decomposing the declining volatility of long term inflation expectations abstract the level and volatility of survey based measures of long term inflation expectations have come down dramatically over the past several decades to capture these changes in inflation dynamics we embed both short and long term expectations into a medium scale var model with stochastic volatility the model estimates attribute most of the marked decline in the volatility of expectations to smaller shocks to long run inflation expectations according to our estimates the volatility of shocks plummeted in the early to mid 1980s moved to a somewhat higher level that prevailed for much of the 1990s and then declined to and remained at very low levels

the fisher hypothesis and the forecastability and persistence of inflation abstract for the period 1860 to 1939 the simple correlation of the u s commercial paper rate with the contemporaneous inflation rate is 0 17 the corresponding correlation for the period 1950 to 1979 is 0 71 this paper attributes this apparent change in the fisher relation to differences in the stochastic process of inflation rather than a change in any structural relationship between interest rates and expected inflation contrary to recent claims in the literature there is little evidence of inflation non neutrality in data from the pre world war i period

an empirical analysis of life cycle fertility and female labor supply this paper examines us household fertility and female labor supply over the life cycle using data from the panel study of income dynamics the authors investigate how maternal time inputs and market expenditures on offspring as well as the benefits they yield their parents vary with ages of offspring and influence female labor supply and contraceptive behavior the econometric framework combines a female labor supply model and a contraceptive choice index function it also accounts for the fact that conceptions are not perfectly controllable events using longitudinal data on married couples the authors estimate these equations and test alternative specifications of the technologies governing child care the findings suggest that while parents cannot perfectly control conceptions variations in child care costs do affect life cycle spacing of births furthermore the results demonstrate the gains of modeling the linkages between female labor supply and fertility behavior at the household level authors modified

identifying the response of fertility to financial incentives summary while using financial incentives to increase fertility has become relatively common the effects of such policies are difficult to assess we propose an identification strategy that relies on the fact that the variation in wages induces variation in benefits and tax credits among comparable households we implement our approach by estimating a discrete choice model of female participation and fertility using individual data from the french labor force survey and a detailed representation of the french tax benefit system our results suggest that financial incentives have had a significant effect on fertility decisions in france as an example we simulate the effects of an additional unconditional child credit of 150 euros per month the effects are strongest for the third child copyright 2013 john wiley sons ltd

disinflation with imperfect credibility abstract this paper presents a theory of the real effects of disinflation as in new keynesian models price adjustment iis staggered across firms as in new classical models credibility is imperfect the monetary authority may not complete a promised disinflation the combination of imperfect credibility and staggering yields more plausible results than either of these assumptions alone in particular an announced disinflation reduces expected output if credibility is sufficiently low

the inexorable and mysterious tradeoff between inflation and unemployment this paper discusses the short run tradeoff between inflation and unemployment although this tradeoff remains a necessary building block of business cycle theory economists have yet to provide a completely satisfactory explanation for it according to the consensus view among central bankers and monetary economists a contractionary monetary shock raises unemployment at least temporarily and leads to a delayed and gradual fall in inflation standard dynamic models of price adjustment however cannot explain this pattern of responses reconciling the consensus view about the effects of monetary policy with models of price adjustment remains an outstanding puzzle for business cycle theorists several years ago i gave myself a peculiar assignment i decided to try to summarise all of economics in ten simply stated principles the purpose of this task was to introduce students to the economic way of thinking in the first chapter of my textbook principles of economics i figured if god could boil all of moral philosophy down to ten commandments i should be able to do much the same with economic science most of the ten principles i chose were microeconomic and hard to argue with they involved the importance of tradeoffs marginal analysis the benefits of trade market efficiency market failure and so on i allocated the last three principles to macroeconomics the first of these was a country s standard of living depends on its ability to produce goods and services which i viewed as the foundation of all growth theory the second was prices rise when the government prints too much money which i took to be the essence of classical monetary theory the last of my ten principles is the subject of today s lecture society faces a short run tradeoff between inflation and unemployment perhaps not surprisingly this statement turned out to be controversial when my publisher sent out the manuscript for review a few readers objected

why has u s inflation become harder to forecast we examine whether the u s rate of price inflation has become harder to forecast and to the extent that it has what changes in the inflation process have made it so the main finding is that the univariate inflation process is well described by an unobserved component trend cycle model with stochastic volatility or equivalently an integrated moving average process with time varying parameters this model explains a variety of recent univariate inflation forecasting puzzles and begins to explain some multivariate inflation forecasting puzzles as well

