31. One concept that is central to Humboldtian science is that of a general equilibrium of forces. 32. Thus, it connects two research fields which were previously unrelated : fair cake-cutting and general equilibrium . 33. Until the 1970s general equilibrium analysis remained theoretical. 34. To model the scale of this effect, economists use computational general equilibrium ( CGE ) models. 35. ZEW s expertise lies particularly in the area of applied microeconometrics and in computable general equilibrium models. 36. Walras'proofs of the existence of general equilibrium often were based on the counting of equations and variables. 37. General equilibrium theory points to a number of difficulties with partial participation ( p . 31 ).38. In contrast, general equilibrium models in the microeconomic tradition typically involve a multitude of different goods markets. 39. Real business cycle modelers sought to build macroeconomic models based on microfoundations of Arrow Debreu general equilibrium . 40. Walras'law was introduced as a theoretical answer to the problem of determining the solutions in general equilibrium .
