Le disuguaglianze regionali nella distribuzione del reddito. Parte seconda: Un'analisi delle famiglie italiane a rischio di povertà
The aim of this paper is the analysis of vulnerability within families in nine regions of Italy and represents the second part of a research on regional inequalities in income distribution. Poverty tends to be a multi-dimensional concept and the use of monetary income as a single measure of welfare can be misleading. The concept of equality of living standards is a more correct definition, but it is far more elusive. Starting from the concepts of lacks of purchasing power, of financial and patrimonial protections and of opportunities to achieve economic resources, we can measure different dimensions of vulnerabilities between regional living standards. Then, we try to identify specific families’ types in which the previous lacks seem more frequent and spread: young couples with little children, families with children and only one parent and single old women are the most vulnerable families in most of the regions and on average for the whole country. Finally, we try some normative conclusions about the direction of welfare measures to reduce such factors of economic vulnerability within families and regional inequalities in Italy.
Why Italy's saving rate became (so) low?
The aim of this paper is to explain why a low and declining saving rate should be a problem in a world of free capital flows and increasing wealth. In Italy consumer households’ saving have been the main driver of economic stability and growth, funding investments and public debt, and despite international turbulences Italy was acknowledged as a high saving country until the early 1990’s. Ever since, however, households saving rate plunged, in spite of an increasing financial wealth, and our aim is to explain why: we suggest two main causes. The first is related to the economic policies implemented to deal with four major economic events, prompted by economic misalignments: a) the 1992’s currency crisis, b) the run-up to the Euro, c) the 2006’ turning point, preceding the 2008’s crisis, and d) the 2009’s public debt crisis and the following policy of fiscal consolidation. These four events were dealt with economic policies which overlooked the huge income and saving shifts from households to government and private sectors: rising tax burden, especially indirect taxes, freezing of nominal public expenditures and falling real wages were the main policy instruments, while a decreasing households’ income and saving was a primary consequences. Households have been struggling to smooth their standard of life drawing on their saving and wealth, but the effort became all the more difficult as the saving rate was falling below a critical level, increasing the probability of negative saving and debt. Gross national saving turned less than aggregate investment, prompting an increasing borrowing from abroad and a corresponding negative current account. The second cause is structural and covers two crucial issues: the first is the deep economy impacts of a changing age structure, as a consequence of a sudden fertility drop. The second issue is related to the falling households size composition jointly with the rising share of quasi-fixed costs necessary for a decent life. We show how and why a well designed Welfare State could help to restore income stability and saving, tackling the widespread problem of changing age structure in most countries.
Engineering bio-inks for 3D bioprinting cell mechanical microenvironment
Three-dimensional (3D) bioprinting has become a promising approach to construct­ing functional biomimetic tissues for tissue engineering and regenerative medicine. In 3D bioprinting, bio-inks are essential for the construction of cell microenviron­ment, thus affecting the biomimetic design and regenerative efficiency. Mechanical properties are one of the essential aspects of microenvironment, which can be char­acterized by matrix stiffness, viscoelasticity, topography, and dynamic mechanical stimulation. With the recent advances in functional biomaterials, various engineered bio-inks have realized the possibility of engineering cell mechanical microenviron­ment in vivo. In this review, we summarize the critical mechanical cues of cell micro­environments, review the engineered bio-inks while focusing on the selection princi­ples for constructing cell mechanical microenvironments, and discuss the challenges facing this field and the possible solutions for them.
