Intrinsic Parameters of GRB990123 from Its Prompt Optical Flash and Afterglow [PDF]
, 1999 We have constrained the intrinsic parameters, such as the magnetic energy density fraction ($\epsilon_{B}$), the electron energy density fraction ($\epsilon_e$), the initial Lorentz factor ($\Gamma_0$) and the Lorentz factor of the reverse external shock

Financial Factors in Economic Fluctuations
Social Science Research Network, 2010 We augment a standard monetary DSGE model to include a banking sector and financial markets. We fit the model to Euro Area and US data. We find that agency problems in financial contracts, liquidity constraints facing banks and shocks that alter the ...

Physical parameters of GRB 970508 and GRB 971214 from their afterglow synchrotron emission [PDF]
, 1998 We have calculated synchrotron spectra of relativistic blast waves, and find predicted characteristic frequencies that are more than an order of magnitude different from previous calculations.

Modeling GRB 050904: Autopsy of a Massive Stellar Explosion at z=6.29 [PDF]
, 2006 GRB 050904 at redshift z=6.29, discovered and observed by Swift and with spectroscopic redshift from the Subaru telescope, is the first gamma-ray burst to be identified from beyond the epoch of reionization. Since the progenitors of long gamma-ray bursts

From blast wave to observation [PDF]
, 2009 Gamma-ray burst (GRB) afterglows are well described by synchrotron emission originating from the interaction between a relativistic blast wave and the external medium surrounding the GRB progenitor.

How Do Firms Form Their Expectations? New Survey Evidence
The American Economic Review, 2015 We survey New Zealand firms and document novel facts about their macroeconomic beliefs. There is widespread dispersion in beliefs about past and future macroeconomic conditions, especially inflation.

The Nexus of Monetary Policy and Shadow Banking in China
The American Economic Review, 2017 We study how monetary policy in China influences banks’ shadow banking activities. We develop and estimate the endogenously switching monetary policy rule that is based on institutional facts and at the same time tractable in the spirit of Taylor (1993).

A Model of Secular Stagnation: Theory and Quantitative Evaluation
American Economic Journal: Macroeconomics, 2017 This paper formalizes and quantifies the secular stagnation hypothesis, defined as a persistently low or negative natural rate of interest leading to a chronically binding zero lower bound (ZLB).
