In this paper we develop models for multivariate financial bubbles and antibubbles based on statistical physics. In particular, we extend a rich set of univariate models to higher dimensions. Changes in market regime can be explicitly shown to represent a phase transition from random to...

In this paper we provide a unifying framework for a set of seemingly disparate models for exogenous and endogenous shocks in complex financial systems. Markets operate by balancing intrinsic levels of risk and return. This remains true even in the midst of transitory external shocks. Changes in...

Amid its rapidly increasing usage and immense public interest the subject of Bitcoin has raised profound economic and societal issues. In this paper we undertake economic and econometric modelling of Bitcoin prices. As with many asset classes we show that Bitcoin exhibits speculative bubbles....

In this paper we provide a unifying framework for a set of seemingly disparate models for bubbles, shocks and elementary technical trading strategies in financial markets. Markets operate by balancing intrinsic levels of risk and return. This seemingly simple observation is commonly over-looked...

Proposals specifically aimed at delivering environmental benefits are often exempt from assessment, despite evidence that they can be poorly thought-through and sometimes counterproductive. This is doubly true of agri-environmental schemes where local farm-scale actions are expected to generate...

This paper looks at the changing concept of landscape during the evolution of REPS. It reviews and groups definitions of landscape and identifies their agri-environmental relevance. Descriptions were devised to amplify each grouping with reference to an Irish context and were used as an...

In this paper we develop models for multivariate financial bubbles and antibubbles based on statistical physics. In particular, we extend a rich set of univariate models to higher dimensions. Changes in market regime can be explicitly shown to represent a phase transition from random to...

We develop a rational expectations model of financial bubbles and study how the risk-return interplay is incorporated into prices. We retain the interpretation of the leading Johansen-Ledoit-Sornette model: namely, that the price must rise prior to a crash in order to compensate a representative...

Greening the Budget regards the fundamental cause of environmental degradation as government and market failure and proposes the use of budgets as an instrument of environmental policy to rectify this problem. The book focuses on the elements of the public budget which currently affect the...

In this paper we employ a Markov-Switching EGARCH model to investigate the dynamic linkage between stock price volatility and exchange rate changes for four emerging countries over the period 1994-2009. Results distinguish between two different regimes in both the conditional mean and the...
