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

are airports engines of economic development a dynamic panel data approach this paper applies the dynamic panel data generalized method of moments estimator to the data on commercial passenger air traffic at all primary airports in the united states to evaluate the impact of traffic volume and number of destinations served with non stop flights on the key indicators of regional economic development we find that number of destinations served with non stop flights has a much clearer and more robust impact on level of employment number of business establishments and average wage in the region passenger traffic volume affects employment and average wage but not number of establishments at the sample median connecting a metropolitan statistical area with an extra destination keeping everything else constant creates 98 jobs and facilitates the opening of four new business establishments that employ people the corresponding numbers for the sample mean are 223 jobs and 15 businesses the impact of air travel on regional economic development is influenced by competition on the

preventing competition because of solidarity rhetoric and reality of airport investments in spain from a public interest perspective there could be a justification for constraining market mechanisms with the aim of progressive redistribution however some policies might be based on selfish motivations of government agents in this article we empirically contrast if the infrastructure policy is based only on public interest motivations or if it is also based on the private motivations of policy makers in this way spain infrastructure policy provides a useful policymaking field to test hypothesis about the behaviour of policy makers we find some evidence regarding the strength of political motivations in explaining such behaviour in fact results from our analysis show that political motivations can eventually play a more relevant role than social welfare maximization

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

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

infrastructure investment a review essay economists try not to be faddists but they often cannot help themselves while work on a topic should mirror the prospective importance of the topic that situation seems to occur with disappointing frequency instead the usual pattern is that some reasonably important topic will be totally ignored for the longest time then recognized and then the subject of a flurry of work all out of proportion to its likely long run importance nowhere has this speculative bubble of economic research been more clearly illustrated than with infrastructure investment macroeconomists havelong felt that the stock of public capital is an important factor input in the production of total output macroeconomists have known that u s productivity growth slowed dramatically in about 1973 and macroeconomists should have known that united states investment in public capital has been down since the late 1960s yet analysis of the u s productivity slowdown completely ignored infrastructure investment for the first fifteen years of this slowdown concentrating instead on energy prices social regulation the composition of the work force research and development different rates of obsolescence of the private capital stock and any number of other matters the public capital stock was hardly ever even mentioned as a potential factor in the productivity slowdown aschauer changed all that he wrote a series of papers 1989a 1989b 1989c that put these two movements together econometrically infrastructure investment turned down and aggregate productivity turned down slightly later both in the united states and in some other developed countries his work hit the magic button those who had worried about the productivity puzzle for fifteen years welcomed a new suspect those who were worried about low rates of u s national saving welcomed a new way to make their argument even more forcefully than with official figures on saving and investment which do not count infrastructure investment as investment political liberals and liberal politicians saw a way to rescue government spending and projects from the assaults of reaganism and even a way to avoid oth

airport expansions and property values the case of chicago o hare airport abstract the paper adds to the empirical literature by providing up to date estimates of the effect of airport noise on property values around one of the world s busiest airports chicago o hare the results indicate that home values were about 9 lower within a 65 db noise contour band of o hare in 1997 opponents of airport expansions argue that increased noise will reduce property values and lower tax bases the results of this paper suggest that aircraft are becoming so much quieter that the airport can be expanded without causing a drop in local property values or tax bases estimates suggest that house prices may rise by as much as 284 6 million in the densely populated area around o hare after a new runway is added to the airport

too close for comfort geographic propinquity to political power and stock returns abstract we show that firm headquarters geographic proximity to political power centers state capitals is associated with higher abnormal returns consistent with the notion that this effect is rooted in social network links we find it is more pronounced in communities with high levels of sociability and political values homophily and that it dissipates when firms move their headquarters to another state finally in line with the view that investors perceive such networks to be associated with political risk we find that this effect is particularly strong when there are substantial levels of corruption dependency on government spending and politicians turnover

long range growth economic development in the global network of air links we study the impact of international long distance flights on the global spatial allocation of economic activity to identify causal effects we exploit variation due to regulatory and technological constraints which give rise to a discontinuity in connectedness between cities at a distance of 6000 miles we show that these air links have a positive effect on local economic activity as captured by satellite measured night lights to shed light on how air links shape economic outcomes we first present evidence of positive externalities in the global network of air links connections induce further connections we then find that air links increase business links showing that the movement of people fosters the movement of capital in particular this is driven mostly by capital flowing from high income to middle income but not low income countries taken together our results suggest that increasing interconnectedness generates economic activity at the local level by inducing links between businesses but also gives rise to increased spatial inequality locally and potentially globally

