Addressing the Bard: Learning Ideas

The Scottish Poetry Library has published a new, provocative and exciting anthology of Burns poems, launched in the Year of Homecoming and of Burns’s 250th anniversary. What makes this anthology different is that twelve contemporary poets have been asked to select one of Burns’s poems and to respond to it. The result is an eclectic collection with some unexpected choices and responses that enlighten, challenge and amuse us. All of the response poems provide insight into Burns’s original work and some may have a more direct resonance with modern readers. In addition to the book itself, these supporting resources are being provided on the Learning and Teaching Scotland website. The material has been developed by Liz Niven, poet, writer, and Scots-language educator, and Maureen Farrell, an English teacher and now teacher educator from the University of Glasgow

Modelling the Incidence of Self-Employment: Individual and Employment Type Heterogeneity

Modelling the incidence of self-employment has traditionally proved problematic. Whilst the individual supply side characteristics of the self-employed are well documented, we argue that the literature has largely neglected demand-side aspects. We explore the determinants of self-employment using individual level data drawn from the U.S. Survey of Consumer Finances (SCF). We present results from an econometric framework, the Parameterised Dogit model, that allows us to separately, and simultaneously, model individual heterogeneity (i.e. supply side) and employment type heterogeneity (i.e. demand-side) influences that determine self-employment. Our findings suggest that whilst individual characteristics are important determinants of self-employment, there are also factors which are specific to the type of employment that influence whether an individual is self-employed

Innovation, Rent Extraction, and Integration in Systems Markets

We consider innovation incentives in markets where final goods comprise two strictly complementary components, one of which is monopolized. We focus on the case in which the complementary component is competitively supplied, and in which innovation is important. We explore ways in which the monopoly may have incentives to confiscate efficiency rents in the competitive sector, thus weakening or destroying incentives for independent innovation. We discuss how these problems are affected if the monopolist integrates into the competitive sector.

A hedonic model of lamb carcass attributes

Lamb carcass value is widely reported to be a function of lean meat yield, which is the relationship between muscle, fat and bone. Five retailers and five wholesalers assessed 47 lamb carcasses from diverse genotypes and scored seven attributes. A hedonic model reveals that conformation attributes were more highly valued (16 c/kg) relative to yield characteristics (4 c/kg). Meat colour and fat distribution were significant for retailers, but less important for wholesalers. Genotype was not a strong indicator of conformation. Eye muscle area and depth were correlated with Fat C; however, these were not significant. These results indicate that carcass conformation, meat colour and fat distribution should be incorporated into carcass grading models.Hedonic, lamb, conformation and meat value, attributes, Livestock Production/Industries,
