We demonstrate that durable MFN tariff elimination affects trade patterns through severallayers, which generates non-linear impacts. First, complete tariff elimination results in a largeadditional trade gains over and above tariff reductions. Second, commitment to durable tariffelimination,...

The enormous global demand for smartphones in recent years has created a new global tech cycle. In 2016 alone, global smartphone sales reached close to 1.5 billion, one for every fifth person on earth. In turn, this has engendered complex and evolving supply chains across Asia. We show that the...

Global smartphone sales may have peaked. After reaching nearly 1.5 billion units in 2016, global smartphone sales have since declined, contributing negatively to world trade in 2019 and suggesting that the global market may now be saturated. This paper develops a simple model to forecast...

We provide systematic evidence on cartels’ characteristics, using novel data on cases investigated by the French Competition Authority. These practices are widely spread across sectors and cartel members are typically among the top firms in their industries. In a model with heterogeneous firms...

Debt levels, both private and public, were already at record highs before the Covid-19 pandemic, and surged further in 2020. The high indebteness raises concerns whether it will undermine future growth prospects. This paper contributes to the ongoing debate by examining what happens to economic...

A growing literature estimates the macroeconomic effect of weather using variations in annual country-level averages of temperature and precipitation. However, averages may not reveal the effects of extreme events that occur at a higher time frequency or higher spatial resolution. To address...

In terms of size, the net income balance (IB) is comparable to the trade balance (TB) for many countries. Yet the role of the IB in mitigating external vulnerabilities or complicating external adjustment remains underexplored. This paper studies the role of the IB in stabilizing or destabilizing...

This paper investigates the heterogenous effects of budget balance rules on fiscal policy in a large sample of countries. To derive country-specific treatment effects of fiscal rules and conduct inference, we use a Synthetic Difference-in-Differences Method. Our results indicate that countries...

Resource-rich countries face large and persistent shocks, especially coming from volatile commodity prices. Given the severity of the shocks, it would be expected that these countries adopt countercyclical fiscal policies to help shield the domestic economy. Taking advantage of a new dataset...

This paper develops a structural macroeconometric model of the world economy,disaggregated into forty national economies. This panel dynamic stochastic generalequilibrium model features a range of nominal and real rigidities, extensivemacrofinancial linkages, and diverse spillover transmission...
