labor market segmentation a cluster analysis of job groupings and barriers to entry real expenditures on public assistance programs have increased substantially in the past two decades as has real per capita income investments in a variety of education programs have risen and a number of jobs programs have been tried although there have been some gains for example a decline in the percentage of the population in poverty 31 474 a number of disparities persist unemployment remains at record levels and the prospect for sizable reductions in the unemployment rate seems quite small there are persistent differences between the mean household incomes of blacks and whites that have not narrowed at all during the past two decades 15 there is also a widespread perception that a disadvantaged segment of the u s population has no effective access to good jobs and if such persons get them they do not stay employed for long this means that many such adults are caught in a cycle of unemployment welfare dependency bad jobs and intermittent employment whereas there is nearly universal agreement that the persistent disparities in well being are undesirable there is considerable disagreement on what to do about this in part the disagreement stems from ignorance about the facts for example rigorous operational definitions of good and bad jobs have not been developed the notion that some persons do not have access to the good jobs is primarily based on anecdotes fortunately longitudinal data bases are now available that permit more rigorous empirical analysis of such issues

adjusting input output models for capacity utilization in service industries abstract the input output i o models assume the stability of economic ratios and regional multipliers over the evaluation period for manufacturing sectors constant multipliers within a short term period may present a reasonable picture of the real world production function tourism industry however is composed of a variety of services in which total output and factor inputs are strongly influenced by capacity utilization cu a conceptual model is proposed in this paper which purports that shifts in cu for perishable services will lead to economies of scale in inputs price changes in the final output capacity constraint on domestic supply and substitution between input factors especially between capital and labor these factors simultaneously modify i o ratios and multipliers traditional i o analysis which assumes constant economic ratios and multipliers will therefore lead to biases in tourism impact estimates especially to value added components as it does not reflect the changing costs of operation in response to shifting supply and demand

nonparametric measures of scale economies and capacity utilization an application to u s manufacturing abstract an economic measure of scale efficiency is the ratio of the minimum average cost to the average cost at the actual output level of a firm it is easily measured by the ratio of the total cost of this output under the constant and variable returns to scale assumptions this procedure does not identify the output level where the average cost reaches a minimum this paper proposes a nonparametric method of measuring this output level using dea the relation between this efficient production scale the short run physical capacity output and the most productive scale size mpss is also discussed an empirical application using state level data from u s manufacturing is used to illustrate the procedure the dea findings are further analyzed using a smoothed bootstrap procedure

primal and dual capacity utilization an application to productivity measurement in the u s automobile industry capacity utilization measures have traditionally been constructed as indexes of actual as compared to potential output this potential or capacity output y can be represented within an economic model of the firm as the tangency between the short and long run average cost curves economic theoretical measures of capacity utilization cu can then be characterized as y y where y is the realized level of output these quantity or primal cu measures allow for economic interpretation they provide explicit inference as to how changes in exogenous variables affect cu additional information for analyzing deviations from capacity production can be obtained by assessing the dual cost of the gap in this article the definitions and representations of primal output and dual cost cu measures are formalized within a dynamic model of a monopolistic firm as an illustration of this approach to characterizing cu measures a model is estimated for the u s automobile industry 1959 1980 and primal and dual cu

measuring and assessing capacity utilization in the manufacturing sectors of nine oecd countries following a tradition established by cassels klein and hickman we employ the economic theory of cost and production and define economic capacity output as that output at which short and long run average total cost curves are tangent to one another capacity utilization cu rates are then computed as the ratio of actual to capacity output we implement this framework empirically by specifying and estimating a translog variable cost function for the manufacturing sectors of nine oecd countries we find that by the end of the historical sample the early 1980s pervasive and chronic excess capacity exists while the average cost consequence of excess capacity was relatively modest in the 1960s the burden increased considerably after opec i and after opec ii the premium was as large as 15 of average total costs we also find that electricity and fuel price increases had small impacts on capacity output relative to that from labor or capital finally we adjust conventional measures of multifactor productivity growth for changes in cu and find that the adjusted growth is larger after 1973 than that based on traditional procedures

on the utilisation controversy a theoretical and empirical discussion of the kaleckian model of growth and distribution this paper examines the utilisation controversy around the kaleckian model of growth and distribution we show that the federal reserve data on capacity utilisation which have been used by both sides of this debate are the wrong kind of data for the issue under examination instead a more appropriate measurement can be derived from the data on the average workweek of capital we argue that the long run dynamic adjustment proposed by kaleckian scholars lacks a coherent economic rationale we provide an alternative path towards the endogeneity of the desired utilisation at the micro and macro levels finally we examine the proposed adjustment mechanism econometrically our results verify the endogeneity of the normal utilisation rate

long and short run non parametric cost frontier efficiency an application to spanish savings banks the utilisation rate of installed capacity is a popular concept in both the performance appraisal literature and in publications on industrial organisation however a common consensus has yet to be reached concerning the most appropriate way to measure the capacity utilisation of physical inputs and its final effect on company results on the one hand there are approaches that establish capacity utilisation with reference to the maximum level of production that can be achieved in contrast there are other approaches more strictly related to economic analysis of operating costs in this paper our main objective is to define an analytical process that uses non parametric frontier methodology to provide the distance between the total costs of a given unit and the short run frontier costs as a natural extension of this proposal it is possible to compute the short run inefficiency caused by a non optimal dimension of the fixed inputs we define this as capacityefficiency the proposed evaluation process is applied to spanish savings banks covering the period between 1986 and 1995 throughout the period analysed the greater part of cost inefficiency is due to capacity efficiency 2002 elsevier science b v all rights reserved

