A proposed Procedure for Facilitating the Analysis of Lease-Purchase Decisions by Consumers

Advertising extolling the advantages of leasing an automobile is increasing, leading many consumers to ask whether leasing makes sense as an alternative to ownership. This paper sets forth a simple procedure which professional financial advisors and educators can use to help consumers make this decision. The procedure can be applied to any buy-lease decision. In what follows, key variables in the buy-lease decision are identified, and an example using actual data is presented to illustrate the procedure.     

Optimal Aggregation of Money Supply Forecasts: Accuracy,Profitability and Market Efficiency

We present a general procedure for aggregating expert forecasts which exploits regularities in the structure of information within the forecaster population. Specific information structures lead to aggregation methods which adjust for additive bias, differences in individual accuracy, and correlation among forecasts. As an application, we construct composite predictions of the weekly change in the money supply from forecasts made by twenty major securities dealers, for which high positive correlation is found to be a significant characteristic. Due to instability in the information structure, our methods cannot improve on the accuracy of a simple average in this case. However, they do capture information about the correlation among money supply forecasts which is not fully impounded in short-term interest rates. Forecasts from our models accurately predict the direction of price changes for Treasury bills and Treasury bill futures after a money supply announcement.     

The Effect of Sequential Information Arrival on Asset Prices: An Experimental Study

A complete understanding of security markets requires a simultaneous explanation of price behavior, trading volume, portfolio composition (ie., asset allocation), and bid-ask spreads. In this paper, these variables are observed in a controlled setting—a computerized double auction market, similar to NASDAQ. Our laboratory allows experimental control of information arrival—whether simultaneously or sequentially received, and whether homogeneous or heterogeneous. We compare the price, volume, and share allocations of three market equilibrium models: telepathic rational expectations, which assumes that traders can read each others minds (strong-form market efficiency); ordinary rational expectations, which assumes traders can use (some) market price information, (a type of semi-strong form efficiency); and private information, where traders use no market information. We conclude 1) that stronger-form market models predict equilibrium prices better than weaker-form models, 2) that there were fewer misallocation forecasts in simultaneous information arrival (SIM) environments, 3) that trading volume was significantly higher in SIM environments, 4) and that bid-ask spreads widen significantly when traders are exposed to price uncertainty resulting from information heterogeneity.     

TALKING ACCOUNTING: AN ETHNOGRAPHY OF MANAGEMENT KNOWLEDGE IN BRITISH AND GERMAN BREWERS

The organisational functionings of accounting hinge on its combination with other forms of organisational knowledge in talk. This paper analyses some of the talk observed in paired situations in British and German brewers, to contrast the intertwining of accounting and other expertise and relate it to the enactment of different organisational orders. Through accounting talk, organisational members air their shifting conceptions of order and, thereby, point to its precariousness and ambivalence. The focus on accounting talk emerges as an approach to the study of the organisational practice of accounting which promises insight into the complex processes of enacting the orders which accounting engenders, their flexibility and fragility. © 1997 Elsevier Science Ltd
