unions relative wages and economic efficiency the ability of unions to raise the wages of their members above the wages of similar but nonunionized workers is well documented this paper examines empirically the implications of that wage differential for resource allocation and economic efficiency this is accomplished by explicitly solving a numerically specified general equilibrium system with and without the wage differential comparison of the two solutions yields the desired information the findings indicate that the wage premium results in adjustments in prices and quantities of factors and commodities that vary widely across industries these adjustments are found to carry a small deadweight loss as measured by the hicksian equivalent variation

unions in a general equilibrium model of firm formation unions are introduced into a general equilibrium model of firm formation i find under reasonable conditions that large firms are more likely to be unionized and that unionized firms are more productive and better managed than nonunion firms of the same size as well unions reduce economic efficiency by distorting the occupation choice decision between managing a firm and working in one perhaps surprisingly this distortion persists even when individual union contracts set both wages and employment in a fully efficient manner but can disappear when the mechanism that allocates property rights to union jobs is changed in certain ways

markets hierarchies and information on a paradox in the economics of organization abstract the literature on the economics of organization presents the following paradox on the one hand firms are said to be repositories of superior information about input characteristics on the other hand markets are said to be superior to hierarchies in coordinating resource allocation because hierarchies are forced to aggregate heterogeneous inputs into homogeneous categories this paper suggests reasons for the association of firms with refined input information and argues that it is not their hierarchical features but their provision of an appropriate framework for rent sharing that is responsible for this association

union retreat and regional economic performance the uk experience monastiriotis v 2007 union retreat and regional economic performance the uk experience regional studies 41 1 14 a panel of regional data is used to investigate the impact the well documented decline in trade unionism in the uk had on the economic performance of its regions the analysis departs from the traditional firm level and cross sectional analyses and looks at the economy wide effects of unionism the findings provide evidence in line with theory that predicts that unions will increase wages and unemployment but they also indicate that unionism is positively related to productivity and incomes although in all cases the effects are non linear it is concluded that unionism is not necessarily a burden for the economy so long that the beneficial wage productivity effects outweigh the negative effects on employment monastiriotis v 2007 le declin syndical et la performance economique regionale etude de cas du r u regional studies 41 1 14 on emploie des donnees regionales provenant d un

unions and strikes with asymmetric information strikes seem to be a pareto inefficient outcome of bargaining between a union and a firm however this paper shows that strikes can be the outcome of rational behavior by both agents if the firm has more information than the union concerning the state of nature the union can use strikes as a way of gaining information the paper uses an asymmetric information model where the firm has information about the state i e profitability that the union does not know the schedule of wage offers by the union then depends on the probability that a given state will occur

estimating uk regional price indices 1974 96 hayes p 2005 estimating uk regional price indices 1974 96 regional studies 39 333 344 this paper examines the behaviour and construction of regional expenditure indices published in the croner reward regional cost of living surveys for 1974 96 it identifies a number of problems in using these data as an appropriate deflator to the new earnings survey regional wages series in examining labour supply side decisions instead an alternative method with which to construct regional prices is recommended using a combination of data from croner reward from the published retail price index rpi and from the expenditure and food survey efs formerly known as the family expenditure survey whilst these new data suggest that regional inflation rates were not significantly different from one another over the sample period they point to an episode of increased regional price variation over the late 1980s and early 1990s this paper suggests that these alternative indices would be of interest when examin

strategic work interactions and the kibbutz kolkhoz paradox the authors develop a model of strategic work interactions in collective enterprises explaining the following observation the israeli kibbutz in which net collective output is distributed equally has been an economic success while the soviet kolkhoz in which net output traditionally was divided according to relative work input has been a failure in contrast the conventional cournot nash theory of collective enterprises predicts superoptimal output in the kolkhoz while in the kibbutz the free fider problem is predicted to lead to suboptimal effort their theory predicts pareto optimal work effort in the kibbutz and suboptimal effort in the kolkhoz copyright 1989 by royal economic society

