a reevaluation of the macroeconomic effects of positive trend inflation abstract to date most of the papers which have examined the effects of trend inflation on the properties of new keynesian model were based on relatively simple sticky prices dsge models and whose realism was sometimes questionable in this paper we re evaluate the macroeconomic effects of non zero trend inflation building on the model of ascari 2004 as one of the most cited papers in the literature on the effects of trend inflation we show that the omission of some important theoretical ingredients significantly distorts the results obtained to date we propose a refinement of this model by introducing two theoretical important ingredients namely investment adjustment costs and a roundabout production structure once we add these features to make the model more realistic as commonly for medium scale models we find that the standard new keynesian model without real frictions overestimates the short term macroeconomic effects of a positive trend inflation rate and underestimates those of the long term

the inflation tax in a real business cycle model money is incorporated into a real business cycle model using a cash in advance constraint the model economy is used to analyze whether the business cycle is different in high inflation and low inflation economies and to analyze the impact of variability in the growth rate of money in addition the welfare cost of the inflation tax is measured and the steady state properties of high and low inflation economies are compared

the excess demand for subsidized child care in germany the extension of publicly provided or subsidized child care is currently one of the priorities of the political agenda in many european countries in this article the excess demand for subsidized child care slots in germany is estimated using a partial observability model the results show that there is considerable excess demand for child care for children aged less than 3 years in east and west germany even among children with working mothers

a quantitative theory of the gender gap in wages abstract this paper measures how much of the gender wage gap over the life cycle is due to the fact that working hours are lower for women than for men we build a quantitative theory of fertility labor supply and human capital accumulation decisions to measure gender differences in human capital investments over the life cycle we assume that there are no gender differences in the human capital technology and calibrate this technology using wage age profiles of men the calibration of females assumes that children involves a forced reduction in hours of work that falls on females rather than on males and that there is an exogenous gender gap in hours of work we find that our theory accounts for all of the increase in the gender wage gap over the life cycle in the nlsy79 data the impact of children on the labor supply of females accounts for 56 and 45 of the increase in the gender wage gap over the life cycle among non college and college females while the rest is due to the exogenous gender differences in hours of work

the political economy of publicly provided private goods abstract this paper integrates two different approaches to the analysis of public provision of private goods education health care day care etc while normative public economics has established an efficiency case for such provision the commonly held political economy view has been that it is an economically inefficient phenomenon generated by the political process we establish a political economy framework which in general yields an efficient choice of distributional policy it follows that the central mechanism studied in the normative theory is equally relevant to voting models of decisions on public provision it is shown that under plausible information constraints economically efficient public provision of private goods will be part of politically rational decisions the result is established both within a median voter process and a representative democracy of political parties

taxation and household labor supply we evaluate reforms to the u s tax system in a life cycle setup with heterogeneous married and single households and with an operative extensive margin in labor supply we restrict our model with observations on gender and skill premia labor force participation of married females across skill groups children and the structure of marital sorting we concentrate on two revenue neutral tax reforms a proportional income tax and a reform in which married individuals flle taxes separately separate flling our flndings indicate that tax reforms are accompanied by large increases in labor supply that difier across demographic groups with the bulk of the increase coming from married females under a proportional income tax reform married females account for more than 50 of the changes in hours across steady states while under separate flling reform married females account for all the change in hours

child care and the labor supply of married women reduced form evidence this paper empirically analyzes family demands for market and nonmarket child care services and the impact of these demands on the work effort of married women the paperfirst develops a general model of child care and labor force participation the model predicts that higher wages increase the likelihood of labor force participation and that higher costs decrease the likelihood of child care utilization the paper then develops a threeequation reduced form econometric specification of the general model the equations in the specification are estimated simultaneously using 1985 data from the survey of income program participation the estimates reveal that the cost of market child care has a strong negative effect on the labor supply of married women

tax effects versus budget effects on labor supply this paper analyzes the effects on labor supply of parallel changes in taxes and public spending of various types a number of important recent developments in the labor supply behavior of households are highlighted by such a study of various types of budget effects rather than isolated tax effects this comes out in particular when considering cross substitution effects on labor supply of changes in public spending on goods and services or of the subsidization of goods and services provided by private markets moreover the income effects of tax changes are often mitigated or possibly even removed by the income effects of the accompanying expenditure changes

