animal spirits and credit cycles in this paper we extend the behavioral macroeconomic model as proposed by de grauwe 2012 to include a banking sector the behavioral model takes the view that agents have limited cognitive abilities as a result it is rational to use simple forecasting rules and to subject the use of these rules to a fitness test agents are then driven to select the rule that performs best the behavioral model produces endogenous and self fulfilling movements of optimism and pessimism animal spirits our main result is that the existence of banks intensifies these movements creating a greater scope for booms and busts thus banks do not create but amplify animal spirits we find that increases in the equity ratios of banks tend to reduce the importance of animal spirits over the business cycle the other policy conclusion we derive from our results is that the central bank has an important responsibility for stabilising output output stabilization is an instrument to tame the animal spirits this has the effect of improving the trade off between inflation and output volatility

the role of cognitive limitations and heterogeneous expectations for aggregate production and credit cycle abstract the behavioural model of de grauwe and macchiarelli 2015 is extended to include financial frictions on the aggregate supply side the result is a tight and sustained feedback loop between animal spirits on one hand and supply of credit capital purchase and production on the other during phases of optimism credit is abundant access to production capital is easy the cash in advance constraint is lax risks are undervalued and production is booming upon reversal in market sentiment the contraction is quick and deep moreover the model is capable of replicating the stylized fact of a long and sustained simultaneous growth in credit production and asset prices observed in the us since mid1990 s lastly the behavioural model does a decent job in matching us data including multiple supply side relations including capital firm credit and inflation interest rate

a behavioral model of the credit cycle abstract in a behavioral variant of a new keynesian model in which individuals use simple heuristic rules to forecast future inflation and output if there are limits on the amount of debt that economic agents are allowed to bear we observe occasionally severe downturns differences in beliefs combined with borrowing constraints tend to dampen expansions but give rise to a chain reaction that exacerbates the recessions the model is an example of endogenous credit cycles with expansions severe recessions and persistent inequality in the distribution of wealth monetary policy can both stabilize the economy and cause increased average output

poverty and public policy the problem of poverty is particularly acute in india with 14 of the world s population we have the misfortune of having almost twice as large a share of the world s poor indeed as i shall presently underline the question of poverty and its amelioration has been at the center of our concerns from the beginning of our planning efforts almost four decades ago little therefore can be said on it that some distinguished indian economist has not already said in some ways therefore to talk on the design of public policy for poverty to an indian audience is to carry coal to newcastle or as the old saying goes to teach your grandmother how to suck eggs nonetheless i hope to provide a fresh perspective by putting the problem into an explicit analytical framework that permits alternative policy designs to be sharply defined and contrasted i also intend to draw on international experience to put our efforts and problems into both historical and comparative perspectives

taking stock a rigorous modelling of animal spirits in macroeconomics modelling animal spirits this paper is a survey of the burgeoning literature that seeks to take the enigmatic concept of the animal spirits more seriously by building heterodox macro dynamic models that can capture some of its crucial aspects in a rigorous way two approaches are considered the discrete choice and the transition probability approach where individual agents face a binary decision and choose one of them with a certain probability these assessments are adjusted upward or downward in response to what the agents observe which leads to changes in the aggregate sentiment and the macroeconomic variables resulting from the corresponding decisions typical applications of the two approaches alternatively give rise to what will be called a weak and a strong form of animal spirits on the whole the literature included in this survey provides examples of applications of a modelling tool that demonstrates a considerable flexibility within a canonical framework

performance of monetary policy with internal central bank forecasting abstract recent models of monetary policy have analyzed the desirability of different optimal and ad hoc interest rules under the restrictive assumption that forecasts of the private sector and the central bank are homogeneous this paper studies the implications of heterogeneity in forecasting by the central bank and private agents for the performance of interest rules in a framework of econometric learning

