In a Bewley model with endogenous price volatility, home ownership and mobility across locations and jobs, we assess the contribution of financial constraints, housing illiquidities and house price risk to home ownership over the life cycle. The model can explain the rise in home ownership and fall in mobility over the life cycle. While some households rent(More)
Quinolinic acid (QA) content was measured in postmortem frontal and temporal cortex, putamen and cerebellum obtained from patients with senile dementia of Alzheimer type (SDAT), Huntington's disease (HD) and controls, using a gas chromatography/mass spectrometry method. There were no significant group differences in QA content of any of the regions(More)
Urinary output of endogenous monoamine oxidase (MAO) inhibitory activity, was significantly raised in serial samples collected across a migraine attack compared with collections during attack-free periods and in healthy controls, which did not differ from each other. There was a highly significant correlation in output between isatin, a major fraction of(More)
Homogentisic acid (HGA) (50 mg/kg) was given orally to 22 obligate heterozygotes for hereditary tyrosinemia type 1 (HT) and to 11 controls. After 1 h the mean +/- standard error (SE) plasma level of HGA was 30.42 +/- 1.41 micrograms/ml in carriers and 19.29 +/- 1.62 in controls. Mean +/- SE fasting delta-amino-levulinate dehydratase (delta-ALD) was 40.05(More)
The analytical application of direct pyrolysis (Py) field ionization (FI)-mass spectrometry (MS) und Curie-point pyrolysis gas chromatography-mass spectrometry (Py-GC/FIMS) to various whole foodstuffs is described for the first time. The former technique yields highly differentiated information from the sample in typically 15 min, namely the molecular(More)
Are households more likely to be homeowners when “housing risk” is higher? We show that homeownership rates and loan-to-value (LTV) ratios at the city level are strongly negatively correlated with local house price volatility. However, causal inference is confounded by house price levels, which are systematically correlated with housing risk in an intuitive(More)
In this paper, I use a Markov Chain Monte Carlo algorithm to estimate a macroeconomic model of private-sector behavior that does not feature private-sector knowledge of the monetary policymaking process and, instead, leaves firms and households uncertain about how monetary policy is set. In particular, the private sector is endowed with two competing views(More)
We develop a new dynamic equilibrium model of housing markets for lowand moderate-income households, which is consistent with the key supply restrictions and search frictions that arise in rental markets for public and affordable housing. We estimate the model using data collected by the New York Housing Vacancy Survey in 2011. We find that having access to(More)
Here, we check for robustness in the impact of price levels and volatilities on ownership (Table S.1) and LTV (Table S.2). We report results for both OLS and instrumental variables (IV) (with land scarcity as the instrument) for volatilities measured using different windows (5 years, as in the main text, and 10 years also), for different year cross sections(More)
