environmental regulation and u s economic growth in this article we quantify the costs of pollution controls by reporting the results of simulations of the growth of the u s economy with and without regulation for this purpose we have constructed a detailed model of the economy that includes the determinants of long term growth we have also analyzed the interaction between industries in order to capture the full repercussions of environmental regulations however we have not attempted to assess the benefits resulting from a cleaner environment we find that pollution abatement has emerged as a major claimant on the resources of the u s economy the cost of emission controls is more than 10 of the total cost of government purchases of goods and services

cooperative and noncooperative r d in duopoly with spillovers contrary to the usual assumption made in most oligopoly models relations among firms are seldom of a wholly cooperative or noncooperative type in many situations they compete in some fields while they cooperate in others an important example is the case of cooperative research efforts bringing fierce competitors together two types of agreement are observed first r d cooperation can take place at the so called precompetitive stage companies share basic information and efforts in the r d stage but remain rivals in the market place 1 a second type of agreement involves an extended collusion between partners creating common policies at the product level the usual justifications of this extension are the difficulties of protecting intellectual property the idea is then to allow partners who have achieved inventions together to also control together the processes and products which embody the results of their collaboration in order to recuperate jointly their r d investments 2 what could be expected from these types of agreement is a reduction in r d expenditures because of less wasteful duplication and a reduction of total production because of more reprinted from the american economic review 78 5 1133 1137 1988 center for operations research econometrics 1348 louvain la neuve belgium we are grateful to jean

measuring the pricing error of the arbitrage pricing theory this article provides an exact bayesian frame work for analyzing the arbitrage pricing the ory apt based on the gibbs sampler we show how to obtain the exact posterior distributions for functions of interest in the factor model in particular we propose a measure of the apt pricing deviations and obtain its exact posterior distribution using monthly portfolio returns grouped by industry and market capitalization we find that there is little improvement in reduc ing the pricing errors by including more factors beyond the first one as an important extension of the asset pricing model of sharpe 1964 and lintner 196 5 ross 1976 1977 derived the arbitrage pricing theory apt which addresses a fundamental problem in finance to char acterize the expected return on a security the apt implies that the expected return is approximately a

technical change external economies and the porter hypothesis abstract michael porter introduces the idea that environmental regulations may benefit affected firms this paper derives results consistent with porter s hypothesis by employing a general equilibrium framework with a large number of agents external economies of scale in production and discrete changes in technology the model shows that endogenous technical change makes porter s hypothesis feasible however a policy that produces results consistent with porter s hypothesis is not necessarily optimal

taxing variable cost environmental regulation as industrial policy abstract conventional wisdom has it that a country that enacts strict environmental regulations will place its firms at a competitive disadvantage this view has been challenged recently some commentators argue that stricter regulation will enhance domestic competitiveness strict regulations induce innovation we evaluate this argument in a strategic trade model in very special cases a strengthening of regulation may result in a shift of profits from foreign to domestic firms this is not a general result however environmental regulation should of course be imposed to control externalities but it is unlikely that it will serve to generate industrial advantage

nowcasting the real time informational content of macroeconomic data abstract a formal method is developed for evaluating the marginal impact that intra monthly data releases have on current quarter forecasts nowcasts of real gross domestic product gdp growth the method can track the real time flow of the type of information monitored by central banks because it can handle large data sets with staggered data release dates each time new data are released the nowcasts are updated on the basis of progressively larger data sets that reflecting the unsynchronized data release dates have a jagged edge across the most recent months

social cost of environmental quality regulations a general equilibrium analysis the use of cost benefit analysis by federal regulatory agencies has expanded greatly in scope and sophistication unfortunately agencies continue to employ private cost rather than social cost to evaluate environmental quality regulations furthermore general equilibrium impacts and intertemporal effects of regulations are typically not included in the evaluation in this paper we estimate the social cost of environmental quality regulations mandated by the clean air and clean water acts we construct an econometric general equilibrium model of the united states to demonstrate that social cost estimates diverge sharply from private cost estimates we also demonstrate that general equilibrium impacts are significant and pervasive and that intertemporal effects of the regulations heretofore ignored are significant

