IZA Discussion Paper,
No. 13267,

Abstract
We show, theoretically and empirically, that the effects of technological change associated with automation and offshoring on the labor market can substantially deviate from standard neoclassical conclusions when search frictions hinder efficient assortative matching between firms with heterogeneous tasks and workers with heterogeneous skills. Our key hypothesis is that better matches enjoy a comparative advantage in exploiting automation and a comparative disadvantage in exploiting offshoring. It implies that automation (offshoring) may reduce (raise) employment by lengthening (shortening) unemployment duration due to higher (lower) match selectivity. We find empirical support for this implication in a dataset covering 92 occupations and 16 sectors in 13 European countries from 1995 to 2010.

Tornado Activity, House Price and Stock Returns

North American Journal of Economics and Finance,

2020
Abstract
In this paper we investigate the effects of tornado activity on house prices and stock returns in the US. First, using geo-referenced and metropolitan statistical area (MSA)-level data, we find tornado activity to be responsible for a significant drop in house prices. Spillover tornado effects between adjacent MSAs are also detected. Furthermore, our granular analysis provides evidence of tornadoes having a negative impact on stock returns. However, only two sectors seem to contribute to such a negative effect (i.e., consumer discretionary and telecommunications). In a macro-analysis, which relies on aggregate data for the South, West, Midwest and Northeast US regions, we then show that tornado activity generates a significant drop in house prices only in the South and Midwest. In these regions, tornadoes are also responsible for a drop in income. Tornado activity is finally found to positively (negatively) affect stock returns in the Midwest (South). If different sectors are examined, a more heterogeneous picture emerges.

flexpaneldid: A Stata Toolbox for Causal Analysis with Varying Treatment Time and Duration
Eva Dettmann, Alexander Giebler, Antje Weyh
IWH Discussion Papers,
No. 3,
2020
Abstract
The paper presents a modification of the matching and difference-in-differences approach of Heckman et al. (1998) for the staggered treatment adoption design and a Stata tool that implements the approach. This flexible conditional difference-in-differences approach is particularly useful for causal analysis of treatments with varying start dates and varying treatment durations. Introducing more flexibility enables the user to consider individual treatment periods for the treated observations and thus circumventing problems arising in canonical difference-in-differences approaches. The open-source flexpaneldid toolbox for Stata implements the developed approach and allows comprehensive robustness checks and quality tests. The core of the paper gives comprehensive examples to explain the use of the commands and its options on the basis of a publicly accessible data set.

Does Working at a Start-Up Pay Off?
Daniel Fackler, Lisa Hölscher, Claus Schnabel, Antje Weyh
Abstract
Using representative linked employer-employee data for Germany, this paper analyzes short- and long-run differences in labor market performance of workers joining startups instead of incumbent firms. Applying entropy balancing and following individuals over ten years, we find huge and long-lasting drawbacks from entering a start-up in terms of wages, yearly income, and (un)employment. These disadvantages hold for all groups of workers and types of start-ups analyzed. Although our analysis of different subsequent career paths highlights important heterogeneities, it does not reveal any strategy through which workers joining start-ups can catch up with the income of similar workers entering incumbent firms.

Intangible Capital and Productivity. Firm-level Evidence from German Manufacturing
Wolfhard Kaus, Viktor Slavtchev, Markus Zimmermann
IWH Discussion Papers,
No. 1,
2020
Abstract
We study the importance of intangible capital (R&D, software, patents) for the measurement of productivity using firm-level panel data from German manufacturing. We first document a number of facts on the evolution of intangible investment over time, and its distribution across firms. Aggregate intangible investment increased over time. However, the distribution of intangible investment, even more so than that of physical investment, is heavily right-skewed, with many firms investing nothing or little, and a few firms having very large intensities. Intangible investment is also lumpy. Firms that invest more intensively in intangibles (per capita or as sales share) also tend to be more productive. In a second step, we estimate production functions with and without intangible capital using recent control function approaches to account for the simultaneity of input choice and unobserved productivity shocks. We find a positive output elasticity for research and development (R&D) and, to a lesser extent, software and patent investment. Moreover, the production function estimates show substantial heterogeneity in the output elasticities across industries and firms. While intangible capital has small effects for firms with low intangible intensity, there are strong positive effects for high-intensity firms. Finally, including intangibles in a gross output production function reduces productivity dispersion (measured by the 90-10 decile range) on average by 3%, in some industries as much as nearly 9%.