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

the effect of government corruption on the efficiency of us commercial airports abstract in this paper we argue that the cost of providing public goods is affected by local government corruption because bureaucrats have no strong incentives to pursue mandated tasks under a corrupt environment commercial airports in the united states are chosen to demonstrate such impacts of corruption we first develop a theory which predicts the impacts of corruption on productivity and variable input allocation of airports we then test the predictions by estimating a stochastic variable cost frontier model which incorporates both technical and allocative efficiency of airports the empirical evidence confirms the theoretical predictions by revealing the following 1 airports are less productive in more corrupt environments and 2 airports tend to use more contracting out to replace in house labor in more corrupt environments the findings can be applied to the context of other public goods and have important policy implications for reforming governance structure of public good provision

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

the price of silence markets for noise licenses and airports this article presents a market design for the management of noise pollution created by aircraft traffic around airports a local market for noise licenses allows noise generators to compensate noise victims and to meet social acceptability we show that the market allows the market designer to implement the social planner s optimal allocation of flights as long as the latter does not put too high a weight in his her objective function on firms profits compared to the disutility of noise pollution the fact that local representatives of noise victims may be strategic players does not fundamentally alter this finding because of the market auctioneer s information constraints noise licenses are likely to distribute windfall gains to residents which alters the urban structure in the long run

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

estimating long run economic equilibria with stochastic trends an asymptotic theory is provided to analyze a menu of currently existing estimators of cointegrated systems we study in detail the single equation ecm seecm approach of hendry our theoretical results lead to prescriptions for empirical work such as specifying seecm s nonlinearly and including lagged equilibrium relationships rather than lagged differences of the dependent variable as covariates simulations support these prescriptions and point to problems of overfitting not encountered in the semiparametric approach of phillips and hansen 1990

is public capital really productive a methodological reappraisal abstract we present an evaluation of the main empirical approaches used in the literature to estimate the contribution of public capital stock to growth and private factors productivity based on a simple stochastic general equilibrium model built as to reproduce the main long run relations observed in us post war historical data we show that the production function approach may not be reliable to estimate this contribution our analysis reveals that this approach largely overestimates the public capital elasticity given the presence of a common stochastic trend shared by all non stationary inputs

why have measures of earnings quality changed over time the properties of earnings have changed dramatically over the past 40 years prior studies interpret this trend as a decline in earnings quality but disagree on whether it results from changes in the real economy or changes in accounting standards i find that each new cohort of listed firms exhibits lower earnings quality than its predecessors mainly because of higher intangible intensity i conclude that the trend of decline in earnings quality is due more to changes in the sample of firms than to changes in generally accepted accounting principles gaap or in the earnings quality of previously listed firms

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

changes in sectoral composition associated with economic growth in this paper the author uses dynamic general equilibrium methods to examine the interrelationship between sectoral composition and growth she shows that growth is affected by sectoral composition and vice versa the model is basically a solow model of sustained growth with multiple consumption goods and nonhomothetic preferences each consumption good is produced using different factor intensities the rate of exogenous technological change is different in each sector nonhomotheticity of preferences drives the result that sectoral composition affects growth rates copyright 1997 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

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

time to change your investment model we demonstrate empirically that the gains from predicting corporate earnings or consensus hits and misses an activity at the core of most investment methodologies have been shrinking fast over the past 30 years we identify the main reasons for this loss of earnings relevance and propose an improved alternative to current investment methodologies one that focuses on the strategic assets of the enterprise and their contribution to maintaining the company s competitive edge we demonstrate this investment methodology using subscription based companies

the role of airports in city employment growth 1950 2010 abstract this study considers the effects of commercial airports on local economies over the post world war ii period specifically 1950 2010 to overcome endogeneity concerns a pooled synthetic control event study strategy is employed on newly digitized historical aviation data to estimate treatment effects on a variety of employment population and wage outcomes i find that airports have led to on average 3 9 percent growth in total employment and 3 4 growth in population per decade over the 30 year period for which wage and air traffic data are available earnings per worker increased by 2 and per capita personal income increased by 3 corresponding to growth rates of up to 1 2 percent per decade respectively

