factor price distortions resource allocation and growth a computable general equilibrium analysis the present paper estimates the welfare cost of both labor and capital market distortions in south korea using a computable general equilibrium model and expands on earlier studies by distinguishing autonomous differentials from distortions in accounting for differences in sectoral wages and returns to capital the results of this paper cast doubt on the generality of the proposition on the sensitivity of economic efficiency to market distortions our results show that removing labor market distortions would increase output by less than 1 of the base year gdp even when capital market distortions are also removed the gdp increases only by 3 2 and welfare by 5 6 the study also examines a consequence of capital market distortions which suggests that distortions may lead to more rapid capital formation and higher concentration of capital stock given the industrial policy configuration in korea we find that financial incentives had more distorting effects than fiscal incentives copyright 1995 by mit press

capital utilization economies of scale and technical change in the growth of total factor productivity an explanation of south korean manufacturing growth abstract this paper presents a method of interpreting the growth of total factor productivity directly linking the productivity growth to key parameters of a specific cost function it shows that the productivity index can be decomposed into effects due to a technical change b non constant returns to scale and c change in capital utilization the decomposition framework was applied to data on south korean manufacturing during the 1961 1980 period in south korean manufacturing the total factor productivity was found to have grown at 3 per annum scale economies contributed about 38 of the growth of tfp the technical change 45 and the change in the capital utilization rate 17 the results of this study support of the view that for growing less developed economies the growth in capital utilization rate is a source of growth in total productivity that is too significant to be ignored

economic growth and productivity a case study of south korea the economic performance that south korea has achieved over the past quarter century is often likened to a miracle recently much interest has been expressed in the driving forces behind the korean economic transformation using the valueadded measure of output christiansen and cummings have shown that technology measured by tfp accounts for about 43 of korean economic growth between 1960 and 1973 this figure is considerably high compared with recent major studies on japanese and singaporean economic growth we found that the value added framework is not appropriate for the description of the structure of the korean economy and re examined the sources of korean economic growth using the gross output framework surprisingly it has been discovered that only 7 of real output growth in the manufacturing sector during the 1962 1981 period is attributable to technological progress these findings parallel those for the japanese and singapore economies

efficient education subsidization and the pay as you use principle abstract we investigate whether the pay as you use principle of public finance should apply to education subsidization for children to internalize human capital externalities in an intergenerational model with endogenous fertility leisure and accumulations of human and physical capital we characterize social optimality concerning physical and human capital accumulation leisure labor and fertility to guide the design of efficient education subsidization we show that efficient education subsidization requires future generations benefitting from it pay for it when fertility and leisure are endogenous namely the government should uphold the pay as you use principle to subsidize children s education by deficit and repay the debt by future taxes

the political intergenerational welfare state abstract using a three period overlapping generations economy framework we characterize an intergenerational welfare state with endogenous education and pension under voting we show that although politically establishing pay as you go payg social security in isolation in a dynamically efficient economy will always reduce the capital investment and therefore the social welfare as expected in contrast politically implementing education pension policy package instead can improve both human and physical capital accumulation and social welfare over laissez faire however for this the political influence of the old has to be small thus limiting the size of the payg social security program

comparative productivity of korean manufacturing 1967 1987 this paper compares productivity levels in south korean manufacturing with those in the usa for 13 manufacturing branches the comparison is based on specific industry of origin purchasing power parities value added per hour worked in korean manufacturing rose from only 4 5 percent of the us level in 1967 to more than 18 percent in 1987 total factor productivity rose from only 9 percent in 1967 to 26 percent of the us level in 1987 at a more detailed level especially the leather metals and machinery industries have reached high productivity levels some of which approach levels in european manufacturing the considerable labour productivity gap between korea and the united states can partly be explained by capital intensity structural effects size effects and levels of education

the structure of production in south korea s manufacturing sector abstract this paper estimates a model of producer behavior for south korean manufacturing that simultaneously identifies substitution elasticities and scale economies a non homothetic translog function is employed which takes on various other functional forms i e cobb douglas homothetic homogeneous as special or limiting cases four significant conclusions are a there is potential scale economies in each subsector of south korean manufacturing b the substitutabilities between factor inputs are relatively low c factor demands are price elastic d the scale economies are correlated with the factor intensity

