How do firms respond to technological advances that facilitate the automation of tasks? Which tasks will they automate, and what types of worker will be replaced as a result? We present a model that distinguishes between a task's engineering complexity and its training requirements. When two...

Korea imports all of its primary energy, which leads to high dependency and vulnerability related to its energy supply. Efficiency in the use of energy is a way to reduce dependency and emissions. This study provides empirical results of the stochastic production process in energy use. Special...

In the neoclassical production functions model technical change (TC) is assumed to be exogenous and it is specified as a function of time. However, some exogenous external factors other than time can also affect the rate of TC. In this paper we model TC via a combination of time trend (purely...

Substitutes for marital sexual gratification may impact the decision to marry. Proliferation of the Internet has made pornography an increasingly low-cost substitute. We investigate the effect of Internet usage, and of pornography consumption specifically, on the marital status of young men. We...

This paper develops a conceptual framework that can explain why economic development goes along with increases in body weight and obesity rates. We first introduce the concept of novelty consumption, which refers to an increase in food availability due to trade or innovation. Then we study how...

Unsere (Arbeits-)Welt scheint sich mit zunehmender Geschwindigkeit zu verändern. Der vorliegende Beitrag beschreibt zentrale Aspekte dieser Entwicklung und diskutiert ihre voraussichtlichen Auswirkungen auf Arbeit und Beschäftigung. Der Wandel ist weltweit spürbar und Roboter und Maschinen...

The world is changing rapidly. This paper describes key shifts and it discusses their likely impacts on employment-related aspects. Labor market pressures are felt around the globe, and robots and automation increasingly become reality. However, there will be no "end of work". Rather, it is that...

We offer an integrated explanation and empirical analysis of the polarization of U.S. employment and wages between 1980 and 2005, and the concurrent growth of low skill service occupations. We attribute polarization to the interaction between consumer preferences, which favor variety over...

We juxtapose the effects of trade and technology on employment in U.S. local labor markets between 1990 and 2007. Labor markets whose initial industry composition exposes them to rising Chinese import competition experience significant falls in employment, particularly in manufacturing and among...

This paper introduces a new concept in addition to the traditional measures of stocks of capital, labor, human capital and knowledge, to understand the Solow Residual: National Entrepreneurial Ecosystem (NEE). The NEE construct is based on a methodology that combines institutions and human...
