monetary fiscal policy interactions and indeterminacy in postwar us data using a micro founded model and a likelihood based inference method we address three questions in this article first what monetary and fiscal policy regimes characterized postwar us data second was equilibrium indeterminacy a feature of the economy before paul volcker s chairmanship at the federal reserve third what were the effects of shifts in monetary and fiscal policy on the aggregate economy we find that pre volcker a passive monetary and fiscal policy regime prevailed while postvolcker an active monetary and passive fiscal policy regime characterized the economy 1 since both monetary and fiscal policies were passive pre volcker there was equilibrium indeterminacy moreover the effects of monetary and fiscal policy shifts on the aggregate economy were substantially different in the two time periods for example while pre volcker an unanticipated increase in interest rates led to an increase in output and inflation post volcker it led to a decrease in output and inflation moreover while pre volcker an unanticipated increase in the lump sum tax revenues to output ratio led to a decline in output and inflation post volcker it had no effects on output or inflation the response of the economy pre volcker was thus similar to that predicted by the fiscal

a multi objective multi period stochastic programming model for public debt management while raising debt on behalf of the government public debt managers need to consider several possibly conflicting objectives and have to find an appropriate combination for government debt taking into account the uncertainty with regard to the future state of the economy in this paper we explicitly consider the underlying uncertainties with a complex multi period stochastic programming model that captures the trade offs between the objectives the model is designed to aid the decision makers in formulating the debt issuance strategy we apply an interactive procedure that guides the issuer to identify good strategies and demonstrate this approach for the public debt management problem of turkey

surplus debt regressions abstract single equation estimates of fiscal reaction functions which relate primary surpluses to past debt gdp ratios and control variables are subject to potentially serious simultaneity bias that can produce misleading inferences about fiscal behavior biases arise from failure to model the general equilibrium relationships between government debt and surpluses relationships that bring in the forward looking nature of nominal debt valuation and the role of monetary policy in that valuation

international evidence on fiscal solvency is fiscal policy responsible abstract we conduct a cross country empirical analysis of fiscal solvency based on dynamic stochastic general equilibrium conditions the results show evidence of fiscal solvency in the form of a robust positive conditional response of the primary balance to changes in public debt in panels for emerging and industrial economies and in a combined panel emerging economies show a stronger response and hence converge to lower mean debt output ratios as observed in the data the results are weaker for countries with debt ratios exceeding panel means and medians hence we can separate countries where fiscal solvency holds from those where it remains in doubt

risk neutral firms can extract unbounded profits from consumers with prospect theory preferences this paper considers the problem of a risk neutral firm offering a gamble to consumers with preferences given by prospect theory under conditions satisfied by virtually all functional forms used in the literature firms can extract arbitrarily high expected values from consumers moreover for any given lottery there exists another lottery that makes both the firm and the consumer better off as a consequence equilibria and pareto optimal allocations do not exist in standard monopolistic or competitive models

dissecting fiscal multipliers under the fiscal theory of the price level abstract we derive analytical expressions for fiscal multipliers on output and inflation under the fiscal theory of the price level in the associated fiscal regime taxation multipliers turn positive while the government spending multiplier has the same functional form as its counterpart in the monetary regime augmented by a nominal wealth effect as a result fiscal multipliers tend to be larger in the fiscal regime with the degree of price stickiness being a key determinant of their exact sizes in particular multipliers go to infinity as prices become fully fixed and collapse to their equivalents in the monetary regime as prices become fully flexible standard calibrations suggest that the fiscal regime hosts a government spending multiplier on output that lies between 1 and 3 we also analyze the effectiveness of money financed fiscal stimulus in the fiscal regime money financed stimulus is equivalent to a particular form of debt financed stimulus the effectiveness of money financed stimulus in raising output relative to inflation decreases as monetary policy becomes more responsive to inflation

evolving monetary fiscal policy mix in the united states a micro founded model that allows for changes in the monetary fiscal policy mix and in the volatility of structural shocks is fit to us post wwii data agents are aware of the possibility of regime changes and their beliefs have an impact on the law of motion of the macroeconomy the results show that the 60s and the 70s were characterized by a prolonged period of active fiscal policy and passive monetary policy the appointment of volcker marked a change in the conduct of monetary policy but it took almost ten years for the fiscal authority to start accommodating this regime change

interpreting the macroeconomic time series facts the effects of monetary policy existing theory and evidence on the effects of monetary policy are reviewed substantial room for disagreement among economists remains new evidence based on multivariate time series studies of several countries is presented while certain patterns in the data consistent with effective monetary policy are strikingly similar across countries others particularly the tendency of interest rate increases to predict high inflation are harder to reconcile with effective monetary policy

the role of inflation target adjustment in stabilization policy we study optimal monetary policy in a new keynesian model in which the monetary authority faces a trade off between inflation and output gap stabilization due to cost push shocks in particular we highlight the role of the inflation target adjustment in stabilization policy by showing that it can mitigate this policy trade off and considerably improve welfare the main findings can be summarized as follows first we find that the welfare cost of a standard taylor rule is non trivial even with optimized policy coefficients second we propose an additional policy tool of a medium run inflation target mrit rule when combined with the standard taylor rule the optimal mrit significantly reduces fluctuations in inflation originating from the cost push shocks and results in a similar level of welfare to that associated with the ramsey optimal policy third the optimal mrit needs to be adjusted in a persistent manner and in the opposite direction to the realization of a cost push shock fourth the welfare implication of the mrit is more pronounced under a flatter phillips curve finally the main findings are relevant to the current economic environment of low inflation rates under a flat phillips curve implying that the monetary authority should increase the inflation target in such an environment

