Default risk cannot explain the Muni puzzle: evidence from municipal bonds that are secured by U.S. treasury obligations

Fama (1977) and Miller (1977) predict that one minus the corporatetax rate will equate after tax yields from comparable taxableand tax-exempt bonds. Empirical evidence shows that long-termtax-exempt yields are higher than theory predicts. Two popularexplanations for this empirical puzzle are that, relative totaxable bonds, municipal bonds bear more default risk and includecostly call options. I study U.S. government secured municipalbond yields which are effectively default-free and noncallable.These municipal yields display the same tendency to be too high.I conclude that differential default risk and call options donot explain the municipal bond puzzle.     

Derivative activities and Asia-Pacific banks’ interest rate and exchange rate exposures

In this paper, we investigate whether the level of derivative activities of Asia-Pacific banks is associated with the market's perception of their interest rate and exchange rate risks. The results suggest that the level of derivative activities (especially interest rate derivatives) is positively associated with long-term interest rate exposure (LTIR) but negatively associated with short-term interest rate exposure (STIR). Further investigations reveal that the positive LTIR exposures are driven by banks with extensive derivative activities. We do not find any significant association between banks’ derivative activities and exchange rate exposure. The significant positive association between the level of derivative activities and LTIR suggests the need for better management of banks’ internal control systems and/or greater derivative disclosure requirements to bring stronger market discipline to banks, particularly for banks with extensive derivative activities.     

Earnings quality and Rule 10b-5 securities class action lawsuits

This study examines the earnings quality of firms sued under accounting-related Rule 10b-5 securities fraud class action lawsuits, following a decline in their stock prices, relative to earnings quality of a return-matched control sample of firms. Our analysis is conducted in pre- and post-Private Securities Litigation Rule Act (PSLRA) periods. We measure accruals (earnings) quality using the Dechow and Dichev (2002) model, and provide evidence of significantly lower quality earnings (earnings overstatement) in both the pre- and post-PSLRA periods, for the test sample firms in the four quarters immediately prior to the sued quarter, followed by a sharp decline in the level of earnings of the sued quarter and subsequent four quarters. These consistent results in the pre- and post-PSLRA suggest that lower earnings quality is merit-related indicia of evidence of fraud and that accounting based securities class action lawsuits target only firms with lower earnings quality. Our findings suggest that further policy reforms making it more difficult for shareholders to file an accounting based securities class action lawsuit would be unwarranted.     

Intangible assets,IFRS and analysts’ earnings forecasts

We investigate whether the adoption of International Financial Reporting Standards (IFRS) in 2005 by Australian firms has been associated with a loss of potentially useful information about intangible assets. We find that the negative association between the accuracy and dispersion of analysts’ earnings forecasts and aggregate reported intangibles previously documented by Matolcsy and Wyatt (2006 ) becomes stronger subsequent to IFRS adoption, primarily for firms with high levels of underlying intangible assets. Our result is largely attributable to reported goodwill, rather than other intangible assets, suggesting that the impairment approach to goodwill valuation required by IFRS conveys more useful information than does the former straight‐line amortization approach. When we investigate a sub‐sample of firms that report lower intangibles under IFRS than under the prior Australian GAAP, we do find some evidence consistent with a loss of useful information relating to intangibles.     

On the Perils of Financial Intermediaries Setting Security Prices: The Mutual Fund Wild Card Option

Economic distortions can arise when financial claims trade at prices set by an intermediary rather than direct negotiation between principals. We demonstrate the problem in a specific context, the exchange of open-end mutual fund shares. Mutual funds typically set fund share price (NAV) using an algorithm that fails to account for nonsynchronous trading in the fund's underlying securities. This results in predictable changes in NAV, which lead to exploitable trading opportunities. A modification to the pricing algorithm that corrects for nonsynchronous trading eliminates much of the predictability. However, there are many other potential sources of distortion when intermediaries set prices.     

On-market share buybacks, exercisable share options and earnings management

Chan et al. (2006b ) suggest that managers might announce a share buyback to manipulate investors’ perceptions and capitalize on the positive price reaction usually associated with the announcement. The incentive to do so is greater when managers have exercisable options. Prior studies document that managers engage in upwards earnings management for opportunistic reasons related to option holdings (Bergstresser and Philippon, 2006). We examine the association between earnings management and exercisable option holdings for buyback firms to investigate if earnings management in the pre‐buyback period is greater for firms with equity incentives to increase share price. Our results, using 138 buybacks over the period 1996–2003, support our prediction. We find that buyback firms with both exercisable options that are in‐the‐money prior to the buyback announcement as well as options that are exercised in the buyback period have higher discretionary current accruals than buyback firms with no exercisable options, unexercised options or with out‐of‐the‐money options. Overall, our results are consistent with buyback firms with exercisable options using earnings management and buyback announcements to maximize option payoffs, and buyback firms without exercisable options signalling undervaluation.     

The influence of business strategy on annual report readability

Concerns about the complexity of firm disclosures have prompted regulators to initiate projects to improve the readability of annual reports. We investigate business strategy as a determinant of annual report readability. As business strategy fundamentally determines a firm’s product and market domain, technology, and organizational structure, it influences a firm’s operating complexity, environmental uncertainty and information asymmetry. Consequently, business strategy frames the level, wording, and complexity of disclosures. We capture a firm’s business strategy based on the Miles and Snow (1978) strategic typology and measure 10-K readability with Li’s (2008) Fog index. We find that firms pursuing an innovation-oriented prospector strategy have less readable 10-Ks relative to firms pursuing an efficiency-oriented defender strategy. We also find that prospectors display more negative and uncertainty tones while defenders exhibit more litigious tone in their 10-Ks. Our study provides useful insights to policy makers as it suggests that efforts to improve annual report readability may be limited for some firms given that business strategy is a fundamental determinant of readability and pronouncements accommodating different strategic orientations are not feasible.     

Improving consumption measurement and other survey data through CAPI: Evidence from a randomized experiment

This paper reports on a randomized survey experiment among 1840 households, designed to compare pen-and-paper interviewing (PAPI) to computer-assisted personal interviewing (CAPI). We find that PAPI data contain a large number of errors, which can be avoided in CAPI. Error counts are not randomly distributed across the sample, but are correlated with household characteristics, potentially introducing sample bias if dubious observations need to be dropped. We demonstrate a tendency for the spread of total measured consumption to be higher on paper compared to CAPI, translating into significantly higher measured inequality. Investigating further the nature of PAPI's measurement error for consumption, we fail to reject the hypothesis that it is classical: it attenuates the coefficient on consumption when used as explanatory variable and we find no evidence of bias when consumption is used as dependent variable. Finally, CAPI and PAPI are compared in terms of interview length, costs and respondents' perceptions.     

The economic costs and benefits of UK defence exports

This study examines the economic costs and benefits to the UK of a 50 per cent cut in UK defence exports from the average level of 1998 and 1999. The net impact on the government budget is estimated to be an ongoing loss of between around £40 million and £100 million a year: around 0.2–0.4 per cent of the total UK defence budget. In addition, there is estimated to be a one‐off net adjustment cost, spread over five years, of between £0.9 billion and £1.4 billion. A further more speculative adjustment cost (estimated at around £1.1 billion) could result if the loss of income associated with the ‘terms‐of‐trade£ effect were also included. In terms of the wider debate about defence exports, the results of this study suggest first that the economic effects of the reduction in defence exports are relatively small and largely one‐off, and secondly that the balance of arguments about UK defence exports should be determined mainly by non‐economic factors.
