unions and family income inequality the effect of union wage gains of private sector blue collar workers on the size distribution of family incomes and the level of poverty in 1970 is examined in this paper collective bargaining wage gains are found to compress the distribution of income among union families when union and nonunion families are combined however the union impact on measured inequality is negligible due in part to the fact that on average middle income families reap the largest gains from collective bargaining the impact of union wage gains on the incidence of poverty also is very small

adjustment costs and indeterminacy in perfect foresight models abstract this paper suggests a method for resolving indeterminacy of equilibrium in perfect foresight models and applies it to several existing models quadratic adjustment costs are introduced into models with multiple equilibria and the limiting behavior of the resulting solutions is studied as the adjustment costs go to zero the method is shown to be useful in selecting among feasible equilibria in examples in which there is local indeterminacy

on the existence of sunspot equilibria in an overlapping generations model abstract the existence of sunspot equilibria is shown in a one commodity overlapping generations model without stationarity assumptions on preferences endowments or nominal taxes the essential assumption is that there is a continuum of perfect foresight equilibria the technique is also useful for constructing stationary sunspot equilibria when they exist consumption in a sunspot equilibrium is shown to lie within the range consistent with perfect foresight

natural resources curse or blessing are natural resources a curse or a blessing the empirical evidence suggests that either outcome is possible this paper surveys a variety of hypotheses and supporting evidence for why some countries benefit and others lose from the presence of natural resources these include that a resource bonanza induces appreciation of the real exchange rate deindustrialization and bad growth prospects and that these adverse effects are more severe in volatile countries with bad institutions and lack of rule of law corruption presidential democracies and underdeveloped financial systems another hypothesis is that a resource boom reinforces rent grabbing and civil conflict especially if institutions are bad induces corruption especially in nondemocratic countries and keeps in place bad policies finally resource rich developing economies seem unable to successfully convert their depleting exhaustible resources into other productive assets the survey also offers some welfare based fiscal rules for harnessing resource windfalls in developed and developing economies

unions and wage inequality the roles of gender skill and public sector employment we examine the changing relationship between unionization and wage inequality in canada and the united states our study is motivated by profound recent changes in the composition of the unionized workforce historically union jobs were concentrated among low skilled men in private sector industries with the steady decline in private sector unionization and rising influence in the public sector half of unionized workers are now in the public sector accompanying these changes was a remarkable rise in the share of women among unionized workers currently approximately half of unionized employees in north america are women while early studies of unions and inequality focused on males recent studies find that unions reduce wage inequality among men but not among women in both countries we find striking differences between the private and public sectors in the effects of unionization on wage inequality at present unions reduce economy wide wage inequality by less than 10 however union impacts on wage inequality are much larger in the public sector once we disaggregate by sector the effects of unions on male and female wage inequality no longer differ the key differences in union impacts are between the public and private sectors not between males and females syndicats et inegalites salariales importance du genre des habiletes et de l emploi dans le secteur public dans cet article nous examinons l evolution de la relation entre syndicalisation et inegalites salariales au canada et aux etats unis notre etude se fonde sur les changements recents et profonds de la composition de la main d uvre syndiquee historiquement les emplois syndiques etaient occupes par des hommes peu qualifies travaillant dans les industries du secteur prive avec le declin regulier de la syndicalisation au sein du secteur prive et son influence croissante au sein du secteur public la moitie des travailleurs syndiques fait desormais partie du secteur public ces changements ont ete accompagnes d une hausse spectaculaire du pourcentage de femmes parmi les travailleurs syndiques actuellement pres de la moitie des employes syndiques en amerique du nord sont des femmes tandis que les premieres etudes sur les syndicats et les inegalites portaient sur les hommes certaines plus recentes ont montre que les syndicats permettaient de reduire les inegalites salariales entre les hommes mais pas entre les femmes dans les deux pays nous avons decouvert des differences frappantes entre secteur prive et secteur public relativement aux effets de la syndicalisation sur les inegalites salariales aujourd hui les syndicats permettent de reduire les inegalites salariales de moins de 10 dans l ensemble de l economie neanmoins l influence des syndicats sur les inegalites salariale est bien plus forte dans le secteur public en decomposant les donnees par secteur les effets des syndicats sur les inegalites salariales entre hommes et femmes sont les memes en matiere d influence des syndicats les differences fondamentales se situent entre le secteur prive et le secteur public et non entre les hommes et les femmes

