On the Second-best Policy of Household's Waste Recycling

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.     

合同诈骗罪的“非法占有”的解释和认定

Illegal Landings: An Aggregate Catch Self-Reporting Mechanism

To solve the problem of illegal landings this article proposes a new tax mechanism based on the regulator's own aggregate catch estimates and ex ante self-reports of planned catch by fishermen. We show that the mechanism avoids illegal landings while ensuring (nearly) optimal exploitation and generating (nearly) correct entry and exit incentives. Finally we simulate the mechanism for the Danish cod fishery in Kattegat to obtain a rough indicator of the size of the tax. It turns out that the average tax payment as a percentage of profit is surprisingly low.     

高校发生违法违纪案件的特点、原因及其防范措施

近几年,高校在改革中取得了很大的成绩,但在改革中也发生了许多违法违纪案件,这些案件特点是:经济类案件违纪金额越来越大;发案部位不断增加;带有行业特点的违纪案件占有相当比例.主要原因是多方面的,有客观原因,也有主观原因.对违法违纪案件我们应采取四方面的防范措施:加强廉政教育、抓好制度建设、强化依法监督、依法加大办案力度,这样才会使高校改革逐渐步入完善,并在改革中有更新的发展空间.     

The Federal Reserve's Tools for Policy Normalization in a Preferred Habitat Model of Financial Markets

We develop a model to analyze monetary policy implementation with multiple Federal Reserve liabilities and superabundant reserves. The analysis demonstrates the Federal Reserve's tools including interest on excess reserves (IOER), overnight reverse repurchase agreements (ON RRP), and term deposits should allow the Federal Reserve to raise the short‐term interest rates to any desired level. We find the contribution of each the increase in the IOER and ON RRP offering rates in firming money market rates suggested by the data during the December 2015 policy tightening event is remarkably similar to the effect of each tool implied by the calibrated model.

How are young music artists configuring their media and sales platforms in the digital age?

Abstract

Research on how music artists generate sales from their content through different platforms is scant. In this study, configuration theory is used to show that different market access configurations are viable simultaneously and that young musicians differ significantly in how they generate revenues. Using data on the media and sales performance of 338 young musicians in the Netherlands, we show that there is an ‘Emerging Star’ group (7–13% of artists depending on regional scope) and that record labels play an important role in this configuration providing broad media access on all platforms, both old and new. Digital age ‘Independents’ (14% of young artists), mostly without a record label, seem to benefit from the use of social media while exploiting synergies around live music. All artists in the remaining groups ‘Question Marks’ and ‘Hobbyists’ experience low to very low performance on all platforms. This study shows that configuration theory can provide detailed insight into viable and unviable marketing strategies. In particular, it shows that the globally declining music CD platform can still be very important for specific artists that exploit synergies between live performances, on-site CD sales and social media fan relationship management. The implications for marketing theory and young music artists are discussed.

操作目标利率的选择与传导 ——基于MLF利率与隔夜利率的实证检验

依据2014-2018年月度数据,运用VAR模型考量MLF利率与隔夜利率对贷款加权利率、商业银行行为以及金融市场利率与金融市场波动的影响.结果表明:MLF利率对贷款加权利率和商业银行行为的影响较大,隔夜利率对金融市场利率和金融市场波动的影响较大.鉴此,应利用MLF利率调节贷款加权利率与商业银行行为,利用隔夜利率调节金融市场利率与金融市场波动,当两种利率的调节效果收敛接近时,再最终确定唯一的操作目标利率.
