the disaggregated technology production function a new model of university and corporate research abstract technology and the process that produces it research and development r d are typically characterized as homogeneous entities in reality the typical industrial technology is composed of three elements a generic technology base supporting infratechnologies and proprietary market applications innovations the first two have public good characteristics and therefore explicitly modeling them is essential for public policy purposes the fundamental relationships among these elements require a technology production function that captures the supporting roles of the public good elements in creating proprietary applied technology these critical quasi public technology goods are supplied to a significant extent by exogenous external sources central corporate research labs government labs and increasingly universities the expanding university role beyond basic research complicates the structure and functioning of the national r d establishment and increases the need for a more accurate model of technological change to better inform r d policy moreover in assessing the resulting applied technology s impact on economic growth both the general and partial equilibrium literatures enter the technology variable into a production function with the common production assets physical capital and labor such models obscure an important distinction between technology and these production assets namely the fact that technology is primarily a demand shifting asset as such its role is correctly specified only when combined with the other major demand shifting asset marketing allocations to these two assets vary across competing firms implying a spatial model of competition while still providing traceability to the exogenous sources of public good technology elements such as universities

an empirical analysis of state and private sector provision of water services in africa under pressure from donor agencies and international financial institutions such as the world bank some developing countries have experimented with the privatization of water services this article reviews the econometric evidence on the effects of water privatization in developing economies and presents new results using statistical data envelopment analysis and stochastic cost frontier techniques and data from africa the analysis fails to show evidence of better performance by private utilities than by state owned utilities among the reasons why water privatization could prove problematic in lower income economies are the technology of water provision and the nature of the product transaction costs and regulatory weaknesses

privatisation in developing countries a review of the evidence and the policy lessons privatisation is widely promoted as a means of improving economic performance in developing countries however the policy remains controversial and the relative roles of ownership and other structural changes such as competition and regulation in promoting economic performance remain uncertain this article reviews the main empirical evidence on the impact of privatisation on economic performance in developing economies the evidence suggests that if privatisation is to improve performance over the longer term it needs to be complemented by policies that promote competition and effective state regulation and that privatisation works best in developing countries when it is integrated into a broader process of structural reform

technical performance and firm size analysis of patents and publications of u s firms this study focuses on the scientific output of firms of different sizes in different industries in the u s both patents and papers and publications are used as measures of technical output data from two samples of firms one consisting of 225 large firms annual sales at least 250 million and minimum annual r d budget of 1 million and the other consisting of 248 small and medium sized firms annual sales between 10 to 200 million and annual r d budget at least 10 thousand have been presented here the study shows that determinants of r d expenditure are different in firms of different sizes for the large firms r d expenditure depends on net income as well as its size measured in terms of annual sales for small size firms r d expenditure is closely related with sales rather than the net income for large firms r d expenditure is related to both sales and income the latter being more important than the former the two output measures patents and papers are correlated but the correlation is not a very strong one for small firms patent and papers are correlated significantly with both r d expenditure as well as annual sales the firm s growth is not linked with patents on the contrary there is a negative relationship between patent and r d growth and patent and income growth in the case of small firms papers are not linked with growth variables for small firms finally this study confirms the hypothesis that small firms are more productive in innovation than the large firms small firms are more efficient than their larger competitors in terms of patents and papers per million dollars of r d expenditure

political competition and policy adoption market reforms in latin american public utilities on y docencia econ omicas this article shows that political competition generates incentives that affect the pace of adoption of market reforms in the context of policy convergence previous work shows the effect of financial and technological pressures in promoting policy convergence and the impact of institutional constraints on shaping the pace of policymaking controlling for these effects this article demonstrates the policy effects of political competition and ideological polarization even at a time when ideological policy differences seem to be fading due to policy convergence this article studies policy adoption using duration analysis for the 18 countries of latin america during the 1985 2000 period when most of the market reforms in public utilities were adopted s tudies of market reforms in latin america have typically emphasized the common financial and technological pressures that limited the ability of incumbents to impose their ideological preferences on policy adoption during the 1980s and 1990s this article shows that although it is true that the ideology of incumbents cannot fully explain policy adoption political competition and the relative ideology of challengers did shape the incentives of policymakers and thus played a significant role in the adoption of market reforms the article shows these effects on the market reforms of latin american public utilities which have been widely regarded as an example of policy convergence market oriented reforms in telecoms and electricity including the privatization of assets the liberalization of markets and the separation of regulatory authority from operations spread rapidly around the globe and especially through latin america

competition marginal cost tariffs and spot pricing in the chilean electric power sector abstract setting up competitiveness and privatizing the power sector has been an important goal of chilean energy policy since 1974 the new organization of the electric sector includes deconcentration of generating and distributing companies a new marginal cost and spot pricing system coordination of generating companies through an economic load dispatching centre eldc and a scheme for sharing transmission lines this paper describes why and how those tasks were carried out in chile

demand for gasoline in kuwait an empirical analysis using cointegration techniques abstract this paper estimates the demand for gasoline in kuwait for the period 1970 1989 using a cointegration and error correction model ecm it is found that gasoline demand is inelastic with respect to price in the short and long run and while it is elastic in the long run gasoline demand is inelastic with respect to income in the short run this suggests that gasoline demand response to income changes is higher in the long run than in the short run furthermore gasoline consumption adjusts towards its long run level with about 52 of the adjustment occurring in the first year

the dynamics of technological innovation the sector of antibacterial medicines abstract this is an empirical and historical study of the dynamics of technological innovation in antibacterial medicines a key sector of the pharmaceutical industry it is based on an analysis of all the innovations that were introduced over the period 1935 1987 from prontosil the first sulphonamide through penicillin and the semisynthetic antibiotics to the monobactams and the quinolones of the mid 1980s in the historical section we describe the influence that antibacterial medicines have had on the structure and research intensity of the innovating companies and through them on the pharmaceutical industry and its geography we also describe the catalytic role played by government agencies and universities in the empirical section the innovations are evaluated in terms of originality and market performance and are classified into four technological trajectories their distribution over time and among technological trajectories companies and countries the relation between originality and market performance of individual innovations the interplay between social needs market demand and technological innovation the role of market successful radical innovations in the launching of technological trajectories the orientation of subsequent academic and industrial research and the establishment of corporate technology traditions provide insights in both innovation theory and the dynamics of technological innovation