information rigidities inflation perceptions and the media lessons from the euro cash changeover the objective of theoretical models of information rigidities is to capture the fact that people are constrained in their ability to acquire and process all available information given that most people obtain their information about the economy from the media press coverage of the economy may exert an influence on peoples attitudes this paper tests for this influence by examining consumers inflation perceptions in the aftermath of the euro cash changeover which serves as a natural experiment using a new data set that quantifies the intensity and tone of media reports we document that media reporting has had a statistically significant and economically meaningful impact on inflation perceptions and contributed to their sharp rise in the aftermath of the euro cash changeover and to the divergence between inflation perceptions and actual inflation rates jel e53 d83

dynamics of health and labor market risks while there is little doubt that the probability of poor health increases with age and that less healthy people face a more difficult situation on the labor market the precise relationship between facing the risks of health deterioration and labor market instability is not well understood using 12 years of data from the german socio economic panel we study the nature of the relationship between poor health and non employment on a sample of german men aged 30 59 we propose a joint model of health and labor market risks which identifies the mechanism through which poor health contributes to the probability of being jobless and vice versa we find an important role of unobserved heterogeneity and evidence for correlation in the unobservable characteristics determining the two processes the results also show strong persistence in the dynamics of health and labor market risks

a joint dynamic model of fertility and work of married women this article estimates a dynamic model of fertility and labor supply of married women drawn from the national longitudinal survey of young women 1968 91 it distinguishes part time and full time employment sectors which differ by pecuniary and nonpecuniary returns and transferability of human capital the model with unobserved heterogeneity in earning ability and preferences for children fits the data and produces reasonable forecasts of labor force participation in decisions the estimates unpack important features of the persistence in labor market decisions intertemporal substitution of leisure over the life cycle and the effect of work interruptions due to childbirth on lifetime utility

career interruptions and subsequent earnings a reexamination using swedish data this paper reexamines the link between career interruptions and subsequent wages using a rich new swedish dataset we are able to disaggregate time out of work into several components regressing

expectations as a source of macroeconomic persistence evidence from survey expectations in a dynamic macro model abstract embedding survey expectations in a standard dsge model helps to identify key slope parameters in standard relationships dramatically reduces the need for lagged dependent variables often motivated by price indexation and habit formation and obviates the need for autocorrelated structural shocks in the key equations formal statistical tests demonstrate that much of the persistence in aggregate data is better accounted for by slow moving expectations rather than by habits indexation and autocorrelated structural shocks

valuation of power options under heston s stochastic volatility model abstract we derive semi analytic solutions for power option prices under the heston model specifically the pricing formula is shown to be valid whenever the power of the underlying asset price has a finite moment unlike the majority of stochastic volatility models there remains a significant problem to check the existence of moments of assets prices of order higher than one fortunately the moment explosion property under the heston model is examined systematically in andersen and piterbarg 2000 incorporating with their results we present explicit formulas for moment generating function of log price and for power option prices under the circumstances when the corresponding moments are finite in case that the corresponding moment explodes we provide two numerical methods to derive prices of power put and capped power call options in spite of a simple idea numerical examples show that the approximations are extremely accurate and efficient

sticky information phillips curves european evidence we estimate the sticky information phillips curve model of mankiw and reis 2002 using survey expectations of professional forecasters from four major european economies our estimates imply that in ation expectations in france germany and the united kingdom are updated about once a year in italy about once each six months

hierarchical package bidding a paper pencil combinatorial auction we introduce a new combinatorial auction format based on a simple trans parent pricing mechanism tailored for the hierarchical package structure proposed by rothkopf pekec and harstad 1998 to avoid computational complexity this combination provides the feedback necessary for bidders in multi round auctions to discern winning bidding strategies for subsequent rounds and to coordinate re sponses to aggressive package bids the resulting mechanism is compared to two leading alternatives in a series of laboratory experiments involving varying degrees of value synergies based on these wind tunnel tests the fcc has decided to use hierarchical package bidding in the major upcoming 700mhz auction

