Abstract

This paper compares the out-of-sample forecasting performance of three long-memory volatility models (i.e., fractionally integrated (FI), break and regime switching) against three short-memory models (i.e., GARCH, GJR and volatility component). Using S&P 500 returns, we find that structural break models produced the best out-of-sample forecasts, if future volatility breaks are known. Without knowing the future breaks, GJR models produced the best short-horizon forecasts and FI models dominated for volatility forecasts of 10 days and beyond. The results suggest that S&P 500 volatility is non-stationary at least in some time periods. Controlling for extreme events (e.g., the 1987 crash) significantly improved forecasting performance.

Abstract

This chapter extracts a broad range of learning situations in connection with product innovation. The data comprise interviews with the management and employees in five Danish manufacturing firms visited during 2000–2001. Among important learning situations and factors promoting learning have been found the firms’ contacts with customers, project leaders’ cross functional coordinating activities, and cooperation with suppliers and knowledge institutions. The restraints upon learning comprise inter alia strategic patterns, tight time planning, old routines and communication difficulties, changing of roles, ad hoc decisions on training and education and some times among employees lack of motivation. Some policy perspectives are outlined.

Abstract

In the twenty-first century, societies around the world are facing a wide range of daunting global mega-challenges: poverty, unemployment, income inequality, unequal distribution of political power, ageing populations, uncontrolled migration, segregated urbanisation, increasing greenhouse gas emissions and a massive decrease in biodiversity. In recent years, politicians, journalists and academic observers have singled out the Nordic countries, Denmark in particular, as model societies of trusting and happy people that have handled many of these challenges with remarkable effectiveness. And yet others warn against ‘becoming Denmark,’ painting a picture of a dysfunctional, socialist nightmare with high taxes, low job motivation and a general lack of private initiative. In this introductory chapter, the editors cut through the noise of the international debate and set the scene for the nuanced analyses presented here of contemporary public governance in Demark and its capacity to tackle some of the most pressing problems of our time. Specifically, the chapter discusses various conceptualisations of the Danish welfare state, delineates some of its most important historical and structural traits and outlines the main empirical features of contemporary Danish public governance. Finally, it outlines the structure of the book and briefly introduces each of its subsequent chapters.
