wage determination in brazil the growth of union bargaining power and informal employment this article examines wage determination in brazilian manufacturing during the 1980s and early 1990s it presents evidence to show that the reduction in state regulation of collective bargaining has led to the development of a system of wage determination which is increasingly characterised by rent sharing and insider trade union bargaining power real wages appear increasingly inflexible with respect to movements in open unemployment with a large informal sector disciplining formal sector wage bargaining and cushioning the impact of broader labour market conditions an important consequence of this is that the employment costs of a successful counter inflationary strategy may be very severe

two stage bargaining with coverage extension in a dual labour market abstract this paper studies coverage extension in a simple general equilibrium model with a dual labour market the union sector is characterized by two stage bargaining whereas the firms set wages in the non union sector in this model firms and unions of the union sector have a commonality of interest in extending coverage of a minimum wage to the non union sector furthermore the union sector does not seek to increase the non union wage to a level above the market clearing wage in fact it is optimal for the union sector to impose a market clearing wage on the non union sector finally coverage extension increases welfare in this model

the low skill trap recently it has become popular to argue that certain workers have fallen into a trap in which they have poor skills few job opportunities and a low return on training while others have not this paper demonstrates how such a trap can occur within a simple matching model with rent sharing rent sharing diminishes the worker s incentive to acquire skills however since firms also benefit from training rent sharing likewise induces job creation the subsequent improved matching prospects may offset the initial disincentive to invest however for this mechanism to be effective firms and workers must coordinate their actions if they do not the trap occurs

profit sharing capital formation and the nairu this paper reconsiders the impact of different remuneration systems on aggregate employment contrary to common wisdom on this topic we show that the switch from a fixed wage economy to a share economy results in lower aggregate unemployment an additional innovation of this paper is the endogeneity of the capital stock decision of the firm which enables us to assess and reject the common disincentive to invest criticism of a share economy

efficiency wages and local wage bargaining in the literature on wage drift it is often argued that strikes or work to rule practices are used to force employers to pay a wage rate that exceeds the contract wage here we introduce the efficiency wage argument as a foundation for bargaining about wage drift contrary to the view in most bargaining models where firms and unions struggle to divide a fixed pie given employment we take the relation between wages and revenues explicitly into account the implications for wages and employment appear to differ not only with respect to the order of magnitude but also in a qualitative sense

a non radial dea approach to measuring environmental performance data envelopment analysis dea has gained great popularity in environmental performance measurement because it can provide a synthetic standardized environmental performance index when pollutants are suitably incorporated into the traditional dea framework past studies about the application of dea to environmental performance measurement often follow the concept of radial efficiency measures in this paper we present a non radial dea approach to measuring environmental performance which consists of a non radial dea based model for multilateral environmental performance comparisons and a non radial malmquist environmental performance index for modeling the change of environmental performance over time a case study of oecd countries using the proposed non radial dea approach is also presented it is found that the environmental performance of oecd countries as a whole has been improved from 1995 to 1997

regional disparities in the unemployment rate the role of the wage setting mechanism in spain 1987 92 bande r fernandez m and montuenga v m 2007 regional disparities in the unemployment rate the role of the wage setting mechanism in spain 1987 92 regional studies 41 the aim of this paper is to show how regional unemployment disparities in spain widen during economic upturns and to provide an explanation of this behaviour the analysis is based on the study of the wage setting mechanism that allows an estimation of the responses of wages to both labour productivity and the general situation of the labour market and an assessment of their impact on the evolution of regional unemployment the results of this estimation at the regional level with manufacturing data confirm the existence of marked differences between industries and between regions these responses these differences can be interpreted as a distinctive wage setting mechanism across industries and regions which may explain the evolution of unemployment rates within the regional labour markets bande r fernandez m et montuenga v

