In linear-quadratic control (LQC) problems with singular control cost matrix and/or singular transition matrix, we derive a reduction of the dimension of the Riccati matrix, simplifying iteration and solution. Employing a novel transformation, we show that, under a certain rank condition, the...

Economic activities becoming more knowledge oriented. With liberalization of the global trade global competition escalated. In this context global competition acquired a shape among the knowledge goods. Societies which produce and use knowledge goods in their economic activities holding an...

This paper presents a model of collusion in vertically differentiated industries where firms have the option to make their products distinguishable to consumers by attaching a brand. We show that if consumers’ preferences are linear in the quality dimension and their beliefs satisfy a standard...

Referring (euphemistically) to Romania, the figures from the national reports which depict innovation are not particularly joyful – see Dumitrachi (2006), INS (2010), INS (2011), TBUI (2011), ANCS (2012), and Radu (2012). In this paper, we discuss the situation of the knowledge flows as...

This research considers the strategies on the initial public offering of company equity at the stock exchanges in the imperfect highly volatile global capital markets with the nonlinearities. We provide the IPO definition and compare the initial listing requirements on the various markets. We...

This paper reports on the design of a novel two-stage mechanism, based on strictly proper scoring rules, that allows a centre to acquire a costly probabilistic estimate of some unknown parameter, by eliciting and fusing estimates from multiple suppliers. Each of these suppliers is capable of...

The present paper proposes a new way of thinking regarding the relation between innovation and knowledge using a Physics-borrowed model, trying to prove whether knowledge resources can „flow” (be percolated) in a network or a grid, in order to be transformed in technological innovation. In...

The paper covers the significance of Lingua franca not only as a language of intercultural communications, but also as a necessary component of the adequate satisfaction of fundamental human needs and of the prevention of socio-economic pathologies. It is stressed in the paper that the...

We investigate the role discretionary (non-working) time plays in sustaining the gap between individuals’ concern about climate change and their propensity to act on this concern by adopting sustainable consumption practices. Using recent Australian survey data on climate change adaptation, we...

Although there is still no consensus on the causes of large differences in income per capita across countries, a growing literature considers culturally-based beliefs and institutions as main drivers of the latter differences (Guiso et al. 2006; Tabellini 2010). The intuition is that institutions...
