activist monetary policy imperfect capital mobility and the overshooting hypothesis abstract the hypothesis of exchange rate overshooting is investigated in the context of a model that incorporates activist monetary policy variable output imperfect capital mobility and slow price adjustment monetary policy which accommodates prices and or interest rates is shown to increase the probability of undershooting using constrained maximum likelihood methods the model is estimated for germany and japan since the advent of generalized floating in 1973 based on the estimated parameter values the mark exhibits overshooting while the yen is characterized by undershooting the constraints implied by the model cannot be rejected at standard significance levels for either country

optimal fiscal and monetary policy with occasionally binding zero bound constraints abstract this paper studies optimal fiscal and monetary policy when the nominal interest rate is subject to the zero lower bound zlb constraint in a stochastic new keynesian economy in the baseline model calibrated to match key features of the u s economy it is optimal for the government to increase its spending when at the zlb in the stochastic environment by about 60 percent more than it would in the deterministic environment the presence of uncertainty creates a unique time consistency problem if the steady state is inefficient although access to government spending policy increases welfare in the face of a large deflationary shock it decreases welfare during normal times as the government reduces the nominal interest rate less aggressively before reaching the zlb

foreign direct investment intra firm trade and ownership structure abstract asymmetric information about true opportunity cost in trade between a multinational and its foreign affiliate can alleviate the hold up problem in foreign direct investment selling shares in the affiliate to locals is also beneficial because it increases the parent multinational s information rent that is protected from a host government s confiscatory taxation

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

a model of fiscal dominance under the reinhart conjecture abstract this paper proposes some simple models where the central bank trades off between stabilizing the business cycle and targeting inflation to a level that stabilizes the public debt ratio we show that in a closed economy fiscal dominance does not necessarily imply hyperinflation moreover in an open economy it is successful in lowering debt ratios when output is reactive enough to unconventional monetary policy and when the expectations of future inflation are well anchored to the debt stabilization inflation target we show that the dynamics of both inflation and public debt ratio are described by first difference equations with time varying coefficients we provide some conditions for the asymptotic solutions of the long run steady states in particular we define two regimes of respectively strong and weak fiscal dominance depending upon whether or not the central bank s action ensures both the sustainability and the speed of convergence of debt to its long term level

activist monetary policy and exchange rate overshooting the deutsche mark dollar rate abstract after a decade of generalized floating it is clear that bilateral exchange rates exhibit more variability than the economic aggregates relative prices incomes and money supplies which generally comprise the fundamentals of theories of exchange rate determination dornbusch s overshooting hypothesis is the best known explanation of this phenomenon this paper shows that accommodative monetary policy with respect to prices has the potential to cause the economy to switch from exchange rate overshooting to undershooting using constrained maximum likelihood methods the model is estimated for germany and the united states the results provide strong evidence in support of the overshooting hypothesis for the deutsche mark dollar exchange rate

the risky steady state we propose a simple quantitative method to linearize around the risky steady state of a small open economy unlike when the deterministic steady state is used the net foreign asset position is well defined we allow for stochastic income and stochastic interest rate

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

monetary policy when interest rates are bounded at zero this paper assesses the importance of the zero lower bound on nominal interest rates for the interest rate channel of monetary policy we simulate several interest rate setting policy rules with ei

attenuating the forward guidance puzzle implications for optimal monetary policy abstract we examine the implications of less powerful forward guidance for optimal policy using a sticky price model with an effective lower bound elb on nominal interest rates as well as a discounted euler equation and a discounted phillips curve when the private sector agents discount future economic conditions more in making their decisions today a future rate cut becomes less effective in stimulating current economic activity under a wide range of plausible degrees of discounting it is optimal for the central bank to compensate for the reduced effect of a future rate cut by keeping the policy rate at the elb for longer

