The share economy : conquering stagflation by Martin L Weitzman ( Book )
12 editions published between 1984 and 1987 in English and Portuguese and held by 1,054 WorldCat member libraries worldwide
Argumenta que o trabalhador medio, bem como a economia como um todo, seriam beneficiados por um sistema participativo, vinculando-se uma parcela significativa da remuneracao dos empregados a algum indicador do desempenho das empresas. Conclui que a remuneracao de mao de obra atraves de um sistema participativo, liberara forcas para a prosperidade economica e o progresso social
Income, wealth, and the maximum principle by Martin L Weitzman ( Book )
10 editions published between 2003 and 2007 in English and held by 461 WorldCat member libraries worldwide
"The book will be valuable to students who want to formulate and solve dynamic allocation problems. It will also be of interest to any economist who wants to understand the results of the latest research on the relationship between comprehensive income accounting and wealth or welfare."--BOOK JACKET
A contribution to the theory of welfare comparisons by Martin L Weitzman ( Book )
13 editions published in 1999 in English and held by 100 WorldCat member libraries worldwide
Using only information based on current directly-observable market behavior, the paper shows how to make rigorous dynamic welfare comparisons among economies or economic situations having arbitrarily-different endowments and technologies, but sharing a common dynamic preference ordering. The correct answers to seemingly complicated questions, which intrinsically involve comparing wealth-like measures of dynamic well-being, can be translated isomorphically into a simple-minded story told in the familiar language of old-fashioned static consumer-welfare theory

Structural uncertainty and the value of statistical life in the economics of catastrophic climate change by Martin L Weitzman ( )
4 editions published in 2007 in English and held by 43 WorldCat member libraries worldwide
Using climate change as a prototype motivating example, this paper analyzes the implications of structural uncertainty for the economics of low-probability high-impact catastrophes. The paper shows that having an uncertain multiplicative parameter, which scales or amplifies exogenous shocks and is updated by Bayesian learning, induces a critical "tail fattening" of posterior-predictive distributions. These fattened tails can have strong implications for situations (like climate change) where a catastrophe is theoretically possible because prior knowledge cannot place sufficiently narrow bounds on overall damages. The essence of the problem is the difficulty of learning extreme-impact tail behavior from finite data alone. At least potentially, the influence on cost-benefit analysis of fat-tailed uncertainty about the scale of damages -- coupled with a high value of statistical life -- can outweigh the influence of discounting or anything else
Bonuses and employment in Japan by Richard B Freeman ( Book )
7 editions published between 1986 and 1998 in English and held by 39 WorldCat member libraries worldwide
Japan has a relatively unique system of labor compensation. Most Japanese workers are paid large bonuses twice a year. This paper examines the cyclical movement of bonuses compared with wages and the relation of bonuses to employment in the context of the Weitzman "share economy." The paper makes three basic points:(1) The Japanese bonus is much more pro-cyclical than Japanese base wages, but not as cyclically variable as profits. Bonuses can be interpreted as containing a quantitatively significant revenue or profit-sharing component.(2) Bonuses have quite different employment consequences than do base wages. Even after controlling for other economic factors, bonuses are positively related to employment, whereas base wages are negatively related to employment.(3) The bonus system of paying workers, while far from explaining the whole macroeconomic story in Japan, seems to play a role in helping to stabilize Japanese unemployment at comparatively low levels

