A Note on the Large Sample Properties of Estimators Based on Generalized Linear Models for Correlated Pseudo‐observations

Pseudo‐values have proven very useful in censored data analysis in complex settings such as multi‐state models. It was originally suggested by Andersen et al., Biometrika, 90, 2003, 335 who also suggested to estimate standard errors using classical generalized estimating equation results. These results were studied more formally in Graw et al., Lifetime Data Anal., 15, 2009, 241 that derived some key results based on a second‐order von Mises expansion. However, results concerning large sample properties of estimates based on regression models for pseudo‐values still seem unclear. In this paper, we study these large sample properties in the simple setting of survival probabilities and show that the estimating function can be written as a U‐statistic of second order giving rise to an additional term that does not vanish asymptotically. We further show that previously advocated standard error estimates will typically be too large, although in many practical applications the difference will be of minor importance. We show how to estimate correctly the variability of the estimator. This is further studied in some simulation studies.     

The Rate of Return on Investment in Wine

Is wine an investment alternative to stocks and bonds? First, we review prior studies regarding the pecuniary rate of return to wine and other alternatives to financial assets. Next, we calculate the rate of return to holding red Bordeaux wine from 1986 to 1996 using a repeat‐sale regression. Finally, we contrast the financial performance of wine, both on an aggregate basis and for various portfolios, to that of other asset classes. We conclude that wine does not yield greater returns than financial assets, especially when the volatility of returns and transaction costs are taken into account.     

The value of children to gay and heterosexual fathers

Responses of 33 gay fathers were compared with those of 33 heterosexual fathers on the Value of Children scale, an empirical measure of the reasons for wanting to become a parent. Responses of gay fathers did not differ significantly from heterosexual fathers on the majority of the items of the inventory, but differences were found on two subscales, Tradition-Continuity-Security and Social Status. Item analysis of responses shows that gay fathers may have particularly significant reasons motivating them to become parents.

Islam and Processes of Minorisation among Ethnic Chinese in Indonesia: Oscillating between Faith and Political Economic Expediency

The main focus of studies on ethnic Chinese in Southeast Asia is generally their business acumen or the extent to which they are assimilated into their respective country of residence. This paper concentrates on a rather different aspect among this ethnic group, namely the influence of Islam amongst the Chinese, especially in Indonesia and Malaysia. This is a topic on which very little research has been done, especially in terms of identity and ethnicity together with processes of integration and assimilation—in relation to both other ethnic Chinese and the local communities in which they are socially imbedded. Because of the deficiency of empirical data, it is imperative that we understand the historical processes that lead up to the present marginalised position of this group of Chinese. As a consequence, the present paper employs a historical approach towards the study of the Chinese Muslims in their respective local communities.     

The Optimal Income Taxation of Couples

This paper analyzes the general nonlinear optimal income tax for couples, a multidimensional screening problem. Each couple consists of a primary earner who always participates in the labor market, but makes an hours‐of‐work choice, and a secondary earner who chooses whether or not to work. If second‐earner participation is a signal of the couple being better (worse) off, we prove that optimal tax schemes display a positive tax (subsidy) on secondary earnings and that the tax (subsidy) on secondary earnings decreases with primary earnings and converges to zero asymptotically. We present calibrated microsimulations for the United Kingdom showing that decreasing tax rates on secondary earnings is quantitatively significant and consistent with actual income tax and transfer programs.     

“The right to lead”: Navajo language,dis‐citizenship,and Diné presidential politics

This article examines the 2014 Navajo Nation presidential primary election and language debate as a window into the politics of Navajo heritage language and identity. Using Facebook posts written in response to a videotaped hearing testing the fluency of one of the candidates that subsequently went viral, we analyse social citizenship and stigmatized language identities through the lens of critical Diné (Navajo) language consciousness. Focusing on generational differences between speaker groups that undergirded this debate, we analyse (a) the fluency test itself and (b) online and ethnographic responses to the fluency test. Using discourse analysis of Facebook posts of both heritage language and new Navajo speakers, we show how new speakers in particular express investment in their language and Diné cultural continuity and, through their emphasis on the heterogeneity of contemporary Diné communicative practices, offer an alternative template for ways to move forward in Diné language reclamation efforts.
