Title: Myopic Price Promotions in IPOs: Evidence from Ride-Hailing Platforms Myopic Price Promotions in IPOs: Evidence from Ride-Hailing Platforms

The year 2019 witnessed two unicorn IPOs from ride-hailing platforms: Lyft at a $24.3 billion valuation and Uber at a $82.4 billion valuation. Did these platforms strategically adjust their marketing decisions before their IPOs to appease investors? To answer this question, we use a comprehensive, granular, panel dataset with 13 million rides completed by 250,000 consumers between January 2018 and July 2019. Using each IPO filing day as a natural experiment, we examine how these two events influenced the price promotional decisions of Lyft and Uber. Using several econometric models, we quantify the IPO impact on platforms' decisions (promotion strategy) and performance metrics (number of rides). We find strong evidence that both platforms substantially adjusted their price promotions before their IPO filings. Lyft and Uber increased their price promotions by 49% and 68% respectively. We find that the impact on performance metrics was different for Lyft and Uber, given Lyft's first mover advantage. In addition, we find that online platforms boosted their pre-IPO performance by personalizing their price promotional decisions based on customer characteristics such as loyalty, price sensitivity, deal seeking behavior, tipping behavior, riding frequency, trip length, and geographical location to appease prospective investors before their IPOs.

Title: On the Rise of Payment Firms
Payment firms have experienced an exceptional growth over the past decade, with payment firms’ market capitalization now exceeding the combined market capitalization of all banks in the U.S. We show that stock returns of payment firms are strongly correlated with stock returns of Ecommerce firms. Using three million observations at an online retailer, we provide micro-level evidence on the importance of payment firms for E-commerce purchases. When a customer’s preferred payment type is not seamlessly available, approximately a quarter of customers abandon the purchase instead of switching to a different payment type. We document this strong clientele effect both for credit cards, PayPal, as well as Buy-Now-Pay-Later (BNPL) products. Our results suggest that – although E-Commerce firms have access to many payment types – each payment firm has a significant bargaining power vis-à-vis E-Commerce firms.

Title: Growing SMEs The sensitivity of investment and employment to the cost of debt financing.
How sensitive is the growth of small firms to the cost of borrowing? This paper uses variation in the access to a credit certification program in Portugal to estimate the sensitivity of small and medium sized firms (SMEs)´ investment and employment to the cost of debt financing. The program was implemented during the global financial crisis to prevent small firms from becoming credit constrained. The targeted program provides a credit certification as well as a loan guarantee by the Portuguese government to firms with a minimum credit quality. The program design and implementation allows for a multidimensional regression discontinuity methodology to estimate its real effects over a decade. When comparing firms around cutoff points, we find that eligible firms increase their borrowing, and borrow at significantly lower rates than non-eligible firms. Targeted firms also increase investment and employment when compared to non-certified firms. The program was effective in ensuring small firms continued to grow during the financial crisis, while the certification effects matter mostly in the postcrisis period.

Title: We investigate the impact of institutions on the transmission of shocks across firms. Using novel inter-firm wire transfer data, we find that suppliers exposed to natural disasters pass this shock to their customers, particularly when the court system is congested. Evidence suggests that congested courts amplify spillovers through contracting frictions of customers with new suppliers and creditors. Subsequently, customers seem to vertically integrate the production of affected inputs and obtain liquidity by selling their accounts receivables. Our results highlight the importance of institutions.

Title: When the remedy is the problem: Risk governance in independent bank boards
We study the independence ratio, as well as the financial expertise of independent directors for 625 U.S. bank holding companies (BHC) from 2000 to 2015, to concentrate on causes of the subprime crisis: short-termism, poor monitoring, and excessive risk-taking. Following Enron and Sabanes-Oxley, independence ratios rised; while official responses to the subprime crisis claim that (even then) bank directors were not independent enough, we find that higher independence ratios decrease the monitoring quality of the board and increase short-term incentives for the CEO. Finally, boards with a higher fraction of independent directors decrease standard measures of bank risk, but promote tail risk taking.

Title: Spatial Mobility and Labor Market Outcomes: Evidence from Credit Lotteries
In this paper, we examine the effect of access to individual mobility on labor market outcomes. We exploit exogenous time-series variation in access to individual mobility through credit lotteries that randomly allocate credit designated for motorcycle purchase to participants of a financial product in Brazil. We find that upon access to a motorcycle, individuals exhibit higher formal employment rates and earnings. Consistent with a geographically broader job search, individuals move to jobs further away from home and harder to reach by public transportation. Investment in individual mobility yields an annual rate of return of 17 percent over an individual's career.

I investigate whether banks adjust balance sheet variables strategically in the wake of anticipated bank employee union strikes using a difference-in-difference design. Using hand-collected strike information and bank-municipality level bank balance sheet data in Brazil, I find a robust causal relationship between union strikes and bank manipulations in accrual account, asset portfolio and liquidity position within a short time period just before the routinely happened strikes from 2006 to 2016. Specifically, I find that banks significantly increased their loan loss provision ratio, decreased security and instrument trading and loans, and held less cash and interbank liquidity in municipalities mobilized to go on strikes just before strikes. These results are most consistent with my bargaining motive hypothesis that banks account fewer current earnings reported and expected future cash flows, and less liquidity revealed to employee unions just before the anticipated strikes in order to strengthen their bargaining power in wage negotiations.
