Using the capital asset pricing model, this article critically assesses the relative importance of computing 'realized' betas from high-frequency returns for Bitcoin and Ethereum-the two major cryptocurrencies-against their classic counterparts using the 1-day and 5-day return-based betas. The...

This paper primarily reviews the panel stochastic frontier (SF) model in which the composite error term εit has four components, i.e. εit=τi−ηi+vit−uit, where ηi and uit are the persistent and transient inefficiency components, τi is the random firm effect and vit is the random noise....

A general assumption of the standard hedonic price model is that producers produce outputs/ services efficiently, and deviations from this situation are assumed to involve either overcharging or undercharging. Using the profit maximising behaviour, we derive an alternative hedonic model to show...

This paper discusses and illustrates the analytical foundations of international comparisons (or benchmarking) for assessing a country's potential for improvement along various dimensions of social and economic development. By providing a methodology for international benchmarking, discussing...

This paper investigates the convergence behaviour of carbon dioxide emissions for 39 countries in the Americas from 1960-2016. A linear regression test of convergence which looks for conditional sigma convergence is employed, and a clustering algorithm is used to identify convergence clubs. The...

This paper does an empirical comparison of time-invariant and time-varying technical inefficiency measures obtained from an econometric estimation of different panel data stochastic production frontier models. It estimates four panel data specifications of frontier models widely used in...
