efficiency and equalization payments in a federal system of government a synthesis and extensions of recent results this paper investigates the rationale for a system of equalization transfers in a federal system of government the existing sources of inefficiency of resource allocation in economies with more than one level of government are synthesized in the framework of a simple decentralized multiprovince model with mobile factors of production the sources of inefficiency arise first because migrants respond at the margin to incorrect signals owing to the phenomena of rent sharing and fiscal exterality and second because of global rather than local inefficiencies the model is then extended to consider the role of the federal government in providing intergovernmental transfers in the face of such inefficiencies in addition to synthesizing the sources of inefficiency in federal models the equity arguments for equalization are briefly recounted efficacite et paiements de perequation dans un systeme federal de gouvernement synthese et extensions de certains resultats recents ce memoire examine la logique qui soustend un systeme de paiements de perequation dans un systeme fdderal de gouverement les auteurs utilisent un modele simple d un systeme multi provincial decentralise avec des facteurs de production mobiles pour definir les sources d inefficacite dans l allocation des ressources dans les dconomies qui possedent plus d un niveau de gouvernement ces inefficacites proviennent de ce que d abord ceux qui se deplacent le font en reponse a la marge a des signaux incorrects engendres par le partage de la rente sur la base de la residence et par les phenomenes d exteralites fiscales elles sont aussi le resultat d inefficacites globales plutot que locales dans le cadre de ce modele les auteurs analysent le role du gouvernement federal effectuant des transferts inter gouverementaux pour corriger ces inefficacites en plus de presenter une synthese des sources d inefficacite dans les regimes federaux les auteurs font un bref rappel en passant a l ensemble des arguments fondes sur l equite qu on utilise pour rationaliser les paiements de perequation this paper is a linear combination of two papers presented at the may 1982 meetings of the canadian economics association in halifax entitled the case for equalization payments by the authors and recent developments in the theory of regional economic policy in canada by boadway the authors are grateful for comments by the discussants jim johnson and baxter macdonald and by jack mintz brian scarfe gerard belanger david sewell tom courchene and the referees we are especially heavily indebted to dan usher for many stimulating comments and suggestions while the work was in progress some of the above persons will undoubtedly disagree with the emphasis we have chosen to put on various aspects of the analysis for policy purposes support for some of this work has been provided by the economic council of canada and is gratefully acknowledged canadian journal of economics revue canadienne d economique xv no 4 november novembre 1982 printed in canada imprimd au canada 0008 4085 82 0000 0613 01 50 1982 canadian economics association this content downloaded from 207 46 13 127 on wed 12 oct 2016 04 27 47 utc all use subject to http about jstor org terms 614 robin boadway and frank flatters

does entry size matter the impact of the life cycle and technology on firm survival a wave of empirical studies has recently emerged showing that smaller scale entry is confronted with a lower likelihood of survival than their larger counterparts the purpose of this paper is to examine whether the relationship between size of a firm when entering an industry and the likelihood of survival holds under different technological conditions and across the different stages of the industry life cycle the empirical evidence suggests that the relationship between firm size and the likelihood of survival is shaped by technology and the stage of the industry life cycle while the likelihood of survival confronting small entrants is generally less than that confronting their larger counterparts the relationship does not hold for mature stages of the product life cycle or in technologically intensive products in mature industries that are still technologically intensive entry may be less about radical innovation and possibly more about filling strategic niches thus negating the impact of entry size on the likelihood of survival

characterizing the technology firm an exploratory study abstract technology firms occupy a central position in modern economies they drive economic growth productivity gains and have created new industries and innovative products many will agree that technology firms are distinguished from others in their emphasis on technological activities since this observation is too general researchers suggested a variety of specific criteria and definitions a number of definitions of technology firms appear in the literature but many are arbitrary and simplistic and none gained wide acceptance similarly the number of characteristics suggested is large reflecting a variety of perspectives and interests in this case too no agreement exists as to which are the important ones also many seem to be interrelated capturing different aspects of the same underlying concepts this paper is concerned with the issue of definition and classification of technology firms we demonstrate the usefulness of a different approach to the definition and classification problem we rely on executives evaluations of their firms technology profile and level an analysis of these evaluations reveals the underlying dimensions the executives used in making their judgments we regard the dimensions we uncover as capturing the essence of technology firms and use them to classify the firms we study the specific characteristics the executives used to evaluate their firms were derived from a systematic scan of the literature thus the list represents the set of characteristics early researchers viewed as describing and defining technology firms the connection to early work enhances our findings validity and lends some credence to our belief that the three dimensions we uncover r d activities which are closely associated with a set of organizational elements and market conditions product strategy and corporate culture can be used by others to define technology firms and classify firms according to their technology level in our study we use these three dimensions to classify the firms studied we show that the commonly used practice of classifying firms as high and low technology according to the industry to which they belong is flawed our goal in this study is not to offer a new or better definition and characterization of technology firms or to offer the best approach to the generation of the classification criteria rather we demonstrate here the usefulness of a different approach to the problem while our approach does suffer from limitations it has important advantages we hope future studies will confirm not only the usefulness of our approach but also the general applicability of the specific criteria we identify in this study

