policy watch infrastructure investment and economic growth in the late 1980s david aschauer 1989 triggered a long overdue dialogue among economists and political leaders when he published a study arguing that much of the decline in u s productivity that occurred in the 1970s was precipitated by declining rates of public capital investment my own work confirmed these results munnell 1990a spending advocates seized on these findings as support for increased public investment the enthusiasm among policymakers for the early aschauer results was matched if not surpassed by skepticism on the part of many economists critics of these studies charged that the methodology was flawed that the direction of causation between public investment and output growth is unclear and that even if the historical empirical relationships were estimated correctly they provide no clear indications for current policy who s right what do we know and not know about the link between public infrastructure and productivity and what are the implications of these results for policy

railways and the local economy evidence from qingzang railway abstractthis article empirically examines the causal effect of railway infrastructure on local economic development using the construction of qingzang railway as a natural experiment we apply the difference in difference method and find that the qingzang railway significantly stimulated the economy of the counties along its path railway counties the local gdp per capita increased by about 33 after the railway had begun to operate the effect manifested primarily through the positive railway effect on the manufacturing industry in addition the effect did not vary significantly with the initial economic status of the railway counties the gdp per capita of the off railway counties that are adjacent to the railway counties was not significantly affected

marketing orders grading errors and price discrimination some marketing orders allow an agricultural industry to regulate the flow of product to market we examine a more common but less controversial aspect of marketing orders the setting and enforcement of grades and show that purposefully introducing error into the grading process reduces farmers incentives to produce high quality product thus partially sustaining the adverse selection problem that would exist in the absence of grades because demand for high quality product is generally inelastic relative to demand for low quality product grading error can increase industry profit in principle an industry can achieve through grading error the same allocation of product between high and low quality outlets as attainable through direct volume regulation copyright 2002 oxford university press

infrastructure and development a critical appraisal of the macro level literature this survey reviews the existing macro level empirical literature on the link between infrastructure and development outcomes in a critical light after providing a general framework that casts the relevant terms of the controversy on the real effect of infrastructure on growth in the context of an aggregate production function it signals what are the relevant empirical questions to be addressed this guides the systematic review of a number of empirical studies and the discussion of the main econometric challenges to the identification of the effect of infrastructure on output and productivity finally building on related research in particular in contract theory and political economy the paper spells out several promising research avenues

institutions infrastructure and economic growth abstract this paper develops a structural model of infrastructure and output growth that takes account of institutional and economic factors that mediate in the infrastructure gdp interactions cross country estimates of the model indicate that the contribution of infrastructure services to gdp is substantial and in general exceeds the cost of provision of those services the results also shed light on the factors that shape a country s response to its infrastructure needs and offer policy implications for facilitating the removal of infrastructure inadequacies

security analyst superiority relative to univariate time series models in forecasting quarterly earnings abstract this paper provides evidence of security analyst sa superiority relative to univariate time series ts models in predicting firms quarterly earnings numbers and shows that sa forecast superiority in our sample is attributable to 1 better utilization of information existing on the date that ts model forecasts can be initiated a contemporaneous advantage and 2 use of information acquired between the date of initiation of ts model forecasts and the date when sa forecasts are published a timing advantage

an evaluation of univariate time series earnings models and their generalization to a single input transfer function the development of statistical models for accounting earnings has been an evolving process earlier studies used simple index and or naive models e g ball and brown 1968 and brown and kennelly 1972 because of the lack of tools to deal with formal time series later dopuch and watts 1972 ball and watts 1972 and others employed formal time series models to annual earnings and collins and hopwood 1980 brown and rozeff 1979 foster 1977 griffin 1977 and watts 1975 did the same with quarterly earnings while this research has produced some conclusions with respect to the time series properties of earnings and how these may be used in predicting earnings brown and rozeff 1978 and then collins and hopwood 1980 recently provided evidence that financial analysts can produce forecasts more accurate than those based on the arima models alone this suggests that other information may be useful in providing estimates of future earnings when incorporated with knowledge of the time series properties of earnings the purpose of this study is twofold a we first evaluate the models used in past studies of quarterly time series of earnings in order to determine whether they are systematically misspecified due to the omission of other information which is implicitly contained in a market earnings index the evidence suggests that the misspecification exists and b we introduce a transfer function model which utilizes the timeseries properties of both the index and earnings numbers this model is obtained based on both theoretical derivation and inspection of data

