unemployment risk and precautionary wealth evidence from households balance sheets this paper examines precautionary behavior by relating job loss risk to household net worth we use existing best practice and some new strategies to deal with some problematic issues inherent in this literature regarding proxying uncertainty instrumentation and incorporating theoretical restrictions we do not find precautionary variation in the wealth holdings of households with low permanent income but do find precautionary effects for moderate and higher income households when the dependent variable is total net worth these findings are robust to several alternative specifications but we do not find precautionary responses in subaggregates of wealth that exclude home equity

an equilibrium model of wealth distribution i present an explicitly solved equilibrium model for the distribution of wealth and income in an incomplete markets economy i flrst propose a self insurance model with an inter temporally dependent preference uzawa 1968 lucas and stokey 1984 and obstfeld 1990 i then derive an analytical consumption rule which captures stochastic precautionary saving motive and generates stationary wealth accumulation finally i provide a complete characterization for the equilibrium cross sectional distribution of wealth and income in closed form by developing a recursive formulation for the moments of the distribution of wealth and income using this recursive formulation i show that income persistence and the degree of wealth mean reversion are the main determinants of wealth income correlation and relative dispersions of wealth to income such as skewness and kurtosis ratios between wealth and income

consumption and saving with habit formation and durability abstract this paper develops a model of precautionary saving with habit formation and durability durability offsets the effects of habit formation on both consumption growth and the precautionary premium empirical tests of habit formation and durability on consumption growth might exploit their parallel effects on the precautionary premium

behavioral responses to risk in rural china does risk perpetuate poverty in a credit constrained economy jalan and ravallion study portfolio and other behavioral responses to measured risk using household panel data for rural china one quarter of wealth is held in unproductive liquid forms but only a small share of this appears to be a precaution against income risk the authors estimate that eliminating income risk would reduce the share of wealth held in liquid form by less than 1 percentage point moreover that effect is confined largely to middle income groups high income households do not it seems need to hold unproductive cautionary wealth and the poor probably cannot afford to do so the authors find no evidence that income risk discourages schooling but risk does inhibit the out migration of labor generally the results provide only limited support for the idea that uninsured risks promote unproductive portfolio behavior in this setting there is such an effect but it is small in magnitude and cannot be deemed an important cause of poverty

an analytical approximate solution to the problem of precautionary savings abstract this paper considers the problem of precautionary savings for an expected utility specification with finite horizon the exact solution is known for only a few cases numerical methods have limited applications because of bellman s curse of dimensionality this paper derives a simple analytical approximate solution for a general specification of the felicity function which is linear in the variance of the innovations on human wealth numerically the approximation is very accurate for realistic values of the parameters of the problem

permanent and transitory movements in labor income an explanation for excess smoothness in consumption many have argued that if labor income is difference stationary the permanent income hypothesis predicts that consumption should be relatively volatile in u s aggregate data labor income is well characterized as having a unit root however consumption turns out to be relatively smooth this anomaly is known as deaton s paradox i resolve deaton s paradox by providing decompositions of labor income into permanent and transitory components these preserve the univariate dynamic properties of labor income however when agents distinguish permanent and transitory movements in their labor income as the rational expectations hypothesis asserts they should the permanent income hypothesis correctly predicts the observed smoothness in consumption

precautionary savings a panel study theoretical literature shows that income uncertainty boosts saving yet empirical work is incomplete i test for the precautionary motive for saving using panel data knowing this motive s size is important for gauging the responsiveness of saving to government programs that reduce uncertainty and for comparison to other motives such as bequests most empirical studies of precautionary saving use either aggregate time series or cross sectional data which cannot capture the effects of individual income uncertainty i derive measures of total permanent and transitory income uncertainty from panel data the national longitudinal survey and find a strong precautionary motive a doubling of uncertainty increases the ratio of wealth to permanent income by 29

precautionary behavior migrant networks and household consumption decisions an empirical analysis using household panel data from rural china abstract we develop a test of precautionary behavior in the consumption decisions of rural agricultural households among surveyed households facing a median level of consumption risk 10 of savings can be attributed to a precautionary motive and this increases to 15 for households with consumption per capita below the poverty line we next use distant lags of local rainfall shocks uncorrelated with current consumption growth to identify the size of migrant networks outside the village and then present evidence that both poor and nonpoor households engage in less precautionary saving as the size of the village migrant network increases

