co2 emissions energy consumption and economic growth in china a panel data analysis this paper examines the causal relationships between carbon dioxide emissions energy consumption and real economic output using panel cointegration and panel vector error correction modeling techniques based on the panel data for 28 provinces in china over the period 1995 2007 our empirical results show that co2 emissions energy consumption and economic growth have appeared to be cointegrated moreover there exists bidirectional causality between co2 emissions and energy consumption and also between energy consumption and economic growth it has also been found that energy consumption and economic growth are the long run causes for co2 emissions and co2 emissions and economic growth are the long run causes for energy consumption the results indicate that china s co2 emissions will not decrease in a long period of time and reducing co2 emissions may handicap china s economic growth to some degree some policy implications of the empirical results have finally been proposed

effects of energy price rise on investment firm level evidence from indian manufacturing sector this paper analyses the effects of the rising prices of energy products on the investment of a large panel of manufacturing firms in india during 1993 2013 the prime motivation behind this study is the absence of an empirical study into this research issue exclusively on indian economy the empirical results obtained by estimating an error correction model ecm using generalized method of moments gmm show that energy price rise has negative effect on the investment of firms in the manufacturing sector the negative effect is transmitted to the firm s investment through both demand side and supply side factors the transmission also depends upon factors such as the energy intensity of production the results also show that the sales growth investment relationship becomes weak in the face of the rising prices of the energy which could be due to the cautious approach to investment adopted by the firms therefore it calls for the attention of the policy makers to evolve a comprehensive energy policy to ensure continuous supply of energy at affordable prices to the manufacturers

farmers investment behavior an empirical assessment of two specifications of expectations the capital investment decision is modeled and two different assumptions about expectations are compared and tested using panel data for dutch dairy farms the utilization of panel data allowed to account for the possibility that the intercept in the function for capital varies over the farms the models are estimated using the generalized method of moments gmm for dynamic panel data the model based on static expectations fits the data well the results obtained from the rational expectations model are not consistent with the theory

intertemporal production and intertemporal substitution in output supply and input demand abstractthis article presents an intertemporal model of production with multiple inputs to investigate substitution opportunities facing firms over time the firm s intertemporal profit maximization problem is characterized with the familiar cost function and various intertemporal substitution elasticities are delineated for output supply and input demand the absence of intertemporal substitution in production can imply production smoothing and allowance for intertemporal substitution in labour demand reinforces the prediction of the real business cycle model for aggregate us manufacturing we find substantial substitution in output supply and labour demand over time due to intertemporal changes in output price and wage rates

estimation of scale economies underlying growth and productivity the empirical implications of data aggregation estimation of scale economies underlying growth and productivity patterns is typically based on aggregated data raising questions about the potential for aggregation biases this paper provides empirical evidence on the existence and patterns of such biases we use a cost based model to estimate short long run and internal external scale effects for u s manufacturing data at different aggregation levels our results suggest that aggregation biases in such a model are not substantive also internal scale economies seem more appropriately represented by the aggregate data whereas more disaggregated data appears preferable for estimation of external or spillover effects that occur between industries or sectors

outsourcing imports and labour demand this paper examines the effects of purchased services and imported intermediate materials on the labour demand for different skills in german manufacturing sectors we derive and estimate a factor demand system based on the generalised box cox cost function nesting both the normalised quadratic and the translog functional form we find that the impacts of output and capital growth are more important in explaining the demand for heterogeneous labour than substitution effects between labour and non labour inputs similarly the increasing use of both imported materials and purchased services is a consequence of output growth rather than input substitution

factor demand models with nonlinear short run fluctuations abstract this paper considers asymmetric costs of adjustment that propagate nonlinear shortrun fluctuations in stochastic factor demand systems the model endogenously generates asymmetric cyclical demand for capital and labour between peaks and troughs of the business cycle the empirical analysis of the model is based on quarterly time series data of the dutch manufacturing sector for the period 1971 i 1984 iv and annual time series data of the u k manufacturing sector for the period 1955 1986 i find important differences of adjustment speed of capital and labour inputs between expansionary and contractionary phases of the business cycle

exploring the determinants of emerging bioenergy market participation abstract individual biomass producers will play a strong role in the emergence of robust and sustainable bioenergy markets research on what drives their participation however is substantial but fragmented despite a recognition of producer heterogeneity there have also been few comparative analyses of drivers of bioenergy market participation across feedstock types producer groups and geographic regions through narrative review and network analysis the following review of the bioenergy market participation literature generates both an increased appreciation of how bioenergy market participation is assessed in existing research and how social network analysis may be further employed as a tool for literature review across 41 studies selected for qualitative review and a subset of 22 selected for quantitative review the analysis reaches two central conclusions the first pertains to the findings of the literature itself suggesting that a variety of non production objectives structural and social constraints and market related attributes influence bioenergy market participation decisions a second conclusion is that the assessment of these factors varies significantly across the literature for both user group and feedstock type further examination of the individual variables within these segments of the literature as well as of authorship patterns across them suggests that this variation may rise from differences in the subject matter itself and not from differing perspectives of the researchers undertaking the work should disparities in the literature be reflective of actual socio economic differences in their respective markets policies or programs targeted to individual feedstock types or user groups may be more effective in encouraging participation than uniform national policy initiatives

the determinants of aggregate energy use in west germany factor substitution technological change and trade this paper examines the determinants of production related energy use in west germany over the period 1976 1994 the approach is to estimate a system of share equations for energy capital low skilled labor high skilled labor and materials in the west german production sector taking account of biased technological change and increasing trade orientation while technological change is found to be energy saving increased openness is energy using i e tends to increase the energy share factor substitution biased technological change and trade contribute to the year to year volatility of energy intensity in the proportion 66 30 4 the results are robust across several specifications examined

scale economies and over capitalization in japanese electric utilities this paper presents empirical evidence on scale economies and overcapitalization in japanese electric utilities we employ the short run equilibrium model in which the variable cost function treats capital stock as a quasi fixed factor we specify the variable cost function as a translog form and estimate it using panel data of nine japanese electric utility firms during the period 1981 to 1985 our results show that eight of the nine firms experience scale economies in the short run but diseconomies in the long run and that seven firms significantly over capitalize as expected by the averch johnson effect