GHG targets as insurance against catastrophic climate damages by Martin L Weitzman ( )
5 editions published in 2010 in English and held by 35 WorldCat member libraries worldwide
A critical issue in climate-change economics is the specification of the so-called "damages function" and its interaction with the unknown uncertainty of catastrophic outcomes. This paper asks how much we might be misled by our economic assessment of climate change when we employ a conventional quadratic damages function and/or a thin-tailed probability distribution for extreme temperatures. The paper gives some numerical examples of the indirect value of various GHG concentration targets as insurance against catastrophic climate-change temperatures and damages. These numerical examples suggest that we might be underestimating considerably the welfare losses from uncertainty by using a quadratic damages function and/or a thin-tailed temperature distribution. In these examples, the primary reason for keeping GHG levels down is to insure against high-temperature catastrophic climate risks
The Ramsey Discounting Formula for a hidden-state stochastic growth process by Martin L Weitzman ( )
5 editions published in 2012 in English and held by 31 WorldCat member libraries worldwide
The long term discount rate is critically dependent upon projections of future growth rates that are fuzzier in proportion to the remoteness of the time horizon. This paper models such increasing fuzziness as an evolving hidden-state stochastic process. The underlying trend growth rate is an unobservable random walk hidden by noisy transitory shocks and recoverable only as a probability distribution via Bayesian updating. A simple expression is derived for the time-declining Ramsey discount rate. The components of this hidden-state Ramsey discounting formula are then analyzed, followed by a few remarks about possible implications and applications
A precautionary tale of uncertain tail fattening by Martin L Weitzman ( )
5 editions published in 2012 in English and held by 31 WorldCat member libraries worldwide
Suppose that there is a probability density function for how bad things might get, but that the overall rate at which this probability density function slims down to approach zero in the tail is uncertain. The paper shows how a basic precautionary principle of tail fattening could then apply. The worse is the contemplated damage, the more should a decision maker consider the bad tail to be among the relatively fatter-tailed possibilities. A rough numerical example is applied to the uncertain tail distribution of climate sensitivity
Risk-adjusted gamma discounting by Martin L Weitzman ( )
6 editions published in 2009 in English and held by 31 WorldCat member libraries worldwide
"It is widely recognized that the economics of distant-future events, like climate change, is critically dependent upon the choice of a discount rate. Unfortunately, it is unclear how to discount distant-future events when the future discount rate itself is unknown. In previous work, an analytically-tractable approach called "gamma discounting" was proposed, which gave a declining discount rate schedule as a simple closed-form function of time. This paper extends the previous gamma approach by using a Ramsey optimal growth model, combined with uncertainty about future productivity, in order to "risk adjust" all probabilities by marginal utility weights. Some basic numerical examples are given, which suggest that the overall effect of risk-adjusted gamma discounting on lowering distant-future discount rates may be significant. The driving force is a "fear factor" from risk aversion to permanent productivity shocks representing catastrophic future states of the world"--National Bureau of Economic Research web site

Rare disasters, tail-hedged investments, and risk-adjusted discount rates by Martin L Weitzman ( )
4 editions published in 2012 in English and held by 31 WorldCat member libraries worldwide
What is the best way to incorporate a risk premium into the discount rate schedule for a real investment project with uncertain payoffs? The standard CAPM formula suggests a beta-weighted average of the return on a safe investment and the mean return on an economy-wide representative risky investment. Suppose, though, that the project constitutes a tail-hedged investment, meaning that it is expected to yield positive payoffs in catastrophic states of nature. Then the model of this paper suggests that what should be combined in a weighted average are not the two discount rates, but rather the corresponding two discount factors. This implies an effective discount rate schedule that declines over time from the standard CAPM formula down to the riskfree rate alone. Some simple numerical examples are given. Implications are noted for discounting long-term public investments and calculating the social cost of carbon in climate change
A voting architecture for the governance of free-driver externalities, with application to geoengineering by Martin L Weitzman ( )
3 editions published in 2012 in English and held by 29 WorldCat member libraries worldwide
Climate change is a global "free rider" problem because significant abatement of greenhouse gases is an expensive public good requiring international cooperation to apportion compliance among states. But it is also a global "free driver" problem because geoengineering the stratosphere with reflective particles to block incoming solar radiation is so cheap that it could essentially be undertaken unilaterally by one state perceiving itself to be in peril. This paper develops the main features of a "free driver" externality in a simple model based on the asymmetric consequences of type-I and type-II errors. I propose a social-choice decision architecture based on the solution concept of a supermajority voting rule and derive its basic properties. In the model this supermajority voting rule attains the socially optimal cooperative solution, which is a new theoretical result around which the paper is built