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

monetary fiscal policy interaction and fiscal inflation a tale of three countries abstract we study the impact of the interaction between fiscal and monetary policy on the low frequency relationship between the fiscal stance and inflation using cross country data from 1965 to 1999 in a first step we contrast the monetary fiscal narrative for germany the u s and italy with evidence obtained from simple regression models and a time varying var we find that the low frequency relationship between the fiscal stance and inflation is low during periods of an independent central bank and responsible fiscal policy and more pronounced in times of non responsible fiscal policy and accommodative monetary authorities in a second step we use an estimated dsge model to interpret the low frequency measure structurally and to illustrate the mechanisms through which fiscal actions affect inflation in the long run the findings from the dsge model suggest that switches in the monetary fiscal policy interaction and accompanying variations in the propagation of structural shocks can well account for changes in the low frequency relationship between the fiscal stance and inflation

monetary and fiscal policy interactions in the post war u s abstract a new keynesian model allowing for an active monetary and passive fiscal policy ampf regime and a passive monetary and active fiscal policy pmaf regime is estimated to fit various u s samples from 1955 to 2007 the results show that data in the pre volcker periods strongly prefer an ampf regime even with a prior centered in the pmaf region the estimation however is not very informative about whether the federal reserve s reaction to inflation is greater than one in the pre volcker period because much lower values can still preserve determinacy under passive fiscal policy in addition whether a pmaf regime can generate consumption growth following a government spending increase depends on the degree of price stickiness an income tax cut can yield an unusual negative labor response if monetary policy aggressively stabilizes output growth

monetary policy trend inflation and the great moderation an alternative interpretation with positive trend inflation the taylor principle does not guarantee a determinate equilibrium we provide new theoretical results on determinacy in new keynesian models with positive trend inflation and new empirical findings on the federal reserve s reaction function before and after the volcker disinflation to find that i while the fed likely satisfied the taylor principle before volcker the us economy was still subject to self fulfilling fluctuations in the 1970s ii the us economy switched to determinacy during the volcker disinflation and iii the switch reflected changes in the fed s response to macroeconomic variables and the decline in trend inflation jel e12 e23 e31 e32 e52

the cyclical behavior of marginal cost and price the author examines the cyclical behavior of price marginal cost margins for u s manufac turing after 1956 short run marginal cost is markedly procyclical this is primarily due to procyclical overtime payments incurred beca use employment is not perfectly flexible in most industries output price fails to respond to the cyclical movement in marginal cost so price marginal cost margins are markedly countercyclical the res ults contradict business cycle theories that explain low production i n a recession by a high real cost of producing they support theories that explain low production in a recession by the inability of firms to sell their output copyright 1987 by american economic association

u s monetary regimes and optimal monetary policy in the euro area monetary policy in the united states has been documented to have switched from reacting weakly to inflation fluctuations during the 1970s to fighting inflation aggressively from the early 1980s onward in this paper i analyze the impact of the u s monetary policy regime switches on the eurozone i construct a new keynesian two country model where foreign u s monetary policy switches regimes over time i estimate the model for the u s and the euro area using quarterly data and find that the united states has switched between those two regimes in line with existing evidence i show that foreign regime switches affect home eurozone inflation and output volatility and their responses to shocks substantially as long as the home central bank commits to a time invariant interest rate rule reacting to domestic conditions only optimal policy in the home country instead requires that the home central bank reacts strongly to domestic producer price inflation and to international variables such as imported goods relative prices in fact i show that currency misalignments and relative prices play a crucial role in the transmission of foreign monetary policy regime switches internationally interestingly i show that only marginal gains arise for the euro area when the european central bank ecb adjusts its policy according to the monetary regime in the united states thus a simple time invariant monetary policy rule with a strong reaction to producer price index ppi inflation and relative prices is enough to counteract the effects of monetary policy switches in the united states

