Knowledge that Transforms

Abstract We study privatization and corporate ownership in transportation infrastructure, focusing on global airports. Privatization in general does not improve performance. However, private equity (PE) ownership has strong and persistent positive effects on efficiency, volume, and quality, with positive externalities for the local economy. We address selection using close auctions where PE and non-PE firms bid. PE funds expand physical capacity and encourage larger planes while adding low-cost carriers and international routes. They are especially effective in countries with more corruption or state-owned flag carriers. In contrast, the poorer performance of non-PE acquirers may reflect private benefits and historical state ties.

Abstract I document a significant gender gap in entrepreneurs’ access to early-stage equity financing. Using unique administrative data on French startups, I show that this gap is particularly pronounced in male-dominated sectors. Controlling for a comprehensive set of entrepreneur and startup characteristics—including demographics, backgrounds, and motivations—accounts for 42% of the average gender gap. However, in male-dominated sectors, 80% of the gap remains unexplained. Growth-oriented female entrepreneurs rely more heavily on bank loans, substituting equity with debt. Finally, VC-backed female-founded startups outperform their male counterparts in male-dominated sectors. These findings suggest that context-dependent stereotypes influence equity financing decisions.

Abstract We survey retail investors at an online bank to study how beliefs about the autocorrelation of aggregate stock returns shape investment decisions measured in administrative account data. Individuals’ beliefs exhibit substantial heterogeneity and predict trading responses to market movements. We inform half of our respondents that, historically, the autocorrelation was close to zero, which causes them to update their perceived current autocorrelation and return expectations. The treatment shifts respondents’ equity purchases during the COVID-19 crash months later in the direction implied by the intervention. Our results provide causal evidence about the drivers of disagreement and trade in asset markets.

Abstract We show that banks cross-sell future deposits and loans to existing household depositors. A bank is 20-percentage-points more likely to sell a loan to an existing depositor than to an otherwise comparable household. Existing depositors pay a premium when borrowing, and we find no indication that banks obtain an informational advantage on such borrowers, suggesting that the cross-selling is driven more by demand than by supply complementarities. These demand complementarities are in turn driven more by stickiness rather than by unobserved persistent preferences. Finally, banks internalize future cross-selling potential when setting deposit rates.

Abstract A key question for studying business dynamism is whether the costs of regulatory compliance fall homogeneously on small and large businesses. Using comprehensive establishment-level occupational microdata and occupation task information, we quantify a firm’s compliance costs as the share of wage bill for performing regulatory compliance tasks (RegIndex). We reveal an inverted-U relationship between firms’ RegIndex and their size: On average, RegIndex for mid-sized firms with around 500 employees is about 47% greater than that of the smallest firms and 18% greater than that of the largest firms. We further develop a shift-share methodology to disentangle the influence of regulatory requirements and enforcement on driving firms’ compliance costs.

Abstract We study the interaction between firms, which can invest in green technologies, and a government, which can impose emission caps but has limited commitment power. Investment in green technologies generates innovation spillovers, reducing the cost of further investments. Spillovers generate intertemporal strategic complementarities between firms and government, and equilibrium multiplicity. In a “green equilibrium”, firms, anticipating caps, invest in green technologies, which reduces the cost of further investment, making the government willing to cap emissions. In a “brown equilibrium”, firms, anticipating no caps, don’t invest, so green technologies remain costly and the government gives up on emission caps.

Abstract We estimate price elasticities of housing supply for U.S. cities by examining the impact of foreign purchases on housing prices and quantities. After other countries introduced foreign-buyer taxes beginning in 2011, both house prices and quantities increased more in locations with high foreign-born populations. An increase in global capital inflows, instrumented with tax policy changes scaled by immigrant exposure, increased prices and quantities over 2011–2018. We combine these estimates to construct new local supply elasticities, which average 0.26 and range from 0.06 to 0.9. Compared to prior estimates, our elasticities are more inelastic and change cities’ relative rankings.

Abstract We estimate β-δ time preferences and relative risk aversion (RRA) using a lifecycle model including stochastic income, liquid and illiquid assets, credit cards, dependents, Social Security, mortality, and bequests. Preference parameters are identified by cross-tabulating four lifecycle age intervals and four balance sheet moments: the share of households carrying (ie, revolving) credit card debt, average carried credit card debt, average net wealth among households carrying credit card debt, and average net wealth among households not carrying credit card debt. The 16 moments are approximately matched by (MSM) parameter estimates β=0.53, δ=0.99, and RRA = 1.9.

Abstract During the COVID-19 pandemic (2020-2022), Chinese cities witnessed a paradox: residential land and new house prices surged while transaction volumes plummeted. We attribute this to local governments’ active price management through supply controls, land acquisitions by local government financing vehicles (LGFVs), and limits on new home sales permits. Cities more dependent on land sales and land-backed debt before the pandemic experienced greater price increases and price–volume divergence, with LGFVs buying more land at higher prices than other buyers. These interventions helped sustain fiscal financing but deepened developers’ financial distress, revealing unintended consequences of local governments’ fiscal strategies during downturns.

Abstract Environmental, social, and governance (ESG) funds have heterogeneous incentives to engage with portfolio firms. If funds view ESG as a value driver, then these incentives will affect funds’ behavior and thus their impact on firms. We compare ESG funds with similar levels of ESG investments but different incentives to engage. Funds with higher incentives to engage, that is, committed ESG funds, conduct more ESG-related information acquisition, pursue longer term investment strategies, engage more intensely on ESG issues, and have greater real impacts. Moreover, committed ESG funds have outperformed other ESG funds within subportfolios with higher and more effective ESG engagement.