the effects of unions on organisational change and employment this paper investigates the association between unionism organizational change and employment using british data over 1980 84 union plants were more likely to have experienced organizational change this is likely to be due to both the once for all removal of restrictive practices and union voice effects the oft cited negative relationship between unionism and employment growth may well arise from the differential extent to which restrictive practices were removed in union plants during 1980 84 more importantly the authors present evidence suggesting that unions were associated with faster employment growth during the late 1970s copyright 1991 by royal economic society

on pollution permits and abatement abstract we construct a dynamic general equilibrium model of pollution and study in a holistic way the environmental policies whereby government sets up emission caps and sells emission permits at a competitive price which can be viewed as an emission tax then it uses the collected tax revenues to finance public abatement activities we characterize a steady state equilibrium and show how it changes with the size of the economy and with a change in natural pollution absorption rate

shirking and the choice of technology a theory of production inefficiency with an empirical application abstract we develop a model of shirking and technology choice and show that organizations exercising less effective direct control over shirking adopt technologies that underutilize the workforce to a greater degree relative to neoclassical counterparts in order to control shirking indirectly thus technical inefficiency arises endogenously as a rational response to allocative inefficiency caused by shirking an empirical analysis of data from a sample of collective and private farms operating in jewish palestine reveals the presence of shirking and supports the prediction that farms with less effective direct control over shirking exhibit greater labor hoarding as a manifestation of technical inefficiency

unions wages and productivity some evidence from uk engineering firms estimates of union wage and productivity effects are derived using primary micro level panel data for a sample of firms in the uk engineering industry union wage differentials of the order of 10 are suggested from the results whereas union productivity impacts appear to be non linear with respect to union density

third world debt and its effects on the british economy a southern view of economic mismanagement in the north when citicorp one of the largest banks in the world announced its decision to make a us 3 billion provision against third world loans in may 1987 almost every commentator agreed that it represented a turning point in the debt crisis it marked the end of the major banks policy of turning a blind eye to the debt crisis after years of unrealistic projections false hopes and promises in the north and with a third world debt already well above us 1 000 billion the banks suddenly began to speak of debt realities see for instance morgan guaranty s world financial markets june july 1987 this realism was a pre condition for overcoming one of the main stumbling blocks to any solution of the crisis namely the reluctance of the main creditor banks to acknowledge the impossibility of recovering the full face value of their ldcs loans

a solution to the problem of externalities when agents are well informed the author describes a class of simple two stage mechanisms that implement efficient allocations as subgame perfect equilibria for economic environments involving externalities these mechanisms known as compensation mechanisms solve a wide variety of externalities problems including implementation of lindahl allocations regulation of monopoly and efficient solutions to the prisoner s dilemma copyright 1994 by american economic association

nirvana efficiency a comparative test of residual claims and routines two widely adopted views of firm efficiency are agency theorists residual claims and organization theorists routines the agency view holds that ownership structures and their proxies are the primary source of efficiency differences between firms the organization theory view holds that organizational routines are the primary source of efficiency differences between firms we conduct an empirical test that compares the relative value of residual claims and routines in generating firm efficiency while controlling other factors we find support for both views but more importantly find that the average value of routines is roughly an order of magnitude higher than residual claims 1999 elsevier science b v all rights reserved jel classification l 2

trade unions and employment change an analysis of british establishment data few explanations of the changing employment structures of industrialised countries have omitted some reference to the role of trade unions for some commentators it is the unions ability to raise wages above their natural market level that constitutes a brake on employment growth by increasing the employer s costs and making product prices uncompetitive for others it is the unions power to impose uneconomic working practices upon management that leads to decline or lack of growth of the organisation for a discussion see freeman and medoff 1984 mayhew 1983 empirical testing of these and other lines of explanation has been hampered in britain by lack of suitable datasets while employment data are detailed and widely available systematic and reliable information on the extent of trade union influence has been restricted to reported membership levels for broad industry groups see for example bain and price 1983 pencavel 1974 the coverage of collective bargaining derived from earnings surveys see for example mulvey 1976 layard metcalf and nickel1 1978 and the extent and frequency of strike action see for example smith et al 1978 j the availability of a new series of nationally representative surveys at the establishment level has enabled us to obtain new insights into the relationship between changes in employment and trade union organisation at the point where such relationships arguably occur the place of work the

