We argue that the empirical evidence against the Capital Asset Pricing Model (CAPM) based on stock returns does not invalidate its use for estimating the cost of capital for projects in making capital budgeting decisions. Since stocks are backed not only by projects in place, but also the...

This paper examines whether there are complementarities between investments in ICT, R&D and organizational innovation, and the effects of different investment profiles on total factor productivity growth on Dutch firm-level data. We estimate an integrated model of investment profile adoption and...

In this paper we compare sources of economic growth in Japan and the United States from 1975 through 2003, focusing on the role of information technology (IT). We have adjusted Japanese data to conform to U.S. definitions in order to provide a rigorous comparison between the two economies. The...

Using pooled cross-section, time-series data for 44 industries over the decades of the 1960s, 1970s, and 1980s in the United States, I find no econometric evidence that computer investment is positively linked to TFP growth (over and above its inclusion in the TFP measure). However,...

Our study aims at assessing the actual importance of the two main channels usually contemplated in the literature through which upstream sector anticompetitive regulations may impact productivity growth: business investments in R&D and in ICT. We thus estimate what are the specific impacts of...

We develop and implement a methodology to disentangle various sources of capital misallocation, i.e., dispersion in static marginal products. Our strategy uses readily observable moments in firm-level data, e.g., capital and revenues, to measure the contributions of technological and...

We provide a theoretical model linking firm characteristics and expected returns. The key ingredient of our model is technological shocks embodied in new capital (IST shocks), which affect the profitability of new investments. Firms' exposure to IST shocks is endogenously determined by the...

We model early expectations about the value and technological importance ('quality') of a patented innovation as a latent variable common to a set of four indicators: the number of patent claims, forward citations, backward citations and family size. The model is estimated for four technology...
