On the Second-best Policy of Household's Waste Recycling   总被引:5,自引:1,他引:5  
This study analyzes the second-best household's waste recycling policy. If we assume the first-best economy with no illegal disposal or transaction costs, then unit pricing, an advance disposal fee and a recycling subsidy are required in order to achieve the social optimum such that both the sum of unit pricing and an advance disposal fee and the sum of unit pricing and a recycling subsidy are equal to the marginal disposal cost. Furthermore, the first-best outcome can also be obtained by a producer take-back requirement system.In the real economy, however, various factors prevent the first-best optimal outcome. In this study we consider two factors, one being the transaction cost associated with a recycling subsidy (or refund) and the other being illegal disposal by the consumer. If a recycling subsidy (or a deposit-refund system) is adopted, a transaction cost associated with it will be generated. Alternatively, if unit pricing is adopted, some of the consumed goods may be disposed of illegally. We show the complete trade-off between unit pricing and a recycling subsidy. In other words, we can not adopt unit pricing and a recycling subsidy simultaneously. As a result, there are three candidates for the second-best policy: unit pricing with an advance disposal fee, a deposit-refund system, and a producer take-back requirement system.Which of these three policies is the second-best policy will depend on the relative magnitude of the price of a recycled good and the marginal transaction cost associated with a recycling subsidy (or the refund in a deposit-refund system). Generally, if the price of a recycled good is positive and the marginal transaction cost is relatively high, unit pricing with an advance disposal fee is the second-best policy. However, where the price of a recycled good is negative and the marginal transaction cost is relatively high, a producer take-back requirement system is the second-best policy. Further, where the marginal transaction cost is relatively low, a deposit-refund system is the second-best policy, regardless of whether the price of a recycled good is positive or negative.  相似文献

This paper analyses the development of biotechnology clusters in North Carolina (NC) and Israel. In both NC and Israel, when the biotechnology was identified as a potential strategic priority, the framework conditions were suitable for successful policy-targeting. NC presents a case of a successful transition from a traditional manufacturing economy to a knowledge economy. The most successful part of this transition was a policy-led development of a biotechnology cluster in the Research Triangle. While Israel also presents a case of a successful transition from a low-tech economy to a knowledge-intensive economy, Israel failed to develop a successful biotechnology cluster. We suggest that this failure is mostly due to a failure to implement policy to encourage such development. We argue that the elements, which separate NC's success from Israel's failure, are: a clear vision and strategic planning; timely response, long-term commitment; strong leadership; cooperation between the government, private sector and academia, and an adjustable policy-making process.  相似文献

In this paper, we examine which auction format, first-price or second-price, a seller will choose when he can profitably cheat in a second price auction by observing all bids by possible buyers and submitting a shill bid as pretending to be a buyer. We model this choice of auction format in seller cheating as a signaling game in which the buyers may regard the selection of a second price auction by the seller as a signal that he is a shill bidder. By introducing trembling-hand perfectness as a refinement of signaling equilibrium, we find two possible strictly perfect signaling equilibria. One is a separating equilibrium in which a noncheating honest seller selects a first price auction and a cheating seller does a second price auction. In another pooling equilibrium, however, both cheating and non-cheating sellers select a second price auction. The conclusion that a seller chooses a second price auction even if he cannot cheat is in contrast to the previous literature, which focused on the case of independent values. We thank an anonymous referee for useful comments that have improved the paper.

Drawing on the institutionalist approach to a capitalist economy as a money economy, I regard financial regulation and supervision as a collective action problem. I argue that, given the basic characteristics of such an economy, a financial system may be considered as a public utility and financial stability as a public good. I then maintain that the provision of the latter could not rely on private market mechanisms, such as self-regulation and price-directed incentives. As capitalism develops through more financialized forms, new institutions and regulatory rules must be designed to reframe the market’s boundaries in order to consolidate systemic stability, which is a basic condition for continuous and sustainable economic relations in society. I then suggest a precautionary-principle-based macro-prudential approach to financial regulation in order to ensure a sustainable provision of finance and financial stability that is consistent with the characteristics of a money economy.  相似文献