the concept of natural capital the natural environment is now commonly viewed as a form of capital asset or natural capital also included are ecosystems that provide important goods and services to the economy managing natural capital has consequences for sustainable development however there are contrasting weak versus strong sustainability views which in turn have implications for green accounting natural resource based sovereign wealth funds have emerged as key financial instruments for compensating resource depreciation with greater economy wide investments recent scientific evidence recommends demarcating safe operating spaces to limit exploitation of critical global biophysical subsystems or processes these challenges suggest that the concept of natural capital is pivotal to sound policy

measuring natural capital towards accounts for the uk and a basis for improved decision making the paper describes the ongoing project begun by the uk office for national statistics and the department for the environment food and rural affairs in 2011 to compile comprehensive natural capital accounts for the uk it describes the basis on which the accounts have been constructed discusses key issues which have arisen and presents the results to date it also sets out how restoration accounts for individual projects can not only facilitate conventional cost benefit analysis but also add to relevant material for decision makers more widely the paper describes how natural capital accounts can underpin well based decision making for example in implementation of the uk government s new 25 year plan for the environment in addition by providing information on one of the missing capitals such accounts can augment analysis of the behaviour of the economy generally

union effects on wage dispersion in canadian industry abstract this paper analyzes the effects that unions have on the dispersion of wages in canada the empirical results indicate that unions have a significant effect in reducing wage dispersion the standard deviation in hourly wages is smaller for unionized workers than it is for non unionized workers this result holds not only for the more general case but also for narrowly defined demographic industrial and occupational categories finally regression estimates indicate that the coefficients on the wage determining variables are smaller in the unionized sector

stationary sunspot equilibria in a finance constrained economy abstract stationary sunspot equilibria are shown to exist in a production economy with infinite lived agents when it is not possible to borrow against future wage income equilibrium fluctuations exhibit persistence over time scales of the same order of magnitude as observed business cycles an active fiscal policy that stabilizes aggregate money expenditures can prevent such fluctuations

secular changes in wealth inequality and inheritance data suggest that the distribution of wealth among households in the usa and uk has become more equal over the last century though at least for the usa the pattern may have reversed recently this paper shows that a model in which all households save for life cycle reasons and some for dynastic purposes as well offers a possible or partial explanation the model predicts rising cross sectional equality of wealth when longevity increases there may also be implications about very recent changes expansion of social security programmes and government deficits can lead toward more wealth inequality slower growth may do the same

the definition of stability in models with perfect foresight abstract frequently the stationary states of decentralized models with perfect foresight and more than one asset are saddlepoints in this note we develop a distinction between historical and nonhistorical variables then we use the distinction to define economic concepts of weak and strong local asymptotic stability which apply even for some saddlepoints we conclude with three examples

nonlinearity and chaos in economic models implications for policy decisions this survey paper discusses the policy implications that can be expected from the recent research on nonlinearity and chaos in economic models expected policy implications are interpreted as a driving force behind the recent proliferation of research in this area in general it appears that no new justification for policy intervention is developed in models of endogenous fluctuations although this conclusion depends in part on the definition of equilibrium when justified however policy tends to be very effective in these models copyright 1993 by royal economic society

wage inequality and varieties of capitalism this article draws on a new data set that enables the authors to compare the distribution of income from employment across oecd countries specifically the article conducts a pooled cross sectional time series analysis of the determinants of wage inequality in sixteen countries from 1973 to 1995 the analysis shows that varieties of capitalism matter the authors find that the qualities that distinguish social market economies from liberal market economies shape the way political and institutional variables influence wage inequality of particular interest to political scientists is the finding that the wage distributive effects of government partisanship are contingent on institutional context union density emerges in the analysis as the single most important factor influencing wage inequality in both institutional contexts

union effects on productivity evidence from western u s sawmills the authors conjecture that previous studies have tended to overestimate the productivity of union firms relative to nonunion firms due to inadequate controls for output quality and input usage important omissions if the higher cost of unionized labor leads to less labor intensive products and techniques to avoid those problems this study examines a fairly standardized commodity lumber and controls for detailed product attributes and inputs an analysis of data from a survey administered by the authors shows that unionized sawmills were between 12 and 21 less productive than nonunionized mills in fiscal year 1986 as predicted when product quality and raw material usage are not included in the analysis the estimate of union productivity is biased upward

