Case Study: The Engineering Economics of RFID in Specialized Manufacturing

Calibrated tools are essential to producing highly specialized, defect-free parts. These tools are used in many processes in specialty manufacturing operations. Personnel could use the improper tool if the calibrated tool has been lost or stolen. This results in reduced business productivity and increased cost due to poor quality. This study demonstrates the cost effectiveness of using a radio frequency identification (RFID) system to track calibrated tools throughout a production facility. The costs of RFID tool tracking are described and return on investments of plausible scenarios are determined. Also, sensitivity analysis is performed utilizing spider plot and tornado diagrams.     

The Effect of Enhancing Workers’ Employability on Small and Medium Enterprises: Evidence from Spain

In this paper, we analyse the effect of promoting workers’ employability on labour productivity. To this end, we adapt a simple efficiency-wage model that includes the employer’s decision on the provision of opportunities for enhancing workers’ employment prospects in a context of job insecurity. We show that (i) by facilitating workers’ employability, the firm increases its labour productivity; and (ii) the higher the job uncertainty the higher the productivity gains due to the increase in employability. One of the advantages of our model is that it is simply enough to allow us to formulate two testable hypotheses, namely (i) the increase of jobs’ potential to enhance workers’ employability results in higher level of workers’ effort, and (ii) the provision of employability is more profitable for small and medium enterprises (SMEs) than for large firms. More precisely, SMEs should obtain higher effort levels from employees by fostering workers’ employability than large firms. We provide some evidence supporting these hypotheses from a highly representative sample of Spanish manufacturing firms. This research has been funded by the Spanish Ministry of Education and Science, project SEJ2004-07242-C03-02.     

Family control and adjustment to the optimal level of cash holding

Given the predominance of family control in most European corporations, understanding how this type of ownership affects firms’ cash holding policy is important. The literature has yet to address this subject satisfactorily; therefore, we outline a way to model how family firms define their cash policy, specifically, the way in which they adjust their cash holding to an optimal level. We base our analysis on trade-off theory and the precautionary motive for holding cash. Our empirical results show that family firms adjust their cash holding level more aggressively than non-family firms, and, therefore, family firms are capable of achieving optimal cash holding faster and more efficiently than non-family firms. Further, we find that family firms have a heterogeneous cash policy; in particular, young family firms, financially constrained family firms, and family firms that operate in countries with strong investor protection adjust their cash holding more aggressively.     

The antecedents of complaint behaviour for Brazilian and French consumers of services

Using a cross‐cultural approach, this study investigates customer satisfaction after a service failure and recovery experience, considering (i) the influence of perceived justice on satisfaction; (ii) the impact of satisfaction on consumer repurchasing and complaint intentions; (iii) the moderating role of the customer cultural orientation; and (iv) the relevance of contextual variables. Based on a survey of 298 consumers from Brazil and France, the results indicated that (i) distributive and interactional justice influenced satisfaction; (ii) satisfaction was a significant predictor of repurchase intentions; (iii) satisfaction influenced third‐party, private and voice responses; and (iv) the level of the customer relationship, the severity of the failure and the responsiveness of the firm were significant contextual variables. Moreover, the individual‐level analysis suggested that only power distance cultural orientation was a significant moderator.     

Can The World Trading System Accommodate More East Asian Style Exporters?

A CGE model of world trade is used to examine whether many developing countries can simultaneously expand manufactures exports along East Asian lines without suffering serious terms of trade decline and consequent welfare loss. Experiments are performed in which manufactures exports are expanded for each developing region in turn and for all regions simultaneously. When driven by productivity gains in manufactures exports production, welfare gains are found to be significant and stable, even enhanced by parallel advances in other developing regions: i.e. export growth is mutually reinforcing as a result of extensive South-South manufactures flow, a pattern that is intensifying.

Altruism,fertility, and the value of children: Health policy evaluation and intergenerational welfare

This paper accounts for the value of children and future generations in the evaluation of health policies. This is achieved through the incorporation of altruism and fertility in a “value of life” type of framework. We are able to express adults' willingness to pay for changes in child mortality and also to incorporate the welfare of future generations in the evaluation of current policies. Our model clarifies a series of puzzles from the literature on the “value of life” and on intergenerational welfare comparisons. We show that, by incorporating altruism and fertility into the analysis of the recent U.S. experience, the estimated welfare gain of a young adult from reductions in mortality easily doubles.     

Simultaneous Models for Contingency Tables: A Reanalysis of Heatherton et al. (1997) Data on Eating Behavior

In panel studies, where a categorical response is measured attwo points in time, we can examine two kind of hypotheses regardingthe nature of change. The first is related with change at theindividual level (gross change) through the modelling of joint distributionof responses. The second is related with aggregate change (netchange) through the modelling of marginal distributions of responses.This paper describes a general approach to the analysis of two-wavepanel data based on Lang and Agresti's work (1994) that simultaneouslypermits the modelling of marginal and joint distributions of responses.This approach is illustrated with data from Heatherton et al.(1997) about change in dieting behaviour. These data were originallyanalyzed using the ² statistic to test independenceof responses. This paper shows how it is possible toobtain a better understanding of these data using the proposedmethodological approach.     

Measuring and forecasting retail trade in real time using card transactional data

We build big data retail trade indicators for Spain using high-dimensional card transaction data from one of the country’s biggest banks. The resulting indicators replicate the dynamics of the Spanish retail trade indices (RTI), regional RTIs (Spain’s autonomous regions), and RTI by retailer type (distribution classes) released by the Spanish National Statistics Institute. The new indicators not only have a higher frequency (daily data) and higher geographical and sectorial breakdown but are also shown to improve nowcasting and forecasting power for the official RTI, making them key variables to monitor consumption.     

Endogenous innovations in the pharmaceutical industry

This paper addresses the creation of new products in the US pharmaceutical sector, during the second half of the 20th century. We indicate that the continuous increases in population, and thus in the market size of this sector, play a fundamental role in explaining the large creation of new drugs during that period. We also argue that population and market size can be endogenously determined through the impact of drugs over the mortality rate. Hence, these two effects reinforce each other, producing decrements in the mortality rate and increments in the stock of drugs over time. We obtained the set of new molecular entities approved by the FDA during the second half of the 20th century and we decomposed the data in a panel of 15 therapeutic categories over time. Using this data, we tested our hypotheses using different econometric methods. The results support the hypothesis and are consistent across methods.
