ABC analysis is a popular and effective method used to classify inventory items into specific categories that can be managed and controlled separately. In traditional ABC analysis the inventory items are categorized in to A ,B and C classes based on the annual dollar usage. The annual dollar usage is determined as the product of unit cost of each item and its annual demand. The items are arrang...

Exact consumers surplus and deadweight loss are the most widely used welfare and economic efficiency measures. These measures can be computed from demand functions in straightforward ways. Nonparametric estimation can be used to estimate the welfare measures. In doing so it seems important to account correctly for unobserved heteroeneity given the high degree of unexplained demand variation oft...

This paper examines the potential causes of the “ripple effect” of minimum wages. This wage spillover is thought to result from labor demand substitution: where the rising minimum increases the demand for more-skilled workers who become relatively inexpensive. However, the rising minimum also affects the relative wages across hedonically distinct occupations because it lowers compensating wage ...

We examine empirically the effect of international outsourcing on labour demand at the level of the individual plant. We do so by estimating a dynamic model of plant level labour demand, using a Generalised Method of Moments estimator. We use plant level data for the Irish Electronics sector, an industry that has expanded rapidly over the last decade and that has witnessed significant offshorin...

In this article we analyze the determinants of the functional distribution of government expenditure using for this purpose the models of the median voter's demand common in public choice literature. First of all, we review the economic literature on the factors affecting each component of government expenditure. Then, secondly, we develop a demand model of expenditure structure and we estimate...

We introduce a money demand motive in a life-cycle portfolio choice model and estimate the structural parameters that can generate limited stock market participation and plausible holdings of money, bonds and stocks. The model predicts an increase in bond holdings over the life cycle, and a declining share of money in portfolios as wealth increases. Both predictions are consistent with the data...

In this article we examine money demand issues using cross‐country data, for 48 countries over the 1980‐1995 period. In particular, we investigate conventional money demand functions, for both narrow and broad aggregates, and the role that insti tutions, financial structure and financial development may have in the demand for money. On the basis of possible heterogeneity within the cross-countr...

We explore the relevance of the risk attitude of managers to the investment-uncertainty relation. Higher moments of the distribution of net profits are used to measure the risk premium of the firm, from which we derive a proxy for the risk aversion of managers. Using an unbalanced panel of Dutch listed firms, we find that in general a low degree of risk aversion coincides with a positive impact...

A fundamental puzzle about human behavior is the low level of household investment in preventive health inputs. We conducted a field experiment testing advertising devices designed to increase demand for a life-saving health technology characterized by low uptake. Our results reveal highly elastic demand with respect to factors that lie outside of standard consumer demand models of health behav...
