the relative forecasting performance of the divisia and simple sum monetary aggregates this paper provides direct evidence on the forecasting performance of the divisia monetary aggregates relative to the traditional simple sum monetary aggregates it is shown that forecasts of u s real gdp from a four variable vector autoregression var are most accurate when a divisia aggregate is used rather than a simple sum aggregate particularly at broad levels of aggregation further the two m1 aggregates relative to the broader aggregates are superior predictors of the gdp deflator with a slight edge going to divisia m1 over simple sum m1

the demand for assets through a low interest rate environment asset demand is important in many areas of economics to investigate this we estimate a globally flexible dynamic fourier asset demand specification and calculate morishima elasticities of substit

a revealed preference test of rationing abstract this paper derives a revealed preference test for utility maximization under rationing and can detect for which goods rationing is binding without specifying a functional form or imposing rationing constraints prior to estimation for uk data from 1920 55 we find evidence of utility maximization under rationing with rationing binding for food and other services estimated virtual prices exceed observed food prices by 16 5 in 1947 and observed prices of other services by 10 9 in 1952

the changing empirical definition of money some estimates from a model of the demand for money substitutes interest bearing checkable deposits are examined to test whether they should be included in measures of the u s money stock both divisia and traditional simple sum aggregates are constructed on the basis of tests for weak separability in a model of the demand for financial assets using nonparametric demand analysis we find that several groups of assets are compatible with aggregation theory we find empirical support for a narrow measure consisting of the components of current mia in tests based on a st louis equation and in terms of controllability a divisia aggregate performs better than the simple sum mia measure

bureaucratic behavior in the local public sector a revealed preference approach public sector bureaucratic utility is typically assumed to be a function ofbudget size or government employment although intuitively appealing thereare no definitive direct tests of the assumption to fill this gap thispaper exploits data that isolate resource allocation decisions made by localpublic sector bureaucrats we use revealed preference theory to find thatthe bureaucracy behaves as if bureaucratic utility is an increasingfunction of employment across government functions and public spending providing direct evidence justifying the popular assumption in theoreticalmodels of government behavior

the egyptian farm labor market revisited abstract egyptian evidence loomed large in the old debate between proponents of surplus labor and their neo classical critics the paper uses the recent experience of this labor market to revisit the issues the unprecedented changes engendered by the oil boom basically confirm the neo classical view one may discern the following stylized facts of the egyptian farm labor market 1 both supply and demand for labor are inelastic with respect to the wage 2 real wages are very flexible rising and then falling sharply with international oil prices 3 supply shifts explain these real wage changes 4 these are in turn primarily the outcome of international labor migration 5 regional wage disparities remained roughly constant during the past decade the conclusion draws some implications for poverty alleviation and for the political economy question of how the benefits of the regional oil boom were shared

an analysis of substitution bias in measuring inflation 1959 851 we analyze the substitution bias in laspeyres type price indexes such as the cpi using 1959 1985 nipa consumption data for 101 commodities we employ two methodological approaches to calculation of the bias first we construct the tightest theoretical bounds on the col by applying nonparametric methods using algorithms developed by afriat and by varian second following diewert we construct superlative price index formulas namely tomqvist and fisher s ideal indexes under a chain as well as a fixed base specification homothetic preferences are found to be consistent with the data and sensitivity tests indicate that this result is not vacuous if the hypothesis of homotheticity is maintained the col bias has upper and lower limits of 0 22 and 0 14 percent per year respectively using the superlative indexes as the measure of the col the bias is about 0 18 percent per year for the period 1959 85 this estimate is somewhat larger than found in earlier studies our use of more disaggregated data is found to be responsible for part of the difference with the size of the estimated bias directly related to the extent of the aggregation

a comparison of nonparametric tests of weak separability for annual and quarterly data on consumption leisure and money among the most fundamental assumptions made in economics are utility maximization and the separability of the arguments in the representative consumer s utility function these assumptions are important for theoretical and empirical applications of economics in this article we present results from nonparametric tests of these assumptions of consumer behavior we find that utility maximization generally obtains with either annual or quarterly per capita data on consumption goods leisure and relatively liquid monetary assets annual data on consumption goods leisure and all monetary assets are consistent with utility maximization there is some evidence in support of using partial adjustment models when estimating quarterly data models of the demand for monetary assets further annual data on consumption goods and leisure and on liquid monetary assets meet the necessary and sufficient conditions for weak separability these results support the notion of a monetary aggregate more broadly based than cu