endogenous federal grants and crowd out of state government spending theory and evidence from the federal highway aid program contrary to simple theoretical predictions existing evidence suggests that federal grants do not crowd out state government spending a legislative bargaining model with endogenous grants documents a positive correlation between grant receipts and preferences for public goods this correlation has likely biased existing work against measuring crowd out to correct for such endogeneity the model motivates instruments based on the political power of state congressional delegations exploiting this exogenous variation in grants the instrumental variables estimator reports crowd out that is statistically and economically significant this endogeneity may explain the flypaper effect a nonequivalence between grant receipts and private income jel d70 h40 h77

exchange rate return predictability and the adaptive markets hypothesis evidence from major foreign exchange rates this study examines return predictability of major foreign exchange rates by testing for martingale difference hypothesis mdh using daily and weekly nominal exchange rates from 1975 to 2009 we use alternative mdh tests for linear and nonlinear dependence which include wild bootstrap automatic variance ratio test generalized spectral test and consistent tests we evaluate time varying return predictability by applying these tests with fixed length moving sub sample windows of two years while exchange rate returns are found to be unpredictable most of times we do observe episodes of statistically significant return predictability they are associated with coordinated central bank interventions and the subprime mortgage crisis in 2007 this finding suggests that return predictability of foreign exchange rates occurs from time to time depending on changing market conditions which is consistent with the implications of the adaptive markets hypothesis

the estimation of human capital by administrative archives in a static and longitudinal perspective the case of milan this paper focuses on the estimation of the latent variable human capital hc at disaggregated level worker by available routinely institutional data flows in particular we utilize the lombardy region administrative archive employment centers of the province of milan collecting information about careers of workers in the private sector of the milan area and administrative flows collecting mandatory workers individual income tax returns filed with the national internal revenue service first we propose and empirically estimate hc scores in a static referred to 2004 framework by means of a realistic measurement model within causal relationships among endogenous and exogenous investment hc indicators furthermore the model also specifies a set of concomitant indicators that not belonging to hc investment indicators have causal impact on endogenous variables and on hc scores too second we propose a longitudinal analysis period 2000 2004 aimed to investigate how workers earned income growth rates vary over workers educational levels and other personal characteristics the empirical results of both analyses confirm the characteristics of the italian job market denoted by marked inequalities and knowledge regarding the process of school to work transition characterized by a weak incidence of education on longitudinal trajectories of earned income

the incentive effect of fiscal equalization transfers on tax policy abstract a theoretical analysis considers the impact of a typical system of redistributive fiscal equalization transfers on the tax effort of local jurisdictions more specifically it shows that the marginal contribution rate i e the rate at which an increase in the tax base reduces those transfers might be positively associated with the local tax rate while the volume of grants received is likely to be inversely related to the tax rate these predictions are tested in an empirical analysis of the tax policy of german municipalities in order to identify the incentive effect the analysis exploits discontinuities in the rules of the fiscal equalization system as well as policy changes the empirical results support the existence of an incentive effect suggesting that the high marginal contribution rates induce the municipalities to set significantly higher business tax rates compared with a situation without fiscal equalization

inter industry technology flows in the united states abstract this paper presents for the u s economy a technology flows matrix tracing 1974 industrial r d expenditures from their industries of origin to industries in which the use of resulting products and processes was anticipated the distinction between origin and using industries is crucial to understanding the links between r d and productivity growth a regression analysis reveals high social rates of return and substantial productivity impacts from r d attributed to industries of use

