In this paper we empirically analyse two counterfactual situations facing an anti-trust authority following the merger of two of the largest international cigarette companies. First we estimate a nested logit model of demand for cigarettes. The implied elasticity of demand for smoking and...

The static differentiated product demand model when applied to products with rapid product turnover and declining prices, yields implausible results. One response is to explicitly model the inter-temporal choices of consumers but computational demands require restrictive assumptions on consumer...

Casual empiricism suggests higher quality is associated with greater variety. However, recent theoretical and empirical research has either not considered this link, or has been unable to establish unambiguous predictions about the relationship between quality and variety. In this paper we...

The contributions of innovations, factor endowments and institutions to American industrialization are examined through analysing the rise of the American portland cement industry. Minerals abundance contributed in multiple ways to the spectacular rise of the industry from the 1890s. However,...

Unobserved plant level heterogeneity and discrete production processes can produce problems for estimation. A structural model of discrete production decisions by heterogeneous plants is constructed and, as a case study, estimated for the U.S. Portland cement industry. A new estimator is...

Input flexibility, as measured by the ability of firms to vary input demand in the face of changes in input prices, is an important dimension of labor market flexibility. Using a new dataset, the authors analyze the impact of unionization on input flexibility in U.S. manufacturing from 1973 to...

Do unions really impede manufacturers' output flexibility? If so, in what ways? The authors propose a methodology for quantifying George Stigler's concept of output flexibility, and for decomposing the effects of unionization on average cost differences between union and non-union plants. Using...

The question of why more African Americans did not migrate earlier out of the stagnant and repressive South after emancipation remains open. Previous work has highlighted the role of demand and supply conditions. At the time, though, there was much concern about the role of emigrant agents who...