evaluating predictions of change this article applies a technique developed by robert c merton 1981 and roy d henriksson and robert c merton 1981 for evaluating the market timing of financial managers to macroeconomic predictions of change this methodology may be used to determine whether the predictions may be of value to the user as an illustration the methodology is applied to a set of real gross national product forecasts copyright 1990 by the university of chicago

opening the black box of intra household decision making theory and non parametric empirical tests of general collective consumption models we provide revealed preference tests of general collective consumption models that account for public consumption and externalities within the household we further propose a novel approach to model special cases of this model which imply alternative assumptions regarding the sharing rule our application uses the panel data from the russia longitudinal monitoring survey we find that the general model together with a large class of special cases cannot be rejected by contrast we do reject the standard unitary model since our tests are entirely nonparametric this provides strong evidence in favor of models focusing on intrahousehold decision making

are choice experiments incentive compatible a test with quality differentiated beef steaks this study compares hypothetical and nonhypothetical responses to choice experiment questions we test for hypothetical bias in a choice experiment involving beef ribeye steaks with differing quality attributes in general hypothetical responses predicted higher probabilities of purchasing beef steaks than nonhypothetical responses thus hypothetical choices overestimate total willingness to pay for beef steaks however marginal willingness to pay for a change in steak quality is in general not statistically different across hypothetical and actual payment settings

a semi nonparametric approach to the demand for uk monetary assets we estimate an asymptotically ideal model of the demand for uk personal sector monetary assets we use data that are consistent with utility maximizing behaviour and find that uk monetary assets are generally substitutes in use the estimated elasticities of substitution during the 1980s and the early 1990s indicate that a relatively broad monetary aggregate should be used in economic studies the results also suggest that any policy based on interest or user cost elasticities of substitution between financial assets should be based on the morishima elasticities as the allen uzawa calculation can give misleading results

risky monetary aggregates for the uk and us abstract we extend the scope of monetary aggregation beyond capital certain assets that make up central bank data sets and identify groups of assets that form monetary aggregates composed of both capital certain and risky capital uncertain assets we construct monetary aggregates for the us and uk using a superlative index and relax a key assumption of the consumption capital asset pricing model ccapm a one year planning horizon by using forecasted returns on risky assets our new risky monetary aggregates perform well in var tests we recommended exploring risky assets as providers of liquidity services in future research on this topic

gasoline prices fuel economy and the energy paradox abstract policymakers often assert that consumers undervalue future gasoline costs when they buy automobiles we test this by measuring whether relative prices of vehicles with different fuel economy ratings fully adjust to variation in gasoline prices vehicle prices move as if consumers are indifferent between 1 00 in discounted future gas cost and 0 76 in vehicle purchase price we show how corrections for endogenous market shares and utilization measurement error and different gasoline price forecasts affect the results we also provide unique evidence of sticky information vehicle markets respond to changes in gasoline prices with up to a six month delay

best nonparametric bounds on demand responses this paper uses revealed preference inequalities to provide the tightest possible best nonparametric bounds on predicted consumer responses to price changes using consumer level data over a finite set of relative price changes these responses are allowed to vary nonparametrically across the income distribution this is achieved by combining the theory of revealed preference with the semiparametric estimation of consumer expansion paths engel curves we label these expansion path based bounds on demand responses as e bounds deviations from revealed preference restrictions are measured by preference perturbations which are shown to usefully characterize taste change and to provide a stochastic environment within which violations of revealed preference inequalities can be assessed

