Do oil endowment and productivity matter for accumulation of international reserves?
We develop a dynamic stochastic optimization model with oil price shocks to show that countries with certain combinations of oil endowment and productivity have strong precautionary incentives to accumulate foreign reserves in response to oil price shocks. Using the Simulated Method of Moments to estimate the model we demonstrate how oil price shocks are absorbed by changes in foreign reserves which, in turn, leads to less variation in aggregate consumption. Along with productivity and oil endowment, we also consider as determinants of reserves holding conventional variables such as trade- ...

Home production technology and time allocation: empirics, theory, and implications
We document a set of time use patterns in both time series and cross sections. To explain these facts, we propose and estimate a model of time allocation that emphasizes the role of home production technology. We find it necessary to consider both labor-augmenting technology and total factor productivity in home production. Based on the estimated model, we study the effects of proportional tax and lump-sum transfer on time allocation and labor supply, with the roles of home production technology and wage heterogeneity highlighted.

Personal Bankruptcy as a Real Option
We provide a novel explanation to the longstanding puzzle of the ?missing bankruptcy ?lings.? Even though a household with a negative net worth will receive contemporaneous bene?t from bankruptcy, there may be greater insurance value from delaying the ?ling. Household bankruptcy is thus an American-style put option, which is not necessarily exercised even if the option is "in the money." Based on the value functions in the household?s dynamic programming problem, we formulate the value of the bankruptcy option as well as the exercise price. We estimate a life-cycle model in which households ...

Is the Renminbi a safe haven?
We investigate the relationship between market uncertainty and the relative value of the Renminbi against currencies that the safe haven literature typically considers as the traditional safe haven currency candidates. Our sample spans the February 2011 to April 2016 period. Band spectral regression models enable us to capture that the relationship between market uncertainty and the relative value of the Renminbi is frequency dependent. While we find evidence of some degree of safe haven currency behavior of the Renminbi during the early part of our sample, our findings do not support the ...