testing the endogenous growth model public expenditure taxation and growth over the long run endogenous growth models such as barro 1990 predict that government expenditure and taxation will have both temporary and permanent effects on growth we test this prediction using panels of annual and period averaged data for oecd countries during 1970 95 isolating long run from short run fiscal effects our results strongly support the endogenous growth model and suggest that long run fiscal effects are not fully captured by period averaging and static panel methods unlike previous investigations our estimates are free from biases associated with incomplete specification of the government budget constraint and do not appear to result from endogeneity of fiscal or investment variables jel classification h30 o40 validation du modele de croissance endogene depenses publiques fiscalite et croissance a long terme des modeles de croissance endogene comme celui de barro 1990 predisent que depenses gouvernementales et fiscalite vont avoir des effets temporaires et permanents sur la croissance on met cette prevision au test a l aide de donnees annuelles et pour certaines moyennes couvrant des sous periodes pour les pays de l ocde 1970 95 dans le but de departager les effets a court et a long terme les resultats valident fortement le modele de croissance endogene et suggerent que les effets fiscaux a long terme ne sont pas pleinement captures par des methodes utilisant des moyennes ou des methodes statiques contrairement aux resultats d enquetes anterieures les resultats proposes ne souffrent pas de distorsions attribuables a une specification incomplete de la contrainte budgetaire du gouvernement et ne semblent pas etre l effet d echo de l endogeneite des variables fiscales et de l investissement

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

using a discontinuous grant rule to identify the effect of grants on local taxes and spending when investigating the effects of federal grants on the behavior of lower level governments it is hard to defend the handling of grants as an exogenous factor federal governments often set grants based on characteristics and performance of decentralized governments in this paper we make use of a discontinuity in the swedish grant system in order to estimate the causal effects of general intergovernmental grants on local spending and local tax rates the formula for the distribution of funds is used as an exclusion restriction in an iv estimation we find evidence of crowding in where federal grants are shifted to more local spending but not to reduced local tax rates

price delay and market frictions in cryptocurrency markets abstract we study the efficiency of cryptocurrencies by measuring the price s reaction time to unexpected relevant information we find the average price delay to significantly decrease during the last three years for the cross section of 75 cryptocurrencies we find delays to be highly correlated with liquidity

optimal vs naive diversification in cryptocurrencies abstract this paper contributes to the literature on cryptocurrencies by examining the performance of naive 1 n and optimal markowitz diversification in a portfolio of four popular cryptocurrencies we employ weekly data with weekly rebalancing and show there is very little to select between naive diversification and optimal diversification our results hold for different levels of risk aversion and an alternative estimation window

the inefficiency of bitcoin revisited a dynamic approach abstract this letter revisits the informational efficiency of the bitcoin market in particular we analyze the time varying behavior of long memory of returns on bitcoin and volatility 2011 until 2017 using the hurst exponent our results are twofold first r s method is prone to detect long memory whereas dfa method can discriminate more precisely variations in informational efficiency across time second daily returns exhibit persistent behavior in the first half of the period under study whereas its behavior is more informational efficient since 2014 finally price volatility measured as the logarithmic difference between intraday high and low prices exhibits long memory during all the period this reflects a different underlying dynamic process generating the prices and volatility

return and volatility spillovers among cryptocurrencies abstract this paper measures interdependencies among 18 major cryptocurrencies and shows that i bitcoin is the dominant contributor of return and volatility spillovers among all the sampled cryptocurrencies ii return and volatility spillovers have risen steadily over time iii there are spikes in spillovers during major news events regarding cryptocurrencies these findings suggest growing interdependence among cryptocurrencies and by extension a higher degree of contagion risk it may be the case that cryptocurrencies are becoming more integrated albeit this makes for interesting future empirical testing in addition the time varying nature of spillovers reveals a certain dimension of uncertainty regarding the future of these digital currencies

fiscal policy elastic labor supply and endogenous growth abstract endogenizing labor supply leads to fundamental changes in the equilibrium structure of the ak growth model the balanced growth equilibrium can be described in terms of two tradeoff loci relating the equilibrium growth rate to the fraction of time devoted to leisure the implications of endogenous labor supply for fiscal policy are analyzed three issues are addressed first the effects of various distortionary tax changes and government expenditure changes on the equilibrium growth leisure employment tradeoff are analyzed second optimal fiscal policy is characterized finally the formal analysis is supplemented by numerical results focusing particularly on the quantitative welfare implications