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

monetary policy rules and macroeconomic stability some new evidence in a seminal paper richard clarida jordi gall and mark gertler 2000 studied the implica tions of monetary policy for macroeconomic fluctuations using a prototypical forward looking sticky price model of the monetary transmission mechanism they proposed simple forward looking equations for the reaction function of monetary policy to deviations of inflation and output from their implicit targets they estimated these equations over sample periods before and after paul volcker became chairman of the fed they found that the policy rate did not react sufficiently strongly to expected deviations of inflation from target prior to volcker thus violat ing the taylor principle and opening up the possibility of sunspot fluctuations induced by self fulfilling expectations in contrast policy over the volcker greenspan era was found to satisfy the taylor principle and this was seen as an important factor contributing to the conquest of us inflation 1

why does private consumption rise after a government spending shock recent empirical evidence suggests that private consumption is crowded in by government spending this outcome violates existing macroeconomic theory according to which the negative wealth effect brought about by a rise in public expenditure should decrease consumption

identifying fiscal inflation abstract fiscal theorists warn about the risk of future inflation as a consequence of fiscal imbalances in the us because actual inflation remains historically low and data on inflation expectations do not corroborate such risks warnings for fiscal inflation are often ignored in policy and academic circles this paper shows that a canonical nk dsge model enables identifying an anticipated component of inflation expectations that is closely related to fiscal policy estimation results suggest that fiscal inflation concerns have induced a 1 6 points increase in long run inflation since 2001 the model also rationalizes why data on inflation expectations do not reveal such concerns outright

monetary policy inflation expectations and the price puzzle this article re examines the var evidence on the price puzzle and proposes a new theoretical interpretation using actual data and two identification strategies based on zero restrictions and model consistent sign restrictions we find that the positive response of prices to a monetary policy shock is historically limited to the sub samples that are typically associated with a weak interest rate response to inflation using pseudo data generated by a sticky price model of the us economy we then show that the structural vars are capable of reproducing the price puzzle only when monetary policy is passive the omission in the vars of a variable capturing expected inflation is found to account for the price puzzle observed in simulated and actual data structural vector autoregressions svars are widely used for measuring and understanding the effects of monetary policy innovations on the aggregate economy while most results in the var literature are consistent with economic intuition and macroeconomic theory the typically found positive and significant reaction of the price level on impact to a monetary policy shock is a fact that most monetary models

investigating inflation persistence across monetary regimes under inflation targeting estimates of the indexation parameter in hybrid new keynesian phillips curves are either equal to zero or very low in the united kingdom canada sweden and new zealand analogous results hold for the euro area under the european monetary union and for switzerland under the new monetary regime under stable regimes with clearly defined nominal anchors inflation appears to be purely forward looking these results question the notion that the intrinsic inflation persistence found in post wwii u s data is structural in the sense of lucas carnegie rochester conference series on public policy 1 1976 19 46 and suggest that hardwiring inflation persistence in macroeconomic models is potentially misleading

e stability vis a vis determinacy in regime switching models abstract this paper examines e stability determinacy and indeterminacy in a general class of regime switching models with lagged endogenous variables using determinacy conditions from cho 2016 2020 our first result extends mccallum 2007 to models with time varying parameters the unique mean square stable equilibrium is e stable if agents have current information and one period ahead decision rules further we address the existence of e stable non fundamental equilibria and find that iteratively e stable equilibria of indeterminate switching models can exist finally we show that indeterminate new keynesian models with persistent recurring interest rate peg regimes admit iteratively e stable equilibria in special cases the iterative e stability condition coincides with the long run taylor principle

individual preferences monetary gambles and stock market participation a case for narrow framing we argue that narrow framing whereby an agent who is offered a new gamble evaluates that gamble in isolation may be a more important feature of decision making than previously realized our starting point is the evidence that people are often averse to a small independent gamble even when the gamble is actuarially favorable we find that a surprisingly wide range of utility functions including many nonexpected utility specifications have trouble explaining this evidence but that this difficulty can be overcome by allowing for narrow framing our analysis makes predictions as to what kinds of preferences can most easily address the stock market participation puzzle

monetary fiscal policy interactions and fiscal stimulus abstract increases in government spending trigger substitution effects both inter and intra temporal and a wealth effect the ultimate impacts on the economy hinge on current and expected monetary and fiscal policy behavior studies that impose active monetary policy and passive fiscal policy typically find that government consumption crowds out private consumption higher future taxes create a strong negative wealth effect while the active monetary response increases the real interest rate this paper estimates markov switching policy rules for the united states and finds that monetary and fiscal policies fluctuate between active and passive behavior when the estimated joint policy process is imposed on a conventional new keynesian model government spending generates positive consumption multipliers in some policy regimes and in simulated data in which all policy regimes are realized the paper reports the model s predictions of the macroeconomic impacts of the american recovery and reinvestment act s implied path for government spending under alternative monetary fiscal policy combinations

controlling inflation with timid monetary fiscal regime changes can monetary policy control inflation when both monetary and fiscal policies change over time when monetary policy is active a long run fiscal principle entails flexibility in fiscal policy that preserves determinacy even when deviating from passive fiscal substantially for brief periods or timidly for prolonged periods in order to guarantee a unique equilibrium monetary and fiscal policies must coordinate not only within but also across regimes and not simply on being active or passive but also on their extent the amplitude of deviations from the active monetary passive fiscal benchmark determines whether a regime is ricardian timid deviations do not imply wealth effects

