Teaching trade patterns and trade gains under the Ricardian trade model is one of the most difficult tasks for teachers of international economics. We propose that the utilization of both the PPF and a labor market graph makes the understanding of Ricardian trade gains much easier.

We propose a two-country monopolistic competition model of business service offshoring that captures the advantage conferred by time zone differences. We emphasize the role of the entrepreneurs, who decide how to produce business services (i.e., domestic service provision or service offshoring)....

The main purpose of this study is to illustrate, with simple trade theory, the relationship between competing industrial standards and trade liberalization. We assume that there are two competing industrial standards in an international context, each of which applies to a group of differentiated...

The purpose of this study is to illustrate, with a simple two-region, two-good, two-factor model, how an improvement in one regionfs import infrastructure can affect firmsf location decisions and the nature of the trading equilibrium. It is shown that, through improvements in import...

We propose a two-country growth model of intermediate businessservices trade that captures the role of time zone differences. It is shown that a time-saving improvement in intermediate businessservices trade involving production in different time zones can have a permanent impact on productivity.

In this note, we briefly review the now standard Dixit-Stiglitz-Krugman trade model of monopolistic competition. Furthermore, we propose a convincing graphical exposition that emphasizes the firms' entry-exit process.

Although the one-factor Ricardian trade model with external economies of scale plays a significant role for the understanding of important trade issues under increasing returns, it lacks a compelling graphical representation. We propose a convincing graphical exposition that uses both the PPF...

Although the home-market effect has become one of the most important concepts in both trade theory and the new economic geography, it lacks a compelling graphical representation. The purpose of this note is to offer such a representation. We will decompose the homemarket effect into two steps: a...
