tracking the new economy using growth theory to detect changes in trend productivity abstract the acceleration of productivity after 1995 prompted a debate over whether the economy s underlying growth rate would remain high in this paper we draw on growth theory to identify variables other than productivity namely consumption and labor compensation to help estimate trend productivity growth we treat that trend as a common factor with two regimes high and low growth our analysis picks up striking evidence of a return in 1997 to the high growth regime nearly 25 years after a switch from high to low growth we find that both the common factor and regime switching aspects of the model are important for identifying changes in trend productivity and also show that the trend breaks are more difficult to detect with per capita as opposed to per hour based data because of persistent labor supply shifts finally we argue that our methodology is effective in detecting changes in trend in real time in the case of the 1990s the methodology would have signaled the regime switch by 1999 or within roughly six quarters of when it occurred according to the full sample

assessing the sustainability performances of industries business sustainability entails the incorporation of the objectives of sustainable development namely social equity economic efficiency and environmental performance into a company s operational practices companies that compete globally are increasingly required to commit to and report on the overall sustainability performances of operational initiatives the current indicator frameworks that are available to measure overall business sustainability do not effectively address all aspects of sustainability at operational level especially in developing countries such as south africa social criteria specifically do not receive due considerations this article proposes a new framework to assess the sustainability of operations in the manufacturing sector

unemployment and productivity in the long run the role of macroeconomic volatility abstract this paper presents a new empirical regularity between the volatility of productivity growth and long run unemployment for a given level of long run productivity growth a theoretical framework based on asymmetric real wage rigidities is shown to have the potential to rationalize this finding the model tends to fit u s long run unemployment better than a specification based on long run productivity growth only especially during the great moderation and the great recession

testing the technology interpretation of news shocks this article presents further evidence on the hypothesis of news driven business cycles i use a structural vector error correction model vecm approach to identify news shocks as in beaudry and lucke bl 2010 i document three facts first news shocks identified by bl are granger causal for us patent data second bl s analysis applied to german macro data reveals very similar patterns activity is largely driven by news and news shocks explain a sizable and increasing share of total factor productivity tfp variance at long horizons and third german news shocks are granger causal for german patent data and the pattern is again very similar to the us since patent data in the us and germany are almost uncorrelated the similarity is striking and strongly suggests a technology interpretation of news shocks

going one s own way drivers in developing business models for sustainability business models have received much attention in recent years due to their importance in the fundamental logic of every company this paper is based on a qualitative empirical research study conducted in cooperation with 10 austrian companies in 2014 it aims to investigate business models for sustainability in order to better understand how they operate and what the drivers for developing these business models are this is a cross industry sample covering companies showing notable sustainability activities in fact half of the companies were founded with the intention of complying with sustainability principles the results show that business models incorporating aspects of sustainability do not differ substantially from traditional business models however they do require specific adaptations and extensions furthermore the findings highlight the significance of company leaders in organizing change processes so as to encompass sustainable business practices the findings reveal that business models undergo constant change and that sustainability plays a central role both internally and externally the results gained allow for a deeper understanding of the motivational aspects and drivers needed in developing business models for sustainability and serve as a solid basis for further research in this field

factor demand linkages technology shocks and the business cycle abstract this paper argues that factor demand linkages can be important for the transmission of both sectoral and aggregate shocks we show this using a panel of highly disaggregated manufacturing sectors together with sectoral structural vars when sectoral interactions are explicitly accounted for a contemporaneous technology shock to all manufacturing sectors implies a positive response in both output and hours at the aggregate level otherwise there is a negative correlation as in much of the existing literature furthermore we find that technology shocks are important drivers of the business cycle

