does private management of water supply services really increase prices an empirical analysis in spain this paper attempts to explain differences in the average price of domestic water supply services in spain paying special attention to the effects of privatisation of the service on price levels the empirical analysis is based on the application of a treatment effects model on a sample of 53 major urban municipalities this model accounts for the fact that municipalities do not randomly distribute themselves between a group using strictly public ownership and management and a group where all or part of the service has been delegated to a private firm it is found that once this endogeneity is taken into account there seems to be a positive and significant effect of privatisation on water price levels

nonparametric estimation of sample selection models sample selection models provide an important way of accounting for economic decisions that combine discrete and continuous choices and of correcting for nonrandom sampling nonparametric estimators for these models are developed in this paper these can be used for estimating shapes and important economic quantities as in standard nonparametnc regression endogeneity of regressors of interest is allowed for series estimators for these models are developed which are useful for imposing additivity restnctions that arise from selection corrections convergence rates and asymptotic normality results are derived an application to returns to schooling among australian young females is given

industry structure and the speed of price adjustment recent work has suggested that there is an association between the degree of concentration in an industry and the speed at which prices adjust to changes in prime costs cagan 8 domberger 12 13 scherer 21 p 356 and the references cited therein apart from its intrinsic interest to students of industrial economics there would seem to be three reasons for investigating this association first to see what light if any it throws upon the influence of industrial structure on the price level together with the rate and process of inflation secondly to test the assumption made in some influential studies e g godley and nordhaus 15 coutts godley and nordhaus 10 and haig and wood 18 that the size of the lag between cost and price changes is solely dependent upon the length of the fabrication production and delivery period in the various industries the third reason is a belief held by the author that distributed lag coefficients in econometric studies should be subject to analysis and not left hanging in the air as part of the development of a large scale econornetric model of the australian economy the imp model a team of researchers under the direction of dr brain at melbourne university have estimated price prime cost equations for 43 manufacturing sectors using annual data referring to the period 1948 49 1973 74 1 the estimating equation is of the form

factor inputs and japanese manufacturing trade structure the japanese international trade structure in manufactured goods has been analyzed using cross section regression analysis in which labor capital human capital and energy are regressed on japanese net exports exports and imports with the world oecd and developing countries for 1967 and 1975 skill and wage differential measures have been utilized for the measuring of human capital contrary to the dualism found in earlier studies the estimated results show that in 1967 japan exported unskilled labor intensive goods with respect to the developing countries as well as the oecd countries in 1975 japan exported capital intensive goods to all regions and imported unskilled labor intensive goods from the world and the developing countries skilled labor intensive goods were imported from the oecd countries in both years drastic changes between 1967 and 1975 are noted japanese exports shifted from unskilled labor intensive goods to capital intensive goods while imports did the opposite this result conforms to the changes in unskilled labor and capital usage in japan and her major trading partners

effects of family background on earnings and returns to schooling evidence from brazil we investigate whether omitted family background variables are responsible for high returns to schooling estimated in brazil returns to schooling fall by about one third when parental schooling is added to wage equations surprisingly the schooling of fathers in law has larger effects on wages than the schooling of fathers on the basis of a model of assortative mating we interpret this as evidence that parental characteristics represent unobservable worker attributes rather than nepotism in the labor market we conclude that the family background bias in returns to schooling is modest and need not imply returns to family connections

taxes tariffs and transfer pricing in multinational corporate decision making three interrelated aspects of u s multinational corporation activity are analyzed here the ability to shift profits from high tax countries to low tax countries the impact of host country taxes and tariffs on the distribution of real capital and the influence of these policies on international trade patterns of the united states and host countries the cross sectional empirical analysis indicates that the observed pattern of reported profits in high and low tax countries is consistent with income shifting behavior and that real investment responds to host country effective tax rates and tariffs the united states appears both to import more from and export more to low tax countries where mnc investment is greater but this bilateral focus must be amplified to consider multilateral effects if trade benefits are to be projected copyright 1991 by mit press

occupational attainment and gender earnings differentials in mexico women earned about 20 8 less than men in mexico in 1987 a difference that increased to 22 0 by 1993 using 1987 93 data from mexico s national urban employment survey the authors study the role of occupational attainment in this wage differential most of the 1987 93 increase in the gender log monthly earnings gap they find can be explained by relative chnges in human capital endowments wage coefficient changes would have slightly reduced the gap all else equal the increasing male female earnings differential was tempered by a substantial decline in gender differences in occupational attainment from 1987 to 1993 most of the male female differences in earnings in both 1987 and 1993 can be explained by differences in rewards to individual endowments rather than gender differences in endowments