survey measures of expected u s inflation of real interest rates and cash flows for decisions concerning investment expenditures international capital flows and exchange rate movements hinge in large part on expected real yield differentials across countries the federal reserve needs reliable measures of expected inflation to formulate and gauge the thrust of monetary policy in fact inflation expectations have become more important to the fed given the diminished stability of the link between the monetary aggregates and gdp expenditures since the early 1980s and the greater role which has been thrust upon expected real short term interest rates in the implementation of federal reserve policy the issue of rationality of inflation expectations that is the extent to which agents form expectations without making systematic mistakes in their beliefs about what inflation will be is important if inflation expectations are formed rationally labor and financial markets will strongly tend to neutralize the potential redistributive effects of inflation over time financial capital will flow efficiently within and across national borders moreover some of the stronger claims of new classical macroeconomics like the claim that only unexpected monetary policy actions will

simple solutions to the initial conditions problem in dynamic nonlinear panel data models with unobserved heterogeneity i study a simple widely applicable approach to handling the initial conditions problem in dynamic nonlinear unobserved effects models rather than attempting to obtain the joint distribution of all outcomes of the endogenous variables i propose finding the distribution conditional on the initial value and the observed history of strictly exogenous explanatory variables the approach is flexible and results in simple estimation strategies for at least three leading dynamic nonlinear models probit tobit and poisson regression i treat the general problem of estimating average partial effects and show that simple estimators exist for important special cases copyright 2005 john wiley sons ltd

fertility and female employment dynamics in europe the effect of using alternative econometric modeling assumptions we investigate the direct and long run effects of fertility on employment in europe estimating dynamic models of labor supply under different assumptions regarding the exogeneity of fertility and modeling assumptions related to initial conditions unobserved heterogeneity and serial correlation in the error terms we find overall large direct and long run effects of giving birth on employment probabilities and these effects differ considerably across countries we find that within countries the results are sensitive to the statistical assumption made on initial conditions the inclusion of serial correlation and the assumption of strict exogeneity of children however the pattern across countries is robust to these assumptions we show that such patterns are largely consistent with prevailing institutional differences related to the flexibility of the labor markets and family policies copyright 2009 john wiley sons ltd

auctions and information acquisition sealed bid or dynamic formats the value of an asset is generally not known a priori and it requires costly investments to be discovered in such contexts with endogenous information acquisition which selling procedure generates more revenues we show that dynamic formats such as ascending price or multistage auctions perform better than their static counterpart this is because dynamic formats allow bidders to observe the number of competitors left throughout the selling procedure thus even if competition appears strong ex ante it may turn out to be weak along the dynamic format thereby making the option to acquire information valuable this very possibility also induces the bidders to stay longer in the auction just to learn about the state of competition both effects boost revenues and our analysis provides a rationale for using dynamic formats rather than sealed bid ones

life cycle employment and fertility across institutional environments in this paper we formulate a dynamic utility maximization model of female labor force participation and fertility choices and estimate approximate decision rules using data on married women in italy spain and france the pattern of estimated state dependence effects across countries is consistent with aggregate patterns in part time employment and child care availability suggesting that labor market rigidities and lack of child care options are important sources of state dependence simulations of the model reveal that italian and spanish women would substantially increase their participation rates were they to face the french institutional environment

payoff assessments without probabilities a simple dynamic model of choice abstract we develop a model which reflects the tendency of people to simplify the decision problems they face the decision maker chooses among alternate strategies only on the basis of the payoff she assesses she would obtain from them and these assessments do not explicitly take into account her subjective judgements regarding the likelihood of alternate states of the world at each stage the decision maker chooses the strategy that she assesses to give the highest payoff she updates her assessments adaptively we show that such behavior leads to maxmin choices we also consider the decision maker who experiences shocks journal of economic literature classification numbers c7 d8

behavioral heterogeneity in u s inflation dynamics in this article we develop and estimate a behavioral model of inflation dynamics with heterogeneous firms in our stylized framework there are two groups of price setters fundamentalists and rando

is inflation sticky abstract new keynesian sticky price models predict that monetary policy can affect real variables however they also predict that inflation can be reduced without depressing output or employment in fact bringing down inflation is costly presenting a challenge to the new keynesian model two departures from the new keynesian model predict costly disinflation one assumes sticky inflation rather than sticky prices while the other assumes less than perfectly rational expectations taking into account information from surveys of inflation expectations i find the evidence suggests that inflation is not sticky and that inflation expectations are less than perfectly rational

