do macroforecasters herd we show that typical tests of whether forecasters herd will falsely indicate herding behaviour for a variety of types of behaviour and forecasting environments that give rise to disagreement amongst forecasters we establish that forecasters will appear to herd if di erences between them reject noise as opposed to private information or if they arise from informational rigidities noise can have a behavioural interpretation and if so will depend on the behavioural model under consideration an application of the herding tests to us quarterly survey forecasts of inflation and output growth data 1981 2013 does not support herding behaviour

forecasting metal prices do forecasters herd abstract we analyze more than 20 000 forecasts of nine metal prices at four different forecast horizons we document that forecasts are heterogeneous and report that anti herding appears to be a source of this heterogeneity forecaster anti herding reflects strategic interactions among forecasters that foster incentives to scatter forecasts around a consensus forecast

bias rationality and asymmetric loss functions abstract in the literature it is a common empirical finding that survey based expectations are biased at the individual level this has sparked a large debate if forecasters have asymmetric loss functions or the rationality assumption is violated in this paper i will show that the bias can in large part be explained by the pattern of missing observations in the survey thus the assumption of asymmetric loss functions is not required to satisfy the rationality assumption

rational bias in yield curve forecasts empirical studies of forecasts often fail to reconcile the rational expectations hypothesis with a minimum mean square error objective function recent studies however have argued that observed b

inflation real economic growth and unemployment expectations an empirical analysis based on the ecb survey of professional forecasters expectations are at the centre of modern macroeconomic theory and policymakers in this article we examine the predictive ability and the consistency properties of macroeconomic expectations using

macroeconomic forecasts and microeconomic forecasters in the presence of principal agent problems published macroeconomic forecasts by professional economists may not measure expectations forecasters may use their forecasts in order to manipulate beliefs about their ability i test a cross sectional implication of models of reputation and information revelation i find that as forecasters become older and more established they produce more radical forecasts since these more radical forecasts are in general less accurate ex post forecast accuracy grows significantly worse as forecasters become older and more established these findings are consistent with reputational factors at work in professional macroeconomic forecasts

are some forecasters really better than others in any dataset with individual forecasts of economic variables some forecasters will perform better than others however it is possible that these ex post differences reflect sampling variation and thus overstate the ex ante differences between forecasters in this paper we present a simple test of the null hypothesis that all forecasters in the us survey of professional forecasters have equal ability we construct a test statistic that reflects both the relative and absolute performance of the forecaster and use bootstrap techniques to compare the empirical results with the equivalents obtained under the null hypothesis of equal forecaster ability results suggest little support for the idea that the best forecasters are actually innately better than others though there is evidence that a relatively small group of forecasters perform very poorly

changing one s mind when the facts change incentives of experts and the design of reporting protocols experts often collect and report information over time what reporting protocol elicits the most information here a principal receives reports sequentially from an agent with privately known ability who observes two signals about the state of the world the signals differ in initial quality and unlike previous work differ in quality improvement the paper finds that mind changes inconsistent reports can signal talent if a smart agent improves faster also sequential reports dominate when the principal s decision is very sensitive to information a single report dominates if the mediocre agent s signals improve faster or the agent is likely mediocre

asymmetric loss and herding behaviour of exchange rate forecasters evidence from south africa this study examines the asymmetry of the loss function for private forecasters in exchange rate forecasts of the south african rand it tests rationality under the possibility of an asymmetric loss function the results indicate less evidence of asymmetry for a horizon of 1 month but considerable evidence of asymmetry for a horizon of 3 months however the shapes of the distributions formed by estimated asymmetry parameters of sub samples for each forecaster are symmetric regardless of the forecast horizons which implies that these forecasters do not herd or antiherd in fact the results of our empirical herding test show that forecasters neither herd nor antiherd which is in sharp contrast to recent findings on antiherding for foreign exchange rates in emerging market economies our findings provide consistent evidence for a recent suggestion that antiherding might result in the rejection of rationality even under asymmetric loss functions our findings also suggest that central bank transparency m

explanations of the inconsistencies in survey respondents forecasts a comparison of the point forecasts and the probability distributions of inflation and output growth made by individual respondents to the us survey of professional forecasters indicates that the two sets of forecasts are sometimes inconsistent we evaluate a number of possible explanations and find that not all forecasters update their histogram forecasts as new information arrives this is supported by the finding that the point forecasts are more accurate than the histograms in terms of first moment prediction c 2009 elsevier b v all rights reserved

differential interpretation in the survey of professional forecasters in this paper i estimate a simple bayesian learning model to expectations data from the survey of professional forecasters i reformulate the model in terms of forecast revisions which allows one to abstract from differences in priors and to focus the analysis on the relationship between news and revisions the empirical analysis shows that there is significant heterogeneity in the interpretation of news among forecasters in particular at longer horizons while it decreases closer to the forecast target date the results also indicate a positive relationship between prior sentiment and interpretation of the signal in the sense that relatively optimistic pessimistic forecasters are likely to believe that the signal under over estimates the future realization and assign it a low high weight in the forecast revision

