The dual nature of trade: measuring its impact on imitation and growth
Imports of goods that embody foreign technology raise a country's output directly as inputs into production and indirectly through reverse-engineering of these goods, which contributes to domestic imitation and innovation. This paper first quantifies spillovers from high-technology imports from developed countries to domestic imitation and innovation in both developed and developing countries. It then considers the contribution of foreign and domestic innovation to real per capita GDP growth. ; International patent data for forty countries from 1970 to 1985 are used to create proxies for ...
The Global Financial Resource Curse
Since the late 1990s, the United States has received large capital flows from developing countries and experienced a productivity growth slowdown. Motivated by these facts, we provide a model connecting international financial integration and global productivity growth. The key feature is that the tradable sector is the engine of growth of the economy. Capital flows from developing countries to the United States boost demand for U.S. non-tradable goods. This induces a reallocation of U.S. economic activity from the tradable sector to the non-tradable one. In turn, lower profits in the ...
Markets, Externalities, and the Dynamic Gains of Openness
Inflows of foreign knowledge are the key for developing countries to catch up with the world technology frontier. In this paper, I construct a simple tractable model to analyze (a) the incentives of foreign firms to bring their know-how to a developing country and (b) the incentives of domestic firms to invest in their own know-how, given the exposure to foreign ideas and competition. The model embeds two diffusion mechanisms typically considered separately in the literature: externalities and markets. The dynamic gains of openness can be substantial under either mechanism, but their relative ...
Endogenous Borrowing Constraints and Stagnation in Latin America
The Latin American debt crisis of the 1980's had a major and long lasting effect on per-capita consumption: its level in 2005 was not that different from that in 1980. This paper studies the long stagnation in per-capita consumption that followed the crisis, and its relationship with recessions and sovereign risk, using a small open economy real business cycle model with complete markets, endogenous borrowing limits (limited commitment), endogenous capital accumulation, and domestic productivity and international interest rate shocks. I find that the model does an excellent job at explaining ...
Innovation, Diffusion, and Trade: Theory and Measurement
I develop a multicountry-model in which economic growth is driven mainly by domestic innovation and the adoption of foreign technologies embodied in traded intermediate goods. Fitting the model to data on innovation, output per capita, and trade in varieties for the period 1996-2007, I estimate the costs of both domestic innovation and adopting foreign innovations, and then decompose the sources of economic growth around the world. I find that the adoption channel has been especially important in developing countries, and accounts for about 65% of their ?embodied? growth. Developed countries ...
The Evolution of Comparative Advantage: Measurement and Implications
We estimate productivities at the sector level for 72 countries and 5 decades, and examine how they evolve over time in both developed and developing countries. In both country groups, comparative advantage has become weaker: productivity grew systematically faster in sectors that were initially at greater comparative disadvantage. These changes have had a significant impact on trade volumes and patterns, and a non-negligible welfare impact. In the counterfactual scenario in which each country's comparative advantage remained the same as in the 1960s, and technology in all sectors grew at the ...
Optimal Monetary Policy in an Open Emerging Market Economy
The majority of households across emerging market economies are excluded from the financial markets and cannot smooth consumption. I analyze the implications of this for optimal monetary policy and the corresponding choice of domestic versus external nominal anchor in a small open economy framework with nominal rigidities, aggregate uncertainty and financial exclusion. I find that, if set optimally, monetary policy smooths the consumption of financially excluded agents by stabilizing their income. Even though Consumer Price Index (CPI) inflation targeting approximates optimal monetary policy ...
The Global Diffusion of Ideas
We provide a tractable theory of innovation and technology diffusion to explore the role of international trade in the process of development. We model innovation and diffusion as a process involving the combination of new ideas with insights from other industries or countries. We provide conditions under which each country's equilibrium frontier of knowledge converges to a Frechet distribution, and derive a system of differential equations describing the evolution of the scale parameters of these distributions, i.e., countries' stocks of knowledge. In particular, the growth of a country's ...
World Productivity: 1996 - 2014
We account for the sources of world productivity growth, using data for more than 36 industries and 40 major economies from 1996 to 2014, explicitly taking into account changes in the misallocation of resources in labor, capital, and product markets. Productivity growth in advanced economies slowed but emerging markets grew more quickly which kept global productivity growth relatively constant until around 2010. After that, productivity growth in all major regions slowed. Much of the volatility in world productivity growth reflects shifts in the misallocation of labor across countries and ...
