The Positive Economics of Labor Market Rigidities and Investor Protection

This paper presents a positive model which shows that institutional setups on capital and labor markets might be intertwined by politicoeconomic forces. Some countries especially in continental Europe exhibit a corporatist politicoeconomic equilibrium with a substantial protection of insiders on both markets. The more important money is in political decision-making, the more divided the workforce is, and the more globalized capital markets are, the more likely is a capitalist politicoeconomic equilibrium with little employment and substantial investor protection. Our prediction of a negative cross-country relationship between labor market rigidities and of competition on capital markets receives considerable empirical support.Labor markets, employment protection, corporatism, corporate governance, shareholder protection, political economy

The positive economics of corporatism and corporate governance

This paper presents a positive model which shows that institutional setups on capital and labor markets might be intertwined by politicoeconomic forces. Two politicoeconomic equilibria arise from our model, one with little protection of insiders on capital and labor markets, and another one with an institutional bias toward favoring insiders on both markets. Coherent and relatively homogeneous societies, where binding commitments enjoy greater feasability, are more likely to be found in the latter, corporatist equilibrium, whereas fragmented, heterogeneous Anglo-Saxon societies fit better into the former category. These predictions of the model receive considerable support in our crosscountry empirical analysis, thus being potentially important for the current debates concerning the reforms of labor markets and of corporate governance systems. --

Did the Bundesbank Follow a Taylor Rule? An Analysis Based on Real-Time Data

Using a real-time data set for German GDP over the period from 1973 to 1998 we calculate various measures of real-time output gaps and use these to calibrate and estimate Taylor-type reaction functions for the Bundesbank. Most of the reaction functions we find fit the Bundesbank´s actual policy, as represented by the short-run interest rate, quite well. In contrast to previous findings based on ex post revised data for the output gap, we find the reaction coefficients to resemble quite closely those originally proposed by Taylor for some of our real-time measures of the output gap. Broad monetary aggregates such as M3, in contrast, only played a small role for the Bundesbank´s interest rate decisions. Given the good record of the Bundesbank in fighting inflation, the results give support for the use of the Taylor rule for monetary policy.German real-time data; output gap; monetary policy rules

Euroland: Strong upswing, risks to price level stability

The Euroland economy is in a strong upswing. Last year, real GDP increased at a rate roughly equal to that of potential output in spite of the export losses in the wake of the crises in various countries of the world. There have been considerable impulses from monetary policy. Because of the strength of the economy, the ECB has started to tighten its policy. Nevertheless, monetary conditions in the euro area are still favorable. In 2000, real GDP is likely to increase by 3.2 percent; this is the highest rate in the past ten years. After a weak start, the economy gained considerable momentum in the course of 1999. While the strong export performance was responsible for the turnaround, domestic demand growth also accelerated somewhat. In the second half of 1999, real GDP increased at an annual rate of 3.5 percent, and capacity utilization should have reached its normal level by now. Inflation picked up in the course of 1999 with rates between 1.5 and 2.0 percent, thus coming close to the upper limit of the target range tolerated by the ECB. The driving force so far were higher import prices. Since November, the ECB has raised key interest rates by 100 basis points to 3.50 percent. This is the first tightening of monetary policy since the fall of 1997. The expansion of M3, however, indicates that monetary policy continues to be expansionary. Last year, the reference value for money growth was exceeded considerably. The interest rate hikes must be seen against this background. They were the logical consequence in the concept which is based on money growth. In the present situation, rules for monetary policy also suggest a tightening. The McCallum Rule pertains to the growth rate of the money stock M3 that is compatible with the inflation target and the trend changes in output and velocity. Since early 1999, money growth has been higher than the rate implied by the rule. If this tendency continued, inflation would exceed 2 percent. In order to avoid this, interest rates have to go up. Similarly, the Taylor Rule suggests that interest rates need to be higher because capacity utilization is at its normal level and will rise further. The countries in the euro area have come closer to the target of the Stability and Growth Pact as budget deficits have declined. Next year, fiscal policy will be characterized by tax cuts in a number of countries. The strongest impulse will come from the tax reform in Germany. For Euroland as a whole, the stance of fiscal policy will thus become expansionary. In general, there appears to be a shift in the strategy of fiscal policy: While deficits were reduced on the road to EMU also by increases in taxes and contributions, the revenue/GDP ratio will decline in the coming three years according to the plans of governments. Spending is supposed to decline even more so that deficits will shrink. Such a strategy can be highly recommended. According to empirical estimates, fiscal policy has contributed to the decline in the potential growth rate in the past 30 years by expanding the share of government spending in GDP. While leading indicators point to a strong expansion of economic activity in the near future, several factors will lead to a moderate slowdown of the upswing later this year and in 2001. The recovery in the world economy will lose some momentum and the effect of the weaker euro will gradually fade. Furthermore, the ECB will raise interest rates again. An impulse for the upswing, however, will result from the turnaround of fiscal policy. All in all, real GDP growth will amount to 3.2 percent this year and will go down to 2.8 percent in 2001. The unemployment rate will continue to fall; next year, it'will drop to below 9 percent for the first time since 1992. Consumer prices will rise a lot faster than in 1999. Although the inflation rate will decline somewhat in the course of this year because import prices will moderate, the core rate of inflation will go up due to the marked rise in capacity utilization. The Harmonized Index of Consumer Prices will increase by 1.9 percent this year and by 1.8 percent next year. The weakness of the euro has a stimulating effect on output in the euro area which is equivalent to roughly half a percentage point of GDP. If the trade links of the individual EMU countries with the dollar area are taken into account, it can be shown that the effects are spread more or less symmetrically across the economies. --