the effect of uncertainty on investment evidence from texas oil drilling this paper estimates the response of investment to changes in uncertainty using data on oil drilling in texas and the expected volatility of the future price of oil using a dynamic model of firms investment problem i find that i the response of drilling activity to changes in price volatility has a magnitude consistent with the optimal response prescribed by theory ii the cost of failing to respond to volatility shocks is economically significant and iii implied volatility data derived from futures options prices yields a better fit to firms investment behavior than backward looking volatility measures such as garch jel c58 d92 g13 g31 l71 q31 the real options literature beginning with marschak 1949 and arrow 1968 and developed in bernanke 1983 pindyck 1991 and dixit and pindyck 1994 explains how firms should make decisions about investments that involve sunk costs real options theory views such investments as options in that at any point in time a firm may choose to either invest immediately or delay and observe the evolution of the investment s payoff a key insight is that the option to delay has value when future states of the world with positive returns to investing and states with negative returns are both possible even holding the expected future return constant at its present level thus in the presence of irreversibility and uncertainty a naive investment timing rule proceed with an investment if its expected benefit even slightly exceeds its cost is suboptimal because it does not account for the value of continuing to hold the option instead firms should delay irreversible investments until a significant gap develops between the investments expected benefits and costs moreover as uncertainty increases real options theory tells us that the incentive to delay should grow stronger and the gap between the expected benefit and cost necessary to trigger investment should widen while real options theory therefore prescribes how firms should carry out irreversible investments in uncertain environments it is not empirically well known

normality of demand in a two goods setting we study the testable implications of normal demand in a two goods setting for a finite dataset on prices and quantities we present the revealed preference conditions for normality of one or both goods our characterization provides an intuitive extension of the well known weak axiom of revealed preference and is easy to use in practice we illustrate the empirical relevance of our theoretical results through an application to the experimental dataset presented in andreoni and miller 2002

non parametric tests of consumer behaviour the neoclassical model of consumer behaviour postulates that a consumer s choice behaviour can be described as deriving from utility maximization subject to a budget constraint one is then naturally led to ask what this model implies about observed behaviour this question has been addressed from two quite distinct approaches the first approach originating in the work of slutsky 1915 and antonelli 1886 derives necessary and sufficient conditions involving the derivatives of the demand functions the second approach originating in the work of samuelson 1938 1947 1948 derives algebraic conditions on the demand functions implied by maximizing behaviour

gasoline prices and the used automobile market a rational expectations asset price approach this paper examines the impact of changes in gasoline price expectations on the market values of used automobiles an asset model of automobile valuation is used to relate year to year changes in market values to changes in the present discounted value of gasoline expenses econometric evidence from data covering the years 1972 through 1981 substantially confirms the hypothesis of the model that a gasoline price shock causes relative price changes across automobile types in proportion to the differences in their rates of fuel consumption

bounding an economic monetary aggregate under nonhomothetic preferences we construct nonparametric bounds on true quantity indexes for the realistic case of nonhomothetic preferences these bounds do not require assumptions about the form of the underlying aggregator function we construct these bounds using monetary assets that meet necessary conditions for the existence of an aggregate we find that a tornqvist index of these monetary assets falls within the nonparametric bounds on true quantity indexes almost all of the time whereas a simple sum of these monetary assets falls outside these bounds more than one third of the time

changing tastes and effective consistency in a single commodity setting with changing tastes an individual s consumption plan can be obtained using naive or sophisticated choice we provide two sufficient conditions for when the solutions are unique and agree and the common plan is representable by a non changing tastes utility because the solution is not revised over time the plan and associated preferences are referred to as being effectively consistent afriat style revealed preference tests are derived the assumption of effective consistency can mitigate the problems of vulnerability to dutch books non existence of a competitive equilibrium and the aggregation of heterogeneous agents with changing tastes abstract from author

directional forecasts of gdp and inflation a joint evaluation with an application to federal reserve predictions many studies have undertaken separate analyses of the fed s forecasts of real gross domestic product gdp growth and inflation this article presents a method for jointly evaluating the direction of change predictions of these variables we conclude that some of the inflation forecasts examined separately were not valuable however the joint pattern of gdp and inflation projections was generally in accord with the economy s movements directional forecasting is now an increasingly popular metric for forecasting performance pesaran and timmermann 2004 414