separating moral hazard from adverse selection and learning in automobile insurance longitudinal evidence from france the identification of information problems in different markets is a challenging issue in the economic literature this paper performs tests of residual asymmetric information in the french automobile insurance market for the 1995 1997 period this market is characterized by the presence of a regulated experiencerating scheme bonus malus contract choices are strongly associated with the bonus malus of policyholders we have access to longitudinal survey data with dynamic information both on claims and accidents we propose a causality test to distinguish pathways through which a positive correlation arises between contract choice and accidents we find evidence of moral hazard among a sub group of policyholders with significant driving experience 5 15 years we distinguish this moral hazard estimate from adverse selection and learning policyholders with less experience have a combination of learning and moral hazard whereas no residual information problem is found for policyholders with more than 15 years of experience

when does learning in games generate convergence to nash equilibria the role of supermodularity in an experimental setting this study clarifies the conditions under which learning in games produces convergence to nash equilibria in practice previous work has identified theoretical conditions under which various stylized learning processes achieve convergence one technical condition is supermodularity which is closely related to the more familiar concept of strategic complementarities we experimentally investigate the role of supermodularity in achieving convergence through learning using a game from the literature on solutions to externalities we systematically vary a free parameter below close to at and beyond the threshold of supermodularity to assess its effects on convergence we find that supermodular and near supermodular games converge significantly better than those far below the threshold from a little below the threshold to the threshold the improvement is statistically insignificant within the class of supermodular games increasing the parameter far beyond the threshold does not significantly improve convergence simulation shows that while most experimental results persist in the long run some become more pronounced

state dependence serial correlation and heterogeneity in intertemporal labor force participation of married women a dynamic search framework is developed to analyze the intertemporal labor force participation behavior of married women using longitudinal data to allow for a rich dynamic structure the sensitivity to alternative distributional assumptions is evaluated using linear probability and probit models the dynamic probit models are estimated using maximum simulated likelihood msl estimation to overcome the computational difficulties inherent in maximum likelihood estimation of models with nontrivial error structures the results find that participation decisions are characterized by significant state dependence unobserved heterogeneity and negative serial correlation in the error component the hypothesis that fertility decisions are exogenous to women s participation decisions is rejected when dynamics are ignored however there is no evidence against this hypothesis in dynamic model specifications women s participation response is stronger to permanent than current nonlabor income reflecting unobserved taste factors

inflation expectations as a policy tool abstract we assess the prospects for central banks using inflation expectations as a policy tool for stabilization purposes we review recent work on how expectations of agents are formed and how they affect their economic decisions empirical evidence suggests that inflation expectations of households and firms affect their actions but the underlying mechanisms remain unclear especially for firms two additional limitations prevent policy makers from being able to actively manage inflation expectations first available surveys of firms expectations are systematically deficient which can only be addressed through the creation of large nationally representative surveys of firms second neither households nor firms expectations respond much to monetary policy announcements in low inflation environments we provide suggestions for how monetary policy makers could pierce this veil of inattention through new communication strategies as well as the potential pitfalls to trying to do so

ascending price vickrey auctions for general valuations ascending price auctions typically involve a single price path with buyers paying their final bid price using this traditional definition no ascending price auction can achieve the vickrey clarke groves vcg outcome for general private valuations in the combinatorial auction setting we relax this definition by allowing discounts to buyers from the final price of the auction or alternatively calculating the discounts dynamically during the auction while still maintaining a single price path using a notion called universal competitive equilibrium prices shown to be necessary and sufficient to achieve the vcg outcome using ascending price auctions we define a broad class of ascending price combinatorial auctions in which truthful bidding by buyers is an ex post nash equilibrium any auction in this class achieves the vcg outcome and ex post efficiency for general valuations we define two specific auctions in this class by generalizing two known auctions in the literature 11 24

what can survey forecasts tell us about information rigidities a lot we derive common and conflicting predictions from models in which agents face information constraints and then assess their validity using surveys of consumers firms central bankers and professional forecasters we document that mean forecasts fail to completely adjust on impact to shocks leading to statistically and economically significant deviations from the null of full information the dynamics of forecast errors after shocks are consistent with the predictions of models with information rigidities the conditional responses of forecast errors and disagreement among agents can also be used to differentiate between some of the most prominent models of information rigidities

