JEL Classification: J15, N31 Improving early prenatal and postnatal conditions account for at least 16 to 17 percent of the decline in ten year mortality rates of 60-79 year olds between 1900 and 1960-80. Historical trends in early prenatal and postnatal conditions imply that while the baby-boom cohort may be particularly long-lived compared to past cohorts, mortality rates may not fall as stee...

When countries change most favored nation (MFN) tariffs, partners that trade on MFN terms experience plausibly exogenous tariff changes. Using this variation, we estimate the elasticity at short and long horizons with local projections. We find of tariff-exclusive flows is ?0.76 in run, approximately ?2 run. Our long-run estimates are smaller than typical literature, it takes 7 to10 years to co...

The distributions of income and wealth in countries across the world are found to possess some robust and stable features independent of the specific economic, social and political conditions of the countries. We discuss a few physics-inspired multiagent dynamic models along with their microeconomic counterparts, that can produce the statistical features of the distributions observed in reality...

We show the robustness of the Walrasian result obtained in models of bargaining in pairwise meetings. Restricting trade to take place only in pairs, most of the assumptions made in the literature are dispensed with. These include assumptions on preferences (differentiability, monotonicity, strict concavity, bounded curvature), on the set of agents (dispersed characteristics) or on the consumpti...

After the Great Recession several central banks started setting negative nominal interest rates in an expansionary attempt, but effectiveness of this measure remains unclear. Negative can stimulate economy by lowering that commercial charge on loans, they also erode bank profitability squeezing deposit spreads. This paper studies effects a new DSGE model where intermediate transmission monetary...

We propose a model of banks’ exposure to movements in interest rates and their role the transmission monetary shocks. Since bank deposits provide liquidity, higher allow banks earn larger spreads on deposits. Therefore, if risk aversion is than one, optimal dynamic hedging strategy take losses when rise. This can be achieved by traditional maturity-mismatched balance sheet amplifies effects sho...

The responsiveness of house prices to monetary policy shocks depends on the nature shock—expansionary versus contractionary—and local housing supply elasticities. These findings are established using a panel 263 US metropolitan areas. Expansionary have larger impact in supply-inelastic Contractionary orthogonal In supply-elastic areas, contractionary greater than expansionary do. opposite holds...

this article is a comparative study of estimation power of artificial neural networks and autoregressive time series models in inflation forecasting. using 37 years iran’s inflation data, neural networks performs better on average for short horizons than autoregressive models. this study shows usefulness of early stopping technique in learning stage of neural networks for estimating time series...

The estimation of dynamic factor models for large sets of variables has attracted considerable attention recently, due to the increased availability of large datasets. In this paper we propose a new methodology for estimating factors from large datasets based on state space models, discuss its theoretical properties and compare its performance with that of two alternative estimation approaches ...
