Changes in the strategic management of technology: results of a global benchmarking study

This contribution analyses main changes in the strategic management of technology of the world's most technology-intensive companies from western Europe, North America and Japan. The results presented here are based on a literature review and a survey which show the following main results: first, R&D and technology have become key cornerstones of corporate and business strategy. Second, there is a growing tendency to acquire technology from external sources throughout the sample. Third, internationalization of R&D plays a very important role in the strategies of the large companies investigated and the data shows that it will certainly gain further momentum. However, internationalization of R&D is confined to the Triad regions and is not 'global'. Based on our analysis, cornerstones of a future generation of R&D/technology management are developed.     

Re-employment probabilities over the business cycle

Using a Cox proportional hazard model that allows for a flexible time dependence in order to incorporate business cycle effects, we analyze the determinants of re-employment probabilities of young workers in the USA from 1978–1989. We find considerable changes in the chances of young workers finding jobs over the business cycle despite the fact that personal characteristics of those starting jobless spells do not vary much over time. Therefore, government programs that target specific demographic groups may change individuals’ positions within the queue of job seekers, but may only have a more limited impact on average re-employment probabilities. Living in an area with high local unemployment reduces re-employment chances as does being in a long spell of non-employment. However, the damage associated with being in a long spell seems to be reduced somewhat if a worker is unemployed in an area with high overall unemployment.

Investment in Tourism Market: A Dynamic Model of Differentiated Oligopoly

We present a theoretical dynamic model in tourism economics, assuming that the market for tourism is an oligopoly with differentiated products. Destinations can invest in order to improve their stock of physical, natural or cultural resources. Tourism flows yield current revenues, but they are usually detrimental for the stock of resources. We find the solution of the dynamic model, and in particular we find the open-loop Nash equilibrium of the game among destinations, under alternative settings, depending on whether the degree of differentiation among destinations is exogenous or endogenous. In particular, under the latter case, an increase of the number of destinations leads to a higher degree of product differentiation in steady state.     

Disinflation in a DSGE perspective: Sacrifice ratio or welfare gain ratio?

When used to examine disinflation monetary policies, the current workhorse dynamic stochastic general equilibrium model of business cycle fluctuations is able to quantitatively account for the main stylized facts in terms of recessionary effects and sacrifice ratio. We complement the transitional analysis of the short-run costs with a rigorous welfare evaluation and show that, despite the long-lasting economic downturn, disinflation entails non-zero overall welfare gains.     

Do your brains help you out of unemployment?

This study examines the relationship between individuals’ cognitive abilities, unemployment propensity and unemployment entry or exit. Cognitive skills only weakly affect unemployment propensity and contribute little to individual heterogeneity. They, however, help employed males to stay out of unemployment.     

The Costs of Financial Crises: Resource Misallocation,Productivity, and Welfare in the 2001 Argentine Crisis

Financial crises in emerging market countries appear to be very costly: both output and a host of partial welfare indicators decline dramatically. The magnitude of these costs is puzzling both from an accounting perspective – factor usage does not decline as much as output, resulting in large falls in measured productivity – and from a theoretical perspective. With the aim of resolving this puzzle, we present a framework that allows us to do the following. First, we account for changes in a country's measured productivity during a financial crisis as the result of changes in the underlying technology of the economy, the efficiency with which resources are allocated across sectors, and the efficiency of the resource allocation within sectors, driven both by reallocation amongst existing plants and by entry and exit. Second, we measure the change in the country's welfare resulting from changes in productivity, government spending, the terms of trade, and a country's international investment position. We apply this framework to the Argentine crisis of 2001 using a unique establishment level dataset and we find that more than half of the, roughly, 10 percent decline in measured total factor productivity can be accounted for by deteriorations in the allocation of resources both across and within sectors. We measure the decline in welfare to be of the order of one‐quarter of one year's gross domestic product.     

What nutrition label to use in a catering environment? A discrete choice experiment

Worksite and university canteens are increasingly used for daily main meal consumption. Following the use of front-of-pack nutrition labels on pre-packed foods, the provision of easily accessible nutrition information on foods prepared and consumed out of home is a highly topical policy issue with the potential to help consumers making better informed and more healthy food choices when eating out. Information that is presented in a format preferred by the target group is more likely to be used. A sample of 1725 university canteen users participated in a web-based choice experiment designed to identify and understand individual preferences for alternative nutrition labels on canteen meals. Participants valued the presence of nutrition labels on canteen meals and showed a preference for more detailed formats. Ability and motivation to process information as well as socio-demographics explained differences in label preferences. Observed decreasing marginal utility from combinations of two simple label formats as well as from combinations of two detailed formats, signalled information insufficiency versus information overload, respectively. In order to satisfy most canteen users’ information needs, a nutrition label that contains basic Guideline Daily Amount (GDA)-type of numerical information in combination with familiar visual aids like stars and colour codes is proposed to be used in university canteens.     

Contract farmer and poultry farm efficiency in Bangladesh: a data envelopment analysis

The objective of this article is to determine the efficiency of the poultry farm in Bangladesh and to assess the influence of contract farming system, using a data envelopment analysis. Seventy-five commercial poultry farms (25 and 50 independent and contract farms, respectively) were randomly selected. The results reveal that efficiency scores vary across sample farms. To explain some of these variations, the efficiency scores were regressed on some human capital variables and farming system using a Tobit model. The study also estimates elasticities to provide the information on the magnitude of the influence of variables on Technical Efficiency (TE), Allocative Efficiency (AE) and Economic Efficiency (EE). The results show that the contracting system is positively and significantly related to the farm's TE, AE and EE. This is expected because under contractual agreement, in order to obtain sufficient supplies of the right quality of poultry meat at the right time, the company provides technical know how assistance through company's recruited supervisor, production inputs and services, and production credit along with intensive supervision, which in turn improves farm efficiency. Thus, by receiving technical know how contract farmers have gained more knowledge on their resource and practices, which enables them to use resources more efficiently. Empirical results can provide crucial information to policy makers that improve poultry farm efficiency.
