marshall s scale economies using panel data this paper estimates plant level production functions for machinery and high tech industries that allow for scale externalities from other plants in the same industry locally and from the scale or diversity of local economic activity outside the own industry the paper finds that the count of other own industry plants representing a count of local information spillover sources has strong productivity effects in high tech but not machinery industries single plant firms both benefit more from and generate greater external benefits than corporate plants given their greater reliance on external environments on dynamic externalities high tech single plant firms benefit also from the scale of past own industry activity i find little evidence of economies from the diversity or scale of local economic activity outside the own industry

variable returns to agglomeration and the effect of road traffic congestion abstract this paper investigates the links between returns to urban density productivity and road traffic congestion a generalised translog production inverse input demand function is estimated to test for the existence of variable returns to agglomeration in manufacturing construction and service industries two separate measures of urban density in which proximity is represented by straight line distance or by generalised cost are constructed and included in the translog to identify the effect of road traffic congestion the results show that for some sectors of the economy diminishing returns to urban density can set in causing the magnitude of agglomeration elasticity to fall as effective densities increase the generalised cost based measure of agglomeration produces higher elasticities because it captures both time and distance dimensions of density a comparison of spatial variance in estimates indicates that road traffic congestion plays an important role in explaining diminishing returns for the most highly urbanised locations

financial factors in economic development financial factors have been assigned strategic importance in economic development but very different factors have been isolated in the respective experiences in asia unrepressed financial markets in mobilizing saving and allocating investment have been given prominence in latin america the central question is the role of inflationary finance the scope for deficits to enhance growth and increasingly the feedback from high and unstable inflation to poor economic performance this paper reviews and contrasts the two approaches and concludes that the strong claims for the benefits of financial liberalization are not supported by evidence financial factors are important but probably only when financial instability becomes a dominant force the scope for inflationary finance is small and the risks are larger than commonly accepted when hyperinflation takes over and foreign exchange crises disrupt the price system and shorten the economic horizon to a week or a month normal economic development is suspended moreover difficult to reverse capital flight puts savings outside the home economy attention should focus on these extreme cases and explore deeper the thresholds at which financial factors become dominant and the channels through which this occurs superior growth performance in this perspective may be more a reflection of adaptability than financial deepening this abstract was borrowed from another version of this item

what went wrong with the recent reforms in the southern cone this paper describes and interprets the outcome of the reform packages in chile argentina and uruguay during 1974 83 it is shown that all three countries experienced initial success with the rescue operation from the severe macroeconomic disequilibrium at the inception of the reforms the paper then discusses the areas in which the reforms were successful and why the countries experienced boom bust cycles resulting in large increases in external indebtedness and internal financial crises the paper attributes the failure of the reforms to a combination of policy inconsistencies implementation difficulties and market frictions jointly these factors generated a sustained appreciation of the real exchange rate and a large spread between the cost of dollar denominated and peso denominated loans in turn the appreciation and interest rate difference created protracted opportunities for arbitrage that distracted firms from the business of production

agglomeration economies and industrial decentralization the wage productivity trade offs abstract this paper examines the industrial location trade offs between the productivity advantages of the metropolitan center and the lower land and the labor costs in outlying regions within the state of sao paulo brazil the results indicate that while plant productivity is enhanced by the considerable agglomeration economies existing within metropolitan sao paulo firms must pay for these benefits in high wages and land costs offsetting labor cost savings can be achieved by locating in outlying regions the evidence presented in this paper suggests that market forces may lead eventually to a spontaneous decentralization of industry

inflation bias after the euro evidence from the uk and italy this article presents an indirect approach to investigate the possible existence of measurement error bias in the harmonized index of consumer prices for the uk and italy our empirical results show that there is no significant evidence of a bias for the uk or for italy prior to the introduction of the euro since january 2002 however the inflation rate in italy has been underestimated by at least 6 percentage points

aggregate savings financial intermediation and interest rate there has been considerable controversy about the role of financial factors as determinants of savings in developing countries this paper explores the importance of two such factors namely real interest rate and financial intermediation using pooled time series cross section data a model of savings is estimated for asia latin america and for the total sample particular attention is paid to the error structure in estimation the results suggest that pooling is not justified further there is no unequivocal support for the effect of either of the two factors some qualified support is found for asia but none for latin america copyright 1987 by mit press

