debt regimes and the effectiveness of monetary policy abstract this paper develops a medium scale non linear model of the us economy our proposed model a threshold vector autoregression with stochastic volatility assumes that changes in government debt to gdp ratios drive the transition between regimes capturing low and high debt regimes the introduction of hierarchical priors enables us to flexibly shrink the empirical model towards the moments implied by a dynamic stochastic general equilibrium model in the empirical application we analyze regime specific monetary policy shocks our findings indicate that the effect of monetary policy is less pronounced in high debt regimes pointing towards differences in the underlying monetary policy transmission mechanisms forecast error variance decompositions enable us to shed further light on the relative importance of monetary policy shocks within different debt regimes in terms of explaining the variance of forecast errors

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

secular cost changes and the size of government towards a generalized theory abstract baumol s cost disease account of government growth is contrasted with that of kau and rubin who focus on decreasing costs of tax collection over time the apparent paradox wherein the first theory explains government growth by cost increases and the second by way of cost decreases is technically resolved why both theories seem to be able to stand up to empirical tests even though they use similar data is then explained finally public choice analysis is employed to reveal further potential for the ultimate construction of one all embracing secular cost change theory of government growth

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

on the estimation of demand systems through consumption efficiency we consider a bayesian implementation of a new approach to estimating demand systems this approach suggested by varian 1990 is based on a generalization of afriat s 1967 e ciency index the model we propose leads to a very tractable posterior and predictive analysis yet allows for interesting economic interpretations we conduct a sensitivity analysis with respect to the prior in an application to annual aggregate u s consumption data and conclude that the sample is quite informative average e ciency and expected budget shares are examined in some detail

the concept of quality and the efficiency of markets for consumer products can consumers trust prices to be good quality indicators previous studies based on quality data from consumer reports have indicated that the relation of price to overall quality is quite weak this paper demonstrates that these studies are methodologically invalid by showing that the concept of overall quality has many dimensions to what extent do inefficient variants occur in the market previous studies have suggested that there is a considerable degree of inefficiency in the market alternative calculations imply that inefficient variants are in fact frequent but that the loss to consumers is much lower than previously suggested

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

the dynamics of sovereign debt crises and bailouts abstract motivated by the recent european debt crisis this paper investigates the scope for a bailout guarantee in a sovereign debt crisis defaults may arise from negative income shocks government impatience or a sunspot coordinated buyers strike we introduce a bailout agency and characterize the strategy with the minimal actuarially fair intervention which guarantees the no buyers strike fundamental equilibrium relying on the market for residual financing the intervention makes it cheaper for governments to borrow inducing them borrow more leaving default probabilities possibly rather unchanged the maximal backstop will be pulled precisely when fundamentals worsen

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

a probability based stress test of federal reserve assets and income to support the economy the federal reserve amassed a large portfolio of long term bonds we assess the fed s associated interest rate risk including potential losses to its treasury securities holdings and declines in remittances to the treasury unlike past examinations of this interest rate risk we attach probabilities to alternative interest rate scenarios these probabilities are obtained from a dynamic term structure model that respects the zero lower bound on yields the resulting probability based stress test finds that the fed s losses are unlikely to be large and remittances are unlikely to exhibit more than a brief cessation

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

the dire effects of the lack of monetary and fiscal coordination abstract if the government s willingness to stabilize debt is waning while the central bank is adamant about keeping inflation low the economy enters a vicious spiral of higher inflation monetary tightening recession and further debt accumulation the mere possibility of this conflict represents a drag on the economy a commitment to inflate away the debt accumulated during a large recession leads to welfare improvements and lower uncertainty by separating long run fiscal sustainability from the short run fiscal stimulus this strategy can be used to avoid the zero lower bound as a technical contribution we explain how to build shock specific policy rules

financial innovation and the transactions demand for cash we document cash management patterns for households that are at odds with the predictions of deterministic inventory models that abstract from precautionary motives we extend the baumol tobin cash inventory model to a dynamic environment that allows for the possibility of withdrawing cash at random times at a low cost this modification introduces a precautionary motive for holding cash and naturally captures developments in withdrawal technology such as the increasing diffusion of bank branches and atm terminals we characterize the solution of the model which qualitatively reproduces several empirical patterns we estimate the structural parameters using micro data and show that quantitatively the model captures important economic patterns the estimates are used to quantify the expenditure and interest rate elasticity of money demand the impact of financial innovation on money demand the welfare cost of inflation and the benefit of atm ownership

