is the stock market sticker shocked a study of market response to recent cafe regulations in the us in response to increasing environmental concerns to improve energy security and to conserve energy use the us government has proposed a new round of corporate average fuel economy cafe standards many studies have focused on how the cafe standard can be met by various automakers that have sales in the us market and the costs and benefits of the companies meeting the standard however the stock markets view on the impact of the standard on automakers profitability is largely absent we study the more recent episode of the cafe regulation in an effort to try to detect the market response using the standard event study method our empirical findings suggest that while the stock market had some responses to the regulation the large scale and systematic reaction to the regulation is absent in addition the market response pattern to the regulation appears to be tied to the individual company s compliance condition if there is any significant response at all

growth rates with an exhaustible resource and home goods abstract the growth path of an exhaustible resource exporting economy is examined previous work has shown that the size of the non resource sector of such an economy may shrink to zero over time this paper shows that this result hinges on the exclusion of the non traded sector of the economy with both traded and non traded sectors included the domestic interest rate may fluctuate more widely than the world interest rate despite the results of previous work finally the paper questions a dutch disease literature result even when the industrial sector is more resource intensive than the service sector it is possible for a faster growing resource price to have a pro industrialization effect

offsetting behavior effects of the corporate average fuel economy standards john m yun 1 introduction consumers value many attributes of an automobile the problem for regulators is that many features are highly interrelated such as safety and fuel economy improvements both features are highly correlated with vehicle weight greater weight increases the level of safety in terms of crashworthiness but decreases the fuel economy therefore regulatory attempts to improve fuel economy such as the corporate average fuel economy cafe standards 1 are likely to alter average vehicle weight which will alter the safety of a vehicle crandall and graham 1989 find the reduction in weight attributable to cafe results in a 14 28 increase in occupant fatality risk this article seeks to determine whether drivers are changing their behavior to mitigate the detrimental safety effects of cafe which is essentially another application of peltzman s 1975 offsetting behavior hypothesis cafe through a reduction in passenger car weight will increase the ex ante cost of risky driving 2 relative to its expected benefit the reason is that once an accident occurs the probability of serious injury or death has increased the offsetting behavior hypothesis is that consumers aware of the increased vulnerability will exercise greater due care and reduce the amount of risky driving on the road as a result of cafe however cafe has not just affected the average passenger car weight godek 1997 and yun 1999 indicate that cafe has positively affected the relative sales of light trucks 3 to passenger cars if we assume that light trucks are basically heavy cars with greater visibility the same arguments made for offsetting behavior on the part of passenger car drivers can be applied here 4 the main difference is that truck drivers will be more aggressive and risky because trucks are heavier which lowers the cost of risky driving thus if cafe induces more trucks to be on the road according to the offsetting behavior hypothesis cafe will increase the amount of aggressive truck driving while simultaneously decreasing the amount of aggressive car driving although the article will focus on the offsetting behavior from changes in passenger car weight it is just as relevant for changes in relative truck miles driven section ii reviews the recent research linking automobile weight changes with cafe and recent empirical studies that apply offsetting behavior to automobile regulations 5 section iii details the methodology used to test the offsetting behavior hypothesis section iv contains a discussion of the data the results are reported in section v and section vi concludes the article ii background the cafe standards were initially set at 18 0 mpg for passenger cars and between 15 8 to 17 2 mpg for various light trucks these standards have steadily increased to the current levels of 27 5 mpg for passenger cars and 20 7 mpg for light trucks 6 the key impact of cafe on consumer safety is a reduction in the average passenger car weight figure 1 illustrates the fall in weight since cafe s passage in 1975 crandall and graham 1989 attribute 14 of the fall in weight to cafe 7 using single car accident data they estimate the elasticity of highway occupant fatality rates with respect to average car weight is between 1 22 and 2 30 which implies a 17 32 2 increase in the fatality rate due to cafe using the upper and lower bounds crandall and graham 1989 estimate that cafe is responsible for 2 200 3 900 more deaths over the life span of the cars from a given model year 8 however there is no attempt to explicitly measure possible offsetting behavior effects not all studies find a positive relationship between weight and safety the general accounting office gao 1991 acknowledges a theoretical link between automobile size and safety however they find no direct empirical link between the two

