The value of the elasticity of substitution between labor and capital (ó) is a “crucial” assumption in understanding the secular decline in labor share of income (Piketty (2014a), Karabarbounis and Neiman (2014)) and long-run growth (Solow, 1956). This paper begins by examining the role of...

This paper aims to fill the gap between theoretical and empirical studies of home market effects (HMEs). On one hand, empirical studies on the price aspect of HMEs -- that wages are higher in larger markets -- are supportive, but studies on the quantity aspect -- that the firm share in the...

Estimating the degree of substitution between energy and non-energy inputs is key for any evaluation of environmental and energy policies. Yet, given the large variety of substitution elasticities, the central question arises as to which measure would be most appropriate. Apparently, ALLEN's...

We develop a framework to estimate the aggregate capital-labor elasticity of substitution by aggregating the actions of individual plants, and use it to assess the decline in labor's share of income in the US manufacturing sector. The aggregate elasticity reflects substitution within plants and...

Fischer Black provided a summary of my 1986 Princeton thesis. The idea in my thesis predates Epstein-Zin (1989). Black wrote:"Greenig (1986) explores time-nonseparable utility as a way of separating risk tolerance from elasticity of intertemporal substitution, and as a way of explaining things...

We develop a two-factor, two-sector trade model of monopolistic competition with variable elasticity of substitution. Firms' profits and sizes may increase or decrease with market integration depending on the degree of asymmetry between countries. The country in which capital is relatively...

This paper presents estimates for the consumption Euler equation for Russia. The estimation is based on micro-level panel data and accounts for the preference heterogeneity, measurement errors, and the impact of macroeconomic shocks. The presence of multiplicative habits is checked with the...

Sectoral heterogeneity is crucial to address several economic questions. This paper provides a detailed mapping of sectoral production possibility frontiers, using different nesting structures and levels of aggregation (primary, secondary, tertiary activities and energy-intensive firms)....

It has been shown that under perfect competition and a Cobb-Douglas production function, a basic real business cycle model may exhibit indeterminacy and sunspot fluctuations when income tax rates are determined by a balanced-budget rule. This paper introduces in an otherwise standard real...