nutrition and labor producvivity in agriculture estimates for rural south india using panel data for rural south india a fixed effects individual wage equation and farm production function are estimated that have calorie intake and nutritional status weight for height of workers as their arguments neither market wages nor farm output are observed to be responsive to changes in the daily energy intake of workers however both are highly elastic with respect to weight for height these results suggest that while the human body can adapt to inadequate nutrition in the short run it cannot adapt as readily to chronic malnutrition that eventually results in loss of weight for height copyright 1988 by mit press

poverty and the forward falling labor supply function a microeconomic analysis abstract existing subsistence efficiency target income and limited aspiration theories impose a backward bending labor supply behavior on poor workers in less developed countries recent empirical studies of worker behavior in the unorganized sectors of ldcs contradict this view and report evidence of both a forward falling and an upward rising labor supply this study formulates an increasing elasticity of substitution utility function model to analyze the observed behaviors the function displays both nonhomotheticity and variable elasticity properties and is capable of generating labor supply curves with forward falling and upward rising segments while the upward rising supply is considered to be usual worker behavior the forward falling segment represents a below subsistence distress sale phenomenon and the subsistence income of the worker is implied to occur at the turning point joining the two segments of the supply curve econometric estimates of the utility and the labor supply functions provide support to the theoretical results

health shocks and natural resource management evidence from western kenya poverty and altered planning horizons brought on by the hiv aids epidemic can change individual discount rates altering incentives to conserve natural resources using longitudinal household survey data from western kenya we estimate the effects of health status on investments in soil quality as indicated by households agricultural land fallowing decisions we first show that this effect is theoretically ambiguous while health improvements lower discount rates and thus increase incentives to conserve natural resources they also increase labor productivity and make it more likely that households can engage in labor intensive resource extraction activities we find that household size and composition are predictors of whether the effect of health improvements on discount rates dominates the productivity effect or vice versa since households with more and younger members are better able to reallocate labor to cope with productivity shocks the discount rate effect dominates for these households and health improvements lead to greater levels of conservation in smaller families with less substitutable labor the productivity effect dominates and health improvements lead to greater environmental degradation

the labour market impact of body weight in china a semiparametric analysis while a positive wage effect of body mass index bmi is widely observed in low income developing countries a negative wage effect of bmi is often observed in high income developed countries to fill the gap between these previous findings we investigate the relationship between body weight and wages in transition economies we focus on china whose rapid economic growth of the 1990s was followed by a rapid increase in overweight and obesity while still experiencing significant food insecurity and underweight we first use several parametric regression strategies to obtain a consistent estimate of the wage effects of weight second we adopt a semiparametric partially linear model that allows for endogeneity of weight parametric regressions provide mixed results and the sign and magnitude of their estimates are sensitive to the choice of samples and regression strategies semiparametric estimates provide evidence of a wage penalty for very heavy and thin persons among both men and women the wage pena

sticky information in general equilibrium this paper develops and analyzes a general equilibrium model with sticky information the only rigidity in goods labor and financial markets is that agents are inattentive sporadically updating their information sets when setting prices wages and consumption after presenting the ingredients of such a model the paper develops an algorithm to solve this class of models and uses it to study the model s dynamic properties it then estimates the parameters of the model using u s data on five key macroeconomic time series it finds that information stickiness is present in all markets and is especially pronounced for consumers and workers variance decompositions show that monetary policy and aggregate demand shocks account for most of the variance of inflation output and hours jel e30 e10

predicting the next step of a random walk experimental evidence of regime shifting beliefs barberis et al j financial econ 49 1998 307 construct a model in which investors use the prevalence of past trend reversals as an indicator of the likelihood of future reversals while such regime shifting beliefs are consistent with a variety of psychological theories other contrary predictions are consistent with the same theories we report two experiments with mba student participants that strongly support the existence of regime shifting beliefs we conclude that regime shifting models can provide a useful framework for understanding market anomalies including underreactions to earnings changes and overreactions to longterm earnings trends r 2002 published by elsevier science b v