slow information diffusion and the inertial behavior of durable consumption this paper studies the aggregate dynamics of durable and nondurable consumption under slow information diffusion sid due to noisy observations and learning within the permanent income framework we show that sid can significantly improve the model s predictions on the joint behavior of income durable consumption and nondurable consumption at the aggregate level specifically we find that sid can significantly improve the model s predictions for i smoothness in durable and nondurable consumption ii autocorrelation of durable consumption and iii contemporaneous correlation between durable and nondurable consumption furthermore we discuss that incorporating a fixed cost into our sid model does a better job of reproducing the infrequent adjustments of durable consumption at the individual level and the slow adjustments at the aggregate level

household production and the excess sensitivity of consumption to current income empirical research on the permanent income hypothesis pih has found that consumption growth is excessively sensitive to predictable changes in income this finding is interpreted as strong evidence against the pih we propose an explanation for apparent excess sensitivity that is based on a quantitative equilibrium model of household production in which permanent income consumers respond to shifts in sectoral wages and prices by substituting work effort and consumption across home and market sectors although the pih is true this mechanism generates apparent excess sensitivity because market consumption responds to predictable income growth

the family as an incomplete annuities market families can self insure against uncertain dates of death through implicit or explicit agreements with respect to consumption and interfamily transfers interfamily transfers need have nothing to do with altruistic feelings they may simply reflect risk sharing behavior of completely selfish family members although family annuity markets are incomplete even small families can substitute by more than 70 percent for perfect market annuities given adverse selection and transaction costs family risk pooling may be preferred to public market annuities in the absence of public annuities these risk sharing arrangements provide powerful incentives for marriage and family formation

to vote or not to vote the paradox of nonvoting one paradox of voting states that in a general election in which many citizens vote the probability that a single voter can affect the outcome is so small that in general citizens have no rational reason for voting however if all citizens accept this reasoning then none will vote and so each vote has a large probability of affecting the outcome hence all should vote after all the adoption of mixed strategies resolves this paradox if each citizen adopts a certain small probability of voting then the actual number of citizens voting will be just enough to make it worth those citizens while to vote a nash equilibrium point thus occurs here we compute nash equilibria for the simple case of majority voting for the more complicated case of composite voting for example as in a presidential election we draw certain qualitative inferences

learning ricardian equivalence abstract this paper tests whether subjects learn to comply with the ricardian equivalence proposition in a life cycle consumption laboratory experiment our results suggest that ricardian equivalence does not hold on average tax changes have a significant and strong impact on consumption choice using individual consumption time series the behaviour of 56 of our subjects can be classified as inconsistent with the ricardian equivalence proposition classifying subjects according to rules of thumb that best describe their behaviour we find that subjects switch less to rules that theoretically violate ricardian equivalence in later rounds compared to earlier rounds this implies that some subjects learn to comply with ricardian equivalence by changing their consumption strategy however the aggregate effect of taxation on consumption persists even after eight rounds of repetition

aggregate stochastic implications of the life cycle hypothesis this paper sets forth some key aggregate stochastic implications of the modigliani brumberg 1980 life cycle hypothesis and explores the extent to which a properly aggregated life cycle model can help to explain the first and second moment properties of changes in per capita consumption the principal finding of the paper which to my knowledge is new is that smooth per capita consumption in the presence of permanent shocks to per capital labor income is exactly the outcome one should expect from a properly aggregated life cycle model in which saving for retirement as well as for consumption smoothing is a motive for asset accumulation

