a political economy model of congressional careers our main goal is to quantify the returns to a career in the united states congress we specify a dynamic model of career decisions of a member of congress and estimate this model using a newly collected dataset given estimates of the structural model we assess reelection probabilities estimate the effect of congressional experience on private and public sector wages and quantify the value of congressional seat moreover we assess how an increase in the congressional wage or the imposition of term limits would affect the career decisions of politicians and the returns from a career in congress

winding number criterion for existence and uniqueness of equilibrium in linear rational expectations models abstract this paper develops a simple geometric criterion for the existence and uniqueness of equilibrium in linear rational expectations lre models the class of models considered is very general and includes models with infinitely many lags and or leads of endogenous variables i show that the criterion is tightly related to the familiar blanchard and kahn econometrica 48 5 1980 1305 hansen and sargent rational expectations and econometric practice 1981 and whiteman linear rational expectations models a user s guide 1983 conditions for the existence and uniqueness of equilibrium in lre models the new criterion can be used to extend the policy rule robustness analysis of onatski and stock macroeconomic dynamics 6 1 2002 85 from purely backward looking models to forward looking models

term limits and pork barrel politics abstract we develop a dynamic model of democratic politics in which both potential office holders and the electorate have heterogeneous ideologies voters have incomplete information about candidate ideologies so they must use information from previous positions taken in office to make informed re election decisions we characterize the effects of term limits on the evolution over time of the ideological positions taken by office holders and derive the implications for voter choice and welfare contributions of our paper include we detail how pork provision by more senior incumbents interacts with term limits to affect electoral outcomes pork provision transfers of resources from districts with junior legislators to districts with more senior legislators induces voters to be more forgiving of extreme location by incumbents especially incumbents in small or poor districts pork provision can explain why re election probabilities in congress exceed those for governors term limits reduce voter welfare when all that matters are the ideological positions taken by the office holder term limits may be advantageous when senior incumbents can extract benefits for their constituencies at the expense of districts with more junior representatives large or rich districts especially value term limits when there is substantial pork provision we characterize the welfare of all voters not just the median voter

output dynamics in real business cycles models the time series literature reports two stylized facts about output dynamics in the united states gnp growth is positively autocorrelated and gnp appears to have an important trend reverting component this paper investigates whether current real business cycle rbc models are consistent with these stylized facts many rbc models have weak internal propagation mechanisms and must rely on external sources of dynamics to replicate both facts models that incorporate labor adjustment costs are partially successful they endogenously generate positive autocorrelation in output growth but they need implausibly large transitory shocks to match the trend reverting component in output

control functions and simultaneous equations methods economic models of agent s optimization problems or of interactions among agents often exhibit simultaneity it is well known that any function in which an explanatory variable is partly determined by the dependent variable of the function cannot be identified without additional information typically this additional information is provided by observable exogenous variables or functional structures here we focus on nonlinear simultaneous equations models with nonadditive disturbances nonlinear nonadditive specifications are a fundamental feature of economic models with unobserved heterogeneity including multidimensional models of consumer and producer choice models of nash equilibrium in industrial organization and many models of labor market behavior in linear models with additive disturbances there are many alternative approaches to addressing endogeneity in estimation twostage least squares instrumental variable and control function approaches are three such commonly adopted approaches in simple specifications of the linear simultaneous model all three approaches generate consistent often analytically identical estimators hausman 1987 for example however linear models with additive

term limits and electoral accountability abstract periodic elections are the main instrument through which voters can hold politicians accountable from this perspective term limits which restrict voters ability to reward politicians with re election appear counterproductive we show that despite the disciplining effect of elections term limits can be ex ante welfare improving from the perspective of voters by reducing the value of holding office term limits can induce politicians to implement policies that are closer to their private preferences such truthful behavior by incumbents in turn results in better screening of incumbents we characterize under which circumstances two term or even longer term limits are the optimal institution for voters