adaptive market hypothesis and evolving predictability of bitcoin abstract this study evaluates the adaptive market hypothesis amh and evolving return predictability in bitcoin market we use two robust methods in a rolling window framework to capture time varying linear and nonlinear dependence in bitcoin returns we find that market efficiency evolves with time and validates the amh in bitcoin market

liquidity uncertainty and bitcoin s market microstructure abstract this paper provides a novel measure of liquidity uncertainty for bitcoin using bid ask spread data from bitfinex one of the largest and most liquid bitcoin exchanges this measure can be used to analyze liquidity developments in bitcoin exchanges or to gauge the immediacy associated with buying or selling bitcoin it then proceeds to identify what aspects of bitcoin s market microstructure can explain the time series behavior of this liquidity uncertainty the estimation results are based on a markov regime switching model that captures episodes of high and low liquidity uncertainty for bitcoin over the period from october 2013 to march 2018

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

impact on firms of the use of knowledge external sources a systematic review of the literature this study summarizes the main conclusions from a systematic review of the empirical literature regarding the impact on firms of the use of knowledge external sources universities research institutes and knowledge intensive business services with the aim to organize the literature we classify the different works according to the research question addressed i which firms use knowledge external sources ii do firms using knowledge external sources achieve better results and iii which firms benefit the most from using knowledge external sources stylized facts are that larger more r d intensive and high tech firms are more likely to use knowledge external sources and that use of knowledge external sources is associated to firms higher technical results less attention has been paid to the third question and evidence is not conclusive several recommendations for future research emerge first to take in greater consideration methodological issues so that potential biases in the results caused by sample selection and endogeneity are handled properly second to pay more attention to heterogeneous outcomes third to use continuous indicators of depth and breadth of links allowing for non linear relationships and fourth to extend evidence for developing countries and service industries

selection on observed and unobserved variables assessing the effectiveness of catholic schools in this paper we measure the effect of catholic high school attendance on educational attainment and test scores because we do not have a good instrumental variable for catholic school attendance we develop new estimation methods based on the idea that the amount of selection on the observed explanatory variables in a model provides a guide to the amount of selection on the unobservables we also propose an informal way to assess selectivity bias based on measuring the ratio of selection on unobservables to selection on observables that would be required if one is to attribute the entire effect of catholic school attendance to selection bias we use our methods to estimate the effect of attending a catholic high school on a variety of outcomes our main conclusion is that catholic high schools substantially increase the probability of graduating from high school and more tentatively attending college we find little evidence of an effect on test scores

is bitcoin a commodity on price jumps demand shocks and certainty of supply abstract this paper discusses how similar bitcoin is to a commodity the application of a number of both linear and non linear garch models indicates that the role of extreme price movements is particularly pronounced garch models with student t innovations as well as combined jump garch models are among the models with the best fit the role of large movements is found to be stronger in the bitcoin market than in the markets for crude oil and gold as bitcoin shares with these exhaustible resource commodities characteristics such as the fixed supply the analysis of bitcoin prices can generally learn from the analysis of exhaustible resource commodities however whereas the short run supply of gold and oil are uncertain there are no uncertainties on the bitcoin supply side thus the observed movements of bitcoin prices can be interpreted as results of bitcoin demand shocks

the inefficiency of bitcoin bitcoin has received much attention in the media and by investors in recent years although there remains scepticism and a lack of understanding of this cryptocurrency we add to the literature on bitcoin by studying the market efficiency of bitcoin through a battery of robust tests evidence reveals that returns are significantly inefficient over our full sample but when we split our sample into two subsample periods we find that some tests indicate that bitcoin is efficient in the latter period therefore we conclude that bitcoin in an inefficient market but may be in the process of moving towards an efficient market

in defence of the linear model an essay this essay discusses the strength and weaknesses of the so called linear model lm of innovation it is a reaction to the habit of criticising it as over simplistic mechanistic or simply blatantly wrong we argue that while some criticisms are of course well grounded many others are instead based on loose interpretations and unwarranted assumptions in order to separate the wheat from the chaff this essay first presents a comprehensive description of the linear model and differentiates it from the caricature many refer to second we discuss the main criticisms put forward and argue that many of them are not at all destructive but can be easily accepted within a refined version of the lm third we discuss the policy implications often derived or said to derive from the lm to argue that the lm itself is distinctively policy neutral other assumptions have to be added to justify alternative policy implications