precaution and liquidity in the demand for housing we exploit cross sectional mortgage data to investigate the importance of liquidity constraints and a precautionary motive in the demand for housing households that are not liquidity constrained consume housing services essentially as the life cycle hypothesis suggests but with a significant precautionary component households that are liquidity constrained in terms of not meeting standard loan to value or payments to income constraints are similar to unconstrained households in most respects including the precautionary motive but they respond somewhat less to fluctuations in their lifetime income suggesting some influence of bank induced liquidity constraints we additionally find however that banks enforce liquidity constraints only weakly jel d91 d12 r21 i introduction the benchmark theory in the economics of consumption is the life cycle or permanent income hypothesis lcpi based on the work of modigliani and brumberg 1954 and friedman 1957 its empirical validity is sometimes questionable especially when compared against alternatives that incorporate liquidity constraints or the precautionary motive for saving see for instance deaton 1992 for a survey rejection of the lcpi may however be just a manifestation of the poor quality of consumption data at the micro level these data are typically subject to the reporting biases and omissions inherent in consumer surveys there are further difficulties in measuring a desired stream of consumption services nondurable consumption goods are a small fraction of total consumption and in the case of food essentials hardly a consumer choice variable durable consumption goods have the feature that they are lumpy and that the consumption services at any point in time are hard to measure we propose to test the lcpi at the micro level with a quite different type of data the data are obtained from the residential mortgage finance database collected by the national association of realtors they are based on actual home purchases and the associated mortgage transactions reported by realtors and thus avoid some of the reporting biases of the consumer surveys more important they allow us to accurately identify households that in principle have instantaneous access to additional liquidity by lowering the down payment for the house purchase or increasing the size of the loan further the purchase of a house provides an accurate measure of a relatively large fraction of consumption services obtained for a medium to long horizon and measured at the time of the consumption decision although our data also have some serious shortcomings they allow a look at the lcpi from an unconventional vantage point perhaps the most influential study employing the standard consumer survey in testing the lcpi at the micro level is that of hall and mishkin 1982 it examines food expenditure from the panel study of income dynamics one of their key results is that consumption tracks income more closely than would be expected under the lcpi they demonstrate that this result could be explained by assuming a group of liquidity constrained consumers consuming their income at each point in time of 20 of the total sample some of the drawbacks of this study are the use of food expenditures to represent consumption the underreporting of income and absence of proper wealth data inherent in the consumer survey and the associated inability to individually separate liquidity constrained consumers from the rest of the sample several previous studies have attempted to improve on this way of testing the lcpi by examining other data sets bernanke 1984 used data on durable consumption goods automobiles to overcome the drawbacks of using food consumption in the hall and mishkin study his results support the lcpi but are still suspect because of possible reporting biases and the lack of good wealth and savings observations

life cycle consumption under social interactions abstract in this paper we examine how social interactions affect consumption decisions at various levels of aggregation in a life cycle economy made up of peer groups for this purpose we consider two analytically solvable life cycle models one under certainty equivalent behavior and one under prudence and explicitly allow for three different forms of social interactions in peer groups namely conformism altruism and jealousy we show that whether social interactions have any effects on individuals optimal consumption decisions critically depends on intertemporal rather than static considerations this is true regardless of whether individuals preferences are time separable or exhibit habit formation and whether information within peer groups is homogeneous or disparate it implies that analyzing the effects of social interactions in static rather than intertemporal settings is likely to be misleading we also show that social interactions when coupled with either habit formation or prudence can significantly strengthen the effects of habit formation or prudence in the direction of resolving two well known puzzles in the literature on the permanent income hypothesis namely excess smoothness and excess sensitivity

the permanent income hypothesis estimation and testing by instrumental variables the permanent income hypothesis with rational expectation is restated estimated and tested by an instrumental variables technique on the postwar u s aggregate time series data the hypothesis is accepted on a consumption series which includes service flows from consumer durables if the consumption series is the one in the national income and product accounts the hypothesis is decisively rejected an explanation is suggested to reconcile the conflicting test results

family labor supply and asset returns abstract we study how shocks to wages and asset prices affect consumption and labor supply decisions of two earner households in a life cycle framework with housing and flexible preferences we provide a micro foundation of the wealth effects on consumption and labor supply we find evidence for non separability between non durable consumption housing services and hours of work the results also highlight the importance of family labor supply in understanding how households respond to shocks to financial and housing markets

equilibrium consumption and precautionary savings in a stochastically growing economy abstract the derivation of a closed form solution for consumption based on the constant elasticity utility function in the presence of stochastic labor income has proved to be intractable this paper derives a closed form equilibrium relationship between consumption and wealth one that holds along a balanced growth path in a stochastic romer endogenous growth model by employing more general recursive preferences we can disentangle the coefficient of relative risk aversion from the intertemporal elasticity of substitution the effects of key structural parameters on equilibrium consumption and its tradeoff with leisure are analyzed a significant aspect of our analysis concerns the extent to which current risk in the economy is shared between labor and capital this plays an important role in determining the impact of risk on the economy in general and on consumption in particular formal analysis is supplemented with extensive numerical simulations

