International Outsourcing,Tax, and Patent Protection

We show the implications of strengthening patent protection in a developing country in the presence of a vertical technology transfer, which, despite its empirical relevance, did not get due attention in the literature. We show that if there is imperfect knowledge spillover under a weak patent protection, a strong patent protection in the developing country increases the profit of the developed‐country firm if there is a uniform tax rate in the developing country. However, if there is either perfect knowledge spillover under weak patent protection or discriminatory tax policy in the developing country, the profits of the developed‐country firms are the same under weak and strong patent protections in the developing countries.     

A Note on the Adverse Effect of Competition on Consumers

It is usually believed that higher competition, implying more active firms, benefits consumers. We show that this may not be the case in an industry with asymmetric cost firms. A rise in the number of more cost‐inefficient firms makes the consumers worse off in the presence of a welfare‐maximizing tax/subsidy policy. A rise in the number of more cost‐inefficient firms also reduces social welfare.
