Abstract: In this paper, we investigate the asymptotic behavior of the Bachelier implied volatility tails, extending the large-strike results established for the Black–Scholes implied volatility. By exploiting the theory of regular variation, we derive explicit expressions for the Bachelier implied volatility in the wings of ...more »

Abstract: In McMahon et al. (2024) the authors demonstrated the effectiveness of a hybrid quantum solver in improving the liquidity efficiency of Canada’s high-value payments system (HVPS), altering the payment queue in order to minimize liquidity requirements. In this work, we apply a similar technique ...more »

Abstract: We show that the parameters of a broad class of portfolio-balance models can be recovered from estimates of Gaussian dynamic term structure models (GDTSMs) using a two-step estimator that bypasses the fixed-point problem that characterizes portfolio balance models. Specifically, we develop a novel canonical ...more »

Abstract: Theory suggests inflation risk premia are positive when supply shocks are expected to dominate demand shocks and negative otherwise. We measure these beliefs using demand and supply narratives derived from inflation news via Causality Extraction, which identifies causal relations between inflation and its drivers. ...more »

Abstract: Firms’ hurdle rates exceed their financial cost of capital. This gap varies across firms and has widened in the aggregate. In our Schumpeterian model, two frictions drive this gap: firm decision-makers require an innovator’s risk premium for undiversifiable innovation risk, and innovation profits are ...more »

Abstract: This paper studies the financial-market transmission of the April 2025 U.S. tariff announcements, with a particular focus on the unusual combination of dollar depreciation and rising long-term U.S. Treasury yields. We ask whether the market reaction can be understood as the propagation of a ...more »

Bank of England, Working paper n° 1,207

2026
Abstract: Does the price of synthetic dollar funding depend on which dealer intermediates the trade? We answer this question by comparing FX forwards in the same dollar currency pair, half-hour, and maturity bucket, which removes the common forward curve and isolates dealer-specific pricing. These dealer-specific ...more »

Abstract: Using fine-grained data on 465,000 Florida home sales over twelve years and semiparametric machine learning methods, we examine how home prices respond to weather-related risk factors. After controlling for geography, home characteristics, and transaction features, we find that home prices are negatively related to ...more »

Abstract: We introduce the Financial Vulnerability Index (FVI), a novel indicator of financial vulnerabilities in the U.S. Unlike financial condition indices, which measure current credit market conditions and spike during periods of financial turmoil, the FVI displays the gradual build-up of structural financial weaknesses and ...more »