relationship between forest resources and economic growth empirical evidence from china abstract natural resources especially forests are critical to china s sustainable development in recent years effective utilization of forest resources has become a significant concern in china in this study on the basis of the environmental kuznets curve ekc hypothesis the relationship between forest resources and economic growth is examined using panel data from 30 provinces in china for the period 2002 2015 and the generalized method of moments gmm approach to control for potential endogeneity the empirical results indicate that with continuous economic growth the timber output and area of afforestation would at first increase and then decrease after reaching the corresponding turning points given the considerable regional gap in economic and social development three regions of china were investigated to perform a more in depth analysis evidence observed for the country and the three regions suggests an ekc for forest resources these findings indicate positive effects of china s pursuit of a more balanced growth path where forest resources would be less consumed and more actively protected

growth deforestation and the efficiency of the redd mechanism this paper assesses the long term impacts of an international transfer called the reduced emissions from deforestation and degradation redd mechanism which aims at preserving tropical forests of the recipient economy this two sector economy faces a dilemma between economic growth and deforestation the rural sector can substitute reproducible capital for agricultural land whereas the manufacturing sector only requires capital the model shows that the redd mechanism has a non monotonic effect on steady state welfares for low transfer schemes the agricultural output increases with the transfer even though less land is under cultivation for high transfer schemes the increase in the transfer may not offset the decrease in the agricultural output the open loop symmetric nash equilibrium in a dynamic deforestation game predicts that redistributing the transfer among a finite number of producers is less efficient in reducing deforestation than in the social optimum

exchange rate puzzles and distorted beliefs abstract we propose a new explanation for the foreign exchange forward premium and delayed overshooting puzzles we show that both puzzles arise from a systematic distortion in investors beliefs about the interest rate process accordingly the forward premium is always a biased predictor of future depreciation the bias can be so severe as to lead to negative coefficients in the fama regression delayed overshooting may or may not occur depending upon the persistence of interest rate innovations and the degree of misperception we document empirically the extent of this distortion using survey data for g 7 countries against the u s and find that it is strong enough to account for these irregularities

the wisdom of competitive crowds when several individuals are asked to forecast an uncertain quantity they often face implicit or explicit incentives to be the most accurate despite the desire to elicit honest forecasts such competition induces forecasters to report strategically and nontruthfully the question we address is whether the competitive crowd s forecast the average of strategic forecasts is more accurate than the truthful crowd s forecast the average of truthful forecasts from the same forecasters we analyze a forecasting competition in which a prize is awarded to the forecaster whose point forecast is closest to the actual outcome before reporting a forecast we assume each forecaster receives two signals one common and one private these signals represent the forecasters past shared and personal experiences relevant for forecasting the uncertain quantity of interest in a set of equilibrium results we characterize the nature of the strategic forecasts in this game as the correlation among the forecasters priva

inflation expectations in latin america this paper tests the rationality of inflation forecasts surveyed in mexico brazil and chile and identifies their recent formation rule there is strong evidence that forecasts are unbiased but forecasters have not been fully efficient in the use of available information the paper assesses the importance of inflation targets to anchor inflation expectations in these countries and finds that in most cases there is room for improvement in credibility

one signal two opinions strategic heterogeneity of analysts forecasts we present a model of investors acquiring forecasts from a group of investment analysts investors may pick an analyst based on his past performance in the literature it is typically assumed that agents rewards depend solely on the type they are perceived to be which leads to typical herding results in contrast here analysts rewards not only depend on their own reputation but also on the number of analysts with a similar reputation there exist two interesting types of equilibria in the first type it is optimal for investors to ignore analysts past performance even though analysts make predictions according to their best knowledge in a second type investors do use past performance to select analysts however this induces analysts to predict strategically i e some analysts knowingly make wrong predictions

survey measures of expected u s inflation of real interest rates and cash flows for decisions concerning investment expenditures international capital flows and exchange rate movements hinge in large part on expected real yield differentials across countries the federal reserve needs reliable measures of expected inflation to formulate and gauge the thrust of monetary policy in fact inflation expectations have become more important to the fed given the diminished stability of the link between the monetary aggregates and gdp expenditures since the early 1980s and the greater role which has been thrust upon expected real short term interest rates in the implementation of federal reserve policy the issue of rationality of inflation expectations that is the extent to which agents form expectations without making systematic mistakes in their beliefs about what inflation will be is important if inflation expectations are formed rationally labor and financial markets will strongly tend to neutralize the potential redistributive effects of inflation over time financial capital will flow efficiently within and across national borders moreover some of the stronger claims of new classical macroeconomics like the claim that only unexpected monetary policy actions will

information rigidity and the expectations formation process a simple framework and new facts we propose a new approach to test the full information rational expectations hypothesis which can identify whether rejections of the null arise from irrationality or limited information this approach quantifies the economic significance of departures from the null by quantifying the underlying degree of information rigidity applying this approach to u s and international data of professional forecasters and other agents yields pervasive evidence consistent with models of imperfect information furthermore the proposed approach sheds new light on policies such as inflation targeting and those leading to the great moderation affecting expectations finally we document evidence of state dependence in the expectations formation process

