To replicate or extend it, read the full source at the [original](https://doi.org/10.1016/j.jbankfin.2025.107597). ## TL;DR Avramov, Cheng, and Tarelli develop a noisy rational-expectations equilibrium model of active fund management in which agents have heterogeneous ESG preferences and can acquire costly private signals about asset payoffs. Building on the information acquisition framework of Grossman and Stiglitz (1980), the model shows that in equilibrium ESG-perceptive fund managers intensify information acquisition for assets that deviate from ESG neutrality, especially green (high-ESG) assets, which broadens the scope of active management. The enhanced signal precision lowers the posterior variance of green asset payoffs, reducing their implied cost of equity capital (ICC) and making the ESG-ICC relation negative and concave. The paper relates to the evidence in Hartzmark and Sussman (2019) that sustainability ratings drive fund flows, and tests the equilibrium ESG-return predictions of Pastor, Stambaugh & Taylor (2021) by documenting a concave (not merely linear) ESG-ICC relation amplified by an information channel absent from prior theory. Applied to monthly data on U.S. equity mutual funds and common stocks from 2007 to 2021, the model predictions are confirmed: stocks held by funds with heterogeneous ESG preferences display higher price informativeness, green stocks held by green funds have significantly lower ICC than brown stocks, and green funds earn significantly positive abnormal returns when investing in green stocks. ## Core results Magnitudes and significance are as reported; `\*`/`\*\*`/`\*\*\*` = 10%/5%/1%.

Information acquisition driven by ESG motives not only provides capital to green firms at a lower cost but also improves overall financial market efficiency by incorporating more private information into equilibrium prices. The concave ESG-ICC relation and the asymmetric performance of green and brown funds in their preferred ESG domains provide corroborating evidence for the model's information channel. ## Theory / model The economy has $$N$$ risky assets. For $$i \in \{1, \ldots, N-1\}$$, asset payoffs load on both idiosyncratic and an aggregate risk factor; the $$N$$th asset is a pure aggregate asset (p. 3, Eq. 1): $$ \begin{cases} f_i = \mu_i + b_i z_N + z_i, & i \in \{1, \ldots, N-1\} \\ f_N = \mu_N + z_N \end{cases} \tag{1} $$ where $$\mu_i$$ is the expected payoff, $$b_i$$ is the asset's exposure to the aggregate factor $$z_N$$, and $$z_i \sim \mathcal{N}(0, \sigma_i)$$ is an idiosyncratic shock. Shocks are uncorrelated. The risk factor supply for asset $$i$$ is $$\bar{x}_i + x_i$$ where $$\bar{x}_i$$ is mean supply and $$x_i \sim \mathcal{N}(0, \sigma_N^2(1+b_i^2))$$ is a random component. Random supply introduces noise that prevents prices from fully revealing private signals. Agents are indexed by $$j$$ on a continuum. Each agent-asset pair $$(i,j)$$ can acquire a private signal (p. 3, Eq. 2): $$ \eta_{ij} = z_i + \varepsilon_{ij}, \qquad \varepsilon_{ij} \sim \mathcal{N}\!\left(0, S_{ij}^{-1}\right) \tag{2} $$ where $$S_{ij} \geq 0$$ is the signal precision chosen by agent $$j$$ at cost $$c_{ij}(S_{ij})$$, a continuous, increasing, convex function with $$c_{ij}(0)=0$$. Agents are heterogeneous in their cost functions (stock-picking skill) and in their ESG preference parameter $$\delta_j \geq 0$$ (nonnegative for all agents, strictly positive for ESG-perceptive agents). In period 2, after signals are realized, agents choose portfolios to maximize mean-variance utility with an ESG preference term (p. 4, Eq. 3): $$ U_{2j} = \text{E}_{2j}\!\left[W_j\right] - \frac{\rho}{2}\,\text{Var}_{2j}\!\left[W_j\right] + \delta_j G_j \tag{3} $$ where $$\rho > 0$$ is the common risk-aversion coefficient, $$W_j$$ is terminal wealth, and $$G_j = \sum_{i=1}^N q_{ij} g_i$$ is the portfolio ESG score ($$q_{ij}$$ = holding of asset $$i$$, $$g_i$$ = ESG score, mean-zero with $$g_N = 0$$). A higher $$\delta_j$$ implies stronger ESG-driven preferences; $$\delta_j = 0$$ yields standard mean-variance. The key pricing implication follows from Proposition 4 (p. 5). The expected net payoffs are (Eqs. 9-10): $$ \text{E}\!