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.     

Relationship equity and switching behavior in the adoption of new telecommunication services

This paper first defines and then presents a model of “relationship equity” for business markets. It points out that the potential benefits of managing relationship equity have been largely ignored and that a general model and stream of relevant research questions could be useful to marketing and relationship practitioners. The model developed considers the special case of key account management as antecedent, two different types of moderator variables, relationship equity as a perception by the buyer, and switching behavior via adoption of new telecommunication services as a result of this perception. The model is used as a basis for developing a number of working propositions.     

The impact of monetary policy on asset prices

Estimating the response of asset prices to changes in monetary policy is complicated by the endogeneity of policy decisions and the fact that both interest rates and asset prices react to numerous other variables. This paper develops a new estimator that is based on the heteroskedasticity that exists in high-frequency data. We show that the response of asset prices to changes in monetary policy can be identified based on the increase in the variance of policy shocks that occurs on days of FOMC meetings and of the Chairman's semi-annual monetary policy testimony to Congress. The identification approach employed requires a much weaker set of assumptions than needed under the “event-study” approach that is typically used in this context. The results indicate that an increase in short-term interest rates results in a decline in stock prices and in an upward shift in the yield curve that becomes smaller at longer maturities. The findings also suggest that the event-study estimates contain biases that make the estimated effects on stock prices appear too small and those on Treasury yields too large.     

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.
