Is High Debt Constraining Monetary Policy? Evidence from Inflation Expectations
Description: This paper examines whether high government debt levels pose a challenge to containing inflation. It does so by assessing the impact of government debt surprises on inflation expectations in advanced- and emerging market economies. It finds that debt surprises raise long-term inflation expectations in emerging market economies in a persistent way, but not in advanced economies. The effects are stronger when initial debt levels are already high, when inflation levels are initially high, and when debt dollarization is significant. By contrast, debt surprises have only modest effects in economies with inflation targeting regimes. Increased debt levels may complicate the fight against inflation in emerging market economies with high and dollarized debt levels, and weaker monetary policy frameworks.

Beyond the Annual Averages: Impact of Seasonal Temperature on Employment Growth in US Counties
Description: Using quarterly temperature and employment data between 1990 and 2021, this paper uncovers nuanced evidence on the impact of seasonal temperature within US counties: higher winter temperature increases private sector employment growth while higher summer temperature decreases it. The impacts of higher temperature in mild seasons, fall and spring, are statistically insignificant. Moreover, the negative impact of higher summer temperature persists while the positive impact of higher temperature in the winter is more short-lived. The negative effects of a hotter summer are pervasive and persistent in many sectors: most significantly in “Construction” and “Leisure and Hospitality” but also in “Trade, Transport, and Utilities” and “Financial Activities.” In contrast, the positive effects of a warmer winter are less pervasive. The employment effect of a hotter summer has been more severe in recent decades.

Decomposing Climate Risks in Stock Markets
Description: Climate change poses an unprecedented challenge to the world economy and the global financial system. This paper sets out to understand and quantify the impact of climate mitigation, with a focus on climate-related news, which represents an important information source that investors use to revise their subjective assessments of climate risks. Using full-text data from Financial Times from January 2005 to March 2022, we develop machine learning-based indicators to measure risks from climate mitigation, and the direction of the risk is identified through manual labels. The documented risk premium indicates that climate mitigation news has been partially priced in the Canadian stock market. More specifically, stock prices react positively to market-wide climate-favorable news but they do not react negatively to climate-unfavorable news. The results are robust to different model specifications and across equity markets.

The Impact of Climate Policy on Oil and Gas Investment: Evidence from Firm-Level Data
Description: Using a text-based firm-level measure of climate policy exposure, we show that climate policies have led to a global decline of 6.5 percent in investment among publicly traded oil and gas companies between 2015 and 2019, with European companies experiencing the most significant impact. Similarly, climate policy uncertainty has also had a negative impact. Results support the Neoclassical investment model, which predicts a pre-emptive cut in investment in reaction to downward shifts in prospective demand, in contrast with the “green paradox” that predicts an increase in current investment to shift production toward the present.

Unpleasant Surprises? Elections and Tax News Shocks
Description: Unanticipated changes in tax policy are likely to have different macroeconomic effects compared to anticipated changes due to several mechanisms, including fiscal foresight and policy uncertainty. It is therefore important to understand what drives such policy surprises. We explore the nature of unanticipated tax policy changes by focusing on a political economy determinant of those events, namely the timing of elections. Using monthly data for 22 advanced economies and emerging markets over the period 1990-2018, we show that implementation lags tend to be significantly longer for tax policy change announcements that are made during the pre-election periods, thereby leading to a lower likelihood of “tax news shocks”. We also find that implementation lags become much shorter for tax policy changes that are announced in the aftermath of elections, generating more frequent tax news shocks. This pattern remains similar for different tax measures or types of taxes. The findings are robust to a number of checks, including alternative definitions of tax news shocks, or to controlling for various economic and institutional factors.

The Macroeconomic Returns of Investment in Resilience to Natural Disasters under Climate Change: A DSGE Approach
Description: This paper presents a Markov switching dynamic stochastic general equilibrium model designed to evaluate the macroeconomic return of adaptation investment to natural disasters (NDs) and the impact of climate change. While the model follows the existing literature in assuming that NDs destroy a share of the public and private capital stocks and a government that can invest in adaptation at an additional cost, it adds several features that are key to the analysis, both in the near (transition) and long (steady state) terms. Those include incomplete markets, financial frictions with collateral constraints, foreign remittances, full menu of tax and government spending instruments, and endogenous climate risk premium. The model is calibrated to the case of Dominica. It finds that NDs have large and persistent negative effects on output and public finances. It also shows that adaptation investment has large returns in terms of private investment, employment, output and tax revenue in the long term, especially under climate change.

