Introduction: The high-resolution Al-Mg extinct chronometer (t1/2 = 0.72 Myr) has been applied extensively towards constraining the chronology of the early Solar System. In particular, there have been many investigations of the Al-Mg systematics in the calciumaluminum-rich inclusions (CAIs), which has been used to infer the age of the Solar System since these objects represent the earliest-form...

This paper offers additional insights on the interactions between economics and politics in Portugal. We use an unexplored data set consisting of monthly polls on vote intentions for the main political parties in Portugal, since 1986. Results indicate that: (1) socialist governments had less electoral support than social democratic governments; (2) social democratic governments enjoyed a honeym...

This paper analyses the e¤ects of reducing unfunded social security in a closed economy that consists of a service sector and a commodity sector. It is shown that if old agents mainly demand labour intensive services, a modest decrease of the pay-as-you-go pension scheme still raises long-run utility as long as the economy is dynamically e¢cient. However, entirely privatising the social securit...

We study the interplay between competition and trust as efficiencyenhancing mechanims in the private provision of money. With commitment, trust is automatically achieved and competition ensures efficiency. Without commitment, competition plays no role. Trust does play a role but requires a bound on efficiency. Stationary inflation must be non-negative and, therefore, the Friedman rule cannot be...

Inflation targeting needs to be supplemented by an economic growth target so that central banks will not adopt monetary policy which results in stagnation. There is no guarantee that the economy will move towards full employment by itself when the inflation rate is kept between two to three per cent. Monetary policy does not have a comparative advantage in achieving price stability. Svensson's ...

Child Poverty and Changes in Child Poverty in Rich Countries Since 1990 This paper documents levels and changes in child poverty rates in 12 OECD countries using data from the Luxembourg Income Study project, and focusing upon an analysis of the reasons for changes over the 1990s. The objective is to uncover the relative role of income transfers from the state in determining the magnitude and d...

Migration, Transfers and Child Labor We examine agricultural child labor in the context of emigration, transfers, and the ability to hire outside labor. We start by developing a theoretical background based on Basu and Van, (1998), Basu, (1999) and Epstein and Kahana (2008) and show how hiring labor from outside the household and transfers to the household might induce a reduction in children’s...

A New Framework for the Analysis of Inequality This paper presents a new framework for analyzing inequality that moves beyond the anonymity postulate. We estimate the determinants of sectoral choice and the joint distributions of outcomes across sectors. We determine which components of realized earnings variability are due to uncertainty and which components are due to components of human dive...

This study draws on the Millennium Cohort Study to explore the housing and neighbourhood circumstances of children born in England in 2000 at the age of 5 in 2006. The majority of children experienced good housing conditions. Those in social rented homes, and to a lesser extent in private rented homes too, were markedly disadvantaged in terms of family circumstances and neighbourhood deprivatio...
