bond market exposures to macroeconomic and monetary policy risks i provide empirical evidence of changes in the u s treasury yield curve and related macroeconomic factors and investigate whether the changes are brought about by external shocks monetary policy or by both to explore this i characterize bond market exposures to macroeconomic and monetary policy risks using an equilibrium term structure model with recursive preferences in which inflation dynamics are endogenously determined in my model the key risks that affect bond market prices are changes in the correlation between growth and inflation and changes in the conduct of monetary policy using a novel estimation technique i find that the changes in monetary policy affect the level of bond yields through their effect on expected inflation while the changes in the correlation between growth and inflation affect both the level as well as the volatility of bond yields consequently the changes in the correlation structure are the main contributor to bond risk premia and to bond market volatility the time variations within a regime and risks associated with moving across regimes lead to the failure of the expectations hypothesis and to the excess bond return predictability regression of cochrane and piazzesi 2005 as in the data

multiple solution indeterminacies in monetary policy analysis abstract a sizeable fraction of recent research on monetary policy has been concerned with issues relating to analytical indeterminacies i e multiple solutions in rational expectations re models most of the literature features sophisticated re analysis conducted within dynamic models that reflect optimizing behavior by individual agents and incorporate taylor style policy rules a few papers have suggested that some of the particular indeterminacy arguments are misleading or irrelevant for the most part however there has been little dissent from the position that these indeterminacies present a genuine problem for monetary policy makers the purpose of the present paper by contrast is to argue that conclusions based on multiple solution indeterminacy findings are of dubious merit rather generally

on identification of bayesian dsge models this article is concerned with local identification of individual parameters of dynamic stochastic general equilibrium dsge models estimated by bayesian methods identification is often judged by a comparison of the posterior distribution of a parameter with its prior however these can differ even when the parameter is not identified instead we propose two bayesian indicators of identification the first follows a suggestion by poirier of comparing the posterior density of the parameter of interest with the posterior expectation of its prior conditional on the remaining parameters the second examines the rate at which the posterior precision of the parameter gets updated with the sample size using data simulated at the parameter point of interest for an increasing sequence of sample sizes t for identified parameters the posterior precision increases at rate t for parameters that are either unidentified or are weakly identified the posterior precision may get updated but its rate of update wi

the fiscal theory of the price level in a world of low interest rates abstract a central equation for the fiscal theory of the price level ftpl is the government budget constraint or government valuation equation which equates the real value of government debt to the present value of fiscal surpluses in the past decade the governments of most developed economies have paid very low interest rates and there are many other periods in the past in which this has been the case in this paper we revisit the implications of the ftpl in a world where the rate of return on government debt may be below the growth rate of the economy considering different sources for the low returns dynamic inefficiency the liquidity premium of government debt or its favorable risk profile this article is part of a special issue entitled fiscal and monetary policies

are interest rate regressions evidence for a taylor rule abstract in a variety of recent papers researchers have found that interest rate behaviour approximately follows a taylor rule we show that such interest rate behaviour results when the central bank may be following quite different monetary policy rules from the one proposed by taylor in other words an interest rate relation with output and inflation does not identify a central bank reaction function

asset price momentum and monetary policy time varying parameter estimation of taylor rules abstractin this article we consider two new independent variables as inputs to the taylor rule these are the equity and housing momentum variables and are introduced to investigate the potential usefulness of these two variables in guiding the fed to lean against potential bubbles such effectiveness cannot adequately be evaluated if the taylor rule estimation follows the standard regression methodology that has been criticized in the literature to be econometrically incorrect using a time varying parameter estimation methodology we find that equity momentum as an input in the taylor rule does not contribute to changes in fed funds however the housing momentum plays an important role econometrically and can be a useful tool in setting fed funds rates

sophisticated monetary policies in standard monetary policy approaches interest rate rules often produce indeterminacy a sophisticated policy approach does not sophisticated policies depend on the history of private actions government policies and exogenous events and can differ on and off the equilibrium path they can uniquely implement any desired competitive equilibrium when interest rates are used along the equilibrium path implementation requires regime switching these results are robust to imperfect information our results imply that the taylor principle is neither necessary nor sufficient for unique implementation they also provide a direction for empirical work on monetary policy rules and determinacy

marginal loss modeling in lmp calculation this paper discusses the pricing of marginal transmission network losses in the locational marginal pricing approach recently deployed in the iso new england iso ne standard market design smd project implemented by alstom s t d energy automation and information eai business the traditional loss model is studied and a new model is proposed the new model achieves more defendable and predictable market clearing results by introducing loss distribution factors to explicitly balance the consumed losses in the lossless dc power system model the distributed market slack reference is also introduced and discussed the lmp components produced by the two models are studied and compared under changes in slack reference numerical examples are presented to further compare the two models

