This paper develops a two region model of trade to study the relationship between geographic patterns of industry and economic growth without scale effects. With transport costs, imperfect knowledge diffusion, and perfect capital mobility, firms locate production, process innovation, and product...

This paper investigates the relationship between geographic patterns of industry and economic growth in a two-country model of trade with no scale effect, where productivity growth is generated by firm investment in process innovation. We find that dispersed equilibria with industry located in...

This paper examines the impacts of country-specific network costs that are provided by a capital-intensive communications sector in a two-country two-factor model, where there are two trading sectors, agriculture and manufacturing. It is shown that when firms in the manufacturing sector incur a...

This paper examines researchers' choices between either collaborating with venture capitalists (Regime C) or going independently (Regime I), and how their interaction affects long-run endogenous growth, in an economy characterized by incomplete contracts and financial market imperfections. Both...

This paper develops a two country model to investigate the effects of national R&D subsidies on aggregate product variety and endogenous productivity growth without scale effects. In particular, monopolistically competitive firms invest in process innovation with the aim of lowering production...

This note examines the effect of per-period communication costs in a model of expanding product variety. It is shown that while a decrease in communication costs leads to growth in aggregate output, this growth is only transitional with the growth rate falling to zero in the long run as the...
