This paper investigates the effect of co-worker characteristics on wages, measured by the average person effect of coworkers in a wage regression. The effect of interest is identified from within-firm changes in workforce composition, controlling for personeffects, firm effects, and...

Using data from a survey of German manufacturing firms, this paper empirically tests the hypothesis that investment in ICT enables product innovation at the firm level. The empirical approach employs a value-added model, which controls for time-invariant firm characteristics. We instrument with...

This paper advocates for incorporating timely measures of firms' current situation and future expectations when disentangling real effects of credit supply from demand-side factors. Identification of supply-side effects in firm-level analyses often relies on balance sheet variables to control...

Solid budgets serve as important quality signals for the electorate. Politicians mighttherefore face an incentive to influence tax revenue forecasts, which are widely regardedas a key element for budget setups. Looking at the time period from 1996 to 2012, inthis study we systematically analyze...

We analyze monopoly power in a market for a complementary fossil resource like oil in a twocountry/two period model with international trade in general equilibrium. Focusing on thecomplex interplay of capital and resource market, we elaborate how these effects feed backinto the resource...

In this study, we evaluate whether survey-based indicators produce lower forecast errorsfor export growth than indicators obtained from hard data such as price and costcompetitiveness measures. Our pseudo out-of-sample analyses and forecastencompassingtests reveal that survey-based indicators...

The development of climate-friendly technologies and its diffusion across countries is of key importance to slow climate change. This paper considers technologies in the mobile air-conditioning (MAC) sector which is a major contributor of fluorinatedgreenhouse gas emissions. Using patents as an...

We examine the impact of lay-off risks on wages. Portfolio as well as search theoreticmodelling predicts higher exogenous lay-off risks to go along with higher wages. But,an impact of wages on lay-off risks (e.g., endogenous job destruction) is also plausible.Using the German BA Employment Panel...

The Kyoto Protocol’s success or failure should be evaluated against the unobserved counterfactual of no treatment. This requires instrumental variables. We find that countries’ membership in the International Criminal Court (ICC) predicts Kyoto ratification in a panel model. Both...

A country’s carbon footprint refers to the CO₂ emissions caused by domestic absorptionactivities. Trade in goods drives a wedge between the footprint and local emissions. Weprovide a panel database on carbon footprints and carbon net trade. Using a differencesin-differences IV estimation...
