Financial Intermediaries, Markets, and Growth

We build a model in which financial intermediaries provide insurance to households against idiosyncratic liquidity shocks. Households can invest in financial markets directly if they pay a cost. In equilibrium, the ability of intermediaries to share risk is constrained by the market. From a growth perspective, this can be beneficial because intermediaries invest less in the productive technology when they provide more risk-sharing. Our model predicts that bank-oriented economies can grow more slowly than more market-oriented economies, which is consistent with some recent empirical evidence.     

Is Proprietary Trading Detrimental to Retail Investors?

We study the conflict of interest that arises when a universal bank conducts proprietary trading alongside its retail banking services. Our data set contains the stock holdings of every German bank and those of their corresponding retail clients. We investigate (i) whether banks sell stocks from their proprietary portfolios to their retail customers, (ii) whether those stocks subsequently underperform, and (iii) whether retail customers of banks engaging in proprietary trading earn lower portfolio returns than their peers. We present affirmative evidence for all three questions and conclude that proprietary trading can, in fact, be detrimental to retail investors.     

Variations in Market Liquidity and the Intraday Interest Rate

Most central banks offer banks participating in large‐value real‐time gross settlement (RTGS) systems a free intraday overdraft facility to discourage banks from actively managing their daylight liquidity. In this paper, we ask whether this facility has kept the intraday interest rate at zero. Using a unique transaction‐level data set on collateralized interbank loans for 2006–12, we find that during periods of financial distress, rates for morning transactions are higher than those in the afternoon. Moreover, this intraday rate correlates with market liquidity, suggesting that rates contain a liquidity premium. This intraday pattern is reduced, but not eliminated by the Eurosystem's accommodative liquidity provision.     

Fiscal Policy and Occupational Employment Dynamics

We document substantial heterogeneity in occupational employment dynamics in response to government spending shocks in the United States. Employment rises most strongly in service, sales, and office (“pink-collar”) occupations. By contrast, employment in blue-collar occupations is hardly affected by fiscal policy. We provide evidence that occupation-specific changes in labor demand are key for understanding these findings. We develop a business-cycle model that explains the heterogeneous occupational employment dynamics as a consequence of composition effects due to heterogeneous employment changes across industries and occupation-specific within-industry employment shifts due to differences in the short-run substitutability between labor and capital services across occupations.     

Bringing Back the Jobs Lost to Covid-19: The Role of Fiscal Policy

Covid-19 induced job losses occurred predominantly in industries with intensive worker–client interaction as well as in pink-collar and blue-collar occupations. We study the ability of fiscal policy to stabilize employment by occupation and industry during the Covid-19 crisis. We use a multisector, multioccupation macro-economic model and investigate different fiscal-policy instruments that help the economy recover faster. We show that fiscal stimuli foster job growth for hard-hit pink-collar workers, whereas stimulating blue-collar job creation is more challenging. Only a cut in labor income taxes generates a substantial number of blue-collar jobs.