stepping on a rake the role of fiscal policy in the inflation of the 1970s abstract the inflation of the 1970s in the us is often discussed as if the only type of policy action that could have prevented the inflation were monetary policy actions and the only type of policy errors that might have induced the inflation were monetary policy errors yet fiscal policy underwent dramatic shifts in the 1970s and economic theory makes clear that in an environment of uncertainty about future fiscal policy monetary policy instruments may lose potency or have perverse effects this paper documents the vagaries of fiscal policy in this period and argues that people at the time must have been uncertain about fiscal policy s future course it also lays out a theoretical framework for understanding the effects of fiscal uncertainties on monetary policy and shows that fiscal variables have predictive value in dynamic models even if traditional monetary policy indicators are included in the system

formulation of the russell yasuda kasai financial planning model this paper describes the formulation of the russell yasuda kasai financial planning model including the motivation for the model the presentation complements the discussion of the technical details of the financial modeling process and the managerial impact of its use to help allocate the firm s assets over time discussed in carin o et al 1994 1998 respectively the multistage stochastic linear program incorporates yasuda kasai s asset and liability mix over a five year horizon followed by an infinite horizon steady state end effects period the objective is to maximize expected long run profits less expected penalty costs from constraint violations over the infinite horizon scenarios are used to represent the uncertain parameter distributions the constraints represent the institutional cash flow legal tax and other limitations on the asset and liability mix over time

a multistage linear stochastic programming model for optimal corporate debt management abstract large corporations fund their capital and operational expenses by issuing bonds with a variety of indexations denominations maturities and amortization schedules we propose a multistage linear stochastic programming model that optimizes bond issuance by minimizing the mean funding cost while keeping leverage under control and insolvency risk at an acceptable level the funding requirements are determined by a fixed investment schedule with uncertain cash flows candidate bonds are described in a detailed and realistic manner a specific scenario tree structure guarantees computational tractability even for long horizon problems based on a simplified example we present a sensitivity analysis of the first stage solution and the stochastic efficient frontier of the mean risk trade off a realistic exercise stresses the importance of controlling leverage based on the proposed model a financial planning tool has been implemented and deployed for brazilian oil company petrobras

high trend inflation and passive monetary detours abstract does the long run taylor principle davig and leeper 2007 hold when both monetary and fiscal policies can switch and there is positive trend inflation we find that with high trend inflation passive monetary detours are no longer possible whatever fiscal policy is in place this has important policy implications in terms of flexibility and monetary fiscal authorities coordination

changes in the federal reserve s inflation target causes and consequences this paper estimates a new keynesian model to draw inferences about the behavior of the federal reserve s unobserved inflation target the results indicate that the target rose from 1 1 4 percent in 1959 to over 8 percent in the mid to late 1970s before falling back below 2 1 2 percent in 2004 the results also provide some support for the hypothesis that over the entire postwar period federal reserve policy has systematically translated short run price pressures set off by supply side shocks into more persistent movements in inflation itself although considerable uncertainty remains about the true source of shifts in the inflation target jel e31 e32 e52

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

investment shocks and business cycles abstract the origins of business cycles are still controversial among macroeconomists this paper contributes to this debate by studying the driving forces of fluctuations in an estimated new neoclassical synthesis model of the u s economy in this model most of the variability of output and hours at business cycle frequencies is due to shocks to the marginal efficiency of investment imperfect competition and to a lesser extent technological frictions are the key to their transmission although labor supply shocks explain a large fraction of the fluctuations in hours at very low frequencies they are irrelevant over the business cycle this finding is important because the microfoundations of these disturbances are widely regarded as unappealing

mean variance asset liability management cointegrated assets and insurance liability abstract the cointegration of major financial markets around the globe is well evidenced with strong empirical support this paper considers the continuous time mean variance mv asset liability management alm problem for an insurer investing in an incomplete financial market with cointegrated assets the number of trading assets is allowed to be less than the number of brownian motions spanning the market the insurer also faces the risk of paying uncertain insurance claims during the investment period we assume that the cointegration market follows the diffusion limit of the error correction model for cointegrated time series using the markowitz 1952 mv portfolio criterion we consider the insurer s problem of minimizing variance in the terminal wealth given an expected terminal wealth subject to interim random liability payments following a compound poisson process we generalize the technique developed by lim 2005 to tackle this problem the particular structure of cointegration enables us to solve the alm problem completely in the sense that the solutions of the continuous time portfolio policy and efficient frontier are obtained as explicit and closed form formulas

the time varying volatility of macroeconomic fluctuations we investigate the sources of the important shifts in the volatility of us mac roeconomic variables in the postwar period to this end we propose the esti mation of dsge models allowing for time variation in the volatility of the structural innovations we apply our estimation strategy to a large scale model of the business cycle and find that shocks specific to the equilibrium condition of investment account for most of the sharp decline in volatility of the last two decades jel c51 e32

on fiscal multipliers estimates from a medium scale dsge model this paper contributes to the debate on fiscal multipliers in the context of a structural model i estimate a micro founded dynamic stochastic general equilibrium model that features a rich fiscal policy block and a transmission mechanism for government spending shocks using bayesian techniques for us data