equity and educational performance in this paper we review the main issues under discussion in the field of economics of education with a special focus on latin america we seek to organize the debate about educational policies by showing how these policies respond to different models based on different assumptions and hypotheses about how the educational system functions methodological and informational problems make it difficult to test the validity of different policies this would explain the enormous number of studies in the field that conclude with conflicting policy prescriptions we also use data from chile to analyze the importance of the school in educational outcome and to explore the heterogeneous impacts of student and school characteristics on educational achievement the results obtained allow us to conclude that the school plays a very important role in explaining educational achievement we also find that low income students stand to benefit the most from attending a private school however this conclusion is valid for a marginal analysis and does not necessarily apply to a massive reallocation of students among schools

friedman rule in a model with endogenous growth and cash in advance constraint this paper introduces money into an overlapping generations model with endogenous growth the model due to docquier et al 2007 exhibits a positive intergenerational externality which precludes its laissez fair equilibrium to be optimal even if the government can control the level of physical capital and set it to satisfy the modified golden rule the main message of the paper is that as long as the modified golden rule is attained friedman rule is optimal the result holds regardless of the ability of the government to internalize the externality and control the level of human capital other results include i violation of friedman rule for a different second best environment wherein human capital accumulation is controlled but not physical capital accumulation ii existence of a negative relationship between money growth rate and the economy s endogenous growth rate and iii non uniqueness of friedman rule

socially optimal social security and education subsidization in a dynastic model with human capital externalities fertility and endogenous growth abstract this paper considers socially optimal government policies in a dynastic family model with physical capital human capital endogenous fertility and positive spillovers from average human capital such spillovers reduce human capital investment but raise fertility from their social optimum we first characterize the social optimum with a non convex feasible set due to the quantity quality tradeoff concerning children we then show that social security and education subsidization together financed by labor income taxes can fully eliminate the efficiency losses of the spillovers and achieve the social optimum under plausible conditions however none of the policies can do so alone

why have urban poverty and income inequality increased so much argentina 1991 2001 abstract this article analyzes the trends in income inequality and poverty among argentine households during the nineties we assess the effect of changes in labor force participation unemployment educational levels and returns to individual characteristics on income inequality and poverty by using a microsimulation approach we found that unemployment accounts for a large part of the increase in income inequality and poverty experienced in the past decade changes in labor force participation had an equalizing effect over the whole period while changes in the returns to workers sociodemographic characteristics could be associated with a small increase in income inequality with respect to poverty unemployment affected negatively the proportion of households below the poverty line amplified the poverty gap and increased the severity of poverty in contrast changes in labor force participation are associated with a reduction in the poverty rate

rising inequality in mexico household characteristics and regional effects we use an empirical framework to identify the contributions of microeconomic factors to the sharp rise in household per capita income inequality in mexico between 1984 and 1994 results indicate that changes in returns to household characteristics in particular changes in returns to education are responsible for about half of the increase in the gini coefficient the deteriorating conditions in rural areas relative to the urban areas and of the southern region relative to other regions account for another fourth of the increase in the gini

the intergenerational state education and pensions allocation is inefficient when generations overlap this failure can be mitigated by properly designed social arrangements we show that public financing of education and public pensions can be designed to implement an intergenerational transfer scheme supporting the complete market allocation neither the public financing of education nor the pension scheme we consider resemble standard ones in our mechanism via the public education system the young borrow from the middle aged to invest in human capital they pay back the debt via a social security tax the proceedings of which finance pension payments when the complete market allocation is achieved the rate of return implicit in this borrowinglending scheme should equal the market rate of return