macroeconomic impact of the german energy transition and its distribution by sectors and regions abstract macroeconomic impacts such as changes in economic structures and employment are very important when evaluating the energy transition in societal terms we employ a macroeconomic model that accounts for regional economic and sectoral features the model results show how the overall positive net impacts of the energy transition in germany energy efficiency and renewable energies on economic growth and employment up to 2030 are distributed across sectors and regions the biggest relative increases in value added occur in construction real estate and electricity generation the biggest decrease is in mining of lignite significant effects mainly result from changes in the heat and transport sectors while the transition in the electricity sector entails smaller impacts the latter are however relevant to the regional distribution the model results suggest that especially northern and eastern german federal states will benefit economically from the energy transition because they offer attractive locations for investments at the same time these states are less affected by decreasing conventional energy generation moreover the impact of rising electricity prices is less negative here than in the other federal states because of their lower electricity intensity in production in summary the energy transition represents an opportunity for these regions to strengthen their economies

oil prices inflation and interest rates in a structural cointegrated var model for the g 7 countries sharp increases in the price of oil are generally seen as a major contributor to business cycle asymmetries moreover the very recent highs registered in the world oil market are causing concern about possible slowdowns in the economic performance of the most developed countries in this paper a structural cointegrated var model has been considered for the g 7 countries in order to study the direct effects of oil price shocks on output and prices and the reaction of monetary variables to external shocks our results can be summarized as follows i a stationary money demand as suggested by the classic theory of money can be identified for most countries ii according to the estimated coefficients of the structural part of the model for all countries except japan and u k the null hypothesis of an influence of oil prices on the inflation rate cannot be rejected inflation rate shocks are transmitted to the real economy by increasing interest rates iii impulse response analysis suggests for most countries the existence of an instantaneous temporary effect of oil price innovations on prices iv impulse response functions indicate different monetary policy reactions to inflationary and growth shocks v the simulation exercises directed to estimate the total impact of the 1990 oil price shock indicate that for some countries u s a significant part of the effects of the oil price shock is due to the monetary policy reaction function for other countries canada france and italy however the total impact is offset at least in part by an easing of monetary conditions

assessing energy price induced improvements in efficiency of capital in oecd manufacturing industries to assess how capital stocks adapt to energy price changes it is necessary to account for the impacts on different vintages of capital and to account separately for price induced and autonomous improvements in the energy efficiency of capital stock the results of econometric analysis for five manufacturing industries in 19 oecd countries between 1990 and 2005 indicate that higher energy prices resulted in smaller energy use due to both improved energy efficiency of capital stock and reduced demand for the energy input the investment response to energy prices varied considerably across manufacturing industries being more significant in energy intensive sectors the results of policy simulations indicate that a carbon tax can deliver significant reductions in energy consumption in the medium run with modest declines in energy using capital stock

public investment and industry incentives in life science research life science research has shifted rapidly from the public to the private sector raising questions about government s remaining role we shed light on the issue by employing a dynamic investment response model to examine the public s impact on industry life science research effort and success we find that government expenditures in both basic biological research and agricultural and medical science create substantial spillovers for private firms the spillovers are unfortunately partly nullified by government competition for scarce research inputs yet even after accounting for such competition public investment has been strongly complementary to private investment indeed opportunities created through public research are the principal source of growth in industry life sciences copyright 2007 oxford university press

energy use exports imports and gdp new evidence from the oecd countries this paper aims to investigate the relationship between energy use gdp energy use exports trade and energy use imports on aggregate level in the oecd countries while the energy use growth nexus is widely examined in the literature studies on the energy use trade nexus are very scarce thus this study also serves to fill this gap by presenting a new research on the oecd countries we employ the panel cointegration technique and use the granger representation theorem to examine the presence of long run relationship and the causality between pairs of variables to investigate the presence of causality several tests developed by canning and pedroni 2008 are used we find that the pairs of energy use gdp energy use exports and energy use imports are cointegrated and there is two way granger causality between each pairs we also estimate the long run elasticities by employing panel dynamic ordinary least squares the results suggest that the sign of long run elasticity is positive for all pairs particularly 1 increase in gdp export and import causes almost 0 32 0 21 and 0 16 increase in energy use respectively

an examination of the equilibrium specification and structure of production for canadian telecommunications multiple output models of canadian telecommunications production are estimated under different production equilibria a specification test is conducted between the short and long run equilibrium models and the long run equilibrium is rejected in order to capture the nature of the disequilibrium a dynamic cost of adjustment model is estimated for bell canada there are significant adjustment costs and it is estimated that for 1 00 of marginal capital costs the carrier must incur an additional cost of 0 30 to install the new capital into the production process

international and sectoral variation in industrial energy prices 1995 2015 energy price rises for industry are a major political concern access to cheap energy is often considered a key factor for the competitiveness of industry to enable international comparisons and to foster further empirical research on the impacts of energy price or tax differentials on a wide range of outcomes such as international trade and investment patterns we construct sector level energy prices for 12 industrial sectors in 48 countries for the period 1995 to 2015 our prices are constructed as weighted averages of fuel specific prices by fuel consumption we provide guidelines for the use of our energy price data which is made available for download as well as a set of stylized facts on major trends and variations and illustrative applications

a dynamic analysis of interfuel substitution in u s industrial energy demand using data for 1960 92 to analyze interfuel substitution in the u s industrial sector a dynamic linear logit model is shown to provide superior global properties than a comparable dynamic translog model confirming earlier static results by t j considine 1989 the linear logit model provides a direct unbiased estimate of the rate of dynamic adjustment indicating a median response lag of less than two years excluding fuels used for nonenergy purposes yields larger estimates of the price elasticities for coal and oil and indicates generally greater potential for interfuel substitution than when using aggregate data

determination of employment with wage and price speculation the purpose of this paper is to investigate whether aggregate fluctuations in employment may be explained within a market clearing framework as intertemporal substitution in labor supply and demand an intertemporal substitution model for the firm is derived this model is estimated with a lucas rapping type supply equation empirical results with finnish data lend support to the intertemporal substitution model particularly concerning the demand function specification on the other hand the results for the supply equation are somewhat mixed being rather sensitive to the dynamic specification