an empirical model of labor supply in a life cycle setting this paper formulates and estimates a structural intertemporal model of labor supply using theoretical characterizations derived from an economic model of lifetime behavior a two step empirical analysis yields estimates of intertemporal and uncompensated substitution effects which provide the information needed to predict the response of hours of work to life cycle wage growth and shifts in the lifetime wage path

seasonal solow residuals and christmas a case for labor hoarding and increasing returns in aggregate unadjusted data measured solow residuals exhibit large seasonal variations total factor productivity grows rapidly in the fourth quarter at an annual rate of 16 percent and regresses sharply in the first quarter at an annual rate of 24 percent how much of the total seasonal variation in the measured solow residual can be explained by christmas the answer to this question is surprising with increasing returns and time varying labor effort christmas is sufficient to explain the seasonal variation in the solow residual consumption average productivity and output in all four quarters our analysis of seasonally unadjusted data uncovers important roles for labor hoarding and increasing returns that are difficult to identify in adjusted data prescott 1986 has argued that the variability of solow s residual is a reasonable estimate of the variability of exogenous technology shocks when solow s residual is measured using seasonally unadjusted data for the postwar u s economy it exhibits large seasonal variations growing rapidly in the fourth quarter at an annual rate of 16 percent and falling sharply in the first quarter at an annual rate of 24 percent this paper starts from the premise that it is implausible to attribute seasonal variation of this magnitude to changes in the state of technology we present a model in which all seasonal fluctuations arise from a single demand shift christmas this demand shift together with misspecification of the traditional production function leads to large seasonal variation in the solow residual we consider two candidates for misspecification labor hoarding and external increasing returns to scale even when technological growth is aseasonal either candidate in isolation can induce spurious seasonality in the solow residual our general equilibrium analysis indicates that 1 the economy s seasonal patterns in all four quarters may be a response simply to a fourth quarter consumption demand shift and 2 a combination of labor hoarding and external increasing returns is important for replicating these patterns in aggregate quantity variables for the postwar u s economy since our analysis identifies important roles for labor hoarding and increasing returns these results have implications for nonseasonal macroeconomic models indeed our analysis im

nominal price rigidity money supply endogeneity and business cycles abstract this paper investigates the ability of nominal price rigidity to explain the co movement of inflation with the cyclical component of output observed in the post war u s data a dynamic general equilibrium model is constructed with the introduction of monopolistic competition and nominal price rigidity in a standard real business cycle model allowing for an endogenous money supply rule it is then demonstrated that sticky price models can explain the observed associations between movements in inflation and output much better than flexible price models this result depends little on whether money supply is assumed to be endogenous or not

lack of divine coincidence in new keynesian models abstract the literature has long agreed that the divine coincidence holds in standard new keynesian models the monetary authority is able to simultaneously stabilize inflation and output gap in response to preference and technology shocks i show that the divine coincidence holds only when inflation is stabilized at exactly zero even small deviations from zero generate policy trade offs i demonstrate this result using the model s non linear equilibrium conditions to avoid biases from log linearization when the model is log linearized a non zero steady state level of inflation gives rise to what i call the endogenous trend inflation cost push shock in the new keynesian phillips curve

optimal taxation in life cycle economies abstract we use a very standard life cycle growth model in which individuals have a labor leisure choice in each period of their lives to prove that an optimizing government will almost always find it optimal to tax or subsidize interest income the intuition for our result is straightforward in a life cycle model the individual s optimal consumption work plan is almost never constant and an optimizing government almost always taxes consumption goods and labor earnings at different rates over an individual s lifetime one way to achieve this goal is to use capital and labor income taxes that vary with age if tax rates cannot be conditioned on age a nonzero tax on capital income is also optimal as it can imperfectly mimic age conditioned consumption and labor income tax rates journal of economic literature classification numbers e62 h21

another look at long run money demand abstract this paper investigates the long run demand for m1 in the postwar united states previous studies based on data ending in the late 1980s are inconclusive about the parameters of postwar money demand this paper obtains precise estimates of these parameters by extending the data through 1996 the income elasticity of money demand is approximately 0 5 and the interest semi elasticity is approximately 0 05 these parameters are significantly smaller in absolute value than the corresponding parameters for the prewar period a caveat is that the analysis assumes there is no trend in money demand resulting from technological change

