This paper builds a recommendation system for borrowers on P2PL platforms to lower interest rates.
We argue that a negative interest rate policy (NIRP) can be an effect tool for macroeconomic stabilization. We first discuss how implementing negative rates on reserves held at a central bank does not pose any theoretical difficulty, with a reduction in rates operating in exactly the same way when rates are positive or…
This paper investigates the relevance of the No-Ponzi game condition for public debt (i.e. the public debt growth rate has to be lower than the real interest rate, a necessary assumption for Ricardian equivalence) and of the transversality condition for the GDP growth rate (i.e. the GDP growth rate has to be lower than…
New models for short rates show longer periods at higher rates.
The currency carry trade is the investment strategy that involves selling low interest rate currencies in order to purchase higher interest rate currencies, thus profiting from the interest rate differentials. This is a well known financial puzzle to explain, since assuming foreign exchange risk is uninhibited and the …

This is a well known financial puzzle to explain, since assuming foreign exchange risk is uninhibited and the mark…
The paper models stochastic interest rates for life insurance using phase-type distributions.
Italian banks use swaps to hedge against rising interest rates, offsetting losses on debt securities.
In general, homeowners refinance in response to a decrease in interest rates, as their borrowing costs are lowered. However, it is worth investigating the effects of refinancing after taking the underlying costs into consideration. Here we develop a synthetic mortgage calculator that sufficiently accounts for such cost…
The study analyzes historical interest rates to predict future discount rates and their implications on climate change.
Optimal buying and selling times for homes in fluctuating interest rates.
In his book with Alan Jolis, Vers un monde sans pauvreté (1997) Yunus gives the example of a microcredit loan of 1000BDT reimbursed via 50 weekly settlements of 22BDT and correctly claims that this corresponds to the annual interest rate of 20%. But this is without taking into account that if the borrower has good reas…
The study examines how investor protection and past information affect stock returns and interest rates.
This paper examines the risk-adjusted performance and differential fund flows for socially responsible mutual funds (SRMF). The results show that SRMF rated high on ESG, perform better than lower rated ESG funds during the period of economic crisis. The findings also show that low ESG rated SRMF had higher differential…
In an incomplete continuous-time securities market with uncertainty generated by Brownian motions, we derive closed-form solutions for the equilibrium interest rate and market price of risk processes. The economy has a finite number of heterogeneous exponential utility investors, who receive partially unspanned income …
A semi-static approach efficiently replicates and prices callable interest rate derivatives.
Study on efficient estimation of Gaussian mean with limited communication.
The paper bounds neural networks' approximation error and applies it to regression and GANs.
New algorithms for private GLM estimation with minimax lower bounds.
In the context of dealing with financial risk management problems it is desirable to have accurate bounds for option prices in situations when pricing formulae do not exist in the closed form. A unified approach for obtaining upper and lower bounds for Asian-type options, including options on VWAP, is proposed in this …
There are more than eight hundred interest rates published in China bond market every day. Which are the benchmark interest rates that have broad influences on most interest rates is a major concern for economists. In this paper, multi-variable Granger causality test is developed and applied to construct a directed net…
Vanna-Volga is a popular method for the interpolation/extrapolation of volatility smiles. The technique is widely used in the FX markets context, due to its ability to consistently construct the entire Lognormal smile using only three Lognormal market quotes. However, the derivation of the Vanna-Volga method itself is …
Researchers prove inner product recovery is impossible in latent space models.
We give a detailed account of correlations between credit sector/quality and treasury curve factors, using the robust framework of the Barclays POINT Global Risk Model. Consistent with earlier studies, we find a strong negative correlation between sector spreads and rate shifts. However, we also observe that the correl…
This paper improves the convergence rates of bilevel optimization algorithms.
Study on asset price dynamics in OLG economies with and without a bubbly asset.
Improved fast rates for decision making with forward-KL regularization in contextual bandits.
In this paper, we consider a popular model for collaborative filtering in recommender systems where some users of a website rate some items, such as movies, and the goal is to recover the ratings of some or all of the unrated items of each user. In particular, we consider both the clustering model, where only users (or…
The study examines conditions for achieving a simple lower bound in estimating mean from samples.
Study on bending energy of surfaces with curvature concentration, deriving new lower bounds.
New bounds on KPCA efficiency reveal conditions for fast convergence.
News on inflation and monetary policy impacts US household inflation expectations.
Study on -function estimation for continuous state-action MDPs, deriving rates and conditions.
In this paper, we are concerned with the valuation of Guaranteed Annuity Options (GAOs) under the most generalised modelling framework where both interest and mortality rates are stochastic and correlated. Pricing these type of options in the correlated environment is a challenging task and no closed form solution exis…
This research improves DeFi interest rates using a PID control system.
Paper studies federated nonparametric testing with privacy constraints, achieving optimal rates and adaptive testing.
Recent successes of game-theoretic formulations in ML have caused a resurgence of research interest in differentiable games. Overwhelmingly, that research focuses on methods and upper bounds on their speed of convergence. In this work, we approach the question of fundamental iteration complexity by providing lower boun…
The present study deals with the analysis and mapping of Swiss franc interest rates. Interest rates depend on time and maturity, defining term structure of the interest rate curves (IRC). In the present study IRC are considered in a two-dimensional feature space - time and maturity. Geostatistical models and machine le…
Study proposes optimal risk-aware interest rates for crypto lending protocols.
Chronos models improve financial forecasting by integrating multivariate data.
This article is an extension of the work of one of us (Coopersmith, 2011) in deriving the relationship between certain interest rates and the inflation rate of a two component economic system. We use the well-known Fisher relation between the difference of the nominal interest rate and its inflation adjusted value to e…
This paper examines SVB's failure and its impact on bank stocks.
Developed unbiased estimators for Heston model with stochastic interest rates.
In this survey paper we discuss recent advances on short interest rate models which can be formulated in terms of a stochastic differential equation for the instantaneous interest rate (also called short rate) or a system of such equations in case the short rate is assumed to depend also on other stochastic factors. Ou…