on the dynamic effects of oil price shocks a study using industry level data abstract this paper analyzes the effects of oil price shocks on demand and supply in various industries the impulse responses of identified var models indicate that for industries that have a large cost share of oil such as petroleum refinery and industrial chemicals oil price shocks mainly reduce supply in contrast for many other industries with the automobile industry being a particularly important example oil price shocks mainly reduce demand the paper suggests that oil price shocks influence economic activities beyond that explained by direct input cost effects possibly by delaying purchasing decisions of durable goods

the general equilibrium costs and impacts of oil price shocks in newfoundland and labrador abstract the 2014 2015 dramatic drop in world oil prices had devastating impacts on a global scale we analyse economic costs and impacts of a negative oil price shock following the 2014 2015 decrease in oil prices on the provincial economy of newfoundland and labrador canada we use a dynamic computable general equilibrium model to estimate a drop in oil prices by inputting the estimated effect as a direct impact to royalties which are the land input in the oil and gas sector of the provincial economy we provide sensitivity to account for the duration and magnitude of the shock as well as the timing of recovery our results suggest that a shock in the price of oil will have its most significant impact on gdp in the initial years over the first five years the reduction in gdp due to this shock would be roughly 2 1 of gdp in our most realistic shock scenario but could be much higher in other scenarios considered a sharp drop in gdp over the first five years will be mitigated somewhat in the long run as the growth in oil prices rises however negative long run impacts to gdp persist due to the oil price shock in 2014 2015 and will worsen if there is a prolonged shock

an empirical and forecasting analysis of the bioenergy market in the eu28 region evidence from a panel data simultaneous equation model this study improves upon and applies a comprehensive panel data simultaneous equation model to the european union eu28 region s bioenergy market the goals are to estimate bioenergy quantities in domestic and international markets for the period from 1990 to 2013 and to apply a forecasting analysis for the eu28 s domestic and international bioenergy markets for the period of 2014 2020 the results demonstrate that biomass harvest and the domestic price in a domestic market have a significant influence on the supply function additionally domestic price has a negative relationship with the bioenergy market domestic demand in international markets competitive import prices play a primary role in the development of the bioenergy market import demand export prices and gdp also have primary influences on the export demand for bioenergy moreover the exchange rate has a positive and significant effect on export demand the results of a forecasting analysis for the future period of 2014 2020 has predicted slight increases in domestic supply domestic demand and import trends on the other hand it also predicted a sharp decline in the export demand trend between those same years this study contributes to the literature by providing policymakers and other energy policy stakeholders a reliable forward looking analysis of the potential condition of the domestic and international bioenergy markets in the eu28 region through the end of 2020

the intertemporal dimension of neoclassical production theory abstract the aim of this survey paper is to provide a guide to the literature on optimal dynamic factor demands to the non specialist reader interested in applied work we start with the distinction between variable and quasi fixed factors of production and use these to characterize the firm s temporary equilibrium we then review the optimal intertemporal behaviour of the firm using the notion of adjustment costs as a means to solve the firm s optimization problem this process gives rise to a system of interrelated dynamic factor demands in a flexible accelerator format theoretical difficulties and empirical limitations of this model are discussed this fact leads us to review the theory of intertemporal duality we next analyze the issue of expectations in this class of dynamic models a section reviewing the empirical work on dynamic factor demands follows after which we offer some concluding remarks

quasi fixed inputs in u s and japanese manufacturing a generalized leontief restricted cost function approach in this paper a generalized leontief variable cost function is develope d which permits analytical derivation of steady state levels of quasi fixed inputs and capacity output and does not require specification of a numeraire input this framework is then used to evaluate the fa ctor demand patterns of japanese and u s manufacturing based on bot h one quasi fixed capital input and two quasi fixed capital and la bor input specifications and both static and dynamic optimization t he findings provide evidence of considerable flexibility of demand re sponses in japan which may have contributed to japan s relatively st rong economic performance in the volatile 1970s copyright 1988 by mit press

dynamic factor demand equations in u s and canadian agriculture abstract this research provides one of the first empirical estimates of a data based dynamic factor demand model for american and canadian agriculture models such as these deserve more widespread use in the empirical analysis of agriculture these models have the advantage that they do not impose inappropriate dynamics on the data rather they permit the data to select the appropriate dynamics we use a model originally developed by anderson and blundell this model is a general first order dynamic model which contains as testable hypothesis several simpler models this model permits us to estimate the long run agricultural production structure as a subset of the dynamic parameter estimates we will test this long run structure for symmetry homotheticity and neutral technical change the estimated models may be used to test for three alternative dynamic structures in the limit dynamics may not be needed and we can test for the static long run equilibrium model two intermediate cases are the autoregressive and the partial adjustment models which are simpler than the general model but still include dynamics our results suggest that the long run equilibrium model is unsatisfactory in both countries a dynamic model is needed in both countries the two more restricted dynamic models are rejected the general dynamic model is required in canada the long run equilibrium structure is homothetic with neutral technical change in the united states homotheticity is also accepted but neutral technical change is rejected

productivity growth in u s agriculture under dynamic adjustment a dynamic measure of productivity growth adjusted for deviations from the long run equilibrium is established within an adjustment cost framework an empirical application to u s agriculture is presented which permits identifying the dynamic linkages between technical change and productivity growth in u s agriculture total factor productivity as dynamically measured grew at 1 50 per annum the combined effect of scale quality adjusted input growth and long run disequilibrium input use contributes only 3 44 of the growth while technical change dominates the growth of total factor productivity

rebound directed technological change and aggregate demand for energy abstract we analyse the long run role of energy in aggregate production the factor share of energy has been remarkably constant despite the relative decline in the price of energy we analyse possible explanations for this observation ruling out the idea that endogenous directed technological change has led to a failure of energy augmenting technology to keep pace with labour augmenting technology instead we propose a model in which a combination of income and substitution effects has driven both shifts in consumption patterns towards existing energy intensive goods and the emergence of new such goods