positive freedom markets and the welfare state the comparative merits of market and certain distinguished non market resource allocation mechanisms have continually been at the centre of debate in economics and political philosophy doubtless it will remain there for here one faces the grandest of human concerns embracing as it does issues bearing on liberty and welfare the aspirations of people their potential and re alized capabilities and the fulfillment of their needs it enables us to see individuals in a social context to ask about the possible features of a civil society the obligations that people may have to themselves to one another and to agencies then again we are able to enquire into the obli gations that agencies have to people and to one another the extent to which responsibility needs to be delegated among offices and persons the role that dispersed information may play in an swers to these and so on the debate is central to any discussion of the kind of society we ought to aspire to be members of

returns to seniority in union and nonunion jobs a new look at the evidence in cross sectional data the positive association between seniority and earnings is typically much stronger for nonunion workers than for union workers a finding that seems inconsistent with the generalization that seniority is more important in the union sector than in the nonunion sector the authors of this paper show that standard estimates of the return to seniority are likely to be biased upward due to unmeasured worker heterogeneity job heterogeneity or both and they argue that this bias is likely to be larger in the nonunion sector than in the union sector when they correct for this problem in analyzing data on male blue collar workers for the years 1968 80 they find a larger return to seniority in the union sector than in the nonunion sector

stabilizing competitive business cycles abstract we study how stylized monetary proportional money transfers fiscal lump sum money transfers and public expenditure policies may eliminate endogenous deterministic cycles and stationary markov sunspot equilibria in a simple version of the overlapping generations model we also present new constructive methods for analyzing stationary markov sunspot equilibria in such a framework

legal restrictions sunspots and cycles abstract an economy in which legal restrictions prevent private agents from issuing close substitutes for money is examined specifically in a model with borrowing and lending agents are prevented from acquiring privately issued liabilities in amounts smaller than some minimum dollar denomination an economy is then constructed which has no sunspot equilibria absent such a restriction in the presence of the restriction however conditions sufficient to rule out equilibrium 2 cycles also imply the existence of stationary sunspot equilibria this is the case even though all agents have savings functions that are non decreasing in relevant rates of return

dynamic determinacy and the existence of sunspot equilibria this paper relates the existence of stationary sunspot equilibria in the vicinity of a conventional stationary state to the phase diagram surrounding the latter we find that the local condition required for a unique equilibrium path returning to the stationary state following any slight disturbance of initial conditions is also sufficient to exclude stationary sunspot equilibria in the stationary state s immediate vicinity in that sense an eigenvalue condition familiar from dynamic analysis can tell us something about the possibilities of local sunspot activity as well journal of

adjustment costs learning and indeterminacy abstract i compare the adjustment cost and learning approaches to resolving indeterminacy of perfect foresight equilibrium in a continuous time model with local indeterminacy rapid learning tends to select different perfect foresight equilibria of the original model than does the inclusion of vanishing adjustment costs this difference has implications for the dynamic response of the economy to unanticipated shocks

unions and nonunion wage dispersion previous research has found that union standard rate policies lower the dispersion of union wages and that unions indirectly raise nonunion wage levels as firms weigh the probability of unionizing and wage costs these two findings imply that unions lower the dispersion of nonunion wages since for a given payroll a nonunion firm can achieve the greatest reduction in the probability of unionism by giving raises to those who would benefit most from a union this hypothesis is confirmed on current population survey data taking into account the endogeneity of unionism ceteris paribus nonunion wage dispersion is lower in more highly unionized industries copyright 1987 by mit press

comparative statics and perfect foresight in infinite horizon economies does a pure exchange economy with an infinite time horizon have determinate perfect foresight equilibria when there is a finite number of infinitely lived agents equilibria are generically determinate this is not true with overlapping generations of finitely lived agents we ask whether the initial conditions together with the requirement of convergence to a steady state locally determine an equilibrium price path in this framework there are many economies with isolated equilibria many with continua of equilibria and many with no equilibria at all with two or more goods in every period not only can the price level be indeterminate but relative prices as well furthermore such indeterminacy can occur whether or not there is fiat money and whether or not the equilibria are pareto efficient this paper considers whether infinite horizon economies have determinate perfect foresight equilibria this question is of crucial importance if instead equilibria are locally indeterminate not only are we unable to make comparative static predictions but the agents in the model are unable to determine the consequences of unanticipated shocks the idea underlying perfect foresight is that agents expectations should be the actual future sequence predicted by the model if the model does not make determinate predictions the concept of perfect foresight is meaningless we consider two extreme cases the first with a finite number of infinitely lived consumers and the second with an infinite number of finitely lived consumers an overlapping generations model both are models of stationary pure exchange economies no production including the storage of goods between periods can occur these models are unrealistic but are the easiest to study extensions of the results of this paper to models with production infinitely lived assets and mixtures of the two types of consumers are presented by muller and woodford 29 when there is a finite number of infinitely lived consumers we argue that equilibria are generically determinate this is because the effective number of equations determining equilibria is not infinite but equal to the number of agents minus one and must determine the marginal utility of income for all but one agent generically near an equilibrium these equations are independent and exactly determine the unknowns when there are infinitely many overlapping generations this reasoning breaks down an infinite number of equations is not necessarily sufficient to determine

