channel instead equilibrium inflation is approximately determined as in a flexible price model output is then pinned down by the new keynesian phillips curve the real rate only reflects the feasibility to keep consumption smooth when income changes contractionary monetary policy shocks reducing output and inflation are consistent with an increase decline or no change in the real rate consistency with the real rate channel is observational not structural

bounded interest rate feedback rules in continuous time this paper analyzes the dynamic consequences of interest rate feedback rules in a flexible price model where money enters the utility function two alternative rules are considered based on past or predicted inflation rates the main feature is to consider inflation rates that are selected over a bounded time horizon we prove that if the central bank s forecast horizon is not too long an active and forward looking monetary policy is not destabilizing the equilibrium trajectory is unique and monotonic this is an advantage with respect to active and backward looking policies that are shown to lead to a unique but fluctuating dynamic

fiscal adjustment and inflation targeting in less developed countries inflation targeting may not be viable in less developed countries ldcs where policymakers rely too heavily on cuts in infrastructure investment to balance the budget using a mix of analytical and numerical methods we demonstrate that the equilibrium ceases to be saddle point stable under active policy when infrastructure cuts account for 30 70 of fiscal adjustment and the return on infrastructure exceeds a comparatively low threshold value the result is robust to the form of the taylor rule the degree of real wage flexibility the initial level of debt the choice of a balanced budget or debt targeting rule and the q elasticity of private investment spending

demand side management in china the context of china s power industry reform abstract the reform of china s power industry has lasted for decades while the implementation of demand side management dsm in china is still in its infancy in this paper we present a comprehensive study of the dsm and demand response dr programs in china under the context of china s power industry reform we first present a brief introduction of the background including the socio economic status and geographical location of china the energy policy of china china s power industry the smart grids and microgrid in china and the reform of china s power industry then based on the introduction of dsm and the analysis of dsm practices in some countries we discuss the development status of dsm and the reform of electricity pricing in china finally the main challenges in five aspects for the future development of dsm programs in china are proposed and discussed these challenges include customer understanding and participation advanced metering infrastructure ami and information and communication technology ict pricing mechanisms and optimal scheduling big data analytics based decision support as well as government regulations and market policies

investment and interest rate policy a discrete time analysis this paper analyzes the restrictions necessary to ensure that the interest rate policy rule used by the central bank does not introduce local real indeterminacy into the economy it conducts the analysis in a calvo style sticky price model a key innovation is to add investment spending to the analysis in this environment local real indeterminacy is much more likely in particular all forward looking interest rate rules are subject to real indeterminacy

macroeconomic in stability under real interest rate targeting we show that in a one sector monetary endogenous growth model under real interest rate targeting the local stability properties of the economy s balanced growth path depend crucially on the exact formulation of the cash in advance constraint and the degree of productive externalities in particular when a positive fraction including 100 of gross investment is subject to the liquidity constraint the model exhibits indeterminacy and sunspots if and only if the equilibrium wage hours locus is positively sloped and steeper than the labor supply curve on the other hand when real money balances are required only for the household s consumption purchases the economy always displays saddle path stability and equilibrium uniqueness regardless of the strength of productive externalities

the price of gold and the exchange rate abstract this paper examines the theoretical relationship between the major exchange rates and the prices of internationally traded commodities in the empirical section the case of gold is analyzed using forecast error data among other things it is found that since the dissolution of the bretton woods international monetary system floating exchange rates among the major currencies have been a major source of price instability in the world gold market and as the world gold market is dominated by the european currency bloc appreciations or depreciations of european currencies have strong effects on the price of gold in other currencies

optimal interest rate rules asset prices and credit frictions we study optimal taylor type interest rate rules in an economy with credit market imperfections our analysis builds on the agency cost framework of carlstrom and fuerst 1997 agency costs net worth and business fluctuations a computable general equilibrium analysis american economic review 87 893 910 which we extend in two directions first we embed monopolistic competition and sticky prices second we modify the stochastic structure of the model in order to generate a countercyclical premium on external finance this is achieved by linking the mean distribution of investment opportunities faced by entrepreneurs to aggregate total factor productivity we model monetary policy in terms of simple welfare maximizing interest rate rules we find that monetary policy should respond to increases in asset prices by lowering interest rates however when monetary policy responds strongly to inflation the marginal welfare gain of responding to asset prices vanishes within the class of linear interest rate rules that we analyze a strong anti inflationary stance always attains the highest level of welfare

