The Integrated Pollution and Prevention Control (IPPC) directive from the European Union implies that regulatory emission caps shall be set in accordance with each industry’s Best Available Techniques (BAT). The directive, which represents a harmonization of environmental regulations towards a BAT principle, is currently being implemented in all the EU member states and the states associated with the European Economic Area. The aim of this paper is to examine the effect of this implementation on emission reductions and costs, using data from Norwegian manufacturing industries. Data Envelopment Analysis (DEA) is used to construct a frontier of all efficient installations. The frontier is based on all installations within an industry that use the Best Practice Technique (BPT). We estimate the changes in emissions due to the implementation of IPPC as the difference between an installation’s actual emissions and the emissions that would occur if it operated on the frontier. The method reveals a strong potential for emission reductions. Further, estimates of short-run abatement costs indicate that considerable emission reductions can be achieved with low or no costs, but that the implementation of a strict BAT principle for all installations involves substantial costs. To the extent that the abatement costs of an installation would be excessive, IPPC includes some limited modifications of the strict BAT principle. It seems important that these modifications are fully utilized by authorities to achieve the most cost efficient implementation of the directive.   相似文献

Exploiting new resource “frontiers,” such as agricultural land and mineral reserves, is a fundamental feature of economic development in poor economies. Yet frontier-based development is symptomatic of a pattern of economy-wide resource exploitation in developing economies that: (a) generates little additional economic rents, and (b) what rents are generated are not being reinvested in other sectors. Such development is inherently unsustainable. The following paper explains this phenomenon, and provides evidence that long-run expansion of agricultural land and oil and natural gas proved reserves across poor economies is associated with lower levels of real income per capita. The paper proposes a frontier expansion hypothesis to explain why the structural economic dependence of these economies on frontier land expansion and resource exploitation is not conducive to sustained long-run growth. The key to sustainable economic development in poor economies will be improving the economic integration between frontier and other sectors of the economy, targeting policies to improved resource management in frontier areas and overcoming problems of corruption and rent-seeking in resource sectors.   相似文献

The Wire (five seasons, 2002–2008) takes place in Baltimore, an urban venue that is distinguished by diverse modes of violence and alienation – the colour line, tensions between governmental bureaucracy and citizen, between policing executives and investigators, between corporate-oriented drug dealers and individual (take-no-prisoners) dealers, and in general between aspiring change-agents and entrenched power holders. And most significantly for this analysis, The Wire explores what Robert Crooks identifies as the new “urban frontier.” The older frontier (in “the West”) is depicted in Deadwood (three seasons, 2004–2006). That frontier, as Cronon, Miles, and Gitlin point out, was, at the outset of the Euro American–Native American encounter, a space of negotiation, a space in which institutionalised regionalisation had not yet been installed.  相似文献

We employ cooperative bargaining theory and Nash’s ‘rational threats’ idea to cast light on the biodiversity bargaining problem. The problem of global environmental negotiations is argued to be of the nature of a bargaining problem, in which bargainers must agree on the distribution of cooperative surplus in order to move to the bargaining frontier. We discuss the importance of both efficiency (bargaining frontier) and fairness (recognition of characteristics of bargainers) in the choice of the appropriate contract. We show that the incremental cost contract, used to resolve the biodiversity bargaining problem, is of the form of an extreme point contract that fails to recognise the contributions of the South to the production of cooperative surplus. A rational response to such a contract is the use of threats of biodiversity destruction. Contracts must evince both efficiency and fairness in order to represent lasting solutions.  相似文献

The main objective of this article is to analyse labour productivity growth and convergence in the Spanish regions between 1965 and 1995, decomposing total factor productivity gains into technological progress and efficiency change by means of Malmquist productivity indices. On the basis of this decomposition, labour productivity growth is broken down into components attributable to technological change (shifts in the frontier), efficiency gains (movements toward the frontier) and capital accumulation (movements along the frontier). The approach followed in this study is based on work initiated by Färe et al., where a link between the economic growth and convergence literature and the production frontier approach was established. Furthermore, in the spirit of Quah's approach, the evolution of the whole distribution is considered. Thus, the analysis of the dynamics of the entire distribution of labour productivity and the factors behind it – technological progress, efficiency gains and capital accumulation – combine both approaches, yielding new insights into the process of productivity growth and convergence experienced by the Spanish regions over the last 30 years.  相似文献

