I examine the possibility of information‐based trading in a multiperiod consumption setting. I develop a necessary and sufficient condition for trade to occur. Intertemporal substitution introduces a desire to correlate current consumption with future aggregate shocks. When agents have heterogeneous time‐inseparable preferences, information differentially affects relative preferences for current and future consumption, making information‐based trading mutually acceptable. The no‐trade result continues to hold if there is no aggregate shock, or if agents have either homogeneous or time‐separable preferences.

This paper does three things. First, it explores the type of asymmetry in exchange rate correlation for five inflation-targeting countries. We show their currencies co-move more closely with the currencies of some influential foreign countries during joint appreciations than joint depreciations against a world currency. Second, it establishes empirically the linkage between interest rate differentials and exchange rate correlation. We find evidence that both widening and narrowing interest rate differentials will reduce the correlation. Third, it proposes a new version of the asymmetric dynamic conditional correlation model. The model proves to be capable of providing great insight into the two issues investigated.

This paper examines the effect of trading on earnings management under the setting of China's non-tradable share reform. The government-enforced reform converted non-tradable shares to tradable and thus enabled blockholders and insiders to reduce holdings via public trading. We find significant increases in accruals among Chinese listed companies after the reform. The impact of the reform on earnings manipulations is increasing with the potential for share trading, the degree of information asymmetry and the intensity of stock selling by insiders and blockholders. Our findings support that trading by large shareholders and insiders significantly increases earnings manipulations.

This paper investigates the effects of shareholder protection law on corporate R&D investment. I find that the institutional protection of shareholder benefits reduces both underinvestment and overinvestment in R&D projects. Legal shareholder rights significantly increase R&D investment for firms that may underinvest, but reduce R&D for firms that may overinvest. Shareholder protection further enhances the growth of firms in R&D intensive industries, and promotes the economic growth of innovative countries. The results consistently show that enforcing stronger legal shareholder protection can help firms achieve an overall more efficient capital allocation to productive R&D investment.

This paper examines how conservative accounting affects the relation between accounting data and firm value. The analysis shows that conservative accounting can be characterized equivalently in terms of book value, earnings, or book rate of return. Furthermore, capitalized earnings generally provide a less biased estimate of equity value than book value does. In addition, firm growth affects the way earnings and book value are combined in valuation. A weighted average of book value and capitalized earnings, with the weight on earnings being an increasing and convex function of growth, yields an asymptotically unbiased estimate of equity value. When growth is positive, the weight on book value is negative.

We study the predictive power of option-implied moment risk premia embedded in the conventional variance risk premium. We find that although the second-moment risk premium predicts market returns in short horizons with positive coefficients, the third-moment (fourth-moment) risk premium predicts market returns in medium horizons with negative (positive) coefficients. Combining the higher-moment risk premia with the second-moment risk premium improves the stock return predictability over multiple horizons, both in sample and out of sample. The finding is economically significant in an asset-allocation exercise and survives a series of robustness checks.
