What measure of inflation should a central bank target? by N. Gregory Mankiw( Book )
21 editions published in 2002 in English and held by 68 libraries worldwide
This paper assumes that a central bank commits itself to maintaining an inflation target and then asks what measure of the inflation rate the central bank should use if it wants to maximize economic stability. The paper first formalizes this problem and examines its microeconomic foundations. It then shows how the weight of a sector in the stability price index depends on the sector's characteristics, including size, cyclical sensitivity, sluggishness of price adjustment, and magnitude of sectoral shocks. When a numerical illustration of the problem is calibrated to U.S. data, one tentative conclusion is that a central bank that wants to achieve maximum stability of economic activity should use a price index that gives substantial weight to the level of nominal wages
Inattentive consumers by Ricardo Reis( Book )
19 editions published between 2004 and 2005 in English and held by 57 libraries worldwide
This paper studies the consumption decisions of agents who face costs of acquiring, absorbing and processing information. These consumers rationally choose to only sporadically update their information and re-compute their optimal consumption plans. In between updating dates, they remain inattentive. This behavior implies that news disperses slowly throughout the population, so events have a gradual and delayed effect on aggregate consumption. The model predicts that aggregate consumption adjusts slowly to shocks, and is able to explain the excess sensitivity and excess smoothness puzzles. In addition, individual consumption is sensitive to ordinary and unexpected past news, but it is not sensitive to extraordinary or predictable events. The model further predicts that some people rationally choose to not plan, live hand-to-mouth, and save less, while other people sporadically update their plans. The longer are these plans, the more they save. Evidence using U.S. aggregate and microeconomic data generally supports these predictions

Sticky information : a model of monetary nonneutrality and structural slumps by N. Gregory Mankiw( Book )
16 editions published in 2001 in English and held by 52 libraries worldwide
This paper explores a model of wage adjustment based on the assumption that information disseminates slowly throughout the population of wage setters. This informational frictional yields interesting and plausible dynamics for employment and inflation in response to exogenous movements in monetary policy and productivity. In this model, disinflations and productivity slowdowns have a parallel effect: They both cause the path of employment to fall below the level that would prevail under full information. The model implies that, in the face of productivity change, a policy of targeting either nominal income or the nominal wage leads to more stable employment than does a policy of targeting the price of goods and services. Finally, we examine U.S. time series and find that, as the model predicts, unemployment fluctuations are associated with both inflation and productivity surprises
The time-series properties of aggregate consumption : implications for the costs of fluctuations by Ricardo Reis( Book )
19 editions published in 2005 in English and held by 50 libraries worldwide
While this is typically ignored, the properties of the stochastic process followed by aggregate consumption affect the estimates of the costs of fluctuations. This paper pursues two approaches to modelling aggregate consumption dynamics and to measuring how much society dislikes fluctuations, one statistical and one economic. The statistical approach estimates the properties of consumption and calculates the cost of having consumption fluctuating around its mean growth. The paper finds that the persistence of consumption is a crucial determinant of these costs and that the high persistence in the data severely distorts conventional measures. It shows how to compute valid estimates and confidence intervals. The economic approach uses a calibrated model of optimal consumption and measures the costs of eliminating income shocks. This uncovers a further cost of uncertainty, through its impact on precautionary savings and investment. The two approaches lead to costs of fluctuations that are higher than the common wisdom, between 0.5% and 5% of per capita consumption
Monetary policy for inattentive economies by Laurence M Ball( Book )
14 editions published in 2003 in English and held by 50 libraries worldwide
This paper is a contribution to the analysis of optimal monetary policy. It begins with a critical assessment of the existing literature, arguing that most work is based on implausible models of inflation-output dynamics. It then suggests that this problem may be solved with some recent behavioral models, which assume that price setters are slow to incorporate macroeconomic information into the prices they set. A specific such model is developed and used to derive optimal policy. In response to shocks to productivity and aggregate demand, optimal policy is price level targeting. Base drift in the price level, which is implicit in the inflation targeting regimes currently used in many central banks, is not desirable in this model. When shocks to desired markups are added, optimal policy is flexible targeting of the price level. That is, the central bank should allow the price level to deviate from its target for a while in response to these supply shocks, but it should eventually return the price level to its target path. Optimal policy can also be described as an elastic price standard: the central bank allows the price level to deviate from its target when output is expected to deviate from its natural rate
A cost-of-living dynamic price index, with an application to indexing retirement accounts by Ricardo Reis( Book )
15 editions published in 2005 in English and held by 49 libraries worldwide
