Employing data from a representative survey conducted in Germany, this paper examines public preferences for the size and composition of government expenditure. We focus on public attitudes towards taxes, public debt incurrence and public spending in six different policy areas. Our findings suggest, first, that individual preferences for the use of additional tax money can be categorised as either capital-oriented expenditure or public debt reduction. Second, we find that fiscal preferences differ along various dimensions. Specifically, personal economic well-being, economic literacy, confidence in politicians, political ideology and time preference are significantly related to individual attitudes towards public spending, taxes and debt. The magnitude of the effects is particularly large for time preference, economic knowledge and party preference. Third, public preferences for public spending priorities are only marginally affected when considering a public budget constraint.

The rise of early retirement in Europe is typically attributed to the European system of taxes and transfers. A model with an imperfectly competitive labor market allows us to consider also the effects of bargaining power and of matching efficiency on pre-retirement. We find that lower bargaining power of workers and declining matching efficiency have been important determinants of early retirement in France and Germany. These structural changes, combined with early retirement transfers and population aging, are also consistent with the employment and unemployment rates, labor share and seniority premia.

We investigate how changes in the composition of tax revenue affect long-run growth in a broad cross-section of countries. To do this, we construct a new dataset that covers 70 countries (23 high-, 23 middle- and 24 low-income countries), with at least 20 years of observations during the period 1970-2009. In the context of revenue-neutral reallocations, we find that increasing consumption and property taxes while reducing income taxes boosts long-term growth. Among income taxes, we find that social security contributions and personal income taxes tend to have a stronger negative association with growth relative to corporate income taxes. Results, however, depend on countries’ development levels, suggesting nonlinearities in the relation between taxes and growth even after controlling for convergence effects. Although results are robust for high- and middle-income countries, these are generally not significant for low-income countries.

This study investigates the direct incidence of the corporate income tax (CIT) through wage bargaining, using an industry-region level panel dataset on all corporations in Germany over the period 1998-2006. For the first time we account for employment effects which result from tax-induced wage changes. Workers share in reductions of the CIT burden; yet, the net effect of wage bargaining on the corporate wage bill, after an exogenous €1 decrease in the CIT burden, is as little as 19-28 cents. This is about half of the effect obtained in prior literature focussing on wages alone.

This paper updates and deepens our understanding of the wage performance of immigrants in Germany. Using the German Socio-Economic Panel, it documents that immigrant workers initially earn on average 20% less than native workers with otherwise identical characteristics. The gap is smaller for immigrants from advanced countries, with good German language skills, and with a German degree, and larger for others. The gap declines gradually over time but at a decreasing rate and much faster for more recent cohorts. Less success in obtaining jobs with higher occupational autonomy explains half of the wage gap.

Most German states have recently reduced the duration of university preparatory schooling from 13 to 12 years without changing the graduation requirements. We use nationwide data on high school graduates and the different timing of reform introduction in the federal states to identify the effects on post-secondary education decisions and to evaluate potential effect mechanisms. The results show that university enrolment of female students decreased in the first year after graduation in all analyzed states, whereas participation in voluntary service or staying abroad increased. Furthermore, students from non-academic families are more affected than students from an academic family background.

In this paper, we investigate whether differences exist among forecasts using real-time or latest-available data to predict gross domestic product (GDP). We employ mixed-frequency models and real-time data to reassess the role of surveys and financial data relative to industrial production and orders in Germany. Although we find evidence that forecast characteristics based on real-time and final data releases differ, we also observe minimal impacts on the relative forecasting performance of indicator models. However, when obtaining the optimal combination of soft and hard data, the use of final release data may understate the role of survey information.

We present empirical evidence suggesting that technological progress in the digital age will be biased not only with respect to skills acquired through education but additionally with respect to non-cognitive skills (personality). We measure the direction of technological change by estimated future digitalization probabilities of occupations, and non-cognitive skills by the Big Five personality traits from four German worker surveys. Even though we control for education and work experience, we find that workers who are more open to experience, emotionally more stable and less agreeable will tend to be less susceptible to digitalization. We also find that future technological progress may not continue to hollow out the middle class as much as it did in the recent past. These results suggest that education and labor market policies should put more emphasis on children’s and workers’ personalities to strengthen their labor market resilience in the digital age.