financial liberalization in sub saharan africa what do we know abstract beginning from the early 1980s countries in sub saharan africa embarked on financial liberalization policies with a view to reversing the ill effects of financial repression this paper provides a survey of financial liberalization in sub saharan african countries over the period 1980 to 2004 our review of empirical studies showed that financial liberalization has had diverse and contrasting effects on savings investment and economic growth most studies found a significant positive effect of financial liberalization on investment whereas its effect on savings has been largely insignificant the evidence on the effect on economic growth is inconclusive as different studies find contrasting results it is found that financial liberalization policies have not had the desired and expected results as both financial and macroeconomic variables have not improved following financial liberalization in these countries this calls for a rethinking of financial liberalization in sub saharan african countries it is important that financial liberalization is carried out in a stable macroeconomic environment in addition to this there should be a building and reform of institutions and the strengthening of prudential regulation following this financial liberalization can be embarked upon but it must be properly sequenced and not rushed

commercial bank offices and the mobilisation of private savings in selected sub saharan african countries the mobilisation of domestic savings has remained a thriving issue in discussions of ways and means of harnessing resources for development in africa this work attempts to examine the role of a deliberate policy of extending offices of banks to the rural areas in savings mobilisation efforts using ordinary least squares methods data from five african countries that have pursued this policy in recent times are examined to see if there is any significant relationship between the savings rate and their population per bank office ratio our results are consistent with the hypothesis that the extension of branch offices of banks to rural areas could help attenuate the poor savings performance in most african economies

real money balances in the production function of a developing country real money balances as a factor input in the production function of the large scale manufacturing sector in pakistan has been examined in a multi equation framework besides labor and capital real money balances turned out to be an important factor of production our results are in accordance with the pioneering work of sinai and stokes in this area

optimal financial and foreign exchange liberalization of less developed economies this paper models a typical highly inflationary less developed economy in which monetary forces are the result of three policy determinants the rate of monetary expansion the interest rate on bank deposits d and the rate of depreciation of the real exchange rate a the task confronting policy makers is to reduce the equilibrium inflation rate without undue transitional sacrifice of the growth objective we demonstrate that this optimally requires the precise coordination of all three instruments with high but declining values of d and being adopted initially and with a being modulated so as to forestall excessive capital inflows and to influence favorably the evolution of relative input prices

the variable rate of growth effect in the life cycle saving model the rate of growth in real gnp g affects the aggregate saving rate positively in life cycle saving models this rate of growth effect is invariably estimated as the coefficient of g in the saving function we show that other determinants of the saving rate influence the rate of growth effect in other words the rate of growth effect is not constant specifically the real rate of return on financial assets and the population dependency ratio determine the timing of saving over the life cycle and hence alter the rate of growth effect the dependency ratio also has an effect on the saving rate which is independent of g because it together with the foreign saving rate determines the level of saving over the life cycle

us metropolitan spatial structure and labour accessibility metropolitan areas vary widely in employment distribution and labour accessibility comparing four us metropolitan areas atlanta boston phoenix and washington dc it is found that atlanta and washington dc suffer from low labour accessibility compared with boston and phoenix moreover large suburban employment centres in atlanta and washington dc suffer from even lower accessibility than other employment centres within the same metropolitan areas or their counterparts in boston and phoenix their low labour accessibility is mainly explained by slower commuting speeds even though their residential and employment densities are modest congestion in these employment centres is severe enough to undermine accessibility the results raise questions about the effectiveness of creating large sub centres in metropolitan areas particularly creating auto oriented edge city style employment centres at highway nodes

agglomeration accessibility and productivity evidence for large metropolitan areas in the us this paper estimates the productivity gains from agglomeration economies for a sample of the largest metropolitan areas in the united states using measures of urban agglomeration based on employment density and employment accessibility the latter is a more accurate measure of economic proximity and allows testing for the spatial decay of agglomeration effects with increasing travel time we find that the productivity gains from urban agglomeration are consistent between measures with elasticity values between 0 07 and 0 10 the large majority of the productivity gains occur within the first 20 minutes and do not appear to exhibit significant nonlinearities

declining city productivity and the growth of rural regions a test of alternative explanations prior to the 1970s the u s witnessed a net flow of migrants from its nonmetropolitan to its metropolitan region since then however a dramatic reversal of this long standing tendency for people to concentrate in metropolitan places has been observed nonmetropolitan places have gained migrants largely as the result of increased outmigration from metropolitan areas an open question has been to what extent the employment profile between metropolitan and nonmetropolitan places parallels that of population this paper introduces a data series compiled from county business patterns that is used to analyze the employment trends for the first time the analysis reveals that not only is total employment growing fastest in nonmetropolitan counties but it also appears that the turnaround in employment growth preceded the reversal in the rate of population increase manufacturing which had faster nonmetropolitan growth rates even during the 195os appears to have led in the development of nonmetropolitan counties this shift of manufacturing has attracted other sectors as well as people to nonmetropolitan places part of the recent growth of nonmetropolitan counties represented nothing more than a continuation of suburbanization or spillover of people and jobs which permitted one more outward bound into adjacent nonmetropolitan counties but there is more to nonmetropolitan development than simply metropolitan spillover nonmetropolitan counties far removed from metropolitan ones are also growing faster than metropolitan counties it is shown that this rural renaissance is part of a general deconcentration

