We propose a unified growth theory to investigate the mechanics generating the economic and demographic transition, and the role of mortality differences for comparative development. The framework can replicate the quantitative patterns in historical time series data and in contemporaneous...

In this paper we measure knowledge spillovers arising from venture-capital financed companies on the patenting activities of other companies and compare them to spillovers from established firms. We develop a novel measure to to identify the appropriate spillover pool based on backward citations...

This paper investigates empirically firm investment behavior in research and development (R&D). Firms make investments in R&D in order to produce innovations. These innovations in turn improve the firm's future productivity level, pro tability and incentives to invest in R&D. Using German...

The self-employed constitute a large proportion of the workforce in developing countries and the sector has been found to be growing further. Different accounts exist as to the cause of this development, with pull factors such as high returns to capital and increased wealth contrasted with push...

Private transfers between households in developing countries have been extensively studied and shown to be economically important as mechanisms of risk sharing and income redistribution. We argue that migration and remittances have the potential to modify the prevalent transfer behaviour in...

We use a series of field experiments in the Palestinian Territories to explore the impact of exposure to shocks on risk, time and ambiguity preferences. We exploit the historical episode of the construction of the separation wall between the State of Israel and the West Bank as an exogenous...

This paper investigates the impact of a devastating weather shock on child anthropometrics, using data from Mongolia. We employ a diff-in-diff strategy to identify the effect of an extremely harsh winter in 2010, which caused the death of about 20 percent of the national livestock. Results...

Recent studies focused on testing the Easterlin hypothesis (happiness and national income correlate in the cross-section but not over time) on a global level. We make a case for testing the Easterlin hypothesis at the country level where individual panel data allow exploiting important...

The slow recovery following the 2008/2009 recession has led to renewed interest in the question whether deep recessions lower real GDP permanently or whether we can expect a rebound to earlier trend levels. Using a recent quantile autoregression unit root test we check whether shocks to real GDP...

This paper provides the exact analytical solution for the standard model of endogenous growth when consumers have present-biased preferences and make time-inconsistent savings plans, which they revise continuously. It is shown that long-run growth is not necessarily lower under present-biased...