the effect of the german and british environmental taxation reforms a simple assessment abstract this article implements a simple econometric approach to assess the effect of the environmental tax reforms introduced in germany and the uk despite the very simple econometric approach adopted in this paper in the case of the energy demand our results do not differ markedly from those obtained from complicated multi sectoral econometric models in the case of the labour demand our results differ from the estimates obtained from econometric models where the employment level is not directly influenced by the energy price on the other hand our results are more similar to those obtained from models where the level of employment is directly influenced by the energy price confirming the findings of bosquet 2000 environmental tax reform does it work a survey of the empirical evidence ecological economics 34 19 32 and oecd 2004 environment and employment an assessment working party on national environmental policy oecd paris we conclude that environmental tax reforms can deliver substantial reductions in energy consumption while having small effects on the level of employment effect which can be positive depending on the size of the reduction in the labour costs and the value of cross price elasticities

expectations and factor demand this paper develops and estimates a model of interrelated factor demand with rational expectations in the presence of internal adjustment costs invariant technological parameters are distinguished from the firm s adjustment parameters which change when the exogenous processes faced by the firm change the capital demand equation is derived by solving the euler equations which stem from minimization of the present value of costs future exogenous variables are supplied from solutions of arima equations the model is tested on postwar quarterly data for u s manufacturing a regime change in the process for energy prices is simulated as is a temporary suspension of the investment tax credit

real flexibility and financial structure an empirical analysis i examine the empirical relation between real flexibility and financial structure i test whether real flexibility increases debt capacity by lowering default risk and making assets more marketable or decreases debt capacity by facilitating risk shifting and asset substitution i measure real flexibility as the sensitivity of marginal production and investment decisions to variations in the economic environment i find that financial leverage is negatively related to production flexibility but positively related to investment flexibility this split in results suggests that although asset substitution facilitated by investment flexibility can be prevented contractually risk shifting facilitated by production flexibility is intractable copyright 2003 oxford university press

factor substitution in u s manufacturing does plant size matter we use micro data for 10 412 u s manufacturing plants to estimate the degrees of factor substitution by industry and by plant size we find that 1 capital labor energy and materials are substitutes in production and 2 the degrees of substitution among inputs are quite similar across plant sizes in a majority of industries two important implications of these findings are that 1 small plants are typically as flexible as large plants in factor substitution consequently economic policies such energy conservation policies that result in rising energy prices would not cause negative effects on either large or small u s manufacturing plants and 2 since energy and capital are found to be substitutes the 1973 energy crisis is unlikely to be a significant factor contributing to the post 1973 productivity slowdown

recursive factor of production interrelations and endogenous cycling a multivariate linear rational expectations equilibrium version of the lucas prescott investment model is developed to study the behavior of factors of productions with recursive interrelations the connection between these interrelations and endogenous cycling is established in a testable way maximum likelihood estimates using annual postwar aggregate u s manufacturing data provide strong evidence of capital labor interrelations that induce a labor overshooting type of endogenous cycling this raises questions for the methodology of current real business cycle models which rule out the possibility of such interrelations copyright 1991 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

r d production structure and rates of return in the u s japanese and german manufacturing sectors a non separable dynamic factor demand model abstract the focus of this paper is an analysis of the production structure the demand for factor inputs and the rates of return in the manufacturing sector of three major industrialized countries the united states japan and germany the analysis is based on a dynamic factor demand model with two variable inputs labor and materials and two quasi fixed inputs capital and rd also for all countries the speed of adjustment for capital is found to be higher than that for r d

energy price energy efficiency and capital productivity empirical investigations and policy implications abstract the immediate effect of carbon pricing policy is to raise energy costs which in turn reduces energy consumption either through induced capital under utilization or investments in new energy efficient capital the latter mechanism which implies improvements in energy efficiency is realized in the long run while the former which has implications for capital productivity tends to occur in the short run we employ panel vector autoregressions as well as co integration and error correction techniques to identify these short and long run relationships including their differences across canadian industries

dynamic factor demand systems and the adjustment speed towards equilibrium most models of factor demand can be grouped into two categories the first is static models which consistently account for substitution among several factors without imposing a priori restrictions on the production structure such models utilize flexible functional forms to represent the underlying technology however they impose strict restrictions on the dynamic behaviour of the technology in that either full or partial static equilibrium is assumed studies in this group providing a rationale for modelling some input factors as fixed in the short run include brown and christensen 1980 and kulatilaka 1985 a partly dynamic approach was suggested by pindyck and rotemberg 1983 who explicitly model the adjustment costs of some factors however the underlying production technology is still regarded as static the second category consists of dynamic models that incorporate cost of capital stock adjustments such models often apply a single factor and typically impose ad hoc assumptions in both categories the researcher selects the inputs which are not regarded as completely variable mostly on the basis of a priori assumptions in this paper we will focus on implications of a dynamic modelling of factor demand systems it is clear that a firm will adjust to price changes only when it is profitable to do so accordingly the cost of adjustment may serve as a rationale for why different factors may adjust towards equilibrium at different speeds hence when we are able to model the adjustment speed of the different factors we are also able to parametrically test for the

inventories as factors of production and economic fluctuations this paper presents a theory of inventory investment by stage of processing and uses it to examine the role of inventory investment in economic fluctuations the model in which inventories are treated as factors of production is estimated for four durable goods industries three conclusions emerge from the estimation first the estimates generally satisfy the theoretical restrictions second the elasticity of inventory demand with respect to output is high indicating an important accelerator effect finally the estimates suggest that shifts in the demand for inventories are an important source of economic fluctuations copyright 1989 by american economic association

short and long term equilibria relationships between first and third generation dynamic factor demand models abstract first generation dynamic models of input demands are theoretically inferior to third generation models yet their simplicity makes them attractive for estimation purposes moreover first generation models can be shown to be generically related to third generation models and under certain assumptions input demand expressions in a third generation model collapse to those of the first generation seemingly offering a short cut for estimation however empirical comparisons suggest that first generation specifications do not afford a reasonable approximation to input functions embedded in more complex third generation models furthermore the reduced form coefficients do not permit identification of third generation model structures

