interpreting economic time series this paper explores some of the implications for econometric practice of the principle that people s observed behavior will change when their constraints change in dynamic contexts a proper definition of people s constraints includes among them laws of motion that describe the evolution of the taxes they must pay and the prices of the goods that they buy and sell changes in agents perceptions of these laws of motion or constraints will in general produce changes in the schedules that describe the choices they make as a function of the information that they possess until very recently received dynamic econometric practice ignored this principle the practice of dynamic econometrics should be changed so that it is consistent with the principle that people s rules of choice are influenced by their constraints this is a substantial undertaking and involves major adjustments in the ways that we formulate estimate and simulate econometric models

finance inflation and employment a post keynesian kaleckian analysis the purpose of this paper is to contribute to the post keynesian kaleckian macroeconomic literature we develop a macroeconomic model that explicitly integrates the role of borrowing and cash payment commitments on outstanding debt interest plus principal repayment into the consumption and investment expenditures as well as into the inflation generating process we explore the way that finance influences the distribution effects of inflation in the demand side of a money credit using economy we suggest a new phillips curve that encapsulates the impact of financial commitments on wage and profit claims we argue that high debt and cash payment commitments are likely to be associated with a positive demand side effect of inflation on the rate of employment and that they might be conducive to a negative supply side effect of employment on the inflation rate the author 2011 published by oxford university press on behalf of the cambridge political economy society all rights reserved

estimation of the inconvenience cost of a rolling blackout in the residential sector the case of south korea abstract south korea is experiencing a serious imbalance in electricity supply and demand which caused a blackout in 2011 the korean government has planned to perform a rolling blackout to prevent large scale blackouts when the electricity supply reserve margin reaches less than 1 million kw this study attempts to estimate the inconvenience cost of household customers from a rolling blackout by using survey data to this end we apply a contingent valuation method cvm to measure their willingness to pay wtp in order to avoid a rolling blackout i e the suspension of electricity supply in this study we estimate the inconvenience costs stemming from both an unannounced and an announced rolling blackout as a result we find that the inconvenience cost of a sudden rolling blackout is estimated at 3900 67 krw 3 56 usd per month per household while that of an announced rolling blackout stands at 3102 95 krw 2 83 usd this difference in costs shows that people place value in receiving prior notice of a blackout and that inconvenience costs of between 166 0 billion krw 151 6 million usd and 174 3 billion krw 159 2 million usd per year can be reduced nationwide by giving households advance notice of a planned rolling blackout

macroeconomics after the crisis time to deal with the pretense of knowledge syndrome the recent financial crisis has damaged the reputation of macroeconomics largely for its inability to predict the impending financial and economic crisis to be honest this inability to predict does not concern me much it is almost tautological that severe crises are essentially unpredictable for otherwise they would not cause such a high degree of distress what does concern me about my discipline is that its current core by which i mainly mean the so called dynamic stochastic general equilibrium approach has become so mesmerized with its own internal logic that it has begun to confuse the precision it has achieved about its own world with the precision that it has about the real one this is dangerous for both methodological and policy reasons to be fair to our field an enormous amount of work at the intersection of macroeconomics and corporate finance has been chasing many of the issues that played a central role during the current crisis including liquidity evaporation collateral shortages bubbles crises panics fire sales risk shifting contagion and the like however much of this literature belongs to the periphery of macroeconomics rather than to its core i will discuss the distinction between the core and the periphery of macroeconomics as well as the futile nature of the integrationist movement that is the process of gradually bringing the insights of the periphery into the dynamic stochastic general equilibrium structure i argue that the complexity of macroeconomic interactions limits the knowledge we can ever attain and that we need to place this fact at the center of our analysis we should consider what this complexity does to the actions and reactions of the economic agent and seek analytical tools and macroeconomic policies that are robust to the enormous uncertainty to which we are confined

