CBDC as Imperfect Substitute to Bank Deposits: A Macroeconomic Perspective
Journal of Money, Credit and Banking, EarlyView.Abstract The impact of Central Bank Digital Currency (CBDC) is analyzed in a closed‐economy model with monopolistic competition in banking and where CBDC is an imperfect substitute with bank deposits. The design of CBDC is characterized by its interest rate, its substitutability with bank deposits, and its relative liquidity.

On Thévenaz' parametrization of interiorG-algebras
Mathematische Zeitschrift, 1994 We give a complete proof of the parametrization of primitive interior \(G\)-algebras by the \(G\)-conjugacy classes of triples \((P,B,V)\) formed by a defect group \(P\), a \(P\)-source algebra \(B\) and a \((P,B)\)-multiplicity module \(V\), more or less suggested in Lemma 9.9 and Remarks 9.10 and 9.11 in an earlier paper [J. Algebra 116, No. 1, 7-129

The Journal of Finance, EarlyView.ABSTRACT We introduce the concept of subtle discrimination—biased acts that cannot be objectively ascertained as discriminatory. When candidates compete for promotions by investing in skills, firms' subtle biases induce discriminated candidates to overinvest when promotions are low‐stakes (to distinguish themselves from favored candidates) but ...

Tests for Changes in Count Time Series Models With Exogenous Covariates
Journal of Time Series Analysis, EarlyView.ABSTRACT We deal with a parametric change in models for count time series with exogenous covariates specified via the conditional distribution, i.e., with integer generalized autoregressive conditional heteroscedastic models with covariates (INGARCH‐X).

On the preservation of unification type of Heyting algebras and interior algebras
The purpose of this note is to shed some light on the preservation of unification types of locally finite varieties of interior algebras and varieties of Heyting algebras under the functors presented by W. Blok in his dissertation.

Tensor Changepoint Detection and Eigenbootstrap
Journal of Time Series Analysis, EarlyView.ABSTRACT Tensor data consisting of multivariate outcomes over the items and across the subjects with longitudinal and cross‐sectional dependence are considered. A completely distribution‐free and tweaking‐parameter‐free detection procedure for changepoints at different locations is designed, which does not require training data.

The fundamental theorem of asset pricing with and without transaction costs
Mathematical Finance, Volume 35, Issue 2, Page 567-609, April 2025.Abstract We prove a version of the fundamental theorem of asset pricing (FTAP) in continuous time that is based on the strict no‐arbitrage condition and that is applicable to both frictionless markets and markets with proportional transaction costs. We consider a market with a single risky asset whose ask price process is higher than or equal to its ...

Macroscopic Market Making Games
Mathematical Finance, EarlyView.ABSTRACT Building on the macroscopic market making framework as a control problem, this paper investigates its extension to stochastic games. In the context of price competition, each agent is benchmarked against the best quote offered by the others. We begin with the linear case.

On defect groups of interior G-algebras and vertices of modules
Hokkaido Mathematical Journal, 1990 Let \(G\) be a finite group, and let \({\mathcal O}\) be a complete discrete valuation ring with algebraically closed residue field of characteristic \(p\neq 0\). Recall that an interior \(G\)-algebra over \({\mathcal O}\) is a pair consisting of an \({\mathcal O}\)-order \(A\) and a unitary homomorphism \(\rho: {\mathcal O}G\to A\).