macroeconomic uncertainty precautionary saving and the current account abstract the relationship between current account developments and changes in the macroeconomic environment is a key issue in open economy macroeconomics this paper extends the standard intertemporal model of the current account to incorporate the effects of macroeconomic uncertainty on external saving behavior it is shown that the greater the uncertainty in national cash flow defined as output less investment less government consumption the greater will be the incentive for precautionary saving and ceteris paribus the larger the current account surplus empirical support for the model is found using post war quarterly data for the united states japan and the united kingdom as well as a long time series 1919 1990 for the united states

imperfect insurance and differing propensities to consume across households abstract this paper extends previous tests of consumption insurance by splitting the sample to examine whether the marginal propensity to consume mpc out of idiosyncratic income shocks is larger for low wealth households than it is for high wealth households using data from the psid i find 1 the mpc of low wealth households is higher than that of high wealth households there are indications that both precautionary savings behavior and liquidity constraints contribute to this difference 2 splitting the data using two different measures of wealth indicates that households perceive housing equity as illiquid 3 when low wealth households are split into two subgroups the mpc of the very low wealth group is smaller reflecting the insurance aspects of means tested safety net programs

optimal saving rules for loss averse agents under uncertainty abstract most empirical studies assume only monotonic preferences for households behavioral research however provides substantial evidence that preferences for wealth are measured relative to a reference point in this paper we introduce and solve a two period consumption and savings model for a loss averse agent who measures utility from consumption relative to a benchmark level the solution is given as a parametric decision rule with one unknown parameter that depends on the distribution of the return on saving we find non linearity in the fraction of wealth saved where the specific saving pattern depends on the sign of the real return on savings the amount of saving is nondecreasing in initial wealth and the riskiness of the return distribution

risk pooling precautionary saving and consumption growth in this paper we model the evolution of income risk and consumption growth we decompose the time series innovation of the income process into its common and cohort specific components from these we compute conditional variances which are used as separate risk terms in a consumption growth equation using a long series of british household data we exploit the time series variation to identify precautionary saving effects and find strong evidence of their importance specifically after allowing for demographic and labour market status there is an independent role for income risk in explaining consumption growth rather than the component that is common across cohorts however it is the cohort specific element that is important in determining changes in consumption growth this result points to a failure of between cohort insurance mechanisms

husband s unemployment and wife s labor supply the added worker effect across europe this article investigates the responsiveness of women s labor supply to their husband s job loss the so called added worker effect the authors contribute to the literature by taking an explicit internationally comparative perspective in analyzing the variation of the added worker effect across welfare regimes using longitudinal data from the european union statistics on income and living conditions eu silc survey covering 28 european countries from 2004 to 2013 they find evidence of an added worker effect which however varies over both the business cycle and the different welfare regimes in europe the latter result might be explained in part by differences in the design of the unemployment benefit system across countries which create different incentives for the labor supply of wives of unemployed men

why is consumption so smooth for thirty years it has been accepted that consumption is smooth because permanent income is smoother than measured income this paper considers the evidence for the contrary position that permanent income is in fact less smooth than measured income so that the smoothness of consumption cannot be straightforwardly explained by permanent income theory the paper argues that in postwar u s quarterly data consumption is smooth because it responds with a lag to changes in income

optimal consumption and portfolio policies when asset prices follow a diffusion process abstract we consider a consumption portfolio problem in continuous time under uncertainty a martingale technique is employed to characterize optimal consumption portfolio policies when there exist nonnegativity constraints on consumption and on final wealth we also provide a way to compute and verify optimal policies our verification theorem for optimal policies involves a linear partial differential equation unlike the nonlinear partial differential equation of dynamic programming the relationship between our approach and dynamic programming is discussed we demonstrate our technique by explicitly computing optimal policies in a series of examples in particular we solve the optimal consumption portfolio problem for hyperbolic absolute risk aversion utility functions when the asset prices follow a geometric brownian motion the optimal policies in this case are no longer linear when nonnegativity constraints on consumption and on final wealth are included by these examples one can see that our approach is much easier than the dynamic programming approach