the collapse of purchasing power parities during the 1970 s one of the striking facts concerning the relationship beiveen prices and exchange rates during the 1970 s has been the dismal performance of the predictions of the simple versions of the purchasing power parity doctrine ppp that doctrine in its absolute version states that the equilibrium exchange rate between domestic and foreign currencies equals the ratio of domestic to foreign price levels the relative version of the doctrine relates equilibrium changes in exchange rates to changes in the ratio of domestic to foreign prices during the 1970 s short run changes in exchange rates bore little relationship to short run differentials in national inflation rates and frequently divergences from purchasing power parities have been cumulative this paper reviews and analyzes the empirical record of exchange rates and prices during the 1970 s and the analysis is based on the experience of the dollar pound the dollar frecch franc and the dollar dm exchange rates section 2 presents the evidence on ppp during the 1970 s and contrasts it with the evidence from the 1920 s a period during which the doctrine held up reasonably well this analysis is relevant for assessing whether the flexible exchange rate system was successful in providing national economies with an added degree of insulation from foreign shocks and whether it provided policymakers with an added instrument for the conduct of macroeconomic policy the evidence regarding devia tions from purchasing power parities is also relevant for determining whether there is a case for managed float section 3 attempts to explain what went wrong with

an empirical examination of long run purchasing power parity as theory of international commodity arbitrage an empirical analysis of long run purchasing power parity ppp as a theory of international commodity arbitrage between uk and us prices and the sterling us dollar exchange rate for the period 1975 1980 is presented econometric techniques concerning the cointegration of economic time series are applied to a sample of 35 manufactured commodities which in 1977 constituted approximately a quarter of the net output of all manufacturing industry in great britain our results are extremely unfavourable to the ppp hypothesis as a stable long run proportionality between exchange rates and disaggregated prices

does sample selection bias affect the effect of family background on the returns to schooling evidence from korea this article examines the effect of family background on the returns to schooling in korea in doing so sample selection bias is controlled as the probability of being employed is affected by the schooling of family members the results of this study are different from previous studies which did not consider sample selection bias while the effect of family background on the returns to schooling was obvious in previous studies it is weakened with the control of sample selection bias this phenomenon is particularly strong for the wife moreover controlling sample selection bias increases the downward bias due to measurement error thus it is concluded from these findings that sample selection bias should be controlled to accurately estimate the effect of family background on the returns to schooling

productive government expenditures and long run growth the purpose of this paper is to review some of the recent developments in endogenous growth models specifically our focus is on the growth effects of productive government spending in dynamic general equilibrium models we use a simple overlapping generations model as our basic framework and illustrate the role of taxes and spending we then examine several related issues nonrivalry in publicly provided goods existence and uniqueness of competitive equilibrium endogenous public policy ways of financing public expenditures composition of publicly provided goods and services and private alternatives finally we review some empirical results related to output elasticity of public capital and educational expenditures

returns to education a further international update and implications this paper updates evidence on the returns to investment in education by adding estimates for new countries and refining existing estimates to bring the total number of country cases to over 60 the new cross country evidence confirms and reinforces earlier patterns namely that returns are highest for primary education the general curricula the education of women and countries with the lowest per capita income the findings have important implications for directing future investment in education which for efficiency and equity purposes should concentrate on these priority areas