If a consumer wishes to protect her retirement account from the risk of price changes in order to sustain a stable standard of living, then what price index should the account be indexed to? This paper constructs a dynamic price index (DPI) that answers this question. Unlike the existing theory on price indices (which is static and certain), the DPI measures the cost of living for a consumer who lives for many periods and faces uncertainty. The first contribution of this research is to define this price index and study its theoretical properties. The DPI: is homogeneous of degree 1 with respect to all prices, is forward-looking with respect to price shocks, responds more to permanent vis- -vis transitory price changes, includes asset prices with a potentially large weight, and distinguishes between durable and non-durable goods prices. The second contribution of the paper is to construct a DPI for the United States from 1970 to 2004. It gives an account of the cost of living in the U.S. that is strikingly different from the one provided by the CPI. The DPI is less persistent, more volatile, and a large part of its movements are driven by changes in the prices of houses and bonds
Inattentive producers by Ricardo Reis( Book )
15 editions published between 2005 and 2006 in English and held by 49 libraries worldwide
"I present and solve the problem of a producer who faces costs of acquiring, absorbing, and processing information. I establish a series of theoretical results describing the producer's behavior. First, I find the conditions under which she prefers to set a plan for the price she charges, or instead prefers to set a plan for the quantity she sells. Second, I show that the agent rationally chooses to be inattentive to news, only sporadically updating her information. I solve for the optimal length of inattentiveness and characterize its determinants. Third, I explicitly aggregate the behavior of many such producers. I apply these results to a model of inflation. I find that the model can fit the quantitative facts on post-war inflation remarkably well, that it is a good forecaster of future inflation, and that it survives the Lucas critique by fitting also the pre-war facts on inflation moderately well"--National Bureau of Economic Research web site
Sticky information versus sticky prices : a proposal to replace the new Keynesian Phillips curve by N. Gregory Mankiw( Book )
15 editions published in 2001 in English and held by 49 libraries worldwide
This paper examines a model of dynamic price adjustment based on the assumption that information disseminates slowly throughout the population. Compared to the commonly used sticky-price model, this sticky-information model displays three, related properties that are more consistent with accepted views about the effects of monetary policy. First, disinflations are always contractionary (although announced disinflations are less contractionary than surprise ones). Second, monetary policy shocks have their maximum impact on inflation with a substantial delay. Third, the change in inflation is positively correlated with the level of economic activity
Disagreement about inflation expectations by N. Gregory Mankiw( Book )
15 editions published in 2003 in English and held by 49 libraries worldwide
Analyzing 50 years of inflation expectations data from several sources, we document substantial disagreement among both consumers and professional economists about expected future inflation. Moreover, this disagreement shows substantial variation through time, moving with inflation, the absolute value of the change in inflation, and relative price variability. We argue that a satisfactory model of economic dynamics must speak to these important business cycle moments. Noting that most macroeconomic models do not endogenously generate disagreement, we show that a simple sticky-information' model broadly matches many of these facts. Moreover, the sticky-information model is consistent with other observed departures of inflation expectations from full rationality, including autocorrelated forecast errors and insufficient sensitivity to recent macroeconomic news
Pervasive stickiness : (expanded version) by N. Gregory Mankiw( Book )
18 editions published in 2006 in English and held by 40 libraries worldwide
This paper explores a macroeconomic model of the business cycle in which stickiness of information is pervasive. We start from a familiar benchmark classical model and add to it the assumption that there is sticky information on the part of consumers, workers, and firms. We evaluate the model against three key facts that describe short-run fluctuations: the acceleration phenomenon, the smoothness of real wages, and the gradual response of real variables to shocks. We find that pervasive stickiness is required to fit the facts. We conclude that models based on stickiness of information offer the promise of fitting the facts on business cycles while adding only one new plausible ingredient to the classical benchmark
The brevity and violence of contractions and expansions by Alisdair McKay( Book )
16 editions published in 2006 in English and held by 34 libraries worldwide
Early studies of business cycles argued that contractions in economic activity were briefer (shorter) and more violent (rapid) than expansions. This paper systematically investigates this claim and in the process discovers a robust new business cycle fact: expansions and contractions in output are equally brief and violent but contractions in employment are briefer and more violent than expansions. The difference arises because employment typically lags output around peaks but both series roughly coincide in their troughs. We discuss the performance of existing business cycle models in accounting for this fact, and conclude that none can fully account for it. We then show that a simple model that combines three familiar ingredients-labor hoarding, a choice of when to scrap old technologies, and job training or job search-can account for the business cycle fact
