Productivity in German Manufacturing Firms: Does Fixed-Term Employment Matter?

A growing proportion of employees are working under fixed-term contracts. This paper empirically analyzes whether this strategy actually improves firm productivity. To this end, a largedata set of German manufacturing firms and various panel data models are used in order to reveal the expected non-linear effect. Thereby the analysis also takes into account distortions that may result from...

Success and Failure in Strategic Alliances: Theory and Experimental Evidence

This paper proposes a theoretical framework of strategic alliances that includes two observable dimensions of participating partners which have been identified in the literature as critical for success or failure. In particular, we first propose a simple static theory that links the degree of alliance partners' complementarities with the intensity of their competition in product markets. We show...

Hidden Skewness: On the Difficulty of Multiplicative Compounding under Random Shocks

Multiplicative growth processes that are subject to random shocks often have a skewed distribution of outcomes. In a number of incentivized laboratory experiments we show that a large majority of participants either strongly underestimate skewness or ignore it completely. Participants misperceive the outcome distribution's spread to be far too narrow-band and they estimate the median to lie too...

Confidence Bands for Impulse Responses: Bonferroni versus Wald

It is emphasized that the shocks in structural vector autoregressions are only identified up to sign and it is pointed out that this feature can result in very misleading confidence intervals for impulse responses if simulation methods such as Bayesian or bootstrap methods are used. The confidence intervals heavily depend on which variable is used for fixing the sign of the initial responses. In...

Analyzing Economic Policies that Affect Supply and Demand: A Structural Model of Productivity, Labor Supply and Rationing

In this paper a labor supply model with demand side rationing is estimated to analyze the economic policies that directly affect incentives to work as well as labor costs. The framework is applied to evaluate the employment effects of a federal minimum wage in Germany and the impact of employervs. employee-oriented wage subsidies under a statutory minimum. We extend Laroque and Salanié (2002) by...

Natural Disaster, Policy Action, and Mental Well-Being: The Case of Fukushima

We study the impact of the Fukushima disaster on people's mental well-being in another industrialized country, more than 5000 miles distant. The meltdown significantly increased environmental concerns by 20% among the German population. Subsequent drastic policy action permanently shut down the oldest nuclear reactors, implemented the phase-out of the remaining ones, and proclaimed the transition...

Comparison of Feed-in Tariffs and Tenders to Remunerate Solar Power Generation

This paper analyzes the trade-offs for using feed-in tariffs or tenders to remunerate different scales of solar photovoltaics (PV) projects. In recent years, European . - countries increasingly combined feed-in tariffs for small renewables systems with tenders for large installations. This study develops an analytic framework to quantify . - deployment effectiveness of responsive feed-in tariff...

Optimal Unemployment Insurance and Welfare Benefits in a Life-Cycle Model of Family Labor Supply and Savings

We specify and estimate a dynamic structural life-cycle model of labor supply, retirement and savings decisions of single-adult and couple households. Drawing on our model, we study the interplay between family labor supply and public insurance mechanisms. By including family labor supply, we recognize that the incentive effects and optimal design of publicinsurance programs may be impacted by a...

Adverse Effects of Increased Education Efficiency? The Impact of Shortening High School Tenure on Graduation Age, Grade Repetitions and Graduation Rates

In designing education systems, policy-makers face a trade-off between the provision of higher levels of schooling and earlier labour market entries. A fundamental education reform in Germany tackles this trade-off by increasing education efficiency: The time in high school is reduced by one year while the total number of instruction hours is left unchanged. Employing administrative data on all...

The Introduction of Disincentives for Early Retirement and Its Effect on Labor Market Participation

We evaluate the actual effectiveness of disincentives that have been introduced for early retirement in Germany. Therefore, we set up a detailed model of the German social security and tax system with special attention to the PAYG-pension system. Building on the fact that the institutional changes were phased in, impacting birth cohorts to a different degree we are able to estimate the parameters...
