This article introduces two methodologies that can be largely useful to empirical analysis in international economics but have not been fully utilized in the field: randomized controlled trials and network analysis. These methods can contribute to a number of topics in international economics including learning by exporting, FDI spillovers, and international diffusion of knowledge and economic shocks, correcting for biases due to endogeneity and specifying channels of diffusion.
The paper develops a three-sector general equilibrium model to examine the consequences of an increase in vocational training costs on internal remittances in a small open dual economy. Using indirect utility functions, the paper endogenizes the internal remittances. The theoretical analysis shows that an increase in vocational training cost of the manufacturing sector decreases internal remittances and the proportion of remittances in migrants‘ income. In addition, an increase in per capita training cost also contributes to expanding the informal sector and contracting the agricultural sector.JEL:R23;I24;J6
This paper investigates the united monetary policy’s and especially QE’s effects on real economies mainly after the ECB’s additional QE implementation periods since December 2015 to January 2018, which is not covered by Suzuki (2016). Author employs the qualitative causal inference methods to verify potential hypotheses. Qualitative causal inferences are useful methods given appropriate sets of potential causal hypotheses are fully specified. ECB’s stimulus of quantity channel (QE channel) and consumption and private investment channel (escaping from balance sheet recession channel) enable Europe to escape from deflation and to promote economic expansion, which is the success of ECB’s united monetary policy so far.