upward bias in the consumer price index under the zero inflation economy abstract this study estimates the demand system using japanese microdata and calculates the cost of living index coli in the recent zero inflation situation the consumer price index cpi can approximate the coli while there are upward biases in the cpi during the 1980s

the nature of the savings function in developing countries a survey of the theoretical and empirical literature the savings rate marginal or average is regarded as a key performance indicator by development economists and foreign aid practitioners admonish their clients to increase their savings ratio as a primary condition for achieving a satisfactory rate of economic growth however not only have questions been raised regarding the significance of the savings effort as an independent determinant of economic progress but the formulation of policies designed to increase the savings propensity has suffered from a dearth of knowledge regarding the nature of the savings function in developing countries a number of alternative savings hypotheses derived mainly from the literature relating to developed economies have been advanced but the paucity of reliable data has made it difficult to test these hypotheses and obtain results which warrant a reasonable degree of confidence the purpose of this article is a to review the theoretical and empirical literature on the savings function in developing countries b to assess critically the findings with respect to the major hypotheses and c to summarize the state of our knowledge on this important topic we shall begin with a brief review of the nature of the data on savings in developing countries with which economic analysts must work

the interest elasticity of savings in developing countries the existing evidence abstract this paper presents a critical analysis of some of the most recent empirical work on the interest elasticity of savings in developing economies supported by a set of empirical results the paper argues that a the real interest elasticity of savings is not easily detected using the existing empirical models which generally yield insignificant interest rate parameters in the seventies b the existing models suffer from serious defects that make if very difficult to interpret the estimated parameters

financial liberalization in africa abstract recent evidence has shown that african economies are financially repressed and the underlying motives for perpetuating repressive policies still exist increasing real deposit rates mainly through lower inflation promotes financial savings investment and growth financial liberalization in africa has recorded limited success owing to a high and unstable inflation rate the high cost of financial intermediation low bank demand for deposits and persistent government interference in credit markets chronically high fiscal deficits and their adverse impacts on the balance of payments also constitute hurdles for financial deepening in africa

concrete agglomeration benefits do roads improve urban connections or just attract more people cities with more roads are more productive however it can be unclear whether roads increase productivity directly through improved intra urban connections or indirectly by attracting more people our theory suggests that population responses may obscure the direct connectivity effects of roads indeed conditional on population size highway density does not affect productivity in a sample of us metropolitan areas however when exploiting exogenous variation in urban populations we find that highway density improves agglomeration benefits moving from the 50th to the 75th percentile of highway density increases the productivity to population elasticity from 2 to 4 moreover travel based measures outperform population size as a measure of agglomeration externalities

financial development and economic growth international evidence the importance of the relationship between financial development and economic growth has been well recognized and emphasized in the field of economic development 1 although recent writings on this subject seem to accept the hypothesis that financial development is crucial for successful economic growth 2 patrick asked the critical question which sector financial or real leads in the dynamic process of economic development patrick identified two possible patterns in the causal relationship between financial development and economic growth in the first growth induces an expansion of the financial system 3 according to this view called demand following the lack of financial growth is a manifestation of the lack of demand for financial services as the real side of the economy develops its demands for various new financial services materialize and these are met rather passively from the financial side in the second pattern the expansion of the financial system precedes the demand for its services channeling scarce resources from small savers to large investors according to relative rates of return the financial sector precedes and induces real growth the deliberate establishment and promotion of financial institutions in many less developed countries ldcs might reflect this belief in the supply leading relationship between the two developments a natural question then concerns the direction of causality between financial development and economic growth patrick asserted that the direction of causality changes over the course of development in his view financial development is able to induce real innovation type investment before sustained modern economic growth gets under way and as the process of real growth occurs the supply leading impetus gradually becomes less important and the demand following financial response

second best cost benefit analysis in monopolistic competition models of urban agglomeration abstract this paper examines the agglomeration benefits of a transportation improvement in a city by modeling the microstructure of urban agglomeration based on monopolistic competition of differentiated intermediate products properly extended to include variety distortion in addition to price distortion harberger s measure of excess burden yields the agglomeration benefits the agglomeration benefits are positive if increasing the variety is procompetitive however in the anticompetitive case we cannot exclude the possibility of negative additional benefits if there are multiple cities the net agglomeration benefits can be negative when other cities that experience a reduction in population have larger agglomeration economies