an equilibrium model of the business cycle with household production and fiscal policy the authors estimate a dynamic general equilibrium model of the u s economy that includes an explicit household production sector and stochastic fiscal variables they use their estimates to investigate two issues first the authors analyze how well the model accounts for aggregate fluctuations they find that household production has a significant impact and reject a nested specification in which changes in the home production technology do not matter for market variables second the authors study the effects of some simple fiscal policy experiments and show that the model generates different predictions for the effects of tax changes than similar models without home production copyright 1997 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

time to build and aggregate fluctuations some new evidence this paper presents maximum likelihood estimates and tests of a model similar to one kydland and prescott 1982 suggested for this purpose it derives equilibrium laws of motion for a set of aggregate variables as functions of the model s parameters and the innovation to the technology shock the paper shows that a single unobservable index can explain the variability in the observed series but identifying the single index with the innovation to the technology shock implies that per capita hours is not well explained it also shows that time separable preferences with respect to leisure are consistent with the data copyright 1989 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

aggregate fluctuations as an information transmission mechanism a model is presented in which individuals attempt to track shocks with a capital like quantity that is costly to produce and to adjust the shocks have separate individual specific and economy wide components individuals do not have direct access to desired information about economy wide shocks the information is potentially available from the observation of endogenous aggregates but because the aggregates are endogenous there is an informational externality associated with them two polar cases are considered when the desired information is about economy wide real shocks as in townsend 1983 the externality is potentially completely internalized when the desired information is about purely nominal aggregates as in lucas 1973 1975 aggregate fluctuations are a necessary condition of equilibrium

a method for taking models to the data abstract this paper develops a method for combining the power of a dynamic stochastic general equilibrium model with the flexibility of a vector autoregressive time series model to obtain a hybrid that can be taken directly to the data it estimates this hybrid model via maximum likelihood and uses the results to address a number of issues concerning the ability of a prototypical real business cycle model to explain movements in aggregate output and employment in the postwar us economy the stability of the real business cycle model s structural parameters and the performance of the hybrid model s out of sample forecasts

the conventional treatment of seasonality in business cycle analysis does it create distortions abstract no so says one model that is broadly consistent with postwar u s seasonal and business cycle data

current real business cycle theories and aggregate labor market fluctuations hours worked and the return to working are weakly correlated traditionally the ability to account for this fact has been a litmus test for macroeconomic models existing real business cycle models fail this test dramatically we modify prototypical real business cycle models by allowing government consumption shocks to influence labor market dynamics this modification can in principle bring the models into closer conformity with the data our empirical results indicate that it does

bridging dsge models and the raw data abstract a method to estimate dsge models using the raw data is proposed the approach links the observables to the model counterparts via a flexible specification which does not require the model based component to be located solely at business cycle frequencies allows the non model based component to take various time series patterns and permits certain types of model misspecification applying standard data transformations induces biases in structural estimates and distortions in the policy conclusions the proposed approach recovers important model based features in selected experimental designs two widely discussed issues are used to illustrate its practical use

imperfect information and the house price in a general equilibrium model abstract house prices have inertia which may be because housing market participants need time to recognize long booms and recessions within a dynamic stochastic general equilibrium model with an endogenous market for housing i consider the case of rational expectations subject to imperfect information about the persistence of exogenous shocks i evaluate the performance of the model against the last 40 years of key u s macroeconomic data bayesian comparison strongly favors the model over the baseline case with perfect information under imperfect information agents rely on learning to form expectations which improves the ability of the model to generate realistic low frequency house price dynamics however as long as the agents form expectations rationally the improvement is limited furthermore to confine price inertia within the housing market is a challenge for the general equilibrium approach

does electoral accountability affect economic policy choices evidence from gubernatorial term limits this paper analyzes the behavior of u s governors from 1950 to 1986 to investigate a reputation building model of political behavior we argue that differences in the behavior of governors who face a binding term limit and those who are able to run again provides a source of variation in discount rates that can be used to test a political agency model we find evidence that taxes spending and other policy instruments respond to a binding term limit if a democrat is in office the result is a fiscal cycle in term limit states which lowers state income when the term limit binds

