Efficiency, Shadow Pricing and Regime Switching in Multi‐Ware Technologies: Evidence From Regulated Livestock Farms

open access: yesJournal of Agricultural Economics, EarlyView.
ABSTRACT We develop a framework for regulated production systems where output generation and pollution abatement impose competing technological demands. Using a multi‐ware technology, we model the production set as the intersection of two input requirement frontiers, one for production and one for abatement, each reflecting distinct trade‐offs.

Improved Nonparametric Density Estimation Using Additive Kernel Estimators

open access: yes
One way of improving the rate of convergent of classical kernel estimator is to use higher –order kernel function. In this thesis suggests anew” additive kernel estimator” to estimate f(x) , the proposed estimator are simple and interpretable as the higher –order estimator .

Mitigating policy uncertainty: What financial markets reveal about firm‐level lobbying

open access: yesAmerican Journal of Political Science, EarlyView.
Abstract Elections can lead to substantial policy changes and, thus, are a significant source of risk. Firms can respond to such policy uncertainty by lobbying, but it is hard to quantify whether they do so and, if so, how much lobbying benefits them. We construct a new dataset and leverage investors’ expectations of variability in stock returns in the

DESIGN-ADAPTIVE POINTWISE NONPARAMETRIC REGRESSION ESTIMATION FOR RECURRENT MARKOV TIME SERIES [PDF]

open access: yes
A general framework is proposed for (auto)regression nonparametric estimation of recurrent time series in a class of Hilbert Markov processes with a Lipschitz conditional mean.

ReMoDe – Recursive modality detection in distributions of ordinal data

open access: yesBritish Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract The detection of the number of modes in distributions of ordinal data is relevant for applied researchers across disciplines, from uncovering polarization to detecting incidence groups in clinical symptom scales. Yet, established modality detection methods are either purely descriptive or not developed for ordinal data.

Feasible Multivariate Nonparametric Estimation Using Weak Separability [PDF]

open access: yes
One of the main practical problems of nonparametric regression estimation is the curse of dimensionality. The curse of dimensionality arises because nonparametric regression estimates are dependent variable averages local to the point at which the ...

Nonparametric option pricing with no-arbitrage constraints [PDF]

open access: yes
We propose a completely kernel based method of estimating the call price function or the state price density of options. The new estimator of the call price function fulfills the constraints like monotonicity and convexity given in Breeden and ...

Biogeography of Atlantic Salmon in the Cape Breton Highlands, Canada

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT Atlantic Salmon (Salmo salar) populations have experienced significant declines in recent decades. In Canada, conservation efforts are divided into 16 designatable units (DUs) to address unique regional challenges among genetically distinct populations.
