We estimate turnover costs in small retail sales teams using daily sales data and an advance notice requirement to address endogeneity concerns. In addition to short-staffing and onboarding costs, we identify two less familiar sources of turnover costs: incumbent workers’ recruitment activities and reductions in team morale after a departure is announced. Our estimates of total turnover costs are relatively modest, however: 10% higher turnover is about as costly as a 0.6% wage increase. We attribute these low costs to a set of complementary personnel policies that ensure that only 25% of departures result in a short-staffing spell.

This paper utilizes wealth shocks from winning lottery prizes to examine the causal effect of financial resources on fertility. We employ extensive panels of administrative data encompassing over 0.4 million lottery winners in Taiwan and implement a triple-differences design. Our analyses reveal that a substantial lottery win can significantly increase fertility, the implied wealth elasticity of which is around 0.06. Moreover, the primary channel through which fertility increases is by prompting first births among previously childless individuals. Finally, our analysis reveals that approximately 25% of the total fertility effect stems from increased marriage rates following a lottery win.