fiscal consolidations and heterogeneous expectations abstract we analyze fiscal consolidations using a new keynesian model where agents have heterogeneous expectations and are uncertain about the composition of consolidations we look at spending based and tax based consolidations and analyze their effects separately we find that the effects of consolidations and the output multipliers are sensitive to heterogeneity in expectations before and after implementation of a specific fiscal plan depending on the beliefs about the type of consolidation prior to implementation we show that heterogeneity in expectations may lead to optimism in the economy improving thus the performance of a specific fiscal plan or can work towards the opposite direction leading to pessimism amplifying the contractionary effects of the consolidation in general we find that spending based consolidations last longer and lead to deeper recessions when agents are boundedly rational compared to the rational expectations benchmark while the opposite holds for tax based consolidations

indexing the income tax code monetary fiscal interaction and the great moderation abstract this paper considers the consequences of automatically indexing the us federal income tax code to inflation indexation implemented during the 1981 federal tax overhaul and active monetary policy constitute necessary conditions for a unique rational expectations equilibrium in standard new keynesian models with a generalized progressive labor income tax additionally fixing the monetary regime shows that indexation reduces overall volatility in the model as well as the contribution of supply side disturbances together these results support a fiscal extension to the good policy hypothesis of the great moderation and encourage further indexation of the united states tax code

measuring prior sensitivity and prior informativeness in large bayesian models abstract in large bayesian models such as modern dsge models it is difficult to assess how much the prior affects the results this paper derives measures of prior sensitivity and prior informativeness that account for the high dimensional interaction between prior and likelihood information the basis for both measures is the derivative matrix of the posterior mean with respect to the prior mean which is easily obtained from markov chain monte carlo output we illustrate the approach by examining posterior results in the small model of lubik and schorfheide 2004 and the large model of smets and wouters 2007

time consistency and risk averse dynamic decision models definition interpretation and practical consequences abstract this paper aims at resolving a major obstacle to practical usage of time consistent risk averse decision models the recursive objective function generally used to ensure time consistency is complex and has no clear direct interpretation practitioners rather choose a simpler and more intuitive formulation even though it may lead to a time inconsistent policy based on rigorous mathematical foundations we impel practical usage of time consistent models as we provide practitioners with an intuitive economic interpretation for the referred recursive objective function we also discourage time inconsistent models by arguing that the associated policies are sub optimal we developed a new methodology to compute the sub optimality gap associated with a time inconsistent policy providing practitioners with an objective method to quantify practical consequences of time inconsistency our results hold for a quite general class of problems and we choose without loss of generality a cvar based portfolio selection application to illustrate the developed concepts

asset market participation monetary policy rules and the great inflation this paper argues that limited asset market participation is crucial in explaining u s macroeconomic performance and monetary policy before the 1980s and their changes thereafter in an otherwise conventional sticky price model standard aggregate demand logic is inverted at low enough asset market participation interest rate increases become expansionary passive monetary policy ensures equilibrium determinacy and maximizes welfare this suggests that federal reserve policy in the pre volcker era was better than conventional wisdom implies we provide empirical evidence consistent with this hypothesis and study the relative merits of changes in structure and shocks for reproducing the conquest of the great inflation and the great moderation

solving and estimating indeterminate dsge models we propose a method for solving and estimating linear rational expectations models that exhibit indeterminacy and we provide step by step guidelines for implementing this method in the matlab based packages dynare and gensys our method redefines a subset of expectational errors as new fundamentals this redefinition allows us to treat indeterminate models as determinate and to apply standard solution algorithms we prove that our method is equivalent to the solution method proposed by lubik and schorfheide 2003 2004 and using the new keynesian model described in lubik and schorfheide 2004 we demonstrate how to apply our theoretical results with a practical exercise

regime switches agents beliefs and post world war ii u s macroeconomic dynamics the evolution of inflation and output over the last 50 years is examined through the lens of a micro founded model that allows for changes in the behavior of the federal reserve and in the volatility of structural shocks agents are aware of the possibility of regime changes and their beliefs have an impact on the law of motion underlying the macroeconomy the results support the view that there were regime switches in the conduct of monetary policy however the behavior of the federal reserve is identified by repeated fluctuations between a hawk and a dove regime instead of by the traditional pre and post volcker structure counterfactual simulations show that if agents had anticipated the appointment of an extremely conservative chairman inflation would not have reached the peaks of the late 70s and the inflation output trade off would have been less severe these beliefs counterfactuals are new in the literature finally the paper provides a bayesian algorithm to handle the technical difficulties that arise in a rational expectations model with markov switching regimes

indeterminacy change points and the price puzzle in an estimated dsge model abstract we extend lubik and schorfheide s 2004 testing for indeterminacy an application to u s monetary policy american economic review 94 190 217 likelihood based estimation of dynamic stochastic general equilibrium dsge models under indeterminacy to encompass a sample period the includes both determinacy and indeterminacy by implementing a change point methodology chib s 1998 estimation and comparison of multiple change point models journal of econometrics 86 221 241 by letting the data provide estimates of the dates of the determinacy regimes and allowing the estimates of structural parameters to be the same across regimes we obtain more precise estimates of the differences in characteristics such as the impulse responses across the regimes the most striking finding about the indeterminacy regime which is estimated to coincide with the great inflation of the 1970s is that it exhibits the price puzzle in that the inflation rate rises immediately and in a sustained manner following a positive interest rate shock thus the price puzzle might have been a genuine phenomenon under indeterminacy rather than a false finding to be excised through specification search and parameter restrictions

