evaluating welfare reform in the united states this paper reviews the economic literature on welfare reform over the 1990s a brief summary of the policy changes is followed by a discussion of the methodological techniques that analyze the effects of these changes on outcomes the paper then critically reviews the econometric and experimental literature on caseload changes labor force changes poverty and income changes and family formation changes a growing body of evidence suggests that recent policy changes have influenced economic behavior and well being one particular set of new style welfare programs seems to show especially promising results with significantly increased work and earnings and reduced poverty

new perspectives on capital sticky prices and the taylor principle abstract our main result is that dynamic new keynesian dnk models with firm specific capital feature a substantial amount of endogenous price stickiness we use this insight to assess the desirability of alternative interest rate rules and make the case for combining active monetary policy with interest rate smoothing and or some responsiveness of the nominal interest rate to real economic activity the key mechanism behind our results is also useful from a positive point of view the feature of firm specific capital increases the empirical appealingness of dnk models as documented by a growing body of literature

the out of sample success of term structure models as exchange rate predictors a step beyond abstract a large literature suggests that standard exchange rate models cannot outperform a random walk forecast and that the forward rate is not an optimal predictor of the spot rate however there is evidence that the term structure of forward premia contains valuable information for forecasting future spot exchange rates and that exchange rate dynamics display nonlinearities this paper proposes a term structure forecasting model of exchange rates based on a regime switching vector equilibrium correction model which is novel in this context our model significantly outperforms both a random walk and to a lesser extent a linear term structure vector equilibrium correction model for four major dollar rates across a range of horizons

how should control theory be used to calculate a time consistent government policy we study different solutions to a simple one dimensional linear quadratic game with a large number of private agents and a government a time consistent solution is defined as a solution to the hamilton jacobi bellman equation i e as a policy for which the government has noprecommitment capability this solution is compared to a policy where the government has an instantaneous pre commitment i e an equilibrium in which the government has a period by period leadership in both cases we show how control theory should be applied to calculate the equilibrium and how to relate these equilibria to the differential game literature

long run effects of public sector sponsored training in west germany between 1991 and 1997 west germany spent on average about 3 6 bn euro per year on public sector sponsored training programmes for the unemployed we base our empirical analysis on a new administrative data base that plausibly allows for selectivity correction by microeconometric matching methods we identify the effects of different types of training programmes over a horizon of more than seven years using bias corrected weighted multiple neighbours matching we find that all programmes have negative effects in the short run and positive effects over a horizon of about four years however for substantive training programmes with duration of about two years gains in employment probabilities of more than 10 points appear to be sustainable but come at the price of large negative lock in effects

escaping expectation traps how much commitment is required we study the degree of precommitment that is required to eliminate multiplicity of policy equilibria which arise if the policy maker acts under pure discretion we apply a framework developed by schaumburg and tambalotti 2007 and debertoli and nunes 2010 to a standard new keynesian model with government debt we demonstrate the existence of expectation traps under limited commitment and identify the minimum degree of commitment which is needed to escape from these traps we find that the degree of precommitment which is sufficient to generate uniqueness of the pareto preferred equilibrium requires the policy maker to stay in office for a period of two to five years this is consistent with monetary policy arrangements in many developed countries

when preferences for a stable interest rate become self defeating monetary policymakers often seem to have preferences for a stable interest rate in addition to stable inflation and output in this paper we investigate the implications of having an interest rate level term in the loss function when the policymaker lacks commitment technology we show that such preferences may become self defeating in the sense that they generate a less stable interest rate than in the case without preferences for interest rate stability

discretionary policy and multiple equilibria in lq re models we study discretionary equilibria in dynamic linear quadratic rational expectations models in contrast to the assumptions that pervade this literature we show that these models do have multiple equilibria in some situations we demonstrate the existence of multiple discretionary equilibria by example we investigate general properties of discretionary equilibria and discuss implications for numerical algorithms