discretionary monetary policy and the zero lower bound on nominal interest rates abstract ignoring the existence of the zero lower bound on nominal interest rates one considerably understates the value of monetary commitment in new keynesian models a stochastic forward looking model with an occasionally binding lower bound calibrated to the u s economy suggests that low values for the natural rate of interest lead to sizeable output losses and deflation under discretionary monetary policy the fall in output and deflation are much larger than in the case with policy commitment and do not show up at all if the model abstracts from the existence of the lower bound the welfare losses of discretionary policy increase even further when inflation is partly determined by lagged inflation in the phillips curve these results emerge because private sector expectations and the discretionary policy response to these expectations reinforce each other and cause the lower bound to be reached much earlier than under commitment

the persistence of the peso problem when policy is noisy abstract the peso problem the market s belief that a discrete event may occur has frequently been blamed for the persistence of on average mistaken forecasts of macroeconomic variables this paper demonstrates how beliefs that a policy process may have switched can induce apparent ex post biased forecasts of exchange rates even after the switch has occurred furthermore during this peso problem period exchange rates may appear to contain a speculative bubble component since they will systematically deviate from the levels implied by observing fundamentals ex post and the conditional variance of exchange rates will exceed the variance implied by observing fundamentals

a welfare based analysis of international monetary policy spillovers at the zero lower bound we study the welfare effects of international monetary policy spillovers at the zero lower bound focusing on the effects of forward guidance in a large economy foreign on its smaller trading partner home in scenarios motivated by the global financial crisis we find that foreign forward guidance has an overall prosper thy neighbor effect on the home economy as long as it increases foreign welfare this finding holds under alternative assumptions about exchange rate pass through or the degree of international financial integration however foreign forward guidance may worsen the trade off between the stabilization objectives of home monetary policy

exchange rate hysteresis large versus small policy misalignments abstract using a monetary model in the spirit of dornbusch 1976 and a sunk cost model of trade hysteresis we show that a sufficiently large policy misalignment can induce hysteresis in the trade balance and thereby alter the steady state real exchange rate hence exchange rate dynamics are path dependent since hysteresis in our model can entail industrial dislocation and the scrapping of sunk assets we suggest that these factors constitute a welfare cost of large policy misalignments that have not been considered formally additionally since the long run exchange rate is path dependent standard empirical tests of exchange rate models may involve a misspecification

endogenous transfer pricing and the effects of uncertain regulation abstract a scenario is constructed under which a multinational firm mnf faces a threat of a penalty the probability of which is based on the mnf s transfer price given this scenario the mnf s optimum transfer price could be in the interior and simultaneous interaction of the transfer price and real variables exists increased surveillance of the transfer price makes the mnf move its transfer price towards the arm s length price and checks fiscal abuses but it worsens the international allocation of resources even though the cost advantage of the exporting country increases still the impact on global welfare is ambiguous

a new keynesian perspective on the great recession with an estimated new keynesian model this paper compares the great recession of 2007 09 to its two immediate predecessors in 1990 91 and 2001 the model attributes all three downturns to a similar mix of aggregate demand and supply disturbances the most recent series of adverse shocks lasted longer and became more severe however prolonging and deepening the great recession in addition the zero lower bound on the nominal interest rate prevented monetary policy from stabilizing the us economy as it had previously counterfactual simulations suggest that without this constraint output would have recovered sooner and more quickly in 2009 jel e32 e52

fiscal activism and the zero nominal interest rate bound in an economy where the zero lower bound on nominal interest rates is an occasionally binding constraint and the government lacks a commitment technology it may be desirable for society to appoint a policymaker who cares less about government spending stabilization relative to inflation and output gap stabilization than the private sector does a policymaker of this type uses government spending more elastically to stabilize the economy at the zero lower bound the anticipation of aggressive fiscal expansions in future liquidity trap situations increases inflation expectations and lowers real interest rates thereby mitigating the decline in output and inflation

