Working Paper
The value of knowledge spillovers
This paper aims at quantifying the economic value of knowledge spillovers by exploring information contained in patent citations. We estimate a market valuation equation for semiconductor firms during the 1980s and 1990s, and find an average value in the amount of $0.6 to 1.2 million "R&D-equivalent" dollars for the knowledge spillovers as embodied in one patent citation. For an average semiconductor firm, such an estimate implies that the total value of knowledge spillovers the firm received during the sample period could be as high as half of its actual total R&D expenditures in the same period. This provides a direct measure of the economic values of the social returns or externalities of relevant technological innovations. We also find that the value of knowledge spillovers declines as the size of the firm's patent portfolio increases, and that self citations are more valuable than external citations, indicating a significant amount of tacit knowledge or know-how spillovers that occur within the firm.

Why are semiconductor prices falling so fast? Industry estimates and implications for productivity measurement
By any measure, price deflators for semiconductors fell at a staggering pace over much of the last decade. These rapid declines are typically attributed to technological innovations that lower constant-quality manufacturing costs. But, given Intel's dominance in the microprocessor market, those price declines may also reflect changes in Intel's profit margins. Disaggregate data on Intel's operations are used to explore these issues. There are three basic findings. First, the industry data show that Intel's markups from its microprocessor segment shrank substantially from 1993-99. Second, about 3-1/2 percentage points of the average 24 percent price decline in a price index for Intel's chips can be attributed to declines in these profit margins over this period. And, finally, the data suggest that virtually all of the remaining price declines can be attributed to quality increases associated with product innovation.

Working Paper
Shifting trends in semiconductor prices and the pace of technological progress
This paper examines three questions motivated by previous research on semiconductors and productivity growth: Why did semiconductor prices fall so rapidly in the second half of the 1990s, why has the rate of price decline slowed since 2001, and to what extent are these price swings associated with changes in the rate of advance in semiconductor technology? We show that the price swings are statistically significant and that they reflect changes in both price-cost markups and cost trends. Further analysis indicates that the shift to faster cost declines in the mid-1990s likely corresponded to a speed-up in the pace of advance in semiconductor technology; however, the slower cost declines since 2001 appear not to have been mirrored by a deceleration in technology. Consequently, researchers should be cautious about associating price or cost movements for semiconductors with changes in the pace of underlying technology even over moderately long periods.

Working Paper
The role of semiconductor inputs in IT hardware price decline: computers vs. communications
Sharp declines in semiconductor prices are largely responsible for observed declines in computer prices. Although communications equipment also has a large semiconductor content, communications equipment prices do not fall nearly as fast as computer prices. This paper partly resolves the puzzle-first noted by Flamm(1989)-by demonstrating that prices for chips used in communications equipment do not fall nearly as fast as prices for those chips used in computers, and those differences are large enough to potentially explain all of the output price differences.

Working Paper
Price measures for semiconductor devices
This note provides quality-adjusted price indexes and nominal shipments data for highly disaggregate classes of semiconductor devices. These data may be used to construct indexes under different assumptions from those used in indexes that are currently available. Because the construction of these building blocks require some assumptions, the indexes are compared with similar price measures constructed by Bruce Grimm (1998) and by the Bureau of Labor Statistics.
