This paper examines transactions data regarding the market's reaction to 258 takeover announcements on the Toronto Stock Exchange (TSE) from 1977 to 1989. The study analyzes volatility and volume of target firm's stock during the first trading day following a takeover announcement. A cross-sectional analysis relates this intraday volatility and volume to various aspects of a takeover announcement that proxy for the certainty of payoff to shareholders. Post-announcement volatility is highest when takeover announcements involve share exchange bids which are contested. Trading volume is highest when bids are contested and involve a large initial price change.

Recently developed effort regulation models argue that labor markets are segmented because of differences in the technology of supervision across firms. primary jobs pay above market clearing wages because these jobs are difficult to monitor. Secondary jobs, in contrast, pose no monitoring difficulties and therefore pay a market clearing wage. If, as the literature suggests, increases in employer size make supervision more difficult, we should observe that wages increase with employer size in primary jobs but not in secondary jobs. We test this hypothesis using a switching regression model. We find evidence of an employer size wage effect in both primary and secondary labor markets. However, consistent with the prediction of effort control models, the size effect on wages is considerably larger in primary than secondary jobs.

ABSTRACT We examine the response of informed market participants to the informational signal of auditor changes. Using propensity score matching and difference-in-differences research designs, we document that loan spreads increase by 22 percent on bank loans initiated within a year after auditor changes, increasing direct loan costs by approximately $6.6 million. We also find a significant increase in upfront and annual fees and the probability of pledging collateral, consistent with an increase in screening and monitoring by banks. The increase in spreads is significant for client-initiated auditor changes, with or without disagreements with the auditor, as well as for auditor resignations. Further, the significant increase in loan spreads is documented for upward, lateral, and downward auditor changes. Our results are robust to other proxies for financial reporting quality. Finally, we find no effect resulting from the forced auditor changes due to Arthur Andersen. Collectively, these results suggest that voluntary auditor changes increase information risk, which is priced in private credit markets. JEL Classifications: G20; G21; G32; K22.