VLSI-SoC : design methodologies for SOC and SIP : 16th IFIP WG 10.5/IEEE International Conference on Very Large Scale Integration, VLSI-SoC 2008, Rhodes Island, Greece, October 13-15, 2008 : revised selected papers by Christian Piguet( Book )
14 editions published between 2010 and 2014 in English and held by 29 libraries worldwide
This book contains extended and revised versions of the best papers that were sented during the 16th edition of the IFIP/IEEE WG10.5 International Conference on Very Large Scale Integration, a global System-on-a-Chip Design & CAD conference. The 16th conference was held at the Grand Hotel of Rhodes Island, Greece (October 13-15, 2008). Previous conferences have taken place in Edinburgh, Trondheim, V- couver, Munich, Grenoble, Tokyo, Gramado, Lisbon, Montpellier, Darmstadt, Perth, Nice and Atlanta. VLSI-SoC 2008 was the 16th in a series of international conferences sponsored by IFIP TC 10 Working Group 10.5 and IEEE CEDA that explores the state of the art and the new developments in the field of VLSI systems and their designs. The purpose of the conference was to provide a forum to exchange ideas and to present industrial and research results in the fields of VLSI/ULSI systems, embedded systems and - croelectronic design and test
Relative goods' prices and pure inflation by Ricardo Reis( Book )
17 editions published in 2007 in English and held by 27 libraries worldwide
This paper uses a dynamic factor model for the quarterly changes in consumption goods' prices to separate them into three components: idiosyncratic relative-price changes, aggregate relative-price changes, and changes in the unit of account. The model identifies a measure of "pure" inflation: the common component in goods' inflation rates that has an equiproportional effect on all prices and is uncorrelated with relative price changes at all dates. The estimates of pure inflation and of the aggregate relative-price components allow us to re-examine three classic macro-correlations. First, we find that pure inflation accounts for 15-20% of the variability in overall inflation, so that most changes in inflation are associated with changes in goods' relative prices. Second, we find that the Phillips correlation between inflation and measures of real activity essentially disappears once we control for goods' relative-price changes. Third, we find that, at business-cycle frequencies, the correlation between inflation and money is close to zero, while the correlation with nominal interest rates is around 0.5, confirming previous findings on the link between monetary policy and inflation
Correlated disturbances and U.S. business cycles by Vasco Cúrdia( Book )
15 editions published between 2010 and 2011 in English and Undetermined and held by 26 libraries worldwide
The dynamic stochastic general equilibrium (DSGE) models that are used to study business cycles typically assume that exogenous disturbances are independent autoregressions of order one. This paper relaxes this tight and arbitrary restriction, by allowing for disturbances that have a rich contemporaneous and dynamic correlation structure. Our first contribution is a new Bayesian econometric method that uses conjugate conditionals to make the estimation of DSGE models with correlated disturbances feasible and quick. Our second contribution is a re-examination of U.S. business cycles. We find that allowing for correlated disturbances resolves some conflicts between estimates from DSGE models and those from vector autoregressions, and that a key missing ingredient in the models is countercyclical fiscal policy. According to our estimates, government spending and technology disturbances play a larger role in the business cycle than previously ascribed, while changes in markups are less important
Targeted transfers and the fiscal response to the Great Recession by Hyunseung Oh( Book )
12 editions published in 2011 in English and held by 22 libraries worldwide
Between 2007 and 2009, government expenditures increased rapidly across the OECD countries. While economic research on the impact of government purchases has flourished, in the data, about three quarters of the increase in expenditures in the United States (and more in other countries) was in government transfers. We document this fact, and show that the increase in U.S. spending on retirement, disability, and medical care has been as high as the increase in government purchases. We argue that future research should focus on the positive impact of transfers. Towards this, we present a model in which there is no representative agent and Ricardian equivalence does not hold because of uncertainty, imperfect credit markets, and nominal rigidities. Targeted lump-sum transfers are expansionary both because of a neoclassical wealth effect and because of a Keynesian aggregate demand effect
Imperfect information and aggregate supply by N. Gregory Mankiw( Book )
12 editions published between 2010 and 2011 in English and Undetermined and held by 22 libraries worldwide
This paper surveys the research in the past decade on imperfect information models of aggregate supply and the Phillips curve. This new work has emphasized that information is dispersed and disseminates slowly across a population of agents who strategically interact in their use of information. We discuss the foundations on which models of aggregate supply rest, as well as the micro-foundations for two classes of imperfect information models: models with partial information, where agents observe economic conditions with noise, and models with delayed information, where they observe economic conditions with a lag. We derive the implications of these two classes of models for: the existence of a non-vertical aggregate supply, the persistence of the real effects of monetary policy, the difference between idiosyncratic and aggregate shocks, the dynamics of disagreement, and the role of transparency in policy. Finally, we present some of the topics on the research frontier in this area -- National Bureau of Economic Research web site