empirical evidence on inflation expectations in the new keynesian phillips curve abstract we review the main identification strategies and empirical evidence on the role of expectations in the new keynesian phillips curve paying particular attention to the issue of weak identi

announcements of interest rate forecasts do policymakers stick to them if central banks value the ex post accuracy of their forecasts previously announced interest rate paths might affect the current policy rate we explore whether this forecast adherence has influenced the monetary policies of the reserve bank of new zealand and the norges bank the two central banks with the longest history of publishing interest rate paths we derive and estimate a policy rule for a central bank that is reluctant to deviate from its forecasts the rule can nest a variety of interest rate rules we find that policymakers appear to be constrained by their most recently announced forecasts

monetary policy indeterminacy and identification failures in the u s results from a robust test we propose a novel identi cation robust test for the null hypothesis that an estimated new keynesian model has a reduced form consistent with the unique stable solution against the alternative of sunspot driven multiple equilibria our strategy is designed to handle identi cation failures as well as the misspeci cation of the relevant propagation mechanisms we invert a likelihood ratio test for the cross equation restrictions cer that the newkeynesian system places on its reduced form solution under determinacy if the cer are not rejected sunspot driven expectations can be ruled out from the model equilibrium and we accept the structural model otherwise we move to a second step and invert an anderson and rubin type test for the orthogonality restrictions or implied by the system of euler equations the hypothesis of indeterminacy is accepted if the or are not rejected we investigate the nite sample performance of the suggested two steps testing strategy by some monte carlo experiments we apply our robust test to a new keynesian ad as model estimated with actual u s post wwii data in spite of some evidence of weak identi cation

making weak instrument sets stronger factor based estimation of inflation dynamics and a monetary policy rule the problem of weak identification has recently attracted attention in the analysis of structural macroeconomic models using robust methods can result in large confidence sets making precise inference difficult we overcome this problem in the analysis of the hybrid new keynesian phillips curve and a forward looking taylor rule by employing stronger instruments we suggest exploiting information from a large macroeconomic data set by generating factors and using them as additional instruments this approach results in stronger instrument sets and hence smaller weak identification robust confidence sets it allows us to conclude that there has been a shift toward more active monetary policy from the pre volcker regime to the volcker greenspan tenure

monetary policy with interest on reserves abstract i analyze monetary policy with interest on reserves and a large balance sheet i show that conventional theories do not determine inflation in this regime so i base the analysis on the fiscal theory of the price level i find that monetary policy can peg the nominal rate and determine expected inflation with sticky prices monetary policy can also affect real interest rates and output though higher interest rates raise output and then inflation the conventional sign requires a coordinated fiscal monetary policy contraction i show how conventional new keynesian models also imply strong monetary fiscal policy coordination to obtain the usual signs i address theoretical controversies a concluding section places our current regime in a broader historical context and opines on how optimal fiscal and monetary policy will evolve in the new regime

determinacy and identification with taylor rules the new keynesian taylor rule theory of inflation determination relies on explosive dynamics by raising interest rates in response to inflation the fed induces ever larger inflation unless inflation jumps to one particular value on each date however economics does not rule out explosive inflation so inflation remains indeterminate attempts to fix this problem assume that the government will choose to blow up the economy if alternative equilibria emerge by following policies we usually consider impossible the taylor rule is not identified without unrealistic assumptions thus taylor rule regressions do not show that the fed moved from passive to active policy in 1980

lack of confidence the zero lower bound and the virtue of fiscal rules abstract in the presence of the zero lower bound standard business cycle models with a taylor type monetary policy rule are prone to equilibrium multiplicity a drop in private sector confidence can drive the economy into a liquidity trap without any change in fundamentals i show in the context of a standard new keynesian model that it is possible to design ricardian fiscal spending rules that insulate the economy from such expectations driven liquidity traps in the case of price adjustment costs desirable fiscal rules ensure that a drop in confidence does not lead to a decline in real marginal costs in the case of nominal wage adjustment costs desirable fiscal spending rules ensure that a drop in confidence does not lead to a decline in the ratio of the marginal rate of substitution between private consumption and hours worked relative to the real wage rate

when preferences for a stable interest rate become self defeating monetary policymakers often seem to have preferences for a stable interest rate in addition to stable inflation and output in this paper we investigate the implications of having an interest rate level term in the loss function when the policymaker lacks commitment technology we show that such preferences may become self defeating in the sense that they generate a less stable interest rate than in the case without preferences for interest rate stability

