utility rebates for energy star appliances are they effective we estimate the impact of utility cash rebates on the market share of energy star appliances by exploiting the variation in timing and size of rebates across us states we find that a dollar increase in the population weighted utility rebate raises the share of energy star qualified clothes washers by 0 4 but does not affect dishwasher and refrigerator shares using information on energy saved by an energy star appliance and assuming a redemption rate of 40 the cost per tonne of carbon saved is about 140 for the clothes washers rebate program the corresponding cost of a megawatt hour saved about 28 is lower than the estimated cost of building and operating an additional power plant and the average on peak spot price we conclude that the energy star clothes washers rebate program is on average a cost effective way for utilities to reduce electricity demand

the transition to the knowledge economy labor market institutions and income inequality in advanced democracies the transition from fordism to the knowledge economy in the world s advanced democracies was underpinned by the revolution in information and communications technology ict the introduction and rapid diffusion of ict pushed up wages for college educated workers with complementary skills and allowed top managers and ceos to reap greater rewards for their own talents despite these common pressures income inequality did not rise to the same extent everywhere income in the anglo saxon countries remains particularly unequally distributed to shed new light on this puzzle the authors carry out a panel data analysis of eighteen oecd countries between 1970 and 2007 their analysis stands apart from the existing empirical literature by taking a comparative perspective the article examines the extent to which the relationship between the knowledge economy and income inequality is influenced by national labor market institutions the authors find that the expansion of knowledge employment is positively associated with both the 90 10 wage ratio and the income share of the top 1 percent but that these effects are mitigated by the presence of strong labor market institutions such as coordinated wage bargaining strict employment protection legislation high union density and high collective bargaining coverage the authors provide robust evidence against the argument that industrial relations systems are no longer important safeguards of wage solidarity in the knowledge economy

rationality and deterrence this essay explores the relationship between deterrence theory and two distinct notions of rationality associated with it the author argues that the concept of procedural irrationality which is the basis of many critiques of contemporary deterrence theory is not necessarily inconsistent with the instrumental definition of rationality implicit in many models of deterrence he also argues that some recent rational choice models of deterrence are nonetheless deficient in their application of the rationality postulate finally he provides an outline of a possible resolution of the paradox of deterrence

a spatial model of international conflict 1 he model presented here assumes that nations initiate conflict to change the international status quo across one or more issues to an outcome they prefer their preferences for different issue outcomes are represented by a classical spatial utility function international coalitions are formed both to enhance the chance of a successful challenge and to counter existing challenges disputes are modeled as periods of competition between two coalitions through the recruitment of additional members erosion of support for the opposing coalition and escalation of the crisis the two nation model is analyzed in detail and the existence of the core for the resulting game is proved the two main conclusions of the two nation model are that nations have a general incentive to exaggerate their issue positions in disputes and that the possibility of issue trades enhances the likelihood of compromise because scientific understanding arises from theories the explication of theories is essential for the development of scientific understanding to understand international conflictthat is the resolution of disputes between nations by coercion or the threat of coercion a theory that can explain such conflict is needed this paper will present a model drawn from rational choice theory specifically game theory that explains national actions in conflicts as strategic choices made in order to gain preferred resolutions of the international issues in dispute compared to existing game theory models of international conflict the model presented here provides an explicit description of how each nation s evaluation of the issues in dispute affects its desire to pursue compromise or conflict a more detailed sequence of escalation allowing for the detailed study of escalation strategies and a framework that can explain the timing and extent of third party interventions into ongoing crises

the davis bacon act an appraisal of recent studies the intensified controversy in recent years over the davis bacon act which requires the payment of prevailing wages on federally funded construction projects has resulted in several new studies of the effects of that act this invited paper reviews the evidence presented in these recent studies on several aspects of the act including how davis bacon wage determinations compare to local construction wages as measured by sources other than the act s administrators the effects of lags in the act s data gathering process and the savings that would result from calculating the prevailing rate as the arithmetic mean of local wages instead of the current use of the modal rate in most cases the authors conclude that although the cost studies to date have been faulty in several respects it is reasonably clear that davis bacon is unattractive on grounds of economic efficiency alone the question remains however whether these efficiency costs are offset partially or wholly by the possible equity benefits o

skill biased technological change and rising wage inequality some problems and puzzles the recent rise in wage inequality is usually attributed to skill biased technical change sbtc associated with new computer technologies we review the evidence for this hypothesis focusing on the implications of sbtc for overall wage inequality and for changes in wage differentials between groups a key problem for the sbtc hypothesis is that wage inequality stabilized in the 1990s despite continuing advances in computer technology sbtc also fails to explain the evolution of other dimensions of wage inequality including the gender and racial wage gaps and the age gradient in the return to education