what does tax aggressiveness signal evidence from stock price reactions to news about tax shelter involvement abstract we study the stock price reaction to news about corporate tax aggressiveness we find that on average a company s stock price declines when there is news about its involvement in tax shelters we find some limited evidence for cross sectional variation in the reaction for example the reaction is more negative for firms in the retail sector suggesting that part of the reaction may be a consumer taxpayer backlash in addition the reaction is less negative for firms that are viewed to be generally less tax aggressive as proxied by the firm s cash effective tax rate we interpret this as being consistent with the market reacting positively to evidence that a firm is trying to reduce taxes when their financial reports would lead one to believe the firm is not tax aggressive

a new theory of corporatism and wage setting abstract the standard view on corporatist institutions for wage setting in many european economies is based of the insider outsider model corporatism is associated with lack of wage flexibility this paper discusses a new approach starting from the importance of nominal contracts the rationale for these contracts is to avoid future bargaining adjusting these contracts ex post to aggregate shocks would raise their efficiency however avoiding the bargaining required for this adjustment was the main reason for negotiating these contracts in the first place this is the fundamental contradiction under corporatism outside institutions can play this role these institutions provide therefore a type of flexibility not available in decentralized economies empirical evidence supports the basic ideas of this model

imperfectly competitive labour markets and the productivity puzzle abstract we integrate imperfectly competitive labour markets in a dynamic macromodel in accordance with empirical evidence we find that temporary shocks are consistent with little real wage and large employment responsiveness while permanent shocks affect real wages and not employment

efficiency wages and industry wage differentials a comparison across methods of pay efficiency wage considerations should be less important for piece rate pay than for time wages therefore if industry wage differentials reflect efficiency wage factors then these pay differences should be less sizable and have less explanatory power for piecework than for timework we test this proposition using wage data for male production workers employed in the swedish metalworking industries in 1985 the data are partitioned into two groups of workers in our preferred sub sample of workers who received pay under both piece rates and time wages our results are uniformly consistent with efficiency wage implications for industry wage differentials for the subsample of workers who received pay under either piece rates or time wages industry wage differentials are of equal importance under either pay scheme these latter results however may also be influenced by unaccounted for sorting of workers and employers across methods of pay overall our examination of industry wage differentials across m

corporate social responsibility theories mapping the territory the corporate social responsibility csr field presents not only a landscape of theories but also a proliferation of approaches which are controversial complex and unclear this article tries to clarify the sit uation mapping the territory by classifying the main csr theories and related approaches in four groups 1 instrumental theories in which the corporation is seen as only an instrument for wealth creation and its social activities are only a means to achieve economic results 2 political theories which concern themselves with the power of corporations in society and a responsible use of this power in the political arena 3 integrative theories in which the corporation is focused on the satisfaction of social demands and 4 ethical theories based on ethical responsibilities of corporations to society in practice each csr theory presents four dimensions related to profits political performance social demands and ethical values the findings suggest the necessity to develop a new theory on the business and society relationship which should integrate these four dimensions

work sharing employment and wages the paper analyzes the effects of a reduction in working time on wages and employment with a monopoly union in general it is not clear in which directions these variables move but if employment and working time are perfect substitutes the effects are related to how working time has been determined initially the wage increases if initial working time is smaller than or equal to the trade union optimum whereas the result is unclear when it is larger in this case it is never optimal for a trade union to reduce both the wage and working time in response to a recessionary supply shock the analysis may help to explain varying attitudes towards work sharing in different countries

carbon emissions performance in logistics at the city level the importance of good performance in the logistics industry contributing towards a low carbon economy is widely recognised however there are few studies on carbon emissions performance for the logistics industry especially at the city level therefore this study attempts to analyse the carbon emissions performance of the logistics industry at the city level by examining sixteen cities within yunnan province in particular the data envelopment analysis dea model and malmquist index from both the static and dynamic perspective were explored to further capture the driving factors of the carbon emissions performance in logistics the tobit model was applied to perform regression analysis the results indicate that 1 with regards to static performance two northwest cities nujiang and diqing have reached the technological frontier 2 regarding dynamic performance although six cities have improved the average dynamic logistics carbon emissions performance of all the cities decreases by approximately 5 9 from 2011 to 2015 3 in terms of driving factors the economic development factor is found to be positively and significantly related to static carbon emissions performance whereas others indicate negative and significant relationships

