Marketing variables included in consumer discrete choice models are often endogenous. Extant treatments using likelihood-based estimators impose parametric distributional assumptions such as normality, on the source of endogeneity. These assumptions are restrictive as misspecified distributions have an impact on parameter estimates and associated elasticities. The normality assumption for endog...

self-incompatibility in almond and prunus species is an important genetic trait that prevents self-fertilization. self-incompatibility in almond is controlled gametophytically by the multiallelic s-locus. this study was done in order to identification and preliminary selection of self-compatible progenies resulted from controlled crosses in almond using specific primer sff-sfr.some important mo...

People tend to contribute more to a charity when they are asked to. Although this so-called ‘power of asking’ is well-known among fundraisers, the existing literature does not pay much attention to the role of donation requests in charitable giving. This paper uses a unique data set, which was designed to measure giving behavior in the United States, to estimate the causal effects of charitable...

Using a proprietary dataset provided by a major manufacturer of aircraft engines, we empirically investigate the impact of incentives present in after-sales repair and maintenance support contracts on product reliability. In particular, we compare the reliability of products under time and material (T&M) contracts, which have been used traditionally in the airline industry, with the reliability...

This paper analyzes the individual decision of online shopping, in terms of socioeconomic characteristics, internet related variables and location factors. Since online shopping is only observed for internet users, we use the two-step Heckman’s model to correct sample selection. We argue that one of the relevant variables to explain online shopping, the existence of a home internet connection, ...