the effect of unions on the structure of wages a longitudinal analysis this paper studies the effects of unions on the structure of wages using an estimation technique that explicitly accounts for misclassification errors in reported union status and potential correlations between union status and unobserved productivity the econometric model is estimated separately for five skill groups using a large panel data set formed from the u s current population survey the results suggest that unions raise wages more for workers with lower levels of observed skills in addition the patterns of selection bias differ by skill group among workers with lower levels of observed skill unionized workers are positively selected whereas union workers are negatively selected from among those with higher levels of observed skill despite a large and sophisticated literature there is still substantial disagreement over the extent to which differences in the structure of wages between union and nonunion workers represent an effect of trade unions rather than a consequence of the nonrandom selection of unionized workers over the past decade several alternative approaches have been developed to control for unobserved heterogeneity between union and nonunion workers 2 one method that has been successfully applied in other areas of applied microeconometrics is the use of longitudinal data to measure the wage gains or losses of workers who change union status unfortunately longitudinal estimators are highly sensitive to measurement error even a small fraction of misclassified union status changes can lead to significant biases if the true rate of mobility between union and nonunion jobs is low this sensitivity led lewis 1986 to essentially dismiss the longitudinal evidence in his landmark survey of union wage effects in this paper i present some new evidence on the union wage effect based on a longitudinal estimator that explicitly accounts for misclassification errors in reported union status the estimator uses external information on union status misclassification rates along with the reduced form coefficients from a multi variate regression of wages on the observed sequence of union status indicators to isolate the causal effect of unions from any selection biases introduced by a correlation between union status and the permanent component of unobserved wage heterogeneity recognizing that unions may raise wages more or less for

a life course trajectory framework for understanding the intracohort pattern of wage inequality much research has been devoted to cross sectional and intercohort patterns of wage inequality but relatively little is known about the mechanisms for the intracohort pattern of wage inequality to fill this intellectual gap this article establishes a life course trajectory lct framework for understanding the intracohort pattern of wage inequality first the author proposes and conceptualizes three essential properties of the lct framework random variability trajectory heterogeneity and cumulative advantage that are used to establish a mathematical formalization of the lct framework both the conceptualization and the formalization imply that intracohort wage inequality will increase over the life course due to random variability trajectory heterogeneity and cumulative advantage finally the author combines the lct framework with the multilevel growth curve model then applies the model to data from the nlsy79 and finds support for the significance of random variability trajectory heterogenei

risky business the decline of defined benefit pensions and firms shifting of risk since the early 1980s employment in the united states has undergone significant transformation as the large corporations that once safeguarded employees with stable jobs and rewards for loyalty have replaced these employment relationships with ones based on cost containment and flexibility one important consequence of these developments is that firms have abdicated their role as a critical risk bearer in society although evidence suggests that firms have increasingly shifted market risks onto their workforce to date there have been few detailed analyses exploring what factors have driven this phenomenon this study adds to our understanding of why firms have transferred risk to their employees by examining the decline of a highly institutionalized practice wherein large u s firms used to bear retirement risk the defined benefit db pension plan through a detailed analysis i show that variance in the presence power and interests of shareholders and employees at the firm level differentially affect a firm s willingness to shift the risk of retirement onto its workers specifically i demonstrate empirically that different types of shareholders have differential effects on a firm s retirement practices suggesting that the changing equity ownership structure of large u s firms has played a key role in how risk is allocated between workers and firms declines in employee power have also played a role because firm levels of unionization positively affect rates of db participation for both unionized and nonunionized workers

the expected utility theory of conflict measuring theoretical progress we examine the progressivity of bruce bueno de mesquita s theory of conflict as originally developed in the war trap and as extended later bueno de mesquita offers the progressivity of the expected utility theory relative to other theories and approaches to conflict as his major defense in responding to critics bueno de mesquita essentially relies on imre lakatos definition of theoretical progress in presenting his argument a review of the literature addressing the concept of theoretical progress indicates that bueno de mesquita s application of lakatosian criteria is incomplete and that lakatos criteria are themselves flawed we review the philosophy of science literature dealing with theoretical progress or rational criteria for theory choice and evaluate the progressivity of the expected utility theory of conflict in light of criteria other than lakatos while we do recommend further elaboration of bueno de mesquita s theory we do not find it more progressive than its rivals

technology invention and diffusion in residential energy consumption a stochastic frontier approach traditional large appliances absorb a large share of residential electricity consumption and represent important targets of energy policy strategies aimed at achieving energy security despite being characterized by rather mature technologies this group of appliances still offers large potential in terms of efficiency gains due to their pervasive diffusion in this paper we analyse the electricity consumption of a set of four traditional white goods in a panel of ten eu countries observed over 21 years 1990 2010 with the aim of disentangling the amount of technical efficiency from the overall energy saving the technical efficiency trend is modelled through a set of technology components representing both the invention and adoption process by the means of specific patents weighted by production and bilateral import flows which allows to overcome the rigid stochastic frontier framework in modelling the effect of technical change our results show that the derived energy demand and inefficiency trends are both related to changes in the amount of available technology embodied in energy efficient appliances the effect is significant both in its domestic and international components and suggests an active role of innovation and trade policies for achieving efficiency targets which directly impact the amount of electricity consumed by households

general deterrence between enduring rivals testing three competing models general deterrence unlike immediate deterrence has rarely been analyzed in a systematic comparative manner we outline a research design for doing so by studying the circumstances under which in a set of enduring rivalries challengers are likely to initiate militarized disputes we indicate the conceptual and operational steps necessary to make and empirically compare predictions stemming from three often competing theoretical frameworks rational deterrence a general model of rational conflict initiation and a cognitive psychological model of behavior emphasizing risk orientation and misperception the results of probit analysis on a pooled time series of enduring rivalries since 1945 provide support for hypotheses from each of the different theoretical models