using survey data to test standard propositions regarding exchange rate expectations survey data provide a measure of exchange rate expectations superior to the forward rate in that no risk premium interferes we estimate extrapolative adaptive and regressive models of expectations static or random walk expectations and bandwagon expectations are rejected current appreciation generates the expectation of future depreciation because variables other than the contemporaneous spot rate receive weight in comparing expectations to the process governing the spot rate we find statistically significant bias no variable is as ubiquitous in international financial theory and yet as elusive empirically as investors expectations regarding exchange rates in the past expectations have been modeled in an ad hoc way often by using the forward exchange rate there is however a serious problem with using the forward discount as the measure of the expected change in the exchange rate in that the two may not be equal the gap that may separate the forward discount and expected depreciation is generally interpreted as a risk premium most of the large empirical literature testing the unbiasedness of the forward exchange rate for example has found it necessary either arbitrarily to assume away the existence of the risk premium if the aim

monetary policy for inattentive economies we offer a contribution to the analysis of optimal monetary policy we begin with a critical assessment of the existing literature arguing that most work is based on implausible models of inflation output dynamics we then suggest that this problem may be solved with some recent behavioral models which assume that price setters are slow to incorporate macroeconomic information into the prices they set a specific such model is developed and used to derive optimal policy in response to shocks to productivity and aggregate demand optimal policy is price level targeting base drift in the price level which is implicit in the inflation targeting regimes currently used in many central banks is not desirable in this model when shocks to desired markups are added optimal policy is flexible targeting of the price level that is the central bank should allow the price level to deviate from its target for a while in response to these supply shocks but it should eventually return the price level to its target path optimal policy can also be described as an elastic price standard the central bank allows the price level to deviate from its target when output is expected to deviate from its natural rate

wage and labor supply effects of illness in cote d ivoire and ghana instrumental variable estimates for days disabled abstract sickness should make individuals less productive but there are problems in measuring this effect first how is adult morbidity measured in a household survey second how is the impact or morbidity on productivity inferred if earning is partly used to improve health self reported functional activity limitation due to illness is considered an indicator of morbidity for wage earners and self employed people to deal with both the measurement and joint determination problems an instrumental variable estimation approach is used where local food prices and health services instrument for disability days that reduce wages by at least 10 and hours by 3 or more

health and productivity in a heterogeneous urban labour market the effects of changes in various health indicators on hourly earnings in different sectors of the labour market are examined using survey data from conakry guinea greater height which is associated with greater strength raises earnings of men both in self employment and the private wage sector where work is likely to involve physical labour height does not matter for women s earnings which likely reflects the less physically strenuous nature of most women s activities body mass index treated as an endogenous variable appears to raise earnings of men in self and private wage employment and of women in self employment no impacts are found for household per capita calorie and protein availability also treated as endogenous overall the results suggest that health matters for productivity in poor urban environments with these effects depending on gender and the sector of employment or type of work

business fluctuations in a behavioral switching model gridlock effects and credit crunch phenomena in financial networks abstract in this paper we characterize the evolution over time of a credit network in the most general terms as a system of interacting banks and firms operating in a three sector economy with goods credit and interbank market credit connections change over time via an evolving fitness measure depending from lenders supply of liquidity and borrowers demand of credit moreover an endogenous learning mechanism allows agents to switch between a loyal or a shopping around strategy according to their degree of satisfaction the crucial question we investigate is how financial bubbles and credit crunch phenomena emerge from the implemented mechanism

a simple adaptive measure of core inflation this paper proposes a new measure of core inflation and compares it with several existing measures the new measure is adaptive and is designed to track sudden and persistent movements in inflation such as those arising from changes in monetary policy regimes the adaptive measure filters out transients more effectively than existing measures and it is a superior predictor of locally mean reverting components of inflation

does supervision matter some hypothesis tests using indian farm level data abstract a model is developed and estimated to test for heterogeneity of family and hired labor in agricultural production and to estimate the impact of employer supervision on the productivity of hired labor plot level data are used from a rice growing village in semi arid tropical india the hypothesis that family and hired labor are homogeneous inputs was rejected results indicate that family member supervision is required to increase hired labor productivity output loss attributable to operating at reduced supervision intensity was greater than 10 on over 40 of the plots