linking local business with global growth opportunities the role of infrastructure infrastructure is instrumental when it comes to linking local businesses with their global growth opportunities this paper shows that by making this link the transport network can act as a catalyst for regional economic growth using a novel approach we find that firms in regions with a more developed transport infrastructure are better placed to benefit from positive growth opportunities than those in regions with a less well developed transport network this advantage is most pronounced in times of economic slack making a better transport network a key ingredient for economic recovery it is against this background that the recent slowdown in infrastructure investment in europe is worrisome but it is through this channel among others that the substantial ramp up of activity by the european investment bank is expected to foster growth and enhance competitiveness in europe

stochastic properties of cross sectional financial data financial data may be viewed as random variables which imperfectly reveal information about a firm s financial and operating activities inferences based on such information from cross sectional financial data will be dependent upon the characteristics of the underlying stochastic processes generating these data and whether these can be identified deakin 1976 conducted a comprehensive study of the stochastic properties of financial ratios after examining the cross sectional distribution of 11 ratios over the 1953 72 period for large populations of manufacturing firms he concluded that the typical normality hypothesis had to be rejected except perhaps for the debt asset ratio one possible reason for the absence of normality in financial data is a failure to achieve appropriate factorial control cross sectional financial data can be affected by many systematic factors for example a firm s current assets generally depend on its size its industry s credit practice the nature of its output market its current

the politics of infrastructure a number of recent studies attempt to measure the productivity of public capital some estimates indicate that government investments are a potential well spring for economic progress while others indicate that public infrastructure has a negligible effect on private sector output this article investigates political institutions and processes underlying the decisions for public infrastructure spending we apply the framework of strategic models of fiscal policy and develop an empirical model to analyze the substantial differences in public capital across american states institutions such as term limits citizen initiative and budgeting procedures were significant determinants of state public capital stocks and the flow of new public investments during the 1980s the results further suggest that political conditions such as legislative stability and voter volatility are systematically related to infrastructure differences across states

on the deadweight cost of production requirements for geographically differentiated agricultural products this article investigates the welfare effects of alternate producer collusion schemes in a context where collusion is authorized in order to cover fixed costs using a linear equilibrium displacement model we find evidence that when the producer group is allowed to control quota levels an input quota policy entails a smaller absolute deadweight loss than an output quota policy this finding suggests that if producer groups are allowed to resort to production distorting instruments to limit output they will make production choices that are less costly for society than if they had been allowed to directly control output levels copyright 2008 oxford university press

the contribution of local public infrastructure to private productivity and its political economy evidence from a panel of large german cities this paper proposes a simultaneous equation approach to theestimation of the contribution of infrastructure accumulationto private production a political economy model for theallocation of public infrastructure investment grants isformulated our empirical findings using a panel of largegerman cities for the years 1980 1986 and 1988 suggest thatcities ruled by a council sharing the state bundesland government s current political affiliation were particularlysuccessful in attracting infrastructure investment grants with regard to the contribution of infrastructure accumulationto growth we find that public capital is a significant factorin private production moreover at least for the samplestudied we find that simultaneity between output and publiccapital is weak thus feedback effects from output toinfrastructure are negligible