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

did women s suffrage change the size and scope of government this paper examines the growth of government during this century as a result of giving women the right to vote using cross sectional time series data for 1870 1940 we examine state government expenditures and revenue as well as voting by u s house and senate state delegations and the passage of a wide range of different state laws suffrage coincided with immediate increases in state government expenditures and revenue and more liberal voting patterns for federal representatives and these effects continued growing over time as more women took advantage of the franchise contrary to many recent suggestions the gender gap is not something that has arisen since the 1970s and it helps explain why american government started growing when it did

party polarization and the business cycle in the united states a large literature has studied the trend of greaterpolarization between democrats and republicans in congress this paper empirically examines the extent to which inflationand unemployment explain cyclical movements ofpolarization over time an informal application of thestandard downsian spatial competition model of partiesgenerates the following relationships ceteris paribus 1 inflation should be associated with policy convergence 2 unemployment should be associated with polarization 3 theeffect of unemployment on polarization should be larger inmagnitude than the effect of inflation on convergence and 4 the effect of unemployment on polarization should be strongerin the house than in the senate we estimate the relationshipbetween vote records and business cycle conditions over the1947 1999 period using a gls model with varying lags ourresults are broadly consistent with these business cyclehypotheses of polarization though greater support is found inhouse data than in senate data

measuring market efficiency and welfare loss this study presents a general methodology capable of addressing a number of fundamental questions in consumer policy are consumers paying more than the minimum price for a given bundle of attributes if so what brands cost more than the consumer needs to pay what would be the degree of improvement in the consumer s well being if some intervention sets the price of such inefficient brands at the efficient level we apply the methodology to data on atuomobiles and several other goods and analyze the determinants of efficiency

testing theories of real government size u s experience 1959 89 in a recent article west 17 argued that the existence of so many strands of analysis attempting to explain the growth of government calls ultimately for one consolidated or generalized theory accordingly he produced a model that integrated four such theories two on the cost side and two on the demand side the purpose of the present paper is to derive empirical measures of all four theories using u s data for the period 1959 1989 the presumption is that each one separately might contribute in its own way to a composite explanation of government growth and that what is currently most needed is a set of jointly determined empirical estimates showing relative importance while all our measures of government size consolidate federal state and local government expenditures two other measurement issues should be emphasized since they distinguish our work from other contributions to this literature the government component of our main dependent variable the real size of government is measured in two different ways the first uses the national accounts definition of government purchases which excludes transfer payments from the measure of size whereas the second includes final purchases plus net government transfer payments since we are interested in the effects of changes in the productivity of supplying government services the first of these definitions is expected to be more relevant and is so used as the basis of our empirical work however since there is a sense in which changes in the productivity of government may affect the output of transfers we also use the second definition to produce a more complete empirical exercise the other distinguishing feature of our analysis is that both definitions of government size are analyzed in real as distinct from the more usual nominal share of government in gross domestic product gdp this distinction becomes immediately more striking when it is pointed out that while most authors hitherto have attempted to explain the phenomenon of positive growth in the ratio of nominals over the past half century the ratio of reals has actually fallen for most of our

frontier production functions and technical efficiency measures the concept of technical efficiency is central to measuring the firm performance the measurement of technical efficiency has proved difficult and complex and the literature provides a range of methodologies this paper reviews the various methodologies for measuring technical efficiency and offers a comparison between established methods of measurements the discussion is literary with less mathematical jargons and equations the objective of this paper is not to be exhaustive but to be up to date and to provide a significant discussion on some of the core methods of measuring technical efficiency

comment on when does a central bank s balance sheet require fiscal support by marco del negro and christopher a sims abstract a central bank is insolvent if its plans imply a ponzi scheme on reserves so the price level becomes infinity if the central bank enjoys fiscal support in the form of a dividend rule that pays out net income every period including when it is negative it can never become insolvent independently of the fiscal authority otherwise this note distinguishes between intertemporal insolvency rule insolvency and period insolvency while period and rule solvency depend on analyzing dividend rules and sources of risk to net income evaluating intertemporal solvency requires overcoming the difficult challenge of measuring the present value of seignorage

