[We use a cost of carry model with nonzero transaction costs to motivate estimation of a nonlinear dynamic relationship between the S&P 500 futures and cash indexes. Discontinuous arbitrage suggests that a threshold error correction mechanism may characterize many aspects of the relationship between the futures and cash indexes. We use minute-by-minute data on the S&P 500 futures and cash indexes. The results indicate that nonlinear dynamics are important and related to arbitrage, and suggest that arbitrage is associated with more rapid convergence of the basis to the cost of carry than would be indicated by a linear model.]

We introduce uncertainty into Holmstrom and Milgrom (1987) to study optimal long-term contracting with learning. In a dynamic relationship, the agent's shirking not only reduces current performance, but also increases the agent's information rent due to the persistent belief manipulation effect. We characterize the optimal contract using the dynamic programming technique in which information rent is the unique state variable. In the optimal contract, the optimal effort is front-loaded and stochastically decreases over time. Furthermore, the optimal contract exhibits an option-like feature in that incentives increase after good performance. Implications about managerial incentives and asset management compensations are discussed.

We hypothesize that cognitive limitation may be manifested in a disproportionately large volume of limit orders submitted at round-number prices if investors use these numbers as cognitive shortcuts. Using detailed limit order data in the Taiwan Futures Exchange, we find that investors with lower cognitive abilities, defined as higher limit order submission ratios at round numbers, suffer greater losses in their round-numbered and non-round-numbered limit orders, market orders, and round-trip trades. The positive correlation between cognitive ability and investment performance is monotonic and robust across futures and options markets. In addition, past trading experience helps mitigate cognitive limitation.

A specific day-trading policy in Taiwan futures market allows an investigation of the performance of day traders. Since October 2007, investors who characterize themselves as “day traders” by closing their day-trade positions on the same day enjoy a 50% reduction in the initial margin. Because we can identify day traders ex ante, we have a laboratory to explore trading behavior without the contamination of potential behavioral biases. Our results show that the 3470 individual day traders in the sample incur on average a significant loss of 61,500 (26,700) New Taiwan dollars after (before) transaction costs over October 2007–September 2008. This implies that day traders are not only overconfident about the accuracy of their information but also biased in their interpretations of information. We also find that excessive trading is hazardous only to the overconfident losers, but not to the winners. Last, we provide evidence that more experienced individual investors exhibit more aggressive day trading behavior, although they do not learn their types or gain superior trading skills that could mitigate their losses.

This paper examines the diversification choices of top managers and their implications for the levels of portfolio equity incentives as well as for firms' financial policies. Standard portfolio theory should also apply to corporate managers and therefore excessive risk exposures to the firm should create portfolio diversification incentives for the managers. We use a unique dataset from the Taiwan tax data center and construct the measures of the degree of diversification in a manager's equity portfolio that is made up of equities of other firms to capture his motives for diversifying his risk exposure to his own firm. We provide empirical evidence supporting the view that managers have a risk-reduction motive when they trade in the equities of other firms besides their own. Moreover, we document evidence that the degree of diversification in such equity portfolios also significantly affects managerial equity incentives as well as firms' financial policies. Overall, our findings confirm that managers' personal diversification can help make up for the diversification that the managers would otherwise have lost, thereby reducing the agency cost of equity incentive contracts.

We compare the sensitivity of managerial cash compensation to firm performance, the level of long term managerial incentives, and the sensitivity of CEO turnover to firm performance for three types of state-controlled Chinese firms: A shares (firms incorporated and listed in mainland China), H shares (firms incorporated in mainland China but listed in Hong Kong), and Red Chip shares (firms incorporated outside mainland China and listed in Hong Kong). We find no difference in the three pay-for-performance sensitivity measures between H shares and A shares. The cash pay-for-performance sensitivity and the level of long-term managerial incentives are higher for Red Chip shares than for the other two firm types. However, the sensitivity of CEO turnover to firm performance is insignificant for all three firm types. Our study illustrates the complexity in the influence of mainland China’s versus Hong Kong’s institutional forces on state-controlled Chinese firms listed in Hong Kong.

We conduct a comprehensive study on the associations between debt covenant violations (“violations”) and auditor actions for financially distressed and nondistressed firms. Our study is motivated by a lack of research on the consequences of violations resulting from auditors' actions. We find that firms with violations have significantly higher audit fees, a greater likelihood of receiving a going‐concern opinion, and a greater likelihood of experiencing an auditor resignation. Importantly, the positive associations hold for all types of firms, including financially nondistressed firms. In fact, we find that, after controlling for other financial information, the relation between violations and an increased likelihood of a going‐concern opinion is stronger for nondistressed versus distressed firms. Our evidence is consistent with belief‐revision research in auditing that finds auditors react more strongly to information that is inconsistent with their prior beliefs. This study provides further evidence on the indirect yet significant consequences of covenant violations on firms resulting from auditor actions.