the impact of the minimum wage if workers can adjust effort abstract in traditional models a binding minimum wage creates a excess supply of low skilled workers for minimum wage jobs employment falls and some jobs are reallocated from high to low rent workers this disequilibrium cannot persist competition to secure the property rights to now scarce jobs undoes most of the effects of the minimum wage workers who attach the highest value to the jobs are willing to work harder to keep them marginal workers are squeezed out of the market as high rent workers ratchet up effort level this process erodes the rent conferred by the minimum wage but also increases the value of marginal product which reduces the size of the employment effect the minimum wage confers more money income on low skilled workers and creates some distortion in the optimum combination of wage rate and effort level under plausible conditions the minimum wage has little effect on rent employment output and profits

the integration of natural capital into development policies in response to the united nations sustainable development goals there has been a rising awareness of the need to address simultaneously the preservation of natural capital stocks and poverty alleviation at multiple scales focusing on tropical forest rich developing countries the article overviews the extent to which natural capital considerations are integrated into existing development policies and interventions the review finds that the explicit consideration of natural resources is left out of many commonly applied development interventions leading to suboptimal and unsustainable outcomes the interventions that do tackle both development and conservation goals are often not coordinated and are implemented at a site by site basis without providing the socially efficient levels of natural capital stocks or ensuring the long term sustainability of the development and conservation impacts bringing in perspectives from development economics environmental economics and applied conservation this article makes the case for a better integration of development and conservation goals in interventions in developing countries and outlines the emerging frontiers for research and policy

paying the professor sources of salary variation in academic labor markets using a set of 58 academic fields as distinct labor markets we examined the extent of wage variation within markets the degree to which wages vary is an indicator of market efficiency and of whether a market wage exists holding constant differences in human capital we found that the degree of wage variation in an academic labor market is negatively related to mobility within that market and positively related to the oversupply of labor we also found that as wage variation increases male female wage differentials also increase

the ecology of natural capital accounting natural capital is increasingly widely discussed and included in corporate and governmental accounts using a variety of different approaches and metrics here i argue that natural capital is fundamentally an emergent feature of structures and functions of the natural environment therefore its valuation and metrics for reporting on its condition and the way that it is represented in accounts need to reflect these defining features and not rest solely on measurable flows of goods and services natural capital is an asset and its many contributions to the economy and society often called ecosystem services are both malleable and adaptable their value changes with time and context as they become more or less important and relevant for particular purposes unlike most produced assets natural assets are multifunctional adaptable and resilient and within limits they have the capacity to regrow or reorganize themselves maintaining this capacity is therefore the key priority for a responsible owner or manager of natural assets currently most metrics for natural capital are based on the quality or quantity of flows of goods and services on the geographical distribution of particular ecosystems or land sea uses and by reference to ecosystem services delivered by particular ecosystems the advantages and disadvantages of these different approaches are discussed but i propose instead using the quality of fundamental ecological processes and functions which properly represent the functioning and capabilities of the natural capital system upon which society and the economy depend

this blessed plot when should capital gains on land be regarded as income national balance sheets for a number of advanced economies show land to be a valuable form of natural capital whose value has increased sharply over the last twenty years or so this paper investigates when or whether capital gains on land should be counted as a component of income while development projects can lead to increases in rental rates and land values it is shown that although the benefits any project should be counted as income increases in rental rates and land values should not normally be seen as additional real income however if land benefits from exogenous land saving technical progress the resulting capital gains can be seen as income applying the same principle to human capital it is shown on a steady growth path that these capital gains are equal to weitzman s 1997 growth premium in the relationship between income and sustainable consumption