house price booms current account deficits and low interest rates one of the most striking features of the period before the great recession is the strong positive correlation between house price appreciation and current account defi cits not only in the united states but also in other countries that have subsequently experienced the highest degree of fi nancial turmoil a progressive relaxation of credit standards can rationalize this empirical observation lower collateral requirements facilitate access to external funding and drive up house prices the current account turns negative because households borrow from the rest of the world at the same time however the world real interest rate counterfactually increases the two key ingredients that reconcile a demand based explanation of house price booms and current account defi cits with the evidence on real interest rates are nominal interest rates lower than the predictions of a standard monetary policy rule in leveraged economies and foreign exchange rate pegs in saving countries

an interest rate spread based measure of turkish monetary policy a coherent method to measure the effectiveness of a monetary policy improves the monetary authority s management capacity and renders the possibility of applying sound policies prior to and during a crisis the trend in employing complicated and ambiguity bearing unconventional monetary tools in the aftermath of the 2008 crisis has increased the value of such a method the aim of this article is to introduce a coherent and consistent monetary policy evaluation method for turkey accordingly we suggest that innovations in the spread between overnight interest rates and treasury auction interest rates are informative for exchange rate output and prices empirical evidence for this identification reveals that positive innovation in spread implying a tight monetary policy measure decreases output temporarily permanently decreases prices and appreciates local currency this result is also robust to alternative specifications

menu costs and phillips curves this paper develops a model of a monetary economy in which individual firms are subject to idiosyncratic productivity shocks as well as general inflation sellers can change price only by incurring a real menu cost we calibrate this cost and the variance and autocorrelation of the idiosyncratic shock using a new u s data set of individual prices due to klenow and kryvtsov the prediction of the calibrated model for the effects of high inflation on the frequency of price changes accords well with international evidence from various studies the model is also used to conduct numerical experiments on the economy s response to various shocks in none of the simulations we conducted did monetary shocks induce large or persistent real responses

turnout political preferences and information experimental evidence from peru abstract i combine a field experiment with a change in voting laws reducing the fine for abstention to assess the effects of monetary incentives to encourage voter participation in a real world election using experimental variation in the perceived reduction of the fine for abstention i estimate that receiving information about a reduction in the fine by 50 75 percent causes a decrease in turnout of 2 6 5 3 percentage points these estimates imply a cost elasticity of voting of 0 22 the reduction in turnout is driven by voters who are in the center of the political spectrum hold less political information and have lower subjective value of voting the increase in abstention does not change aggregate preferences for specific policies further involvement in politics as measured by the decision to acquire political information is independent of the level of the fine additional results indicate that the reduction in the fine reduces the incidence of vote buying and increases the price paid for a vote

how much should inflation targeters care about the exchange rate abstract a dsge model is used to examine whether including the exchange rate in the central bank s policy rule can improve economic performance smoothing the exchange rate helps both financially robust economies and financially vulnerable emerging economies in handling risk premium shocks and given a small weight placed on the exchange rate the effects on inflation and output volatility are minimal with demand and cost push shocks financially vulnerable economies are especially likely to benefit from exchange rate smoothing due to perverse movements of the exchange rate they experience when hit by demand shocks and being more prone to risk premium shocks

rethinking macroeconomics what failed and how to repair it the standard macroeconomic models have failed by all the most important tests of scientific theory they did not predict that the financial crisis would happen and when it did they understated its effects monetary authorities allowed bubbles to grow and focused on keeping inflation low partly because the standard models suggested that low inflation was necessary and almost sufficient for efficiency and growth after the crisis broke policymakers relying on the models floundered notwithstanding the diversity of macroeconomics the sum of these failures points to the need for a fundamental re examination of the models and a reassertion of the lessons of modern general equilibrium theory that were seemingly forgotten in the years leading up to the crisis this paper first describes the failures of the standard models in broad terms and then develops the economics of deep downturns and shows that such downturns are endogenous further the paper argues that there have been systemic changes to the structure of the economy that made the economy more vulnerable to crisis contrary to what the standard models argued finally the paper contrasts the policy implications of our framework with those of the standard models

