In this note we correct and improve a zero duality gap result in extended monotropic programming given by Bertsekas in [1].

Numerous studies have been carried out to find out the factor of impulse purchase components in different environment such as on website, mobile, traditional retail store and traditional television. However, those studies are not dedicated to design models to increase impulse purchase on iTV advertising. Therefore, an analysis involving five existing models of website advertising environment, t...

This study attempts to fill this gap: it surveys the most recent contributions to the mainstream trade economics literature, assesses their relevance for Latin America and concentrates on specific quantita...

Motivated by the concern that the recent surge in inflation could retard growth, the paper revisits the nexus between inflation and growth from the perspective of an emerging economy, India. Examining this relationship using a wavelet multi resolution analysis with varying time scale decomposition suggests a strong and persistent negative relationship between growth and inflation for a short ti...

Despite the rise of dual-income households in the United States and a narrowing of the nation’s gender wage gap, we find that many men and women still prefer the husband to be the primary breadwinner. To help explain intra-marital wage preferences, we argue for a new construct, gender determinism, which captures the extent to which a person believes gender categories dictate individual characte...

We define a family of natural decompositions of Sturmian words in Christoffel words, called reversible Christoffel (RC) factorizations. They arise from the observation that two Sturmian words with the same language have (almost always) arbitrarily long Abelian equivalent prefixes. Using the three gap theorem, we prove that in each RC factorization, only 2 or 3 distinct Christoffel words may occ...
