Wage and employment decisions of enterprises in downsized industries:deliverable No. 11 to 13

The 5th framework programme research project ACCESSLAB researches the capability of candidate countries’ regions to deal with asymmetric shocks. Its goal is to provide analysts and policy makers with research results relevant to the process of enlargement. The project takes a broad and comparative view of labour market adjustments to address these issues. It examines the topic from both a macroeconomic and microeconomic viewpoint. It considers different adjustment mechanisms in depth and compares results with the European Union. It draws on a) the experiences in transition countries in the last decade, b) the experience of German integration and c) the experiences of border regions to gain insights on the likely regional labour market effects of accession of the candidate countries.

Managing the dynamic configuration of enterprises

Due to environmental changes and business trends such as globalisation, outsourcing and virtualisation, more and more companies get involved in business activities that are outside their direct control. This typically occurs by entering into collaborative relationships and joint ventures with specialised companies in order to fulfil the demands of customers quickly (DiMaggio, 2001). Organisational structures that results from such collaborative relationships and joint ventures are referred to in this paper as enterprises and the management of them known as enterprise management. The authors use the definition of the European Commission (2003) that defines an enterprise as “… an entity, regardless of its legal form … including partnerships or associations regularly engaged in economic activities.” Therefore in its most simple form an enterprise could be a single integrated company. However, findings from this research show that enterprises can also be made up of parts of different companies and the structure of the enterprise is contingent upon a variety of different factors. The success of the enterprise as a collaborative venture depends on the ability of companies to intermediate their internal core competencies into other participating companies’ value streams and simultaneously outsource their own peripheral activities to companies that can perform them quicker, cheaper, and more effectively (Lal et al., 1995). In other words, the peripheral activities of one member-company must be complemented by a core competence of another member-company within an overall enterprise.

Igazolható-e az üzleti ciklus az iparágak viselkedésével? = Can business cycles be proved with the behavior of enterprises?

A dolgozat alapja egy olyan Leontief-típusú gazdaság, ahol minden egyes ágazatban egy vállalat termel, tehát monopóliumokból áll a gazdaság. A vállalatok termelnek, és a termékeiket a piacon értékesítik. A gazdaság mozgásegyenleteit a vállalati mérleg összefüggések, valamint a piaci csere után a gazdaságban, a termékek készletváltozása írja le. Az így létrejött mozgásegyenletekből arra következtethetünk, hogy a ciklusok egy ilyen modellben szükségszerűen kialakulnak, tehát az üzleti ciklus a gazdaság működéséhez hozzátartozik. Journal of Economic Literature (JEL) kód: D46, E32. = The aim of the paper is to analyze a Leontief-type economy, i.e. all firms produce only one product and only one technology. The firms sell the products on a monopolistic market. The move of this economy is controlled by the balance sheet expressions and the inventory level fluctuations. The differential equations of the move of this economy show a cyclical movement of the economy along the balanced growth path. Journal of Economic Literature (JEL) kód: D46, E32.

What lessons can we learn from the present economic crisis for the possible future strategies of enterprises - lesson from Hungary and Slovakia

The paper explores the characteristics of the present economic crisis at enterprise level and its comsequences for possible growth after the crisis. The study builds on international experiences concerning recovery from crisis during the previous economic downturns between 1980 and 2002. Survey results in Hungary and Slovakia are presented with special attention to how companies tried to react to the present economic recession. The study analyses the possible consequences of the strategies followed by the Slovakian and Hungarian firms during the crisis period from the point of view of capabilities for utilizing the options for growth when demand will start to increase.

Deciphering complex patterns of class-I HLA-peptide cross-reactivity via hierarchical grouping

T-cell responses in humans are initiated by the binding of a peptide antigen to a human leukocyte antigen (HLA) molecule. The peptide-HLA complex then recruits an appropriate T cell, leading to cell-mediated immunity. More than 2000 HLA class-I alleles are known in humans, and they vary only in their peptide-binding grooves. The polymorphism they exhibit enables them to bind a wide range of peptide antigens from diverse sources. HLA molecules and peptides present a complex molecular recognition pattern, as many peptides bind to a given allele and a given peptide can be recognized by many alleles. A powerful grouping scheme that not only provides an insightful classification, but is also capable of dissecting the physicochemical basis of recognition specificity is necessary to address this complexity. We present a hierarchical classification of 2010 class-I alleles by using a systematic divisive clustering method. All-pair distances of alleles were obtained by comparing binding pockets in the structural models. By varying the similarity thresholds, a multilevel classification was obtained, with 7 supergroups, each further subclassifying to yield 72 groups. An independent clustering performed based only on similarities in their epitope pools correlated highly with pocket-based clustering. Physicochemical feature combinations that best explain the basis of clustering are identified. Mutual information calculated for the set of peptide ligands enables identification of binding site residues contributing to peptide specificity. The grouping of HLA molecules achieved here will be useful for rational vaccine design, understanding disease susceptibilities and predicting risk of organ transplants.

