The Economic Costs of Temperature Uncertainty
Luca Bettarelli
,
Davide Furceri
,
Michael Ganslmeier
, and
Marc Schiffbauer
Beyond its environmental damage, climate change is predicted to produce significant economic costs. Combining novel high-frequency geospatial temperature data from satellites with measures of economic activity for the universe of US listed firms, this article examines a potentially important channel through which global warming can lead to economic costs: temperature uncertainty. The results show that temperature uncertainty—by increasing power outages, reducing labor productivity, and increasing the degree of exposure of firms to environmental and non-political risks, as well as economic uncertainty at the firm-level—persistently reduce firms’ investment and sales. This effect varies across firms, with those characterized by tighter financial constraints being disproportionally more affected.

The paper documents the latest extensions of the Bank of Ghana’s Quarterly Projection Model (QPM), used regularly to produce policy analysis and forecasts in support of the Bank’s policy processes. The decomposition of GDP allows to separate the agriculture and oil sectors, driven by exogenous and international developments, from non-agriculture non-oil activities, which are more relevant from the central bank’s perspective of assessing the business cycle position. Inter-sectoral price spillovers and their role in the formation of inflation expectations are explicitly accounted, with important policy implications. Specific model applications – including impulse response functions and simulations of shocks that affect agricultural production, e.g., those caused by climate disruptions; and counterfactual simulations to evaluate recent policy choices – highlight the usefulness of the extended QPM in providing a more detailed account of the economic developments, enhance forecast coverage, and broaden its underlying narrative, thus strengthening the BOG’s forward-looking policy framework.

Geoeconomic Fragmentation and International Diversification Benefits
Tatsushi Okuda
and
Tomohiro Tsuruga
This paper applies the two-country open-economy model with trade in stocks and bonds of Coeurdacier et al. (2010) to quantify the loss of international diversification benefits for major advanced economies, which have a significant presence in international financial markets, under geoeconomic fragmentation. We perform counterfactual simulations under different hypothetical fragmentation scenarios in which these economies are unable to trade with geopolitically distant countries, as measured by voting disagreement on foreign policy issues at the United Nations General Assembly meetings during 2012-2021. The simulation results imply a potentially significant loss of international diversification benefits of financial openness for the considered advanced economies by limiting trading to partner countries that are geopolitical allies with highly synchronized business cycles.

Is Inflation Good for Business? The Firm-Level Impact of Inflation Shocks in the Baltics, 1997-2021
Serhan Cevik
,
Alice Fan
, and
Sadhna Naik
Using a large panel of firm-level data, this paper provides an analysis of how inflation shocks in the Baltics between 1997 and 2021 affected total factor productivity (TFP), gross profitability, and net fixed investment in nonfinancial sectors. First, we find that inflation and inflation volatility had mixed effects on TFP growth, profitability and net fixed investment in the first year as well as over the medium term, albeit at a dissipating rate. Second, focusing on subsamples, we find that inflation shocks had differential effects on large versus small firms. Third, we explore sectoral heterogeneity in how firms responded to inflation shocks and observe significant variation across tradable and non-tradable sectors. Finally, estimates from a state-dependent model suggest that firms’ response to inflation shocks varied with the state of the economy. The results suggest that nonfinancial firms in the Baltics have been agile in adjusting to inflation shocks, possibly by either transferring higher production costs to consumers or substituting inputs. Given the differences in the level and nature of the recent inflation shock and the sample period on which our analysis is based, empirical findings presented in this paper might not necessarily apply to the latest bout of inflation in the Baltics.

The Shifting and Steepening of Phillips Curves During the Pandemic Recovery: International Evidence and Some Theory
Tryggvi Gudmundsson
,
Chris Jackson
, and
Rafael A Portillo
We study the global inflation surge during the pandemic recovery and the implications for aggregate and sectoral Phillips curves. We provide evidence that Phillips curves shifted up and steepened across advanced economies, and that differences in the inflation response across sectors imply the relative price of goods has been pro-cyclical this time around rather than a-cyclical as during previous cycles. We show analytically that these three features emerge endogenously in a two-sector new-Keynesian model when we introduce unbalanced recoveries that run against a supply constraint in the goods sector. A calibrated exercise shows that the resulting changes to the output-inflation relation are quantitatively important and improve the model's ability to replicate the inflation surge during this period.