Trade, Misallocation, and Capital Market Integration
Laszlo Tetenyi
IWH-CompNet Discussion Papers,
No. 8,
2019
Abstract
I study how cross-country capital market integration affects the gains from trade in a model with financial frictions and heterogeneous, forward-looking firms. The model predicts that misallocation among exporters increases as trade barriers fall, even as misallocation decreases in the aggregate. The reason is that financially constrained productive exporters increase their production only marginally, while unproductive exporters survive for longer and increase their size. Allowing capital inflows magnifies misallocation, because unproductive firms expand even more, leading to a decline in aggregate productivity. Nevertheless, under integrated capital markets, access to cheaper capital dominates the adverse effect on productivity, leading to higher output, consumption and welfare than under closed capital markets. Applied to the period of European integration between 1992 and 2008, I find that underdeveloped sectors experiencing higher export exposure had more misallocation of capital and a higher share of unproductive firms, thus the data is consistent with the model’s predictions. A key implication of the model is that TFP is a poor proxy for consumption growth after trade liberalisation.

Fiscal Stimulus and Consumer Debt
Yuliya Demyanyk, Elena Loutskina, Daniel Murphy
Review of Economics and Statistics,
No. 4,
2019
Abstract
In the aftermath of the consumer debt–induced recession, policymakers have questioned whether fiscal stimulus is effective during periods of high consumer indebtedness. This study empirically investigates this question. Using detailed data on Department of Defense spending for the 2007–2009 period, we document that the open-economy relative fiscal multiplier is higher in geographies with higher consumer debt. The results suggest that in the short term (2007–2009), fiscal policy can mitigate the adverse effect of consumer (over)leverage on real economic output during a recession. We then exploit detailed microdata to show that both heterogeneous marginal propensities to consume and slack-driven economic mechanisms contribute to the debt-dependent multiplier.

Fehlende Fachkräfte in Deutschland – Unterschiede in den Betrieben und mögliche Erklärungsfaktoren: Ergebnisse aus dem IAB-Betriebspanel 2018

