wikifolio Financial Technologies


I am the Head of Business Intelligence and Data Science at the social trading platform wikifolio.

Before joining wikifolio, I graduated from the Vienna Graduate School of Finance where my research focused on the economics of technological innovations in the financial sector. One of my papers shows how blockchain-based settlement introduces limits to arbitrage in cross-market trading. In another paper, I analyze how consumers react to the introduction of overdraft facilities through a mobile banking app. In my solo-authored paper, I investigate the potential of crowdfunding mechanisms to elicit demand information and improve the screening of viable projects under different valuation structures.

In my spare time, I replicate asset pricing approaches or build visualizations for arbitrary economic stories which all eventually end up on this page.

Crowdfunding and Demand Uncertainty

Reward-based crowdfunding allows entrepreneurs to sell claims on future products to finance investments and, at the same time, to generate demand information that benefits screening for viable projects. I characterize the profit-maximizing crowdfunding mechanism when the entrepreneur knows neither the number of consumers who positively value the product, nor their reservation prices. The entrepreneur can finance all viable projects by committing to prices that decrease in the number of pledgers, which grants consumers with high reservation prices information rents. However, if these information rents are large, then the entrepreneur prefers fixed high prices that lead to underinvestment.

Building Trust Takes Time: Limits to Arbitrage in Blockchain-Based Markets

Distributed ledger technologies replace trusted clearing counterparties and security depositories with time-consuming consensus protocols to record the transfer of ownership. This settlement latency exposes cross-market arbitrageurs to price risk. We theoretically derive arbitrage bounds that increase with expected latency, latency uncertainty, volatility and risk aversion. Using Bitcoin orderbook and network data, we estimate arbitrage bounds of on average 121 basis points, explaining 91% of the observed cross-market price differences. Consistent with our theory, periods of high latency-implied price risk exhibit large price differences, while asset flows chase arbitrage opportunities. Blockchain-based settlement thus introduces a non-trivial friction that impedes arbitrage activity.

Perceived Precautionary Savings Motives: Evidence from FinTech

In a representative sample of new borrowers, access to lines of credit increases the spending of more liquid households permanently. Liquid consumers reduce their existing savings but do not tap into negative deposits, and hence do not raise debt. Through our FinTech bank setting, we elicit consumers’ risk preferences, beliefs, perceptions, and other characteristics directly. No proxies for precautionary savings motives differ systematically across liquid and illiquid consumers. Liquid consumers appear to have higher subjective beliefs about precautionary savings, despite no different objective characteristics. Our results have implication for the transmission of policy to households through bank credit.

Fishing with Pearls: The Value of Lending Relationships with Prestigious Firms

We provide novel evidence of banks establishing lending relationships with prestigious firms to signal their quality and attract future business. Using survey data on firm-level prestige, we show that lenders compete more intensely for prestigious borrowers and offer lower upfront fees to initiate lending relationships with prestigious firms. We also find that banks expand their lending after winning prestigious clients. Prestigious firms benefit from these relations as they face lower costs of borrowing even though prestige has no predictive power for credit risk. Our results are robust to matched sample analyses and a regression discontinuity design.