trade unions in the production process reconsidered the effect of unions on productivity has become a controversial topic in recent years stimulated by the claim of harvard economists that unions tend to increase productivity through their collective voice institutional response role freeman and medoff 1984 chap 11 advocates of this view argue that unions on balance increase productivity in unionized enterprises by reducing labor turnover enhancing worker morale and cooperation providing efficient collective voice in negotiating workplace characteristics and grievance resolution and pressuring management into stricter efficiency the traditional view has been that unions impede productivity within unionized firms by limiting management flexibility by engaging in restrictive practices and featherbedding and by disrupting production through strikes strike threats and other adversarial tactics these opposing theoretical views have prompted a number of empirical studies to evaluate their relative importance the empirical literature continues to rely on an explicit production function approach initiated by brown and medoff 1978 there is a flaw in this approach however that renders econometric estimates based on it incapable of resolving the question of what impact unions may have on productivity the objection may be stated in the following way if all firms maximize profits and trade unions impose higher than competitive wage rates on unionized firms then the marginal productivity of unionized labor is necessarily greater than that of nonunion labor this is simply a restatement of the familiar firstorder conditions no amount of statistical control over managerial responses in the form of quality of workers and capital labor ratios

a review of the stern review on the economics of climate change the stern review calls for immediate decisive action to stabilize greenhouse gases because the benefits of strong early action on climate change outweighs the costs the economic analysis supporting this conclusion consists mostly of two basic strands the first strand is a formal aggregative model that relies for its conclusions primari ly upon imposing a very low discount rate concerning this discount rate aspect i am skeptical of the review s formal analysis but this essay points out that we are actual ly a lot less sure about what interest rate should be used for discounting climate change than is commonly acknowledged the review s second basic strand is a more intuitive argument that it might be very important to avoid possibly large uncertain ties that are difficult to quantify concerning this uncertainty aspect i argue that it might be recast into sound analytical reasoning that might justify some of the review s conclusions the basic issue here is that spending money to slow global warming should perhaps not be conceptualized primarily as being about consump tion smoothing as much as being about how much insurance to buy to offset the small change of a ruinous catastrophe that is difficult to compensate by ordinary savings

employee voice human resource practices and quit rates evidence from the telecommunications industry the authors draw on strategic human resource and industrial relations theories to identify the sets of employee voice mechanisms and human resource practices that are likely to predict firm level quit rates then empirically evaluate the predictive power of these variables using data from a 1998 establishmentlevel survey in the telecommunications industry with respect to alternative voice mechanisms they find that union representation predicts lower quit rates even after they control for compensation and a wide range of other human resource practices that may be affected by collective bargaining also predicting lower quit rates is employee participation in offline problem solving groups and in self directed teams no apparent association is found between quit rates and the availability of nonunion dispute resolution procedures regarding human resource practices higher relative wages and internal promotion policies predict lower quit rates and contingent staffing electronic monitoring and variable pay predict higher rates

unions and cooperative behavior the effect of discounting using union contract and industry wage survey data this article examines the effect of discounting on cooperative bargaining behavior by unions and firms game theory predicts that higher discount rates raise the temptation to defect from cooperation measures of cooperative behavior included the presence of merit pay incentive pay wage employment guarantees or labor management study committees discount rates were proxied by the relevant industry s failure rate failure rates generally had negative effects on cooperation industry wage survey results showed larger effects for union than non union establishments providing support for the union bargaining framework

is pattern bargaining dead this paper challenges the common belief that pattern bargaining largely ended in the 1980s applying a measure of pattern bargaining the dispersion of log wages to wage data drawn from the same data set that audrey freedman used in her widely quoted studies of this subject the author shows that the extent of pattern bargaining was actually greater in 1983 than in 1977 the evidence suggests that managers perceptions of changes in the bargaining process which are the basis for freedman s claim that pattern bargaining has eroded are inconsistent with actual changes in wage patterns

agriculture after brexit the paper considers the impact of the common agricultural policy cap on the uk and sets out three options for a new british agricultural policy after brexit these options are carrying over the subsidy regime with an emphasis on food security and self sufficiency maintaining the cap architecture but shifting more of the cap subsidies away from payments for land ownership towards more spending on environmental schemes and providing public money only for public goods the third option is advocated after a transitional path allows time for farmers to adapt

human capital risk and economic growth this paper develops a tractable incomplete markets model of economic growth in which households invest in risk free physical capital and risky human capital the paper shows that a reduction in uninsurable idiosyncratic labor income risk decreases physical capital investment but increases human capital investment growth and welfare a quantitative analysis based on a calibrated version of the model reveals that these effects are substantial and of the same order of magnitude as the effects of distortionary income taxation the analysis further suggests that government sponsored severance payments to displaced workers increase growth and welfare even if these payments have to be e nanced through distortionary income taxation

