Introducing product compatibility associated with network externalities (hereafter, network compatibility effects) into a horizontally differentiated duopoly model, we consider how network compatibility effects and the level of product substitutability affect endogenous timing decisions in the...

Based on a model of environmental quality differentiated products, we explore how an emission tax charged on consumers who choose an environment-unfriendly good, i.e. a consumer-based emission tax policy, affects the unit emission level of the product, the environment, and consumer and producer...

We examine strategic research and development (R&D) policy for quality-differentiated products in a third-market trade model. We extend the previous work by adding a third exporting country, so that the market structure is international triopoly. We show that the presence of the third exporting...

We provide a simple model of endogenous product compatibility choice under Cournot competition with a network externality. Using the model, we consider how the degree of a network externality and product substitutability affects the choice regarding product compatibility. In particular, if the...

Using the Hamilton–Slutsky extended endogenous timing game of observable delay framework, we analyze the endogenous timing of tariff policy in the presence of a time lag between production and trade decisions. In particular, focusing on the strategic relationships between an importing...

In this paper, we examine strategic R&D policy for quality-differentiated products in a thirdmarket trade model. We extend the previous work by adding a third exporting country, so that the market structure is international triopoly. We show that the presence of the third exporting country...

We examine whether free trade is superior to tariff policy if the government of an importing country cannot precommit to an ex ante optimal tariff rate in the presence of a time lag between production and trade decisions. Based on a simple partial equilibrium model with an export monopoly, we...

Using the Hamilton–Slutsky extended endogenous timing game of observable delay framework, we analyze the endogenous timing of tariff policy in the presence of a time lag between production and trade decisions. We particularly focus on the strategic relationships between the government of the...
