Product lines and new product introduction: Competition versus cannibalization in the personal computer industry
We examine the adoption by personal computer manufacturers of newly developed Intel processors. We find that firms that currently offer the top-of-the-line processor are more likely to be early adopters of a newly developed chip, regardless of whether or not that chip is the new top-of-the-line processor. Firms that are currently offering a processor that is adjacent in performance to a new chip, but slower, are not more likely to adopt that chip…

Passenger Shipping Cartels and Their Effect on Trans-Atlantic Migration
We investigate the impact of passenger shipping cartels on trans-Atlantic migration during the early twentieth century. We assemble from primary sources a detailed database of passenger flows and cartel operations and show that cartel operation reduced migratory flows by approximately 20% to 25%. Further, we show that there was no strong intertemporal substitution in migration to North America (at least in the short run) and, therefore, that the …
Incentives for environmental self-regulation and implications for environmental performance
Sampling Frequency and the Comparison Between Matched-Model and Hedonic Regression Price Indexes
Matched-model price indexes generally overestimate quality-adjusted prices, because the price/performance ratio of models sold in consecutive periods is worse than that of new models. This “unrepresentativeness” of the sample potentially might be reduced by obtaining higher-frequency data, thus increasing the fraction of models that are matched. We propose a set of comformable indexes to test this hypothesis. Using computer prices from the Buy Di…
Catalogue’ vs ‘Order‐of‐sale’ Effects in Sequential Auctions: Theory and Evidence from a Rare Book Sale
We examine bidding in a rare book sequential auction that has features of a natural experiment: lots were arranged in alphabetical order, the reserve set non-strategically and half the bids placed by mail-in bidders. We distinguish between the effects induced by the print order of the catalogue from those by the sequential nature of the sale. We document the existence of distinct 'catalogue' effects on prices, number of bids, and price variabilit…
The Small-Sample Bias of the Gini Coefficient: Results and Implications for Empirical Research
The Gini coefficient is a downward-biased measure of inequality in small populations when income is generated by one of three common distributions. The paper discusses the sources of bias and argues that this property is far more general. This has implications for (i) the comparison of inequality among subsamples, some of which may be small, and (ii) the use of the Gini in measuring firm size inequality in markets with a small number of firms. Th…