a framework for strategic sustainable development the purpose of this paper is to give a comprehensive and cohesive description of the most recent version of the framework for strategic sustainable development fssd and also to describe and discuss the overall method for developing the fssd elaborate on the general rational for and general benefits of a framework of this type and validate benefits of the fssd through examples of its application the purpose is also to point to pertinent future work in preparation of this paper we have reviewed previous publications and other documents related to the fssd and reflected on the 25 year learning process between scientists and practitioners we conclude that the fssd has proven to aid organizations in thoroughly understanding and putting themselves in context of the global sustainability challenge and to move themselves strategically towards sustainability i e to stepwise reduce their negative impacts on ecological and social systems at large while strengthening the own organization through capturing of innovation opportunities including new business models exploration of new markets and winning of new market shares and through reduced risks and operation costs specifically we conclude that the fssd aids more effective management of system boundaries and trade offs makes it possible to model and assess sustainable potentials for various materials and practices before investments are made and offers the possibility for more effective collaboration across disciplines and sectors regions value chains and stakeholder groups we also conclude that the fssd makes it possible to prevent damages even from yet unknown problems and not the least to guide selection development and combination of supplementary methods tools and other forms of support which makes it possible to increase their utility for strategic sustainable development finally we have shown that the fssd is useful for structuring transdisciplinary academic education and research several examples of ongoing fssd related research as well as ideas for future work are given

the cyclical behavior of the price cost markup countercyclical markups constitute the key transmission mechanism for monetary and other demand shocks in new keynesian models this paper tests the foundation of those models by studying the cyclical properties of the markup of price over marginal cost the first part of the paper studies markups in the aggregate economy and the manufacturing sector we use bils s 1987 insights for converting average cost to marginal cost but do so with richer data we find that all measures of markups are either procyclical or acyclical moreover we show that monetary shocks lead markups to fall with output the second part of the paper merges input output information on shipments to the government with detailed industry data to study the effect of demand changes on industry level markups industry level markups are found to be acyclical in response to demand changes

current real business cycle theories and aggregate labor market fluctuations hours worked and the return to working are weakly correlated traditionally the ability to account for this fact has been a litmus test for macroeconomic models existing real business cycle models fail this test dramatically we modify prototypical real business cycle models by allowing government consumption shocks to influence labor market dynamics this modification can in principle bring the models into closer conformity with the data our empirical results indicate that it does

the cyclical and secular behaviour of the labour input comparing efficiency units and hours worked summary a monthly labour input series designed to correct for the fact that all hours worked are not of the same quality is constructed and its properties compared with unadjusted hours worked this efficiency units series is constructed from bls data on hours worked and earnings by age and sex the cyclical fluctuations displayed by the efficiency units series are smaller on average than those displayed by hours worked although the difference is not large however the secular behaviour of the series is quite different hours worked per capita displays a significant positive trend while efficiency units per capita does not

sustainable development and the challenge of innovation abstract innovation does not automatically lead to societal progress as is implicitly assumed in technology push oriented policies this assumption is an inheritance of the enlightenment i e the belief that science will automatically lead to a better quality of life the strive for sustainable development needs an approach towards innovation that can be characterised as society pull the society has to decide which balance of economical ecological and social goals are to be met society pull can be organised by developing shared perspectives for the future which are inspiring for public and private policy makers and investors in this paper this is worked out as transition management a process approach directing innovation towards sustainable development a crucial aspect of transition management is that innovation is no longer driven by the past but attracted by the future

measures of per capita hours and their implications for the technology hours debate structural vector autoregressions give conflicting results on the effects of technology shocks on hours the results depend crucially on the assumed data generating process for hours per capita we show that the standard measure of hours per capita and productivity have significant low frequency movements that are the source of the conflicting results hodrick prescott hp filtered hours per capita produce results consistent with those obtained when hours are assumed to have a unit root we show that important sources of the low frequency movements in the standard measure are sectoral shifts in hours and the changing age composition of the working age population when we control for these low frequency components to determine the effect of technology shocks on hours using long run restrictions we get one consistent answer hours decline in the short run in response to a positive technology shock we further extend the analysis by examining the effects of demographic controls on the impulse responses to investment specific technology shocks our results are less conclusive

sustainable business model adoption among s p 500 firms a longitudinal content analysis study in this study we examine the diversity of sustainable business models adopted by the largest global corporations those listed in the s p 500 index over the period 2005 2014 we examine press release communications during this period which represent public data about business relevant events we expect that examining this communication can reveal longitudinal patterns in the adoption of sustainable business activities and models empirically we utilize academic and practitioner expert panels to build a set of keywords across nine sustainable business model archetypes and utilize automated content analysis to examine the breadth and nature of a firm s sustainable business activities and practices we find evidence of the increasing prominence of different types of sustainable business models over time in particular the results show that large capitalized firms have mostly adopted the environmentally oriented archetypes and to much lesser extent the societal and organizational ones

