Creative‐class dynamics, technological evolution and growth

Economica, EarlyView.
Abstract This paper investigates the impact of creativity on technological advancement, long‐term economic development, and social welfare, where creativity is determined endogenously through interactions within social networks. The analysis shows that an economy remains stagnant, exhibiting neither networking nor long‐term growth, when the size of the

The Augmented Hat‐Matrix of Hierarchical Generalised Linear Models and Its Use in Leverage Diagnostics

International Statistical Review, EarlyView.
Summary Defining a ‘hat‐matrix’ for a model is essential in many model diagnostic procedures, as it acts as an orthogonal projector from the observation space to the model space. In this paper, we introduce a unique Hat‐matrix for the class of hierarchical generalised linear models (HGLMs), which includes, as a special case, the subclass of generalised

The Cost of Convenience: A Hedonic Approach to Travel Time Valuation and Cost‐Benefit Analysis

Journal of Regional Science, EarlyView.
ABSTRACT This paper presents a novel revealed‐preference approach to estimating the value of travel time (VTT) and calculating consumer surplus for the economic evaluation of transport infrastructure. Departing from traditional stated‐preference models, we derive time valuations by linking residential rental transactions in Greater Sydney to employment

The Great British Productivity Puzzle and Regional Industries: A Dynamic Multilevel Spatial Frontier Analysis

Journal of Regional Science, EarlyView.
ABSTRACT Using two approaches, we contribute to sub‐national economic performance measurement by netting out the influence of a region's performance on its industries. The first approach measures performance using technical efficiency and involves introducing the first multilevel spatial stochastic frontier model.

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.
