Russia's agriculture: eight years in transition - convergence or divergence of regional efficiency

Uvarovsky, Vladimir; Voigt, Peter - 2000

In this paper, we consider how Russian Agriculture has developed since the constitution of the Russian Federation. The … efficiency (TE), technological change, and (both aggregated as overall index) on Total Factor Productivity (TFP). Given that the … agriculture is for many regions the fundamental source of income this fact is alarming, especially when the local agriculture …

Technical efficiency and its determinants of rice production in Cambodia

Kea, Sokvibol; Li, Hua; Pich, Linvolak - In: Economies 4 (2016) 4, pp. 1-17

The present study aims to measure the technical efficiency and establish core factors affecting rice production in Cambodia. A four-year dataset generated from the central government document 'Profile on Economics and Social' of 25 entire provinces between 2012 and 2015 and the stochastic...

A comparison of Bayesian and frequentist variable selection methods for estimating average treatment effects in logistic regression

Martinez, Alex H.; Christensen, Brian; Sutton, Elizabeth F. - 2025

In many manuscripts, researchers use multivariable logistic regression to adjust for potential confounding variables when estimating a direct relationship of a treatment or exposure on a binary outcome. After choosing how variables are entered into that model, researchers can calculate an...

The bayesian additive classification tree applied to credit risk modelling

Zhang, Junni L.; Härdle, Wolfgang Karl - 2008

We propose a new nonlinear classification method based on a Bayesian sum-of-trees model, the Bayesian Additive Classification Tree (BACT), which extends the Bayesian Additive Regression Tree (BART) method into the classification context. Like BART, the BACT is a Bayesian nonparametric additive...

Modeling House Prices using Multilevel Structured Additive Regression

Brunauer, Wolfgang; Lang, Stefan; Umlauf, Nikolaus - 2010

This paper analyzes house price data belonging to three hierarchical levels of spatial units. House selling prices with associated individual attributes (the elementary level-1) are grouped within municipalities (level-2), which form districts (level-3), which are themselves nested in counties...

Multivariate Stochastic Volatility via Wishart Processes - A Continuation

Rinnergschwentner, Wolfgang; Tappeiner, Gottfried; … - 2011

This paper picks up on a model developed by Philipov and Glickman (2006) for modeling multivariate stochastic volatility via Wishart processes. MCMC simulation from the posterior distribution is employed to fit the model. However, erroneous mathematical transformations in the full conditionals...

The R-package MitISEM: Efficient and Robust Simulation Procedures for Bayesian Inference

Basturk, Nalan; Grassi, Stefano; Hoogerheide, Lennart; … - 2015

This paper presents the R-package MitISEM (mixture of t by importance sampling weighted expectation maximization) which provides an automatic and flexible two-stage method to approximate a non-elliptical target density kernel -- typically a posterior density kernel -- using an adaptive mixture...

GMM estimation of affine term structure models

Hlouskova, Jaroslava; Sögner, Leopold - 2015

This article investigates parameter estimation of affine term structure models by means of the generalized method of moments. Exact moments of the affine latent process as well as of the yields are obtained by using results derived for p-polynomial processes. Then the generalized method of...

Empirical methods for the law

Engel, Christoph - 2017

To their credit, empirical legal scholars try to live up to the highest methodological standards from the social sciences. But these standards do not always match the legal research question. This paper focuses on normative legal argument based on empirical evidence. Whether there is a normative...