equilibrium selection observability and backward stable solutions abstract the robustness of stability under learning to observability of exogenous shocks is examined regardless of observability assumptions the minimal state variable solution is robustly stable under learning provided the expectational feedback is not both positive and large while the nonfundamental solution is never robustly stable overlapping generations and new keynesian models are considered and concerns raised in cochrane 2011 2017 are addressed

social ties and international entrepreneurship opportunities and constraints affecting firm internationalization international entrepreneurship involves the identification and exploitation of opportunities for international exchange yet little is known about the entrepreneurial methods used for opportunity recognition while previous work emphasizes effects operating at the level of the business network i propose that the recognition of exchange opportunities is a highly subjective process shaped by entrepreneurs existing ties with others based on interview data collected from 41 managers i develop a comprehensive measure for classifying different methods of opportunity recognition i then use this measure to classify 665 international exchange ventures set up by entrepreneurs in four chinese cities in contrast with past research i find virtually no role for blind luck although the majority of exchange opportunities were discovered rather than sought these discoveries were intentional rather than accidental i also find that entrepreneurs idiosyncratic connections with others both promote and inhibit international exchange tie based opportunities lead to higher quality and more valuable exchanges that are constrained in terms of geographic psychic and linguistic distance from this i conclude that entrepreneurial networks have distinct opportunity horizons that limit the reach of tie based exchanges and potentially lead to sub optimal internationalization trajectories

experience with pjm market operation system design and implementation this paper outlines the fundamental features of the pjm day ahead energy market and real time energy market the day ahead market is based on a voluntary least cost security constrained unit commitment and dispatch with several fundamental design features that ensure the market is robust and competitive this market offers market participants the option to lock in energy and transportation charges at binding day ahead prices the flexibility of the day ahead market rules provide all participants with equal access to the day ahead market through consistent price signals and by providing all participants with the ability to submit virtual demand bids and virtual supply offers these mechanisms promote liquidity in the markets economic incentives drive the convergence of the day ahead and real time market prices the real time energy market is based on security constrained economic dispatch and is cleared based on the actual system operating conditions the lmp based markets support reliable grid operations through efficient price signals

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

when does a central bank s balance sheet require fiscal support abstract using a simple general equilibrium model we argue that it would be appropriate for a central bank with a large balance sheet composed of long duration nominal assets to have access to and be willing to ask for support for its balance sheet by the fiscal authority otherwise its ability to control inflation may be at risk this need for balance sheet support a within government transaction is distinct from the need for fiscal backing of inflation policy that arises even in models where the central bank s balance sheet is merged with that of the rest of the government

monetary policy bond risk premia and the economy within an affine model of the term structure of interest rates where bond yields get driven by observable and unobservable macroeconomic factors parameter restrictions help identify the effects of monetary policy and other structural disturbances on output inflation and interest rates and decompose movements in long term rates into terms attributable to changing expected future short rates versus risk premia when estimated the model highlights a broad range of channels through which monetary policy affects risk premia and the economy risk premia affect monetary policy and the economy and the economy affects monetary policy and risk premia

improving an unjustified common practice in ex post lmp calculation a common practice for the ex post lmp calculation at a number of u s isos uses a small constant range typically from 2 0 to 0 1 mw as each generator s lower and upper bounds this paper shows that this is an unjustified practice as the marginal units and lmp may change if the bounds are changed a simple yet effective improvement is proposed

the new keynesian liquidity trap abstract many new keynesian models produce a deep recession with deflation at the zero bound these models also make unusual policy predictions useless government spending technical regress capital destruction and forward guidance can raise output moreover these predictions are larger as prices become less sticky and as changes are expected further in the future i show that these predictions are strongly affected by equilibrium selection for the same interest rate path equilibria that bound initial jumps predict mild inflation small output variation negative multipliers small effects of far off expectations and a smooth frictionless limit fiscal policy considerations suggest the latter equilibria

forward guidance communication commitment or both abstract forward guidance has been suggested as a form of commitment odyssean by the policymaker or as a way of conveying information delphic i analyze the interaction between households and the central bank as a game in which the central bank sends messages without private information the set of equilibrium payoffs is independent of any announcements pure odyssean forward guidance is redundant with private information communication can have social value forward guidance is well suited to leverage preexisting credibility to communicate a central bank s private information about its own preferences or beliefs