This article defends the proposal of sustainable degrowth. A starting premise is that resource and CO2 limits render further growth of the economy unsustainable. If degrowth is inevitable, the question is how it can become socially sustainable, i.e. a prosperous and stable, rather than a catastrophic, descent. Pricing mechanisms alone are unlikely to secure smooth adaptation; a full ensemble of environmental and redistributive policies is required, including - among others - policies for a basic income, reduction of working hours, environmental and consumption taxes and controls on advertising. Policies like these, that threaten to “harm” the economy, are less and less likely to be implemented within existing market economies, whose basic institutions (financial, property, political, and redistributive) depend on and mandate continuous economic growth. An intertwined cultural and political change is needed that will embrace degrowth as a positive social development and reform those institutions that make growth an imperative. Sustainable degrowth is therefore not just a structuring concept; it is a radical political project that offers a new story and a rallying slogan for a social coalition built around the aspiration to construct a society that lives better with less.  相似文献

Individuals who compete in a contest-like situation (for example, in sports, in promotion tournaments, or in an appointment contest) may have an incentive to illegally utilize resources in order to improve their relative positions. We analyze such doping or cheating within a tournament game between two heterogeneous players. Besides the direct and indirect costs of doping, three major effects are identified which determine a player's decision to deviate from a no-doping situation — a cost effect, a likelihood effect and a base-salary effect. Moreover, the influence of heterogeneity and exogenous performance risk on a no-doping outcome, and the influence of ex-ante and ex-post doping tests on the players' investments are discussed.  相似文献

In the U.S., virtually no new coal-fired power plants have been built in recent years. Both industry experts and academics seem to believe that no rational firm will build a new coal-fired plant. Will such a trend continue in the future? To provide insights into this question, we investigate the optimal decision of an electricity company with an irreversible and deferrable opportunity to build either a new coal-fired or natural gas-fired power plant as its new base-load resource. According to our real option analysis, the optimal decision depends on the location. In the case of the eastern U.S., it is optimal to choose a natural gas plant if a firm is given a choice among a new natural gas plant, a new coal plant and deferring the investment. However, contrary to the common sentiment in the industry and academia, building a new coal plant in the western U.S. is still more economical than building a new natural gas plant in the absence of emission pricing. Furthermore, introducing carbon pricing to western U.S. states, as California did, can substantially increase the probability that a firm will optimally choose a natural gas plant over a coal plant.  相似文献

知识是一种独特的有价值的关键资源,对知识的管理和有效利用对于增强组织核心竞争力有着至关重要的作用。但组织内知识流动并非易事,知识共享通常不是自然发生的。组织中员工知识共享水平的提高,需要员工之间进行沟通与交流,社会化为员工沟通交流提供了机会。非正式社会化作为发生在个人层面的社会化类型,对组织中人与人之间的知识共享行为具有非常重要的作用。对来自长江三角洲的13家企业问卷调查数据进行分析,搭建非正式社会化、社会交互作用、权力距离、知识共享4个变量之间的交互作用模型,采用探索性因子分析、验证性因子分析和结构方程分析方法,就非正式社会化对知识共享的影响机制进行了讨论。  相似文献

A dataset is a list of observed factor inputs and prices for a technology; profits and production levels are unobserved. We obtain necessary and sufficient conditions for a dataset to be consistent with profit maximization under a monotone and concave revenue based on the notion of cyclic monotonicity. Our result implies that monotonicity and concavity cannot be tested, and that one cannot decide if a firm is competitive based on factor demands. We also introduce a condition, cyclic supermodularity, which is both necessary and sufficient for data to be consistent with a supermodular technology. Cyclic supermodularity provides a test for complementarity of production factors. We are very grateful to two anonymous referees for suggestions, comments, and corrections. We also thank Kim Border for his suggestions on an earlier draft.  相似文献

The prevailing models explaining how technologies develop along a specific trajectory largely focus on the circumstances that lead to technological lock-in. We contribute substantially to this area of research by investigating the circumstances under which technological development may break-out of a trajectory. We argue that for this to happen, a third selection mechanism—beyond those of the market and of technology—needs to upset the lock-in. We model the interaction, or mutual shaping among three selection mechanisms, and thus this paper also allows for a better understanding of when a technology will lock-in into a trajectory, when a technology may break-out of a lock-in, and when competing technologies may co-exist in a balance. As a system is conceptualized to gain a (third) degree of freedom, the possibility of bifurcation is introduced into the model. The equations, in which interactions between competition and selection mechanisms can be modeled, allow one to specify conditions for lock-in, competitive balance, and break-out.  相似文献