ownership and firm innovation in a transition economy evidence from china we examine innovation performance of firms in a transition economy from an ownership perspective we focus specifically on the relationship between ownership structures and firm innovation performance drawing on data from 548 chinese firms we find volume of patent registration to be most strongly influenced by foreign ownership in the firm along with firm affiliation within a business group the influence of state and institutional ownership on innovation performance is positive but lagged contrary to expectations insider ownership leads to lower innovation performance and concentrated ownership has no significant impact our study has two principal contributions firstly we utilize a comprehensive treatment of ownership characteristics overcoming weakness in previous studies that have used a more narrow focus on ownership type secondly we contribute to understanding of how firms in transition economies build indigenous capabilities for innovation by drawing attention to the interplay of foreign and domestic control of agents innovation

price discovery of cryptocurrencies bitcoin and beyond abstract academic research on cryptocurrencies is almost exclusively directed towards bitcoin we extend existing literature by performing various tests on efficiency of several cryptocurrencies and additionally link efficiency to measures of liquidity cryptocurrencies become less predictable inefficient as liquidity increases

globalisation of knowledge production and regional innovation policy supporting specialized hubs in the bangalore software industry abstract this paper is concerned with the changing role of regional innovation systems and regional policies in supporting the transition of indigenous firms in developing countries from competing on low costs towards becoming knowledge providers in global value chains special attention is paid to policies supporting the emergence and development of the regional innovation system in this transition process regional innovation systems in developing countries have very recently started to be conceptualised as specialized hubs in global innovation and production networks asheim b coenen l vang lauridsen j 2007 face to face buzz and knowledge bases socio spatial implications for learning innovation and innovation policy environment and planning c government and policy 25 5 655 670 chaminade c vang j 2006a innovation policy for small and medium size smes in asia an innovation systems perspective in yeung h ed handbook of research on asian business edward elgar cheltenham maggi c 2007 the salmon farming and processing cluster in southern chile in pietrobello c rabellotti r eds upgrading and governance in clusters and value chains in latin america harvard university press a specialized hub refers to a node in a global value chain that mainly undertakes one or a few of the activities required for the production and development of a given good or service or serves a particular segment of the global market in global value chains firms in developing countries have traditionally been responsible for the lowest added value activities however a few emerging regional innovation systems in developing countries are beginning to challenge this scenario by rapidly upgrading in the value chain there is however still only a poorly developed understanding of how the system of innovation emerges and evolves to support this transition process and what the role of regional innovation policy is in building the regional conditions that support indigenous small and medium size enterprises smes in this transition process this paper aims at reducing this omission by analyzing the co evolution of the strategies of indigenous smes and the regional innovation system of bangalore india

a survey of the literature on human capital intensive firms the aim of this paper is to provide an exhaustive survey of the academic research dedicated to the study of human capital intensive firms hcifs we use a bibliometric analysis based on the three widely used databases econlit science direct and wiley over the period 1992 2015 we are adapting a methodology developed in previous works to our specific object of study and we generate a bottom up clustering on keywords titles and abstracts our examination of the data sheds a light on five main clusters of works that respectively focus on 1 critical human resource management 2 intellectual capital assessment 3 funding risk and innovation 4 high skilled employees supporting economic development and 5 internal and external valuable social networks in a critical appraisal of our results we stress that the bibliometric analysis remains silent on how the different clusters are linked with each other based on our own appreciation of the hcifs literature we propose a further step in the identification of a central question linking up these clusters a transversal review of the five clusters reveals that hcifs appear as a network of specialized agents whose complementary human resources are decisive for the value creation process

firm technological trajectory as a driver of eco innovation in young small and medium sized enterprises abstract few studies have focused on green innovation in young small and medium sized enterprises instead research tends to focus on large companies with formal research and development departments studying the influence of the firm s current technological strategy as well as the regulatory framework as a key driver of eco innovation this paper proposes that the combination of a firm s technological trajectory and its current research and development strategy are key determinants of eco innovation the authors investigate these relationships with panel data on 212 young firms in spain analysing their innovation strategy and behaviour during their first 10 years of activity the results show that the firms cluster into four technological trajectories but only market oriented innovators engage significantly more in eco innovation these firms are characterized by a high use of formal appropriability mechanisms market opportunity recognition arising from cooperation and high knowledge cumulativeness this paper sheds light on whether and the extent to which a firm s technological trajectory is a driver of eco innovation it confirms that firms that search for opportunities and have a continuous collaboration with market players are more prone to develop eco innovations additionally it shows that path dependence occurs in the development of eco innovations in that a highly developed innovation capacity leads to additional green innovation in the future the findings indicate that young small firms need to develop innovation capabilities that also enable them to adopt advanced technology before striving to become greener the paper concludes that policies designed to stimulate cooperative networking with other market players an upgrading of technological capabilities and the adoption of new technologies are all desirable because they contribute to improving the environmental impact of firms innovations

