This paper provides a critique of the ?unemployment invariance hypothesis,? according to which the behavior of the labor market ensures that the long-run unemployment rate is independent of the size of the capital stock, productivity, and the labor force. Using Solow growth and endogenous growth...

Excessive nighttime light is known to have detrimental effects on health and on the environment (fauna and flora). The paper investigates the link between nighttime light pollution and economic growth, air pollution, and urban density. We propose a county model of consumption which accounts for...

This paper examines the relationship between financial development, CO2 emissions, trade and economic growth using simultaneous-equation panel data models for a panel of 12 MENA countries over the period 1990-2011. Our results indicate that there is evidence of bidirectional causality between...

The answer is that people's evaluations of their income situation are based on different considerations when the economy is expanding and when it is contracting. When, in the course of economic growth, incomes generally are rising, evaluations tend to be dominated by "social comparison"—what...

In this note we compare the laissez-faire steady-state solution in the Howitt and Aghion (1998) model to the social optimum. The analysis offers several new insights in comparison to the welfare analysis in Aghion and Howitt (1992). We find various new distortions between private and optimal...

This paper presents a dynamic model that analyzes how firms' expectations with regards to technological change influence the demand for outsourcing. We show that outsourcing becomes more beneficial to the firm when technology is changing rapidly. As the pace of innovations in production...

We present a dynamic model where the probability of outsourcing production is increasing in the firm's expectation of technological change. As the pace of innovations in production technologies increases, the less time the firm has to amortize the sunk costs associated with purchasing and...

We use a calibrated stochastic life-cycle model of endogenous health spending, asset accumulation and retirement to investigate the causes behind the increase in health spending and life expectancy over the period 1965-2005. We estimate that technological change along with the increase in the...
