compensating wage differentials in stable job matching equilibrium abstract this paper studies implicit pricing of non wage job characteristics in the labor market using a two sided matching model it departs from the previous literature by allowing worker heterogeneity in productivity which gives rise to a double transaction problem in a hedonic model deriving sufficient conditions under which assortative matching is the unique stable job worker matching we show that observed wage differentials between jobs reflect not only compensating wage differentials but also worker productivity gaps between the jobs we find that the job worker matching pattern determines the extent to which compensating wage differentials are confounded with the worker productivity gap effect

green goals and full employment are they compatible abstract two empirical correlations are studied one between economic growth and environmental impacts and the other between the lack of economic growth and unemployment it is demonstrated that at a global level economic growth is strongly correlated with environmental impacts and barriers to fast decoupling are large and numerous on the other hand low or negative growth is highly correlated with increasing unemployment in most market economies and strategies to change this lead to difficult questions and tradeoffs the coexistence of these two correlations which have rarely been studied together in the literature on green growth degrowth and a growth justifies ambivalence about growth to make key environmental goals compatible with full employment the decoupling of environmental impacts from economic output has to be accompanied by a reduction of dependence on growth in particular strategies to tackle unemployment without the need for growth several of which are studied in this article need much more attention in research and policy

panel tests of okun s law for ten industrial countries donald g freeman i introduction okun s law describes an empirical regularity between unemployment and real output growth each extra percentage point in the unemployment rate above four percent i e full employment has been associated with about a three percent decrement in real gnp okun 1962 9 1 okun s law has proved to be one of the more durable relationships in modern macroeconomics and is now often presented as an element of core beliefs as in textbooks by hall and taylor 1993 77 and in policy discussions by blinder 1997 durability and simplicity being relatively scarce commodities in macroeconomics okun s law is appealing as a shorthand guide to policy outcomes whether okun s law travels well is another question cross country comparisons of the relationship between unemployment and output have been estimated for other countries by knoester 1986 paldam 1987 and moosa 1997 among others but magnitudes vary depending on country and time period estimates in these papers of the increase in output growth associated with unemployment reduction of one percent range from a low of around two percent in the u s and canada to three to five percent in europe to more than 10 percent in japan with estimates for europe tending to be higher for more recent time periods because of the way that okun s law is framed tests of its proposition involve two imposing empirical problems first as usually stated the law refers to the relationship between departures of real gdp 2 and unemployment from their long run or equilibrium trends often referred to as potential gdp and the natural rate of unemployment respectively these equilibrium trends must be estimated either by time series methods as in moosa 1997 or by construction using a modified production function approach in which potential output is estimated using fully employed inputs as in gordon 1984 or adams and coe 1989 either of these fapproaches invites considerable criticism of assumptions and methods see for example the comments of clark 1984 and of baily 1984 on gordon 1984 second in formulating his law okun seems clearly not to be referring to a ceteris paribus relationship between changes in the unemployment rate and changes in real gdp writing later okun posited that other factors and inputs would be changing pari passu with employment the 3 percent result from a reduction of one percent in the unemployment rate implies that considerable output gains in a period of rising utilization rates stem from some or all of the following induced increases in the size of the labor force longer average weekly hours and greater productivity okun 1970 p 140 thus a complete specification of the effect of changing unemployment rates on output would include factors such as capital inputs labor hours and participation rates all measured as deviations from long run trends this article addresses these two obstacles by using a recent trend cycle decomposition developed by baxter and king 1999 to measure gaps in output unemployment capital stock and the labor force the baxter king bandpass filter extracts the trend component of economic time series by eliminating both high frequency those less than two years and low frequency more than eight years components it is both flexible and easy to implement by using the bandpass filter to filter all the time series using the same methodology this paper departs from previous research of prachowny 1993 and attfield and silverstone 1997 incorporating capital and labor to augment estimates of okun s law additionally using the bandpass filter allows the estimates in this article to incorporate more timely data reflecting the shift to lower levels of unemployment in the u s and higher levels of unemployment in europe and japan during the 1990s the latest year of observation for the constructed data sets of gordon and of adams and coe used for example by prachowny 1993 and attfield and silverstone 1997 is 1988

