Theoretical work on price-setting behavior focuses on the single-product case while, in reality, a single price-setter sells many products. The authors use retail store-level multiproduct pricing data to learn about price dynamics. They find that, while the timing of a product's price changes is...

We find that while some individual price changes are indeed 'small', the average price change of different products within a store in any given month is not. Moreover, the smaller the price change of an individual product, the larger the average price change of the remaining products sold by the...

This paper analyzes the effects of inflation on the dispersion of prices, and other aspects of price behavior, using disaggregated data on prices of foodstuffs in Israel during 1978-84. The authors find that expected inflation has a stronger effect on intramarket price variability than...

Economists have long viewed recessions as contributing to increasing inequality. However, this conclusion is largely based on data from a period in which inequality was increasing over time. This paper examines the connection between long-run trends and cyclical variation in earnings inequality....

Much recent work has suggested that endogenous technological change tends to reinforce the position of the leading nations. Yet from time to time this leadership role shifts. We suggest a mechanism that explains this pattern of -leapfrogging- as a response to occasional major changes in...

After the initial breakthrough in the research phase of R&D a new product undergoes a process of change, improvement and adaptation to market conditions. We model the strategic behavior of firms in this development phase of R&D. We emphasize that a key dimension to this competition is the...

Is there any empirical evidence that firms become more efficient after becoming exporters? Do firms that become exporters generate positive spillovers for domestically-oriented producers? In this paper we analyze the causal links between exporting and productivity using firm-level panel data...

We show that economic incentives affect the number and commercial value of inventions generated in universities. Using panel data for 102 U.S. universities during the period 1991-1999, we find that universities which give higher royalty shares to academic scientists generate more inventions and...

In evaluating the effect of an R&D subsidy we need to know what the subsidized firm would have spent on R&D had it not received the subsidy. Using data on Israeli manufacturing firms in the 1990s we find evidence suggesting that the R&D subsidies granted by the Ministry of Industry and Trade...
