Inflation and Innovation in a Schumpeterian Economy with North–South Technology Transfer

This study analyzes how inflation affects innovation and international technology transfer via cash‐in‐advance constraints on R&D. We consider a North–South quality‐ladder model that features innovative Northern R&D and adaptive Southern R&D. We find that higher Southern inflation causes a permanent decrease in technology transfer, a permanent increase in the North–South wage gap, and a temporary decrease in the Northern innovation rate. Higher Northern inflation causes a temporary decrease in the Northern innovation rate, a permanent decrease in the North–South wage gap, and ambiguous effects on technology transfer. Finally, we calibrate the model to China–U.S. data to perform a quantitative analysis.     

NONPARAMETRIC LIKELIHOOD: EFFICIENCY AND ROBUSTNESS*

Nonparametric likelihood is a natural generalization of parametric likelihood and it offers effective methods for analysing economic models with nonparametric components. This is of great interest, since econometric theory rarely suggests a parametric form of the probability law of data. Being a nonparametric method, nonparametric likelihood is robust to misspecification. At the same time, it often achieves good properties that are analogous to those of parametric likelihood. This paper explores various applications of nonparametric likelihood, with some emphasis on the analysis of biased samples and data combination problems.
