How Times Have Changed: The Impact of the 2026 Iran War on the U.S. Economy

The 2026 Iran war has raised the question of how exposed the U.S. economy is to geopolitical oil supply disruptions. It is widely believed that the U.S. economy has become less vulnerable to such disruptions as it has reduced its dependence on oil and changed from a major net oil importer to a net oil exporter. We develop a two-country model of the global economy with large geopolitical oil supply disruptions that distinguishes between the U.S. economy and the rest of the world. We find that the response of U.S. real GDP growth to the disruption in global oil supplies today is only ...

Productivity, Tradability, and the Long-Run Price Puzzle

Long-run cross-country price data exhibit a puzzle. Today, richer countries exhibit higher price levels than poorer countries, a stylized fact usually attributed to the "Balassa-Samuelson" effect. But looking back fifty years, or more, this effect virtually disappears from the data. What is often assumed to be a universal property is actually quite specific to recent times. What might explain this historical pattern? We adopt a framework where goods are differentiated by tradability and productivity. A model with monopolistic competition, a continuum-of-goods, and endogenous tradability ...

Risk sharing in a world economy with uncertainty shocks

This paper analyzes the effects of output volatility shocks and of risk appetite shocks on the dynamics of consumption, trade flows and the real exchange rate, in a two-country world with recursive preferences and complete financial markets. When the risk aversion coefficient exceeds the inverse of the intertemporal substitution elasticity, then an exogenous rise in a country?s output volatility triggers a wealth transfer to that country, in equilibrium; this raises its consumption, lowers its trade balance and appreciates its real exchange rate. The effects of risk appetite shocks resemble ...

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 ...

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 ...

Oil, Volatility and Institutions: Cross-Country Evidence from Major Oil Producers

This paper examines the long-run effects of oil revenue and its volatility on economic growth as well as the role of institutions in this relationship. We collect annual and monthly data on a sample of 17 major oil producers over the period 1961-2013, and use the standard panel autoregressive distributed lag (ARDL) approach as well as its cross-sectionally augmented version (CS-ARDL) for estimation. Therefore, in contrast to the earlier literature on the resource curse, we take into account all three key features of the panel: dynamics, heterogeneity and cross-sectional dependence. Our ...

An investigation of co-movements among the growth rates of the G-7 countries

Early in 2000, after a decade of economic expansion, growth began to slow simultaneously in the large, advanced economies known as the Group of Seven (G-7)--Canada, France, Germany, Italy, Japan, the United Kingdom, and the United States. The general slide in GDP growth fueled speculation that a period was emerging in which broad movements in the economies of the industrialized countries would be more closely linked. Proponents of this view argued that greater trade in goods and financial markets was leading to a greater synchronization of national economies. A rise in the co-movement of GDP ...

Trade Integration, Global Value Chains, and Capital Accumulation

Motivated by increasing trade and fragmentation of production across countries since World War II, we build a dynamic two-country model featuring sequential, multi-stage production and capital accumulation. As trade costs decline over time, global-value-chain (GVC) trade expands across countries, particularly more in the faster growing country, consistent with the empirical pattern. The presence of GVC trade boosts capital accumulation and economic growth and magnifies dynamic gains from trade. At the same time, endogenous capital accumulation shapes comparative advantage across countries, ...

Fewer but Better : Sudden Stops, Firm Entry, and Financial Selection

We incorporate endogenous technical change into a real business cycle small open economy framework to study the productivity costs of sudden stops. In this economy, productivity growth is determined by the entry of new firms and the expansion decisions of incumbent firms. New firms are created after the implementation of business ideas, yet the quality of ideas is heterogeneous and good ideas are scarce. Selection of the most promising ideas gives rise to a trade-off between mass (quantity) and composition (quality) in the entrant cohort. Chilean plant-level data from the sudden stop ...

The Micro and Macro Dynamics of Capital Flows

We study empirically and theoretically the effects of international financial flows on resource allocation. Using the universe of firms in Hungary, we show that removing capital controls lowers firms’ cost of capital and increases household consumption, with the latter playing a dominant role. The consumption channel leads to reallocation of resources toward high expenditure elasticity activities—such as services—promoting both the expansion of incumbents and firm entry. A multi-sector heterogeneous firm model replicates these dynamics. Our model shows that non-homotheticity in ...