behavior of the firm under regulatory constraint a recent article by akira takayama discusses an earlier paper by harvey averch and leland l johnson on fair rate of return regulation of public utilities although takayama p 255 agrees with averch and johnson s general conclusions that a firm will tend to increase its investment with the introduction of an active constraint on its rate of return he criticizes the a j argument as being confusing ambiguous and in error takayama then attempts a clarification and presents a new formulation which leads to the a j result quoted above this comment will discuss several of takayama s criticisms in addition to showing that the so called a j effect cannot be derived from the basic assumptions made by both averch and johnson and takayama 1 we will show that the very assumptions used to prove the a j effect by defining the region of x require an assumption that the a j effect exists in the first place

wages rents and the quality of life this study focuses on the role of wages and rents in allocating workers to locations with various quantities of amenities the theory demonstrates that if the amenity is also productive then the sign of the wage gradient is unclear while the rent gradient is positive the theory is extended to include the housing market and nontraded goods these extensions require little modification of the conclusion the empirical work on wages shows that the regional wage differences can be explained largely by these local attributes with the use of site price data implicit prices are estimated and quality of life rankings for the cities are computed

allocation of pollution abatement under learning by doing abstract this paper examines how learning by doing affects the allocation of pollution abatement between heterogeneous technologies over time the optimal policy balances current abatement costs against reductions in future costs and infant technologies may be preferred to mature technologies despite greater initial costs we characterize when a technological winner might emerge and we identify conditions under which optimal abatement is shared across all technologies pigouvian taxes can implement the first best but may need to be differentiated across technologies when technical change is induced an important role of environmental policies is to put abatement on the right technological trajectories

testing the nairu model for the united states this paper tests using u s data the dynamics implied by the nairu view of the relationship between inflation and the unemployment rate the results are somewhat sensitive to the measure of inflation used but they generally reject the dynamics an alternative way of thinking about the relationship between inflation and the unemployment rate is suggested

market opening regulation and growth in europe deregulation a political economy analysis lack of urgency explains why continental europe trails in the deregulation process yet there are lessons to be learnt from deregulation elsewhere this paper reviews the situation and focuses on the political preconditions for successful deregulation it finds a clear negative relationship between regulation and economic performance it characterizes european countries by the degree of regulation of labour and product markets and finds that the latter seems to be more important for economic performance finally it notes the importance of a proper management of the deregulation effort which may include some re regulation deregulation is more likely to succeed the more transparent the economic benefits and the more clearly stated the objectives and the time schedule kees koedijk and jeroen kremers

effort technology and the efficiency of agricultural cooperatives abstract the inefficiency of cooperative agriculture relative to private farms is often attributed to difficulties in monitoring or poor incentives we develop a model to show that in technologies with numerous sequential steps even small shortfalls in worker effort can result in large output declines using data on cooperative and private farms in el salvador we find greater shortfalls in efficiency between cooperatives and private farms as well as among cooperatives for coffee a crop requiring numerous steps in its cultivation than for maize and sugar which require fewer steps thus the undersupply of effort in cooperatives may be less than differences in productivity suggest and cooperative agriculture is most likely to be successful where production does not involve many sequential steps

are union productivity effects overestimated evidence from coal mining the empirical literature of the influence of unions on productivity is extended by considering the effect in an industry with heterogeneous firms recent theoretical papers suggest that in such an industry unions will tend to organize the exogenously more productive firms thus a spurious correlation between unions and productivity may emerge we test this hypothesis by estimating production functions for coal with data from eastern kentucky underground coal mines the aspect of mine heterogeneity that we focus on is the width of the mine s seam of coal wider seams increase productivity empirically we find that unions disproportionately organize mines with wider seams and this accounts for the positive relationship between unions and productivity observed in our data in fact once seam thickness is accounted for the estimated effect of unions on productivity is negative