what happened to long term employment the role of worker power and environmental turbulence in explaining declines in worker tenure recent declines in the average length of time that u s workers spend with a given employer represent an important change in the nature of the employment relationship yet it is one whose causes are poorly understood i explore those causes using current population survey data on the tenure of men aged 30 65 from the years 1979 2008 i argue that long term employment relationships primarily occur when workers pressure employers to close off employment from market competition reducing the attractiveness of external mobility relative to internal opportunities and increasing employment security i then explore how two changes in organizations environments a decline in union strength and increased turbulence from changes in technology and globalization might have affected workers ability to secure such closed employment relationships over the last 30 years my results support the argument that declines in tenure reflect the reduced power of workers to secure closed employment relationships recent declines in tenure have been concentrated in large organizations and many of those declines are explained by controlling for the changing levels of industry unionization i find little evidence that foreign competition or technological change affected mobility the results are robust to measures of changing industry growth rates and within industry reorganization supplementary analyses suggest that layoffs are associated with different industry pressures than tenure and that voluntary mobility may have played an important role in declines in tenure

immigration and inequality immigration is often viewed as a proximate cause of the rising wage gap between highand low skilled workers nevertheless there is controversy over the appropriate theoretical and empirical framework for measuring the presumed effect and over the precise magnitudes involved this paper offers an overview and synthesis of existing knowledge on the relationship between immigration and inequality focusing on evidence from cross city comparisons in the u s while some researchers have claimed that a cross city research design is inherently flawed i argue that the evidence from cross city comparisons is remarkably consistent with recent findings based on aggregate time series data in particular cross city and aggregate time series comparisons provide support for three key conclusions 1 workers with below high school education are perfect substitutes for those with a high school education 2 high school equivalent and college equivalent workers are imperfect substitutes with an elasticity of substitution on the order of 2 3 within education groups immigrants and natives are imperfect substitutes together these results imply that the average impacts of recent immigrant inflows on the relative wages of u s natives are small the effects on overall wage inequality including natives and immigrants are larger reflecting the concentration of immigrants in the tails of the skill distribution and higher residual inequality among immigrants than natives even so immigration accounts for a small share 5 of the increase in u s wage inequality between 1980 and 2000

collective labor rights and income inequality this article examines the relationship between income inequality and collective labor rights conceptualized as workers legal and practical ability to engage in collective activity although worker organization is central to explaining income inequality in industrialized democracies worldwide comparative studies have neglected the role of class based actors i argue that the repression of labor rights reduces the capacity of worker organizations to effectively challenge income inequality through market and political processes in capitalist societies labor rights however are unlikely to have uniform effects across regions this study uses unbalanced panel data for 100 developed and less developed countries from 1985 through 2002 random and fixed effects models find that strong labor rights are tightly linked to lower inequality across a large range of countries including in the global south interactions between regions and labor rights suggest that the broader context in which class based actors a

quality over quantity reexamining the link between entrepreneurship and job creation although much has been written about the quantity of jobs created by entrepreneurs scholars have yet to examine the quality of these jobs in this article the authors begin to address this important issue by examining nearly 5 000 businesses that began operations in 2004 they investigate the extent to which nascent employers provide what many think of as quality jobs those offering health care coverage and a retirement plan the authors find that because of small scale constrained resources and protection from institutional pressures start up companies do not provide their employees with either of these proxies for job quality and their likelihood of offering health or retirement benefits increases only marginally over their first six years of operation the finding that entrepreneurs impressive record of job creation is not matched by a similarly impressive outcome with respect to job quality challenges policymakers to ensure that entrepreneurs are encouraged to create quality employment opportunities in the course of creating new businesses abstract from author

nonunion wage rates and the threat of unionization i investigate how the threat of union organization affects the wage paid to nonunion workers i start by outlining the standard model of wage determination by a nonunion employer when faced with the threat of union organization the model suggests that the nonunion wage will be directly related and the union wage gap will be inversely related to the threat i use repeated cross section data from the cps from 1977 2002 to develop a measure of the threat as the predicted probability of union membership i use this measure to estimate earnings functions that use several sources of variation in the likelihood of union membership to identify the threat effect in a manner that reduces the likelihood of omitted variable bias finally i investigate two cases where there has arguably been a change in the likelihood of union organization that is not correlated with changes in the demand for labor these include the wage changes surrounding the introduction of rightto work rtw laws in two states during the period studied and wage changes surrounding deregulation of key industries in the late 1970s and early 1980s the results are mixed the preferred estimates from the analysis using predicted probability of unionization as the threat measure imply very little relationship between either nonunion wages or the union wage gap and the threat the estimates that rely on the introduction of rtw laws show a significant relationship between nonunion wages and the introduction of rtw laws in one of the two states stronger evidence of threat effects is found in the experience of deregulated industries where regulation was a central factor in union strength

job queues and the union status of workers this paper develops a model of the determination of the union status of workers that allows for the possibility of queuing for union jobs the empirical results derived using a sample from the university of michigan panel study of income dynamics are supportive of the queuing hypothesis the no queue model can be rejected using a likelihood ratio test this suggests that a simple probit or logit model for union status is misspecified because it is not based on any consistent behavioral theory an important implication of the model is that because most new entrants to the labor market prefer union jobs but cannot get them and because accrual of nonunion seniority makes workers progressively less likely to desire union jobs the union status of workers is largely determined by their success in being selected from the queue early in their working life

union strength neoliberalism and inequality contingent political analyses of u s income differences since 1950 do historically contingent political accounts help explain the growth in family income inequality in the united states we use time series regressions based on 60 years to detect such relationships

financialization and u s income inequality 1970 2008 focusing on u s nonfinance industries we examine the connection between financialization and rising income inequality we argue that the increasing reliance on earnings realized through financial channels decoupled the generation of surplus from production strengthening owners and elite workers negotiating power relative to other workers the result was an incremental exclusion of the general workforce from revenue generating and compensation setting processes using time series cross section data at the industry level we find that increasing dependence on financial income in the long run is associated with reducing labor s share of income increasing top executives share of compensation and increasing earnings dispersion among workers net of conventional explanations such as deunionization globalization technological change and capital investment the effects of financialization on all three dimensions of income inequality are substantial our counterfactual analysis suggests that financial

