approximating wtp and wta for environmental goods from marginal willingness to pay functions abstract willingness to pay wtp and willingness to accept wta for a change in the quantity of an environmental good can be represented by corresponding hicksian welfare measures the paper suggests a simple method of approximating wtp and wta given the information about the marginal willingness to pay mwtp for it it demonstrates that a polynomial based on the mwtp function allows to approximate the hicksian measures which may differ considerably much better than consumer s surplus in quantity space

estimation of a taiwan monetary reaction function with time varying parameters this paper employs a nonlinear kalman filter to examine the time varying responses of taiwan s monetary policy in the presence of a limited dependent variable the kalman filtered parameters reveal that the responses are not constant but change over time furthermore a counter cyclical reaction function is identified and a stronger than usual discretionary policy during the recessions is found

a review of wta wtp studies abstract willingness to accept wta is usually substantially higher than willingness to pay wtp these constructs have been studied for roughly 30 years and with a wide variety of goods this paper reviews those studies we find that the less the good is like an ordinary market good the higher is the ratio the ratio is highest for non market goods next highest for ordinary private goods and lowest for experiments involving forms of money a generalization of this pattern holds even when we account for differences in survey design ordinary goods have lower ratios than non ordinary ones we also find that ratios in real experiments are not significantly different from hypothetical experiments and that incentive compatible elicitation yields higher ratios

efficient methods of measuring welfare change and compensated income in terms of ordinary demand functions a utility maximizing consumer with a completely known system of ordinary demand functions q h p c is considered let p qo and p q be two arbitrary equilibrium situations the problem is to evaluate in which of the situations the utility is higher without knowing the utility function revealed preference theory tells that the ordinary demand functions which are in principle observable contain enough information to solve the problem remaining difficulties are therefore mainly computational we present how the compensated income c i c p qo and the compensated demand h p cl1 are calculated with arbitrary accuracy using only the ordinary demand system our two efficient algorithms also have interesting interpretations in terms of index numbers and consumer surplus measures

adaptive versus rational expectations and the fisher effect substantial controversy remains over the causes of interest rate fluctuations this controversy frequently focuses on the role of expected inflation the theoretical determinats of the nominal rate are examined usig the is lm as model and it is shown that the augmented fisher equation is sensitive to the expectations generating mechanism the model assumes that the nominal rate ceteris paribuschanges one for one with expected inflation the total impact however may take any value from zero to one the empirical analysis sequentially estimates reduced form equations based on adaptive and rational expectations the results confirm prior findings that nominal rates do not adjust one for one with inflation the results also yield some insight on the applicability of the assumption of rational versus adaptive expectations

money supply announcements and interest rates another view in this paper i use a new approach to analyze the impact of money supply announcements on the bond market before 1980 the only available work on this subject consisted of a few unpublished papers by conrad 1978 sivesind 1978 and urich 1979 1 more recently published papers by grossman 1981 and urich and wachtel 1981 have appeared roley 1982 extends the grossman study to incorporate data after the federal reserve policy statement of october 6 1979 both grossman and urich and wachtel are primarily concerned with the question of money market efficiency using survey data made available by money market services of san francisco and data on treasury bill yields each finds that the market responds quickly to unanticipated changes in the money supply but that anticipated changes have no effect on interest rates in addition grossman finds that when he adds other variables such as past changes in the money

the identification of monetary policy disturbances explaining the liquidity puzzle abstract this paper examines recent work on the identification of monetary policy disturbances its main finding is that the empirical anomalies found in the literature reflect a failure to properly address the federal reserve s policy of accommodating reserve demand shocks a new method of identifying monetary policy using nonborrowed reserves is proposed using this specification policy has a strong persistent liquidity effect regardless of subsample policy granger causes output even in the presence of interest rates explaining approximately 49 of the variance in output at a two year horizon and the residual explanatory power of interest rates for output is negligible

exogenous tax changes and interest rates testing for ricardian equivalence using an efficient markets model this article tests the ricardian theory i e barro 1974 using mishkin s 1981 1982 efficient markets model of interest rates employing romer and romer s 2010 measure exogenous tax changes i am able to test whether the u s bond market reacts in a keynesian or ricardian manner to exogenous tax policy changes this helps avoid the endogeneity problems associated with measuring the interest rate effects of deficits and provides a cleaner test of the pure ricardian thought experiment i find a significant negative relationship between tax changes and interest rates which is inconsistent with the ricardian model and support the keynesian crowding out framework

