It is often useful to convert nominal values to real values for applied welfare analysis. This article discusses the use of price deflators, and several published economic indices that may be useful for this process.

This paper develops a new kernel test for neglected nonlinearity in the conditional expectation function, and compares this test to the Ramsey RESET test (1969) and the Neural Net test of Lee, White, and Granger (1993). Like the Neural Test and the Ramsey Reset Test, this Kernel test is a...
