Paul Krugman, a Nobel laureate who also writes a newspaper column, has made a habit of slamming the latest generation of models in macroeconomics for neglecting old-fashioned Keynesian truths. Paul Romer, one of the originators of new growth theory, has accused some leading names, including the Nobel laureate Robert Lucas, of what he calls “mathiness” – using math to obfuscate rather than clarify.
诺贝尔经济学家获得者兼报纸专栏作家保罗·克鲁格曼（Paul Krugman）染上了抨击最新一代宏观经济学模型忽视老派凯恩斯主义真理的习惯。新增长理论创始人之一的保罗·罗默（Paul Romer）也批评一些著名经济学家，包括诺贝尔奖获得者罗伯特·卢卡斯（Robert Lucas）在内，说他们“数学性”（罗默的用语）太重，结果是让问题变得更加模糊而不是更加清晰。