excess capacity and asymmetric information in developing country fisheries the malaysian purse seine fishery excess capacity poses a problem in many developing country fisheries these countries often pursue a development strategy aimed at expanding capacity under open access sustainable development however requires management principal agent issues from asymmetric information between the regulator and fishers which potentially form serious obstacles to fisheries management arise in the likely forms of management this article discusses principal agent issues and examines the principal agent moral hazard issue which is due to divorce of ownership and vessel operations the article also illustrates a method for estimating capacity when information is limited the peninsular malaysian purse seine fishery forms a case study

cost structure and capacity utilisation in multi product industries an application to the basque trawl industry to empirically study production structure and the capacity level at which vessels are harvesting a short run translog cost function is estimated from the estimated parameters two capacity utilisation measures are calculated ray returns to scale and a dual capacity utilisation measure both capacity utilisation measures suggest that there is excess capacity in the basque trawler fleet these measures are also estimated annually and they indicate the same conclusion the basque trawler fleet can therefore gain from increased production levels

an analysis of the spanish electrical utility industry economies of scale technological progress and efficiency abstract in this paper we propose a model to explain the behaviour of the spanish electrical utility industry during the period 1987 1997 under the then existing regulatory system marco legal estable the paper will study the presence of economies of scale the effect of technological progress and the differences in the efficiency of the different companies within the market the paper concludes that the spanish electrical utility industry was not in fact characterized by economies of scale during this period but witnessed a great improvement in efficiency within that period all the critical market factors remind stable

capacity utilization measures underlying economic theory and an alternative approach measures of industrial capacity utilization hereafter cu have been used extensively in helping to explain changes in the rate of investment labor productivity and inflation the cu measures have also been used to obtain indices of capital in use as distinct from capital stock in place a number of alternative measures of cu are periodically calculated and published the 1980 economic report of the president for example contains three series that by the federal reserve board the u s department of commerce bureau of economic analysis and the wharton school of finance other publicly available series are those prepared by mcgraw hill publishing company the u s department of commerce bureau of the census and rinfret boston associates inc although a host of cu measures is publicly available it is not at all clear how one should interpret changes over time in each measure or variations among them a principal reason underlying these interpretation problems is that the crucial link between underlying economic theory and the constructed measure of cu is weak one way in which this issue has manifested itself in the policy domain over the last five years has been with respect to the uncertain effects of dramatic increases in energy prices on capacity output and on cu each of the cu measures noted above is computed in such a way that explicitly ignores any role for energy prices yet several times during the last decade though growth to apparently high rates of cu had taken place investment and average labor productivity were much lower than expected and the rate of price increase much greater in brief during the last decade the explanatory power of alternative cu measures has dropped sharply some have conjectured that post opec energy price increases may have brought about major changes in the u s economy so that old quantitative relationships between measured cu and investment labor productivity and price inflation may have been altered substantially in order to assess effects of changes in pe on cu a re examination of the notion and measurement of cu is needed based on the framework of the economic theory of the firm that is the focus of this paper

further evidence of the relevance of the dual labor market hypothesis for the u k this study proposes that the earnings of career employees are influenced by a different set of parameters from the earnings of non career employees the above proposition is tested by using a matched employer employee sample within the econometric

estimation of profit functions when profit is not maximum this paper deals with derivation and implications of profit functions when profit is not maximum due to the presence of either technical inefficiency or allocative inefficiency or both we show that input demand and output supply elasticities and returns to scale are in general affected by these inefficiencies we also show that the overall profit efficiency is not necessarily the product of technical and allocative efficiencies meaning that technical and allocative inefficiencies are not necessarily independent estimation techniques are developed for both cross sectional and panel data models working of the model is illustrated using a panel of 60 salmon farms copyright 2001 oxford university press

did the tax revolt reduce school performance abstract this paper uses detailed school level data from 49 states to analyze the effects of tax revolt era property tax limitations on school services i find that limitations are associated with larger student teacher ratios and lower cost of living adjusted starting teacher salaries all else equal these results are robust to modelling the results as endogenous and using a variety of measures for whether the limitation binds at particular schools however i find no such evidence that schools subject to limitations have reduced their administrative costs furthermore i find that limitations are associated with lower student performance on mathematics science social studies and reading examinations all else equal

comparative performance of short run capacity utilization measures abstract we present parametric estimates for primal and dual capacity utilization and then evaluate their comparative performance empirical findings indicate that alternative capacity utilization ratios depending upon the reference variables are procyclically consistent with each other

