Climate growth at risk in the global south (with C. Giraldo, I. Giraldo and J. Gomez), Energy Economics 149, 108790, 2025
We study climate uncertainty shocks in Latin America & the Caribbean using new volatility, skewness, and kurtosis indicators from daily temperatures.
Found only (positive) skewness worsens low-growth periods; hence increasing growth vulnerability.
Urged inclusion of climate skewness in models to capture vulnerable growth risks.
Sovereign debt cost and economic complexity (with O. Valencia and J. Gómez) Journal of International Financial Markets, Institutions & Money 99: 102121, 2025.
Economic complexity reduces 10-year yield spreads by about 61 basis points.
Short-term yields (<3 years) show no significant impact from economic complexity.
Economic complexity is a top predictor of sovereign yield spreads.
Asymmetric Sovereign Risk: Implications for Climate Change Preparation (with O. Valencia and J. Gómez), World Development, 188, 106908, 2025.
Effects of climate change vulnerability and preparedness on the cost of debt across countries with varying baseline levels of sovereign risk (specially for short-term debt) are highly asymmetric.
Climate vulnerability currently has a stronger influence on sovereign risk than the occurrence of actual disasters.
Investment in Intangible Assets and Economic Complexity, Research Policy, 54, 105133, 2025.
Economic complexity (trade) is largely explained by investment in R&D and Training in the manufacturing sector.
Policy should focus on intangible assets rather than on (solely) selecting specific products for trading.
Common Factors in the Profitability of Energy Firms (with Joaqui O., and Manotas, D.) Energy Journal 46(2), 171-200, 2025
We identify three latent profitability factors for 1,347 global energy firms.
These factors are related to global market conditions.
We find oil and gas firms sensitive to interest rates and fuel prices, renewables and uranium to exchange rates
Vulnerable Funding in the Global Economy (with H.Chulia and Ignacio Garrón) Journal of Banking & Finance 169, 107314, 2024.
Similar to "vulnerable growth" there is "vulnerable funding"
Vulnerable funding acts as an intermediary from financial conditions in the US to growth in the rest of the world
Macro-prudential policies at this intermediate step are fundamental
Weather conditions, climate change, and the price of electricity (with S. Mosquera and O. Joaqui), Energy Economics 137, 107789, 2024.
Weather shocks impact heterogeneously European electricity markets
We provide a tool to monitoring the dissimilar effects over time and according to the size of the shock
Daily growth at risk: financial or real drivers? The answer is not always the same (with Chuliá H., Garrón, I. ) International Journal of Forecasting 40, 762-776, 2024
Financial and macroeconomic variables predict the lowest quantiles of GDP growth
Predicting-power of both variables changes according to the crisis (i.e. the nature of the shock, GFC vs. Covid)
Financial integration and banking stability: A post-Global Crisis assessment (with C. Giraldo, I. Giraldo and J. Gomez), Economic Modelling 139, 106835, 2024
Financial integration is beneficial for financial stability, at least considering the period post-GFC
Vulnerability of European electricity markets: A quantile connectedness approach (with Chuliá, H., Klein, T., Mendoza, J. A). Energy Policy 184, 113862, 2024
Energy markets design (i.e. in Europe, marginal price) generates large asymmetries in the transmission of fuel price shocks to electricity markets
This should be addressed. Extreme transmission (documented here) put at risk the operation of wholesale markets
Does economic complexity reduce the probability of a fiscal crisis? (with Gomez-Gonzalez J.E., Valencia, O.) World Development 168, 106250, 2023
Economic complexity (EC) reduces the likelihood of fiscal crises
Policy makers should focus on EC as a way to construct more resilient economies
Systemic political risk (with Chuliá H., Estevez, M.) Economic Modelling 125, 106375, 2023.
The perception of corporate exposure to political risk propagates across firms (it is not purely idiosyncratic)
It's a good idea to view the firms' network as a system and to monitor systemic risk
In our work, we demonstrate how this can be done
Cash flow investment, external funding and the energy transition: Evidence from large US energy firms (with Restrepo, N., and ). Energy Policy 181, 113720, 2023
We document a positive relationship between investment and cash flow for green energy firms, which resemble financially constrained firms.
We show that while brown energy firms channel higher cash flow toward dividends and equity repurchases, green and constrained firms prioritize debt repayment and investment, highlighting the need for stronger financial sources to support the energy transition.
