AGGREGATION WITHOUT SEPARABILITY: TESTS OF U.S. AND MEXICAN AGRICULTURAL PRODUCTION DATA [PDF]

The generalized composite commodity theorem (Lewbel 1996) is used to test for consistent aggregation of U.S. and Mexican agricultural production data in each of the categories for which earlier tests rejected homothetic separability.

THE GENERALIZED COMPOSITE COMMODITY THEOREM AND FOOD DEMAND ESTIMATION [PDF]

This paper reports tests of aggregation over consumer food products and estimates of aggregate food demand elasticities. Evidence that food demand variables follow unit root processes leads us to build on and simplify tests of the Generalized Composite ...

Trends in hours and economic growth. [PDF]

We study long-run trends in market hours of work and employment shifts across economic sectors driven by uneven TFP growth in market and home production. We focus on the structural transformation between agriculture, manufacturing and services and on the

A forewarning indicator system for financial crises: the case of six Central and Eastern European countries [PDF]

We propose a measure of the probability of crises associated with an aggregate indicator, where the percentage of false alarms and the proportion of missed signals can be combined to give an appreciation of the vulnerability of an economy.

Amino Acid Composition drives Peptide Aggregation: Predicting Aggregation for Improved Synthesis

Peptide aggregation is a long-standing challenge in chemical peptide synthesis, limiting its efficiency and reliability. Although data-driven methods have enhanced our understanding of many sequence-based phenomena, no comprehensive approach addresses so-called “non-random difficult couplings” (generally linked to aggregation) during solid-phase ...