on the measurement of capacity utilization capacity utilization is usually defined as the ratio of actual output to the output corresponding to 1 the minimum point on the short run average total cost curve and 2 the point of tangency between the long run average total cost and short run average total cost curves in practice however capacity utilization is often measured as the ratio of actual to the maximum potential output consistent with a given capital stock this paper demonstrates how to estimate the theoretical measures of capacity utilization and examines the correlation between three measures of capacity utilization and the mcgraw hill estimates of capacity utilization using data from a sample of u s privately owned electric utilities for 1961 83 copyright 1989 by blackwell publishing ltd

sustainable fisheries development in the tropics trawlers and licence limitation in malaysia sustainable fisheries development requires sound fisheries management area licence limitation programmes may form the cornerstone for most tropical multispecies fisheries management programmes an empirical analysis of peninsular malaysian fishing trawlers is used to design an area licence limitation programme that conforms to the multiproduct production technology and cost and revenue structures to best accommodate condtions of asymmetric information between the regulator and fishing vessels

segmented labour markets and the estimation of wage functions this paper uses a stratified random sample of private sector employees to estimate wage equations for both the male labour market as a whole and six segments of the labour market segement which are defined with respect to the industry and size characteristics of the employing establishmen highly conventional results are obtained when wage equations are estimated for the male labour market as a whole or within two segements comprising almost half the survey population however one can reject conclusively the hypothesis that the same estimating equation is appropriate for modelling wage determination in all segments and if a human capital hk model is within segements tested against more appropriate alternative hypotheses for wage determination using the davidson and mackinnon 1981 methodology for the testing of non nested hypotheses the conclusion is that one should reject the hk specification and not reject the alternative it is therefore argued that the disaggregation of labour market dat

labour market segmentation a local labour market analysis using alternative approaches earlier studies have generally attempted to establish the presence or otherwise of labour market segmentation using a single technique using data drawn form the british social and economic life initiative sceli for six local labour markets this paper tests for segmentation using four different methods of analysis a simple career non career model cluster analysis and switching regressions the results in general suggest that explanatory power is not improved by analysing the labour market in different segments but this simple career model points to higher rewards for given characteristics in the career sector and the results of the switching regression model are consistent with duality in one of the six markets

trends in earnings differentials by gender 1971 1981 this paper clarifies trends in relative earnings by sex over the decade 1971 1981 and decomposes these trends to determine which factors contributed to a decline and which to an increase our analyses are based upon data from the annual demographic files of the current population survey for 1972 and 1982 this study is unique in that it estimates earnings functions in each year which are corrected for selectivity bias it is found that such a correction markedly raises the progress of white women relative to men among blacks the impact of the selectivity bias correction was to substantially lower the relative earnings increase of women however the coefficients on the selectivity variable were not significant the findings suggest declining sex role specialization and discrimination as conventionally measured over the decade on the other hand contrary to expectations the total effect of variables reflecting the sex composition of the individuals occupation worked to widen the sex differential over the period the sex differential was also adversely affected by a decline in the relative return to education especially for whites authors modified

factor substitution and economies of scale and utilisation in kuwait s crude oil industry abstract the cost structure of the crude oil industry in kuwait has been examined with specific focus on factor substitution and economies of scale and utilisation this has been done by estimating translog cost functions both long run and short run using time series data covering the period from 1976 to 1996 the results indicate that the implied production structure is non homothetic and the pattern of scale effect is labour saving but capital and material using the evidence also supports the presence of an induced exogenous technical change which is non neutral labour and capital using and material saving the elasticity of substitution between capital and labour is positive implying that the two inputs are substitute the results also indicate the existence of diseconomies of scale in the production of crude oil but no economies or diseconomies of utilisation

from common fish to rights based fishing fisheries management and the evolution of exclusive rights to fish abstract since the second world war the international law of the sea has been altered fundamentally an exclusive economic zone eez extending 200 nautical miles from baselines has been established in which the coastal states have practically full sovereignty over natural resources including fish this development appears explicable in the light of the economic theory of property rights due to increased scarcity of fish and lower costs of supporting claims to fish resources the eez has major implications for the efficient utilization of fish resources through its limitation of free access in some cases it amounts to the establishment of national property rights to fish resources while in others the number of parties with a legitimate claim to access has been restricted in the wake of this fisheries management by total allowable catches tacs has become widespread this method of management has a potential for increasing the efficiency of fisheries given that a single state or a group of states are able to control the fishery how should this be done to ensure efficiency four methods are discussed i privatization of the resources ii taxes on landings or fishing activity iii fishing licences and iv individual transferable quotas itqs some questions related to itqs are discussed i fixed itqs versus shares in the tac ii stable versus variable itqs and iii how the tac should be set for each particular year the economic theory of property rights predicts the emergence of private property rights to fish stocks or fishing rights in the present situation recent cases of such rights emerging are discussed

