This Occasional Paper examines how and why the institutional framework governing EMU has evolved since the creation of the euro. Building on theories of institutionalism, the paper in particular investigates to what extent functional spillovers from the single currency into other policy domains,...

Our main contention is that two different re-conceptualizations of liberal democracy took place among Chicago economists in the postwar period. The first emerged out of Frank H. Knight's ruminations in the 1930s on the failures of liberalism. By the 1940s, Knight devoted most of his attention to...

Search engine query data deliver insight into the behavior of individuals who are the smallest possible scale of our economic life. Individuals are submitting several hundred million search engine queries around the world each day. We study weekly search volume data for various search terms from...

It is well-known that financial asset returns exhibit fat-tailed distributions and long-term memory. These empirical features are the main objectives of modeling efforts using (i) stochastic processes to quantitatively reproduce these features and (ii) agent-based simulations to understand the...

For an intriguing variety of switching processes in nature, the underlying complex system abruptly changes from one state to another in a highly discontinuous fashion. Financial market fluctuations are characterized by many abrupt switchings creating upward trends and downward trends, on time...

We introduce a simple model for simulating financial markets, based on an order book, in which several agents trade one asset at a virtual exchange continuously. For a stationary market the structure of the model, the order flow rates of the different kinds of order types and the used price time...

The compute unified device architecture is an almost conventional programming approach for managing computations on a graphics processing unit (GPU) as a data-parallel computing device. With a maximum number of 240 cores in combination with a high memory bandwidth, a recent GPU offers resources...

Understanding correlations in complex systems is crucial in the face of turbulence, such as the ongoing financial crisis. However, in complex systems, such as financial systems, correlations are not constant but instead vary in time. Here we address the question of quantifying state-dependent...

We introduce a future orientation index to quantify the degree to which Internet users worldwide seek more information about years in the future than years in the past. We analyse Google logs and find a striking correlation between the country's GDP and the predisposition of its inhabitants to...

The issue of the stability and change of legal rules occupies a central place in the discussions of alternative ways of organizing justice and the provision of legal rules. There nonetheless remains a theoretical aspect that has never been raised in the literature on judicial decision making and...