valuing the invaluable how much is the planet worth this article explores the valuation of natural capital by critically analysing alternative approaches to it it considers the problems associated with applying economic values to natural capital and the limitations of such exercises it examines different methods that are more familiar to accountants than economists of using what is sometimes termed an engineering approach to estimating the costs of maintaining and restoring existing assets it considers the arguments that are used to justify the two in particular it addresses the question of what we are seeking to do by determining the value of natural capital what is the question to which valuation is supposed to be the answer

unionization and cost of production compensation productivity and factor use effects unionization affects cost of production through compensation premia technology shifts and deviations from the least cost combination of inputs the first two are familiar but the last is not this article distinguishes the three effects illustrates the factor use effect and suggests that it may resolve several apparent inconsistencies union induced cost effects appear larger than those implied by union compensation and productivity differentials union compensation and productivity differentials suggest a larger effect on labor intensity of output than is observed and employers complain that union work rules reduce productivity when there is little evidence that this is so

unions wages and skills studies uniformly conclude that union wage effects are largest for workers with low measured skills longitudinal analysis using 1989 90 1994 95 cps matched panels produces union premium estimates equivalent across skill groups following appropriate sample restrictions and control for worker specific skills nlsy evidence on aptitude scores confirms that union workers with high measured skills have relatively low unmeasured skills differential selection by skill class and skill homogeneity in union workplaces result from employer and employee sorting in response to wage standardization union organizing where skills are homogeneous and unionized employers reluctance to hire the most as well as least able workers

equilibrium cycles in an overlapping generations economy with production abstract perfect foresight equilibrium trajectories of an overlapping generations model with production may include stable or unstable invariant closed curves these orbits are detected using the hopf bifurcation theorem where the parameter of bifurcation is purely technological the paper also proves that there is a stabilization policy that completely eliminates the cycle finally using a c e s production function it is shown that the range of values of the elasticity of substitution between capital and labor for which cycles may exist is bounded above

sunspot equilibria rational bubbles in a model of money in the utility function abstract sunspot equilibria are constructed in brock s 1975 model of money in the utility function serial correlations of real balances and the nominal interest rate in these equilibria can be either positive or negative the example here suggests that local sunspots are more likely to exist when the agent s discount rate is small and that serial correlations in local sunspots when they exist are inversely related to the rate of money growth it is also shown that stationary sunspots may exist even when equilibrium cycles do not

deficits and cycles abstract this paper shows that periodic equilibria may arise in a simple overlapping generations model with capital if the government follows a policy of fixing the value of the deficit rather than fixing the value of government debt then the difference equation that describes competitive equilibria may posses complex roots in the neighborhood of the golden rule stationary state one may show that if there exist parametric families of economies for which these roots change stability then locally there exists an invariant closed curve the paper provides two simple examples that generate such equilibria and it solves these examples numerically

union wage practices and wage dispersion within establishments this study analyzes establishment level data primarily to examine the effect of unionism on the wage structure within establishments the major finding is that within establishment dispersion of wages is significantly narrower in unionized than in nonunionized establishments a pattern the author attributes in large part to unions wage practices such as single rate or automatic progression modes of wage payment as opposed to merit reviews and individual wage determination the data also show that dispersion in average wages is narrower among organized plants but by more modest amounts than the within establishment differential overall the evidence suggests a major role for explicit union wage policies in explaining the dispersion of wages within firms and in the economy as a whole

natural capital assets systems and policies natural capital is a concept whose time has come but is in danger of being greenwashed to suit vested interests as has happened to sustainability it is a hard concept based upon assets rather than utility natural capital assets provide the foundations for positive freedom by providing for future generations capabilities and choices this is especially the case for renewable natural capital which can provide nature s bounty forever provided the assets are not driven below critical thresholds natural capital assets lend themselves to accounting to balance sheets and risk registers and require capital maintenance cost benefit analysis being partial and on a project by project basis has a limited role since the natural environment comes in systems and is less amenable to marginal analysis three principles are core to the design of natural capital policies these are public goods with public monies polluter pays and compensation in the form of net environmental gain

unionism and productivity in west virginia coal mining this study presents econometric estimates of the effects of unionism on productivity in 83 west virginia coal mines in the early 1920s the size detail and panel structure of the data set permit investigation of many possible links between unionism and productivity in contrast to the summary measures reported by most studies the results show that the union effect was not uniform across mines and cannot be represented by a simple shift parameter rather unionism significantly reduced productivity at small mines but not at large mines drawing on historical evidence the author ascribes this differential effect to systematic differences between small and large operations in the quality of management and union leadership

