CEO age and tax planning

This study investigates the association between CEO age and corporate tax planning. Using a sample of 11,537 firm‐year observations from the fiscal year 1997–2013, I find CEO age exerts an economically significant influence on firms’ tax policies, incremental to economic determinants identified in prior research. Specifically, CEO age is positively related to cash and GAAP effective tax rates, and negatively related to permanent book‐tax difference, suggesting that older CEOs are less likely to take actions to lower tax burden. The results hold across different model specifications and robustness tests to address potential bias arising from endogeneity, sample selection issue, and the confounding effect of CEO tenure.     

Robust consumption‐investment problem under CRRA and CARA utilities with time‐varying confidence sets

We consider a robust consumption‐investment problem under constant relative risk aversion and constant absolute risk aversion utilities. The time‐varying confidence sets are specified by Θ, a correspondence from [0, T] to the space of the Lévy triplets, and describe a priori drift, volatility, and jump information. For each possible measure, the log‐price processes of stocks are semimartingales, and the triplet of their differential characteristics is almost surely a measurable selector from the correspondence Θ. By proposing and investigating the global kernel, an optimal policy and a worst‐case measure are generated from a saddle point of the global kernel, and they constitute a saddle point of the objective function.     

Market Reaction to Corporate Social Responsibility Announcements： Evidence from China

This study uses an event study methodology to examine how the Chinese market reacts to announcements of involvement in corporate social responsibilitY （CSR） by Southern Weekend （a Chinese newspaper）for Chinese firms from 2008 to 2012. Our results show significant and pcsitive market reactions, supporting the instrumental stakeholder theory. We attribute the positive market response to social capital development and real growth options related to the CSR involvement by the Chinese firms.

Labor Unemployment Concern and Corporate Discretionary Disclosure

We investigate how firms strategically vary their disclosure policies in response to labor unemployment concern. Using changes in state unemployment insurance laws as exogenous variations of labor unemployment concern, we show that firms provide more bad news forecasts when unemployment concern is low. This relation is stronger when firms are financially constrained, when CEOs and CFOs have higher equity incentives, and when workers are likely to be affected more by unemployment. Our findings are not driven by earnings management reversal or underlying performance changes, and are robust to a battery of identification tests. Finally, we find a similar effect of unemployment concern on disclosure using the tone of 10‐K and 10‐Q filings as an alternative proxy for corporate disclosure. Overall, our findings suggest that labor unemployment concern is an important consideration for corporate discretionary disclosure.     

Optimal dynamic reinsurance with dependent risks: variance premium principle

In this paper, we consider the optimal proportional reinsurance strategy in a risk model with two dependent classes of insurance business, where the two claim number processes are correlated through a common shock component. Under the criterion of maximizing the expected exponential utility with the variance premium principle, we adopt a nonstandard approach to examining the existence and uniqueness of the optimal reinsurance strategy. Using the technique of stochastic control theory, closed-form expressions for the optimal strategy and the value function are derived for the compound Poisson risk model as well as for the Brownian motion risk model. From the numerical examples, we see that the optimal results for the compound Poisson risk model are very different from those for the diffusion model. The former depends not only on the safety loading, time, and the interest rate, but also on the claim size distributions and the claim number processes, while the latter depends only on the safety loading, time, and the interest rate.
