Policy Target

This paper provides a first attempt in analyzing the role of Polish economy in the production structure of the global economy in the early years of the 21st century. For the purpose of this analysis, we propose a new approach in which two most important aspects of interindustry linkages in a global input-output model are examined. Contrary to previous studies focused on output-oriented key sector analyses in post-communist CEE economies, we focus on a fundamental policy target variable — income per gross output. In order to analyze the issues in question in a dynamic framework, the empirical results are based on the 2000 and 2014 global intercountry input-output tables for the 28 EU countries as well as 15 other major countries in the world.

Relationship Of

Dopaminergic modulation of prefrontal cortical activity is known to affect cognitive functions like working memory. Little consensus on the role of dopamine modulation has been achieved, however, in part because quantities directly relating to the neuronal substrate of working memory are difficult to measure. Here we show that dopamine increases the gain of the frequency-current relationship of layer 5 pyramidal neurons in vitro in response to noisy input currents. The gain increase could be attributed to a reduction of the slow afterhyperpolarization by dopamine. Dopamine also increases neuronal excitability by shifting the input-output functions to lower inputs. The modulation of these response properties is mainly mediated by D1 receptors. Integrate-and-fire neurons were fitted to the experimentally recorded input-output functions and recurrently connected in a model network. The gain increase induced by dopamine application facilitated and stabilized persistent activity in this network. The results support the hypothesis that catecholamines increase the neuronal gain and suggest that dopamine improves working memory via gain modulation.

The subject of this research are small and medium enterprises (SME) in the Polish economy, the support of this sector by local government and the functioning of small and medium enterprises in the local system of the town and commune of Pułtusk. The aim of this study is to present the condition and the role of SME in the local systems in light of the selected features of this sector in the country and evaluation of support for SME given by local government of the town and the commune. The case study research methods applied were literature research, documentation review and survey-based research using questionnaire. The survey was conducted in spring, 2014, on a random sample. The research resulted in learning the profile of a local entrepreneurs and the action characteristics of SME in the examined unit. The diagnosis of the sector’s situation was made, the stimulating and limiting factors of its prosperity were identified. The SME support system of local government and the entrepreneurs’ expectations towards commune government in the field of development of local enterprises were evaluated. The results and conclusions confirm the need for development of local government activity in formulating and implementation of the development of local enterprises policy.

Current Concerns

According to the current concerns about social welfare and environmental protection, integrated in a model assimilated to intrabusiness relations, our research started from the analysis of the initial model SAM, which will be transformed in order to develop the SAMI model under six research objectives. The need of improving SAM matrix started to connect it directly to the regional economic systems and continued to a new approach on Input-Output Analysis. Nowadays, SAM describes the intraregional connections between regional economic actors using the role of different income categories. Moreover, SAM can quantify different regional multipliers. All deficiencies previously identified in connection to SAM model have been reviewed and resolved within the proposed SAMI model by the authors of this paper. The purpose of this research is the launch of an absolutely new mathematical model (SAMI) and its practical testing at regional level. This model is able to systematize the links between the local and regional businesses, under the matrix (SAMI) flow, for all kinds of companies and to assist the regional decision, as well. Czamanski was not able to escape from the input-output prison’s approach. This is why he continued to use the linear interdependencies between the industries, economic sectors and economic actors. The income is able only to approximate the individuals and other economic actors’ welfare. If the increase in the average and aggregate income is doubled by an unfair distribution of income in two countries which have the same average income, the effects on welfare vary a lot. A relatively similar effect comes from the government policy differences in income distribution and redistribution.

The Empirical Analysis

The paper refers to the construction of some Indexes of Competitiveness and their application to the empirical analysis of the behaviour of Italian manufacturing industry in recent years. The idea is that an essential role in competitiveness is played by the specific characteristics of the goods and services concerned. With particular reference to competition between a mature economy (like Italy) and an emergent one (e.g. like China), attention is specifically directed to the behaviour of goods' demand and supply according to their characteristics. Then, an extended Leontief Input-Output model is pursued including the impact of goods' characteristics. At the empirical level, the role of goods' characteristics is analysed as to the behaviour of competitiveness of Italian manufacturing products in the period from 2000 to 2008.
