(Un)available upon request: field experiment on researchers' willingness to share supplementary materials

This article reports results of a field experiment in which two hundred e-mails were sent to authors of recent articles in economics that had promised to send the interested reader supplementary material, such as alternative econometric specifications, "upon request." The e-mails were sent either by a researcher affiliated at Columbia University, New York or the University of Warsaw, Poland; furthermore, the authors' position (assistant professor) was specified in half the e-mails only. Overall, 64% of the approached authors responded to our message, of which two thirds (44% of the entire sample) delivered the requested materials. The frequency and speed of responding and delivering were very weakly affected by the position and affiliation of the sender. Gender or affiliation of the author, number of citations or journal impact factor or the type of object in question seemed to make no difference. However, authors of published articles were much more likely to share than authors of working papers.     

Cracking the Code: Race,Class, and Access to Nightclubs in Urban America

Using ethnographic data collected in the downtown nightlife of Athens, Georgia, we explore black males’ responses to being rejected from nightclubs via dress code enforcement in predominately white settings. We contrast these responses to the general experiences of other black males who gained access. Although race is a factor in the enforcement of dress codes, we find a fluid relationship between race, class, and taste that influences black males’ responses and experiences. We illustrate how the nuanced reality of lived racial and class experiences for many young black males problematize the narrow interpretation of a black cultural essence.

Incidence, Depth and Severity of Children in Poverty

Recently, the first ever estimate of the number of children living poverty in developing countries was undertaken. The incidence of child poverty was estimated by establishing how many children suffer severe deprivation in at least one out of seven indicators which are internationally recognized as their rights as well as constitutive of poverty. This is a major step forward in the analysis of poverty. In this paper, we generalize these findings on the incidence of children living in poverty by exploring how to estimate the depth and severity of child poverty. Two countries can have the same proportion of children living in poverty, however, the actual plight of children could be very different depending on how many deprivations, on average, children suffer. In addition, even if they suffer from the same average number of deprivations, these deprivation could be the same for all children or be very unevenly distributed. We show how these considerations can be used to estimate the depth and severity of poverty. We use regional data to provide applied examples of this methodology. The method proposed in this paper is similar to the one used to estimate the incidence, depth and severity of income poverty. The paper also offers some possible generalizations and ways forward for future research.     

On the relationship between the reversed hazard rate and elasticity

Despite hazard and reversed hazard rates sharing a number of similar aspects, reversed hazard functions are far less frequently used. Understanding their meaning is not a simple task. The aim of this paper is to expand the usefulness of the reversed hazard function by relating it to other well-known concepts broadly used in economics: (linear or cumulative) rates of increase and elasticity. This will make it possible (i) to improve our understanding of the consequences of using a particular distribution and, in certain cases, (ii) to introduce our hypotheses and knowledge about the random process in a more meaningful and intuitive way, thus providing a means to achieving distributions that would otherwise be hardly imaginable or justifiable.     

When the Methodological Shoe is on the Other Foot: African American Interviewer and White Interviewees

Some scholars engaging in the insider/outsider debate have argued that the pairing of researcher and subjects based on racial similarity—i.e., “race matching”—is the most effective means for conducting qualitative research. Although insider/outsider status has been discussed with respect to white researchers' studies of African Americans, I explore the heretofore rarely discussed situation in which an African American is the researcher and whites are the subjects. I argue that insider status with respect to race continues to be based on a presumed connectedness linked to phenotypical characteristics—like skin color or hair texture. Yet, rather than experiencing a solely insider or outsider status, researchers and subjects experience what I call “insider moments” wherein their interests converge and they are able to share in the kinds of interactions that yield important insights. I conclude by evaluating the utility of insider/outsider status in qualitative research.     

Explaining the Mexican‐American Health Paradox Using Selectivity Effects

While typically socioeconomically disadvantaged, Mexican migrants in the United States tend to have better health outcomes than non‐Hispanic whites. This phenomenon is known as the “Hispanic health paradox.” Using data from Mexico and the United States, we examine several health outcomes for non‐Hispanic whites and Mexicans in the United States and in Mexico and employ Blinder–Oaxaca decompositions to help explain the paradox. We find evidence that selectivity is playing a significant role in the relatively healthy status of Mexican migrants in the United States. More importantly, there is evidence that health selectivity is a complex process and its effects typically do not work the same way for different health conditions and across genders. We also find evidence that some of migrants' health advantages are lost as they spend more time in the United States.     

WORKERS,WARRIORS, AND CRIMINALS: SOCIAL CONFLICT IN GENERAL EQUILIBRIUM

We incorporate appropriation activities (social conflict) into canonical models of trade and study how economic shocks and policies affect the intensity of conflict. We show that not all shocks that could make society richer reduce conflict: positive shocks to labor‐intensive industries diminish conflict, while positive shocks to capital‐intensive industries increase it. The key requirement is that conflict activities be more labor intensive than the economy as this determines how shocks affect the returns and costs of conflict. Our theory is consistent with several observed patterns of conflict and implies that empirical work should take into account the relative factor intensities of the productive and conflict sectors in each country. Incorporating appropriation into a canonic general equilibrium model affects what policies may be deemed desirable: in order to reduce conflict and generate Pareto‐improvements policy must be distortionary, while reforms that appear efficiency‐enhancing under the unrealistic assumption of perfect property rights may backfire. This offers one explanation for why reforms based on traditional models without appropriation may be delayed and become unpopular when implemented, and why societies may sympathize with seemingly inefficient redistribution.     

Evaluating the Move to a Linear Tax System in Germany and Other European Countries

This paper proposes a comparison of the results of tax policy analysis obtained on the basis of unitary and collective representations of the household. We first generate labour supplies consistent with the collective rationality, by use of a model calibrated on microdata as described in Vermeulen et al. [Collective Models of Household Labor Supply with Nonconvex Budget Sets and Nonparticipation: A Calibration Approach (2006)]. A unitary model is then estimated on these collective data and unitary and collective responses to a tax reform are compared. We focus on the introduction of linear taxation in Germany. The exercise is replicated for other European countries and other topical reforms. Distortions due to the use of a unitary model turn out to be important in predicting labour supply adjustments, in the design of tax revenue neutral reforms, and in predicting a reform’s welfare implications.
