This study investigates whether and to what extent further unemployment experience for youths who are already long-term unemployed imposes a penalty on subsequent labour market outcomes. We propose a flexible method for analysing the effect on wages aside of transitions from unemployment and employment within a multivariate duration model which controls for selection on observables and unobserv...

This Working Paper should not be reported as representing the views of the IMF. The views expressed in this Working Paper are those of the author(s) and do not necessarily represent those of the IMF or IMF policy. Working Papers describe research in progress by the author(s) and are published to elicit comments and to further debate. A reduced-form model approach was used to estimate the trade ...

In this paper we extend the Lucas (1988) endogenous growth model to include sector-specific external effects and depreciation in both sectors. We derives analytically, the necessary and sufficient conditions for the existence of balanced growth paths and equilibria. We furthermore demonstrate that in contrast to the original model, with the addition of external effects in both the production an...

The efficiency results of marginal-cost pricing have been used to justify the imposition of regulatory policy tools to determine optimal pricing. In the more sophisticated form, Ramsey pricing methodology is recommended as a pricingpolicy tool. These methods are static. Nevertheless, they are applied to major infrastructure industries such as telecommunications. At best, these methods assume pr...

in an attempt to determine the chemical losses of three common molluscicides, i.e. cuso4, napcp and bayer –73, in stagnant water, a solution of each of this molluscicide was applied to one or more b.truncatus habitats and outdoor aquariums. the concentration of each molluscicide in these water bodies was determined immediately after application and at fixed time intervals thereafter. the concen...

a r t i c l e i n f o Recent facts on the importance of corporate losses motivate more careful study of the impact of tax incentives for investment on firms that lose money. I model firm investment decisions in a setting featuring financing constraints and carrybacks and carryforwards of operating losses. I estimate investment responses to tax incentives allowing effects to vary with cash flows...

extensive research has been devoted to economic production quantity (epq) problem. however, little atten-tion has been paid to problems where depreciation cost and process quality cost must be considered, simulta-neously. in this paper, we consider the economic production quantity model of minimizing the annual total cost subject to depreciation cost and process quality cost, where depreciation...

ost assets depreciate, losing value over time as a result of wear and tear, age, or obsolescence. Corrosion, like depreciation, results in the often hidden cost of a non-cash expense — measurable in terms of reduced operating life — that reduces the value of assets. Many engineers in the chemical process industries (CPI) see corrosion on a “straight-line basis” in terms of repair, maintenance a...

While previous studies have examined how the development of organizational knowledge (organizational learning) affects quality performance, we investigate how the depreciation of organizational knowledge (organizational forgetting) affects vendor quality performance. We use data on 2,732 quality improvement initiatives undertaken by a car manufacturer at 295 vendors. We find that organizational...