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

five facts about prices a reevaluation of menu cost models are price decreases 3 the frequency of price increases covaries strongly with inflation whereas the frequency of price decreases and the size of price increases and price decreases do not 4 the frequency of price change is highly seasonal it is highest in the first quarter and then declines 5 we find no evidence of upwardsloping hazard functions of price changes for individual products we show that the first second and third facts are consistent with a benchmark menu cost model whereas the fourth and fifth facts are not

semiparametric estimates of monetary policy effects string theory revisited we develop flexible semiparametric time series methods for the estimation of the causal effect of monetary policy on macroeconomic aggregates our estimator captures the average causal response to discrete policy interventions in a macrodynamic setting without the need for assumptions about the process generating macroeconomic outcomes the proposed estimation strategy based on propensity score weighting easily accommodates asymmetric and nonlinear responses using this estimator we show that monetary tightening has clear effects on the yield curve and on economic activity monetary accommodation however appears to generate less pronounced responses from both estimates for recent financial crisis years display a similarly dampened response to monetary accommodation

the taylor rule and optimal monetary policy where it denotes the fed s operating target for the federal funds rate pt is the inflation rate measured by the gdp deflator yt is the log of real gdp and y t is the log of potential output identified empirically with a linear trend the rule has since been subject to considerable attention both as an account of actual policy in the united states and elsewhere and as a prescription for desirable policy taylor argues for the rule s normative significance both on the basis of simulations and on the ground that it describes u s policy in a period in which monetary policy is widely judged to have been unusually successful taylor 1999 suggesting that the rule is worth adopting as a principle of behavior here i wish to consider to what extent this prescription resembles the sort of policy that economic theory would recommend i consider the question in the context of a simple but widely used optimizing model of the monetary transmission mechanism which allows one to reach clear conclusions about economic welfare the model is highly stylized but incorporates important features of more realistic models and allows me to make several points that are of more general validity out of concern for the robustness of the conclusions reached the analysis here addresses only broad qualitative features of the taylor rule and attempts to identify features of a desirable policy rule that are likely to hold under a variety of model specifications

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

optimal reputation building in the new keynesian model abstract we study the optimal committed monetary policy when the private sector has imperfect information and has to infer the central banker s ability to commit the optimal policy is designed to influence learning and improve the central banker s reputation of being committed the reputation building implies that when a committed central banker first takes office he should resist the temptation to stimulate output with initially high but declining inflation he should reverse a missed inflation target rather than accommodate it and he should adopt a less accommodative inflation response to a cost push shock than a full commitment solution suggests

