Interest-only and principal-only mortgage strips as interest-rate contingent claims

Interest-only (IO) and principal-only (PO) mortgage strips are valued in a stochastic interest-rate environment. The prepayment rate of the underlying mortgages is affected by two considerations not present in the pure financially rational model: (1) The property owner's holding period is assumed to follow a Gamma distribution, resulting in the possibility of prepayment due to the sale of the property (i.e., prepayment that is too early based on market interest rates); and (2) borrowers are assumed to face heterogeneous transaction costs related to refinancing the existing mortgage, and delay refinancing when market conditions make it optimal to do so (refinancing too late). Properties of IO/PO strips are identified by the finite difference method.     

Valuation of SGARAs IN THE Wine Industry: Time for Sober Reflection

The application of AASB 1037 Self Generating and Regenerating Assets provides little guidance to the commercial performance of winemakers. The valuation of grapevines essentially requires the valuation of a segment of a business (vineyards), from which is deducted the value of associated infrastructure. Grapevines are reported at a fictional "net market value" even though they cannot be bought or sold. The combination of recognising revaluation increments as distributable profits through the valuation of grapevines at "net market value", and the subsequent "amortisation" of those revaluation increments over the useful lives of the grapevines, creates a reporting maze which is more likely to confuse than inform.     

Do Daily Price Limits Act as Magnets? The Case of Treasury Bond Futures

This article examines price behavior in the U.S. Treasury bond futures market in the mornings after large overnight price moves, using data from 1980 to 1987. The article tests whether price behavior is affected by proximity to a price limit, and whether the effect is a magnet effect or a calming effect. In that period, the price tends to reverse direction after the morning open, and the reversal appears to reflect a calming effect of the price being close to the limit. An alternative hypothesis—that morning price behavior reflects the overnight price change rather than proximity to the price limit per se—is also tested, and does not perform as well in explaining price behavior.     

How advanced is the strategy paradigm? The role of particularism and universalism in shaping research outcomes

As the field of strategy reaches its 25th anniversary, we examine how far the field has progressed during that time. Both management and strategy research have been characterized as being in an early stage of development. We draw on Kuhn's ( 1996 ) paradigm development model, which posits a connection between a field's stage of maturity and research processes and outcomes, to assess the maturity of the strategy field. We conduct two studies. The first is a cross‐discipline comparison of productivity norms for university faculty. The second study examines longitudinal research outcomes for a sample of 945 strategy faculty. Our results indicate that strategy has the attributes of both an early stage and mature field: while overall research norms are low relative to other fields, they are driven far more by merit‐based than non‐merit factors.

Short-Sale Restrictions and Price Clustering: Evidence from SEC Rule 201

We provide a novel test of information-based theories of price clustering by examining trade, order, and the National Best Bid and Offer (NBBO) quote price clustering during periods when information is removed from the market. We use a natural experiment of short-sale restrictions resulting from Securities and Exchange Commission (SEC) Rule 201 to more effectively determine the impact of information on price clustering. We find evidence of increased price clustering for trades, orders, and NBBO prices during short-sale restrictions. Overall, our findings indicate that short-sale restrictions harm the price discovery process and lead to a reduction in market efficiency.     

Decomposing the market,industry, and firm components of profitability: implications for forecasts of profitability

Academics and practitioners frequently highlight that overall market and industry performance is an important aspect of a firm’s profitability. However, few studies allow for the decomposition of a firm’s profitability into market, industry, and idiosyncratic components, and those that do often assume that the market and industry components are cross-sectional constants. In this study, we allow for variation in firm-specific sensitivities to market, industry, and idiosyncratic economic shocks, and then assess whether and when this decomposition results in improved forecasts of profitability. For the overall sample, we find significant improvements in terms of the magnitude of forecast errors and the frequency with which forecasts based on the decomposed values are superior versus forecasts using only total profitability. Across the sample as a whole, decomposing profitability in the forecasting process results in more accurate forecasts greater than two-thirds of the time (increasing to almost 80% within certain subsamples). Our results provide strong support for the role that firm-specific measures of market and industry profitability play in predicting a firm’s future performance, as well as highlighting settings where the decomposition provides the greatest benefit in terms of predicting future changes in profitability.     

Using Limited Information to Support the Decision to Launch a New Product in the Fruit Juice Market: A Teaching Case Study

Fresh Juice Incorporated (FJI) is in the process of determining whether it should launch a new fruit juice, Genetically Enhanced (GE) Juice. The GE Juice meets consumers' demands for a tasty, nutritious product and it would be the first new juice product in the last fifteen years. Before FJI decides to launch GE Juice, it must analyze the uncertainty surrounding market size, market share, and price of GE Juice. Finally, if FJI decides to launch GE Juice, then they must decide if they will bottle the juice themselves or outsource this process. This case teaches students how to discuss the strategic implications of launching a new product and develop a net present value and financial feasibility simulation model given limited information.     

The influence of relative values of outside director stock options on firm strategic risk from a multiagent perspective

Prior work has examined the effects of absolute levels of outside director stock option grants on risk behavior without recognizing that relative stock option values could differentially affect risk taking. Drawing from the house money effect perspective, we extend this literature by examining how positive deviation from prior outside director option grants values influences firm strategic risk. Additionally we draw from the behavioral agency model and the power literature to develop a multiagent contingency framework suggesting the effect of positive director pay deviation depends on the incentives and power of CEOs reflected in CEO stock ownership and CEO duality, respectively. Our empirical results indicate positive pay deviation has a positive effect on firm risk taking while high ownership and duality independently and jointly weaken this base relationship.
