We introduce a preference for wealth into the standard search and matching model to analyze the labor market when there is persistent demand shortage. We show that, under some conditions, a secular stagnation steady state exists in which the economy permanently operates below capacity due to...

We examine the effect of immigration on the host country in the dynamic model that can deal with secular unemployment. Immigration has contrasting effects, depending on the economic state of the host country. If there is unemployment, immigration worsens unemployment and decreases consumption by...

We theoretically analyze the effects of a child allowance, an improvement in the efficiency of child rearing and a labor income tax on the fertility rate and per capita consumption. The effects on per capita consumption are opposite in the absence, and the presence, of unemployment. For example,...

We develop an aggregate demand analysis of a small open economy based on all agents' dynamic optimization. Murota and Ono (2015) present a simple Keynesian cross analysis with dynamic optimization. This paper extends it to a small-country setting with two factors and two commodities, of which...

We examine whether cooperation in R&D leads to product market collusion. Suppose that firms engage in a stochastic R&D race while maintaining the collusive equilibrium in a repeated-game framework. Innovation under competitive R&D creates inter-firm asymmetries, which destabilizes the collusive...

The U.S. has been under pressure to abandon the unique first-to-invent feature of its patent law for awarding patents. The opposition to reform however argues that switch to a first-to-file rule, the international norm, will undermine innovation. We evaluate this argument in a dynamic stochastic...

Host country governments often grant investment incentives to foreign firms locating in their territories. We show that such preferential treatment of foreign firms can facilitate transfer of foreign technology, induce entry by the local firm, and increase host country welfare. However, this...

We present a new model of dynamic Bertrand competition, where a quota is treated as an intertemporal constraint rather than as a capacity constraint as is common in the literature. The firm under a quota then can still vary the rates of exports over time provided that its total sales within the...

We examine the role of cost uncertainty in a firm’s choice between exporting and foreign investment in oligopolistic industry. We consider both foreign direct investment and an international joint venture, and allow country-specific and firm-specific cost uncertainty. Unlike exporting, either...

Antidumping (AD) petitions are often withdrawn in favor of VERs and price undertakings. We compare foreign firms’ incentive to engage in foreign direct investment (FDI) under a VER and a price undertaking, with special emphasis on foreign rivalry. We show that a VER is less likely to induce...
