The Economic History Review, EarlyView.
Abstract The paper discusses the novel but little‐known exchange rate system of Japanese‐occupied North China during the Second Sino‐Japanese War, in which exporters were given the right to import in the form of a piece of yellow paper, which could be sold in the secondary market.

Considerations for the Design of Sinusoidal Slug Testing Methods

Groundwater, EarlyView.
Periodic hydraulic tests estimate aquifer properties using controlled groundwater‐level oscillations. Evaluating two sinusoidal slug‐test designs shows large motion errors when transfer‐link and flywheel ratios are high or variable. Rotating‐drive mechanisms are therefore suboptimal; stepper‐motor winches generate more accurate sinusoidal motion ...

The Legacy of Policy Inaction in Climate‐Growth Models

International Economic Review, EarlyView.
ABSTRACT To better understand the structure and core mechanisms of a broad class of climate‐growth models, we study a simplified version of the dynamic integrated model of climate and the economy (DICE) through the lens of growth theory. We analytically show that this model features a continuum of saddle‐point stable steady states.

To Grandmother's House We Go: Informal Childcare and Female Labor Mobility

International Economic Review, EarlyView.
ABSTRACT We document how childcare costs and the location of extended family influence the labor supply and mobility of US women. Women return to their home locations immediately before fertility events, suggesting that informal childcare needs may motivate home migration. Women who live near their parents have lower child earnings penalties.