liberalisation consumption heterogeneity and the dynamics of energy prices in this study the methodology var and the cointegration analysis are used to examine the dynamic interaction among the energy prices of the competitor energy sources in a liberalised market data from the uk market were applied and models for the residential and industrial sectors were developed our results indicate the existence of long run relationships between the energy prices before and after the liberalisation implying the possibility of substitution among the different forms of energy however the results appear to be also largely influenced by external variables not included in the models that may be reducing the importance of the energy prices over their own evolution and offsetting the basic substitution relationships the general results of the impulse response functions both for the residential and industrial sectors present low statistical significance which seems to be due to the still slow rate of adjustment of the energy market to price changes along with the immaturity of the liberalisation process taking into consideration the results some routes for future research are pointed out namely the need to include in the analysis variables which would proxy the general state of the economy

the mis specification of production costs in production smoothing models estimation results obtained with production smoothing models are often imprecise and sensitive to normalisation rules it is argued here that production costs in these models can be better specified in terms of production factor costs the resulting factor demand model with inventories leads to more efficient estimation results and normalisation rules become even redundant furthermore the smoothing role of inventories with respect to production factors is discussed c 1997 elsevier science s a

structural models of dynamic factor demands with nonstatic expectations an empirical assessment of alternative expectations specifications until recently little literature existed on incorporation of nonstatic price and output expectations into empirically implementable factor demand models for example the vast literature on flexible functional forms is almost completely characterized by static expectations on prices and output as well as instantaneous adjustment to desired levels of demand more recent studies have incorporated increasingly complex theoretical and econometric structures the literature along the lines of fuss 1976 and berndt fuss and waverman 1979 bfw incorporates endogenous determination of dynamic adjustment structure but retains a static expectations assumption on the other hand most current rational expectations models following the lead of thomas sargent and robert lucas make very restrictive simplifying assumptions on the deterministic economic structure in order rigorously to specify the complex stochastic structure implied by the rational expectations assumption a thrid category of model represented by pindyck and rotemberg 1983 relies on an instrumental variable approach to ensure error orthogonality and hence consistency with the rational expectations assumption this procedure allows for a more complete structural specification but does not explicitly incorporate an expectations process this paper represents a step toward a synthesis of the structural and stochastic approaches to dynamic input demand modeling with emphasis on both theoretical foundations and empirical tractability in this approach approximations to rational expectations and certainty equivalence are used explicitly to incorporate anticipatory behavior of firms into the structural model of dynamic factor demands theoretically this is accomplished without sacrificing rich economic structure a structural factor demand model is developed which includes both stock relationships and expectations formation based on an explicit dynamic optimization framework empirically the focus is on avoiding complex stochastic structures that are of little use to most empirical researchers all of the expectational models are empirically straightforward to implement and yet incorporate the important theoretical and empirical structure required for detailed analysis of short and long run behavior two issues must be addressed to formalize and implement the model the

the expansion of renewable energies and employment effects in germany the promotion of electricity produced from renewable energy is a high priority of the european union as well of its member states the german government wants to increase the share of renewable energies from about 5 to 12 by 2010 to attain this goal the german government has introduced compulsory compensation schemes for electricity produced from renewable energy fed into the public grid this paper examines the economic impact of this policy employing an econometric model particular emphasis was given to employment effects in general we distinguish two effects 1 an expansive effect resulting from additional investments and 2 a contractive effect resulting from an increase in the production cost of power the first effect will dominate during the first years and lead to an increase in employment of approximately 33 000 new jobs however the contractive effect will offset these gains and lead to a slightly negative employment balance by 2010

the own wage elasticity of labor demand a meta regression analysis firms labor demand responses to wage changes are of key interest in empirical research and policy analysis however despite extensive research estimates of labor demand elasticities remain subject to considerable heterogeneity in this paper we conduct a comprehensive meta regression analysis to re assess the empirical literature on labor demand elasticities building on 942 elasticity estimates from 105 different studies we identify sources of variation in the absolute value of this elasticity heterogeneity due to the theoretical and empirical specification of the labor demand model different datasets used or sectors and countries considered explains more than 80 of the variation in the estimates we further find substantial evidence for the presence of publication selection bias as estimates of the own wage elasticity of labor demand are upwardly inflated

cost specification and firm behaviour in a hotelling model of resource extraction in applied resource economics much attention has been focused on the ability of the hotelling model to explain observed firm behavior in this paper a preliminary specification search is performed to determine the appropriate cost function parameterization for the firms in the sample before proceeding to the estimation of the euler equation once a cost function specification is chosen the corresponding euler equation is estimated via the generalization method of moments gmm which allows for better estimates of the euler equations than in previous studies even with the preliminary specification search and the use of gmm estimation the behavior of the panel of fourteen canadian copper mining firms in the data set examined does not seem to be consistent with the basic hotelling model used

relative risk aversion around the world abstract in this letter the hypothesis of constant relative risk aversion is examined for 15 countries using property liability insurance data for more than half the cases it is shown that crra can not be rejected following that the degree of relative risk aversion is estimated and found to usually lie between one and two

an econometric analysis of fluctuations in aggregate labor supply and demand the paper contains a simple equilibrium model of the labor market the supply function allows for intertemporal substitution in response to real wage fluctuations and the demand function allows for adjustment costs on employment the supply and demand functions both solve quadratic partial adjustment problems driven by rational expectations about future real wages the market equilibrium also solves a partial adjustment problem driven by rational expectations about future preference and technology shocks two related issues are emphasized the identification of dynamic labor supply and demand functions and the theoretical interpretation of serial correlation in employment and real wages when the supply and demand shocks are assumed to be ar 1 processes which are not causally related the model delivers a simple structure for the equilibrium process for employment and real wages which is a restricted var 2 this simple structure facilitates the interpretation of summary statistics on the time series properties of observed employment and real wage series the supply and demand functions can both be locally identified using only employment and real wage data an illustrative application is presented using u s manufacturing data for the period 1948 1971

an adjustment cost model of long term employment in japan summary a dynamic factor demand model is presented which pays special attention to the prevalence of a longterm employment relationship in japan the model is based on the representation of technology by a variable cost function with adjustment costs for employment and capital stock where the variable cost consists of the sum of overtime costs and materials costs with employment being quasi fixed and scheduled hours institutionally regulated short run adjustments are mostly made by overtime hours application to a time series data on the japanese electrical machinery industry indicates quasi fixity of capital and employment and reproduces short run overshooting of overtime hours to compensate for the sluggish adjustment of employment