inattentive consumers and international business cycles this paper presents and studies the properties of a sticky information exchange rate model where consumers and producers update their information sets infrequently introducing inattentive consumers has important implications through a mechanism resembling the limited participation models exchange rate volatility observed in the data can be addressed for reasonable values of risk aversion the model generates more persistence in output consumption and employment which brings us closer to the data impulse responses to monetary shocks are hump shaped consistent with the empirical evidence forecast errors of inattentive consumers provide a channel to reduce the correlation of relative consumption and real exchange rate the decline in the correlation is quantitatively small for our benchmark model model generates a substantial amount of consumer forecast errors when producers are attentive and productivity shocks are persistent this specification results in a large decline of the correlation of real exchange rate and relative consumption due to consumer inattentiveness when trade elasticity is set to values at the low end of macro estimates or at higher values consistent with sectoral estimates the correlation is in the negative territory with inattentive consumers

allocating uncertain and unresponsive resources an experimental approach we identify an important class of economic problems that arise naturally in several applications the allocation of multiple resources when there are uncertainties in demand or supply unresponsive supplies no inventories and fixed capacities and significant demand indivisibilities rigidities examples of such problems include scheduling job shops airports or supercomputers zero inventory planning and the allocation and pricing of nasa s planned space station using experimental methods we show that the two most common organizations used to deal with this problem markets and administrative procedures can perform at very low efficiencies 60 65 efficiency in a seemingly robust example thus there is a need to design new mechanisms that more efficiently allocate resources in these environments we develop and analyze two mechanisms that arise naturally from auctions used to allocate single dimensional goods these new mechanisms involve computer assisted coordination made possible by the existence of networked computers both mechanisms significantly improve on the performance of administrative and market procedures

inattentive professional forecasters abstract using the ecb survey of professional forecasters to characterize expectations at the micro level we emphasize two new facts forecasters i fail to systematically update their forecasts and ii disagree even when updating it is moreover found that forecasters have predictable forecast errors these facts are qualitatively supportive of recent models of inattention and suggest a setup where agents imperfectly process information due to both sticky information a la mankiw reis and noisy information a la sims however building and estimating such an expectation model we find that it cannot quantitatively replicate the error and disagreement observed in the data

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

new keynesian economics and the phillips curve models with sticky prices are an important part of new keynesian economics the author shows that several of the new keynesian models imply a formulation that is similar to the expectations augmented phillips curve of milton friedman and edmund phelps he then presents new estimates of the new keynesian phillips curve the author uses two proxies for price expectations survey based measures and an econometric based measure originally developed by bennett mccallum 1976 overall the results are consistent with the model but the survey based results are more precise suggesting that the surveys may be better measures of actual expectations copyright 1995 by ohio state university press

the great moderation in the united kingdom we use a bayesian time varying parameters structural var with stochastic volatility for gdp deflator inflation real gdp growth a 3 month nominal rate and the rate of growth of m4 to investigate the underlying causes of the great moderation in the united kingdom our evidence points toward a dominant role played by good luck in fostering the more stable macroeconomic environment of the last two decades results from counterfactual simulations in particular show that i bringing the monetary policy committee back in time would only have had a limited impact on the great inflation episode at the cost of lower output growth ii imposing the 1970s monetary rule over the entire sample period would have made almost no difference in terms of inflation and output growth outcomes and iii the great inflation was due to a dominant extent to large demand non policy shocks and to a lesser extent especially in 1973 and 1979 to supply shocks

common drifting volatility in large bayesian vars the general pattern of estimated volatilities of macroeconomic and financial variables is often broadly similar we propose two models in which conditional volatilities feature comovement and study them using u s macroeconomic data the first model specifies the conditional volatilities as driven by a single common unobserved factor plus an idiosyncratic component we label this model bvar with general factor stochastic volatility bvar gfsv and we show that the loss in terms of marginal likelihood from assuming a common factor for volatility is moderate the second model which we label bvar with common stochastic volatility bvar csv is a special case of the bvar gfsv in which the idiosyncratic component is eliminated and the loadings to the factor are set to 1 for all the conditional volatilities such restrictions permit a convenient kronecker structure for the posterior variance of the var coefficients which in turn permits estimating the model even with large datasets while perhaps misspecifi