optimal production with learning by doing abstract this paper characterizes optimal production over time when production cost is a decreasing function of past accumulated output when production exhibits learning by doing monopolistic competitive and socially optimal solutions are considered

the fragmentation of the bargaining society wage setting in the nordic countries 1950 to 1992 it is commonly believed that corporatist bargaining institutions have been in general decline in the 1980s and 1990s the leading explanations of the purported universal trend toward greater decentralization of collective bargaining are the impact of technological change changes in the occupational structure and growing international economic integration decentralization should be particularly visible in the nordic countries because collective bargaining was more centralized in these countries in the 1960s and 1970s than in any others in western europe in this article the authors present data on the changes in the centralization of wage bargaining in the four nordic countries since 1950 they document that a significant decentralization of collective bargaining has occurred in sweden as is well known but not in the other three the article concludes with a review of possible explanations of swedish exceptionalism

does the federal reserve affect asset prices abstract the federal reserve is probably one of the institutions most closely monitored by investors this indicates that investors believe the actions of the fed have implications for asset prices to this date the trading activities of the fed in the financial markets have not been examined to see how the fed influences asset prices using daily data on open market operations omos and asset prices this study fills this void one finding of the paper is that omos granger cause both short and long term interest rates furthermore the sign of the relationship confirms the existence of the liquidity effect given that its trades represent a small portion of the market volume how the fed influences bond prices is a puzzle the only reasonable explanation is that the fed s trades have high information content judging by the impulse response paths the reaction of interest rates to open market operations is fast additionally it appears that monetary policy has a lasting impact on interest rates

divergence in alternative hicksian welfare measures the case of revealed preference for public amenities this paper investigates the divergence between the two hicksian welfare measures of non traded amenity improvement associated with housing first the hicksian surplus measures for amenity changes are analytically developed based on explicit specification of utility structures a hedonic two stage approach is then applied to empirically show that for quantity changes in contrast to hypothetical markets divergence in real market is small the paper also analytically develops expressions for the income and substitution effects and empirically shows that for a given income effect the greater the substitution effect the smaller the divergence between the two measures copyright 2002 john wiley sons ltd

daily monetary impulses and security prices this paper uses swiss data to study the real long run effects of monetary policy daily unexpected changes in the monetary base are found to be negatively correlated with security price changes this result is unaffected when implicitly following geske and roll 1983 we try to measure the autonomous component of monetary policy by taking into account a reaction function of monetary policy to changes in real variables

market socialism the current debate with the decline of command economies in eastern europe china and elsewhere the systemic issue of the feasability of combining the market mechanism with some form of public or collective ownership or control over the distribution of surplus has assumed topical importance the essays in this book aim at advancing the old debate on this issue to a new analytical stage questions of incentive compatability agency problems depoliticization of economic decisions and those of justice and worker autonomy are at the heart of the discussion the defenders as well as critics of market socialist proposals in this book are particularly sensitive to the centrality of these questions

measuring welfare changes in settings with imposed quantities abstract an intuitively attractive money metric utility measure is developed which is applicable in settings where individuals receive fixed quantities of one or more goods one use of this measure is in cost benefit analyses of imposed quantity changes the approximate measures typically used are shown to be subject to relatively large approximation errors however techniques are presented which can always be used to numerically evaluate the exact welfare measure provided that one knows the uncompensated demand function s or marginal willingness to pay function s of individuals

consumer s surplus versus compensating variation revisited consumer s surplus and a second order approximation to compensating variation are compared to the exact compensating variation for a subsystem of several commodities an empirical application to the relative retail price distortions created by the u s dairy program is presented in the application a new specification for weakly integrable incomplete demand models is developed and estimated the integrable demand model has sufficient flexibility that it is not rejected by the data both welfare approximations are found to introduce large errors in the measurement of deadweight losses

evaluation of nonmarket goods recovering unconditional preferences a new approach is proposed for the evaluation of nonmarket goods starting from a complete or incomplete conditional demand system for market goods which is observable and depends on nonmarket goods this information is not sufficient to recover the underlying preference ordering of the representative consumer the central idea is to employ additional marginal willingness to pay functions for the nonmarket goods since they can be estimated either together with the demand system or in a separate step they are less arbitrary than the assumptions or hypotheses usually made if the entire system is weakly integrable the underlying ordering and appropriate welfare measures can be derived in this article i investigate the relationship between conditional and unconditional demand systems present sufficient conditions for weak integrability and demonstrate the practicability of the procedure proposed by means of three examples

