On Option-Pricing Models in Real Estate: A Critique

This paper considers the problems peculiar to options on real estate, because of the special set of institutional factors influencing real estate markets. It is intended to serve as a reply to Johnson and Wofford [15] as well as provide an overall critique of option-pricing models in a real estate context. Our major point is that a variety of real estate decisions, such as the abandonment decision, the option to refinance, or the option to exercise a contingent real estate purchase contract, may be modeled using option-pricing techniques. However, both the theoretical and institutional aspects of real estate markets must be taken into account in both developing and applying option models in a real estate context.

Favor in exchange for trust? The role of subordinates’ attribution of supervisory favors

Favor exchange is known to be essential for building personal relationships (guanxi) in China. In two studies, we explore the effect of supervisory favors on subordinates’ trust in supervisor; we further explore how subordinates’ attributions of supervisory favors affect trust in supervisor independently and in interaction with supervisory favors. We find evidence that supervisory favors has a positive effect on trust in the supervisor; merit attribution of supervisory favors has a positive effect on trust in the supervisor but personal favor attribution has a negative effect; merit attribution also moderates the effect of supervisory favors such that supervisory favors has a stronger positive effect on trust in the supervisor for subordinates who make higher merit attribution than for those who make lower merit attribution. Theoretical and practical implications are discussed.     

The Share Price Impact of UK CCA Disclosures

This study investigates the impact of the experimental standard, SSAP16 (Current Cost Accounting), on share returns on the London stock market. Approximately 200 companies were examined between 1980–84. The experimental design specifies current cost as a supplementary signal to historical cost and employs two main statistical tools: ordinary least squares regression and the abnormal performance metric. In addition, a number of different CCA measurements are specified in order to assess the sensitivity of the results and to ease comparison with other studies. The results suggest that CCA information has a small but significant impact on stock returns in the days up to announcement. However, CCA does not seem to be the main driving force behind long period returns. Returns in the long run are associated more closely with historical cost information than with that generated by SSAPI6.     

Spatial Statistics and Real Estate

Real estate has historically employed statistical tools designed for independent observations while simultaneously noting the violation of these assumptions in the form of clustering of same sign residuals by neighborhood, along roads, and near facilities such as airports. Spatial statistics takes these dependencies into account to provide more realistic inference (OLS has biased standard errors), better prediction, and more efficient parameter estimation. This article provides an overview of the field and directs readers to the relevant literature and software.