non parametric tests of consumer behaviour the neoclassical model of consumer behaviour postulates that a consumer s choice behaviour can be described as deriving from utility maximization subject to a budget constraint one is then naturally led to ask what this model implies about observed behaviour this question has been addressed from two quite distinct approaches the first approach originating in the work of slutsky 1915 and antonelli 1886 derives necessary and sufficient conditions involving the derivatives of the demand functions the second approach originating in the work of samuelson 1938 1947 1948 derives algebraic conditions on the demand functions implied by maximizing behaviour

optimal policies in cities with congestion and agglomeration externalities congestion tolls labor subsidies and place based strategies abstract this paper develops a spatial general equilibrium model that accommodates both congestion and agglomeration externalities while firms and households land use decisions are endogenous across continuous space focusing on the interaction between externalities and land use patterns we examine the efficiencies of first best policies and second best pricing and place based strategies using numerical simulations a first best policy must combine both pigouvian congestion tolling pct and pigouvian labor subsidies pls instruments or design an optimal toll or subsidy internalizing agglomeration externalities or congestion externalities we also examine second best pricing policies if only one instrument is adopted congestion pricing policies alone e g a partial pct or a flat rate toll can improve social welfare only in heavy congestion cities and their welfare gains may be insignificant e g below 10 of the welfare improvement achieved by first best policies in contrast second best labor subsidy policies alone are a more effective alternative to first best policies as to place based policies the firm cluster zoning fcz regulation is more efficient than the urban growth boundary ugb policy ugbs only have small effects on the agglomeration economy but could worsen land market distortions via residential rent escalation effects these findings suggest that it is important to internalize business land use decisions and relax monocentricity assumptions in order to appreciate the interplay of both urban externalities since spatial adaptations to policy interventions can distort system efficiencies

interest rates savings and growth in ldcs an assessment of recent empirical research abstract the mckinnon shaw proposition of a positive interest responsiveness of savings and the beneficial effects of financial liberalization policies on economic growth has been an issue of considerable debate and a foundation of policy practice in less developed countries ldcs this paper aims at assessing critically a number of recent contributions to the empirical literature dealing with this proposition the need to advance more knowledge in this field on empirical grounds is argued despite the data conceptual and methodological shortcomings faced in making these efforts the main conclusion of this paper is that the debate is far from being settled even for those countries on which empirical research has focused

interest rate management in ldc s the mckinnon argument that higher time deposit rates raise output and lower inflation in the short run and increase medium term growth by raising the savings rate are shown to depend crucially on the assumption that portfolio shifts into td s come out of an asset providing less intermediation than the banking system we show that if instead the shift is out of an asset providing more intermediation e g loans on a curbmarket raising td rates is contractionary in the short run may have negative impacts on growth and can lead to more rather than less inflation in the short run

assessing the impact of interest rates in less developed countries abstract empirical results obtained do not unambiguously support what one should expect on the basis of conventional economic theory cross country evidence on the average relationship for 64 ldcs during the period 1971 1980 between some of the macroeconomic variables such as rate of growth of real gdp real financial assets saving income and investment income ratios and rate of return on investment on the one hand and the level of the real interest rate on the other is analyzed by applying a non parametric mann whitney test it is found that there is no difference with any statistical significance between the two groups of ldcs above and below the mean real interest rate this implies that the level of the real interest rate by itself has little or no impact on the selected macroeconomic variables

good bye financial repression hello financial crash some unintended consequences of financial liberalization in latin america are analyzed in this paper intrinsic imperfectious in financial markets and the policy dilemmas they pose are reviewed first the stylized facts of southern cone experiments in financial liberization are then presented alternative ways of organlzing domestic capital markets under latin american conditions are discussed and an eclectic reform mongering program is proposed

how revealing is revealed preference this lecture address the following two key criticisms of the empirical application of revealed preference theory when the rp conditions do not reject they do not provide precise predictions and when they do reject they do not help characterize the nature of irrationality or the degree direction of changing tastes recent developments in the application of rp theory are shown to have rendered these criticisms unfounded a powerful test of rationality is available that also provides a natural characterization of changing tastes tight bounds on demand responses and on the welfare costs of relative price and tax changes are also available and are shown to work well in practice