union effects on nonunion wages evidence from panel data on industries and cities the authors test for threat and crowding effects of unions on non union wages at the industry and city levels using panel data on the percent organized and nonunion industry and city wage differentials constructed from current population surveys over the period 1973 89 at the industry level increases in the percent organized were associated with decreases in the nonunion industry wage differential suggesting that crowding effects were the predominant union effect on nonunion industry wage differentials in contrast at the city level increases in the percent organized were associated with increases in the nonunion city wage differential suggesting that threat effects predominated the authors also find evidence of negative cross occupation union effects on nonunion industry wage differentials supporting their hypothesis that the industry level results were partly driven by complementarity between union and nonunion labor

is energy efficiency capitalized into home prices evidence from three u s cities abstract we test for evidence that energy efficiency features are capitalized into home prices in three u s metropolitan areas using hedonic regressions and multiple matching procedures we find that energy star certification is associated with higher sales prices in two of the markets the research triangle region of north carolina and portland oregon we find that local green certifications in portland and in austin texas are also associated with higher prices and that the estimated price impacts are larger than those from energy star matching on observables proves to be important in some cases reducing the estimated impacts compared with models without matching we calculate the implied energy savings from the estimated premiums and find that in the research triangle market the energy star premiums approximately equal the savings that program is designed to achieve but in portland the premiums are slightly greater than the program s savings due to low energy costs in the region

making the implicit explicit a look inside the implicit discount rate implicit discount rates idrs are employed in energy models to capture household investment decisions yet the factors behind the idr and their respective implications for policy making usually remain blurred and fractional the proposed comprehensive framework distinguishes three broad categories of factors underlying the idr for household adoption of energy efficient technologies eets preferences notably over time risk loss debt and the environment predictable ir rational behavior bounded rationality rational inattention behavioral biases and external barriers to energy efficiency existing empirical findings suggest that the factors underlying the idrs that differ across household characteristics and technologies should be accounted for in energy models furthermore the framework allows for a fresh look at the interplay of idrs and policies we argue that a simple observation of high idrs or observing correlations between idrs and socio economic characteristics does not provide guidance for policy making since the underlying sources cannot be identified instead we propose that some of the factors underlying the idr notably external barriers can be changed through directed policy interventions whereas other factors notably preferences and predictable ir rational behavior are innate and can only be taken into account through reactive policy interventions

designing incentive schemes for promoting energy efficient appliances a new methodology and a case study for spain the energy efficiency gap has been high on research and policy agendas for several decades incentive schemes such as subsidies taxes and bonus malus schemes are widely used to promote energy efficient appliances most research however considers instruments in isolation and only rarely in the context of political constraints on instrument use or for alternative policy goals this paper presents a methodology for the optimal design of incentive schemes based on the minimisation of dead weight loss for different policy goals and policy restrictions the use of the methodology is illustrated by designing optimal combinations of taxes and subsidies in spain for three types of appliance dishwashers refrigerators and washing machines the optimal policies are designed subject to different policy goals such as achieving a fixed reduction in emissions or a certain increased market share for efficient appliances and for policy constraints such as budget neutrality the methodology developed here can also be used to evaluate past and current incentive schemes

the politics of union decline the contingent determinants of union recognition elections and victories despite the close political regulation of union recognition disputes sociologists have paid little attention to recent political determinants of success in these contests a state centered political opportunity approach suggests that if conservative political officials can reduce the number of union recognition elections union organization will be blocked partly because many labor scholars claim there was a postwar departure in labor movement fortunes we attempt to detect and model a contingent break in the relationship between republican control of the presidency and these elections using interactive specifications our findings show that shortly after the conservative anti union reagan administration took office recognition elections and union victories in these elections fell sharply with macroeconomic and other determinants held constant other political conditions with explanatory power include congressional oversight committee ideology and conservative appointments to the key regulatory age

exploring the role of households hurdle rates and demand elasticities in meeting danish energy savings target abstract the eu s energy efficiency directive eed sets a binding target for energy savings in eu member states the eed further requires member states to perform ex ante evaluations of energy efficiency policies implemented to achieve these savings however ex ante evaluation of energy efficiency policies is difficult as it requires detailed modelling of end users investment and energy demand behaviour this paper details the danish interact modelling approach for ex ante evaluation of energy efficiency policies directed at residential heating interact integrates the energy system model times dk into a computable general equilibrium framework the paper explores the potential for meeting denmark s eed target through a policy induced increase in households investments in energy efficiency retrofits the paper considers the effect of energy efficiency policies on households investment behaviour by applying different levels of hurdle rates on households investments in energy efficiency retrofits the paper shows that reducing the hurdle rate from 25 to 4 could meet more than a third of danish energy saving requirements for the period 2021 2030 this result includes a direct rebound effect of 31 finally the paper demonstrates that reducing the hurdle below 10 has a substantial negative impact on households disposable income making such policy less viable from a policy perspective

