Social capital and social learning after Hurricane Sandy

The post-disaster context is one characterized by profound uncertainty. Those affected by the storm, or earthquake, or flood, must determine what strategies to pursue in response to the disaster and must find ways to coordinate their recovery efforts with others in their community. Ex ante it is not clear what strategies will be most effective. If communities are to recover after a disaster, community members must engender and engage in a process of social learning involving experimentation, communication, and imitation. This paper explores the post-disaster social learning process. Specifically, we focus on the importance of social capital in facilitating social learning after a disaster, including facilitating community members’ ability to communicate their desire to return, to assess damage, to overcome barriers to rebuilding through collective yet voluntary action, and to learn from and imitate others’ successes. Focusing on how this process took place after Hurricane Sandy in Rockaway, New York, especially within the Orthodox Jewish community, we examine how community groups (a) adapted existing organization structures and (b) created new procedures and imitated the successful actions of others in order to spur recovery.     

With or Without U? The Appropriate Test for a U‐Shaped Relationship*

Nonlinear relationships are common in economic theory, and such relationships are also frequently tested empirically. We argue that the usual test of nonlinear relationships is flawed and derive the appropriate test for a U‐shaped relationship. Our test gives the exact necessary and sufficient conditions for the test of a U shape in finite samples in a large class of models.     

The “hidden catch” in <Emphasis Type="Italic">The Invisible Hook</Emphasis>

In The Invisible Hook, Leeson argues that by devising a complex system of rules (called the “pirate code”) and procedures for electing their leaders, pirate societies created governance structures where the leaders were strong enough to “control the governed” but were not strong enough to break the constraints that bound them. There is, however, a “hidden catch” within The Invisible Hook. There are important differences between pirate crews and societies, between pirate captains and political leaders, and between the pirate code and constitutions. Moreover, understanding these differences is critical for understanding how criminal bands were able to accomplish a feat that still proves problematic for many societies.     

Addiction – and rational choice theory

Becker and Murphy's theory is a well‐known contribution to economists on the discussion of addiction. This class of rational choice theory is still the most important reference for economists studying addiction. In this paper, the model and the economist's rational choice theory were challenged by modern neurobiological theory. The paper suggested reconstruction work of the standard inter‐temporal choice model along four lines to reduce the gap between the theory and the clinical definition of addiction: (1) a discount rate that varies; (2) revision of the concept consumption capital; (3) the possibility for genetic predisposition to addiction (even if the research up to now has not identified such a gene); and (4) social mechanisms that influence our behaviour.     

Ludwig Lachmann’s peculiar status within Austrian economics

Lachmann occupies a strange position within modern Austrian economics. He is viewed as something of an outsider and his views are often regarded as outside the mainline of modern Austrian thought. But, on several key issues – especially subjectivism and institutions – Lachmann’s positions are the dominant positions within the school. This article argues that, with little fanfare but in several important respects, Austrian economics has moved in a decidedly Lachmannian direction.

     

The capacity for self-governance and post-disaster resiliency

A community’s capacity for self-governance depends on the social coordination capacity of community organizations and associations, the ability of community members to effectively access both bonding and bridging social capital, the ability of community members to leverage their shared histories and perspectives, and the stability of social networks within the community. Both Elinor Ostrom and Jane Jacobs have explored how a community’s capacity for self-governance affects its ability to solve complex problems (for example, dealing with crime, the provision of public goods, or problems of neighborhood blight). The greater a community’s capacity for self-governance the better able it is to deal with these complex challenges. This paper examines how pre-disaster systems of self-governance aid in post-disaster community recovery. Our analysis focuses on the Mary Queen of Vietnam (MQVN) community and Gentilly, examines the effectiveness of their systems of self-governance prior to Hurricane Katrina and explores the role these systems played in promoting community recovery after the disaster.     

Emissions Trading with Updated Allocation: Effects on Entry/Exit and Distribution

Allocation of emissions allowances may have significant distributional and efficiency effects. It is well known that cost-efficiency may be achieved if allowances are auctioned or distributed in a lump sum manner, e.g., based on emissions levels before the start of the system (‘grandfathering’). Böhringer and Lange (Eur Econ Rev 49:2041–2055, 2005) show that a cost-effective outcome can also be achieved if the base year for allocation is continually updated (‘updating’), given that banking and borrowing are prohibited. In this paper we examine whether updating alters the entry and exit conditions for firms compared to grandfathering, and how it affects profits for new and existing firms. We find that the two schemes function surprisingly similar: First, the incentives to entry and exit are identical. Second, the total value of free quotas to existing firms, based on emissions before the system starts, is also identical without any auctioning. With updating initial claims for free allowances have a shorter lifetime compared to grandfathering, but quota prices are higher as firms anticipate the effect of current emissions on future claims to free allowances. The two effects exactly cancel each other out. If there is some combination of auction and free allocation, the total value of free quotas will always be highest under grandfathering if the auction rate is the same. Entry and exit incentives are still equal.     

Communicative action and the radical constitution: the Habermasian challenge to Hayek, Mises and their descendents

This paper evaluates Jurgen Habermas's typology of action andhis recent call for a radically democratic rule of law. Thetheory of action that Habermas develops, however, differs significantlyfrom the science of action (praxeology) of the Austrian school.As such, it represents a methodological challenge to Austrianpraxeology. Additionally, Habermas's criticism of the welfarestate is shown to be somewhat consistent with Hayek's criticisms,but his alternative to the welfare state challenges the politicalvision of many Austrian economists. This paper attempts to demonstratethat both Habermas's and the Austrian school's efforts sufferfrom similar weaknesses and epistemological pretences.     

On the Geometry of the Instrumental Variable Estimator*

I derive the exact distribution of the exact determined instrumental variable estimator using a geometric approach. The approach provides a decomposition of the exact estimator. The results show that by geometric reasoning one may efficiently derive the distribution of the estimation error. The often striking non‐normal shape of the instrumental variable estimator, in the case of weak instruments and small samples, follows intuitively by the geometry of the problem. The method allows for intuitive interpretations of how the shape of the distribution is determined by instrument quality and endogeneity. The approach can also be used when deriving the exact distribution of any ratio of stochastic variables.
