In a neoclassical economy with endogenous capital- and labor-augmentingtechnical change the steady-state growth rate of output per worker is shown to increasein the elasticity of substitution between capital and labor. This conrms theassessment of Klump and de La Grandville (2000) that the...

An analytical framework is developed to study the repercussions betweenendogenous capital- and labor-saving technical change and population aging.Following an intuition often attributed to Hicks (1932), I ask whether and howpopulation aging aects the relative scarcity of factors of production,...

We study the eect of a declining labor force on the incentives to engage in labor-savingtechnical change and ask how this eect is inuenced by institutional characteristics of the pensionscheme. When labor is scarcer it becomes more expensive and innovation investments that increaselabor...

This research empirically establishes the hypothesis that the process of population aging in a society as a whole affects the attitudes of its members towards immigration. Hence, an aging social environment exerts an effect on the attitudes of individuals towards immigration after accounting for...

Prettner (2019) studies the implications of automation for economic growth and the labor share in a variant of the Solow-Swan model. The aggregate production function allows for two types of capital, traditional and automation capital. Traditional capital and labor are imperfect substitutes...

A trade union whose purpose is to raise wages above the competitive level may foster economic growth if it succeeds in shifting income away from the owners of capital to the workers and if the workers' marginal propensity to save exceeds the one of capitalists. We make this point in an...

At least since 1870 hours worked per worker declined and real wages increased in many of today’s industrialized countries. The dual nature of technological progress in conjunction with a consumption-leisure complementarity explains these stylized facts. Technological progress drives real wages...

This paper introduces tasks into the neoclassical production sector. Competitive firms choose the profit-maximizing amounts of factor-specific tasks that determine their factor demands and output supplies. We show that the effect of factor-augmenting technical change on relative and absolute...

The functional income distribution in the US and most OECD countries has been characterized by an increasing capital income share and a declining wage share over the last decades. We present new evidence for the US economy that this fact is not only explained by technical change and...