sources of productivity growth in the spanish pharmaceutical industry 1994 2000 abstract the spanish pharmaceutical industry underwent an important transformation during the 1990s to survive under the new market conditions labs had to refocus their competitive strategies towards increasing productive efficiency or reinforcing research and development r d activities this paper analyzes the evolution of the productive patterns in a sample of 80 pharmaceutical laboratories that operated in spain from 1994 to 2000 we estimate malmquist productivity indexes and decompose them into four sources of productivity change the results suggest that pure technical efficiency change and the scale change of the technology explain most of the productivity growth observed during the period the contribution of technical change to productivity growth is negligible indicating a poor result from r d activities at least in the groups of small and medium sized labs

elasticities of demand for gasoline in canada and the united states abstract fluctuations in the world price of oil the concern with greenhouse gas emissions and the efforts to revive the 1997 kyoto protocol have resulted in renewed interest in the estimation of elasticities of demand for gasoline in this paper a complete system of demand equations is estimated including an equation for the demand for gasoline canadian family expenditure famex and united states consumer expenditure cex survey data are used household level data permits estimation of elasticities for various household groups also differences in demand responsiveness to own price and income changes are estimated for different regions in canada and the united states demand is found to be own price and income inelastic on the whole as reported in earlier studies there is also variation in these elasticities across regions of canada and the united states however larger differences are observed with respect to household size and housing tenure than to region of residence

a comprehensive review of the evolving and cumulative nature of eco innovation in the chemical industry different bodies of literature have attempted to explain what factors and events drive industries throughout processes of environmental change the latter is a gradual historical process of evolution from lower to higher degrees of development based on concepts derived from evolutionary economics greening technological progress and resource based view of the firm this article informs the sustainability transitions literature by providing an account of the evolution in the chemical industry s striving for the design use and production of environmentally sound chemical processes and products based upon eco innovation a conceptual model was elaborated depicting five stages of environmental change in the chemical industry in the period 1901 2030 the authors empirically tested this model by conducting a longitudinal computer aided content analysis of 255 documents addressing different environmental and innovation aspects in this industry in the same period of time the results of this article advance our modern understanding of the different stages of evolution of the chemical industry in terms of environmental change consistent with the conceptual model hitherto presented the findings of this article highlight a number cumulative of factors that enabled the evolution of the chemical industry throughout time supporting eco innovation highlighting the intertwined nature of regulation innovation and technological change it is plausible that the future development of this industry might be shaped by the policy driven paradigms of sustainability and resource efficiency 2015 the authors

infrastructure and public utilities privatization in developing countries should governments in developing countries promote private ownership and deregulated prices in noncompetitive sectors or should they run publicly owned firms and regulate prices at the expense of rents to insiders a theoretical model is used to answer these normative questions the analysis focuses on the tradeoff between fiscal benefits and consumer surplus during privatization of noncompetitive sectors privatization transfers control rights to private interests and eliminates public subsidies yielding benefits to taxpayers at the cost of increased prices for consumers in developing countries where budget constraints are tight privatization and price liberalization may be optimal for low profitability industries but suboptimal for more profitable industries and once a market has room for more than one firm governments may prefer to regulate the industry without a credible regulatory agency regulation is achieved through public ownership

the evolution of infrastructure and utility ownership and its implications the paper documents the significant changes of ownership since the infrastructure utilities were privatized and in particular the shifts from the initial focus on dispersed retail share ownership through takeovers to more concentrated ownership and the emergence of private equity and infrastructure funds in the process there has been substantial financial engineering and balance sheets have been geared up towards exhaustion with major implications for financing future investment increased gearing has on the one hand introduced the discipline of debt upon management which had engaged in substantive diversification and on the other provided an arbitrage between the weighted average cost of capital used to calculate the allowed return and the lower marginal cost of debt the paper shows how regulation has determined the allocation of risk and facilitated the observed changes in ownership and financial structures three solutions to the exhausted balance sheets are considered to finance future investment rate of return regulation the split cost of capital and a collapse back into not for dividend mutual or state ownership the default outcome already witnessed in the welsh water and network rail cases is the latter case which is inferior to the second option copyright 2009 oxford university press

the politics of foreign direct investment into developing countries increasing fdi through international trade agreements the flow of foreign direct investment into developing countries varies greatly across countries and over time the political factors that affect these flows are not well understood focusing on the relationship between trade and investment we argue that international trade agreements gatt wto and preferential trade agreements ptas provide mechanisms for making commitments to foreign investors about the treatment of their assets thus reassuring investors and increasing investment these international commitments are more credible than domestic policy choices because reneging on them is more costly statistical analyses for 122 developing countries from 1970 to 2000 support this argument developing countries that belong to the wto and participate in more ptas experience greater fdi inflows than otherwise controlling for many factors including domestic policy preferences and taking into account possible endogeneity joining international trade agreements allows developing countries to attract more fdi and thus increase economic growth

influencing factors on electricity demand in chinese nonmetallic mineral products industry a quantile perspective abstract chinese nonmetallic mineral products industry is one of the largest electricity consumer in china and has a large impact on overall electricity consumption in china this paper examines the impact of economic variables on the demand for electricity in chinese nonmetallic mineral products industry where economic growth sectoral value added per worker sectoral r d intensity and energy price were utilized to analyze sectoral electricity consumption with an application of quantile model the paper s estimates unveiled the varying effects of economic variables across the spectrum of sectoral electricity consumption where the coefficient of economic growth was positive and significant across all quantiles while sectoral value added per worker had both positive and negative significant coefficients an increase in income level and sectoral value added per worker will increase the electricity consumed by the industry however the latter will also enhance a decreasing trend in few regions across china and did not influence high energy efficiency but rather enhanced the production of additional outputs while sectoral r d intensity and energy price will ensure a substantial decrease in sectoral electricity consumption with the latter having a greater impact increase in investment for sectoral r d intensity will boost technological advancement and is recommended as a cornerstone to ensuring decline in sectoral energy consumption that will buttress sectoral value added per worker coupled with a robust energy price

