We present a restriction on the domain of individual preferences that is both necessary and sufficient for the existence of a social choice rule that is continuous, anonymous, and respects unanimity. The restriction is that the space of preferences be contractible. Contractibility admits a...

In this paper I describe certain results that were obtained in the UNITAR project based on a model I have specified for studying the relationship between international terms of trade and domestic income distributions of the exporting countries within the South. In particular, I shall concentrate...

We study properties of the solutions to a parametrized constrained optimization problem in Hilbert spaces. A special operator is studied which is of importance in economic theory; sufficient conditions are given for its existence, symmetry, and negative semidefiniteness. The techniques used are...

Using Japanese prefecture-level data for the years 1979 and 1996, I explore the extent to which inequality, age heterogeneity, and human capital have an effect upon neighborhood trust, which is ordinarily considered as a kind of particularized trust. The major findings are as follows: (1) Income...

This paper develops a dynamic model of North-South trade in which environment plays an important role. Our model is based on Chichilnisky North-South model for the macroeconomic interaction between two sectors of the world economy. The latter was introduced in a static context. We introduce...

Oil price behavior has changed dramatically in the last twenty years. These changes can be explained rather simply in terms of the delayed responses of supply and demand to prices, and in terms of changes in the rate of discovery of reserves. This analysis can be used to forecast possible future...

In the present paper, the inverted-U shape relationship between growth and inequality found in Chen(2003), is reexamined. We decompose productivity growth into efficiency improvement, capital accumulation and technological progress and then ascertain their determinants by employing a fixed...

This paper revisits the aggregation theorem of Chichilnisky (1980), replacing the original smooth topology by the closed convergence topology and responding to several comments (N. Baigent (1984, 1985, 1987, 1989), N. Baigent and P. Huang (1990) and M. LeBreton and J. Uriarte (1900 a, b)....

The paper proposes two axioms that capture the idea of sustainable development and derives the welfare criterion that they imply. The axioms require that neither the present nor the future should play a dictatorial role. Theorem 1 shows there exist sustainable preferences, which satisfy these...

This paper examines the cubic form hypothesis and the flying geese pattern hypothesis of income distribution. We use time series data for the Gini coefficients of Korea for 1961-2006 and panel data calculated based on a household income survey for the period 1998-2003. We show; (1) The Korean...