testing data for consistency with revealed preference the author develops a method of hypothesis testing for revealed preference tests this method is particularly well suited to tests of commonality of tastes or tests of preference stability he devises a metric based on an estimate of the fraction of expenditure wasted in maximizing utility if all consumers in the sample share the same utility function this metric increases in size with increases in the proportion of observations having different tastes and with increasing differences in tastes the author proposes bootstrap methods for estimating the distribution of the test statistic copyright 1995 by mit press

on the formation of expected inflation under various conditions some survey evidence based on the notion of economically rational expectations the author hypothesizes that the degree of the rationality of economic agents inflationary expectations differs depending on the prevailing rate and volatility of inflation this is tested for the institute for social research monthly survey data by using the inflation forecasts from an autoregressive integrated moving average model and those from a vector autoregressive model respectively as benchmarks for the weak and stronger measures of rationality the author s analysis for 1978 01 1985 06 reveals evidence in favor of the above hypothesis copyright 1992 by university of chicago press

a non parametric analysis of personal sector decisions on consumption liquid assets and leisure this paper uses the non parametric techniques developed by varian i982 i983 and afriat i967 1973 from the theory of revealed preference see samuelson 1947 to address a number of questions of interest to those who model the determination of consumption liquid assets and leisure hours 1 the primary assumption underlying much work in this area whether it deals with highly aggregated categories such as the consumption of non durables or relatively disaggregated categories such as the consumption of energy products or food is that demand functions for consumer goods are consistent with the hypothesis that they are derived from the maximisation of a well behaved utility function subject to a relevant budget constraint the absence of liquid assets or leisure from such studies involves the implicit assumption of weak separability between consumption goods and these other goods the parametric approach then assumes a particular functional form for either the utility function indirect utility function or cost function and estimates the parameters that best describe the data however as varian i983 points out when it comes to testing hypotheses in such a framework it is always a joint hypothesis comprising both the restrictions and the choice of functional form which is being tested 2 to avoid this problem varian developed the nonparametric revealed preference approach to provide algebraic conditions which are imposed by maximising behaviour on a set of data with a finite number of observations this non parametric approach is exploited here in several ways there have been a number of studies using a parametric approach at a fairly disaggregated level to the determinants of consumers expenditure see for example deaton i974 anderson and blundell i982 and ray i984 for applications using

how revealing is revealed preference this lecture address the following two key criticisms of the empirical application of revealed preference theory when the rp conditions do not reject they do not provide precise predictions and when they do reject they do not help characterize the nature of irrationality or the degree direction of changing tastes recent developments in the application of rp theory are shown to have rendered these criticisms unfounded a powerful test of rationality is available that also provides a natural characterization of changing tastes tight bounds on demand responses and on the welfare costs of relative price and tax changes are also available and are shown to work well in practice

admissible monetary aggregates for the euro area we use the fleissig and whitney fleissig a r whitney g a 2003 a new pc based test for varian s weak separability conditions journal of business and economics statistics 21 1 133 144 weak separability test to determine admissible levels of monetary aggregation for the euro area we find that the euro area monetary assets in m2 and m3 are weakly separable and construct admissible divisia monetary aggregates for these assets we show that real growth of the admissible divisia aggregates enters the euro area is curve positively and significantly for the period from 1980 to 2005 out of sample we show that divisia m2 and m3 appear to contain useful information for forecasting euro area inflation

the effects of the corporate average fuel efficiency standards in the us this paper examines the effects of the corporate average fuel economy standards cafe on automobile sales prices and fuel consumption first a discrete choice model of automobile demand and a continuous model of vehicle utilization are estimated using micro data from the consumer expenditure survey for 1984 1990 next the demand side model is combined with a model of oligopoly and product differentiation on the supply side with these elements in place the effects of the cafe regulation are assessed through simulations and compared to the effects of alternative policy instruments such as an increase in gasoline tax

