We study aggregate capital dynamics in an investment model with idiosyncratic productivity shocks, fixed capital adjustment costs, and irreversibility driven by a wedge between capital purchase and resale prices. We derive sufficient statistics capturing the role of investment frictions on...

In characterizing entrepreneurial behavior, researchers often regard nascent entrepreneurs entering risky markets as overconfident. In this paper, we challenge this prevailing view and show that a more differentiated consideration reveals the effects of overconfidence on market entry to be...

Social media is becoming one of the main sources of unstructured data. Many financial analysts use Twitter to gather data and obtain meaningful insights. Recently, high-profile politicians like President Trump have been using Twitter to communicate with the public. The President's Tweets are...

Management Information Systems are meant to create methods for data management, leading to better decision making. By designing, implementing and using business information systems in innovative ways, the effectiveness and efficiency of every-day activities significantly increases. In the...

We use monthly data covering a century-long sample period (1915–2021) to study whether geopolitical risk helps to forecast subsequent gold volatility. We account not only for geopolitical threats and acts, but also for 39 country-specific sources of geopolitical risk. The response of...

In this paper, we investigate the presence of non-linearities in the transmission of geopolitical risk (GPR) shocks. Our methodology involves incorporating a non-linear function of the identified shock into a VARX model and examining its impulse response functions and historical decomposition....

This paper investigates the impact of price transparency on equilibrium prices and fees by considering a policy change implemented by Airbnb that affected the transparency of cleaning fees for IP addresses from the European Union (EU). Using a difference-in-differences approach, we find a...

We report a surprising property of u-o-preferences: the assumption of nonincreasing relative risk aversion implies the optimal portfolio being riskless. We discuss a solution of that paradox in detail. (JEL D80, G11, D10).

The conflicting views that agents and voters have about redistributive taxation have been broadly studied. The literature has focused on situations where the counterfac- tual outcomes that would have occurred had other actions been chosen are observable or point identified. I analyze this...

How does the quality of information received by voters affect political polarisation? We address this long-standing question using an election competition model in which voters have to infer an unknown state from some noisy and biased signals. Their policy preferences are shaped by the posterior...
