Our favorite caricature of a post-doctoral researcher: a frail man (or woman) with unkempt hair, hunched in front of a computer screen, with a half-filled cup of coffee by his side. As the coffee gets colder and time flies by, he appears oblivious to his surroundings. He is happy spending long hours at his desk conceptualizing arcane theory on obscure topics the real world does not care about. He is in a state of eternal "tapasya" – meditating on his eternal love-affair with knowledge…because life is an eternal quest for knowledge! Or, so the world believes. Once the PhD has been completed, and freshly-minted researchers decide that research is what they would like to do for the rest of their lives, their friends and family might start assuming that a Doctor of Philosophy is just another armchair intellectual.

A PhD is a life choice. One of the crucial factors that a potential graduate student should account for is that doing a PhD in the US can be a completely different experience from doing a PhD in Italy, Germany, or elsewhere in Europe.

Doing an economics PhD will make you an expert in your research topic, but, beyond that, it will also teach you a number of valuable lessons which are applicable to other jobs and your personal life. Here are some of the most useful lessons that you'll learn from undertaking your own independent research project. If you plan to start your PhD application this autumn, download our free guide "How to successfully apply to a PhD in Economics".
