We use individual and multi-level data from Zambia on child nutritional health to test the absolute income hypothesis (AIH), the relative income hypothesis (RIH) and the income inequality hypothesis (IIH). The results confirm a non-linear positive relation between economic resources and health,...

We test whether people’s tendency to stick with the default option can help save resources. In a natural field experiment we switch printers’ default settings, from simplex to duplex printing, at a large Swedish university. The results confirm that roughly one third of all printing is...

In this paper the effects of unemployment on mental health are analysed. A simple model where both the occurrence of and duration of unemployment are allowed to affect mental health is specified. Panel data are used to control for "fixed effects", i.e. omitted variables that are constant over...

The role of school principals largely resembles that of corporate managers and the leadership they provide are often viewed as a crucial component for educational success. We estimate the impact of individual principals on various schooling outcomes, by constructing a principal-school panel data...

Declining fertility rates and increasing life expectancy necessitate a higher labor participation rate among older people in order to sustain pension systems and boost economic growth. At the same time, researchers have only recently begun to pay attention to the health effects of a longer...

This essay contributes in two ways to the literature on the effects of economic circumstances on health. First, it deals with reverse causality and omitted variable bias by exploiting exogenous variation in inherited wealth generated by the unexpected repeal of the Swedish inheritance tax....

We use administrative data on Swedish lottery players to estimate the causal impact of wealth on players' own health and their children's health and developmental outcomes. Our estimation sample is large, virtually free of attrition, and allows us to control for the factors such as the number of...

Research on entrepreneurship has flourished in recent years and is evolving rapidly. This paper explores the history of entrepreneurship research, how the research domain has evolved, and its current status as an academic field. The need to concretize these issues stems partly from a general...

Rapid price decreases for ICT-products in the 1990s have been largely attributed to the introduction of hedonic price indexes. Would hedonic price indexing also have large effects on measured price and productivity during other technological breakthroughs? This paper investigates the impact of...

This study compares average earnings and productivities for men and women employed in roughly 200,000 Chinese industrial enterprises. Women’s average wages lag behind men’s wages by 11%, and this result is robust to the inclusion of non-wage income in the form of social insurance payments....