revealed preference and household production abstract the paper deals with the possibilities of recovering the underlying preference ordering from observed behavior when nonmarket goods are employed in household production the problem is relevant for the evaluation of environmental goods and for the measurement of welfare in environmental policy it is shown that preferences can be recovered if and only if a corresponding mixed demand system can be integrated this system can be derived from observable behavior and the household production functions imposed the conditions for its integrability are presented and can be checked therefore the approach suggested is operational and allows to decide whether the behavior observed and the household production functions chosen as maintained hypothesis are consistent this result is important since the evaluation of nonmarket goods in this framework crucially depends on the choice of the household production functions

labour market institutions and economic performance labour markets richard freeman do particular types of labour market institution hold the key to economic success should other countries try to emulate the flexibility of the american labour market or the centralization of swedish style corporatism since 1970 within the oecd there has been a sharp divergence both of economic performance and of indicators of labour market structure the paper uses union density and the degree of wage dispersion across industries to proxy a country s underlying labour market institutions in assessing economic performance it is argued that cross country differences in output growth were much smaller than differences in employment growth for given output growth there is a clear negative relationship between employment growth and real wage growth across countries why do different countries find themselves at different points on this trade off the final part of the paper examines the correlation between indicators of labour market structure and the position on the wage employment trade off it concludes that the degree of wage dispersion across industries is the most important indicator of market structure and that countries with very high or very low dispersion typically the countries with highly centralized or highly decentralized bargaining in the labour market have better employment performance than countries with intermediate degrees of centralization and wage dispersion

public and private returns from joint venture research an example from agriculture public research institutions are turning increasingly to the private sector for additional financial support such a trend in the short run lessens the need for public research expenditures but may in the long run prove to be very costly to the economy as a whole this is because private funding increases the chance that the direction of research will shift so that private benefits are enhanced such a shift is especially costly if public research funds are then not forthcoming that would have the potential of producing the maximum level of benefits to the economy as a whole a case study of canadian barley research is used to illustrate this problem

surplus maximization and optimality i identify assumptions under which policies that maximize expected surplus are pareto optimal even when expected consumer surplus does not even locally represent preferences over price income lotteries besides the oft made partial equilibrium assumptions that only one price varies and that income changes do not aect demand the two other assumptions are that every consumer s indirect utility function is supermodular in price and income and policies order prices by a single crossing property supermodularity holds precisely if relative risk aversion exceeds the income elasticity of demand a mild condition the single crossing property appears strong but holds in many applications that use expected surplus

health insurance tradeoffs revisited abstract in two recent papers journal of health economics 18 2 141 152 journal of health economics 18 6 811 824 nyman raised some questions about the welfare calculations and conclusions in our earlier paper manning and marquis health insurance the tradeoff between risk pooling and moral hazard vol 15 1996 this note discusses the erroneous criticisms in his papers first although we estimated a marshallian demand curve our calculations are based on compensating variations that incorporate the gains from risk pooling second our estimates of second best insurance plans indicate that some cost sharing is optimal in contradiction to his assertion that our results raise questions about the desirability of insurance coverage the comment also deals with other issues raised by nyman

monetary policy and long term interest rates an efficient markets approach abstract this paper is an application of efficient markets theory to analyze empirically the relationship of money supply growth and long term interest rates this approach has the advantage over calier research on this subject in that it imposes a theoretical structure on this relationship that flows easier interpretation of the empirical results as well as more powerful statistical tests on the interest of ascertaining the robustness of the results many different empirical tests are carried out in this paper and they uniformly do not support the preposition that increases in the money supply are correlated with declines in long rates

the economic benefits of surface water quality improvements in developing countries a case study of davao philippines two nonmarket valuation techniques the contingent valuation method and travel cost model are used to estimate the economic value that people in davao philippines place on improving the water quality of the rivers and sea near their community the contingent valuation and travel cost estimates are very close to each other and are quite low both in absolute terms and as a percentage of household income these findings suggest that water pollution control is simply not a high priority for davao s residents and support the argument that households willingness to pay for environmental amenities such as improved water quality is low

