A Non‐parametric Estimation of Productivity with Idiosyncratic and Aggregate Shocks: The Role of Research and Development (R&D) and Corporate Tax

I Bournakis, M Tsionas - Oxford Bulletin of Economics and …, 2024 - Wiley Online Library
We develop a non‐parametric technique framework for estimating firm‐level Total Factor
Productivity (TFP). Our paper has two major novelties: first, we propose a modelling of …

Productivity and Performance: A GMM approach

MG Tsionas, SC Kumbhakar - Oxford Bulletin of Economics and …, 2023 - Wiley Online Library
In this paper we propose a single‐step generalized method of moments (GMM) approach to
estimate a production function with multiple quasi‐fixed and variable inputs as well as …

Gaussian processes and Bayesian moment estimation

JP Florens, A Simoni - Journal of Business & Economic Statistics, 2021 - Taylor & Francis
Given a set of moment restrictions (MRs) that overidentify a parameter θ, we investigate a
semiparametric Bayesian approach for inference on θ that does not restrict the data …

Downside risk and portfolio optimization of energy stocks: A study on the extreme value theory and the vine copula approach

M Karmakar, S Paul - The Energy Journal, 2023 - journals.sagepub.com
Energy stocks are potentially a hedge against inflation and have a number of advantages
over other forms of energy investing. This motivates us to study on portfolio management of …

Endogenous efficiency of the dynamic profit maximization in the intertemporal production models of venture behavior

M Tsionas, PC Patel, MJ Guedes - International Journal of Production …, 2022 - Elsevier
How do ventures manage adjustment costs, input elasticities, and productivity growth? We
draw on the intertemporal production decisions of ventures that are quasi-fixed, costly to …

Measures of global sensitivity in linear programming: Applications in banking sector

MG Tsionas, D Philippas - Annals of Operations Research, 2023 - Springer
The paper examines the sensitivity for the solution of linear programming problems using
Bayesian techniques, when samples for the coefficients of the objective function are …

Instrumental Variables Inference in a Small-Dimensional VAR Model with Dynamic Latent Factors

F Carlini, P Gagliardini - Econometric Theory, 2022 - cambridge.org
We study semiparametric inference in a small-dimensional vector autoregressive (VAR)
model of order p augmented by unobservable common factors with a dynamic described by …

Efficiency measurement in Norwegian electricity distribution: A generalized four-way-error-component stochastic frontier model

MG Tsionas, SC Kumbhakar - The Energy Journal, 2023 - journals.sagepub.com
In this paper, we introduce a new model to estimate efficiency by generalizing the state-of-
the-art panel stochastic frontier model, the salient feature of which is decomposition of …

Inflation Target at Risk: A Time-varying Parameter Distributional Regression

Y Wang, T Oka, D Zhu - arXiv preprint arXiv:2403.12456, 2024 - arxiv.org
Macro variables frequently display time-varying distributions, driven by the dynamic and
evolving characteristics of economic, social, and environmental factors that consistently …

Endogenous dynamic efficiency in the intertemporal optimization models of firm behavior

MG Tsionas, E Malikov, SC Kumbhakar - European Journal of Operational …, 2020 - Elsevier