unionization and profitability evidence from the capital market this paper examines the effect of unionization on the profitability of firms abnormal monthly common stock returns for a sample of 253 nyse listed firms are estimated for the month in which the union petitions for an election and for the month in which the national labor relations board certifies the election outcome the results suggest that unionization on average is associated with a reduction in equity value when unions win an election the average loss associated with the unionization drive is 3 8 percent of equity value when unions lose an election there is an average net reduction of 1 3 percent in the equity value of the firm

a dynamic analysis of investment in process and product innovation with learning by doing this paper investigates the optimal control problem of a monopolist s investments in process and product innovation under learning by doing in a dynamic setting we show that i there exists the saddle stable steady state under monopolist optimum and social optimum ii the learning rates of product and process innovation affect not only the monopolist s process or product innovation investments but also the complementarity substitutability relationship between product and process innovation iii the social incentive towards both product and process innovation is always larger than the private incentive characterizing the profit seeking monopolist these results are valuable complement and development to the results drawn from the standard product and process innovation model

developing countries changing nature of financial integration and new forms of external vulnerability the brazilian experience this article argues using the example of brazil that the changing nature of developing and emerging countries decs financial integration has created new forms of external vulnerability causing large and volatile capital and exchange rate movements despite sound fundamentals and a substantial reduction in its traditional external vulnerabilities the brazilian real has been one of the most volatile currencies over recent years the article argues that this has been the result of the surging exposure of foreign investors in an increasingly complex set of very short term domestic currency assets following a minskyan analysis we demonstrate that the changing nature of brazil s external vulnerability confirms both the inherent and endogenous instability of international capital flows and decs subordinate role in the international financial system we conclude with policy recommendations to reduce decs external vulnerability sustainably

unions and the capture of economic rents an investigation using british firm level data this paper considers the relationship between unions and profitability in a sample of large british firms in 1984 and 1985 the initial finding is that unionised firms have significantly lower profit margins than otherwise comparable non union firms tests of whether the ability of unions to influence profit margins varies with the product and labour market characteristics of the firms in which they are located are then conducted the ability of unions to capture economic rents is seen to be significantly greater in firms which have a high market share and or operate in highly unionised industries

gone fishing reported sickness absenteeism and the weather i introduction the principal agent problem of contracting employee work effort that is imperfectly monitored arises in a number of areas of economic theory including models of remuneration by seniority lazear 1979 involuntary unemployment e g shapiro and stiglitz 1984 performance based pay macleod and malcomson 1998 and labor hoarding depken redmount and snow 2001 given the importance of this mechanism in the theoretical work the empirical research on the agency problem is remarkably scant in part this reflects the limited availability of personnel data as baker and holmstrom argue in their review article internal labour markets too many theories too few facts 1995 but more fundamentally it reflects the inherent difficulty of empirically capturing the employee effort levels that underlie the models using direct measures of employee or firm level productivity is unquestionably the preferred approach but these measures are notoriously problematic and the studies that use them tend to be case studies introducing external validity issues it is also unlikely to isolate the type of malfeasant shirking behavior that concerns variants of the models where the employee effort decision entails disciplinary risk to inform employee incentives to engage in malfeasant behavior economists have relied on two measures employee disciplinary rates e g cappelli and chauvin 1991 ichino and maggi 2000 and absenteeism rates e g arai and thoursie 2005 bradley green and leeves 2007 ichino and riphahn 2005 the difficulty is that disciplinary rates capture only shirking activity that is identified by employers not that which goes undetected while reported absenteeism particularly sickness absenteeism rates may be entirely legitimate one can therefore never be sure whether differences in these rates across workers facing different shirking costs reflect actual shirking activity as opposed to differences in employers willingness or ability to detect and punish shirkers or differences in employee health that may be correlated with these costs in this paper we identify a different type of shirking activity that potentially addresses both of these shortcomings employees misreporting health in order to exploit weather conditions favorable to high utility outdoor recreation 1 we begin by considering a shirking model of sickness absenteeism in which employees marginal utility of outdoor leisure is increasing in the interaction of two state dependent parameters health and outdoor weather quality the intuition being that ideal weather conditions for engaging in outdoor recreation are valued more when one is physically and perhaps also mentally healthy this assumption leads to two main propositions first increases in sickness absenteeism associated with marginal improvements in weather quality reflect the decisions of the inframarginal workers those workers who in the absence of the weather improvement would be present at work who are the healthiest implying an increase in absenteeism that is unambiguously illegitimate second comparing across workers marginal weather improvements should have the largest impact on sickness absenteeism where shirking costs are highest the reason is that where existing incentives to misreport health are the weakest such as where sick pay is not offered or job protection is weak existing sickness absenteeism levels will be lowest and the inframarginal workers will be the healthiest thereby benefitting most from the weather improvement we examine the empirical relevance of these propositions using a two step approach first we construct an index of weather preferences by linking temperature relative humidity precipitation wind speed and cloud cover data to time use data identifying the weekend and weekday evening outdoor recreational activities of employees with regular daytime work schedules we then examine the empirical relation between the resulting index of the recreational quality of the weather hereafter referred to simply as weather quality and the incidence of short term spells of sickness absenteeism reported in survey data comparing the magnitude of this relation across workers facing different levels of sick pay job protection and job finding rates

