Market dynamics with firm-specific fixed and variable
In this easy evolutionary model you'll find a
market with a large number of firms, each characterised by a different
cost structure, and you'll be able to study the evolution of profits
over time, according to changes in demand and endogenous technology
A key statement will relate the way demand interacts
with the kind of technological innovation
approved by top management.

retailing opportunities and threats using agent-based simulation
As a valuable supporting tool for the marketing
analysis of opportunities and threats on retail markets, an agent-based
simulator is proposed, providing insights to answer to questions
- What happens in the distribution landscape
if we open a new outlet? Where should it be located? What profile
(assortment composition, price levels, size) the new outlet should
- What if competitors open or close outlets? What should we then
change in the profile of our outlets?
- What if the purchasing behaviour of consumer households changes?
E.g. purchasing power and decision rules changes due to economic
- What if the cost structure changes? E.g. there is easy funding
of outlets in less-favoured areas by municipalities and regional
the poor pay more than the rich
This paper presents eleven groups of reasons
and conditions under which, painfully surprisingly, the poor has
to pay a higher price than the rich for the same good or for the
same fulfillment of a need. This is conducive to devise innovative
anti-poverty policies and business practices.

Is anything worth keeping in microeconomics?
A poignant critique of neoclassical microeconoimcs,

Addressing a missing element in the Toledo Declaration with industrial

landmark of urban regeneration policy for EU, the Toledo Declaration,
amidst the call for an integrated approach to address sustainability
challenges by the declaration, exhibits a predominant focus on using
local actions to solve local problems.
This lope-sided scope may give rise to policies that end up shifting
problems beyond the local jurisdiction. Some of these problems can
be deduced using key industrial ecology concepts, such as material
flow analysis and life cycle assessment.
The author, a Singaporean scholar, provides a few possible strategies
to cope with the issue, after a longitudinal study showing a specific

The impact of market structure and irreversibility
on investment under uncertainty: an empirical analysis
This paper estimates a model of investment
under product price uncertainty for 23 French industries during
the period 1977-1997 and represents the first empirical work that
includes variables of market structure (in terms of degree of competition)
in a model of investment under uncertainty.
In the paper, Sara
Maioli presents one of the very first attempts to make explicit
the empirical relationship between investment and uncertainty
under different degrees of irreversibility.

You are a monopolist
The traditional monopolist's choice about price and quantity is now
given a new dynamic setting where you can interact. Demand is unknown
and the produced good is durable across periods of time. Thus, sales
needn't be equal to production since inventories can pile up and go
down. A lot of strategic consequences arise, as you can discover playing
with the business game.

Outward foreign direct investment and technology transfer:
selected results from the U.S. and Taiwan in the electronics industry
Outward Foreign Direct Investment will be heavily criticized if
the outgoing investment appears to transfer or outsource jobs that
are seen as needed by the home country’s
workers, and if there is a perceived danger of allowing critical
technology to be dispersed. Any Inward FDI will be criticized if
it is seen as allowing foreign entities to own the engines of industry
and gain control of critical technology.
This paper focuses on the electronics industry
and presents some examples of countries’ policies concerning
technology transfers and the effects on industry of each of the
three reactions by policy makers and high-level managers.

Profits, competition and opportunity costs: two introductory
papers on the flaws in neoclassical approach
Prof. Kepa M. Ormazabal
points out at contradictions in neoclassical theory of firm where
two opposite notions of profits
are used together, making the maximization of profits irrational
if owners' revenue is considered as cost.
The definition of competitive profit as the opportunity cost of
capital is shown to involve a self-contradictory notion of opportunity
cost. The student will better follow this argument thanks to a constant
reference to Varian's standard texbook.

the employment effect of FDI inflows to Egypt: Does the mode of
entry matter? (2008)
Egypt has attempted to attract Foreign
Direct Investments since 1974 and has offered generous incentives
to achieve this target, motivated by low domestic savings
rates accompanied by inefficient financial intermediation and
the opportunity to benefit from the direct and indirect effects
of FDI on increasing demand for labour.
This is especially important given a chronic unemployment
problem that the Egyptian economy suffers from. This paper extensively
assess empirically the effect of FDI and argue about the importance
of studying FDI at the most disaggregated possible level, since
they are not homogeneous in their effects.

for the "national resource curse": should we distribute
oil revenues to the citizens directly instead that to governments?
Countries with an abundance of natural resources
have on average lower economic growth than resource-poor countries.
They also have more poverty and
are more likely to suffer from violent conflict. These negative
outcomes in resource-rich countries are called the ‘curse
of natural resources.’ Dr. Martin
E. Sandbu proposes a policy of revenue distributions from taxable
resources to individuals as a way of addressing the curse. Instead
of paying resource rents in to the government treasury, they would
be distributed equally to all indviduals, but the government would
then be allowed to tax it back.

of delayed feedback on learning, performance and strategy search
Economic agents live in an uncertain environment,
where they have to learn how to behave and which is the performance
of their actions. Strategy is not given: they have to search for
the "right one", if exists at all. Feedback
is a crucial mechanism linking the past with the future, possibly
helping the agents in their tasks. In particular, the timing
of feedback signals can deeply influence their effects.
Is immediate feedback always superior to delayed
feedback? Are the features of the environment irrelevant? This paper
offer original experimental results on the influence of delayed
feedback on learning, performance and strategy search.
decisions and pro-social behavior: a field experiment on blood donation
In this paper, Alois Stutzer, Lorenz Goette
and Michael Zehnder propose a decision framework where people are
individually asked to either actively consent or dissent to some
pro-social behavior. The authors hypothesize that confronting individuals
with the choice of engaging in a specific pro-social behavior contributes
to the formation of issue-specific altruistic preferences while
simultaneously involving a commitment. The hypothesis is tested
in a large-scale field experiment on blood donation. This "active-decision"
intervention substantially increases the stated willingness to donate
blood, as well as the actual donation behavior of people who have
not fully formed preferences beforehand.

symmetric integration is just the 6% of non-absent relationships.

which is so present in these countries. Unlike in rich countries
where informality is largely a result of the tax burden, the informal
economy in developing countries is largely a result of high fixed
costs of entry into the formal sector. The tax burden is lower
in developing countries and the barriers to entry into the formal
economy are higher. Empirical analysis supports the results of this