Managing the introduction of nonindigenous species is becoming a major goal of policy-makers at regional, national and international scales. Here we investigate, at the national level, the ideal design and expected net benefits of a risk assessment program for evaluating the desirability of nonindigenous species imports. We show how to enhance the statistical rigor of such a system by correcting a common non-random sampling problem encountered in the data. This correction enables model output to be interpreted in an economically relevant way and facilitates a theoretically rigorous characterization of the balance between trade and nonindigenous species establishment risk. Using reptiles and amphibians imported to the U.S. as a case study, we characterize economic outcomes over a range of cases and demonstrate substantial expected returns to such a screening program, relative to the current effectively open-door policy. Our results are informative for the current debate in the U.S. about whether to require federal agencies to apply risk assessment before allowing a species for import. The framework presented decomposes a complex argument about risk management into component economic and statistical parts, allowing for debate and improved understanding over each element to inform the overall program in a transparent fashion.  相似文献

The authors describe an innovative active learning strategy for a course on the economics of developing countries—a project designing a small-scale economic development project. Student teams research issues faced by developing countries and identify a specific problem in a specific locale. Students then create a detailed, feasible plan to alleviate the problem. Student plans include five key components: justification, implementation, budget, funding and evaluation. After having implemented this project for six years, the authors believe it has the potential to enhance learning and improve analytical, creative problem-solving and research skills. Results from a spring 2017 survey, where students respond favorably to the project, are discussed.  相似文献

Research on tipping has been limited to restaurants, tourism and taxis. This study investigates the economic and demographic factors that influence whether a person tips and the amount tipped for a haircut in a beauty salon. Using a two-step model, it is found that both economic and demographic factors influence tipping behaviour. A person is more likely to tip if he/she has long hair, attends to grooming on a frequent basis, has a lower income, and is male. Price, gender, age, and the use of appointments are factors that influence the amount that one tips.  相似文献

This paper investigates the causes behind the Euroland crisis, particularly Germany’s role in it. It is argued that the crisis is not primarily a ‘sovereign debt crisis’, but rather a (twin) banking and balance of payments crisis. Intra-area competitiveness and current account imbalances, and the corresponding debt flows that such imbalances give rise to, are at the heart of the matter, and they ultimately go back to competitive wage restraint on Germany’s part since the late 1990s. Germany broke the golden rule of a monetary union: commitment to a common inflation rate. As a result, the country faces a trilemma of its own making and must make a critical choice, since it cannot have it all – perpetual export surpluses, a no transfer/no bailout monetary union, and a ‘clean,’ independent central bank. Misdiagnosis and the wrongly prescribed medication of austerity have made the situation worse by adding a growth crisis to the potpourri of internal stresses that threaten the euro’s survival. The crisis in Euroland poses a global ‘too big to fail’ threat, and presents a moral hazard of perhaps unprecedented scale to the global community.  相似文献

In an information economy, the effective management of a massive amount of technological information is inevitable when attempting to facilitate the decision-making process. It is an important part of selecting R&D projects and allocating budgets to promising technology development. Information visualisation is thus regarded as a critical tool in technological information management because it can provide decisive implications that the intelligence of humans cannot produce. This paper proposes six graphical forms, including a technology tree, a technology map, a technology network, a technology matrix, a technology curve, and a technology dictionary, presenting the generic form and concept of each method. Moreover, the principles and applications of such visualisation tools are suggested in order to enhance their use in practical circumstances. A case study of TFT-LCD (thin film transistor-liquid crystal display) technology will help to explain how to apply visualisation tools to strategic technology management.  相似文献

We compute average markups as a measure of market power throughout time and study their interaction with fiscal policy and macroeconomic variables in a VAR framework. From impulse-response functions, the results, with annual data for a set of 14 OECD countries, show that the markup (i) depicts a pro-cyclical behaviour with productivity shocks and (ii) a counter-cyclical behaviour with fiscal spending shocks. We also use a PVAR, increasing the efficiency in the estimations, which confirms the country-specific results.  相似文献
