● Needs Are Not Enough: The Gravity of Private Cross-border Infrastructure Investments, joint with Margaux Deltel and Stefan Morkötter
Abstract: Global infrastructure needs are substantial. Especially in emerging and developing economies where government budgets are smaller and the domestic investor base is limited, private cross-border infrastructure investments are crucial in financing these needs. However, globally, private capital does not flow to where needs are greatest. Therefore, this paper explains global infrastructure investment patterns and asks when infrastructure needs become investable opportunities for private sponsors. In doing so, we develop a two-sided structural gravity framework that explains 49,268 unique private cross-border infrastructure transactions across 169 origin and 214 destination countries from 2005 to 2025. We show that investment follows a pronounced gravity pattern shaped by geographical distance, political alignment, and prior bilateral experience. Most importantly, infrastructure needs attract private capital on average, but primarily in destinations with stronger governance, deeper financial systems, and more stable macroeconomic conditions. Hence, private sponsors finance infrastructure needs only when the destination environment makes them bankable.
● Heterogeneous Housing Valuation
Abstract: The pricing of residential real estate is driven by individual households’ preferences for housing services. In this study, I show how households with different sociodemographic characteristics value specific housing attributes heterogeneously. In doing so, I make use of a special auction design and a novel measure of private preference pressure, which reflects a household’s necessity to reveal its true private value estimate when buying a dwelling. Based on this economic mechanism, I use a threefold decomposition technique to show how a high and low amount of sociodemographic characteristics in a neighborhood, like income, education, age, and family status, lead to varying private value estimates of specific housing attributes. Creating a typical low- and high-characteristic buyer in a neighborhood further proves our main finding. Additionally, I exploit the introduction of stricter lending rules in a triple difference-in-difference setting to show how an asymmetric shock to the budget constraint of one of two buyer groups causally increases heterogeneous housing valuation in light of high preference pressure in an auction.
