Innovation of IT metasystems by means of event-driven paradigm using QDMS

Globalisation of world economy brings new and more complex demands to business systems. In order to respond to these trends, business systems apply new paradigms that are inevitable reflecting on management metasystems – quality assurance (QA), as well as on information technology (IT) metasystems. Small and medium enterprises (in particular in food industry) do not have possibilities to access external resources to the extent that could provide adequate keeping up with these trends. That raises the question how to enhance synergetic effect of interaction between existing QA and IT metasystems in order to overcome resource gap and achieve set goals by internal resources. The focus of this article is to propose a methodology for utilisation of potential of quality assurance document management system (QDMS) as prototypical platform for initiating, developing, testing and improving new functionalities that are required by IT as support for buiness system management. In that way QDMS plays a role of catalyst that not only accelerates but could also enhance selectivity of the reactions of QA and IT metasystems and direct them on finding new functionalities based on event-driven paradigm. The article tries to show the process of modelling, development and implementation of a possible approach to this problem through conceptual survey and practical solution in the food industry.     

Long-term dynamics of the VIX index and its tradable counterpart VXX

We study the relationship of the VIX index and the exchange-traded note VXX on various timescales. We find that changes of VIX and VXX are correlated only contemporaneously on timescales of days, but VIX leads VXX on timescales of months. Next, we construct a simple joint model for VXX and VIX which replicates all the key characteristics of these two time series, but in which VIX and VXX are related only via a correlated error term. Therefore, VIX cannot be used as a predictor of VXX and there is no apparent trading profit opportunity.     

Does reducing unemployment insurance generosity reduce job match quality?

This paper analyzes how a change in Slovenia's unemployment insurance law affected the quality of jobs workers found after periods of unemployment. Taking advantage the “natural experiment” we show through difference-in-differences estimation results that reducing the potential duration of unemployment benefits had no detectable effect on wages, on the probability of securing a permanent rather than a temporary job, or on the duration of the post-unemployment job.     

Winners and Losers in Transition: Returns to Education, Experience, and Gender in Slovenia

This article, using an unusually rich data set on Slovenianworkers over the 1987–91 period, explores changes in thestructure of wages and employment produced by transition toa market economy. Employment and real wages fell dramaticallyover the period, but the losses were borne disproportionatelyby the least skilled. Across all sectors of the economy, relativewages and employment rose for the most-educated workers. Womengained in comparison with men, primarily because women occupiedsectors less adversely affected by the transition. Pension policies,which encouraged retirement, are shown to have drastically reducedemployment of experienced workers and helped contribute to risingreturns to skill. Increases in returns to education and experiencecontributed to rising wage inequality, but the variance of wagesincreased for workers with identical skills as well.     

Do Market Pressures Induce Economic Efficiency? The Case of Slovenian Manufacturing, 1994–2001

Using a unique longitudinal data set on all manufacturing firms in Slovenia from 1994 to 2001, this article analyzes how firm efficiency changed in response to changing competitive pressures associated with the transition to market. Results show that the period was one of atypically rapid growth of total factor productivity (TFP). The rise in firm efficiency occurs across almost all industries and firm types: large or small, state or private, domestic or foreign owned. Changes in firm ownership type have no direct impact on firm efficiency. However, increased market competition related to rising market share of private firms, new market entrants, foreign‐owned firms, and international trade raises TFP across all firms in an industry, whether private or state owned. In addition, competitive pressures that sort out inefficient firms of all types and retain the most efficient, coupled with the entry of new private firms that are at least as efficient as surviving firms, prove to be the major source of TFP gains. Results strongly confirm that market competition fosters efficiency.     