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

female labor force participation in developing and developed countries consideration of the informal sector t he steady increase in the labor force participation of married women in the united states over the last few decades has stimulated considerable interest in the economic analysis of a woman s decision to work pioneering work by mincer 1962 and cain 1966 has served as a theoretical and empirical foundation for numerous studies of female labor force participation this research typically treats a woman s current labor force status measured as a dummy variable for the individual and as a rate for the population as a measure of labor supply which depends upon economic and demographic characteristics such as female earnings male earnings non earnings income schooling work experience age number of children and so on notable examples are bowen and finegan 1969 cogan 1975 1978 gronau 1973 heckman 1974 1980 and schultz 1980 while the associated theoretical models and statistical techniques have been refined considerably especially by lewis 1972 ben porath 1973 and heckman 1974 1979 the coefficients estimated using u s data have remained reasonably robust also there is substantial agreement among micro level and aggregate results see cain 1966 and bowen and finegan 1969 for comparisons as this body of literature has grown the economic models developed within it have been implemented to analyze the labor force behavior of women in other countries however there is no consistent international pattern in the behavioral trends of the female labor force perhaps the most notable difference in the economic opportunities available to women in many other countries is that they may work in the informal sector of the labor market women may be considered economically active and may be counted as being in the labor force as they produce goods at home for market sale work on the family farm or work in a small family run business the most convenient means of categorizing workers as being in the informal sector is by their employment status following jaffe and azumi 1960 we assume that women reported as self employed or as family workers are engaged in the informal sector of the labor force almost all women in the u s labor force work as employees only 6 6 worked as self employed or family workers in 1978 given japan s advanced economic development a surprisingly large fraction 38 4 in 1978 of its female labor force comprises self employed and family workers clearly in the united states and countries with a similar distribution of the labor force by employment status the labor force participation decision may be treated as the choice to work or not to work however if individuals regard the decision to enter the labor force as an employee as being distinct from the choice to enter the labor force as a family worker then economic models of labor force participation which treat these choices as identical will incorporate a specification bias the labor force participation decision may differ between these two sectors for several reasons first the wage offers may differ by sector second while entering the informal sector may be virtually frictionless there may be fixed costs among them commuting time and child care associated with working in the formal sector third family workers may face more flexible working schedules than paid employees the latter group may be subject to contractual working hours in order to treat the labor force decisions in coiuntines with significant informal sectors this received for publication march 16 1981 revision accepted for publication september 15 1982 rutgers university this paper is a revision of work begun with my doctoral dissertation i would like to thank h gregg lewis and t dudley wallace for their suggestions and hideo okamoto for providing the data set i would also like to thank david crawford toshiaki tachibanaki two anonymous referees and the participants of the columbia labor workshop the japan economic seminar and the yale labor and population workshop for their comments remaining errors are my own this research was supported by a postdoctoral fellowship from the national institutes of health additional funding was provided by the william and flora hewlett foundation grant to the yale economic demography program i statistical abstract of the u s and japan statistical yearbook

pension design with a large informal labor market evidence from chile this article investigates the fiscal and welfare trade offs involved in designing a pension system when workers can avoid contributing by working informally using a life cycle model of labor supply and saving decisions i structurally estimate preferences and earnings opportunities in the formal and informal sectors using data on chilean households i find limited support for formal jobs rationing instead mandatory pension contributions significantly encourage informality policy experiments show that chile could lower minimum pension spending by 23 while guaranteeing the same income to retirees if the minimum pension s implicit tax rate was increased to 60

labor market integration in urban ethiopia 1994 2004 abstractan analysis of panel data on individuals in a random selection of urban households in ethiopia reveals large sustained and unexplained earnings gaps between public and private and formal and informal sectors over 1994 2004 at the same time we find first that the rate of mobility increased in the two pairs of sectors sample transitions rates grew across survey waves while state dependence in sector choice decreased second the correlation between sector choice and earnings gaps increased over the same period in particular the correlation between comparative earnings and selection into the informal sector was high throughout the survey decade and increased in magnitude over the second half of the period these results suggest that ethiopia s urban labor markets might be integrating

rethinking the economic borders of the state ownership assets and competition the paper sets out a new asset based framework for the economic borders of the state it considers how the economic borders have changed in response to major shocks notably in the 1980s and the economic concepts which lay behind these shifts notably on the microeconomic side the market and government failure framework and on the macroeconomic side the monetarist challenge to the keynesian paradigm the missing elements are the balance sheet and the treatment of assets debt and the interests of future generations particular attention is paid to utility and infrastructure assets as core public goods and to the neglect of natural capital

determinants of cross national knowledge transfer and its effect on firm innovation this study examines the determinants of international knowledge flow from a resource based perspective it evaluates the impact of cross national knowledge transfer on firm innovative performance based on 56 027 us patents owned by 53 selected firms in the us based pharmaceutical industry the results suggest that innovative performance is a curvilinear function of the international knowledge content used by a firm to innovate as hypothesized it was found that at 1 low and moderate levels of international knowledge content a firm s strategy to transfer international knowledge improves its innovative performance and at 2 higher levels of international knowledge content there are diminishing marginal returns to transferring knowledge from overseas

