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.

Konjunktur aktuell: Aufschwung in Deutschland setzt sich trotz nachlassender Impulse aus dem Ausland fort
Konjunktur aktuell,
No. 3,
2018
Abstract
Im Herbst 2018 ist die Weltkonjunktur weiterhin recht kräftig. Allerdings haben die regionalen Differenzen seit Jahresbeginn zugenommen. Während der Aufschwung in den USA auch wegen des starken Impulses durch die dortige Steuerreform noch einmal an Kraft gewonnen hat, ist die Konjunktur im Euroraum etwas schwächer geworden. Der Welthandel hat seit Jahresbeginn kaum noch zugelegt. Eine Ursache dieser Stagnation ist die Verschlechterung der handelspolitischen Rahmenbedingungen. Die Handelskonflikte sind allerdings nur einer von mehreren Risikofaktoren für die deutsche Konjunktur. Hinzu kommen die Möglichkeit eines ungeordneten Austritts Großbritanniens aus der EU im Frühjahr 2019 sowie ein weiterer Verlust an Vertrauen der Finanzmärkte in die Solvenz des italienischen Staates, falls die Regierung Italiens ihre finanzpolitischen Vorhaben in großem Stil umsetzt. Die deutsche Wirtschaft ist seit fünf Jahren im Aufschwung. Wichtige Treiber sind die außerordentlich günstigen Finanzierungsbedingungen und eine starke Expansion der Beschäftigung. Zuletzt hat die Nachfrage aus dem Ausland allerdings an Schwung verloren. Dabei spielt auch die Verteuerung deutscher Produkte aufgrund der Aufwertung des Euro seit dem Frühjahr 2017 eine Rolle. Die in diesem Jahr und besonders im Jahr 2019 expansiv ausgerichtete Finanzpolitik verschafft der Konjunktur Rückenwind, aber hohe Kapazitätsauslastungen und Engpässe beim Beschäftigungsaufbau dürften eine weitere kräftige Expansion behindern. Das reale Bruttoinlandsprodukt liegt nach vorliegender Prognose im Jahr 2018 um 1,8% höher als im Vorjahr, im Jahr 2019 beträgt die Rate 1,7%. Die ostdeutsche Wirtschaft expandiert in diesem Jahr um 1,5% und im Jahr 2019 um 1,4%.

Did the Swiss Exchange Rate Shock Shock the Market?
Manuel Buchholz, Gregor von Schweinitz, Lena Tonzer
Abstract
The Swiss National Bank abolished the exchange rate floor versus the Euro in January 2015. Based on a synthetic matching framework, we analyse the impact of this unexpected (and therefore exogenous) shock on the stock market. The results reveal a significant level shift (decline) in asset prices in Switzerland following the discontinuation of the minimum exchange rate. While adjustments in stock market returns were most pronounced directly after the news announcement, the variance was elevated for some weeks, indicating signs of increased uncertainty and potentially negative consequences for the real economy.

IWH-Tarif-Check,
No. 2,
2018
Abstract
Nach monatelangen Tarifverhandlungen gibt es für die rund 800 000 Beschäftigten im Bauhauptgewerbe einen Schlichterspruch – und die bislang höchste Tariflohnvereinbarung Deutschlands in diesem Jahr: Die Beschäftigten im Tarifgebiet West bekommen zum 1. Mai 2018 5,7% mehr Lohn und insgesamt drei Einmalzahlungen: im November diesen Jahres 250 Euro, im Juni 2019 600 Euro und im November 2019 noch einmal 250 Euro. Im Tarifgebiet Ost steigen die Tariflöhne ab Mai 2018 sogar um 6,6% und im Juni 2019 dann um 0,8%. Dazu kommt eine Einmalzahlung im November 2019 in Höhe von 250 Euro je Beschäftigten. Doch wie viel vom Plus bleibt den Bauarbeitenden wirklich? Das IWH hat die realen Einkommenszuwächse berechnet.

