We propose a stochastic control model to study corporate investment with generalized investment frictions, including investment lags and various of adjustment costs. We find that the dominance of the ``good news principle'' or ``bad news principle'' is determined by the joint effect of...

The poor thermal performance of prefabricated house roof in severe cold area results in the increase of heating energy consumption and uncomfortable indoor thermal environment. Roof energy-saving retrofits are necessary, and the specific retrofit measures are investigated from the perspective of...

The tanglesome environments of high radiation and strong acid or alkali lead to the currently reported materials used to detect ReO4− (surrogate for 99TcO4− with nonradioactive) far from meeting the requirements of practical applications. Here, we report the ionic liquids modified covalent...

The fundamentals of promoter effects in the Fischer−Tropsch synthesis over Co-based catalysts were systematically investigated by employing the Rh, Ir, Sb and Ga as promoters of Co/Al 2 O 3 . Various characterizations showed the higher dispersion and reducibility over Rh- and Ir- promoted...

Exciplex has long been recognized as a mixture of donor and acceptor components. Here, for the first time, it was demonstrated that exciplex emission can also be achieved by single pure molecule, we named it as homojunction exciplex (ho-exciplex). By using the flexible alkyl chain to link the...

Hedge fund activism refers to the phenomenon where hedge fund investors acquire a strict minority block of shares in a target firm and then attempt to pressure management for changes in corporate policies and governance with the aim to improve firm performance. This study provides an updated...

This paper formalizes a novel form of corporate insider trading based on non-insider information. In our model, insiders make trading decisions in anticipation of activist intervention. Because insiders have access to private information about firm fundamentals, they can better separate...

With the accelerated financialization of energy, the spillovers between energy and financial markets is becoming an important issue. This paper compares the characteristics of spillover effects between China and the US markets using the method of generalized variance decomposition due to...

We examine the effect of corruption costs on corporate disclosure of major customers. Using a panel data set for Chinese listed firms over the period 2009-2017 and difference-in-differences estimations, we find that firms with more potential sales-related corruptions respond to the Chinese...

We develop a machine learning method to mitigate investor irrationality in copy trading. Copy trading allows layman investors (followers) to evaluate and copy expert traders’ transactions. The key challenge faced by followers is choosing which traders to follow. We observe a prevalence of...