inflation targeting in colombia 2002 2012 proquest denotes formulae omitted over the last twenty years nearly thirty countries have adopted inflation targeting regimes to conduct monetary policy in addition to the announce ment of specific inflation targets inflation targeting regimes have been characterized by increased transparency enhanced communication with the public and explicit accountability mechanisms moreover their policy strategy is based on setting short run interest rates rather than on targeting monetary aggregates in principle inflation targeting regimes also increase exchange rate flexibility the performance of inflation targeting regimes has been a matter of exten sive research for instance ball and sheridan and lin and ye conclude that in industrialized countries inflation targeting did not make a difference in inflation and output behavior 1 the spirit of these conclusions is echoed in two recent surveys on the performance of inflation targeting 2 another line of research on inflation targeting in industrialized countries studies its impact on sacrifice ratios output losses per point of inflation during monetary driven disinflations according to proponents inflation targeting anchors inflation expectations and it should thus allow for less costly disinflation processes while goncalves and carvalho find strong evidence supporting this hypoth esis in developed countries brito shows that the results are not robust to the inclusion of time effects 3 de roux and hofstetter conclude that inflation targeting allows for less costly disinflations even when controlling for time effects but only if disinflations are slow 4 for fast disinflations it does not yield less costly disinflations for developing countries the evidence is less conclusive goncalves and salles find that inflation targeting allows for a greater reduction in inflation and lower output volatility a result confirmed by lin and ye 5 brito and bystedt however suggest that the greater inflation reduction came at the expense of poorer output growth 6 in the surveys walsh concludes that evidence on inflation targeting in developing countries is clearly favorable to the regime while ball is more skeptical calling the outcomes inconclusive 7more recently de carvalho filho shows that during the recent global finan cial crisis inflation targeting nations outperformed non inflation targeting nations on several dimensions for both developed and developing economies their policy response was more aggressive they allowed the exchange rate to more effectively absorb the shocks and they recorded a stronger macro economic performance output industrial production and unemployment 8the vast empirical literature comparing performance across different mon etary regimes stands in contrast to the relatively scant research on the tools strategies goals and dilemmas faced by inflation targeting central banks espe cially in developing countries while there is good information on the overall comparative performance of these regimes little information is available on the political economy dimensions the increasing variety of instruments and goals of inflation targeting central banks and the challenges that lie ahead for them in this paper we fill part of this gap by examining the experience of the cen tral bank of colombia banco de la republica over the last decade a period of consolidation and innovation of its inflation targeting strategy colombia is one of five large latin american economies that have well established inflation targeting regimes along with brazil chile mexico and peru all of these countries adopted inflation targeting more than ten years ago yet their performance tools and goals have not been extensively studied cen tral banks in the region have used a variety of tools beyond short run policy interest rates including liquidity and reserve requirements credit provisions capital controls and interventions in the foreign exchange markets

macroeconomic modeling for monetary policy evaluation we describe some of the main features of the recent vintage macroeconomic models used for monetary policy evaluation we point to some of the key differences with respect to the earlier generation of macro models and highlight the insights for policy that these new frameworks have to offer our discussion emphasizes two key aspects of the new models the significant role of expectations of future policy actions in the monetary transmission mechanism and the importance for the central bank of tracking of the flexible price equilibrium values of the natural levels of output and the real interest rate we argue that both features have important implications for the conduct of monetary policy

the recent boom bust cycle the relative contribution of capital flows credit supply and asset bubbles abstract we use an estimated open economy dsge model with financial frictions for the us and the rest of the world to evaluate various competing explanations about the recent boom bust cycle we find that the savings glut hypothesis is insufficient for explaining all aspects of the boom in the us relatively strong tfp growth and expansionary monetary policy are also not able to explain fully the volatility of corporate and in particular residential investment we identify bubbles in the stock and housing market as crucial concerning the downturn in 2008 2009 the fall in house prices and residential investment only plays a minor role mortgage defaults have more explanatory power especially in a specification of the model with a segregated equity market finally the bursting of the stock market bubble was at least as important in this recession as in 2001 because of various negative shocks hitting the economy at the same time in 2008 2009 and continued positive technology growth not only the real interest rate declined but inflation fell rapidly and left insufficient room for monetary policy to play a similar stabilising role as in previous recessions

real business cycle views of the great depression and recent events a review of timothy j kehoe and edward c prescott s great depressions of the twentieth century this book collects essays most of which were published earlier into an advertisement for real business cycle rbc analysis half of the essays discuss the great depression half discuss events of the 1980s and 1990s they all use the general equilibrium model of economic growth to analyze short run fluctuations in the rate of economic growth of various countries i find that the use of closed economy models without frictions is not useful for the analysis of short run variations in the rate of economic growth almost all of these essays end by claiming that variations in the rate of gdp growth were due to changes in the rate of total factor productivity tfp growth they do not provide any explanation for fluctuations in the rate of tfp growth leaving the reader no closer to understanding these periods of depression and slow growth i discuss in turn the essays on the great depression the essays on more recent fluctuations and the definition of great depressions used in this volume