expectations and the stability problem for optimal monetary policies eine auf den fundamentaldaten beruhende regelbindung der geldpolitik ohne selbstverpflichtung die bei vollkommen rationalen erwartungen der privaten akteure optimal ware ist instabil wenn diese akteure de facto den ublichen regeln des adaptiven lernens folgen dieses problem lasst sich dadurch beheben dass die erwartungen privater akteure berucksichtigt und in geeigneter weise in die optimale geldpolitik einbezogen werden diese eindeutige schlusfolgerung gilt auch dann wenn sich der geldpolitische entscheidungstrager und die privaten akteure in einem simultanen lernprozess befinden unsere ergebnisse zeigen wie wichtig es ist die geldpolitik angemessen zu gestalten und dabei nicht nur die fundamentaldaten sondern auch direkt die beobachteten erwartungen privater haushalte und unternehmen zu berucksichtigen

survey of western u s electric utility resource plans we review long term electric utility plans representing 90percent of generation within the western united states and canadian provinces we address what utility planners assume about future growth of electricity demand and supply what types of risk they consider in their long term resource planning and the consistency in which they report resource planning related data the region is anticipated to grow by 2percent annually through 2020 before demand side management about two thirds of the utilities that provided an annual energy forecast also reported energy efficiency savings projections in aggregate they anticipate an average 6 4percent reduction in energy and 8 6percent reduction in peak demand by 2020 new natural gas fired and renewable generation will replace retiring coal plants although some utilities anticipate new coal fired plants most are planning for steady growth in renewable generation over the next two decades most planned solar capacity will come online before 2020 with most wind expansion after 2020 fuel mix is expected to remain 55percent of total generation planners consider a wide range of risks but focus on future demand fuel prices and the possibility of ghg regulations data collection and reporting inconsistencies within and across electric utility resource plans lead to recommendations on policies to address this issue

the pre programme earnings dip and the determinants of participation in a social programme implications for simple programme evaluation strategies the key to estimating the impact of a programme is constructing the counterfactual outcome representing what would have happened in its absence this problem becomes more complicated when agents such as individuals firms or local governments self select into the programme rather than being exogenously assigned to it this paper uses data from a major social experiment to identify what would have happened to the earnings of self selected participants in a job training programme had they not participated in it we investigate the implications of these earnings patterns for the validity of widely used before after and difference in differences estimators

solution and estimation of re macromodels with optimal policy macro models of monetary policy typically involve forward looking behavior except in rare circumstances we have to apply some numerical method to find the optimal policy and the rational expectations equilibrium this paper summarizes a few useful methods and shows how they can be combined with a kalman filter to estimate the deep model parameters with maximum likelihood simulations of a macro model with staggered price setting interest rate elastic output and optimal monetary policy illustrate the properties of this estimation approach

evaluation of china s electric energy efficiency under environmental constraints a dea cross efficiency model based on game relationship abstract the traditional data envelopment analysis dea model ignores the cooperation relationship among decision making units dmus so it is difficult to evaluate the dmus efficiency reasonably in this study we use a cross efficiency model considering the game relationship of dmus to evaluate and analyze the provincial electric energy efficiency of china the power industry panel data of china s 30 provinces from 2005 to 2014 are used to evaluate the energy efficiency of china s provincial power industry under environmental constraints in addition based on the obtained values of electric energy efficiency clustering analysis is implemented and the regional similarity in electric energy efficiency is analyzed the results indicate that in the past decade china s provincial electric energy efficiency has not significantly improved and efficiency values have a certain degree of volatility especially in western china in general the electric energy efficiency of eastern china is significantly higher than central and western china the clustering analysis further demonstrates that there is no polarization phenomenon in china s electric energy efficiency in recent years the electric energy efficiency of western china has been greatly improved with significant volatility it reveals that the electric energy efficiency of western china is sensitive to the environment the implementation of energy policies should be adapted to local conditions in the process of formulating policies for improving electric energy efficiency the provincial government should improve the regional opening up layout and establish effective coordination mechanisms among different regions

identification results for duration models with multiple spells the purpose of this paper is to investigate the identifiability of duration models with multiple spells we prove that the results of elbers and ridder 1982 and heckman and singer 1984 can be generalized to multi spell models with lagged duration dependence we also prove that without lagged duration dependence the identification result does not depend on moment conditions or tail conditions on the mixing distribution this result is in contrast to ridder s 1990 result for single spell models

price level versus inflation targeting abstract this paper shows that price level targeting outperforms inflation targeting in the standard new keynesian model under the assumption that the central bank is forced to operate in an environment characterized by discretion in the benchmark case with no persistence in the shocks the commitment solution can be fully replicated intuitively price level targeting introduces history dependence and a stationary level of prices both of which are prominent features of the commitment solution