bias in federal reserve inflation forecasts is the federal reserve irrational or just cautious abstract inflation forecasts of the federal reserve seem to have systematically under predicted inflation from the fourth quarter of 1968 until volcker s appointment as chairman and to systematically over predict it afterwards until the second quarter of 1998 furthermore under quadratic loss commercial forecasts seem to have information not contained in those forecasts to investigate the cause of this apparent irrationality this paper recovers the loss function implied by federal reserve s inflation forecasts the results suggest that the cost of having inflation above an implicit time varying target was larger than the cost of having inflation below it for the period since volcker and that the opposite was true for the pre volcker era once these asymmetries are taken into account the federal reserve s inflation forecasts are found to be rational

oil and the macroeconomy since world war ii all but one of the u s recessions since world war ii have been preceded typically with a lag of around three fourths of a year by a dramatic increase in the price of crude petroleum this does not mean that oil shocks caused these recessions evidence is presented however that even over the period 1948 72 this correlation is statistically significant and nonspurious supporting the proposition that oil shocks were a contributing factor in at least some of the u s recessions prior to 1972 by extension energy price increases may account for much of post opec macroeconomic performance

rational bias in macroeconomic forecasts do professional forecasters provide their true unbiased estimates or do they behave strategically in our model forecasters have common information confer actively and thus know the true pdf of future outcomes intensive users of economic forecasts monitor forecasters performance closely occasional users are drawn to the forecaster who fared best in the previous period in the resulting nash equilibrium even though economists have identical expectations they make a range of projections that mimics the true probability distribution of the forecast variable those whose wages depend most on publicity produce forecasts that differ most from the consensus empirical evidence supports the model

disclosure standards and market efficiency evidence from analysts forecasts abstract this paper studies whether recent international transparency initiatives affect information accuracy and dispersion i show that the impact of these initiatives is limited because public disclosure crowds out private investments in information i first develop a theoretical model of the incentive to invest in information and the impact of public disclosure i then analyze stock market analysts forecasts for thirty developing economies for the period 1990 2004 i find that disclosure standards enhance forecast accuracy directly but at the same time reduce the number of analysts per stock proxy for private information investments the net effect of disclosure standards thus ranges from weak to nonexistent

financial markets forecasts revisited are they rational stubborn or jumpy this paper evaluates professional forecasters behavior using a panel data of individual forecasts we find that i professional forecasts are behavioral and ii there exists a stock bond dissonance the forecasting behavior seems to be stubborn in the stock market but jumpy in the bond market even in the same country forecasting behavior is quite different by market

modelling the general public s inflation expectations using the michigan survey data in this article we discuss a few models developed to explain the general public s inflation expectations formation and provide some relevant estimation results furthermore we suggest a simple bayesian learning model which could explain the expectations formation process on the individual level when the model is aggregated to the population level it could explain not only the mean values but also the variance of the public s inflation expectations the estimation results of the mean and variance equations seem to be consistent with the results of the questionnaire studies in which the respondents were asked to report their thoughts and opinions about inflation

disagreement and biases in inflation expectations empirical work documents substantial disagreement in inflation expectations obtained from survey data furthermore the extent of such disagreement varies systematically over time in a way that reflects the level and variance of current inflation this paper oers a simple explanation for these facts based on asymmetries in the forecasters costs of over and under predicting inflation our model implies biased forecasts with positive serial correlation in forecast errors and a cross sectional dispersion that rises with the level and the variance of the inflation rate it also implies that forecast errors at dierent horizons can be predicted through the spread between the short and long term variance of inflation we find empirically that these patterns are present in inflation forecasts from the survey of professional forecasters a constant bias component not explained by asymmetric loss and rational expectations is required to explain the shift in the sign of the bias observed for a substantial portion of forecasters around 1982

a theory of noise trading in securities markets in a recent article black 1 introduces a type of trading that he terms noise trading he asserts that noise trading which he defines as trading on noise as if it were information must be a significant factor in securities markets however he does not provide an explanation of why any investors would rationally want to engage in noise trading the goal of this paper is to provide such an explanation for one type of investor managers of investment funds as shown here the incentive for a manager to engage in noise trading arises because of the positive signal that the level of the manager s trading provides about his or her ability to collect private information concerning current and potential investments if the manager s compensation is directly related to investors perceptions of his or her ability the manager will then trade more frequently than is justified on the basis of his or her private information in addition to providing this explanation for noise trading the results of this analysis may also be useful for further empirical exploration of the relation between investment fund portfolio turnover and subsequent performance

why are professional forecasters biased agency versus behavioral explanations professional forecasters may not simply aim to minimize expected squared forecast errors in models with repeated forecasts the pattern of forecasts reveals valuable information about the forecasters even before the outcome is realized rational forecasters will compromise between minimizing errors and mimicking prediction patterns typical of able forecasters simple models based on this argument imply that forecasts are biased in the direction of forecasts typical of able forecasters our models of strategic bias are rejected empirically as forecasts are biased in directions typical of forecasters with large mean squared forecast errors this observation is consistent with behavioral explanations of forecast bias

an analysis of a panel of spanish gdp forecasts this article undertakes an analysis of the forecasts included in the panel of spanish forecasts in order to highlight the fact that the predictions made and the errors committed by the entities participating on this panel contain information that is particularly useful in analysing the evolution of the spanish economy here a study is undertaken of the gdp growth forecasts for the spanish economy for the period 2000 to 2002 made in distinct forecast time horizons specifically it analyses whether the forecasts are optimistic or pessimistic and whether new information concerning the variable being predicted is used efficiently in revising earlier forecasts