knowledge sources patent protection and commercialization of pharmaceutical innovations abstract this paper investigates different types of innovations from radical to incremental in the pharmaceutical industry by studying bibliometric data of drugs approved by the united states food and drug administration fda looking at time to market aspects knowledge sources of these innovations and protection strategies scientific knowledge stemming from the public sector is found to be important for all innovations nevertheless radical innovations build on a higher degree on basic research and they build on a significantly higher share of own prior scientific research than do incremental innovations furthermore each drug is shown to be accompanied by on average about 19 journal publications and 23 additional patents additional patent filings peak when the commercialization of the drug is in reach firms do not differ among the various types of innovations regarding the amount of additional patent filings but rather with the speed of filing these patents finally this work contributes to the improvement of future econometric analyses that aim to link bibliometric indicators such as patent or publication counts to firm success

sectoral patterns of technical change towards a taxonomy and a theory abstract the purpose of the paper is to describe and explain sectoral patterns of technical change as revealed by data on about 2000 significant innovations in britain since 1945 most technological knowledge turns out not to be information that is generally applicable and easily reproducible but specific to firms and applications cumulative in development and varied amongst sectors in source and direction innovating firms principally in electronics and chemicals are relatively big and they develop innovations over a wide range of specific product groups within their principal sector but relatively few outside firms principally in mechanical and instrument engineering are relatively small and specialised and they exist in symbiosis with large firms in scale intensive sectors like metal manufacture and vehicles who make a significant contribution to their own process technology in textile firms on the other hand most process innovations come from suppliers these characteristics and variations can be classified in a three part taxonomy based on firms 1 supplier dominated 2 production intensive 3 science based they can be explained by sources of technology requirements of users and possibilities for appropriation this explanation has implications for our understanding of the sources and directions of technical change firms diversification behaviour the dynamic relationship between technology and industrial structure and the formation of technological skills and advantages at the level of the firm the region and the country

modeling energy demand some emerging issues abstract the proliferation of papers on energy demand modeling has offered different dimensions both in terms of methodology and estimation while this development has strengthened our understanding of the subject it may render the identification of gaps in the literature arduous for future research thus this study sets out to document some emerging issues that seem to have engendered new directions on energy demand modeling ranging from asymmetric price responses time varying demand parameters triangulation analyses to seasonal and climate change effects it is hoped that access to this review complemented with the previous ones will facilitate the comprehension of the extant literature as well as areas of future research in energy demand modeling

sub rosa resistance and the politics of economic reform land redistribution in post soviet ukraine this article examines obstacles to economic reform in ukraine s transition to a market based economy existing explanations for failures of reform in postcommunist states privilege societal actors as in the case of przeworski s j curve or state actors acting in a private rent seeking capacity as in hellman s partial reform equilibrium other explanations focus on weak state capacity however there is evidence to suggest that some groups of individuals who stall or halt market reforms may do so in their capacity as state actors their resistance to reform may be sub rosa state actors may comply with formal institutional requirements of reform even as they seek to preserve the status quo this tendency is evident in the privatization of land the focus of this article this article proposes an explanation for reform failures which suggests that some resistance to economic liberalization may derive from the efforts of state actors to protect the public good

how a symmetric is the response of import demand to changes in its determinants evidence from european energy imports abstract energy imports are crucial for european countries yet little is known about determinants of their import demand we update long outdated estimates of import demand elasticities using recent data for crude and derived energy products and contribute to the debate on the asymmetry of import demand by using recent developments in econometric modelling our results have important implications for the geopolitics of energy markets in europe asymmetric income seems to be the most relevant determinant of import demand economic growth and fossil fuel consumption are correlated even in the context of the european agenda towards renewables our results suggest that european economic recovery may derail the drive for lower fossil consumption and that changes in the natural gas market may further complicate this drive especially regarding russia as the primary supplier to the eurozone

infrastructure privatization and changes in corruption patterns the roots of public discontent abstract this paper offers a theory of how the degree of corruption that prevails in a society responds to changes in the ownership structure of major public service providers we show that there are cases in which privatization even though it fosters investments in infrastructure also opens the door to more corruption the public dissatisfaction towards privatization is then crucially affected by the changes in the degree and pattern of corruption our model thus helps understand the seemingly paradoxical situation prevailing in latin america where most studies find that privatizations have been efficiency enhancing and have fostered investments and at the same time popular dissatisfaction with the process is extremely high especially among the middle class we show that this line of explanation is consistent with the evidence from surveys in the region

how investor portfolios shape regulatory outcomes privatized infrastructure after crises summary many developing countries privatized utilities during the 1990s their weak institutional environments however make them prone to crises that generate incentives for governments to renege on contractual commitments to investors to understand variation in post crisis regulatory outcomes in such contexts scholars must consider investors prior choices regarding portfolio structure investors facing high reputational costs from exit are more likely to remain following expropriation and those holding diverse assets in their contract jurisdiction to secure compensation these factors account for significant unexplained within sector and subnational variation for which we provide qualitative and quantitative evidence from argentina s water and electricity sectors following the 2001 crisis

expert inquiry on innovation options for cleaner production in the chemical industry abstract the prospects of further progress in cleaner production in the chemical industry are explored by means of an expert inquiry which looks at the ecological and economic potentials of different technological and business innovation options as well as barriers to their development the outcome of the inquiry is analysed with a view to identify prospective priority areas for innovation support policies the analysis shows that innovation leading to alternative synthetic pathways and a shift to selling services instead of products have especially high potentials for both strong positive ecological effects and to be important factors for competitiveness the utilisation of these potentials depends however on whether different types of innovation barriers can be overcome suggestions are made as to how to develop policy measures to facilitate this

