500th anniversary of Protestant reformation

May 1, 2017

Bruno Gonçalves Rosi writes on a very important milestone in political and economic history:

This year we celebrate 500 years of the Protestant Reformation. On October 31, 1517, the then Augustinian monk, priest, and teacher Martin Luther nailed at the door of a church in Wittenberg, Germany, a document with 95 theses on salvation, that is, basically the way people are led by the Christian God to Heaven. Luther was scandalized by the sale of indulgences by the Roman Catholic Church, believing that this practice did not correspond to the biblical teaching. Luther understood that salvation was given only by faith. The Catholic Church understood that salvation was a combination of faith and works.

The practice of nailing a document at the door of the church was not uncommon, and Luther’s intention was to hold an academic debate on the subject. However, Luther’s ideas found many sympathizers and a wide-spread protestant movement within the Roman Catholic Church was quickly initiated. Over the years, other leaders such as Ulrich Zwingli and John Calvin joined Luther. However, the main leaders of the Roman Catholic Church did not agree with the Reformers’ point of view, and so the Christian church in the West was divided into several groups: Lutherans, Anglicans, Reformed, Anabaptists, later followed by Methodists, Pentecostals and many others. In short, the Christian church in the West has never been the same.

The Protestant Reformation was obviously a movement of great importance in world religious history. I also believe that few would disagree with its importance in the broader context of history, especially Western history. To mention just one example, Max Weber’s thesis that Protestantism (especially Calvinism, and more precisely Puritanism) was a key factor in the development of what he called modern capitalism is very accepted, or at least enthusiastically debated. But I would like to briefly address here another impact of the Protestant Reformation on world history: the development of freedom of conscience.


On doing economic history (and its importance!)

May 1, 2017

Thanks to Clark medal 2017 , it is one of those rare moments when people are excited about economic history. Though the field is in precarious state  but still atleast there is some discussion. The question is whether it will meet the same fate as the 1993 prize when economic history was honored but again was ignored after some initial excitement.

This post by Vincent Geloso on Notesonliberty blog is a nice read on doing economic history:

And there is economic history properly done. It tries to answer which theory is relevant to the question asked. The purpose of economic history is thus to find which theories matter the most.

Take the case, again, of asymetric information. The seminal work of Akerlof on the market for lemons made a consistent theory, but subsequent waves of research (notably my favorite here by Eric Bond) have showed that the stylized predictions of this theory rarely materialize. Why? Because the theory of signaling suggests that individuals will find ways to invest in a “signal” to solve the problem. These are two competing theories (signaling versus asymetric information) and one seems to win over the other.  An economic historian tries to sort out what mattered to a particular event.

Now, take these last few paragraphs and drop the words “economic historians” and replace them by “economists”.  I believe that no economist would disagree with the definition of the tasks of the economist that I offered. So why would an economic historian be different? Everything that has happened is history and everything question with regards to it must be answered through sifting for the theories that is relevant to the event studied (under the constraint that the theory be consistent). Every economist is an economic historian.

As such, the economic historian/economist must use advanced tools related to econometrics: synthetic controls, instrumental variables, proper identification strategies, vector auto-regressions, cointegration, variance analysis and everything you can think of. He needs to do so in order to answer the question he tries to answer. The only difference with the economic historian is that he looks further back in the past.

The problem with this systematic approach is the efforts needed by practitioners.  There is a need to understand – intuitively – a wide body of literature on price theory, statistical theories and tools, accounting (for understanding national accounts) and political economy. This takes many years of training and I can take my case as an example. I force myself to read one scientific article that is outside my main fields of interest every week in order to create a mental repository of theoretical insights I can exploit. Since I entered university in 2006, I have been forcing myself to read theoretical books that were on the margin of my comfort zone. For example, University Economics by Allen and Alchian was one of my favorite discoveries as it introduced me to the UCLA approach to price theory. It changed my way of understanding firms and the decisions they made. Then reading some works on Keynesian theory (I will confess that I have never been able to finish the General Theory) which made me more respectful of some core insights of that body of literature. In the process of reading those, I created lists of theoretical key points like one would accumulate kitchen equipment.

This takes a lot of time, patience and modesty towards one’s accumulated stock of knowledge. But these theories never meant anything to me without any application to deeper questions. After all, debating about the theory of price stickiness without actually asking if it mattered is akin to debating with theologians about the gender of angels (I vote that they are angels and since these are fictitious, I don’t give a flying hoot’nanny). This is because I really buy in the claim made by Douglass North that theory is brought to life by history (and that history is explained by theory).


How Hawaii broke up from the US monetary union…(Why there is hardly any discussion on break up of Indo-Pak monetary union?)

May 1, 2017

Brilliant JP Koning has another superb post. He has a knack for drawing our attention to episodes from monetary history on which most of us are just clueless. Blame it on the teaching of economics which lays far more importance on theories and methods than learning about the subject from narration of historical events.

He points how Hawaii exited from US monetary  Union during the 1942 Pearl Harbour attacks: has interesting lessons for the Euro break-up:
