Moving Aggregate Modified Autoregressive Copula‐Based Time Series Models (MAGMAR‐Copulas)
Journal of Time Series Analysis, EarlyView.ABSTRACT Copula‐based time series models can model univariate and stationary time series in a flexible way by decomposing the joint distribution of consecutive observations into a copula and the stationary distribution. Implicitly, this approach assumes a finite Markov order. In reality, a time series may not follow the Markov property.

FKG inequality for Levy processes and SDE
reservedThe Fortuin-Kasteleyn-Ginibre inequality is a famous correlation inequality in measure theory. In this thesis our goal is to provide sufficient conditions for the validity of the FKG inequality in probabilistic contexts.

ON THE RELATIONSHIPS BETWEEN SPATIAL CLUSTERING, INEQUALITY, AND ECONOMIC GROWTH IN THE UNITED STATES : 1969-2000 [PDF]
The literature on economic development has been divided as to the nature of the relationship between inequality and growth. Recent exploratory work in the field has provided evidence that the dynamic and spatial relationships between the two may be far ...

LABOUR, EarlyView.ABSTRACT Advances in artificial intelligence (AI) and robotics since 2000 led to widespread concern that automation would eliminate a massive number of jobs. Frey and Osborne's influential study concluded AI and robots might eliminate nearly half of all US jobs between 2010 and 2030.

A behaviorally-based approach to measuring inequality [PDF]
The measurement of inequality is often made using observed population-based distributions, such as the distribution of income or the distribution of members of different groups across neighborhoods. Unfortunately, such distributions confound the behavior

Measure‐valued processes for energy markets
Mathematical 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 ...

REGIONAL INCOME INEQUALITY AND URBANISATION TRENDS IN CHINA: 1978-2005 [PDF]
A long-standing economic literature has delivered rich empirical evidence on the relationship between economic growth and income inequality or urbanisation, since Simon Kuznets’ pioneering work on the inverted U curve hypothesis.

Reinforcement Learning for Jump‐Diffusions, With Financial Applications
Mathematical Finance, EarlyView.ABSTRACT We study continuous‐time reinforcement learning (RL) for stochastic control in which system dynamics are governed by jump‐diffusion processes. We formulate an entropy‐regularized exploratory control problem with stochastic policies to capture the exploration–exploitation balance essential for RL.

Inequality and Public Policy: A Country Study for Bulgaria [PDF]
This paper is an attempt for measuring the impact of public policy on the inequality in Bulgaria. An analysis based on the Bulgarian Household Budget Surveys shows that the tax burden in Bulgaria, nevertheless increasing in the upper quintiles, declined ...

Never, Ever Getting Started: On Prospect Theory Without Commitment
Mathematical Finance, EarlyView.ABSTRACT Prospect theory is arguably the most prominent alternative to expected utility theory. We study the investment or gambling behavior of a prospect theory decision maker who is aware of his time‐inconsistency but lacks commitment. For the empirically relevant prospect theory specifications, we obtain the extreme prediction that such a decision ...
