Online portfolio selection (PS) has been extensively studied in artificial intelligence and machine learning communities in recent years. An important practical issue of online PS is transaction cost, which is unavoidable and nontrivial in real financial trading markets. Most existing strategies, such as universal portfolio (UP) based strategies, often rebalance their target portfolio vectors a...

one of the basic assumptions of management accounting illustrate that costschanges has a significance relationship with increasing and decreasing in the levelof activity, recently after being raised of sticky costs issue by anderson and hiscolleagues this assumption was discussed. it means increases in costs by increasingthe more activity level of reduction in costs is exchange for the reductio...

In this paper we explore the practical and welfare implications of a system of voluntary compliance within a market-based environmental regulation. The Substitution Provision of the SO2 emissions trading program allows the owner or operator of an affected electric utility unit to voluntarily designate a non-affected electric unit to become subject to all compliance requirements of affected unit...

This paper estimates the value of international emissions trading, focusing on a here-to-fore neglected component; its value as a hedge against uncertainty. Much analysis has been done of the Kyoto Protocol and other potential international greenhouse gas mitigation policies comparing the costs of achieving emission targets with and without trading. These studies often show large cost reduction...

We show the cost of trading on negative news relative to positive news increases prior to earnings announcements. Our evidence suggests this asymmetry is due to financial intermediaries’ preference to reduce their exposure to risks associated with the announcements. The asymmetry creates a predictable upward bias in prices that increases pre-announcement and subsequently reverses, which confoun...

The U.S. Acid Rain Program is one of the first, and by far the most extensive, applications of a market based approach to pollution control. From the beginning, there has been concern whether utilities would participate in allowance trading, and whether regulatory activity at the state level would further complicate utilities' decision to trade allowances. This paper finds that public utility c...

Linking the EU and Chinese Emission Trading Systems (ETS) increases cost-efficiency of reaching greenhouse gas mitigation targets, but both partners will benefit – if at all to different degrees. Using global computable-general equilibrium (CGE) model DART Kiel, we evaluate effects linking ETS in combination with 1) restricted allowances trading, 2) adjusted allowance endowments compensate Chin...

High penetration of renewable energy source makes microgrid (MGs) be environment friendly. However, the stochastic input from renewable energy resource brings difficulty in balancing the energy supply and demand. Purchasing extra energy from macrogrid to deal with energy shortage will increase MG energy cost. To mitigate intermittent nature of renewable energy, energy trading and energy storage...