advertising competition and market share instability advertising can promote market power by differentiating products by establishing brand loyalty among consumers and by raising the costs of entry on the other hand advertising can be a source of valuable information to consumers that leads to an erosion in the market shares of individual sellers the empirical relationship between advertising and market share instability across industries sheds light on the competitive implications of advertising and promotional activities prior tests of this relationship rely on market share observations from the census of manufactures that are reported only every five years the present study by contrast employs a data set consisting of annual market share observations for 163 four digit manufacturing industries over the period 1978 88 the empirical results show a positive and statistically significant ceteris paribus relationship between advertising intensity and market share instability thereby lending support to the hypothesis that advertising is generally pr

salaried employment and earnings in indonesia new evidence on the selection bias this article uses household survey data to estimate the determinants of earnings in indonesia a country where nonsalaried work is widespread and earnings data are available for salaried employees only we deal with the selection bias by estimating a full information maximum likelihood fiml system of equations where selection into the labour market is modelled in a multinomial setting we find that some estimated parameters of the earnings equation differ from a binomial selection procedure by heckman 1979 in particular for those variables with the strongest impact on the selection into the different labour market statuses however the estimated returns to education are unaffected even when we deal with the endogeneity of educational attainment following duflo 2001 overall our findings show that the choice of the selection rule affects the estimates of the earnings determinants in the indonesian labour market

informal employment in developing countries opportunity or last resort there is an ongoing debate among researchers and policy makers whether informal sector employment is a result of competitive market forces or labor market segmentation more recently it has been argued that none of the two theories sufficiently explains informal employment but that the informal sector shows a heterogenous structure for some workers the informal sector is an attractive employment opportunity whereas for others rationed out of the formal sector the informal sector is a strategy of last resort to test the empirical relevance of this hypothesis we formulate an econometric model which allows for several unobserved segments within the informal sector and apply it to the urban labor market in cote d ivoire

foreign competition domestic knowledge base and innovation activities evidence from chinese high tech industries using panel data analysis for a sample of chinese high technology industries from 1998 to 2008 this study examines how industry characteristics affect industry innovation activities differing from existing studies our research considers the impact of foreign competition on innovation activities at industry level in a large emerging economy the results indicate that the intensity of competition from foreign invested enterprises fies and domestic skill intensity affect industry buy and make activities foreign competition is positively associated with the intensity of buy activity but negatively affects the intensity of make activity further the findings show that domestic skill intensity weakens the impact of foreign competitive pressure on innovation activities our empirical evidence has important policy implications

international trade performance and concentration in british industry this paper reports the results of a cross sectional analysis for 97 industries at the minimum list heading level of their international trading performance 1970 77 and the influence of industrial structure on this it is shown that on average import penetration increased faster than the export ratio for the industries analysed investigation of the relationship between industrial concentration and international trade suggest that in the majority of the analyses especially where the relation between prior concentration change and subsequent with a performance was concerned higher or increasing levels of concentration were associated with a weaker international trade performance on the basis of this it is argued that more attention needs to be paid to international trade as a performance rather than merely a structural phenomenon in industry the reasons for the relatively disappointing performance need to be investigated in more detail the risk of a decline in internaional trade performance needs to

contracts the trade account and deviations from purchasing power parity in equilibrium a hallmark of the recent monetary analysis of exchange rate determination has been the assumption of purchasing power parity p p p it can be argued that this is an arbitrage relationship in the context of a one output world in any case considerable advance has been made by analyzing international finance issues under this assumption on the other hand it is not innocuous as has been demonstrated by isard 12 and richardson 17 for example p p p does not in fact hold at least in the short run magee 16 argues that observed deviations from p p p do not imply market inefficiency because the presence of contracts in international trade implies that ex ante profit opportunities can be eliminated through arbitrage and yet p p p fail to hold in his context the deviations are spurious and therefore if taken seriously can lead to erroneous policy measures on for example dumping he assumes an exogeneous stochastic process for the exchange rate and so does not discuss the implications of contracting for equilibrium market prices harris and purvis 11 derive equilibrium market prices on the assumption of exogenous deviations from p p p and do not explicitly model the origin of these deviations in the present paper a contrast is drawn between two polar models the first is a standard stochastic equilibrium in a small open economy in which arbitrage ensures