real and nominal factors in the cyclical behavior of interest rates output and money abstract short term nominal interest rates output unemployment monetary growth and inflation are represented as functions of two common latent indices a real index that underlies co movements in output and unemployment and a neutral index that is independent of output a fisherian interpretation of the real and neutral components of interest rates is provided under the assumption that anticipated inflation affects output primarily through its effect on real interest rates then monthly time series on the real and neutral components of short term treasury bill yields are constructed and the cyclical behavior of these series is compared to the behavior of output and monetary growth

car buyers and fuel economy abstract this research is designed to help researchers and policy makers ground their work in the reality of how us consumers are thinking and behaving with respect to automotive fuel economy our data are from semi structured interviews with 57 households across nine lifestyle sectors we found no household that analyzed their fuel costs in a systematic way in their automobile or gasoline purchases almost none of these households track gasoline costs over time or consider them explicitly in household budgets these households may know the cost of their last tank of gasoline and the unit price of gasoline on that day but this accurate information is rapidly forgotten and replaced by typical information one effect of this lack of knowledge and information is that when consumers buy a vehicle they do not have the basic building blocks of knowledge assumed by the model of economically rational decision making and they make large errors estimating gasoline costs and savings over time moreover we find that consumer value for fuel economy is not only about private cost savings fuel economy can be a symbolic value as well for example among drivers who view resource conservation or thrift as important values to communicate consumers also assign non monetary meaning to fuel prices for example seeing rising prices as evidence of conspiracy this research suggests that consumer responses to fuel economy technology and changes in fuel prices are more complex than economic assumptions suggest the us department of energy and the energy foundation supported this research the authors are solely responsible for the content and conclusions presented

an empirical investigation into the international real interest rate linkages linear dynamic stochastic processes are derived for the ex ante real interest rates from those followed by the ex post real rates under the identifying assumption of rational expectations the technique is used to study instantaneous and lagged effects of u s ex ante real rates on a number of oecd ex ante real rates the author finds significant contemporaneous correlations between ex ante real rates in the long run however real rates seem to be insulated

on the intergenerational allocation of natural resources it is known hartwick and others that under standard assumptions a society that invests in reproducible capital the competitive rents on its current extraction of exhaustible resources will enjoy a consumption stream constant in time it is shown here that this result can be interpreted as saying that an appropriately defined stock of capital including the initial endowment of resources is being maintained intact and that consumption can be interpreted as the interest on that patrimony this seems like a useful rule of thumb for policy

forecasting inflation using interest rate and time series models some international evidence it has been suggested that inflation forecasts derived from short term interest rates are as accurate as time series forecasts previous analyses of this notion have focused on u s data providing mixed results in this article the authors extend previous work by testing the hypothesis using data taken from the united states and five other countries using monthly eurocurrency rates and the consumer price index for the period 1967 86 their results indicate that time series forecasts of inflation have equal or lower forecast errors and have unbiased predictions more often than the interest rate based forecasts copyright 1990 by the university of chicago

climate policy under factor mobility a differentiated case for capital taxation abstract in a general equilibrium model with two periods and a finite fossil resource i analyze the non cooperative climate policies of symmetric countries that are in competition for mobile factors of production capital and fossil energy the paper shows that countries that want to slow down climate change but are also concerned about tax revenues from mobile tax bases have a rationale to supplement environmental taxes on fossil fuels with source based capital taxes or subsidies more specifically countries find it beneficial to subsidize capital in period one and tax it in period two the first period subsidy on capital facilitates a higher environmental tax by counteracting its adverse effects and increases national and global welfare in equilibrium by contrast the capital tax in period two induces inter and intratemporal distortions that lead to lower welfare the rate of resource extraction is inefficiently high in equilibrium no matter which tax portfolio is at the governments disposal furthermore unintended green paradox effects of demand side policies are shown to arise even in general equilibrium with factor mobility finally factor mobility does not necessarily lead to a higher rate of extraction and lower welfare compared to autarky

the relation between stock prices and inflationary expectations the international evidence this paper provides empirical evidence on the relation between stock returns and inflationary expectations for nine countries over the period 1971 80 the fisherian assumption that real returns are independent of inflationary expectations is soundly rejected for each major stock market of the world using interest rates as a proxy for expected inflation our data provide consistent support for the geske and roll model whose basic hypothesis is that stock price movements signal negative revisions in inflationary expectations finally a weak real interest rate effect was found for some of these countries

