How does learning affect market liquidity? A simulation analysis of a double-auction financial market with portfolio traders
2007
We study the relationship between liquidity and prices in an artificial financial market where portfolio traders with limited resources interact through a continuous, electronic open book. We depart from the standard asset pricing framework in two ways. First, we assume that investors have incomplete information about the distribution of returns. Second, we model the portfolio choice problem using prospect-type preferences. We model the utility function in terms of deviations of the portfolio growth rate from a specified target growth rate, and we assume that investors are more sensitive to downside movements. We show that the parameters defining the learning process affect the price dynami…
GDP clustering: A reappraisal
2012
Abstract This note explores clustering in cross country GDP per capita using recently developed model based clustering methods for panel data. Previous research characterizing the components of the overall distribution of output either use ad hoc methods, or methods which ignore/subvert the panel nature of the data. These new methods allow the characterization of the possible autoregressive relationship of output between time points. We show that traditional static clustering decade by decade gives mixed results regarding clustering over time, while the application of longitudinal mixtures presents three distinct clusters at all periods of time.
Determinants of sub-central European government debt
2017
Abstract The aim of this paper is to analyze the determinants of sub-central government debt in Europe (Italy, France, Austria, Germany, Belgium and Spain) through estimation for each State based on corresponding panel data from 1996 to 2010. Furthermore, we estimate the debt model using a joint sample, consolidating conclusions on the most influential variables in terms of public debt. A comparative analysis of institutional frameworks in Europe shows that relationships between central and sub-central tax authorities have common traits, although the extent of change in each country remains unknown. In sum, this study shows that sub-sovereign government budgets are counter-cyclical, that ec…
International database on human capital quality
2007
In this research work, we have used a methodology which enables us to obtain qualitative indicators of human capital (QIHC) for 105 countries. This methodology relies on the potential to reconsider survey results comparatively by analysing the results of countries which took part in at least two different surveys. This allowed us to build indicators of comparable data concerning the quality of human capital in numerous countries and between 1964-2005: our results represent a valuable comparison to what has been done so far.
IN SEARCH OF BLACK ENTREPRENEURSHIP: WHY IS THERE A LACK OF ENTREPRENEURIAL ACTIVITY AMONG THE BLACK POPULATION IN SOUTH AFRICA?
2012
Compared to other ethnic groups, the black population of South Africa has a low participation rate in entrepreneurship activities. The research question of this article is to explain this empirical fact. Based on twenty-four expert interviews, five patterns of explanation are presented and elaborated: a historical apartheid explanation, a financial resources explanation, a human capital explanation, a traits and mindset explanation and a social capital and network explanation. The historical apartheid explanation cannot be qualified independently of the other explanations as a distinctive explanation of its own. Although missing financial resources and shortages of human capital are the fa…
Entrepreneurship, innovation and regional performance: application for the Spanish regions
2016
AbstractThe aim of this study is to test the importance of entrepreneurship or new business formation for explaining differences in economic performance in the Spanish regions, together with the role played by the endowments of innovation capital and the socio-economic capabilities of every region. The results show that the effect of new business formation on economic performance varies considerably between regions, and the type of start-up is highly important for the results obtained: entrepreneur endowments of high technology intensive sectors and medium technology intensive sectors, but not those of low technology intensive sectors, have a positive effect on regional performance. Also, t…
Entrepreneurship insolvency risk management: a case of Latvia
2011
Financial crisis and its consequences are visible in the capital adequacy of many commercial banks, which indicates that the approach banks took to assess credit risk was not sufficiently sophisticated. This article discusses practical methods of insolvency risk modelling for enterprises. In this paper, the authors analysed the accuracy of ten models developed by foreign authors to assess insolvency risk, which were validated on the database of Latvian companies. The authors have shown that models developed on historical data for foreign companies are less accurate than the model developed on the basis of financial indicators of Latvian companies. The authors developed a three-factor model …
The impact of corporate characteristics on the financial decisions of companies: Evidence on funding decisions by Italian SMEs
2015
Small and medium enterprises (SMEs) represent a large percentage of the corporate tissue of developed countries, but they do not have adequate attention. In fact, various researchers have focused their studies on larger and well-known companies. This paper aims to investigate the impact of corporate characteristic on the financial choices of SMEs, with a specific focus on agro-food micro companies. Access to finance is vital in business start-up, development and growth for SMEs, all with very different needs and facing different challenges in terms of finance compared to large companies. The lack of equity invested in small enterprises makes them more dependent on other external sources (e.…
The role of private equity: from focus on the product to focus on value creation
2009
Orginal article published by InderScience publishers. Avaialble from: http://dx.doi.org/10.1504/IJEIM.2009.025141 As a consequence of the paradigm shift from an industrial society to an information society, the role of the entrepreneur ought to change from being an inventor of product/services to become a value creator. Hence, the focus of entrepreneurial ventures should be shifting towards creating viable business models rather than superior product/services. One major implication of the shift of entrepreneurial endeavour from product/services towards creating new business models is that hands on investors behind companies’ have to be involved closer to the inception of new ventures in ord…
On the mechanics of progress in primary education
2003
03045; International audience; As countries grow rich, education improves in many ways. The sector enjoys more resources for education per primary school-aged child, not because of bigger budget allocations, nor an easing of the demographic burden on the system, but because the cost of inputs, especially teacher salaries, decline substantially relative to the per capita GNP. The extra resources enable countries to expand coverage and reduce the pupil–teacher ratio, with the latter receiving increasing emphasis during the past 20 years. The implicit trade-off against coverage raises questions about the efficiency and equity of education policies in developing countries, particularly in setti…