the optimal level of monetary aggregation in this paper i have three objectives 1 to describe the aggregation theoretic procedure for selecting the optimal monetary aggregates 2 to survey the available empirical evidence for information on the optimal aggregates and 3 to describe the procedures that should be followed to complete a redefinition of the monetary aggregates although all of the federal reserve board s current official aggregates are rejected as targets some newer aggregates are found to be substantially preferable to the official aggregates the board s staff recently completed the official redefinition of its monetary aggregates in a manner largely unrelated to aggregation and index number theory my own research in recent years has sought to remedy that shortcoming except for monetary aggregates most of the data provided by governmental agencies are constructed in accordance with aggregation and index number theory since aggregation theory can be applied to monetary aggregation 1 i constructed new monetary aggregates that are consistent with the economic theory 2 recently the empiri

choice inconsistencies among the elderly evidence from plan choice in the medicare part d program comment consumers enrollment decisions in medicare part d can be explained by abaluck and gruber s 2011 model of utility maximization with psychological biases or by a neoclassical version of their model that precludes such biases we evaluate these competing hypotheses by applying nonparametric tests of utility maximization and model validation tests to administrative data we find that 79 percent of enrollment decisions from 2006 to 2010 satisfied basic axioms of consumer theory under the assumption of full information the validation tests provide evidence against widespread psychological biases in particular we find that precluding psychological biases improves the structural model s out of sample predictions for consumer behavior

do the asean countries and taiwan form a common currency area abstract common currency areas and asian common currency areas in particular are highly topical and somewhat controversial areas for research we explore the hypothesis that the members of the association of southeast asian nations meet necessary conditions for forming a common currency area and whether taiwan appears a natural member of such an area we test data on the asean countries and taiwan for consistency with a common currency area we produce the first evidence that these five asean countries and the asean countries plus taiwan meet the microeconomic criteria to form a common currency area

principles of analysis of internal structures of aggregate demands demand estimation problem arises each time when there is need for forecasting of the sales volume optimal price settlement for profit maximization or for empirical studies of the market for demand because there is a relationship between price and quantity demanded it is important to understand the impact of pricing on sales by estimating the demand curve for the product the current paper introduces new method of analysis of demand internal structure and compound nature depended on the contribution of various groups of customers direct and inverse problem of estimation of elementary and aggregate demands parameters are defined aggregate demand structure is represented as a multidimensional dummy variables regression model the theoretical results are verified by means of corresponding numerical example

are patient regarding preferences stable evidence from a laboratory experiment with physicians and medical students from different countries abstract we quantify patient regarding preferences by fitting a bounded rationality model to data from an incentivized laboratory experiment where chinese medical doctors german medical students and chinese medical students decide under different payment schemes we find a remarkable stability in patient regarding preferences when comparing subject pools and we cannot reject the hypothesis of equal patient regarding preferences in the three groups the results suggest that a health economic experiment can provide knowledge that reach beyond the student subject pool and that the preferences of decision makers in one cultural context can be of relevance in a very different cultural context

forecasting gasoline prices using consumer surveys this paper analyzes the predictive power of a new data set of consumer gasoline price forecasts taken from the michigan survey of consumers msc msc data generally perform as well as a no change forecast in predicting future gasoline prices and they substantially out perform the no change forecast during the recent economic crisis during which time they track futures market prices finally the cross respondent dispersion of the msc forecasts increases substantially during the economic crisis paralleling the large increase in price volatility at this time

on nonparametric demand analysis abstract building on the work of afriat and varian a nonparametric analysis of consumption behavior is presented inner bound and outer bound representations of preferences are obtained that are consistent with both the data and consumer theory it is shown how a priori information on demand response can be incorporated in the analysis the approach generates estimates of price and income elasticities of demand an application to u s consumption data illustrates the usefulness of the method for predicting demand behavior as well as for welfare analysis

homothetic efficiency theory and applications we provide a nonparametric revealed preference approach to demand analysis based on homothetic efficiency homotheticity is widely assumed often implicitly because it is a convenient and often useful restriction however this assumption is rarely tested and data rarely satisfy testable conditions to overcome this we provide a way to estimate homothetic efficiency of consumption choices the method provides considerably higher discriminatory power against random behavior than the commonly used afriat efficiency we use experimental and household survey data to illustrate how our approach is useful for different empirical applications and can provide greater predictive success