Nonlinear market liquidity: An empirical examination (with Chuliá, H., Mosquera, S.) International Review of Financial Analysis 87, 102532, 2023
Market liquidity is extremely non-linear, for most stocks is irrelevant, but for a few is determinant
It shouldn't be treated as a linear- or linearizable- factor
European stock market volatility connectedness: The role of country and sector membership (with Guillen, M., Vidal, X.) Journal of International Financial Markets, Institutions & Money 82, 101696, 2023
The country where a stock is listed is more relevant than its sector (for risks analysis)
There are considerable asymmetries between sectors and countries
Analyzing individual firms offers far better insights than relying on aggregate country-indexes
Spillovers beyond the variance: exploring the higher order risk linkages between commodity markets and global financial markets (with Gomez-Gonzalez J.E., Hirs-Garzon J.) Journal of Commodity Markets 28, 100258, 2022
The definition of "risk" is fundamental for analyzing risk transmission across commodity markets
Different implications if we use volatility, semi-volatility, skewness, kurtosis , etc., as our poxy for risk
Assessing the relationship between electricity and natural gas prices in European markets in times of distress (with Mosquera-López, S. and Arenas, O.). Energy Policy 166, 113018, 2022
We identify Denmark, Finland, Sweden, and Germany as the most vulnerable to natural gas price shocks during the market distress episodes of 2021-2022.
This, despite their small but non-zero shares of natural gas in electricity generation.
We also show that higher market integration reduces vulnerability.
Analyzing the nonlinear pricing of liquidity risk according to the market state (with Chuliá, H., Koser, C.) International Review of Financial Analysis 38, 101515, 2021
We investigate how systemic liquidity affects asset prices across market states.
We find equity returns’ exposure to liquidity risk depends on whether markets are in particularly good or bad states.
We show liquidity is irrelevant in normal times, with search-for-yield and flight-to-liquidity explaining the extremes.
Volatility spillovers in energy markets (with Chuliá H, Furió D.) Energy Journal 40(3), 173-198, 2019
We measure the links between 17 energy market price series, revealing volatility spillovers within and across sectors.
Found Germany, France, and the Netherlands have the most integrated European electricity markets, with the Dutch TTF emerging as a likely benchmark for European natural gas.
Provided evidence that natural gas may be replacing crude oil as the global benchmark for energy commodities.
Currency downside risk, liquidity, and financial stability (with Chuliá, H., Fernández, J.) Journal of International Money and Finance 89: 83-102, 2018
FX markets are very asymmetric, a devaluation and a revaluation are far from similar phenomena
When measuring risk-transmission in FX markets, always use an asymmetric risk proxy (i.e. quantiles)
Uncovering the nonlinear predictive causality between natural gas and electricity prices (with Guillén M., Mosquera, S.) Energy Economics 74: 904-916, 2018
Natural gas impacts electricity markets in all US hubs asymmetrically
In times of scarcity, the shocks transit much stronger, which could destabilize the market
Market design (i.e. marginal price) should be revisited and improved
Measuring uncertainty in the stock market (with Chuliá, H., Guillén, M.) International Review of Economics and Finance 48: 18-33, 2017.
A new daily macro-financial uncertainty measure is provided
Our measure virtually replicates IRFs from previous, more complex methods
Our measure reduces information and computational costs
Spillovers from the US to Latin American and G7 stock markets: A VAR-quantile analysis (with Chuliá, H., Guillén, M.) Emerging Markets Review 31:32-46, 2017.
Spillovers from the US to the rest of the G7 are highly asymmetric
Diversification benefits are considerable reduced during high-risk episodes
Uncertainty, systemic shocks and the global banking sector: has the crisis modified their relationship? (with Chuliá, H., Guillén, M.) Journal of International Financial Markets, Institutions & Money 50: 52-68, 2017.
Risk propagation has remained stable over the last decade
Equity market uncertainty is a major systemic-risk factor for the global banking system.
Impact of US uncertainties on emerging and mature markets: Evidence from a quantile-vector autoregressive approach (with Chuliá, H., Gupta, R. and Wohar, M.) Journal of International Financial Markets, Institutions & Money 48: 178-91, 2017.
We study how US policy and equity market uncertainties affect domestic and global stock returns.
During financial distress, uncertainty shocks lower stock returns across markets.