efficient energy saving targets for apec economies abstract energy saving target ratios estr for 17 apec economies during 1991 2000 are computed in a total factor framework all nominal variables are transformed into real variables by the purchasing power parity ppp at the 1995 price level the data envelopment analysis dea approach is used to find the energy saving target est for apec economies without reducing their maximum potential gross domestic productions gdps in each year energy labor and capital are the three inputs while gdp is the single output our major findings are as follows 1 china has the largest est up to almost half of its current usage 2 hong kong the philippines and the united states have the highest energy efficiency 3 the energy efficiency generally increases for apec economies except for canada and new zealand 4 chile mexico and taiwan have significantly improved their energy efficiency in the last 5 years 5 an inverted u shape relation exists between per capita est and per capita gdp 6 estr has a positive relation with the value added percentage of gdp of the industry sector and a negative relation with that of the service sector

corporate tax avoidance and firm value abstract do corporate tax avoidance activities advance shareholder interests this paper tests alternative theories of corporate tax avoidance using unexplained differences between income reported to capital markets and to tax authorities ols estimates indicate that the effect of tax avoidance on firm value is a function of firm governance as predicted by an agency perspective on corporate tax avoidance instrumental variables estimates based on exogenous changes in tax regulations yield larger overall effects and reinforce the basic result as do several robustness checks the results suggest that the simple view of corporate tax avoidance as a transfer of resources from the state to shareholders is incomplete given the agency problems characterizing shareholder manager relations

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

modeling undesirable factors in efficiency evaluation abstract data envelopment analysis dea measures the relative efficiency of decision making units dmus with multiple performance factors which are grouped into outputs and inputs once the efficient frontier is determined inefficient dmus can improve their performance to reach the efficient frontier by either increasing their current output levels or decreasing their current input levels however both desirable good and undesirable bad factors may be present for example if inefficiency exists in production processes where final products are manufactured with a production of wastes and pollutants the outputs of wastes and pollutants are undesirable and should be reduced to improve the performance using the classification invariance property we show that the standard dea model can be used to improve the performance via increasing the desirable outputs and decreasing the undesirable outputs the method can also be applied to situations when some inputs need to be increased to improve the performance the linearity and convexity of dea are preserved through our proposal

multilateral productivity comparisons when some outputs are undesirable a nonparametric approach multilateral productivity comparisons of firms producing multiple outputs some of which are undesirable are obtained by making two modifications to the standard farrell approach to efficiency measurement the restriction that production technology satisfy strong disposability of outputs is relaxed to allow for the fact that undesirable outputs may be freely disposable and the efficiency measures are modified to allow for an asymmetric treatment of desirable and undesirable outputs performance measures that satisfy these requirements are calculated as solutions to programming problems the methodology is applied to a sample of mills producing paper and pollutants

measuring energy use and co2 emission performances for apec economies abstract this study proposes environmental dea based models to measure energy use efficiency co2 emissions efficiency and an environmental economic efficiency eee for the asia pacific economic cooperation apec economies for the period of 2006 2010 in our models population and total primary energy consumption are the two inputs while gdp and co2 emissions represent the desirable and undesirable outputs respectively empirical results from 20 apec economies showed that australia brunei hong kong and singapore were identified as efficient countries for five consecutive years from 2006 to 2010 in terms of energy use efficiency as for co2 emission efficiency brunei hong kong and singapore were identified as efficient countries for the five consecutive years from 2006 to 2010 as far as eee is concerned most countries in apec exhibited higher economic efficiency than environmental efficiency moreover both energy use efficiency and co2 emission efficiency were found to be significantly related to the eee value p

unions and interindustry wage differentials abstract we investigate the importance of trade unions in collective bargaining in the context of a developing country manufacturing labor market the methodology we adopt to estimate wage differentials follows the method proposed by haisken denew j p and schmidt c m 1997 review of economics and statistics 79 516 521 since it improves on the standard procedure popularized by krueger a b and summers l h 1988 econometrica 56 193 259 our findings indicate that wage dispersion is far greater in the unionized sector of brazilian manufacturing in contrast to evidence from other countries