a general unconstrained model for transfer pricing in multinational supply chains multinational supply chains operate in more than one country or tax jurisdiction and face decision problems concerned with trade flows of resources products and services transfer prices and allocation of transport costs between their divisions these decisions must consider for the sake of optimality corporate and governmental parameters such as the payment of dividends and royalties ownership of and control over subsidiaries income taxes differentials duties and quotas etc in this paper we generalize and extend the theory of the multinational firm to the case of multinational supply chains we propose a model that is more general and comprehensive than the previous ones proposed in the literature to be more specific our model integrates many of the previous research factors and includes new ones such as transport costs and duty drawbacks which are critical for supply chains that operate under international trade regulations under the maximization of the repatriated earnings objective we study the optimality conditions of the corporate decision variables to derive managerial guidelines and to determine how decisions regarding trade quantities transfer prices and transport cost allocations affect the amount of taxes to be paid to host governments as well as the total after tax repatriated earnings of the corporation

government debt and optimal monetary and fiscal policy how do different levels of government debt affect the optimal conduct of monetary and fiscal policies and what do these optimal policies imply for the evolution of government debt over time to provide an answer this paper studies a standard monetary policy model with nominal rigidities and monopolistic competition and adds to it a fiscal authority that issues nominal non state contingent debt levies distortionary labor income taxes and determines the level of public goods provision higher government debt levels make it optimal to reduce public spending so as to dampen the adverse incentive effects of distortionary taxes but also strongly influence the optimal stabilization response following technology shocks in particular higher debt levels give rise to larger risks to the fiscal budget and to tax rates this makes it optimal to reduce government debt over time the optimal speed of debt reduction is missed when using first order approximations to optimal policies but is shown to be quantitatively significant in a second order approximation especially when technology movements are largely unpredictable in nature

monetary policy and the lost decade lessons from japan i investigate how monetary policy can avoid a deflationary slump when policy rates are near zero by studying interest rate policy during japan s lost decade estimation results suggest that the bank of japan s interest rate policy fits a conventional reaction function with an inflation target near 1 the disapointing economic performance thus seems primarily due to adverse economic shocks rather than extraordinary policy errors also counterfactual policy simulations suggest that simply raising the inflation target would not have substantially improved performance however price level targeting or combining a higher inflation target with an aggressive output response would have achieved superior stabilization results

reliability of policy announcements and the effects of monetary policy abstract monetary authorities regularly announce targets for monetary growth but the market may not completely trust these announcements because they may not always be truthful hence the market does not have perfect knowledge about future monetary policy and must form its expectations on the basis of information it can extract from the announcements and its observations of the actual money supply this paper asks how the macroeconomic effect of monetary policy might be altered by more reliable policy announcements in the setting of a medium sized open economy it is found that contrary to the full information case a reduction in monetary growth of 1 may lead on impact to a reduction in inflation of much less than 1 if the announcements are not very credible the output costs of lowering inflation are smaller both in the short run and the long run the more reliable the announcements however the plausibility of announcements does not affect the output loss for a given appreciation of the currency fluctuations in the exchange rate that are attributable to monetary disturbances beyond the policy makers control can nonetheless be dampened by making announcements that are more highly correlated with the truth

fiscal sustainability in a new keynesian model recent work on optimal monetary and fiscal policy in new keynesian models suggests that it is optimal to allow steady state debt to follow a random walk in this paper we consider the nature of the time inconsistency involved in such a policy and its implication for discretionary policymaking we show that governments are tempted given inflationary expectations to utilize their monetary and fiscal instruments in the initial period to change the ultimate debt burden they need to service we demonstrate that this temptation is only eliminated if following shocks the new steady state debt is equal to the original efficient debt level even though there is no explicit debt target in the government s objective function analytically and in a series of numerical simulations we show which instrument is used to stabilize the debt depends crucially on the degree of nominal inertia and the size of the debt stock we also show that the welfare consequences of introducing debt are negligible for precommitment policies but can be significant for discretionary policy finally we assess the credibility of commitment policy by considering a quasi commitment policy which allows for different probabilities of reneging on past promises

optimal monetary and fiscal policy with a zero bound on nominal interest rates i characterize optimal monetary and fiscal policy in a stochastic new keynesian model when nominal interest rates may occasionally hit the zero lower bound the benevolent policymaker controls the short term nominal interest rate and the level of government spending under discretionary policy accounting for fiscal stabilization policy eliminates to a large extent the welfare losses associated with the presence of the zero bound under commitment the gains associated with the use of the fiscal policy tool remain modest even though fiscal stabilization policy is part of the optimal policy mix