This study provides novel evidence on the relevance of task content changes between and within occupations to wage dynamics of occupational changers and stayers. I use individual-level, cross-sectional data featuring tasks performed on the job to compute a measure of proximity of job contents. Then, I merge this measure to a large-scale panel survey to show that occupational changers experience a wage growth that is declining when the accompanying alterations in task contents are big. For occupational stayers, alterations in task contents generate a positive wage component, beyond tenure effect. However, the results are not robust with respect to the choice of proximity measure and over time.

This paper analyzes the gender wage gap across the wage distribution using 2010 data from the German Statistical Agency. I investigate East and West Germany and the public sector separately to account for potential heterogeneities in wage gaps. I apply unconditional and conditional quantile regression methods to investigate the differences between highly paid men and women in distributions conditional and unconditional on covariates. The results indicate increasing gender wage gaps in all estimations, suggesting that there is indeed a glass ceiling over Germany even after controlling for a large set of observable characteristics (including occupation and industry). This finding is even more pronounced when also taking bonus payments into account.

Using an estimated large-scale New Keynesian model, we assess the consequences of introducing a fiscal union within EMU. We differentiate between three different scenarios: public revenue equalisation, tax harmonisation and a centralised fiscal authority. Our results indicate that no country would significantly benefit from introducing any form of fiscal union. Comparing long-term, that is, steady state, effects we have winners and losers depending on the scenario. Differences in terms of business cycle statistics as well as in terms of risk sharing of asymmetric shocks are minor. This also explains why welfare differences are small across the fiscal union scenarios. A counterfactual exercise indicates that with a fiscal union regime already installed at the start of EMU, key macroeconomic variables would have reacted very similarly while debt dynamics would have changed notably.

This study analyzes the efficiency of the road production by local governments using data envelopment analysis. The production of roads is a costly public service, which makes an efficiency analysis in this field an interesting subject. I enhance the previous literature, first, by examining the differences in the efficiencies of eastern German counties while considering the deformation of the pavement and foundation of roads, which previous studies have not included due to data limitations. Second, I use a unique dataset on road quality for my efficiency analysis and show that the efficiency levels differ from those in studies that apply proxies, such as the number of accidents, to capture the quality of roads. These findings indicate that there is a great need to develop reliable variables to describe government services. Additionally, I show that the correlations between efficiency levels and county characteristics vary greatly depending on the quality indicator used.

Since the mid-1990s interregional migration flows in Italy have dramatically increased, especially from the South to the North. These flows are characterized by a strong component of human capital, involving a large number of workers with secondary and tertiary education. Using longitudinal data for the period 2002-2011 at NUTS-3 territorial level, we document that long-distance (i.e., South-North) net migration of high-skill workers has increased the unemployment at origin and decreased it at destination, thus deepening North-South unemployment disparities. On the other hand, long-distance net migration of low-skill workers has had the opposite effect, by lowering the unemployment at origin and raising it at destination. Further evidence also suggests that the diverging effect of high-skill migration dominates the converging effect of lowskill migration. Thus, concerns for an ‘internal brain drain’ from Southern regions look not groundless.

This paper extends the literature on predatory short selling and bailouts through a joint analysis of the two. We consider a model with informed short sales, as well as uninformed predatory short sales, which can trigger the inefficient liquidation of a firm. We obtain several novel results: A government commitment to bail out insolvent firms with positive probability can increase welfare because it selectively deters predatory short selling without hampering desirable informed short sales. Contrasting a common view, bailouts can be optimal ex ante but undesirable ex post. Furthermore, bailouts in our model are a better policy tool than short selling restrictions. Welfare gains from the bailout policy are unevenly distributed: shareholders gain while taxpayers lose. Bailout taxes allow ex ante Pareto improvements.

Intensified counseling, job search assistance and related policies have been found to be effective for labor market integration of the unemployed by a large number of studies, but the evidence for older and hard-to-place unemployed is more mixed. In this paper, we present key results for a large-scale active labor market program directed at the older unemployed in Germany. To identify the treatment effects, we exploit regional variation in program participation. We use a combination of different evaluation estimators to check the sensitivity of the results to selection, substitution and local labor market effects. We find positive effects of the program in the range of 5-10 percentage points on integration into unsubsidized employment. However, there are also substantial lock-in effects, such that program participants have a higher probability of remaining on public welfare benefit receipt for up to 1 year after commencing the program.