from production based to consumption based national emission inventories abstract under the united national framework convention of climate change unfccc countries are required to submit national emission inventories nei to benchmark reductions in greenhouse gas ghg emissions depending on the definition and system boundary of the nei the mitigation options and priorities may vary the territorial system boundary used by the unfccc has been critiqued for not including international transportation and potentially causing carbon leakage to address these issues past literature has argued in favour of using consumption based nei in climate policy this article discusses several issues in moving from the standard production based nei to consumption based nei first two distinct accounting approaches for constructing consumption based nei are presented the approaches differ in the allocation of intermediate consumption of imported products second a consistent method of weighting production based and consumption based nei is discussed this is an extension of the previous literature on shared responsibility to nei third due to increased uncertainty and a wide system boundary it may be difficult to implement consumption based nei directly into climate policy several alternative options for incorporating consumption based inventories into climate policy are discussed

estimating the general equilibrium benefits of large changes in spatially delineated public goods the purpose of this article is to report a new approach for measuring the general equilibrium willingness to pay for large changes in spatially delineated public goods such as air quality we estimate the parameters of a locational equilibrium model and compute equilibria for alternative scenarios characterizing the availability of public goods within a system of communities welfare measures take into consideration the adjustments of households in equilibrium to nonmarginal changes in public goods the framework is used to analyze willingness to pay for reductions in ozone concentrations in southern california between 1990 and 1995

the demand for residence site characteristics the analysis of residential site choice is the primary concern in urban economics research on this problem is deficient in that rigorous theoretical models concentrate almost exclusively on access to the central business district cbd in this decision process while empirical models have been specified in a manner that is inconsistent with standard demand theory although these models possess the power of simplicity they are unable to explain the non monotonic location patterns which characterize urban areas without resorting to ad hoc theorizing this article develops and tests a model which is consistent with demand theory and is also capable of explaining non monotonic location patterns the hedonic rent function is seen as an intermediate step in the analysis of location which allows one to construct the complete data matrix necessary for the estimation of a set of demand functions for location specific traits the analytical importance of the functional form of this hedonic function is briefly noted finally the empirical analysis notes the importance of children in determining residential preferences with special attention being directed to the endogeneity of children with respect to the process of residential choice the traditional location model is generally tested by regressing some transformation of the annual rental payments or alternatively property value r on access or lack of access to the city center acc a vector of other locational traits z income i and a race variable mc

on welfare measurement in cities this paper extends project evaluation in a spatial urban economy to consider the more general case of distortionary public finances if a local public improvement is financed at least in part by a distortionary property tax we show that residential land prices do not accurately measure the value of land improvements even when households are identical and the improvement is infinitesimally small the magnitude and direction of the measurement error will depend on the second order effects on aggregate demand via changes in population density at each location and on overall city size

hedonic methods for baskets of goods a b s t r a c t existing hedonic methods cannot be easily adapted to estimate willingness to pay for product character istics when willingness to pay depends on a very large basket of goods we show how to marry these methods with revealed preference arguments to estimate bounds on willingness to pay using data on purchases of seemingly impossibly high dimensional baskets of goods this allows us to use observed purchase prices and quantities on a large basket of products to learn about individual household s will ingness to pay for characteristics while maintaining a high degree of flexibility and also avoiding the biases that arise from inappropriate aggregation we illustrate the approach using scanner data on food purchases to estimate bounds on willingness to pay for the organic characteristic

measuring the social value of local public goods an empirical analysis within paris metropolitan area a non linear hedonic model is used to estimate the implicit marginal prices of 17 local public goods in a paris suburban area on an original data set of some 8200 housing units the results reveal a robust effect of local public school quality measured both by the fraction of junior high school students that are at least two years behind grade level and the student teacher ratio on house prices it is observed that housing owners marginal willingness to pay for reducing commuting time is roughly similar for public transportation than for car transportation another noticeable result is the complete capitalization of local taxes at a discount rate of 3 5 an illustration of the potential usefulness of the results for cost benefit analysis is also provided

hedonic prices and the benefits of public projects s scotchmer has shown that even if the population is homogeneous hedonic prices do not correctly measure long run benefit s of a large public project this paper examines the direction of err ors and shows that the use of cross sectional land rent differentials leads to overestimation of the benefits the short run benefits with fixed lot size are also considered copyright 1988 by the econometric society

