Updated 2023-07-20: One year after the original post, I improved the formality a bit and detailed some parts that still today I get emails about them.



The purpose of this post is to offer the author’s view about the conceptualization of what it is to be a successful Ph.D. student and some of the challenges Iberoamerican students face to have an impact.


This post is a personal account based on the author’s experience and what I have learned from friends and acquaintances.


The post presents a short critique of the conceptualization and measurement of scholarly impact and distorted self-metrics.


I will first present my background so the reader can be aware of potential biases in this account. I am a Chilean and studied as an undergraduate in Chile. My major was in Business and Economics, and then I obtained the equivalent of a Master of Arts in Trade Policy and a Master of Science in Statistics. The worst advice I ever got was “your master’s was in Statistics; it is natural to continue a Ph.D. in Statistics.”

I finally decided to continue a Ph.D. after working as a practitioner for several years. I followed that path to develop expertise in critical thinking, project management, and writing. To this day, I consider I can always improve at writing.

During my master’s, I wrote a thesis in International Trade. I am a statistician interested in applying statistical methods to address specific policy-relevant questions, particularly in international trade, migration, investments and theoretically founded empirical work. My work before starting the Ph.D. was focused on three interrelated areas (I hope it keeps that way):

  • Gravity modelling and the role of information on the implications of models
  • Gravity estimation and efficient software implementations
  • Methodology and data compilation practices

After the master’s, I shortly applied to a top Ph.D. in Statistics program at a highly ranked world-class university. Back then, I applied to a program at one university, something that applicants should never do. Now I am at another top program, but this time I have learned that realizing one’s strengths and weaknesses is essential.

Main challenges

European Ph.D. programs focus on a specific training, while the US/Canada feature 1-2 years of general training. Yet, in both cases choosing a field is not a trivial task. I heard before applying that acquired experience before a Ph.D. is critical, such as internships or a master’s degree, and that you need to find a ‘passion.’

In my own experience, after one year in the program, I found all the things I have learned at PUC (Pontificia Universidad Católica de Chile) to be sound. But that is not limited to course contents. At PUC we were told that “We must work well, work with dedication, work at all times. Our work will be contributing directly to the development of society.” That is exactly what you do in a Ph.D. 

One thing is to be able to pass the IELTS test and obtain a good band. Something quite different is to be able to process and elaborate your ideas in a language different from yours. In my case, I translated books, which was easy because I was taking the same order in which somebody else decided to organize their ideas. The challenge in a Ph.D. is to organize your own ideas in a structured way, and that involves learning communication skills that may be different from those you learned in your native language.

There is also the idea of using scholarly metrics from industrialized countries. Those like me, who come from South America, know that research impacting our region must focus on problems no longer part of academic fashion in the developed world.

A Ph.D. program means to become an expert planner. During my first year, I had to face advanced mathematics courses, which involved high-level abstraction and theoretical discussion that I had not previously accessed.

Because of my background, I had to study day and night to level up, yet to find that I would not match with genius-level classmates. In my program, I was in the lower tier because I had classmates who were true geniuses. I saw the same when I switched to a new program, some people have more RAM and processor in their minds than others. You do not need to be a genius to obtain a Ph.D., but you need to be very organized and disciplined.

I never thought about anything significant, like solving P = NP. I want to develop structural methods to translate observed trade policy changes and changes in trade costs into policy guidelines at the national and sectoral levels.

A Ph.D. also involves developing the ability to think in ‘linear’ terms, unlike most college and master’s courses, where project completion is highly rewarded. Doctoral-level courses care about many tiny details. If you can look at abstract problems with a magnifying glass, you might be a successful Ph.D., but there are problems and problems.

In my case, I was interested in problems that ended up poorly fitting in with the discipline and the program. I was aware that the issues I am interested in are at the intersection of Computer Science, Economics and Statistics.

One statistical aspect I love is reading articles and writing software to implement the new methods I find, which has led me to two published articles. Writing software is helpful but will not count towards points to obtain your Ph.D. or give you a tenure-track position. In short, your GitHub profile has a net value of zero in academia. In industry, it is quite a different story.