aid and the supply side public investment export performance and dutch disease in low income countries contemporary policy debates on the macroeconomics of aid often concentrate on short run dutch disease effects ignoring the possible supply side impact of aid financed public expenditure in the simple model of aid and public expenditure presented here public infrastructure generates an inter temporal productivity spillover which may exhibit a sector specific bias the model also provides for a learning by doing externality through which total factor productivity in the tradable sector is an increasing function of past export volumes an extended computable version of this model is used to simulate the effect of a step increase in net aid flows the simulations show that beyond the short run when conventional demand side dutch disease effects are present the relationship between enhanced aid flows and real exchange rates output growth and welfare is less straightforward than simple models of aid suggest public infrastructure investment that generates a productivity bias in favor of non tradable production delivers the largest aggregate return to aid but at the cost of deterioration in the income distribution income gains accrue predominantly to skilled and unskilled urban households leaving the rural poor relatively worse off under plausible parameterizations of the model the rural poor may also be worse off in absolute terms

is infrastructure capital productive a dynamic heterogeneous approach this paper offers an empirical evaluation of the output contribution of infrastructure drawing from a large data set on infrastructure stocks covering 88 countries and spanning the years 1960 2000 and using a panel time series approach the paper estimates a long run aggregate production function relating gdp to human capital physical capital and a synthetic measure of infrastructure given by the first principal component of infrastructure endowments in transport power and telecommunications tests of the cointegration rank allowing it to vary across countries reveal a common rank with a single cointegrating vector which is taken to represent the long run production function estimation of its parameters is performed using the pooled mean group estimator which allows for unrestricted short run parameter heterogeneity across countries while imposing the testable restriction of long run parameter homogeneity the long run elasticity of output with respect to the synthetic infrastructure index ranges between 0 07 and 0 10 the estimates are highly significant both statistically and economically and robust to alternative dynamic specifications and infrastructure measures there is little evidence of long run parameter heterogeneity across countries whether heterogeneity is unconditional or conditional on their level of development population size or infrastructure endowments

strategic trade policy with endogenous choice of quality and asymmetric costs abstract this paper examines strategic trade and joint welfare maximizing incentives towards investment in the quality of exports by an ldc and a developed country firms first compete in qualities and then export to an imperfectly competitive third country market under bertrand competition unilateral policy involves an investment subsidy by the low quality ldc and an investment tax by the developed country whereas jointly optimal policy calls for the reverse so as to reduce price competition by increasing product differentiation under cournot competition unilateral policy is also reversed from the bertrand outcome but jointly optimal policy involves a tax in both countries

recursos naturales diversificacion y crecimiento regional en el peru based upon the export product space this paper shows the main features of the export product composition of peru and its regions with respect to export baskets these include a high con centration in few commodities a relatively low degree of similarity between products relatively high levels of productivity at the international level and enormous undiscovered or untapped export potential in addition this paper analyzes the hypothesis that the natural resource curse affects regional growth employment and export diversification subject to the limitations of the data and the heterogeneous panel methods employed estimation results indicate that the share of natural capital out of the total tangible wealth and natural capital per capita seems on average and in a relatively statistically robust way to spur growth primary employment and export concentration in a few products consequently the natural resource curse for the peruvian regions is not about growth but about low regional development since such resources do not have a significant impact on secondary and tertiary employment or on export product diversification

minimum quality standards as a barrier to innovation abstract most models of minimum quality standards do not deal with the dynamic nature of regulation this note shows that presence of minimum quality standards may reduce firm incentives to innovate leading to a lower level of social welfare under regulation

pleasures of cockaigne quality gaps market structure and the amount of grading the article explores under what circumstances high quality producers would not voluntarily submit to grading when low quality firms would readily do so and under what conditions high quality firms would have a lesser proportion of their output graded than would their low quality counterparts it also investigates how market structure affects the decison to grade establishing that a competitive industry carries out the optimal amount of grading when some firms have finite market shares the industry engages in excessive grading

empirical studies on the relationship between public and private investment and gdp growth this study performs empirical studies on the interaction between public and private investment and gdp growth for japan and the usa since the data for each country used show features that are quite different from each other empirical methods of gmm generalized method of moments and ols ordinary least squares are accordingly applied to japan and the usa respectively the empirical results suggest that both public and private investment make great contributions to japanese economic growth while the us private investment seems to play a much more significant role than public investment