huggett economies with multiple stationary equilibria abstract i obtain a closed form solution to a huggett economy with constant absolute risk aversion cara utility when the vector of individual state variables follows a var 1 process with an arbitrary shock distribution the stationary equilibrium is unique if the income process is ar 1 but not necessarily so otherwise with gaussian shocks i provide general sufficient conditions for the existence of at least three equilibria when the income process is either arma 1 1 ar 2 or has a persistent transitory pt representation with negatively correlated shocks the possibility of multiple equilibria calls for caution in comparative statics exercises and policy analyses using heterogeneous agent models as an illustration i provide an example in which the welfare implication of changing the income risk goes in opposite directions depending on the choice of equilibrium

expressive voting and government redistribution testing tullock s charity of the uncharitable models of expressive voting postulate that voters will consume ideological stances on issues by voting for them even when they are against the voter s own narrow selfinterest if the probability of being a decisive voter is low when a voter is unlikely to sway the outcome the odds that avoter will incur any real personal cost a higher tax burden for example from her own expressive vote is small we testand find support for tullock s straightforward empiricalimplication of this model that government welfare transfer payments are inversely related to the probability of being thedecisive voter

precautionary savings and the permanent income hypothesis this paper derives the explicit solution of a dynamic stochastic optimal consumption problem for infinitely lived agents whose preferences exhibit in the presence of non diversifiable labour income uncertainty a constant elasticity of intertemporal substitution and constant absolute risk aversion the constancy of the elasticity of intertemporal substitution which implies that marginal utility at zero consumption is infinite guarantees that the non negativity constraint on consumption is never binding along the optimal path the assumption of constant absolute risk aversion allows an explicit computation of human wealth and provides a simple representation of the precautionary savings motive

robustly strategic consumption portfolio rules with informational frictions this paper provides a tractable continuous time constant absolute risk aversion gaussian framework to explore how the interactions of fundamental uncertainty model uncertainty due to a preference for robustness and state uncertainty due to information processing constraints rational inattention affect strategic consumption portfolio rules and precautionary savings in the presence of uninsurable labor income specifically after solving the model explicitly i compute and compare the elasticities of strategic asset allocation and precautionary savings to risk aversion robustness and inattention furthermore for plausibly estimated and calibrated model parameters i quantitatively analyze how the interactions of model uncertainty and state uncertainty affect the optimal share invested in the risky asset and show that they can provide a potential explanation for the observed stockholding behavior of households with different education and income levels this paper was accepted by neng wang finance

microfoundations and the demand for money the reader should note that i write this piece in a style that aims to be accessible to that much neglected representative agent the woman on the eurostar train hence unlike the man on the clapham omnibus i assume my intrepid traveller has reasonable knowledge of monetary economics and econometrics but not of the details of the demand for money space constraints force me to indulge in a certain amount of poetic licence but i hope this results in poetic justice there have been many wars fought on this particular battlefield some with almost religious zeal on the theoretical side of the debate we sometimes have the equivalent of religious fundamentalists be they muslims jews christians etc who would dismiss almost any evidence unless it were associated with a strong microtheoretic basis as laid down in the koran talmud or bible the empirical side encompasses agnostics atheists as well as born again econometricians pure theorists inhabit the sunlit uplands while applied economists and policymakers flounder in the muddy plain below occasionally gaining solace from their copy of zen and the art of motorcycle maintenance in general in economics we do not have the luxury of controlled experiments as is the case in the natural sciences what distinguishes good microfoundations from bad and how to weight priors and statistical evidence is subject to much dispute leamer i983 hendry et al i990 as in religion sometimes there is the occasional miracle proclaimed after a suitable interval a new saint may be declared and disciples flock to the new shrine later doubts may arise as to whether a miracle really did occur human behaviour is difficult to explain let alone predict so the search for the equivalent of the holy grail ark of the covenant etc is bound to be arduous in scholarly journals we generally read of the success of the demand for money like diplomats who are sent abroad to lie for the good of their country publication may require applied economists to be somewhat economical with the actualite lovell i983 leamer i983 in this article i want to be as honest as possible about our success and failures in this area the prior information an armchair economist would consider when thinking about the demand for money over the past 40 years in western industrialised countries which have experienced moderate inflation might

