Quarterly Earnings Announcements and Market Risk Adjustments

We examine (1) whether there is a shift in beta for individual securities around quarterly earnings announcements, and (2) whether these beta changes relate to certain characteristics of the firms. We find a statistically significant upward (downward) beta shift during the two-day earnings announcement period for 25 per cent (9 per cent) of a sample of 195 US firms. We also find that the beta shift at the time of the earnings announcement is significantly higher for small firms (i.e., more precise announcements).     

On the Use of Intra-Industry Information to Improve Earnings Forecasts

We investigate whether earnings forecasts are improved by earlier earnings disclosures by firms in the same industry. We find improvements for time series forecasts, but not for analysts' forecasts. Considering prior earnings announcements reduces correlations between forecast errors and security price reactions to earnings announcements, even when incorporating these announcements improves forecast accuracy. Our explanation for this anomaly, which is supported by additional analysis, is that intra-industry information facilitates predicting transitory, rather than permanent, earnings components. The question of whether information transfers improve earnings forecasts provides the context for the analysis, but the primary contribution is the documentation of intra-industry information transfers in a setting other than capital markets.     

The Certification Role of Large Customers in the New Issues Market

This paper examines the certification role of large customers and finds that IPO firms that have product market relationships with large customers experience higher valuation and better long-term performance compared to IPOs without such relationships. This higher valuation is more pronounced when product market relationships are able to alleviate IPO uncertainties, when the businesses of large customers and their IPO suppliers are closely related in downstream markets, and when large customers have stronger certifying abilities. Finally, we find that large customers realize significant positive abnormal returns around their suppliers’ preliminary prospectus filing dates, suggesting that some of the benefits from product market relationships accrue to large customers.     

The Cyclic Behavior of the National Office Market

A review of the post WWII data on national office building construction and vacancy, reveals a recurrent ten-twelve year cycle. Specifying and estimating a structural econometric model for these series leads to several conclusions about this commercial real estate sector. First, the office market appears to "clear" quite slowly, and long-run expectations play an important role in market behavior. Second, supply is definitely more responsive to market conditions than demand. Finally, a six-year forecast suggests that the current over-supply in the market will not go away as fast as in the past.     

A MICROSTRUCTURE ANALYSIS OF THE LIQUIDITY IMPACT OF OPEN MARKET REPURCHASES

We examine the liquidity impact of Canadian open market repurchases and find that spreads are smaller and depths greater during repurchase programs (as compared to the prerepurchase period) and on repurchase days (as compared to nonrepurchase days). We examine the types of orders used by repurchasing companies and find that all repurchase orders are limit orders and more than 70% of these unambiguously add liquidity to the limit order book. The improved liquidity is consistent with U.S. research but different from results from other markets. We attribute the difference to an uptick restriction that limits the aggressiveness of North American repurchases.     

Benchmarks,characteristics and trends of U.S. graduate tax programs awarding a Master of Science in Taxation (MST) degree

Survey data gathered from graduate tax program directors at 26 universities, a response rate of about 43% of all programs contacted, is used to benchmark characteristics and trends of U.S. programs awarding a Master of Science in Taxation (MST) degree. The impetus for this paper was the absence of current literature regarding curriculum, enrollment, and delivery of graduate tax programs in the United States, and it is the first study to compile information on MST program trends.     

Long-Range Dependence in U.S. Home Price Volatility

The existence of GARCH effects in a financial price series means that the probability of large losses is much higher than standard mean-variance analysis suggests. Accordingly, several recent papers have investigated whether GARCH effects exist in the U.S. housing market, as changes in house prices can have far-ranging impacts on defaults, foreclosures, tax revenues and the values of mortgage-backed securities. Some research in finance indicates that the conditional variance of some assets exhibits far greater persistence, or even “long memory”, than is accounted for in standard GARCH models. If house prices do indeed have this very persistent volatility, properly estimating the conditional variance to allow for such persistence is crucial for optimal portfolio management. We examine a number of U.S. metropolitan areas, and find that, for those with significant GARCH effects, more than half indeed exhibit the very high persistence found in other assets such as equities. We also find that, for those markets exhibiting such persistent volatility, C-GARCH models typically do a better job in forecasting than standard GARCH models. Moreover, there is some tentative evidence that metro areas with the fastest appreciation may be most likely to have such long memory conditional variance. These findings should help in improving risk management, through, for instance the construction of better-specified value-at-risk models.     

Further tales of the schism: US accounting faculty and practice credentials

The recent report of the Pathways Commission (American Accounting Association, 2012) contains 22 specific objectives pertaining to the improvement of accounting education. Several of these call for higher degrees of cooperation and collaboration between accounting academics and accounting practitioners. The fact that a schism of sorts has developed between these groups needs to be better understood if progress can be made in bridging that divide. This paper studies one aspect of this issue by focusing on the extent to which accounting academics hold practice credentials. Several hypotheses are offered to explore patterns whereas academics become less likely to share this critical designation with accounting practitioners. The paper suggests that practice credential differences might indicate divergent values and priorities that will pose an obstacle to the cooperation envisioned by the Pathways Commission. Suggestions for reform in ways that would benefit higher education are offered.     

Stochastic frontier models with network selectivity

Worker peer-effects and managerial selection have received limited attention in the stochastic frontier analysis literature. We develop a parametric production function model that allows for worker peer-effects in output and worker-level inefficiency that is correlated with a manager’s selection of worker teams. The model is the usual “composed error” specification of the stochastic frontier model, but we allow for managerial selectivity (endogeneity) that works through the worker-level inefficiency term. The new specification captures both worker-level inefficiency and the manager’s ability to efficiently select teams to produce output. As the correlation between the manager’s selection equation and worker inefficiency goes to zero, our parametric model reduces to the normal-exponential stochastic frontier model of Aigner et al. (1977) with peer-effects. A comprehensive application to the NBA is provided.