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

lower and upper bounds of returns to schooling an exercise in iv estimation with different instruments abstract several recent studies based on exogenous sources of variation in educational outcomes show iv estimates of returns to schooling that are substantially higher than the corresponding ols estimates card 1995a earnings schooling and ability revisited research in labor economics 14 23 48 suggests that these results are explained by the existence of heterogenity in individual returns and by the fact that these studies are based on instruments that influence only the educational decision of individuals with high marginal returns due to either liquidity constraints or to high ability this conclusion is consistent with the local average treatment effect late interpretation of iv imbens and angrist 1994 identification and estimation of local average treatment effects econometrica 62 467 475 according to which iv identifies only the average returns of those who comply with the assignment to treatment mechanism implied by the instrument we show evidence for germany suggesting that returns to schooling are heterogeneous instruments matter and the late interpretation of iv makes sense with an appropriate choice of instruments we also show how iv can be used to approximate the range of variations of returns to schooling in germany

mobility and the return to education testing a roy model with multiple markets self selected migration presents one potential explanation for why observed returns to a college education in local labor markets vary widely even though u s workers are highly mobile to assess the impact of self selection on estimated returns this paper first develops a roy model of mobility and earnings where workers choose in which of the 50 states plus the district of columbia to live and work available estimation methods are either infeasible for a selection model with so many alternatives or place potentially severe restrictions on earnings and the selection process this paper develops an alternative econometric methodology that combines lee s 1983 parametric maximum order statistic approach to reduce the dimensionality of the error terms with more recent work on semiparametric estimation of selection models e g ahn and powell 1993 the resulting semiparametric correction is easy to implement and can be adapted to a variety of other polychotomous choice problems the empirical work which uses 1990 u s census data confirms the role of comparative advantage in mobility decisions the results suggest that self selection of higher educated individuals to states with higher returns to education generally leads to upward biases in ols estimates of the returns to education in state specific labor markets while the estimated returns to a college education are significantly biased correcting for the bias does not narrow the range of returns across states consistent with the finding that the corrected return to a college education differs across the u s the relative state to state migration flows of college versus high school educated individuals respond strongly to differences in the return to education and amenities across states

import share under international oligopoly with differentiated products japanese imports in u s manufacturing this paper seeks to identify the determinants of the japanese impor t share in the u s market from the assumptions of international oligopoly and internationally differentiated products a theoretical model is developed where import share is considered as a cournot nash equilibrium the relative position of the reaction functions is determined by the previous commitments of both domestic and foreign firms on advertising r d and tangible investment as well as by artificial and natural trade barriers using a sample of twenty four three digit import competing u s industries matched to japanese industries the empirical analysis provides evidence supporting the model s predictions that the relative strategic expenditures and market structures of both partners explain the japanese import share in u s markets copyright 1988 by mit press

caste discrimination and transaction costs in the labor market evidence from rural north india abstract this paper is an empirical attempt to quantify caste based discrimination in the labor market using household data taken from rural north india in the regression analysis transaction costs associated with entry into the labor market and reservation wages are estimated simultaneously along with market wages the estimation results provide evidence of the existence of transaction costs in the labor market and discrimination against backward classes with regard to access to regular employment in line with previous studies the results suggest that the achievements of india s reservation policy so far have at best been limited in addition a comparison between the estimates from the model employed in this paper and conventional reduced form approaches shows that discrimination in labor market entry is likely to be underestimated in the conventional reduced form approaches

informal employment in developing economies multiple heterogeneity abstractthis paper contributes to the literature on the nature of informal employment in developing economies drawing on the model with essential heterogeneity it offers a list of scenarios describing the behavioural patterns which informal workers follow the list nests not only classical patterns of a rationed formal sector versus an integrated labour market but also different patterns of rationing using non parametric techniques and data from a few african economies with different levels of development the paper proposes empirical case studies fitting various informality schemes developing economies show disparate patterns of allocation of workers and various patterns of rationing

