The literature shows that the impact of migration on welfare in the receiving and sending
countries depends heavily on the flexibility of labour markets. The labour market impact of
migration has been examined in a large number of econometric studies in Europe. These
studies rely on a cross-section of either regions or branches, and use variations in the
migrant density in order to identify the impact of migration on wages and employment. The
results of these studies show that migration is neutral for wages and employment of natives
in the receiving countries (see for details Longhi et al., 2005, 2007).On the other hand, as many studies show, migration provides many benefits and
contributes to economic growth and the creation of new jobs. Economic growth and the
creation of new jobs are strongly associated with the willingness to take up chances across
regions and the supply of jobs regulates the flow of people seeking work. Regional labour
mobility in the EU-15 is low only about 1 out of 200 workers chang
, 2005). Hence, immigration from outside the European Unionhas become a potentially very crucial role for the creation of a higher level of labour
mobility in Europe. If there is labour mobility, it is largely due to international migration
(Zimmermann, 2005). Europe is a place where migration is especially useful from an
economic perspective. In the context of (2005) shows that international migration can significantly increase income per capita in
Europe. They have estimated that at the given wage and productivity gap between Western
and Eastern Europe, migration of 3% of the Eastern population to the West could increase
total EU GDP by up to 0.5%. The contributions of migrants to the economic growth as well
as to the creation of new jobs will be further examined in the next section.

has only a marginal impact on wages and employment of natives in the receiving countries

It is noteworthy that many studies also show that migration provides many benefits and
contributes to economic growth and the creation of new jobs. Economic growth and the
creation of new jobs are strongly associated with the willingness to take-up chances across

In addition, greater labour mobility helps to facilitate trade and increases the cross-border
demand for domestic output. The nurturing of cultural diversity may further enhance
trade. However, social cohesion and the accumulation of social capital are not natural
outcomes in increasingly diverse societies, but require resources to be allocated to thepromotion of desirable social outcomes. Thus, the social evaluation of greater cross-border
mobility resulting from greater international economic integration must go hand in hand
with the economic assessment.

Rietveld.

Voorbeeld hoofdstuk vijf, dat Steenbruggen en Nijkamp in 2012 publiceerden in Transport
Policy. Dit bevat diverse tekstblokken uit een artikel dat Nijkamp in 2012 in zijn eentje ook

Tekstblok uit hoofdstuk vijf, p. 111/112:The history of quantitative data analysis in transport geography now already spans several
decades. In the 1980s, the need for a more appropriate behavioural underpinning of spatial
interaction models led to the emergence and popularity of discrete utility (or choice)
models, in particular multinomial logit and probit models, later on followed by conjoint
analysis modelling. Such individually-based models were proven to be consistent with
aggregate-oriented spatial interaction models, and were widely accepted in the transport
research community. They also turned out to be eminently suitable for actor-based policy
simulation experiments, for instance, in the context of micro-simulation models and agent-
based models.
All such models were widely used for prediction purposes, evaluation experiments and
policy analyses in the planning and transportation science field: for example, to trace thesystem-wide effects of road pricing on the behaviour of car drivers. With the advent and
introduction of ICT (Information and Communication Technology), the computing capacity
in quantitative research showed a dramatic increase, so that spatial dynamics could also be
captured in a statistically more satisfactory way. In recent years, complexity theory has
made a remarkable contribution to a better understanding of the sensitivity of spatial
systems evolution to endogenous non-linear space-time behaviour. Space-time dynamics
(e.g. in the cellular automata domain) became an important ingredient of advanced
transportation research and spatial analysis, and prompted a new departure, viz. the use of
data mining methods for large data sets. The current use of computational neural networks
and genetic algorithms demonstrates convincingly the great potential of more sophisticated
data collectio q 97 (all things in space are related to each other, but nearby things are more related than distant
things), was taken up in a new strand of the literature addressing spatial - and spatio-
temporal - autocorrelation, either as testing devices or as design mechanisms for spatial
(dynamic) models (see also Tobler, 2004). Cellular automata, spatial filtering techniques,
and self-z K interaction analysiswere a logical follow-up and complement to the above-mentioned trends (see, e.g., Codd,