risk premium shocks and the zero bound on nominal interest rates there appears to be a disconnect between the importance of the zero bound on nominal interest rates in the real world and predictions from quantitative dsge models recent economic events have reinforced the relevance of the zero bound for monetary policy whereas quantitative models suggest that the zero bound does not constrain optimal monetary policy

an equilibrium model of exchange rate determination and asset pricing with nontraded goods and imperfect information this paper presents a two country model with maximizing households stochastic production stochastic money growth and perfect capital mobility because of the presence of nontraded goods households in different countries consume different goods analytic solutions are presented for the nominal exchange rate the real exchange rate nominal interest rates and real interest rates it is shown that the model is compatible with some important features of the real world behavior of exchange rates when households are imperfectly informed about the distribution of money growth the exchange rate exhibits patterns of overshooting and is more volatile than the ratio of the money stocks copyright 1987 by university of chicago press

exchange rate dynamics an empirical investigation this paper estimates a reduced form exchange rate equation whose estimates are used to address questions on exchange rate overshooting intermediate run exchange rate dynamics and long run proportionality relationships between relative money supplies and exchange rates based on swiss u s data from the period 1973 79 the major findings are that following a monetary shock there is short run exchange rate overshooting by a factor of about two and that subsequent exchange rate adjustments to a new long run equilibrium take longer than 2 years and exhibit nonmonotonic patterns

optimal monetary policy under commitment with a zero bound on nominal interest rates we determine optimal monetary policy under commitment in a forwardlooking new keynesian model when nominal interest rates are bounded below by zero the lower bound represents an occasionally binding constraint that causes the model and optimal policy to be nonlinear a calibration to the u s economy suggests that policy should reduce nominal interest rates more aggressively than suggested by a model without lower bound rational agents anticipate the possibility of reaching the lower bound in the future and this amplifies the effects of adverse shocks well before the bound is reached while the empirical magnitude of u s mark up shocks seems too small to entail zero nominal interest rates shocks affecting the natural real interest rate plausibly lead to a binding lower bound under optimal policy however this occurs quite infrequently and does not imply positive average inflation rates in equilibrium interestingly the presence of binding real rate shocks alters the policy response to non binding markup shocks

monetary and fiscal policy in a liquidity trap with inflation persistence abstract this paper relies on the new keynesian model with structural inflation persistence to characterize the optimal monetary and fiscal policy in a liquidity trap it shows that with a phillips curve that is both forward and backward looking the monetary policy that is implemented during a liquidity trap episode can be sufficient to avoid a depression the central bank does not need to commit beyond the end of the crisis to get some traction on economic activity regarding fiscal policy inflation persistence justifies some front loading of government expenditures to get inflation started such as to reduce the real interest rate the magnitude of the optimal fiscal stimulus is decreasing in the degree of inflation persistence finally if inflation persistence is due to adaptive expectations rather than to price indexation then monetary policy is ineffective while the optimal fiscal stimulus is large and heavily front loaded

new keynesian dynamics in a low interest rate environment recent research has found that the dynamic properties of the new keynesian model are unorthodox when the nominal interest rate is zero improvements in technology and reductions in the labor tax rate lower economic activity and the size of the government purchase output multiplier is very large this paper provides evidence that these results are not empirically relevant we show that a prototypical new keynesian model fit to japanese data exhibits orthodox dynamics during japan s episode with zero interest rates we then demonstrate that this specification is more consistent with outcomes in japan than alternative specifications that have unorthodox properties

company tax reform with a water s edge this paper analyzes the effects of switching from a corporate tax system based on separate accounting sa towards a system in which two countries form a formula apportionment fa union while a third country sticks to sa water s edge our analysis draws a positive picture on the water s edge regulation in the short run for given tax rates the transition from sa to fa is likely to reduce profit shifting from the fa union to non fa tax havens in a long run tax competition analysis we find a negative water s edge externality under fa that tends to be less detrimental than the profit shifting externality under sa and may offset other externalities under fa