overview and summary this symposium analyzes the recent liberalization and stabilization attempts in chile argentina and uruguay attempts remarkable for their speed and coverage to bring these analyses together in one volume seems natural because the three experiences were so similar all three countries started with highly protected economies inflation balance of payments crises widespread government intervention and production systems in considerable disarray all three countries launched liberalization policies that spanned commodity and factor markets and all three followed the same path toward stabilization the battle against inflation was first based on control of the money supply then the exchange rate was used to reduce inflationary expectations the initial results were as remarkable as the reforms inflation was reduced fiscal deficits were controlled and growth was restored but in the early 1980s all three countries were again in crisis the objective of the reforms was to realize the gains from better allocations of resources and investment this objective was to be achieved by moving to market regulated economies one intention was to eliminate the traditional bias against exports and thus to spur the growth of exports which required an increase in the effective exchange rate for exportables and a decrease in that for import competing sectors a second intention was to deregulate interest rates and foreign capital inflows and thus to provide more credit to activities with the highest returns the motive here is to draw the lessons for other developing countries confronting liberalization and stabilization problems why did these unusual experiments fail to what extent did various parts of the packages succeed or fail was the failure due to external events or to bad policies were the institutional arrangements for deregulation appropriate the introduction to part i presents some analytical issues that arise from the experiences of the three countries it addresses the general issue of opening an economy to trade and to flows of foreign capital and the related issues of sequencing and policy coordination it also explores differences in the speed of adjustment in labor and commodity markets and the implications of these differences for the design of macroeconomic policy the other papers in part i explain and evaluate the macroeconomic performance of the liberalization and stabilization policies in each country first each paper describes the reforms and in an appendix provides a chronology of the many reforms perhaps the place to start for the uninitiated reader the descriptions are accompanied by summaries of the authorities intentions when the reforms were launched the approach to implementation is also addressed when it gave rise to policy reversals and conflicting signals second the papers construct stylized analytical frameworks to help interpret the macroeconomic outcome of the liberalization and stabilization policies in each country these frameworks help to draw the stylized outcomes of the reforms the papers in part ii rely on financial statements to analyze the adjustments by firms the data span the period covered by the reforms in each country and provide the basis for simple statistical models groups of firms exporters vs

transport infrastructure investment implications for growth and productivity theory and evidence on the effects of public investment on growth and productivity are reviewed it is concluded that on average public capital has positive impacts on output and private investment partly offset by the effects of the taxation needed to finance it a possible future shortfall in public capital in the uk is highlighted the paper also reviews the contribution of transport infrastructure to productivity and considers implications for cost benefit analysis it is suggested that there is a case for greater uk investment in roads but ideally this should be implemented along with an efficient national road pricing scheme

financial repression the new structuralists and stabilization policy in semi industrialized economies abstract this paper examines the short and long run effects of a variety of macroeconomic policies in a simple model where the curb market plays a pivotal role as the marginal supplier of loanable funds it is found that financial liberalization may fail in the short run and contrary to the claims of the new structuralists that the financial market repercussions of devaluation may be favorable in evaluating any policy the time horizon is critical short and long run multipliers may differ in sign in all cases save that of a contraction in the stock of bank credit

nonparametric engel curves and revealed preference this paper applies revealed preference theory to the nonparametric statistical analysis of consumer demand knowledge of expansion paths is shown to improve the power of nonparametric tests of revealed preference the tightest bounds on indifference surfaces and welfare measures are derived using an algorithm for which revealed preference conditions are shown to guarantee convergence nonparametric engel curves are used to estimate expansion paths and provide a stochastic structure within which to examine the consistency of household level data and revealed preference theory an application is made to a long time series of repeated cross sections from the family expenditure survey for britain the consistency of these data with revealed preference theory is examined for periods of consistency with revealed preference tight bounds are placed on true cost of living indices

money credit constraints and economic activity when government expenditures exceed current tax revenues the resulting deficit must be financed either by issuing bonds which imply obligations to levy future taxes or by creating high powered money the choice between money and bonds is often thought to be of great moment for both real and nominal variables that is monetary policy matters there is by now a wide empirical consensus that monetary policy has effects on real variables like output and employment but there is far less agreement about why this is so the purpose of this paper is to take issue with some currently fashionable views of why money has real effects and to suggest a new theory or rather resurrect an old one the loanable funds theory and give it new improved microfoundations this abstract was borrowed from another version of this item

traffic congestion accessibility to employment and housing prices a study of single family housing market in los angeles county this study mainly addresses two main questions 1 whether traffic congestion negatively affects single family house price by constraining accessibility to jobs 2 whether congestion effects and

estimating the true cost of living for households with different incomes using data from taiwan this empirical study investigates why the true costs of living for different income groups in taiwan as measured by the superlative tornqvist price index have grown dissimilarly over the sample period specifically it shows that using the aggregate cost of living col estimates for the entire households as is commonly practiced would produce noticeable group bias effect in measurement also the magnitude of the commodity substitution bias in the conventional consumer price index cpi is found to be positively related to household income in general because of the presence of these two biases the true col for households belonging to the two ends of the income spectrum is found to be over estimated this article is therefore in full agreement with arrow s proposition that an alternative and separate set of price index be constructed