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

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

backward looking interest rate rules interest rate smoothing and macroeconomic instability the existing literature on the stabilizing properties of interest rate feedback rules has stressed the perils of linking interest rates to forecasts of future inflation such rules have been found to give rise to aggregate fluctuations due to self fulfilling expectations in response to this concern a growing literature has focused on the stabilizing properties of interest rate rules whereby the central bank responds to a measure of past inflation the consensus view that has emerged is that backward looking rules contribute to protecting the economy from embarking on expectations driven fluctuations a common characteristic of the existing studies that arrive at this conclusion is their focus on local analysis the contribution of this paper is to conduct a more global analysis we find that backward looking interest rate feedback rules do not guarantee uniqueness of equilibrium we present examples in which for plausible parameterizations attracting equilibrium cycles exist the paper also contributes to the quest for policy rules that guarantee macroeconomic stability globally our analysis indicates that policy rules whereby the interest rate is set as a function of the past interest rate and current inflation are likely to ensure global stability provided that the coecient on lagged interest rates is greater than unity

inflation illusion and the taylor principle an experimental study we develop a simple experimental setting to evaluate the role of the taylor principle which holds that the nominal interest rate has to respond more than one for one to fluctuations in the inflation rate to exert a stabilizing effect in our setting the average inflation rate fluctuates around the inflation target if the computerized central bank obeys the taylor principle if the taylor principle is violated the average inflation rate persistently deviates from the target these deviations from the target are less pronounced if inflation rates cannot be as readily observed as nominal interest rates this result is consistent with the interpretation that subjects underestimate the influence of inflation on the real return to savings if the inflation rate is only observed ex post

real exchange rate behavior the recent float from the perspective of the past two centuries using annual data spanning two centuries for dollar sterling and franc sterling real exchange rates we find strong evidence of mean reverting real exchange rate behavior using simple stationary autoregressive models estimated on prefloat data we easily outperform nonstationary real exchange rate models in dynamic forecasting exercises over the recent float such stationary univariate equations explain 60 80 percent of the in sample variation in real exchange rates although the degree of short run persistence may be high the econometric estimates imply a half life of shocks to the real exchange rate of about 6 years for dollar sterling and a little under 3 years for franc sterling

on grid electricity tariffs in china development reform and prospects abstract with the introduction of market oriented measures in china s power sector in the mid 1980s electricity sale prices to the grid companies on grid electricity tariffs became the focus of the energy industry thus affecting all related stakeholders including fuel suppliers power generators and end use consumers a number of changes have gradually been undertaken in terms of electricity tariff settings and their implementation to address specific requirements of the expansion of the power industry at each stage of its development on grid electricity tariffs had been used as a key lever to attract investment in power generation at an early stage of reform and then to encourage competition in the power industry in response to the rising concerns about environmental protection and the promotion of clean energy utilisation tariffs have progressively been developed for renewable electricity generation which has contributed to massive expansion of the renewable power industry in china this paper reviews key milestones of the development of on grid electricity tariffs in china examines the tariff setting mechanisms of coal fired power plants and renewable power generation analyses the factors associated with the adjustments of the tariff levels and discusses the options for further reform and more effective electricity pricing

optimal simple and implementable monetary and fiscal rules welfare maximizing monetary and fiscal policy rules are studied in a model with sticky prices money and distortionary taxation the ramsey optimal policy is used as a point of comparison the main findings are the size of the inflation coefficient in the interest rate rule plays a minor role for welfare it matters only insofar as it affects the determinacy of equilibrium optimal monetary policy features a muted response to output interest rate rules that feature a positive response to output can lead to significant welfare losses the welfare gains from interest rate smoothing are negligible optimal fiscal policy is passive the optimal monetary and fiscal rule combination attains virtually the same level of welfare as the ramsey optimal policy

should central banks respond to movements in asset prices in recent decades asset booms and busts have been important factors in macroeconomic fluctuations in both industrial and developing countries in light of this experience how if at all should central bankers respond to asset price volatility we have addressed this issue in previous work bernanke and gertler 1999 the context of our earlier study was the relatively new but increasingly popular monetary policy framework known as inflation targeting see e g bernanke and frederic mishkin 1997 in an inflation targeting framework publicly announced medium term inflation targets provide a nominal anchor for monetary policy while allowing the central bank some flexibility to help stabilize the real economy in the short run the inflation targeting approach gives a specific answer to the question of how central bankers should respond to asset prices changes in asset prices should affect monetary policy only to the extent that they affect the central bank s forecast of inflation to a first approximation once the predictive content of asset prices for inflation has been accounted for there should be no additional response of monetary policy to assetprice fluctuations in use now for about a decade inflationtargeting has generally performed well in practice however so far this approach has not often been stress tested by large swings in asset prices our earlier research employed simulations of a small calibrated macroeconomic model to examine how an inflation targeting policy defined as one in which the central bank s instrument interest rate responds primarily to changes in expected inflation might fare in the face of a boom and bust cycle in asset prices we found that an aggressive inflationtargeting policy rule in our simulations one in which the coefficient relating the instrument interest rate to expected inflation is 2 0 substantially stabilizes both output and inflation in scenarios in which a bubble in stock prices develops and then collapses as well as in scenarios in which technology shocks drive stock prices intuitively inflation targeting central banks automatically accommodate productivity gains that lift stock prices while offsetting purely speculative increases or decreases in stock values whose primary effects are through aggregate demand conditional on a strong policy response to expected inflation we found little if any additional gains from allowing an independent response of central bank policy to the level of asset prices in our view there are good reasons outside of our formal model to worry about attempts by central banks to influence asset prices including the fact that as history has shown the effects of such attempts on market psychology are dangerously unpredictable hence we concluded that inflationtargeting central banks need not respond to asset prices except insofar as they affect the inflation forecast in the spirit of recent work on robust control the exercises in our earlier paper analyzed the performance of policy rules in worst case discussants robert shiller yale university glenn rudebusch federal reserve bank of san francisco kenneth rogoff harvard university