on the robustness of non linear personalized price combinatorial auctions abstract though the vcg auction assumes a central place in the mechanism design literature there are a number of reasons for favoring iterative combinatorial auctions icas several promising ica formats were developed based on primal dual and subgradient algorithms prices are interpreted as a feasible dual solution and the provisional allocation is interpreted as a feasible primal solution ibundle 3 dvsv and ascending proxy auction result in vcg payoffs when the coalitional value function satisfies buyer submodularity and bidders bid straightforward which is an ex post nash equilibrium in this case ibea and creditdebit auctions do not even require the buyer submodularity and achieve the same properties for general valuations often however one cannot assume straightforward bidding and it is not clear from the theory how these non linear personalized price auctions nlppas perform in this case robustness of auctions with respect to different bidding behavior is a critical issue for any application we conducted a large number of computational experiments to analyze the performance of nlppas with respect to different bidding strategies and valuation models we compare nlppas with the vcg auction and with icas with linear prices such as alps and the combinatorial clock auction while nlppas performed very well in case of straightforward bidding we observe problems with revenue efficiency and speed of convergence when bidders deviate

multi object auctions with resale theory and experiment abstract we study multi object auctions in the presence of post auction trade opportunities among bidders who have either single or multi object demand we focus on two formats vickrey auctions where package bidding is possible and simultaneous second price auctions we show that under complementarities the vickrey format has an equilibrium where the objects are allocated efficiently at the auction stage whether resale markets are present or not the simultaneous second price on the other hand leads to inefficiency with or without resale possibility our experimental findings show that the possibility of resale in second price auctions decreases the efficiency rate at the auction stage compared to the no resale case however after resale the efficiency rate in second price is as high as that of vickrey auction without resale outcomes in the experiment preventing resale neither benefits nor hurts auction revenues in a second price format

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

ownership of stocks and mutual funds a panel data analysis this paper analyzes the ownership dynamics of stocks and mutual funds using representative household panel data the dutch center savings survey 1993 1998 a bivariate dynamic binary choice model is introduced allowing for interactions between the two types of assets we find that unobserved heterogeneity and state dependence play a large role for both types of assets the positive relation between ownership of one type in one period and the other type in the next period is explained by correlated unobserved heterogeneity a negative state dependence effect of lagged ownership of stocks on ownership of mutual funds is found which can be explained by the costs of shifting funds across the two forms of stockholding

shifting endpoints in the term structure of interest rates abstract this paper links the term structure to perceptions of monetary policy long horizon forecasts of short rates required by no arbitrage term structure models are heavily influenced by the endpoints or limiting conditional forecasts of the short rate process common assumptions that the short rate is mean reverting or contains a unit root are shown to generate unrealistic yield predictions failures occur because these assumptions inadequately account for historical shifts in market perceptions of the policy target for inflation this paper links endpoint shifts to agent learning about shifts in long term policy goals shifting endpoints in short rate processes significantly improve yield predictions

macroeconomic expectations of households and professional forecasters economists have long emphasized the importance of expectations in determining macroeconomic outcomes yet there has been almost no recent effort to model actual empirical expectations data instead m acroeconomists usually simply assume that expectations are rational this paper shows that while empirical household expectations are not rational in the usual sense expectational dynamics are well captured by a model in which households views derive from news reports of the views of professional forecasters which in turn may be rational the model s estimates imply that people only occasionally pay attention to news reports this inattention generates stickyness in aggregate expectations with important macroeconomic consequences

a new and improved design for multiobject iterative auctions in this paper we present a new improved design for multiobject auctions and report on the results of experimental tests of that design we merge the better features of two extant but very different auction processes the simultaneous multiple round smr design used by the fcc to auction the electromagnetic spectrum and the adaptive user selection mechanism ausm of banks et al 1989 allocating uncertain and unresponsive resources an experimental approach rand journal of economics vol 20 no 1 pp 1 25 then by adding one crucial new feature we are able to create a new design the resource allocation design rad auction process which performs better than both our experiments demonstrate that the rad auction achieves higher efficiencies lower bidder losses higher net revenues and faster times to completion without increasing the complexity of a bidder s problem

job search requirements for unemployed at the end of working life effects on unemployment dynamics and self employment probabilities this paper investigates the extent to which job search requirements in unemployment insurance u i increase the probability of self employment as a retirement route for causal identification we apply a difference in differences approach using a dutch 2004 policy reform that introduced job search requirements in u i for persons aged 57 5 and older unemployment dynamics and self employment probabilities are studied using a dynamic multinomial logit model with unobserved heterogeneity the results suggest that job search requirements stimulated people to exit unemployment and discouraged older workers to enter unemployment the probability of self employment as an exit route to retirement increased relative to u i but not relative to paid employment

