Abstract

The paper is an attempt at reviewing the classical theory of externalities and club goods in the new context of flow economy and network relations, as well as the role of human capital connected with high quality surroundings (urban environment), which is a catalysing factor, and allows the formation of new resources and new competitive advantages for cities and busiensses.

Abstract

The need for a dwelling is one of the basic needs of every human being. The housing policy, which belongs to one of the pillars of the social policy of the state, is responsible for satisfying this need. It is carried both at the central and local level. The report aims to show the evolution of this policy in Poland from 1989, when the burden of providing housing to the society was largely shifted to the private sector, to the present times, when the state is starting to take action to solve the problem of housing shortages for the less prosperous part of society. First, housing resources are characterized in terms of their ownership and function. Then, the housing policy, its objectives and instruments are described in theoretical terms. The competences of communes in the fi eld of housing economy are characterised in further part. The diagnosis of housing condition in Poland is presented in the regional context and compared to other countries. The last parts of the report deal with the assessment of housing policy in Poland after 1989 on the national and local level. Based on this assessment, recommendations have been made regarding the directions of activities at the local and supra-local level in the area of improving the condition of housing in Poland. Special emphasis in recommendations is placed on the need for an integrated approach to the implementation of housing policy.

Abstract

In this paper we develop an open-economy endogenous growth model to examine the influence of fiscal policy on the economy in the long run. We allow for public deficit and 5 types of taxes. One of the novel features is separate treatment of interest rates on public and private debt, both of which are linear functions of appropriate debt-to-GDP ratios. Two extreme situations are analyzed: a model of “decentralized economy”, where economic agents do not take into account any externalities, and a model of “benevolent social planner”. We derive the rules of optimal fiscal policy that induce economic agents to internalize all externalities. Theoretical results are illustrated with an empirical analysis for Poland. The optimal values of several fiscal policy instruments for Poland are calculated.

Abstract

Clusters belong to the regional innovation system, which led to the formulation and implementation of the cluster-based policy in many countries. The positive impact of clusters on the competitiveness of regions was confirmed by empirical studies. Absence of clusters means retardation in a regional development. The implementation of cluster policy supporting coopetition into the scope of principled regional policy assumptions seems urgent. In this way effective conditions for the formation of growth poles around industries specific for a given region will be developed and, consequently, the economic specialization of individual regions will be achieved. Observation of the benefits resulting from the functioning of clusters in the region, taking into account their possible negative impact, will allow to determine the specificity of regional development policy based on clusters. These problems indicated above are the subject of this study, based on the Polish and foreign literature available on the subject employing the desk research method.

Abstract

Internalization of external economic effects on urban sprawl affected areas. An example of the Krakow Metropolitan Area, The study is a discussion on economic externalities, with particular emphasis on technological effects. Attention is also paid to the problem of internalization of economic external effects caused by movement (transport) in areas affected by the urban sprawl process. The research was conducted for all communes of the Krakow Metropolitan Area (KOM), as a result of which the value of: directly incurred financial losses and the value of lost time generated by the necessity of commuting and return in the space of KOM were presented.

Abstract

The aim of this paper is to consider the not so well investigated problem of the role that language has played in Karl Marx’s thinking. The first section discusses several examples of Marxist attempts at philosophical or linguistic reflection on language. I propose the thesis that Marxist meaning theory did not seriously evolve due to the domination of the ‛Traditional Meaning Theory’ (TMT) – irrespective of the actual social conditions. In the second section I undertake some adumbrations on the tendencies of contemporary philosophy of language, such as externalism or pragmatism, whose premonitions can be found in Marx. I also point out that combined with historical materialism they can no longer fit TMT. Finally, I argue that the notion of language and the division of linguistic labor may solve some issues of Marx’s conception of ideology.

Abstract

This paper presents a robust control technique for small-scale unmanned helicopters to track predefined trajectories (velocities and heading) in the presence of bounded external disturbances. The controller design is based on the linearized state-space model of the helicopter. The multivariable dynamics of the helicopter is divided into two subsystems, longitudinallateral and heading-heave dynamics respectively. There is no strong coupling between these two subsystems and independent controllers are designed for each subsystem. The external disturbances and model mismatch in the longitudinal-lateral subsystem are present in all (matched and mismatched) channels. This model mismatch and external disturbances are estimated as lumped disturbances using extended disturbance observer and an extended disturbance observer based sliding mode controller is designed for it to counter the effect of these disturbances. In the case of heading-heave subsystem, external disturbances and model mismatch only occur in matched channels so a second order sliding mode controller is designed for it as it is insensitive to matched uncertainties. The control performance is successfully tested in Simulink.
