I'm a third year Physics student at Imperial College London, who is considering applying to an Econ PhD program. I cuurently have offers for a Maters in both Theoretical Physics and Economics, and am heavily weighing up both options. I have the following questions: (i) Which Masters program would suit best for the transition? I have an offer for MSc Finance and Economics at the LSE, but I also have offers in Physics from ETH and Imperial. It seems like there could be a possibility to take Econ classes whilst purusing the Physics Masters, which is what I will do if I choose physics. Also, if I do choose the non-physics masters, will other LSE Masters courses, such as the MSc EME or 2-year MSc Economics be more beneficial? (ii) Is it necessary to have research experience in economics? I have set up an RA placement for the summer in the Imperial Finance department, but it is not necessarily in the area I am interested in, namely behavioural economics and decision-making. I have tried (but failed) to successfully cold e-mail professors into giving me a summer reserch in these areas (which is partly why the 2 year LSE course might be better, as it gives more time to be involved in research before the PhD). Would appreciate any insights on this.
