LMQ-Sketch: Lagom Multi-Query Sketch for High-Rate Online Analytics
Data sketches balance resource efficiency with controllable approximations for extracting features in high-volume, high-rate data. Two important points of interest are highlighted separately in recent works; namely, to (1) answer multiple types of queries from one pass, and (2) query concurrently with updates. Several fundamental challenges arise when integrating these directions, which we tackle in this work. We investigate the trade-offs to be balanced and synthesize key ideas into LMQ-Sketch…

The Republican Majority on the Senate Banking Committee released a press release Friday confirming that they were intentionally eliminating
the “duplicative Office of Financial Research (OFR)”.
According to sources I’ve talked to in the Senate, Republican committee members have shown little concern with the elimination of the Office of Financial Research.
They also seem aware of the concerns over SOFR, because both their “one pager” and “section by section” documents clai…

The “One Big Beautiful Bill Act” Eliminates the Office of Financial Research—Threatening the Stability of the Treasury Market
Early last week I started working on a piece on why the Federal Reserve didn’t step in during the Trump Tariff Financial Panic. The basic idea of that piece is simply that “repo rates”- the interest rate at which you can, in essence, borrow funds with treasury securities

Measuring Communication Quality of Interest Rate Announcements
We use text-mining techniques to measure the accessibility and quality of information within the texts of interest rate announcements published by the Bank of Israel over the past decade. We find that comprehension of interest rate announcements published by the Bank of Israel requires fewer years of education than interest rate announcements published by the Federal Reserve and the European Central Bank. In addition, we show that the sentiment within these announcements is aligned with economi…

Top U.S. Multifamily Rent Growth Markets — Q1 2025
"As was the case during 2024, the top rent growth markets to start 2025 represented several regions, all with varying strengths and characteristics."

Top U.S. Multifamily Rent Growth Markets Q1 2025 - Arbor Realty
The U.S. multifamily sector finished 2024 with the wind at its sails, as the market settled into a more normalized cycle with emerging opportunities. The sector’s resilience stood out during the year, amid a shifting economic landscape and volatile interest rate environment.

A Sinusoidal Hull-White Model for Interest Rate Dynamics: Capturing Long-Term Periodicity in U.S. Treasury Yields
This study is motivated by empirical observations of periodic fluctuations in interest rates, notably long-term economic cycles spanning decades, which the conventional Hull-White short-rate model fails to adequately capture. To address this limitation, we propose an extension that incorporates a sinusoidal, time-varying mean reversion speed, allowing the model to reflect cyclic interest rate dynamics more effectively. The model is calibrated using a comprehensive dataset of daily U.S. Treasu…

Export proceeds repatriation policies: A shield against exchange rate volatility in emerging markets?
We examine the impact of mandatory export proceeds repatriation on exchange rate stability in three emerging markets, Iran, Sri Lanka, and Turkey, using the Generalized Synthetic Control framework. By modeling exchange rate stochastic volatility as our outcome of interest and controlling for interest rate differentials, exchange rate regime shifts, and inflation rate gaps, we address both unobserved time-varying confounders and heterogeneous treatment effects. Our estimates reveal no statistica…

The dollar sank to its lowest level in more than three years on Thursday
and the FTSE 100 closed at a record high as Donald Trump’s latest trade threats and the weakening economy appeared to bring forward interest rate cuts by the Federal Reserve.
Foreign exchange traders sold the dollar in favour of the yen and the euro,
which both climbed by about 1% against the US currency to leave it almost 10% down on its value against a basket of currencies since the beginning of the …

Hedging Deposit Run Risk Prior to the 2023 Regional Banking Crisis
In this analysis we determine factors driving the cross-sectional variation in uninsured deposits during the interest rate raising cycle of 2022 to 2023. The goal of our analysis is to determine whether banks proactively managed deposit run risk prior to the hiking cycle which produced the 2023 Regional Banking Crisis. We find evidence that interest rate forward, futures, and swap use affected the change in a bank uninsured deposits over the period. Interest rate option use, however, has no eff…

Inference on panel data models with a generalized factor structure
We consider identification, inference and validation of linear panel data models when both factors and factor loadings are accounted for by a nonparametric function. This general specification encompasses rather popular models such as the two-way fixed effects and the interactive fixed effects ones. By applying a conditional mean independence assumption between unobserved heterogeneity and the covariates, we obtain consistent estimators of the parameters of interest at the optimal rate of conve…

Expansion-history preferences of DESI DR2 and external data
We explore the origin of the preference of DESI DR2 baryon acoustic oscillation (BAO) measurements and external data from cosmic microwave background (CMB) and type Ia supernovae (SNIa) that dark energy behavior departs from that expected in the standard cosmological model with vacuum energy ($Λ$CDM). In our analysis, we allow a flexible scaling of the expansion rate with redshift that nevertheless allows reasonably tight constraints on the quantities of interest, and adopt and validate a simp…

Branch lengths for geodesics in the directed landscape and mutation patterns in growing spatially structured populations
Consider a population that is expanding in two-dimensional space. Suppose we collect data from a sample of individuals taken at random either from the entire population, or from near the outer boundary of the population. A quantity of interest in population genetics is the site frequency spectrum, which is the number of mutations that appear on $k$ of the $n$ sampled individuals, for $k = 1, \dots, n-1$. As long as the mutation rate is constant, this number will be roughly proportional to the t…

Split the Yield, Share the Risk: Pricing, Hedging and Fixed rates in DeFi
We present the first formal treatment of \emph{yield tokenization}, a mechanism that decomposes yield-bearing assets into principal and yield components to facilitate risk transfer and price discovery in decentralized finance (DeFi). We propose a model that characterizes yield token dynamics using stochastic differential equations. We derive a no-arbitrage pricing framework for yield tokens, enabling their use in hedging future yield volatility and managing interest rate risk in decentralized l…