the distributional effects of new jersey s tax and expenditure limitation when state governments issue general rules that dictate the spending or tax policies of varied local municipalities they distort local government outcomes one example of this is state limitations on local government authority to levy taxes and make expenditures although state imposed tax and expenditure limits tels have been used throughout much of the united states s history they have recently stimulated attention in both the mass media and the academic press in practice tels can be divided into limitations on the authority of local governments to 1 make expenditures and 2 collect property taxes according to a 1981 tabulation of the advisory commission on intergovernmental relations acir reprinted in gold 1983 p 112 46 states had some kind of limitation on local county municipal or school governments ability to collect property taxes and 6 states imposed general expenditure limitations on local governments many of these controls are quite recent in origin in fact all but 18 of the 46 states with property tax limits enacted them after 1970 though some may have had earlier laws restricting the use of the property tax and all of the general expenditure limits were enacted after 1970 a particularly rapid wave of tels followed california s approval of proposition 13 which reduced property taxes there to one percent of assessed value in june 1978 in november 1978 just five months after proposition 13 was approved voters in alabama michigan nevada and texas approved legislation or constitutional amendments that reduced the authority of local governments to raise taxes 2 while many tels set maximum property tax rates and expenditure limits that do not appea to have much effect on the behavior of l cal governments others such as those in california massachusetts and new jersey do a pear to be binding on many localities several r cent studies have attempted to empirically measure the effects of tels 3 the most well known of these studies is a 1977 acir study that used a dummy variable indicating the pres nce or absence of property tax rate and or levy limits along with other independent variables to explain total per capita local own source government expenditures in each of the 50 states primarily because the estimated parameters of these dummy variables were negative and significantly different from zero the acir concluded that tels have reduced government spending further analyses showed the average tel reduced spending 6 to 8 percent inman s 1979b paper which used fiscal year 1966 67 data also employed dummy variables to indicate the presence or absence of various kinds of tax rate limits but used data disaggregated at the city level inman found a positive and insignificant coefficient on all dummy variables and concluded that efforts to regulate local taxation in 1967 through

impacts of random noise and specification on estimates of capacity derived from data envelopment analysis abstract data envelopment analysis dea is widely used to estimate the efficiency of firms and has also been proposed as a tool to measure technical capacity and capacity utilization cu random variation in output data can lead to downward bias in dea estimates of efficiency and consequently upward bias in estimates of technical capacity this can be particularly problematic for industries such as agriculture aquaculture and fisheries where the production process is inherently stochastic due to environmental influences this research uses monte carlo simulations to investigate possible biases in dea estimates of technically efficient output and capacity output attributable to noisy data and investigates the impact of using a model specification that allows for variable returns to scale vrs we demonstrate a simple method of reducing noise induced bias when panel data is available we find that dea capacity estimates are highly sensitive to noise and model specification analogous conclusions can be drawn regarding dea estimates of average efficiency

static efficiency decompositions and capacity utilisation integrating economic and technical capacity notions starting from existing static decompositions of overall economic efficiency on nonparametric production and cost frontiers this article proposes more comprehensive decompositions including several cost based notions of capacity utilization furthermore in case prices are lacking we develop additional decompositions of overall technical efficiency integrating a technical concept of capacity utilization these new efficiency decompositions provide a link between short and long run economic analysis and in empirical work avoid conflating inefficiency and differences in capacity utilization an empirical analysis using a monthly panel of chilean hydro electric power plants illustrates the potential of these decomposition proposals

earnings determination and labour markets gran santiago chile 1978 abstract the purpose of this study is twofold first to ascertain whether or not there are statistical differences in the structure of earnings functions among workers in various sectors of economic activity second to provide a test of the human capital approach in the explanation of earning differentials among wage earners using individual characteristics of full time wage earners in santiago the results show that the structures of earnings functions are not statistically different across sectors of economic activity also the application of a human capital model shows that about 50 percent of the relative dispersion of earnings may be attributed to differences in schooling and experience

changes in earnings inequality and labour market segmentation metropolitan santiago 1969 78 changes in earnings inequality are examined in this article through an eclectic approach allowing for differences in human capital earnings function by labour market segments several findings are of interest the first are the components of earnings inequality changes these being in order of importance changes in the within segments inequality changes in the relative share of the informal sector segment and changes in relative income between segments second these changes are found to be the result of labour market liberalisation policies such as abolition of both minimum wages and labour turnover legislation in the formal sector the promotion of self employed activities in the informal sector and the selective mobility pattern between segments

segmented labour markets theory and evidence this paper examines the possibility of accepting the labour market segmentation approach as a valid alternative to the classical and neo classical analysis of labour markets it consists of three main parts the urst part contains a historical analysis of both the distant and recent origins of the labour market segmentation hypothesis part two outlines the central ideas of both segmentationalists and radical theorists who attempted to explain the fragmented nature of labour markets and the importance of institutional and social inuuences upon pay employment and mobility of individual workers between different labour market sectors the third part examines the case for labour market segmentation using four alternative techniques and discusses the issue of mobility among different labour market segments it is thereby concluded that the lack of agreement among the segmented labour market theorists on both theoretical and methodological issues has prevented them from developing a consistent and convincing argument based on veriuable empirical evidence to validate their thesis

testing spanish labour market segmentation an unknown regime approach this paper studies the existence of two differentiated segments primary and secondary in the spanish labour market for this a methodology switching regression model with unknown regimes is used which on the one hand does not demand a priori demarcation of segments and on the other enables the allocation of workers to the segments to be treated as a factor endogenous to the model itself and closely connected with the wage setting mechanisms operating in the segments the empirical results show that the assignment to segments is not random and that there are substantial differences in the wage determination process between the two sectors furthermore the model estimated has allowed analysis of the ex post composition of the segments and corroboration to a large extent of the predictions of the dual labour market theory

