This paper argues that openness to new, unconventional and disruptive ideas has a first-order impact on creative innovations-innovations that break new ground in terms of knowledge creation. After presenting a motivating model focusing on the choice between incremental and radical innovation,...

This paper develops a simple framework to estimate the parameters of the production function together with the elasticity of the demand for the output and the impact of demand and cost shifters. The use of this framework helps, in the first place, to treat successfully the difficult problem of...

We propose a new measure of the economic importance of each innovation. Our measure uses newly collected data on patents issued to US firms in the 1926 to 2010 period, combined with the stock market response to news about patents. Our patent- level estimates of private economic value are...

We introduce a tractable model of endogenous growth in which the returns to innovation are determined by the technology adoption decisions of the users of new technologies. Technology adoption involves an implementation investment that determines the initial productivity of a new technology....

The revival of interest in nominal GDP (NGDP) targeting has come in the context of large advanced economies. We consider the case for NGDP targeting for mid-sized developing countries, in light of their susceptibility to supply shocks and terms of trade shocks. For India, in particular, one...

Innovation is often predicated on discovering useful new combinations of existing knowledge in highly complex knowledge spaces. These needle-in-a-haystack type problems are pervasive in fields like genomics, drug discovery, materials science, and particle physics. We develop a...

Employing a sample of renowned U.S. inventors that combines biographical detail with information on the patents they received over their careers, we highlight the impact of early U.S. patent institutions in providing broad access to economic opportunity and in encouraging trade in new...

During the Industrial Revolution technological progress and innovation became the main drivers of economic growth. But why was Britain the technological leader? We argue that one hitherto little recognized British advantage was the supply of highly skilled, mechanically able craftsmen who were...

A defiining feature of modern economic growth is the systematic application of science to advance technology. However, despite sustained progress in scientific knowledge, recent productivity growth in the U.S. has been disappointing. We review major changes in the American innovation ecosystem...

We present a model embodying moderate amounts of nominal rigidities which accounts for the observed inertia in inflation and persistence in output. The key features of our model are those that prevent a sharp rise in marginal costs after an expansionary shock to monetary policy. Of these...