IAB-Forschungsbericht 10/2019,
2019
Abstract
Seit der Überwindung der Wirtschaftskrise hat sich die wirtschaftliche Lage der Betriebe in West- und Ostdeutschland gleichermaßen verbessert. Gleichzeitig ist weiterhin ein positiver Beschäftigungstrend zu beobachten, der sich jedoch gegenüber dem Vorjahr etwas abgeschwächt hat. Der Fachkräftebedarf erreichte mit 2,7 Millionen Personen im Jahr 2018 einen neuen Höchststand. Nur noch etwa 60 Prozent des Bedarfs konnte gedeckt werden, was sich auch in einem erneuten Anstieg der Nichtbesetzungsquote äußert. Hinsichtlich der Verteilung dieses Indikators für Fachkräfteengpässe zeigen sich deutliche branchen- und größenspezifische Unterschiede in den Betrieben wie auch regionale Heterogenität. Mit mehr als der Hälfte unbesetzter Stellen ist im Baugewerbe und in der Land- und Forstwirtschaft der Fachkräfteengpass besonders akut. In einer multivariaten Analyse wird festgestellt, dass ein positiver Zusammenhang zwischen Fachkräfteengpässen und dem Einsatz von Leiharbeit, Arbeitszeitflexibilisierung sowie der Aus- oder Weiterbildungsbeteiligung eines Betriebes besteht. Die Tätigkeitsstruktur der Betriebe hat sich hinsichtlich formaler Qualifikationsanforderungen an die Beschäftigten in den vergangenen Jahren kaum verändert. Dagegen lässt sich ein deutlicher Trend zur Flexibilisierung der Arbeitsorganisation beobachten. So bieten etwa ein Viertel der Betriebe ihren Beschäftigten die Möglichkeit mobilen Arbeitens. Auch der Anteil der Teilzeitbeschäftigung nimmt bundesweit zu, insbesondere in Sektoren mit höherem Frauenanteil. Der Anteil geringfügiger Beschäftigung ist besonders hoch in Branchen, die eher unspezifische Qualifikationen erfordern oder stärker durch konjunkturelle und/oder saisonale Schwankungen gekennzeichnet sind – und in denen überdurchschnittliche Fachkräfteengpässe zu verzeichnen sind. Der Anteil ausbildungsberechtigter Betriebe ist im Jahr 2018 erstmals seit 2010 wieder gestiegen – in Gesamtdeutschland auf 54 Prozent. In Ostdeutschland liegt der Anteil mit 49 Prozent deutlich darunter. Unter den berechtigten Betrieben liegt die Ausbildungsbeteiligung seit mehreren Jahren relativ stabil bei etwa der Hälfte. Sowohl erfolgreich besetzte Ausbildungsplätze wie auch unbesetzte Ausbildungsstellen verteilen sich sehr heterogen auf die verschiedenen Branchen. Die Übernahmequote erfolgreicher Ausbildungsabsolventen liegt bei knapp drei Viertel. In Betrieben mit Fachkräfteengpass ist sowohl die Ausbildungsbeteiligung als auch die Übernahmequote höher, was darauf schließen lässt, dass hier die Berufsausbildung schon verstärkt zur Fachkräfterekrutierung eingesetzt wird. Hinsichtlich der Weiterbildungsbeteiligung lässt sich feststellen, dass unverändert etwa die Hälfte aller Betriebe sich an der Weiterbildung ihrer Beschäftigten beteiligt. Die Weiterbildungsquote der Beschäftigten liegt bei etwa einem Drittel, in Ostdeutschland etwas höher. Die vergleichsweise höhere Weiterbildungsquote von Beschäftigten auf Einfacharbeitsplätzen in Betrieben mit Fachkräfteengpass deutet darauf hin, dass hier gezielt interne Ressourcen zur Deckung des Fachkräftebedarfs genutzt werden.

HIP, RIP, and the Robustness of Empirical Earnings Processes
Florian Hoffmann
Quantitative Economics,
No. 3,
2019
Abstract
The dispersion of individual returns to experience, often referred to as heterogeneity of income profiles (HIP), is a key parameter in empirical human capital models, in studies of life‐cycle income inequality, and in heterogeneous agent models of life‐cycle labor market dynamics. It is commonly estimated from age variation in the covariance structure of earnings. In this study, I show that this approach is invalid and tends to deliver estimates of HIP that are biased upward. The reason is that any age variation in covariance structures can be rationalized by age‐dependent heteroscedasticity in the distribution of earnings shocks. Once one models such age effects flexibly the remaining identifying variation for HIP is the shape of the tails of lag profiles. Credible estimation of HIP thus imposes strong demands on the data since one requires many earnings observations per individual and a low rate of sample attrition. To investigate empirically whether the bias in estimates of HIP from omitting age effects is quantitatively important, I thus rely on administrative data from Germany on quarterly earnings that follow workers from labor market entry until 27 years into their career. To strengthen external validity, I focus my analysis on an education group that displays a covariance structure with qualitatively similar properties like its North American counterpart. I find that a HIP model with age effects in transitory, persistent and permanent shocks fits the covariance structure almost perfectly and delivers small and insignificant estimates for the HIP component. In sharp contrast, once I estimate a standard HIP model without age‐effects the estimated slope heterogeneity increases by a factor of thirteen and becomes highly significant, with a dramatic deterioration of model fit. I reach the same conclusions from estimating the two models on a different covariance structure and from conducting a Monte Carlo analysis, suggesting that my quantitative results are not an artifact of one particular sample.

Banks' Funding Stress, Lending Supply and Consumption Expenditure
H. Evren Damar, Reint E. Gropp, Adi Mordel
Abstract
We employ a unique identification strategy linking survey data on household consumption expenditure to bank-level data to estimate the effects of bank funding stress on consumer credit and consumption expenditures. We show that households whose banks were more exposed to funding shocks report lower levels of nonmortgage liabilities. This, however, only translates into lower levels of consumption for low income households. Hence, adverse credit supply shocks are associated with significant heterogeneous effects.