production efficiency and exit in rights based fisheries economic theory predicts that the least efficient vessels are more likely to exit a fishery following the transition to an individual transferable quota itq management regime tools are needed to help analysts predict the likely degree and distribution of consolidation prior to implementing itq programs this research utilizes a one stage estimation procedure to determine the degree to which one s technical inefficiency preceding an itq regime influences the likelihood of exiting our results indicate that a vessel s measure of technical inefficiency is a significant and positive factor in explaining whether it exits the fishery following the implementation of itqs jel q22

segmented or competitive labour markets a normal roy model with four sectors is developed it allows to derive tests of several assumptions on the working of the labor market strongly or weakly competitive or segmented it shows that more important a feature of labor markets than segmentation is the presence of comparative advantages for individuals between the various economic sectors the model is applied to data on women s labor force participation in the main towns of colombia in 1980 it uses multivariate probit and tobit techniques copyright 1991 by the econometric society

a theory of dual labor markets with application to industrial policy discrimination and keynesian unemployment this paper develops a model of dual labor markets based on employers need to motivate workers in order to elicit effort from their workers employers may find it optimal to pay more than the going wage this changes fundamentally the character of labor markets the model is applied to a wide range of labor market phenomena it provides a coherent framework for understanding the claims of industrial policy advocates it also can provide the basis for a theory of occupational segregation and discrimination that will not be eroded by market forces finally the model provides the basis for a theory of involuntary unemployment

the quantitative consequences of raising the u s saving rate the authors investigate the consequences of a permanent unphased increase in the u s gross saving rate they find that the sacrifice time the time that elapses until consumption surpasses the value it would have had under the initial saving rate is roughly six years and is insensitive to the percentage increase in the saving rate delta sub s the percentage gain in output at the end of decade the decade gain is roughly 26 of delta sub s while the percentage gain in consumption is roughly 8 of delta sub s the saving rate return the internal rate of return on a permanent increase in the saving rate is roughly 16 and is insensitive to delta sub s copyright 1991 by mit press

male female disparity in starting pay empirical studies of the earnings of male and female workers persistently reveal a gap that is unexplained by the economic variables in these models this gap has been given two interpretations in the literature one holds that the gap reflects non market forces which distort the equilibrium relation among the wages of competing workers discrimination according to this view prevents female workers from being offered jobs commensurate with their qualifications and crowds them into low productivity occupations 2 the alternative interpretation holds that some substantial portion of the gap is an artifact the result of missing variables biased parameters or measurement error these researchers view the labor market as highly competitive and were it possible to correct for all these statistical problems the measured wage gap would largely vanish 3 this research belongs to the latter category we argue that a portion of the measured gap at least that observed between the earnings of young men and women during their first few years with their employers reflects sex related differences in the shares of investment in firm specific human capital borne by workers of each group moreover these variations in investment levels are freely chosen by women and in no way imply long run deficits in their earning power on the contrary the model predicts steeper earnings profiles of women who undertake this firm specific investment thus women s earnings are predicted eventually to overtake and surpass those of equally qualified men this theory was developed in earlier research by becker and lindsay 2 based on a model of hashimoto 11 12 and extensions by parsons 21 we argued that young women for nondiscriminatory reasons elect to shoulder a larger share of this investment than young men the explanation for this is developed in two stages the first derives the terms under which both male and female workers share the investment with their employers the second argues that female workers will be led by these considerations to bear a larger share workers of both sexes agree to enter into inflexible wage contracts with employers specifying a share of the investment i e a wage deduction from current mvp and a post investment wage the advantage to such contracts lies in the solution to an assymetric information problem the

segmented labor markets new evidence from a study of four race gender groups using data from a supplement to the 1983 current population survey the author tests hypotheses of segmented labor market theory two labor market sectors a primary sector and secondary sector are identified on the basis of occupational segmentation as inferred from workers answers to the question of whether specific skills or prior training were conditions for their employment the results show significant unexplained earnings differentials across sectors for each of four groups black men black women white men and white women other segmented labor market hypotheses are also generally supported by the results but distinct variations are found across the four groups

are there dual labor markets in chile empirical evidence abstract in this paper we use a switching regression method to test the hypothesis that segmentation in the chilean labor market exists the results support the labor segmentation hypothesis and consequently they contradict those of corbo and stelcner 1983 the explanation for this is that we do not make any a priori definition of the population as corbo and stelcner do in fact our results show that any a priori definition of the sample will lead to rejecting the segmentation hypothesis

a test of dual labor market theory despite substantial differences in their views of the appropriate policy response to the existence of poverty neither the proponents of dual market theory nor its critics have proposed potentially conclusive tests of the dual market hypothesis this paper presents a test of the two central propositions of dual market theory 1 the existence of two distinct labor markets with different wage setting mechanisms and 2 the existence of barriers to mobility between the labor markets we find considerable support for both hypothesis estimation of a switching model of wage determination with unknown regimes yields two distinct wage equations the one which most workers are associated with closely resembles the standard human capital regression with significant returns to education and experience the other equation is flat with no returns to human capital these two equations resemble the predictions of dual market theory for the primary and secondary markets respectively further we present evidence that at least some non white workers are involuntarily confined to the secondary market this crowding of minority workers into the low wage labor market accounts for a substantial portion of white non white wage differences we interpret these results as providing empirical support for the dual market hypothesis and for recent theoretical work on efficiency wagemodels in addition combining the efficiency wage argument with the observation that much of the white non white wage difference is explained by the exclusion of non whites from the primary sector suggests an explanation for the persistance of wage differences this abstract was borrowed from another version of this item