growth empirics a panel data approach a comment this paper comments on recent developments in the literature on the econometric analysis of international growth and convergence it notes that panel estimates of the neoclassical model accommodating level effects for individual countries through heterogeneous intercepts deal with some of the econometric difficulties arising in some of the earlier cross sectional studies but it notes that in dynamic panels heterogeneity in growth effects and in speeds of convergence renders this estimator inconsistent also the pervasiveness of such heterogeneity is demonstrated in three samples of countries and the effects of incorrectly imposing homogeneity on estimated parameters are illustrated and discussed

does twitter predict bitcoin this paper adds to the growing literature of bitcoin by examining the link between investor attention and bitcoin returns trading volume and realized volatility unlike previous studies we employ the number of tweets from twitter as a measure of attention rather than google trends as we argue this is a better measure of attention from more informed investors we find that the number of tweets is a significant driver of next day trading volume and realized volatility which is supported by linear and nonlinear granger causality tests

the timing and persistence of fiscal policy impacts on growth evidence from oecd countries the literatures testing for aggregate short run or long run growth impacts of fiscal policy use quite different methodologies the former generally focuses on temporary fiscal shocks the latter typically have no short run dynamics or assume homogeneity we use regression methods that treat heterogeneous short run dynamics explicitly within a long run model results suggest that previously estimated long run growth effects of fiscal policy are typically achieved quickly consistent with results from short run models in principle these short run effects persist in practice regular fiscal policy changes in oecd countries mean that persistent increases or decreases in growth rates are rare the recent global recession has brought renewed interest in the question can fiscal policy affect the growth rate of output if so are these effects temporary affecting only output levels over the longer run or permanent so that output growth rates are persistently higher perhaps surprisingly the literatures looking for growth impacts of fiscal policy over the short run say up to five years and over the longer run of 10 years or more have tended to be quite distinct and followed quite different methodologies this article considers how far the results from these two literatures are consistent to do so we apply the heterogeneous panel econometric methods mean group and pooled mean group proposed by pesaran and smith 1995 pesaran 1997 and pesaran et al 1999 to an annual panel dataset for oecd countries these methods allow both long run equilibrium relationships and short run dynamic adjustments around those equilibria to be investigated simultaneously in brief our results support the conclusion that changes in fiscal structure that is between different types of tax

on the inefficiency of bitcoin abstract urquhart 2016 investigated the market efficiency of bitcoin by means of five different tests on bitcoin returns it was concluded that the bitcoin returns do not satisfy the efficient market hypothesis we show here that a simple power transformation of the bitcoin returns do satisfy the hypothesis through the use of eight different tests the transformation used does not lead to any loss of information

measuring human capital and its effects on wage growth ever since mincer years of labour market experience were used to approximate individual s general human capital while years of seniority were used to approximate job specific human capital this specification is restrictive because it assumes that starting wages at a new job depend only on job market experience in this paper i investigate the effects of human capital on wage growth by using a more flexible specification of the wage equation which allows for a rich set of information on past employment spells to affect the starting wages in addition i endogenize the labour mobility decision in order to illuminate the effects of human capital accumulation patterns on wage growth i compare counterfactual career paths for representative individuals copyright 2010 blackwell publishing ltd

fiscal policy long run growth and welfare in a stock flow model of public goods we introduce public capital and public services as inputs in an endogenous growth model we show that the growth rate depends on the apportionment of tax revenues between the accumulation of public capital and the provision of public services when public spending is financed by proportional income taxes the growth rate the level of public spending as a proportion of gdp the level of investment in public capital as a proportion of total public spending and the level of private investment as a proportion of total private spending all are lower in the equilibrium outcome than in the optimal outcome jel classification e62 o40 politique fiscale croissance a long terme et bien etre dans un modele stock flow de biens publics les auteurs introduisent du capital public et des services publics comme intrants dans un modele de croissance endogene on montre que le taux de croissance depend de l allocation des revenus de la fiscalite entre l accumulation de capital public et la fourniture de services publics quand les depenses publiques sont financees par un impot proportionnel sur le revenu le taux de croissance le niveau de depenses publiques en pourcentage du pib le niveau d investissement en capital public et le niveau d investissement prive en proportion de la depense totale privee sont tous moins eleves au niveau d equilibre que ce qui serait le resultat optimal