the future of uk final user energy demand anticipation of final user energy demand is central to suppliers and policy makers plans recent developments in dynamic econometrics such as the cointegration approach have enabled energy modellers to study long run relationships between demand and its determinants principally economic activity and real prices the purpose of this paper is to present the seecem output elasticity estimates and forecasts using the cointegration approach as well as the methodology and analysis underlying them as economic activity is expected to grow in all but the iron and steel sector the long run relationships indicate that most sectors will increase overall fuel use up to the year 2000 despite weak but potentially volatile world oil prices and given stable environmental policies average real oil prices should remain broadly constant except in the transport sector economic activity elasticities and increased competition in supply industries imply that natural gas and electricity are likely to take an increasing share of final user requirements at the expense of petroleum products and coal this gradual and continued shift towards cleaner fuels is likely to ameliorate adverse environmental consequences resulting from the overall growth in final user fuel demand

the influence of market demand upon innovation a critical review of some recent empirical studies abstract a number of recent empirical studies of technical change at the level of the individual firm have concluded that market demand is the dominant influence upon the innovation process calling forth innovations in market economies the pace of innovation in the private sector heavily influences the growth of national output and productivity and these studies and their conclusions have therefore received much attention having been extensively quoted in discussions of appropriate government policy for the encouragement of innovation this paper reviews a number of these studies and concludes that their findings and the interpretations of their findings in the secondary literature are seriously flawed and in many cases invalid the proposition that market demand governs the innovation process is by no means conclusively demonstrated in these studies and they are therefore inadequate and inappropriate guides for the formulation of policy most of the studies examined employ a working definition of demand factors which is so broad as to embrace a range of possible influences upon innovation which should more properly be classified elsewhere the concept of demand utilized in these studies bears little resemblance to the more restrictive and precise definition of market demand found in economics in addition the phenomena analyzed in these studies are a very heterogeneous lot the studies do not address identical empirical questions and their findings are as a result neither uniform nor unambiguous both demand and supply side influences are crucial to understanding the innovation process and it is the exclusive preoccupation with only one set of these forces which is criticized in this paper some implications of the criticism for government policy toward innovation are discussed in the conclusion

an empirical analysis of gasoline demand in denmark using cointegration techniques abstract danish time series data covering the period 1948 1991 are used in order to estimate short run and long run elasticities in gasoline demand a cointegration test for a stable long run relationship between the variables in the model proves to be positive showing a smaller value of the long run price elasticity than often quoted in empirical studies of gasoline demand finally an error correction model is estimated

gasoline consumption and the stock of motor vehicles an empirical analysis for the swiss economy abstract the demand for gasoline and the stock of cars is empirically explained for the swiss economy by applying statistical methods from modern time series analysis to annual data over the period 1962 1985 the short run price and income elasticities of gasoline consumption are 0 3 to 0 45 and 0 7 the price elasticity became substantially higher after the first opec shock in 1973 pollution control measures introduced in 1982 negatively affected the stock of cars longer run effects operating over changes in the size of the stock and the fuel efficiency of cars are stretched out over several years as shown by a variety of simulation experiments

empirical assessment of the determinants of road energy demand in greece this paper attempts to cast light on the determinants of road energy demand in greece for this purpose we used cointegration techniques and vector autoregression var analysis in order to capture short run and long run dynamics for gasoline and diesel demand respectively from the empirical analysis that covers the period 1978 2003 we find that in the long run gasoline energy demand appears to be price and income inelastic while diesel demand appears to be price inelastic and income elastic we also found that the absence of close substitutes in the road sector denotes the low level of energy switching in greece

cointegration and the demand for gasoline since the early 1970s there has been a worldwide upsurge in the price of energy and in particular of gasoline therefore demand functions for energy and its components like gasoline have received much attention however since confidence in the estimated demand functions is important for use in policy and forecasting following amarawickrama h a hunt l c 2008 electricity demand for sri lanka a time series analysis energy economics 33 724 739 this paper estimates the demand for gasoline is estimated with five alternative time series techniques with data from fiji estimates with these alternative techniques are very close and thus increase our confidence in them we found that gasoline demand is both price and income inelastic

federalism as a commitment to reserving market incentives the authors advance a new perspective in the study of federalism their approach views federalism as a governance solution of the state to credibly preserving market incentives market incentives are preserved if the state is credibly prevented from compromising on future economic success and from bailing out future failures the salient features of federalism decentralization of information and authority and interjurisdictional competition help provide credible commitment or these purposes in addition the authors suggest that some federalism are self sustaining

deterministic and stochastic trends in the time series models a guide for the applied economist applied economists working with time series data face a dilemma in selecting between models with deterministic and stochastic trends while models with deterministic trends are widely used models with stochastic trends are not so well known in an influential paper harvey 1997 strongly advocates a structural time series approach with stochastic trends in place of the widely used autoregressive models based on unit root tests and cointegration techniques therefore it is important to understand their relative merits this article suggests that both methodologies are useful and they may perform differently in different models this article provides a few guidelines to the applied economists to understand these alternative methods

the demand for gasoline in south africa an empirical analysis using co integration techniques abstract using the recently developed autoregressive distributed lag ardl bound testing approach to co integration suggested by pesaran et al pesaran m h shin y smith r j bounds testing approaches to the analysis of level relationships journal of applied econometrics 2001 16 3 289 326 we empirically analyzed the long run relationship among the variables in the aggregate gasoline demand function over the period 1978 2005 our study confirms the existence of a co integrating relationship the estimated price and income elasticities of 0 47 and 0 36 imply that gasoline demand in south africa is price and income inelastic

the dynamics of the liability of foreignness a global study of survival in financial services we study the impact of foreignness on survival in interbank currency trading worldwide over the period 1974 93 in particular we develop hypotheses on the behavior of the liability of foreignness over time and on the consequences of evolving sources of firm level competitive advantage on this liability we test these hypotheses on the population of 2667 market making trading rooms located in 47 countries worldwide that either existed in 1974 or entered the industry between 1974 and 1993 the results show that there is a liability of foreignness and that it changes over time further strategic and organizational factors such as the adoption of technology by these firms and their mode of internal control significantly influenced survival as did location related factors such as the intensity of local and foreign competition 1997 by john wiley sons ltd

