Estimation Methods for Duration Models

This paper is a selected overview of econometric methods for duration models and will appear in the forthcoming book The Economics of Search by the authors. The focus of the paper is on martingale methods for continuous time data and general methods for the analysis of discretetime data including multi-spell models and general life-history models.

THE GROCERY STORES' WAGE DISTRIBUTION: A SEMI-PARAMETRIC ANALYSIS OF THE ROLE OF RETAILING AND LABOR MARKET INSTITUTIONS

How and why has the wage distribution in U.S. grocery stores changed between 1984 and 1994? Unlike other industries in the time period, the important change in the wage distribution is not rising inequality, but the real wages fell across the entire wage distribution. Changes in labor market institutions explain more than half of the change in the wage distribution in grocery stores. Specifically, the decline in the real value of the minimum wage explains little of the decline in the mean real wage but much of the change in the shape of the distribution between 1984 and 1994, and 95 percent of the decline at the lowest 10th percentile. The decline in union coverage in grocery stores and the narrowing of the union-nonunion wage gap explains much of the decline above the 25th percentile. A third institutional change, the use of part-time employees, is not associated with the changes in grocery industry wage outcomes. One might think that the major changes in operation and technologies that occurred during this time period are at least contributing factors, but we find quite the contrary. If average store size, weekly operating hours, and the use of scanning technology had remained at their 1984 levels, the real wage decline would have been even greater than that actually seen, and for the entire wage distribution. Changes in grocery retailing prevented and even greater decline in real wages. Again unlike many other industries, skill-biased technological change does not appear important for grocery industry wage outcomes. The basis of our analysis is a statistical technique which combines nonparametric kernel density estimation with a parametric re-weighting, applied to Current Population Survey data supplemented with secondary data sources on the Grocery industry.Agribusiness, Labor and Human Capital,

The Capital Gap: Nollywood and the limits of informal trade

This article examines Nollywood as a creative industry based in Africa’s informal sector. By definition, the informal sector produces no financial records, so no quantitative economic data are presented. This research utilizes ethnographic methods and anthropological analysis to highlight the importance of the video movie industry to Nigerian people, its place in their economic life and its integral role in their culture. Nollywood’s intimacy with Nigerians has been achieved by way of the industry’s distinctive informal system of production and distribution. This same informality prevents the video industry from establishing financial legitimacy. Without the ability to generate capital, the industry is straining against its economic limits. Thus, the cultural success of Nollywood pushes it towards inevitable formalization and uncertain consequences

Juju and Justice at the Movies: Vigilantes in Nigerian Popular Videos

This article examines the rise of vigilantism in southeastern Nigeria. Two opposing discourses on Nigerian vigilantism are examined. The first is characterized by the valorization of vigilantes as heroes in popular Nigerian video movies. The second is represented by a recent Human Rights Watch (HRW) report denouncing the vigilantes as criminals. My research utilizes ethnographic research to contextualize the video movies as a means toward understanding the ideological gap between these discourses. A close analysis of the Issakaba video series reveals a subtle treatment of the vigilante phenomenon designed to appeal to an indigenous perspective that is cognizant of the inherent risks of vigilante justice but also aware of the limitations of reform strategies such as those proposed by the HRW report

The making of a masterpiece and the power of poetry: “An October Salmon” by Ted Hughes

The Making of a Masterpiece and the Power of Poetry: “An October Salmon” by Ted Hughes is a philosophical reflection based on my lived experiences and engagement with the poetry of Ted Hughes, with particular reference to his poem “An October Salmon”. It is directed phenomenologically and autoethnographically towards the idea of using the power of poetry in an educational context to promote and facilitate the teaching of “respect” for self, others and the world