deliverable robust ramping products in real time markets the increasing penetration of variable energy resources has led to more uncertainties in power systems flexible ramping products frp have been adopted by several electricity markets to manage the uncertainties we reveal that neglected line congestion for frp may not only cause infeasibility but also result in a failure of cost recovery to address the deliverability issues on frp this paper proposes a new concept deliverable robust ramping products drrp in real time markets the drrp includes generation ramping reserve and generation capacity reserve the drrp is deliverable and immunized against any predefined uncertainty it also fully addresses the bid cost recovery issue caused by the line congestion in existing frps the prices of drrp are derived within the affine adjustable robust optimization aaro framework these prices can be used to identify valuable reserves among available reserves and quantify the values of flexible resources that provide reserves this paper also proposes a general approach to obtaining the time decoupled prices for drrp and generation which can be used for the market settlement of the first interval only in real time markets simulations on a 3 bus system and the ieee 118 bus system are performed to illustrate the concept of drrp and the advantages of drrp compared to existing frp

identification robust analysis of dsge and structural macroeconomic models abstract full and limited information identification robust methods are proposed for structural systems notably dsge models which are valid whether identification is weak or strong theory intrinsic or data specific the proposed methods are applied to a standard new keynesian system for the u s single and multi equation estimation and fit are also compared when a unique rational expectation stable equilibrium is imposed the model is rejected in contrast limited information inference produces informative results regarding forward looking behavior in the nkpc and precise conclusions on feedback coefficients in the reaction function which cannot be reached via single equation methods

fiscal policy and liquidity traps with heterogeneous agents this paper explores global dynamics in a monetary model with limited asset market participation and the zero lower bound on nominal interest rates it is shown that a rise in government transfers to non ricardian consumers financed by debt based taxes to ricardian consumers is capable of escaping disinflationary paths typically convergent to a liquidity trap fiscal policy does not need to be unsustainable at the low inflation steady state to avoid liquidity traps as argued in the context of the standard single representative agent setup

linguistic distance as a determinant of bilateral trade we introduce a measure of language difficulty called linguistic distance into a modified gravity model to determine whether a language being further away from english affects the level of trade our sample of 36 non english speaking countries includes japan and south korea which we argue are special cases because of world war ii the korean war and subsequent close political and economic ties with the united states presence of a stock of immigrants in the home country has been shown to enhance trade with the country of origin controlling for immigrant network and information attributes the special relationship with japan and korea and the standard gravity model variables we find that trade will be less between the united states and a country the further that country s language is from english these results hold for aggregate exports and imports and for exports and imports of consumer and producer manufactures

stepping on a rake the fiscal theory of monetary policy abstract the fiscal theory of the price level can describe monetary policy governments can set interest rate targets and thereby affect inflation with no change in fiscal surpluses the same basic mechanism describes interest rate targets forward guidance open market operations and quantitative easing it does not require any monetary pricing or other frictions in the presence of long term debt higher interest rates lead to temporarily lower inflation a challenging sign i derive and replicate the results of the sims 2011 stepping on a rake model which first produced this negative sign and produces realistic impulse response functions i show that sims result is robust to many model features but essentially requires long term debt

uncertainty marginal price transmission reserve and day ahead market clearing with robust unit commitment the increasing penetration of renewable energy in recent years has led to more uncertainties in power systems these uncertainties have to be accommodated by flexible resources i e upward and downward generation reserves in this paper a novel concept uncertainty marginal price ump is proposed to price both the uncertainty and generation reserve at the same time the energy is priced at locational marginal price lmp a novel market clearing mechanism is proposed to credit the generation and reserve and to charge the load and uncertainty within the robust unit commitment in the day ahead market we derive the umps and lmps in the robust optimization framework ump helps allocate the cost of generation reserves to uncertainty sources we prove that the proposed market clearing mechanism leads to partial market equilibrium we find that transmission reserves must be kept explicitly in addition to generation reserves for uncertainty accommodation we prove that transmission reserves for ramping delivery may lead to financial transmission right ftr underfunding in existing markets the ftr underfunding can be covered by congestion fund collected from uncertainty payment in the proposed market clearing mechanism simulations on a six bus system and the ieee 118 bus system are performed to illustrate the new concepts and the market clearing mechanism

immigrant links to the home country empirical implications for u s bilateral trade flows immigrants ties to their home countries can play a key role in fostering bilateral trade linkages immigrant ties include knowledge of home country markets language preferences and business contacts that have the potential to decrease trading transaction costs empirical results for the united states suggest that immigrant links have historically been important in increasing bilateral trade flows with immigrants home countries copyright 1994 by mit press

