International Trade, OECD Membership, and Religion

Transaction costs in trade gravity equation are proxied by the distance that separates two trading partners, under the assumption that the distance elasticity is the same across all trading partners. We show that distance elasticity, however, critically depends on whether trading partners are industrial countries (i.e., members of the OECD) or share same religion. These heterogeneities are both statistically and economically significant. For instance, expected trade flows are the largest when an OECD member trades with a non-member and both are non-religious. Expected trade flows fall as much as by 62.9% between two non-religious, non-OECD members. Expected bilateral trade drops by 48.1% when both countries in the pair are OECD members while one is Christian and the other is Islamic. Both religion and OECD membership significantly affect the typical transaction costs implied by the gravity equation. JEL Classification Number: F13     

Are Mainstream and Heterodox Economists Different? An Empirical Analysis

We explore the differences between mainstream and heterodox economists based on the responses to a questionnaire from a representative sample of Italian economists. Using different definitions for mainstream and heterodox economics, we compare the individual and academic characteristics of the economists belonging to these groups. We measure the within and between disagreement for each group and we test whether belonging to one or the other group predicts differences in economists' opinions on economic policy. Results show that: 1) mainstream and heterodox economists differ as to individual and academic characteristics and political views; 2) the disagreement within heterodox economics is lower than within mainstream economics; 3) some of commonly used ways of grouping heterodox and mainstream schools of thought have little explicative power in relation to individual opinions; 4) on critical economic policies, the opinions of heterodox and mainstream economists are significantly different even after controlling for a number of individual characteristics, including political opinions.     

Assessing students’ equality of opportunity in OECD countries: the role of national- and school-level policies

This article analyses the relationship between equality of opportunity and the characteristics of the educational system, jointly considering country- and school-level policies. Because school social environment represents a fundamental channel in shaping educational opportunities, we consider all policies, recorded in PISA 2012 dataset, that affect the sorting of students to schools. We show that including sorting policies enriches the explanation of the socio-economic gradient, that is, the association between students’ performances and parental background, with respect to previous studies including only country-level features. The negative impact of early tracking on equality of opportunity is overvalued without including other sorting policies, while grouping students’ within-school by ability increases the socio-economic gradient and a greater students’ heterogeneity in the school reduces the gradient.