should the cost of living index provide the conceptual framework for a consumer price index in some countries the cost of living col index serves as the conceptual framework for the cpi but it has been rejected in others this paper reviews issues that have arisen in the statistical agency debate and in the economics literature on the col index including rhetorical matters which have influenced the debate i contend that col theoiy is useful as a decision making framework in estimating components of the cpi and that col index theory provides appropriate guidance for measuring consumer inflation contrary to the view that has been adopted for the european hicp and expressed by an advisory committee for the rpi in several countries the united states netherlands sweden the theory of the cost of living col index provides the conceptual framework for the country s consumer price index cpi see united states department of labor 1997 balk 1994 and dalen 1999 others reject the cost of living index framework an example is the australian bureau of statistics 1997 rejection of the col index is also explicit in an rpi advisory committee recommendation in the united kingdom in still other countries canada being an example official documents for the cpi are ambiguous about the role of the col index statistics canada 1995 the international guideline for consumer price indexes the ilo manual turvey 1989 does not even mention the col index the question has taken on heightened interest recently part of the stimulus comes from the european union s relatively new harmonised indexes of consumer prices hicp for the hicps eurostat has rejected the col

models of financially repressed developing economies abstract the past decade has witnessed an explosion of research on financial sector models of financially repressed developing economies for the most part financial repression is interpreted to be the technique of holding interest rates particularly deposit rates of interest below their free market equilibrium levels the recent spate of activity in this field was produced by the simultaneous publication in 1973 of books by mckinnon and shaw both authors demonstrate how economic theory can be applied to the analysis of the effects of financial conditions on investment and the real rate of economic growth since 1973 models of financially repressed developing economies have been formalized mathematically extended to open economies in order to analyse exchange rate policies and tested empirically this paper presents a critical survey of the major contributions to the literature in this field since 1973

reforms and macroeconomic adjustments in chile during 1974 1984 abstract this paper provides a background on the main macroeconomic developments of the reform period after a review of the macroeconomic disequilibrium before the reforms the paper interprets the macroadjustments the interpretation covers two distinct periods 1973 1976 when policy was based on a closed economy view and 1977 1982 when macropolicy was increasingly guided by an open economy model the paper argues that the setback that chile suffered during 1982 1983 and the large external debt that was accumulated were the result of two major errors the first was the use of the exchange rate to stabilize prices without due regard for the incentives for large capital inflows that arose from this policy at a time when international capital markets were very liquid the second major error was in the second half of 1981 after a large drop in capital inflows the authorities relied on an automatic adjustment mechanism by which the monetary squeeze from the reduction in capital inflows would improve the real exchange rate because wages were indexed to prior inflation the adjustment mechanism was bound to create substantial unemployment as indeed was the case the paper concludes with the assessment that most of the micro reforms were in the right direction and had the expected result and the errors were mostly in the design of macroeconomic policies

explaining african economic performance africa has had slow growth and a massive exodus of capital in many respects it has been the most capital hostile region we review and interpret the aggregate level and microeconomic literatures to identify the key explanations for this performance there is a reasonable correspondence of the two sets of evidence pointing to four factors as being important these are a lack of openness to international trade a high risk environment a low level of social capital and poor infrastructure these problems are to a substantial extent attributable to government behaviour and the paper includes a review of the political economy literature which addresses that behaviour

measuring the substitution bias in japan the demand system approach and a superlative index this study estimates the demand system using japanese micro data and calculates the cost of living index coli to assess the substitution bias in the consumer price index the estimated bias during the sample period of 1982 2000 is about 0 06 percentage points which is larger than the estimates calculated from a superlative index the difference between the coli and a superlative index can be explained with the upward movements of the average utility level in japan since the cost of living for the rich has grown more rapidly than that for the poor

macro economic effects of changes in bank interest rates simulation results for south korea abstract we use an empirical macro econometric model of korea to simulate the impact of bank interest rate changes this model includes a very detailed sub model of the financial sector plus in addition to the usual demand side transmission channels of monetary policy a link between the financial sector and the supply side of the real part of the economy via the cost of financing working capital cavallo effect increases in time deposit rate are shown to be contractionary in the short run because the portfolio shifts they trigger tighten credit conditions and cause higher costs of financing working capital people shift out of the curbmarket rather than out of cash the higher cost of financing working capital also pushes up inflation in the first quarter after the change making the increase in td rates stagflationary this effect dies out quickly however the persistence of the loss in output is shown to depend on whether the commercial banks are allowed to play their intermediary role or not if credit limits prevent the passing through into bank loans of the influx of time deposits caused by the higher rates substantial and persistent real output losses and decreased private investment were shown to result