environmental issues and economic decisions in developing countries abstract this paper explains the key role of environmental economics in incorporating environmental concerns into decision making and in facilitating the more efficient management of natural resources as a step toward sustainable development it reviews concepts and techniques for valuation of environmental impacts for use in conventional cost benefits analysis as well as key related aspects including environmental impacts of economywide policies multicriteria analysis risk and uncertainty and discount rate issues several developing country case studies are summarized which cover a range of practical valuation methods the evidence presented suggests that the valuation techniques for determining use values may be applied successfully in appropriate cases but examples involving nonuse values are rare the use of multiobjective desicion methods also needs to be explored where economic valuation is not feasible

compensating variation consumer s surplus and welfare the compensating variation was defined by j r hicks 1942 as the amount one would have to deduct from a person s income to make him just as well off after a change in prices and income as he had been in the initial situation if the compensating variation is positive the individual is better off under the new situation since the compensating variation furnishes a uniquely defined numerical cardinal indicator of welfare improvement it provides an implicit ranking of alternative prospective situations not only relative to the initial situation but also relative to each other in practice this appears to be how this and other tools of cost benefit analysis are actually used one is interested in knowing not only whether a particular bridge or a particular excise tax will lead to an improvement in welfare but which out of a set of alternative bridges or alternative tax systems will improve welfare the most 1 in this paper we analyze conditions under which the compensating variation can be validly used in this generalized sense these turn out to be precisely the same as conditions previously derived see our 1976 paper for the valid use of consumer s surplus as a welfare measure in our final section we analyze the problem of deriving the generalized equivalent and compensating variations either exactly or approximately from observable demand functions by means of generalizations of or alternatives to consumer s surplus

welfare implications of community forest plantations in developing countries the orissa social forestry project community forest plantations are a common intervention in developing countries we use household and remote sensing data from orissa india to estimate welfare effects of community forest plantations in terms of the value of decreased collection times plantations afford users a selection model accounting for possible jointness in site location and productivity is used to estimate collection production functions for different household labor categories in natural and community forests two measures of an opportunity cost of time are used to determine welfare effects of time saved due to community forests we find access to community forests is important to marginal productivity of different labor categories but to different degrees highlighting the need to disaggregate household data when analyzing these interventions we also find substantial welfare improvements from time savings for many households and villages

tests of rationality neutrality and market efficiency a monte carlo analysis of alternative test statistics abstract this paper examines the small sample properties of three testing strategies used to analyze the rationality monetary neutrality and market efficiency hypotheses we focus on the original two step barro test of the mre hypothesis formed entirely from ols results a test that employs the correct variance covariance formulae for these two step estimates and mishkin s fimle testing framework each test is examined under likely model respecifications the findings highlight the extensive bias incurred by drawing inferences from simple unadjusted two step estimates and reveal the relative power of all tests in identifying alternatives to the null hypotheses

what do income tests tell us about the gap between wta and wtp for public goods abstract theory relates the gap between wta willingness to accept compensation and wtp willingness to pay to the income elasticity of wtp it has been suggested that empirical estimates of the income elasticity of wtp can therefore be used to test whether an observed gap between wta and wtp is consistent with rational behavior we examine this issue for the case of non market public goods we identify the theoretically appropriate tests of income sensitivity and examine conditions for valid income sensitivity tests we show that income tests may provide false signals in common settings indicating an inconsistency where none exists

money supply announcements interest rates and foreign exchange abstract this paper presents a test of the joint hypothesis that money supply announcements affect the real interest rate and that changes in the real interest rate affect the exchange rate in the short run the test results are consistent with the joint hypothesis for example it is found that announcement of an unexpected jump in the money supply is accompanied by an increase in interest rates and an appreciation of the dollar if the rise in interest rates was entirely due to higher inflationary expectations the dollar should not appreciate

bootstrapping in applied welfare analysis bootstrapping procedures are used to estimate the statistical properties of common empirical welfare measures results from a monte carlo experiment indicate that welfare estimates such as marshallian consumer surplus often exhibit significant bias standard errors of welfare estimates are found to often exceed the magnitude of the point estimate for typical cross section data sets and are generally larger than the difference between comparable hicksian and marshallian measures precision of welfare estimates can be markedly enhanced through generating larger data sets obtaining better model fits and through imposition of innocuous inequality restrictions on the demand function parameters

