 Some important topics in financial economics have received partial attention, including the Modigliani-Miller capital structure irrelevance theorem (Hindriks 2008), the efficient market hypothesis (Collier 2011), the Black-Scholes option pricing model (Weatherall 2017), portfolio theory (Walsh 2015), financial equilibrium models (Farmer &amp; Geanakoplos 2009), the concept of money (Mäki 1997), and behavioral finance (Brav, Heaton, &amp; Rosenberg 2004), even though most of the debate still occurs among economists interested in methodology rather than among philosophers. A host of topics remain to be investigated, however: the concept of Value at Risk (VaR) (and more broadly the concept of financial risk), the capital asset pricing model (CAPM), the Gaussian copula, random walks, financial derivatives, event studies, forecasting (and big data), volatility, animal spirits, cost of capital, the various financial ratios, the concept of insolvency, and neurofinance, all stand in need of more sustained attention from philosophers.