the international entrepreneurial dynamics of accelerated internationalisation the initial stages of internationalisation prior to firms having established their definitive sources of advantage remain the relatively unexplored area of the international business ib literature at these early stages where firms are seeking to establish themselves and new multinational firms are appearing to exploit new opportunities created by globalisation the entrepreneurial aspects of internationalisation come to the fore in this paper we aim to delineate an emerging field of ib scholarship we use the appearance of international new ventures and the phenomenon of accelerated internationalisation that they feature to identify a set of issues that has slipped through the net of some of the existing ib frameworks we propose that the salient features of accelerated and early internationalisation by the newly internationalising firm are best captured in a framework that is found at the intersection of entrepreneurial and internationalisation perspectives which we propose be known as international entrepreneurial dynamics we discuss such a framework in terms of entry points and pathways mapped by firms as they probe the ib arena and the key factors that impinge on behaviour and strategic choices in line with recent developments in the entrepreneurship literature these are grouped into three milestones of entrepreneurial processes that extend across national boundaries 1 the discovery of new opportunities 2 the deployment of resources in the exploitation of these opportunities and 3 the engagement with competitors implications for mne and internationalisation theory are discussed

ruling out divergent speculative bubbles abstract the growth in the empirical literature on testing for divergent in mean speculative bubbles indicates that existing theoretical arguments for ruling out such price paths are not sufficiently compelling here we strengthen the case for ruling out explosive or implosive bubbles a priori by filling in two gaps first we demonstrate why divergent stochastic bubbles arising from purely extrinsic uncertainty as in blanchard 1979 cannot be equilibria in a monetary optimizing model second we show why existing arguments for ruling out implosive price bubbles are insufficient in some cases and we provide stronger arguments

ex post pricing in the co optimized energy and reserve market this paper discusses an alternative to the ex post pricing model currently under development within iso new england s iso ne ancillary service market since iso ne s real time ancillary service market co optimizes both energy and reserve products ex post pricing is needed for both energy and reserve a co optimization approach for ex post pricing requires defining complex pricing rules and implementing heuristics to ensure consistent binding constraints with the ex ante dispatch in order to avoid complexity and uncertainty of required heuristics a new ex post pricing schema is proposed to calculate the ex post energy and reserve prices in a decoupled way while recognizing the coupling effect of energy and reserve in the proposed approach ex post energy prices are first computed by incorporating the ex ante marginal opportunity cost of reserve in the energy offer the ex post reserve prices are then calculated by considering the ex post marginal opportunity cost of energy this approach simplifies the implementation of ex post pricing rules in the iso ne market numerical examples are presented to further demonstrate the validity of this approach

money as stock abstract the fiscal theory determines the price level from the value of nominal government debt as a claim to government primary surpluses just as private stock is valued as a claim to corporate profits valuation equations are not constraints so this theory does not mistreat the government s intertemporal budget constraint i anchor the analysis in a simple cash in advance model when money demand falls to zero i show that the price level can still be determined by the government debt valuation equation

price level determinacy with an interest rate policy rule and rational expectations abstract this paper reconsiders a result obtained by sargent and wallace namely that price level indeterminacy obtains in their model if the monetary authorities adopt a feedback rule for the interest rate rather than the money stock it is shown that the indeterminacy vanishes if the interest rate rule is chosen so as to have a desired effect on the expected quantity of money demanded this holds even if considerable weight is given in the choice of a rule to the aim of smoothing interest rate fluctuations

monetary policy and the transaction role of money in the us the declining importance of money in transactions can explain the well known fact that u s interest rate policy was passive in the pre volcker period and active after 1982 we generalise a standard cashless new keynesian model woodford2003 by incorporating an explicit transaction role for money in the pre volcker period we estimate that money did play an important role and determinacy required a passive interest rate policy however after 1982 money no longer played an important role in facilitating transactions correspondingly the conventional view prevails and an active policy ensured equilibrium determinacy