minimum quality standards and collusion we model the introduction of a minimum quality standard in a vertically differentiated duopoly we extend the literature in determining the standard endogenously showing that the maximisation of social welfare entails an increase in the surplus accruing to consumers served by the low quality firm and a decrease in the surplus of the remaining consumers then we consider the effects of the standard on the stability of price collusion proving that the standard makes it more difficult for firms to collude if consumers are sufficiently rich

a comparative analysis of funding schemes for public infrastructure spending in quebec the economic literature has been investigating the positive relation between public infrastructure spending and the productivity of the private sector since munnell 1992 we have introduced this relationship into a recursive dynamic computable general equilibrium model of the quebec economy to investigate various funding schemes to scale up infrastructure spending in the province we draw our assumptions from estache et al 2010 combined with sectoral elasticity parameters we conduct a comparative analysis where the funding comes from debt alone and debt with sales tax income tax and business tax our main finding is that the income tax seems to produce the most positive effects and the businesses tax the most negative effects though differences are small

structural changes and the forecasting of quarterly accounting earnings in the utility industry abstract this paper presents a statistical procedure to identify effects of three potential structural changes on accounting earnings temporary short run and long run the procedure is applied to quarterly accounting earnings of 39 utility companies structural changes are found to be commonplace statistical forecasting models that explicitly incorporate structural change effects are found to generate more accurate forecasts than other statistical models in the literature although no statistical model significantly dominates value line a firm specific model with structural change adjustment forecasts as well as value line moreover all statistical models examined have significant marginal forecasting power to complement value line forecasts

the gains from price stabilization a quantitative assessment a widely discussed problem in economics is the benefits from price instability the original work by waugh used consumer surplus to show that individuals benefit from price variation vis a vis stabilization at the mean a later model by oi did the same for producers while massel integrated the two analyses an excellent account of the development of this problem is turnovsky 1978 these analyses relied on models of consumer surplus with linear or log linear demand functions neither of which can be derived from utility maximizing behavior as a result these demand curves do not relate to known measures of consumer welfare such as hicksian compensated variation or the true cost of living realizing this hanock recast the problem in terms of the indirect utility function under the assumption of cardinal utility hanock and turnovsky shalit and schmitz derived the conditions including those relating to risk under which consumers gain under the assumption of ordinal utility we prove the proposition that consumers gain from price instability next these benefits are quantified via a monte carlo experiment

crowding out the role of state companies and the dynamics of industrial competitiveness in india this article examines growth patterns of government companies in india whether their presence has crowded out private entrepreneurial activity and whether there has been a decline in the competitiveness of india s industry measured as relative productive efficiency for a 45 year period from 1957 1958 to 2001 2002 there was a significant growth in the number of government companies in india that effectively crowded out the entry and growth of private enterprise this took place from the mid to late 1950s to the late 1980s and early 1990s correspondingly the amount of private equity capital invested in firms declined until the late 1980s and early 1990s when there was an upsurge of private investment activity another feature was that a small number of government companies absorbed most of the corporate sector equity investment in india the growth in the share of government companies in india that crowded out the entry and growth of private enterprises has had a significantly negative effect on india s industrial competitiveness after the introduction of reforms in 1991 there has been a significant crowding in by private enterprises displacing the government companies from their key position as holders of a very large portion of equity capital and also reversing the trend in the decline of competitiveness of indian industry as a whole copyright 2009 oxford university press

public investment and regional inequality in rural china this paper develops a method for decomposing the contributions of various types of public investment to regional inequality and applies the method to rural china public investments are found to have contributed to production growth in both the agricultural and rural non agricultural sectors but their contributions to regional inequality have differed by type of investment and the region in which they are made all types of investment in the least developed western region reduce regional inequality whereas additional investments in the coastal and central regions worsen regional inequality investments in rural education and agricultural r d in the western region have the largest and most favorable impacts on reducing regional inequality