sticky price and limited participation models of money a comparison abstract we provide new evidence that models of the monetary transmission mechanism should be consistent with at least the following facts after a contractionary monetary policy shock the aggregate price level responds very little aggregate output falls interest rates initially rise real wages decline by a modest amount and profits fall we compare the ability of sticky price and limited participation models with frictionless labor markets to account for these facts the key failing of the sticky price model lies in its counterfactual implications for profits the limited participation model can account for all the above facts but only if one is willing to assume a high labor supply elasticity 2 percent and a high markup 40 percent the shortcomings of both models reflect the absence of labor market frictions such as wage contracts or factor hoarding which dampen movements in the marginal cost of production after a monetary policy shock 1997 elsevier science b v

real exchange rates under the gold standard purchasing power parity is one of the most important equilibrium conditions in international macroeconomics empirically it is also one of the most hotly contested numerous recent studies for example have sought to determine the validity of purchasing power parity using data from the post bretton woods float and have reached different conclusions we assert that most such studies are flawed for two reasons first the post 1973 data contain by definition only a very limited amount of the low frequency information relevant for examination of long run parity second the dynamic econometric techniques used to model deviations from parity are typically quite crude with respect to admissible low frequency dynamics both deficiencies are rectified in the present paper with dramatic results we construct a new data set of 16 real exchange rates covering more than a century of the classic gold standard period and we study deviations from parity using long memory models that allow for subtle forms of mean

capital and macroeconomic instability in a discrete time model with forward looking interest rate rules abstract we establish the necessary and sufficient conditions for local real determinacy in a discrete time production economy with monopolistic competition and a quadratic price adjustment cost under forward looking policy rules for the case where capital is in exogenously fixed supply and the case with endogenous capital accumulation using these conditions we show that i indeterminacy is more likely to occur with a greater share of payment to capital in value added production cost ii indeterminacy can be more or less likely to occur with constant capital than with variable capital iii indeterminacy is more likely to occur when prices are modelled as jump variables than as predetermined variables iv indeterminacy is less likely to occur with a greater degree of steady state monopolistic distortions and v indeterminacy is less likely to occur with a greater degree of price stickiness or with a higher steady state inflation rate in contrast to some existing research our analysis indicates that capital tends to lead to macroeconomic instability by affecting firms pricing behavior in product markets rather than households arbitrage activity in asset markets even under forward looking policy rules

introduction to monetary policy and capital accumulation the papers in this symposium address the issue of multiple equilibria that can be induced by monetary policy in models with capital accumulation in particular they examine how the taylor principle under which interest rates respond more than proportionately to increases in inflation can generate multiple equilibria they also explore the design of policies to avoid the problem of multiple equilibria and indeterminacy

introducing the emissions trading system to china s electricity sector challenges and opportunities we examine the challenges and opportunities to introduce emissions trading ets in china s electricity sector in which the interaction between ets and electricity market reform plays a major role china s electricity sector is currently in a slow progress towards a more competitive and market based system both equal share dispatching policy and regulated wholesale and retail pricing policies pose significant challenges for implementation of ets in china s electricity sector one of the important points of ets is to give a price for carbon emissions and establish a cost pass through mechanism reminded that the essential of carbon pricing is to put a price on carbon emissions that is equal to discounted value of the external damages it should be regarded as a part of broader policy package for energy and resources price reform this will require that any low carbon power policy should be considered as a part of whole policy package aiming at further liberalizing the electricity sector in china three policy options are identified to incorporate ets with electricity reform under different circumstances a combination of those three options is also proposed to break the lock and reinforce the positive interaction between ets and the transition towards a competitive electricity system in link with current pilot ets designs a roadmap to introduce ets in a stepwise manner is suggested