the sensitivity of consumption to transitory income estimates from panel data on households we investigate the stochastic relation between income and consumption specifically consumption of food within a panel of about 2 000 households our major findings are 1 consumption responds much more strongly to permanent than to transitory movements of income 2 the response to transitory income is nonetheless clearly positive 3 a simple test independent of our model of consumption rejects a central implication of the pure life cycle permanent income hypothesis the observed covariation of income and consumption is compatible with pure life cycle permanent income behavior on the part of80 percent of families and simple proportionality of consumption and income among the remaining 20 percent as a general matter our findings support the view that families respond differently to different sources of income variations in particular temporary income tax policies have smaller effects on consumption than do other more permanent changes in income of the same magnitude this abstract was borrowed from another version of this item

a comment on durable goods consumption abstract this paper examines the time series behavior of durables nondurables and services consumption expenditure of six oecd countries following caballero s approach in each country durables expenditure exhibits greater reversion than nondurables and services when lower frequencies of the series are examined the results reject the frictionless pih as a model for durable goods consumption however they strongly support mankiw s hypothesis on the nature of durable goods consumption

consumption puzzles and precautionary savings abstract when marginal utility is convex agents accumulate savings as a precautionary measure against labor income eventualities this paper shows that precautionary savings can go a long way in making the excess growth excess smoothness and excess sensitivity features of consumption consistent with the stochastic processes of labor income observed in the u s at the microeconomic level

equity return predictability time varying volatility and learning about the permanence of shocks abstract i consider a consumption based asset pricing model where the consumer does not know if shocks to dividends are stationary temporary or non stationary permanent the agent uses a bayesian learning algorithm with a bias towards recent observations to assign probability to each process while the true process is stationary the consumer s beliefs change as he misinterprets a drift in dividends from their steady state value as an increased likelihood that the dividend process is non stationary belief changes result in large swings in asset prices which are subsequently reversed the model then is consistent with a broad array of asset pricing puzzles it predicts the negative correlation between current returns and future returns and the pe ratio and future returns consistent with the data i also find that consumption growth negatively correlates with future returns and the pe ratio and consumption growth forecast future consumption growth the model amplifies return volatility over the benchmark rational expectations case and exactly matches the standard deviation of consumption finally the model generates time varying volatility consistent with the data on quarterly equity returns

an investigation of ricardian equivalence in a common trends model abstract to empirically discriminate between ricardian and non ricardian behaviour we have to use a method that distinguishes between expected and unexpected as well as permanent and transitory changes in taxes and government consumption one method that provides these distinctions between different types of changes is the common trends framework used in this paper which is a var model with cointegrating constraints in the empirical study of us data there is some support for the ricardian hypothesis but there are also some deviations from its predictions however the differences do not lend support to a keynesian view of budget deficits but rather to the view of expansionary fiscal contractions this can be motivated theoretically by uncertainty about future taxes in combination with prudent households

precautionary saving an explanation for excess sensitivity of consumption the permanent income hypothesis under certainty equivalence yields a martingale consumption process empirically this hypothesis is rejected because consumption is excessively sensitive to anticipated income one approach to account for excess sensitivity is to relax certainty equivalence by using utility functions that induce precautionary saving this article analyzes a hyperbolic absolute risk aversion utility function empirically some reasonable parameterizations of this specification allow one to match the excess sensitivity associated with the data these parameterizations also permit one to account for the excess smoothness problem excess sensitivity and excess smoothness however do not reflect the same phenomenon

groups in rational turnout models a model of the strategic calculus of voting that incorporates the behavior of groups is presented if candidates choose different positions positive turnout is possible in partial equilibrium and is generally larger than that without group rationality nevertheless if candidates are probability maximizers and a unique general equilibrium exists the candidates will choose equivalent positions and turnout will be zero even with group rationality but if candidates care about both policy and winning they will choose different positions and cause positive turnout this turnout will be larger than that that would occur without group rationality group rationality alone cannot explain positive turnout in a general equilibrium theory of elections it does imply larger turnout in conjunction with policy oriented candidates than would be predicted solely by individualistic rational behavior

