The competitiveness of firms in open
economies is increasingly determined by access to low-cost
and high-quality producer services - telecommunications,
transport and distribution services, financial
intermediation, etc. This paper discusses the role of
services in economic growth, focusing in particular on
channels through which openness to trade in services may
increase productivity at the level of the economy as a

The policy reforms called for in the
transition from a socialist command economy to a developing
market economy bring both opportunities and risks to a
country's citizens. In poor economies, the initial
focus of reform efforts is naturally the rural sector, which
is where one finds the bulk of the population and almost all
the poor. Economic development will typically entail moving
many rural households out of farming into more remunerative

Mozambique, the only Lusophone country covered in the agribusiness indicators initiative, has had a turbulent history since independence. Civil unrest over some 20 years and frequent drought in southern Mozambique, coupled with floods near the many waterways that transect the country (mainly east-west), have inhibited an agricultural transformation. Even so, Mozambique could be a regional breadbasket. The country has much potentially usable arable land, along with access to river water for irrigation in many agricultural production zones, particularly in central and northern Mozambique.

Nearly 200 million Africans currently live in slums.

This volume is organized as follows.
Chapter one address two questions: how has spatial
concentration evolved with growth and development, and what
are the efficiency implications of too much or too little
spatial concentration? This chapter summarizes the various
models that analyze growth by geographic concentration and
sets the foundation for concepts discussed in later
chapters. Chapter two focuses on urbanization in

Poor people living in slums are at
particularly high risk from the impacts of climate change
and natural hazards. They live on the most vulnerable land
within cities, typically areas deemed undesirable by others
and thus affordable. This study analyzes the key challenges
facing the urban poor, given the risks associated with
climate change and disasters, particularly with regard to
the delivery of basic services, and identifies strategies

This paper summarizes the policy-relevant insights of a generation of research on scale economies. Scale economies in production are of three types: internal economies associated with large plants, localization economies that come from sharing of inputs and infrastructure and from greater competition among firms, and urbanization economies that are generated through diversity and knowledge spillovers. The benefits (and costs) of localization and urbanization are together called “external (dis) economies” because they arise due to factors outside any single household, farm or firm.