Economic Transition in Unified Germany and Implications for Korea
Hyung-Gon Jeong, Gerhard Heimpold
H.-G. Jeong and G. Heimpold (eds.): Economic Transition in Unified Germany and Implications for Korea. Policy References 17-13. Sejong: Korea Institute for International Economic Policy,
2017
Abstract
The reunification of Germany, which marked the end of the Cold War in the 20th century, is regarded as one of the most exemplary cases of social integration in human history. Nearly three decades after the German reunification, the economic and social shocks that occurred at the beginning of the reunification process have largely been resolved. Moreover, the unified Germany has grown into one of the most advanced economies in the world.
The unification process that Germany underwent may not necessarily be the way that the Republic of Korea would choose. However, the economic and social exchanges between East and West Germany prior to unification, and the cooperation in a myriad of policies based on these exchanges, served as the crucial foundation for unification. The case of Germany will surely help us find a better way for the re-unification of the Korean Peninsula.
In this context, this is the first edition of a joint research which provides diverse insights on social and economic issues during the process of unification. It consists of nine chapters whose main topics include policies on macroeconomic stabilization, the privatization of state-owned enterprises in East Germany, labor policies and the migration of labor, integration of the social safety nets of the North and South, and securing finances for reunification. To start with, the first part covers macroeconomic stabilization measures, which include policies implemented by the federal government of Germany to overcome macroeconomic shocks directly after the reunification. There was a temporary setback in the economy at the initial phase of reunification as the investment per GDP went down and the level of fiscal debt escalated, reverting to its original trend prior to the reunification. While it appears the momentum for growth was compromised by reunification from the perspective of growth rate of real GDP, this state did not last long and benefits have outpaced the costs since 2000.
In the section which examines the privatization of state-owned enterprises in East Germany, an analysis was conducted on the modernization of industrial infrastructure of East German firms. There was a surge in investment in East German area at the beginning stages but this was focused on a specific group of firms. Most of the firms were privatized through unofficial channels, with a third of these conducted in a management buy-out (MBO) process that was highly effective. Further analysis of a firm called Jenoptik, which was successfully bailed out, is incorporated as to draw implications of its accomplishments.
In the section on migration, we examine how the gap between the unemployment rates in the West and East have narrowed as the population flow shifted from the West to East. Consequently, there was no significant deviation in terms of the Gross Regional Domestic Product (GRDP) per capita in each state of East Germany. However, as the labor market stabilized in East Germany and population flows have weakened, the deviation will become larger. Meanwhile, if we make a prediction about the movement of population between the North and the South, which show a remarkable difference in their economic circumstances, a radical reunification process such as Germany’s case would force 7% of the population of the North to move towards the South. Upon reunification, the estimated unemployment rate in North Korea would remain at least 30% for the time being. In order to reduce the initial unemployment rate, it is crucial to design a program that trains the unemployed and to build a system that predicts changes in labor demand.
It seems nearly impossible to apply the social safety nets of the South to the North, as there is a systemic difference in ideologies. Taking steps toward integration would be the most suitable option in the case of the Koreas. We propose to build a sound groundwork for stabilizing the interest rates and exchange rates, maintain stable fiscal policies, raise momentum for economic growth and make sure people understand the means required to financially support the North in order to reduce the gap between the two.
This book was jointly organized and edited by Dr. Hyung-gon Jeong of the Korea Institute for International Economic Policy (KIEP) and Dr. Gerhard Heimpold of the Halle Institute for Economic Research (IWH). We believe that this report, which examines numerous social and economic agendas that emerged during the reunification of Germany, will provide truly important reference for both Koreas. It is also our view that it will serve as a stepping-stone to establish policies in regard to South-North exchanges across numerous sectors prior to discussions of reunification. KIEP will continue to work with IWH and contribute its expertise to the establishment of grounds for unification policies.

Banking Globalization, Local Lending, and Labor Market Effects: Micro-level Evidence from Brazil
Felix Noth, Matias Ossandon Busch
Abstract
This paper estimates the effect of a foreign funding shock to banks in Brazil after the collapse of Lehman Brothers in September 2008. Our robust results show that bank-specific shocks to Brazilian parent banks negatively affected lending by their individual branches and trigger real economic consequences in Brazilian municipalities: More affected regions face restrictions in aggregated credit and show weaker labor market performance in the aftermath which documents the transmission mechanism of the global financial crisis to local labor markets in emerging countries. The results represent relevant information for regulators concerned with the real effects of cross-border liquidity shocks.