taxes and marriage a two sided search analysis this article analyzes the effects of differential tax treatment of married and single individuals in the united states on marriage formation and composition divorce and labor supply we develop a marriage market model with search frictions and heterogeneous agents that is sufficiently rich to capture key elements of the problem under consideration we then calibrate the model and use it to evaluate the quantitative effects of several tax reforms aimed at making the tax law neutral with respect to marital status we find that these reforms i systematically increase the labor supply of married females with changes ranging from 0 3 to 10 1 percent ii have substantial effects on the correlation of spouses incomes which changes from 0 2 to values between 0 185 and 0 334 iii can lead to either an increase or decrease in the fraction of people married with changes that range from 0 6 to 2 4 percent

inflation targeting and relative price variability what difference does inflation targeting make author affiliation chi young choi cychoi uta eduyoung se kim acknowledgment the authors are grateful to coeditor kent kimbrough and two anonymous referees for constructive comments that helped to improve this article the authors also wish to thank steve cecchetti kang liu shin ichi nishiyama margie tieslau taka tsuruga and the seminar participants at the academia sinica national chung cheng university national sun yat sen university national taiwan university texas tech university and the university of texas at arlington for helpful comments and vikas kakkar for providing cpi data for hong kong any remaining errors are the authors 1 introductionvariability in relative prices is known to be a major channel through which inflation can induce welfare costs by impeding an efficient allocation of resources in the economy consequently substantial effort has been devoted in the literature to examining the link between relative price variability rpv and aggregate inflation although much of the existing theoretical and empirical literature points to a positive monotonic relationship newer contributions suggest that the relationship between inflation and rpv is more complicated particularly in terms of its sensitivity to the inflation regime 1the primary purpose of this study is to investigate whether the connection between inflation and rpv is influenced in an important way by the monetary policy framework chosen by a central bank specifically this article focuses on exploring whether the adoption of an inflation targeting it framework exerts any significant impact on rpv as measured by the standard deviations of sectoral inflation rates relative to the aggregate rate since it was first implemented in new zealand more than two decades ago the popularity of it has spread with some twenty five countries worldwide implementing the framework to date freedman and laxton 2009 the literature is now replete with studies pointing to reductions in both the level and the volatility of inflation in countries that have adopted it e g mishkin and schmidt hebbel 2007 2 while studies of the impact of it on aggregate inflation performance are plentiful little attention has been paid to the impact of it on rpv the question of whether and indeed how it affects rpv is an important one for several reasons first exploring the potential connection between it and rpv is a worthwhile exercise given the popularity of it as a monetary framework and the centrality of rpv to the current generation of macromodels the importance of rpv is recognized in standard new keynesian dynamic stochastic general equilibrium dsge models where the variance of relative prices is viewed as a useful summary statistic as noted by amano ambler and rebei 2007 for example in dsge models the optimal rate of target inflation and the optimal variability of inflation relative to output depend on the quantitative effects of price dispersion on macroeconomic equilibrium second answering the question helps us identify the driving force behind the change in rpv distinguishing between it adoption itself and its subsequent impact on inflation if the relationship is monotonically positive as is often believed in the literature one should expect that it adoption would bring about a decline in rpv in the same way as it has led to a decline in inflation if the relationship is more complex however the effect of it adoption on reducing rpv may hinge on the change in inflation regimes after it adoption third our answer to the question also sheds additional light on the empirical evidence for the relative effectiveness of it across different stages of development while there is strong evidence that developing countries benefit more from it than industrial countries in combating inflation and its volatility e g petursson 2004 lin and ye 2009 we are aware of no empirical research that has assessed this issue with respect to rpv

on the welfare and cyclical implications of moderate trend inflation abstract the welfare and cyclical implications of moderate trend inflation are addressed in an augmented medium scale dsge model increasing trend inflation from 2 to 4 percent generates a consumption equivalent welfare loss of about 4 percent welfare costs of this magnitude are driven by staggered wage contracts trend growth extended borrowing a roundabout production structure and the interaction between trend inflation and shocks to the marginal efficiency of investment mei a sticky price model abstracting from these features generates much smaller losses moderate trend inflation also has important business cycle implications interacting much more strongly with mei shocks than with productivity or monetary shocks

