Realized Volatility and Long Memory: An Overview

The challenge of modeling, estimating, testing, and forecasting financial volatility is both intellectually worthwhile and also central to the successful analysis of financial returns and optimal investment strategies. In each of the three primary areas of volatility modeling, namely, conditional (or generalized autoregressive conditional heteroskedasticity) volatility, stochastic volatility and realized volatility (RV), numerous univariate volatility models of individual financial assets and multivariate volatility models of portfolios of assets have been established. This special issue has eleven innovative articles, eight of which are focused directly on RV and three on long memory, while two are concerned with both RV and long memory.

Circuits of architecture and urban planning: Professional ethos and the internationalization of small architectural offices

Although the production of the built environment is increasingly globalized, and architecture and urban planning (AUP) professionals are known to be the key carriers of mobile ideas, the internationalization of small owner-centred architectural offices has gained little academic attention, compared to the large consultancies that dominate the global market. We bring together the literature on the circuits of urban planning ideas, the international movement of AUP firms and professional ethoses to explore the internationalization of small AUP offices. Using interview data from Finnish offices, we investigate the ‘what, where, why and how’ and find that they have entered specific geographically delimited AUP circuits demarcated by type of project. We contribute to the literature by identifying motives characteristic of small offices guided by professional ethoses suited to the circuits where they internationalize. Their ethoses may evolve in time and space, as they operate in new circuits. We propose that ethos–circuit coherence may contribute to the successful internationalization of small architectural offices. The findings open avenues for further research on professional ethos not only of architects but also other internationally operating professionals, as it may guide their decisions by other than a narrowly conceived profit motive.