foreign subsidiary transfer pricing and tariffs in the transfer pricing literature horst 12 concludes that the multinational firm mnf will generally charge a low transfer price ltp while other authors are ambivalent on this question this paper shows that less than whole ownership over the subsidiary generally makes the mnf change its transfer pricing strategy from desiring a ltp to wanting a high transfer price htp the conditions for an htp are fairly broad so that we are more likely to observe it than has been suggested in the literature the mnf literature also presumes that the host country loses revenue due to an htp however this view ignores the effects of tariffs on a government s revenue if tariff revenue is included an htp can increase the host country s revenue

the formation of consumer inflation expectations new evidence from japan s deflation experience using a new data set we investigate the relationship between the inflation experience and expectations of households in japan focusing on the post 1995 deflationary era our first finding is that inflation expectations increase with age second we find that measured inflation rates also increase with age although age and inflation expectations continue to exhibit a positive correlation even after controlling for the household level inflation rate analysis suggests that the correlation between age and inflation expectations is driven largely by the correlation between cohort and inflation expectations which we interpret to represent the effect of historical inflation experience on inflation expectations

dealing with a liquidity trap when government debt matters optimal time consistent monetary and fiscal policy how does the need to preserve government debt sustainability affect the optimal monetary and fiscal policy response to a liquidity trap to provide an answer we employ a small stochastic new keynesian model with a zero bound on nominal interest rates and characterize optimal time consistent stabilization policies we focus on two policy tools the short term nominal interest rate and debt financed government spending the optimal policy response to a liquidity trap critically depends on the prevailing debt burden while the optimal amount of government spending is decreasing in the level of outstanding government debt future monetary policy is becoming more accommodative triggering a change in private sector expectations that helps to dampen the fall in output and inflation at the outset of the liquidity trap

liquidity traps capital flows abstract motivated by debates surrounding international capital flows during the great recession we conduct a positive and normative analysis of capital flows when a region of the global economy experiences a liquidity trap capital flows reduce inefficient output fluctuations in this region by inducing exchange rate movements that reallocate expenditure towards the goods it produces restricting capital mobility hampers such an adjustment from a global perspective constrained efficiency entails subsidizing capital flows to address an aggregate demand externality associated with exchange rate movements absent cooperation however dynamic terms of trade manipulation motives drive countries to inefficiently restrict capital flows impeding aggregate demand stabilization

unconventional fiscal policy at the zero bound when the zero lower bound on nominal interest rates binds monetary policy cannot provide appropriate stimulus we show that in the standard new keynesian model tax policy can deliver such stimulus at no cost and in a time consistent manner there is no need to use inecient policies such as

deficits public debt dynamics and tax and spending multipliers cutting government spending can increase the budget defi cit at zero interest rates according to a standard new keynesian model calibrated with bayesian methods similarly increasing sales taxes can increase the budget defi cit rather than reduce it both results suggest limitations of austerity measures at zero interest rates running budget defi cits can be either expansionary or contractionary depending on how they interact with expectations about long run taxes and spending the effect of fi scal policy action is thus highly dependent on the policy regime a successful stimulus therefore needs to specify how the budget is managed not only in the short but also in the medium and long runs

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

whence exchange rate overshooting money stock or flow abstract money stock innovations have two principal impact effects on the exchange rate one is the direct effect as captured by the overshooting hypothesis the second is the result of the change in money growth rate expectations induced by the stock innovation simulations using a stylized monetary process verify that the front end loading of the growth rate effect is potentially much more important that the direct effect additional simulations using a calibrated monetary process demonstrate that growth rate effects are on average about twice the magnitude of stock innovation effects

an optimizing is lm specification for monetary policy and business cycle analysis we ask whether relations of the is lm type can sensibly be used for the aggregate demand portion of a dynamic optimizing general equilibrium model intended for analysis of issues regarding monetary policy and cyclical fluctuations the main result is that only one change the addition of a term regarding expected future income is needed to make the is function match a fully optimizing model whereas no changes are needed for the lm function this modification leads to a dynamic forward looking model of aggregate demand that is tractable and usable with a wide variety of aggregate supply specifications theoretical applications concerning price level determinacy and gradual price adjustment are included