We analyze the effect of worker inflows on establishments’ productivity, using German data. Previous studies for other countries have found positive effects of hiring workers from superior (more productive or higher paying) firms. Ranking establishments by their median wage, we find that inflows from inferior establishments seem to increase hiring establishments’ productivity. Further empirical analyses suggest our findings are due to a positive selection of such inflows from their sending establishments. These workers might have to find a better job match in order to advance their careers, an interpretation supported by the finding that the effect is driven by workers with short tenure at their previous employer. Our findings reflect the increasingly assortative pattern of worker mobility in Germany found in a related strand of literature.

This paper extends the green paradox literature by providing empirical insights into its existence. To check the green paradox theory, I analyse the production of coal in four major coal-producing US states that announced a greenhouse gas action plan. To form a statement on whether there is a treatment effect caused by the green policy, I employ Synthetic Control Methods to calculate counterfactual coal production trajectories. I find that Montana experienced a high and statistically significant increase in coal production that is supported by a set of validity indicators. However, there is no evidence for a paradox in Kentucky, Pennsylvania and Virginia.

Several studies have analyzed motives to work in the public versus private sector. However, research on prosocial motivation in the context of public sector employment has largely neglected civic virtue, the motive to contribute to society. This study considers civic virtue in addition to other possible motives, using a representative, longitudinal dataset of employees in Germany including 63,180 observations of 13,683 different individuals. We find that civic virtue relates positively to public sector employment beyond altruism, risk aversion, laziness and (low) financial motivation. The result holds within different branches and is explained by sorting into the sector.

Cyber technology represents digital military capability with the purpose of causing damage to the military strength of a potential enemy. War using conventional weapons may be preceded by a strike using cyber technology. This paper introduces such technology into the theory of conflicts. The cost of war relative to the payoff from victory turns out to be crucial for the results on armament decisions. In the war game, two types of Nash equilibria may arise. One is subject to warfare while the other is not (‘equilibrium of terror’), depending on the perceived cost of war. In a symmetric war game, cyber capabilities are neutral with respect to the investments in conventional weapons, but they make wars more likely. Asymmetric access to cyber technology limits the international arms race with conventional weapons. A low success probability in the cyber programme encourages exercising the cyberattack option as the enemy may not have access to cyber capability. Uncertainty of the success of a cyber programme makes countries cautious when allocating resources not only to these programmes but also in conventional armament.

We provide evidence on the effect of elementary index choice on inflation measurement in the euro area. Using scanner data for 15,844 individual items from 42 product categories and 10 euro area countries, we compute product category level elementary price indexes using eight different elementary index formulas. Measured inflation outcomes of the different index formulas are compared with the Fisher ideal index to quantify elementary index bias. We have three main findings. First, elementary index bias is quite variable across product categories, countries and index formulas. Second, a comparison of elementary index formulas with and without expenditure weights shows that a shift from price only indexes to expenditure weighted indexes would entail at the product level multiple percentage points differences in measured price changes. And finally, we show that elementary index bias is quantitatively more important than upper level substitution bias.

We examine whether conservative politicians are less likely to support same-sex marriage when they run for office in safe rather than in contested districts using new data based on a roll-call vote in the national German parliament. The results show that the margin of the majority for the incumbent in the previous election was a strong predictor for supporting same-sex marriage. When the majority increased by a 1 percentage point, the likelihood of voting in favour of same-sex marriage decreased by around 1.3 percentage points. We conjecture that politicians are election-motivated - even when submitting roll-call votes on a matter of conscience.

From 2014 until present, housing prices in Germany have been rising faster than consumer prices in all quarters except one, raising concerns about an excessive overheating of the housing market. To assess the vulnerability of the German housing market to a future realignment of prices or even a housing bust, this paper develops a housing price misalignment indicator that is composed of seven indicators, which are commonly associated with the fundamental value of residential property. An empirical application to the most recent data suggests that the German housing market exhibits an overvaluation of approximately 11%, where interest rate risk and a relatively advanced stage of the housing cycle are identified as the main factors fueling these imbalances, while a rather solid debt-servicing capacity mitigates these imbalances since end-2009.