income inequality in the united states 1913 1998 this paper presents new homogeneous series on top shares of income and wages from 1913 to 1998 in the united states using individual tax returns data top income and wages shares display a u shaped pattern over the century our series suggest that the large shocks that capital owners experienced during the great depression and world war ii have had a permanent effect on top capital incomes we argue that steep progressive income and estate taxation may have prevented large fortunes from fully recovering from these shocks top wage shares were flat before world war ii dropped precipitously during the war and did not start to recover before the late 1960s but are now higher than before world war ii as a result the working rich have replaced the rentiers at the top of the income distribution

what makes deterrence work cases from 1900 to 1980 the use of military force to achieve foreign policy objectives is an enduring feature of international politics force or the threat of force may be used either to change the status quo or to maintain it threatening the use of force to maintain the status quo often takes the form of deterrence defined by patrick morgan as the threat to use force in response as a way of preventing the first use of force by someone else 1 deterrence sometimes succeeds and sometimes fails failures are attested to by numerous international wars of history in the nuclear age a failure could cost us our lives the conditions of successful deterrence thus require thorough logical and empirical analysis

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

efficiency effectiveness and implementation feasibility of energy efficiency rebates the renove plan in spain abstract state sponsored incentive policies frequently include subsidies or rebates for the purchase of more efficient appliances however more research is required into the effects of this tool in isolation a case in point is the so called renove plan in spain first the inefficiency losses dead weight losses associated with energy efficiency rebates must be taken into account such a policy may also encourage the large scale purchasing of energy efficient appliances which may finally result in an increase in electricity consumption rebound effect furthermore although a subsidy is more widely accepted than other tools from social and political viewpoints especially than taxes the fiscal consolidation challenge faced by many countries reduces the scope for environmental policy measures on the expenditure side of the budget and strengthens the need to use taxes to meet the agreed policy objectives this paper shows that the current application of the spanish renove plan with rebates on the dishwasher market for energy efficient appliances generates some welfare losses a rebound effect and a considerable deficit in public budgets the paper examines and assesses the effect of different combinations of taxes and rebates in the case of dishwashers in spain based on their performance in terms of economic efficiency environmental effectiveness and implementation feasibility

design in context existing international agreements and new cooperation this research note highlights an important element missing from rational design theories of international agreements institutional context the presence or absence of existing and prior agreements between prospective partners in new cooperation if as rational design theorists argue agreement design is deliberate strategic and directed toward enhancing contracting parties ability to credibly commit to future cooperation then prior design successes should influence the terms of additional cooperation we test for this omitted variable problem in three agreement design outcomes ex ante limitations on agreement duration exit clauses and dispute settlement provisions through an augmentation and reanalysis of data from a key study in the rational design literature barbara koremenos s contracting around international uncertainty we show institutional context is positively correlated with inclusion of ex ante time limitations in negotiated agreements and negatively correlated with the inclusion of exit clauses and third party dispute settlement provisions institutional context also mediates and conditions the effects of the explanatory variable at the heart of existing rational design theories uncertainty about the future distribution of gains from cooperation our findings show that the collective appeal of particular design features varies not only with the nature of underlying strategic problems but also with degrees of shared institutional context

unions norms and the rise in u s wage inequality from 1973 to 2007 private sector union membership in the united states declined from 34 to 8 percent for men and from 16 to 6 percent for women during this period inequality in hourly wages increased by over 40 percent we report a decomposition relating rising inequality to the union wage distribution s shrinking weight we argue that unions helped institutionalize norms of equity reducing the dispersion of nonunion wages in highly unionized regions and industries accounting for unions effect on union and nonunion wages suggests that the decline of organized labor explains a fifth to a third of the growth in inequality an effect comparable to the growing stratification of wages by education

the war trap revisited a revised expected utility model the expected utility framework developed in the war trap is revised to correct several deficiencies risk taking orientations are now treated as an integral part of the model by introducing concavity or convexity into the utility functions the zero sum properties of the theory are largely eliminated and the tendency toward interpersonal comparisons of utility is removed several earlier results are replicated with the new model and with annual capabilities data new propositions are deduced that identify important limitations on conflict initiation and relationships resulting from differences in perceptions are tested support is found for the contention that the revised version of the theory of which the original model is a special case is a powerful tool for integrating many extant hypotheses about conflict and for explaining a substantial portion of the tendency for some threats to escalate to violence or warfare and for others to be resolved peacefully

estimating the effects of consumer incentive programs on domestic automobile sales we investigate the effects of consumer sales promotion on automobile sales the largest dollar volume durable goods category in retailing between 1985 and 1987 the domestic automakers offered major year end promotions on automobiles using low rate financing and cash rebates to stimulate sales this article uses time series techniques to evaluate the sales patterns for general motors ford and chrysler between 1983 and 1987 explicitly estimating the effects of the incentive programs the analysis indicates that the 1985 and 1986 promotional campaigns were quite successful but that the 1987 campaign was largely ineffective the 1986 and 1987 promotions were also followed by large post promotion drops in sales the analysis contains two notable findings that are in contrast with the considerable body of empirical evidence about the effects of promotion on nondurable goods

this job is getting old measuring changes in job opportunities using occupational age structure high and low wage occupations are expanding rapidly relative to middle wage occupations in both the u s and the e u we study the reallocation of workers from middle skill occupations towards the tails of the occupational skill distribution by analyzing changes in age structure within and across occupations because occupations typically expand by hiring young workers and contract by curtailing such hiring we posit that growing occupations will get younger while shrinking occupations will get old after verifying this proposition we apply this observation to local labor markets in the u s to test whether markets that were specialized in middle skilled occupations in 1980 saw a differential movement of both older and younger workers into occupations at the tails of the skill distribution over the subsequent 25 years consistent with aggregate trends employment in initially middle skill intensive labor markets hollowed out between 1980 and 2005 employment losses among non college workers in the middle of the occupational skill distribution were almost entirely countered by employment growth in lower tail occupations for college workers employment losses at the middle were offset in roughly equal measures by gains in the upper and lower tails of the occupational skill distribution but gains at the upper tail were almost entirely limited to young college workers consequently older college workers are increasingly found in lower skill lower paying occupations this abstract was borrowed from another version of this item