perverse intra firm trade this paper shows that linkages between domestic costs and direction of intra firm trade break down when the multinational firms mnfs face tax rate differentials thus in the context of mnfs conclusions drawn on the assumption of equal or nonexistent tax rates cannot be assumed to extend to the general case of unequal tax rates further saving on profit taxes itself can be a powerful motive for internalisation

nonlinear adventures at the zero lower bound abstract in this paper we argue for the importance of explicitly considering nonlinearities in analyzing the behavior of the new keynesian model with a zero lower bound zlb of the nominal interest rate to show this we report how the decision rules and the equilibrium dynamics of the model are substantially affected by the nonlinear features brought about by the zlb we also illustrate a tension between the length of a spell at the zlb and the drop in consumption there

multinational firms and government revenues abstract underinvoicing of intrafirm exports by a multinational firm mnf can increase the exporting country s revenue overinvoicing can increase the importing country s revenue when its tariff rate is higher than its profit tax rate and both countries revenues may change in the same direction transfer pricing increases the mnf s global tax burden unambiguously when the home profit tax rate is not smaller than the foreign and the mnf overinvoices and can increase it in other cases this last result arises when increase in the level of intrafirm trade which accompanies transfer pricing and or non wholly owned subsidiary are considered

optimal debt management in a liquidity trap we study optimal debt management in the face of shocks that can drive the economy into a liquidity trap and call for an increase in public spending in order to mitigate the resulting recession our approach follows the literature of macroeconomic models of debt management which we extend to the case where the zero lower bound on the short term interest rate may bind we wish to identify the conditions under which removing long maturity government debt from the secondary market can be an optimal policy outcome we show that the optimal debt management strategy is to issue short term debt if the government faces a sizable exogenous increase in public spending and if its initial liability is not very large in this case our results run against the standard prescription of the debt management literature in contrast if the initial debt level is high then issuing long term government bonds is optimal finally we find a role for revisions in the debt management strategy during lt episodes whereby the government actively manages the maturity structure in some cases removing long bonds from the secondary market

optimal monetary policy at the zero interest rate bound what should a central bank do when faced with a weak aggregate demand even after reducing the short term nominal interest rate to zero to address this question we solve a central bank s intertemporal loss minimization problem in which the non negativity constraint on nominal interest rates is explicitly considered we find that the optimal path is characterized by policy inertia in the sense that a zero interest rate policy should be continued for a while even after the natural rate of interest returns to a positive level by making such a commitment the central bank is able to achieve higher expected inflation lower long term nominal interest rates and a weaker domestic currency in the adverse periods when the natural rate of interest significantly deviates from a steady state level

eliminating a deflationary trap through superinertial interest rate rules abstract this paper demonstrates that even in the presence of a zero lower bound on nominal interest rates central banks can eliminate a deflationary trap by the conduct of interest rate rules that have superinertia

corporate income taxation of multinationals in a general equilibrium model abstract this paper contributes to the discussion on separate accounting versus formula apportionment in the corporate income taxation of multinational enterprises the innovation is that we consider a general equilibrium tax competition model with an endogenous interest rate in contrast to previous studies we show that tax rates are inefficiently low not only under separate accounting but also under formula apportionment moreover we identify a wide range of empirically relevant cases where formula apportionment is superior to separate accounting independent of the magnitude of the concealment cost of profit shifting the reason for the change in results is that one country s tax rate affects other countries additionally via changes in the interest rate

the perils of nominal targets a monetary authority can be committed to pursuing an inflation price level or nominal gdp target yet systematically fail to achieve the prescribed goal constrained by the zero lower bound on the policy rate the monetary authority is unable to implement its objectives when private sector expectations stray far enough from the target low inflation expectations become self fulfilling resulting in an additional markov equilibrium in which the monetary authority falls short of the nominal target average output is below its efficient level and the policy rate is typically low introducing a stabilization goal for long term nominal rates can implement a unique markov equilibrium without fully compromising stabilization policy