dynamic hierarchical factor models this paper uses multilevel factor models to characterize within and between block variations as well as idiosyncratic noise in large dynamic panels block level shocks are distinguished from genuinely common shocks and the estimated block level factors are easy to interpret the framework achieves dimension reduction and yet explicitly allows for heterogeneity between blocks the model is estimated using an mcmc algorithm that takes into account the hierarchical structure of the factors the importance of block level variations is illustrated in a four level model estimated on a panel of 445 series related to different categories of real activity in the united states

macroeconomic factors and microlevel bank behavior we analyze the link between banks and the macroeconomy using a model that extends a macroeconomic var for the u s with a set of factors summarizing conditions in about 1 500 commercial banks we investigate how macroeconomic shocks are transmitted to individual banks and obtain the following main findings backward looking risk of a representative bank declines and bank lending increases following expansionary shocks forward looking risk increases following an expansionary monetary policy shock there is however substantial heterogeneity in the transmission of macroeconomic shocks which is due to bank size capitalization liquidity risk and the exposure to real estate and consumer loans

tightening environmental standards the benefit cost or the no cost paradigm ms ff ichael porter and claas van der linde have written a paper that is interesting and to us at least somewhat astonishing it is a defense of environmental regulation indeed an invitation to more stringent regulation that makes essentially no reference to the social benefits of such regulation this approach contrasts starkly with the methods that economists and other policy analysts have traditionally used when assessing environmental or other regulatory programs the traditional approach consists of comparing the beneficial effects of regulation with the costs that must be borne to secure these benefits for environmental regulation the social benefits include the reductions in morbidity or premature mortality that can accompany cleaner air the enhanced recreational opportunities that can result from water quality improvements the increased land values that might attend the cleanup of a hazardous waste site the enhanced vitality of aquatic ecosystems that might follow reductions in agricultural pesticide use or any of the other potentially significant benefits associated with tighter standards from this benefit cost approach emerges the standard tradeoff discussed in virtually every economics textbook porter and van der linde deny the validity of this approach to the analysis of environmental regulation claiming it to be an artifact of what they see as a static mindset in their view economists have failed to appreciate the capacity of

toward a new conception of the environment competitiveness relationship accepting a fixed trade off between environmental regulation and competitiveness unnecessarily raises costs and slows down environmental progress studies finding high environmental compliance costs have traditionally focused on static cost impacts ignoring any offsetting productivity benefits from innovation they typically overestimated compliance costs neglected innovation offsets and disregarded the affected industry s initial competitiveness rather than simply adding to cost properly crafted environmental standards can trigger innovation offsets allowing companies to improve their resource productivity shifting the debate from pollution control to pollution prevention was a step forward it is now necessary to make the next step and focus on resource productivity

a resource based perspective on corporate environmental performance and profitability drawing on the resource based view of the firm we posited that environmental performance and economic performance are positively linked and that industry growth moderates the relationship with the returns to environmental performance higher in high growth industries we tested these hypotheses with an analysis of 243 finns over two years using independently developed environmental ratings results indicate that it pays to be green and that this relationship strengthens with industry growth we conclude by highlighting the study s academic and managerial implications making special reference to the social issues in management literature

bayesian dynamic factor models and portfolio allocation we discuss the development of dynamic factor models for multivariate financial time series and the incorporation of stochastic volatility components for latent factor processes bayesian inference and computation is developed and explored in a study of the dynamic factor structure of daily spot exchange rates for a selection of international currencies the models are direct generalizations of univariate stochastic volatility models and represent specific varieties of models recently discussed in the growing multivariate stochastic volatility literature we discuss model fitting based on retrospective data and sequential analysis for forward filtering and short term forecasting analyses are compared with results from the much simpler method of dynamic variance matrix discounting that for over a decade has been a standard approach in applied financial econometrics we study these models in analysis forecasting and sequential portfolio allocation for a selected set of international exchange rate retur

exploring links between innovation and diffusion adoption of nox control technologies at us coal fired power plants while many studies have looked at innovation and adoption of technologies separately the two processes are linked advances and expected advances in a single technology should affect both its adoption rate and the adoption of alternative technologies this paper combines plant level data on us coal fired electric power plants with patent data pertaining to nox pollution control techniques to study this link as in other studies of environmental technologies the effect of other explanatory variables is dominated by the effect of environmental regulations demonstrating that the mere presence of environmental technologies is not enough to encourage its usage nonetheless i do find that technological advances are important for the adoption of existing combustion modification technologies however these advances are less important for the adoption of newer post combustion control techniques which are adopted only when needed to comply with the strictest emission limits

