Decentralisation is invariably among the recommendations that international organisations such as the World Bank make for an enhancement of social provisions, and particularly a better targeting of social assistance regimes, in Eastern and Central Europe. However, theoretical literature as wel...

We investigate how income inequality affects social welfare in a model of voluntary contributions to multiple pure public goods. Itaya, de Meza, and Myles (1997) show that the maximization of social welfare precludes income equality in a single pure public good model. In contrast, we show that...

This paper illustrates how Crossing Generalised Lorenz (GL) curves can be used to identify the best income distribution on social welfare grounds within a set of alternative income distributions generated by different policy options. It starts by illustrating two alternative income distributions...

In the US, defense R&D share of GDP has decreased significantly since 1960. To analyze the implications on economic growth and welfare, we develop an R&D-based growth model that features the commonly discussed crowding-out and spillover effects of defense R&D on civilian R&D. The model also...

This paper discusses methodological principles for social evaluation of tax systems and tax reforms when concern is primarily turned to who gains and who loses. The discussion is followed by an empirical analysis based on Italian household data. Using a household microeconometric labor supply...

This article studies the process from data acquisition to policy decision in relation to an optimum policy on global warming. Policymakers must be reasonably skeptical before proposing remedies to curb warming, but policymakers cannot await the final proof of any proposal's merit. Balancing...

In this paper, we introduce and apply a general framework for evaluating long-term income distributions according to the Equality of Opportunity principle (EOp). Our framework allows for both an ex-ante and an ex-post approach to EOp. Our ex-post approach relies on a permanent income measure...

This paper proposes a two-step aggregation method for measuring long-term income inequality and income mobility, where mobility is defined as an equalizer of long-term income. The first step consists of aggregating the income stream of each individual into a measure of permanent income, which...

We show how normative standpoints determine optimal taxation of wealth. Since wealth is not equal to capital, we find very different welfare implications of land rent-, bequest- and capital taxation. It is mainly land rents that should be taxed. We develop an overlapping generations model with...
