In this paper, we study the impact of the economic growth on the environment. First, we show that, at each income level, n determines the direction of environmental degradation, where n is the elasticity of substitution between consumption and the environment. That is, for n large enough, as...

This paper develops a graphical analysis and an analytical model that demonstrate how weak substitution can be used for non-market valuation. Both weak complementarity and weak substitution can be evaluated as restrictions that allow quantity or quality changes in non-market goods to be...

An axiomatic construction for lifecycle preferences accounting for the finiteness and the randomness of life duration is provided. We emphasise the role of intertemporal correlation aversion and explain why multiplication preferences provide an interesting alternative to additive preferences,...

The Federal Reserve's 2009 program to purchase $300 billion of U.S. Treasury securities represented an unprecedented intervention in the Treasury market and provides a natural experiment with the potential to shed light on the price elasticities of Treasuries and theories of supply effects in...

We study the implications of microeconomic heterogeneity for aggregate technology, showing that the aggregate elasticity of substitution between capital and labor can be expressed as a simple function of plant level structural parameters and sufficient statistics for plant heterogeneity. This...

We estimate the aggregate elasticity of substitution between capital and labor in the US manufacturing sector. We show that the aggregate elasticity of substitution can be expressed as a simple function of plant level structural parameters and sufficient statistics of the distribution of plant...

Are linear regression models reliable in testing whether high expected real interest rates encourage current savings and deferred consumption? Here, a Monte Carlo test shows that a linear model yields a fairly accurate estimate and small standard error, but is highly susceptible to specification...

One of the recurring themes in the sustainability literature has been the legitimacy of using an economic framework to account for natural resources. This paper examines the potential for substituting between different inputs in the generation of income, where the inputs include natural...

We discuss how the welfare ranking of fixed and flexible exchange rate regimes in a New Open Economy Macroeconomics model depends on the interplay between the degree of exchange rate pass-through and the elasticity of substitution between home and foreign goods. We identify combinations of these...