okun s law in panels of countries and states this article contributes to the empirical literature of okun s law in three respects first in contrast to the limited data used in the existing studies we employ two extensive across countries and across states i e within a country panel data sets to investigate the validity of okun s law second the use of the pooled mean group pmg estimator permits us not to pre filter the data as often done in the current literature and can take into account the possibility of cointegration between unemployment and output third in addition to the short run relationship or cyclical components between unemployment and output we also estimate the long run linkage between these two important variables empirical results show that unemployment and output are long run cointegrated irrespective of using country or state level data moreover the unemployment output linkages are found to be negative and highly significant both in the short and long run our results not only confirm the validity of okun s law

ghg emissions gdp growth and the kyoto protocol a revisit of environmental kuznets curve hypothesis abstract the kyoto protocol attempts through political negotiations to guide participating industrialized countries greenhouse gas ghg emissions from a positive growing trend to reach a peak point or turning point and then be reduced to a negative growth that means the relationship between decreasing ghg emissions and economic growth may be described by an inverted u curve or called a bell shaped curve which is consistent with the concept of the environmental kuznets curve ekc hypothesis this research observed that the economic development and ghg emissions in economies in transition eits exhibit a hockey stick curve trend or called quasi l shape curve that also generates a lot of hot air which is significant to the implementation of the kyoto protocol in addition through the analysis of single country time series data and gdp data this research demonstrated that statistical data for most of the annex ii countries do not possess evidence that supports the ekc hypothesis for ghg emissions the results from this study also indicated that the 38 industrialized countries are unable to meet their targets under the kyoto protocol within the specified time period which are probably caused by the econometric method s inability to predict accurately the extents and development of innovative technologies and clean development mechanism cdm projects if the international community truly wants to reduce the ghg emissions the effectiveness of the existing international framework for emissions reduction needs to be reconsidered seriously and the global cooperation mechanism also needs to be greatly enhanced

general equilibrium benefits for environmental improvements projected ozone reductions under epa s prospective analysis for the los angeles air basin abstract this research demonstrates how locational equilibrium models can be used for benefit measurement with the detail required to match epa s benefit analysis for the first prospective analysis using the projected changes in ozone concentrations for 2000 and 2010 together with the sieg et al int econ rev forthcoming estimates for household preferences for housing education and air quality this paper measures general equilibrium willingness to pay for the policy scenarios developed for the prospective study as they relate to households in the los angeles area benefits are evaluated taking account at the household level of initial air quality conditions relocation based on changes in ozone and price changes the framework generalizes the partial equilibrium general equilibrium comparisons available with conventional computable general equilibrium and property capitalization models estimated general equilibrium gains from the policy range from 33 to 2400 annually at a household level in 1990 dollars

the relationship between production and unemployment in japan okun s law in comparative perspective abstract this paper studies the question whether the celebrated okun s law a relation between excess capacity and unemployment applies to the postwar japanese economy though the fitness of estimation is weak the coefficient that measures the responsiveness of the output gap to the unemployment rate is very large reaching 28 this large coefficient can be attributed to the elastic response in the female participation ratio to flexible working hours to the slow adjustment in employment and to changes in industrial structures the results are compared with those in the united states

the short run and long run benefits of environmental improvement abstract the social value of a nonmarginal improvement to amentities is not related to hedonic prices in a simple way furthermore hedonic price data do not completely reveal preferences in order to evaluate short run benefits of an improvement the rate of change of the hedonic price function must be normalized by a ratio of population densities to calculate long run benefits of the improvement one must calculate the responsiveness of population densities to the nonmarginal improvement a technique to do so is suggested

is there a core of practical macroeconomics that we should all believe with emphasis on the adjective practical and the normative verb should my answer to the question of this session is a resounding yes indeed i spent a good deal of time between january 1993 and january 1996 acting on the belief that there is such a core macro model so i certainly hope it exists this believable core model falls well short of perfection leaves many questions unanswered and is subject to substantial stochastic errors nonetheless it is both useful and extensively used in policy analysis where contact with reality is a necessity and you cannot beat something with nothing it also closely resembles but does not quite match the way macroeconomics is taught to beginning and intermediate but not to graduate students in this short presentation i will describe briefly the main practical elements that i think we should agree on without worrying too much about their theoretical underpinnings then i will turn to two critical failings of the standard macro model which cry out for theoretical and empirical repair my organizing principle is the textbook exposition that has been standard though not universal in teaching intermediate macroeconomics for years the question is how does it differ from the core model used in policy analysis