strategic procurement openness and market structure abstract we examine strategic procurement behaviour by governments and its effect on market structure in sectors such as defence and pharmaceuticals where the government is the dominant consumer in a world economy with trade between producer countries and between producers and non producers we use a modified dixit stiglitz utility function with an independent taste for variety there is free entry and exit by firms but by anticipating their participation constraint governments can indirectly choose the number of domestic firms and their size through its choice of procurement price unlike the standard model with no independent taste for variety and no external sector of non producer countries there are incentives for subsidies openness impacts on industrial structure and procurement coordination between producer countries affects firm numbers

secure property as a bottom up process firms stakeholders and predators in weak states how do property rights become secure how does rule of law take hold in an economy the author uses an original survey of 516 firms in russia and ukraine as well as interview based case studies to reexamine these fundamental issues of political economy most states in the developing world lack the requisite time horizons and institutional capacity to make the credible commitments emphasized in the literature in this context the author argues that firms can enforce their property rights without resort to mafias by forming alliances with stakeholders such as foreign actors community residents and labor these stakeholders can impose costs on the potential aggressors through diverse political strategies allowing firms to defend their property rights not only from private predators but also from the state the article evaluates this bottom up theory of secure property rights against existing state based theorizing

the pitfalls of water privatization failure and reform in malaysia summary this paper examines why private participation in infrastructure ppi in water continues to be promoted despite poor results in developing countries it argues that the main characteristics of infrastructure discourage private investment and necessitate state subsidies which dilute private risks and incentives and facilitate rent seeking as a result ppi is characterized by public financing selective private investments and inconclusive efficiency gains this is reflected globally and in malaysia where ppi continues to be promoted because it provides captive rents the political factors that drive ppi invariably compromise institutional solutions as malaysia s water sector reforms illustrate

privatization technical efficiency and welfare consequences the case of the cote d ivoire electricity company cie abstract in 1990 cote d ivoire privatized the management of its electric power company lease contracting in this paper we are interested in identifying the economic effect of this institutional change by estimating a stochastic production frontier we have found that productive efficiency improved after privatization thanks to organizational innovations total factor productivity gains have been closely associated with a cost reduction strategy the way these gains have been distributed in a monopoly context suggests that consumers have been the main beneficiaries through a significant decrease of the relative price of electricity

sources of technical innovation in the network of companies providing chemical process plant and equipment abstract the purpose of this paper is to explore issues concerning technological innovation in the network of firms linked to the chemical industry with particular reference to the process plant contracting industry while technological and economic maturity inhibit the research and development activities of plant contractors little evidence was found of contractors adopting novel strategies to capture special advantage from technology developed by equipment manufacturing firms it is suggested that the changing economic and technological environment is creating a climate where new or closer contractor equipment manufacturer relationships should receive greater attention appropriate alliances between contractors and equipment manufacturers can not only help to reduce plant design procurement and erection costs but also offer a means to counter the competitive threat from more specialist firms in particular the large equipment manufacturers that possess their own project contracting skills furthermore collaboration in niche and technology fusion type innovation offers a means of generating scope for technological competitive advantage whilst sharing cost and risk whilst contractor equipment manufacturer alliances are one option the nature of the market demands operating company involvement to facilitate commercialisation

short and long run elasticities of gasoline demand in india an empirical analysis using cointegration techniques abstract in developing countries like india consumption of petroleum products has implications on its balance of payments economic growth and fiscal deficit gasoline is one of the prime petroleum products in this paper the relationship between gasoline demand national income and price of gasoline is empirically examined using cointegration and error correction techniques the time frame of the analysis is from 1972 1973 to 1993 1994 it has been found that gasoline demand is likely to increase significantly for a given increase in the gross domestic product the increase will be larger in the long run 2 682 than in the short run 1 178 gasoline demand is relatively inelastic to price changes both in the long and short terms the error correction model has shown that gasoline demand adjusts to their respective long run equilibrium at a relatively slow rate with about 28 of adjustment taking place in the first year

reversal of fortunes democratic institutions and foreign direct investment inflows to developing countries does increased democracy promote or jeopardize foreign direct investment fdi inflows to less developed countries we argue that democratic institutions have conflicting effects on fdi inflows on the one hand democratic institutions hinder fdi inflows by limiting the oligopolistic or monopolistic behaviors of multinational enterprises facilitating indigenous businesses pursuit of protection from foreign capital and constraining host governments ability to offer generous financial and fiscal incentives to foreign investors on the other hand democratic institutions promote fdi inflows because they tend to ensure more credible property rights protection reducing risks and transaction costs for foreign investors hence the net effect of democracy on fdi inflows is contingent on the relative strength of these two competing forces our argument reconciles conflicting theoretical expectations in the existing literature empirical analyses of fifty three developing countries from 1982 to 1995 substantiate our claims we find that both property rights protection and democracy related property rights protection encourage fdi inflows after controlling for their positive effect through property rights protection democratic institutions reduce fdi inflows these results are robust against alternative model specifications statistical estimators and variable measurements

the legal environment and incentives for change in property rights institutions summary land conflicts in many parts of the world indicate pressures for change in the property rights institutions governing land acquisition and land use whether or not institutional change occurs depends on the incentives and capacities of political actors this article argues that the legal environment is one factor influencing incentives for institutional change three case studies of land governance in southeast asia s palm oil industry illustrate three types of legal environment rule by law legalism legal pluralism and lawlessness or routinized illegality the cases show that the legal environment shapes modes of resistance to property reallocations in the palm oil industry rule by law legalism supports legalized modes of resistance through the court system in contrast legal pluralism and lawlessness favor the use of political strategies to contest property reallocations the mode of resistance in turn determines whether actors acquiring property have incentives to gain legal cover or whether investing in political resources is more rewarding although the effectiveness of resistance is largely determined by the distribution of political resources the mode of resistance helps explain whether there is demand for property rights institutions that offer generalized legal certainty in property protection path dependence arising from the legal environment therefore influences the direction of institutional change

elasticities of gasoline demand in switzerland abstract using cointegration techniques we investigate the determinants of gasoline demand in switzerland over the period 1970 2008 we obtain a very weak price elasticity of 0 09 in the short run and 0 34 in the long run for fuel demand i e gasoline plus diesel the corresponding price elasticities are 0 08 and 0 27 our rich dataset allows working with quarterly data and with more explicative variables than usual in this literature in addition to the traditional price and income variables we account for variables like vehicle stocks fuel prices in neighbouring countries oil shocks and fuel taxes all of these additional variables are found to be significant determinants of demand