In this paper, we explore whether higher corporate tax rates, because they lower the after‐tax returns to productivity‐enhancing investments, reduce the speed with which small firms converge to the productivity frontier. Using data for 11 European countries, we find evidence that their productivity catch‐up is slower when the statutory corporate tax rates are higher. In contrast, we find that large firms are instead affected by effective marginal rates. Using the reduced‐form model of productivity convergence of Griffith et al . (2009, Journal of Regional Science 49 , 689–720), our results are robust to a host of robustness checks and a natural experiment that exploits the 2001 German tax reforms.  相似文献

The Role of Natural Resources in Economic Development   总被引:2,自引:0,他引:2  
Economists now recognize that, along with physical and human capital, environmental resources should be viewed as important economic assets, which can be called natural capital. Three recent debates have emerged over the role of natural capital in economic development. First, as many ecological services are unique, does the environment have an “essential” role in sustaining human welfare, and if so, are special “compensation rules” required to ensure that future welfare is not worsened by natural capital depletion today? Second, the environmental Kuznets curve (EKC) hypothesis has fostered empirical estimations of an “inverted U” shaped relationship between a variety of indicators of environmental pollution or resource depletion and the level of per capita income. Does the existence of such EKC relationships suggest that environmental degradation will eventually decline with growth? Finally, recent economic theories and empirical evidence have questioned whether lower income economies that are endowed with abundant natural resources develop more rapidly than economies that are relatively resource poor. Is it possible that resource abundant economies are not reinvesting the rents generated from natural resource exploitation into productive assets, or that resource booms actually divert economic resources from more productive and innovative sectors?  相似文献

We present results on undiscounted optimal policies in the Leontief two‐sector growth model with durable capital. Unlike the results with a labour intensive consumption goods sector, we show that a monotonic optimal programme is only one special case out of many richer possibilities of transition dynamics. Depending on the initial capital stock, and a key parameter ζ that could be interpreted as a marginal rate of transformation of capital between today and tomorrow, an optimal programme may converge to a period‐two cycle; and even when it converges to the golden rule stock, it can do so (damped) cyclically or with a “jump”.  相似文献

In repeated normal‐form (simultaneous‐move) games, simple penal codes (Abreu, Journal of Economic Theory 39(1) (1986), 191–225; and Econometrica 56(2) (1988), 383–96) permit an elegant characterization of the set of subgame‐perfect outcomes. We show that in repeated extensive‐form games such a characterization no longer obtains. By means of examples, we identify two types of settings in which a subgame‐perfect outcome may be supported only by a profile with the property that the continuation play after a deviation is tailored not only to the identity of the deviator but also to the nature of the deviation.  相似文献

ABSTRACT

Despite the truism that less is known about the deep-sea than outer space, deep-sea mining (DSM) is being promoted as the next frontier of resource extraction. In 2019, Nautilus Minerals hopes to become the world’s first company to mine the deep seabed in the waters off Papua New Guinea (PNG). DSM thus stands at the threshold of becoming a matter of politics; it has provoked a wide range of geopolitical imaginaries variously relating to ‘resource security’ and ‘progress’, on the one hand, and environmental disaster and precaution on the other. However, these accounts do little to address the specific ‘nature’ of the deep-sea, seabed and their extreme location and materialities, and are instead framed by classic geopolitical concerns with interstate relations. Against this background and illustrated by examples centred on PNG, this paper argues that future engagements with the geopolitics of DSM are more accurately conceptualised by an engagement with time as well as three dimensional space. This includes the multiple spatial and temporal registers through which both the geology and ecologies of seabed and seawater operate. By highlighting the importance of resource temporalities, it suggests that the geopolitics of both DSM and extraction in extreme places more generally is not only spatially complex, it is also a matter of time.  相似文献

Growing environmental concerns, emerging economies, and the strong uncertainties about future prices of fossil fuels as well as about CO2 emissions contribute to a potential renaissance for biorefining industries. According to theories on technology shifts and innovations (e.g. [Utterback, J. M. 1994. Mastering the dynamics of innovation. How companies can seize opportunities under technological change. Harvard Business School Press]), heavy process industries like pulp and paper tend to be rigid towards disruptive innovations and instead focus on incremental innovations and economies of scale. However, a major empirical contribution from this case study demonstrates that some incumbents may escape the lock-in and form a new biomass development block. The study also contributes to academic as well as technology and innovation management perspectives in process-based and natural resource-based industries, where process innovations are tightly coupled with product innovations in inter-industry (vertical) linkages, the so-called development block.  相似文献

