Cambridge Judge Launchpad webinar – The three most important skills for entrepreneurs

13:00 - 14:00

Peter Drucker, the noted management thinker, suggested that entrepreneurs are made, not born – and that the skills of entrepreneurship can be learnt. So what are the most important skills utilised by expert entrepreneurs, and how can they be developed? Drawing on the latest research, Dr Chris Coleridge, Director of the Postgraduate Diploma in Entrepreneurship and the MSt in Entrepreneurship, and Senior Faculty in Management Practice at Cambridge Judge Business School, will talk about which skills give entrepreneurs an advantage as they manage the challenges of starting and developing a business.

Seminar – Experience Markets: An Application to Outsourcing and Hiring

12:30 - 14:00

Dr Catherine Thomas, London School of Economics

Employers in a large online global labour market learn their value for the market only through experimenting. Early experience affects employer selection into posting further jobs, increases the perceived value of using the market, and alters how employers evaluate individual workers. The majority of employers quickly learn that the market is less valuable to them that their next best alternative and exit the market. Participation decisions are relatively insensitive to variation in the hourly wage bids that employers receive and to learning-by-doing in the market. Low market take-up rates are consistent with there being unanticipated and heterogeneous employer costs of reorganising to coordinate remote and fragmented stages of production.

Seminar – Optimal Design for Item Response Theory Models

16:00 - 17:00

Professor Heinz Holling, University of Münster

Optimal design allows for estimating parameters of statistical models according to important optimality criteria, e.g. minimising standard errors of estimators. Thus, optimal designs may considerably reduce the number of experimental units, such as respondents or items in empirical studies. For a long time, optimal design has not received much attention within psychology, but meanwhile interest for this subject is rapidly increasing as such designs are needed, e.g. in large scale assessment, adaptive testing or automatic item generation. In this presentation, first, fundamental principles of optimal design are introduced using well-known linear models, e.g. analysis of variance or simple regression. The rationale of adaptive, Bayesian, and minimax designs needed for nonlinear models will then be outlined. Such designs are presented for Item Response Theory (IRT) models, e.g., 1Pl and 2PL model or linear logistic model. Finally, two R packages for deriving Bayesian and minimax designs based on recently developed algorithms will briefly be demonstrated.