international interest rates and inflationary expectations abstract fama s hypothesis that short term interest rates are efficient predictors of inflation has been criticized on the grounds that his test depends critically on the constancy of the short term expected real rate of interest this paper uses an international framework where the time invariance assumption of the real rate is replaced by the assumption that short term expected real rates are identical at a point in time across countries with well developed capital markets results support fama s contention that short term nominal rates of interest reflect inflationary expectations

on the constancy of real interest rates and the mundell effect in reply to fama s 1975 tests on market efficiency and the constancy of the ex ante real rate nelson and schwert 1977 have demonstrated that the tests were not sufficiently powerful we have shown that all the structural parameters of their model are identifiable as such the random forecasting errors do not confound the problem of identifying variations in the real rate we estimated the mundell effect and demonstrated that in terms of in sample predictive efficiency the simple fisherian framework to generate real rates fairs quite well once rationality is imposed

on the accuracy of time series interest rate and survey forecasts of inflation there has been much work examining and evaluating different methodologies in forecasting inflation for example fama 1975 1977 develops an interest rate model to predict the 1 monthahead rate of inflation using the cpi fama and gibbons 1982 1984 modify the interest rate model to account for a nonconstant real rate of interest and compare it to a univariate timeseries forecasting model and to the livingston forecasts carlson 1977a 1977b and others also analyze the consensus forecasts from the livingston survey pertaining to multiperiod forecasts of inflation pearce 1979 considered the livingston survey and time series forecasts our purpose in this paper is to investigate further the relative forecasting ability of three different methodologies in contrast to previous studies that have generally used the cpi to measure inflation our analysis uses the implicit gnp deflator this modification is motivated largely by the fact that calculations of the cpi inflat n rate often are distorted greatly by changes in relative prices e g blinder 1980 fischer 1981 this paper compares the accuracy of three different inflation forecasting procedures these include a univariate time series model an interest rate model based on the methodology of fama and gibbons and the median forecasts derived from the american statistical association national bureau of economic research survey the evidence presented is based on ex ante forecasts of quarterly inflation rates using the gnp deflator for the period 1970 11984 11 based on the evidence presented the general conclusion is that the survey forecasts provide the most accurate inflation forecasts

booming sector and de industrialisation in a small open economy this paper presents a theoretical analysis of the dutch disease the phenomenon whereby a boom in one traded goods sector squeezes porfitability in other traded goods sectors both by directly bi

the sources of the movements in interest rates the paper investigates the sources of interest rate movements in italy during the 1970s in that decade the country experienced the highest and most variable inflation rate among the industrial nations and was affected both by external shocks and by shocks to the labor and financial markets the paper shows that movements in inflationary expectations dominated the nominal interest rate variability the part of variability that was not explained by expected inflation was accounted for by unanticipated changes in the terms of trade by contrast domestic monetary and real disturbances did not have a sizeable impact on the variability

a model of uk real effective exchange rate behaviour an integrated model of the uk real effective exchange rate is examined which links purchasing power parity with trade flow and asset market mechanisms furthermore time series and econometric analysis using quarterly data from 1972 to 1987 are applied the results obtained are broadly consistent with this model and imply that the uk real effective exchange rate index is constant in the long run

the fisher effect in a signal extraction framework the recent brazilian experience abstract this paper derives a signal extraction framework for examining all testable implications of the fisher equation the signal is the net of taxes nominal interest rate which under the fisher model equals inflation expectation plus the real rate assumed to be constant or a constant plus a martingale difference all alternative linear models can be represented as noise added to the signal the international and brazilian literature are briefly reviewed and the empirical tests reinterpreted in the signal extraction framework the model is tested with brazilian data for the period 1973 1990 using interest rate data on non indexed certificates of deposit from a sample of major brazilian banks the framework detects little noise i e the fisher equation seems to reasonably fit the brazilian evidence this result carries the policy implication that the government cannot have the burden of financing its fiscal deficits ameliorated by issuing non indexed debt in periods when inflation is escalating given the large fluctuations observed in ex post real rates in brazil the reasonable success of the fisher equation also implies the existence of large inflation forecast errors which suggest the need for further research on how agents form inflation expectations when inflation escalates rapidly as it did in the late 1980s in brazil price indices lag behind true inflation this generates a fisher effect even for indexed securities the empirical evidence also corroborates the existence of this fisher effect for indexed securities