fiscal policy in the aftermath of 9 11 this paper investigates the nature of u s fiscal policy in the aftermath of 9 11 we argue that the recent declines in the government surplus and tax rates cannot be accounted for by either the state of the u s economy as of 9 11 or as the typical response of fiscal policy to a large exogenous rise in military expenditures our evidence suggests that had tax rates responded in the way they normally do to a large fiscal shock aggregate output would have been lower and the surplus would not have changed by much our results do not bear directly on the desirability of the decline in tax rates or the surplus after 9 11

stochastic trends and economic fluctuations are business cycles mainly the result of permanent shocks to productivity this paper uses a long run restriction implied by a large class of real business cycle models identifying permanent productivity shocks as shocks to the common stochastic trend in output consumption and investment to provide new evidence on this question econometric tests indicate that this common stochastic trend cointegration implication is consistent with postwar u s data however in systems with nominal variables the estimates of this common stochastic trend indicate that permanent productivity shocks typically explain less than half of the business cycle variability in output consumption and investment copyright 1991 by american economic association

comparing dsge var forecasting models how big are the differences abstract i generate priors for a vector autoregression var from a standard real business cycle rbc model an rbc model with capital adjustment costs and habit formation and a sticky price model with an unaccommodating monetary authority the response of hours worked to a tfp shock differs sharply across these models i compare the accuracy of forecasts made from each of the resulting dynamic stochastic general equilibrium vector autoregression dsge var models despite having different structural characteristics the dsge vars are comparable in terms of forecasting performance as in previous work dsge vars compare favorably with atheoretical vars

can long run restrictions identify technology shocks gali s innovative approach of imposing long run restrictions on a vector autoregression var to identify the effects of a technology shock has become widely utilized in this paper we investigate its reliability through monte carlo simulations using calibrated business cycle models overall gali s methodology appears to be fruitful the impulse responses derived from the artificial data generally have the same sign and qualitative pattern as the true responses and the approach can be informative in discriminating between alternative models however our results reveal some important quantitative shortcomings including considerable estimation uncertainty about the impact of technology shocks on macroeconomic variables more generally the conditions under which the methodology performs well appear considerably more restrictive than implied by the key identifying assumption this underscores the importance of using economic models to guide in the implementation of the approach in interpreting the results and in assessing its limitations jel c32 e32 o33

risk premium shocks and the zero bound on nominal interest rates there appears to be a disconnect between the importance of the zero bound on nominal interest rates in the real world and predictions from quantitative dsge models recent economic events have reinforced the relevance of the zero bound for monetary policy whereas quantitative models suggest that the zero bound does not constrain optimal monetary policy

factor hoarding and the propagation of business cycles shocks this paper analyzes the role of variable capital utilization rates in propagating shocks over the business cycle to this end we formulate and estimate an equilibrium business cycle model in which cyclical capital utilization rates are viewed as a form of factor hoarding we find that variable capital utilization rates substantially magnify and propagate the impact of shocks to agents environments the strength of these propagation effects is evident in the dynamic response functions of various economy wide aggregates to shocks in agents environments in the statistics that we construct to summarize the strength of the propagation mechanisms in the model and in the volatility of exogenous technology shocks needed to explain the observed variability in aggregate u s output other authors have argued that standard real business cycle rbc models fail to account for certain features of the data because they do not embody quantitatively important propagation mechanisms these features include the observed positive serial correlation in the growth rate of output the shape of the spectrum of the growth rate of real output and the correlation between the forecastable component of real output and various other economic aggregates allowing for variable capital utilization rates substantially improves the ability of the model to account for these features of the data

investment shocks and business cycles abstract the origins of business cycles are still controversial among macroeconomists this paper contributes to this debate by studying the driving forces of fluctuations in an estimated new neoclassical synthesis model of the u s economy in this model most of the variability of output and hours at business cycle frequencies is due to shocks to the marginal efficiency of investment imperfect competition and to a lesser extent technological frictions are the key to their transmission although labor supply shocks explain a large fraction of the fluctuations in hours at very low frequencies they are irrelevant over the business cycle this finding is important because the microfoundations of these disturbances are widely regarded as unappealing

