This entry pertains to the Junior Finance Conference held at The University of Wisconsin-Madison School of Business. I summarize my reactions to each of the papers followed by some outstanding questions at the end.

Introduction

This was my first time in Madison, Wisconsin. It was particularly memorable as I had the chance to reconnect with Sebastien Plante, now an assistant professor there. Having worked as his undergraduate RA, it was rewarding to catch up with him at his home base.

The conference also provided an opportunity to meet other junior researchers who were on the job market with me and reflect on our shared experiences. Many UW Madison faculty also came to the seminar, and I enjoyed my conversations with them given their strong interest in macro finance and asset pricing topics.

Papers

• Julia Fonseca presented a new paper that explores the possibility that mortgage lock-in is the reason for the recent rise in house prices. The basic idea is that homeowners with low locked-in mortgage rates are reluctant to sell their homes and take on new mortgages at higher current rates, reducing housing supply and potentially driving up prices. There are many things outside the model (e.g. role of monetary policy, production of housing) but they are also not necessarily critical, as their goal is to isolate and quantify the specific effects of mortgage lock-in on housing market dynamics. This was also my first time learning about a “housing ladder” model, which is basically a framework that captures how households move between different types of housing (e.g., from renting to owning starter homes to owning larger homes) over their lifecycle. This setup can be then used to study how factors like lock-in affect mobility and prices across different segments of the housing market.
• Naz Koont presented her job market paper that explores how the availability of digital banking platforms impacts bank competition. The basic idea is that digital platforms allow banks to compete in new geographic markets without opening physical branches, potentially altering the competitive landscape. The paper also tackles a thorny identification challenge using a clever instrumental variables analysis based on cellular coverage patterns, which I thought was quite nice.
• Jacob Conway presented his job market paper on how consumers respond to firm social stances. I thought he described his overall approach quite nicely using a simple equation that everyone could understand: where each term is an “estimation target” for his empirical work. A key step in his approach is to impute the ideological dimension of each consumer based on observables and use this classification for analysis. I found this method intriguing, but it also raised questions in my mind about how one should treat the potential errors-in-variables issue that could arise from this imputation process. This methodological concern could have implications for the interpretation and robustness of the results.
• Lira Mota presented a new paper studying why some firms opt to have a complex debt structure. Their story is that firms strategically issue different types of bonds to cater to heterogeneous investor demands, thereby minimizing their cost of capital and diversifying their funding risk. This financially sophisticated behavior allows firms to increase their resilience to credit market shocks and potentially enhance firm value. Two main questions that I had (which also came up in the audience) are:
  • How do we distinguish the underwriter’s incentives from the firms’ incentives in issuing multiple bonds? It’s unclear whether the observed complex debt structures are primarily driven by firms’ strategic decisions or by underwriters pushing for more issuances to generate fees.
  • Why aren’t all firms engaging in this practice given the apparent benefits? If issuing multiple bond types truly provides such advantages in terms of cost reduction and risk diversification, it’s puzzling that we don’t see this behavior universally adopted across all firms.
• Markus Bak-Hansen presented his job market paper examining dealer-customer relationships in over-the-counter (OTC) markets. Using data from a large European dealer, the paper finds that customers with strong relationships receive significantly lower bid-ask spreads and more frequent quotes. What I found particularly interesting is the role of salespeople in coordinating within the dealer organization to ensure relationship discounts are applied across asset classes.

Takeaways

1. It’s actually mind-blowing how many cool research projects are out there. This conference was a good reminder that it’s important to keep up with different areas of finance, and that having broad knowledge helps you appreciate all these different talks and maybe even spark some wild ideas of your own. Plus I think it can be also fun to see how all these seemingly unrelated topics somehow connect in the grand scheme of things.
2. The energy from the researchers is quite infectious. Going to these conferences serves as a good reminder of why we got into this field in the first place.
3. You’d think presenting your job market paper would be easy since you know it so well, but even for this one I had to spend a lot of time in preparation. It’s a good reminder that knowing your stuff is only part of it — being able to explain it clearly and handle tricky questions is a whole other skill. But I think when you put in that work, it really shows.
