Over the past 10 years, the concepts and objectives of circular economy have been increasingly detailed and become strategic issues of international, European, and national policies. However, the transition towards circular production models continues to be affected by several barriers and critical factors that make the transition difficult to achieve. The paper tries to design a relationship between sustainable production and lean production, highlighting the opportunity to invest in reverse-logistics and how Industry 4.0 system represents a breeding ground for circular economy targets application. The aim of the current study is to examine the relationships among sustainable production, lean production, and Industry 4.0 in order to evidence the need to adopt a lean methodology and Industry 4.0 technologies in a sustainable development perspective for companies. Following a holistic vision, the authors summarize the production principles and formulas, which, although in parallel, lead to similar results and therefore represent the pillars of a competitive and sustainable business. In conclusion, exploring the circular economy principles and production chain model, challenges, opportunities, and future outlooks are formulated. 相似文献

We consider two likelihood ratio tests, the so-called maximum eigenvalue and trace tests, for the null of no cointegration when fractional cointegration is allowed under the alternative, which is a first step to generalize the so-called Johansen’s procedure to the fractional cointegration case. The standard cointegration analysis only considers the assumption that deviations from equilibrium can be integrated of order zero, which is very restrictive in many cases and may imply an important loss of power in the fractional case. We consider the alternative hypotheses with equilibrium deviations that can be mean reverting with order of integration possibly greater than zero. Moreover, the degree of fractional cointegration is not assumed to be known, and the asymptotic null distribution of both tests is found when considering an interval of possible values. The power of the proposed tests under fractional alternatives and size accuracy provided by the asymptotic distribution in finite samples are investigated. 相似文献

Most countries tax retirement savings according to the EET (exempt contributions, exempt accumulations, taxable withdrawals) regime. Relevant literature recommends the use of TEE (taxable contributions, exempt accumulations, exempt withdrawals) or EET systems and emphasizes their near equivalence. We show that this near equivalence breaks down when considering the tax effects on risk-taking. This paper proves that the TEE regime is risk-taking neutral, while the EET regime does not, in general, respect this property. The argument of risk-taking neutrality thus calls for broadening the use of the TEE configuration. 相似文献

This paper addresses issues of financial reporting within the context of European harmonization and accession. The construct of the True and Fair View (hereafter TFV) constitutes a locus of reflection for the establishment of a mutually intelligible foundation for financial reporting in the New Europe including applicant states for European Union (hereafter EU) membership. This paper provides insights as to the meaning and the local embeddedness of TFV in the context of the Polish transitional economy. The Audit Act 1994 and the Accounting Act 1994, as amended by the 2000 Acts, incorporate the provisions of European law with the aim of harmonizing Polish accounting and financial reporting regulations with the corresponding regulations in the EU. The Accounting Act 1994 for the first time introduced in Poland the current wording of the TFV construct in accordance with the requirements of the Fourth Directive. The question addressed in this paper is how the construct of TFV is understood and operationalized. This paper demonstrates the particular local understanding of the TFV construct in contemporary Poland through (1) textual analysis of the legal pronouncements (both national and international) and (2) narrative analysis of local debates and commentaries in the national press and academic journals. Given the difficulty of expressing judgements based upon accumulated experience, where much of the experience is constituted by continental influence, in particular the German tradition, and regulatory arrangements of a centrally planned economy, Polish practice perceives the TFV requirement primarily as a formal and legal compliance, and not yet as something with a substantial rationale in the observance of the rule of accounting law. The paper concludes that TFV is a contingent construct which resides in a particular socio-economic, historic and cultural context and is understood differently outside this context. The local Polish reception and understanding is articulated. 相似文献

The aim of this paper is to contribute to the debate on constitutional rules and their economic effects by extending focus to the de jure–de facto constitutional gap. First, evidence is provided that size of this gap matters as higher gaps lower the effectiveness of the constitutional commitment mechanism. Second, several explanations of this gap are identified, in particular relating to the democratization process, political conflict, age and comprehensiveness of the constitution. The conclusions are based on an empirical study for the unique setting of the post-socialist countries of Europe and Asia, which all enacted new constitutional frameworks after 1989 and it is shown that in some of these countries constitutions acted as blueprints. 相似文献

This paper develops a new methodology of spatial econometric modelling for regional public investment in local economies. The approach, based on the financial concept of net present value of cash flows, can be applied in the analysis of regional public investment with long-term financial inputs and outputs. With local public revenues related to spending in the model, one can observe economies of scale of investment with possible saturation effects and a marginal investment multiplier, explaining the extent to which public investment costs translate into public revenues. The main advantage of the proposed model is to behave counter-cyclically due to accumulation over the periods and to cover multi-period investments as well as postponed effects. This paper gives an example of public investment efficiency in Polish NUTS-5 municipalities regions. 相似文献

This study explores the effects of the European Union accession announcement on the valuations of companies in the prospective member states. I examine firm level data from ten countries which joined the EU in May 2004. My analysis reveals that the announcement of these countries’ future EU membership in November 2001 significantly increased the Tobin’s Q ratios of their publicly traded firms several years before formal membership was granted. This increase in firm value can likely be attributed to a reduced cost of capital and/or an expected increase in growth opportunities and cash flows, resulting from the announcement of their countries’ inclusion in the EU. 相似文献

The most flamboyant economic effect of the euro changeover on consumers was a dramatic increase in perceived inflation. To
directly measure perceived inflation, Brachinger developed a new index of perceived inflation (IPI). This index is based on
some hypotheses about factors influencing perceived inflation. An experimental study is presented which investigated the influence
of two of these hypothesized factors, purchase frequency and loss aversion, on individual judgments of price changes. Furthermore,
two additional factors have been included that are informative with respect to the IPI, product segment and price level. Judgments
of inflation were assessed with three methods, yielding different results. Empirical evidence for the hypotheses was obtained.

The current energy portfolio of the United States is exposed to significant risk, which depends on the price volatility of
the energy sources. This paper focuses on the composition of energy portfolios for the energy sector of the United States
and possible solutions to optimize this investment. The study utilizes the modern portfolio theory mean-variance approach,
a risk-return analysis, to compose the efficient frontier of portfolios in which the risk is minimized for a given return.
The performance of each energy portfolio, consisting of oil, coal, natural gas, nuclear energy, and renewable energy, is measured
using the Sharpe Ratio and compared to the existing portfolio. Using future prices of fuels and accounting for external costs,
the study provides further evidence that the current energy portfolio of the United States is not efficient. In addition,
the study shows how including the cost of pollution, measured by the intensity of carbon emissions, changes the energy source
allocation within the portfolio by including less carbon-intensive substances. The study implies that further diversification
of the energy sector by including investment in hydroelectric energy generation technologies may decrease our dependence on
more volatile sources of energy and consequently reduce the possibility of energy supply interruption from commodity price
volatility. This proposes that the government focus on implementing a strategy to facilitate the introduction of renewable
energy into our energy portfolio. The shift away from an infrastructure heavily dependent on fossil fuels towards one with
more investment in renewable energy can be achieved by granting subsidies for renewable energy technologies and by implementing
appropriate emissions prices to account for external energy generation costs. 相似文献