estimation of cost functions in a data poor environment the case of capacity estimation in fisheries fisheries economic analysis is often handicapped by the lack of adequate data to undertake robust econometric analyses in this study a translog cost function was required to estimate the potential direction of adjustment in a uk fleet segment if a new regulatory regime was introduced however the available data were not appropriate for such estimation data envelopment analysis dea was used to modify the data subsequently used in the estimation of the long run cost function the resulting model appears robust and is consistent with economic theory and the supporting evidence produced using dea

multi output nonfrontier primal measures of capacity and capacity utilization this article implements an econometric approach for generating primal capacity output and utilization measures for fisheries in situations where regulatory environmental and resource conditions affect catch levels but are not independently identified in the data frontier based capacity models may interpret such impacts as production inefficiency however if such inefficiencies are unlikely to be eliminated the implied potential output increases may be unrealistic we develop a multi output multi input stochastic transformation function framework that permits various assumptions about how output composition may change when operating at full capacity we apply our model to catcher processor vessels in the alaskan pollock fishery

assessing efficiency gains from individual transferable quotas an application to the mid atlantic surf clam and ocean quahog fishery delayed fishing fleet restructuring complicates the assessment of efficiency gains from individual transferable quota itq fisheries management programs this article presents a methodology to estimate harvest sector efficiency gains in lieu of incomplete fleet restructuring the methodology is applied to assess the efficiency gains in the mid atlantic surf clam and ocean quahog fishery itq program while roughly 128 vessels harvested clams under the previous management regime the analysis suggests that 21 25 vessels will remain under ltqs the efficiency gains are estimated to be between 11 1 million and 12 8 million annually 1990 dollars

the effects of an increase in power rate on energy demand and output price in korean manufacturing sectors in korea price subsidies for industrial power are provided by the government in order to enhance industrial competitiveness and curb inflation however this repeatedly causes electricity shortages in the peak summer and winter seasons because of over consumption forcing a decline in the demand for electricity by raising power rates would thus help prevent a national blackout lowering dependence on foreign energy and reducing co2 emissions cost effectively this paper simulates the effects of a rise in power rate on demand for electricity and output price by estimating a restricted cost function in which the quantity of raw materials is set to its cost minimizing level jointly with an inverse supply relation for the top three electricity intensive manufacturing sectors the empirical results indicate that a 10 increase in electricity rate would result in 8 0 10 1 less demand across all three manufacturing sectors ceteris paribus the impact on output price is of little statistical significance in the basic metals sector while output price on average falls by 0 16 in the tv and communication equipment sector

the reemergence of segmented labor market theory according to dual labor market theory the labor market can be usefully described as consisting of two sectors a high wage primary sector with good working conditions stable employment and substantial returns to human capital variables such as education and experience and a low wage secondary sector with the opposite characteristics moreover primary jobs are rationed that is not all workers who are qualified for primary sector jobs and desire one can obtain one finally the sector of the labor market in which an individual is employed directly influences his or her tastes behavior patterns and cognitive abilities thus the dual labor market model or more generally segmented labor market models is simultaneously a description of the income distribution a claim about the absence of market clearing and a radical departure from the standard neoclassical assumption of fully rational actors and exogenously determined preferences while this last element is potentially the most interesting even its proponents fail to give it the attention it deserves and related work has not been incorporated into the segmented labor market model in this paper we therefore concentrate on the first two elements of the model segmented labor market theory was sufficiently popular in the late 1960 s and early 1970 s to be taken seriously by prominent mainstream labor economists however two influential and largely negative reviews glenn cain 1976 michael wachter 1974 portrayed the segmented labor market hypothesis as largely atheoretical and based at best on questionable statistical analysis it seems fair to say that even sympathetic mainstream critics felt that key insights from the segmented labor model could be incorporated into neoclassical analysis and that the remaining elements of the model did not form a sufficiently coherent theory to pose a challenge to the neoclassical model whatever the merits of this perception it is clear that advocates of the segmented labor market approach did not develop a formal theory which conformed to the standards of mainstream economists with some notable exceptions michael piore 1975 david gordon 1972 the work was atheoretical moreover the empirical methods used tended to fall outside the norm for example interviews observational studies and historical and institutional analysis advocates of the segmented labor market perspective mostly radical political economists chose instead to develop their own research program outside the mainstream the reemergence of segmented labor market theory is linked with the reversal of these two tendencies the theory has been pursued by economists using modern tools of imperfect information theory and state of the art econometrics as a result the approach has again attracted the attention of the mainstream even a few years ago it would have been a clairvoyant observer who predicted that lawrence summers would be working on a theoretical model of labor market duality with jeremy bulow 1986 that robert solow would count among his recent work a dual market model with ian mcdonald 1985 and that james heckman would publish an article in which he undertook an empirical test of a dual market model failed to reject the model and then devoted much of the rest of the article to attacking his and other tests of the dual labor market view see his article with v joseph hotz 1986 since the theoretical developments are largely associated with efficiency wage and departments of economics university of california berkeley ca 94720 and nber and boston university 270 bay state road boston ma 02215 and nber respectively this study was supported in part by nsf grant no ses 8606139 lang acknowledges support from a sloan faculty research fellowship dickens acknowledges support from the institute of industrial relations at berkeley

