Noncentral bimatrix variate generalised beta distributions

In this paper, we determine the density functions of nonsymmetrised doubly noncentral matrix variate beta type I and II distributions. The nonsymmetrised density functions of doubly noncentral and noncentral bimatrix variate generalised beta type I and II distributions are also obtained.     

An empirical approach to the organisational determinants of spin-off creation in European universities

Given the importance in recent years of the phenomenon of academic entrepreneurship in European universities, knowledge about determinants and performance of this technology transfer mechanism may have important managerial and policy implications. Applying the resource-based view at universities, we have tested the influence of five bundles of resources and capabilities on spin-off activity rates as well as on the performance of new spin-offs in a sample of seven European universities. These five bundles are: technology transfer policies and strategies; human capital; stock of technology; resources and capabilities of technology transfer offices; and support measures for academic entrepreneurship. Our results show that excellence of human capital and the presence of university-based financial support measures are strongly associated with both spin-off activity and performance. Another interesting finding is related to the availability of university-based non-economic support measures (training, counselling, etc.), which have no influence on spin-off activity but are significantly associated with performance of new spin-offs. We also discuss some interesting relationships between explanatory variables.     

Endogenous economic freedom and the wealth of nations: evidence from a panel of countries, 1996–2011

Indexes of economic freedom measure the degree to which the policies and institutions of countries are supportive of economic freedom. The authors find a considerable scope for improvement in Index of Economic Freedom, created by Heritage Foundation, since not all components of index have equal effect on economic well-being. Contrary to Heritage methodology the authors tackle the aggregation bias and highlight that each index component contributes differently to the level of economic freedom and subsequently to the level of income per capita. The level of fiscal freedom and monetary freedom exert the strongest influence on the overall index of economic freedom. Authors present the new endogenous cross-country ranking of 135 countries from Instrumental Variable-Two Stage Least Squares (IV-2SLS) empirical specification which removes the inconsistencies arising from the arbitrary assumption of the equivalent effect of each component on the overall index and, hence, the level of real income per capita.     

Misallocation and financial market frictions: Some direct evidence from the dispersion in borrowing costs

Financial frictions distort the allocation of resources among productive units—all else equal, firms whose financing choices are affected by such frictions face higher borrowing costs than firms with ready access to capital markets. As a result, input choices may differ systematically across firms in ways that are unrelated to their productive efficiency. We propose an accounting framework that allows us to assess empirically the magnitude of the loss in aggregate resources due to such misallocation. To a second-order approximation, the framework requires only information on the dispersion in borrowing costs across firms, which we measure—for a subset of U.S. manufacturing firms—directly from the interest rate spreads on their outstanding publicly-traded debt. Given the observed dispersion in borrowing costs, our approximation method implies a relatively modest loss in efficiency due to resource misallocation—on the order of 1 to 2 percent of measured total factor productivity (TFP). In our framework, the correlation between firm size and borrowing costs has no bearing on TFP losses under the assumption that financial distortions and firm-level efficiency are jointly log-normally distributed. To take into account the effect of covariation between firm size and borrowing costs, we consider a more general framework, which dispenses with the assumption of log-normality and which implies somewhat higher estimates of the resource losses—about 3.5 percent of measured TFP. Counterfactual experiments indicate that dispersion in borrowing costs must be an order of magnitude higher than that observed in the U.S. financial data, in order for misallocation—arising from financial distortions—to account for a significant fraction of measured TFP differentials across countries.     

Gender Inequality in the Spanish Public Pension System

This contribution studies revenue sharing in the public pension system in Spain from a gender perspective, revealing that differences are evident in the percentage of men and women entitled to different types of pensions and in the average fiscal amount per pension for men and women. Using 2010 data, the study analyzes how labor market conditions are reflected in pension type and amount for women pensioners, yielding two important conclusions: the income of women pensioners decreases, relative to men, with age; and the degree of inequality of pensions among women is lower than that among men. These gender differences owe to the contributory character of the system, which reproduces the labor market inequalities of both genders – inequalities that ultimately derive from the social division of roles in which women remain responsible for unpaid care work. This conclusion is consistent with similar studies on other European countries and world regions.     

Region,Regionness and Regionalism in Latin America: Towards a New Synthesis

Latin American regional governance today represents a conglomerate of commercial, political and trans-societal welfarist integration projects. In this overlapping and sometimes conflicting scenario what Latin Americanness should mean, and how integration projects should respond to current challenges of global political economy are being redefined. The focus of the paper is twofold: to better understand current regional transformations and to discuss what new developments mean for how we theorise non-European regionalism. Looking at the Bolivarian Alliance for the Americas and the Union of South American Nations we ask: How are we to understand regional agreements that are grounded in different systems of rules, alternative ideas and motivations that contest ‘open regionalism’? We argue that Union of South American Nations (UNASUR) and Bolivarian Alliance for the Americas (ALBA) represent different pathways to regional building, creating foundations for post-hegemonic and post-trade regional governance. We thus challenge New Regionalist approaches that assume regionalism as taking place within and modelled by neoliberal economics, establishing the debate around ‘old’ vs. ‘new’ regionalism. As these categories are limited in grasping the full meaning and implications of post-hegemonic regional orders, we discuss UNASUR and ALBA as ‘arenas for action’ to understand divergent practices, outcomes and types of regionness emerging in alternative regional spaces in South America.     

THE REVOLUTION WITHIN: ICT AND THE SHIFTING KNOWLEDGE BASE OF THE WORLD'S LARGEST COMPANIES

This empirical article analyses the importance of information and communications technologies (ICT) in the technological diversification trend among the world's largest manufacturing firms during the 1980s and 1990s. The objective of the research is twofold: first, to emphasise the emerging differences among technologies when companies from different industries patent outside their traditional technological capabilities; secondly, to investigate whether the tendency among large companies from all industries to patent in ICT is distinctive when compared with the tendency to patent in other technologies. We find that technological diversification in large companies has clearly occurred in ICTs. Non-ICT specialist industries increasingly develop, rather than just utilise, the cluster of ICT-related technologies. We conclude that the development of corporate capabilities in the key technologies of the emerging ICT paradigm is more widespread than previously emphasised in the literature. One implication of this observation is that technological diversification and the information revolution may be related phenomena.     

Does CEO gender matter for bank risk?

This paper addresses the relation between CEO gender and bank risk. We exploit a unique dataset of 365 Polish cooperative banks, 42% of which are run by female CEOs. We find that banks headed by female CEOs are less risky: they report higher capital adequacy and equity to assets ratios. Credit risk in female-led banks is not different from male-led banks, and therefore higher capital adequacy does not stem from lower asset quality and is likely to be linked to higher risk aversion of female CEOs. Our evidence supports the view that women are more risk averse bank CEOs than men. Our findings suggest that gender quotas in bank boards can contribute to reduce risk-taking behavior.
