Original Sin - Analysing Its Mechanics and a proposed Remedy in a Simple Macroeconomic Model

IWH Discussion Papers,
No. 11,

Abstract
This paper analyses the problem of “original sin“ (the fact that the currency of an emerging market economy usually cannot be used to borrow abroad) in a simple thirdgeneration model of currency crises. The approach differs from alternative frameworks by explicitly modeling the price setting behavior of firms if prices are sticky and the future exchange rate is uncertain. Monetary policy optimally trades off effects on price competitiveness and on debt burdens of firms. It is shown that the proposal by Eichengreen and Hausmann of creating an artificial basket currency as denominator of debt is attractive as a provision against contagion.

Determinants of employment - the macroeconomic view
Christian Dreger, Heinz P. Galler, Ulrich (eds) Walwai
Schriften des IWH,
No. 22,
2005
Abstract
The weak performance of the German labour market over the past years has led to a significant unemployment problem. Currently, on average 4.5 mio. people are without a job contract, and a large part of them are long-term unemployed. A longer period of unemployment reduces their employability and aggravates the problem of social exclusion.
The factors driving the evolution of employment have been recently discussed on the workshop Determinanten der Beschäftigung – die makroökonomische Sicht organized jointly by the IAB, Nuremberg, and the IWH, Halle. The present volume contains the papers and proceedings to the policy oriented workshop held in November 2004, 15-16th. The main focus of the contributions is twofold. First, macroeconomic conditions to stimulate output and employment are considered. Second, the impacts of the increasing tax wedge between labour costs and the take home pay are emphasized. In particular, the role of the contributions to the social security system is investigated.
In his introductory address, Ulrich Walwei (IAB) links the unemployment experience to the modest path of economic growth in Germany. In addition, the low employment intensity of GDP growth and the temporary standstill of the convergence process of the East German economy have contributed to the weak labour market performance. In his analysis, Gebhard Flaig (ifo Institute, München) stresses the importance of relative factor price developments. A higher rate of wage growth leads to a decrease of the employment intensity of production, and correspondingly to an increase of the threshold of employment. Christian Dreger (IWH) discusses the relevance of labour market institutions like employment protection legislation and the structure of the wage bargaining process on the labour market outcome. Compared to the current setting, policies should try to introduce more flexibility in labour markets to improve the employment record. The impact of interest rate shocks on production is examined by the paper of Boris Hofmann (Deutsche Bundesbank, Frankfurt). According to the empirical evidence, monetary policy cannot explain the modest economic performance in Germany. György Barabas and Roland Döhrn (RWI Essen) have simulated the effects of a world trade shock on output and employment. The relationships have been fairly stable over the past years, even in light of the increasing globalization. Income and employment effects of the German tax reform in 2000 are discussed by Peter Haan and Viktor Steiner (DIW Berlin). On the base of a microsimulation model, household gains are determined. Also, a positive relationship between wages and labour supply can be established. Michael Feil und Gerd Zika (IAB) have examined the employment effects of a reduction of the contribution rates to the social security system. To obtain robust results, the analysis is done under alternative financing scenarios and with different macroeconometric models. The impacts of allowances of social security contributions on the incentives to work are discussed by Wolfgang Meister and Wolfgang Ochel (ifo München). According to their study, willingness to work is expected to increase especially at the lower end of the income distribution. The implied loss of contributions could be financed by higher taxes.

Employment effects of development of renewable energies
Steffen Hentrich, Jürgen Wiemers, Joachim Ragnitz
IWH-Sonderhefte,
No. 1,
2004
Abstract
Die Bundesregierung strebt bis zum Jahr 2010 eine Verdopplung des Anteils erneuerbarer Energien am Primärenergie- sowie am Bruttostromverbrauch an. Das vorrangige Ziel der damit verbundenen Umstrukturierung des Energiesektors ist die Verbesserung der Umweltqualität. Es darf jedoch nicht außer Acht gelassen werden, dass die Förderung erneuerbarer Energien zwangsläufig auch gesamtwirtschaftliche Auswirkungen hat. Angesichts der anhaltend angespannten Lage am Arbeitsmarkt stehen dabei insbesondere die Beschäftigungseffekte der Förderung erneuerbarer Energien im Mittelpunkt des öffentlichen und wirtschaftspolitischen Interesses. Vor diesem Hintergrund hat das Institut für Wirtschaftsforschung Halle im Auftrag des Bundesministeriums für Wirtschaft und Arbeit (BMWA) die gesamtwirtschaftlichen und insbesondere beschäftigungsrelevanten Auswirkungen des angestrebten Ausbaus erneuerbarer Energien untersucht. Im Gegensatz zu anderen Studien dieser Art wurde dabei besonderer Wert auf eine dynamische Analyse gelegt, die neben den expansiven Beschäftigungsimpulsen im Bereich der erneuerbaren Energien auch die gegenläufigen Beschäftigungswirkungen berücksichtigt, die durch Verdrängung konventioneller Energieträger und durch erhöhte Steuern zur Finanzierung von Subventionen für regenerative Energien entstehen. Die vorliegende Untersuchung gibt eine zusammenfassende Darstellung der Vorgehensweise und der Ergebnisse des Forschungsprojekts. Es zeigt sich, dass per saldo durch den verstärkten Ausbau erneuerbarer Energien keine zusätzliche Beschäftigung generiert wird.

