Sparse Causal Dynamic Linear Regression

open access: yesJournal of Time Series Analysis, EarlyView.
ABSTRACT We develop a sparse causal dynamic regression framework for long multivariate time series. With very long time series, the potentially large number of lags and leads in a dynamic regression model often makes time‐domain estimation numerically unstable or intractable.

Influence and convergence to higher standards: The dual examination of pharmaceutical patents in Brazil

open access: yesThe Journal of World Intellectual Property, EarlyView.
Abstract Between 2001 and 2021, pharmaceutical patent applications filed in Brazil were examined by the patent office (INPI) and the national health regulator (Anvisa). This paper investigates how health regulators can contribute to patent examination by shifting the set of criteria cited as grounds for 2589 negative decisions from both entities ...

Assessing Digital Interactional Competence for Second‐Language and First‐Language Chinese Speakers: Effects of Proficiency, Mode, and Setting

open access: yesLanguage Learning, EarlyView.
Abstract Measurement of interactional competence (IC) has attracted increasing interest in language assessment research. One key question is whether proficiency sufficiently accounts for IC, making separate IC assessment unnecessary. This study examines the IC–proficiency relationship using a test that assesses Chinese speakers’ ability to manage ...

Stochastic Dominance Efficiency Tests under Diversification [PDF]

open access: yes
This paper focuses on Stochastic Dominance (SD) efficiency in a finite empirical panel data. We analytically characterize the sets of unsorted time series that dominate a given evaluated distribution by the First, Second, and Third order SD.

Measure‐valued processes for energy markets

open access: yesMathematical Finance, Volume 35, Issue 2, Page 520-566, April 2025.
Abstract We introduce a framework that allows to employ (non‐negative) measure‐valued processes for energy market modeling, in particular for electricity and gas futures. Interpreting the process' spatial structure as time to maturity, we show how the Heath–Jarrow–Morton approach can be translated to this framework, thus guaranteeing arbitrage free ...

The fundamental theorem of asset pricing with and without transaction costs

open access: yesMathematical 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 ...

Minimax Estimation of Linear Combinations of Restricted Location Parameters

open access: yes, 2010
The estimation of a linear combination of several restricted location parameters is addressed from a decision-theoretic point of view. A bench-mark estimator of the linear combination is an unbiased estimator, which is minimax, but inadmissible relative ...