privatization and renationalization what went wrong in bolivia s water sector summary this paper investigates the impact of water service privatization in bolivia it compares the performance of cities in which the service was privatized la paz and el alto with a city in which it is managed as a cooperative santa cruz de la sierra and one where the service is publicly provided cochabamba we find that access to water by low income consumers increased under private provision however the concessionaire failed to meet the targets stipulated in the contract the tariff increases required for full cost recovery eventually led to public outrage that forced the government to renationalize the company

short run long run and cross elasticities of gasoline demand in brazil gasoline is one of the most important of the oil derived products its importance is closely related to its participation in the value of imports of many countries and in a number of cases it is one of the determinants of their balance of payment deficit fiscal deficit and economic growth as opposed to most nations brazil has had a gasoline substitute since 1985 alcohol many studies have tried to estimate the income and price elasticities of the demand for gasoline in several countries this paper extends previous studies by estimating the cross price elasticity between gasoline and alcohol our findings indicate that alcohol is an imperfect substitute for gasoline even in the long run as a consequence the need for a new fuel substitution must be initiated long before petroleum reserves vanish

the dynamics of technological innovation the case of the pharmaceutical industry abstract this paper examines the mechanisms and dynamics of the process of innovation in companies and sectors of the chemical industry it is based on analysis of science and technology output indicators namely patents and innovations evaluated in terms of originality and in the case of innovations in terms of market success as well radical innovation ri is identified as the kingpin for the evolution of technologies in both the micro and macro economic context not only because it provides a model for imitation but also because it turns out to be more profitable for the innovating companies than incremental innovation at the micro economic level this paper examines the significance of diverse driving forces which lead a company to the launching of projects aiming at ri measures the length of commitment to such projects and describes the dynamic effects generated by the introduction of a successful ri and how they affect the company s subsequent r d and market orientation at the macro economic level this paper identifies the stages of youth growth maturity and decline of the subsectors of the chemical industry examines the distribution of ri and market successful innovations over the development of a sector describes the influence of market demand and capital investment on technological advance and compares the development of national chemical industries the paper concludes with an account of the dynamics of technological innovation in the chemical industry over the period 1930 1985 which is based on the empirical findings of the previous sections

international investment agreements and services markets locking in market failure summary bilateral investment treaties bits and investment chapters in preferential trade agreements have become popular measures to guarantee investor friendly policies while they reassure multinational firms they also constrain host country authorities in regulating markets to stimulate competition these problems are widespread in service industries characterized by significant economies of scale this paper presents case studies of the difficulties the chilean regulatory authorities faced in regulating the financial services telecom and energy industries it concludes that able regulators are necessary but that international agreements need to also leave enough policy space

regulation institutions and commitment in telecommunications a comparative analysis of five country studies within any system of utility regulation there is a tension between the ability to commit to a stable set of rules and the ability to respond flexibly to changing circumstances countries differ in their institutional endowments and hence in the ways in which they can resolve this tension a first group of countries can design regulatory systems that afford the regulator substantial formal discretion to respond to changing circumstances and can use process to restrain arbitrary action a second group of countries can restrain arbitrary action only by calling on specific substantive rules and may have to sacrifice some flexibility to achieve credible commitment a third group may lack the domestic institutions to put in place a credible and workable regulatory system of any kind

economic perspectives on privatization despite being one of the most fundamental issues in political economy the question of the appropriate boundary between public and private enterprise received relatively little attention in mainstream economic analysis until quite recently in the 1980s however programs of ownership reform were started in many developed and developing countries dramatic though some of these policies have been they are likely to be overshadowed in the 1990s by even greater privatization in the reforming socialist economies the opening sections of this paper are organized around three broad and interrelated questions how does ownership matter for the efficiency of enterprise performance what is the role for privatization in financing public debts and deficits what are the distributional and political implications of privatization finally we examine privatization in practice in three countries britain chile and poland

the performance of privatised enterprises in developing countries abstract privatisation has been advocated as the predominant way to solve the problems facing ailing public enterprises in developing countries despite this the policy remains controversial the available empirical evidence on the operational and financial performance of enterprises after privatisation has often painted a rosy picture this paper reassesses the situation using a larger sample of enterprises and a comparative perspective between privatised utilities non utilities and private enterprises that have never been state owned the results of our analysis point to there being differences in the performance across the three groups of enterprises and in particular to a deterioration in performance among privatised utilities this suggests that the earlier optimism over the efficacy of privatisation may have been premature

competing for capital the diffusion of bilateral investment treaties 1960 2000 over the past forty five years bilateral investment treaties bits have become the most important international legal mechanism for the encouragement and governance of foreign direct investment the proliferation of bits during the past two decades in particular has been phenomenal these intergovernmental treaties typically grant extensive rights to foreign investors including protection of contractual rights and the right to international arbitration in the event of an investment dispute how can we explain the widespread adoption of bits we argue that the spread of bits is driven by international competition among potential host countries typically developing countries for foreign direct investment we propose a set of hypotheses that derive from such an explanation and develop a set of empirical tests that rely on network measures of economic competition as well as more indirect evidence of competitive pressures on the host to sign bits the evidence suggests that potential hosts are more likely to sign bits when their competitors have done so we find some evidence that coercion and learning play a role but less support for cultural explanations based on emulation our main finding is that the diffusion of bits is associated with competitive economic pressures among developing countries to capture a share of foreign investment we are agnostic at this point about the benefits of this competition for development for useful comments on earlier drafts of this article we thank bill bernhard bear braumoeller frank dobbin robert franzese jeffry frieden geoffrey garrett tom ginsburg jude hays lisa martin bob pahre mark ramsayer steven ratner susan rose ackerman and john sides for research assistance we thank elizabeth burden raechel groom and alexander noonan