children and household economic behavior this paper looks at some of the methodological issues that arise in modeling the effects of children on household behavior and presents some estimates for selected areas for our purposes household behavior will be taken to refer to household decisions on labor supply the allocation of expenditure to different periods and the decision as to what to do with the difference between income and expenditure i shall be concerned mainly with the effects of dependent children and i restrict attention largely to western societies excerpt

multi object auctions with package bidding an experimental comparison of vickrey and ibea abstract the use of package auctions for complex resource allocation has been rapidly increasing in recent years in this paper we study two package auction mechanisms in a laboratory setting a sealed bid vickrey auction and an ascending version of vickrey the i bea auction unlike the single unit vickrey auction where bidders tend to overbid in the laboratory most of our bidders either underbid or bid their true values furthermore at the aggregate level while the vickrey auction generates significantly higher revenue than does i bea the i bea auction generates significantly higher bidder profit and efficiency additionally a significantly larger proportion of i bea auctions achieves 100 efficiency than does the vickrey auction we also find that human bidders learn from their robot opponents when the robot strategies are myopic best responses

raising female employment reflections and policy tools while there is consensus on the need to raise the time spent in the market by european women it is not clear how these goals should be achieved tax wedges assistance in the job search process and part time jobs are policy instruments that are widely debated in policy circles the paper presents a simple model of labor supply with market frictions and heterogenous home production where the effects of these policies can be coherently analyzed we show that subsidies to labor market entry increase women s entrance in the labor market but they also increase exits from the labor market with ambiguous effect on employment subsidies to part time do increase employment but they have ambiguous effects on hours and market production finally reductions in taxes on market activities that are highly substitutable with home production have unambiguous positive effects on market employment and production jel j0 j2

theoretical and experimental investigations of the performance of keyword auction mechanisms two keyword auction mechanisms the generalized second price auction gsp and the vickrey clarke groves mechanism vcg were compared theoretically and experimentally the former is widely used in practice the latter is not but it has a dominant strategy equilibrium where all participants bid their true values in the theoretical investigation by applying the locally envy free nash equilibrium to the vcg we found that the allocations are efficient and that upper and lower bounds of the auctioneer s revenue coincide in the two mechanisms a laboratory experiment in which the revenues and efficiencies were similar in both mechanisms supported this result

children and their parents labor supply evidence from exogenous variation in family size although theoretical models of labor supply and the family are well developed there are few credible estimates of key empirical relationships in the work family nexus this study uses a new instrumental variable the sex composition of the first two births in families with at least two children to estimate the effect of additional children on parents labor supply in the united states instrumental variables estimates using the sex mix are substantial but smaller than the corresponding ordinary least squares ols estimates moreover unlike the ols estimates the female labor supply effects estimated using sex mix instruments appear to be absent among more educated women and women with high wage husbands we also find that married women who have a third child reduce their labor supply by as much as women in the full sample while there is no relationship between wives child bearing and husbands labor supply excerpt

the structural dynamics of output growth and inflation some international evidence we examine the dynamics of output growth and inflation in the us euro area and uk using a structural time varying coefficient var there are important similarities in structural inflation dynamics across countries output growth dynamics differ swings in the magnitude of inflation and output growth volatilities and persistences are accounted for by a combination of three structural shocks changes over time in the structure of the economy are limited and permanent variations largely absent changes in the volatilities of structural shocks matter

evolving u s monetary policy and the decline of inflation predictability based on a structural var with time varying parameters and stochastic volatility for the post wwii u s we document a negative correlation between the evolution of the long run coefficient on inflation in the structural monetary rule and the evolution of the persistence and predictability of inflation relative to a trend component using an estimated sticky price model we show that a more aggressive policy stance towards inflation causes a decline in inflation predictability jel e37 e52 e58

estimating welfare effects consistent with forward looking behavior part ii empirical results in this paper we provide estimates of welfare benefit effects on a set of behaviors that includes welfare participation fertility marriage work and schooling using approximations to the decision rules that would be derived from an explicit dynamic optimization problem we use the stylized model and associated simulations from part i as a guide in specifying the approximate decision rules that we estimate here the estimates are based on data from the 1979 youth cohort of the national longitudinal surveys of labor market experience nlsy79

experimental evidence on inflation expectation formation using laboratory experiments within a new keynesian sticky price framework we study the process of inflation expectation formation we focus on adaptive learning and rational expectations contrary to the previous literature that mostly studied simple heuristics using a test for rational expectations that allows heterogeneity of expectations we find that we cannot reject rationality for about 40 of subjects more than 20 of subjects are also best described by adaptive learning models where they behave like econometricians and update their model estimates every period however rather than using a single forecasting model switching between models describes their behavior better switching is more likely to occur when experimental economy is in a recession