self fulfilling expectations and the inflation of the 1970s evidence from the livingston survey abstract using survey data on expectations we examine whether the response of monetary policy to sudden movements in expected inflation contributed to the persistent high inflation of the 1970s the evidence suggests that prior to 1979 the fed accommodated temporary shocks to expected inflation which then led to persistent increases in actual inflation we do not find this behavior in the post 1979 data among commonly cited factors oil and fiscal shocks do not appear to have triggered an increase in expected inflation that eventually resulted in higher actual inflation

the price puzzle reconsidered abstract a large literature has employed structural vector autoregressive svar models to investigate the empirical effects of u s monetary policy many of these models regularly produce a price puzzle a rise in the aggregate price level in response to a contractionary innovation to monetary policy unless commodity prices are included conventional wisdom maintains that commodity prices resolve the price puzzle because they contain information that helps the federal reserve forecast inflation i examine a number of plausible alternative indicator variables and find little correlation between an ability to forecast inflation and an ability to resolve the price puzzle additionally a sub sample investigation reveals that evidence of a price puzzle is associated primarily with the 1959 1979 sample period and that most indicators including commodity prices cannot resolve the puzzle over this period

corporate debt management and the value of the firm three alternative characterizations of corporate debt management policy which have had wide currency in the literature are examined they are shown to give rise to substantial differences in their predictions of total firm value this study concludes that of the three the one that assumes that management periodically rebalances the firm s debt levels in response to evolving new information on expected future operating cash flows is the most logically consistent on that basis a reinterpretation of the available empirical evidence on the tax effect of debt is indicated

until the bitter end on prospect theory in a dynamic context many economic and financial decisions depend crucially on their timing people decide when to invest in a project when to liquidate assets or when to stop gambling in a casino we provide a general result on prospect theory decision makers who are unaware of the time inconsistency induced by probability weighting if a market offers a sufficiently rich set of investment strategies then such naive investors postpone their stopping decisions indefinitely we illustrate the drastic consequences of this never stopping result and conclude that probability distortion in combination with naivete leads to unrealistic predictions for a wide range of dynamic setups

when does government debt crowd out investment summary we examine when government debt crowds out investment for the us economy using an estimated new keynesian model with detailed fiscal specifications and accounting for monetary and fiscal policy interactions whether investment is crowded in or out in the short term depends on policy shocks triggering debt expansions higher debt can crowd in investment for cutting capital tax rates or increasing government investment contrary to the conventional view no systematic relationships between real interest rates and investment exist explaining why reduced form regressions are inconclusive about crowding out at longer horizons distortionary financing is important for the negative investment response to debt copyright 2013 john wiley sons ltd

scenario generation and stochastic programming models for asset liability management in this paper we develop and test scenario generation methods for asset liability management models we propose a multi stage stochastic programming model for a dutch pension fund both randomly sampled event trees and event trees fitting the mean and the covariance of the return distribution are used for generating the coefficients of the stochastic program in order to investigate the performance of the model and the scenario generation procedures we conduct rolling horizon simulations the average cost and the risk of the stochastic programming policy are compared to the results of a simple fixed mix model we compare the average switching behavior of the optimal investment policies our results show that the performance of the multi stage stochastic program could be improved drastically by choosing an appropriate scenario generation method

impact of liquidity risk on variations in efficiency and productivity a panel gamma simulated maximum likelihood estimation abstract the objective of this study is to assess the importance of short and long run liquidity or debt risk on technical inefficiency and productivity an alternative panel estimator of normal gamma stochastic frontier model is proposed using a simulated maximum likelihood estimation technique empirical estimates indicate a difference in the parameter coefficients of gamma stochastic production function and heterogeneity function variables between the pooled and the swamy arora panel models the results from this study show short and long run risk or variations in liquidity or debt servicing ratio play an important role in explaining the variance in efficiency and productivity

has monetary policy become more effective we investigate the implications of changes in the structure of the u s economy for monetary policy effectiveness estimating a vector autoregression over the pre and post 1980 periods we provide evidence of a reduced effect of monetary policy shocks in the latter period we estimate a structural model that replicates well the economy s response in both periods and perform counterfactual experiments to determine the source of the change in the monetary transmission mechanism and in the economy s volatility we find that by responding more strongly to inflation expectations monetary policy has stabilized the economy more effectively in the post 1980 period

monetary policy regime shifts and inflation persistence abstract using bayesian methods we estimate a markov switching new keynesian msnk model that allows shifts in the monetary policy reaction coefficients and shock volatilities with u s data we find that a more aggressive monetary policy regime was in place after the volcker disinflation and before 1970 than during the great inflation of the 1970s our estimates also indicate that a low volatility regime has been in place during most of the sample period after 1984 we connect the timing of the different regimes to a measure of inflation persistence