This paper discusses the advantages of Epstein and Zin (1989) (EZ) preferences when building dynamic stochastic general equilibrium (DSGE) models that are consistent with well-known stylized facts of both the business cycle and asset markets. To this end, we combine EZ preferences with several building blocks from the DSGE literature that has tried to solve the equity premium puzzle and to replicate characteristic statistics of the labor market. Our goal is to guide researchers in this area to useful modeling devices and to discuss EZ preferences vis-a-vis the standard time-additive expected utility function. EZ preferences separate the attitude toward risk from the attitude toward intertemporal substitution. We demonstrate that this additional degree of freedom allows us to closely match the empirical facts already in a frictionless production economy with endogenous labor supply. Our study follows Heer and Maußner (2013). We examine models that consider adjustment costs of capital accumulation, consumption habits, and frictions in the allocation of labor. Our empirical targets are estimated from German data.

Based on a novel dataset, the ‘German Management and Organizational Practices’ (GMOP) Survey, we calculate establishment-specific management scores following Bloom and van Reenen as indicators of management quality. We find substantial heterogeneity in management practices across establishments in Germany, with small establishments having lower scores than large establishments on average. We show a robust positive and economically important association between the management score and establishment level productivity in Germany. This association increases with establishment size. Comparison to a similar survey in the United States indicates that the average management score is lower in Germany than in the United States. Overall, our results point toward lower management quality being at least in part to blame for the differences in aggregate productivity between Germany and the United States.

We investigate the effect of spells of no formal employment of young Germans on their chances of entering the labor market through an apprenticeship. We also study whether the potential negative effects of such spells can be mitigated by publicly provided training measures. In a field experiment, the fictitious applications of three young women were sent to firms advertising apprenticeships for the position of office manager. One application was from a fresh school-leaver and two from applicants who had been out of school for two years, where one of them had participated in a training measure. We find that applicants who have been out of school for two years and have participated in the training are more successful than older applicants without additional training. We do not find a significant difference between older applicants with or without training and fresh school leavers. Our findings show that training measures increase the attractiveness of applicants and that the potential stigma of spells of no formal employment after school are compensated by informal work experience or age or a combination of both.

This research develops a tractable two-stage non-cooperative game with complete information describing the behaviour of price-setting firms that must choose to be profit maximisers or bargainers under codetermination in a network industry with horizontal product differentiation. The existing theoretical literature has already shown that codetermination might arise as the endogenous market outcome in a strategic competitive quantity-setting duopoly. In sharp contrast with this result, the present article shows that codetermination does never emerge as a Nash equilibrium in a price-setting non-network duopoly. Then, it aims at highlighting the role of network externalities in determining changes of paradigm of the game and letting codetermination become a sub-game perfect Nash equilibrium when prices are strategic substitutes or strategic complements. This equilibrium may be Pareto efficient. Results allow distinguishing between mandatory codetermination and voluntary codetermination. The article also proposes a model of endogenous codetermination according to which every firm may choose to bargain with its own corresponding union bargaining unit only whether the firm’s bargaining strength is exactly the profit-maximising one. The equilibrium outcomes emerging in this case range from a uniform Nash equilibrium, in which both firms are codetermined, to mixed Nash equilibria, in which only one of them chooses to be codetermined. These results are ‘network depending’ and do not hold in a non-network duopoly.

In absence of randomized-controlled experiments, identification is often aimed via instrumental variable (IV) strategies, typically two-stage least squares estimations. According to Bayes’ rule, however, under a low ex ante probability that a hypothesis is true (e.g. that an excluded instrument is partially correlated with an endogenous regressor), the interpretation of the estimation results may be fundamentally flawed. This paper argues that rigorous theoretical reasoning is key to design credible identification strategies, the foremost, finding candidates for valid instruments. We discuss prominent IV analyses from the macro-development literature to illustrate the potential benefit of structurally derived IV approaches.

The role of inherited wealth in modern economies has increasingly come under scrutiny. This study presents one of the first attempts to shed light on how demographic aging could shape this role. It shows that, in the absence of retirement annuities, or for a given level of annuitization, both increasing longevity and decreasing fertility should reduce the inherited share of total wealth in a given economy. Thus, aging is not likely to explain a recent surge in this share in some advanced economies. Shrinking retirement annuities, however, could offset and potentially reverse these effects. The paper also shows that individual bequests will be more unequally distributed if aging is driven by a drop in fertility. In comparison, the effect of increasing longevity on their distribution is non-monotonic.

