On the informational content of advice: a theoretical and experimental study

This paper examines the market for advice and the underlying perception that advice is useful and informative. We do this by first providing a theoretical examination of the informational content of advice and then by setting up a series of experimental markets where this advice is sold. In these markets we provide bidders with a demographic profile of the “experts” offering advice.The results of our experiment generate several interesting findings. The raw bid data suggest that subjects bid significantly more for data than they do for advice. Second, in the market for advice there appears to be no consensus as to who are the best advisors although on average economists demand the highest mean price and women suffer a discount. In addition, we find that whether a subject suffers from a representativeness bias in the way he or she processes data has an impact on how he or she bids for advice and on his or her willingness to follow it once offered. Finally, we find that on average people impute a low level of informativeness onto advice, consistent with their bidding behavior for data versus advice.This work was done under grant number SES-0425118 of the National Science Foundation.

A new simple square root option pricing model

This study derives a simple square root option pricing model using a general equilibrium approach in an economy where the representative agent has a generalized logarithmic utility function. Our option pricing formulae, like the Black–Scholes model, do not depend on the preference parameters of the utility function of the representative agent. Although the Black–Scholes model introduces limited liability in asset prices by assuming that the logarithm of the stock price has a normal distribution, our basic square root option pricing model introduces limited liability by assuming that the square root of the stock price has a normal distribution. The empirical tests on the S&P 500 index options market show that our model has smaller fitting errors than the Black–Scholes model, and that it generates volatility skews with similar shapes to those observed in the marketplace. © 2010 Wiley Periodicals, Inc.

Introduction: Globalization and the Workplace in Pacific Asia

Hong Kong's economic successes are evident. As ever, the interpretation of this phenomenon at the level of politics, culture, human capital and business organization is less obvious, though a familiar list of the ‘usual suspects’ of ‘explanations’ has emerged. Hong Kong now faces new and renewed challenges which are linked to shifts in the industrial structure, emerging market demands and the interconnected upgrading of both production and human resources, in addition to the implications of reunification. Key themes of national competitiveness, deindustrialization and the upgrading of production facilities and human resources are all shown to be important, but also multi-layered and hazy concepts.     

An investigation of ingratiation as a career management strategy: evidence from Singapore

In spite of the recognition that career politics, and therefore ingratiation, is widely used to manage careers, there is a dearth of empirical studies on ingratiation as a career management strategy. Consistent with Ferris and Kacmar's (1988) suggestion, the study reported here investigated the conditions (defined by situational variables, career concerns and personality variables) under which ingratiation is used as a career management strategy. Data were obtained through a structured questionnaire from professional employees (N = 214) in public and private sector organizations in Singapore.

Factor analysis of the 21-item career concerns scale revealed four solutions representing internal and external career concerns. The results of the hierarchical regression revealed that situational variables explained most of the variance in ingratiation, followed by career concerns and personality variables. Among the individual variables, task ambiguity, supervisor reward power, managerial responsibility and need for achievement were significant while personal success approached significance. Internal career concern of autonomy development was unrelated to ingratiation. Of the interaction terms, only supervisor reward power and Machiavellianism approached significance. Directions for future studies are suggested.     

Auditors’ decision-making under going-concern uncertainties in low litigation-risk environments: Evidence from Hong Kong

This study examines the audit opinions issued by auditors in a low litigation-risk environment at a time of high economic uncertainty – that of Hong Kong in the period immediately after the Asian financial crisis of 1997. Empirical research using United States data has shown that, contrary to professional guidance which restricts the issue of “disclaimer of opinion” only to situations where existing uncertainties prevent the auditor from forming an opinion, auditors tend to use the “disclaimer” report (in the going concern context) to signal more extreme client firm’s distress. In the high litigation-risk environment of the US, researchers have attributed this tendency to the idea that “disclaimer of opinion” reports are used by auditors to provide some protection against potential legal liability. The results of this study provide evidence that, even in the low litigation-risk environment of Hong Kong, auditors still use “disclaimer” reports to signal more extreme client firm financial distress. Thus, the maintenance of a high litigation-risk environment does not appear to be a necessary pre-requisite for high quality audits.     

The capital market implications of the frequency of interim financial reporting: an international analysis

This study examines empirically the extent to which the frequency of interim financial reporting affects stock price volatility over the course of the fiscal year in four countries with different interim reporting regimes: the United States and Canada with quarterly reporting, and Great Britain and Australia with semi-annual interim reporting. It is hypothesized that, in the tradeoff between timeliness and predictive value of the interim reports, semi-annual interim reporting will lead to lesser price volatility after accounting for other potential influences. These expectations are supported in the results found. Moreover, additional tests conducted on American ADRs of British and Australian companies show that those firms have higher volatility than comparable purely domestic firms on their home stock exchanges.

Bayesian learning and convergence to Nash equilibria without common priors

Summary. Consider an infinitely repeated game where each player is characterized by a “type” which may be unknown to the other players in the game. Suppose further that each player's belief about others is independent of that player's type. Impose an absolute continuity condition on the ex ante beliefs of players (weaker than mutual absolute continuity). Then any limit point of beliefs of players about the future of the game conditional on the past lies in the set of Nash or Subjective equilibria. Our assumption does not require common priors so is weaker than Jordan (1991); however our conclusion is weaker, we obtain convergence to subjective and not necessarily Nash equilibria. Our model is a generalization of the Kalai and Lehrer (1993) model. Our assumption is weaker than theirs. However, our conclusion is also weaker, and shows that limit points of beliefs, and not actual play, are subjective equilibria. Received: March 3, 1995; revised version: February 17, 1997
