Usability in product design--the importance and need for systematic assessment models in product development--Usa-Design Model (U-D) ©

In product design, human factors are considered as an element of differentiation given that today's consumer demands are increasing. Safety, wellbeing, satisfaction, health, effectiveness, efficiency, and other aspects must be effectively incorporated into the product development process. This work proposes a usability assessment model that can be incorporated as an assessment tool. The methodological approach is settled in two stages. First a literature review focus specifically on usability and developing user-centred products. After this, a model of usability named Usa-Design (U-D?) is presented. Consisted of four phases: understanding the use context, pre-preliminary usability assessment (efficiency/effectiveness/satisfaction); assessment of usability principles and results, U-D? features are modular and flexible, allowing principles used in Phase 3 to be changed according to the needs and scenario of each situation. With qualitative/quantitative measurement scales of easy understanding and application, the model results are viable and applicable throughout all the product development process.     

Rebates, inventories, and intertemporal price discrimination

We demonstrate that universally redeemed rebates can increase manufacturer profits by reducing the incentives of downstream retailers to hoard inventories when optimal wholesale prices vary predictably over time. By bypassing retailers and making direct contracts with buyers, the manufacturer can increase the variations in effective prices paid by consumers without concomitantly creating larger incentives for retailers to hold inventories. During profitable, high-demand periods, manufacturer revenues are ordinarily constrained by'competition'from retailer inventories, thus limiting profits. However, by selectively offering rebates to consumers while maintaining high wholesale prices, low-demand periods can be accommodated without inducing retailer hoarding.     

Finance and innovation in British small independent firms

This paper is concerned with the effects of internal and external capital investment funding patterns on the innovativeness of British small independent firms. By using a combined sample of firms from the relatively prosperous South East and the more problematic Scottish development region, an additional diverse regional economic perspective is given to data initially presented in a national context. Beyond a presentation of the extent of external borrowing, the paper seeks to establish the characteristics of firms obtaining external funds and to assess whether this external capital borrowing sub-sample is mainly comprised of low technology firms in decline, or of high technology firms fueling innovation-led expansion. Data is included on the role of both public and private loan agencies in the external funding process. Conclusions are based on the pattern of results and focus on ways in which the delivery of financial aid might be improved to assist expansion, particularly in fast growing high technology small firms.     

Pretrial negotiation, litigation, and procedural rules

We model the civil dispute resolution process as a two-stage game with the parties bargaining to reach a settlement in the first stage and then playing a litigation expenditure game at trial in the second stage. We find that the English rule shifts the settlement away from the interim fair and unbiased settlement in most circumstances. Overall welfare changes are in favor of the party who makes the offer in the pretrial negotiation stage. Lawyers however, always benefit from the English rule, because fee shifting increases the stake of the trial and thus intensifies the use of the legal service.
