Resolving the Missing Deflation Puzzle
Jesper Lindé, Mathias Trabandt
Abstract
We propose a resolution of the missing deflation puzzle. Our resolution stresses the importance of nonlinearities in price- and wage-setting when the economy is exposed to large shocks. We show that a nonlinear macroeconomic model with real rigidities resolves the missing deflation puzzle, while a linearized version of the same underlying nonlinear model fails to do so. In addition, our nonlinear model reproduces the skewness of inflation and other macroeconomic variables observed in post-war U.S. data. All told, our results caution against the common practice of using linearized models to study inflation and output dynamics.

Service providers in Berlin give boost to East German economy – implications of the Joint Economic Forecast and of official data on the East German economy in 2018
In its spring report, the Joint Economic Forecast group states that the upturn in Germany came to an end in the second half of 2018, mainly because the manufacturing sector is weakening due to a slowing international economy and to problems in the automotive industry. Accordingly, in places such as Saxony (1.2%), Thuringia (0.5%), and Saxony-Anhalt (0.9%), where manufacturing plays a particularly important role, gross domestic product (GDP) grew less than in Germany as a whole (1.4%).

No-deal Brexit would hit the German labour market particularly hard
The United Kingdom leaving the European Union without a deal would have consequences for international trade and labour markets in many countries, including outside Europe. Calculations by the Halle Institute for Economic Research (IWH) indicate: More than 600,000 jobs may be affected worldwide, but nowhere as many as in Germany.

IWH leads large scale EU research project on productivity
Is productivity growth slowing in industrialised countries? And if so, why? From the start of 2019, the Halle Institute for Economic Research (IWH) will be addressing these questions as the coordinator of a new EU project. Economists and statistics experts from nine European partners will collaborate on the three-year project, entitled MICROPROD. With a total budget of just under three million euros, it is the IWH’s largest EU project to date.

Information Feedback in Temporal Networks as a Predictor of Market Crashes

Abstract
In complex systems, statistical dependencies between individual components are often considered one of the key mechanisms which drive the system dynamics observed on a macroscopic level. In this paper, we study cross-sectional time-lagged dependencies in financial markets, quantified by nonparametric measures from information theory, and estimate directed temporal dependency networks in financial markets. We examine the emergence of strongly connected feedback components in the estimated networks, and hypothesize that the existence of information feedback in financial networks induces strong spatiotemporal spillover effects and thus indicates systemic risk. We obtain empirical results by applying our methodology on stock market and real estate data, and demonstrate that the estimated networks exhibit strongly connected components around periods of high volatility in the markets. To further study this phenomenon, we construct a systemic risk indicator based on the proposed approach, and show that it can be used to predict future market distress. Results from both the stock market and real estate data suggest that our approach can be useful in obtaining early-warning signals for crashes in financial markets.

Abstract
The Halle Institute for Economic Research (IWH) was founded in 1992 and operates three research departments: Macroeconomics, Financial Markets, and Structural Change and Productivity. The IWH’s research structure is designed to foster close interplay between micro and macroeconomic research, however it has its roots in the empirical research conducted on the transition from a planned to a market economy, with a particular focus on East Germany.

Abstract
Am 5. und 6. Dezember 2016 fand am Leibniz-Institut für Wirtschaftsforschung Halle (IWH) zum 17. Mal der IWH-CIREQ Macroeconometric Workshop statt. Die erfolgreiche Kooperation mit dem Centre inter- universitaire de recherche en economie quantitative (CIREQ) wurde in diesem Jahr um die George Washington University (GW) verstärkt. Als neuer Kooperationspartner wurde die seit Februar 2016 am IWH tätige Forschungsprofessorin Tara Sinclair, Ph.D., in diesem Jahr mit in die Auswahlkommission berufen. Der diesjährige Workshop befasste sich mit dem Thema „Inequality, Micro Data and Macroeconomics“.

Should Forecasters Use Real-time Data to Evaluate Leading Indicator Models for GDP Prediction? German Evidence
Katja Heinisch, Rolf Scheufele
Abstract
In this paper we investigate whether differences exist among forecasts using real-time or latest-available data to predict gross domestic product (GDP). We employ mixed-frequency models and real-time data to reassess the role of survey data relative to industrial production and orders in Germany. Although we find evidence that forecast characteristics based on real-time and final data releases differ, we also observe minimal impacts on the relative forecasting performance of indicator models. However, when obtaining the optimal combination of soft and hard data, the use of final release data may understate the role of survey information.
