„From a Nobel best guess to plausible ranges on climate policy“

Abstract: As the most important driver of long-term project evaluation, from climate change policy to infrastructure investments, the social discount rate (SDR) has been subject to heated debate among economists. To uncover the extent and sources of disagreement, we report the results of a survey of over 200 experts that disentangles the long-term SDR into its component parts: the pure rate of time preference, the wealth effect, and the real risk-free interest rate. The mean recommended SDR is 2.27 percent, with a range from 0 to 10 percent. Despite disagreement on point values, more than three-quarters of experts are comfortable with the median SDR of 2 percent, and over 90 percent find an SDR in the range of 1 to 3 percent acceptable. Our disentangled data reveal that only a minority of responses are consistent with the Ramsey Rule, the theoretical framework dominating discounting policy. Instead, experts recommend that governmental discounting guidance should be updated to deal with uncertainty, relative prices, and alternative ethical approaches.

„Jobs and intimate partner violence in Ethiopia“

Most previous evidence on employment and Intimate Partner Violence (IPV) is based on correlational studies. While such correlations are illustrative they do not tell us whether employment affects IPV, whether IPV affects employment, or whether there is some other factor that affects both employment and IPV. We identify the effects of jobs on IPV by collaborating with large companies in Ethiopia to randomly assign jobs to female applicants. In the presentation I will present results from the first six month follow up.

„Regional Convergence at the County Level: The Role of Commuters“

Commuters spend their money in a different place from where they earn it, thereby constituting an important channel for cross-regional dependencies and shock propagation. We analyze their role for convergence at the county level by proposing a spatial weights matrix based on commuter flows. In contrast to the classical geography-based spatial weights matrices, this matrix captures asymmetric regional dependencies derived from agents‘ actual behavior. With this spatial weights matrix, we estimate a panel data model that is dynamic both in the time and space dimension. This allows us to capture to what extent a county’s growth depends both on its own past trajectory and on that of other counties to which it is connected by commuter flows. Applying our approach to German counties from 2002 to 2014, we find that (i) regional convergence has taken place with heterogeneous spatial effects, and (ii) commuter flows from poorer to richer counties are a notable feature of the convergence process.

„Shedding Light on the Spatial Diffusion of Disasters“

Climate research suggests that global warming will lead to more frequent and more extreme natural disasters. Most disasters are local events with effects on local economic growth. Hence, assessing their economic impacts with the help of econometric country-level analysis may lead to biased results. Moreover, correct identification is further complicated by the possibility that local shocks shift production and consumption to neighboring locations. In this paper, annual night-time light emission data covering about 24,000 grid cells for the years 1992-2013 are matched to geocoded information on meteorological and geological events. Spatial econometric panel methods are applied to account for interdependencies between locations. Interpreting variation in light emissions as reflecting changes in economic activity, findings convey evidence for pronounced local average treatment effects and strong spatial spillovers, particularly for weather shocks. In particular, results suggest that spatial shifts of economic activity after a natural disaster are a rather local phenomenon, stressing the importance of local adaptation policies. Moreover, substantial heterogeneity across income groups and regions is identified.