cross asset speculation in stock markets in practice heterogeneously informed speculators combine private information about multiple stocks with information in prices taking into account how their trades influence the inferences of other speculators via prices we show how this speculation causes prices to be more correlated than asset fundamentals raising price volatility the covariance structure of asset fundamentals drives that of prices while the covariance structure of liquidity trade drives that of order flows we characterize how speculator profits vary with the distributions of information and liquidity trade across assets and speculators and relate the cross asset factor structure of order flows to that of returns

a method for estimating the timing interval in a linear econometric model with an application to taylor s model of staggered contracts abstract this paper describes and implements a procedure for estimating the timing interval in any linear econometric model the procedure is applied to taylor s model of staggered contracts using annual averaged price and output data the fit of the version of taylor s model with serially uncorrelated disturbances improves as the timing interval of the model is reduced

clearing up the fiscal multiplier morass bayesian prior predictive analysis of five nested dsge models suggests that model specifications and prior distributions tightly circumscribe the range of possible government spending multipliers multipliers are decomposed into wealth and substitution effects yielding uniform comparisons across models by constraining the multiplier to tight ranges model and prior selections bias results revealing less about fiscal effects in data than about the lenses through which researchers choose to interpret data when monetary policy actively targets inflation output multipliers can exceed one but investment multipliers are likely to be negative passive monetary policy produces consistently strong multipliers for output consumption and investment

time to build and aggregate fluctuations abstract this paper studies the contribution of time to build to the explanation of business cycle phenomena using a simple version of the neoclassical model the analysis shows that it is not evident that multiperiod construction is crucial to the theory of fluctuations

processed food exports from developing countries patterns and determinants abstract a noteworthy recent development in world trade is the rapid expansion of processed food exports this development and its policy implications have received little attention in the literature on export led industrialisation in developing countries dcs the purpose of this paper is to redress this oversight firstly by providing an overview of the growth patterns of processed food exports and then examining the determinants of inter country differences in growth performance the results point to the growing importance of food manufacturing as a dynamic export line for many dcs there is also evidence that the policy regime is far more important than resource endowments and other country specific factors in explaining inter country differences in export success in this product area as in the case of conventional manufactured exports

on the theory of piecemeal tariff reform the case of pure imported intermediate inputs what is the effect of a tariff reduction that applies only to a subset of commodities subject to tariffs this important question was addressed systematically for the first time by james meade 1955 ch 13 in his classic work trade and welfare after a careful analysis meade concluded t here is more likely to be a gain in economic welfare if the rate of duty is high on the primary imports which will come in in increased volume and is low on the secondary imports which will come in in reduced volume p 208 this result was proved formally by trent j bertrand and jaroslav vanek 1971 who demonstrated that in a small open economy if the highest tariff rate is reduced to the next highest one welfare will rise provided the import demand for the good with the highest tariff exhibits gross substitutability with respect to all other goods 2 subsequently following a different strand of the literature as exemplified in john green 1961 tatsuo hatta 1973 1977 and peter lloyd 1974 independently proved similar results in terms of hicksian substitutability 3 in deriving their results bertrand and vanek allowed for the use of final goods as intermediate inputs i e interindustry flows 4 however neither they nor the subsequent writers including hatta and lloyd allowed for the existence of pure imported intermediate inputs that are not produced domestically therefore a natural question is whether the piecemeal policy prescription derived by them remains valid in the presence of pure imported intermediates this question is particularly important for developing countries for two reasons first by far the bulk of the imports of developing countries are intermediate and capital goods according to the world bank during the period 1975 1985 50 percent of developing countries imports were accounted for by intermediate inputs and an additional 30 percent were capital goods a sizable proportion of both capital and intermediate goods are neither produced nor directly consumed in these countries second the meade bertrand vanekhatta lloyd result has been the cornerstone of trade policy reform in many developing countries especially during the last decade in most countries trade reform has been based on the so called concertina approach under which the highest tariffs are reduced to the next highest ones and then to the next highest ones and so on thus lopez professor department of agricultural and resource economics university of maryland college park md 20742 and consultant trade policy division world bank 1818 h street n w washington dc 20433 panagariya senior economist trade policy division world bank 1818 h street n w washington dc 20433 and professor department of economics university of maryland college park md 20742 the findings interpretations and conclusions in this paper are entirely those of the authors they do not necessarily represent the views of the world bank its executive directors or the countries they represent the authors are indebted to two referees and tatsuo hatta for valuable comments on an earlier draft iin this quotation primary imports refers to the goods on which tariffs are reduced while secondary imports refers to other importables subject to tariffs 2robert lipsey and kelvin lancaster 1956 had proved the basic result of bertrand and vanek in a one factor three good model with a cobb douglas utility function 3more recently takashi fukushima 1979 has proved the validity of the hatta lloyd result when the highest tariff is shared by several commodities while rodney falvey 1988 has done the same in the presence of quantitative restrictions on imports 4although hatta 1973 1977 did not allow explicitly for interindustry flows his results can also be shown to be valid in the presence of such flows

