An Empirical Analysis of the Effects of Online Trading on Stock Price and Trading Volume Reactions to Earnings Announcements*

This study provides evidence regarding the effects of online trading on stock price and trading volume reactions to quarterly earnings announcements. We test for differences in stock price and volume reactions to quarterly earnings announcements between a period with a significant amount of online trading (1996‐99) and a period without online trading (1992‐95). We conjecture that online trading has increased the proportion of naive investors in the market. We predict that this will result in (1) a decrease in the average precision of investor information prior to earnings announcements leading to higher earnings response coefficients (ERCs), (2) an increase in differential interpretation of earnings leading to higher trading volume reactions that are unrelated to price change, and (3) a decrease in differential prior precision leading to a decrease in the association between trading volume and absolute price change. We find evidence consistent with all three predictions. Our findings are relevant for assessing the validity of concerns about online trading expressed by regulators and the validity of theoretical models of trade with asymmetrically informed investors.     

Further evidence on analyst and investor misweighting of prior period cash flows and accruals

We empirically investigate three questions: (i) whether analysts and investors mis-estimate the persistence of operating cash flows, (ii) if so, is the cash flow effect distinct from the accrual effect in the sense that one effect holds after controlling for the other, and (iii) if these are distinct effects, which effect is stronger in magnitude? We find that prior period operating cash flows have a significant positive effect on forecast errors and stock returns consistent with analysts and investors underestimating the persistence of operating cash flows. Further, we find that not only is the operating cash flow effect distinct from the accrual (more specifically the working capital accrual) effect but it is also considerably larger in magnitude. To our knowledge, this is the first study that documents the relative magnitude of prior period cash flow and working capital accrual effects on forecast errors and stock returns. Our findings have several implications for future research and practice. First, the consistency of results across the two sets of users (analysts and investors) suggests that analyst-forecast inefficiencies are less likely to be driven by their incentives to promote stocks and more likely to be a manifestation of a broader phenomenon that has not been thoroughly investigated in prior studies. Second, for practitioners, our results suggest that a trading strategy based on prior period working capital accruals and cash flows would earn higher abnormal returns than a trading strategy based on accruals alone.     

Relational governance as an interorganizational strategy: An empirical test of the role of trust in economic exchange

We develop a model of relational governance as a specific form of interorganizational strategy that is distinct from the traditional modes of markets and hierarchies. We conceptualize this form of strategy in terms of structural and processual dimensions and derive a model of its determinants through arguments drawn from transaction cost economics and the sociological exchange literature. Hierarchical regression modeling is employed to test the theoretical model on data collected from a sample of 329 independent insurance agencies. We include the relational variable of trust and demonstrate that the combined model explains relational governance better than a model with the traditional determinants of governance form alone. Further, we observe that governance structure and process are related and discuss implications of the dynamic link between them. Directions for extensions are developed for strategic management research and practice.     

Gravitating toward the quadruple helix: international connections for the enhancement of a regional innovation system in Northeast Italy

The majority of previous Regional Innovation System (RIS) studies generally provide a rather static overview of the roles of innovation-creating actors. This article explores a single RIS in Trentino in Italy. The case shows that the roles of three actors (i.e., the provincial government, academia/research centers, and firms) are vital in creating the RIS, and that the provincial-level government policy is important in supporting the innovation activities of regional research institutions and firms aimed at developing their international connections. The public-private research collaboration and international connections of these actors are the key determinants of the development of an advanced RIS, but have largely been ignored in the extant RIS literature. This article extends the existing RIS and Triple Helix research to an international dimension, highlighting the complementary role of international connections within the RIS, thus reflecting a shift toward Quadruple Helix.     

Targets' Accounting Conservatism and the Gains from Acquisition*

We present evidence on the effects of target firms' accounting conservatism in a merger and acquisition transaction. Conservatism is distinct from other accounting or accrual quality constructs examined in prior work. Its unique features can lead to potential benefits for both the targets and the acquirers. The use of conservatism by targets reduces acquirers' risks of acquiring underperforming assets or overpaying for well-performing assets. In addition, targets' conservatism results in greater production of verifiable information that can help the acquirers better estimate and realize synergies of the combined firm. Consistent with these arguments, we find that firms with greater accounting conservatism are more likely to receive a bid. We also find that targets' conservatism increases the deal premium and the announcement returns of both the targets and the acquirers, respectively. Overall, these results indicate that conservatism provides benefits to both sellers and buyers of equity in an acquisition transaction.
