This is admittedly a shameless attempt to increase my human capital — by promoting the paper with the title above. The paper is joint work with Eirik S. Knudsen, and it is recently out in SEJ.
Abstract: We examine how firms’ relative emphasis on exploration and exploitation influence their human capital responses to recessions. We hypothesize and find that the higher the focus on exploration, the more firms invest in training, the more likely they are to hire, and the more likely they are to lay off employees during a recession. Finally, we also find that exploration-oriented firms are more likely to combine the accumulation of human capital through training, with both hiring and firing. This indicates that firms focusing on exploration more actively pursue the opportunities created by increased labor market imperfections during recessions. These results contribute to the literature by highlighting how recessions affect firms’ flow of human capital investments, and subsequently stocks, depending on their strategic orientations.

I strongly think this paper is both timely and useful.

From Scott Masten we received this classic gem:
A growing interest in and concern about the adequacy and fairness of modern peer-review practices in publication and funding are apparent across a wide range of scientific disciplines. Although questions about reliability, accountability, reviewer bias, and competence have been raised, there has been very little direct research on these variables.
The present investigation was an attempt to study the peer-review process directly, in the natural setting of actual journal referee evaluations of submitted manuscripts. As test materials we selected 12 already published research articles by investigators from prestigious and highly productive American psychology departments, one article from each of 12 highly regarded and widely read American psychology journals with high rejection rates (80%) and nonblind refereeing practices.
With fictitious names and institutions substituted for the original ones (e.g., Tri-Valley Center for Human Potential), the altered manuscripts were formally resubmitted to the journals that had originally refereed and published them 18 to 32 months earlier. Of the sample of 38 editors and reviewers, only three (8%) detected the resubmissions. This result allowed nine of the 12 articles to continue through the review process to receive an actual evaluation: eight of the nine were rejected. Sixteen of the 18 referees (89%) recommended against publication and the editors concurred. The grounds for rejection were in many cases described as “serious methodological flaws.” A number of possible interpretations of these data are reviewed and evaluated.
Are these findings specific to the 80s and psychology? Care to replicate?

Underprovision of Public Registries?
Organizing registries is harder than it seems. Governments struggled for almost ten centuries to organize reliable registries that could make enabling rules safely applicable to real property. Similarly, company registries were adopted by most governments only in the nineteenth century, after the Industrial Revolution. Moreover, though most countries have now been running property and company registries for more than a century, only a few have succeeded in making them fully functional: in most countries, adding a mortgage guarantee to a loan does not significantly reduce its interest rate.
US registries show that these difficulties do not only affect developing countries. Many US registries are stunted, shaky institutions whose functions are partly provided by private palliatives. In land, the public county record offices have been unable to keep up with market demands for speed and uniform legal assurance. Palliative solutions such as title insurance duplicate costs only to provide incomplete in personam guarantees or even multiply costs, as Mortgage Electronic Registry Systems (MERS) did by being unable to safely and comprehensively record mortgage loan assignments. In company registries, their lack of ownership information means that they are of little help in fighting fraud, and their sparse legal review implies that US transactions require more extensive legal opinions. In patents, a speed-oriented US Patent and Trademark Office combines with a strongly motivated patent bar to cause an upsurge of litigation of arguably dangerous consequences for innovation.
The introduction of registries has often been protracted because part of the benefits of registering accrue to others. They also have to compete with private producers of palliative services (i.e., documentary formalization by lawyers and notaries) who usually prefer weak or dysfunctional registries, as they increase the demand for their services. Moreover, most legal resources, including the human capital of judges, scholars, and practitioners is adapted to personal instead of impersonal and registry-mediated exchange.
Information and communication technologies have opened new possibilities for impersonal trade, thus increasing the demand for the institutions, such as registries, that support impersonal trade. Economic development therefore hinges, more than ever, on governments’ ability to overcome these difficulties, which are allegedly holding back the effective registries needed to enable impersonal exchange and exhaust trade opportunities.
Arrunada Seminar: Corrado Malberti – What could be the next steps in the elaboration of a general theory of public registers?