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

frequentist evaluation of small dsge models this article proposes a new evaluation approach for the class of small scale hybrid new keynesian dynamic stochastic general equilibrium nk dsge models typically used in monetary policy and business cycle analysis the empirical assessment of the nk dsge model is based on a conditional sequence of likelihood based tests conducted in a vector autoregressive var system in which both the low and high frequency implications of the model are addressed in a coherent framework if the low frequency behavior of the original time series of the model can be approximated by nonstationary processes stationarity must be imposed by removing the stochastic trends this gives rise to a set of recoverable unit roots cointegration restrictions in addition to the short run cross equation restrictions the procedure is based on the sequence lr1 lr2 lr3 where lr1 is the cointegration rank test lr2 is the cointegration matrix test and lr3 is the cross equation restrictions test lr2 is computed conditional on lr

money as meta rule buchanan s constitutional economics as a foundation for monetary stability this paper explores james buchanan s contributions to monetary economics and argues these contributions form the foundation of a robust monetary economics paradigm while often not recognized for his contributions to monetary economics buchanan s scholarship offers important insights for current debates especially the renewed interest in narrow banking in the wake of the financial crisis we argue that the post 2007 crisis milieu creates a unique opportunity to recognize as buchanan did the vital role that money plays in the market as the grammar of commerce that recognition makes the need for more fundamental reform of our monetary regimes at the constitutional level more apparent making buchanan s work on monetary constitutions more relevant than ever before we then discuss how adopting buchanan s monetary framework can improve both monetary scholarship and institutions

risk based locational marginal pricing and congestion management this paper develops a new electricity market clearing mechanism called risk based locational marginal pricing rlmp the rlmp is derived from the risk based security constrained economic dispatch model where risk is modeled to capture the system s overall security level compared to the traditional locational marginal pricing lmp which is composed of three components energy congestion and loss the rlmp consists of an additional risk component the risk component is a price signal to reflect the system s overall security level this paper discusses the features of rlmp and analyzes its benefits over traditional lmps the proposed concept and method are illustrated on a six bus system and the wecc 240 bus system

heterogeneous expectations optimal monetary policy and the merit of policy inertia the design and analysis of optimal monetary policy is usually guided by the paradigm of homogeneous rational expectations instead we examine the dynamic consequences of design and implementation strategies when the actual economy features expectational heterogeneity agents have either rational or adaptive expectations consequently the central bank s ability to achieve price stability under heterogeneous expectations depends on its objective and implementation strategy an expectations based reaction function which appropriately conditions on private sector expectations performs exceptionally well however once the objective introduces policy inertia popular strategies have similar determinacy properties but they are less operational this finding calls for new implementation strategies under interest rate stabilization

fiscal policy in an expectations driven liquidity trap we study the effects of fiscal policy interventions in a liquidity trap in a model with nominal rigidities and an interest rate rule in a liquidity trap caused by a self fulfilling state of low confidence higher government spending has deflationary effects that reduce the spending multiplier when the zero lower bound is binding instead cuts in marginal labor tax rates are inflationary and become more expansionary when the zero lower bound is binding these findings contradict popular views about the effects of fiscal policy in a liquidity trap

do real balance effects invalidate the taylor principle in closed and open economies this paper examines the determinacy implications of forecast based monetary policy rules that set the interest rate in response to expected future inflation in a neo wicksellian model that incorporates real balance effects we show that the presence of such effects in closed economies restricts the ability of the taylor principle to prevent indeterminacy of the rational expectations equilibrium the problem is exacerbated in open economies particularly if the policy rule reacts to consumer price rather than domestic price inflation however determinacy can be restored in both closed and open economies with the addition of monetary policy inertia

are low interest rates deflationary a paradox of perfect foresight analysis we argue that an influential neo fisherian analysis of the effects of low interest rates depends on using perfect foresight equilibrium analysis under circumstances where it is not plausible for people to hold expectations of that kind we propose an explicit cognitive process by which agents may form their expectations of future endogenous variables perfect foresight is justified by our analysis as a reasonable approximation in some cases but in the case of a commitment to maintain a low nominal interest rate for a long time our reflective equilibrium implies neither neo fisherian conclusions nor implausibly strong predicted effects of forward guidance

adaptation and performance in foreign markets evidence of systematic under adaptation past empirical studies have yielded no consistent relationship between strategy adaptation and firm performance these inconclusive results may be partially due to a bias amongt managers to under adapt their host market strategies this paper presents the results of the second stage of a longitudinal study identifying a potential status quo bias among exporters leading to systematic under adaptation