extreme weather experiences and climate change beliefs in china an econometric analysis this paper examines the extent and the determinants of global climate change beliefs in contrast to former studies for the u s and other western countries we focus on china due to its crucial role in international climate policy in conjunction with its vulnerability to global warming the empirical analysis is based on unique data from a survey among more than 1000 adults in five chinese cities in line with former studies our results reveal that the vast majority of almost 90 of the chinese respondents believes in the existence of global warming this seems to be a convenient and necessary basis for the support of costly public adaptation activities in china our econometric analysis reveals that already perceived experiences with extreme weather events and particularly heatwaves alone are strongly correlated with climate change beliefs and that physical or financial damages due to these events lead to even stronger relationships our estimation results additionally suggest females as well as people with a lower education in medium ages with higher household incomes and from chengdu or shenyang to be more skeptical toward the existence of climate change

testing for forecast consensus a panel of forecasts may be defined to be in consensus when individual forecasters place identical weights on a common latent variable we suggest this definition and formulate a dynamic latent variable model to test for consensus this method also tests whether it is valid to use the mean forecast as the consensus forecast in applications to surveys of u s macroeconomic forecasters there is greater consensus in forecasts for output growth than for inflation or unemployment but idiosyncratic forecast autocorrelation from year to year is present for most forecasters

federal reserve information and the behavior of interest rates this paper tests for the existence of asymmetric information between the federal reserve and the public by examining federal reserve and commercial inflation forecasts it demonstrates that the federal reserve has considerable information about inflation beyond what is known to commercial forecasters it also shows that monetary policy actions provide signals of the federal reserve s information and that commercial forecasters modify their forecasts in response to those signals these findings may explain why long term interest rates typically rise in response to shifts to tighter monetary policy jel e52 e43 d82 asymmetric information between the federal reserve and the public is a phenomenon that is often posited but rarely tested numerous models of central bank behavior for example show that the existence of asymmetric information has important implications for the effectiveness of policy and the consequences of dynamic inconsistency yet there

competition and bias we attempt to measure the effect of competition on bias in the context of analyst earnings forecasts which are known to be excessively optimistic because of conflicts of interest our natural experiment for competition is mergers of brokerage houses which result in the firing of analysts because of redundancy e g one of the two oil stock analysts is let go and other reasons such as culture clash we use this decrease in analyst coverage for stocks covered by both merging houses before the merger the treatment sample to measure the causal effect of competition on bias we find that the treatment sample simultaneously experiences a decrease in analyst coverage and an increase in optimism bias the year after the merger relative to a control group of stocks consistent with competition reducing bias the implied economic effect from our natural experiment is significantly larger than estimates from ols regressions that do not correct for the endogeneity of coverage this effect is much more significant for stocks with little initial analyst coverage or competition

rational expectations in the aggregate this paper investigates the relationship between the way rational expectations is employed in practice and the argument initially put forth to justify its use in practice rational expectations has meant that the expectations of each agent taken separately is consistent with the predictions of the theory this is different than the argument frequently used by proponents of rational expectations that on an aggregate level expectations should be consistent with the theory the primary findings are that standard and aggregate rational expectations typically yield systematically different equilibria and that the size of the difference depends positively on the degree of synergism

on the internal consistency of short term medium term and long term oil price forecasts we derive internal consistency restrictions on short medium and long term oil price forecasts we then analyse whether oil price forecasts extracted from the survey of professional forecasters spf conducted by the european central bank ecb satisfy these internal consistency restrictions we find that neither short term forecasts are consistent with medium term forecasts nor that medium term forecasts are consistent with long term forecasts using a more complex expectation formation structure featuring a distributed lag structure however we find stronger evidence of internal consistency of medium term forecasts with long term forecasts

ecotourism demand and differential pricing of national park access in costa rica ecotourism presents developing countries with growing opportunities for enhancing resource conservation and economic growth but also raises pressing management and policy challenges this paper presents a conceptual framework and empirical analysis of the impacts of introducing a differential entrance fee policy at three national parks in costa rica data are collected using a contingent behavior methodology designed to elicit information on foreign tourists hypothetical park visitation behaviors at alternative entrance fee levels park visitation demand functions and price and income elasticities are estimated revenue maximizing fees are calculated and applications of differential pricing principles to park management are discussed

paying for mitigation a multiple country study a contingent valuation study conducted in china sweden and the united states was used to investigate citizens willingness to pay wtp for reducing co2 emissions we find that a majority of the respondents in all three countries believe that the mean global temperature has increased over the last 100 years and that humans are responsible for the increase the share of americans that believes these statements is smaller and a relatively larger share of americans also believes that nothing can be done to stop climate change sweden has the highest wtp while china has the lowest jel q51 q54

forecasting stock prices do forecasters herd abstract we use the livingston survey data to study whether forecasters of the s p 500 stock price index herd our results imply that forecasters do not herd rather we find that forecasters anti herd anti herding is less prevalent among academics and federal reserve economists forecaster anti herding is inversely correlated with forecast accuracy forecaster anti herding is not correlated with age

