摘要：
we propose a new method for identifying bargaining power in collective household models, based on information asymmetry. our model allows household members to exploit an information advantage for bargaining. we formulate the household's decision process under partial information disclosure using a bayesian persuasion framework. we use this structure to point identify utility and bargaining power, which would not be identified under symmetric information. we illustrate these results by showing that our model can explain known empirical outcomes regarding child educational investment and development in chinese households where one parent is a migrant.

摘要：
this paper assesses the debate about the demise of the chinese silver standard in the mid 1930s. one side argues the u.s. silver purchase act of june 1934 drained china of silver, which caused deflation and economic crises. a related claim is the chinese silver standard was intrinsically unstable. these hypotheses are evaluated by estimating bayesian structural vars with drifting parameters on china-u.k. and china-u.s. samples from april 1912 to september 1934. we find instability in the chinese silver standard peaked during the nber recession of january 1920–july 1921 and the great depression (august 1929–march 1933). hence, neither the u.s. silver purchase act of june 1934 nor a design flaw lead to the end of the chinese silver standard.

摘要：
this paper models the joint dynamics of macro aggregates and functional variables within the structural var framework. i reduce the dimension of the system using functional pca and show that the proposed functional var (fvar) consistently recovers the responses of the functions. the fvar is easy to implement and fully compatible with conventional svar tools. simulation evidence shows that it performs satisfactorily in finite samples. applying fvar to study the impact of tax shocks on income distributions in the uk, i find that tax cuts persistently reduce the density of lower-middle-class households, which is offset by a substantial increase in the richer range and a moderate increase in the poorer range. however, this pattern is not captured by vars with conventional inequality measures.