I analyze the competition among different countries for ‘desirable’ and ‘undesirable’ potential immigrants, using both an immigration quota and a level of (imperfect) ‘scrutiny’ that would-be immigrants face. Scrutiny imposes costs on immigrants and therefore makes it less attractive to immigrate. The number of applying undesirable immigrants increases in immigration quota and decreases in the level of scrutiny. In contrast, the number of desirable applicants can go in either direction as scrutiny increases and is independent of the immigration quota, because an increase in the immigration quota is completely crowded out by more applications by undesirable immigrants.

New rental contracts have risen dramatically in many German places in recent years due to strong influxes and sluggish construction activity. The rent brake should put a stop to this development so that housing in prospering cities remains affordable for people on normal and low incomes. Although initial successes were attested to the rent brake, empirical findings are increasing, according to which the rent brake is not having the desired effect. This also applies to the findings determined here: the results of a difference-in-difference estimation show that the rent brake has reduced rents on offer in Hamburg, Berlin and Munich by up to 5%, while no effects are observed in Cologne and Düsseldorf. Nevertheless, the effects are lagging behind the expected effects almost everywhere. The results illustrate once again an implementation deficit and show that no general statements on the effectiveness of the rent brake are currently permissible. However, the rent brake is certainly having a price effect in some regions, even if not to the intended extent.

This paper integrates into public economics a biologically founded, stochastic process of individual aging. The novel approach enables us to quantitatively characterize the optimal joint design of health and retirement policy behind the veil of ignorance for today and in response to future medical progress. Calibrating our model to Germany, our analysis suggests that the current social insurance policy instruments are set close to the (constrained) socially optimal levels, given proportional contribution rates for health and pension finance, the equivalence principle in the pension system, and a common statutory retirement age. Future progress in medical technology calls for a potentially drastic increase in health spending and a higher retirement age without lowering the pension contribution rate. Interestingly, from an ex ante point of view, medical progress and higher health spending are in conflict with the goal to reduce health inequality.

People typically set goals in settings where they cannot be sure of how they will perform, but where their performance is revealed to them in parts over time. When part of the uncertainty is resolved, initial goals may have turned out to be unrealistic and hence they no longer work as a motivation device. Revising goals may increase performance by making goals realistic, but may also adversely affect performance through reduced goal commitment. We study the effects of motivating university students to set goals and inviting them to revise their goals later, using a field experiment involving nearly 2,100 students. We use courses containing two midterms and a final exam, where midterms reduce uncertainty about students’ potential performance. We find that motivating students to set goals does not affect performance on average. Students with midterm grades lower than their goal, decrease their performance. This effect is driven by students who were motivated to set goals without being made aware that they can revise their goals later. This finding may help explain why the evidence of the effectiveness of goals on study performance is mixed.

Forward guidance can be provided as an unconditional promise, i.e. commitment to a specific low policy rate. Alternatively, the promise may include an escape clause, i.e. a condition defining the state of the economy under which the central bank would not keep such a low rate and, instead, it would revert to setting policy under discretion. The escape clause can be expressed as a threshold in terms of a specific variable. The present paper shows that, when such a threshold is expressed in terms of an endogenous variable (e.g. output, inflation), there are cases where it becomes impossible for the central bank to act in a way that is consistent with its promise. Consistency imposes limits on the policy rate that can be set since reverting immediately to the optimal discretionary rate can be incompatible with exceeding the threshold.

After the seminal work of Nickell (1981), a vast literature demonstrates the inconsistency of ‘conditional convergence’ estimator in income-based dynamic panel models with fixed effects when the time horizon (T) is short but the sample of countries (N) is large. Less attention is given to the economic root of inconsistency of the fixed effects estimator when T is also large. Using a variant of the Ramsey growth model with long-run adjustment cost of capital, we demonstrate that the fixed effects estimator of such models could be inconsistent when T is large. This inconsistency arises because of the long-run adjustment cost of capital which gives rise to a negative moving average coefficient in the error term. Income convergence will be thus overestimated. We theoretically characterize the order of this inconsistency. Our Monte Carlo simulation demonstrates that the size of the bias is substantial and it is greater in economies with higher capital adjustment costs. We show that the use of instrumental variables that take into account the presence of the negative moving average term in the error will overcome this bias.