In a cross section of OECD countries, we replace the macroeconomic production function by a production possibility frontier, total factor productivity being the composite effect of efficiency scores and possibility frontier changes. We consider, for the periods 1970, 1980, 1990 and 2000 one output – GDP per worker – and three inputs – human capital, public physical capital per worker and private physical capital per worker. We use a semi-parametric analysis, computing Malmquist productivity indexes, and we also resort to stochastic frontier analysis. Results show that private capital is important for growth, although public and human capital also contribute positively. A governance indicator, a nondiscretionary input, explains inefficiency. Better governance helps countries to achieve a better performance. Nonparametric and parametric results coincide rather closely on the movements of the countries vis-à-vis the possibility frontier and on their relative distances to the frontier.  相似文献

This paper estimates and compares the cost efficiency of the Chinese banking industry among different ownership types for the period 2003–2014, using the stochastic metafrontier model. We find that foreign banks have the lowest cost frontier, while state‐owned commercial banks undertake the least sophisticated technology. Moreover, the results of the upward trend in the technology gap ratio (TGR) and in metafrontier cost efficiency support that a more open financial market is able to enhance banking efficiency. As for the role of environmental conditions, off‐balance sheet items, non‐performing loans, and financial market structure significantly impact the TGRs of different bank types.

This paper examines the standard symmetric two‐period R&D model with a deterministic one‐way spillover structure: know‐how flows only from the high R&D firm to the low R&D firm (but not vice versa). Though firms are ex ante identical, one obtains a unique asymmetric equilibrium (pair) in R&D investments, leading to interfirm heterogeneity in the industry. R&D cooperation by means of a joint lab is considered and compared to the non cooperative solution. The main part of the paper provides a second‐best welfare analysis in which we show that the joint lab yields a socially optimal R&D level subject to an equal treatment (of firms) constraint, which also coincides with the noncooperative solution in the absence of spillovers. We also investigate the welfare costs of this equal treatment constraint and find that they can be quite significant.  相似文献

Conditions for Sustainable Optimal Economic Development   总被引:2,自引:0,他引:2  
This paper shows that, for dynamic optimizing economies with different types of natural resource, environmental, and human‐made capital stocks, a necessary and sufficient condition for permanently sustaining an optimal utility/consumption level is the stationarity of the current‐value Hamiltonian. For economies whose development is not exogenously and directly affected by time (i.e., time‐autonomous economies), this stationarity condition generalizes Dixit et al.’s (1980 ) “zero‐net‐aggregate‐investment” rule of sustain‐ability, which in turn generalizes Solow‐Hartwick’s sustainability rule. For non‐autonomous economies, the stationarity condition is not generally fulfilled, and the current‐value Hamiltonian under (over) estimates the true welfare level by an amount equal to the discounted value of the net “pure time effect.” For the non‐autonomous case of a time‐dependent utility discount rate, a general condition on the discount rate function (of which the hyperbolic discount rate function is a special case) upholds the results obtained for autonomous cases. The paper concludes with a discussion of policies that promote both optimality and sustainability objectives.  相似文献

In the 1960s Shapley provided an example of a two-player fictitious game with periodic behaviour. In this game, player A aims to copy B's behaviour and player B aims to play one ahead of player A. In this paper we generalise Shapley's example by introducing an external parameter. We show that the periodic behaviour in Shapley's example at some critical parameter value disintegrates into unpredictable (chaotic) behaviour, with players dithering a huge number of times between different strategies. At a further critical parameter the dynamics becomes periodic again, but now both players aim to play one ahead of the other. In this paper we adopt a geometric (dynamical systems) approach. Here we prove rigorous results on continuity of the dynamics and on the periodic behaviour, while in the sequel to this paper we shall describe the chaotic behaviour.  相似文献

Abstract

Objective:

The aim of this study was to assess the cost-utility and value of reducing the uncertainty associated with the decision to use first-line biologic treatment (bDMARD) after the failure of one or more traditional drugs (tDMARD) in moderate-to-severe rheumatoid arthritis (msRA) in Finland.

Research design and methods:

The treatment sequences were compared among 3000 hypothetical Finnish msRA patients using a probabilistic microsimulation model in a lifetime scenario. Adalimumab?+?methotrexate, etanercept?+?methotrexate, or tocilizumab?+?methotrexate were used as first biologics followed by rituximab?+?methotrexate and infliximab?+?methotrexate. Best supportive care (BSC), including tDMARDs, was assumed to be used after the exhaustion of the biologics. Methotrexate alone was added as a further comparator. Efficacy was based on ACR responses that were obtained from a mixed treatment comparison. The resources were valued with Finnish unit costs (year 2010) from the healthcare payer perspective. Additional analyses were carried out, including productivity losses. The Health Assessment Questionnaire (HAQ) values were mapped to the EQ-5D values using the tocilizumab trials; 3% annual discounting for costs and quality-adjusted life years (QALY) and extensive sensitivity analyses were completed.