trend inflation taylor principle and indeterminacy positive trend inflation shrinks the determinacy region of a basic new keynesian dynamic stochastic general equilibrium model when monetary policy is conducted by a contemporaneous interest rate rule neither the taylor principle which requires the inflation coefficient to be greater than one nor the generalized taylor principle which requires that the nominal interest rate to be raised by more than the increase in inflation in the long run is a sufficient condition for local determinacy of equilibrium this finding holds for different types of taylor rules inertial policy rules and price indexation schemes therefore regardless of the theoretical setup the monetary literature on interest rate rules cannot disregard average inflation in both theoretical and empirical analyses

the politics of public provision of education public provision of education is usually viewed as a form of redistribution in kind however does it arise when income redistribution is feasible as well i analyze a two dimensional model of political decision making with endogenous political parties society chooses both the tax rate and the allocation of the revenues between income redistribution and public education agents differ in their income and in their age where young agents prefer public education and the old prefer income redistribution i find that when the cohort size of the young is not too large then public education arises as a political compromise between the rich and the young segment of the poor they collude in order to reduce the size of government which benefits the rich and target some of its resources to education which benefits the young poor when the cohort size of the young is too large however income redistribution crowds out public provision of education in the political equilibrium

public control of rational and unpredictable epidemics abstract efforts to improve disease forecasting are often justified on the grounds that accurate and reliable forecasts offer opportunities to improve response to epidemics yet little is known about how disease forecasts influence the responsiveness to public health interventions this paper couples an optimal stopping model and rational disease prevention with a stochastic compartmental epidemiological model of disease spread to develop a framework for evaluating the timing of public health interventions in response to rational but unpredictable epidemics optimal behavior by a public health agency is characterized by a pair of critical prevalence thresholds that trigger implementation and suspension of a public prevention program unlike existing economic thresholds for disease prevention our decision thresholds account for time varying probabilities of different levels of infection prevention by private individuals and the likelihood of crossing epidemiological thresholds that determine disease persistence

engines of liberation electricity was born at the dawn of the last century households were inundated with a flood of new consumer durables what was the impact of this consumer durable goods revolution it is argued here that the consumer goods revolution was conducive to liberating women from the home to analyse this hypothesis a beckerian model of household production is developed households must decide whether or not to adopt the new technologies and whether a married woman should work can such a model help to explain the rise in married female labour force participation that occurred in the last century yes the housewife of the future will be neither a slave to servants nor herself a drudge she will give less attention to the home because the home will need less she will be rather a domestic engineer than a domestic labourer with the greatest of all handmaidens electricity at her service this and other mechanical forces will so revolutionize the woman s world that a large portion of the aggregate of woman s energy will be conserved for use in broader more constructive fields thomas alva edison as interviewed in good housekeeping magazine lv no 4 october 1912 p 436

education spending in an aging america abstract in this paper we use a national panel of public school districts to study the impact of an aging population on public education spending in contrast to previous analyses that use state level data we find that the elderly have only a modest overall negative effect on education spending at the district level our results confirm however that a growing share of elderly at the state level tends to depress state spending on education these results are consistent with the hypothesis that the elderly believe only higher local spending is capitalized into house values

the impact of child care costs on the labour supply of married mothers evidence from canada this paper provides estimates for canada of the impact of childcare costs on the labor supply of married mothers this is done by linking two microdata sources the 1988 canadian national child care survey and the 1988 labour market activity survey the key results show that the market wage and childcare costs have respectively a significant positive and negative impact on both hours of work and the labor force participation decision by married mothers the childcare cost elasticities for labor force participation and hours of work are reported to be 0 38 and 0 32 respectively

evaluating long term care policy options taking the family seriously we propose a dynamic non cooperative framework for long term care ltc decisions of families and use it to evaluate ltc policy options for the u s we first document the importance of informal caregiving and economic determinants of care arrangements we then build a heterogeneous agents model with imperfectly altruistic overlapping generations to account for the patterns we find a key innovation is the availability of informal care ic which is determined through intra family bargaining this opens up a new margin in response to policy and allows for informal insurance through home production of care our calibrated model captures the observed care arrangements well we study the implications of non means tested ic and formal care fc subsidies as well as changes to means tested medicaid we find that ic responds strongly to these policies an ic subsidy substantially reduces reliance on medicaid while the reduction of tax revenues due to lower labour supply by caregivers is modest there are large welfare gains from a combination of ic and fc subsidies even when combined with a reduction of the medicaid program

