An important aspect of the banking system is the network of exposures between individual financial institutions. Using regulatory data, this article maps the network of large bilateral exposures between Australian financial institutions and then analyses its basic features using the tools of...

Matrices have a lot of applications in all areas of human endeavour. In fact, the use of matrices in modelling engineering networks has made matrices an essential part of research in the fields of science and engineering. In this paper, we used nodal and mesh incidence matrices to construct...

Research on entrepreneurial networking could be regarded as an area of entrepreneurship where research has developed at a much lower pace than in entrepreneurship in general. The reasons for this phenomenon could be that researchers either avoided the area or were discouraged by an array of...

Infrastructures, such as plant and services that are critical for the safe and nominal operation of society can be loosely defined as ‘critical infrastructures’ and can take on many different forms e.g. sectoral such as transport systems or components such as high-voltage power lines. The...

In this paper we use weekly milling wheat price series for nine selected EU countries to evaluate levels and components of volatility in the period from July 2004 to April 2011 and to examine how sensitive the results can be to spatial aggregation of the price data. The prices were analyzed in...

Simulation methods are used to measure the expected differentials between the Mean Square Errors of the forecasts from models based on temporally disaggregated versus aggregated data. This allows for novel comparisons including long-order ARMA models, such as those expected with weekly data,...

We investigate biases in farm-level yield risk analysis caused by data aggregation from the farm-level to regional and national levels using the example of Swiss wheat and barley yields. The estimated yield variability decreases significantly with increasing level of aggregation, with crop yield...

From 1980-2009 the Polish economy experienced structural dislocation. The growth and success of the Solidarity movement represented the shift in manufacturing from Soviet bloc trade to membership in the European Union. This paper examines four independent metrics that measure the changing...