the determination of wages employment and work hours in an economy with centralised wage setting sweden 1950 83 a key component of recent explanations for the growth in unemployme nt in western europe is a negative relation between wage rates and employment this paper examines the evidence for such a relationship for swedish manufacturing industry and also investigates the corresponding movements of hours of work the findings form the ingredients of a structural model of the labor market which is estimated using time series observations from 1951 t o 1983 the greater volatility of employment relative to earnings is measured by a specific parameter which in this model relates to the objectives of trade unions copyright 1988 by royal economic society

insider forces and wage determination this paper investigates the relative importance of firm specific factors i e insider forces in wage determination using firm level data on 219 u k companies over 1974 82 it finds that a 1 percent rise in a firm s prices or productivity relative to the aggregate economy leads to a rise in relative wages of 0 1 0 2 percent as a corollary to this outside factors like the aggregate wage and the unemployment rate also play an important role there is evidence for insider based hysteresis effects but these are inversely related to the extent to which firms take national agreements into account copyright 1990 by royal economic society

estimating the linkage between energy efficiency and productivity abstract many analyses have referred to industrial productivity benefits associated with energy efficiency that are at least as great or larger than the energy benefits if plants with higher energy intensity also tend to have lower productivity then energy policy needs to consider this this study examines this issue for two segments of the glass industry using plant level data from the census bureau productivity is defined by the difference in best practice production efficiency as measured by data envelopment analysis dea this study uses regression analysis to estimate how differences in plant level electricity and fossil fuel intensity i e energy use per unit of production are attributable to differences in plant level productivity and other economic variables like energy prices and cumulative production in every case productivity differences between plants are statistically significant in explaining differences in plant energy intensity the coefficient that links productivity to energy efficiency yields a less than proportional impact for only one industry and fuel type for others the relationship is implies that a 1 increase in productivity increase energy efficiency by more than 1 this effect is statistically significant for flat glass but not container glass the estimates of the price and learning by doing coefficients seem reasonable but without imposing the assumption that all plants in the industry are equally productive this lends further credence to a significant relationship between productivity and energy efficiency

wage drift and the relevance of centralised wage setting the system of wage setting in the nordic countries is often regarded as highly centralised contributing to considerable real wage flexibility this view has been questioned as sizeable wage drift may offset the effect of central negotiations this paper presents evidence from the four major nordic countries suggesting that there is little or no such offsetting effect yet at central negotiations the institutional system of wage formation may induce nominal rigidities that may prevent wage restraint when there is little room for money wage growth empirical evidence supports the existence of nominal rigidity

consumer reactions to corporate tax strategies effects on corporate reputation and purchasing behavior on the basis of an interdisciplinary approach linking taxation marketing and corporate social responsibility the present research investigates the effects of media reports on aggressive and responsible corporate tax strategies ctss on corporate success with consumers by means of two laboratory experiments n 150 360 we analyze the effects of the ctss on corporate reputation consumer purchase intention and the consumer s willingness to pay our results suggest that aggressive ctss diminish corporate success with consumers whereas responsible ctss enhance it nevertheless consumers are not willing to pay a price premium for products sold by responsible tax planning companies but rather punish aggressive tax planning companies through a slightly lower willingness to pay finally consumers tax morale and their attitude toward tax avoidance are important moderating variables given the growing level of media interest in taxation our findings are crucial for assessing consumer related non tax costs and the benefits of different ctss

the rise in unemployment a multi country study one of the most remarkable features of recent economic history has been the remorseless rise in unemployment throughout the industrialized countries however while the trend to higher unemployment is universal the experience of individual countries also differs widely the increase is especially marked within the european community where unemployment rates rival those reached in the interwar years by contrast in the scandinavian countries and japan unemployment is lower and has risen very much less experience in the united states lies somewhere between these extremes and in the last few years unemployment there has fallen sharply