Monetary Policy Design with Recurrent Climate Shocks
Mr. Vimal V Thakoor
and
Engin Kara
As climate change intensifies, the frequency and severity of climate-induced disasters are expected to escalate. We develop a New Keynesian Dynamic Stochastic General Equilibrium model to analyze the impact of these events on monetary policy. Our model conceptualizes these disasters as left-tail productivity shocks with a quantified likelihood, leading to a skewed distribution of outcomes. This creates a significant trade-off for central banks, balancing increased inflation risks against reduced output. Our results suggest modifying the Taylor rule to give equal weight to responses to both inflation and output growth, indicating a gradual approach to climateexacerbated economic fluctuations.

Financial Heterogeneity, Investment, and Firm Interactions
Yang Liu
Recent literature has shown that corporate indebtedness affects firm-level investment behavior but not necessarily aggregate business cycles. I argue that interactions among heterogeneous firms play an important role in equilibrium. After a downturn, financially unconstrained firms in financially constrained industries significantly increase capital ex-penditure to substitute depressed investment by their financially constrained competitors. The increase in investment, primarily driven by small and medium firms, leads to substantial gains in future sales. Using a new empirical approach, I further show that equilibrium effects are unambiguously countercyclical because the increase in investment by unconstrained firms does not crowd out investment by financially constrained competitors. The “competitive interaction channel” underscored in this paper may play an important role in mitigating the impact of negative shocks in macroeconomic models with financial heterogeneity.

How Costly Will Reining in Inflation Be? It Depends on How Rational We Are
Mr. Jorge A Alvarez
and
Allan Dizioli
We document that past highly inflationary episodes are often characterized by a steeper inflationslack relationship. We show that model-generated data from a standard small Dynamic Stochastic General Equilibrium (DSGE) model can replicate this empirical finding when estimated with different expectation formation processes. When inflation becomes de-anchored and expectations drift, we can observe high inflation even with a mildly positive output gap in response to cost-push shocks. The results imply that we should not use an unconditioned (not controlling for expectations change) Phillips curve estimated in normal times to predict the cost of reining in inflation. Our optimal policy exercises prescribe early monetary policy tightening and then easing in the context of positive output gaps and inflation far above the central bank target.

How Do Adaptive Learning Expectations Rationalize Stronger Monetary Policy Response in Brazil?
Allan Dizioli
and
Hou Wang
This paper estimates a standard Dynamic Stochastic General Equilibrium (DSGE) model that includes a wage and price Phillip's curves with different expectation formation processes for Brazil and the USA. Other than the standard rational expectation process, we also use a limited rationality process, the adaptive learning model. In this context, we show that the separate inclusion of a labor market in the model helps to anchor inflation even in a situation of adaptive expectations, a positive output gap and inflation above target. The estimation results show that the adaptive learning model does a better job in fitting the data in both Brazil and the USA. In addition, the estimation shows that expectations are more backward-looking and started to drift away sooner in 2021 in Brazil than in the USA. We then conduct optimal policy exercises that prescribe early monetary policy tightening in the context of positive output gaps and inflation far above the central bank target.

Understanding Post-COVID Inflation Dynamics
Martin Harding
,
Jesper Lindé
, and
Mathias Trabandt
We propose a macroeconomic model with a nonlinear Phillips curve that has a flat slope when inflationary pressures are subdued and steepens when inflationary pressures are elevated. The nonlinear Phillips curve in our model arises due to a quasi-kinked demand schedule for goods produced by firms. Our model can jointly account for the modest decline in inflation during the Great Recession and the surge in inflation during the Post-Covid period. Because our model implies a stronger transmission of shocks when inflation is high, it generates conditional heteroskedasticity in inflation and inflation risk. Hence, our model can generate more sizeable inflation surges due to cost-push and demand shocks than a standard linearized model. Finally, our model implies that the central bank faces a more severe trade-off between inflation and output stabilization when inflation is high.