can union labor ever cost less this paper examines the effect of unions on efficiency by estimating cost function systems over three different sets of construction projects the results show that union contractors have greater economies of scale this gives them a cost advantage in large commercial office buildings but in school and hospital construction nonunion contractors have lower costs at all output levels despite the cost differences profits for nonunion contractors in school and hospital construction are no higher than those for union contractors because the burden of higher union costs is shifted to buyers

wage dispersion within firms and collective bargaining in spain abstract this paper analyses the determinants of bargained wage dispersion by professional groups within firms in spain estimations show that insider factors union density sales per employee and the average bargained wage level are the main determinants of wage dispersion

corporate natural capital accounting accounting is an important practical mechanism by which corporations are held to account for their performance and impact this is consequential for corporate responsibility for the conservation of natural capital while there is clear evidence of increasing corporate accounting and reporting with respect to aspects of natural capital however such efforts are at best nascent this is in part because the purpose and meaning of corporate natural capital accounting is not in itself well established and in part because existing institutional structures and incentives do not lend themselves to giving a full account of natural capital impact in this context the paper argues that there is essentially a need for natural capital accounting and reporting systems that serve two distinct purposes the first which is the more likely to be satisfied by existing market structures is oriented towards the informational needs of shareholders and is concerned with supporting a transition towards environmentally sustainable business models the second in contrast acknowledges that a shareholder oriented perspective constrains natural capital to be important if and only if its conservation privately affects shareholders which is unlikely to ensure an accounting that contributes to the conservation of natural capital as an end in itself this second purpose of strengthening corporate natural capital accountability is unlikely to be satisfied within existing market structures instead it stands in need of a regulatory solution

union density and varieties of coverage the anatomy of union wage effects in germany collective bargaining in germany takes place at either industry or firm level and bargaining coverage is much higher than union density the share of a firm s employees covered can vary between 0 and 100 suggesting that researchers should distinguish union density coverage at the firm level and coverage at the individual level using linked employer employee data the authors estimate ols and quantile regressions of wages on these dimensions of union influence they find that a higher share of employees in a firm covered by industrywide or firm specific contracts is associated with higher wages but find no clear cut effect on wage dispersion yet holding coverage at the firm level constant individual coverage is associated with lower wages and less wage dispersion higher union density reinforces the effects of coverage but for employees in firms without coverage density s effect is negative and thus compresses the wage distribution in firms without coverage

the impact of pension benefits on the distribution of earned income using standard measures of income inequality and detailed pension benefit information on participants in the 1983 survey of consumer finances scf the authors investigate how pension benefits affected the distribution of earned income the results suggest that private pensions increased annual income inequality relative to inequality observed in the distribution of wage income by only about 2 among all employed individuals but by 21 among unionized workers further analysis indicates that private pensions raised annual income inequality primarily by increasing the rate of return to tenure possibly through pension backloading setting accruals to grow when earnings rise near retirement and the increasing incidence of pensions with age private pensions had little effect on estimates of the distribution of expected lifetime income but the addition to the analysis of social security benefits public pensions strongly reduced inequality in that distribution a renewed interest in the distribution of income has developed recently as new evidence suggests that income inequality has worsened over the past twenty years researchers suggest several reasons for rising inequality including an increase in the incomes of well educated men relative to other groups for example juhn murphy and pierce 1993 demographic changes resulting from the entrance of the baby boom generation into the work force lawrence 1982 and a sectoral shift away from manufacturing and toward the ser

on the contract curve a test of alternative models of collective bargaining the traditional model of collective bargaining confines unions to settlements constrained by the employer s labor demand curve but an alternative model places wage employment outcomes on a contract curve that extends beyond the labor demand curve this paper derives a multidimensional hedonic contract curve model in which employment security provisions are used to maintain efficient bargains outside the employer s demand curve and distinguishes empirically between the contract curve and demand constraint models using data for public school teachers in new york state estimates clearly support the contract curve model over the demand constraint model by linking the gap between compensation and the value of the marginal product to the strength of employment security provisions

unionized construction workers are more productive this paper presents evidence on the effect of unionism on productivity in construction the linkages are distinct from those studied previously in industrial settings apprenticeship training and hiring halls probably raise union productivity while jurisdictional disputes and restrictive work rules lower it using brown and medoff s methodology union productivity measured by value added per employee is 44 to 52 percent higher than nonunion the estimate declines to 17 to 22 percent when estimates of interarea construction price differences are used to deflate value added occupational mix differences and possibly apprenticeship training account for 15 to 27 percent of this difference