tax and expenditure limitations and the fiscal relationships between state and local governments this paper uses comprehensive data on state and local tax and spending limitations for forty nine states between 1976 and 1990 to estimate the effects of these limits on the fiscal relationships between state and local government results indicate that tax and spending limits on local governments are only partially effective in reducing revenues because political agents bypass limitations by transferring revenue reliance to unconstrained revenue sources or because unconstrained levels of government take on additional revenue responsibilities in particular the empirical analysis demonstrates that binding local government fiscal constraints are associated with reductions in local revenues and increases in state aid to local governments in contrast state government limitations are related to reductions in both state and local own source revenues

an investigation of the labor market earnings of panamanian males evaluating sources of inequality this paper presents empirical evidence on the determinants of labor market earnings and inequality for males in panama using newly available microdata we estimate earnings equations based on the measurement framework of mincer 1974 and compare them with those for other countries at various stages of economic development we present evidence on two aspects of inequality in less developed economies labor market segmentation and social stratification we present tests of the segmentation hypothesis including several of the dual labor market hypotheses and discuss their inherent ambiguity we also present evidence on the importance of family background for earnings determination and educational attainment

capacity utilisation and profitability a decomposition of short run profit efficiency the principal aim of this paper is to measure the amount by which the profit of a multi input multi output firm deviates from maximum short run profit and then to decompose this profit gap into components that are of practical use to managers in particular our interest is in the measurement of the contribution of unused capacity along with measures of technical inefficiency and allocative inefficiency in this profit gap we survey existing definitions of capacity and after discussing their shortcomings we propose a new ray economic capacity measure that involves short run profit maximisation with the output mix held constant we go on to describe how the gap between observed profit and maximum profit can be calculated and decomposed using linear programming methods the paper concludes with an empirical illustration involving data on 28 international airline companies the empirical results indicate that these airline companies achieve profit levels which are on average us 815m below potential levels and that 70 of the gap may be attributed to unused capacity

inter industrial wage differentials evidence from latin american countries the recent literature on inter industrial wage differentials for the united states suggests that the labour market equilibrium features non competitive elements however the lessons from the united states need not carry over to other countries especially developing economies this article analyses the wage differentials in selected latin american countries despite the sharp contrasts between the latin american and the us economies our results show more similarities than differences with those reported in past studies wage differentials are substantial and persist over time the differentials are also correlated across occupations and to a lesser extent across establishment sizes

firm entry excess capacity and endogenous productivity abstract we show that sluggish firm entry causes productivity to vary endogenously in response to technology shocks the endogenous productivity effect is caused by incumbent firms utilizing excess capacity as entry adjusts we develop a nonparametric model of endogenous sunk costs and monopolistic competition to show that imperfect competition and dynamic entry are necessary and jointly sufficient conditions for endogenous productivity fluctuations quantitatively we show the endogenous productivity effect is as large as that from a traditional capital utilization effect

measures of capacity utilization and its determinants a study of indian manufacturing we estimate capacity utilization cu rates in for selected industries in indian manufacturing for the 20 year period 1976 1996 we estimate a generalized leontief variable cost function with capital as a quasi fixed input to derive our cu measures using error component techniques we note substantial variations in cu both across industries and over time in general we find that cu rates were higher in the earlier time period dropped in the mid 80s and started rising again in the early 90s cu rates in our analysis are sensitive to input prices with the sole exception of the price of labor we also confirm the standard result that variations in demand are a significant driving force for variations in cu we find that cu is positively related to the magnitude of labor intensity in production this holds for both between industries and within industries empirical results also indicate that traditional measures of cu such as minimum capital output ratio and peak to peak are not appropriate proxies for

decomposing capacity utilization in data envelopment analysis an application to banks in india abstract this paper briefly reviews the existing methods of capacity utilization in nonparametric framework from economic perspectives and then suggests an alternative in the light of limitations therein in the spirit of work by coelli et al coelli t j grifell tatje e perelman s 2002 capacity utilisation and profitability a decomposition of short run profit efficiency international journal of production economics 79 261 278 we propose two methods radial and non radial to decompose the input based physical technological capacity utilization into various meaningful components viz technical inefficiency ray economic capacity utilization and optimal capacity idleness a case study of indian banking industry is taken as an example to illustrate the potential application of these two methods of decomposition our two broad empirical findings are that first competition created after financial sector reforms generates high efficiency growth and reduces excess capacity second the cost gap of the short run cost from the actual cost is higher for the nationalized banks over the private banks indicating that the former banks though old do not reflect their learning experience in their cost minimizing behavior