social welfare and income inequality in a system of cities abstract this paper develops a general equilibrium model of a system of core periphery cities to examine the main determinants of intra and inter regional income disparities the economy is populated by a continuum of homogeneous unskilled and heterogeneous skilled workers unskilled workers whose wages are determined competitively specialize in food production in local cities skilled workers whose wages are determined according to a nash bargain manufacture a high tech commodity in the metropolis we establish conditions under which this core periphery equilibrium spatial configuration emerges we show that both intra and inter regional income disparities are present the determinants of each type of disparity and the social welfare implications are fully investigated our results suggest that public policy programs that improve income equality may not be necessarily welfare enhancing

nonlinear budget constraints and consumer demand an application to public programs for residential housing abstract this study presents a methodology for exploiting the nonlinear hedonic nature of housing prices to estimate the compensated demands of households for particular housing attributes the methodology is employed to provide hicksian benefit measures of a particular housing subsidy program typical of those undertaken recently in developing countries

on the continuum approach of spatial and some local public goods or product differentiation models some problems abstract models with a continuum of consumers and locations such that each consumer can purchase goods in only one location are examined such models are common in the literature of the new urban economics an approximation by economies with a finite number of consumers is shown to fail in the first two examples the continuum economy equilibrium exists and is unique but the finite economy has many equilibria example 1 or none at all example 2 in example 3 the continuum economy has no equilibrium but the finite economy has one these three examples employ location dependent utilities the fourth example illustrates the conceptual difficulties that arise in approximation when transportation cost is introduced even with location independent utilities the results are related to the literatures concerning product differentiation and spatial economies

taking the u out of kuznets a comprehensive analysis of the ekc and environmental degradation unlike most environmental kuznets curve ekc studies which focus on narrow measures of pollution as proxies for environmental quality we test the validity of the ekc using the ecological footprint ef a more comprehensive measure of environmental degradation we find no empirical evidence of an ekc relationship between the ef and economic development and only limited support for such a relationship among the components of the ef in addition we discover that energy is largely responsible for the lack of an ekc relationship and that energy consumption levels would have to be cut by over 50 in order for a statistically significant ekc relationship to emerge from the data overall these results suggest that growth alone will not lead to sustainable development

hedonic prices and cost benefit analysis abstract hedonic prices have been used to evaluate the willingness to pay for attributes we reformulate the notion of hedonic price from a composite price on housing to a unit price on traded quantities in conformity with long run competitive equilibrium theory this formulation was suggested but not developed by rosen j polit econ 82 no 1 1974 34 35 by first characterizing an efficient allocation of consumers to space we show that hedonic unit prices can be understood as a bid rent function which supports the efficient allocation this is despite the fact that the lots over which consumers bid are themselves endogenous we show that unit hedonic prices reveal preferences in a manner different from composite hedonic expenditures

existence of a spatial equilibrium we prove the existence of a competitive equilibrium in a simple canonical model of spatial economics we emphasize the single difficulty introduced by the use of a continuum of agents to convexify the fundamental locational nonconvexity individual consumption bundles are not bounded above by the aggregate boundedness of initial resources

work sharing during the great depression did the president s reemployment agreement promote reemployment the president s reemployment agreement pra of 1933 directed firms to reduce workweeks during the great depression so existing jobs could be spread into additional employment opportunities similar work sharing policies have recently been implemented across europe in hopes of reducing unemployment i find that ceteris paribus the work sharing aspects of the pra created nearly 2 5 million new employment opportunities in around four months however the programme also required firms to raise hourly wage rates offsetting close to half of these gains furthermore most of the remaining employment gains were wiped out after cartel oriented industry specific codes of fair competition supplanted the pra

latent class model or mixed logit model a comparison by transport mode choice data this article applies two recently stated choice survey datasets of japan to investigate the difference between the latent class model lcm and the mixed logit model mlm for transport mode choice a detailed comparison is carried out focusing on comparing values of time savings direct choice elasticities predicted choice probabilities and prediction success indices furthermore a test on nonnested model is also utilized to help determine which model is superior to another one the results suggest that the lcm performs better than the mlm in both datasets
