In machine learning and data science literature, clustering is the task of dividing the observations (data points) into several categories in such a way that data points falling into one group are being dissimilar than the data points falling to the other groups such that the variation within a...

This paper describes the impact caused by immigration on the estimated growth of gross domestic product per capita (GDPpc) in each of the countries of the 15 members of the European Union (EU-15) during the period 1995 to 2013. Specifically, GDPpc breaks down into three factors: labour...

Despite of the recognized importance on the explicitation of knowledge within knowledge management, this process has been mainly studied from the internal perspective. That is, considering only the workers as explicit actors, leaving aside that the sources of knowledge are often external actors....

An information transaction entails the purchase of information. Formally, it consists of an information structure together with a price. We develop an index of the appeal of information transactions, which is derived as a dual to the agent's preferences for information. The index of information...

The persistent nature of equity volatility is investigated by means of a multi-factor stochastic volatility model with time varying parameters. The parameters are estimated by means of a sequential matching procedure which adopts as auxiliary model a time-varying generalization of the HAR model...

Cultural diversity - in various forms - has in recent years turned into a prominent and relevant research and policy issue. There is an avalanche of studies across many disciplines that measure and analyse cultural diversity and its impacts. Based on different perspectives and features of the...

For most European Union countries the government expenditure exceeds government revenue which could lead in the long run to an increase in the government debt to GDP ratio. Considering the distortions generated by the financial and economic crisis, followed by the debt crisis, both local and...

The level of disposable income inequality in Israel has increased noticeably since the mid-1980s and today it is above most developed countries. In contrast, market income inequality, which hit a record level in 2002, has reversed its course since then and has shown a sharp decline in subsequent...

We develop an efficient and easy-to-use computational method for solving a wide class of general equilibrium heterogeneous agent models with aggregate shocks, together with an open source suite of codes that implement our algorithms in an easy-to-use toolbox. Our method extends standard...

Until recently, theorists considering the evolution of human cooperation have paid little attention to institutional punishment, a defining feature of large-scale human societies. Compared to individually-administered punishment, institutional punishment offers a unique potential advantage: the...