linking consumption externalities with optimal accumulation of human and physical capital and intergenerational transfers abstract this paper opens a new perspective from which one can explain the presence of government intervention in education even in the absence of human capital externality it argues that consumption externalities can provide rationale for government intervention in education within the context of overlapping generations economy it has also been shown that competitive equilibrium either underaccumulates both physical and human capital or overaccumulates both thus the result rules out the possibility of competitive equilibrium deviating from the social optimum in its allocation of physical and human capital in opposite directions immediate policy issues have also been discussed

export performance and productivity growth the case of taiwan the hypothesis that rapid growth of exports accelerates economic growth has been widely discussed and tested the empirical evidence that supports the hypothesis includes studies by m michaely b balassa p heller and r porter w tyler g feder r kavoussi and r ram using macrodata and m nishimizu and s robinson using two digit industry level data feder found that exports contribute to economic growth because the export sector is not only more productive than the nonexport sector but also generates some external effects that enhance the productivity of the nonexport sector as exports expand both the resource reallocation effect and externality effect lead to an economy wide productivity increase nishimizu and robinson also found the existence of a significant correlation between productivity growth and export expansion on a theoretical level there are at least two interpretations of the correlation between productivity growth and export expansion one stresses scale economies the other stresses competitive forces the scale economies argument emphasizes the benefits that can be derived by means of expanding the scale of operations in the case of countries whose domestic markets are small in size exporting becomes an essential part of achieving scale economies j bhagwati considered scale economies to be a plausible explanation for the superiority of the export promotion trade strategy as opposed to the import substitution trade strategy but warned against the lack of convincing evidence 2 the study by j kwon on the korean manufacturing industry also found that scale economies are a main factor contributing to total fac

ageing government budgets retirement and growth we analyze the short and long run effects of demographic ageing increased longevity and reduced fertility on per capita growth the olg model captures direct effects working through adjustments in the savings rate labor supply and capital deepening and indirect effects working through changes of taxes government spending components and the retirement age in politico economic equilibrium growth is driven by capital accumulation and productivity increases fueled by public investment the closed form solutions of the model predict taxation and the retirement age in oecd economies to increase in response to demographic ageing and per capita growth to accelerate if the retirement age were held constant the growth rate in politico economic equilibrium would essentially remain unchanged due to a surge of social security transfers and crowding out of public investment

the cross sectional inter industry structure of capital utilization in a developing economy the case of s korean manufacturing t he literature on capital utilization has experienced a remarkable growth of late in particular implications of a model of optimal capital utilization put forth by kim and winston 1974 have been shown to be consistent with empirical findings 1 on inter country crosssectional sectoral rates of capital utilization kim 1969 mason and sakong 1971 and winston 1971b and 2 on intra country timetrend rates of capital utilization kim and kwon 1977 as a sequel to such recent developments this paper proposes to show an implication of the kim winston model in the context of an intra country cross sectional inter industry structure of capital utilization and then to test this implication against cross sectional data from s korean manufacturing industries

input measurement and productivity growth in japanese and u s manufacturing in their article in this review j r norsworthy and david h malmquist 1983 have presented interesting comparisons of productivity growth in the japanese and u s manufacturing sectors their paper starts with the discussion of whether the conventional value added or gnp measurement of output is an appropriate framework for productivity analysis some confusion frequently arises as to whether a production function should be structured on the basis of gross output or value added output separability is a pivotal concept in the analysis of production structures especially in relation to the existence of a real value added aggregate it is well known that there are two types of separability which pertain to the existence of a real value added function weak local separability and strong partial separability the practical advantage of distinguishing these two different forms of separability is that the double deflation method in conventional gnp accounting is justified only when strong partial separability holds using the approximate separability tests of michael denny and melvyn fuss 1977 norsworthy and malmquist have shown that a value added aggregate does not exist in either u s or japanese manufacturing and they conclude that the appropriate output measure for joint investigation of both countries for purposes of productivity analysis is gross output p 953 the purpose of this comment is to indicate some deficiencies in norsworthy and malmquist s analysis in particular it will be demonstrated that the conditions for weak local and strong partial separability in norsworthy and malmquist s paper are incorrectly formulated and as a consequence their findings may not be used as conclusive evidence that a gross output measure is an appropriate basis for the analysis of capital labor substitutability and productivity growth in japan and the united states