local and central wage bargaining the literature on wage bargaining usually considers either central or local wage bargaining an exception is holmlund 1986 throughout most of the unionized part of the private sector in norway wage bargaining takes place on two levels first centrally and then locally in the economic policy debate it has been argued that this system leads to higher wages and lower employment than bargaining on only one level regardless of whether it is central or local see e g skatnland 1983 in this paper i present a model with wage bargaining on two levels and show that in this system the above argument is proved false we focus on an industry with n identical firms which produce one homogeneous product for simplicity the output price and input prices other than wages are considered given on the central level there is a utility maximizing labor union with a quasi concave utility function increasing in the arguments employment l and total wage vv there is a local labor union in each firm we analyze the system during one period say a year wage setting in this period consists of three stages in the first stage the central labor union sets the tariff wage q unilaterally this follows the monopoly model of e g dunlop 1944 and oswald 1985 in the second stage the firms determine the employment l which prevails until the next period in the third and final stage the local union negotiates with the management of the firm about local wage drift the total wage is w q wage drift the assumption that the firms determine employment prior to wage bargaining is used by e g moene 1987 and horn wolinsky 1985 both the central labor union and the firms know how local wage bargaining functions and can therefore perfectly anticipate what the result

insider effects in wage determination abstract the paper attempts to shed new light on the determinants of industry wages by a cross country comparison of wage setting relationships making use of comprehensive and consistent panel data on industries from the early 1960s to the mid 1980s the empirical analysis involves estimations of identically specified industry wage equations for each of five countries sweden norway finland germany and the united states a key finding is that industry wages in the u s are the most responsive to sectoral price and productivity changes by contrast industry wages in the nordic countries are largely unaffected by sectoral conditions the results cast doubt on the competitive model as an accurate characterization of wage setting under decentralization

central wage setting under multiple technological equilibria a mechanism for equilibrium elimination instituting an initial round of centralized wage setting before an ultimate round of decentralized wage bargaining may actually raise employment a general multi equilibrium model is set up with strategic complementarities in the implementation of a new technology through aggregate demand spillovers in this model centralized wage setting to establish an outside option wage which is selectively binding on lo tech firms may achieve the big push to a hi tech general equilibrium with higher employment output wages and profits

the incremental information content of replacement cost earnings abstract the study explores the incremental explanatory power of replacement cost earnings variables derived from asr 190 data with respect to explaining cross sectional differences in security returns as such the study is a natural extension of previous research including analyses of the effect of security returns of asr 190 data at the time of disclosure investigations of cross sectional relationships between security returns and historical cost earnings and studies of multiple signals the basic finding is that pre holding gain net income provides no incremental explanatory powerm given knowledge of historical cost earnings however the converse does not hold taken together the findings are consistent with the contention that pre holding gain net income is a garbled version of historical cost earnings the basic finding is robust under several extensions of the initial research design the research design incorporates a two stage approach which permits a determination of the incremental explanatory power of collinear variables the findings are in contrast to those of a previous study by easman et al 1979 the nature of the difference in research design inducing the difference is identified potential reasons for the difference in findings are provided

efficiency wages and local versus central wage bargaining abstract a simple efficiency wage model is extended to allow for the presence of unions the presence of unions aggravates the unemployment caused by efficiency wage considerations provided the labour demand elasticity is not too much larger than one local firm level wage bargaining gives a higher negotiated wage than central wage bargaining implying higher unemployment under local wage bargaining than under central wage bargaining

tax avoidance as a sustainability problem this manuscript proposes that tax avoidance can be better understood and mitigated as a sustainability problem tax avoidance is not just a financial problem for tax authorities but one that erodes critical common spaces necessary for the smooth functioning of regulatory compliance organizational integrity and society defining tax avoidance as a sustainability problem offers a broader and more holistic understanding of the organizational and societal consequences of tax avoidance behavior sustainability is also a mature and legitimized concept that can readily incorporate taxation a variety of established sustainability metrics have the capacity to incorporate anti tax avoidance measures or publicize firms that engage in fair tax practices this manuscript concludes that integrating sustainability principles in conjunction with important extant work on corporate social responsibility and taxation can advance the goals of decreasing the occurrence and acceptability of tax avoidance