an analytical approach to new keynesian models under the fiscal theory abstract this article illustrates a widely applicable frequency domain methodology to solving multivariate linear rational expectations models as an example we solve a prototypical new keynesian model under the assumption that primary surpluses evolve independently of government liabilities a regime in which the fiscal theory of the price level is valid the resulting analytical solution is useful in characterizing the cross equation restrictions and illustrating the complex interaction between the fiscal theory and price rigidity we also highlight some useful by products of such method which are not easily obtainable for more sophisticated models using time domain methods

rational expectations in stationary linear models linear time series models have come to dominate the macroeconomic literature on rational expectations and equilibrium business cycle theory but the explicit solution of such models has generally required strong restrictions upon the exogenous process of stochastic shocks e g temporal independence as well as upon the values of various demand and supply elasticities this paper exhibits a solution technique the method of z transforms which does not require one to impose such restrictions the value of this method is illustrated by applying it to completely characterize the symmetric stationary rational expectations equilibria of a naive linear model of land speculation this approach also permits systematic study of the informationally asymmetric equilibria of the model this paper develops a method for analyzing rational expectations re equilibria in linear economic models the methods i shall discuss usually enable one to determine whether or not a given model has a re equilibrium and if one exists to exhibit an explicit expression for the stochastic process of equilibrium prices the techniques apply to linear models driven by stationary processes of exogenous random shocks

constructing and estimating a realistic optimizing model of monetary policy abstract a dynamic stochastic general equilibrium dsge model with real and nominal both price and wage rigidities succeeds in capturing some key nominal features of u s business cycles additive technology shocks as well as multiplicative shocks are introduced and shown to be crucial monetary policy is specified as an interest rate targeting rule following developments in the structural vector autoregression var literature the interaction between real and nominal rigidities is essential to reproduce the liquidity effect of monetary policy the model is estimated by maximum likelihood on u s data and its fit is comparable to that of an unrestricted first order var besides producing reasonable impulse responses and second moments this model replicates a feature of u s business cycles never captured by previous research with dsge models that an increase in interest rates predicts a decrease in output two to six quarters in the future

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

the macroeconomic effects of distortionary taxation abstract prescott 1986 estimates that technology shocks account for 75 of the fluctuations in the postwar u s economy this paper reestimates the contribution of technological change for a standard business cycle model that includes a public sector and fiscal disturbances i find that a significant fraction of the variance of aggregate consumption investment output capital stock and hours of work can be explained by disturbances in labor and capital tax rates and government consumption i also use the model to quantify the welfare costs of capital and labor taxation for both the time series and welfare calculations maximum likelihood estimates of taste technology and policy parameters are used