detrending stylized facts and the business cycle the stylized facts of macroeconomic time series can be presented by fitting structural time series models within this framework we analyse the consequences of the widely used detrending technique popularised by hodrick and prescott 1980 it is shown that mechanical detrending based on the hodrick prescott filter can lead investigators to report spurious cyclical behaviour and this point is illustrated with empirical examples structural time series models also allow investigators to deal explicitly with seasonal and irregular movements that may distort estimated cyclical components finally the structural framework provides a basis for exposing the limitations of arima methodology and models based on a deterministic trend with a single break

gender and industry differences in employment cyclicality evidence over the postwar period this paper explains how cyclical patterns of employment vary between genders and across industries and how these two factors are related by gender differences in the industry distribution of workers evidence shows that men s employment is more procyclical than women s and that men s overrepresentation in highly volatile industries more than accounts for the gender gap in employment cyclicality

should central banks respond to movements in asset prices in recent decades asset booms and busts have been important factors in macroeconomic fluctuations in both industrial and developing countries in light of this experience how if at all should central bankers respond to asset price volatility we have addressed this issue in previous work bernanke and gertler 1999 the context of our earlier study was the relatively new but increasingly popular monetary policy framework known as inflation targeting see e g bernanke and frederic mishkin 1997 in an inflation targeting framework publicly announced medium term inflation targets provide a nominal anchor for monetary policy while allowing the central bank some flexibility to help stabilize the real economy in the short run the inflation targeting approach gives a specific answer to the question of how central bankers should respond to asset prices changes in asset prices should affect monetary policy only to the extent that they affect the central bank s forecast of inflation to a first approximation once the predictive content of asset prices for inflation has been accounted for there should be no additional response of monetary policy to assetprice fluctuations in use now for about a decade inflationtargeting has generally performed well in practice however so far this approach has not often been stress tested by large swings in asset prices our earlier research employed simulations of a small calibrated macroeconomic model to examine how an inflation targeting policy defined as one in which the central bank s instrument interest rate responds primarily to changes in expected inflation might fare in the face of a boom and bust cycle in asset prices we found that an aggressive inflationtargeting policy rule in our simulations one in which the coefficient relating the instrument interest rate to expected inflation is 2 0 substantially stabilizes both output and inflation in scenarios in which a bubble in stock prices develops and then collapses as well as in scenarios in which technology shocks drive stock prices intuitively inflation targeting central banks automatically accommodate productivity gains that lift stock prices while offsetting purely speculative increases or decreases in stock values whose primary effects are through aggregate demand conditional on a strong policy response to expected inflation we found little if any additional gains from allowing an independent response of central bank policy to the level of asset prices in our view there are good reasons outside of our formal model to worry about attempts by central banks to influence asset prices including the fact that as history has shown the effects of such attempts on market psychology are dangerously unpredictable hence we concluded that inflationtargeting central banks need not respond to asset prices except insofar as they affect the inflation forecast in the spirit of recent work on robust control the exercises in our earlier paper analyzed the performance of policy rules in worst case discussants robert shiller yale university glenn rudebusch federal reserve bank of san francisco kenneth rogoff harvard university

a new keynesian model with heterogeneous expectations abstract within a new keynesian model we incorporate bounded rationality at the individual agent level and we determine restrictions on expectations operators sufficient to imply aggregate is and as relations of the same functional form as those under rationality this result provides dual implications the strong nature of the restrictions required to achieve aggregation serve as a caution to researchers imposing heterogeneous expectations at an aggregate level may be ill advised on the other hand accepting the necessary restrictions provides for tractable analysis of expectations heterogeneity as an example we consider a case where a fraction of agents are rational and the remainder are adaptive and find specifications that are determinate under rationality may possess multiple equilibria in case of expectations heterogeneity

