We propose and analyze an effective model for the Multistage Multiproduct Advertising Budgeting problem. This model optimizes the advertising investment for several products, by considering cross elasticities, different sales drivers and the whole planning horizon. We derive a simple procedure...

This paper examines the impact of declines in adult mortality on growth in an overlapping generations model. With public education and imperfect annuity markets, a decline in mortality affects growth through three channels. First, it raises the saving rate and thereby increases the rate of...

Plastic film mulching is widely employed to improve crop yields. Mulching for the entire crop growth period is a widespread practice. However, a shorter plastic film mulching duration is suggested for obtaining larger grain yield recently. To quantify the effects of plastic film mulching...

A simple and hydrazine-free solution-based approach for depositing Cu2ZnSnS4 (CZTS) and Cu2ZnSn(S,Se)4 (CZTSSe) absorber layers is reported. The process involves incorporating metal salts (Cu(CH3COO)2, Zn(CH3COO)2, SnCl2) and thiourea into a single pyridine-based solution, spin-coating a...

Intraclass correlation coefficients (ICC) are employed in a wide range of behavioral, biomedical, psychosocial, and health care related research for assessing reliability of continuous outcomes. The linear mixed-effects model (LMM) is the most popular approach for inference about the ICC....