Distorted self-metrics

As I have mentioned above, a Ph.D. means being a professional planner. In my case, I started a journey of poor diet, insufficient sleep, and studying Monday to Sunday. I fell into the opposite of good planning, drinking coffee at 2 AM on a Wednesday, saying I will recover sleep during the weekend, eating a lot of pizza thinking about eating healthy later.

Even when I knew I would never be like the geniuses in the program, the Ph.D. program involves a lot of consistency and self-discipline. You can obtain your degree with dedication and aligned goals for sure. I repeatedly told myself that I was there “Because I Want to Fit In.”

That idea of fitting in led me to have all my meals in front of the computer or with open books, usually working on a proof while trying to fill all my background gaps. That was self-deceit, it was not productive, and it leads nowhere.

One of the challenges in gravity modelling (my area of interest) is to produce theoretically consistent models that are also computationally efficient. Still, all those abstract courses I took were not pushing me in the direction of doing it better. Another self-deceit is when you consciously ignore that the program is not suitable for you, because you desperately want to obtain the degree at any cost.

Leaving a program

I am older than some of my professors, and I have heard many stories about why people leave. Leaving a program is a decision that has influences from all sides. You may feel it is a failure because you do not fit in, or you can feel it will end up in a conflict with your parents or wife.

Some people leave because of not having the right feeling about the program focus or courses. Others face different issues, such as antisemitism or sexism, which should not happen in an educational context or anywhere.

I wanted to devise a proper measurement of trade frictions, which is crucial for reliable analysis of the impact of international trade and trade policy on welfare and all other economic outcomes of interest to academics and policymakers. Switching programs was the best I could do to achieve that goal.

In my case, I live with a disability, which led me deeply into self-deceit because I did not want to leave the program and send a weak signal. I have often been infantilized or marginalized because of living with a disability, which should enforce the idea of “I don’t have no time for no monkey business” instead of the concept of fitting in.

Unexpected factors

If you apply to a Ph.D. program, many variables affect the result of the application. In my case, I wrote to, interviewed with different professors, and discarded all the options that were not as good back then, because I had limited information or because of the lack of funding.

A Ph.D. program consists of four or more years. During those years, you might (hopefully not!) become seriously ill, get married, move to another city, or get an unexpected, fantastic offer in the industry. This is a summary of some of the things I have heard.

The Ph.D. studies are subject to many external variables as well. We are still in the middle of a pandemic, and COVID-19 influences educational decisions and academic performance. Health also play a role, and I have heard of people who had to leave because of a combination of serious illness and lack of accommodations or understanding.

Concluding remarks

If you are currently doing a Ph.D. and find it is not the right match for you, let me tell you that things have changed on your part, and that is ok. We all change and deal with biased and incomplete information. I have met people in their 2nd or 3rd year who hesitate but decide to stay and graduate, switch programs, or move into the industry. I have not heard a single person complaining after making a mindful decision.

Suppose you are going to apply to a new Ph.D. program. In that case, it is a huge decision, and you were accepted into a previous program, which recognizes your ability and interest in solving problems. The right Ph.D. program for you combines the institution, department, lab and supervisor, and many posts cover why each is important.

There are many alternatives to a Ph.D. I have met people who decided to master out because they did not meet the expectation they wanted, their goals were not aligned with the program, or they just had a good offer from a company such as Google. Leaving a Ph.D. is not the end of life. It is the end of a lifestyle, and you can obtain a shiny top MBA degree or many other more lucrative options than a Ph.D. 

Leaving a program is a weighty decision. Maybe even switching to the same program at another University or Institute or landing at another program is the right step for you. One of the main characteristics of Ph.D. programs is that they are all different.

Maybe you do not think a Ph.D. in Political Science, Economics, or any other discipline is the right match for you. Leaving labels aside, Political Science and all other fields these days cover a broad spectrum of topics. If you are interested in a particular topic and you fit with the organizational culture of a specific lab, leave all prejudice for your own good before deciding.

Don’t panic! The key is knowing where one’s towel is.