making the most out of programme evaluations and social experiments accounting for heterogeneity in programme impacts the conventional approach to social programme evaluation focuses on estimating mean impacts of programmes yet many interesting questions regarding the political economy of programmes the distribution of programme benefits and the option values conferred on programme participants require knowledge of the distribution of impacts or features of it this paper presents evidence that heterogeneity in response to programmes is empirically important and that classical probability inequalities are not very informative in producing estimates or bounds on the distribution of programme impacts we explore two methods for supplementing the information in these inequalities based on assumptions about participant decision making processes and about the strength in dependence between outcomes in the participation and non participation states dependence is produced as a consequence of rational choice by participants we test for stochastic rationality among programme participants and present and implement methods for estimating the option values of social programmes

insider power unemployment dynamics and multiple inflation equilibria this paper incorporates employment dynamics due to insider power into the barro gordon theory of inflation unlike in the static barro gordon case and even though our infinitehorizon model is linear quadratic there can be two markov perfect equilibria so that the same unemployment may correspond to either low or high inflation both equilibrium inflation rates measured per unit of the gap between the insiders and government s employment targets are higher than the corresponding rate in the static case the low inflation equilibrium has intuitive comparative statics properties in that inflation is increasing in insider power and the discount factor but the high inflation equilibrium behaves in the opposite way the highinflation equilibrium can be eliminated by a future precommitment to a fixed inflation regime e g erm but only if this precommitment can be made with certainty contrary to the static model inflation may be lower when the union puts a positive weight on a wage target than when it cares only about employment even when this wage target is consistent with a lower employment level than the employment target

speed limit policies the output gap and optimal monetary policy in a standard new keynesian model a myopic central bank concerned with stabilizing inflation and changes in the output gap will implement a policy under discretion that replicates the optimal timeless perspective precommitment policy by stabilizing output gap changes the central bank imparts inertia into output and inflation that is absent under pure discretion even a fully optimizing i e non myopic central bank operating in a discretionary policy environment achieves better social outcomes if it focuses on inflation and changes in the output gap than are achieved under inflation targeting this abstract was borrowed from another version of this item

international business cycles world region and country specific factors the paper investigates the common dynamic properties of business cycle fluctuations across countries regions and the world we employ a bayesian dynamic latent factor model to estimate common components in macroeconomic aggregates output consumption and investment in a 60 country sample covering seven regions of the world the results indicate that a common world factor is an important source of volatility for aggregates in most countries providing evidence for a world business cycle we find that region specific factors play only a minor role in explaining fluctuations in economic activity we also document similarities and differences across regions countries and aggregates jel f41 e32 c11 c32

incorporating energy efficiency into electric power transmission planning a western united states case study abstract driven by system reliability goals and the need to integrate significantly increased renewable power generation long range bulk power transmission planning processes in the united states are undergoing major changes at the same time energy efficiency is an increasing share of the electricity resource mix in many regions and has become a centerpiece of many utility resource plans and state policies as a means of meeting electricity demand complementing supply side sources and reducing carbon dioxide emissions from the electric power system the paper describes an innovative project in the western united states to explicitly incorporate end use efficiency into load forecasts projections of electricity consumption and demand that are a critical input into transmission planning and transmission planning studies institutional and regulatory background and context are reviewed along with a detailed discussion of data sources and analytical procedures used to integrate efficiency into load forecasts the analysis is intended as a practical example to illustrate the kinds of technical and institutional issues that must be addressed in order to incorporate energy efficiency into regional transmission planning activities

an evaluation of the swedish system of active labour market programmes in the 1990s we investigate the presence of short and long term effects from joining a swedish labor market program vis a vis more intense job search in open unemployment overall the impact of the program system is found to have been mixed joining a program has increased employment rates among participants a result robust to a misclassification problem in the data on the other hand it has also allowed participants to remain significantly longer on unemployment benefits and more generally in the unemployment system this being particularly the case for those entitled individuals entering a program around the time of their unemployment benefits exhaustion

