When Galbraith Frightened Conservatives: Power in Economics,Economists’ Power,and Scientificity

In this article, I first expound John Kenneth Galbraith’s general theory of power. Galbraith always took into account phenomena of power in economics, and shed light on the power of economists in particular. I then show how the reaction of conservatives to the broadcasting of the Age of Uncertainty highlights the relevance of Galbraith’s theory. Letters exchanged by conservative Lords in an effort to fight against Galbraith’s ideas paradoxically illustrate his theory. This leads to questions about the status of economists, popularizers, and experts. Finally, I argue that convictions have a crucial role in scientific production, and that Robert Solow’s distinction between the “serious scholars” and the proselyte economist is irrelevant because of its incapacity to understand how economists produce knowledge.     

Strategic automation and decision-making authority

This paper studies how automation impacts the structure of decision-making in organizations. We develop a theoretical model of a firm, where a principal makes a decision about how much to prioritize the new product development division when the division is led by a manager who holds private information specific to this division and has misaligned preferences with the principal. The principal chooses whether to decentralize this decision by delegating it to the manager, resulting in more informed but unbiased decision. In this setting, we investigate how automation which reduces operational variability may alter this choice of organizational structure. The findings from our analysis show that firms deploy automation resources differently depending on their organizational structure: centralized firms choose to automate divisions that face more uncertainty, while decentralized firms do the opposite. Moreover, increasing access to automation results in higher centralization of decision-making in firms. In the extensions, we show that the strategic use of automation reduces the informativeness of intrafirm communication, and also, that automation can be a strategic substitute to monetary contracts.     

The Effect of the Arab Spring on Preferences for Redistribution in Egypt

This paper investigates the effect of the revolution that occurred in January 2011 in Egypt on the demand for redistribution in that country, which has drastically increased since that period. This shock has been an important event, enhancing freedom and the political structure. In a first step, taking into account the main determinants of preferences for redistribution in the literature, our results differ, showing a positive impact of religion and a negative impact of altruistic attitudes. In a second step, we rely on a diff-in-diff approach to estimate the effect of the revolution, using three similar countries as a control group. We find that Egyptians became much more favorable to redistribution after the Arab Spring. Moreover, the revolution effect is stronger for the poorest people and those who are interested in politics.     

Modeling Distribution Services and Assessing Their Welfare Effects in a General Equilibrium Framework

Most international trade models fail to account for the fact that almost all goods must pass through the distribution sector. The authors compare different approaches to modeling distribution within an Applied General Equilibrium framework and find that such modeling may significantly affect trade opening simulations. They also predict large potential gains from streamlining distribution. For instance, a 10% reduction in Japan's final goods distribution margins would benefit it as much as worldwide free trade would. They also find that, compared to trade opening, reducing margins leads to smaller inter‐sectoral production shifts and thus may engender less political opposition.     

Does legal system matter for directed technical change? Evidence from the auto industry

Does the effect of fuel taxes on clean innovations (e.g. hybrid technology) depend on the legal system’s rigidity? Using 1986–2005 data from more than 1900 firms, evidence suggests that auto-industry firms located in civil law (with more rigid laws) countries increase clean technology patenting more than common law (with more flexible laws) firms when the tax-inclusive fuel price rises. A rigid legal system appears to raise clean technology innovation.     

Agent-Based Facilitation of Water Allocation: Case Study in the Drome River Valley

The purpose of the 1992 French Water Act is to encourage negotiation and dialogue among local stakeholders within a framework which is very similar to a patrimonial approach. Potential use of models in such post-normal approaches is analyzed. Two kinds of models are compared: one is agent-based, the other follows a more classical approach. They are compared according to their contributions as negotiation support tools. This comparison is based on a specific collective decision process dealing with water allocation at the sub-basin scale, in which authors are involved. Both are used to support collective decision processes through simulation of resource use dynamics. Agent-Based Models entail the broadening of spatial information of actors in the process, revealing inter-connected topics not taken into consideration earlier. This makes it possible to remain relevant, despite the sometimes rapidly evolving stakes. The central point of this paper is the implementation, within a practical application, of theories advocating the use of ABM as a collective decision support system. This application promotes a better understanding of the kind of support ABM provides and the way it does so. This is brought about more by re-framing the discussion and modifying the representation of the system on the part of the stakeholders than by providing specific agreements.     

On the European Responsibility in the Agricultural Multilateral Trade Negotiations: Modelling the Impacts of the Common Agricultural Policy

The present round of multilateral trade negotiations is still deadlocked over agricultural trade. The European Union (EU) is urged by its trading partners to open its agricultural markets. Economic evaluations of trade liberalisation scenarios unanimously conclude that a substantial opening of agricultural markets is required for a successful (welfare‐improving) Doha Round. In this paper, we perform new evaluations to identify precisely the contributions of the European farm policy and to examine the robustness of these evaluations in the representation of this complex policy. Using the same specifications as in major previous studies, our first simulations show that the EU has a major responsibility in delivering significant gains to the developing countries. On the other hand, when we conduct the same experiments with a more relevant calibration and modelling of the European farm policy instruments, the gains that these developing countries may reap from the EU liberalisation are considerably reduced. Accordingly the current charge against the EU is simply inopportune.     

Identifying small mean-reverting portfolios

Given multivariate time series, we study the problem of forming portfolios with maximum mean reversion while constraining the number of assets in these portfolios. We show that it can be formulated as a sparse canonical correlation analysis and study various algorithms to solve the corresponding sparse generalized eigenvalue problems. After discussing penalized parameter estimation procedures, we study the sparsity versus predictability trade-off and the significance of predictability in various markets.
