The innovation systems (IS) approach — developed by Richard Nelson, Christopher Freeman and Bengt-Ake Lundvall, amongst others — has become perhaps the dominant approach in the academic literature for the study of innovation. It has also exerted considerable influence on policy. This paper...

The aim of this paper is to develop a continuous time exchange rate model that allows for heterogeneity of the agents' beliefs, in order to explore non-linearities and possible chaotic behaviour. The theoretical model contains an intrinsic non-linearity that gives rise to a jerk differential...

The classical theory about foreign exchange rate explains its fluctuations as the resulting of a random walk motion. In this paper, such a theory is put into question by performing Brock, Dechert and Scheinkman's (1987) test on the Austrian Schilling - US Dollars exchange rate for the period...

The US time structure of production during the 2002 through 2009 business cycle is characterized empirically using industry-level input-output data. An industry’s total industry output requirement (TIOR) is proposed as a metric for "roundaboutness". I find that the time structure of production...

This paper analyses the nature of knowledge spillovers from research and development (R&D) in the field of liquid crystal display technology by estimating the impact of inventors' changing organizational and collaborative affiliations on the probability of citations in US patents filed between...
