|October 2014||Housing Collateral, Credit Constraints and Entrepreneurship - Evidence from a Mortgage Reform|
with Thais Lærkholm Jensen, Ramana Nanda: w20583
We study how a mortgage reform that exogenously increased access to credit had an impact on entrepreneurship, using individual-level micro data from Denmark. The reform allows us to disentangle the role of credit access from wealth effects that typically confound analyses of the collateral channel. We find that a $30,000 increase in credit availability led to a 12 basis point increase in entrepreneurship, equivalent to a 4% increase in the number of entrepreneurs. New entrants were more likely to start businesses in sectors where they had no prior experience, and were more likely to fail than those who did not benefit from the reform. Our results provide evidence that credit constraints do affect entrepreneurship, but that the overall magnitudes are small. Moreover, the marginal individual...
|February 2014||Measuring the Accuracy of Survey Responses Using Administrative Register Data: Evidence from Denmark|
with Claus Thustrup Kreiner, David Dreyer Lassen
in Improving the Measurement of Consumer Expenditures, Christopher D. Carroll, Thomas F. Crossley, and John Sabelhaus, editors
We show how Danish administrative register data can be combined with survey data at the individual level and used to validate information collected in the survey. Two examples illustrate the potential of combining survey and register data. First, expenditure survey records with information about total expenditure are merged with income tax records with information about income and wealth, which is used to impute total expenditure, then compared to the survey measure. Results suggest the two measures match each other well on average. Second, we compare responses to a one‐shot recall question about total gross personal income collected in another survey with tax records. Tax records hold detailed information about different types of income, which makes it possible to test whether response e...
|October 2013||Measuring the Accuracy of Survey Responses using Administrative Register Data: Evidence from Denmark|
with Claus Thustrup Kreiner, David Dreyer Lassen: w19539
This paper shows how Danish administrative register data can be combined with survey data at the person level and be used to validate information collected in the survey. Register data are collected by automatic third party reporting and the potential errors associated with the two data sources are therefore plausibly orthogonal. Two examples are given to illustrate the potential of combining survey and register data. In the first example expenditure survey records with information about total expenditure are merged with income tax records holding information about income and wealth. Income and wealth data are used to impute total expenditure which is then compared to the survey measure. Results suggest that the two measures match each other well on average. In the second example we compar...
|November 2012||Active vs. Passive Decisions and Crowdout in Retirement Savings Accounts: Evidence from Denmark|
with Raj Chetty, John N. Friedman, Torben Nielsen, Tore Olsen: w18565
Using 41 million observations on savings for the population of Denmark, we show that the impacts of retirement savings policies on wealth accumulation depend on whether they change savings rates by active or passive choice. Subsidies for retirement accounts, which rely upon individuals to take an action to raise savings, primarily induce individuals to shift assets from taxable accounts to retirement accounts. We estimate that each $1 of government expenditure on subsidies increases total saving by only 1 cent. In contrast, policies that raise retirement contributions if individuals take no action - such as automatic employer contributions to retirement accounts - increase wealth accumulation substantially. We estimate that approximately 15% of individuals are "active savers" who respond t...