is there a fiscal free lunch in a liquidity trap this paper uses a dsge model to examine the eects of an expansion in government spending in a liquidity trap the spending multiplier can be much larger than in the normal situation if the liquidity trap is very persistent and scal stimulus can be rapidly implemented moreover the budgetary costs may be minimal as the large response of output boosts tax revenues allowing for something close to a scal free lunch however we caution that the multiplier may be much smaller under plausible implementation lags for many types of public spending and or if the liquidity trap lasts less than two years in addition because the marginal impact of scal expansion decreases in the scale of the outlay it is crucial to distinguish between average and marginal multipliers

interest rates and monetary policy uncertainty abstract this paper analyzes a model in which optimizing households are uncertain about monetary policy and learn about it over time in this model the variance of changes in nominal and ex post real interest rates increases with the variance of the household s predictive distribution over money growth a positive relation between unexpected changes in nominal interest rates and the money stock results from monetary policy uncertainty finally if money growth covaries negatively with real wealth an increase in monetary policy uncertainty increases the expected real rate of interest and decreases the nominal rate of interest

the deflation bias and committing to being irresponsible i model deflation at zero nominal interest rate in a microfounded general equilibrium model i show that one can analyze deflation as a credibility problem if three conditions are satisfied first the government s only policy instrument is increasing the money supply by open market operations in short term bonds second the economy is subject to large negative demand shocks third the government cannot commit to future policy i call the credibility problem that arises under these conditions the deflation bias i propose several policies to solve it they all involve printing money or issuing nominal debt in addition they require cutting taxes buying real assets such as stocks or purchasing foreign exchange the government credibly commits to being irresponsible by pursuing these policies it commits to higher money supply in the future so that the private sector expects inflation instead of deflation this is optimal since it curbs deflation and increases output by lowering the real rate of return

optimal monetary policy and determinacy under active passive regimes abstract should one expect inflation to be stable when monetary policy is passive according to the workhorse model for monetary policy analysis the answer should be no if the passive spell is too long in this paper i develop a new keynesian model in which monetary policy is optimal subject to a loose commitment constraint i show that there is a threshold degree of commitment such that the equilibrium is locally unique when monetary policy switches between active and passive stances regardless of the length of the passive spell this result also holds for a version of the model where the passive spell is endogenous and due to a demand shock driving the economy to the zero lower bound

a model of exchange rate dynamics this model treats the exchange rate as an asset price that depends on expectations concerning exogenous real and monetary factors that will affect relative prices and absolute price levels in future periods changes in exchange rates reflect both expected changes in these exogenous factors and changes in expectations occasioned by new information the model explains the random component in exchange rate behavior the source of divergences from purchasing power parity the anticipatory response of exchange rates to future expected disturbances and the causes of exchange rate overshooting

optimal fiscal and monetary policy under sticky prices this paper studies optimal fiscal and monetary policy under sticky product prices the theoretical framework is a stochastic production economy without capital the government finances an exogenous stream of purchases by levying distortionary income taxes printing money and issuing one period nominally risk free bonds the main findings of the paper are first for a miniscule degree of price stickiness i e many times below available empirical estimates the optimal volatility of inflation is near zero this result stands in stark contrast with the high volatility of inflation implied by the ramsey allocation when prices are flexible the finding is in line with a recent body of work on optimal monetary policy under nominal rigidities that ignores the role of optimal fiscal policy second even small deviations from full price flexibility induce near random walk behavior in government debt and tax rates third sluggish price adjustment raises the average nominal interest rate above the one called for by the friedman rule finally an interest rate feedback rule whereby the nominal interest rate depends on inflation and output fits well the data emanating from the ramsey economy however the fitted rule is not of the taylor type for the implied inflation coefficient is less than one and close to zero and the output coefficient is negative jel classification e52 e61 e63

