The Effects of Fiscal Policy in an Estimated DSGE Model – The Case of the German Stimulus Packages During the Great Recession
Andrej Drygalla, Oliver Holtemöller, Konstantin Kiesel
Abstract
In this paper, we analyse the effects of the stimulus packages adopted by the German government during the Great Recession. We employ a standard medium-scale dynamic stochastic general equilibrium (DSGE) model extended by non-optimising households and a detailed fiscal sector. In particular, the dynamics of spending and revenue variables are modeled as feedback rules with respect to the cyclical component of output. Based on the estimated rules, fiscal shocks are identified. According to the results, fiscal policy, in particular public consumption, investment, transfers and changes in labour tax rates including social security contributions prevented a sharper and prolonged decline of German output at the beginning of the Great Recession, suggesting a timely response of fiscal policy. The overall effects, however, are small when compared to other domestic and international shocks that contributed to the economic downturn. Our overall findings are not sensitive to the allowance of fiscal foresight.

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.

Endogenous Institution Formation in Public Good Games: The Effect of Economic Education

IWH Discussion Papers,
No. 29,
2017
Abstract
In a public good experiment, the paper analyses to which extent individuals with economic education behave differently in a second-order dilemma. Second-order dilemmas may arise, when individuals endogenously build up costly institutions that help to overcome a public good problem (first-order dilemma). The specific institution used in the experiment is a communication platform allowing for group communication before the first-order public good game takes place. The experimental results confirm the finding of the literature that economists tend to free ride more intensively in public good games than non-economists. The difference is the strongest in the end-game phase, yielding in the conclusion that the magnitude of the end-game effect depends on the share of economists in the pool of participants. When it comes to the building-up of institutions, the individual efficiency gain of the institution and its inherent cost function constitute the driving forces for the contribution behaviour. Providing an investment friendly environment yields in economists contributing more to the institution than non-economists. Therefore, we make clear that first-order results of a simple public good game cannot be simply applied for second-order incentive problems.

Who Benefits from GRW? Heterogeneous Employment Effects of Investment Subsidies in Saxony Anhalt
Eva Dettmann, Mirko Titze, Antje Weyh
IWH Discussion Papers,
No. 27,
2017
Abstract
The paper estimates the plant level employment effects of investment subsidies in one of the most strongly subsidized German Federal States. We analyze the treated plants as a whole, as well as the influence of heterogeneity in plant characteristics and the economic environment. Modifying the standard matching and difference-in-difference approach, we develop a new procedure that is particularly useful for the evaluation of funding programs with individual treatment phases within the funding period. Our data base combines treatment, employment and regional information from different sources. So, we can relate the absolute effects to the amount of the subsidy paid. The results suggest that investment subsidies have a positive influence on the employment development in absolute and standardized figures – with considerable effect heterogeneity.

Joint Economic Forecast—Autumn 2017: Upturn Remains Robust—Amid Mounting Tensions
The German economic upturn has gained both in terms of strength and breadth. In addition to consumer spending, external trade and investments are now also contributing to economic expansion. These are the conclusions drawn by the economic research institutes in their autumn report for the German federal government. Whereas the very high economic momentum in the first half of the current year will slow slightly, expansion of economic output this year and next will exceed production capacity growth. As a result, overall capacity utilization will increase, with economic output exceeding potential output. Gross Domestic Product is likely to grow by 1.9 percent this year and by 2 percent in 2018 (calendar-adjusted: 2.2 and 2.1 percent, respectively).

Der demographische Wandel und kommunale Investitionen
Martin Altemeyer-Bartscher, Reint E. Gropp, Peter Haug
IWH Online,
No. 1,
2017
Abstract
Die Investitionstätigkeit der Kommunen in Deutschland hängt im Wesentlichen von der örtlichen Finanzkraft ab und weist daher eine erhebliche räumliche Streuung auf. Doch gewisse regionale Unterschiede bei den Investitionen sind durchaus angemessen, wenn man die zukünftigen Nutzungsintensitäten der überwiegend langfristig angelegten Infrastrukturausstattung berücksichtigt. Da vor allem dort mehr investiert wird, wo die Nutzungsintensität in den kommenden Jahren wächst, fallen die regionalen Unterschiede bei den kommunalen Investitionsausgaben nicht so stark ins Gewicht. Die Gefahr, dass Kommunen mit geringer Ertragskraft in einen Teufelskreis geraten, in dem ausbleibende Investitionen primär einen Verlust an Standortattraktivität verursachen, scheint – wenn überhaupt – nur in Einzelfällen gegeben. Hingegen ist vielerorts eine Trägheit bei der Anpassung der Investitionen an eine neue demographische Situation zu beobachten. So investieren einige finanzstarke, schrumpfende Kommunen im Hinblick auf die abnehmenden Nutzungsintensitäten relativ viel in ihre Infrastruktur, währenddessen zahlreiche wachsende Orte ihre Kapazitäten unzureichend erweitern. Investitionszuschüsse sollten weniger an die gegenwärtige Bevölkerung, sondern vielmehr an die erwartete zukünftige Bevölkerungsentwicklung gekoppelt werden. Damit könnte die Effizienz der kommunalen Investitionen deutlich erhöht werden.

Gender Quotas and Human Capital Formation: A Relative Deprivation Approach
Walter Hyll
German Economic Review,
No. 3,
2017
Abstract
We study a quota's effect on individual human capital investment incentives beyond merely altering individual's overall probability of being promoted. We assume that individuals sense relative deprivation from unfavorable (income) comparisons within their reference group and that comparisons take place within the same gender. The introduction of a female quota increases (decreases) the number of women (men) holding top positions. On one hand, the relative deprivation to which female individuals are subjected to increases. These female individuals respond to an increase in their relative deprivation by acquiring additional human capital which, because it enables them to increase their earnings, reduces their relative deprivation. On the other hand, male individuals invest less in human capital in response to a decrease in relative deprivation. We show that the human capital formed by women who are encouraged to do so by the quotas is larger than the human capital that men who are discouraged by the quotas refrain from forming. However, the positive human capital accumulation effect hinges on a certain level of ability by gender and on how much individuals perceive relative deprivation.

Non-linearity in the Finance-Growth Nexus: Evidence from Indonesia
Nuruzzaman Arsyad, Iftekhar Hasan, Wahyoe Soedarmono

2017
Abstract
This paper investigates the finance-growth nexus where bank credit is decomposed into investment, consumption, and working capital credit. From a panel dataset of provinces in Indonesia, it documents that higher financial development measured by financial deepening and financial intermediation exhibits an inverted U-shaped relationship with economic growth. This non-linear effect of financial deepening is driven by both investment credit and consumption credit. These results suggest that too much investment credit and, to a lesser extent, consumption credit are detrimental to economic growth. Ultimately, only financial intermediation associated with working capital credit has a positive and monotonic impact on economic growth.