factor substitution approach to testing the time variations in production the case of taiwan s manufacturing this paper is devoted to studying the time variations in the series of elasticities of factor substitution which in a sense manifests changes in production technology and structure a lkm translog cost function model is used to estimate the allen uzawa elasticities of substitution for taiwan s manufacturing sector in 1965 91 the variations are analysed using a regression model which incorporates the linear spline setting and income variable empirical results indicate that obvious structural breaks in the elasticity series conform to major exogenous disturbances such as worldwide energy crises and developmental policy changes

rapid economic growth with increasing returns to scale and little or no productivity growth total factor productivities for 28 korean manufacturing sectors were estimated jointly with markups scale economies and the capacity utilization rate using the short run generalized leontief cost function concavity conditions necessary for the cost function to be well behaved and consistent with a firm s optimizing behavior were imposed on the estimation by way of bayesian inference the study finds 1 the superiority of the short run equilibrium model over the long run model and of the short run generalized leontief cost function over the translog cost function 2 market imperfection 3 the existence of scale economies and 4 biases in the traditional tfp measures the study also suggests that a rapid growth of output is possible with negative tfp growth copyright 1995 by mit press

optimal accumulation in an endogenous growth setting with human capital this paper considers a three overlapping generations model of endogenous growth wherein human capital is the engine of growth it first contrasts the laissez faire and the optimal solutions three possible accumulation regimes are distinguished then it discusses a standard set of tax transfer instruments that allow for decentralization of the social optimum within the limits of our model the rationale for the standard pattern of intergenerational transfers the working aged financing the education of the young and the pension of the old is seriously questioned on pure efficiency grounds the case for generous public pensions is rather weak

school subsidies for the poor evaluating the mexican progresa poverty program abstract this paper evaluates how the progresa program which provides poor mothers in rural mexico with education grants has affected enrollment poor children who reside in communities randomly selected to participate in the initial phase of the progresa are compared to those who reside in other control communities pre program comparisons check the randomized design and double difference estimators of the program s effect on the treated are calculated by grade and sex probit models are also estimated for the probability that a child is enrolled controlling for additional characteristics of the child their parents local schools and community and for sample attrition to evaluate the sensitivity of the program estimates these estimates of program short run effects on enrollment are extrapolated to the lifetime schooling and the earnings of adults to approximate the internal rate of return on the public schooling subsidies as they increase expected private wages

education subsidies social security and growth the implications of a demographic shock we develop a three period overlapping generations model in which individual decisions about education are the engine of growth in this setting we investigate the normative role of education subsidies and old age pensions calibrating this model on empirical data it is shown that the case for positive pension benefits is rather weak on the optimal path an important part of education subsidies should be financed by lump sum taxes on retirees we also examine how these transfers should be adjusted in the presence of a baby boom baby bust demographic shock it turns out that an appropriate policy could be to increase education when the baby boom generation is at work labor productivity will then be higher when aging peaks so that the pension bill can be financed without reducing welfare for the baby bust generations

financial deepening inequality and growth a model based quantitative evaluation we propose a coherent unified approach to the study of the linkages among economic growth financial structure and inequality bringing together disparate theoretical and empirical literature that is we show how to conduct model based quantitative research on transitional paths with analytical and numerical methods we calibrate and make tractable a prototype canonical model and take it to an application namely thailand 1976 96 an emerging market economy in a phase of economic expansion with uneven financial deepening and increasing inequality we look at the expected path generated by the model and conduct robustness experiments because the actual path of the thai economy is imagined here to be just one realization of many possible histories of the model economy we construct a covariance normalized squared error metric of closeness and find the best fit simulation we also construct a confidence region from a set of simulations and formally test the model we broadly replicate the actual data and identify anomalies robert m townsend is a professor at the university of chicago and a consultant at the federal reserve bank of chicago kenichi ueda is an economist at the international monetary fund the views expressed in this paper are those of authors and do not necessarily represent those of the frb chicago the federal reserve system or the imf we thank the national statistics office of thailand for permission to use the ses data we received helpful comments from robin brooks fabio canova marco cagetti larry christiano angus deaton paul evans jess gaspar hyeok jeong ashok mody tomoyuki nakajima hajime takizawa chris udry annette vissing jorgensen and the participants of the nber general equilibrium conference at new york university the conference honoring rolf r mantel in argentina seminars at cornell university grips hitotsubashi university ohio state university oxford university and the imf as well as the imf conference on macroeconomic policy and poverty reduction we are especially indebted to the editors and referees townsend acknowledges financial support from the nsf and nichd we thank natalia ramondo for excellent research assistance