endogenous price stickiness trend inflation and macroeconomic stability previous studies show that higher trend inflation is more likely to induce indeterminacy of equilibrium in sticky price models based on micro evidence that each period a fraction of prices is kept unchanged this paper demonstrates that when the degree of price stickiness is endogenously determined in a calvo model indeterminacy caused by higher trend inflation is less likely a key factor for determinacy is the long run inflation elasticity of output implied by the new keynesian phillips curve this elasticity declines substantially with higher trend inflation in the case of exogenously given price stickiness whereas in the case of endogenous price stickiness the decline in the elasticity is mitigated because higher trend inflation leads to a higher probability of price adjustment

child related transfers household labour supply and welfare what are the macroeconomic effects of transfers to households with children how do alternative policies fare in welfare terms we answer these questions in an equilibrium life cycle model with household labour supply decisions skill losses of females associated to non participation and heterogeneity in terms of fertility childcare expenditures and access to informal care calibrating our model to the u s economy we first provide a roadmap for policy evaluation by contrasting transfers that are conditional on market work childcare subsidies and childcare credits with those that are not child credits when both types can be means tested or universal we then evaluate expansions of current arrangements for the u s and find that expansions of conditional transfers have substantial positive effects on female labour supply that are largest at the bottom of the skill distribution expanding childcare credits leads to long run increases in the participation of married females of 10 6 while an equivalent expansion of child credits leads to the opposite 2 4 expanding existing programs generates substantial welfare gains for newborn households which are largest for less skilled households expanding childcare credits leads to the largest welfare gains for newborns and achieves majority support

labor income taxation human capital and growth the role of childcare in this paper we examine the effects of labor income taxation on growth in an overlapping generations model in which schooling and childcare play a role in the production of human capital we compare such effects with those obtained in a model in which only schooling matters for skill formation we show that the omission of childcare from the technology of skill formation can bias the results related to the impact of labor income taxation on growth

revisiting the effect of household size on consumption over the life cycle abstract although the link between household size and consumption has strong empirical support there is no consistent way in which demographics are dealt with in standard life cycle models we study the relationship between the predictions of the single agent model the standard in the literature versus a simple model extension the demographics model where deterministic changes in household size and composition affect optimal consumption decisions we show theoretically that the demographics model is conceptually preferable to the single agent model as it captures economic mechanisms ignored by the latter however our quantitative analysis demonstrates that differences in predictions for consumption are negligible across models when using standard calibration strategies this suggests that it is largely irrelevant which model specification is used

optimal fiscal and monetary policy in an economy without capital abstract this paper is concerned with the structure and time consistency of optimal fiscal and monetary policy in an economy without capital in a dynamic context optimal taxation means distributing tax distortions over time in a welfare maximizing way for a barter economy our main finding is that with debt commitments of sufficiently rich maturity structure an optimal policy if one exists is time consistent in a monetary economy the idea of optimal taxation must be broadened to include an inflation tax and we find that time consistency does not carry over an optimal inflation tax requires commitment by rules in a sense that has no counterpart in the dynamic theory of ordinary excise taxes the reason time consistency fails in a monetary economy is that nominal assets should from a welfare maximizing point of view always be taxed away via an immediate inflation in a kind of capital levy this emerges as a new possibility when money is introduced into an economy without capital

the quantitative role of child care for female labor force participation and fertility consistent with facts for a cross section of oecd countries i document that the labor force participation rate of west german mothers with children aged zero to two exceeds the corresponding child care enrollment rate whereas the opposite is true for mothers with children aged three to mandatory school age i develop a life cycle model that explicitly accounts for this age dependent relationship through various types of non paid and paid child care the calibrated version of the model is used to evaluate two policy reforms concerning the supply of subsidized child care for children aged zero to two these counterfactual policy experiments suggest that the lack of subsidized child care constitutes indeed for some females a barrier to participate in the labor market and depresses fertility

why do europeans work so little market work per person is roughly 10 higher in the united states than in sweden however if we include the work carried out in home production the total amount of work only differs by 1 i set up a model and show that differences in policy mainly taxes can account for the discrepancy in both labor supply and home production between sweden and the united states these results are independent of the elasticity of labor supply

