There has been a recent surge of interest in open source software development, which involves developers at many different locations and organizations sharing code to develop and refine programs. To an economist, the behavior of individual programmers and commercial companies engaged in open...

A significant amount of software development is being outsourced to countries such as India. Many Indian software firms have applied for and received quality certifications like the ISO9001, and the number of quality certified software firms has steadily increased. Despite its growing popularity...

We show how to use field-programmable gate arrays (FPGAs) and their associated high-level synthesis (HLS) compilers to solve heterogeneous agent models with incomplete markets and aggregate uncertainty (Krusell and Smith, 1998). We document that the acceleration delivered by one single FPGA is...

The returns to face-to-face interactions are of central importance to understanding the determinants of agglomeration. However, the existing literature studying patterns of geographic proximity in patent citations or industrial co-location has struggled to disentangle the benefits of...

Open source is key to innovation, but we know little about how to incentivize it. In this paper, we examine the impact of a program providing monetary incentives to motivate innovators to contribute to open source. The Sponsors program was introduced by GitHub in May 2019 and enabled...

"We identify a new set of stylized facts on the 2008-2009 trade collapse that we hope can be used to shed light on the importance of demand and supply-side factors in explaining the fall in trade. In particular, we decompose the fall in international trade into product entry and exit, price...

This paper investigates the impact on bank stock prices of emerging market currency crises and bailouts. The stock market distinguishes between banks with exposure to a crisis country and other banks. In general, banks with exposures to a crisis country are affected adversely by currency events...

Most aggregate theories of financial frictions model credit available at a single cost of financing but rationed. However, using a comprehensive firm-level credit registry, we document both high levels and high dispersion in credit spreads to Brazilian firms. We develop a quantitative dynamic...

Judicial decisions in bankruptcy are often influenced by the goal to preserve employment in financially distressed firms. What are the effects of these pro-labor decisions on workers' earnings and employment trajectories? We construct a new court-level measure of pro-labor bias based on the text...

In this paper, we develop a dynamic model of politicians who can engage in corruption. The model offers important insights into what determines corruption and how to design policy to combat it. We estimate the model using data from Brazil to measure voters' willingness to pay for various...