nonparametric measurement of productive efficiency in the presence of regulation abstract during the late 1970s and 1980s volatility in the demand for natural gas in the united states created havoc in the industry s transmission sector managers of firms were presented with the task of improving productive efficiency in an uncertain and regulated industry we measure the relative performance of 20 pipelines using data envelopment analysis dea to produce a regulation constrained minimum cost frontier with the results we construct a fisher productivity index fpi results show that despite productive efficiency decline for most years most firms experienced improvement in technical efficiency and technical progress in most years most of the productive efficiency decline was due to scale diseconomies

international business cycles world region and country specific factors the paper investigates the common dynamic properties of business cycle fluctuations across countries regions and the world we employ a bayesian dynamic latent factor model to estimate common components in macroeconomic aggregates output consumption and investment in a 60 country sample covering seven regions of the world the results indicate that a common world factor is an important source of volatility for aggregates in most countries providing evidence for a world business cycle we find that region specific factors play only a minor role in explaining fluctuations in economic activity we also document similarities and differences across regions countries and aggregates jel f41 e32 c11 c32

productivity growth and environmental regulation in mexican and u s food manufacturing many argued during the nafta debate that trade liberalization would favor mexican over u s food processors especially because of lax environmental laws south of the border we find through an examination of profit functions that productivity growth in mexico has outstripped that in the united states suggesting free trade indeed will benefit mexican suppliers u s pollution regulations have had no impact on the profitability or productivity of u s food manufacturing in contrast mexico s swiftly rising environmental standards have enhanced food processors productivity growth corroborating the porter hypothesis pollution law therefore has favored mexican over u s food processing but for reasons few had anticipated

epa s voluntary 33 50 program impact on toxic releases and economic performance of firms abstract this paper examines the motivations for participation in the voluntary 33 50 program and the program s impact on the toxic releases and economic performance of firms in the u s chemical industry it demonstrates that the benefits due to public recognition and the potentially avoided costs of liabilities and compliance under mandatory environmental regulations provide strong incentives for participation after controlling for sample selection bias and the impact of other firm specific characteristics this paper shows that program participation led to a statistically significant decline in toxic releases over the period 1991 93 the program also had a statistically significant negative impact on the current return on investment of firms but its impact on the expected long run profitability of firms was positive and statistically significant

a theoretical foundation of the porter hypothesis abstract this letter shows that by reducing agency costs an environmental regulation may enhance pollution reducing innovation while at the same time increasing firms private benefit

co movements in commodity prices global sectoral and commodity specific factors this paper characterizes the co movements in commodity prices with a dynamic latent factor model that decomposes commodity returns into global sectoral and idiosyncratic components the results indicate that global and sectoral factors are important sources of co movements in commodity returns a sub sample analysis further reveals that the global factor increases significantly in importance since 2004 which indicates an increasing integration among commodity markets

does the porter hypothesis explain expected future financial performance the effect of clean water regulation on chemical manufacturing firms previous research provides opposing theoretical arguments regarding the effect of environmental regulation on financial performance as one important argument the porter hypothesis claims that tighter regulation improves financial performance this study provides empirical evidence on this debated effect in particular we employ panel data analysis to examine the effect of clean water act regulation as measured by permitted wastewater discharge limits on expected future financial performance as measured by tobin s q for publicly owned firms in the chemical manufacturing industries we find that tighter permitted discharge limits lower tobin s q i e more stringent clean water act regulation undermines expected future financial performance by decomposing tobin s q into its constituent components market value and replacement costs and estimating each component separately we find that tighter permitted discharge limits lower both components with a larger impact on market value which implies that investors revise their expectations of the discounted present value of future profits in response to changes in clean water act regulation