Sociology of economics or sociology of economy? theoretical-methodological arguments for sociological economics

This paper makes a proposal for reintroducing sociological or social economics into contemporary economic science. Such a reintroduction is proposed to be substantive, by analyzing the social structuring of the economy, and formal, by including sociological/social economics in the current (JEL) classification system of economic disciplines (code A.15). Both epistemological and ontological arguments can be presented to support the proposal. Epistemological arguments invoke the presence of essential components of sociological economics in the development of economic thought, and ontological arguments stress the role of social factors in economic life. In this paper I present primarily epistemological (theoretical-methodological) arguments for sociological economics, and secondarily ontological ones. I show that the present designation, sociology of economics, is something different from sociological or social economics in that the former refers to economic epistemology (knowledge) and the latter to economic ontology (reality). I conclude that, in addition to a sociology of economic science, we need a sociology of economic life. There is nothing surprising in the habit of economists to invade the sociological field. A major part of their work—practically the whole of what they have to say on institutions and on the…[social] forces which shape economic behavior—inevitably overlaps the sociologist’s preserves. In consequence, a no man’s land or everyman’s land has developed that might conveniently be called economic sociology … [or sociological economics] (Schumpeter 1956:134). The author is grateful to two anonymous referees for their constructive comments on an earlier version of this article.     

Zoos,Sanctuaries and Turfs: Enactments and Uses of Gay Spaces during the Holidays

Extant theory suggests that the existence of gay space is an important (or even critical) element of gay people's holidays. However, more knowledge on the roles that gay spaces play during the holidays is needed. Drawing on interviews with 53 gay tourists, this paper suggests that the roles gay spaces play differ across gay tourists. Some interviewees enact gay spaces as ‘sanctuaries’, at which one can feel free and openly show one's sexuality. Others feel that gay spaces resemble ‘zoos’, i.e. tourist attractions at which straights gaze upon gays. Finally, some tourists find that gay spaces are too male oriented or even men's turfs.

How the Subprime Crisis went global: Evidence from bank credit default swap spreads

How did the Subprime Crisis, a problem in a small corner of U.S. financial markets, affect the entire global banking system? To shed light on this question we use principal components analysis to identify common factors in the movement of banks' credit default swap spreads. We find that fortunes of international banks rise and fall together even in normal times along with short-term global economic prospects. But the importance of common factors rose steadily to exceptional levels from the outbreak of the Subprime Crisis to past the rescue of Bear Stearns, reflecting a diffuse sense that funding and credit risk was increasing. Following the failure of Lehman Brothers, the interdependencies briefly increased to a new high, before they fell back to the pre-Lehman elevated levels – but now they more clearly reflected heightened funding and counterparty risk. After Lehman's failure, the prospect of global recession became imminent, auguring the further deterioration of banks' loan portfolios. At this point the entire global financial system had become infected.     

Worker flows, job flows and firm wage policies

Like many transition economies, Slovenia is undergoing profound changes in the workings of the labour market with potentially greater flexibility in terms of both wage and employment adjustment. To investigate the impact of these changes, we use unique longitudinal matched employer‐employee data that permits measurement of employment transitions and wages for workers and enables links of the workers to the firms in which they are employed. We can thus measure worker flows and job flows in a comprehensive and integrated manner. We find a high pace of job flows in Slovenia especially for young, small, private and foreign‐owned firms and for young, less educated workers. While job flows have approached the rates observed in developed market economies, the excess of worker flows above job flows is lower than that observed in market economies. A key factor in the patterns of the worker and job flows is the determination of wages in Slovenia. A base wage schedule provides strict guidelines for minimum wages for different skill categories. However, firms are permitted to offer higher wages to an individual based upon the success of the worker and/or the firm. Our analysis shows that firms deviate from the base wage schedule significantly and that the idiosyncratic wage policies of firms are closely related to the observed pattern of worker and job flows at the firm. Firms with more flexible wages (measured as less compression of wages within the firm) have less employment instability and are also able to improve the match quality of their workers.

Advertising’s image —U.S. and Yugoslavia

Advertising is one of the institutions which cut across cultures, and this study assesses comparative differences and similarities between the U.S. and Yugoslavia in their attitudes toward advertising as an institution. The comparison is effected through replication in Yugoslavia of the Bauer-Geyser Study. The findings indicate that advertising in Yugoslavia is not a salient issue, although there is a greater homogeneity of salience of other specific issues than in the U.S. More U.S. respondents expressed a need for change in advertising; more Yugoslav respondents were indifferent toward advertising. The reasons for liking and disliking advertising also differed in the two samples. The implications are that the intensity of advertising in the U.S. has made it a salient irritant to at least a minority of consumers, whereas in Yugoslavia there is an immediate need for improvement in the creative aspect of advertising.
