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...

Voracious behavior is one of the excess uses of the commons. It is known that the voracity effect can be observed in the economy with common and private capital. We explore another cause of voracious behavior and investigate the effects of voracious behavior on the economy. For this purpose, we...

It is well known that the so-called voracity effect can be observed in an economy with common and private capital. Voracious behavior is regarded as one of the excess uses of the commons. In this paper, we explore a new interpretation of what causes voracious and investigate the effects of...

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 shows that, in a R&D-based growth model in which vertical and horizontal innovations occur simultaneously, increasing the capital income tax leads to faster growth. For this result to hold, the production function for both vertical and horizontal innovations must have constant returns...

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...