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

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

estimating an hedonic translog cost function for the home health care industry medicare home health care plays an important role in providing cost effective care for the chronically ill and elderly long seen as a cost effective substitute for nursing home care home care has become even more important with expenditures increasing by 31 4 from 1990 to 1996 the purpose of this paper is to provide a short run cost analysis of a sample of home health care providers to gain insight into the efficient provision of home health care services this paper is a significant improvement over previous studies in that it uses a nationwide database to more accurately represent the multiproduct nature of the industry and uses an hedonic translog cost estimation with desirable economic properties

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

the impact of uncertainty on the feasibility of humphrey hawkins objectives a stochastic framework for coordination of macroeconomic policies is introduced in this paper it is suggested that i measures of policy accountability should allow for the climate of uncertainty that surrounds policy decisions and ii most models of aggregate economic activity impose arbitrary specifications of uncertainty that do not appear to be empirically justifiable ambiguities in interpreting the humphrey hawkins reports of policy authorities are sketched in section ii a proposal for maximizing the ex ante prospects of policy objectives is illustrated in section iii finally nonstationary allocations of uncertainty are discussed in sections iv and v

modelling time of day substitution using the second moments of demand time of day tod rates are a commonly used method for peak load pricing of many services such services as electricity communications transportation shared computer facilities and computer networks i e the internet either use or will use some form of tod pricing however tod rates do not ensure a movement towards economic efficiency unless the patterns of tod substitution are known the model presented here provedes a method for estimating tod substitution without the need for rate experiments that have proven to be both costly and limited by sample selection bias problems this model employs the estimated second moment of demand to estimate a matrix of relative own and cross price elasticities and it can estimate elasticities even when there is no apparent tod price variation the low level of computations required for the estimates allows the application of a bootstrap procedure to estimate the covariance matrix of the elasticities two applications of this model are presented a case of a

liquidity traps and expectation dynamics fiscal stimulus or fiscal austerity we examine global dynamics under infinite horizon learning in new keynesian models where the interest rate rule is subject to the zero lower bound as in evans guse and honkapohja 2008 the intended steady state is locally but not globally stable unstable deflationary paths emerge after large pessimistic shocks to expectations for large expectation shocks that push interest rates to the zero bound a temporary fiscal stimulus or a policy of fiscal austerity appropriately tailored in magnitude and duration will insulate the economy from deflation traps however fiscal switching rules that automatically kick in without discretionary fine tuning can be equally effective

tax evasion and the marginal cost of public funds tax evasion and deadweight loss have similar implications for the rules of public finance the optimal mix of taxes can be derived from the minimization of the sum of aggregate deadweight loss and aggregate cost of tax evasion similarly the marginal cost of public funds includes allowances for marginal deadweight loss and marginal cost of tax evasion per dollar of public revenue acquired

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

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

an economic theory of the second moments of disturbances of behavioral equations applied econometricians have known for a long time that the smooth curves in economics texts which pretend to be the geometric representations of behavioral equations present an over simplified picture of the real world it almost never occurs that data fit a simple theoretical relation exactly and an explicit method of interpreting and handling the deviations from such relations is therefore needed in the early days of econometrics it was frequently assumed that observational errors were the only or at least the main cause of the occurrence of deviations but this idea was later rejected on the ground that even when the data are perfect deviations will continue to be found because there are very few economic agents who react exactly according to some simple mathematical law the neglected factors entered into the picture their combined influence came to be regarded as a random disturbance with zero mean and unknown variance

comment on a probability based stress test of federal reserve assets and income by jens h e christensen jose a lopez and glenn d rudebusch

potential cost synergies from banks acquiring real estate brokerage services abstract national banks and financial holding companies fhc solicited permission from the federal reserve board and the treasury department to add real estate brokerage and management services to list of permissible business activities under the 1999 gramm leach bliley act glb to date permission has been denied due to the community choice in real estate act hr 111 and s 98 this study offers a method of combining the financial data of two independent industries additionally this study identifies the scale returns and cost complementarities that may occur if banks offered real estate brokerage services under a single organization considerable evidence suggests that joining bank and real estate activities under a single organization would continue to generate increasing returns to scale for banks even when large levels of real estate brokerage services are offered by the joint institution in addition the results indicate evidence that bank acquisitions of real estate brokerages do create some cost saving synergies from cost complementarities between product lines finally complementarities exist between traditional bank services and real estate services most at low levels of real estate outputs