optimal simple and implementable monetary and fiscal rules welfare maximizing monetary and fiscal policy rules are studied in a model with sticky prices money and distortionary taxation the ramsey optimal policy is used as a point of comparison the main findings are the size of the inflation coefficient in the interest rate rule plays a minor role for welfare it matters only insofar as it affects the determinacy of equilibrium optimal monetary policy features a muted response to output interest rate rules that feature a positive response to output can lead to significant welfare losses the welfare gains from interest rate smoothing are negligible optimal fiscal policy is passive the optimal monetary and fiscal rule combination attains virtually the same level of welfare as the ramsey optimal policy

space matters understanding the real effects of macroeconomic variations in cross country housing price movements changes in macroeconomic conditions can significantly determine directions and magnitudes of cross country housing price movements we demonstrate that such effects are consistently over estimated when spatial frictions are merely assumed but are not explicitly modeled in the empirical framework the extent of over estimation bias has significant policy implications

the impact of being offered and receiving classroom training on the employment histories of disadvantaged women evidence from experimental data we address two questions using experimental data on disadvantaged women first what is the impact of being offered jtpa classroom training on the duration of unemployment and employment second what is the effect of actually participating in this training on the length of such spells belonging to the treatment group shortens unemployment spells but has no effect on employment spells actually participating in training has a larger positive effect on the exit rate from unemployment than the effect of simply being a member of the treatment group ignoring the endogeneity of actual training in estimation substantially underestimates its effect

monetary and macroprudential policy coordination among multiple equilibria abstract the notion of a tradeoff between output and financial stabilization is based on monetary macroprudential models with unique equilibria using a game theory setup this paper shows that multiple equilibria lead to qualitatively different results monetary and macroprudential authorities have tools that impose externalities on each other s objectives one of the tools macroprudential is coarse while the other monetary policy is unconstrained we find that this asymmetry always leads to multiple equilibria and show that under economically relevant conditions the authorities prefer different equilibria giving the unconstrained authority a weight on helping the constrained authority leaning against the wind now has unexpected effects the relation between this weight and the difficulty of coordinating is hump shaped and therefore a small degree of leaning worsens outcomes on both authorities objectives

evaluating the impact of french employment policies on individual labour market histories this paper deals with the evaluation of some public employment policies set up in france during the 1980 s to improve the labour market prospects of unskilled young workers the evaluation implemented in this paper is restricted to the impact of such public measures on durations and outcomes of subsequent spells of unemployment and employment the econometric study is conducted with non experimental longitudinal microdata recording individual labour nlarket histories a particular attention is paid to the differential effects of various types of measures according to the educational level of recipients programmes involving a higher level of on thejob training such as alternating work training programmes in private firms are principally beneficial to the less educated young workers in contrast for more educated young workers work fare programmes in the public sector decrease the intensity of transition from the subsequent unemployment spell to regular jobs for that subgroup work fare programmes may act as a signal of low employment performance

optimal interest rate smoothing this paper considers the desirability of the observed tendency of central banks to adjust interest rates only gradually in response to changes in economic conditions it shows in the context of a simple model of optimizing private sector behaviour that assignment of an interest rate smoothing objective to the central bank may be desirable even when reduction of the magnitude of interest rate changes is not a social objective in itself this is because a response of policy to irrelevant lagged variables may be desirable owing to the way it steers private sector expectations of future policy

active labor market policy evaluations a meta analysis this article presents a meta analysis of recent microeconometric evaluations of active labour market policies we categorise 199 programme impacts from 97 studies conducted between 1995 and 2007 job search assistance programmes yield relatively favourable programme impacts whereas public sector employment programmes are less effective training programmes are associated with positive medium term impacts although in the short term they often appear ineffective we also find that the outcome variable used to measure programme impact matters but neither the publication status of a study nor the use of a randomised design is related to the sign or significance of the programme estimate

equilibrium coordination with discretionary policy making discretionary policymakers cannot manage private sector expectations and cannot coor dinate the actions of future policymakers as a consequence coordination failures can occur and multiple equilibria can arise in this paper we employ notions of self enforceability and learnability to motivate and identify equilibria of particular interest in discretionary policy problems exhibiting multiple equilibria central among these criteria are whether an equilib rium is robust to the formation of coalitions and whether it is learnable by private agents and jointly learnable by private agents and the policymaker unless the pareto preferred equilibrium is learnable by private agents we find little reason to expect coordination on that equilibrium