agglomeration economies in urban manufacturing industries a case of japanese cities abstract the effects of urban agglomeration economies on productivities in two digit manufacturing industries is estimated using the cross section data of japanese cities in 1979 urbanization and localization economies which are major forms of urban agglomeration economies are explicitly separated the estimates of these economies vary considerably among industries light industries receive more productive advantages from urbanization economies than from localization economies but heavy industries experience these economies more from localization economies than from urbanization economies

the substitution bias of the laspeyres price index an analysis using estimated cost of living indexes the most commonly used measure of the cost of living the consumer price index cpi published by the bureau of labor statistics is essentially a laspeyres price index it is well known however that a laspeyres price index provides an upward biased estimate of the cost of living because in keeping the same base period basket of goods as weights it does not take into account substitution among commodities induced by relative price changes the magnitude of the bias is an empirical question which is the focus of this study an estimate of the substitution bias may be obtained by taking the difference between the laspeyres price index and an estimated true cost of living index the true cost of living index cli is based on the theory of consumer demand it is the ratio of the minimum expenditures under two different price regimes necessary to maintain a constant level of utility as opposed to the constant basket of goods in the laspeyres index the size of the bias depends on two factors 1 the size of consumption substitution elasticities if there is no commodity substitution then the cli and laspeyres index coincide regardless of changes in relative prices and 2 the magnitude of relative price changes if all prices move together then the cli and laspeyres index again coincide regardless of the size of substitution elasticities in order to compute a true cli it is necessary to specify a particular utility function and estimate the parameters of the resulting system of demand equations see for example louis phlips p 135 several estimates of the magnitude of the substitution bias have appeared in the literature but all previous studies suffer from a common weakness they are all based on a very small number of commodities essentially because of econometric problems involved in estimating large systems of demand equations in one group of studies demand models have been estimated using highly aggregated data in which total consumption is grouped into four to nine aggregate commodites such as housing durables or clothing arthur goldberger and theodore gamaletsos for example estimate the linear expenditure system les demand model using data on five aggregate goods for several european countries and compare the resulting cli for one of the countries greece to the corresponding laspeyres price index tran van hoa estimates costof living indexes for six australian provinces using data on nine aggregate goods phlips cites work by r sanz ferrer who computed a cli for belgium from data on eight aggregate commodities in such studies using highly aggregated data the estimate of the substitution bias may be understated because the aggregation obscures substitution in consumption within categories which is perhaps more prevalent than substitution between gross aggregates another shortcoming of these three aggregate studies is the fact that they use only a single demand system and hence do not explore the sensitivity of the cli to a priori u s bureau of labor statistics the groundwork for this study was my dissertation i would like to thank the chairman and members of my committee r robert russell llad phillips and robert deacon for their support and helpful suggestions and jack triplett robert pollak richard j mcdonald and a referee for valuable comments on an earlier version the views expressed are my own and do not necessarily reflect the policies of the bureau of labor statistics for a theoretical discussion of cost of living indexes see robert pollak 1971b and paul samuelson and subramanian swamy

inefficiencies from financial liberalization in the absence of well functioning equity markets since the seminal works by mckinnon 1973 and shaw 1973 there has been active research into the working of financially repressed economies and the beneficial effects of elnancial liberalization see fry 1982 for a survey of literature they claim that liberalization of the elnancial sector from interest rate ceilings and other restrictions facilitates economic development and growth because higher interest rates lead to both increased savings and greater efficiency of capital allocation today the idea that financial activity should not be repressed has become the new orthodoxy in academia as well as in the major international institutions that provide policy guidelines for developing countries the elnancial liberalization argument however is incomplete the literature on emancial liberalization has emphasized eliminating interest rate ceilings and fostering free competition among banks it has largely overlooked the possibility that endogenous constraints in the credit market such as imperfect information could be signielcant barriers to efelcient credit allocation even when banks are freed from interest rate ceilings nor has the literature dealt with market structure e g the oligopolistic and cartelized banking systems found in most locs the literature has emphasized the role of the banking sector which is correctly perceived as the only organized capital market in most developing countries it has neglected the potential

saving in developing countries theory and review in the literature on economic development much of the interest in saving has been focused on the relation between saving and growth but saving is not only about accumulation it is about smoothing consumption in the face of volatile and unpredictable income and helping to ensure the living standards of poor people whose lives are difficult and uncertain this paper develops a model of households which cannot borrow but which accumulate assets as a buffer stock to protect consumption when incomes are low such households dissave as often as they save do not accumulate assets over the long term and have on average very small asset holdings but their consumption is markedly smoother than their income much of the evidence is as consistent with this view of saving as it is incosistent with standard views of smoothing over the life cycle and with explanations of the link between saving and growth in terms of life cycle saving behavior consumption smoothing is also a useful way of thinking about government policy where volatility in the world prices of taxed commodities can generate sharp fluctuations in government revenues as well as reallocations of revenue between the private and public sectors many important policy issues in developing countries hinge on issues of consumption and smoothing and research on these issues is currently likely to be more productive than work on the relation between saving and growth

