Transform analysis for Hawkes processes with applications in dark pool trading

Hawkes processes are a class of simple point processes that are self-exciting and have a clustering effect, with wide applications in finance, social networks and many other fields. This paper considers a self-exciting Hawkes process where the baseline intensity is time-dependent, the exciting function is a general function and the jump sizes of the intensity process are independent and identically distributed nonnegative random variables. This Hawkes model is non-Markovian in general. We obtain closed-form formulas for the Laplace transform, moments and the distribution of the Hawkes process. To illustrate the applications of our results, we use the Hawkes process to model the clustered arrival of trades in a dark pool and analyse various performance metrics including time-to-first-fill, time-to-complete-fill and the expected fill rate of a resting dark order.     

Carbon Price in China: A CO2 Abatement Cost of Wind Power Perspective

As a result of rapid development of industrialization and urbanization, energy (especially fossil fuels) demand growth is increasing. Hence, China is facing the huge pressure of environmental protection and CO₂ emission reduction. The feed-in tariff (FIT) policy that promotes more wind power to substitute for thermal power and a well-functioning carbon price mechanism can significantly affect CO₂ abatement, and both can work in coordination to achieve emission reduction. Using panel model, we prove that FIT policy is more effective than other policies in promoting more wind power. Also the slowdown of economic growth, energy substitution, technological progress, and CO₂ mitigation requirement can stimulate the expansion of wind power. Additionally, based on the calculation of real abatement cost of wind power, we obtain the provincial and national average of carbon prices (239 CNY/ton and 242 CNY/ton). Specifically, 233-251 CNY/ton will be the range for reasonable carbon price in the future. We find that the carbon prices in this article are higher than those of the emissions trading scheme pilots in 2014 and 2015, due to the relatively high proportion of free allowance. Based on the above conclusions, we proposed some policy suggestions.

Evidence of feedback trading with Markov switching regimes

Previous research has concluded that the degree of return autocorrelation observed in index returns varies linearly with the volatility of the series, and that feedback traders are at least partly responsible for this phenomenon. Using daily Australian bond and equity market returns, we test this conclusion directly by using a Markov switching model for changing variance that explicitly allows the autocorrelation of returns to vary with the volatility regime. We find evidence that a significant proportion of investors in both the Australian equity and bond markets are positive feedback traders and are responsible for the observed increase in negative autocorrelation in index returns during periods of high and increasing volatility.

Trading on inside information when there may be tippees

This paper compares four scenarios of a model in which, for the possible presence of tippees, firm insiders may not be the only persons having inside information. The four scenarios are that of free insider trading, that with a ban on insider trading, that of observable insider trading, and that with full disclosure of information. Each of these scenarios is shown to be strictly more efficient than the one before so long as there is a positive probability that a tippee exists. The paper sheds some light on why and how insider trading should be regulated, and also on the role of the disclosure system in the overall scheme of securities regulation.

What's in a name.com?: The effects of ‘.com’ name changes on stock prices and trading activity

This paper uses a market signaling perspective to examine investor reactions to firm announcements of name changes to include ‘.com.’ Firms that change their name as a purely cosmetic technique are contrasted to those that employ other strategic investments. Results show that announcements of ‘.com’ name changes are associated with significant increases in stock prices and trading activity. Furthermore, the magnitude of investor reactions is significantly larger when name changes are accompanied by other strategies. Copyright © 2001 John Wiley & Sons, Ltd.     

Critically Interrogating Eco‐Homes

Eco‐homes have only been researched in fragmented and partial ways, which fail to adequately examine their complexities and possibilities. Numerous myths about eco‐homes persist in the public imagination and policy support has been mixed with, in practice, little change to the construction of contemporary homes. The ecological and social potential of eco‐homes are being undermined by a technocratic focus, the capacity and behaviour of occupants, and a weakening of design as developments are scaled up. This intervention identifies five ways in which eco‐homes need to be more robustly interrogated to strengthen their potential, through their breadth and diversity, dynamic nature, socio‐material interdependencies, place, and understanding of their political economies. Crucially these interrogations need to be researched simultaneously to ensure that the full diversity of eco‐homes is understood through their multiple interdependencies, multi‐scalar practices and materialities.

Information asymmetry, speculation and foreign trading activity: Emerging market evidence

This paper provides evidence on the relation between private-information-based trading and foreign trading activity on the Istanbul Stock Exchange (ISE). We use a recently developed model that utilizes information in volume-return dynamics of individual stocks and show that variables such as size and Tobin's Q explain the extent of speculative activity across firms traded on the ISE. We present evidence supporting the notion that foreign trading activity is associated with informed trading on the ISE. Implications of our findings for emerging markets research are also discussed.
