The Small Business Capital Market Behavior in Athens Stock Exchange

Financing small and medium enterprises (SMEs), especially business investments and growth, is a composite and particular complicated affair in the Greek entrepreneurial reality. This paper examines the significance of secondary capital markets, as an alternative source of financing small-medium enterprises’ new entrepreneurial plans. Cointegration technique is applied to test the relationship between the secondary capital market and the dominant sectors in Athens Stock Exchange (ASE). Causality tests are also used to provide evidence on the existence of interdependence between the cointegrated series. The results indicate that there is significant uni-directional causality between primary and secondary capital market in Greece, enhancing us to suggest valuable policy implications.      

“I don’t think Turkish used here is normal”: language attitudes of Turkish university students towards Cypriot Turkish

As a significant factor in social relationships, language attitudes of students are important to explore when building a school culture of tolerance. This study examines the language attitudes of university students from Turkey towards Cypriot Turkish (CT) and Standard Turkish. A mixed methods approach was adopted where 94 Turkish university students studying in the northern part of Cyprus where the two varieties are spoken, responded to a questionnaire in the first phase. The results of the analysis of this survey showed that the participants had somewhat negative attitudes towards CT. In the second phase of the study, where three focus groups were conducted, the findings of the first phase were confirmed. Intertwined with discourses of class, the participants specifically referred to “correctness” and “intelligibility” as important issues for their evaluations of CT and its speakers. CT was also perceived as an important marker of Turkish Cypriotness by the participants and was projected to be lower than any other variety of Turkish spoken in Turkey.

     

Objective methods for graphical structural learning

Graphical models are used for expressing conditional independence relationships among variables by the means of graphs, whose structure is typically unknown and must be inferred by the data at hand. We propose a theoretically sound Objective Bayes procedure for graphical model selection. Our method is based on the Expected-Posterior Prior and on the Power-Expected-Posterior Prior. We use as input of the proposed methodology a default improper prior and suggest computationally efficient approximations of Bayes factors and posterior odds. In a variety of simulated scenarios with varying number of nodes and sample sizes, we show that our method is highly competitive with, or better than, current benchmarks. We also discuss an application to protein-signaling data, which wieldy confirms existing results in the scientific literature.     

Wage mobility in Europe. A comparative analysis using restricted multinomial logit regression

The paper investigates cross-country differences in wage mobility in Europe using the European Community Household Panel. We examine the impact of specific wage-setting institutions, such as the collective bargaining and the trade union density, the employment protection regulation and the welfare state regime on wage mobility. We apply a log-linear approach that is very much similar to a restricted multinomial logit model and much more flexible than the standard probit approach that is typically applied in the research on wage mobility. It is shown that the macro-economic context and the aforementioned specific institutions explain a substantial part of the cross-country variation that is larger than the part that regime type explains. The findings also confirm the existence of an inverse U-shape pattern of wage mobility, showing a great deal of low-wage and high-wage persistence in all countries.     

Research needs for assessing online value creation in complex consumer purchase process behavior

Consumers face considerable frustration when purchasing structurally and/or semantically complex high-involvement products online. Reliance on computer-mediated communications for their information needs may result in functional and emotional frustration from information overload and lack of personal trust. This paper proposes a responsive real-time information system as a proxy for a perceptive sales representative who assesses customer needs based on information exchanges and then offers appropriate responses. By tracking and analyzing a consumer's online activity, vendors can offer information relevant to the consumer's real-time needs, facilitating their purchase process. In essence, this is a real-time value co-creation process based on the consumer offering cues to vendors through their key strokes and mouse click activity. This allows for differentiated information offerings for inexperienced and more experienced consumers, creating value by dynamic information serving. Where appropriate value is created, consumers will experience less frustration and continue online, rather than possibly moving offline or to alternative vendors. In examining the bases of consumer information needs in complex purchases, this paper identifies the data required to enable a responsive dialog between vendors and consumers.     

Sensitivity of consumption to income and to government purchases: some specification and estimation issues

The paper derives a nonlinear error-correction model (ECM) for consumption and shows that existing models that are based on quadratic utility, combine permanent income and current-income consumption, and nest (or could nest) the hypothesis of substitutability between private consumption and government purchases are special cases of the ECM. The importance of some econometric issues that have not received proper attention in the literature is demonstrated by estimating the models using US aggregate quarterly data, 1953:1-1992:4. The evidence suggests that the ECM produces more reliable estimates than do the existing restrictive models.     

New market socialism: a case for rejuvenation or inspired alchemy?

The aim of this paper is to examine the relative merits anddrawbacks of two recent models of market socialism proposedby Bardhan and Roemer. This is done, first, by putting thesemodels into the perspective of the history of economic thought.Thus, after presenting the basic elements of the early Langemodel as well as the Austrian and ‘new information economics’critiques, the necessary comparisons and contrasts are madeto see what new light these new models bring into this debate.In addition, the internal consistency and coherence of thesemodels is checked in terms of their own proclaimed goals. Last,a more radical methodological critique is provided.