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

determining optimal monetary speed limits abstract the proposal by walsh 2003 that policy should include a speed limit by having the change in the output gap as an additional term in a taylor type rule is shown to be exactly optimal given an appropriate parameterization

network linkages and location choice in foreign direct investment this paper shows that network linkage is an important determinant of location choice in foreign direct investment fdi network linkages are divided into internal intra firm and external inter firm linkages external linkages are further separated into strategic and relational linkages we found that taiwanese firms are keen on making external linkages but are indifferent to or incapable of making internal linkages through fdi strategic linkages motivate taiwanese fdi in the united states while relational linkages facilitate taiwanese fdi in southeast asia and china small firms are more sensitive to relational linkages than large firms in their choice of fdi location

social ties and partner identification in sino hong kong international joint ventures partner identification is an important and under studied precursor to selection and eventual performance of international joint ventures ijvs the mechanics of the identification process were investigated in depth across a sample of eighteen sino hong kong ijvs using the case study research method the cross case findings of this exploratory investigation support the idea that social networks provide a valuable resource for reducing ijv partner search costs specifically the findings reveal that while weakly linked bridge ties are valuable in identifying potential partners searches based on strong ties tend to be shorter and provide a more robust basis for inter partner cooperation

the robustness and efficiency of monetary policy rules as guidelines for interest rate setting by the european central bank abstract this paper examines the implications of recent research on monetary policy rules for practical monetary policy making with special emphasis on strategies for setting interest rates by the european central bank ecb the paper draws on recent research and new simulations of a large open economy model to assess the efficiency of a simple benchmark rule in comparison with other proposed rules further it stresses new results on the robustness of monetary policy rules in which each rule that is optimal or good according to one model or researcher is tested for robustness by other researchers using different models because of the large increase in the number of economists focussing on econometric evaluation of monetary policy rules for the interest rate instrument and because of the parallel increase in the variety of models being developed for this purpose much more evidence is becoming available on the robustness of simple monetary policy rules for the interest rate than ever before

ruling out unstable equilibria in new keynesian models the taylor rule is an incomplete description of monetary policy within a new keynesian model the nk model should be formulated with a money demand function and also embody a terminal condition on inflation explicitly designed to stop bubbles

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

the power of sunspots an experimental analysis abstract in an experiment using a coordination game with extrinsic random signals sunspots we systematically vary the stochastic process generating these signals and measure how signals affect behavior we find that sunspot equilibria emerge naturally with salient public signals however highly correlated private signals can also lead to sunspot driven behavior even when this is not an equilibrium private signals reduce the power of public signals as sunspot variables the higher the correlation of extrinsic signals and the more easily they can be aggregated the more powerful these signals are in distracting actions from the action that minimizes strategic uncertainty

can learnability save new keynesian models abstract mccallum 2009 argues that learnability can save new keynesian models from indeterminacies he claims the unique bounded equilibrium is learnable and the explosive equilibria are not however he assumes that agents can directly observe the monetary policy shock reversing this assumption i find the opposite the bounded equilibrium is not learnable and the unbounded equilibria are learnable more generally i argue that a threat by the fed to move to an unlearnable equilibrium for all but one value of inflation is a poor foundation for choosing the bounded equilibrium of a new keynesian model

heterogeneous expectations in monetary dsge models this paper derives a general new keynesian framework with heterogeneous expectations by explicitly solving the micro foundations underpinning the model the resulting reduced form is analytically tractable and encompasses the representative rational agent benchmark as a special case we specify a setup in which some agents as a result of cognitive limitations make mistakes when forecasting future macroeconomic variables and update their beliefs as new information becomes available while other agents have rational expectations we then address determinacy issues related to the use of different interest rate rules and derive policy implications for a monetary authority aiming at stabilizing the economy in a dynamic feedback system in which macroeconomic variables and heterogeneous expectations co evolve over time

quantitative easing is not as unconventional as it seems policy interest rates do not have to be short the means by which monetary authorities influence prices and quantities can differ but the obstacles to altering one rather than the other are not insuperable inflation is sluggish and expectations of future interest rates long and short nominal and real are diverse and uncertain these factors determine the limited power that monetary authorities enjoy when they conduct quantitative easing but this policy is not as unconventional as some have claimed and indeed can be viewed as broadly similar to conventional monetary measures the impact of quantitative easing however could be very different depending on the underlying structure of the economy and the fiscal authorities responses finally we note some important caveats that must be borne in mind when trying to evaluate the impact of quantitative easing particularly given the fact that the world s main financial markets are closely linked copyright 2012 oxford university press

convergence of volatile power markets with price based demand response price based demand response dr program is a mechanism for encouraging electricity consumers to dynamically manage their energy consumptions in response to time varying electricity prices and thereby reduce peak electricity demands and alleviate the pressure to power systems however it brings additional dynamics and new challenges to the real time supply and demand balance specifically if real time price based dr programs are widely deployed in the future price sensitive dr load levels would constantly change in response to dynamic real time prices which will impact the economic dispatch ed schedule and in turn affect electricity market clearing prices this paper adopts two methods for examining the impacts of different dr price elasticity characteristics and dr participation levels on the convergence of volatile power market a closed loop iterative simulation method and a non iterative method based on the contraction mapping theorem in this paper convergence refers to the fact that load and or price values will finally converge to a fixed point after a finite number of iterations between the ed problem and the price sensitive dr load adjustment five price sensitive dr performance function categories are used to simulate different nonlinear price elasticity characteristics of dr loads numerical studies illustrate how the convergence status of power markets will be affected by the nonlinear price elasticity dr curves the dr penetration levels and the capacity limits of generating units