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

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

evaluating the efficiency and equity of federal fiscal equalization abstract theoretically federal transfers that make household location decisions efficient should ignore local cost differences subsidize positive externalities and offset differences in federal tax payments and local taxes levied on non residents but not local tax revenues from residents transfers that redistribute resources equitably across regions will likely target areas with individuals of low earnings potential or low real incomes applying these criteria empirically canadian equalization policy appears neither efficient nor equitable but exacerbates pre existing inefficiencies and underfunds minorities locational inefficiencies cost canada 0 41 of income annually and cause over funded provinces to have populations of 30 beyond their efficient long run levels

cost and income based measures of human capital human capital is increasingly believed to play an important role in the growth process however adequately measuring its stock remains controversial in this paper three general approaches to measurement are identified cost based income based and educational stock based this survey focuses on the first two approaches and provides a critical review of the theories and their applications to data from a range of countries particular emphasis is placed upon the work of jorgenson and fraumeni 1989 1992 and some new results for new zealand based upon their approach are also presented

human capital measurement theory and practice in early 2010 the us economy sits in its most precarious position since the great depression of the 1930s at its height in 1933 25 of all workers and 37 of all non farm workers were completely out of work the unemployment rate in the usa is now over 9 5 1 as figure 1 indicates when the us economy spirals into severe recession unemployment cascades up as well periods of recession coincide with significant rise in unemployment and the two forces feed on each other taxing economic systems when consumer spending declines and capital stock markets endure significant loss unemployment spirals upward earned income tax revenue declines government expenditure on benefits for the unemployed increase consumer spending declines further and sales tax revenue declines housing values decline in a recession which causes property tax revenue to decline which causes a shortfall in municipal tax revenue so city budgets do not balance so more unemployment occurs now in the public sector the us and the world economy in general are still in the throes of such cataclysmic events even while this is written in the summer of 2009 europe s economy continues in a similarly dire situation with overall unemployment at 9 5 for the european union as of may 2009 2 interestingly australia unemployment hovers in the 5 8 rate range 3 the crash of the us economy has reverberated throughout the world and adversely impacted virtually every other economic system on the globe this sad fact is well known and undisputed by economists and social scientists throughout the world the us congress sits as this is being written in the summer of 2009 and debates an almost 1 trillion dollar healthcare package to assist in part in bringing the us economy out of crisis on february 17th of 2009 us president obama signed into law an 800 billion plus stimulus package significant debate in the usa continues as to whether the immense government spending and attendant increase in debt has done any good britain germany and other world powers are undergoing similar investments and debates hundreds of millions of these dollars are earmarked for projects to increase employment and increase the human capital hc of the world labour force on programmes such as educational loans and subsidies

transaction cost economics in real time this paper attempts to place the theq of the boundaries of thejirm within the context of the passage of time more precisely it resurrects and places in a modem frame some of the insights of the chsical and marshallian theories of organization the modem reinterpretation of those theories centers around the capabilities view of the jirm taken together with governance costs the capabilities ofjirm and market determine the boundaries of the jirm in the short run ovw time capabilities change as firms and markets learn which implies a kind of information or knowledge cost the cost of trandewing the firm s capability to the market w vice versa these dynamic governance costs are the costs of persuading negotiating and coordinating with and teaching others they arise in the face of change notably txchnological and organizational innovation in fit they are the costs of not having the capabilities you need when you need them dynamic transaction costs provide an explanation for vertical integration that is arguably more general than those dominant in the literature in the face of uncertainty and divwgent views ofthe future common ownership of multiple stages of production is a supwior institutional arrangement for coordinating systemic change asset specrfity is neither necessary nor suffient for this to be true dynamic governance costs may also affit internal organization it may sometimes be costly in 3 terms of persuasion negotiation and teaching to create within the firm capabilities readily available on the market indeed in cases in which systemic coordination is not 4 the issue the market may turn out to be the superior institution of coordination in e 2 genwal the capabilities view of the jirm suggests that we look atfim2 and market as alternative and sometimes overlapping institutions of learning 1 transaction costs in the long rzln and the short 9 x classical and neoclassical perspectives