liquidity traps learning and stagnation we examine global economic dynamics under learning in a new keynesian model in which the interest rate rule is subject to the zero lower bound under normal monetary and fiscal policy the intended steady state is locally but not globally stable large pessimistic shocks to expectations can lead to deflationary spirals with falling prices and falling output to avoid this outcome we recommend augmenting normal policies with aggressive monetary and fiscal policy that guarantee a lower bound on inflation in contrast policies geared toward ensuring an output lower bound are insufficient for avoiding deflationary spirals

monetary rewards and decision cost in experimental economics a survey of thirty one experimental studies which report data on the comparative effects of monetary rewards and opportunity cost shows 1 several studies in which increased rewards shift the central tendency of the data toward the predictions of rational models 2 in virtually all cases rewards reduce the variance of the data around the predicted outcome this is consistent with a model in which rewards are balanced against decision cost in agent behavior and explicates the argument that when rational models fail it can be attributed to low opportunity cost of deviations from the rational prediction

extensive margins and the demand for money at low interest rates we argue that the relevant monetary decision for the majority of u s households is not the fraction of assets to be held in interest bearing form but whether to hold any such assets at all we call this the decision to adopt the financial technology we show that the key variable governing the adoption decision is the product of the interest rate times the total amount of assets this implies that the interest elasticity of household money demand at low interest rates can be estimated from the variation in asset holdings in a cross section of households rather than historical interest rate variations we do so with the 1989 survey of consumer finances we find that a the elasticity of money demand is very small when the interest rate is small b the probability that a household holds any amount of interest bearing assets is positively related to the level of financial assets and c the cost of adopting financial technologies is negatively related to participation in a pension program at intere

the mystique surrounding the central bank s balance sheet applied to the european crisis abstract a central bank s resource constraint bounds the dividends it can distribute by the present value of seignorage which is a modest share of gdp this is in spite of the mystique behind a central bank s balance sheet moreover the statutes of the federal reserve or the ecb make it difficult for it to redistribute resources across regions in a simple model of sovereign default where multiple equilibria arise if debt repudiation lowers fiscal surpluses the central bank may help to select one equilibrium the central bank s main lever over fundamentals is to raise inflation but otherwise the balance sheet gives it little leeway

the size of government most research on the causes of growth in government expenditure has focused on the demand for government services in this paper we argue that in fact this growth may have occurred because of changes in supply changes in technology leading to increased specialization and thus increased opportunity costs of self production have led to increased market production and increased record keeping also female labor force participation has increased both of these factors serve to reduce the efficiency cost of collecting taxes if the demand for government spending has not changed this increase in supply would lead to a larger public sector we estimate a system of simultaneous equations for the period 1929 1970 incorporating this hypothesis and the results are consistent with the theory we are able to explain virtually all of the growth of government increases in female labor force participation seems to be a very important variable in this explanation

fiscal requirements for price stability maintaining price stability requires not only commitment to an appropriate monetary policy rule but an appropriate scal policy rule as well ricardian equivalence does not imply that scal policy is irrelevant except in the case of a certain class of policies ricardian policies the role of scal developments in inflation determination under a non ricardian regime is illustrated through an analysis of the bond price support regime of the 1940s a monetary scal regime with attractive properties would combine a taylor rule for monetary policy with nominal decit targeting as a scal policy commitment

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

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

exit strategies for monetary policy abstract in response to the financial crisis of 2007 08 all major central banks decreased interest rates to historically low levels and created large excess reserves central bankers and academics currently discuss how to implement monetary policy going forward we find that paying interest on reserves ior is optimal if the central bank has full fiscal support if the central bank has no fiscal support reducing reserves is optimal this can be achieved by reserve absorbing operations which hold the size of the balance sheet constant or by selling assets which reduces the size of the balance sheet

the mystery of the printing press monetary policy and self fulfilling debt crises we study the mechanism by which unconventional balance sheet monetary policy can rule out self fulfilling sovereign default in a model with optimizing but discretionary fiscal and monetary policymakers by purchasing sovereign debt the central bank e ectively swaps risky government paper for monetary liabilities only exposed to inflation risk thus yielding a lower interest rate we characterize a critical threshold for central bank purchases beyond which absent fundamental fiscal stress the government strictly prefers primary surplus adjustment to default since default may still occur for fundamental reasons however the central bank faces the risk of losses on sovereign debt holdings which may generate ine cient inflation this risk does not undermine the credibility of a backstop nor the ability of a central bank to pursue its inflation objectives when the latter enjoys fiscal backing or fiscal authorities are su ciently averse to inflation