human capital and earnings distribution in a developing country the case of prerevolutionary nicaragua this article examines how different patterns of human capital investments affect household earning and its major components in rural and urban areas of developing countries 1865 women aged 15 45 in the following 3 areas of prerevolutionary nicaragua supply data the central metropolis other urban areas and rural areas other urban area households have the highest average total income central metropolis households have the next highest and rural areas have the lowest urbanization is positively associated with both mean level of total earnings and with total income the authors examine 5 human capital variables womens schooling mens schooling womens health mens health and average household nutrition another variable cumulative work experience became apparent during modeling for women schooling increases labor force participation probability in urban but not rural areas nutrition has a positive impact in all 3 regions and past work experience has a significant impact health status has no effect standard human capital variables do not differ significantly between the central metropolis and other areas but sharply contrast between urban and rural areas for men there is less potential for increasing labor force participation through human capital investment although past work experience schooling and nutrition show significant effects the authors test 10 simulations of hypothetical changes in human capital distributions which involve increasing education improving nutritional status and improving health 4 conclusions are drawn 1 since changes from human capital variables on regional earnings distributions cannot be discerned from individual relations simulation is a useful tool for investigation 2 estimates of the gains toward distributional goals are needed compared to other investments 3 directing policies toward the target group is more cost effective than general measures and 4 policies should be targeted for households low in the overall distribution not just the poorest households

lead markets country specific drivers of the global diffusion of innovations abstract globally successful innovations have commonly been preferred first in one country or region before being adopted internationally countries that first adopt an internally successful innovation can be described as lead markets this paper presents the lead market concept of developing global innovations the lead role of a market is discussed first theoretically and then by use of a system of five country specific factors demand advantages price advantages export advantages transfer advantages and market structure advantages the applicability of this system of lead market factors is then evaluated in a detailed case study of the cellular mobile telephone industry it is finally suggested that companies can harness lead markets for the development of global innovations by developing and refining innovations in close interaction with the local environment of a lead market a company can focus on a narrow range of preferences and feedback lowering the risk of being locked into idiosyncratic environments and generate true global innovations a method for identifying potential lead markets is briefly discussed

demand side and supply side explanations for barriers to labor market mobility in developing countries the case of guatemala the hypothesis of labor market segmentation is based on the existence of barriers to mobility between jobs because of these barriers wages of workers with similar characteristics are different from wages that would result from competition though the labor market segmentation hypothesis concerns mobility and access there have been few direct tests of the existence of restricted mobility in the labor market rather tests of labor market segmentation have focused on the presumed effects of restricted mobility in particular the presence of different reward structures across sectors is viewed as support for the segmentation hypothesis as a result much of the literature has concentrated on the appropriate comparison of the wages of workers by including controls for observable and unobservable characteristics

purchasing power parity as a theory of international arbitrage in manufactured goods an empirical view of uk us prices in the 1970s this study treats purchasing power parity as a theory of arbitrage and seeks to test for its applicability at a disaggregated level evidence is found to suggest that arbitrage in individual markets cannot be easily aggregated due to different a adjustment periods across industries even at a disaggregated level the evidence does not suggest a long run arbitrage process of the type implied by relative purchasing power parity moreover the length of time which industries take to adjust to changes in foreign prices and the exchange rate is found to be related both to the domestic competitive environment and the extent to which the particular good is traded

competing at home to win abroad evidence from japanese industry the study explores the influence of domestic competition on international trade performance using data from a broad sample of japanese industries domestic rivalry is measured directly using market share instability rather than employing structural variables such as seller concentration we find robust evidence that domestic rivalry has a positive and significant relationship with trade performance measured by world export share particularly when r d intensity reveals opportunities for dynamic improvement and innovation conversely trade protection reduces export performance these findings support the view that local competition not monopoly collusion or a sheltered home market pressures dynamic improvement that leads to international competitiveness

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

educational attainment and earnings determination in colombia the expansion of the education sector in developing countries since the mid 1950s is certainly impressive between 1950 and 1980 primary and secondary enrollment ratios in many of these countries tripled or quadrupled and the educational gap with respect to developed countries narrowed although most social planners and politicians would argue that there is still a long way to go before socially optimal levels of education are attained it is also commonly acknowledged that there is an increasing need for a more careful and systematic evaluation of educational policies and by implication public funding priorities 2 although there is the question of whether all types of education should be considered equally much of the work in the evaluation process has been devoted to the production of estimates of the social and private rates of return to schooling 3 most of the early research in this area ignored the effects of educational quality heterogeneous individual abilities and other types of selection bias issues these so called first generation models produced relatively high rates of return to additional years of education from 15 to 30 depending on the country and statistical methodology employed 4 these estimates led to a form of consensus that education was a high priority item in government budget planning there is only limited evidence of how rates of return have fared subsequent to the growth of the education sector in the case of colombia however g psacharopoulos noted that the rate of return to education fell from about 20 in the early sixties to below 10 by 1979 5 during the eighties a number of second generation studies