information asymmetry as a reason for food industry vertical integration three trends that have been subject to recent discussion are a movement away from undifferentiated agricultural commodities toward more specialized products reduced reliance on open markets for raw agricultural products and a movement toward agricultural industrialization recent research suggests that demographic trends may be causing the first trend while the other two are closely related phenomena this research suggests that information externalities arising from uncertainty concerning the nature of food quality and problems in detecting quality may be reasons why vertical coordination is being used to circumvent the marketplace

telecommunications infrastructure and economic development a simultaneous approach in diesem beitrag wird untersucht welchen einflus die telekommunikations infrastruktur auf die wirtschaftliche entwicklung ausubt diese wichtige frage hat im zusammenhang mit der diskussion um informationsautobahnen aktualitat erlangt in der vorliegenden studie wird der einflus der telekommunikations infrastruktur fur 21 oecdlander fur die vergangenen 20 jahre analysiert es wird ein strukturgleichungsmodell geschatzt in dem investitionen in die telekommunikations infrastruktur als endogene variable erfast werden und in einem mikromodell angebot und nachfrage nach telekommunikations investitionen spezifiziert werden das mikromodell wird dann zusammen mit der makro wachstumsgleichung geschatzt als ergebnis stellen die autoren dann eine positive kausalbeziehung zwischen telekommunikations investitionen und wirtschaftlicher entwicklung fest wenn eine kritische masse an telekommunikations infrastruktur existiert

optimal co investment in supply chain infrastructure abstract this paper considers co investment in a supply chain infrastructure using an inter temporal model we assume that firms capital is essentially the supply chain s infrastructure as a result firms policies consist in selecting an optimal level of employment as well as the level of co investment in the supply chain infrastructure several applications and examples are presented and open loop as well as feedback solutions are found for non cooperating firms long and short run investment cooperation and non simultaneous moves stackelberg firms in particular we show that a solution based on nash and stackelberg differential games provides the same level of capital investment thus selecting the leader and the follower in a co investment program does not matter we show that in general co investments by firms vary both over time and across firms and thereby render difficult the implementation of co investment programs for future capital development to overcome this problem we derive conditions for firms investment share to remain unchanged over time and thus be easily planned

efficient redistribution through commodity markets efficiency in redistribution is measured in terms of deadweight loss generated per dollar of economic surplus transferred between consumers and producers of a commodity by means of market intervention the implications of supply and demand elasticities for efficiency in redistribution are examined with special attention to the comparison of production control and deficiency payment programs the results may be used to aid in the evaluation of commodity programs and as a basis for consideration of the hypothesis that observed policies are efficient given the political power of interest groups

marshall s scale economies and jacobs externality in korea the role of age size and the legal form of organisation of establishments this paper revisits the concept of agglomeration economies by estimating the effects of localisation urbanisation and local competition on labour productivity using establish ment level data in korean manufacturing industries it is found that when an establish ment locates in a more localised specialised more urbanised diversified and more competitive area its workers become more productive due to external benefits from agglomeration issues of self selection bias and omitted variable bias are addressed by instrumenting the variables measuring localisation economies and controlling for the fixed effects of establishments location and industries year however the external effects from the spatial proximity of other establishments vary across the categories of industry type age size and legal form of organisation of establishments establishments in traditional heavy manufacturing industries receive more external benefits in a less diversified area while those in transport equipment manufacturing industries enjoy the largest benefits from localisation externalities exist for establishments aged between 2 and 7 years having at least 10 workers being corporate and having multiplants or not being headquarters establishments in relatively young industries rely more on diver sified environments while establishments in relatively old industries receive greater external benefits in the same industry cluster this result supports the product life cycle location theory of duranton and puga

is public expenditure productive abstract this paper considers the relationship between aggregate productivity and stock and flow government spending variables the empirical results indicate that i the nonmilitary public capital stock is dramatically more important in determining productivity than is either the flow of nonmilitary or military spending ii military capital bears little relation to productivity and iii a core infrastructure of streets highways airports mass transit sewers water systems etc has most explanatory power for productivity the paper also suggests an important role for the net public capital stock in the productivity slowdown of the last fifteen years

