Research Paper No. 2004/34 Changes in Spatial Income Inequality in the Philippines An Exploratory Analysis

The purpose of this paper is to establish some basic facts about income inequality in the Philippines, with a special focus on the importance of spatial income inequality. Despite major fluctuations in macroeconomic performances, income inequality remained relatively stable during the years 1985-2000. Spatial inequality accounts for a sizable but not overwhelming portion of the national-level income inequality, and the relative importance of spatial inequality was declining over time. We also find that mean income levels across provinces were converging at a much faster rate than those observed in currently developed countries

Assessing the Effect of High Performance Computing Capabilities on Academic Research Output

This paper uses nonparametric methods and some new results on hypothesis testing with nonparametric efficiency estimators and applies these to analyze the effect of locally-available high performance computing (HPC) resources on universities efficiency in producing research and other outputs. We find that locally-available HPC resources enhance the technical efficiency of research output in Chemistry, Civil Engineering, Physics, and History, but not in Computer Science, Economics, nor English; we find mixed results for Biology. Out research results provide a critical first step in a quantitative economic model for investments in HPC

Abstract This paper reports the results of experiments testing prevalence of nonneutral ambiguity attitudes and how these attitudes change as a result of interpersonal interactions. To address the first question we conducted experiments involving individual choice between betting on ambiguous and unambiguous events of the subject’s choice. We found that a large majority of subjects display ambiguity neutral attitudes, many others display ambiguity incoherent attitudes, and few subjects display either ambiguity-averse attitudes or ambiguity-seeking attitudes. To address the second question we designed a new experiment with a built-in incentive to persuade. We found that interpersonal interactions without incentives to persuade have no effect on behavior. However, when incentives were introduced, the ambiguity neutral subjects were better able to persuade ambiguity seeking and ambiguity incoherent subjects to adopt ambiguity neutral choice behavior and, to a lesser extent, also ambiguity averse subjects. We are grateful to Stefan Trautmann, Peter Duersch, Luca Rigotti and an anonymous referee for their useful comments. We also benefited from comments and suggestions of the participants of the conference on “Ambiguity: Theory and Experiments, ” at the Center for the Economic Analysi