wage effects of unionization and occupational licensing coverage in the united states recent estimates in standard models of wage determination for both unionization and occupational licensing have shown wage effects that are similar across the two institutions these cross sectional estimates use specialized data sets with small sample sizes for the period 2006 to 2008 the authors analysis examines the impact of unions and licensing coverage on wage determination using new data collected on licensing statutes that are then linked to longitudinal data from the national longitudinal survey of youth nlsy79 from 1979 to 2010 they develop several approaches using both cross sectional and longitudinal analyses to measure the impact of these two labor market institutions on wage determination the estimates of the economic returns to union coverage are greater than those for licensing statutes

a review of the stern review on the economics of climate change how much and how fast should we react to the threat of global warming the stern review argues that the damages from climate change are large and that nations should undertake sharp and immediate reductions in greenhouse gas emissions an examination of the review s radical revision of the economics of climate change finds however that it depends decisively on the assumption of a near zero time discount rate combined with a specific utility function the review s unambiguous conclusions about the need for extreme immediate action will not survive the substitution of assumptions that are consistent with today s marketplace real interest rates and savings rates

union effects on productivity profits and growth has the long run arrived this article interprets literature examining union effects on economic performance production function studies indicate small overall union impacts on productivity positive effects where they exist appear to result from management response to decreased profit expectations and from a natural selection process lower profitability among unionized firms is well established more interesting is the possibility that unions appropriate quasi rents deriving from long lived tangible and intangible capital the connection between unions investment behavior and productivity growth emerges as a particularly fruitful line of empirical inquiry although it does not encourage a sanguine view of unionism s long run impact

why unions reduce wage inequality a theory of domino effects numerous empirical studies show that unions reduce wage differences i demonstrate that their motive might be a mix of fairness and strategy maximizing the use of union bargaining power in the presence of efficiency wages unions can push primarily for raising the lowest wages and still not sacrifice higher wages much if the employers themselves increase higher wages to protect efficiency enhancing wage differences if these domino effects are strong enough then an egalitarian wage policy might even increase the median wage

wage settlements and wage setting results from a multi level model which dimensions of wage setting differ across establishments applying collective contracts and uncovered establishments the empirical analysis reported here utilizes german linked employer employee data for the years 1990 1995 and 2001 and is restricted to workers without supervisory functions in larger manufacturing firms results show that the expected wage of an average worker is higher in firms applying collective contracts while returns to human capital and the gender wage gap are reduced moreover during the 1990s these effects became stronger

the decline of labour market institutions and the rise in wage inequality in britain abstract at the same time as the role of labour market institutions declined very dramatically in britain there was a very sharp rise in wage inequality that since 1980 has increased at a faster pace than in most advanced countries britain in the 1980s and early 1990s therefore provides a very good testing ground for evaluating the importance of labour market institutions in explaining the evolution of the wage structure i look at this in terms of two institutions that have traditionally propped up wage levels at the bottom end of the wage distribution unions and minimum wages i find that their weakening has played an important part in the rise in wage inequality in britain

analyzing the extent and influence of occupational licensing on the labor market this study examines occupational licensing in the united states using a specially designed national labor force survey estimates from the survey indicated that 35 of employees were either licensed or certified by the government and that 29 were licensed another 3 stated that all who worked in their job would eventually be required to be certified or licensed bringing the total that are or eventually must be licensed or certified by government to 38 we find that licensing is associated with about 18 higher wages but that the effect of governmental certification on pay is much smaller

labor market signaling and self confidence wage compression and the gender pay gap i extend spence s signaling model by assuming that some workers are overconfident they underestimate their marginal cost of acquiring education and some are underconfident firms cannot observe workers productive abilities and beliefs but know the fractions of high ability overconfident and underconfident workers i find that biased beliefs lower the wage spread and compress the wages of unbiased workers i show that gender differences in self confidence can contribute to the gender pay gap if education raises productivity men are overconfident and women underconfident then women will on average earn less than men finally i show that biased beliefs can improve welfare

choices and the value of natural capital sustainability requires maintaining opportunities for future generations so they can meet their needs opportunities are passed to future generations through a set of capital assets nature provides an important class of these assets but markets seldom reveal the marginal value of natural capital rather the marginal social worth or asset price must be imputed based on intertemporal exchange in the context of assessing whether intertemporal allocation rules lead to sustainable development appropriate asset prices must be based on the actual allocations and trade offs society makes therefore measuring economic programmes that enable the measurement of asset prices is an important empirical task we review the theory of measuring natural capital asset prices and discuss the key elements of measuring economic programmes that enable the measurement of natural capital asset prices we place the measurement of economic programmes and natural capital asset prices in the context of wealth based sustainability metrics