farmers health and agricultural productivity agriculture is one of the most hazardous productive sectors around the world most previous studies have focused on health issues of farmers in developing countries while little attention has been paid to farmers health problems in developed countries the present study assesses the effect of farmers health conditions on agricultural productivity in norway employing stochastic frontier regression techniques we conclude that differences in farmers health help to explain the variance in agricultural production efficiency

caste discrimination and transaction costs in the labor market evidence from rural north india abstract this paper is an empirical attempt to quantify caste based discrimination in the labor market using household data taken from rural north india in the regression analysis transaction costs associated with entry into the labor market and reservation wages are estimated simultaneously along with market wages the estimation results provide evidence of the existence of transaction costs in the labor market and discrimination against backward classes with regard to access to regular employment in line with previous studies the results suggest that the achievements of india s reservation policy so far have at best been limited in addition a comparison between the estimates from the model employed in this paper and conventional reduced form approaches shows that discrimination in labor market entry is likely to be underestimated in the conventional reduced form approaches

occupational variation in quantity quality trade off in a brawn based economy the paper revisits the theory of the quantity quality trade off and demonstrates that the relationship between quantity and health of children is subject to occupational variation in physical energ

monetary policy indeterminacy and learning abstract forward looking monetary models with taylor type interest rate rules are known to generate indeterminacies with a potential dependence on extraneous sunspots for some structural and policy parameters we investigate the stability of these solutions under adaptive learning focusing on common factor or resonance frequency representations in which the observed sunspot has a suitable time series structure we consider specifications incorporating both lagged and expected inflation in the phillips curve and both expected and inertial elements in the policy rule we find that some policy rules can indeed lead to learnable sunspot solutions and we investigate the conditions under which this phenomenon arises

endogenous persistence in an estimated dsge model under imperfect information a framework for estimating dynamic stochastic general equilibrium dsge models by bayesian methods and validation under very general information assumptions is applied to a new keynesian model the standard asssumption that private agents have perfect information observing all state variables including shocks whereas the econometrician uses only observable data is compared with both agents having the same imperfect information ii set we also generalise rational expectations to a behavioural composite model that allows some households and firms to form expectations adaptively we find significant empirical support for ii as an endogenous persistence mechanism but this is dominated by that from habit and adaptive learning

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

wage gains associated with height as a form of health human capital height is consulted as a latent indicator of early nutrition and lifetime health status height is observed to increase in recent decades in populations where per capita national income has increased and public health activities have grown height is determined by genetic make up and realized in part through satisfactory nutrition and health related care and conditions alternative instrumental variables iv are explored which proxy price and income constraints which are expected to influence the latter reproducible human capital investments in height i report ols and iv estimates of the partial effect of height on log hourly wages in recent national surveys from three countries ghana brazil and the united states i conclude that the human capital productivity effect of height estimated by parent education ivs in the us and ghana are many times larger than the ols estimates and in ghana and brazil the regional price ivs estimates also imply a substantially larger human capital wage effects of height compared with the ols estimates the ols estimates of height effects on wages are dominated by the genetic variation in height and appear to understate substantially the human capital returns to health and nutrition inputs which increase adult height this abstract was borrowed from another version of this item

heterogeneous expectations in monetary dsge models this paper derives a general new keynesian framework with heterogeneous expectations by explicitly solving the micro foundations underpinning the model the resulting reduced form is analytically tractable and encompasses the representative rational agent benchmark as a special case we specify a setup in which some agents as a result of cognitive limitations make mistakes when forecasting future macroeconomic variables and update their beliefs as new information becomes available while other agents have rational expectations we then address determinacy issues related to the use of different interest rate rules and derive policy implications for a monetary authority aiming at stabilizing the economy in a dynamic feedback system in which macroeconomic variables and heterogeneous expectations co evolve over time