price and financial stability in modern central banking although the first central banks were created more than three hundred years ago it was not until the mid nineteenth century that central banks were given the monopoly power to issue banknotes and to act as lender of last resort thereafter central banks played the role of liquidity provider and lender of last resort these tasks were intended to allow a proper functioning of the payment system so financial stability was implicitly a major concern for central banks over time central banks moved toward achieving price stability from monetary stability to controlling inflation financial stability became a secondary goal if a goal at all this has not been the case in emerging market economies which have been affected by recurrent financial crises indeed financial crises like those of chile in the early 1980s or in mexico and asian countries in the 1990s are not radically different from the recent crisis in advanced economies the complexity may have changed but the original causes had many similarities 1 some years ago it was much more frequent to find central bankers concerned about financial stability in emerging countries than in advanced ones however as a consequence of the global financial crisis the issue of financial stability has reemerged as a top priority for policymakers in this paper i discuss the issue of price and financial stability in central banking i first explore the conduct of central banks in achieving price stability in particular in the context of inflation targeting and then move on to how the financial stability mandate has to be included as a key component of modern central banking i end with a few concluding remarks central banks and price stabilityas mentioned above central banks in advanced economies have long been focused mainly on ensuring low inflation moreover some scholars and practitioners argued that price stability should be the only objective of central banks so that the goal would be more credible and monetary policy more effective in achieving stability how exactly or operationally to achieve this target was an open question however some central banks tried to target monetary aggregates others to peg nominal exchange rates and others to use an eclectic mix of indicators two decades ago some central banks started conducting monetary policy targeting a specific value or range for the inflation rate this trend started with new zealand in 1990 and was followed by canada the united kingdom australia and sweden in the early 1990s this is a case in which policy development led academic advances progress on the academic front provided further impetus to the adoption of inflation targets as new models were developed to provide the theoretical underpinnings of inflation targets and the basis to conduct empirical work 2this view was further justified by the success of monetary policy around the world in providing stability not only on the inflation front but also in activity and employment the evidence that output volatility declined significantly in the united states after the mid 1980s was first reported by kim and nelson and later called the great moderation by stock and watson 3 several factors could be behind this trend such as technical progress better policies deeper financial markets and sheer good luck although there is no final verdict evidence points to the role of better macroeconomic policies 4 emerging market economies also enjoyed a great moderation but it came in the second half of the 1990s much later than in developed economies this coincided with the time in which inflation was conquered supporting the hypothesis that it was good policies rather than good luck 5 it is easy to discredit the great moderation in the current juncture however the resilience of emerging market economies to the global crisis was impressive indeed emerging markets had a recession but much milder than in the past and with a remarkable recovery

schumpeter meeting keynes a policy friendly model of endogenous growth and business cycles this paper studies an agent based model that bridges keynesian theories of demandgeneration and schumpeterian theories of technology fueled economic growth we employ the model to investigate the properties of macroeconomic dynamics and the impact of public polices on supply demand and the fundamentals of the economy we find profound complementarities between factors influencing aggregate demand and drivers of technological change that affect both short run fluctuations and longterm growth patterns from a normative point of view simulations show a corresponding complementarity between keynesian and schumpeterian policies in sustaining long run growth paths characterized by milder fluctuations and relatively lower unemployment levels the matching or mismatching between innovative exploration of new technologies and the conditions of demand generation appear to suggest the presence of two distinct regimes of growth or absence thereof characterized by different short run fluctuations and unemployment levels

has u s monetary policy tracked the efficient interest rate abstract interest rate decisions by central banks are universally discussed in terms of taylor rules which describe policy rates as responding to inflation and some measure of the output gap we show that an alternative specification of monetary policy in which the interest rate tracks the wicksellian efficient rate of return as the primary indicator of real activity fits the u s data better than otherwise identical taylor rules this result holds for a variety of specifications of the other ingredients of the policy rule including the output gap and of private agents behavior

taylor rules and exchange rate predictability in emerging economies abstract this study demonstrates the relationship between exchange rate determination and an endogenous monetary policy represented by taylor rules we fill a gap in the literature by focusing on a group of fifteen emerging economies that adopted free floating exchange rates and inflation targeting beginning in the mid 1990s because of the limited span of the time series which is a common obstacle to studying emerging economies we employ panel data regressions to produce more efficient estimates following the recent literature we use a robust set of out of sample statistics incorporating bootstrapped and asymptotic distributions for the diebold mariano statistic the clark and west statistic and theil s u ratio by evaluating different specifications for the taylor rule exchange rate model based on their out of sample performances we find that a present value forward looking specification shows strong evidence of exchange rate predictability

