liquidity effects and the monetary transmission mechanism several recent papers provide strong empirical support for the view that an expansionary monetary policy disturbance generates a persistent decrease in interest rates and a persistent increase in output and employment existing quantitative general equilibrium models which allow for capital accumulation are inconsistent with this view there does exist a recently developed class of general equilibrium models which can rationalize the contemporaneous response of interest rates output and employment to a money supply shock however a key shortcoming of these models is that they cannot rationalize persistent liquidity effects this paper discusses the basic frictions and mechanisms underlying this new class of models and investigates one avenue for generating persistence we argue that once a simplified version of the model in christiano and eichenbaum 1991 is modified to allow for extremely small costs of adjusting sectoral flow of funds positive money shocks generate long lasting quantitatively significant liquidity effects as well as persistent increases in aggregate economic activity

is there a global market for convertible bonds prior to 1984 the stock price reaction to announcements of convertible issue in the domestic market was significantly negative while the reaction to issues on the eurobond market was smaller in absolute value and not consistently negative after 1984 this difference in stock price reactions seems to have disappeared the difference in abnormal returns before 1984 cannot be explained by existing signaling models of convertible bond issues it is consistent however with the hypothesis that american firms captured some of the tax advantage of eurobonds relative to domestic bonds before the change in u s withholding taxes in july 1984 copyright 1992 by university of chicago press

is inflation always and everywhere a monetary phenomenon using a sample of about 160 countries over the last 30 years we test for the quantity theory relationship between money and inflation when analysing the full sample of countries we find a strong positive relation between long run inflation and the money growth rate the relation is not proportional however the strong link between inflation and money growth is almost wholly due to the presence of high or hyper inflation countries in the sample the relationship between inflation and money growth for low inflation countries on average less than 10 per annum over the last 30 years is weak

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

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

from groundless universalism to grounded generalism improving ecological economic indicators of human environmental interaction abstract ecological economics occasionally makes universal claims about how to understand and measure change in systems of human environmental interaction in terms of environmental policy one of the most influential universal concepts that has come out of the ecological economics literature recently is ecological efficiency or eco efficiency this article uses eco efficiency as a vehicle to illustrate that universal indicators of human environmental interaction are theoretically unfounded and practically problematic population ecology and neo classical economics are identified as two theoretical approaches that have contributed to the emergence of universal concepts such as eco efficiency the limited applicability of the approaches is highlighted by putting them in comparative context with approaches that make less universal claims namely systems ecology and institutional economics investigating indicators of human environmental interaction from disciplinary perspectives that are rarely found in indicator literature offers novel insights on what indicators are for and how they should be applied the article concludes with a call for scale sensitive generalization in the development of future indicators

interpreting the macroeconomic time series facts the effects of monetary policy existing theory and evidence on the effects of monetary policy are reviewed substantial room for disagreement among economists remains new evidence based on multivariate time series studies of several countries is presented while certain patterns in the data consistent with effective monetary policy are strikingly similar across countries others particularly the tendency of interest rate increases to predict high inflation are harder to reconcile with effective monetary policy

segmented trends and non stationary time series since the influential work of charles r nelson and charles plosser 1982 many empirical studies have concluded that macroeconomic time series are difference stationary this paper proposes the segmented trend model as an alternative in which the series is the sum of a nonstationary trend and a stationary cycle and where the trend shows infrequent shifts the paper proposes tests between the difference stationary and segmented trends models and applies these to the data of nelson and plosser in general the results indicate that prices are difference stationary but quantities follow segmented trend processes copyright 1989 by royal economic society

different ways of knowing a communicative turn toward sustainability abstract despite the urgency of the ecological crisis the steady continuation of environmental degradation suggests that new ways of interpreting problems and acting with environmental integrity may need to be considered this paper draws on a broad range of contemporary theory to argue that the conventional conceptualization of environmental problems has remained a largely disciplinary based exercise that has relied on abstracting the environmental issues from their real world complexity a practical articulation of the main environmental narratives reveals self referential discourses whose disciplinary based practices have insulated these approaches from a broad range of contemporary theorising and different ways of knowing the dominance of these approaches in environmental policy development has led to the continued acceleration of environmental degradation despite widespread political and social interest in its abatement this paper provides a critique of methodologies derived from the assumptions of instrumental rationalism and contemplates the potential for alternative communicative approaches and strategies for dealing with environmental policy development and implementation it is argued that a communicative approach to planning for sustainability represents a more appropriate strategy for mobilising a currently impotent environmental movement a communicative approach by explicitly dealing with the assumptions and motivations of contested positions in the sustainability debate it is argued offers the most pragmatic way of developing change strategies to deal with the complex issues surrounding environmental policy development and implementation