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

currency composition of foreign exchange reserves abstract this paper analyses the factors that govern the choice of the currency composition of official foreign exchange reserves first we introduce a new panel dataset on the key currencies in foreign exchange reserves of about 60 economies in the 1999 2017 period second we show that the currency composition of reserves relates strongly to the co movement of the domestic currency with key currencies and the currency invoicing of trade these factors represent attributes of the dollar or the euro rather than of the united states or the euro area they exert about equal effects on the currency composition of foreign exchange reserves we demonstrate that these findings are robust to a host of other possible factors

linear and quadratic spline models for consumer demand functions this paper combines flexible functional form techniques which provide local approximations to indirect preferenc es with respect to prices and incomes with spline techniques that provide global approximations with respect to real income the main technical problem is that real income or utility is an unobserved variable starting with the normalized quadratic expenditure functio n linear and quadratic spline models are introduced theoretically and are empirically estimated using japanese consumer data for four goods fo r the years 1970 87 the semi nonparametric literature initiated by a r gallant is reviewed and a limited semi nonparametric property is claimed to hold for the spline models presented in the paper

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

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

measuring consumption efficiency with utility theory and stochastic frontier analysis the concept of production efficiency has been studied since the 1960s but consumption activity as well may be inefficient for various reasons such as product complexity lack of information the bounded rationality of the consumer and imperfect markets to name a few this study proposes a conceptual framework for measuring the consumption efficiency of differentiated products based on traditional utility theory it employs stochastic frontier analysis sfa in an empirical analysis it makes use of hedonic price theory to link traditional utility theory and the sfa framework when the developed model is applied to the korean personal computer market empirical results indicate the levels and distribution of consumption efficiency in that market the findings afford us a better understanding of the characteristics of the innovation process in that market

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

estimation of a hedonic price equation for burgundy wine a hedonic price equation and two jury grade equations are estimated for burgundy wine the approach is the same as in an earlier bordeaux wine paper combris et al 1997 the data come from an experimental study that is very similar to the study on bordeaux wines the results for the two wine growing regions are compared and discussed

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

input demands and inefficiency in u s agriculture markov chain monte carlo mcmc methods are used to estimate a seemingly unrelated regression sur system of input demand functions for u s agriculture our demand functions have flexible forms and allow for nonrandom technical inefficiency concavity constraints are imposed at individual data points and the distributions of measures of relative technical efficiency are constrained to the unit interval results are evaluated in terms of characteristics of the posterior distributions of parameters measures of relative technical efficiency and other nonlinear functions of the parameters

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

perils of unconventional monetary policy abstract unconventional monetary policy by relaxing restrictions on the composition of the balance sheet of the central bank compromises control over the stochastic path of inflation or in open economies over the stochastic path of exchange rates if the composition of the balance sheet is unrestricted then the path of inflation is indeterminate this is the case under pure quantitative easing where the target is the size of real money balances in contrast credit easing policies restrict the composition of the portfolio by targeting a specific expansion in the maturity profile of bonds bought and thus can implement a determinate path of inflation the composition of the portfolios traded by monetary fiscal authorities also determines premia in asset and currency markets

reverse speculative attacks abstract in january 2015 in the face of sustained capital inflows the swiss national bank abandoned the floor for the swiss franc against the euro a decision which led to the appreciation of the swiss franc the objective of this paper is to present a simple numerical framework that helps to better understand the timing of this episode which we label a reverse speculative attack we model a central bank which wishes to maintain a peg and responds to increases in demand for domestic currency by expanding its balance sheet in contrast to the classic speculative attacks which are triggered by the depletion of foreign assets reverse attacks are triggered by the concern of future balance sheet losses our key result is that the interaction between the desire to maintain the peg and the concern about future losses can lead the central bank to first accumulate a large amount of reserves and then to abandon the peg just as we have observed in the swiss case

the effectiveness of the ecb s unconventional monetary policy comparative evidence from crisis and non crisis euro area countries abstract during the european financial crisis the european central bank implemented a series of unconventional monetary policy measures we argue that these programs lowered the bond yield spreads of euro area countries this hypothesis is tested using pooled ols estimations and two different datasets monetary policy event dummies and the purchase volumes of the securities markets programme smp overall we find significantly negative effects on bond yield spreads for both datasets leading us to accept the hypothesis while the omt reduces the spreads of both crisis and non crisis countries ltros and the lowering of the deposit rate to 0 percent are mainly effective in non crisis countries the smp lowers the spreads of crisis countries but it has the opposite effect on non crisis countries this converse effect is explained by the risk that increasingly accumulates on the ecb s balance sheet through the smp and that way constitutes a fiscal risk for non crisis countries the results are confirmed by pooled ols estimations that measure the effect of unconventional monetary policy on central government debt

