Abstract: This paper addresses the classic issue of measuring the welfare cost of inflation. We extend the New Monetarist framework originated by Largo and Wright (2005) with a price dispersion mechanism similar to Wang (2016) but with the addition of heterogeneous productivity among agents. This productivity is the source of heterogeneous search cost among buyers, and it affects search intensity. Our model suggests that buyers of different productivity choose a different search intensity according to their opportunity cost of search. The low productivity group is inclined to search harder, and as a consequence, there is a positive externality towards the high productivity group since they also benefit from sellers’ price dispersion. Overall, inflation has a distributional welfare effect on heterogeneous agents.

• Trade War in a Two-Country-DSGE Model 

Abstract: This paper examines trade wars in a two-region DSGE model based on a real business cycle framework. In the game, the world consists of two countries, Home and Foreign, which produce different final goods and are linked through trade and an international financial market. Productivity is exogenous and asymmetric in both countries. Governments impose tariffs on imported goods. In a two-player game setting, both governments simultaneously choose tariffs to maximize social welfare. We want to test the hypothesis that trade wars occur due to a catching up effect, as productivity and technology in a smaller economy catches up with that of a larger economy, trade wars become more severe.
