Transnational involvement and social integration

Abstract In this article we offer a quantitative examination of the extent to which migrants from various countries are involved in transnational activities and have transnational identifications. The study is based on a survey of 300 immigrants (from the USA, Japan, Iraq, former‐Yugoslavia, Morocco and the Dutch Antilles) living in the Netherlands. The respondents are deliberately chosen to include different categories of immigrants. Transnational activities constitute a substantial part of their lives and are to a large extent socio‐cultural. Many migrants also transfer money abroad. Professional economic activities were rare and mainly limited to the American group. As a whole, our respondents identify more with other compatriots living in the Netherlands than with people living outside the Netherlands. The research also found that transnational involvement in general does not impede ‘immigrant integration’. Migrant groups that are known as poorly integrated into Dutch society are not more involved in transnational activities and have no stronger identifications with the country of origin than other groups. However, within the Moroccan and Antillean groups those respondents with the weakest labour market position identify more strongly with the country of origin than others. Strong identifications with compatriots living elsewhere and withdrawal from Dutch society may reinforce their poor labour market integration     

Simulation-based production schedule generation

Abstract

While simulation has been used in manufacturing for many years, predominantly for facility design, it is within the last few years, that simulation languages have been developed to a point where they can be used on a day-to-day basis to generate schedules and predict their performance. This paper describes our use of different modelling techniques to develop a production schedule generation system. An example describing a system for a small- to medium-sized order producing company using SIMAN/CINEMA is included. While addressing the shortcomings of existing scheduling systems it is shown how the approach taken is a feasible way of creating a dynamic goal-driven simulation-based production scheduler. The paper does not aim to describe an ‘off the shelf’ scheduling system product, but rather to give an overview to methods, techniques and experiences which enable us rapidly to tailor a simulation-based scheduling system to the specific needs of a company.     

Governance Structures,Multidimensional Efficiency and Firm Profitability

Using a panel data set of 361 German corporations for the period 1991–1996 we test the hypothesis that firms with more efficient governance structures have higher profitability. To determine efficiency we compare firms with respect to ownership concentration, the identity of owners, capital structure, investment and firm growth by a multi-input/multi-output Data Envelopment Analysis (DEA). This non-parametric linear programming technique considers both multiple in- and out- puts. Based on the concept of pareto efficiency, it computes an efficiency score where the associated weights of the inputs and outputs are determined endogenously. The DEA efficiency scores are then used as explanatory variables in panel data regressions of profitability. Our main finding is that the efficiency scores indeed contribute significantly to explaining profitability differences between firms, even after controlling for industry effects and unobserved systematic firm effects.     

Reactive transnationalism: homeland involvement in the face of discrimination

In this article we examine whether migrants' perceived discrimination in the country of settlement leads to an increase of their transnational involvement. So far, this so‐called ‘reactive transnationalism’ has not been studied extensively. Based on literature on discrimination and transnationalism, reactive transnationalism is expected to be most prominent among socioeconomically successful migrants, particularly among males and those who consider themselves Muslims. Our research among middle‐class migrants in Rotterdam, the Netherlands, indeed shows that the more respondents experienced discrimination, the more transnationally involved they are, both regarding transnational identifications and transnational activities. While no gender difference was found regarding reactive transnational activities, for women perceived discrimination proves to lead to stronger instead of weaker transnational identifications than for men. The fact that no difference was found between Muslim and non‐Muslim respondents regarding reactive transnationalism suggests that, despite heated public debates about ‘Islam’, in the Netherlands, ethnic divides – being considered as ‘Dutch’ or ‘non‐Dutch’ – are even more prominent than religious ones.     

DYNAMICS OF RETAIL ADVERTISING: EVIDENCE FROM A FIELD EXPERIMENT

We use a controlled field experiment to investigate the dynamic effects of retail advertising. The experimental design overcomes limitations hindering previous investigations of this issue. Our study uncovers dynamic advertising effects that have not been considered in previous literature. We find that current advertising does affect future sales, but surprisingly, the effect is not always positive; for the firm's best customers, the long-run outcome may be negative. This finding reflects two competing effects: brand switching and intertemporal substitution. We also find evidence of cross-channel substitution, with the firm's best customers switching demand to the ordering channel that corresponds to the advertising. ( JEL L2, L81, M3)
