We use a simple graphical approach to represent Social Welfare Functions that satisfy Independence of Irrelevant Alternatives and Anonymity. This approach allows us to provide simple and illustrative proofs of May's Theorem, of variants of classic impossibility results, and of a recent result on...

We propose a broad generalization of standard choice-theoretic welfare economics that encompasses a wide variety of non-standard behavioral models. Our approach exploits the coherent aspects of choice which those positive models typically attempt to capture. It replaces the standard revealed...

This paper studies the long run properties of intertemporal distortions in a broad class of second best economies. Our unified framework encompasses and extends many well known models, such as variants of the Ramsey taxation model with aggregate or idiosyncratic risk, and economies with...

The paper discusses a methodology for calculating the distribution of gains and losses from a policy change using data for a large sample of households. Estimates are based on the equivalent income function, which is money metric utility defined over observable variables. This enables...

Many studies measure capital stocks and effective tax rates for different industries, but they consider only tangible assets such as equipment, structures, inventories, and land. Some of these studies also have estimated that the welfare cost of tax differences among these assets under prior law...

This paper derives a portfolio diversification rationale for a trade policy regime that insures returns to nondiversifiable human capital investment. In the absence of complete insurance markets for human capital, the decentralized equilibrium is characterized by excessive specialization. The...

This article studies how liability for environmentally harmful discharges affects the incentives of firms to engage in cleanup and invest in precautions, as well as the incentives of consumers to purchase the goods whose production leads to discharges. Our main conclusion is that making firms...

We prove that in a closed economy without distortionary taxation, the welfare of a representative consumer is summarized to a first order by the current and expected future values of the Solow productivity residual in level and by the initial endowment of capital. The equivalence holds if the...

Most countries exhibit large and persistent geographical differences in wages, income and unemployment rates. A growing class of "place based" policies attempt to address these differences through public investments and subsidies that target disadvantaged neighborhoods, cities or regions. Place...

Natives benefit from immigration mainly because of production complementarities between immigrant workers and other factors of production, and these benefits are larger when immigrants are sufficiently `different' from the stock of native productive inputs. The available evidence suggests that...