A Note of Caution on the Relation Between Money Growth and Inflation
Description: We assess the bivariate relation between money growth and inflation in the euro area and the United States using hybrid time-varying parameter Bayesian VAR models. Model selection based on marginal likelihoods suggests that the relation is statistically unstable across time in both regions. The effect of money growth on inflation weakened notably after the 1980s before strengthening after 2020. There is evidence that this time variation is related to the pace of price changes, as we find that the maximum impact of money growth on inflation is increasing in the trend level of inflation. These results caution against asserting a simple, time-invariant relationship when modeling the joint dynamics of monetary aggregates and consumer prices.

Migration, Search and Skill Heterogeneity
Description: Cross-border migration can act as an important adjustment mechanism to country-specific shocks. Yet, depending on who moves, it can have unintended consequences for business cycle stability. This paper argues that the skill composition of migration plays a critical role. When migration flows become more concentrated in skilled labor an important trade-off arises. On the one hand, migration releases unemployment pressures for the origin countries. On the other hand, it generates negative compositional effects (the so-called “brain drain” effects) and skill imbalances, which reduce supply capacity in origin countries. This paper analyses quantitatively the impact of cyclical migration in an open-economy Dynamic Stochastic General Equilibrium (DSGE) model with endogenous migration flows, trade linkages, search and matching frictions, and skill heterogeneity. I apply this framework to the case of the Greek emigration wave following the European Debt Crisis. What I find is that emigration flows implied strong negative effects for capital formation, leading to more than a 15 percentage point drop in investment. Rather than stabilizing the Greek business cycle, labor mobility led to a deeper and more protracted recession.

Euro Area Inflation after the Pandemic and Energy Shock: Import Prices, Profits and Wages
Description: We document the importance of import prices and domestic profits as a counterpart to the recent increase in euro area inflation. Through a novel consumption deflator decomposition, we show that import prices account for 40 percent of the average change in the consumption deflator over 2022Q1 – 2023Q1, while domestic profits account for 45 percent. The increase in nominal profits was largest in sectors benefiting from increasing international commodity prices and those exposed to recent supply-demand mismatches. While the results show that firms have passed on more than the nominal cost shock, and have fared relatively better than workers, the limited available data does not point to a widespread increase in markups. Looking ahead, assuming nominal wage growth of around 4.5 percent over 2023-24 – slightly below the level seen in Q1 2023 – and broadly unchanged productivity, a normalization of the profit share to the average level over 2015-19 will be necessary to achieve a convergence of inflation to target over the next two years. Monetary policy will thus need to remain restrictive to anchor expectations and maintain subdued demand such that workers and firms settle on relative price setting that is consistent with disinflation.

External Shocks, Policies, and Tail-Shifts in Real Exchange Rates
Description: We use panel quantile regressions to study extreme (rather than average) movements in the distribution of the real effective exchange rate (REER) of small open economies. We document that global uncertainty (VIX) and global financial conditions (U.S. monetary policy) shocks have a strong impact on the distribution of the REER changes, with larger impacts in the tails of the distribution, and especially in economies with shallower FX markets, lower central bank credibility, and higher credit risk (i.e., weaker macro fundamentals). Foreign exchange intervention (FXI) partially offsets the impact of these shocks, especially in the left tail (large depreciations) and particularly in economies with weaker fundamentals but, more importantly, when FXI is used sporadically. Thus, our results highlight the importance of deepening FX markets, improving central bank credibility, and strengthening macro fundamentals against the potential dynamic trade-offs of overreliance on a policy that would exacerbate the previously mentioned frictions. While our results point to low effectiveness of capital flow management in preventing large REER movements, they seem to enable more impactful foreign exchange intervention in the immediate aftermath of shocks.