reconciling voters behavior with legislative term limits a puzzle exists over why voters continually re elect their congressional and state representatives although these same voters often support initiatives to limit the number of terms that their legislators may serve residents of california colorado and oklahoma voted in 1990 to limit the terms of their state legislators to tenures ranging from six to twelve years 1 in california these same voters however re elected 87 of 91 or 96 percent of all incumbent state representatives and senators whose terms they sought to limit 2 among re elected incumbents 67 or 77 percent had served as long as or longer than the maximum term prescribed under their state s term limit initiative voters defeated only two incumbents who would have been removed under the terms of california s tenure restrictions had they been in effect similar voter behavior characterized recent state elections in colorado and oklahoma 3 more generally these seemingly contradictory voter preferences also are apparent in public opinion polls at the federal level while 62 percent of voters immediately prior to the 1990 general elections indicated their intentions to reelect their congressman that same poll showed that only 24 percent said they approve of the way congress is handling its job gallup and newport 1990 pp 36 37 support for term limit initiatives and the low public esteem of legislators as a group both appear to be inconsistent with voters strong preferences for their own representative and the regular reelection of incumbents

why did the incumbency advantage in u s house elections grow theory a simple rational entry argument suggests that the value of incumbency consists not just of a direct effect reflecting the value of resources such as staff attached to legislative office but also of an indirect effect reflecting the fact that stronger challengers are less likely to contest incumbent held seats the indirect effect is the product of a scare off effect the ability of incumbents to scare off high quality challengers and a quality effect reflecting how much electoral advantage a party accrues when it has an experienced rather than an inexperienced candidate hypothesis the growth of the overall incumbency advantage was driven principally by increases in the quality effect methods we use a simple two equation model estimated by ordinary least squares regression to analyze u s house election data from 1948 to 1990 results most of the increase in the incumbency advantage at least down to 1980 came through increases in the quality effect i e the advantage to the incumbent party of having a low quality challenger this suggests that the task for those wishing to explain the growth in the vote denominated incumbency advantage is to explain why the quality effect grew it also suggests that resource based explanations of the growth in the incumbency advantage cannot provide a full explanation

implementation cycles investment and growth we develop a model of intrinsic cycles driven by the decentralized behavior of entrepreneurs and firms making continuous divisible improvements in their productivity we show that when the introduction of productivity improvements is endogenous implementation cycles arise even in the presence of reversible investment and consumption smoothing the implied cyclical equilibrium is unique within its class and shares several features in common with actual business cycles in particular its predictions are qualitatively consistent with the joint behavior of the investment rate and tobin s q during u s recessions

overtime effort and the propagation of business cycle shocks abstract this paper presents and estimates a variant of hansen and sargent s 1988 real business cycle model with straight time and overtime the model presented has only one latent variable the state of technology yet it does a better job propagating and magnifying shocks than the labor hoarding models which incorporate unobserved effort this model as well as a version of burnside eichenbaum and rebelo s 1993 labor hoarding model is estimated using maximum likelihood the maximum likelihood parameter estimates are compared to those using gmm

the effects of trade liberalization on imports in selected developing countries abstract this paper analyses the impact of the reduction of tariff and nontariff barriers on the imports of 22 selected developing countries utilizing dynamic panel data techniques domestic income and relative prices are found to be significant determinants of import growth in addition the results indicate that import duties reduce import growth but the effect varies according to the region and the type of trade policy regime existing in the country the results also show that the elimination of trade policy distortions has a strong positive impact on import growth finally it is found that income and price elasticities are higher as a result of trade policy reform

forecasting the forecasts of others implications for asset pricing we develop a dynamic asset pricing model with heterogeneously informed agents unlike previous research we focus on the general case where differential information leads to the problem of forecasting the forecasts of others and to non trivial dynamics of higher order expectations in particular we prove that the model does not admit a finite number of state variables using numerical analysis we compare equilibria characterized by identical fundamentals but different information structure we demonstrate that the distribution of information has substantial impact on equilibrium prices and returns in particular we show that asymmetric information can generate momentum in returns and high trading volume

real exchange rate dynamics revisited a case with financial market imperfections abstract in this paper we investigate the relationship between real exchange rate dynamics and financial market imperfections for this purpose we first construct a new open economy macroeconomics noem model that incorporates staggered loan contracts as a simple form of the financial market imperfections our model with such a financial market friction replicates persistent volatile and realistic hump shaped responses of real exchange rates which have been thought very difficult to materialize in standard noem models remarkably these realistic responses can materialize even with both supply and demand shocks such as cost push loan rate and monetary policy shocks this implies that the financial market development is a key element for understanding real exchange rate dynamics

