We study the effects of technological change on financial intermediation, distinguishing between innovations in information (data collection and processing) and communication (relationships and distribution). Both follow historical trends towards an increased use of hard information and less in-person interaction, which are accelerating rapidly. We evaluate more recent innovations, such as the combination of data abundance and artificial intelligence, and the rise of digital platforms. We argue that the rise of new communication channels can lead to the vertical and horizontal disintegration of the traditional bank business model. Specialized providers of financial services can chip away activities that do not rely on access to balance sheets, while platforms can interject themselves between banks and customers. We discuss limitations to these challenges to the traditional bank business model, and the resulting policy implications.

We identify the unique role of the government bond lending market in collateral transformation during periods of market stress. Using a novel database, we provide evidence that safe assets in the lending market have higher demand, higher borrowing cost, and higher usage of noncash collateral relative to nonsafe assets during stressed market conditions. Moreover, we find that market participants are able to obtain safe assets using relatively low-quality noncash collateral, allowing for collateral transformation. We show that policy interventions by central banks can help reduce safe-asset shortages by returning sought-after safe assets to the market.

Using a comprehensive database of European firms, we study the effect of market entry regulations on the creation of new limited-liability firms, the average size of entrants, and the growth of incumbent firms. We find that costly regulations hamper the creation of new firms, especially in industries that should naturally have high entry. These regulations also force new entrants to be larger and cause incumbent firms in naturally high-entry industries to grow more slowly. Our results hold even when we correct for the availability of financing, the degree of protection of intellectual property, and labor regulations.

We provide estimates of profit shifting for over 2 million firm-year observations in 100 countries over the period 2009–2020. Employing nonparametric estimation techniques within a mainstay model of profit shifting, we examine how the profits of both parent and subsidiary firms within a multinational group respond to marginal changes in the composite tax indicator. The key advantage of this approach is that it yields firm-year estimates of profit shifting. Multinational firms engage in extensive profit shifting by maintaining affiliates in low-tax countries and zero-tax havens. Multinational groups with an ultimate tax-haven owner exhibit the largest profit response to tax incentives. Our new database opens important avenues for analyzing the sources and effects of profit shifting.

We employ a novel dataset on almost 30,000 trade credit contracts to describe the broad characteristics of the parties that contract together and the key contractual terms of these contracts. Whereas prior work has typically used information on only one side of the buyer-seller transaction, this paper utilizes information on both, allowing for the first analysis of buyer-seller pairs. An equally important distinction is that we have multiple contracts for the same buyer or supplier firms, rather than a firm-average response, allowing for the correction of time-invariant firm characteristics that might determine the choice of credit terms. We find that the largest and most creditworthy buyers receive contracts with the longest maturities from smaller suppliers, and that discounts for early payment tend to be offered to riskier buyers.

We show that lender of last resort (LOLR) policy exacerbates bank interconnectedness. Using novel micro-level data, we analyze LOLR’s haircut gaps: the differences between the private market and central bank haircuts. LOLR policy incentivizes banks to increase pledging and holdings of higher haircut-gap bonds, especially those issued by domestic and systemically important banks. Effects only apply to banks, not to nonbanks without LOLR access. LOLR funding revives bank bond issuance associated with higher haircut gaps and increases the subsequent correlation between pledging and issuing banks’ bond prices, in particular during periods of low-market returns and for domestic, systemically important banks.

This paper is the first to show that financial institutions may be effectively undercapitalized as a result of incomplete consolidation of minority ownership. Using two approaches – consolidating the minority-owned affiliates with the parent or deducting equity investments in minority ownership from the parent's capital – we find that the effective capitalization ratios of small US bank holding companies (BHCs) are substantially lower than the reported ratios. Empirical evidence suggests that the effectively lower capitalization ratios are associated with higher riskiness at the BHC level. Capital adjustments following pro forma consolidation better capture the additional risks than capital adjustments in the form of equity deductions for investments in minority-owned affiliates. These findings have important implications for the regulation of bank capital.

We examine gender differences in career progression and promotions using personnel data from the European Central Bank (ECB) during the period 2003–2017. A gender wage gap emerges within a few years of hiring, despite broadly similar entry conditions. We also find a gender promotion gap before 2010 when the ECB issued a public commitment to diversity. Following this change, the promotion gap disappears. Using data on promotion applications, we find a gender application bias, partly driven by preferences for competition. Following promotion, women perform better in terms of salary progression.

We show that in a canonical model with heterogeneous entrepreneurs, financial frictions, and an imperfectly elastic supply of capital, a fall in the interest rate has an ambiguous effect on aggregate economic activity. In partial equilibrium, a lower interest rate raises aggregate investment both by relaxing financial constraints and by prompting relatively less productive entrepreneurs to invest. In general equilibrium, however, this higher demand for capital raises its price and crowds out investment by more productive entrepreneurs. When this reallocation is strong enough, a fall in the interest rate reduces aggregate output. A numerical exploration of the model suggests that this reallocation effect is quantitatively significant and—in response to persistent changes in the interest rate—stronger than the traditional balance-sheet channel. We provide evidence of the reallocation effect using U.S. firm-level data.

We study the mechanisms driving bank losses across historical banking crises in 46 economies and the effectiveness of policy interventions in restoring bank capitalization. We find that bank stocks experience large, permanent declines at the onset of crises. These losses predict commensurate long-term declines in banks’ earnings and dividends, rather than elevated future equity returns. Bank losses are primarily driven by write-downs of nonperforming assets, not asset sales during panics. Forceful liquidity-based interventions during crises predict only small, temporary increases in bank market value. Overall, these results suggest that bank losses during crises are not primarily due to temporary price dislocations. Early liquidity interventions can avert banking crises, but only under specific conditions. Once large bank equity declines have occurred, policy responses have historically failed to prevent persistent undercapitalization in the banking sector.
