Technological innovation in mortgage underwriting and the growth in credit, 1985–2015
The application of information technology to finance, or ?fintech,? is expected to revolutionize many aspects of borrowing and lending in the future, but technology has been reshaping consumer and mortgage lending for many years. During the 1990s, computerization allowed mortgage lenders to reduce loan-processing times and largely replace human-based assessments of credit risk with default predictions generated by sophisticated empirical models. Debt-to-income ratios at origination add little to the predictive power of these models, so the new automated underwriting systems allowed higher ...

Technological Change and Financial Innovation in Banking: Some Implications for Fintech
Financial intermediation has changed dramatically over the past 30 years, due in large part to technological change. The paper first describes the role of the financial system in a modern economy and how technological change and financial innovation can affect social welfare. We then survey the empirical literatures relating to several specific financial innovations, broadly categorized as new production processes, new products or services, or new organizational forms. In each case, we also include examples of significant fintech innovations that are transforming various aspects of banking. ...

Indivisibilities in Distribution
This paper develops and estimates a model of indivisibilities in shipping and economies of scale in consolidation. It uses highly detailed data on imports where it is possible to observe the contents of individual containers. In the model, ?rms are able to adapt to indivisibility constraints by using consolidation strategies and by making adjustments to shipment size. The ?rm determines the optimal number of domestic ports to use, taking into account that adding more ports lowers inland freight cost, at the expense of a higher indivisibility cost. The estimated model is able to roughly ...

Artificial Intelligence Innovation by Financial Innovators: Evidence from US Patents
This paper examines the evolution of artificial intelligence (AI) patent rates (i.e., the number of AI patents/number of firms of the same type) and concentration metrics (i.e., the Herfindahl-Hirschman Index (HHI) and Gini coefficient) among financial market participants from 2000 to 2020. It documents the historical trajectories of AI innovation for regulated banking entities and less-regulated firms, revealing that nonfinancial companies exhibit the highest baseline AI patent rate, while banks show the highest growth in AI patent rate over time. Banks have the highest HHI, and nonfinancial ...
Analyzing the Impact of Programming Skills on Career Outcomes of Software Engineers
The most asked question in any computer science forum is “Which programming language is the best?.” Searching this question on Google yields more than 8 billion results. Reddit alone shows over 19 million results. Another way to ask this question is: Which programming language leads to better career outcomes?

Revisiting Capital-Skill Complementarity, Inequality, and Labor Share
This paper revisits capital-skill complementarity and inequality, as in Krusell, Ohanian, Rios-Rull and Violante (KORV, 2000). Using their methodology, we study how well the KORV model accounts for more recent data, including the large changes in the labor's share of income that were not present in KORV. We study both labor share of gross income (as in KORV), and income net of depreciation. We also use nonfarm business sector output as an alternative measure of production to real GDP. We find strong evidence for continued capital-skill complementarity in the most recent data, and we also find ...

The Evolution of Comparative Advantage: Measurement and Implications
We estimate productivities at the sector level for 72 countries and 5 decades, and examine how they evolve over time in both developed and developing countries. In both country groups, comparative advantage has become weaker: productivity grew systematically faster in sectors that were initially at greater comparative disadvantage. These changes have had a significant impact on trade volumes and patterns, and a non-negligible welfare impact. In the counterfactual scenario in which each country's comparative advantage remained the same as in the 1960s, and technology in all sectors grew at the ...

Skilled Tradable Services: The Transformation of U.S. High-Skill Labor Markets
We study a group of service industries that are skill-intensive, widely traded, and have recently seen explosive wage growth. Between 1980 and 2015, these ?Skilled Tradable Services? accounted for a sharply increasing share of employment among the highest earning Americans. Unlike any other sector, their wage growth was strongly biased toward the densest local labor markets and the highest paying firms. These services alone explain 30% of the increase in inequality between the 50th and 90th percentiles of the wage distribution. We offer an explanation for these patterns that highlights the ...