flip flopping ideological adjustment costs in the united states senate models of electoral competition in which candidates can change position at no cost predict the convergence of platforms in a two candidate election such convergence is at odds with empirical observation in this paper i undertake a study of candidate positioning in the united states senate and determine the extent to which electoral costs associated with changing position explain the ideological positions taken by senators using over 50 years of roll call voting data i use a simulated method of moments approach to estimate a dynamic model of candidate positioning for u s senators the ndings support a model in which senators face convex costs to changing position with the best tting model being one with linear costs of adjustment the model thus predicts severe punishments for ip opping senators those who make large changes in position as a result of the signi cant costs associated with adjusting position the empirical validity of the median voter theorem which depends upon candidates being able to change position at no cost is called into question

using repeat challengers to estimate the effect of campaign spending on election outcomes in the u s house previous studies of congressional spending have typically found a large positive effect of challenger spending but little evidence for effects of incumbent spending those studies however do not adequately control for inherent differences in vote getting ability across candidates high quality challengers are likely to receive a high fraction of the vote and have high campaign expenditures even if campaign spending has no impact on election outcomes to avoid that bias this paper examines elections in which the same two candidates face one another on more than one occasion differencing eliminates the influence of any fixed candidate or district attributes estimates of the effects of challenger spending are an order of magnitude below those of previous studies campaign spending has an extremely small impact on election outcomes regardless of who does the spending campaign spending limits appear socially desirable but public financing of campaigns does not

a structural model of electoral accountability this paper proposes a structural approach to measuring the eects of electoral ac countability we estimate a political agency model with imperfect information in order to identify and quantify discipline and selection eects using data on u s governors for 1982 2012 we nd that the possibility of reelection provides a signi cant incentive for incumbents to exert eort we also nd a selection eect although it is weaker in terms of its eect on average governor performance according to our model the widely used two term regime improves voter welfare by 4 2 compared to a one term regime and nd that a three term regime may improve voter welfare even further

estimating and testing rational expectations models when the trend specification is uncertain abstract this paper explores various strategies for estimating and testing rational expectations models when the trend specification is uncertain one approach seeks to make estimators and tests robust to trend misspecification by reducing the influence of low frequency dynamics however contrary to intuition the effects of trend specification errors are not confined to low frequencies but are spread across the entire frequency domain thus operations that damp low frequency components do not remove trend specification errors and are not sufficient for constructing robust estimators and tests another approach seeks representations of approximating models that do not condition on a specification of the trend and it uses gmm to estimate parameters and test over identifying restrictions because these methods do not condition on assumptions about trends they are robust to errors in that part of the approximating model

the case for trade liberalization in developing countries in a broad swing of the pendulum developing countries have been shifting from severe and destructive protection to free trade fever many of the notable examples are in latin america mexico after a major unilateral trade liberalization is now negotiating a free trade agreement with canada and the united states chile traditionally a highly protected country is a leading example of reducing trade barriers argentina and brazil have entered free trade agreements a free trade area for the americas is becoming a serious possibility the enthusiasm for more openness of the economy is not limited to latin america for example korea and turkey are cases of highly successful liberalization there are also cases in africa for example ghana and botswana to demonstrate the possibility and the benefits of opening up this new enthusiasm for freer trade stems from four overlapping sources anti statism the world has seen a broad intellectual swing away from emphasizing the beneficial role of the state in the 1980s and protection is seen as one of the manifestations of an overly intrusive state of course a shift to a liberal trade regime has not always been the by product of a more democratic society chile under pinochet or korea in its liberalizing phase were under authoritarian rule two cheers for the market but not three the saying goes today the market gets at least three cheers which may be at least one too many poor economic performance many developing countries have suffered dismal economic performance and declining productive potential much of the reason can be traced to populist macroeconomic policies that engendered debt crises and hyperinflation of course part of the reason was also a very adverse external environment but since the days of plentiful external credit are gone

