Knowledge that Transforms

This paper demonstrates practical arbitrage trading on the cryptocurrency market. It provides guidance on how to build a high-frequency trading system that benefits from exhibiting arbitrage opportunities. It reveals the algorithm of the trading bot that incorporates the order placement and execution strategy between decentral and central cryptocurrency exchanges. The arbitrage algorithm is implemented on two different blockchains that interact with Uniswap and Balancer folks. Current research explores arbitrage opportunities with back-testing models, the paper focuses on trades with realized arbitrage trades. Practical arbitrage includes all operational costs, liquidity constraints, direct effects on markets, and competition with peer arbitrage traders.

We investigate the portfolio frontier and risk premia in equilibrium when institutional investors aim to minimize the tracking error variance and to attain a certain ESG score (ESG mandate). Provided that a negative ESG premium is priced by the market, we show that an ESG mandate can reduce the mean–variance inefficiency of the portfolio frontier when the asset manager targets a limited over-performance return with respect to the benchmark. In equilibrium, with mean–variance investors and asset managers endowed with an ESG mandate, a negative ESG premium arises if the mandate is binding for asset managers. The negative ESG premium is due to the ESG constraint (institutional investors over-invest in virtuous ESG stocks). We find empirical evidence of such a negative premium in the US market.

We examine the impact of CEOs’ public charity affiliations on corporate labor violations and find that public-charity-affiliated CEOs have a lower likelihood of engaging in labor violations than their non-affiliated peers. In a disaggregated analysis, we find the result to be driven primarily by wage and hour violations. This finding is validated when we compare changes in wage and hour violations around different types of CEO turnover. We further identify the promotion of a positive corporate culture and an increase in labor-related expenditures as the main channels through which CEOs’ public charity affiliations affect wage and hour violations. In addition, we find that firms led by public-charity-affiliated CEOs experience lower employee turnover. The impact of public-charity-affiliated CEOs on reducing the likelihood of wage and hour violations is persistent and is more pronounced for CEOs who exhibit more altruistic behavior prior to assuming office. Overall, we provide persuasive evidence that CEOs’ public charity affiliations are beneficial to firms.

We investigate how stakeholder-centric corporate misconduct (CM) influences firms’ financial policies. CM is associated with higher cash holdings and lower dividend payouts and debt financing. These effects are more pronounced in firms with stronger governance. We further show that high cash holdings in CM firms are associated with higher firm value and lower implied cost of capital. Firms that replace their CEOs following CM adopt more conservative financial policies. Our evidence supports the precautionary motive for cash holdings, indicating that such reserves are unlikely to result from agency conflicts or increased managerial discretion in CM firms.

This paper studies a novel method to help people make better decisions by providing information immediately after customers make a costly transaction. We examine an intervention by a major financial institution in Australia, where credit card customers in a treatment group received a text message immediately after each high-cost transaction. The notification informed them that the transaction resulted in an additional fee and that a higher interest rate would apply immediately. This immediate ex-post information nudge reduces the number of subsequent high-cost transactions by 6% and increases the likelihood of making a repayment on the day they were nudged by 5%. This evidence is consistent with the ex-post information campaign increasing awareness among customers about the fees and higher interest rate which subsequently caused them to adjust their credit card usage to save money. More generally, this evidence provides a novel method to help people make better decisions by nudging immediately after rather than before an event.