Germany 2004: Only a transitory economic stimulus from moving tax cuts forward
Wirtschaft im Wandel,
No. 9,
2003
Abstract
In summer 2003 the German economy once again did not overcome the stagnation, which by now lasted three years. Only by the end of this year the German economy will begin to receive stronger support from a then further improved world economy. In the past months both US and European monetary policy have provided sufficient liquidity by lowering interest rates. In the USA, additional support is provided by fiscal policy; tax reductions and rebates increase domestic demand. Overall, Gross Domestic Product in the US will increase by 2.1% this year; in the euro area GDP will merely expand by a modest 0.8%. For Germany one of its key sectors will not be able to lift the economy as usual and GDP, when compared to last year, will only stagnate. Provided by the brought forward tax reform 2000 the coming year will begin with a stimulus to the German economy. The tax reductions, though, will have limited effect on aggregate production, as the increased consumption will not be able to stimulate investment. Accounting for calendar effects GDP in Germany will increase by at least 1% in 2004 compared with this year, but due to several additional working days in 2004, the unadjusted rate of expansion will be 1.7%. No substantial improvements are expected for the job market.

IWH Economic Outlook 2003: Waiting for the Upswing in Germany - Waiting for Godot?
Wirtschaft im Wandel,
No. 1,
2003
Abstract
The outlook forecasts the economic developments in the world, the Euro Area and Germany in 2003. A general tendency is given for 2004. The world economy and the US-economy are recovering in 2003 and so are providing positive impulses for the Euro Area. For Germany this impetus from abroad will most likely remain the sole driving force for the revival of economic activity in 2003. Still this external stimulus will not be able to develop its full strength, as the newly restrictive fiscal policy will lower disposable income. At the earliest the economic upturn will gain strength in the summer months. This results in an initially increased burden on the labour market and only in 2004 will a decline in unemployment be observable, albeit at a slow pace. In economic terms, the recent interest rate cut by the ECB should only be able to show modest effects. Fiscal Policy in 2003 will be distinctly restrictive.

Possible effects of demographic change - An overview
Gunter Steinmann, Olaf Fuchs, Sven Tagge
Wirtschaft im Wandel,
No. 15,
2002
Abstract
One of the more important influences shaping the future economic conditions of the highly industrialized countries is the decline and aging of their population. The article is a comprehensive survey of the impact of this development on key economic variables and the institutions of the welfare state. While the overall consequence of the aging process on productivity growth is more likely to be negative, there are also some offsetting forces like the increase in the capital intensity. The institutions of the welfare state, which are based on intergenerational transfers, will have to be reformed, in order to bring them in line with the demographic process. The prediction of a decrease in the rate of unemployment as a consequence of a declining labor force is according to our analysis not justified.

Business cycle news: Upswing in Germany delayed
Wirtschaft im Wandel,
No. 12,
2002
Abstract
In the wake of the most recent national accounts estimates, the IWH has reassessed its business cycle forecast. Additionally, the economic effects of the flood were analysed. While the latter should have neither a positive nor a negative impact on Germany’ business cycle as a whole, East Germany’s already weak economic expansion is seriously affected. At most GDP will stagnate. In contrast, next year the public and private restoration efforts will stimulate the Eastern German economy.

The flood disaster and GDP in Germany
Udo Ludwig, Hans-Ulrich Brautzsch
Wirtschaft im Wandel,
No. 12,
2002
Abstract
The flood at Elbe, Danube and their tributary streams destroyed billion Euros worth of Capital Stock. GDP, though, does not include Capital Stock, but production. On the basis of plausible assumptions the production interruptions caused by the flood are estimated for Germany and the most severely affected areas of Saxony and Saxony-Anhalt. Considering the “set-aside” funds for restoration and with the help of the Input-Output-Model the direct effects on production and employment within the different economic sectors are being calculated. The results are compared with the foregone consumption due to the delayed next step of the tax reform. On balance clear effects can be observed in construction.

Prospects for 2002: Waiting for the cyclical change
Wirtschaft im Wandel,
No. 1,
2002
Abstract
This article updates the complete analysis and forecast of the economic developments in the World and Germany in particular for 2002, as published in Summer. After six quarters of downturn, the beginning of 2002 does not show signs of a revival in economic activity. Neither internal nor external forces are currently strong enough to reverse the underlying downward trend. It is assumed that by spring time the recession in the USA will have faded. Resulting is a stimulus for the World Economy. This initiating impulse will revive production in Germany and the Euro Area, which by the second half of 2002 will gain pace. The increase in exports, as induced by the upturn in the US-Economy will positively affect domestic demand. With the usual time lag this development will also strengthen the job market. Monetary Policy will remain expansive and begins to show its full effect. Fiscal Policy, on the other hand, due to the need for consolidation, will remain restrictive.

Moderate production and employment effects through rising crude oil prices – A simulation with the macroeconomic IWH model –
Christian Dreger
Wirtschaft im Wandel,
No. 15,
2000
Abstract
In the article the impacts of a rise in oil prices on production and employment are examined. The impacts are carried out by simulation on the grounds of a macroeconometric model. Given various price developments, the effects on production and employment are less pronounced than those in previous crisis. In the worst case scenario, output losses are 0.4 percentage points of the overall growth rate of the economy.
