Working Paper: Monetary and Fiscal Policies in Times of Large Debt Unity is Strength

We study the implications of a coordinated fiscal and monetary strategy aiming at creating a controlled rise of inflation to wear away a targeted fraction of debt. Under this strategy, the fiscal authority introduces an emergency budget with no provisions on how it will be balanced, while the monetary authority tolerates a temporary increase in inflation to accommodate the emergency budget.


Working Paper: The Macroeconomic Effects of Shadow Banking Panics

We study the effects of shadow banking panics in a macroeconomic model with a rich financial system, including deposit-financed retail banks and wholesale-financed shadow banks. The model can quantitatively match the dynamics of key variables around the US financial crisis. Wholesale funding market interventions akin to those implemented by the Federal Reserve in 2008 reduced the fall in output by about half a percentage point. Generally, central bank interventions reduce output volatility and the likelihood of banking panics.


Working Paper: Dispersed consumption versus compressed output: assessing the sectoral effects of a pandemic

I process credit-card consumption data through an input-output model of sectoral linkages to impute the sector-level output responses to the Covid-19 pandemic. The sector-level consumption responses are highly dispersed and even positive for some. Yet, all sectors suffer from output losses. Production of intermediate goods stabilizes output. Consequently, the sectoral dispersion of final consumption is larger than sectoral dispersion of output produced.


Working Paper: Mandatory pension savings and long-run debt accumulation: Evidence from Danish register data

This paper uses two decades of individual level information from Danish administrative registers to investigate the connection between pension wealth and debt accumulation. A 1-dollar increase in pension wealth leads to a 26-cent rise in total debt. Liquidity constraints seem to play a key role, and we couple the crowding-out effect with an increased propensity to use interest-only mortgages.


Working Paper: Bad Jobs and Low Inflation

The low rate of inflation observed in the U.S. over the entire past decade is hard to reconcile with traditional measures of labor market slack. We show that an alternative notion of slack that encompasses workers' propensity to search on the job explains this missing inflation.


Working Paper: Modest pass-through of monetary policy to retail rates but no reversal

Monetary policy rates are negative in a number of countries, including Denmark. Concern has been expressed that negative rates may, in some cases, have had undesirable effects on bank lending rates. We show that in Denmark, pass-through to bank lending rates remains positive, and we do not find indications to suggest that negative rates have weakened bank lending. The pass-through of monetary policy interest rates to bank lending rates slowed around the financial crisis, and we show that this is driven primarily by the banks with the highest risk exposure before the crisis.


Working Paper: Macro-financial interactions in a changing world

We measure the time-varying strength of macro-financial linkages within and across the US and euro area economies. The main results show that the euro area is disproportionately more sensitive to shocks in the US macroeconomy and financial sector. Moreover, while macro-financial interactions have steadily increased in the euro area since the late 1980s, they have oscillated in the US, exhibiting very long cycles of macro-financial interdependence.


Working paper: The impact of inflation targeting: Testing the good luck hypothesis

Was the fall in the level and volatility of inflation over the last 30 years the result of good luck, or good monetary policy? We assess the inflation experience of Canada, an early adopter of an inflation targeting policy. Good luck explains only a minor portion of the changes in inflation after the shift in policy. Most of inflation and output stabilization is explained by the impact on expectations.


Working paper: Modeling frailty correlated defaults with multivariate latent factors

It is typically assumed within corporate default modeling that the covariates have a linear effect on the log-hazard scale, no interactions, and that there is only a single additive latent factor on the log-hazard scale. Using a sample of US corporate firms, we show in this paper that these standard assumptions are too strict and that they matter in practice. We propose instead a frailty-model that relaxes these assumptions and takes into account time-varying covariates, while being able to provide forecasts for arbitrary portfolios.


Working paper: Mortgage choice and expenditure over the lifecycle: evidence from expiring interest-only loans

We study how homeowners’ consumption responds to the beginning of the amortization period on interest-only mortgages. In response to an average increase in mortgage instalments worth 9 per cent of annual income, consumption drops by 3 percent of income, in the year when amortization starts. This expenditure cut is persistent, but only affects a small subset of borrowers with high leverage ratios. These borrowers might have been unable to rollover their interest-only loans into new ones.


