Spillover dynamics effects between risk-neutral equity and treasury volatilities
(Springer, 2022) González Urteaga, Ana; Nieto, Belén; Rubio, Gonzalo; Enpresen Kudeaketa; Institute for Advanced Research in Business and Economics - INARBE; Gestión de Empresas; Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa
Macro-finance asset pricing models provide a rationale for connectedness dynamics between equity and Treasury risk-neutral volatilities. In this paper, we study the total and directional connectedness, in the sense of spillover effects, between risk-neutral volatilities from the equity and Treasury markets. In addition, we analyze the economic and monetary drivers of connectedness dynamics. Most of the time, but especially during bad economic times, we find significant net spillovers from Treasury to equity risk-neutral volatility. The spillover channel between risk-neutral volatilities arises mainly through the government fixed income market.

A forecasting analysis of risk‐neutral equity and Treasury volatilities
(Wiley, 2019) González Urteaga, Ana; Nieto, Belén; Rubio Irigoyen, Gonzalo; Gestión de Empresas; Enpresen Kudeaketa; Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa
This paper employs equity (VIX) and Treasury (MOVE) risk‐neutral volatilities to assess their relative forecasting performance with respect to future real activity, stock and Treasury excess returns, and aggregate risk factors. The in‐sample evidence suggests that the square of VIX tends to dominate the square of MOVE. Out‐of‐sample predictive analysis, performed as a horse race between equity and Treasury risk‐neutral volatilities, shows that, contrary to earlier results, the square of VIX and MOVE tend to complement each other.

Extracting expected stock risk premia from option prices and the information contained in non-parametric-out-of-sample stochastic discount factors
(Routledge, 2020) González Urteaga, Ana; Nieto, Belén; Rubio Irigoyen, Gonzalo; Enpresen Kudeaketa; Institute for Advanced Research in Business and Economics - INARBE; Gestión de Empresas; Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa
This paper analyzes the factor structure and cross-sectional variability of a set of expected excess returns extracted from option prices and a non-parametric and out-of-sample stochastic discount factor. We argue that the existing potential segmentation between the equity and option markets makes it advisable to avoid using only option prices to extract expected equity risk premia. This set of expected risk premia significantly forecasts future realized returns, and the first two principal components explain 94.1% of the variability of expected returns. A multi-factor model with the market, quality, funding illiquidity, the default premium and the market-wide variance risk premium as factors significantly explains the cross-sectional variability of expected excess returns. The (asymptotically) different from zero adjusted cross-sectional R-squared statistic is 83.6%.

Do sovereign ratings cause instability in cross-border emerging CDS markets?
(Elsevier, 2021) Ballester Miquel, Laura; González Urteaga, Ana; Institute for Advanced Research in Business and Economics - INARBE
We analyse the cross-border transmission effect of credit ratings on sovereign CDSs covering a broad sample of emerging countries during the period 2004 to 2015. This study differentiates between the spillover and competition effects between and within geographical areas of emerging countries. We find substantial evidence of cross-border effects with asymmetric responses to upgrades and downgrades. The market reaction differs across regions, reflecting how the international and local impact of rating events are due to different types of effects. At the international portfolio level, the competitive effect is dominant over the spillover effect. Negative events in Asia benefit Africa (which is also negatively affected by upgrades in Asia) and Middle East, the latter transmitting in turn to Asia with the same competitive effect. However, some spillover effects are also found both at the portfolio and intra-portfolio levels. The ones associated with downgrades are especially sensitive. In these cases, we identify the particular emerging economies that contribute to an increase in financial instability and to regional spillover effects.

Further empirical evidence on stochastic volatility models with jumps in returns
(Elsevier España, S.L., 2012) González Urteaga, Ana; Gestión de Empresas; Enpresen Kudeaketa
Using the Efficient Method of Moments we estimate a continuous time diffusion for the stochastic volatility of some international stock market indices that allows for possible jumps in returns. These jumps are needed for a sensible characterization of the dynamics of the distribution of returns, even under stochastic volatility. Although the stochastic volatility model with jumps in returns tends to exaggerate the negative skewness relative to the sample moments, the inclusion of jumps strongly improves the ability of the model to replicate sample kurtosis. This contrasts with the failure of the pure stochastic volatility model in generating high enough kurtosis. Our results extend the limited available evidence from the U.S. market to several European stock market indices.