fishing effort validation and substitution possibilities among components the case study of the viii division european anchovy fishery command and control regulation programmes particularly input constraints typically fail to achieve stated objectives because fishermen may substitute unregulated for regulated inputs it is thus essential to have an understanding of the internal structure of production technology a primal formulation is used to estimate a translog production function at the vessels level that includes fishing effort and fisherman s skill the flexibility of the selected functional permits the analysis of the substitution possibilities among inputs by estimating the elasticity of substitution with no prior constraints particular attention is paid to the empirical validation of fishing effort as an aggregate input which implies either the acceptance of the joint hypothesis that inputs making up effort are weakly separable from the inputs out of the subgroup or considering that effort is an intermediate input produced by a non separable two stage technology cross sectional data from the spanish purse seine fleet op

cost structure and capacity in the norwegian pelagic fisheries the parameters of the short run cost function are estimated for three vessel types taking part in the norwegian pelagic fisheries purse seine vessels trawlers and coastal vessels the generalized translog functional form is used estimates of returns to scale are calculated and the results indicate that there are substantial economies of scale in all vessel classes it is further investigated whether excess capacity varies with vessel size and age the analysis suggests increased quotas per vessel to avoid rent dissipation with the total allowable catch given the number of participating vessels must be reduced

revenue based capacity utilisation measures and decomposition the case of danish north sea trawlers in fisheries capacity analysis has largely been limited to measuring physical capacity defined as the maximum amount of output that can be produced per unit of time given existing plant and equipment and unrestricted availability of variable inputs an economic measure of capacity can be defined as the maximum revenue attainable for the given fixed inputs using relevant outputs and output prices this paper examines these two approaches to capacity by applying data envelopment analysis to physical and economic input output data for danish north sea trawlers the economic and physical measures are compared and contrasted using correlation analysis an innovative analysis into the composition of possible revenue increments is also presented and reasons for economic inefficiency of vessels are identified

technical efficiency effects of input controls evidence from australia s banana prawn fishery this paper provides the first ex post estimates of the effects of input controls on technical efficiency in a fishery using individual vessel data from the northern prawn fishery of australia for the years 1990 1996 and 1994 2000 stochastic production frontiers are estimated to analyse the efficiency impacts of input controls on engine and vessel size the results indicate that technical efficiency is increasing in a measure of vessel size and engine capacity that was controlled by the regulator from 1985 to 2001 and decreasing in an unregulated input gear headrope length the study shows that fishers have substituted from regulated to unregulated inputs over the period 1990 2000 and technical efficiency has declined coincident with increasing restrictions on vessel size and engine capacity the decline in technical efficiency indicates that the goal of the regulator to increase economic efficiency has not been realized

segmented labour markets in australia the concept and measurement of segmented labour markets has received little attention in australia here a method for establishing a taxonomy of occupaions according to characteristics associated with the segmented labour market hypothesis is presented using this taxonomy the distribution of workers in australia according to gender migrant status and trade union membershipis examined

interrelated factor demands for manufacturing a dynamic translog cost function approach abstract in this paper we report the results of estimating a joint model for labour capital and energy using the transcendental logarithmic cost function of christensen jorgenson and lau 1973 this allows us to determine both the own price and cross elasticities of substitution between labour capital and energy we combine a model of factor shares with a dynamic adjustment process for each factor we also impose on the cross equation restrictions necessary to provide additivity homogeneity and symmetry since the covariance matrix in systems of share relationships is singular we follow the suggestions of anderson and blundell 1982 and employ a mullivariate error corrrection model the results suggest that additivity symmetry and homogeneity restrictions do hold and that there are short run increasing returns to scale

experience tenure and the perceptions of employers this paper examines how group based assessments concerning employee ability impact employee compensation the employer learns about worker ability through bayesian updating creating an additional channel for wage growth that is not available to those workers with only general labor market experience consistent with the model s predictions results from national longitudinal survey of youth nlsy indicate that black workers fare much better relative to white workers in returns to tenure than in returns to experience finally parameter estimates in the structural model suggest that employers initially undervalue black males but that their wages rise with learning by employers over time on average black males earn lower wages than white males just as average wages differ across many groups this paper examines one explanation for this wage gap the possibility that employers underestimate the ability of workers in one or more groups in particular this paper proposes a model that provides explicit predictions about the affect of employer s perceptions on workers returns to general experience and tenure on the job we then examine the wage growth of young males to see whether patterns are consistent with the model economic theory provides many other explanations for differences in wages across groups

capacity utilization and its determinants for a container shipping line theory and evidence under utilization of fleet capacity appears to be a long lasting issue in the container shipping industry also there are some difficulties unsolved while measuring the ratio of capacity utilization cu of a container shipping line from the perspective of an engineering approach the slots capacity installed is the most popular way to represent the capacity output since the slots capacity installed lacks theoretical support this study adopts an economics model to find the capacity output of a shipping line further the derived cu ratio identifies the realized utilization of fleet capacity for a shipping line focused on the three largest container shipping lines in taiwan this article shows that their fleet capacity are totally under utilized and the movement patterns of cu ratios are approximately identical in addition the variations of cu ratios also suggest that the enactment of ocean shipping reform act has contributed a positive effect on the capacity utilization of a container shipping line