aggressive tax avoidance by managers of multinational companies as a violation of their moral duty to obey the law a kantian rationale managers of multinational companies often favour an aggressive tax avoidance strategy that pushes the legal limits onto the advantage of shareholders and the disadvantage of the spirit of democratically legitimized tax laws the public and media debate whether such aggressive behaviour is immoral aggressive tax avoidance is a subset of the aggressive legal interpretations potentially observable in all fields which places little weight on the will of a democratically legitimized legislation a thorough ethical analysis based on the deontological approach of kant demonstrates that aggressive tax avoidance as a special case of operating on the edge of legal boundaries is potentially immoral applying the kantian contradiction of conception or will test shows that this maxim might not be conceived or willed as a general law of nature if all natural or legal persons aggressively interpret laws on all subjects and in every imaginable situation then central principles of the system of law we all rely upon would be severely compromised therefore aggressive tax avoidance by managers of multinational companies may violate the managers moral duty to obey not only the letter but also the intention or spirit of the law the validity of the argumentation depends critically on the formulation and interpretation of the respective maxims and on assumptions about the legal system preserving central elements of kantian philosophy the article demonstrates the complexity of a philosophical argumentation which tries to justify the moral intuitions that underpin the common negative evaluation of aggressive legal strategies in business

wages policy and unemployment in australia it is generally accepted among australian economists that high rates of growth of wages at various times over the last decade have made the achievement of full employment and lower rates of inflation more difficult fear of a further acceleration of wage growth has also been a policy constraint it is when one attempts to go further that considerable disagreement becomes evident from a labour market viewpoint there does not seem to be a consensus as to the answers to the two broad questions that should be addressed first how important are wage changes relative to other factors that depress employment and add to the inflation rate second how does government policy impinge on the process that generates wage changes to do justice to both of these in a paper as short as this one is difficult so i shall focus most of the paper on the second question the relationships between government policy and wage changes are particularly important at this time for most of the last decade successive governments have operated a national wages policy which to a large degree has been based on the indexation of wages for past price changes the latest experiment the prices and incomes accord is the centrepiece of the current government s employment and inflation policy and after almost two years of wide community and media support the key principles upon which it is based are suddenly being questioned 1 our prime endeavour therefore will be to build up sufficient understanding of the wage determination process so that some evaluation can be made as to the effectiveness of these national wage policies this turns out to be a remarkably difficult task which generates considerable concern in our mind that the data may not be sufficiently rich to serve as a basis for sound judgments it does appear however that the effect of a given level of unemployment upon wage changes has consistently weakened over the last decade why this should be so is a major unresolved puzzle i offer a loosely constructed theory that is consistent with the facts but it is by no means the only possible explanation section i provides a description of wage setting in australia and some key facts of the economy in section ii the statistical analysis of wage changes focuses on two competing theories one is the phillips curve approach and the other stresses that wage outcomes may be to a significant degree independent of the level of unemployment and may depend instead on utilization rates of labour within the firm section iii considers the efficacy of incomes policies in australia some final comments areoffered in section iv

slacks based efficiency measures for modeling environmental performance we develop two slacks based efficiency measures for modeling environmental performance on the basis of environmental dea technology of the two measures one is a composite index with a higher discriminating power for modeling economic environmental performance and the other can be used to estimate the impacts of environmental regulations we apply the proposed measures to model the co2 emissions of 30 oecd countries from 1998 to 2002 and present the results obtained

an investigation into the power of insiders in wage determination abstract this paper is concerned with the role of insider forces in wage determination various union and non union models of wage behaviour are considered and they imply that wages are a convex combination of internal and external factors certain union models also imply a degree of hysteresis data on fourteen british production industries reveal that i insider forces are important ii their importance is directly related to both union power and the degree of monopoly in the product market iii the state of the aggregate labour market is also important and iv hysteresis effects arising from insider power are only significant in a small minority of sectors