welfare measurement in the household production framework the household production approach to consumer behavior developed from the work of gary becker william gorman and kelvin lancaster has considerable descriptive appeal in modelling the decisions of households the approach derives from the observation that households frequently purchase market goods that do not yield utility directly but are combined to produce commodity service flows which the household values thus observed behavior is determined by household production technology as well as by tastes the advantage of this distinction is that we can pose reasonable hypotheses about characteristics of technology though we rarely possess useful a priori information regarding tastes the putative advantages of the household production approach are questioned on empirical and conceptual grounds by robert pollak and michael wachter 1975 they show that jointness in production or nonconstant returns to scale cause implicit commodity prices to depend on both tastes and technology raising serious econometric difficulties in the estimation of commodity demand functions in addition since commodity prices become functions of the commodity bundle consumed the analogy to traditional demand theory breaks down joint production occurs when a good enters several production processes simultaneously or equivalently when a good in one production process also enters directly into the individual s utility function the most common example is time which provides the context for all production processes and is often associated with the production of several commodities simultaneously since joint production in the household is likely to be pervasive the critique by pollak and wachter cannot be ignored in response to the comment by william barnett pollak and wachter 1977 suggest dispensing with the notion of commodity prices and treating the demand for commodities as a function of goods prices this approach confounds tastes and technology but it eliminates the troublesome concept of commodity prices as parameters when in fact they are likely to be endogenous in this paper we show that results from positive analysis such as the critique by pollak and wachter have implications for the use of the household production framework for welfare analysis the household production function approach has had considerable appeal for measuring welfare effects of public actions in the environmental and natural resource areas gardner brown john charbonneau and michael hay elizabeth wilman yet traditional approaches to welfare measurement are frequently inapplicable we argue that welfare measurement in this framework is complicated by the difficulties of unravelling tastes and technology we extend pollak and wachter s results by demonstrating that marshallian demand functions for commodities cannot be uniquely defined thus marshallian functions cannot be used to derive exact compensated functions in the manner of jerry hausman and of george mckenzie and i f pearce nor can compensating and equivalent variation measures be bounded by marshallian consumer s surplus estimates following robert willig in fact duality results that normally allow us to move between marshallian and hicksian functions are not assistant and associate professors respectively department of agricultural and resource economics university of maryland college park md 20742 this paper is scientific article no a3404 contribution no 6476 of the maryland agricultural experiment station we wish to thank darrell hueth james opaluch v kerry smith and elizabeth wilman for comments on an earlier draft

australian monetary growth and short term nominal interest rates an interest parity efficient markets approach the relationship between monetary growth and nominal interest rates continues to attract considerable attention in the literature mishkin 1982 has found that by explicitly imposing market efficiency in an interest rate model for the us empirical analysis does not support the keynesian proposition that increases in monetary growth are associated with reductions in short term rates in this paper a similar theoretical structure is used but unlike mishkin explicit account is taken of the fact that australia s capital market is closely integrated with international money markets incorporating this into the interest rate model indicates there is some empirical support for the keynesian proposition in the australian case the analytical model also incorporates a measure of interest rate volatility to account for the risk premium present in the forward rate for 90 day bank bills

contingent valuation techniques for assessing environmental impacts further evidence abstract this paper provides further evidence on the development and application of the iterative bidding technique used to assess environmental impacts three specific issues the hypothetical nature of the survey technique the questionnaire information structure and the bidding procedure starting point are examined theoretically and empirically to determine their effect on individual bid behavior the empirical results indicate that the importance of these influences may have been overstated in earlier studies

wage setting measures a survey and assessment wage setting has been one of the most heavily studied institutions in the field of comparative political economy over the past two decades and quantitative measures of wage setting arrangements have played a major role in this research yet the proliferation of such measures in recent years presents researchers with a sizable array from which to choose in addition some scholars are rather skeptical about the validity and or reliability of these measures this article offers a survey and assessment of fifteen wage setting measures it attempts to answer questions about 1 how these indicators differ from one another in conceptualization and measurement strategy 2 which are the most valid and reliable 3 the strengths and weaknesses of measures of wage centralization versus those of wage coordination 4 particular countries or time periods for which there are noteworthy discrepancies in scoring 5 how sensitive empirical findings are to the choice of wage setting measure

internationalization and the social democratic model crisis and future prospects this article examines the crisis of the social democratic model in the four countries austria norway finland and sweden in which social democracy was most successful in maintaining and even extending its two central achievements full employment and the institutional welfare state through the end of the 1980s four major conclusions emerge from the analysis first supply side measures more so than demand management were central to the employment and growth models pursued by social democracy prior to the early 1970s second the increasing trade openness contributed little to the recent problems of social democracy by contrast financial internationalization and deregulation and the multinationalization of capital undermined important features of the supply and demand sides of the models third changes in the international and domestic economies have weakened centralized bargaining fourth governments in the three nordic countries made serious mistakes in economic policy which greatly aggravated

