This paper explains why trade liberalizations occur in developing countries, and why they are often reversed. It does so by focusing on the use of lobbying for protection by import competing firms as a means to postpone costly product quality upgrades to keep up with foreign competitors. Given...

We provide a unified framework for quantifying the cross-country and cross-sector interactions among trade, innovation, and knowledge diffusion. We study the effect of trade liberalization in an endogenous growth model in which comparative advantage and the stock of knowledge are determined by...

We provide a unified framework for quantifying the cross country and cross-sector interactions among trade, innovation, and knowledge diffusion. We study the effect of trade liberalization in a multi-country, multi-sector endogenous growth model in which comparative advantage and the stock of...

Cultural allegiances whether inherited, imposed or chosen, affect economic activity. Many of these cultural layers – ethnic background, religion, language, ideological orientation, and artistic interests – spill over national boundaries. Cultural ideas travel the world along many routes from...

Innovation, mark-ups and the degree of trade openness vary substantially across sectors. This paper builds a multi-sector endogenous growth model to study the influence of asymmetric trade liberalisation and sectoral differences in the degree of product market competition on the effect that...

Geopolitical conflicts have increasingly been a driver of trade policy. We study the potential effects of global and persistent geopolitical conflicts on trade, technological innovation, and economic growth. In conventional trade models the welfare costs of such conflicts are modest. We build a...

Recent empirical evidence has shown that trade liberalization promotes innovation and productivity growth in individual firms. This paper argues that different types of trade liberalization - multilateral versus regional - may lead to different R&D and productivity levels of firms. Trade...

We show that even in the absence of diminishing returns in production and technological spillovers, international trade leads to a stable world income distribution. This is because specialization and trade introduce de facto diminishing returns: Countries that accumulate capital faster than...

In this paper I study and quantify the long-run effects of openness to trade and multinational production in a model of endogenous innovation with firm heterogeneity. When trade is liberalized, some multinationals find it more profitable to export and forgo the cost of maintaining capacities in...