short term interest rates as predictors of inflation comment in this note i raise two questions regarding fama s results the first is whether similar tests based on an information set somewhat broader than the past history of consumer price inflation will support fama s findings the second is whether given fama s data and model his results fully support his hypotheses the answer to both questions is no if one accepts the accuracy of the data during fama s sample period the current monthly rate of change of consumer prices ct is significantly related to the three previous monthly rates of change of

is public expenditure productive abstract this paper considers the relationship between aggregate productivity and stock and flow government spending variables the empirical results indicate that i the nonmilitary public capital stock is dramatically more important in determining productivity than is either the flow of nonmilitary or military spending ii military capital bears little relation to productivity and iii a core infrastructure of streets highways airports mass transit sewers water systems etc has most explanatory power for productivity the paper also suggests an important role for the net public capital stock in the productivity slowdown of the last fifteen years

unit roots and persistence in the nominal interest rate a confirmatory analysis applied to the oecd this paper investigates the stochastic properties of long term and short term nominal interest rates for the oecd over the post war era for that purpose we employ univariate unit root tests as well as panel unit root and stationarity tests that explicitly allow for cross sectional dependence overall we find overwhelming evidence that the nominal interest rate contains a unit root which may be driven by a stochastic common factor the computation of half lives through impulse response functions also points to a high degree of persistence this has important implications for the cointegration analysis of the fisher equation the uncovered interest parity and the term structure jel classification

estimation of the specification error in the fisher equation this paper asks how false is the fisher hypotheis previous work has asked is the fisher hypothesis true the framework here characterizes the specification error in the the fisher equation as model noise following durlauf and hall 1988 1989a 1989b the noise provides a metric for the specification error for the post war period to october 1979 the variance of the noise is small while after that date it is apparently large that is using a method that contains many previous tests of the fisher effect in explaining nominal in explaining nominal interest rate movements mishkin 1991 has criticized this consensus as reflection a common stochastic trend in inflation and nominal interest rates prior to october 1979 the test here is immune to this criticism as i use the ex post real interest rate as the regressand and show that at least prior to october 1979 it obeys a sationary process

the effect of the discount rate on depletion of exhaustible resources this paper argues that despite its widespread acceptance in the literature the basic proposition that a reduction an increase in the discount rate leads to greater conservation faster depletion of an exhaustible resource is not generally valid it shows that the effect of the discount rate on the rate of resource depletion depends on capital requirements for production of the substitute and extraction of the resource and on the size of the resource stock in fact it shows that there always exist at least two ranges of the resource stock size for which the effect is opposite to that conventionally believed

the time path of scarcity rent in the theory of exhaustible resources there is now a consensus in the literature on resource economics that a depletable resource should command a price in excess of its marginal extraction cost simply to reflect the opportunity cost of using a unit of it today rather that conserving it for the future but how this excess is to change along an optimal or competitive equilibrium path of resource use is still an unresolved question this might at first seem puzzling since according to the fundamental theorem of economics of exhaustible resources or hotelling i 93 i rule on an optimal path price minus marginal extraction cost also termed interchangeably as scarcity rent user cost or royalty should steadily grow over time at the social rate of discount however the literature contains sharply contrasting views on the subject for example kay and mirrlees 1975 have argued that since along an optimal path the scarcity rent grows exponentially as a finite stock of a resourcexnears exhaustion then situations in which the resource stock is still very large and yet the price greatly exceeds the marginal extraction cost should indicate that the price is significantly above its optimal level and that the resource is overconserved in stark contrast to this view heal i976 has argued that as the resource stock nears exhaustion the difference between price and marginal cost or what he termed social cost of extraction falls monotonically to zero hanson i980 analyses the same model as heal s but unlike heal who assumes the unit extraction cost to be convex he postulates it to be concave and yet like heal concludes that the scarcity rent will be monotonically declining over time solow and wan i976 analyse a still different situation where resource deposits differ in quality and the unit extraction cost increases as higher grade deposits are exhausted and extraction proceeds to lower grades they show that along an optimal path the shadow price of a resource must rise at the real rate of interest despite differential extraction costs but that the difference between price and the marginal extraction cost or what they call degradation charge declines monotonically over time to zero these sharply differing conclusions suggest that far from being resolved the question of how scarcity rent changes over time is much in want of a close scrutiny the need for such a scrutiny becomes even stronger once it is noted

