The study proposes and tests a risk-free rate model that simultaneously lets the risk-free rate migrate between rating categories as risk-free rate ranges, and follow a random walk within rating categories as risk-free rate ranges. This is seen as a more accurate modelling of the risk-free rate,...

The paper examines an axiomatic structural approach to term structure decomposition. From this perspective, term structure decomposition is modelled as an non-parsimonious optimization problem, with the structure delineated by constraints related to the likely attributes thereof, rather than by...

The study examines rating migration, and default probability term structures obtained from rating migration matrices. It expands on the use of rating migration matrices with reduced form bond valuation models, by formally delineating the probability of default according to the likely rating...

The paper continues an equity valuation model based on a random process modelling of earnings and book value, coupled with rating categories and rating migration. In essence, earnings and book value probability distributions are related to rating categories, and the probability of an issue to...

The study examines investment readiness (IR) within venture capital (VC) markets, and the cost and resolution thereof. IR impacts VC markets, and the efficiency thereof, in a number of ways. Factors and issues that are raised and considered as part of IR, include: entrepreneurs’ experience and...

The study examines social entrepreneurship from the perspective of: objective and philosophy (why social entrepreneurs are social entrepreneurs), opportunity identification (how social entrepreneurs recognise opportunities), implementation (how social entrepreneurship is implemented), and social...

The study examines the perceptions of entrepreneurs and innovators regarding radical innovation (RI). Emphasis was squarely on the perceptions innovators hold of RI, to lay bare psyche and mindset in this regard. Given this specific focus, experience of RI was not deemed necessary, only general...

Grounded theory is used to examine the relationship between benefit and innovation. The benefits of a broad array of products were considered, and a list of benefit and functionality categories was devised. 84 products were considered, with little (no) restriction on brand, industry, or time...
