Anybody here an economist? I've read a lot of opinions here and just wondering, that's all. I hear a lot of bad opinions about Keynesianism, which I think has served us pretty well for decades. Peter Ferrara could give a pretty good anti argument, but what nations can he give a working example of that were successful under his brand of economics.
You asked an honest straight question and got a lot of responses spinning off into ideologies. That tells you a lot about the board.
To answer your question, there are at least five college economics teachers who post at least occasionally here (but no one very frequently!). As soon as one of them does they are deluged with people questioning their credentials unless they fawn on Rothbard. There are perhaps another dozen posters who have a good grasp of economics and are willing to actually look up statistics at their sources and read papers rather than simply quote political blogs. That's pretty much it.
So what does a mainstream economist bring to the table (or how can you spot someone with some training)?
1. Real economists have a familiarity with the history of economic thought. They know who physiocrats and mercantilists were and who Adam Smith, David Ricardo, and Thomas Malthus were. This is the Classical period of economic theory. They know who Alfred Marshall is. If they have not read Keynes, they are at least familiar with Hicks and Samuelson. For monetary economics they can discuss Irving Fisher and Milton Friedman. They know what general equilibrium theory is and who Leon Walras, Vilfredo Pareto, and Wassily Leontief were. If none of this rings a bell with someone, they have not read economics.
2. Real economists have learned the basic tools of the discipline. They have a little background in history and in mathematics. They are familiar with econometrics and intelligently discuss forecasting, multiple regression, correlation, and lagged variables.
3. Real economists use simple models but avoid simplistic answers. They know the assumptions they make in using simple models. They are aware of the gaps between data-based econometric models and theory-based models and try to understand how to narrow those gaps.
4. Good amateur economists understand this and are more interested in learning than in defending ideological positions or scoring points. It's the quality of thought that counts. They don't quote (even indirectly) works they have never read or do not understand and they like to look up data.
It goes without saying that people actually interested in economics as opposed to political or ideological flame wars will argue vigorously but refrain from personal attacks. It's hard to learn while you are shouting.
Also note that ideologues never concede a point and think they score victories if they can show someone has changed positions over time. Real economists understand that they can (rarely) be mistaken and that as the data change, institutions evolve, technology develops, and hopefully the state of the economic arts progresses, only fools insist on a rigid consistency.
Arguments are built on reasoning and information. In economics that reasoning includes the models and work of generations of other economists. The information comes from an intimate understanding of data gathering, statistical analysis, and a very large dose of history of both economic conditions and economic thought.
Real economists use these tools and methods to constantly contend and seek to understand what is going on. Poseurs look like they are doing the same in an effort to feel important or advance an ideological agenda.
