It is easy to demonstrate that Sen's SWF satisfies Pareto criteria. This paper questions the philosophy of this concept and shows that it is possible to formulate a generalized SWF, which can be non-Paretian under special circumstances. This paper also demonstrates a method of decomposition of...

Composite models have received much attention in the recent actuarial literature to describe heavy-tailed insurance loss data. One of the models that presents a good performance to describe this kind of data is the composite Weibull-Pareto (CWL) distribution. On this note, this distribution is...

This paper examines the shape of the firm size distribution over time and across sectors, using a longitudinal data set of manufacturing firms in the Netherlands in 1978-1998. Although the size distribution is highly skewed and resembles the Pareto law, a variety of patterns emerge across...

This paper analyses the performance of the graphs traditionally used to study size distributions: histograms, Zipf plots (double logarithmic graphs of rank compared to size) and plotted cumulative density functions. A lognormal distribution is fitted to urban data from three countries (the US,...

The Zipf analysis of n-words in random sequences and financial data series like the stock prices of a company has been performed. The bias as well as the resulting staircase structure of the Zipf plots are taken into account in the subsequent analysis. It is found that correlations for the sign...

Using a simple stochastic growth model, this paper demonstrates that the coefficient of variation of aggregate output or GDP does not necessarily go to zero even if the number of sectors or economic agents goes to infinity. This phenomenon known as non-self-averaging implies that even if the...

A large market economy has a huge number of degrees of freedom with weak microlevel coordination. The 'implicit microfoundations' approach assumes this property of micro-level interactions more strongly conditions macro-level outcomes compared to the precise details of individual choice...