a random walk through the gibson paradox evidence to support the gibson paradox is often given in the form of a simple correlation between the nominal interest rate and the log of price level or in the form of a simple linear regression between these two variables authors then show using standard procedures of statistical inference that the price level possesses a significant coefficient we argue that this class of evidence is spurious since the nominal interest rate and the price level both integrated variables do not form a cointegrated system

automobile quality choice under pollution control regulation in this paper we develop a modified quality choice model to study the effects of various mobile source air pollution control regulations we have a single producer that supplies a fixed number of car types two but faces a spectrum of consumers differing in their valuation of car quality the car manufacturer chooses the quality levels of the two car types as well as the sales mix between the two types and the size of the market it wishes to supply by endogenizing both the sales mix and the market size while still allowing quality to be a choice variable we are able to more completely analyze the impact of any car pollution control regulation existing studies of this impact either focus on the model line adjustment response shifts in the quality array or on the price adjustment response changes in the sales mix and market size in allowing for both the model line and the price adjustment options we find that the corporate average fuel efficiency cafe standard is unambiguously welfare superior to the low emission vehicle quantity constraint lev and zero emission vehicle zev programs we also show that the effects of the cafe standard are not equivalent to those of a fuel tax as previously found and that for a given car pollution target the former is preferred to the latter

the effects of inflation and income taxes on interest rates some new evidence this paper reexamines the empirical relation between inflation and interest rates concentrating on the tax effect proposed by darby and feldstein using the random walk intercept model relative responses of taxable yields and tax exempt yields to expected infla tion are estimated the results show that for the sample period 1953 1982 the nominal yields on treasury bills rise at a rate greater than one for one with expected inflation while the nominal yields on default free municipal bonds rise approximately one for one with expected inflation thus the tax adjusted fisher hypothesis by darby and feldstein is empirically supported the components of treasury bills are also extracted and their variances are compared it is shown that variation of expected inflation is not overwhelmingly larger than that of the after tax real rate therefore on an after tax basis changes in the real rate explain a substantial portion of changes in the nominal rate of interest

short term interest rates as predictors of inflation on testing the hypothesis that the real rate of interest is constant in an innovative and provocative paper in this review eugene fama presents evidence which appears to be consistent with the joint hypothesis that the real rate of interest ignoring taxes is a constant and that the market for u s treasury bills is efficient in the sense of embodying rational expectations those findings are strikingly at variance with a long list of previous studies which seemed to support the view that the real rate of interest varies over time and can be related to economic variables such as real output monetary policy and so forth 2 the methodologies which lead to these contradictory conclusions are quite different previous studies had followed the lead of irving fisher by relating nominal interest rates to distributed lags on past rates of inflation 3 these distributed lags are generally interpreted as approximations to the market s expected rate of inflation and thus any remaining variation is attributed to variation in the real rate 4 fama s methodology on the other hand draws on the fact that the difference between the market interest rate and the subsequently observed rate of inflation the ex post real interest rate consists by definition of the ex ante real interest rate plus a pure forecasting error 5 the hypothesis of market efficiency implies that these forecasting errors must be serially random thus observing ex post real rates is equivalent to observing ex ante real rates with random measurement error these errors of course confound the problem of identifying variation in the ex ante real rate in this paper we will argue that the relative magnitude of these measurement errors is such that the tests carried out by fama were not powerful enough to reject the joint hypothesis that the ex ante real rate is a constant and expectations are rational more powerful tests which are presented in this paper using the same data do lead to rejection of that hypothesis of course rejection

optimal saving policy for exhaustible resource economies abstract the paper examines the optimal saving policy for a small exhaustible resource exporting economy ere that has an exhaustible asset and a reproducible capital stock it shows that both in magnitude and time profile the optimal saving policy for an ere sharply differs from a that of a nonextractive economy and b that derived from the conventional models of growth with exhaustible resources these differences arise from the specific economic features that distinguish the small resource exporting developing economies both from other developing economies and from mature industrial ones for a wide range of plausible parameter values comparisons of computed optimal saving paths with actual savings rates of selected eres suggest substantial deficiencies in their savings rates