long run determinant of korean economic growth empirical evidence from manufacturing this paper challenges the recent contrarian view that the phenomenal growth of east asian nics is fuelled mainly by the accumulation of production inputs not by tfp growth to appraise this view we investigated and re evaluated south korean manufacturing growth 1973 q1 1993 q4 using johansen s cointegrating analysis our results show that south korean manufacturing appears to have increasing returns to scale in production technology the learning by doing effect defined by lucas 1988 is empirically supported this effect appears to be observed as a long run determinant of south korean manufacturing growth consequently south korean manufacturing growth can be described by an endogenous economic growth model such as the lucas 1988 model contradicting the contrarian view

social security and endogenous growth abstract this paper examines the effects of social security on the steady state growth of per capita income in an endogenous growth model in which agents care about their own consumption the number of children and the welfare of each child it shows that an unfunded program may simulate growth by reducing fertility and increasing the ratio of human capital investment per child to per family income when bequests are positive also it may cause faster growth than funded programs especially when receipts from funded programs are independent of contributions when voluntary saving is positive funded social security is neutral if receipts are linked to contributions and most likely depresses growth if receipts are independent of contributions

the east asia challenge to neoclassical orthodoxy abstract this article reviews the east asian miracle economic growth and public policy which concludes that east asian economic success has little to do with government using criteria similar to that used in the world bank report this study shows that contrary to world bank contention industrial policies used in east asian economies have been effective non neoclassical tools for economic development with government complementing market factors by creating an environment conducive to economic growth given that japan and korea are the most representative examples of industrial policies and that the report seems to acknowledge the success of the japanese industrial policies the present study confines itself largely to a discussion of korean evidence

interpretation and measurement of capacity utilization the case of korean manufacturing this paper focuses attention on the conceptual difference between optimal ex ante and actual ex post capacity untilization cu the dynamic version of the efficient output approach to capacity untilization which this paper presents is theoretically superior to other alternative approaches our concept of optimal cu has been applied to estimate cu measures for korean manufacturing we fing that our measure of cu explains the trends and cycles in korean economy rather convincingly and that korean manufacturing has adjusted much more flexibly to market demand shocks than it has to exogenous changes in factor prices from the examination of the determinants of cu we find that while wages and material prices have positive effects on cu energy prices and capital stock have nagative effects the study also implies that overambitious government incentive policies to stimulate investment may have an adverse effect on capacity utilization

non parametric approach to dynamic efficiency a non parametric application of cointegration to production frontiers estimation of dynamic production and cost frontiers raises some basic econometric problems when the input output data are nan stationary over time methods of cointegration can be applied in such situations to identify and estimate the efficient production and cost functions the method of cointegration is here extended to the case of one sided errors and then empirically applied to the production data of the manufacturing sector for south korea in recent times

convergence of south korean productivity on west german levels 1966 1978 abstract south korean labor productivity in manufacturing converged rapidly on the productivity level in west german manufacturing during the period 1966 1978 achieving two thirds of the german level by 1978 this convergence was more rapid at the industry level than for all manufacturing the capital labor ratio and total factor productivity in south korean manufacturing also converged on west german levels during this period with the former accounting for two thirds and the latter one third of the labor productivity convergence the source of labor productivity convergence however differed greatly across industries with capital deepening the dominant source in heavy industries and total factor productivity tfp convergence the main source in light industries