the cost of regulation osha epa and the productivity slowdown the slowdown in productivity growth in the u s economy during the 1970 s has been a matter of great concern to policymakers associated as it is with inflation unemployment and declining real wage growth this paper examines the impact on productivity growth of government regulation specifically worker health and safety regulation by the occupational safety and health administration osha and environmental regulation by the environmental protection agency epa looking at data for 450 manufacturing industries between 1958 and 1978 the study finds a large negative relationship between such regulation and productivity growth using these results about 30 percent of the decline in productivity growth in manufacturing during the 1970 s may be attributed to such regulation several previous studies have looked at the contribution of regulation to the productivity slowdown many of these have inferred that the contribution must be small on the basis of the relatively small amount spent on complying with such regulations edward denison 1979 estimates that only about 16 percent of the productivity slowdown in the 1972 75 period was due to regulation 35 percentage points out of a slowdown of 2 17 percentage points paul portney 1981 notes that little of gnp is spent on pollution control under 2 percent concluding that therefore pollution regulations could have little effect on productivity growth norsworthy et al 1979 also find a small impact of pollution abatement capital expenditures on productivity growth studies based on econometric estimation of the regulation productivity relationship have found a wide range of results gregory christainsen and robert haveman 1981 find regulation reduced labor productivity growth by 27 percentage points using time series data and measures of total federal regulation robert crandall 1981 finds a strong relationship between pollution abatement capital and productivity growth but this relationship disappears when a measure of energy intensity is included robin siegel 1979 observes a significant contribution 5 percentage points from pollution control expenditures to the productivity slowdown for 1965 73 but not for later years finally frank gollop and mark roberts 1983 examine data for a set of electric utilities and find that regulation of emissions had a large impact on total factor productivity growth lowering it for regulated firms by 59 percentage points many other factors might help to explain the productivity slowdown including the rise in energy prices the long and severe recession and declines in research and development expenditures there have been a variety of studies examining the contributions of each factor to the slowdown they generally conclude that many factors contributed to the slowdown but that a sizable fraction of the slowdown remains unexplained by the estimated contributions of all the factors considered

retrieving and transferring embodied data implications for the management of interdependence within organizations this research helps to link theories of sticky information with organizational design and governance it suggests that information embodied in process material can allow downstream tasks to uncover information about upstream tasks it shows that downstream operators can use this information to negotiate interdependence problems with upstream operators data presented in this article begin to uncover when such information retrieval and exchange occurs and how managers can encourage it finally the article discusses implications for theories of operational design and governance

euro area business cycles in turbulent times convergence or decoupling we study the business cycle properties of the four largest european economies in the wake of the recent recession episodes the analysis is based on the factors estimated from a multi country and multi sector data rich environment we measure alikeness of business cycles by studying the synchronization of up and down phases the convergence properties of country fluctuations towards the euro area ea cycles and the contribution of the ea factor to national gdp volatilities while the economic fluctuations of the four ea member states were similar before the global financial turmoil we gather compelling evidence of an asymmetric behaviour of spanish fluctuations relative to the ea one

a multilevel factor model identification asymptotic theory and applications this paper studies a multilevel factor model with global and country factors the global factors affect all individuals while the country factors affect only those within each specific country a sequential procedure to identify the global and country factors separately is proposed in the initial step the global factors are estimated by canonical correlation analysis using this initial estimator the principal component estimators pces of the global and country factors are constructed it is shown that the pces estimate the spaces of the global and country factors consistently and are normally distributed in the limit several information criteria that can estimate the numbers of the country factors are proposed the number of the global factors is assumed to be known extensive simulation results demonstrate that the sequential procedure and the information criteria work well in finite samples the method of this paper is applied to 25 oecd countries to identify international business cycle it is reported that the method extracts a global factor reasonably well

on the importance of sectoral and regional shocks for price setting summary we use novel disaggregate sectoral regional euro area data to investigate the sources of price changes introducing a new method to extract factors from overlapping data blocks that allows for estimation of aggregate sectoral country specific and regional components of price changes our sectoral component explains much less variation in disaggregate inflation rates and exhibits much less volatility and more persistence than previous findings for the us indicate country and region specific factors play an important role emphasizing heterogeneity of inflation dynamics along both sectoral and geographical dimensions our results are incompatible with basic sticky information or calvo type price setting models but require multi sector multi country models copyright 2015 john wiley sons ltd

analyzing business cycle asymmetries in a multi level factor model abstract we study the business cycle in the us over 1959 2011 using a large dimensional multi level factor model we find notable asymmetries over the business cycle but the bulk of common dynamics is stable over time the comovement among variables is larger in recessions compared to expansions the recession factor is highly correlated with monetary and financial variables whereas expansion and symmetric factors are mainly related to real activity variables
