Does oil price uncertainty affect energy use?

Theory predicts that the presence of fixed costs affects the relationship between energy use and energy price changes, as the firm's output and investment decisions respond differently to energy price increases and decreases. The asymmetry in response to energy price changes is exacerbated by uncertainty with respect to future energy prices, but to date the empirical literature does not explicitly take uncertainty into account. The contribution of this paper is twofold. First, we develop a new measure of energy price uncertainty. Second, we apply the measure to explain energy use in 8 OECD countries between 1978 and 1996, trying to identify whether indeed energy price uncertainty effects the asymmetry resulting from changes in energy use.

Life Satisfaction

We analyze the determinants of global life satisfaction in two countries (The Netherlands and the U.S.), by using both self-reports and responses to a battery of vignette questions. We find global life satisfaction of happiness is well-described by four domains: job or daily activities, social contacts and family, health, and income. Among the four domains, social contacts and family have the highest impact on global life satisfaction, followed by job and daily activities and health. Income has the lowest impact. As in other work, we find that American response styles differ from the Dutch in that Americans are more likely to use the extremes of the scale (either very satisfied or very dissatisfied) than the Dutch, who are more inclined to stay in the middle of the scale. Although for both Americans and the Dutch, income is the least important determinant of global life satisfaction, it is more important in the U.S. than in The Netherlands. Indeed life satisfaction varies substantially more with income in the U.S. than in The Netherlands.happiness, life satisfaction, vignettes, reporting bias

Work Disability, Work, and Justification Bias in Europe and the U.S.

To analyze the effect of health on work, many studies use a simple self-assessed health measure based upon a question such as “do you have an impairment or health problem limiting the kind or amount of work you can do?” A possible drawback of such a measure is the possibility that different groups of respondents may use different response scales. This is commonly referred to as “differential item functioning” (DIF). A specific form of DIF is justification bias: to justify the fact that they don’t work, non-working respondents may classify a given health problem as a more serious work limitation than working respondents. In this paper we use anchoring vignettes to identify justification bias and other forms of DIF across countries and socio-economic groups among older workers in the U.S. and Europe. Generally, we find differences in response scales across countries, partly related to social insurance generosity and employment protection. Furthermore, we find significant evidence of justification bias in the U.S. but not in Europe, suggesting differences in social norms concerning work.Work limiting disability, Vignettes, Reporting bias

Threshold effects of energy price changes

This paper presents a theoretical model emphasising energy investments’ characteristics of uncertainty and irreversibility. The theoretical model suggests threshold effects. Firms are induced to substitute away from energy only if prices of energy exceed a certain threshold level and they reverse the technology only if energy prices are low enough. Estimating a simple investment relation using panel data for the Dutch economy, we find evidence for threshold effects.