Using a standard New Keynesian model, we show that moderate side effects of zero lower bound (ZLB) policy suffice for positive lower bound (PLB) policy to pay off in terms of welfare, especially when central banks fail to commit. For given side effects of the ZLB, as the shock that makes the ZLB bind becomes larger and more persistent, the dominance of PLB policy over ZLB policy becomes more likely. The findings hold for flexible and rigid economies with both fast and slow potential output growth and low and high inflation targets.

This paper investigates the impact of monetary incentives on whole blood donations. We take advantage of a quasi-natural experiment in Germany, in which one blood donation site changes its payment scheme from remunerated to non-remunerated. All other donation sites maintain their payment schemes. We show that donation volumes drop significantly after the pay drop and do not recuperate. At the same time, donation volumes increase at other paid donation sites, which is partly due to donor migration to these sites. We do not find any impact of the changed payment scheme on blood quality. Our results offer additional insight into the complex question whether it is efficient to ensure blood supply by paying donors a direct monetary compensation.

How do physical capital accumulation and total factor productivity (TFP) individually add to economic growth? We approach this question from the perspective of the quality of physical capital and labor, namely the age of physical capital and human capital. We build a unique dataset by explicitly calculating the age of physical capital for each country and each year of our time frame and estimate a stochastic frontier production function incorporating input quality in five regions of countries (Africa, East Asia, Latin America, South Asia and West). Physical capital accumulation generally proves much more important than either the improved quality of factors or TFP growth in explaining output growth. The age of capital decreases growth in all regions except in Africa, while human capital increases growth in all regions except in East Asia.

We construct long-run sustainability indicators based on changes in Comprehensive Wealth - which we refer to as Genuine Savings (GS) - for Germany over the period 1850-2000. We find that German sustainability indicators are positive for the most part, although they are negative during and after the two World Wars and also the Great Depression. We also test the relationship between these wealth changes and a number of measures of well-being over the long-run: changes in consumption as well as changes in average height and infant mortality rates. We find a positive relationship between GS and our well-being indicators over different time horizons, however, the relationship breaks down during WWII. We also test if the GS/Comprehensive Wealth framework is able to cope with massive disinvestment at the end of the Second World War due to war-related destructions and dismantlement. We find that negative rates of GS were by and large avoided due to the accumulation of technology and growth-friendly institutions. We demonstrate the importance of broader measures of capital, including measures of technological progress, and its role in the process of economic development; and the limits of conventional measures of investment to understand why future German consumption did not collapse.

In this paper, we investigate US monetary policy and its time-varying effects over more than 130 years. For that purpose, we use a Bayesian time-varying parameter vector autoregression that features modern shrinkage priors and stochastic volatility. Our results can be summarized as follows: First, we find that monetary policy transmits jointly through the interest rate, credit/bank lending and wealth channels. Second, we find evidence for changes of both responses to a monetary policy shock and volatility characterizing the macroeconomic environment. Effects on the macroeconomy are significantly lower in the period from 1960 to 2013 than in the early part of our sample, whereas responses of short- and long-term interest rates are nearly unaltered throughout the sample. Changes in the way the Fed conducts monetary policy and different economic environments may account for that.

While income inequality in Germany considerably increased in the years before 2005, this trend stopped after 2005. We address the question of what factors were responsible for the break in the inequality trend after 2005. Our analysis suggests that income inequality in Germany did not continue to rise after 2005 for the following reasons. First, we observe that the general rise in wage inequality that explained a lot of the inequality increase before 2005, became less steep (but did not stop) after 2005. Second, despite further increases in wage inequality after 2005, inequality in annual labour incomes did not increase further after 2005 because increased within-year employment opportunities compensated otherwise rising inequality in annual labour incomes. Third, income inequality did not fall in a more marked way after 2005 because also the middle and the upper part of the distribution benefited from the employment boom after 2006. Finally, we provide evidence that the effect of a wide range of other factors that are often suspected to have influenced the distribution such as capital incomes, household structures, population ageing, changes in the tax and transfer system and the financial crisis of 2008 did not significantly alter the distribution after 2005.