the escalation of great power militarized disputes testing rational deterrence theory and structural realism realism we test the relative explanatory power of these two theoretical approaches on the escalation of deterrence encounters among great powers from 1816 to 1984 we derive a set of hypotheses from each model operationalize them for systematic empirical analysis and test the hypotheses on 97 cases of great power deterrence encounters by means of probit analysis the results are that the hypotheses derived from deterrence theory receive considerable support whereas none of the hypotheses derived from structural realism are supported in contemporary research on the causes of international conflict the realist paradigm has been the dominant theoretical approach within this broad framework however scholars have developed at least two prominent alternative models of the conditions under which conflict is likely to arise the first approach structural realism 1 focuses on the attributes of the international system while the second deterrence theory is largely dyadic and emphasizes the resolve and relative military capabilities of adversarial states while both theoretical approaches attempt to identify the conditions under which international crises and wars are likely to arise their

estimating the effects of unions on wage inequality in a panel data model with comparative advantage and nonrandom selection this article considers the estimation of the structure of wages in union and nonunion sectors it proposes an estimator that extends standard panel data techniques to the case in which the return to the permanent component of the error term is differently rewarded in the two sectors the econometric model is used to estimate the effect of unions on both the level and the variance of wages in canada the findings indicate that unions increase the average wage of workers and compress the returns to observable measures of skill and to a time invariant unobservable measure of skill

the effect of unions on wage inequality in the u s labor market this study uses current population survey micro data for 1973 74 and 1993 to evaluate the effect of changing union membership on trends in male and female wage inequality unionization rates of men fell between the two sample periods with bigger declines among lower skill groups these trends account for 15 20 of the rise in male wage inequality union membership rates of low wage women also declined while unionization increased among higher wage women on balance shifting unionization accounts for very little of the rise in female wage inequality economy wide trends in unionization mask a sharp divergence between the private sector where unionism was declining and the public sector where it was rising comparisons across sectors suggest that unionization substantially slowed the growth in wage inequality in the public sector

union membership union organization and the dispersion of wages a variance components model explains wage dispersion with a specific version of generalized least squares the estimation preserves individual data while examining the influence of union penetration on dispersion in both the union and nonunion sectors controlling for both individual and industry characteristics and for the endogeneity of wages union penetration correlates strongly with reduced dispersion in the union sector but not in the nonunion sector a decomposition reveals the relative importance of the influences of union penetration and of union membership copyright 1990 by mit press

stratification by regulation are bootleggers and baptists biased this paper investigates whether and to what extent regulation may be associated with wage inequality using regulation measures created by al ubaydli and mclaughlin regul govern 11 109 123 2017 i find that regulation is associated with larger within occupation wage inequality specifically i show that a worker at the 90th wage percentile realizes a raise of 1 19 per hour relative to the 10th percentile earner for each standard deviation increase in regulation that represents a 3 5 raise for a worker at the 90th percentile overall increases in the regulatory burden are associated with 42 45 of the change in the 90th 10th percentile wage ratio from 2002 through 2014

durable goods and residential demand for energy and water evidence from a field trial this article describes a household production model in which energy efficient durable goods cost less to operate so households may use them more the model is estimated using household level data from a field trial in which participants received high efficiency clothes washers free of charge the estimation strategy exploits this quasi random replacement of washers to derive precise estimates of the household production technology and a demand function for clothes washing during the field trial households increased clothes washing on average by 5 6 after receiving a high efficiency washer implying a price elasticity of 06 the complete model is used to evaluate the cost effectiveness of recent changes in minimum efficiency standards for clothes washers

public sector earnings and the extent of unionization many studies have examined the influence of union density union members as a percentage of all workers on earnings in the private sector but few such studies have looked at the public sector using data from the 1991 current population survey this study estimates the determinants of earnings for state and local government employees in both the union and nonunion sectors the extent of public sector unionization appears to be positively correlated with earnings for both state and local government workers and for those covered and not covered by collective agreements although the effect for non covered employees is smaller than that for covered employees both effects are larger than those typically found in similar estimates for the private sector the authors also find that bargaining structure has some influence on earnings with the most consistent effect being a positive influence of arbitration on the earnings of local government workers

the political economy of minimum wage legislation two questions are addressed in this paper a why do labor unions and certain employer organizations respectively promote and impede minimum wage legislation b do these groups have significant impacts on minimum wages question a is examined in the context of models that identify the economic self interest of unionized skilled workers and capitalists in legal wage floors question b is approached by a median legislator utility maximization model that leads to tobit estimation of the relationship between state minimum wage rates and measures of statewide organized labor and capital and average hourly earnings

tax incidence with endogenous quality and costly bargaining theory and evidence from hybrid vehicle subsidies abstract endogenous quality and bargaining are important features of many markets but are typically omitted from studies of incidence we develop a model with product upgrades and costly bargaining and find that tax rate pass through only partially characterizes the welfare impact of taxation consumers may respond to a tax or subsidy by changing product quality or by changing their bargaining effort we apply the insights of our theory to the study of subsidies for green goods specifically hybrid electric vehicles in canada we utilize highly detailed transaction data and leverage panel variation in subsidies across provinces for identification our baseline estimate finds that prices rises by 570 for every 1000 increase in the subsidy but this pass through estimate substantially underestimates consumer gains because a majority of this price increase 459 80 is due to increased product quality in the form of additional options and features