solving generalized multivariate linear rational expectations models abstract we generalize the linear rational expectations solution method of whiteman 1983 to the multivariate case this facilitates the use of a generic exogenous driving process that must only satisfy covariance stationarity multivariate cross equation restrictions linking the wold representation of the exogenous process to the endogenous variables of the rational expectations model are obtained we argue that this approach offers important insights into rational expectations models we give two examples in the paper an asset pricing model with incomplete information and a monetary model with observationally equivalent monetary fiscal policy interactions we relate our solution methodology to other popular approaches to solving multivariate linear rational expectations models and provide user friendly code that executes our approach

congressional committees and the political economy of federal outlays the literature on the organization of the united states congress has been dominated by distributive and informational theory one important source of disagreement between these two theories is their characterization of whether individual legislators can engage in pork barrel activities here we provide evidence which indicates that the pork barrel is alive and well in the contemporary united states congress we focus on whether members of power and constituency committees can direct disproportionate federal expenditures to their districts finding strong and systematic evidence of pork barrel activities by committee members provides empirical support for distributive theories of legislative organization

technology shocks and the business cycle on empirical investigation abstract this paper uses maximum likelihood to estimate a prototypical real business cycle model under several different assumptions regarding the stochastic process governing technological change the estimation approach permits the use of formal statistical hypothesis tests to help discriminate between competing specifications the approach also allows each specification to be evaluated based on its ability to generate accurate out of sample forecasts overall the results indicate that the data prefer a version of the model in which technology shocks are extremely persistent but still trend stationary

term limits and electoral competitiveness evidence from california s state legislative races california s legislative term limits have dramatically reduced campaign expenditures real expenditures during the three general elections after the term limits initiative passed in 1990 were lower than in even 1976 this drop has occurred at the same time that races have become closer contests and more candidates are running for office by any measure term limits have coincided with large changes in the level of political competition even before term limits have forcibly removed a single politician from office the changes are so large that more incumbents are being defeated races are closer more candidates are running and fewer single candidate races than occur at any other time during our sample period from 1976 to 1994

posterior predictive evidence on us inflation using extended new keynesian phillips curve models with non filtered data changing time series properties of us inflation and economic activity measured as marginal costs are modeled within a set of extended new keynesian phillips curve nkpc models it is shown that mechanical removal or modeling of simple low frequency movements in the data may yield poor predictive results which depend on the model specification used basic nkpc models are extended to include structural time series models that describe typical time varying patterns in levels and volatilities forward and backward looking expectation components for inflation are incorporated and their relative importance is evaluated survey data on expected inflation are introduced to strengthen the information in the likelihood use is made of simulation based bayesian techniques for the empirical analysis no credible evidence is found on endogeneity and long run stability between inflation and marginal costs backward looking inflation appears stronger than forward looking inflation levels and volatilities of inflation are estimated more precisely using rich nkpc models the extended nkpc structures compare favorably with existing basic bayesian vector autoregressive and stochastic volatility models in terms of fit and prediction tails of the complete predictive distributions indicate an increase in the probability of deflation in recent years

how equilibrium prices reveal information in a time series model with disparately informed competitive traders abstract accommodating asymmetric information in a dynamic asset pricing model is technically challenging due to the problems associated with higher order expectations that is rational investors are forced into a situation where they must forecast the forecasts of other agents in a dynamic setting this problem telescopes into the infinite future and the dimension of the relevant state space approaches infinity by using the frequency domain approach of whiteman linear rational expectations models a user s guide university of minnesota press minneapolis 1983 and kasa forecasting the forecasts of others in the frequency domain rev econ dynam 3 2000 726 756 this paper demonstrates how information structures previously believed to preserve asymmetric information in equilibrium converge to a symmetric information rational expectations equilibrium the revealing aspect of the price process lies in the invertibility of the observed state space which makes it possible for agents to infer the economically fundamental shocks and thus eliminating the need to forecast the forecasts of others