managing beliefs about monetary policy under discretion in models of monetary policy discretionary policymaking is typically constrained in its ability to manage public beliefs however when a policymaker possesses private information policy actions serve as signals to the public about unobserved economic conditions and belief management becomes an integral part of optimal discretion policies this article derives the optimal time consistent policy for a general linear quadratic setting the optimal policy is illustrated in a simple new keynesian model where analytical solutions can be derived as well in this model imperfect information about the policymaker s output target leads to lower policy losses

the impact of active labour market programmes on the duration of unemployment in switzerland this article evaluates the effects of swiss active labour market programmes on the job chances of unemployed workers the main innovation is a comparison of two important dynamic evaluation estimators the matching estimator and the timing of events estimator we find that both estimators generate different treatment effects according to the matching estimator temporary subsidised jobs shorten unemployment duration whereas training programmes and employment programmes do not in contrast the timing of events estimator suggests that none of the swiss active labour market programmes shortens unemployment duration the aim of the present article is to study the impact of active labour market policies almps on the duration of unemployment in switzerland the new swiss almps reflect the increasing consensus among policy makers that actively assisting the unemployed in job search is preferable to simply providing them with passive income support the danger is so the argument goes that reliance on passive income support may reduce work incentives and job search activities and therefore increase the risk of long term unemployment almps are seen by many as the key to minimise these risks the question how participation in almp measures affects labour market histories of individuals has been the subject of substantial debate the main problem is that labour market outcomes for participants may be systematically different from non participants

inflation forecast contracts we introduce a new type of incentive contract for central bankers inflation forecast contracts which make central bankers remunerations contingent on the precision of their inflation forecasts we show that such contracts enable central bankers to influence inflation expectations more eectively thus facilitating more successful stabilization of current inflation inflation forecast contracts improve the accuracy of inflation forecasts but have adverse consequences for output on balance paying central bankers according to their forecasting performance improves welfare

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

active labor market policy effects in a dynamic setting this paper develops and implements a method to identify and estimate treatment effects in a dynamic setting where treatments may occur at any point in time by combining the standard matching approach to the timing of events approach it demonstrates that the effect of the treatment on the treated at a given date can be identified although non treated may be treated later in time the approach builds on a no anticipation assumption and the assumption of conditional independence between the duration before treatment and the duration before exit to illustrate the approach the paper studies the effect of training for unemployed workers in france using a rich register data set training has little impact on unemployment duration the contamination of the standard matching estimator due to later entries into treatment is large if the treatment probability is high

housing is local applying a dynamic unobserved factor model for the dutch housing market abstract we employ the multi factor extension of the otrok and whiteman 1998 single dynamic unobserved factor model in order to investigate regional dutch house price fluctuations for the years 1995 2012 this paper is mainly concerned with two questions first is the dutch housing market localized second to which factors can we trace back this localization we find that the dutch housing market is highly localized although there is an important common housing cycle explaining house price comovement across all regions idiosyncratic factors play the most important role although notably group specific factors separating randstad of non randstad regions are only of minor importance nevertheless they can explain region specific housing supply shocks this latter finding can be partly traced back towards an agglomeration effect for randstad regions

differences in wage distributions between canada and the united states an application of a flexible estimator of distribution functions in the presence of covariates we construct a tractable flexible functional form estimator of cumulative distribution functions for non negative random variables which admits large numbers of covariates the estimator adopts and extends techniques from the spell duration literature for estimating hazard functions to distribution functions for wages earnings and income we apply these methods to investigate sources of wage inequality for full time male workers between canada and the united states finding that the canadian wage density has a thinner left tail because low educated workers have higher pay and a thinner right tail because of a lower proportion of highly educated workers unions appear to play a large role in these outcomes

the effects of welfare to work program activities on labor market outcomes studies examining welfare to work program effectiveness present mixed and sometimes discrepant findings partly due to research design data and methodological limitations using administrative data on missouri and north carolina welfare recipients we substantially improve on past estimation approaches to identify the distinct effects of each state s welfare to work subprograms assessment job search assistance and job readiness training and more intensive programs designed to augment human capital more intensive training is associated with greater initial earnings losses but also greater long run earnings gains the negative program impacts we observe in quarters immediately following participation turn positive by the second year after participation