uncertainty and fiscal cliffs motivated by the us fiscal cliin 2012 this paper considers the short and longer term impact of uncertainty generated by scal policy empirical evidence shows in creases in economic policy uncertainty lower investment and employment investment that is longer lived and subject to a longer planning horizon responds to policy uncer tainty with a lag while capital that depreciates more quickly and can be installed with few costs falls immediately a dsge model incorporating uncertainty over future tax regimes produces responses to scal uncertainty that match key features of the data the model features uncertainty over the average tax rate and rational expectations about the resolution of uncertainty with speci c outcomes and timing uncertainty injects noise into the economy and lowers the level of economic activity

has fiscal policy helped stabilize the postwar u s economy abstract in this paper i consider whether postwar fiscal policy has helped stabilize the u s economy i do this by adding to the stochastic growth model fiscal policy feedback rules estimated from postwar data these rules allow fiscal policies to respond to current and lagged output and labor hours i use the estimated policy rules to see if postwar fiscal policy reduces output volatility and or lengthens expansions and shortens recessions i find that fiscal policy in general provides little stability on either count i also find that the endogenous feedback links by themselves can provide some stabilization

policy regimes policy shifts and u s business cycles abstract using an estimated dsge model with monetary and fiscal policy interactions and allowing for equilibrium indeterminacy we find that a passive monetary and passive fiscal policy regime prevailed in the pre volcker period this gave rise to self fulfilling beliefs and unconventional transmission mechanisms of policy shifts unanticipated increases in interest rates increased inflation and output while unanticipated increases in lump sum taxes decreased inflation and output we show that had the monetary policy regime of the post volcker era been in place pre volcker inflation volatility would have been lower by 25 and the rise of inflation in the 1970s would not have occurred

fiscal policy in general equilibrium this paper studies four classic fiscal policy experiments within a quantitatively restricted neoclassical model the authors main findings are as follows 1 permanent changes in government purchases can lead to short run and long run output multipliers that exceed one 2 permanent changes in government purchases induce larger effects than temporary changes 3 the financing decision is quantitatively more important than the resource cost of changes in government purchases and 4 public investment has dramatic effects on private output and investment these findings stem from important dynamic interactions of capital and labor absent in earlier equilibrium analyses of fiscal policy copyright 1993 by american economic association

changing macroeconomic dynamics at the zero lower bound this article develops a change point var model that isolates four major macroeconomic regimes in the us since the 1960s the model identifies shocks to demand supply monetary policy and spread yield using restrictions from a general equilibrium model the analysis discloses important changes to the statistical properties of key macroeconomic variables and their responses to the identified shocks during the crisis period spread shocks became more important for movements in unemployment and inflation a counterfactual exercise evaluates the importance of lower bond yield spread during the crises and suggests that the fed s large scale asset purchases helped lower the unemployment rate by about 0 6 percentage points while boosting inflation by about 1 percentage point

trend inflation indexation and inflation persistence in the new keynesian phillips curve purely forward looking versions of the new keynesian phillips curve nkpc generate too little inflation persistence some authors add ad hoc backward looking terms to address this shortcoming we hypothesize that inflation per sistence results mainly from variation in the long run trend component of inflation which we attribute to shifts in monetary policy we derive a version of the nkpc that incorporates a time varying inflation trend and examine whether it explains the dynamics of inflation when drift in trend inflation is taken into account a purely forward looking version of the model fits the data well and there is no need for backward looking components jel e12 e31 e52 in this paper we consider the extent to which guillermo calvo s 1983 model of nominal price rigidities can explain inflation dynamics without relying on arbitrary backward looking terms in its baseline formulation the calvo model leads to a purely forward looking new keynesian

were there regime switches in u s monetary policy working paper 2004 14 june 2004 abstract a multivariate model identifying monetary policy and allowing for simultaneity and regime switching in coefficients and variances is confronted with u s data since 1959 the best fit is with a model that allows time variation in structural disturbance variances only among models that also allow for changes in equation coefficients the best fit is for a model that allows coefficients to change only in the monetary policy rule that model allows switching among three main regimes and one rarely and briefly occurring regime the three main regimes correspond roughly to periods when most observers believe that monetary policy actually differed and the differences in policy behavior are substantively interesting though statistically ill determined the estimates imply monetary targeting was central in the early 80s but was also important sporadically in the 70s the changes in regime were essential neither to the rise in inflation in the 70s nor to its decline in the 80s jel classification e52 e47 c53 key words counterfactuals lucas critique policy rule monetary targeting simultaneity volatility model comparison i the debate over monetary policy change in an influential paper clarida gali and gertler 2000 cgg presented evidence that us monetary policy changed between the 1970 s and the 1980 s indeed that in the 70 s it was drastically worse they found that the policy rule apparently followed in the 70 s was one that when embedded in most stochastic general equilibrium models would imply non uniqueness of the equilibrium and hence vulnerability of the economy to sunspot fluctuations of arbitrarily large size their estimated policy rule for the later period on the other hand eliminated this indeterminacy these results are a possible explanation of the volatile and rising inflation of the 70 s and of its subsequent decline the cgg analysis has two important weaknesses one is that it fails to account for stochastic volatility us macroeconomic variables and particularly the federal funds rate have gone through periods of tranquility and of agitation with forecast error variances varying greatly from period to period ignoring such variation does not lead to inconsistent estimates of model parameters when the forecasting equations themselves are constant but it strongly biases toward a finding of changed parameters tests of the stability of the forecasting equations the other weakness is that the cgg analysis rests on powerful and implausible identifying assumptions they require that we accept that the response of the monetary authority to expected future inflation and output does not depend on the recent history of inflation money growth or output it is hard to understand why this should be so especially in the 70 s when monetarism was a prominent theme in policy debates congress was requiring reports from the fed of projected time paths of monetary aggregates and financial markets were reacting sensitively to weekly money supply numbers the requirement for existence and uniqueness of equilibrium in dynamic models is that the monetary policy rule show a more than unit response of interest rates to the sum of the logs of all nominal variables that appear on the right hand side of the reaction function if we force a particular measure of expected future inflation to proxy for all the nominal variables that actually appear independently in the reaction function we are bound to get distorted conclusions on the one hand because expected future inflation will be a noisy measure of the full set of nominal influences on policy we might get downward bias in our estimates from the usual errorsin variables effect on the other hand to the extent that expected future inflation like most expected future values shows less variation than current nominal variables we could find a mistaken scaling up of coefficients