the effect of money shocks on interest rates in the presence of conditional heteroskedasticity most current empirical work finds no evidence that money shocks lower interest rates we show that these nonresults are mainly due to a failure to model the conditional heteroskedasticity of interest rates autoregressive conditional heteroskedasticity arch models find a significant liquidity effect where ordinary least squares ols models do not the existence of a liquidity effect is found using different models and sample periods when arch models are used in estimation but never when ols is employed

on measuring the value of a nonmarket good using market data we use line integral theory to lay out in a more general theoretical framework the conditions under which it is possible to measure with market data the welfare effects of a change in a nonmarket good we present in detail a numerical method of measuring the value of nonmarket goods using market data under either weak neutrality or weak complementarity our numerical method is more flexible than the existing analytical method because it can be used with any well behaved marshallian demand function and can be used even when the willig condition does not hold

markets and the measurement of value consumer s surplus and the hicksian measures of compensating and equivalent variation have a long history in empirical economic analysis however at both the theoretical and the empirical level economists psychologists and public choice theorists have not been able to reach a significant consensus regarding the usefulness of these measures economic theorists have only recently dissected the differences which exist between alternative welfare measures in a systematic and transparent fashion in willig 1976 hausman 1981 and takayama 1984 the role of income in determining the correct theoretical measurements of compensating and equivalent variations was exposed during this same period of time theoretical results obtained by the psychologists kahneman and tversky 1979 indicated that the fundamental structure of preferences upon which the theoretical economic results are based is flawed the so called prospect theory of decision developed by these authors indicated that measured of welfare based upon payment will differ from measures of welfare based upon compensation because of the fact that individuals will value losses at a greater marginal rate than gains this difference was then predicted to dominate any income effect important in the economist s model finally this period recorded the emergence of many demand revealing processes which provide individuals with appropriate incentives to accurately reveal their preferences as summarized in coursey and schulze 1986 one interpretation of the literature on incentive compatibility suggests a set of well defined guidelines for improving both the accuracy and validity of compensating and equivalent variation measures these differences in professional preferences regarding what is important in improving the accuracy of economic welfare measurements led john

welfare losses due to market power hicksian versus marshallian measurement this paper warns against the use of marshallian welfare loss in applied analysis of market power we show how to compute the hicksian deadweight loss from an ordinary demand then from an experiment using real data on twenty one sectors of the french food industry we find that the marshallian deadweight loss poorly approximates the exact hicksian measure hence it is advisable to use the latter in applied welfare analysis copyright 2001 oxford university press

on the measurement of welfare for market and nonmarket goods a numerical approach extending vartia s 1983 framework the paper presents a simple numerical approach to the measurement of welfare for market and nonmarket goods on the basis of an incomplete mixed demand system the method allows the determination of exact welfare measures it provides a flexible and well founded alternative to ad hoc methods based on consumer surplus

a note on unanticipated money growth and interest rate surprises mishkin and makin revisited the relationship between monetary expansion and interest rates has long been an important macroeconomic issue friedman 1 hypothesized a dynamic adjustment process where the interest rate initially falls due to a liquidity effect then gradually rises in response to increased money demand higher prices and expectations of higher future inflation the relative size of these effects and the speed of the adjustment process are empirical questions that have recently received some attention in rational expectations econometric models in a recent article mishkin 5 found that interest rate and money growth surprises have a significant positive correlation makin 3 later published a paper where the correlation is negative and significant makin explained these contradictory findings as a result of the different method each uses to measure interest rates

what marshall didn t know on the twentieth century s contributions to economics some of this century s many valuable contributions to economics like macroeconomics econometrics and game theory are widely recognized however arguably equally important is the enhanced role of empirical study permitted by more abundant data and improved methods also insufficiently recognized are the increased rigor and use of applied economics in public finance regulation corporation finance etc employing abstract theory and sophisticated data analysis the striking contrast with earlier intuitively based applied economics and empirical study is illustrated comparison with marshall s principles also indicates that except for macroeconomics remarkably little space in today s texts deals with some of the rich contributions of this century what has twentieth century economics accomplished a great deal as will be shown here but the discussion needs an illuminating starting point in 1946 after arriving at the london school of economics as an entering graduate student 1 i soon found that in