self fulfilling deflations abstract what types of monetary and fiscal policy rules produce self fulfilling deflationary paths that are monotonic and empirically relevant this paper presents simple theoretical conditions that guarantee the existence of these paths in a general equilibrium model with sticky prices these sufficient conditions are weak enough to be satisfied by most monetary and fiscal policy rules a quantification of the model which combines a real shock a la hayashi and prescott 2002 with a simultaneous sunspot that deanchors inflation expectations matches the main empirical features of the japanese deflationary process during the lost decade the results also highlight the key role of the assumption about the anchoring of inflation expectations for the size of fiscal multipliers and in general for any policy analysis

local identification in dsge models abstract the issue of identification arises whenever structural models are estimated lack of identification means that the empirical implications of some model parameters are either undetectable or indistinguishable from the implications of other parameters therefore identifiability must be verified prior to estimation this paper provides a simple method for conducting local identification analysis in linearized dsge models estimated in both full and limited information settings in addition to establishing which parameters are locally identified and which are not researchers can determine whether the identification failures are due to data limitations such as lack of observations for some variables or whether they are intrinsic to the structure of the model the methodology is illustrated using a medium scale dsge model

speculative runs on interest rate pegs abstract we analyze a new class of equilibria that emerges when a central bank conducts monetary policy by setting an interest rate as an arbitrary function of its available information and letting the private sector set the quantity traded these equilibria involve a run on the central bank s interest target whereby money grows fast private agents borrow as much as possible against the central bank and the shadow interest rate is different from the policy target we argue that these equilibria represent a particular danger when banks hold large excess reserves such as is the case following periods of quantitative easing our analysis suggests that successfully managing the exit strategy requires additional tools beyond setting interest rate targets and paying interest on reserves in particular freezing excess reserves or fiscal policy intervention may be needed to fend off adverse expectations

step away from the zero lower bound small open economies in a world of secular stagnation abstract we study how small open economies can escape from deflation and unemployment in a situation where the world economy is permanently depressed building on the framework of eggertsson et al 2016 we show that the transition to full employment and at target inflation requires real and nominal depreciation of the exchange rate however because of adverse income and valuation effects from real depreciation the escape has a beggar thy self effect that may end up lowering welfare while eliminating underemployment we show that as long as the economy remains financially open domestic asset supply policies or reducing the effective lower bound on policy rates may be ineffective or even counterproductive however closing domestic capital markets does not necessarily enhance the monetary authorities ability to rescue the economy from stagnation

solving endogenous regime switching models abstract this paper solves rational expectations models in which structural parameters switch across multiple regimes according to state dependent endogenous transition probabilities assuming small shocks and smooth transition probabilities we apply a perturbation approach we first provide for conditions under which a unique bounded equilibrium exists we then compute first and second order approximations in a new keynesian model with monetary policy switching we document new effects of monetary policy switching when transition probabilities depend on inflation

on ex post pricing in the real time electricity market this paper proposes a new framework in calculating the ex post prices for the spot electricity market the proposed method finds a set of prices that are as consistent as possible with the actual outputs of resources correctly following their dispatch instructions two alternative consistency metrics are proposed in the paper one measures the difference between the actual performance of an individual resource and its bid based profit maximizing response to the ex post prices in a perfectly competitive market another measures the difference between the ex post price and the price that supports the actual response of an individual resource compared to the existing approaches adopted in the real time electricity markets in the u s the proposed method solves the ex post energy and ancillary service prices directly and simultaneously it does not require heuristics that are hard to justify and has a much clear definition for the pricing problem than the existing approaches do moreover the proposed approach is flexible in the price control required by the market operators numerical examples are presented to further demonstrate the validity of this approach

international exchange a foundation for theory building in international business there does not appear to be a consensus concerning what is the conceptual domain of international business this paper argues that this is due in part to an emphasis on the firm as the unit of analysis it is further argued that a comprehensive generative and theoretically integrative definition of international business could be established if exchange were made the unit of analysis by using the political economy paradigm and the various concepts of exchange adopted by the social sciences nine characteristics are identified and developed which uniquely define the conceptual domain of international business