capacity utilization and depreciation in use in this paper the effect capacity utilization has on the depreciation of capital goods is studied starting from a quadratic approximation to a normalized short run cost function expressions for the optimal rate of capacity utilization the demands for labour and energy and for investment are obtained investment is a function of past capital stock expected future capital stock expected future relative prices and expected future depreciation rates expectations are modelled via instruments the model is tested using us total manufacturing quarterly data depreciation dependent upon usage is found to be both statistically and economically significant

green jobs economic impacts of renewable energy in germany abstract the labor market implications of large investment into renewable energy re are analyzed in this text although a growing re industry can be observed in germany the overall effect of large increases of re based electricity and heat generating technologies on the german economy require a careful model based analysis the applied model panta rhei has been used among others to evaluate the german energy concept in 2010 it takes positive and negative impacts of re into account the paper shows the overall effects under different assumptions for fossil fuel prices domestic installations and international trade the results are sensitive to assumptions on the development of re world markets and german exports to these markets almost all of these scenarios exhibit positive net employment effects under medium assumptions net employment of re expansion will reach around 150 thousand in 2030 only with assumptions for german re exports below today s level net impacts are slightly negative gross employment will increase from 340 thousand in 2009 to between 500 and 600 thousand in 2030

inventories employment and hours abstract this paper develops a model that integrates inventory and labor decisions we extend a model of inventory behavior to include a detailed specification of the role of labor input in the production process distinguishing between employment hours and effort per worker we estimate jointly the euler equations for inventories and employment a labor compensation schedule and an hours requirement function with the cross equation restrictions imposed the econometric results shed light on several important topics including the shape of the marginal cost of output the role of labor hoarding as an explanation of pro cyclical productivity and the persistence of inventory stocks

dynamic factor demands and the effects of energy price shocks a dynamic model is used to understand how sharp changes in energy prices affect investment behavior employment and energy use the authors discuss the theory behind their model selection model specifications estimation methods and data list parameter estimates and elasticities for the selected model and describe the simulations they conclude that 1 the data strongly reject the hypothesis of constant returns to scale within their specification of aggregate production 2 the data indicate adjustment costs on labor are small and 3 their results help reconcile some of the conflicting estimates of energy demand elasticities appearing in recent literature 23 references 3 figures 3 tables

technical efficiency and u s manufacturing productivity growth this paper establishes that new inputs increase technical efficiency levels for u s manufacturing over the period 1950 1998 intermediate inputs exhibited higher rates of efficiency growth than labor and capital efficiency adjusted productivity growth annually averaged 0 4 percentage points above measured growth the gap between efficiency adjusted and measured productivity growth arises from aggregating inputs using observed and not efficiency adjusted cost share weights in the calculation of measured growth specifically the decline in efficiency adjusted material cost shares compared to the measured shares coupled with the comparatively high material input growth rate was the main source of the productivity gap

renewable energy and employment in germany abstract the positive impacts of an increasing share of renewable energy on the mitigation of climate change as well as on the decrease of the dependency of energy imports are indisputable however one persistent problem for the german economy has been its high level of unemployment in the recent past therefore any policy strategy will be measured also by its net impact on the labor market the paper describes the results of a study that models this impact and is novel within three respects firstly an input output vector for the renewable energy sector was developed based on the results of more than 1000 interviews with an extensive questionnaire secondly gross and net effect of two different policy scenarios for germany until 2030 were calculated and thirdly the approach varies from earlier studies by its explicit modeling of export and foreign trade effects

labor demand effects of rising electricity prices evidence for germany abstract germany continues to play a pioneering role in replacing conventional power plants with renewable energy sources while this might be beneficial with respect to environmental quality it also implies increasing electricity prices the extent to which this is associated with negative impacts on employment depends on the interrelationship between labor and electricity as input factors in the production process in this paper we estimate cross price elasticities between electricity and heterogeneous labor for the german manufacturing sector we use administrative linked employer employee micro data combined with information on sector level electricity prices and usage over the period 2003 2007 we find positive but small conditional cross price elasticities of labor demand with respect to electricity prices which means that electricity as an input factor can be replaced by labor to a limited extent when the production level is held constant in the case of adjustable output we find negative unconditional cross price elasticities implying that higher electricity prices lead to output reductions and to lower labor demand with low and high skilled workers being affected more than medium skilled resulting adverse distributional effects and potential overall job losses may pose challenges for policy makers in securing public support for the german energy turnaround

dynamic factor demands and market structure under rational expectations some estimates for the italian manufacturing system this paper deals with a dynamic model of the behaviour of firms under rational expectations the adjustment cost framework is followed to describe production technologies the objective of firms is to maximize the stream of future profits under rational expectation first order conditions for the optimum are derived with respect to input demands and one output supply the output market structure is modelled in order to test price taking behaviour the adjustment costs of quasi fixed inputs are internal and interrelated the model is estimated for the italian manufacturing system with encouraging results

dynamic factor demands under rational expectations we model the industrial demands for structures equipment and blue and white collar labor in a manner consistent with rational expectations and stochastic dynamic optimization in the presence of adjustment costs but allowing generality of functional form we represent the technology by a translog input requirement function that specifies the amount of blue collar labor needed to produce an output level given quantities of three quasi fixed factors nonproduction workers equipment and structures a complete description of the production structure is obtained by simultaneously estimating the input requirement function and three stochastic euler equations we find adjustment costs are small in total but large on the margin and differ considerably across factors

consistent tariffs with dynamic supply response abstract this paper models a large importer of a competitively produced good for which there are nonlinear adjustment costs in production if producers have rational expectations and the importer is unable to make a credible commitment regarding future tariffs market power may be disadvantageous this is more likely to occur when the difference between short and long run elasticities of supply are large this result depends on the particular subgame perfect equilibrium that is chosen if producers were capable of strategic behavior other equilibria which rely on trigger strategies would be reasonable and market power could no longer be disadvantageous

