The Circulation of Ideas in Firms and Markets

Novel early stage ideas face uncertainty on the expertise needed to elaborate them, which creates a need to circulate them widely to find a match. Yet as information is not excludable, shared ideas may be stolen, reducing incentives to innovate. Still, in idea-rich environments inventors may share them without contractual protection. Idea density is enhanced by firms ensuring rewards to inventors, while their legal boundaries limit idea leakage. As firms limit idea circulation, the innovative environment involves a symbiotic interaction: firms incubate ideas and allow employees to leave if they cannot find an internal fit; markets allow for wide circulation of ideas until matched and completed; under certain circumstances ideas may be even developed in both firms and markets.Ideas, Innovation, Entrepreneurship, Firm Organization, Start-Ups

Environmental Policy, Education and Growth with Finite Lifetime: the Role of Abatement Technology

This note shows that the assumptions about the abatement technology modify the impact of the environmental taxation (both the size and the “direction”) on the long-run growth driven by human capital accumulation à la Lucas (1988), when the source of pollution is private consumption and lifetime is finite. When the human capital’s share in the abatement services production is higher (respectively lower) than in the final output production, a higher environmental tax reduces (resp. increases) the allocation of human capital in production sectors (abatement service and final output) and boostes (resp. decreases) the BGP rate of growth. When abatement services are produced with the final output, the environmental taxation does not influence growth.Growth, Environment, Overlapping Generations, Human capital, Finite Lifetime, Abatement

The Paradox of New Members in the EU Council of Ministers: A Non-cooperative Bargaining Analysis

Power indices suggest that adding new members to a voting body may increase the power of an existing member, even if the number of votes of all existing members and the decision rule remain constant. This phenomenon is known as the paradox of new members. This paper uses the leading model of majoritarian bargaining and shows that the paradox is predicted in equilibrium for past EU enlargements. Furthermore, a majority of members would have been in favor of the 1981 enlargement even if members were bargaining over a fixed budget.Majoritarian Bargaining, Weighted Voting, Power Measures, EU Enlargement, Paradox of New Members

Resistance to Change

Established firms often fail to maintain leadership following disruptive market shifts. We argue that such firms are more prone to internal resistance. A radical adjustment of assets affects the distribution of employee rents, creating winners and losers. Losers resist large changes when strong customer goodwill cushions the consequences. Partial adaptation may lead winners to depart to form new firms with no goodwill, but no internal resistance.Resistance to Change, Leadership, Adaptation

Drought and Civil War in Sub-Saharan Africa

In this paper, we show that drought has a positive effect on the incidence of civil war over the 1945-2005 period in Sub-Saharan Africa. We use the Palmer Drought Severity Index which is a richer measurement of drought than the measures used in the literature (rainfall and temperature) as it measures the accumulation of water in the soil in taking into account the temperature and the geological characteristics of the soil. We show that the risk of civil war increases by more than 42% from a “normal” climate to an “extremely drought” climate. Surprisingly, only 2.5% of this effect is channeled through economic growth.Climate Change, Drought, Civil War

On the Optimal Taxation of Common-Pool Resources

Recent research developments in common-pool resource models emphasize the importance of links with ecological systems and the presence of non-linearities, thresholds and multiple steady states. In a recent paper Kossioris et al. (2008) develop a methodology for deriving feedback Nash equilibria for non-linear differential games and apply this methodology to a common-pool resource model of a lake where pollution corresponds to benefits and at the same time affects the ecosystem services. This paper studies the structure of optimal state- dependent taxes that steer the combined economic-ecological system towards the trajectory of optimal management, and provides an algorithm for calculating such taxes.Differential Games, non-linear Feedback Nash Equilibria, Ecosystems, Optimal State-dependent Tax

Liberalizing Climate-Friendly Goods and Technologies in the WTO: Product Coverage, Modalities, Challenges and the Way Forward

The Doha Round Agenda (paragraph 31(3)) mandates to liberalize environmental goods and services. This mandate offers a good opportunity to put climate-friendly goods and services on a fast track to liberalization. Agreement on this paragraph should represent one immediate contribution that the WTO can make to fight against climate change. This paper presents the key issues surrounding liberalized trade in climate-friendly goods and technologies in WTO environmental goods negotiations. It begins with what products to liberalize and how. Clearly, WTO environmental goods negotiations to date show that WTO member countries are divided by this key issue. Focusing on the issue, the paper explores options available to liberalize trade in climate-friendly goods and technologies, both within and outside the WTO, and along with these discussions, discusses how to serve the best interests of developing countries.Environmental Goods and Services, Low-Carbon Goods and Technologies, Doha Round, WTO