willingness to pay and willingness to accept how much can they differ comment i agree with the point made by edoh y amiran and daniel a hagen 2003 that there can be a substantial or even infinite divergence between the wta and wtp for a public good even where there is a nonzero elasticity of substitution between market goods and the public good provided that the indifference curves are asymptotically bounded with respect to market goods in the manner they describe this is an important point they are also correct to point out that the elasticity of substitution is a local concept whereas their asymptotic boundedness condition applies also for discrete changes my 1991 paper used a local analysis because it was following the structure of the analysis in robert d willig 1976 and alan randall and john r stoll 1980 i wanted to show that while randall and stoll appeared to extend willig s local result on wta versus wtp from price changes to changes in the quantity of a public good the relevant elasticity was in fact different and involved the substitution elasticity as well as the income elasticity i view these points by amiran and hagen as not two separate results but essentially the same result their asymptotic boundedness condition generalizes my zero elasticity of substitution condition to discrete changes the asymptotic boundedness condition can be expressed as follows assuming a bivariate utility function u x q and given a reference point x q associated with a reference utility level u u x q there exists some q q such that for all q q there exists no x such that u x q u in other words no amount of x can substitute for the reduction in public good from q to q q in the case of a zero elasticity of substitution q q but as amiran and hagen show in their theorem 1 this is unnecessarily restrictive when dealing with a discrete reduction in q furthermore their theorem 2 can be viewed as a special case of their theorem 1 in which q 0 which makes q an essential commodity it is well known in consumer theory that the wta to avoid the loss of an essential market good is infinite their theorem 2 extends this result to the case of an essential nonmarket good but as their theorem 1 shows essentialness is not necessary for an infinite wta the boundedness condition is the key and this implies a fundamental lack of substitutability between money market goods and the public good

an integrated view of tests of rationality market efficiency and the short run neutrality of monetary policy abstract this paper analyzes an important class of models in which expectations play an important role topics included in the analysis are tests of 1 rationality of forecasts in either market or survey data 2 capital market efficiency 3 the short run neutrality of monetary policy and 4 granger causality in macroeconometric models the common elements of these tests are highlighted in particular cross equation tests for rationality or the short run neutrality of money are shown to be equivalent to more common regression tests in the literature these results demonstrate that the exact specification of the relevant information set used in rational forecasts is not necessary for the cross equation tests to have desirable asymptotic properties also discussed are the conditions for identification of coefficients and testability of hypotheses

public monopoly and economic efficiency evidence from the pennsylvania liquor control board s entry decisions we estimate a spatial model of liquor demand to analyze the impact of government controlled retailing on entry patterns in the absence of the pennsylvania liquor control board the state would have roughly 2 5 times the current number of stores higher consumer surplus and lower payments to liquor store employees with just over half the number of stores that would maximize welfare the government system is instead best rationalized as profit maximization with profit sharing government operation mitigates but does not eliminate free entry s bias against rural consumers we find only limited evidence of political influence on entry jel d42 d72 l11 l12 l43 l81

consumer s surplus without apology the purpose of this paper is to settle the controversy surrounding consumer s surplus and by so doing to validate its use as a tool of welfare economics i will show that observed consumer s surplus can be rigorously utilized to estimate the unobservable compensating and equivalent variations the correct theoretical measures of the welfare impact of changes in prices and income on an individual i derive precise upper and lower bounds on the percentage errors of approximating the compensating and equivalent variations with consumer s surplus these bounds can be explicitly calculated from observable demand data and it is clear that in most applications the error of approximation will be very small in fact the error will often be overshadowed by the errors involved in estimating the demand curve the results in no way depend upon arguments about the constancy of the marginal utility of income consequently this paper supplies specific empirical criteria which can replace the apologetic caveats frequently employed by those who presently apply consumer s surplus moreover the results imply that consumer s surplus is usually a very good approximation to the appropriate welfare measures to preview below i establish the validity of these rules of thumb for a

wage setting institutions and pay inequality in advanced industrial societies the distribution of pay differs significantly across countries and over time among advanced industrial societies in this paper institutional and political determinants of pay inequality are studied in sixteen countries from 1980 to 1992 the most important factor in explaining pay dispersion is the level of wage setting i e whether wages are set at the level of the individual the plant the industry or the entire private sector the impact of centralization is the same whether centralization occurs via collective bargaining or via government involvement in private sector wage setting the concentration of unions and the share of the labor force covered by collective bargaining agreements also matter after controlling for wage setting institutions other variables such as the governing coalition the size of government international openness and the supply of highly educated workers have little impact economic political and norm based explanations for the association of centralization with egalitarian outcomes are discussed