new evidence of anti herding of oil price forecasters abstract we used the oil price forecasts of the survey of professional forecasters published by the european central bank to analyze whether oil price forecasters herd or anti herd oil price forecasts are consistent with herding anti herding of forecasters if forecasts are biased towards away from the consensus forecast based on a new empirical test developed by bernhardt et al j financ econ 80 657 675 2006 we found strong evidence of anti herding among oil price forecasters

do professional forecasters trust in taylor type rules evidence from the wall street journal poll this article uses the monthly wall street journal poll between 2002 and 2010 to analyse whether professional economic forecasters believe in and thus apply taylor type rules for their own forecasts using their forecasts for the federal funds rate the inflation rate and capacity utilization we estimate whether these are internally consistent with the message of taylor type rules we find that the expectation formation can indeed be described by taylor type rules

explaining bureaucratic optimism theory and evidence from u s executive agency macroeconomic forecasts we offer a theory of intertemporal bureaucratic decision making which proposes that an agency s forecast optimism is related to the extent to which it discounts future reputation costs associated with bureaucratic incompetence agency forecasts of the distant future are more likely to be optimistic than short term forecasts we claim that unstable organizations will discount reputation costs at a steeper rate than stable organizations and therefore will produce more optimistic forecasts we test our theory using macroeconomic forecasts produced by the office of management and budget omb and the social security administration ssa across six forecast horizons from 1979 to 2003 the statistical results are generally consistent with our theory omb generates more optimistic long term forecasts than ssa further differences in forecast optimism between these executive branch agencies widen as the forecast horizon increases our evidence suggests that more stable agencies place a premium on minimizing reputation costs conversely less stable agencies are more likely to accommodate political pressures for forecast optimism these findings underscore the importance of institutional design for understanding how executive agencies balance the conflicting goals of political responsiveness and bureaucratic competence within the administrative state

how beliefs influence the willingness to contribute to prevention expenditure we study how beliefs affect individuals willingness to contribute to prevention expenditure through a two type n person public good game and test several results empirically we show analytically that pessimistic agents will invest more in prevention expenditure than optimists we also demonstrate how small differences in beliefs may induce substantial differences in type related prevention expenditure the more atomistic agents are the less they will contribute to the public good pessimistic beliefs then lead to a double deprivation and we discuss potential issues and remedies the more optimistic a society is the lower will be its total green expenditure we then use a large international survey to study how beliefs and additional controls determine prevention expenditure we rely on several proxies for beliefs and the willingness to contribute to prevention expenditure which we combine through principal component analysis in addition we investigate the role of environmental education for the relationship between beliefs and the willingness to contribute because of potential endogeneity bias due to unobserved variables that are likely to affect both beliefs and the willingness to contribute we follow the theoretical analysis and resort to a recursive bivariate model our main findings are very much in line with the theoretical predictions we find across all specifications that more optimistic beliefs lead to a lower willingness to contribute environmental education affects the willingness to contribute only indirectly through its impact on beliefs

political orientation environmental values and climate change beliefs and attitudes an empirical cross country analysis abstract based on unique data from representative computer based surveys among more than 3400 citizens this paper empirically examines the determinants of several climate change beliefs and attitudes in three countries which are key players in international climate policy namely the usa germany as the largest country in the european union and china our econometric analysis implies that political orientation in the usa is by far more relevant for general climate change beliefs and beliefs in anthropogenic climate change than in germany and china furthermore us and german citizens with a conservative but not green identification significantly less often support publicly financed climate policy while us and german respondents with a social green identification and chinese respondents belonging to the communist party have a significantly higher willingness to pay a price premium for climate friendly products however our econometric analysis overall reveals that environmental values which are measured by a new ecological paradigm nep scale are the major factors for climate change beliefs and attitudes in all three countries and thus play an even more dominant role than political orientation in addition environmental values weaken the differences in several climate change beliefs and attitudes between a right wing and a left wing identification these interaction effects between political orientation and the nep scale are especially strong in the usa only relevant for the support of publicly financed climate policy in germany and negligible in china our estimation results suggest alternative strategies such as specific communication campaigns in order to reduce the climate change skepticism in conservative and right wing circles in the usa and to increase the support of climate policies among such population groups

uncertainty and currency crises evidence from survey data this paper studies empirically how uncertainty aects speculation in the foreign ex change markets we use the dispersion of survey forecasts of key macroeconomic variables to measure uncertainty about fundamentals we nd that uncertainty has a non monotone eect on exchange rate pressures namely uncertainty heightens speculative pressures when expected fundamentals are good and eases them when they are bad we prove that this prediction arises from a broad class of currency crisis theories ranging from rst generation to global game models we also show that the proposed empirical strategy remains valid in the presence of forecasters with strategic objectives and use a novel set of instrumental variables to address potential endogeneity bias