on the estimation of union threat effects some researchers view unions primarily as functioning to increase earnings inequality among the working class while others see them as threatening employers so that they raise wages for unorganized workers and minimize working class inequality threat effects are defined as the tendency for nonunionized employers to respond to the threat of unionization by increasing the earnings and benefits of their workers this paper probes a contextual method for estimating the effects of unionization on the earnings of unorganized workers this method controls for structural characteristics that affect workers earnings and incorporates information about the organizational strength and vitality of specific unions using data from seven manufacturing industries in indianapolis the results suggest that 1 unionized workers earnings positively affect the earnings of unorganized workers in unionized plants 2 unionized workers earnings negatively affect nonunionized workers earnings in nonunionized plants and 3 when plant size is controlled unionized workers earnings have no significant effect on the earnings of nonunionized workers in nonunionized plants these results highlight the complexity and difficulty of estimating the effects of union threat and their importance for understanding earnings inequality in the workplace

do energy prices influence investment in energy efficiency evidence from energy star appliances abstract i examine whether electricity prices influence the likelihood that consumers purchase high efficiency appliances by using state year panel data on electricity prices and the proportion of sales of new appliances that involve high efficiency energy star models i find no evidence that electricity prices affect the propensity for consumers to choose high efficiency appliances point estimates are extremely small and precisely estimated the findings suggest that price based energy policies may be limited in the extent to which they increase investment in residential energy efficiency which has been considered one of the lowest cost opportunities for reducing carbon emissions

occupations and the structure of wage inequality in the united states 1980s to 2000s occupations are central to the stratification systems of industrial countries but they have played little role in empirical attempts to explain the well documented increase in wage inequality that occurred in the united states in the 1980s and 1990s we address this deficiency by assessing occupation level effects on wage inequality using data from the current population survey for 1983 through 2008 we model the mean and variance of wages for each occupation controlling for education and demographic factors at the individual level to test three competing explanations for the increase in wage inequality 1 the growth of between occupation polarization 2 changes in education and labor force composition and 3 residual inequality unaccounted for by occupations and demographic characteristics after correcting for a problem with imputed data that biased kim and sakamoto s 2008 results we find that between occupation changes explain 66 percent of the increase in wage inequality from 1992 to 2008

sluggish institutions in a dynamic world can unions and industrial competition coexist during the 1930s and 1940s collective bargaining emerged as the workplace governance norm in much of the u s industrial sector following its peak in the 1950s union density in the u s private sector fell steadily to only 7 4 percent in 2006 governance shifted from a formalized union norm to one of constrained managerial discretion in competitive and dynamic economic environments a union tax on company earnings and slow response to economic shocks combine to produce poor performance by union companies two industries automotives and airlines are used to illustrate these points if worker based institutions are to flourish they must add value and permit companies to perform at levels similar to those obtained under evolving nonunion governance norms

the payoff to skill in the third industrial revolution1 is the third industrial revolution indeed driven by rising payoffs to skill this simple but important question has gone unanswered because conventional models of earnings inequality are based on exceedingly weak measurements of skill by attaching occupational skill measurements to the 1979 2010 current population surveys it becomes possible to adjudicate competing accounts of the changing returns to cognitive creative technical and social skill the well known increase in between occupation inequality is fully explained when such skills are taken into account while returns to schooling prove to be quite stable once correlated changes in workplace skills are parsed out the most important trend however is a precipitous increase in the wage payoff to synthesis critical thinking and related analytic skills the payoff to technical and creative skills often touted in discussions of the third industrial revolution is shown to be less substantial

performance pay and wage inequality an increasing fraction of jobs in the u s labor market explicitly pay workers for their performance using bonus pay commissions or piece rate contracts using data from the panel study of income dynamics we show that compensation in performance pay jobs is more closely tied to both observed and unobserved productive characteristics of workers than compensation in non performance pay jobs we also find that the return to these productive characteristics increased faster over time in performance pay than in non performance pay jobs we show that this finding is consistent with the view that underlying changes in returns to skill due for instance to technological change induce more firms to offer performance pay contracts and result in more wage inequality among workers who are paid for performance thus performance pay provides a channel through which underlying changes in returns to skill get translated into higher wage inequality we conclude that this channel accounts for 21 of the growth in the variance of male wages between the late 1970s and the early 1990s and for most of the increase in wage inequality above the eightieth percentile over the same period

contraction and expansion the divergence of private sector and public sector unionism in the united states the institutional structure of the american labor market changed remarkably from the 1950s and 1960s to the 1980s in the 50s and 60s trade unions seemed permanently established in the private sector of the economy a third of nonagricultur al wage and salary workers and over half of blue collar workers were union members hundreds of thousands of workers voted annually in national labor relations board nlrb representation elections to join unions most large firms sought stable collective bargaining relations with their unions by contrast in the public sector only 10 12 percent of workers were union members fewer were covered by collective bargaining contracts and most experts regarded public employees as intrinsically nonorganizable according to afl cio president george meany it was impossible to bargain collectively with the government kramer 1962 p 14 the massive contraction of unionism in the private sector and expansion in the public sector in the 1970s and 1980s see exhibit 1 has produced an utterly different situation today in the private sector the proportion of wage and salary workers in unions plummeted to 14 percent in 1986 a level comparable to that in the great depression only a minuscule number of workers joined unions through nlrb elections and national companies openly proclaimed their intent to establish a union free environment by contrast in the public sector over a third of the work force was unionized some 40 percent were covered by collective contracts 1 and 1 estimates of organization in the public sector differ somewhat among sources though all data show greater organization than in the private sector see freeman ichniowski and zax forthcoming for a detailed analysis of the various statistics