estimating dynamic dual models under nonstatic expectations in this paper we derive a system of equations depicting agents dynamic decision rules under nonstatic price expectations based on the adjustment cost model of the firm the integrability conditions which can serve to guide the specification of flexible functional forms are established a two stage econometric model permitting empirical examination of both the expectations formation process and the dynamic structure of the industry is estimated using two different data series for u s production agriculture the estimation results suggest evidence of the presence of nonstatic price expectations in dynamic dual models for u s production agriculture

industrial electricity demand and energy efficiency policy the role of price changes and private r d in the swedish pulp and paper industry abstract the objective of this paper is to analyze electricity demand behaviour in the swedish pulp and paper industry in the context of the increased interest in so called voluntary energy efficiency programs in these programs tax exemptions are granted if the participating firms carry out energy efficiency measures following an energy audit we employ a panel data set of 19 pulp and paper firms and estimate both the own and cross price elasticities of electricity demand as well as the impact of knowledge accumulation following private r d on electricity use the empirical results show that electricity use in the swedish pulp and paper industry is relatively own price insensitive and the self reported electricity savings following the voluntary so called pfe program support the notion of important information asymmetries at the company level however the results display that already in a baseline setting pulp and paper firms tend to invest in private r d that have electricity saving impacts and our model simulations suggest that up to about one third of the industry sector s self reported electricity savings in pfe could be attributable to pure baseline effects future evaluations of voluntary energy efficiency programs must increasingly recognize the already existing incentives to reduce energy use in energy intensive industries

assessing a disaggregated energy input using confidence intervals around translog elasticity estimates the role of energy in the production of manufacturing output has been debated extensively in the literature particularly its relationship with capital and labor in an attempt to provide some clarification in this debate a two step methodology was used first under the assumption of a five factor production function specification we distinguished between electric and non electric energy and assessed each component s relationship with capital and labor second we calculated both the allen and price elasticities and constructed 95 confidence intervals around these values our approach led to the following conclusions that the disaggregation of the energy input into electric and non electric energy is justified that capital and electric energy and capital and non electric energy are substitutes while labor and electric energy and labor and non electric energy are complements in production and that capital and energy are substitutes while labor and energy are complements

tax policy and business fixed investment in the united states abstract this paper derives and estimates models of nonresidential investment behavior in which current and future tax conditions directly affect the incentive to invest the estimates suggest that taxes have played an independent role in affecting postwar u s investment behavior particularly for investment in machinery and equipment in addition the paper develops a method for assessing the impact of tax policy on the volatility of investment when such policy is endogenous illustrative calculations using this technique based on the paper s empirical estimates suggest that tax policy has not served to stabilize investment in equipment or nonresidential structures during the sample period

monetary policy response to oil price shocks how should monetary authorities react to an oil price shock this paper shows that in a noncompetitive economy policies that perfectly stabilize prices entail large welfare costs hence explaining the reluctance of policymakers to enforce them the policy trade off is nontrivial because oil energy is an input to both production and consumption as welfare maximizing policies are hard to implement and communicate i derive a simple interest rate rule that depends only on observables but mimics the optimal plan in all dimensions the optimal rule is hard on core inflation but accommodates oil price changes

future perspectives of international bioenergy trade abstract according to the iea world energy outlook 2012 primary demand for bioenergy will strongly increase up to the year 2035 the demand for biofuels and biomass for electricity is expected to triple these changes will have an impact on the regional balance of demand and supply of bioenergy leading to both increasing trade flows and changes in trade patterns the gfpm timer and poles models have been selected for a detailed comparison of scenarios and their impact on global bioenergy trade in ambitious scenarios 14 26 of global bioenergy demand is traded between regions in 2030 the model scenarios show a huge range of potential bioenergy trade for solid biomass in ambitious scenarios bioenergy trade ranges from 700 mt to more than 2 500 mt in 2030 for liquid biomass the ambitious scenarios show a bioenergy trade in the range of 65 360 mt in 2030 considering the currently very small share of internationally traded bioenergy this would result in huge challenges and require tremendous changes in terms of production pretreatment of biomass and development of logistic chains

energy transition under irreversibility a two sector approach in this paper we analyze the optimal energy transition of a two sector economy energy and final goods with exhaustible oil reserves a renewable source of energy and a pollution threat the latter corresponds to a pollution threshold above which a part of the capital is lost following flooding for instance we show that the optimal energy transition path may correspond to a corner regime in which the economy starts using both resources then crosses the pollution threshold and therefore loses a part of its capital at the end the sole adoption of the renewable energy is optimal only in the long run this result is in line with the asymptotic energy transition arguments stating that the transition to clean energy may happen only in the long run we also show that economy reduces the use of energy resource as long as the productivity of capital and energy services is high therefore public policies should promote investments in energy innovation that targets productive sector home appliances and buildings and helps to save both money and energy we extend the present model to allow for additional investment in energy saving technologies our main results show that this additional investment favours the energy transition in the sense that it increases the time within which the economy may experience the catastrophe and the welfare of the society for policy implications economic instruments such as taxes on dirty energy subsidies on clean energy or incentives for energy saving technologies need to be implemented in order to promote the energy transition this is particularly important for developing countries that mostly rely on polluting energy resources and are the most vulnerable to climate change but those economic instruments should be carefully designed in line with the asymptotic energy transition result

financial structure production and productivity evidence from the u s food manufacturing industry this study integrates production and financing to examine the impacts of financial structure change on the production profitability and productivity growth in the u s food manufacturing industry empirical results show that during the period covered by this study agency cost associated with increased debt use by this industry negatively affected its output growth input demand profitability and overall productivity growth dividend payment positively contributed to the production and performance of this industry via signaling benefit however the negative effects of increased debt use by this industry far outweighed the positive contribution of dividend payment the u s food industry achieved a 0 9 average annual productivity growth which came primarily from technological progress and capital adjustment the rapid increase in debt use by this industry was responsible for slowing down the pace of productivity growth via its negative contribution to the total factor productivity growth capital expansion was the principal driver of output growth and profitability in this industry