strategic perspectives of corporate sustainability management to develop a sustainable organization sustainable development refers to an economic environmental and social development that meets the needs of the present and does not prevent future generations from fulfilling their needs in this context businesses play an important role however progress towards sustainable development has been slow indicating the need for more concrete guidance that will allow businesses to act strategically and successfully in a sustainable way this theoretical paper connects three distinct but complementary dimensions of strategic management as viewed from the perspective of sustainability in order to encourage the integration of sustainability issues into corporate activities and strategies these three dimensions are strategy process strategy content and strategy context sixteen propositions related to these dimensions have been developed to explore the contributions of corporate sustainability management to the creation of value for businesses society and nature this theoretical discussion contributes to existing research in that it reveals relationships between strategic management and sustainable development and provides an agenda for further empirical research

trend breaks long run restrictions and contractionary technology improvements abstract structural vector autoregressions with long run restrictions are extraordinarily sensitive to low frequency correlations recent literature finds that the estimated effects of technology shocks are sensitive to how one treats hours per capita however after allowing for statistically and economically significant trend breaks in productivity results are much less sensitive hours fall when technology improves the issue is that the common high low high pattern of productivity growth and hours i e the low frequency correlation inevitably leads to a positive estimated response the trend breaks control for this correlation this example suggests a practical need for care in using long run restrictions

what do technology shocks tell us about the new keynesian paradigm abstract researchers have used unanticipated changes to monetary policy to identify preference and technology parameters of macroeconomic models this paper uses changes in technology to identify the same set of parameters estimates based on technology shocks differ substantially from those based on monetary policy shocks in the post world war ii united states a positive technology shock reduces inflation and increases hours worked significantly and rapidly in both cases relative to policy shock identification technology shock identification implies i long duration durability in preferences instead of short duration habit ii built in inflation inertia disappears and price flexibility increases in response to technological improvement consumption durability increases hours worked because households temporarily increase labor supply to accumulate durables towards a new higher steady state level limited nominal rigidities allow inflation to fall because firms are able to immediately cut prices when households labor supply increases finally we consider alternative data constructions and econometric specifications we find that i and or ii hold in nearly every case

identifying a permanent markup shock and its implications for macroeconomic dynamics abstract a permanent price markup shock is justified using an industry based model in which an increase in market concentration raises the desired markup moreover evidence in favor of the non stationarity of the markup is presented which in turn implies that per capita hours are also non stationary structural vector autoregressions are then constructed that can identify shocks to the markup technology and the federal funds rate the results show that 1 inflation responds immediately to shocks to the markup and technology whereas it displays a hump shaped response to a monetary policy shock and that 2 per capita hours decline in response to positive shocks to the markup and technology these empirical findings have important implications for macroeconomic dynamics including the issues on inflation inertia and the technology hours debate the paper also points out that the dynamics of the economy cannot be correctly explained without consideration of the permanent markup shock finally the approach in this paper suggests several ways to identify a wage markup shock using structural vector autoregressions

integrative re use systems as innovative business models for devising sustainable product service systems re use implies recovering items from the waste stream to use them in identical or similar processes mostly at consumer level currently re use is restricted to niches but by 2020 the european commission wants to mainstream re use as a waste management option to increase resource efficiency ecologically oriented work integration social enterprises focussing on re use re use eco wises might help accomplish as they not only intend to re integrate marginalised people into the labour market but provide comprehensive re use services e g repair and thus constitute a novel kind of sustainable product service system spss this paper contributes to a scientific framework for re use eco wises by linking existing theoretical knowledge on spss to novel knowledge from three cases representing the variety of re use eco wises in austria for analysis we use the so called business model canvas adding a comprehensive stakeholder consideration results show that re use eco wises contribute to all three dimensions of sustainability by helping reduce waste and increasing resource productivity and by providing jobs and affordable goods for disadvantaged people full implementation however will need additional efforts from all stakeholders involved including the eco wises themselves but also public authorities and society at large

