Book Description
The study of the bias of new technologies is important both as part of the analysis of the nature of technology adoption and the direction of technological change, and to understand the distributional implications of new technologies. In this paper, I analyze the equilibrium bias of technology. I distinguish between the relative bias of technology, which concerns how the marginal product of a factor changes relative to that of another following the introduction of new technology, and the absolute bias, which looks only at the effect of new technology on the marginal product of a factor. The first part of the paper generalizes a number of existing results in the literature regarding the relative bias of technology. In particular, I show that when the menu of technological possibilities only allows for factor-augmenting technologies, the increase in the supply of a factor always induces technological change (or technology adoption) relatively biased towards that factor. This force can be strong enough to make the relative marginal product of a factor increasing in response to an increase in its supply, thus leading to an upward-sloping relative demand curve. However, I also show that the results about relative bias do not generalize when more general menus of technological possibilities are considered. In the second part of the paper, I show that there are much more general results about absolute bias. I prove that under fairly mild assumptions, an increase in the supply of a factor always induces changes in technology that are absolutely biased towards that factor, and these results hold both for small changes and large changes in supplies. Most importantly, I also determine the conditions under which the induced-technology response will be strong enough so that the price (marginal product) of a factor increases in response to an increase in its supply. These conditions correspond to a form of failure of joint concavity of the aggregate production function of the economy in factors and technology. This type of failure of joint concavity is quite possible in economies where equilibrium factor demands and technologies are decided by different agents.
Technological Change and the Environment
Author: Arnulf GrüblerPublisher: Routledge
ISBN: 1136522913
Category : Nature
Languages : en
Pages : 414
Book Description
Much is written in the popular literature about the current pace of technological change. But do we have enough scientific knowledge about the sources and management of innovation to properly inform policymaking in technology dependent domains such as energy and the environment? While it is agreed that technological change does not 'fall from heaven like autumn leaves,' the theory, data, and models are deficient. The specific mechanisms that govern the rate and direction of inventive activity, the drivers and scope for incremental improvements that occur during technology diffusion, and the spillover effects that cross-fertilize technological innovations remain poorly understood. In a work that will interest serious readers of history, policy, and economics, the editors and their distinguished contributors offer a unique, single volume overview of the theoretical and empirical work on technological change. Beginning with a survey of existing research, they provide analysis and case studies in contexts such as medicine, agriculture, and power generation, paying particular attention to what technological change means for efficiency, productivity, and reduced environmental impacts. The book includes a historical analysis of technological change, an examination of the overall direction of technological change, and general theories about the sources of change. The contributors empirically test hypotheses of induced innovation and theories of institutional innovation. They propose ways to model induced technological change and evaluate its impact, and they consider issues such as uncertainty in technology returns, technology crossover effects, and clustering.

Policy Uncertainty and Technology Adoption

ISBN:

Languages : en
Pages : 0
Book Description
This paper considers technology adoption under both technological and subsidy uncertainties. Uncertainty in subsidies for green technologies is considered as an example. Technological progress is exogenous and modeled as a jump process with a drift. The analytical solution is presented for cases when there is no subsidy uncertainty and when the subsidy changes once. The case when the subsidy follows a time-invariant Markov process is analyzed numerically. The results show that improving the innovation process raises the investment thresholds. When technological jumps are small or rare, this improvement reduces the expected time before technology adoption. However, when technological jumps are large or abundant, this improvement may raise this expected time.

Environmental Decisions in the Face of Uncertainty
Author: Institute of MedicinePublisher: National Academies Press
ISBN: 0309290236
Category : Political Science
Languages : en
Pages : 280
Book Description
The U.S. Environmental Protection Agency (EPA) is one of several federal agencies responsible for protecting Americans against significant risks to human health and the environment. As part of that mission, EPA estimates the nature, magnitude, and likelihood of risks to human health and the environment; identifies the potential regulatory actions that will mitigate those risks and protect public health1 and the environment; and uses that information to decide on appropriate regulatory action. Uncertainties, both qualitative and quantitative, in the data and analyses on which these decisions are based enter into the process at each step. As a result, the informed identification and use of the uncertainties inherent in the process is an essential feature of environmental decision making. EPA requested that the Institute of Medicine (IOM) convene a committee to provide guidance to its decision makers and their partners in states and localities on approaches to managing risk in different contexts when uncertainty is present. It also sought guidance on how information on uncertainty should be presented to help risk managers make sound decisions and to increase transparency in its communications with the public about those decisions. Given that its charge is not limited to human health risk assessment and includes broad questions about managing risks and decision making, in this report the committee examines the analysis of uncertainty in those other areas in addition to human health risks. Environmental Decisions in the Face of Uncertainty explains the statement of task and summarizes the findings of the committee.

Book Description
Griliches was a modern master of empirical economics. Here, he recounts what he and others have learned about the sources of economic growth, and conveys how he tackled research problems. For Griliches, theorizing without measurement produces mere parables, but measurement without theory is blind. Judgment enables one to strike the right balance.

Inequality and the Labor Market
Author: Sharon BlockPublisher: Brookings Institution Press
ISBN: 0815738811
Category : Law
Languages : en
Pages : 263
Book Description
Exploring a new agenda to improve outcomes for American workers As the United States continues to struggle with the impact of the devastating COVID-19 recession, policymakers have an opportunity to redress the competition problems in our labor markets. Making the right policy choices, however, requires a deep understanding of long-term, multidimensional problems. That will be solved only by looking to the failures and unrealized opportunities in anti-trust and labor law. For decades, competition in the U.S. labor market has declined, with the result that American workers have experienced slow wage growth and diminishing job quality. While sluggish productivity growth, rising globalization, and declining union representation are traditionally cited as factors for this historic imbalance in economic power, weak competition in the labor market is increasingly being recognized as a factor as well. This book by noted experts frames the legal and economic consequences of this imbalance and presents a series of urgently needed reforms of both labor and anti-trust laws to improve outcomes for American workers. These include higher wages, safer workplaces, increased ability to report labor violations, greater mobility, more opportunities for workers to build power, and overall better labor protections. Inequality in the Labor Market will interest anyone who cares about building a progressive economic agenda or who has a marked interest in labor policy. It also will appeal to anyone hoping to influence or anticipate the much-needed progressive agenda for the United States. The book's unusual scope provides prescriptions that, as Nobel Laureate Joseph Stiglitz notes in the introduction, map a path for rebalancing power, not just in our economy but in our democracy.