\left[f_N - p_N\right] = \rho\bar{\sigma}_N \tag{9} $$ $$ \text{E}\!\left[f_i - p_i\right] = b_i\,\text{E}\!\left[f_N - p_N\right] + \rho\bar{\sigma}_i - \bar{\delta}_i g_i \tag{10} $$ where $$\bar{\sigma}_i$$ is the cross-agent average posterior payoff variance (the inverse of $$\bar{\sigma}_i^{-1} = \sigma_i^{-1} + \bar{S}_i + \sigma_{p_i}^{-1}$$) and $$\bar{\delta}_i = \bar{\sigma}_i \int \hat{\sigma}_{ij}^{-1}\,\delta_{ij}\,dj$$ is the aggregate, posterior-precision-weighted ESG preference for asset $$i$$ (where $$\hat{\sigma}_{ij}^{-1} = \sigma_i^{-1} + S_{ij} + \sigma_{p_i}^{-1}$$ is agent $$j$$'s posterior precision for asset $$i$$; Proposition 1, p. 4). Equation (10) shows that the expected return on asset $$i$$ is reduced by $$\bar{\delta}_i g_i$$, all else equal: green assets ($$g_i > 0$$) have lower expected returns, and brown assets ($$g_i < 0$$) have higher expected returns. The negative ESG-ICC relation is therefore a direct equilibrium prediction, amplified by the information channel through $$\bar{\sigma}_i$$ (which falls when signals are more precise). **Concavity.** For green assets the ESG preference motive (nonpecuniary benefit $$\delta_j g_i > 0$$) and the information-acquisition motive (more precise signals reduce posterior variance) both push expected returns down. For brown assets the two forces partially offset: the nonpecuniary motive lowers expected returns, but better signals increase them. Hence the negative ESG-return relation is more pronounced for green assets, making the curve concave. ## Method In period 1, each agent chooses signal precision $$S_{ij}$$ for each asset to maximize expected utility (p. 4, Eq. 5). Proposition 2 characterizes the optimum (p. 5, Eq. 6): $$ \hat{S}_{ij} = \max\!\left[0,\; s \;\middle|\; c'_{ij}(s) = \psi_{ij}\right] \tag{6} $$ The pre-cost marginal benefit of information for asset-agent pair $$(i,j)$$ is (p. 5, Eq. 7): $$ \psi_{ij} = \frac{1}{2\rho}\!\left(\bar{\sigma}_i + \left(\rho^2\sigma_X + \bar{S}_i\right)\bar{\sigma}_i^2 + \left(\rho\bar{\sigma}_i + \left(\bar{\delta}_j - \bar{\delta}_i\right)g_i\right)^{\!2}\right) \tag{7} $$ where $$\bar{S}_i = \int S_{ij}\,dj$$ is the cross-agent average signal precision and $$\sigma_X$$ is the variance of the aggregate risk factor supply. The term $$(\bar{\delta}_j - \bar{\delta}_i)g_i$$ captures the ESG motive: funds whose ESG preference $$\bar{\delta}_j$$ is above (below) the aggregate $$\bar{\delta}_i$$ have a higher (lower) marginal benefit of acquiring information about asset $$i$$ when that asset's ESG score $$g_i$$ is nonzero. Proposition 3 establishes that the cross-agent average signal precision increases with the absolute departure from green neutrality (p. 5, Eq. 8): $$ \frac{\partial \bar{S}_i}{\partial |g_i|} = \xi_{Ai}\,\sigma_\delta\,|g_i| > 0 \tag{8} $$ where $$\sigma_\delta$$ is the cross-agent dispersion in ESG preferences and $$\xi_{Ai} > 0$$ is a positive scalar. This proves that aggregated information acquisition rises for both green and brown assets as their ESG scores depart from zero, because the marginal benefit of information acquisition is quadratic in ESG preferences. As a consequence, the informational efficiency of asset prices (price informativeness) increases for stocks with more extreme ESG profiles and for stocks held by funds with more dispersed ESG preferences. The equilibrium is solved by a fixed-point problem on $$\bar{S}_i$$: agents choose optimal signal precisions given aggregate precision, and aggregate precision is consistent with individual choices. The model builds on the information acquisition framework of Breugem and Buss (2019) for institutional investors, extending it to incorporate heterogeneous ESG preferences. The fund performance measure follows Kacperczyk, Van Nieuwerburgh & Veldkamp (2016): the expected excess net payoff (EENP) decomposes into an ESG-based portfolio tilt component and a skill (private signal precision) component, with both building on the `noisy-rational-expectations` and `fama-macbeth` primitives listed above. ## Empirical specifications **Price informativeness (Eq. 14, Table 2, p. 9).