divisia aggregation and substitutability among monetary assets in this paper the authors estimate the degree of substitutability among the services of money checkable deposits savings deposits and time deposits in a quasi homothetic translog utility framework for canada the four composites mentioned are formed by aggregating more basic assets such as checkable deposits at banks checkable deposits at trust companies etc traditionally the simple sum aggregation has been used in this context the authors investigate both this alternative and divisia aggregation of the assets they find a low degree of substitution among the services of monetary assets and provide some evidence favoring divisia aggregation over simple sum aggregation copyright 1986 by ohio state university press

nonparametric tests of utility maximization and weak separability for consumption leisure and money some of the most fundamental assumptions of economics are utility maximization and weak separability of the arguments in the represen tative consumer s utility function this paper contains results from nonparametric tests of these assumptions about consumer behavior the authors find that quarterly per capita data on consumption goods le isure and monetary assets are consistent with utility maximization further consumption goods and leisure meet necessary and sufficient conditions for weak separability additionally one grouping of relat ively liquid monetary assets meets the necessary conditions for weak separability they also test and find no evidence of homothetic prefe rences copyright 1987 by mit press

institutional barriers to policy reform in egypt the case of the agricultural machinery industry abstract economic reform has been on the egyptian policy agenda since the mid 1970s but progress has been slow in part due to strong regulatory and institutional obstacles the experience of the agricultural machinery manufacturing industry displays this problem an economic analysis of manufacturing threshers shows that while the impact of price policies was about neutral institutional barriers effectively taxed the industry 15 22 the greatest obstacle was access to marketing credit from the state owned principal bank for development and agricultural credit access to materials and difficulties with tax authorities also hampered the industry

the translog utility function and the demand for money in the united states in recent years considerable effort has been directed towards establishing the nature of the relationship between money and nearmonies but with mixed success the approaches vary from multi interest rate single equation studies to the careful simultaneous equations studies summarized and amended by feige and pearce 1977 and extended recently by donovan 1978 offenbacher 1979 and barnett 1980 the empirical results also vary with numerous studies favoring only one interest rate see the surveys in fisher 1978 1983 some claiming that a variety of entities are close substitutes for money e g chetty 1969 and others showing that weak substitution or even complementarity may be the result of the measurement of elasticities of substitution between money and a number of other assets e g feige and pearce 1977 offenbacher 1979 and barnett 1980 the debate seems to have overshadowed a second and equally intriguing issue which centers on the establishment of an acceptable definition of money the basic idea of this study is to take an approach that takes account of the different degrees of moneyness possessed by the various monetary assets this paper produces quantitative estimates of the degree of substitutability of other monetary assets for money in the context of a flexible functional form model with a

impact of satisficing behavior in online surveys on consumer preference and welfare estimates conducting online surveys through consumer panels has become increasingly popular for researchers to assess consumers preferences and attitudes for the purpose of obtaining welfare estimates because they are inexpensive flexible and allow for fast feedback interestingly few studies have examined the behaviors of online survey panelists particularly their satisficing behaviors on welfare measures this study demonstrates the use of validation questions trap questions to detect survey respondents satisficing behavior and its impact on consumer choice willingness to pay wtp and consumer surplus cs estimates we find that respondents who fail a validation question vq are more likely to violate the weak axiom of revealed preferences warp in the choice experiment the estimates for preference parameters wtp and cs are statistically different between those who pass and those who fail the vq in addition the wtp and cs from respondents passing the vq in general have smaller variances than those from respondents failing the vq these results indicate that without controlling for potential satisficing behaviors online surveys may produce less efficient estimates estimates with larger variance of welfare measures

predicting gasoline prices using michigan survey data abstract this study investigates the predictive power of michigan surveys of consumers msc data for gasoline prices specifically we utilize the msc data on both expected inflation and consumer sentiment to construct a vector autoregressive var model for forecasting gasoline prices for 2003 2014 our findings indicate that the var forecasts are superior to the comparable benchmark forecasts obtained from a univariate integrated moving average ma model in terms of both predictive information content and directional accuracy as such we conclude that the msc data on both expected inflation and consumer sentiment have significant predictive information for gasoline prices further inspection reveals that the var forecasts are particularly accurate for the period since 2008 reinforcing the notion that consumers are economically rational