international bioenergy trade a review of past developments in the liquid biofuel market policies aimed to promote biofuels locally had tremendous effects on global market developments across the past decade this article develops insights into the interaction of these policies and market forces via a comprehensive collection and analysis of international production and trade data it shows that world biofuel production and trade has grown exponentially from below 30 pj in 2000 to 572 pj in 2009 for biodiesel from 340 pj in 2000 to over 1540 pj in 2009 for fuel ethanol the eu has dominated world biodiesel whereas the us and brazil have led fuel ethanol production world net biofuel trade reached 120 130 pj in 2009 and was directed towards the most lucrative markets for biodiesel this has been the eu whose imports rose to 92 pj in 2008 and remained at 70 pj in 2009 regarding fuel ethanol both the us and the eu have been prime destinations for competitively priced exports the vast majority of which originated in brazil international biofuel trade is both supply and demand driven the demand side was shaped by support policies which generally increased the domestic market value of biofuels trade developed wherever these policies prices were not accompanied by respective measures it is found that import duties largely influenced trade volumes whereas trade routes were mainly driven by tariff preferences trade regimes appear to have been designed and adapted unilaterally along national interests causing market disruptions trade inefficiencies and disputes to avoid these it is important to explicitly consider international trade implications of national trade policies a prerequisite is to improve the understanding of the underlying complex and interwoven links within the market the current lack of adequate homogeneous international reporting of biofuel production and trade statistics could be bridged via internationally standardized custom clarifications trade factor interrelations also need to be investigated further

spillovers from publicly financed r d capital in high tech industries abstract this paper employs a dynamic production model to examine the short run effects of publicly financed r d capital on the cost structure of six high tech us manufacturing industries the results show that given an industry s output publicly financed r d capital reduces the variable production cost in all industries in addition an increase in publicly financed r d causes output to increase implying that producers as well consumers are better off despite the presence of strong monopoly power in some industries a low bound for the social rate of return to publicly financed r d is also calculated

interrelated factor demands for manufacturing a dynamic translog cost function approach abstract in this paper we report the results of estimating a joint model for labour capital and energy using the transcendental logarithmic cost function of christensen jorgenson and lau 1973 this allows us to determine both the own price and cross elasticities of substitution between labour capital and energy we combine a model of factor shares with a dynamic adjustment process for each factor we also impose on the cross equation restrictions necessary to provide additivity homogeneity and symmetry since the covariance matrix in systems of share relationships is singular we follow the suggestions of anderson and blundell 1982 and employ a mullivariate error corrrection model the results suggest that additivity symmetry and homogeneity restrictions do hold and that there are short run increasing returns to scale

how do banks adjust to changing input prices a dynamic analysis of u s commercial banks before and after the crisis abstract the 2000 2013 period was characterized by substantial regulatory monetary and technological change especially after the onset of the global financial crisis this study assesses the total impact of these policy shifts and technological changes on u s commercial banks short run and long run substitution elasticities an endogenous break test divides the sample into a pre crisis period and a post crisis period during the former period banks inputs tend to be inelastic substitutes after the onset of the crisis particularly the long run substitutability of most input factors decreases to even lower levels due to changes in both cost technology and economic conditions at the same time banks response to input price changes becomes more sluggish hence especially after the onset of the crisis banks have little flexibility regarding input factor usage and are thus sensitive to input price changes from a cost perspective

a literature survey on energy growth nexus abstract this paper provides a survey of the recent progress in the literature of energy consumption economic growth and electricity consumption economic growth causality nexus the survey highlights that most empirical studies focus on either testing the role of energy electricity in stimulating economic growth or examining the direction of causality between these two variables although the positive role of energy on growth has become a stylized fact there are some methodological reservations about the results from these empirical studies a general observation from these studies is that the literature produced conflicting results and there is no consensus neither on the existence nor on the direction of causality between energy consumption electricity consumption and economic growth as a policy implication to avoid from conflicting and unreliable results the authors may use the autoregressive distributed lags bounds test two regime threshold co integration models panel data approach and multivariate models including new variables such as real gross fixed capital formation labor force carbon dioxide emissions population exchange rates interest rates etc thus the authors should focus more on the new approaches and perspectives rather than by employing usual methods based on a set of common variables for different countries and different intervals of time

technological choices and regulation the case of the canadian manufacturing sectors the economic environment in which canadian manufacturing firms operate has changed substantially over the last 40 years technological changes new regulations deregulation and exogenous economic shocks all have been important aspects of this economic environment in this article we show how to include such changes in the economic environment faced by the firms in a behavioural model that includes the investment decision of the firm under uncertainty assumptions regarding the expectation formation process and technology are kept minimal we estimate the effects of innovations such as the free trade agreement the foreign investment review agency and the federal environmental policy on the economic decisions of fifteen canadian manufacturing sectors jel classification d24 choix de technologies et reglementation le cas des secteurs manufacturiers canadiens au cours des 40 dernieres annees l environnement economique des firmes manufacturieres canadiennes s est grandement transforme que ce soit a cause du changement technologique de la reglementation de vagues de dereglementation ou de chocs economiques exogenes les firmes ont du s adapter en modifiant leur technologie dans cet article nous montrons comment prendre en compte les changements de l environnement economique des firmes dans le cadre d un modele decisionnel de la firme en incertitude avec investissement les hypotheses concernant la technologie et les anticipations sont aussi generales que possible nous estimons l effet qu ont eu l accord de libre echange l agence de tamisage des investissements etrangers et la politique environnementale federale sur les choix de technologies des firmes de quinze secteurs manufacturiers canadiens

opportunities and barriers for international bioenergy trade recently the international trade of various bioenergy commodities has grown rapidly yet this growth is also hampered by some barriers the aim of this paper is to obtain an overview of what market actors currently perceive as major opportunities and barriers for the development of international bioenergy trade the work focuses on three bioenergy commodities bioethanol biodiesel and wood pellets data were collected through an internet based questionnaire the majority of the 141 respondents had an industrial background geographically two thirds were from mainly western europe with other minor contributions from all other continents results show that import tariffs and the implementation of sustainability certification systems are perceived as potentially major barriers for the trade of bioethanol and biodiesel while logistics are seen mainly as an obstacle for wood pellets development of technical standards was deemed more as an opportunity than a barrier for all commodities most important drivers were high fossil fuel prices and climate change mitigation policies concluding to overcome some of the barriers specific actions will be required by market parties and policy makers import tariffs for biofuels could be reduced or abolished linked to multinational trade agreements and harmonization including provisions on technical standards and sustainability requirements