economic prosperity biodiversity conservation and the environmental kuznets curve many conservationists contend that economic growth and biodiversity conservation are incompatible goals some economists contest this viewpoint arguing that wealthier countries have the luxury of investing more heavily in efforts to conserve biodiversity under this assumption we expect a u shaped relationship between per capita wealth and proportion of species conserved we test this environmental kuznets curve ekc using estimates of per capita income and deforestation rates index of biodiversity threat for 35 tropical countries a prior analysis dietz s adger w n 2003 economic growth biodiversity loss and conservation effort journal of environmental management 68 23 35 using conventional regression techniques failed to provide any support for the parabolic relationship predicted by the ekc hypothesis here we introduce the use of quantile regression and spatial filtering to reanalyze this data addressing issues of heteroskedasticity and spatial autocorrelation we note that preliminary analysis using these methods provides some initial evidence for an ekc however a series of panel analyses with country specific dummy variables eliminated or even reversed much of this support a closer examination of conservation practices and environmental indicators within the countries particularly those countries that drove our initial support suggests that wealth is not a reliable indicator of improved conservation practice our findings indicate that an ekc for biodiversity is overly simplistic and further exploration is required to fully understand the mechanisms by which income affects biodiversity

biases in macroeconomic forecasts irrationality or asymmetric loss empirical studies using survey data on expectations have frequently observed that forecasts are biased and have concluded that agents are not rational we establish that existing rationality tests are not robust to even small deviations from symmetric loss and hence have little ability to tell whether the forecaster is irrational or the loss function is asymmetric we quantify the exact trade off between forecast inefficiency and asymmetric loss leading to identical outcomes of standard rationality tests and explore new and more general methods for testing forecast rationality jointly with flexible families of loss functions that embed quadratic loss as a special case an empirical application to survey data on forecasts of nominal output growth demonstrates the empirical significance of our results and finds that rejections of rationality may largely have been driven by the assumption of symmetric loss

moving beyond commitments creating durable change through the implementation of asia pulp and paper s forest conservation policy abstract campaigns by non governmental organizations ngos pressuring companies to adopt sustainability standards have caught academic interest in recent years critics of this approach toward increasing biodiversity protection and social justice argue that campaign successes are often short lived while proponents emphasize the potential of ngo campaigns to achieve positive environmental and social change in the absence of governmental legislation focusing on the recent forest conservation policy of asia pulp and paper app a leading pulp and paper company operating in southeast asia we analyze the challenges companies face in implementing sustainability commitments made as a result of ngo and market pressure drawing from research on policy implementation and corporate greening we identify key activities to help entrench app s commitments in the company s operations furthermore we suggest that a range of actions by different stakeholder groups can achieve broader effects of app s commitments toward better environmental and social stewardship in the region s pulp and paper sector

the strategy of professional forecasting we develop and compare two theories of professional forecasters strategic behavior the first theory reputational cheap talk posits that forecasters endeavor to convince the market that they are well informed the market evaluates their forecasting talent on the basis of the forecasts and the realized state if the market expects forecasters to report their posterior expectations honestly then forecasts are shaded toward the prior mean with correct market expectations equilibrium forecasts are imprecise but not shaded the second theory posits that forecasters compete in a forecasting contest with pre specified rules in a winner take all contest equilibrium forecasts are excessively differentiated

testing the rationality of price forecasts new evidence from panel data this paper tests the rationality of individual price forecasts in a panel of professional forecasters here unlike in most previous studies rationality is not rejected the results here differ because 1 using individual forecasts avoids aggregation bias 2 comparison of forecasts to initial data avoids bias due to data revision 3 the professional forecasters have economic incentives to state their expectations accurately and 4 a new covariance matrix estimator consistent when forecast errors are correlated across individuals is used copyright 1990 by american economic association

do sell side stock analysts exhibit escalation of commitment this paper presents evidence that when an analyst makes an out of consensus forecast of a company s quarterly earnings that turns out to be incorrect she escalates her commitment to maintaining an out of consensus view on the company relative to an analyst who was close to the consensus the out of consensus analyst adjusts her forecasts for the current fiscal year s earnings less in the direction of the quarterly earnings surprise on average this type of updating behavior reduces forecasting accuracy so it does not seem to reflect superior private information further empirical results suggest that analysts do not have financial incentives to stand by extreme stock calls in the face of contradictory evidence managerial and financial market implications are discussed

the role of media for inflation forecast disagreement of households and professional forecasters this paper investigates the effects of media coverage about consumer price inflation on inflation forecast disagreement of german households and professional forecasters we adopt a bayesian learning model in which media coverage of inflation affects forecast disagreement by influencing information sets as well as predictor choice our empirical results show that disagreement of households depends on the heterogeneity of story content and on the reporting intensity especially of news on rising inflation disagreement of professional forecasters does not depend on media coverage with respect to the influence of macroeconomic variables we provide evidence that disagreement of professional forecasters primarily depends on the inflation rate and on inflation volatility the response of households to inflation is much less pronounced

foreign exchange rate expectations micro survey data this paper analyzes the panel data of biweekly surveys on the yen dollar exchange rate expectations of forty four institutions for two years and contains four major findings first market participants are heterogeneous that is significant individual effects exist in their expectation formation second the individual effects have a characteristic of wishful expectations exporters expect yen depreciation and importers expect yen appreciation relative to others third many violate the rational expectations hypothesis fourth forecasts with long horizons show less yen appreciation than those with short horizons cross equation constraints implied by the consistency of the forecast term structure are strongly rejected in the data copyright 1990 by american economic association