Bank fragility and contagion: evidence from the bank CDS market
(Elsevier, 2016) Ballester Miquel, Laura; Casu, Barbara; González Urteaga, Ana; Gestión de Empresas; Enpresen Kudeaketa
Understanding how contagion works among financial institutions is a top priority for regulators and policy makers who aim to foster financial stability and to prevent financial crises. Using bank credit default swap (CDS) data, we provide a framework for the evaluation of contagion among banks in different countries and regions during a period of prolonged financial distress. We measure contagion in terms of return spillovers, following a Generalized VAR (GVAR) approach. In addition, we propose an innovative framework to distinguish between two types of contagion: systematic (linked to global factors), and idiosyncratic (linked to bank specific factors). We find evidence of both types of contagion, although the spillover dynamics changed over time. Our measure of systematic contagion is always greater than the idiosyncratic component, thus highlighting the importance of common factors in the propagation of risk spillovers. This indicates that international linkages among banking markets are central to the transmission of shocks.

A systematic review of sovereign connectedness on emerging economies
(Elsevier, 2019) Ballester Miquel, Laura; Díaz Mendoza, Ana Carmen; González Urteaga, Ana; Enpresen Kudeaketa; Institute for Advanced Research in Business and Economics - INARBE; Gestión de Empresas
This article systematically reviews the academic literature on emerging market contagion in order to summarize what we have learnt about the transmission channels existing in these countries. Given the large body of academic research focused on this topic, we especially direct our attention to the strand of the literature that defines and empirically analyses this topic as the significant increase in the cross-market correlations between asset returns during crisis periods or when a shock occurs. The survey covers the findings on financial contagion in the stock, bond, exchange and credit default swap markets during a large period that covers several crises that have characterized the related literature, such as the currency crises of the 1990s, the global financial crisis and the Eurozone debt crisis. Finally, new topics are identified, serving as an outline for future research.

Lagged accuracy in credit-risk measures
(Elsevier, 2022) Abinzano Guillén, María Isabel; González Urteaga, Ana; Muga Caperos, Luis Fernando; Sánchez Alegría, Santiago; Institute for Advanced Research in Business and Economics - INARBE
This paper analyzes the magnitude (accuracy) and length (time) of the lag in the incorporation of new information in different measures of credit risk. The results, for US firms, show a lag for Altman’s Z accounting measure and credit rating. In contrast, market-based credit-risk measures such as CDSs and the Black-Scholes-Merton model show no lag. This paper also analyzes the determinants of the lags found showing the importance of the informativeness of CDSs in reducing the lag for all types of default events, and a negative relationship between accounting manipulation and the lag of Altman’s Z for severe default events.

The joint cross-sectional variation of equity returns and volatilities
(Elsevier, 2017) González Urteaga, Ana; Rubio Irigoyen, Gonzalo; Gestión de Empresas; Enpresen Kudeaketa
This paper analyzes the determinants of the simultaneous cross-sectional variation of return and volatility risk premia. Independently of the model specification employed, the estimated risk premium associated with the default premium beta is always positive and statistically different from zero. Moreover, the risk premium of the market volatility risk premium beta is negative and statistically significant. However, both risk factors are priced economically and statistically differently in the volatility and return segments of the market. On average, common factors in both segments explain 90% of the variability of volatility risk premium portfolios, but only 65% of the variability of equity return portfolios.

Volatility spillovers in the European bank CDS market
(Elsevier, 2015) Alemany, Aida; Ballester Miquel, Laura; González Urteaga, Ana; Gestión de Empresas; Enpresen Kudeaketa
From the 2007 subprime crisis to the recent Eurozone debt crisis,the banking industry has experienced terrible financial instabilitywith increasing volatility levels of bank default probability. UsingEuropean CDS spreads data from January 2006 to March 2013, thispaper sheds light on the impact of three recent significant events ofcredit risk volatility transmission between, firstly, Eurozone andnon-Eurozone banks, and then between distressed peripheral andcore countries inside the Eurozone. We employ an asymmetricmultivariate BEKK model to measure cross-market volatility spil-lovers. We find that both recent crises are distinct episodes. Theglobal financial crisis that originated outside Europe is character-ized by unidirectional volatility spillovers in credit risk from insideto outside the Eurozone. By contrast, the Eurozone debt crisis isrevealed to be local in nature with the euro as the key element,suggesting a financial market fragmentation within the Eurozonebetween distressed peripheral and non-distressed core Eurozonecountries, whereas retaining the local currency has acted as afirewall.
