Essay: Analysing 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 such as:

- 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 have?
- 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 crisis.
- What if the cost structure changes? E.g. there is easy funding of outlets in less-favoured areas by municipalities and regional authorities.

Is anything worth keeping in microeconomics?

Essay: European space and West-East flows of tourists The role of Italy

The broad concept of "trajectory" covers a crucial phenomenon in the contemporary reshaping of European space.

Published by the Polish Academy of Science, this short paper by Valentino Piana, underlines the meaning of tourism as a symptom of the emergence of new stronger trajectories, provides a quantitative analysis of data on West-East bilateral flows of tourists, supplies a longer discussion of the qualitative role of Italy in these flows and in their deeper meaning.

Essay: Addressing a missing element in the Toledo Declaration with industrial ecology (May 2011)

A 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 case.

Essay: Package size, price, and consumer rules

Optimal commercial offer by retailers depends not only on efficient logistics and buyer's power with respect to the supply chain: it hinges on the segmentation of customers according to their rules of choice.

Essay: Economic development from the perspective of evolutionary economic theory
 
Evolutionary theory sees the economy as always in the process of change that involves economic actors taking actions that break from previous behavior, and an environment in continuing flux because of the innovation.

While neoclassical theory sees the economy as at rest, or undergoing well anticipated change it has nothing to say about these kinds of conditions.

Therefore the author, Richard Nelson, believes the processes of economic catch-up have to proceed under the implicit or explicit guidance of an evolutionary economic theory.

Essay and Software : You are a monopolist

Essay: 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.

In the second paper, the neoclassical theory of competition is critically re-examined and compared to the solutions of classical theory.

Essay: Assessing 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.

Essay: The mystery of excess trade (balances)

Bilateral trade balances are an important source of frictions in international trade relations, so it is important to understand their provenance.

Both theories perform poorly in explaining bilateral trade balances. Actual bilateral trade balance are vastly larger than those predicted by the theory, a result that may be termed the "mystery of the excess trade balances".

Essay: A solution 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.

Essay: A new approach to business fluctuations: heterogeneous interacting agents, scaling laws and financial fragility

Business fluctuations in GDP, investment, etc. can be explained in a new micro-founded way. The authors present a simple agent-based model, whose core is the interaction of heterogeneous financially fragile firms and a banking sector. In their framework, the origin of business fluctuations can be traced back to the ever changing configuration of the network of heterogeneous interacting firms.

Simulations of the model replicate surprisingly well an impressive set of stylized facts, particularly two well known universal laws.

Essay: Influence of delayed feedback on learning, performance and strategy search - revisited

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.

Essay: Active 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.

Essay: Tax base in developing countries

How to increase the tax revenue in developing countries? By enlarging the tax base the fiscal burden would be better distributed, comprehending the large informal economy 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 paper by prof. Emmanuelle Auriol and Michael Warlters.