** Price informativeness is measured following Bai et al. (2016) as the ability of the current market-to-book ratio to predict future earnings-to-assets. The monthly Fama and MacBeth (1973) regression tests the model predictions about ESGDev and ESGDisp: $$ \frac{E_{i,y+h}}{A_{i,y}} = \alpha + \beta_1\log\!\frac{M_{i,y}}{A_{i,y}} + \beta_2\log\!\frac{M_{i,y}}{A_{i,y}} \times \text{ESGDev}_{i,y} + \beta_3\log\!\frac{M_{i,y}}{A_{i,y}} \times \text{ESGDisp}_{i,y} + \beta_4\,\text{ESGDev}_{i,y} + \beta_5\,\text{ESGDisp}_{i,y} + \beta_6\frac{E_{i,y}}{A_{i,y}} + c N_{i,y} + \varepsilon_{i,y+h} \tag{14} $$ where $$E_{i,y+h}/A_{i,y}$$ is earnings-before-interest-and-taxes over total assets for stock $$i$$ in year $$y+h$$, $$M_{i,y}/A_{i,y}$$ is the market-to-book ratio, $$\text{ESGDev}_{i,y}$$ is the absolute departure from green neutrality (from LASSO residual of MSCI ESG on 94 non-ESG characteristics), $$\text{ESGDisp}_{i,y}$$ is the stock-level dispersion in fund ESG preferences, and $$N_{i,y}$$ stacks all other stock-level controls. Standard errors follow Newey and West (1987). Forecasting horizons are $$h=1$$ year (Models 1-5) and $$h=5$$ years (Models 6-10). **ESG-ICC regression (Eq. 15, Table 4, p. 14).** The implied cost of capital is estimated following Hou et al. (2012) and Pastor, Stambaugh & Taylor (2022). The main Fama and MacBeth (1973) regression is: $$ \text{ICC}_{i,t} = \alpha + \beta_1\,\text{ESG}_{i,t-1} + \beta_2\,\text{IO}_{i,t-1} + \beta_3\,\text{ESG}_{i,t-1} \times \text{IO}_{i,t-1} + c N_{i,t-1} + \varepsilon_{i,t} \tag{15} $$ where $$\text{ICC}_{i,t}$$ is the monthly implied cost of capital for stock $$i$$, $$\text{ESG}_{i,t-1}$$ is a high/low ESG indicator (top/bottom quintile), $$\text{IO}_{i,t-1}$$ is a vector of fund-ownership indicators (Green IO, Brown IO, high/low variants), and $$N_{i,t-1}$$ stacks stock-level controls (Log(Size), Log(BM), ROE, I/A, 1M Return, 12M Return). Standard errors follow Newey and West (1987). **Portfolio double sorts (Table 3).** At the end of each month $$t$$, stocks are first sorted into terciles by Green IO (or Brown IO) and then within each tercile into quintiles by ESG rating, yielding 15 ($$3 \times 5$$) portfolios. Value-weighted ICC is computed in month $$t+1$$ and rebalanced monthly. The HML-R spread (high ESG minus low ESG within each ownership tercile) measures the ESG-ICC relation. The HML-G spread (high minus low ownership within each ESG quintile) measures the effect of fund ESG preference alignment. ICCs are additionally adjusted for the CAPM market factor, the Fama-French six-factor model (FF6), and the characteristic-adjusted DGTW model. ## Datasets used | Dataset | Role in paper | Wiki page | |---|---|---| | CRSP common stocks (daily/monthly returns, prices, shares) | Stock-level returns, market cap, turnover, idiosyncratic volatility, short-term reversal | [WRDS](/wiki/commercial/wrds/) (licensed) | | Compustat annual fundamentals | Book-to-market, profitability, investment, leverage, sales, tangibility, earnings | [WRDS](/wiki/commercial/wrds/) (licensed) | | MSCI ESG Ratings (INDUSTRY_ADJUSTED_SCORE) | Monthly ESG scores, residualized against 94 non-ESG characteristics via LASSO to produce Stock ESG and Stock ESGDev | [KLD / MSCI ESG](/wiki/commercial/kld/) (licensed) | | CRSP mutual fund database (via WRDS MFLINKS) | Monthly net-of-fee fund returns, TNAs, turnover, expense ratio, fund flows, multiple share classes consolidated | [CRSP Mutual Funds](/wiki/commercial/crsp-mutual-funds/) (licensed) | | Thomson-Reuters 13F institutional holdings | Quarterly fund equity holdings, used to compute fund-level ESG preference and stock-level fund ownership (Green IO, Brown IO, ESGDisp) | [Thomson 13F](/wiki/commercial/thomson-13f/) (licensed) | | I/B/E/S analyst forecasts | Analyst coverage and forecast dispersion as stock-level controls; earnings forecasts for ICC computation via Hou et al.
