Abstract
There are many economic theories that promote human capital as a key driver of a country’s economic growth, but it is challenging to test this theory empirically on a country level and causally interpret the coefficients due to several identification problems. We tried to answer this particular question by using a quasi-natural experiment that happened quarter century ago – the fall of communist block in Eastern Europe. We use a shock to a particular scientific field – economics, to test whether the future investment into that particular field resulted in increased welfare and economic growth. The economics paradigm that was governing all of the communist block ceased to exist. Human capital depreciated over night and all communist countries had to transit from planned economy to a market economy. In the following years countries had to adapt to market economy through additional investment in human capital and research. We find that countries which lack both of the two fourth mentioned components had 25 years later a relatively lower economic growth and wealth. Unlike economics, other fields such as physics and medicine did not go through the same process so we use them as a placebo effect for our study. We find that the relative ratio of citations between economics and physics in post-communist countries is increasing only 15 years after the “paradigm” shock which gives a suggestive evidence that timing of investment into particular scientific field matters the most.

Auswirkungen des gesetzlichen Mindestlohns im Handwerk in Sachsen-Anhalt
Hans-Ulrich Brautzsch, Birgit Schultz
Zeitschrift für Wirtschaftspolitik,
Nr. 2,
2018
Abstract
This paper examines the effects of the minimum wage introduction in Germany in 2015 on the skilled crafts sector in Saxony-Anhalt.
Using novel survey data on the skilled crafts sector in Saxony-Anhalt, we examine three questions: (1) How many employees are affected by the minimum wage introduction in the skilled crafts sector in Saxony-Anhalt? (2) What are the effects of the minimum wage introduction? (3) How did firms react to wage increase?
We find that about 8 % of all employees in the skilled crafts sector in Saxony-Anhalt are directly affected by the minimum wage introduction. A difference-in-difference estimation reveals no significant employment effects of the minimum wage introduction. We test for alternative adjustment strategies and observe a significant increase of output prices.

Flooded Through the Back Door: Firm-level Effects of Banks‘ Lending Shifts

Nr. 4,

Abstract
I show that natural disasters transmit to firms in non-disaster areas via their banks. This spillover of non-financial shocks through the banking system is stronger for banks with less regulatory capital. Firms connected to a disaster-exposed bank with below median capital reduce their employment by 11% and their fixed assets by 20% compared to firms in the same region without such a bank during the 2013 flooding in Germany. Relationship banking and higher firm capital also mitigate the effects of such negative cross-regional spillovers.

Abstract
This paper examines the effects of the minimum wage introduction in Germany in 2015 on the skilled crafts sector in Saxony-Anhalt. Using novel survey data on the skilled crafts sector in Saxony-Anhalt, we examine three questions: (1) How many employees are affected by the minimum wage introduction in the skilled crafts sector in Saxony- Anhalt? (2) What are the effects of the minimum wage introduction? (3) How have firms reacted to wage increase? We find that about 8% of all employees in the skilled crafts sector in Saxony-Anhalt are directly affected by the minimum wage introduction. A difference-in-difference estimation reveals no significant employment effects of the minimum wage introduction. We test for alternative adjustment strategies and observe a significant increase of output prices.

Employment Effects of Introducing a Minimum Wage: The Case of Germany
Oliver Holtemöller, Felix Pohle
Abstract
This paper contributes to the empirical literature on the employment effects of minimum wages. We analysed the introduction of a statutory minimum wage in Germany in 2015 exploiting cross-sectional variation of the minimum wage affectedness. We construct two variables that measure the affectedness for approximately 300 state-industry combinations based on aggregate monthly income data. The estimation strategy consists of two steps. We test for (unidentified) structural breaks in a model with cross-section specific trends to control for state-industry specific developments prior to 2015. In a second step, we test whether the trend deviations are correlated with the minimum wage affectedness. To identify the minimum wage effect on employment, we assume that the minimum wage introduction is exogenous. Our results point towards a negative effect on marginal employment and a positive effect on socially insured employment. Furthermore, we analyse if the increase in socially insured employment is systematically related to the reduction of marginal employment but do not detect evidence.

