In this era of globalization and constant innovation, the life cycles of products are diminishing, which tends to cause dynamic behaviour in the system, and because of this, there is a constant introduction of new products in the market. Therefore, while developing inventory models for new products, it becomes necessary to consider dynamic parameters associated with the demand function and resp...

This paper argues that research in political ecology would benefit from more explicit and careful attention to the question of scale and scalar politics. Although political ecologists have extensively considered scale as a methodological question, they have yet to develop an explicit theoretical approach to scale as an object of inquiry. We highlight one principal drawback to this underdevelope...

I am cast on this panel as offering an economist’s view of the policy lessons to be drawn from the income maintenance experiments. That will be true enough if you take the word "an" seriously. I am indubitably a card-carrying economist. But I have the feeling that -on these particular matters at least -my views are not always those of the typical economist. Part of the difference, but only part...

Cohabitation has become so prevalent in Canada that it is now the most common mode of entry into conjugality. Yet in drawing comparisons across Canadian provinces, cohabitation is far more prevalent in the province of Quebec than elsewhere. With this in mind, the purpose of the current paper is three fold. First, we set out to briefly situate the recent growth in the number of common-law unions...

Starting in the 1960s, a number of academic works have focused in serial and distributed multi-echelon structures and in both deterministic and stochastic environments. Clark and Scarf (1960, 1962) developed a seminal work in which they presented optimal policies for a serial multi-echelon system. Schwartz (1973) studied a deterministic model having one warehouse and N retailers and showed that...

Policies to promote human capital formation have been advocated as a remedy for reducing the economy-wide problem of rising wage inequality. These policies are national in character and are designed to substantially alter the proportion of the work-force that is skilled. Yet the methods used to evaluate these policies are partial equilibrium in nature and do not take account of the consequences...
