- This paper presents DSGE Nash, a toolkit to solve for pure strategy Nash equilibria of global games in macro models. Although primarily designed to solve for Nash equilibria in DSGE models, the toolkit encompasses a broad range of options including solutions up to the third order, multiple players/strategies, the use of user-de_ned objective functions and the possibility of matching empirical moments and IRFs. When only one player is selected, the problem is re-framed as a standard optimal policy problem. We apply the algorithm to an open-economy model where a commodity importing country and a monopolistic commodity producer compete on the commodities market with limits to entrance. If the commodity price becomes relevant in production, the central bank in the commodity importing economy deviates from the _rst best policy to act strategically. In particular, the monetary authority tolerates relatively higher commodity price volatility to ease barriers to entry in commodity production and to limit the market power of the dominant exporter.

- In this paper we explore the cross-country implications of climate-related mitigation policies. Specifically, we set up a two-country, two-sector (brown vs green) DSGE model with negative production externalities stemming from carbon-dioxide emissions. We estimate the model using US and euro area data and we characterize welfare-enhancing equilibria under alternative containment policies. Three main policy implications emerge: i) fiscal policy should focus on reducing emissions by levying taxes on polluting production activities; ii) monetary policy should look through environmental objectives while standing ready to support the economy when the costs of the environmental transition materialize; iii) international cooperation is crucial to obtain a Pareto improvement under the proposed policies. We finally find that the objective of reducing emissions by 50%, which is compatible with the Paris agreement's goal of limiting global warming to below 2 degrees Celsius with respect to pre-industrial levels, would not be attainable in absence of international cooperation even with the support of monetary policy.

- This paper proposes an approach to estimate the impact of adverse climatic events on the profitability of small European banks (LSIs). By considering river flooding phenomena, we construct a unique database matching the information on location, frequency and severity of floods with the location and balance sheet data of institutions mainly operating in the areas where they are headquartered (territorial LSIs). We compare the performance of territorial LSIs across regions at low and high flooding risk and test for the “core lending channel” hypothesis, whereby lending to the real economy is a catalyst of physical risks. Results show that an adverse event dropping loans to households and non-financial corporations by one percentage point (pp) of total assets entails a decrease in the Return on Assets (ROA) of territorial LSIs in riskier areas by 0.01pps (~3.1%). Moreover, if all territorial LSIs were located in riskier areas, one bank out of two would report an average ROA between 0.0001 and 0.52 percentage points lower than what observed.

- In this paper, we apply textual analysis and machine learning algorithms to construct an index capturing trade tensions between US and China. Our indicator matches well-known events in the US-China trade dispute and is exogenous to the developments on global financial markets. By means of local projection methods, we show that US markets are largely unaffected by rising trade tensions, with the exception of those firms that are more exposed to China, while the same shock negatively affects stock market indices in EMEs and China. Higher trade tensions also entail: i) an appreciation of the US dollar; ii) a depreciation of EMEs currencies; iii) muted changes in safe haven currencies; iv) portfolio re-balancing between stocks and bonds in the EMEs. We also show that trade tensions account for around 15% of the variance of Chinese stocks while their contribution is muted for US markets. These findings suggest that the US-China trade tensions are interpreted as a negative demand shock for the Chinese economy rather than as a global risk shock.

- This paper quantifies the economic influence that shocks to EMU cohesion, which in turn reflect the incomplete nature of the monetary union, have on the rest of the world. Disentangling euro area stress shocks and global risk aversion shocks based on a combination of sign, magnitude and narrative restrictions in a daily Structural Vector Autoregression (VAR) model with financial variables. We find that the effects of euro area stress shocks are significant not only for the euro area but also for the rest of the world. Notably, an increase in euro area stress entails a slowdown of economic activity in the rest of the world, as well as a fall in imports/exports of both the euro area and the rest of the world. A decrease in euro area stress has somewhat more widespread beneficial effects on both economic performance and global trade activity.
