In this paper, I construct a novel data set from individual curriculum vitae of economists at the top 100 US departments to study gender differences in the drivers of scholarly performance. Using a Shapley decomposition procedure to estimate the contribution of each driver in explaining the variation in mean and inequality of research performance, I find that for women, current placement is a more important driver of performance and inequality in performance compared to men. For men, co-authorship is the most important driver. Overall, my results suggest that networks are the key driver of performance and of inequality in performance. JEL codes: A14, J16, J24

This paper provides evidence for the size and the cyclicality of firing costs for the United States and Germany. In contrast to the existing literature, we use the optimality conditions obtained in a search and matching model to find a reduced form equation for firing costs. We find that our estimates are slightly larger compared with other studies and document sizable time-variation in firing costs.

This paper models a segmented production sector with price bargaining between the intermediate good firm and the final good firm. We show how to incorporate price bargaining in an otherwise standard New Keynesian model and discuss its macroeconomic implications. Estimating the model on U.S. data using Bayesian methods, we find that the intermediate good firm has 50 percent of the bargaining power. We find that the size of the bargaining power determines the quantitative and qualitative macroeconomic effects. Further, we quantify the size of switching costs: they are equal to about two percent of output. Shocks to switching costs are specific to this model and generate sizable macroeconomic fluctuations.

AbstractThis paper provides an overview of research into the phenomenon of whether climatic factors, such as temperature and weather‐related disasters, affect the decision to migrate. As an example, we examine migration flows from 198 countries to Australia for the time span from 1980 to 2015. Our results show that temperature does not have a robust, significant effect on migration flows, while weather‐related disasters do significantly affect flows to Australia.

Abstract
This paper makes a contribution to the literature on the driving forces of international migration. In contrast to the existing literature we consider the effect of socioeconomic variables (population dynamics, education and health, and openness) on migration flows. Especially the effects of openness of a society have not received much attention in the scientific debate.We use a panel data set of bilateral migration flows between 16 destination and 198 origin countries over the time span from 1980 to 2015. Most importantly, we find that our socioeconomic variables significantly affect the migration decision. Including socioeconomic variables does affect the size of the effects of the commonly used variables in the literature.Further, we find robust evidence that the socioeconomic variables at hand have non-linear effects on migration. For example, we find that the effect of human capital on migration follows an inverted U-shaped pattern.

AbstractThis paper develops and estimates catastrophe‐augmented models of the financial crisis. We employ catastrophe theory to explain discontinuous jumps in state variables of dynamic systems. We estimate an augmented bank failure model showing that the buildup of risk and an increase in the Federal Funds rate combined with low reserves (negative insurance effect) have been the main drivers of the financial crisis. Therefore, macroprudential policy and rating agencies play a key role in preventing the buildup of (systemic) risk and preventing the economy from entering a bifurcation area.

This paper shows that the stance of fiscal policy does have significant impact on the conduct of monetary policy in the United States. Further, we document that the implied fiscal-monetary policy interactions are subject to regime instability, using a Markov-switching model. Then, we develop a microfoundation of regime switches using a cheap talk game between central bank and government. As a case study, we simulate the effects of regime switches within an otherwise standard New Keynesian model using the cheap talk game in the state-space of our model.

Purpose– The purpose of this paper is to introduce productivity-dependent firing costs into an otherwise standard endogenous separations matching model. The authors suggest an alternative to the standard fix cost approach and account for empirical evidence emphasizing that firing costs vary across workers. The authors show that the model with firing costs outperformes the model without firing costs and replicates the empirical facts fairly well. Furthermore, the authors present cross-country evidence that countries with stricter employment protection have a weaker Beveridge curve relation and surprisingly more volatile job flow rates.Design/methodology/approach– The authors begin the analysis at the intersection of labor and product markets. For this purpose, the authors derive a real business cycle model with search and matching frictions and endogenous separations. The authors enrich this set-up by introducing productivity-dependent firing costs.Findings– The authors show that the model with firing costs outperformes the model without firing costs and replicates the empirical facts fairly well.