Working paper: Banking panic risk and macroeconomic uncertainty

We show that systemic risk in the banking sector breeds macroeconomic uncertainty. We develop a model of a production economy with a banking sector where financial constraints of banks can lead to disastrous banking panics. We find that a higher probability of a banking panic increases uncertainty in the aggregate economy. We explore the implications of this banking panic-driven uncertainty for business cycles, asset prices and macroprudential regulation. Banking panic-driven uncertainty amplifies business cycle volatility and increases risk premia on asset prices. A countercyclical capital buffer lowers both the probability of banking panics and aggregate uncertainty.


Working paper: What is real and what is not in the global FDI network?

Macro statistics on foreign direct investment (FDI) are blurred by offshore centers with enormous inward and outward investment positions. This paper uses several new data sources to estimate the global FDI network while disentangling real investment and phantom investment and allocating real investment to ultimate investor economies. We find that phantom investment into corporate shells with no substance and no real links to the local economy may account for almost 40 percent of global FDI.


Working paper: Occupation-industry mismatch in the cross-section and the aggregate

I define occupations that are employed in more industries as “broader” occupations. I study the implications of broadness for mismatch of the unemployed and vacancies across occupations and industries. I empirically find that workers in broader occupations are better insured against industry-specific shocks. I build a general equilibrium model that uses occupational broadness as a microfoundation of mismatch. The model matches the empirical findings but predicts that mismatch cannot significantly contribute to aggregate fluctuations in the unemployment rate.


Working paper: Liquidity Constraints in the U.S. Housing Market

We show that U.S. housing wealth is very illiquid despite all the instruments for extracting home equity available to homeowners. We come to this conclusion by studying the implications of liquidity constraints in a quantitative life-cycle model in which we explicitly account for key institutional details of the U.S. housing and mortgage markets. We find that mortgage market frictions that prevent homeowners from tapping into home equity are sizeable and that most homeowners keep their consumption low for precautionary reasons.


Working Paper: Risk and risk weights

The paper studies the relationship between the riskiness of banks' assets and their average risk weight. Risk weights explain about half of the variation in projected credit losses in the 2018 European Banking Authority stress test, and show a clear relationship with estimates of banks' asset volatilities. However, risk weights do a worse job of explaining future credit losses than do asset volatilities, especially for banks using internal models.


Working Paper: Revisiting the inflation perception conundrum

The level of inflation perceived by Danish households persistently exceed observed inflation levels measured by official Consumer Price Indices. Accounting for even several of the factors usually put forward to explain the overestimation bias can only reduce it slightly. Food prices carry a larger weight in perceived inflation than in the official CPI, and we find clear seasonal effects in the inflation perception bias. The bias is also reflected in the households' expectations of the future inflation level, but we find a much smaller bias in the expectations regarding future changes in inflation rates.


Working Paper: Ahead of the Cycle

The paper describes how to conduct macroprudential policy in an environment where economic indicators move in a cyclical fashion, policy works with a lag, and there are adjustment costs to changing policy. It shows that policy instruments such as the countercyclical capital buffer should be set not only based on the present state of the cycle, but also on where the cycle is heading.


Working Paper: Modeling Persistent Interest Rates with Volatility-Induced Stationarity

We propose a new model for the term structure of interest rates, which embraces the extreme persistence observed in interest rate data. This is achieved by introducing so-called volatility-induced stationarity. We apply the model to U.S. Treasury bond yield data and show that volatility-induced stationarity improves estimation of term premia and forecasting of interest rates compared to existing models.


Working Paper: Seeing Through the Spin: The Effect of News Sentiment on Firms' Stock Market Performance

We show that Stock market investors react only on the objective facts and not the spin in media articles. We use natural language processing tools to compute the tone of 288 thousands articles written by Reuters between 2000 and 2018, and show that it predicts the short-term stock market performance of companies. However, by exploiting a combination of unsupervised machine learning and econometric techniques, we show that this effect is only due to the informational content of the article, and not the framing of that article. The market sees through media spin and can filter informational content from irrelevant tone.


Working Paper: Macroeconomic and financial policies for climate change mitigation: A review of the literature

Climate change is one of the greatest challenges of this century. Mitigation requires a large-scale transition to a low-carbon economy. This paper provides an overview of the rapidly growing literature on the role of macroeconomic and financial policy tools in enabling this transition.