inflation dynamics the role of public debt and policy regimes abstract in a passive monetary and active fiscal policy regime changes in the value of public debt generate wealth effects on households then in contrast to the active monetary and passive fiscal policy regime inflation moves oppositely from the inflation target and a stronger reaction of interest rates to inflation increases the response of inflation to shocks moreover a higher level of public debt increases the response of inflation while a weaker reaction of taxes to debt decreases the response of inflation to shocks in a passive monetary and passive fiscal policy regime both monetary and fiscal policy parameters affect inflation

long term debt and optimal policy in the fiscal theory of the price level the fiscal theory says that the price level is determined by the ratio of nominal debt to the present value of real primary surpluses i analyze long term debt and optimal policy in the fiscal theory i find that the maturity structure of the debt matters for example it determines whether news of future deficits implies current inflation or future inflation when long term debt is present the government can trade current inflation for future inflation by debt operations this tradeoff is not present if the government rolls over short term debt the maturity structure of outstanding debt acts as a budget constraint determining which periods price levels the government can affect by debt variation alone in addition debt policythe expected pattern of future state contingent debt sales repurchases and redemptionsmatters crucially for the effects of a debt operation i solve for optimal debt policies to minimize the variance of inflation i find cases in which long term debt helps to stabilize inflation i also find that the optimal policy produces time series that are similar to u s surplus and debt time series to understand the data i must assume that debt policy offsets the inflationary impact of cyclical surplus shocks rather than causing price level disturbances by policy induced shocks shifting the objective from price level variance to inflation variance the optimal policy produces much less volatile inflation at the cost of a unit root in the price level this is consistent with the stabilization of u s inflation after the gold standard was abandoned

on the impossibility of protecting risk takers risk neutral sellers can extract high profits from risk loving buyers by oering them lotteries to limit risk taking gambling is heavily regulated in most countries i show that protecting risk loving buyers is essentially impossible even if buyers are risk loving only asymptotically the seller can construct a nonrandom winner pays auction that ensures unbounded profits buyers are asymptotically risk loving for example when their preferences satisfy savage s axioms or they have prospect theory preferences the profits are unbounded even if the seller cannot use any mechanism that resembles a lottery

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

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

a mixed integer linear programming model for optimal sovereign debt issuance abstract governments borrow funds to finance the excess of cash payments or interest payments over receipts usually by issuing fixed income debt and index linked debt the goal of this work is to propose a stochastic optimization based approach to determine the composition of the portfolio issued over a series of government auctions for the fixed income debt to minimize the cost of servicing debt while controlling risk and maintaining market liquidity we show that this debt issuance problem can be modeled as a mixed integer linear programming problem with a receding horizon the stochastic model for the interest rates is calibrated using a kalman filter and the future interest rates are represented using a recombining trinomial lattice for the purpose of scenario based optimization the use of a latent factor interest rate model and a recombining lattice provides us with a realistic yet very tractable scenario generator and allows us to do a multi stage stochastic optimization involving integer variables on an ordinary desktop in a matter of seconds this in turn facilitates frequent re calibration of the interest rate model and re optimization of the issuance throughout the budgetary year allows us to respond to the changes in the interest rate environment we successfully demonstrate the utility of our approach by out of sample back testing on the uk debt issuance data

the backing of government bonds and monetarism abstract this paper examines the implications of the fiscal backing of government bonds for the effects of conventional macroeconomic policies and in particular for certain monetarist propositions it shows that the validity of some basic monetarist hypotheses requires a considerable degree of accommodation by the fiscal authority relative to the central bank otherwise government bonds may matter in a manner as described in the traditional literature e g mundell 1971 patinkin 1965 though some differences arise of perhaps independent interest the framework developed in the analysis is an intertemporal general equilibrium model with all the descriptive features of the conventional flexible price is lm model