three and a half cycles of mania panic and asymmetric crash east asia and latin america compared this paper argues that despite some significant differences the 1982 debt crisis the 1994 mexican crisis and the 1997 east asian crisis share the common characteristic that over lending and over borrowing are basically endogenous market failures of over liquid and under regulated financial markets along the lines described by kindleberger s manias panics and crashes although these crashes have tended to be asymmetric as the largest international lenders have emerged relatively intact the paper concludes with a discussion of brazil s increasing vulnerability to a sudden collapse of confidence and withdrawal of finance which indicates the probability of another impending crisis

union wages temporary lay offs and seniority it is widely believed that the seniority system in conjunction with the collective bargaining process contributes significantly to the determination of the unemployment level in unionized sectors causa i empiricism suggests that real wage demands often remain buoyant in these sectors in the face of seemingly high rates of unemployment among union members james medoff 1979 p 380 convincingly documents the evidence that adjustment through lay offs is substantially greater in unionized firms than in comparable non unionized firms the usual but somewhat informal explanation is that the outcome of union voting is greatly influenced by senior workers who are fairly certain that they will not be laid off when normal shifts in the industry s demand for labour occur 2 these inframarginal workers are believed to vote for higher wage settlements than they would if their own jobs were not so secure

a dynamic general equilibrium model of pollution abatement under learning by doing in 2013 beladi et al constructed a dynamic general equilibrium model of pollution and characterized a steady state equilibrium in this paper we extend beladi et al s model to an even more general model in which the pollution abatement costs under learning by doing are taken into account in our model the instantaneous abatement costs depend on both the rate of abatement and the experience of using a technology our objective is to apply optimal control theory to investigate the dynamic general equilibrium model of pollution abatement and derive the steady state equilibrium properties and optimal levels of emission permits and pollution treatment

heterogeneous firms and the organization of production firms in the same industry exhibit systematic differences in the organization of production and the structure of employment entrepreneurial ability is the specific scarce input that limits the size of a firm this input must be allocated to two activities coordinating production and monitoring workers able entrepreneurs can convert calendar time into larger supplies of coordinating effort that enable them to assemble large firms greater ability implies a higher shadow price of time which increases the implicit costs of monitoring a dispersion of entrepreneurial abilities generates an equilibrium size distribution of firms differences in monitoring costs affect the choice of worker productivities the design of products and the organization of production the monitoring cost hypothesis advanced in this paper goes a long way in explaining the equilibrium of an industry containing heterogeneous firms that differ in size and behavior

unions and efficient training the paper examines the optimal level of training investment when trained workers are mobile wage contracts are time consistent and training comprises both specific and general skills the firm has ex post monopsonistic power that drives trained workers wages below the social optimum the emergence of a trade union bargaining at the firm level can increase social welfare by counterbalancing the firm s ex post monopsonistic power in wage determination local union firm wage bargaining ensures that the post training wage is set sufficiently high to deter at least some quits so that the number of workers the firm trains is nearer the social optimum
