Parenthood and productivity of highly skilled labor: evidence from the groves of academe
We examine the effect of pregnancy and parenthood on the research productivity of academic economists. Combining the survey responses of nearly 10,000 economists with their publication records as documented in their RePEc accounts, we do not find that motherhood is associated with low research productivity. Nor do we find a statistically significant unconditional effect of a first child on research productivity. Conditional difference-in-differences estimates, however, suggest that the effect of parenthood on research productivity is negative for unmarried women and positive for untenured ...

On the Need for a Replication Journal
There is very little replication of research in economics, particularly compared with other sciences. This paper argues that there is a dire need for studies that replicate research, that their scarcity is due to poor or negative rewards for replicators, and that this could be improved with a journal that exclusively publishes replication studies. I then discuss how such a journal could be organized, in particular in the face of some negative rewards some replication studies may elicit.

Author identification in economics, ... and beyond
Identifying authorship correctly and efficiently is a difficult problem when the literature is abundant, but poorly recorded. Homonyms are tedious to differentiate. This paper describes how the field of economics has organized itself with respect to author identification. We describe the RePEc project with a special emphasis on the RePEc Author Service. We then discuss how the concept is currently being expanded to the entire scientific body with the AuthorClaim project.

Paving the Road for Replications: Experimental Results from an Online Research Bibliography
Are users of a bibliographic database interested in learning about replications? Can they be induced to learn? To answer these questions, we performed an experiment at the online research bibliography, RePEc (Research Papers in Economics). RePEc is the main research bibliography for pre-prints and published papers in economics. Using randomized stratification, we allocated 324 replications and their corresponding original studies to clusters. We then drew from those clusters to construct treatment and control groups. Brightly colored tabs were added to the relevant webpages to alert visitors ...

Universal Basic Income versus Unemployment Insurance
In this paper we compare the welfare effects of unemployment insurance (UI) with an universal basic income (UBI) system in an economy with idiosyncratic shocks to employment. Both policies provide a safety net in the face of idiosyncratic shocks. While the unemployment insurance program should do a better job at protecting the unemployed, it suffers from moral hazard and substantial monitoring costs, which may threaten its usefulness. The universal basic income, which is simpler to manage and immune to moral hazard, may represent an interesting alternative in this context. We work within a ...

Paving the Road for Replications: Experimental Results from an Online Research Repository
Are users of a bibliographic database interested in learning about replications? Can we motivate them to learn? To answer these questions, we performed an experiment on a RePEc (Research Papers in Economics) website: Using randomized stratification, we allocated 324 replications and their corresponding original studies to clusters; we then drew from those clusters to select treatment and control groups. We added brightly colored tabs to the relevant webpages to alert visitors to the existence of a replication study or to the original study of a replication. We monitored traffic over three ...

The Experience of the RePEc Plagiarism Committee in Economics
RePEc is an open bibliography project driven entirely by volunteers and without a budget. It was created to enhance the dissemination of research in economics by making it more accessible to authors, publishers, and readers: 1800 publishers participate in this initiative, and 44000 authors are registered. Some of those authors became frustrated when their work was plagiarized and no action was taken. Many have asked whether RePEc could take action. The RePEc Plagiarism Committee was created to respond to this request. Because RePEc has no enforcement power, it can only ?name and shame? ...

Academic rankings with RePEc
This document describes the data collection and use of data for the computation of rankings within RePEc (Research Papers in Economics). This encompasses the determination of impact factors for journals and working paper series, as well as the ranking of authors, institutions, and geographic regions. The various ranking methods are also compared, using a snapshot of the data.

Basel Accord and financial intermediation: the impact of policy
This paper studies loan activity in a context where banks must follow Basel Accord-type rules and acquire financing from households. Loan activity typically decreases when entrepreneurs? investment returns decline, and we study which type of policy could revigorate an economy in a trough. We find that active monetary policy increases loan volume even when the economy is in good shape; introducing active capital requirement policy can be effective as well if it implies tightening of regulation in bad times. This is performed with an heterogeneous agent economy with occupational choice, ...