despairing over disparities explaining the difference between willingness to pay and willingness to accept this paper examines the three major explanations for the disparity between willingness to pay wtp and willingness to accept wta observed in contingent value surveys and laboratory experiments a belief that the results must be biased in some fashion hanemann s 1991 substitutes hypothesis and the loss aversion model proposed by tversky and kahneman 1991 starting from the assumption that individuals make utility maximizing choices we develop structural equations that yield parametric tests of the hypotheses within a single non experimental framework the approach is flexible enough to incorporate a variety of functional form and distributional assumptions and can be applied to either data from either open ended bids or dichotomous choice questions the usefulness of the approach is demonstrated using data from a survey that asked both wtp and wta questions the results provide weak support for loss aversion

the impact of money on short term interest rates this study reviews empirical evidence from four research methods related to the impact of money on short term nominal rates the studies consistently fail to find evidence supporting the much hypothesized short term negative relationship between money and nominal rates since at least april 1975 reasons for the absence of a negative relationship include the tendency of financial markets to anticipate corrective action by the fed whenever ml deviates from targeted growth ranges and a rapid adjustment of inflationary expectations to changes in money growth

analysing rationing policies drought and its effects on urban users welfare analysing rationing policies during drought the aim of this paper is to study the impact on consumers of rationing policies implemented during water shortages water scarcity gives rise to the need for rationing and various methods including supply cutoffs can be used a model is devised to quantify the welfare losses associated with qualitive and quantitive restrictions based on virtual prices and using the consumer surplus as a welfare measurement welfare variations for different users have been calculated to achieve the aim information relative to seville spain has been used analysing the drought period that took place in the first half of the 1990s it has been possible to observe the main source that led to welfare losses for each kind of user

are forign exchange intervention and monetary policy related and does it really matter the relationship between foreign exchange intervention and monetary policy underlies the question of whether sterilized interventions can affect the exchange rate in this article the author examines this relationship using data on u s foreign exchange interventions from 1985 to 1990 recently made publicly available she examines whether interventions could be viewed as signaling changes in future monetary policy variables the author also considers whether changes in monetary policy may induce interventions in an effort by central bankers to lean against the wind of exchange rate movements interestingly she finds evidence both that interventions help predict monetary policy variables and that monetary variables help predict interventions copyright 1995 by university of chicago press

government financing decisions and asset returns abstract this paper presents an empirical investigation of the relation between government financing decisions and asset returns in particular the focus is on whether a substitution of debt financing for tax financing of a given level of expenditures is associated with an increase in interest rates the paper brings a different perspective to empirical investigations of government fiscal policies by examining the response of asset prices in an efficient capital market to such policies rather than focusing on aggregate consumption behavior the results are consistent with the idea that asset prices are unrelated to how the government finances its expenditures the results however also indicate that the capital market is not indifferent with respect to the level of government expenditures as higher interest rates are associated with increases in government purchases

monetary union and wage bargaining institutions in the eu extrapolating from some member state experiences this article considers the question of how monetary union in the eu is likely to impact the preferences of governments employers and unions regarding the organization of wage bargaining european monetary union involves a decentralization of wage bargaining centered at the national level in relation to monetary policy centralized at the european level drawing on recent literature and on the experience of two member states italy and spain which prior to emu underwent periods of intense bargaining fragmentation the author argues that the imposition of restrictive monetary policy in a fragmented wage bargaining context in which workers nonetheless have substantial bargaining rights tends to have perverse effects these effects ultimately led governments and bargaining actors in italy and spain to seek a reorganization of bargaining that gave national actors greater control over wage setting the article considers to what extent a similar dynamic might play out in the euro zone

a review article the case against the use of the sum of compensating variations in cost benefit analysis this paper presents a case against the use of the sum of compensating varia tions as a cost benefit test we argue that 1 the ethical judginents implied by the test are not defensible 2 positive sums of compensating variations occur without potential pareto improvements resulting in social preference reversals without simultaneous scitovsky re versals 3 when lump sum transfers are feasible a positive sum of compensating variations is necessary but not sufficient for a potential pareto improvement 4 in order to eliminate preference reversals and intransitivities all households must have almost identical quasi homothetic preferences a condition that is not satisfied in real economies
