Vector autoregressive (VAR) models are among the most widely used econometric tools in the fields of macroeconomics and financial economics. Much of what we know about the response of the economy to macroeconomic shocks and about how various shocks have contributed to the evolution of macroeconomic and financial aggregates is based on VAR models. VAR models also have been used successfully for economic and business forecasting, for modelling risk and volatility, and for the construction of forecast scenarios. Since the introduction of VAR models by C.A. Sims in 1980, the VAR methodology has continuously evolved. Even today important extensions and reinterpretations of the VAR framework are being developed. Examples include VAR models for mixed-frequency data, VAR models as approximations to DSGE models, factor-augmented VAR models, new tools for the identification of structural shocks in VAR models, panel VAR approaches, and time-varying parameter VAR models. This volume collects contributions from some of the leading VAR experts in the world on VAR methods and applications. Each chapter highlights and synthesizes a new development in this literature in a way that is accessible to practitioners, to graduate students, and to readers in other fields.

Ireland is home to some of the world’s oldest astronomically-aligned structures, giant stone monuments erected over 5,000 years ago. Despite their apparent simplicity, these megalithic edifices were crafted by a scientifically knowledgeable community of farmers who endeavoured to enshrine their beliefs in a stellar afterlife within the very fabric of their cleverly-designed stone temples. Finally back in print, this reissued edition presents evidence suggesting the builders of monuments such as Newgrange and its Boyne Valley counterparts were adept astronomers, cunning engineers and capable surveyors. Their huge monuments are memorials in stone and earth, commemorating their creators’ perceived unity with the cosmos and enshrining a belief system which resulted from a crossover between science and spirituality. As investigation of this awe-inspiring civilisation of people continues on many levels, evidence is emerging that significant archaeological sites dating from deep in prehistory are linked – not just through mythology, archaeology and cosmology – but through an arrangement of complex, and in some cases astonishing, alignments. Some of these alignments of ancient sites stretch from one side of Ireland to another.While the accounts of the lives of some prominent Irish saints appear to be steeped in folklore and mystery, it seems from new interpretations of the literature that the cosmic world view which existed in Neolithic Ireland experienced a continuity right into the Early Christian period. Join us on this fascinating exploration of stones, stars and stories. "The sheer amount of information contained within the book is mind-boggling. It is well thought out and structured… The more you read the evidence the more convinced you become." – Astronomy& Space magazine "Refreshing and fascinating . . . a wonderful magical book, sumptuously illustrated and a must for anyone who loves to delve deep into our past." – Kenny’s Irish Bookshop "A fascinating insight into Ireland’s ancient burial sites" – Irish Independent "A monument" – Drogheda Independent “It is a beautiful book and very well written. The information that you collected is outstanding.” – Barbara Carter, co-author, The Myth of the Year and The Goddess and the Bull “The authors… reach interesting and challenging conclusions about the significance of ancient astronomical knowledge. The book is jammed with colour illustrations, maps and photographs. A thoroughly interesting read!” – Archaeology Ireland "An essential book that demonstrates just how much the beliefs and practices of our ancestors were influenced by the movement of the stars, in particular those of the constellation Cygnus - the celestial swan and Northern Cross - once seen as a source of life and the destination of the soul in death. A must have tome for all those passionate about what remains of our fast disappearing ritual monuments of the prehistoric age." - Andrew Collins, author of The Cygnus Mystery
