Is there a flight to quality due to inflation uncertainty?
After two types of inflation uncertainty are derived within a time-varying parameter model with GARCH specification, the relationship between inflation uncertainty and interest rates for safe assets is investigated. The results support the existence of a ‘‘flight to quality’’ effect.
Joint-search theory: new opportunities and new frictions
Search theory routinely assumes that decisions about the acceptance/rejection of job offers (and, hence, about labor market movements between jobs or across employment states) are made by individuals acting in isolation. In reality, the vast majority of workers are somewhat tied to their partners - in couples and families - and decisions are made jointly. This paper studies, from a theoretical viewpoint, the joint job-search and location problem of a household formed by a couple (e.g., husband and wife) who perfectly pools income. The objective of the exercise, very much in the spirit of standard search theory, is to characterize the reservation wage behavior of the couple and compare it to the single-agent search model in order to understand the ramifications of partnerships for individual labor market outcomes and wage dynamics. We focus on two main cases. First, when couples are risk averse and pool income, joint search yields new opportunities - similar to on-the-job search - relative to the single-agent search. Second, when the two spouses in a couple face job offers from multiple locations and a cost of living apart, joint search features new frictions and can lead to significantly worse outcomes than single-agent search.Search theory ; Unemployment ; Wages

Search theory routinely assumes that decisions about the acceptance/rejection of job offers (and, hence, about labor market movements between jobs or across employment states) are made by individuals acting in isolation.

Assessment of fetal adrenal gland enlargement in term and preterm labor cases
Background: The objective of this study was to compare the Fetal Zone Depth (FZD) of fetal adrenal gland in term and preterm labor cases.  Methods: Twenty nine preterm pregnant women at 29-36 weeks of gestation with single pregnancy admitted with the clinical diagnosis of preterm labor and the comparison group of 33 pregnant women at 37-40 weeks with term pregnancy were included in this study. FZD and Total Gland Depth (TGD) of fetal adrenal gland of the entire fetuses in sagittal plane were ultrasonographically measured and FZD/TGD ratios were calculated. Demographic and clinical features, laboratory findings and fetal adrenal gland FZD/TGD ratios were compared between the two groups.Results: No difference was found between the two groups in respect of age, number of pregnancies and delivery method (P >0.05); yet preterm birth history and duration of hospital stay were higher in preterm group (P <0.05). Fetal adrenal gland FZD/TGD ratio was statistically significantly higher in preterm group compared to the term group (55.4% ± 4.9 vs. 47.7% ± 5.6; P <0.001).Conclusion: The growth in FZ as a fetal adaptation mechanism in increased fetal stress in preterm labor cases was at a significant level. Once supported by more comprehensive studies, we think that this result would be beneficial in the prediction of preterm labor in clinical practice.
Joint Dynamics of House Prices and Foreclosures *
Abstract This paper studies the joint transitional dynamics of the foreclosures and house prices in a standard life-cycle incomplete markets model with housing and a realistic long-term mortgage structure. We calibrate our model to match several long term features of the US housing market, and analyze the effects of several unexpected and permanent shocks on the house price and the foreclosure rate both across the steady-states and along the transition between the steady-states. we examine permanent, unexpected shocks to the risk-free interest rate, the minimum down payment ratio, and unemployment. During the transition, these shocks create large movements in house prices. More importantly, the foreclosure dynamics are quite significant along the transition compared to the steadystate changes, and there are strong feedbacks between foreclosures and house prices. We assess the effects of a temporary reduction in the risk-free interest rate, which has moderate effects on house prices but little effect on foreclosure dynamics. We also study the effects of an ex-ante macroprudential policy, which establishes a minimum downpayment requirement at a higher threshold. Such a macroprudential policy helps substantially stabilize both house prices and foreclosures