r d rivalry industrial policy and u s japanese trade the authors examine how the strategic aspect of japanese research and development expenditures and industrial policies affected u s japanese bilateral trade during the late 1970s and investigate which component of r d expenditures on process innovation product quality improvements new products and new technology or technology transfer proved to be most effective they find that while japanese r d expenditures have generally promoted japan s trade advantage certain components of r d have proved more effective than other the depreciation subsidy and special status with the ministry of international trade and industry is positively related to the japanese trade performance while legal cartelization status has not had any apparent effect copyright 1988 by mit press

scaling the commanding heights of public enterprise economics there is a new orthodoxy in the economics of the public sector that has been promoted by privatization and for which ownership as such is essentially seen as irrelevant as compared to conditions of competition and regulation this is shown to depend upon an illegitimate and static view of the beneficial effects of competition a questionable distinction between natural and artificial monopoly a false history of the motives for and the performance of the nationalized industries a reduction of industrial to competition policy and a failure to examine intersectoral linkages rectifying these deficiencies suggests an alternative analytical and more favorable stance on public ownership copyright 1990 by oxford university press

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

the persistence of market leadership evidence from japan this article explores the persistence of market leadership in japanese manufacturing industries over the period 1975 2004 by applying survival data techniques we examine how long market leadership persists and how the duration of market leadership varies according to industry specific characteristics our findings indicate that market leaders maintain their leadership positions for on average 20 years from 1975 in japanese manufacturing industries we provide evidence that market leadership tends to persist in capital intensive and legally cartelized industries whereas it is less likely to persist in demand volatile r d intensive and import intensive industries copyright 2009 the author 2009 published by oxford university press on behalf of associazione icc all rights reserved oxford university press

the performance of industrial sector voluntary climate programs climate wise and 1605 b abstract corporate voluntary climate programs have had limited evaluation the self selection of participants an essential element of such initiatives poses challenges to researchers because the decision to participate may not be random and may be correlated with outcomes this study aims to gage the environmental effectiveness of the industrial sector elements of two early voluntary climate change programs with established track records the u s environmental protection agency s climate wise and the u s department of energy s voluntary reporting of greenhouse gases program 1605 b particular attention is paid to the participation decision and how various assumptions affect estimates of program outcomes using propensity score matching methods applied to plant level census data overall the effects are modest reductions in fuel and electricity expenditures are no more than 10 percent and probably less than 5 percent virtually no evidence suggests either program has a statistically significant effect on fuel costs some evidence indicates that participation in climate wise led to a 3 5 percent increase in electricity costs that vanished after two years stronger evidence suggests that participation in 1605 b led to a 4 8 percent decrease in electricity costs that persisted for at least three years these results suggest that while voluntary programs can play some role in addressing climate change they are unlikely to bring about the kinds of steep reductions called for in the current debate

schooling and labor market consequences of school construction in indonesia evidence from an unusual policy experiment between 1973 and 1978 the indonesian government engaged in one of the largest school construction programs on record combining differences across regions in the number of schools constructed with differences across cohorts induced by the timing of the program suggests that each primary school constructed per 1 000 children led to an average increase of 0 12 to 0 19 years of education as well as a 1 5 to 2 7 percent increase in wages this implies estimates of economic returns to education ranging from 6 8 to 10 6 percent

thirty years after water privatization is the english model the envy of the world the paper considers whether water privatization 30 years ago has delivered the promised superior performance to nationalization which remains the dominant model in europe the paper sets out the arguments at privatization in particular in relation to efficiency the managerial incentives the role of private sector balance sheets in facilitating investment and the impacts on the cost of capital alternative explanations of relative performance notably the regulation model adopted are highlighted and the paper concludes by outlining an alternative model of water regulation which better marries up public responsibilities and private incentives