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

fitting observed inflation expectations abstract the paper provides evidence on the extent to which inflation expectations generated by a standard christiano et al 2005 smets and wouters 2003 type dsge model are in line with what observed in the data we consider three variants of this model that differ in terms of the behavior of and the public s information on the central banks inflation target allegedly a key determinant of inflation expectations we find that i time variation in the inflation target is needed to capture the evolution of expectations during the post volcker period ii the variant where agents have imperfect information is strongly rejected by the data iii inflation expectations appear to contain information that is not present in the other series used in estimation and iv none of the models fully capture the dynamics of this variable

the structure of expectations of the weekly money supply announcement abstract this paper examines the structure of expectations of the weekly money supply announcement in the late 1970s the data used are from a weekly telephone survey of money market participants the rationality and structure of expectations are explored with the data organized in three ways the mean response to each weekly survey the pooled sample of individual responses and time series of responses by each individual in the survey the effect of data aggregation on rationality tests is investigated the structure of the expectations data are also examined and it is found that both strong regressive influences and adaptive learning characterize the data

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

a framework for estimating dynamic unobserved effects panel data models with possible feedback to future explanatory variables abstract i show how to construct the likelihood function for the conditional maximum likelihood estimator in dynamic unobserved effects models where not all conditioning variables are strictly exogenous the method for handling the initial conditions problem appears to be novel and offers a flexible relatively simple alternative to existing methods

information induced heteroscedasticity in price expectations data this study tests the hypothesis that price expectations differ across individuals because they acquire different information about inflation if price information is a normal good then the amount of price information acquired will vary across individuals according to income education and other demand specific variables causing price expectations to be heteroscedastic with respect to these variables utilizing monthly household survey data the authors test the heteroscedasticity hypothesis and find support for the differential information model in addition they develop a novel method of incorporating the don t know response to questions about inflation into the estimation of price expectations copyright 1990 by mit press

implications of rational inattention abstract a constraint that actions can depend on observations only through a communication channel with finite shannon capacity is shown to be able to play a role very similar to that of a signal extraction problem or an adjustment cost in standard control problems the resulting theory looks enough like familiar dynamic rational expectations theories to suggest that it might be useful and practical while the implications for policy are different enough to be interesting

binary choice with binary endogenous regressors in panel data this article considers the estimation of the causal effect of fertility on female labor force participation equations my main concern is to examine two considerations the endogeneity of fertility and the impact of controlling for unobserved heterogeneity and for predetermined existing children using psid data a switching binary panel data model that accounts for selectivity bias as well as for other forms of time invariant unobserved heterogeneity is estimated individual effects are allowed to be correlated with the explanatory variables which can be predetermined as opposed to strictly exogenous family sex composition is used as an instrument for exogenous fertility movements the results indicate that exogeneity assumptions of children variables induce a downward bias in absolute value in the estimated negative effect of fertility on participation although the failure to account for unobserved heterogeneity overstates this effect moreover stronger effects of fertility are found when existing c

vickrey auctions in practice from nineteenth century philately to twenty first century e commerce william vickrey 1961 proposed an auction mechanism in which bidders submit sealed bids and the highest bidder wins the good in return for payment of the second highest bid amount for decades economists have credited vickrey with inventing this auction format and have believed that the vickrey auction is rarely used in practice this paper presents evidence that vickrey auctions have long been the predominant auction format for mail sales of collectible postage stamps stamp auctioneers developed this auction format on their own as early as 1893 even before vickrey was born

models of inflation expectations formation a comparison of household and economist forecasts comment in the third section of his paper models of inflation expectations formation a comparison of household and economist forecasts gramlich 1983 presents statistics suggesting that two survey measures of inflation expectations are biased and inefficient in this comment we show that the main results presented in his table 1 are generated using a misspecified model when the specification error is corrected we find that the michigan survey of household inflation expectations passes the standard tests for unbiasedness and weak tests for efficiency 1 however there remains doubt about the properties of the inflation expectation series derived from the livingston survey of professional economists 2 the particular results we review were presumably generated from ordinary leastsquares ols estimation of the following equation equation 2 in gramlich
