We consider a dynamic voluntary advertising model with a duopoly. Firms can use advertising and price as competitive tools where product quality is a given and the market is not fully covered by consumers. Advertising also plays a role as a public good. In this situation, we investigate how...

In this paper, we construct a simplified general oligopolistic equilibrium (GOLE) model, in which Smith's (1776) famous theory of division of labor is embedded. In the absence of labor market integration with trading countries, we show that trade liberalization promotes a reduction of the number...

This paper incorporates the efficiency wage model of Shapiro and Stiglitz (1984) into a general oligopolistic equilibrium model of Neary (2009). We show that the pro-competitive effect stemming from trade liberalization increases the real wage of employees and relaxes the non-shirking condition....

We investigate the dynamic relationship between advertising and product quality under duopolistic competition. By using a simplified vertical product differentiation model with voluntary advertising, we show that the firm with larger market share has a larger advertising share and that there is...

In this study, we analyze a dynamic duopoly game in which firms can use advertising and price as competitive tools. The market is assumed to be completely covered in the sense that all consumers purchase a product from one of the two firms. We assume that advertising creates a positive...

This paper develops a dynamic Ricardian trade model with a supply of productive infrastructure in the manufacturing sector. We discuss the onset of trade liberalization when the home country has a (dynamic) comparative advantage in the manufacturing sector. Moreover, we compare over time the...

This study constructs a general oligopolistic equilibrium model in which Smith’s (1776) famous theory of the division of labor under vertical specialization is embedded. We demonstrate that a pro-competitive government policy weakens the division of labor and hence reduces firm productivity,...