political parties and the supply side of the economy the provision of physical and human capital in advanced economies 1960 90 theory partisan tenure of government in contrast to institutionalist and structural approaches is used to explain the nature of governmental strategies to affect the supply side of the economy the provision of the input factors capital and labor hypotheses supply side economic strategies are a function of the party in office left wing governments spend heavily in physical and human capital formation to raise the productivity of factors and the competitiveness of the economy rightwing governments rely instead on private agents to maximize economic growth the organization of the domestic political economy and the international economy which place heavy limits on the capacity of parties to affect the conduct of macroeconomic policies hardly constrain the choice of supply side economic strategies methods regression analysis of data for levels of public spending on gross fixed capital formation and on education in oecd nations from 1960 to 1990 results supply side policies conform to partisan preferences throughout the period examined the institutional configuration of the economy affected policies jointly with government partisanship until the oil shock but not afterwards economic openness does not constrain the choice of supply side policies

on the optimality of public capital for long run economic growth evidence from panel data the role of public capital in economic growth is examined using data from the penn world tables and other sources on a large number of countries drawing on intertemporal optimization the theoretical framework nests the exogenous solow and endogenous types of growth and is data consistent it is found that public capital makes a significant contribution to growth the actual level of investment on public capital is suboptimal growth in recent decades can be characterized as endogenous with little sign of convergence there is evidence of a growth slow down between the 1970s and 1980s human capital also significantly enhances growth

productive efficiency and growth policies for the caribbean productive economic efficiency and factors affecting it was evaluated in the caribbean between 1983 to 1992 results from non parametric programming indicated that efficiency i e pure technical allocative and economic measures were lower and more variable in caribbean than in other western hemisphere countries i e north america and latin america tobit regression analysis indicated higher levels of private and foreign investments productive infrastructure credit availability education level and consumption of domestically produced goods had positive impacts on the efficiency measures on the other hand higher levels of public expenditure income tax and export taxes and higher inflation rates had negative effects these results support the current trend towards advocating more open economies i e letting the free market work and encouraging governments to confine their functions to facilitative regulatory type roles and to undertaking tasks that are not generally undertaken by the privat

efficiency adjusted public capital and growth summary this paper constructs an efficiency adjusted public capital stock series and re examines the public capital and growth relationship the paper also examines the effects of four specific stages of the public investment process appraisal selection implementation and evaluation on capital accumulation and growth the results show that public capital is a significant contributor to economic growth the quality of public investment as measured by variables capturing the adequacy of project selection and implementation is statistically significant in explaining variations in economic growth a result mainly driven by low income countries

airline traffic and urban economic development this paper provides new evidence on the link between airline traffic and employment in us metropolitan areas the evidence confirms the common view that good airline service is an important factor in urban economic development frequent service to a variety of destinations reflected in a high level of passenger enplanements facilitates easy face to face contact with businesses in other cities attracting new firms to the metro area and stimulating employment at established enterprises the empirical results show that a 10 per cent increase in passenger enplanements in a metro area leads approximately to a 1 per cent increase in employment in service related industries however airline traffic has no effect on manufacturing and other goods related employment suggesting that air travel is less important for such firms than for service related businesses these estimates are generated controlling for reverse causality between employment and traffic the results imply that expansion of chicago s o hare ai

services sector and economic growth in india this study examines the long run equilibrium and short run dynamic relationship between services sector and gross domestic product gdp and between services and nonservices sectors in india the model is estimated using the optimal single equation and the maximum likelihood system estimators all the estimators consistently suggest the cointegrating relationship between services sector and gdp as well as between services and nonservices sectors the estimates of long run elasticity parameters are statistically significant and dimensionally consistent across the estimators the conventional cumulative sum cusum and the new cusum and moving sum mosum tests suggest the stability of the equilibrium residuals and reinforce the cointegrating relationship between the model series the error correction model provides some support for unidirectional granger causality from services sector to gdp the impulse response and variance decomposition analyses instead suggest the bidirectional causality between servic

spillover effects of public capital formation evidence from the spanish regions maybe because of the inconclusive nature of the results on the impact of public capital on output at the regional level the issue of the po ssible existence of the regional spillovers from public capital formation has received little attention the objective of this paper is to provide evidence on the possible existence of such spillovers we consider the case of spain and its seventeen regions our methodological approach consists in estimating an aggregate var model for spain as well as seventeen region specific var models in which both capital installed in the region and capital installed outside the region are allowed to play a role in en hancing regional output the estimation results can be summarized as follows the aggregate effects of public capital formation in spain are important they cannot however be captured in their entirety by the direct effects in each region from public capital installed in the region itself when for each region both the capital installed in the region and the capital installed outside the region are considered the total disaggregated effect from the seventeen regional models are very much in line with the aggregate results furthermore the aggregate effect seems to be due in almost equal parts to the direct and spillover effects of public capital formation ultimately this paper establishes the relevance of both capital installed in each region and s pillover effects in the understanding of the regional decomposition of the aggregate effects of public capital formation in doing so it opens the door to some tantalizing and potentially highly charged research issues in terms of the determination of the optimal location of public investment projects

collective marketing arrangements for geographically differentiated agricultural products welfare impacts and policy implications this paper examines the incentive of atomistic agricultural producers within a specific geographical region to differentiate and collectively market products we develop a model that allows us to analyze the market and welfare effects of the main types of real world producer organizations using it to derive economic insights regarding the circumstances under which these organizations will evolve and describing implications of the results obtained in the context of an ongoing debate between the european union and united states as the anticipated fixed costs of development and marketing increase and the anticipated size of the market falls it becomes essential to increase the ability of the producer organization to control supply in order to ensure the coverage of fixed costs whenever a collective organization allows a market with a new product to exist that otherwise would not have existed there is an increase in societal welfare counterintuitively stronger property right protection for producer organizations may be welfare enhancing even after a differentiated product has been developed the reason for this somewhat paradoxical result is that legislation aimed at curtailing the market power of producer organizations may induce large technological distortions

the welfare implications of minimum quality standards previous analysis of the social welfare implications of minimum quality standards has yielded no decisive results in this paper the specific nature of consumer and producer responses to quality standards is incorporated into the analysis both consumer and producer gains are shown to be impossible when consumers can perceive quality before purchase even if low quality produce is diverted to secondary markets standards unambiguously reduce net social benefits the paper explores the possibility that minimum quality standards are a form of rent seeking behavior

marketing orders as nontariff trade barriers previous analysis shows that under autarky all groups must lose from minimum quality standards with symmetric information we find that with international trade it is possible for one country to gain by introducing minimum quality standards however it is not possible for both countries to gain from the standards this result implies that minimum quality standards are nontariff trade barriers using the walter and baldwin criteria

what have we learned from three decades of research on the productivity of public capital the last three decades have witnessed a great deal of research effort devoted to measuring the private output elasticity of public capital the wide range of available estimates have precluded any consensus so far however this paper reconciles the empirical findings of the literature by quantitatively analyzing a sample of 578 estimates collected from 68 studies for the 1983 2008 period using meta regression analysis we show how study design characteristics and publication bias can explain a large fraction of the variation across estimates we find a short run output elasticity of public capital supplied at the central government level of 0 083 which increases to 0 122 in the long run if in addition only core infrastructure at a regional local level of government is considered these estimates are almost doubled the average output elasticity of public capital amounts to 0 106 our results suggest that public capital is undersupplied in oecd economies

impacts of minimum quality standards imposed through marketing orders or related producer organizations we analyze the impacts of minimum quality standards mqs imposed by producers acting collectively through a producer organization such as a marketing order mqs imposed in a competitive market can never enhance social welfare because in general an mqs creates two deadweight losses one due to inefficient enhancement of product quality and a second due to wastage of the low quality product any mqs that a competitive industry implements based upon a profit criterion causes all consumers in the market to be harmed however an mqs may be preferred relative to supply control as a second best instrument for transferring income to producers
