The North produces differentiated intermediate factors in monopolistically competitive firms.North and South produce consumption goods using the finite number of factors. The world optimum can be achieved through a combination of ad valorem and specific production subsidies, which converges to a...

This paper proposes a trade model with heterogeneous firms that decide not just whether and how much to export but also whether and how much to innovate. Incorporating both the extensive and intensive margins of trade and innovation leads to different possible equilibria. Depending on how costly...

Technological leadership has shifted at various times from one country to another. This analysis proposes a mechanism that endogenously explains this perpetual cycle of technological leapfrogging by incorporating international knowledge spillovers into a two-country dynamic model of innovation...

We develop a two-country (Home and Foreign) by two-good (consumption good and investment good) by one factor (capital) endogenous growth model with international knowledge spillover to study the relationship between an import tariff and economic growth and welfare. First, unlike the past...

This paper studies the relationship between tariffs and economic growth in a two-country AK growth model. We find that a sufficiently higher tariff can increase or decrease economic growth, which depends on the levels of productivity coefficients in both countries. Moreover, the Ricardian...

A two country, three sector hybrid model of structural change with distortionary government policies is used to quantify the impact of international trade and trade reform for industrialization. The model features Arming- ton motivated trade in agriculture and industry, and a novel...

We develop a two country, three-sector model to quantify the effects of Korean trade policies for structural change from 1963 through 2000. The model features non-homothetic preferences, Armington trade, proportional import tariffs and export subsidies, and is calibrated to match sectoral value...

The majority of innovations are developed by multi-sector firms. The knowledge needed to invent new products is more easily adapted from some sectors than from others. We study this network of knowledge linkages between sectors and its impact on firm innovation and aggregate growth. We first...

This paper shows that the results of Bianco (2006) depend critically on the assumption that there are no difference between the intermediate goods share in final output, the returns of specialization and the degree of market power of monopolistic competitors. In this paper, we disentangle the...

Can a transfer of wealth from the US to least developed countries be Pareto improving? We analyze this question in an open-economy innovation-driven growth model, in which the high-income (low-income) country produces innovative (homogenous) goods. We find that wealth redistribution to the...