cyclical uncertainty precautionary saving and economic growth this paper studies the interaction between cyclical uncertainty precautionary saving and economic growth in a stochastic endogenous growth model the analysis provides insight into the potential connection between technological uncertainty of the sort popularized in real business cycle models and the determinants of economic growth in a stochastic version of a popular model of endogenously determined economic growth the magnitude of the link between cyclical uncertainty and growth is quantified and found to be small in terms of its effect on the growth rate but possibly large in terms of its effect on levels of macroeconomic variables moreover the welfare costs of reduced cyclical uncertainty can be substantial owing to the lower historical rate of capital accumulation induced by a decrease in precautionary saving the chief implications of the model are found to be roughly consistent with the postwar experience of several countries although the predictions of the model with regard to growth rates are too small to explain much of the variation in growth rates across time or across countries

idiosyncratic production risk growth and the business cycle we introduce a neoclassical growth economy with idiosyncratic production risk and incomplete markets each agent is an entrepreneur operating her own technology with her own capital stock the general equilibrium is characterized by a closed form recursion in the cara normal case incomplete markets introduce a risk premium on private equity which reduces the demand for investment as compared to complete markets the steady state can thus have both a lower capital stock due to investment risk and a lower interest rate due to precautionary savings furthermore the anticipation of high real interest rates in the future feeds back into high risk premia and low investment in the present thus slowing down convergence to the steady state our results highlight the importance of private risk premia for capital accumulation and business cycles

de centralization and voter turnout theory and evidence from german municipalities a vast academic literature illustrates that voter turnout is affected by the institutional design of elections e g compulsory voting electoral system postal or sunday voting in this article we exploit a simple downsian theoretical framework to argue that the institutional framework of public good provision and in particular the distribution of political and administrative competences across government levels likewise affects voters turnout decisions by influencing the expected net benefit of voting empirically we exploit the institutional variation across german municipalities to test this proposition and find supportive evidence

precautionary saving and fuzzy information abstract we consider a two period life cycle model where uncertainty about future labour income is modelled by a fuzzy set applying a defuzzification strategy that explicitly takes the individual s behaviour towards risk into account we show that pessimistic individuals engage in precautionary savings even if marginal utility is not convex e g in case of a quadratic utility function

the deaton paradox in a long memory context with structural breaks this article contributes to the permanent income hypothesis pih and excess consumption smoothness debate in the context of fractional integration we show that the excess consumption smoothness result is a consequence of the quarterly data frequency commonly employed in the empirical work in fact the i 1 hypothesis is rejected for the income process with monthly data in favour of a fractional integration order lower than 1 moreover if a structural break is taken into account we observe a substantial reduction in the degree of consumption smoothness especially after the break found in 1975

the rational voter paradox revisited the rational voter paradox rests on two fundamental assumptions first that voters are risk neutral second that voters make decisive vote computations the implications of maximizing the expected utility of wealth rather than the utility of expected wealth are explored the validity of decisive vote computations are examined through concepts of weak and strict in the limit free rider assumptions the paper proposes a margin of victory model of voting behavior based on information levels and the political division of labor

precautionary saving in the small and in the large the theory of precautionary saving is shown to be isomorphic to the arrow pratt theory of risk aversion making possible the application of a large body of knowledge about risk aversion to precautionary saving and more generally to the theory of optimal choice under risk in particular a measure of the strength of the precautionary saving motive analogous to the arrow pratt measure of risk aversion is used to establish a number of new propositions about precautionary saving and to give a new interpretation of the dreze modigliani substitution effect copyright 1990 by the econometric society

induced uncertainty market price of risk and the dynamics of consumption and wealth abstract in this paper we examine the implications of model uncertainty or robustness rb for consumption and saving and the market price of uncertainty under limited information processing capacity rational inattention or ri first we show that ri by itself creates an additional demand for robustness that leads to higher induced uncertainty facing consumers second if we allow capacity to be elastic rb increases the optimal level of attention third we explore how the induced uncertainty composed of i model uncertainty due to rb and ii state uncertainty due to ri affects consumption and wealth dynamics the market price of uncertainty and the welfare losses due to incomplete information we find that induced uncertainty can better explain the observed consumption income volatility and market price of uncertainty low attention increases the effect of model misspecification
