The Financial Channel of Wage Rigidity
Benjamin Schoefer
Econometrics Laboratory (EML),
April
2022
Abstract
I propose a financial channel of wage rigidity. In recessions, rigid average wages squeeze cash flows, forcing firms to cut hiring due to financial constraints. Indeed, empirical cash flows and profits would turn acyclical if wages were only moderately more procyclical. I study this channel in a search and matching model with financial constraints and wage rigidity among incumbent workers (but flexible new hires’ wages). While neither feature generates amplification individually, their interaction can account for much of the empirical labor market fluctuations—breaking the neutrality of incumbents’ wages for hiring, and showing that financial amplification of business cycles requires wage rigidity.

Involuntary Unemployment and the Business Cycle
Lawrence J. Christiano, Mathias Trabandt, Karl Walentin
Review of Economic Dynamics,
January
2021
Abstract
Can a model with limited labor market insurance explain standard macro and labor market data jointly? We construct a monetary model in which: i) the unemployed are worse off than the employed, i.e. unemployment is involuntary and ii) the labor force participation rate varies with the business cycle. To illustrate key features of our model, we start with the simplest possible framework. We then integrate the model into a medium-sized DSGE model and show that the resulting model does as well as existing models at accounting for the response of standard macroeconomic variables to monetary policy shocks and two technology shocks. In addition, the model does well at accounting for the response of the labor force and unemployment rate to these three shocks.

Integrated Assessment of Epidemic and Economic Dynamics
Oliver Holtemöller
IWH Discussion Papers,
No. 4,
2020
Abstract
In this paper, a simple integrated model for the joint assessment of epidemic and economic dynamics is developed. The model can be used to discuss mitigation policies like shutdown and testing. Since epidemics cause output losses due to a reduced labor force, temporarily reducing economic activity in order to prevent future losses can be welfare enhancing. Mitigation policies help to keep the number of people requiring intensive medical care below the capacity of the health system. The optimal policy is a mixture of temporary partial shutdown and intensive testing and isolation of infectious persons for an extended period of time.

Industry in Recession — Growth Forces Dwindle
Claus Michelsen, Oliver Holtemöller, Torsten Schmidt, Stefan Kooths, Timo Wollmershäuser
Wirtschaftsdienst,
No. 10,
2019
Abstract
Die führenden deutschen Wirtschaftsforschungsinstitute haben ihre Konjunkturprognose für Deutschland in ihrer Gemeinschaftsdiagnose vom Herbst 2019 deutlich nach unten korrigiert. Gründe für die schwache Entwicklung sind die nachlassende weltweite Nachfrage nach Investitionsgütern, auf deren Export die deutsche Wirtschaft spezialisiert ist, politische Unsicherheiten und strukturelle Veränderungen in der Automobilindustrie. Die Finanzpolitik stützt hingegen die gesamtwirtschaftliche Expansion. Die zukünftige Entwicklung ist stark davon abhängig, ob die Handelskonflikte gelöst werden können und wie der Brexit ausgestaltet wird.

Do Start-ups Provide Employment Opportunities for Disadvantaged Workers?
Daniel Fackler, Michaela Fuchs, Lisa Hölscher, Claus Schnabel
ILR Review,
No. 5,
2019
Abstract
This article compares the hiring patterns of start-ups and incumbent firms to analyze whether start-ups offer relatively more job opportunities to disadvantaged workers. Using administrative linked employer–employee data for Germany that provide the complete employment biographies of newly hired workers, the authors show that young firms are more likely than incumbents to hire applicants who are older, foreign, or unemployed, or who have unstable employment histories, arrive from outside the labor force, or were affected by a plant closure. Analysis of entry wages shows that penalties for these disadvantaged workers, however, are higher in start-ups than in incumbent firms. Therefore, even if start-ups provide employment opportunities for certain groups of disadvantaged workers, the quality of these jobs in terms of initial remuneration appears to be low.

Innovation, Reallocation, and Growth
Daron Acemoglu, Ufuk Akcigit, Harun Alp, Nicholas Bloom, William R. Kerr
American Economic Review,
No. 11,
2018
Abstract
We build a model of firm-level innovation, productivity growth, and reallocation featuring endogenous entry and exit. A new and central economic force is the selection between high- and low-type firms, which differ in terms of their innovative capacity. We estimate the parameters of the model using US Census microdata on firm-level output, R&D, and patenting. The model provides a good fit to the dynamics of firm entry and exit, output, and R&D. Taxing the continued operation of incumbents can lead to sizable gains (of the order of 1.4 percent improvement in welfare) by encouraging exit of less productive firms and freeing up skilled labor to be used for R&D by high-type incumbents. Subsidies to the R&D of incumbents do not achieve this objective because they encourage the survival and expansion of low-type firms.

Do Startups Provide Employment Opportunities for Disadvantaged Workers?
Daniel Fackler, Michaela Fuchs, Lisa Hölscher, Claus Schnabel
IZA Discussion Paper Series,
forthcoming
Abstract
This paper analyzes whether startups offer job opportunities to workers potentially facing labor market problems. It compares the hiring patterns of startups and incumbents in the period 2003 to 2014 using administrative linked employer-employee data for Germany that allow to take the complete employment biographies of newly hired workers into account. The results indicate that young plants are more likely than incumbents to hire older and foreign applicants as well as workers who have instable employment biographies, come from unemployment or outside the labor force, or were affected by a plant closure. However, an analysis of entry wages reveals that disadvantageous worker characteristics come along with higher wage penalties in startups than in incumbents. Therefore, even if startups provide employment opportunities for certain groups of disadvantaged workers, the quality of these jobs in terms of initial remuneration seems to be low.

Economic Transition in Unified Germany and Implications for Korea

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.