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

trend inflation and firms price setting rotemberg versus calvo we compare the calvo and rotemberg price setting mechanisms in a new keynesian model with trend inflation we show that the long run relationship between inflation and output is positive in rotemberg and negative in calvo the dynamics of the two models differ even to a first order approximation positive trend inflation enlarges the determinacy region in the rotemberg model whereas it shrinks it in the calvo model the responses of output and inflation to technology shocks are amplified by trend inflation in calvo whereas they are dampened in rotemberg the two models imply differing non linear adjustments after a disinflation

non cognitive child outcomes and universal high quality child care exploiting a rich panel data child survey merged with administrative records along with a pseudo experiment generating variation in the take up of pre school across municipalities we provide evidence of the effects on non cognitive child outcomes of participating in large scale publicly provided universal pre school programs and family day care vis a vis home care we find that compared to home care being enrolled in pre school at age three does not lead to significant differences in child outcomes at age seven no matter the gender or mother s level of education family day care on the other hand seems to significantly deteriorate outcomes for boys whose mothers have a lower level of education finally increasing hours in family day care from 30 40 hours per week to 40 50 hours per week and hours in pre school from 20 30 hours per week to 30 40 hours per week leads to significantly poorer child outcomes

monopolistic competition and the effects of aggregate demand how important is monopolistic competition to an understanding of the effects of aggregate demand on output we ask the question at three levels can monopolistic competition by itself explain why aggregate demand movements affect output can it together with other imperfections generate effects of aggregate demand in a way that perfect competition cannot if so can it give an accurate account of the response of the economy to aggregate demand movements the answers are no yes and yes

anticipated and unanticipated wage changes wage risk and intertemporal labor supply in this article i estimate how labor supply responds to anticipated wage growth unanticipated wage growth and wage risk using the 1989 93 panel section of the bank of italy survey of households income and wealth shiw which collects individual expectations of future wages the use of subjective expectations has several advantages first they provide information on the evolution and riskiness of future wages that the econometrician may never hope to observe moreover this avoids the need for specifying instruments for the growth rate of wages finally forecast errors can be directly controlled for thus avoiding inconsistency in short panels

altruism the samaritan s dilemma and government transfer policy this paper shows that altruism provides an efficiency rationale for public provision of insurance to the poor the framework is one in which there are rich altruists and risk averse poor who face some possibility of loss the government represents the rich and makes transfers on their behalf with unconditional transfers the poor may forgo insurance and rely on private charity to bail them out in the event of loss this reliance on private charity has adverse efficiency effects these may be avoided if the government makes in kind transfers of insurance copyright 1995 by american economic association

the macroeconomic effects of nonzero trend inflation we study the macroeconomic effects of nonzero trend inflation in a simple dynamic stochastic general equilibrium model under three common time dependent pricing schemes calvo truncated calvo and taylor we show that regardless of the pricing mechanism trend inflation leads to a reduction in the stochastic means of output consumption and employment and an increase in the stochastic mean of inflation beyond its deterministic steady state level the variability of most aggregates also increases these effects are quantitatively much stronger with calvo pricing

monetary policy trend inflation and unemployment volatility the literature has long agreed that the dmp model after diamond 1982 mortensen 1982 pissarides 1985 with search and matching frictions in the labor market can deliver large volatilities in labor market quantities consistent with empirical data only if there is at least some wage stickiness i show however that the model can deliver nontrivial volatilities without wage stickiness as long as it has price dispersion and nonzero long run inflation rates i find that by keeping inflation at a positive rate monetary policy may be accountable for the large standard deviations observed on labor market variables in addition the shimer 2005 puzzle disappears under monetary policy shocks

taxation and labor supply of married couples across countries a macroeconomic analysis we document contemporaneous dierences in the aggregate labor supply of married couples across 18 oecd countries relative to their us counterparts european married men work on average 9 to 17 percent and married women in western and southern europe 26 and 31 percent fewer hours married women in scandinavia and eastern europe however work almost as many hours as us married women we nd that a model of joint household decision making can largely replicate these facts if the full non linearity of labor income taxes and the tax treatment of married couples are taken into account going to a system of strictly separate taxation would increase labor supply of married women by more than 100 hours annually in a third of our sample countries

majority rule and the public provision of a private good this paper extends the literature on the socialization of commodities by developing a model of voting over the public provision of a private good health care