transfer pricing regulation and tax competition abstract the paper analyzes multinational enterprises incentives to manipulate internal transfer prices to take advantage of tax differences across countries and implications of transfer pricing regulations as a countermeasure against such profit shifting we find that tax motivated foreign direct investment fdi may entail inefficient internal production but may benefit consumers thus encouraging transfer pricing behavior to some extent can enhance social welfare furthermore we consider tax competition between two countries to explore its interplay with transfer pricing regulations we show that the fdi source country will be willing to set a higher tax rate and tolerate some profit shifting to a tax haven country if the regulation is tight enough we also indicate a novel mechanism through which it is the larger country that undertakes tax motivated fdi the pattern we often observe in reality

the multinational firm with arm s length transfer price limits abstract a multinational firm faced with arm s length limitations on its transfer prices is examined where the limitations are determined by the firm s marginal cost and intracountry prices such a firm is shown to manipulate its production and sales in order to gain a more desirable transfer price comparative static results develop policy implications not found in simpler models which often assume the firm to be constrained by arm s length limits but to be unaware of the effects of its actions on the limits

monetary conservatism and fiscal policy abstract does an inflation conservative central bank a la rogoff 1985 remain desirable in a setting with endogenous fiscal policy to provide an answer we study monetary and fiscal policy games without commitment in a dynamic stochastic sticky price economy with monopolistic distortions monetary policy determines nominal interest rates and fiscal policy provides public goods generating private utility we find that lack of fiscal commitment gives rise to excessive public spending the optimal inflation rate internalizing this distortion is positive but lack of monetary commitment generates too much inflation a conservative monetary authority thus remains desirable when fiscal policy is determined before monetary policy each period the monetary authority should focus exclusively on stabilizing inflation monetary conservatism then eliminates the steady state biases associated with lack of monetary and fiscal commitment and leads to stabilization policy that is close to optimal

the optimal monetary policy rule under the non negativity constraint on nominal interest rates abstract we identify a monetary policy rule that remains optimal even in the presence of the non negativity constraint on nominal interest rates this rule also compensates for any past shortfalls in monetary easing during the zero interest rate period

company taxation and tax spillovers separate accounting versus formula apportionment it is observed in the real world that taxes matter for location decisions and that multinationals shift profits by transfer pricing the us and canada use so called formula apportionment fa to tax corporate income and the eu is debating a switch from separate accounting sa to fa this paper develops a theoretical model that compares basic properties of fa to sa the focal point of the analysis is how changes in tax rates affect capital formation input choice and transfer pricing as well as on spillovers on tax revenue in other countries the analysis shows that a move from sa to fa will not eliminate such spillovers and will in cases identified in the paper actually aggravate them

real exchange rate overshooting and the output cost of bringing down inflation implementing a gradualist policy of monetary contraction in an open economy with a freely floating exchange rate but with nominal inertia in domestic labor costs can lead to prompt and substantial changes in the nominal and real exchange rate one of the virtues claimed for such exchange rate overshooting however is its immediate effect on the price level and so on domestic wage and price inflation in this paper we show that in a model which is super neutral and has nominal inertia in both the level of labor costs and their trend or core rate of growth this early overshooting of the exchange rate does not succeed in cutting the output costs of reducing steady state inflation those output and unemployment costs which are initially avoided by over valuing the currency have to be paid later when this overvaluation is corrected relative to other policies which achieve the same effect on steady state inflation exchange rate overshooting brings inflation down more quickly this abstract was borrowed from another version of this item

exchange rate flexibility under the zero lower bound an independent monetary policy and a flexible exchange rate generally help a country in adjusting to macroeconomic shocks but recently in many countries interest rates have been pushed down close to the lower bound limiting the ability of policy makers to accommodate shocks even with flexible exchange rates this paper argues that when the zero bound constraint on nominal interest rates is binding and policy lacks an effective forward guidance mechanism a flexible exchange rate system may be inferior to a single currency area with monetary policy constrained by the zero bound a flexible exchange rate exacerbates the impact of shocks remarkably this may hold true even if only a subset of countries are constrained by the zero bound and other countries optimally adjust their interest rate targets for a regime of multiple currencies to dominate a single currency in a zero bound environment it is necessary to have effective forward guidance in monetary policy
