Q:

What is Economic Populism?

I saw an article this morning on NBC declaring that Economic Populism Will Be Front And Center for 2016 Elections. It goes into detail about why this will be such an important issue in the coming year.  
It does not, however, do very much to accurately define what Economic Populism actually is, and my google search for an explanation of the term only brings up a similar article from a year ago, a Wiki article on Populism (but not specifically economic populism) and Huffington Post Articles Tagged As "Economic Populism".
It sounds like it might just be a buzzword without any real meaning, but I wouldn't know since this is the first I've heard of it.  Is there an actual definition for the concept of "Economic Populism"?  And if so, what is it?  

A:

For economic populism as actual economists talk about it, you might want to see macroeconomic populism, usually as observed in Latin America.
Policies include: fiscal stimulus (as opposed to austerity), printing more money, and expanding deficit. This "emphasizes growth and income distribution and deemphasizes the risks of inflation and deficit finance".
There's debate (see this and this) over whether and when there's a right time for macroeconomic populism, but in general it's pretty risky and not a long term solution.

In the context of the 2016 election, "economic populism" refers to a general opposition to income inequality and globalization (ie trade agreements), as well as opposition to money in politics (per the effects of the Citizen United decision). Basically, the middle class is shrinking, jobs are disappearing overseas, and all the politicians are in the pockets of billionaires. Worrying to say the least.
Economists don't really have satisfying answer to these issues - they're a little late to the inequality question, they're firmly in favor of globalization, and money in politics is primarily a political issue, not economic.
So yes, economic populism as used in political writing is a buzzword that has little grounding in actual economics. Probably the closest you get in economics is the work of Thomas Piketty on income inequality, who prescribes progressive taxation.

There's a concept of economic populism but with points to take into account. The first, what you call economic populism in Latin America is known as Economía Solidaria (solidarity economy) which refer to an economy based not in grow the profits or valuate the company but to increase the quality of life through social activities in the community (Concept taken from economiasolidaria.org). Later, both populism and solidarity are used to define the same thing.
The concept was used for the first time in Brazil at the World Social Forum (2001) where they referred this kind of economy as one solution to destroy the gap between social structures. The main institution holding the concept itself are cooperatives around the globe. In the internet world, the solidarity economy is used by most of the open source projects and developers working in free software.
Paul Singer said about the solidarity economy:

"The solidarity economy has emerged as a way out of poverty and continues to do this."

There is also a good paper talking about the economic populism in Spanish called "Economía Popular", where the author explain the main characteristics of the populism and its impacts in the economy. 
Spoiler alert: they have several similarities but in concepts or terminologies are differences.