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

public capital accumulation and private sector performance abstract this paper analyzes the effects of public capital on private sector variables in a vector auto regressive framework empirical results suggest first that public capital follows a policy rule that relates public capital positively with lagged output and negatively with lagged employment second public capital crowds in private capital while the long term effects on employment are only marginally positive finally a one dollar increase in public capital increases private output in the long term by 65 cents accordingly while public capital is productive its effects on output are much lower than claimed in the previous literature

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

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

understanding the economic performance of metropolitan areas in the united states examining the drivers of metropolitan economic performance this paper models two dependent variables change from 1990 to 2000 in gross metropolitan product and msa employment it is found that initial year economic structure an above average share of manufacturing employment agglomeration economies human capital share of population with bachelor degrees or higher and presence of state right to work laws are positively and significantly related to gmp and employment growth while the economic age of the area percentage of black non hispanic residents and average wage at the beginning of the period are negatively and significantly related to both the regional dummy variables commonly used to explain economic growth and typically highly significant are augmented by including climate related amenity business environment and economic age when these three variables are included in the model as independent variables with the regional dummy variables all three are significant for growth in gmp and

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

airport activity and local development evidence from italy the role of infrastructure as a factor of growth and development of countries and regions is often considered to be crucial among the various types of transport infrastructure airports are considered as particularly strategic because of the increasing importance of air transport in connecting territories this paper studies the impact of airports on italian provinces to this end it builds on the framework proposed by brueckner where sectoral employment is regressed on a series of controls and on airline traffic that framework is extended to take account of selection bias due to the location choices of airports and spatial spillover effects it is found that the elasticity of service sector employment to airport passengers is 0 045 and that of spillover effects due to neighboring airports is almost 0 017

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

how do you measure a technological revolution it is hardly news that we are in the midst of rapid economic change the advances in infor mation and communication technology ict in the life and other sciences and their profusion of innovative products from the newest electronic devices to the latest drugs and treatments are ample evidence equally pervasive are new busi ness models in services big box retail online banking on demand media and the explosion in social networking and new business practices ushered in by the internet telework virtual meetings job boards given the magnitude of the changes brought on by these innovations it is useful to step back and ask what does eco nomic analysis have to say about the sources and mechanisms of these shifts and revolutions and what economic metrics are available to measure their overall size and impact the received theory of economic growth is the natural candidate for this job it came of age in the 1950s and 1960s with the neoclassi cal models and emergence of aggregate growth accounting the latter has become the work horse of empirical macroeconomic growth analysis and the basis for official productiv ity statistics put out by the bureau of labor statistics bls since 1983 a technological revolution appears in this framework as an increase in the fruits of innovation as measured by the shift in an aggregate production function termed multifactor productivity or mfp and possibly as an increase in the aggregate saving rate as reflected in an increased rate of capital formation mfp is an exogenous phenomenon

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

infrastructure investment and canadian manufacturing productivity this paper examines the relationship between canadian public infrastructure and private output using a constant elasticity and substitution translog ces tl cost model to describe the interaction of the public and private sectors the ces tl was first specified by pollak et al 1984 we find public capital a substitute for private capital within the canadian manufacturing sector additionally the services of public capital enhance the productivity of private capital canadian manufacturing costs are characterized by economies of scale indicating that less than optimal plant sizes dominated canadian manufacturing sector during the study period advances in disembodied technical progress are also indicated

public capital and private productivity this paper uses three different approaches to investigate whether the declining provision of public capital is a major cause of declining labor productivity the juxtaposition of approaches removes

financial development and economic growth views and agenda this critique argues that the preponderance of theoretical reasoning and empirical evidence suggests a positive first order relationship between financial development and economic growth the body of work would push even most skeptics toward the belief that the development of financial markets and institutions is a critical and inextricable part of the growth process and away from the view that the financial system is an inconsequential sideshow responding passively to economic growth many gaps remain however and the paper highlights areas in acute need of additional research