some determinants of cost distributions in the process of technological innovation abstract industrial research and development r d is a set of activities within the broader set of decisions and activities the process of technological innovation ti it is technology transfer commercialization of the innovation that leads to technology diffusion that permits production and employment expansion and hence economic growth an important goal of industrial policy firms managements and government policy makers should recognize the close relationships among the phases of ti and direct their policy planning budgeting and control decisions to the complete process many policies currently focus their attention to only one or a few points such as r d in this study we conducted a detailed cost analysis of a limited number of innovation projects and studied the distributions of ti cost over the process phases we find that almost half of ti costs are devoted to r d which implies that government support of this phase is important different cost patterns emerge when we classify innovations by industrial sectors firms sizes and project complexity complex innovations require larger and more variable risky r d budgets smaller firms need more assistance in technology transfer these are only a few important policy implications this study emphasizes the importance of post r d phases and concludes that differential industrial policy may be required for technological innovations

specifying human capital a review of the measures of the stock of human capital used in empiricalgrowth research including adult literacy rates school enrollmentratios and average years of schooling of the working age population reveals that human capital is mostly poorly proxied the simple use ofthe most common proxy average years of schooling misspecifies therelationship between education and the stock of human capital based onhuman capital theory the specification of human capital is extended toallow for decreasing returns to education and for differences in thequality of a year of education the different specifications give riseto hugely differing measures of the stock of human capital acrosscountries and development accounting results show that misspecifiedhuman capital measures can lead to severe underestimation of thedevelopment effect of human capital

the roles of science in technological innovation abstract one of the central issues in science policy during the past decade has been the extent to which the national levels of expenditure on scientific education and research influence the standard of living this paper provides empirical evidence to show that the pay off from this investment in science is more complex and indirect than previously supposed

organizational change skill formation human capital measurement evidence from italian manufacturing firms basing on a job competition approach in this paper we provide a labour demand oriented measure of human capital as defined by the amount of specific skills a firm generates through work based training wbt activities by merging three rich firm level datasets we estimate the impact of a set of variables that are supposed to affect both the propensity to invest in wbt and the intensity of training within the italian manufacturing industry over the period 2001 2005 the estimates show that the effects of innovation on wbt is higher when the introduction of new technologies is supported by organizational innovations when looking at the nature of wbt we investigate the different determinants of the firms propensity to provide both in house and outside training finally we estimate training intensity in terms respectively of the number of training activities provided private and total training costs and the share of trainees

cryptocurrencies and momentum abstract retrieving a set of 143 cryptocurrencies for a sample spanning 2014 2018 we investigate the popular momentum strategy implemented in the cryptocurrency market contrary to earlier studies our findings do not indicate any evidence of significant momentum payoffs supporting the view that the cryptocurrency market is far more efficient than suggested in earlier studies

analyzing literature based innovation output indicators the italian experience abstract this paper presents the results of a study on the product innovations introduced in the italian market in 1989 and reported in a selected number of trade journals the analysis of data collected by means of this literature based counting procedure confirms that r d oriented industries and large firms do not in italy have a marked competitive advantage in innovation the country appears to be instead characterized by a significant presence of consumer goods industries and small firms in innovation our data indicate a statistically significant association between trade competitiveness and strength in product innovation and show the comparatively higher capacity for product innovation of some of the industries in which italy achieves a positive performance in international trade moreover the presence of spillovers at the regional level from both private and public r d expenditures proves to be positively correlated with the development of product innovations finally small firms with fewer than 50 employees appear to be more innovative than is usually believed to be the case

the role of knowledge in r d efficiency past research has recognized that both demand and capability influence the allocation of r d resources scholars have had an easier time getting a grip on demand than on capability while it has been recognized that knowledge is an important part of capability to date formalization of knowledge and its role in r d activity has been unsatisfactory this paper models the role of knowledge in r d various sources of such knowledge are considered the model throws a different light on analyses that employ a knowledge capital stock and also illuminates the dual private and public nature of technological knowledge