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

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

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

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

announcement effects of convertible bond loans and warrant bond loans an empirical analysis for the dutch market abstract this study investigates the announcement effects of offerings of convertible bond loans and warrant bond loans using data for the dutch market the event study analysis shows that announcement effects of convertible bonds are associated with positive but insignificant abnormal returns and that announcements of warrant bonds are associated with significant positive abnormal returns these findings are similar to the results for japanese hybrid debt as reported by kang et al 1995 kang j k kim y c park k j stulz r m 1995 journal of financial and quantitative analysis pp 257 270 and kang and stulz 1996 kang j k stulz r m 1996 review of financial studies pp 109 139 but they contrast with studies for the united states that generally find significant negative abnormal returns for convertible bond loans and insignificant negative abnormal returns for warrant bond loans our results cannot be attributed to differences in the corporate governance structures of the netherlands and the united states we find that the positive abnormal returns for the warrant bond loans are caused by the packaging of the announcements with other good firm specific news

ecological economics as a policy science rhetoric or commitment towards an improved decision making process on sustainability abstract with sustainability issues currently attracting increasing political and policy attention this paper examines the impact of the rise of ecological economics in the policy world and its potential influence on the decision making process this study emphasises that ecological economics development is coevolved with and modified to fit specific social economic political and cultural contexts as a policy science ecological economics is context sensitive and action oriented explaining why it is so and what to do about it has become imperative for ecological economists this paper attempts to address the questions such as what are the macroeconomic conditions and political processes that make the formulation and implementation of ecological economic policy possible how should this alternative social reality engage with the dominant decision making process does ecological economics provide the necessary means for prescribing policy measures to achieve sustainable development endeavouring to understand these dimensions of ecological economics has been a dynamic social process and understanding this complex process might provide an opportunity to bridge the divide between policy rhetoric and reality in practice rather than maintain the status quo in order to achieve an improved decision making process on sustainability it highlights the imperative to explicitly study the institutional setting through which sustainable development policy discourse is mediated

in search of the liquidity effect abstract a short run negative relationship between monetary aggregates and interest rates the liquidity effect is central to discussions of monetary policy this paper searches for this empirical relationship we investigate whether the characterization of the liquidity effect is sensitive to i changes in sample period ii conditioning the correlations on past information iii assuming money growth is exogenous and iv treating monetary changes as anticipated or unanticipated the correlations change substantially in each case we conclude that the traditional analysis and modern models which rely completely on demand side behavior cannot explain the observed correlations a successful characterization of the liquidity effect requires identification of both private and policy behavior

fiscal requirements for price stability maintaining price stability requires not only commitment to an appropriate monetary policy rule but an appropriate scal policy rule as well ricardian equivalence does not imply that scal policy is irrelevant except in the case of a certain class of policies ricardian policies the role of scal developments in inflation determination under a non ricardian regime is illustrated through an analysis of the bond price support regime of the 1940s a monetary scal regime with attractive properties would combine a taylor rule for monetary policy with nominal decit targeting as a scal policy commitment

corporate earnings and financings an empirical analysis this article examines the long term behavior of corporate earnings around three corporate financing events sales of common stock convertible bonds and straight bonds the article shows that earnings declined for all issuers and that more capital is raised the larger the earnings decline these findings indicate that external financings are motivated by earnings declines no evidence is found of a relationship between the size of the subsequent earnings downturn or the amount of capital raised and stock price reactions to the financing announcements these findings suggest that security sales did not systematically provide new information about either the magnitude of subsequent earnings downturn or the amount of financing copyright 1990 by the university of chicago

steps towards indicators of sustainable development linking economic and ecological concepts abstract conceptions of defining and measuring sustainable development can broadly be placed in two categories weak and strong sustainability the concept of weak sustainability is based on neo classical economic theory and assumes that manufactured and natural capital are close substitutes this means that costs of environmental deterioration e g forest damage can be compensated by benefits from manufactured capital e g income thus environmental damages are valued in monetary units the concept of strong sustainability denies the degree of substitution that weak sustainability assumes at least for some critical elements of natural capital this paper pledges for strong sustainability indicators especially for critical loads and critical levels since the costs and benefits of avoiding critical impacts have to be taken into account a combination of strong and weak sustainability indicators means a linkage of ecological physical and economic monetary approaches should be suggested

understanding the money prices relationship under low and high inflation regimes argentina 1977 2006 abstract we study the regime dependence of the money prices relationship focusing on argentina s experience over the last 30 years using descriptive and cointegration analysis we find that proportionality holds for the high inflation period but weakens once inflation lowers money velocity correlates positively with money growth under high inflation while this relation reverts under low inflation var analysis allows to identify the key role of inflation expectations in driving the short run dynamics of the money growth inflation relationship under high inflation although this relationship weakens under low inflation money continues to play a role in explaining inflation dynamics in argentina