institutional causes macroeconomic symptoms volatility crises and growth countries that have pursued distortionary macroeconomic policies including high inflation large budget deficits and misaligned exchange rates appear to have suffered more macroeconomic volatility and also grown more slowly during the postwar period does this reflect the causal effect of these macroeconomic policies on economic outcomes one reason to suspect that the answer may be no is that countries pursuing poor macroeconomic policies also have weak institutions including political institutions that do not constrain politicians and political elites ineffective enforcement of property rights for investors widespread corruption and a high degree of political instability this paper documents that countries that inherited more extractive institutions from their colonial past were more likely to experience high volatility and economic crises during the postwar period more specifically societies where european colonists faced high mortality rates more than 100 years ago are much more volatile and prone to crises based on our previous work we interpret this relationship as due to the causal effect of institutions on economic outcomes europeans did not settle and were more likely to set up extractive institutions in areas where they faced high mortality once we control for the effect of institutions macroeconomic policies appear to have only a minor impact on volatility and crises this suggests that distortionary macroeconomic policies are more likely to be symptoms of underlying institutional problems rather than the main causes of economic

coordination commitment and enforcement the case of the merchant guild we interpret historical evidence in light of a repeated game model to conclude that merchant guilds emerged during the late medieval period to allow rulers of trade centers to commit to the security of alien merchants the merchant guild developed the theoretically required attributes secured merchants property rights and evolved in response to crises to extend the range of its effectiveness contributing to the expansion of trade during the late medieval period we elaborate on the relations between our theory and the monopoly theory of merchant guilds and contrast it with repeated game theories that provide no role for formal organization

invention and innovation in the chemical industry demand pull or discovery push abstract this paper describes a study of the determinants of the rate direction and scale of inventive and innovative activity in the chemical industry over the period 1830 1980 statistical data are interpreted in the light of case study material in three major sectors dyestuffs plastics and pharmaceuticals theories of technical change and economic growth particularly those of schmookler and schmpeter are examined in relation to this material on the chemical industry the findings suggest that the importance of demand pull and discovery push factors and the validity of schmookler s and schumpeter s theories vary over an industry s life cycle

does basic services privatisation benefit the urban poor some evidence from water supply privatisation in thailand access to safe water and sanitation has been a development priority for decades this is also included in the millennium development goal targets meanwhile privatisation of water supply continues to be a subject of intense debate particularly as to its effects on the urban poor the arguments for and against often reflect the intellectual divide between socialist ideals and neo liberal pragmatism key issues are access quality and price this paper reports findings from an investigation of thailand s first water supply privatisation scheme implemented in 1998 household level data for the poor defined by community and income status show a significant improvement in access to piped water despite an increase in the connection cost and monthly charges the associated benefits from access include improved water quality and service a promising plus is the prospect of improvement in tenure status for the households living in informal settlements

crisis and policymaking in latin america the case of chile s 1998 99 electricity crisis summary this article studies the effect of sectoral crises on policy reform by emphasizing the conflictive incentives generated by public demands for a solution on the one hand the crisis provides the opportunity for bypassing veto points for technical innovation on the other hand if simultaneous with increasing electoral competition it reduces the time horizons of policymakers and their propensity to adopt reforms of uncertain effects for them our research traces these on the chilean 1998 99 electricity crisis and assesses their impact on policy change through a comparative analysis of reform contents this article shows how electoral effects prevailed in the context of upcoming competitive elections suggesting the importance of introducing electoral competition in the study of crises effects on policymaking in the region our research strategy for tracing incentives and opportunities generated by crises can travel to other cases to further our understanding of crises effects on policymaking

a theory of privatisation public enterprises around the world have proved to be highly inefficient primarily because they pursue strategies such as excess employment that satisfy the political objectives of politicians who control them privatization of public enterprises can raise the cost to politicians of influencing them since subsidies to private firms necessary to force them to remain inefficient are politically harder to sustain than wasted profits of the state firms in this way privatization leads to efficient restructuring of firms moreover privatization is more effective when combined with a tight monetary policy and when the new owners of firms are profit maximizing investors rather than their employees or even managers copyright 1996 by royal economic society

original sin good works and property rights in russia are property rights obtained through dubious means forever tainted with original sin or can right holders make their ill gotten gains legitimate by doing good works this is a critical question for developing and transition countries where privatization is often opaque and businesspeople may receive property but remain unwilling to use it productively due to concerns about the vulnerability of their rights to political challenge using a survey of 660 businesspeople conducted in russia in 2005 the author finds that the original sin of an illegal privatization is difficult to expunge contrary to a coasian view of privatization property rights transferred through a legally questionable privatization are seen as illegitimate long after privatization businesspeople however can improve the legitimacy of property rights by doing good works such as providing public goods and using their assets well finally managers who provide public goods for their region are more likely to invest in their firms than those who do not this suggests a possible political rationale for the provision of public goods by private firms these findings have implications for studies of privatization property rights and business state relations in transitions and developing countries

regulation of privatized utilities the chilean experience abstract the privatization of chile s public utilities has led to substantial new investment and improvements in internal efficiency however the limited information available to regulators combined with their insufficient technical capacity have combined to prevent efficiency increases being fully passed on to consumers in price reductions in fact drastic price cuts have occurred only where competition has emerged so achieving competition wherever possible should be the main policy goal competition can be enhanced by either modifying existing regulations as happened in long distance telecommunications or by a more active antitrust policy to achieve this the regulatory institutions clearly need strengthening

the duality of collaboration inducements and opportunities in the formation of interfirm linkages i argue that the linkage formation propensity of firms is explained by simultaneously examining both inducement and opportunity factors drawing upon resource based and social network theory literatures i identify three forms of accumulated capital technical commercial and social that can affect a firm s inducements and opportunities to form linkages firms possessing these capital stocks enjoy advantages in linkages formation however firms lacking these accumulated resources can still form linkages if they generate a radical technological breakthrough thus i identify paths to linkage formation for leading as well as peripheral firms i test these arguments with longitudinal data on technical collaborative linkages in the global chemicals industry copyright 2000 john wiley sons ltd