Complex-task Biased Technological Change and the Labor Market
Colin Caines, Florian Hoffmann, Gueorgui Kambourov
Review of Economic Dynamics,
April
2017
Abstract
In this paper we study the relationship between task complexity and the occupational wage- and employment structure. Complex tasks are defined as those requiring higher-order skills, such as the ability to abstract, solve problems, make decisions, or communicate effectively. We measure the task complexity of an occupation by performing Principal Component Analysis on a broad set of occupational descriptors in the Occupational Information Network (O*NET) data. We establish four main empirical facts for the U.S. over the 1980–2005 time period that are robust to the inclusion of a detailed set of controls, subsamples, and levels of aggregation: (1) There is a positive relationship across occupations between task complexity and wages and wage growth; (2) Conditional on task complexity, routine-intensity of an occupation is not a significant predictor of wage growth and wage levels; (3) Labor has reallocated from less complex to more complex occupations over time; (4) Within groups of occupations with similar task complexity labor has reallocated to non-routine occupations over time. We then formulate a model of Complex-Task Biased Technological Change with heterogeneous skills and show analytically that it can rationalize these facts. We conclude that workers in non-routine occupations with low ability of solving complex tasks are not shielded from the labor market effects of automatization.

Kalte Progression wird nach Einführung der Schuldenbremse ein zunehmendes Problem
Martin Altemeyer-Bartscher, Götz Zeddies
Wirtschaftsdienst,
Nr. 2,
2017
Abstract
Geringfügige Steuermehrbelastungen, die auf die kalte Progression bei der Einkommensteuer zurückzuführen sind, werden vom Steuerzahler kaum wahrgenommen. Überschreiten die kumulierten Mehrbelastungen allerdings nach einigen Jahren eine kritische Schwelle, entsteht gewöhnlich ein politischer Druck für die Korrektur der kalten Progression. Im Unterschied zu konjunkturbedingten Einnahmeschwankungen wird dieser Einnahmezyklus in den Regelungen zur Schuldenbremse nicht berücksichtigt. Eine Indexierung des Steuertarifs, d. h. eine automatische Korrektur der kalten Progression, könnte derartige Schwankungen verhindern.

The Drivers of Revenue Productivity: a New Decomposition Analysis with Firm-level Data
Filippo di Mauro, Giordano Mion, Daniel Stöhlker
ECB Working Paper,
Nr. 2014,
2017
Abstract
This paper aims to derive a methodology to decompose aggregate revenue TFP changes over time into four different components – namely physical TFP, mark-ups, quality and production scale. The new methodology is applied to a panel of EU countries and manufacturing industries over the period 2006-2012. In summary, patterns of measured revenue productivity have been broadly similar across EU countries, most notably when we group them into stressed (Italy, Spain and Slovenia) and non-stressed countries (Belgium, Finland, France and Germany). In particular, measured revenue productivity drops for both groups by about 6 percent during the recent crisis. More specifically, for both stressed and non-stressed countries the drop in revenue productivity was accompanied by a substantial dip in the proxy we use for TFP in quantity terms, as well as by a strong reduction in mark-ups.

Kalte Progression – Gefahr für die Stabilität der Schuldenbremse
Götz Zeddies
Wirtschaft im Wandel,
Nr. 5,
2016
Abstract
Geringfügige Steuermehrbelastungen, die auf die kalte Progression bei der Einkommensteuer zurückzuführen sind, werden vom Steuerzahler kaum wahrgenommen und bieten dem deutschen Staat daher die Möglichkeit für schleichende Steuererhöhungen. Überschreiten die kumulierten Mehrbelastungen allerdings nach einigen Jahren eine kritische Schwelle, entsteht gewöhnlich ein politischer Druck für die Korrektur der kalten Progression. Wie im Beitrag gezeigt wird, kann die kalte Progression somit Auslöser eines Einnahmezyklus sein. Im Unterschied zu konjunkturbedingten Einnahmeschwankungen findet dieser Einnahmezyklus in den Regelungen zur Schuldenbremse keine Berücksichtigung. Ob die Regierungen eigenverantwortlich einen ausreichenden Sicherheitsabstand zur maximal zulässigen Nettokreditaufnahme einhalten, um diesen Schwankungen vorzubeugen, ist fraglich. Eine Indexierung des Steuertarifs, die eine automatische Korrektur der kalten Progression vorsieht, könnte derartige Schwankungen verhindern und für ein weniger volatiles Einkommensteueraufkommen sorgen.