Deutlicher Anstieg der Nettozuwanderung nach Deutschland

Die Nettozuwanderung nach Deutschland nimmt seit 2010 deutlich zu. Der maßgebliche Faktor hierfür dürfte die konjunkturelle Sondersituation in Europa sein, die sich durch einen Arbeitsmarktboom in Deutschland und eine stark gestiegene Arbeitslosigkeit in anderen Teilen Europas auszeichnet. Wanderungssalden in der aktuellen Größenordnung sind gesamtwirtschaftlich relevant, sie erhöhen das Produktionspotenzial, dämpfen den Lohn- und Preisauftrieb und haben möglicherweise Auswirkungen auf die Sozialversicherungen.Since 2010 net immigration to Germany has risen significantly. Net immigration to Germany in 2012 is estimated to total nearly 400 000 people. Influxes of such a magnitude have significant macroeconomic implications. While in the long run they increase the domestic labour force and hence potential output, they moderate wages and prices in the short run. This article investigates the determinants of immigration to Germany and its outlook for the coming years. It shows that differences in employment opportunities in Germany and in the rest of Europe largely explain migration fl ows. Owing to Germany's attractive labour market and the expected slow recovery in neighbouring Europe, cumulative immigration to Germany is likely to exceed two million by 2017

Trend und Zyklus im Bruttoinlandsprodukt der Bundesrepublik Deutschland - eine Anmerkung

This note shows that German real GDP follows a trend-stationary process. Both tests which have trend-stationarity as the alternative hypothesis as well as tests that have it under the null hypothesis prefer the trend-stationary model. Explicit consideration of breaks in the trend is not necessary to obtain this result. The trend-stationary model with breaks is, however, advantageous for trend-cycle decompositions.Diese Anmerkung zeigt, dass das reale Bruttoinlandsprodukt der Bundesrepublik Deutschland einem trendstationären Prozess folgt. Dabei werden sowohl ökonometrische Tests, bei denen die Trendstationarität die Alternativhypothese ist, eingesetzt als auch solche, bei denen sie die Nullhypothese darstellt. Beide Verfahren präferieren das trendstationäre Modell. Eine explizite Berücksichtigung von Brüchen im Trend ist für dieses Ergebnis nicht notwendig. Für die praktische Trend-Zyklus-Zerlegung im Rahmen der Konjunkturforschung hat ein Modell mit Trendbrüchen gleichwohl Vorteile