skill biased technological change and wage inequality evidence from a plant retooling1 one of the most popular explanations for the increased wage inequality that has occurred since the late 1970s is that technological change has resulted in a downward shift in the demand for low skill workers this pattern is also alleged to account for the growth in racial inequality in wages over the same period this article reports on a case study of the retooling of a food processing plant a unique longitudinal multimethod design reveals the nature of the technological change the changes in job requirements and the mechanisms by which the changes affect the wage distribution for hourly production workers this research finds that indeed the retooling resulted in greater wage dispersion and that the changes have also been associated with greater racial inequality in wages however contrary to the claims of advocates of the skill bias hypothesis organizational and human resources factors strongly mediated the impact of the changing technology absent these high road organizational choices th

nonmarital first births marriage and income inequality many aggregate level studies suggest a relationship between economic inequality and socio demographic outcomes such as family formation health and mortality but individual level evidence is lacking nor is there satisfactory evidence on the mechanisms by which inequality may have an effect we study the determinants of transitions to a nonmarital first birth as a single parent or as a cohabiting parent compared to transitions to marriage prior to a first birth among unmarried childless young adults in the national longitudinal survey of youth 1997 cohort from 1997 to 2011 we include measures of county group level household income inequality and of the availability of jobs typically held by high school graduates and which pay above poverty wages we find that greater income inequality is associated with a reduced likelihood of transitioning to marriage prior to a first birth for both women and men the association between levels of inequality and transitions to marriage can be partially accounted for by the availability of jobs of the type we measured some models also suggest that greater income inequality is associated with a reduced likelihood of transitioning to a first birth while cohabiting

the costs of war a rational expectations approach a model of war costs is presented that is based on the utility nations expect to derive from the war as well as on the technological gap between adversaries and the short term tactical tit for tat calculations that must occur on the battlefield this model explains nearly three quarters of the variance in battle deaths per million population per month of war experienced by war initiators approximately one quarter of the variance in war costs is accounted for by considering the position of the initiator s opponent a second model based on marginal changes in expected utility technological differences and tit for tat is shown to account for more than one third the variance regardless of whether war costs are viewed by the initiator or an opponent in a war this study therefore provides a useful explanation of war intensity and contributes to the cumulative lawlike implications of the expected utility approach on which it is based

the american jobs crisis and its implication for the future of employment policy a call for a new jobs compact the author proposes a new jobs compact to close the nation s jobs deficit to create sufficient high quality jobs to raise wages and end thirty years of wage stagnation and to update and strengthen labor and employment policies a set of market and institutional failures are identified as root causes of these problems and local innovations and policy proposals are suggested for overcoming them achieving these objectives will require a stronger voice in national policymaking as well as proactive efforts to mobilize and coordinate the constituencies that share an interest in and responsibility for employment policy and practice the author calls on the president and the secretary of labor to lead these efforts by mobilizing and engaging business labor women ethnic community and education leaders at regional and national levels

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

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

match bias in wage gap estimates due to earnings imputation about 30 of workers in the current population survey have earnings imputed wage gap estimates are biased toward zero when the attribute being studied e g union status is not a criterion used to match donors to nonrespondents an expression for match bias is derived in which attenuation equals the sum of match error rates attenuation can be approximated by the proportion with imputed earnings union wage gap estimates with match bias removed are presented for 1973 2001 estimates for recent years are biased downward 5 percentage points bias in gap estimates accompanying other non match criteria public sector industry etc is examined

growing apart the changing firm size wage premium and its inequality consequences wage inequality in the united states has risen dramatically over the past few decades prompting scholars to develop a number of theoretical accounts for the upward trend this study argues that large firms have been a prominent labor market institution that mitigates inequality by compensating their low and middle wage employees with a greater premium than their higher wage counterparts large u s firms reduced overall wage dispersion yet broader changes to employment relations associated with the demise of internal labor markets and the emergence of alternative employment arrangements have undermined large firms role as an equalizing institution using data from the current population survey and the survey of income and program participation we find that in 1989 although all private sector workers benefited from a firm size wage premium the premium was significantly higher for individuals at the lower end and middle of the wage distribution compared to those at the higher end between 1989 and

the rise of finance and firm employment dynamics this article sheds light on the ongoing employment stagnation in the united states by investigating the links between the rise of finance and firm employment dynamics during the 1982 2005 period i argue that the rise of finance marginalized the role of labor in revenue generating and sharing processes which led to employment stagnation among the largest nonfinancial firms in the united states evidence suggests that increasing investment in financial assets depresses the workforce size the growing dependence on debt reprioritizes the order of distribution heightening the need for workforce reduction the increasing rewards for shareholders generate a downsize and distribute spiral in which labor expense becomes a primary target of cost cutting strategies further analysis indicates that production and service workers are more vulnerable to shifts associated with the rise of finance than managers and professionals

workplace compensation practices and the rise in benefit inequality this article aims to explain why inequality in fringe benefits has grown faster than wage inequality over the past four decades we depart from previous income inequality research by studying benef