the cost of living with the rpi substitution bias in the uk retail prices index this paper uses revealed preference restrictions and nonparametric statistical methods to bound the true cost of living index which corresponds most closely to the uk retail prices index rpi this is used to assess the rpi formula for substitution bias we show that neither the direction nor the existence of bias in the rpi forumla can be established on a priori theoretical grounds however we find empirical evidence of a variable but generally positive bias in the rate of inflation recorded by the rpi formula

the translog production function and variable returns to scale this paper examines existing methods of estimating the translog production function and provides a general framework that allows for variable returns to scale the model is based on the inverse input demand function and embeds a nonhomothetic production technology previous estimation methods are valid only for homogeneous technologies with fixed scale effects estimation results for u s manufacturing show that neither homotheticity and homogeneity nor constant returns to scale is a proper characterization of the underlying structure of production thereby vindicating the empirical relevance of the inverse demand framework that entails a nonhomothetic technology copyright 1992 by mit press

firm location and city size reduced productivity advantages as a factor in the decline of manufacturing in urban areas abstract this paper develops a model of firm location and city size that arrives at theoretical conclusions that differ from those of other authors comparative statics results suggest that changes in national wage levels and productivity levels create no determinate dis advantage for large cities relative to small ones as sites for manufacturing activity increased wage and reduced productivity premiums of large cities however result in unambiguous disadvantages statistical analysis indicates that the productivity advantages of large cities have declined in as many as eight two digit manufacturing industries that provide more than one third of metropolitan production worker employment

traffic congestion s economic impacts evidence from us metropolitan regions traffic congestion alleviation has long been a common core transport policy objective but it remains unclear under which conditions this universal byproduct of urban life also impedes the economy using panel data for 88 us metropolitan statistical areas this study estimates congestion s drag on employment growth 1993 to 2008 and productivity growth per worker 2001 to 2007 using instrumental variables results suggest that congestion slows job growth above thresholds of approximately 4 5 minutes of delay per one way auto commute and 11 000 average daily traffic adt per lane on average across the regional freeway network while higher adt per freeway lane appears to slow productivity growth there is no evidence of congestion induced travel delay impeding productivity growth results suggest that the strict policy focus on travel time savings may be misplaced and instead better outlooks for managing congestion s economic drag lie in prioritising the economically most important trips perhaps through road pricing or in providing alternative travel capacity to enable access despite congestion

what do we learn about consumer demand patterns from micro data the aim of this paper is to assess the importance of using micro level data in the econometric analysis of consumer demand to do this we utilize a time series of repeated cross sections covering some 4 000 households in each of 15 years employing a number of different aggregation procedures we conclude that aggregate data alone are unlikely to produce reliable estimates of structural price and income coefficients however once certain aggregation factors as well as trend and seasonal components are included an aggregate model is not necessarily outperformed across all demand equations in terms of forecasting ability jel d12 c52 c31 the purpose of this paper is to develop a complete consumer demand system based on a time series of individual household data and to use it to measure the biases introduced into the study of consumer de mand behavior when aggregate data are used in place of the appropriate microeco nomic data we assess the suitability of ag gregate data through the impact on income and price elasticities and by evaluating the ability of both micro and aggregate based models to forecast aggregate consumer de mand the biases introduced by the use of aggregate data depend upon the way that household characteristics interact with in come and price effects and on departures of demand systems from linearity we explore the structure of microeconomic demand sys tems and the role of household characteris tics in the behavior of consumer demand both for the light this may shed on the pattern of future demands and for the im plications this behavior has for issues of aggregation consumer demand patterns typically found in micro data sets vary considerably across households with different household characteristics and with different levels of income we model this variability by making intercept and slope parameters in the budget share equations of our demand sys tem depend on household characteristics and by allowing for nonlinear total log expenditure terms in fact in theory consistent demand systems it is total ex penditure rather than disposable income that is allocated across goods we find that this general framework leads to a well specified data coherent demand system which is a quadratic extension of the popu lar almost ideal model of angus s deaton and john muellbauer 1980 the micro level estimates are shown to be sensitive to the treatment of endogeneity of total expen diture and to the specification of interaction terms with household characteristics in ad dition this specification is also shown to possess many attractive features for the evaluation of aggregate models