exchange rate expectations the role of person specific forward looking variables abstract we analyze how individual forecasters build their foreign exchange rate expectations the wall street journal poll allows us to incorporate explanatory variables such as expected inflation rates and expected gdp growth rates that are both forward looking and person specific

economic growth and liquidation of natural capital the case of forest clearance the importance of natural capital to economic systems is increasingly recognized previous empirical models of economic growth rates however have emphasized accumulation of physical and human capital this paper shows that the economic growth of over 70 countries has been positively affected by liquidation of one aspect of natural capital forests while controlling for factors typically associated with national growth rates the positive association was robust to additions of various covariates such as forest exports level of economic development agricultural area and geographical position these results suggest that conversion of forests has partially fuelled the economic expansion of countries

testing the rationality of price forecasts reply carl bonham and richard cohen 1995 are quite correct in noting the errors in our paper keane and runkle 1990 which were caused by our ignorance of cointegration we stand chagrined however bonham and cohen are overstating their case when they claim that keane and runkle s results do not support the empirical validity of the rational expectations hypothesis p 289 bonham and cohen focus on our tests of price forecast rationality conditioned on past oil prices and ml which they claim are the core of our paper and provide our most stringent tests of rationality those particular tests account for only two paragraphs of our 20 page paper obviously these tests do not provide the core results of our paper rather the main result of our paper is that individual price forecasts are unbiased and rational conditioned on the forecaster s own past errors no previous researchers had ever found even this limited support for the rational expectations hypothesis these core results are unaffected by the cointegration issues noted by bonham and cohen given that caveat however note how few of our results are actually overturned by bonham and cohen although our test statistics for determining whether forecasters properly condition on ml growth are incorrect bonham and cohen reach the same conclusion that we do price forecasts conditioned on ml growth are rational bonham and cohen do reach different conclusions about forecast rationality than we do when they condition on oil price changes but they themselves show that forecasters were only irrational in conditioning on oil prices after 1973 their table 2 rows 5 and 6 to call such forecasting failure irrationality may or may not be correct we think that bonham and cohen s results merely confirm the widespread view that forecasters did not completely understand the effects that oil price shocks would have on the economy because such large oil price shocks had never been seen before although bonham and cohen overturn only one of our original tests they do provide additional evidence against forecast rationality with their tests that condition on interest rate spreads and the unemployment rate we have no doubt that a search over a large number of conditioning variables will uncover some instances in which forecast rationality is rejected but conducting such a search will also incorrectly bias tests toward rejecting rationality since our original paper we have also examined the rationality of earnings forecasts made by individual stock analysts a group that has even more incentive than economic forecasters to make accurate predictions although all previous studies in that literature had found individual earnings forecasts to be irrational we found keane and runkle 1994 that analysts forecasts are rational this additional research provides further support for the paper criticized by bonham and cohen

does competition induce analyst effort evidence from a natural experiment of broker mergers abstract hong and kacperczyk 2010 document that decreases in analyst competition due to broker mergers encourage analysts to please managers leading to greater consensus optimism bias we propose three additional effects of analyst competition the analyst effort hypothesis suggests that weaker competition reduces analysts incentives to collect and analyze information the herding hypothesis argues that weaker competition reduces analysts career concerns which in turn reduces herding incentives the strategic deviation hypothesis implies that weaker competition alleviates analysts incentives to strategically deviate from others we find that after broker mergers analysts follow fewer firms and switch their coverage from firms with more to those with less r d expenses they weigh their private information less when it is unfavorable at the same time their forecasts become more dispersed all these findings appear to be more consistent with the analyst effort hypothesis than the herding or strategic deviation hypothesis

can rational stubbornness explain forecast biases this paper examines whether the rational jumpiness stubbornness hypothesis can explain forecast biases using a dataset of professional gdp forecasts for the g7 countries over the period 1989 2010 we find evidence supporting the rational stubbornness hypothesis specifically forecasters underreact more when large forecast revisions are highly indicative of low forecast ability underreaction is less likely when the size of forecast revisions is unrelated to ability these findings are consistent with the hypothesis that forecasters choose to smooth gdp forecasts to maximize their perceived ability

evaluating the efficiency of the fomc s new economic projections since 2007 fomc policymakers have been publishing detailed numerical projections of macroeconomic series over the next three years by testing whether the revisions to these projections are unpredictable i find that fomc s efficiency is generally accepted for inflation but often rejected for real economic variables notably for the unemployment rate the rejection is due to the strong autocorrelation of revisions which may reflect information rigidity of fomc s unemployment projections the joint efficiency of the entire projection is accepted in most cases

consensus and uncertainty in economic prediction we define consensus as the degree of agreement among point predictions aimed at the same target by different individuals and uncertainty as the diffuseness of the corresponding probability distributions this distinction is made operational with the aid of the nber asa survey data on matched point and probabilistic forecasts of inflation and the rate of change in gross national product the means of the two sets of forecasts agree closely standard deviations of point forecasts tend to understate uncertainty as measured by standard deviations of the predictive probability distributions however these measures of consensus and uncertainty are on the whole positively correlated there is evidence that expectations of higher inflation generate greater uncertainty about inflation tests also favor the hypothesis that a rise in inflation uncertainty has adverse effects on real growth

