If anyone is interested, I have worked through this exercise myself and my findings are: Additional Costs Year 1 Year 2 Year 3 Total Costs from Above 208.33 233.33 308.33 Number of Eggs Produced by TWO chickens 624 624 624 Additional Average Cost per Egg £0.3339 £0.3739 £0.4941 Food Costs s per Egg per the BBC £0.0350 £0.0350 £0.0350 Total Average Cost per Egg £0.3689 £0.4089 £0.5291 SWITCH to HTML format to read the table properly. So, I demonstrate that it costs more to keep your own chickens than it does to buy from the supermarket. I also mention some of the opportunity costs. I reveal that I can buy fresh large eggs for 10 pence each in Oxford! Finally, I discuss the qualitative factors of keeping the chickens Not such a silly question as you might have thought! There’s definitely a very useful half lesson here for accountants, business students and economists. Duncan Williamson Alright, here you are: forget the AQA, OCR and Edexcel case study analyses for a few minutes and get to grips with a couple of chickens. If you would like to incorporate management accounting with a touch of The Good Life, the environment, GreanPeace, Friends of the Earth and the rest take a look at this page and then answer the question that follows: http://news.bbc.co.uk/1/hi/magazine/3714733.stm Stroll down to the Chickenomics graphic that is followed by a short series of numbers and calculations. Required: the answer provided by the BBC is wrong: suggest the correct answer. (10 marks … or for AQA, 150 marks) Time to fly the coop and begin to sort out the web site: regular visitors be prepared for www.duncanwil.co.uk <http://www.duncanwil.co.uk/> to suffer a possible short loss as I migrate from one ISP to another. Duncan Williamson PS forgive the dig at AQA but I couldn’t resist: I was going to develop it even further but resisted the temptation!
