Public Policy Evaluation, Social Risk and Pension Capital
di Mordecai Kurz pagine: 28 € 6,00
Abstract
Today’s demand for social insurance is supported by economic reasoning showing that private insurance markets do not provide efficient coverage for medical insurance, for inter-generational risk sharing and for income instability. It is unfashionable to say but government intervention in these areas is the solution and Conservative economic ideology is the problem. Hence, policy in the 21th century will focus on publically managed social insurance. In studying the problem of Social Security, I show it arises from changing demography which generated a deficit. Study of proposed solutions lead me to four conclusiones: (i) Privatization of Social Security is infeasible since system has a «Legacy Debt» of $11.6 trillion. (ii) Proposals to privatize Social Security are ideologically motivated and offer no real solution. (iii) Privatization is undesirable since it is not optimal to rely entirely on the markets to determine retirees’ incomes. Volatility of financial markets will result in unacceptable inter-generational income inequality.
Freedoms, institutions and sustainable human development according to Sen’s capability approach
di Marco Grasso, Stefano Pareglio pagine: 16 € 6,00
Abstract
The aim of this paper is to outline the role of instrumental freedoms and institutions in the achievement of sustainable human development, doing so according to the perspective of Sen’s capability approach. Each area of sustainability can be represented by a set of driving forces, response variables and state variables. State variables denote constitutive freedoms, the achieved functionings chosen from the capability set. Their variations are produced by driving force variables. The latter are, in their turn, influenced by response variables triggered by institutions and instrumental freedoms. We map a selected set of variables related to the environmental dimension in order to show how instrumental freedoms and institutions influence sustainable human development.
Food Safety and Governance Choices
di Gaetano Martino, Cristiano Perugini pagine: 26 € 6,00
Abstract
The paper aims at analyzing organizational issues in the supply of safe food. The relationship between organizational form and level of safety does not seem, satisfactorily or systematically, to have attracted researchers’ attention. The study of the influence of the characteristics of safe food is here developed within the theoretical framework provided by Transaction Costs Economics. Behavioural uncertainty and asset specificity are taken into account in order to analyze the influence of the characteristics of food on the choice of the structure of governance. The paper proposes the idea the hybrid forms are efficiently chosen by agents and preliminary empirical evidence is provided. The study thus provides necessary premises to develop the analysis both of liability and competition within complex relationships along supply chain.
Mercato del credito e imprese in un modello con agenti eterogenei
di Pasquale Cirillo, Pietro A. Vagliasindi, Giovanni Verga pagine: 32 € 6,00
Abstract
Recent economic literature indicates that imperfections in the credit market can amplify business fluctuations causing financial fragility. Starting from the framework of Greenwald and Stiglitz (1993) and Delli Gatti et al. (2005), we make a more careful model of the banking sector in Italy and its impact on firms’ investment behaviour in an economic model with heterogeneous agents. We focus on the productive sector, considering mainly risk neutral firms, facing capital increasing adjustment costs. One of our aims is to comprehensively examine all incomes from capital in a static equilibrium, in order to consider the corporate and individual levels in a unitary framework. In doing so, we take a first step towards building an operational micro-simulation model, which will allow us to replicate the main empirical evidence of the credit market and provide useful and concrete policy recommendations on monetary and fiscal systems and policies.