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

two monetary models with alternating markets we examine two monetary models with periodic interactions in centralized and decentralized markets the cash in advance model and the model in lagos and wright 2005 given conformity of preferences technologies and shocks both models reduce to a single difference equation in stationary equilibrium such equations coincide when the price distortion present in one model due to nash bargaining is replicated in the other using a tax on cash revenues in that case the quantitative implications for the welfare cost of inflation in each model are also comparable differences in the model s performance reduce to differences in the pricing mechanism assumed to govern those transactions that must be settled with the exchange of cash

the swing voter s curse the authors analyze two candidate elections in which some voters are uncertain about the realization of a state variable that affects the utility of all voters they demonstrate the existence of a swing voter s curse less informed indifferent voters strictly prefer to abstain rather than vote for either candidate even when voting is costless the swing voter s curse leads to the equilibrium result that a substantial fraction of the electorate will abstain even though all abstainers strictly prefer voting for one candidate over voting for another copyright 1996 by american economic association

the failure of models that predict failure distance incentives and defaults statistical default models widely used to assess default risk fail to account for a change in the relations between different variables resulting from an underlying change in agent behavior we demonstrate this phenomenon using data on securitized subprime mortgages issued in the period 1997 2006 as the level of securitization increases lenders have an incentive to originate loans that rate high based on characteristics that are reported to investors even if other unreported variables imply a lower borrower quality consistent with this behavior we find that over time lenders set interest rates only on the basis of variables that are reported to investors ignoring other credit relevant information as a result among borrowers with similar reported characteristics over time the set that receives loans becomes worse along the unreported information dimension this change in lender behavior alters the data generating process by transforming the mapping from observables to loan defaults to illustrate this effect we show that the interest rate on a loan becomes a worse predictor of default as securitization increases moreover a statistical default model estimated in a low securitization period breaks down in a high securitization period in a systematic manner it underpredicts defaults among borrowers for whom soft information is more valuable regulations that rely on such models to assess default risk could therefore be undermined by the actions of market participants

disinflation shocks in the eurozone a dsge perspective we investigate the effects of disinflation policies on key macroeconomic variables using euro area data and structural vector autoregressions svars we identify disinflation shocks as the only shocks that drive nominal variables to a lower long run level we find that in the immediate aftermath of a disinflation shock the euro area enters in a persistent recession we use these dynamic responses to estimate a dsge model with imperfect information about the disinflation shock we find that both nominal and real frictions and monetary policy gradualism have played a prominent role in the recessionary effect of disinflation shocks conversely allowing for imperfect credibility does not yield a better fit except when we shut key model s frictions down

exchange rate based stabilisation durables consumption and the stylised facts in this article we show that a model featuring durable consumer goods imperfect substitution between domestic and foreign assets and weak credibility can explain the qualitative and quantitative aspects of the stylised facts associated with exchange rate based stabilisation including the tremendous increase in real interest rates following a temporary reduction in the crawl total consumption spending rises 14 26 the real exchange rate appreciates 20 37 and the current account deficit swells to 10 15 of gross domestic product despite large capital inflows the real interest rate increases from 10 to 20 100

estimating the economic impacts of power supply interruptions abstract the cost of power system rationing which is a crucial parameter for determining optimal resilience investments is usually estimated using reduced form linear models or ordinary input output analysis however such methods do not properly address either consumers rational reactions to rationing policy or policy design nonlinearities to solve this problem this paper estimates the effects of power system rationing using a general equilibrium model the model solution shows that the power cut distribution among industries is a critical variable for quantifying policy effects and provides insights into optimal policy design