sustainable development in a post brundtland world not yet two decades after the publication of our common future the world s political and environmental landscape has changed significantly nonetheless we argue that the concept and practice of sustainable development sd as guiding institutional principle as concrete policy goal and as focus of political struggle remains salient in confronting the multiple challenges of this new global order yet how sd is conceptualized and practiced hinges crucially on the willingness of scholars and practitioners to embrace a plurality of epistemological and normative perspectives on sustainability the multiple interpretations and practices associated with the evolving concept of development and efforts to open up a continuum of local to global public spaces to debate and enact a politics of sustainability embracing pluralism provides a way out of the ideological and epistemological straightjackets that deter more cohesive and politically effective interpretations of sd using pluralism as a starting point for the analysis and normative construction of sustainable development we pay particular attention to how an amalgam of ideas from recent work in ecological economics political ecology and the development as freedom literature might advance the sd debate beyond its post brundtland quagmire enhanced levels of ecological degradation vast inequalities in economic opportunities both within and across societies and a fractured set of institutional arrangements for global environmental governance all represent seemingly insurmountable obstacles to a move towards sustainability while these obstacles are significant we suggest how they might be overcome through a reinvigorated set of notions and practices associated with sustainable development one that explicitly examines the linkages between sustainability policies and sustainability politics

hours per capita and productivity evidence from correlated unobserved components models recent studies debate the effect of a permanent productivity shock on hours per capita within a structural var context this paper examines the issue using a correlated unobserved components uc framework the estimates show that permanent shocks to productivity are negatively correlated with transitory shocks to hours this result is robust for non stationary or levels stationary specifications of hours model comparisons indicate that the data do not favor imposing var type restrictions on the uc models copyright 2008 john wiley sons ltd

commodity price shocks and the business cycle structural evidence for the u s this paper evaluates the relative importance of commodity price shocks in the u s business cycle therefore we extend the standard set of business cycle shocks to include unexpected changes in commodity prices the resulting svar shows that commodity price shocks are a very important driving force of macroeconomic fluctuations second only to investment specific technology shocks particularly with respect to inflation neutral technology shocks and monetary policy shocks on the other hand seem less relevant at business cycle frequencies neutral technology shocks rather play an important role at low frequencies

the role of technology and nontechnology shocks in business cycles this article proposes a method to identify technology and nontechnology shocks that permanently affect labor productivity and applies this method to data for the g7 countries in most cases whereas technology improvements have negative or weak effects on hours worked positive permanent nontechnology shocks are expansionary permanent nontechnology shocks play an important role in business cycles particularly in the united states and japan and account for 71 of a large reduction in japan s detrended output from 1991 to 2002 credit conditions are likely to be an important driver of variations in permanent nontechnology shocks

sensitivity of impulse responses to small low frequency comovements reconciling the evidence on the effects of technology shocks this article clarifies the empirical source of the debate on the effect of technology shocks on hours worked we find that the contrasting conclusions from levels and differenced vector autoregression specifications documented in the literature can be explained by a small low frequency comovement between hours worked and productivity growth that gives rise to a discontinuity in the solution for the structural coefficients identified by long run restrictions whereas the low frequency comovement is allowed for in the levels specification it is implicitly set to 0 in the differenced vector autoregression consequently even when the root of hours is very close to 1 and the low frequency comovement is quite small removing it can give rise to biases of sufficient size to account for the empirical difference between the two specifications

the dynamic effects of neutral and investment specific technology shocks the neoclassical growth model is used to identify the short run effects of neutral technology shocks which affect the production of all goods homogeneously and investment specific shocks which affect only investment goods the real equipment price crucial for identifying the investment shocks experiences an abrupt increase in its average rate of decline in 1982 so the analysis is based on a split sample on the basis of the preferred specification the two technology shocks account for 73 percent of hours and 44 percent of output s business cycle variation before 1982 and 38 percent and 80 percent afterward the shocks also account for more than 40 percent of hours and 58 percent of output s forecast errors over a three to eight year horizon in both samples the majority of these effects are driven by the investment shocks

the evolution and main determinants of productivity in brazilian electricity distribution 1998 2005 an empirical analysis abstract this paper estimates changes in the productivity of the brazilian electricity distribution sector using data envelopment analysis dea on a panel of 18 firms from 1998 to 2005 the study decomposes the productivity change of these distribution firms in terms of technical efficiency scale efficiency and technical progress this exercise aims to help the understanding of the main determinants of the evolution of productivity focusing its relationship with the restructuring process implemented in the 1990s tfp index records a yearly positive growth rate of 1 3 in the whole period under analysis for all firms technical change was the main component behind this evolution with an average growth of 2 1 per year while technical efficiency presented a yearly negative performance of 0 8 the results prove that in general terms the incentives generated in the reform process do not seem to have led the firms to behave in a more efficient manner