heterogeneity learning and information stickiness in inflation expectations in this paper we propose novel techniques for the empirical analysis of adaptive learning and sticky information in inflation expectations these methodologies are applied to the distribution of households inflation expectations collected by the university of michigan survey research center to account for the evolution of the cross section of inflation forecasts over time and measure the degree of heterogeneity in private agents forecasts we explore time series of percentiles from the empirical distribution our results show that heterogeneity is pervasive in the process of inflation expectation formation we identify three regions of the distribution that correspond to different underlying mechanisms of expectation formation a static or highly autoregressive region on the left hand side of the median a nearly rational region around the median and a fraction of forecasts on the right hand side of the median formed in accordance with adaptive learning and sticky information

income productivity in china on the role of health this study provides empirical evidence regarding the income productivity of health human capital in china we appeal to concepts from human capital theory to support a basic model that treats health as a form of human capital in the income production process our model examines the economic return at the household level from the health of its individual members we estimate this with a longitudinal sample drawn from the china health and nutrition survey chns allowing us to exploit within variation in health and income to address possible unobservables biasing estimates of the impact of health on income in the simple cross sectional setting household income is strongly influenced by the health of its members particularly in rural areas these findings could have important implications for health and economic policy making aimed at reducing the long standing urban rural economic gap and more comprehensively insuring the rural population against health and economic risk

income inequality consumption credit and credit risk in a data driven agent based model abstract the issue of income inequality occupies a prominent position in the research agenda of academic and policy circles alike especially after the crisis of 2008 due to its potential causal link with the development of credit bubbles and therefore the emergence of financial crises this paper examines the long run effect of income inequality on consumption consumer credit and non performing loans through the means of a data driven agent based model the data driven nature of the model enhances its ability to match historical series and thus makes it suitable for policy simulations tailored for specific economies the analysis indicates that higher income inequality has a detrimental impact on consumption and is associated with lower volumes of consumer credit however the ratio of non performing loans as a share of total loans seems to be independent of income inequality

sticky information and model uncertainty in survey data on inflation expectations abstract this paper compares three reduced form models of heterogeneity in survey inflation expectations on the one hand we specify two models of forecasting inflation based on limited information flows of the type developed in mankiw and reis 2002 sticky information versus sticky prices a proposal to replace the new keynesian phillips curve quarterly journal of economics 117 4 1295 1328 we present maximum likelihood results that suggests a sticky information model with a time varying distribution structure is consistent with the michigan survey of inflation expectations we also compare these sticky information models to the endogenous model uncertainty approach in branch 2004 the theory of rationally heterogeneous expectations evidence from survey data on inflation expectations economic journal 114 497 non parametric evidence suggests that models which allow the degree of heterogeneity to change over time provide a better fit of the data

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

local convergence properties of a cobweb model with rationally heterogeneous expectations abstract this paper gives local stability conditions for convergence of the price dynamics in a cobweb model with rationally heterogeneous expectations generalizing the example of brock and hommes 1997 when agents choose between rational naive and adaptive beliefs the steady state may be locally asymptotically stable if the adaptive predictor places enough weight on past prices and is costless if adaptive expectations are sufficiently more costly than naive expectations the steady state will be an unstable saddle point our results imply that adding a choice can stabilize a system which is unstable under the brock and hommes model these results illustrate how the critical parameter that governs stability is dependent on the array of available predictors

short and medium term financial real cycles an empirical assessment 2019 elsevier ltd theories such as minsky s financial instability hypothesis or new keynesian financial accelerator models assign a key role to financial factors in business cycle dynamics we propose a simple var based estimation framework to examine some of the financial real interaction mechanisms that are at the core of these theories we examine cycle frequencies in seven oecd countries over the period 1970 2015 and find that output contains short and medium business cycle frequencies while interest rates business debt and household debt exhibit short medium and long cycles respectively we find robust evidence for financial real interaction mechanisms i at high frequencies between interest rates and gdp in australia and the usa and ii at medium frequencies between business debt and gdp in canada and great britain the effect of interest rates and debt seems to operate via investment rather than consumption we find no evidence for an interaction mechanism between household debt and gdp our results provide support for minskyan and financial accelerator models in which output interacts with interest rates or corporate debt