Financial analysis of small-scale fish farming enterprises to alleviate poverty in homestead

This paper focuses on the financial analysis involved in setting up of fish farming on a small-scale in a homestead. About 0.5 acres of land was used for the construction of pond which as a stock of Clarias spp/ Heterobranchus spp and Tilapia spp at the ratio of one to three for a period of 12 months. The land/land development cost is N26,500.00, pond construction cost, N35,700.00, equipment cost, N2,650.00 and stock/Input requirement cost N155,727.00 while the revenue from sales is N376,000.00. A cash flow analysis is also calculated for the fish farm, which is N155,423.00 for first year cash flow, and appropriate profit/mosses were calculated for five-year production cycle of N1,036,515.00 million. At the end appreciable profit is realized from the enterprises. This type of enterprises is viable for small-scale farmers to practices and adopted for financial support for their family

Spiking Dynamics during Perceptual Grouping in the Laminar Circuits of Visual Cortex

Grouping of collinear boundary contours is a fundamental process during visual perception. Illusory contour completion vividly illustrates how stable perceptual boundaries interpolate between pairs of contour inducers, but do not extrapolate from a single inducer. Neural models have simulated how perceptual grouping occurs in laminar visual cortical circuits. These models predicted the existence of grouping cells that obey a bipole property whereby grouping can occur inwardly between pairs or greater numbers of similarly oriented and co-axial inducers, but not outwardly from individual inducers. These models have not, however, incorporated spiking dynamics. Perceptual grouping is a challenge for spiking cells because its properties of collinear facilitation and analog sensitivity to inducer configurations occur despite irregularities in spike timing across all the interacting cells. Other models have demonstrated spiking dynamics in laminar neocortical circuits, but not how perceptual grouping occurs. The current model begins to unify these two modeling streams by implementing a laminar cortical network of spiking cells whose intracellular temporal dynamics interact with recurrent intercellular spiking interactions to quantitatively simulate data from neurophysiological experiments about perceptual grouping, the structure of non-classical visual receptive fields, and gamma oscillations.

The role of local grouping and global orientation contrast in perception of orientation-modulated textures

We explored the contribution to perception of orientation-modulated textures of visual processes selective either for orientation contrast or orientation grouping. To distinguish between these two processes we manipulated the axis of local grouping of texture elements independently of the direction of global orientation modulation. The general question posed was whether visibility of texture structure (measured as threshold for discriminating spatial-frequency of texture structure) is dependent on the magnitude of orientation contrast, strength and direction of local grouping, or some combination of the two. We demonstrated that the factor of primary importance is the amplitude of global orientation contrast rather than the presence of local grouping content. Using orientation-interleaved textures (containing two superimposed textures modulated around orthogonal orientations), we further showed that orientation single-opponent processes are a more likely candidate for detecting orientation contrast than double-opponent processes.

Birth, Survival and Growth of Small and Medium Sized Enterprises in Poland: 1990-1994

This research is based on a unique and extensive database which tracks the employment, payroll and sales of individual Polish firms for the period 1990 to 1995. This allowed the authors to calculate the birth, survival and growth rates for different categories of enterprises (state-owned, cooperative, private, foreign-owned and privatised after 1990) and regions. These data match data collected in the United States, making it possible to compare the Polish situation with that of the state of Michigan. Analysis of the data and lessons from the Poland-Michigan comparisons provide a solid basis for the formulation of new policy recommendations for Poland. Allowing for certain important differences, Poland would still seem to need a higher rate of births of new companies. New small private companies and companies with foreign capital can be seen as the main source of job creation and economic revitalisation. To strengthen positive trends in the economy, Poland should create a model of institutional support for both potential entrepreneurs and foreign investors.

The Effects of Privatization of State-Owned Enterprises in Poland and East Germany

The main goal of this project was to propose appropriate methods of analysing the effects of the privatisation of state-owned enterprises, methods which were then tested on a limited sample of 16 Polish and 8 German enterprises privatised in 1992. A considerable amount of information was collected relating to the six-year period 1989-1994 relating to most aspects of the companies' activities. The effects of privatisation were taken to be those changes within the enterprises which were the result of privatisation, in such areas as production, the productivity of labour and fixed assets, investments and innovations, employment and wages, economic incentives (especially for top managers), financing (internal and external sources), bad debts and economic effects (financial analysis). A second important goal was to identify the main factors which represent methodological obstacles in surveys of the effects of privatisation during a period of fundamental transformation of the entire economic system. The list of enterprises for the research was compiled in such a way as to allow for the differentiation of ownership structures of privatised firms and to permit (at least to a certain extent) the empirical verification of some hypotheses regarding the privatisation process. The enterprises selected were divided into the following three groups representing (as far as possible) various types of ownership structures or types of control: (1) enterprises control by strategic investors (domestic or foreign), (2) enterprises controlled by employees (employee-owned companies), (3) enterprises controlled by managers. Formal methods such as econometric models with varying parameters were used to separate pure privatisation effects from other factors which influence various aspects of an enterprise's working, including policies on the productivity of labour and capital, average wages, the remuneration of top managers, etc. While the group admits that their findings and conclusions cannot be treated as representative of all privatised enterprises in Poland and Germany, they found considerable convergence with their findings and those of other surveys conducted on a wider scale. The main hypotheses that were confirmed included that privatisation (especially in companies controlled by large investors and managers) leads to a significant increase in the effectiveness of these production process, growing pay differentials between different employee groups (e.g. between executives and rank-and-file employees) and between different jobs and positions within particular professional groups. They also confirmed the growing importance in incentives to top executives of incentives linked with the company's economic effects (particularly profit-related incentives), long-term incentives and the capital market.
