The pricing kernel puzzle: survey and outlook

It has been a while since the literature on the pricing kernel puzzle was summarized in Jackwerth (Option-implied risk-neutral distributions and risk-aversion, The Research Foundation of AIMR, Charlotteville, 2004). That older survey also covered the topic of risk-neutral distributions, which was itself already surveyed in Jackwerth (J Deriv 2:66–82, 1999). Much has happened in those years and estimation of risk-neutral distributions has moved from new and exciting in the last half of the 1990s to becoming a well-understood technology. Thus, the present survey will focus on the pricing kernel puzzle, which was first discussed around 2000. We document the pricing kernel puzzle in several markets and present the latest evidence concerning its (non-)existence. Econometric studies are detailed which test for the pricing kernel puzzle. The present work adds much breadth in terms of economic explanations of the puzzle. New challenges for the field are described in the process.     

Integrating Consumer Rights into Copyright Law: From a European Perspective

Until recently consumers and consumer-interests have been virtually absent not only from the rules of copyright but also from copyright’s discourse. This has been so even though the combination of an expansion of copyright and a devaluation of the internal balancing mechanisms raise concern from a consumer perspective. There would, therefore, seem to be a need to incorporate a consumer perspective into copyright analysis. To integrate consumer interests in copyright law, this study recommends action aimed at two levels. On the general level it is suggested to rebalance copyright in order to recognize the interests of users on the same level as right holders. On the concrete level it is suggested to change the limitations found in copyright to ease access to reuse elements of previous works. It is also proposed to reinforce the rule on private copying and to consider measures to secure access to basic information.

Interconnection and competition among asymmetric networks in the Internet backbone market

We examine the interrelation between interconnection and competition in the Internet backbone market. Networks that are asymmetric in size choose among different interconnection regimes and compete for end-users. We show that a direct interconnection regime, peering, softens competition as compared to indirect interconnection since asymmetries become less influential when networks peer. If interconnection fees are paid, the smaller network pays the larger one. Sufficiently symmetric networks enter a Peering agreement while others use an intermediary network for exchanging traffic. This is in line with considerations of a non-US policy maker. In contrast, US policy makers prefer that relatively asymmetric networks peer.     

Long-run selection and the work ethic

That individuals contribute in social dilemma interactions even when contributing is costly is a well-established observation in the experimental literature. Since a contributor is always strictly worse off than a non-contributor the question is raised if an intrinsic motivation to contribute can survive in an evolutionary setting. Applying stochastic evolutionary dynamics we give conditions for equilibria with a positive number of contributors to be selected in the long run.     

The foundations of constitutionalism: an analysis of debaathification

This article analyzes the administration of lustration—what Arthur Stinchcombe termed the “social basis of constitutionalism”—and its unintended consequences in comparative and international law and politics. It is concerned with the social function of animating ideas in the evolution of institutions. The article demonstrates that in the case of Iraq, the commitment of institutional engineers and transitional administrators to the idea of purifying the state, and their concomitant willingness to watch the institution of lustration naturally evolve in respect of that central idea, has had disastrous consequences for the foundations of constitutionalism. These consequences flowed from the institutional design of the U.S. occupation more generally. By reconstructing, for the very first time, the evolution of debaathification in contemporary Iraq, this article deepens our understanding of the foundations of constitutionalism. Aside from its contribution to the theory of institutional design, the article also speaks to the ongoing debate over the creation of governments, regimes, and states in the international system. In the context of this debate, which has important implications for the practice of institutional design, the administration of lustration—from within or from without—is an insufficiently understood phenomenon, making it a worthy subject for institutional analysis.

The Dilemmas of Tax Coordination in the Enlarged European Union

This study evaluates the economic effects of corporate tax coordinationin the enlarged European Union (EU) using a computable generalequilibrium model. Our main findings are as follows: (i) Corporatetax coordination can yield modest aggregate welfare gains. The2004 enlargement of the EU has increased the potential gainsfrom tax harmonization, provided corporate tax rates and taxbases are harmonized at their unweighted averages. (ii) Allscenarios for coordination leave some EU Member States as winnersand others as losers. An agreement on tax coordination is thereforelikely to require elaborate compensation mechanisms. (iii) Thelarge and diverse country effects suggest that Enhanced Cooperationfor a subset of the Member States may be the most likely routetowards tax coordination. (iv) Identifying winners and losersfrom coordination for the purpose of a compensation mechanismmay be problematic, since countries experiencing gains in GDPand welfare tend to lose tax revenues, and vice versa.

Economic versus environmental improvement potentials of Danish pig farms

This article demonstrates how economic and environmental improvement potentials of Danish pig farms can be estimated using Data envelopment analysis (DEA). To avoid some of the problems associated with the definition of undesirable outputs, environmental variables are included as nutrients applied with manure and nutrients removed with the crops. These environmental variables are combined with a series of economic variables, including the costs of fertilizer. Furthermore, subvector efficiency and a two‐step analysis are used in order to consider economic and environmental (technical) efficiency separately. The empirical results show considerable improvement potentials, especially on the environmental variables. Sensitivity studies validate that these results are robust to possible uncertainties in the measurement of the environmental variables.