What could be the next steps in the elaboration of a general theory of public registers?
From a lawyer’s perspective, one of the most important contributions of Arruñada’s Institutional Foundations of Impersonal Exchange is the creation of a general economic theory on public registers. Even if this work is principally focused on business registers and on registers concerning immovable property, many of the results professor Arruñada achieves could be easily extended to other registers already existing in many legal systems or at the transnational level.
For example, a first extension of the theories proposed by professor Arruñada could be made by examining the functioning of the registers that collect information on the status and capacity of persons. A second field that should probably benefit from professor Arruñada’s achievements is that of public registers that operate at a transnational level and established by international treaties. In particular, in this second case, the reference is obviously to the Cape Town convention on International Interests in Mobile Equipment which will, and — to some extent — already has, resulted in the creation of different registers for the registrations of security interests for Aircrafts, Railway Rolling Stock, and Space Assets. In my view it will be important to test in what measure the solutions adopted for these registers are consistent with the results of Arruñada’s analysis.

Will ICT Make Registries Irrelevant?
With this brief post, I would like to add some further discussion on the role of new technologies and ICTs for the evolution of registries. The book of Prof Arrunada touches upon the issue in chapter 7 where the role of technical chance is tackled. He discusses mainly the challenges in implementing different degrees of automation in pre-compiling and lodging information from interested parties and even in automating decision-making by the registry itself.
These challenges represent the costs of introducing ICTs in registries. In the book the benefits of ICTs for abating the costs of titling/recording are not discussed at length. Think of them in terms of the costs of gathering, entering, storing, organising and searching the data. I assume it is trivial to say that ICTs decrease the fixed and variable costs of registries even when some issues raised in the book are considered. In terms of the figure below (my elaboration of figure 5.1 on pg 133) this is equivalent to say that, thanks to ICTs, the black line representing the “Value of land under public titling” shifts upwards and therefore the “Indifference point for individual titling decisions” shifts leftward and makes registries more desirable.
However, i think that an important effect of ICTs is neglected in this analysis. In fact ICTs are now pervasive in most transactions. Land is observed with all sorts of satellite technology and the movement of objects and people is traced in many ways. Communications, both formal and informal are also traced and information on companies is just one click away for most individuals. I don’t want to discuss philosophical, sociological or legal aspects of this information bonanza. Neither neglect that more information doesn’t mean better or more trustworthy information. On the other I think we can agree that the quantity of information available to counterparts of a transaction is greatly increased and -more important- that verifiable evidence can be produced more easily should legal intervention in case of conflict arise.
All this information windfall may -this is my hypothesis- decrease the costs of keeping transactions out of registries and therefore improve the value of transactions under privacy. In terms of the figure below, this amounts to rotating the red line upwards and, as a result, shifting the “Indifference point for individual titling decisions” on the right.
In a sense, ICTs both i) decrease the costs of registries and ii) makes registries less relevant. On balance, it is hard for me to say which effect of ICTs may prevail. I think however this could be a very interesting empirical question to research.

I recently attended a presentation by the great social scientist Jon Elster, in which he lamented the state of affairs in social science. Elster has – quite nicely, IMHO – coined the terms hard and soft obscurantism as the main problems. To Elster, obscurantism generally refers to endeavors that are unlikely to produce anything of value, and where this can be predicted in advance. This in contrast to more honorable failures, where a plausible hypothesis turns out to be wrong, leaving much effort without much value.
Soft obscurantism is exactly what it sounds like. Unfalsifiable, impenetrable theories which often proudly ignores standards for argument and evidence that elsewhere constitute the hallmark of the scientific method. Examples are post modernism (Latour), structuralism (Lévi-Strauss), Functionalism (Bourdieu, Foucault), Marxism (Badiou) and psychoanalysis.
But there is a ditch on the other side of the road too. Hard obscurantism refers to mathematical exercises without any tangent to reality, which is useful neither as mathematics nor social science. Another form of hard obscurantism is data mining, or misuse of fancy econometrics, or a combination of the two. Both mathematical games and econometric voodoo give the appearance of “scientificness”, but Elster doesn’t hold his guns about the value created by hard obscurantism either:
“I believe that much work in economics and political science that is inspired by rational-choice theory is devoid of any explanatory, aesthetic or mathematical interest, which means that it has no value at all”
One can of course argue about the size of the size of the total problem, and relative size of each type (personally, I would bet on soft obscurantism as the bigger problem), but the key question is perhaps why obscurantism of either type isn’t gradually rooted out. According to Elster their combined “market share” in the social sciences seems to be growing.