al., 2010).
In recent years, we have witnessed the increasing popularity of Location-Based Services
(LBS) and data using various kinds of electronic identification systems, so that at an
individual level (a traveller, a container, a truck, or a taxi) the geographical position of a unit
can be traced with great precision. Many applications are available both for purchase andfor
Mobilephonedatatosupporttrafficincidentmanagement free to cell phone and other wireless
device users. For example, Japanese parents are using location-based tracking devices to
monitor the spatial movement of their children. This new approach will certainly generate
many new applications in space-time geography.
An interesting source of individually-based information on the space-time position and
behaviour of persons is in principle available from mobile (or cell) phone data derived from
the GSM network. The penetration rate of mobile phones is rapidly reaching a saturation
point in most OECD14 countries, so that a system-wide coverage does in principle exist,
almost in continuous space-time format. Such data - as very accurate representations of the
individual space-time location - are in principle available from telephone operators. If suchdata - in anonymous form - could be made available to the research community, an
unprecedented source of information on the space-time geography of individuals could be
used in applied research (for an overview, see Steenbruggen et al., 2011).
It is noteworthy that this idea of a continuous space-time map at an individual scale was
already put fo 1967. He
- -space model to provide a
description of both individual space-time patterns and the resulting spatial interactions, if
many indi universal limited supply of daily time resources. His work was regarded as a new
perspective in social- behavioural geography, as it highlighted so clearly the essence of
interaction and congestion phenomena in space (see Pred, 1977). Three constraints appear
to act on the daily mobility pattern of individuals, viz. capability constraints, coupling
constraints, and authority constraints. He also laid the foundation for activity-based
transport geography, but, unfortunately, lack of data and the technology available to
implement this framework often precluded a full operational application of his path-
breaking ideas. Now with the potential availability of large-scale continuous space-time
information databases on the spatial movements of individuals, a really interesting novel
approach might be developed, which could have great implications for spatial modelling.
Two such approaches can be found in the literature. The first incorporates elements of
Gibson (1979). Cognitive constraints, e.g. choice behaviour, were not given explicit
attention in the original time-geography framework. These constraints can help personalize
LBS, providing the possibility to collect more detailed information about the choices
individuals make. The second approach adjusts the space-time prism concept to support
interactions and activities between physical and virtual spaces (Yu and Shaw, 2008). This
approach would help to model and understand how, in the age of mobile computing where
a variety of activities and services can be carried out on the go, individuals are allocating
their space and time resources.

contributions on entrepreneurship offered by Cantillon, Say, Marshall, Schumpeter, Knight
and Kirzner, respectively.
The pioneering study of Cantillon (193 1) on the role of entrepreneurship made a main
distinction between the following economic agents: (i) land owners who were financially
independent, (ii) who were involved in risk- taking activitieswith a view to profit-making, and (iii) who were ensured of a fairly stable income
by means of a labour contract. In Cantillons view, the market economy was a self-
regulating network of reciprocal exchange arrangementswhich were able to produce
equilibrium prices through free entry and exit of business firms. In Cantillons perception
of entrepreneurship, the mediating role of the economic actor, who needs to anticipate
uncertain future events and to see uncertainty as an economic opportunity, is more
important than his innovative attitude. The survival of the fittestwould be best
guaranteed by those entrepreneurs who know how to handle risk situations properly.

In the last decade, a number of empirical studies have suggested that differences between
the genders in managerial performance can be explained by cultural factors, such as
nationality. Managerial performance has been found to differ across nationalities, both in
terms of perceptions of what determines managerial performance, and in terms ofmanagement practices (Atuahene-Gima and Ko, 2001; Neelankavil et al., 2000; Steensma et
al., 2000).
The existing literature has revealed positive relationships between managerial functions
related to innovation, business longevity (Gagnon et al., 2000) and turnover from sales
(Chakrabarti, 1990; Deeds and Rothaermel, 2003); and that a greater focus on leading
change (Chakrabarti, 1990; Deeds and Rothaermel, 2003) has also stimulated business
turnover from sales.

Shelter role
The city is offering settlement facilities for numerous people, based on its scale advantagesin housing many citizens. Shelter has even become a human right, and cities are able to care
for the housing needs of people. From this perspective, cities offer a significant contribution
to a sustainable human habitat.
Religious role
In the early biblical history the city was often regarded as the source of evil (Babylon,
Nineveh). But in the later history we observe a more positive appreciation of the city.
Jerusalem was the seat of King David and the New Jerusalem became even a metaphor for a
total re-birth of mankind.
Cultural role
Historically, the city was the place where arts and sciences were flourishing. Venice,
Bologna, Padua, Paris, Augsburg, Amsterdam and many other places offer an overwhelmingPeter Nijkamp, Regional Science Inquiry Journal, Vol. III, (1), 2011, pp13-22 15
evidence of the favourable seedbed conditions of an urban way of life for the advancement
of culture.
Political role
Democracy was a new type of governance which found its seedbed in the city. And still
nowadays political power is largely concentrated in cities and governments have
established their premises in cities. De-concentration of physical government facilities (e.g.,
premises) has never become very successful. Administrative functions are usually executed
in capital cities of countries, or at least in cities with a critical political mass.
Economic role
The city is the market place for economic activity. It is also the place where usually productsare designed and often manufactured. Furthermore, it is a marketplace where capital is
supplied and advisory services are offered. In addition, the city is - as a result of various
types of agglomeration advantages - a very efficient way of organizing production and