what determines success examining the human financial and social capital of jamaican microentrepreneurs abstract this research examines the performance of 215 informal microenterprises in jamaica studying the influence of human capital social capital and financial capital of the owners on their business profitability understanding the importance of particular relationships that result in successful micro businesses is important for a number of reasons first among many developing countries the growth of microenterprise provides the most visibly vibrant and growing economic activity although considerable effort and resources are being directed toward microenterprise promotion schemes empirical research on the subject is quite limited second economies in developing countries mirror many of the social and institutional problems existent in urban economically disadvantaged areas of the united states and other developed countries for these areas microenterprise may be an essential component of urban renewal and community development this study helps in identifying important characteristics of social and individual attributes that may be relevant to those attempting to strengthen this subsector finally this study seeks to provide insight into a dimension of microbusiness research for which there are limited data specifically the role that social capital plays among practicing entrepreneurs and owners this research found that different structural environments even within a singular and small economy may considerably alter the rates of return to human social and financial capital as a result the analysis of enterprises includes segmentation according to both the usage or not of employees and the sophistication of the technologies used several factors were determined to enhance the profitability of the businesses in all categories vocational training for example demonstrated consistently strong and positive effects mother s high occupational status a proxy for socioeconomic status and years of experience in the business were also consistently positive and strongly associated with increasing profits although additional starting capital played an important role for both the businesses with and without employees increasing amounts failed to differentiate the success of those firms that were already operating in the higher technological tier obtaining a small business loan acted in a similar manner enhancing the profitability of all firms except those segmented into a high technological tier one interpretation of this finding is that the role of technological choice is extremely important and appears to dwarf that of varying amounts of starting capital social capital as operationalized by frequent church attendance and marital status of the owner was found generally to increase the profitability of the business the data demonstrate that social networks play an important role in the success of these businesses and that conditions in the highest tier utilize social capital in a somewhat unique manner

further evidence on competition in the us grain export trade this study analyzes the relationship between export market structure and the pricing behavior of u s grain exporting firms a generalized cournot model is estimated by two stage least squares using pooled data sets for u s wheat and corn exports the cross sectional units correspond to foreign country destinations discriminatory export pricing behavior was found to be significantly related to export seller concentration u s market share total export volume and import market size yet the estimated coefficients linking these market structure variables to the export price markup were relatively small in magnitude suggesting little quantitative impact from market power copyright 1994 by blackwell publishing ltd

the quality of schooling quantity alone is misleading although much research discusses the quantity of schooling as an effective impact on productivity and earnings most such research leaves out the idea of the quality of schooling which may cause biases in the estimated returns to schooling this paper consequently attempts to extend the standard mincerian approach to incorporate school quality as well as quantity it demonstrates how exclusion of quality in the standard procedure may cause biases in the estimated returns to years of schooling probably in the upward direction the paper explores the implications of this extension of the standard model for the case of young brazilian males it shows that the estimate of the private return to years of schooling using the preferred quality inclusive specification is only one half the estimate using the standard procedure indicating substantial upward bias in the standard estimates it further outlines a method for estimating a social return to quality and finds that it exceeds substantially the social return to quantity the paper then shows why this in turn suggests there may be an equity productivity trade off in schooling investments

competition in japan japan registered a remarkable 6 5 percent rate of economic growth from 1955 to 1990 catching up with high income western countries in its level of economic development during the 1950s 1960s 1970s and into the 1980s japan s share of world exports rose dramatically from 2 9 percent in 1960 to 6 1 percent in 1970 8 2 percent in 1980 and a peak of 9 8 percent in 1985 porter takeuchi and sakakibara 2000 japanese firms were increasingly successful internationally in large visible industries such as automobiles semiconductors and consumer electronics the striking economic success of japan was widely attributed to a set of economic institutions and policies that encouraged collaboration and limited competition the japanese case then called into question many of the bedrock assumptions of competition thinking it seemed to show that there was a different path to economic prosperity this article begins by examining competition in japan and the supporting policies and institutions during the twentieth century many factors seem to suggest that competition in japan has been less intense but there is an awkward complication the empirical evidence about the intensity of competition in japanese industry does not support the conclusion the story clearly is more complicated we seek to reconcile the apparent differences between policy and institutional circumstances and the empirical evidence by examining the types of competition that prevail across japanese industries and the underlying causes japan indeed pursued an array of policies that limited competition but these policies were not applied throughout the economy in fact those industries in which competition

the assessment introducing competition into regulated industries the introduction of competition into utilities is currently being pursued in the many countries including the uk competition can take various forms such as competition for outputs inputs franchises and outright takeovers attention is currently focused on output competition whereby customers are being given a choice of final supplier in many industries we consider the implications of the introduction of such competition including the effects on industrial structure and contracts cross subsidies and distributional concerns and uncertainty and stranded contracts we also analyze the transitional problems encountered as competition is introduced and suggest that the uk regulators and government have in some key respects failed to define a clear and consistent policy