the rationality of usda forecasts under multivariate asymmetric loss a large number of previous studies suggest that many usda forecasts are biased and or inefficient these findings however may be the result of the assumed loss function of usda forecasters we test the rationality of the usda net cash income forecasts and the wasde production and price forecasts between 1988 and 2018 using a flexible multivariate loss function that allows for asymmetric loss and non separable forecast errors our results provide robust evidence that usda forecasters are rational expected loss minimizers yet demonstrate a tendency to place a greater weight on under or overprediction as a result this study provides an alternate interpretation of previous findings of forecast irrationality

expectations and the quantity equation evidence from eastern european countries this article analyses the usefulness of the quantity equation from the financial market s view we use more than 10 000 forecasts of financial analysts concerning projections of the growth rate of money supply prices and real output for six central and eastern european countries to test whether they are internally consistent with the quantity equation in particular we report that forecasts are consistent with the quantity equation in high inflation countries and high inflation regimes

oil price forecasting under asymmetric loss based on the approach developed by elliott et al 2005 we found that the loss function of a sample of oil price forecasters is asymmetric in the forecast error our findings indicate that the loss oil price forecasters incurred when their forecasts exceeded the price of oil tended to be larger than the loss they incurred when their forecast fell short of the price of oil accounting for the asymmetry of the loss function does not necessarily make forecasts look rational

testing the rationality of japanese gdp forecasts the sign of forecast revision matters abstract this paper analyzes the rationality of japanese gdp forecasts of individual economists it finds that japanese forecasters are pessimistic optimistic when their forecast revisions frs are positive negative and that they always over react to new information across forecasters the magnitude of average fr is not correlated with the magnitude of average forecast errors fe these results together are consistent with neither the rational expectations hypothesis nor reputation models with rational and strategic forecasters

differences in relative prices and international differences in growth rates the new growth literature following paul m romer 1986 and robert e lucas jr 1988 has formulated models in which growth rates can differ systematically across countries a large empirical literature has used cross sectional techniques to examine the cause of international differences in growth rates this paper examines whether this work has used data which have been constructed in such a way as to introduce inadvertently a spurious correlation between growth and income levels this effect occurs because relative prices evolve because of different rates of technological progress in different industries many of the new growth models assume single goods or goods produced by the same technology so this phenomenon has so far escaped analysis if technological progress is more rapid in some sectors than others relative prices will change during the process of development the change of relative prices has two effects on measured growth rates first the choice of base prices affects the growth rate this phenomenon is sometimes called the gerschenkron effect second using any base prices or weights introduces a spurious correlation between income and growth less developed countries would tend to have lower growth rates not because they grew more slowly but because of data construction techniques for the sake of simplicity these phenomena will be called the gerschenkron or the level effect and the spurious correlation effect 3 this paper examines the international comparison program icp and the penn world tables pwt which are based on the icp the penn world tables are the data most widely used in empirical studies of international differences in economic growth both the icp and pwt use international prices to adjust for differences in the purchasing power of currencies these prices most closely resemble hungarian prices using such prices tends to produce time series with lower growth rates than those in the national accounts for countries less developed than hungary conversely the growth rates would be higher for countries more developed than hungary however the growth rates of poorer countries are not systematically lower in the penn world tables the paper examines why the growth rates are not distorted and makes some specific recommendations for data construction and use virginia polytechnic institute and state university blacksburg va 24061 0316 part of this work was supported by a grant from the institute of international studies at brown university and by a summer internship at the division of international finance at the federal reserve board i am grateful to peter garber david weil oded galor and anonymous referees for helpful comments alan heston and robert summers have also helped me understand icp and pwt methodology of course i alone am responsible for any mistakes in this paper iexamples include steve dowrick and duc tho nguyen 1989 robert j barro 1991 j bradford de long and lawrence h summers 1991 and n gregory mankiw et al 1992 2a series of papers by christina d romer 1986a b 1989 has already emphasized the importance of data construction techniques in another context 3there is a third effect a real acceleration effect caused by shifting consumption patterns and the reallocation of resources between sectors growth accountants such as angus maddison 1987 adjust estimates of total factor productivity for this sort of shift william j baumol et al 1989 have also referred to this phenomenon for an analysis in terms of a simple multisector solow model see nuxoll 1992a

lies damn lies and pre election polling in this paper we ask the question how well do pre election polls forecast the actual results of elections in the united states 1 the question is interesting for a number of reasons first even polling data suggest about one third of polling respondents do not believe that polls work in the best interests of the general public 2 the situa tion is such that even many national governments have undertaken to restrict some aspect of pre election polling a 1997 international survey of governments found 30 of 78 surveyed nations had some kind of ban on publication of poll results second there is a strong presumption in the lit erature on professional forecasting in other con texts such as interest rate forecasting which do not rely on sampling per se that forecasts will be biased there is a variety of explanations for why forecasts will be biased one honest motivation is that pollsters may avoid reporting results from the unavoidable atypical polls third in the literature in economics it is sometimes assumed
