We prove a uniform ergodic theorem for expectiles that implies the pointwise ergodic theorem in one special case. The converse is also true: we show that uniform convergence of expectile functions is implied by the pointwise ergodic theorem

The aim of the article is to verify a hypothesis on the occurrence of spatial interactions in foreign migrations in selected European cities by applying different spatial weights matrices that define the multidimensional spatial dependences. The analysis used GIS, ESDA, geostatistical, spatial...

This paper considers a class of GMM estimators for general dynamic panel models, allowing for cross sectional dependence due to spatial lags and due to unspecified common shocks. We significantly expand the scope of the existing literature by allowing for endogenous spatial weight matrices,...

Spatial econometrics has recently been appraised in a theme issue of the Journal of Regional Science. Partridge et al. (2012) provide an overview of the three contributing papers, the most critical being Gibbons and Overman (2012). Although some of the critiques raised are valid, they are issues...

There is a large theoretical literature on methods for estimating causal effects under unconfoundedness, exogeneity, or selection-on-observables type assumptions using matching or propensity score methods. Much of this literature is highly technical and has not made inroads into empirical...

Following the recent work of Gómez-Déniz and Pérez-Rodríguez (2014), this paper extends the results obtained there to the normal-exponential distribution with dependence. Accordingly, the main aim of the present paper is to enhance stochastic production frontier and stochastic cost frontier...

The paper focuses on the issue of the modifiable areal unit problem (MAUP), which is frequently discussed within spatial econometrics. This issue concerns the changeability of the characteristics of the analysed phenomena under the impact of the change in the composition of territorial units...

The paper focuses on the issue of the aggregation problem which is frequently discussed within spatial econometrics. Aggregation problem is one of two aspects of the modifiable areal unit problem (MAUP). The aggregation problem is connected with the volatility of the obtained results occurred...

The paper focuses on the issue of the modifiable areal unit problem, which means a possibility of obtaining various results for spatial economic analyses depending on the assumed composition of territorial units. The major research objective of the work is to examine the scale problem that...

A new and rapidly growing econometric literature is making advances in the problem of using machine learning (ML) methods for causal inference questions. Yet, the empirical economics literature has not started to fully exploit the strengths of these modern methods. We revisit influential...