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

what is wrong with taylor rules using judgment in monetary policy through targeting rules it is argued that inflation targeting is best understood as a commitment to a targeting rule rather than an instrument rule e ither ageneral targeting rule explicit objectives for monetary policy or a specific targeting rule a criterion for the forecasts of the target variables to be fulfilled essentially the equality of the marginal rates of transformation and substitution between the target variables targeting rules allow the use of judgment and extramodel information are more robust and easier to verify than optimal instrument rules and they can nevertheless bring the economy close to the socially optimal equilibrium

estimating technical efficiency of australian dairy farms using alternative frontier methodologies technical efficiency is estimated and examined for a cross section of australian dairy farms using various frontier methodologies bayesian and classical stochastic frontiers and data envelopment analysis the results indicate technical inefficiency is present in the sample data also identified are statistical differences between the point estimates of technical efficiency generated by the various methodologies however the rank of farm level technical efficiency is statistically invariant to the estimation technique employed finally when confidence credible intervals of technical efficiency are compared significant overlap is found for many of the farms intervals for all frontier methods employed the results indicate that the choice of estimation methodology may matter but the explanatory power of all frontier methods is significantly weaker when interval estimate of technical efficiency is examined

on the fit of new keynesian models this article provides new tools for the evaluation of dynamic stochastic general equilibrium dsge models and applies them to a large scale new keynesian model we approximate the dsge model by a vector autoregression and then systematically relax the implied cross equation restrictions and document how the model fit changes we also compare the dsge model s impulse responses to structural shocks with those obtained after relaxing its restrictions we find that the degree of misspecification in this large scale dsge model is no longer so large as to prevent its use in day to day policy analysis yet is not small enough to be ignored

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

trending economic factors and the structure of congress in the growth of government 1930 2002 we investigate the role of congress in the growth of federal public expenditure since 1930 building on the work of kau and rubin public choice 113 389 402 2002 the model incorporates majority party strength and the extent of party control of congress in addition to the median ideological position of elected representatives we first provide estimates of the relative importance of the state of congress and of trending supply and demand side economic factors in the evolution of federal spending the resulting models are then used to simulate the consequences of the radical and historically unprecedented shift to the right of congress in 1994 95

economic efficiency and frontier techniques abstract most of the literature related to the measurement of economic efficiency has based its analysis either on parametric or on non parametric frontier methods the choice of estimation method has been an issue of debate with some researchers preferring the parametric and others the non parametric approach the aim of this paper is to provide a critical and detailed review of both core frontier methods in our opinion no approach is strictly preferable to any other moreover a careful consideration of their main advantages and disadvantages of the data set utilized and of the intrinsic characteristics of the framework under analysis will help us in the correct implementation of these techniques recent developments in frontier techniques and economic efficiency measurement such as bayesian techniques bootstrapping duality theory and the analysis of sampling asymptotic properties are also considered in this paper

bayesian efficiency analysis with a flexible form the aim cost function in this article we describe the use of gibbs sampling methods for drawing posterior inferences in a cost frontier model with an asymptotically ideal price aggregator nonconstant returns to scale and composed error an empirical example illustrates the sensitivity of efficiency measures to assumptions made about the functional form of the frontier we also examine the consequences of imposing regularity through parametric restrictions alone

risk endogeneity at the lender investor of last resort abstract to what extent can a central bank influence its own balance sheet credit risks during a financial crisis through unconventional monetary policy operations to study this question we develop a risk measurement framework to infer the time variation in portfolio credit risks at a high weekly frequency focusing on the eurosystem s experience during the euro area sovereign debt crisis between 2010 and 2012 we find that the announcement and implementation of unconventional monetary policy operations generated beneficial risk spill overs across policy portfolios this caused overall risk to be nonlinear in exposures in some instances the eurosystem reduced its overall balance sheet credit risk by doing more in line with bagehot s well known assertion that occasionally only the brave plan is the safe plan