maximum likelihood in the frequency domain the importance of time to plan abstract we illustrate the use of various frequency domain tools for estimating and testing dynamic stochastic general equilibrium models we show how to exploit the well known fact that the log gaussian density function has a linear decomposition in the frequency domain we also propose a new resolution to the problem that the phase angle between two variables is not uniquely determined these methods are applied to the analysis of business cycles our substantive findings confirm existing results in the literature which suggest that time to plan in the investment technology has a potentially useful role to play in business cycle analysis

the price of pork the seniority trap in the u s house abstract using data on federal outlays and u s house elections i estimate the effect of the pork barrel on the quality of officeholders taking into account the fact that seniority creates a dynamic linkage across periods after estimating the parameters governing the influence of seniority on federal outlays and the parameters governing the distributions of candidate quality i conduct several policy experiments to uncover the size of the welfare loss created by the seniority system i find that the seniority system negatively impacts the quality of representatives but has little effect on the outcomes of elections furthermore the most commonly proposed solution to the distortion term limits may have a significant negative effect on the quality of sitting representatives instead of a quantity constraint term limits i propose a change in the relative price of seniority by way of a pigouvian tax on seniority such a policy achieves the first best outcome

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

real business cycles in this paper we demonstrate how certain very ordinary economic principles lead maximizing individuals to choose consumption production plans that display many of the characteristics commonly associated with business cycles our explanation is entirely consistent with i rational expectations ii complete current information iii stable preferences iv no technological change v no long lived commodities vi no frictions or adjustment costs vii no government viii no money and ix no serial dependence in the stochastic elements of the environment we also provide a completely worked out example of the type of artificial economy we have in mind the time series properties of the example exhibit some major features of observed business cycles although this type of model may not be capable of explaining all of the regularities in actual business cycles we believe that it provides a useful well defined benchmark for assessing the relative importance of factors e g monetary disturbances

pork barrel politics and electoral returns at the local level does the targeted spending of public resources provide electoral benefits for incumbents despite the attention of scholars to that question the empirical results are mixed thus far the present paper supplies insights into the electoral benefits of discretionary funding on local elections i study the consequences of pork barrel politics in 7355 competitive mayoral elections in slovakia between 2006 and 2018 finding that more grants from the central government enhance the likelihood of mayors winning reelection the same advantage applies to mayors whose municipalities receive grants in local election years the effects of the number of grants obtained as well as the timing of their distribution are however moderated by municipal population more specifically a larger number of grants and resources obtained near the end of the mayoral term provides electoral benefits only to small town mayors but give no advantage to the mayors of larger urban areas

the impact of federal spending on house election outcomes while it is widely believed by academics politicians and the popular press that incumbent members of congress are rewarded by the electorate for bringing federal dollars to their district the empirical evidence supporting that claim is extremely weak one explanation for the failure to uncover the expected relationship between federal spending and election outcomes is that incumbents who expect to have difficulty being reelected are likely to exert greater effort in obtaining federal outlays since it is generally impossible to adequately measure this effort the estimated impact of spending is biased downward because of an omitted variable bias we address this estimation problem using instrumental variables for each house district we use spending outside the district but inside the state containing the district as an instrument for spending in the district federal spending is affected by a large number of actors e g governors senators mayors and other house members in the state delegation

seniority in legislatures we construct a stochastic game model of a legislature with an endogenously determined seniority system we model the behavior of the legislators as well as their constituents in an infinitely repeated divide the dollar game each legislative session must make a decision on redistributional issues modeled as a divide the dollar game however each session begins with a vote in which the legislators decide by majority rule whether or not to impose on themselves a seniority system legislative decisions on the redistributional issues are made by the baron ferejohn rule an agenda setter is selected by a random recognition rule which in our model is a function of the seniority system selected the agenda setter makes a proposal on redistributional issues and the legislature then votes whether to accept or reject the agenda setters proposal if the legislature rejects the proposal another agenda setter is randomly selected and the process is repeated if the legislature accepts the proposal the legislative session ends and the voters in each legislative district vote whether to retain their legislator or throw it out of office the voters verdict determines the seniority structure of the next period legislature we find a stationary equilibrium to the game having the property that the legislature imposes on itself a non trivial seniority system and that legislators are always reelected