businesspeople in elected office identifying private benefits from firm level returns do businesspeople who win elected office use their positions to help their firms business leaders become politicians around the world yet we know little about whether their commitment to public service trumps their own private interests using an original dataset of 2 703 firms in russia i employ a regression discontinuity design to identify the causal effect of firm directors winning seats in subnational legislatures from 2004 to 2013 first having a connection to a winning politician increases a firm s revenue by 60 and profitability by 15 over a term in office i then test between different mechanisms finding that connected firms improve their performance by gaining access to bureaucrats and not by signaling legitimacy to financiers the value of winning a seat increases in more politically competitive regions but falls markedly when more businesspeople win office in a convocation politically connected firms extract fewer benefits when faced with greater competition from other rent seekers

financialisation and the slowdown of accumulation over the past decades financial investment of non financial businesses has been rising and accumulation of capital goods has been declining the first part of the paper offers a novel theory to explain this phenomenon financialization the shareholder revolution and the development of a market for corporate control have shifted power to shareholders and thus changed management priorities leading to a reduction in the desired growth rate in the second part the link between accumulation and financialization is tested econometrically by means of a time series analysis of aggregate business investment for usa uk france and germany extensive test of robustness are performed for the first three countries evidence that confirms the negative effect of financialization on accumulation is found author s abstract

a study of innovation in the pesticide industry analysis of the innovation record of an industrial sector abstract this is a study of innovation in pesticides from 1930 to 1980 innovation output indicators used are product innovation and patent counts innovations are evaluated in terms of originality and market success market demand is measured by the value of sales per year at constant prices the distribution of these indicators over the 50 year period is compared and contrasted to the historical development of the sector a number of hypotheses are proposed regarding the dynamics of the process of innovation notably the importance of market successful radical innovations as driving forces the central role of large research intensive companies the interplay between basic and applied research and the effects of corporate technological traditions lastly the potential and some limitations in the use of patents as innovation output indicators are described

market government and malaysia s new economic policy leading economic institutions such as the world bank have argued that liberalisation holds the key to growth poverty alleviation and redistribution even recent efforts to model increasing returns within the framework of new growth theories have not resulted in prescriptions for stronger roles for governments the fast growing southeast asian economies are still being used to demonstrate causation between liberalisation and growth poverty alleviation and redistribution using malaysia as an example this paper argues that growth poverty alleviation and redistribution in the country was achieved under circumstances of both interventionist policies as well as market coordination throughout the new economic policy nep period 1970 90 strong incentives were offered to both the import substitution and exportoriented manufacturing sectors and the state made strong forays into the market to redress poverty and inequality the paper also argues that poorly coordinated government intervention generated substantial unproductive rent seeking

a unified model of cabinet dissolution in parliamentary democracies the literature on cabinet duration is split between two apparently irreconcilable positions the attributes theorists seek to explain cabinet duration as a fixed function of measured explanatory variables while the events process theorists model cabinet durations as a product of purely stochastic processes in this paper we build a unified statistical model that combines the insights of these previously distinct approaches we also generalize this unified model and all previous models by including 1 a stochastic component that takes into account the censoring that occurs as a result of governments lasting to the vicinity of the maximum constitutional interelection period 2 a systematic component that precludes the possibility of negative duration predictions and 3 a much more objective and parsimonious list of explanatory variables the explanatory power of which would not be improved by including a list of indicator variables for individual countries

credible commitment and property rights evidence from russia most managers said that state arbitration courts did not work badly in disputes with other businesses but few expected these courts to protect their rights in disputes with state officials more importantly managers who expressed confidence that state arbitration courts could constrain state officials invested at higher rates even controlling for the perceived effectiveness of state institutions thus tightening constraints on state agents can increase the security of property and bolster state capacity these results generate insights into debates on the role of state in the economy the origins of secure property rights the nature of state capacity the importance of informal institutions and the process of legal reform

a co integration analysis of the price and income elasticities of energy demand in turkish agriculture abstract agriculture has an important role in every country s development particularly the contribution of agriculture to development and competitiveness is increasing with agricultural productivity growth productivity in turn is closely associated with direct and indirect use of energy as an input therefore the importance of energy in agriculture cannot be denied as one of the basic inputs to the economic growth process following the importance of energy in turkish agriculture this study aims to estimate the long and short run relationship of energy consumption agricultural gdp and energy prices via co integration and error correction ecm analysis annual data from 1970 to 2008 for diesel and electricity consumptions are utilized to estimate long run and short run elasticities according to ecm analysis for the diesel demand model the long run income and price elasticities were calculated as 1 47 and 0 38 respectively for the electricity demand model income and price elasticities were calculated at 0 19 and 0 72 respectively in the long run briefly in turkey support for energy use in agriculture should be continued in order to ensure sustainability in agriculture increase competitiveness in international markets and balance farmers income

the political economy of the pharmaceutical industry e conomicsis a practical science since its inception as an independent discipline it has probed the major policy issues of the day the topics that aroused the interests of its practitioners have generally been those that presented government officials with critical choices the modern literature on the economics of the pharmaceutical industry is no exception this body of material originated with the investigations of the kefauver committee in late 1959 public interest was aroused by the spectacle of confrontation between committee and industry the record made by this committee and its successors grew to tens of thousands of pages as claims and counterclaims were offered regarding industry conduct and performance the primary line of attack concerned pharmaceutical prices and profits the committee demonstrated that prices generally exceeded direct costs of manufacturing for 22 major pharmaceutical firms in 1958 costs of goods sold were merely 32 percent of total sales u s senate report 1961 p 31 the committee argued that this fact alone demonstrated the presence of monopoly power while the substantial difference between revenues and production costs permitted high expenditures on research and development it also paid for even higher selling outlays moreover reported rates of return after taxes during this period on the order of 21 to 22 percent exceeded twice the average for all manufacturing the industry replied that on the contrary prices were low relative to the value afforded consumers and high returns on successful products were required to balance the losses from the large numbers of unsuccessful ones the relevant concept of marginal costs according to the industry position must include the costs of developing and marketing new products and therefore prices were not excessive at all although it admitted earning substantial profits the industry argued that without these returns research outlays would be limited and the number of new drugs reduced the committee countered that little of social value arose from industry research molecules were manipulated and the new drugs that resulted were therapeutically similar to those already on the market indeed it suggested that much