public provision of private goods government may provide a good that can if legally permitted be supplemented by private purchases policy is determined by majority rule under standard assumptions on preferences a majority voting equilibrium exists a regime of positive government provision with no restriction on private supplements is shown to be majority preferred to a regime of either only market provision or only government provision combined public and private expenditure on the good is higher under this dual provision regime than under either of the alternatives under some preference configurations the median income voter is pivotal under others a voter with income below the median is pivotal

more power to the pill the impact of contraceptive freedom on women s life cycle labor supply the release of enovid in 1960 the first birth control pill afforded u s women unprecedented freedom to plan childbearing and their careers this paper uses plausibly exogenous variation in state consent laws to evaluate the causal impact of the pill on the timing of first births and extent and intensity of women s labor force participation the results suggest that legal access to the pill before age 21 significantly reduced the likelihood of a first birth before age 22 increased the number of women in the paid labor force and raised the number of annual hours worked

relative price distortions and inflation persistence sticky price models often suggest that relative price distortion is a major cost of inflation we provide an intuition for this even at low rates inflation strongly affects price dispersion which in turn has an impact on the economy qualitatively similar to and of the order of magnitude of a negative shift in productivity the utility cost of price dispersion is quantified and its impact on optimal monetary policy discussed price dispersion is incorporated into a linearised model strikingly a contractionary nominal shock has a persistent negative hump shaped impact on inflation but may have a positive hump shaped impact on output

evaluating the employment impact of a mandatory job search program this paper exploits area based piloting and age related eligibility rules to identify treatment effects of a labor market program the new deal for young people in the u k a central focus is on substitution displacement effects and on equilibrium wage effects the program includes extensive job assistance and wage subsidies to employers we find that the impact of the program significantly raised transitions to employment by about 5 percentage points the impact is robust to a wide variety of nonexperimental estimators however we present some evidence that this effect may not be as large in the longer run jel j18 j23 j38

the macroeconomics of trend inflation most macroeconomic models for monetary policy analysis are approximated around a zero inflation steady state but most central banks target an inflation rate of about 2 percent many economists have recently proposed even higher inflation targets to reduce the incidence of the zero lower bound constraint on monetary policy in this survey we show that the conduct of monetary policy should be analyzed by appropriately accounting for the positive trend inflation targeted by policymakers we first review empirical research on the evolution and dynamics of u s trend inflation and some proposed new measures to assess the volatility and persistence of trend based inflation gaps we then construct a generalized new keynesian model that accounts for a positive trend inflation in this model an increase in trend inflation is associated with a more volatile and unstable economy and tends to destabilize inflation expectations this analysis offers a note of caution regarding recent proposals to address the existing zero lower bound problem by raising the long run inflation target jel e12 e31 e32 e52 e58

optimal monetary policy under low trend inflation abstract in the monetary policy literature it is common to assume that trend inflation is zero despite overwhelming evidence that zero inflation is neither empirically relevant nor a practical objective for central bank policy we therefore extend the standard new keynesian model to allow for positive trend inflation showing that even low trend inflation has strong effects on optimal monetary policy and the dynamics of inflation output and interest rates under discretion the efficient policy deteriorates and there is no guarantee of determinacy even with commitment targeting non zero trend inflation leads to substantial welfare losses our results serve as a warning against indiscriminate use of models assuming zero trend inflation

stabilisation policy rational expectations and price level versus inflation targeting a survey we survey literature comparing inflation targeting it and price level targeting pt as macroeconomic stabilisation policies our focus is on new keynesian models and areas that have seen significant developments since ambler s 2009 price level targeting and stabilisation policy a survey journal of economic surveys 23 5 974 997 survey optimal monetary policy the zero lower bound financial frictions and transition costs of adopting a pt regime ambler s conclusion that pt improves social welfare in new keynesian models is fairly robust but we note an interesting split in the literature pt consistently outperforms it in models where policymakers commit to simple taylor type rules but results in favour of pt when policymakers minimise loss functions are overturned with small deviations from the baseline model since the beneficial effects of pt appear to hang on the joint assumption that agents are rational and the economy new keynesian we discuss survey and experimental evidence on rational expectations and the applied macro literature on the empirical performance of new keynesian models overall the evidence is not clear cut but we note that new keynesian models can pass formal statistical tests against macro data and that models with rational expectations outperform those with behavioural expectations i e heuristics in direct statistical tests we therefore argue that policymakers should continue to pay attention to pt