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

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

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

live long and prosper collective action social capital and social vision abstract to understand the social driving forces that lead to environmental change we must account for the role of social interactions the development of norms of behavior and the institutionalization of rules and norms the development of social capital this paper demonstrates the utility of social capital theory by articulating linkages between human decision making at individual and collective levels and social vision an important research focus within the emerging ecological economics research tradition social capital theory clarifies relationships between social interactions and outcomes that contribute to the production of environmental quality public peace and economic prosperity necessary factors for long term social and ecological sustainability

an empirical analysis of incremental capital structure decisions under managerial entrenchment abstract we study incremental capital structure decisions of dutch companies from 1977 to 1996 these companies have made 110 issues of public and private seasoned equity and 137 public issues of straight debt managers of dutch companies are entrenched for this reason a discrepancy exists between managerial decisions and shareholder reactions confirming zwiebel american economic review 1996 1197 1215 we find that dutch managers avoid the disciplining role of debt allowing them to overinvest however the market reactions show that this overinvestment behavior is recognized we do not find a confirmation of the adverse selection model of myers and majluf journal of financial economics 1984 187 221 this is probably due to the entrenchment of managers and the prevalence of rights issues

an analysis of the wealth effects of japanese offshore dollar denominated convertible and warrant bond issues offshore dollar denominated equity linked issues were a more important source of funds for japanese companies during the 1980s than domestic equity and straight debt issues combined using a sample of japanese equity linked offshore issues from 1977 to 1989 we find that the announcement of these issues is accompanied by a significant positive abnormal return this contrasts with evidence that u s equity linked issues have a significant negative stock price reaction we provide an explanation for the difference in stock price reactions between u s and japanese issues that is based on the greater influence on managers security issue decisions of long term investors and banks in japan than in the u s

planning for sustainability as a learning concept abstract the major theme of the following discussion is the importance of a transdisciplinary approach to guide sustainability related planning and management activities the proposed approach involves much more than the usual interaction between partners from different disciplines a revised process is needed to allow real cooperation in sustainability planning this process will require a more open recognition of the subjective priorities that become the framework of sustainable development issues of various interest groups and disciplines the sustainable development agenda should be more geared towards learning processes than projected future outcomes learning is enhanced through a participatory framework inclusive of stakeholder interests insights from a broad range of disciplinary areas including the science of complexity sociology philosophy law economics and management are presented to support this position the conventional stranglehold of disciplinary thinking in policy circles limits the capacity of our decision makers to unravel the complexity of all real world environmental policy and management problems policy making needs to embody respect for that complexity and allow flexibility to promote perpetually evolving learning as a fundamentally transdisciplinary framework ecological economics has some prospect to represent these interests in a purposeful and necessarily pragmatic way

making the most of high inflation this article examines the relationship between the real effects of inflation and its level in countries with frequent episodes of high inflation the real effects are computed as asymmetric impulse responses of output to inflation separately in the regimes with different signs of the differences between the expected inflation and the predicted output neutral inflation it is found that with the increase in inflation such effects increase in the regime with the positive sign relatively to the effects in the regime with the negative sign it is also shown that this finding is valid for most countries with high inflation episodes where inflation is greater than 4 8 for at least 25 of quarterly observations this leads to a simple policy prescription that in economies with frequent high inflation episodes anti inflationary monetary decisions are least damaging for output if undertaken in the periods when the difference between the expected and output neutral inflation is negative

two illustrations of the quantity theory of money of two central implications of the quantity theory of money that a given change in the rate of change in the quantity of money induces i an equal change in the rate of price inflation and ii an equal change in nominal rates of interest the illustrations were obtained by comparing moving averages of the three variables in question using quarterly u s time series for the period 1953 77 readers may find the results of interest as additional confirmation of the quantity theory as an example of one way in which the quantity theoretic relationships can be uncovered via atheoretical methods from time series which are subject to a variety of other forces or as a measure of the extent to which the inflation and interest rate experience of the postwar period can be understood in terms of purely classical monetary forces the theoretical background of the study is reviewed very briefly as it is familiar material in the next section the data processing methods are described and rationalized in section ii the illustrations

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
