Conceptualization and measurement of disability in studies on subjective well-being: a critical review and evidence from the Italian Health Surveys

The main aim of this study is to assess, through a wide literature review, whether the concept of “disability,” as variously formulated, can be considered a good foundation for scientific research on happiness and subjective well-being, as well as the effect of some conceptualizations on the understanding of the relationship between happiness and disability. The literature review includes longitudinal population studies, cross-sectional surveys and longitudinal clinical researches. The empirical part of the study, based on the 2013 Italian Health Interview Survey, shows some examples of the impact of different definitions of disability on the subjective well-being variability. The Italian Health Interview Survey is conducted every 5 years and carried out on a sample of about 60,000 households and 162,000 respondents distributed in 1456 municipalities. Some suggestions for future research, based on a vision of the multifaceted nature of disability, are proposed.     

Underpricing of venture backed IPOs: a meta-analysis approach

ABSTRACT

Listing firms are subject to underpricing mainly because of asymmetries of information, but IPOs backed by a venture capitalist are generally found to be subject to less underpricing. Although this condition is commonly verified by the empirical evidence, a consistent number of studies finds contrasting results. This paper aims to answer to the question: do venture capitalists effectively reduce underpricing at IPO? Evidence provides a negative answer, with venture-backed IPOs having higher underpricing especially in US markets. Meta-regression results confirm the different effect of VC between US and European IPOs. Results overall suggest that other explanations on underpricing might hold in US markets.     

Storable votes

Motivated by the need for more flexible decision-making mechanisms in the European Union, the paper proposes a simple but novel voting scheme for binary decisions taken by committees that meet regularly over time. At each meeting, committee members are allowed to store their vote for future use; the decision is then taken according to the majority of votes cast. The possibility of shifting votes intertemporally allows agents to concentrate their votes when preferences are more intense, and although the scheme will not achieve full efficiency, storable votes typically lead to ex ante welfare gains over non-storable votes. Welfare gains can be proven rigorously in the case of 2 voters. With more voters, counterexamples can be found, but the analysis suggests that the welfare improvements should continue to hold if one of the following conditions is satisfied: (i) the number of voters is above a minimum threshold; (ii) preferences are not too polarized; (iii) the horizon is long enough.     

Do universities knowledge spillovers impact on new firm’s growth? Empirical evidence from UK

The paper explores the effect of scientific institutions on firm’s growth, coupling regional science and entrepreneurship approaches. We focus on the role of universities, largely considered in the literature as the main source of knowledge spillovers. To this purpose, we centre our attention on UK public companies on the Alternative Investment Market (AIM), a market dedicated to young and growing companies in both science and non-science based industries. In the paper we investigate the growth determinants of 231 listed firms which have gone public during the period going from 1995 to 2006. To our purposes, in the empirical analysis we use the Gibrat’s Law of Proportionate Effects model. The results supports the hypothesis that, controlling for firm’s idiosyncratic factors and external forces, both universities knowledge input and output are important determinants of the growth of entrepreneurial firms listed on the AIM.

Cheating in markets: A laboratory experiment

We develop a two-market model under three conditions: autarky, frictionless free trade, and free trade with cheating. With cheating, buyers can underpay by π% in cross-market trades and sellers can deliver π% of full value. We solve for competitive equilibrium with cheating and obtain novel testable predictions on price, volume and surplus. We test these in a laboratory experiment using parameters intended to challenge the theory. The results are generally consistent with competitive equilibrium. We find evidence of price unification, market segmentation, a cross-market volume of trade lower under cheating than in frictionless free trade, but a higher overall volume.     

Market power under income polarization

We study the reaction of a monopolistic firm to distributive shocks which lead to income polarization. We show that the movements in the set price and in the sold quantity depend on the served market share. In particular, we identify a region of parameters where the optimal markup moves in the opposite direction of market demand: in this respect, distributive shocks can provide an explanation for countercyclical movements of the markup.     

Foreign Human Capital and Total Factor Productivity: A Sectoral Approach

We analyze the role of migrants in productivity growth in the three largest European countries—France, Germany and the United Kingdom—in the years 1994–2007, using Total Factor Productivity. Unlike previous research, which mainly employs a regional approach, our analysis is at the sectoral level: this allows to distinguish the real contribution of migrants to productivity from possible inter-sectoral complementarities, which might also foster growth. We control for the share of migrants and the different components of human-capital, such as education, age and diversity, and adopt instrumental variables strategies to address the possible endogeneity of migration. The results show that migrants contribute to the productivity of the sectors in which they are employed, but with important differences: highly-educated migrants show a larger positive effect in high-tech sectors, and to a lesser extent in services sector. The diversity of countries of origin contributes to productivity growth only in the services sectors.     

Exploring the determinants of green bond issuance: Going beyond the long-lasting debate on performance consequences

In recent years, the need to create new financial tools to mobilize private capital and generate suitable resources to face both social and environmental challenges led to the development of new tools and ideas. In this context, green bonds have emerged as a new financial tool to better respond to sustainability themes. This study is the first attempt to explore in depth the determinants of green bond performance. We focused on three perspectives: the specific characteristics of projects financed through a green bond, the broader firm-specific corporate sustainability-oriented strategy of the firm, and a country-level perspective analyzing the country-specific determinants of green bond performance. To test the hypotheses a sample of 306 corporate green bonds issued by 85 companies and referring to 1,788 green projects between 2013 and 2016, were retrieved from the Bloomberg database. The results provide interesting theoretical and practical implications for green bond issuers as well as investors and governments interested in green bonds.