Main outcome measures:

Incremental cost per QALY gained and multinomial expected value of perfect information (mEVPI).

Results:

bDMARDs significantly increase the QALYs gained when compared to methotrexate alone. Tocilizumab?+?methotrexate was more cost-effective than adalimumab?+?methotrexate or etanercept?+?methotrexate in comparison with methotrexate alone, and adalimumab?+?methotrexate was dominated by etanercept?+?methotraxate. A QALY gained with retail-priced (wholesale-priced) tocilizumab?+?methotrexate costs €18,957 (€17,057) compared to methotrexate alone. According to the cost-effectiveness efficiency frontier and cost-effectiveness acceptability frontier (CEAF), tocilizumab?+?methotrexate should be considered before rituximab?+?methotrexate, infliximab?+?methotrexate, and BSC. Based on the CEAF, tocilizumab?+?methotrexate had a 60–93% probability of being cost-effective with €20,000 per QALY gained (mEVPI €230–2182).

Conclusions:

Tocilizumab?+?methotrexate is a potentially cost-effective bDMARD treatment for msRA, indicating a low value of additional research information with the international threshold values.

Limitations:

Efficacy based on an indirect comparison (certolizumab pegol, golimumab excluded), fixed treatment sequence after the exhaustion of first bDMARD, Swedish resource use data according to HAQ scores, and inpatient costs assumed to include surgery.  相似文献

This article empirically estimates the firm-specific productive capacity realization (PCR) indices using the stochastic frontier production function and analyses a number of variables explaining realization rates across firms and over time. Following Battese and Coelli (1995 Battese, GE and Coelli, TJ. 1995. A model for technical inefficiency effects in a stochastic frontier production function for panel data. Empirical Economics, 20: 32532. [Crossref] [Google Scholar]) the stochastic frontier production function is used to estimate capacity output and thereby PCR. Using the Firm level panel data from Bangladesh food manufacturing, the results show that capacity realization rates widely vary across firms and over time. The average rate of realization is about 65% implying that most of the firms are producing away from their full production capacity. This article also identifies several firm-specific and policy-related variables explaining capacity realization. The results show that firm size (SZE) and outward orientation (OPN) have positive while capital intensity (CNSTY), market structure (MSTRE) and effective rate of assistance (ERA) have negative impact on realization rates. Strikingly, both policy-related variables are statistically insignificant. Sensitivity analysis using the ‘extreme bound analysis’ also confirms the fragility (insignificance) of these two variables. Excessive support to firms and piecemeal liberalization reform may be attributed to these results. Thus, further reform of the domestic and trade policies are suggested to ensure competition and competitiveness of the manufacturing sector and of the country.  相似文献

This paper studies the nonlinear adjustment between industrial production and carbon prices – coined as ‘the carbon-macroeconomy relationship’ – in the EU 27. We model carbon price returns and industrial production as nonlinear and state-dependent, with dynamics depending on the sign and magnitude of past realization of returns and the growth of industrial production. Our findings show that (i) macroeconomic activity is likely to affect carbon prices with a lag, due to the specific institutional constraints of this environmental market; (ii) the joint dynamics of industrial production and carbon prices seem adequately captured by two-regime threshold vector error-correction and two-regime Markov-switching VAR models compared to linear models as main competitors. The regime-switching models proposed are profoundly checked for their economic content and statistical congruency, and are found to provide a sound statistical framework for a comprehensive analysis of the carbon-macroeconomy relationship.  相似文献

We offer a novel investigation of the effect of environmental risk on cooperation in the Voluntary Contribution Mechanism. Our baseline is the standard setting, in which the personal return from the public good is deterministic, homogeneous, and publicly known. Our experimental treatments alter this classic design by making the marginal per capita return from the public good probabilistic. In the homogeneous risk (HomR) treatment, the random draw is made for the whole group, whereas in the heterogeneous risk (HetR) treatment, this happens independently for each group member. Our hypothesis is that different environmental risks may differently affect the ex post payoff inequalities, so that other‐regarding preferences (inequality aversion) may generate higher contributions in HomR than in HetR. Our main result is that the environmental risk does not affect the patterns of cooperation either in the one‐shot or in the finitely repeated version of the game. This suggests that the standard experimental methodology provides a robust and conservative measure of human cooperation.  相似文献
