Pre-registration
Israel absorbed approximately 900,000 Soviet Jewish immigrants 1989-1994 (~20% of the pre-immigration population). The hypothesis tests whether the high-skill composition (engineers, scientists, doctors) of the inflow is associated with measurable productivity gains and tech-sector employment growth in Israel 1990-2010, supporting the canonical view that Israel's tech-cluster emergence was substantially Soviet-immigrant-enabled.
Falsification criterion — what would disprove this
This hypothesis is considered falsified if:
SUPPORTED if foreign-born share rises by at least 15pp 1989-1994 AND post-1994 TFP growth exceeds pre-1989 trend by at least 0.5pp annualised through 2005. REFUTED if foreign-born share rise < 10pp OR TFP gain insignificant against pre-trend.

event_study- Sample
- 1 countries · 1985 – 2010
- Evidence type
- descriptive
Event-study around 1989-1994 with Israel as the single treated unit; report break in foreign-born share, TFP, and per-capita output. Counterfactual based on linear extrapolation of 1985-1988 trend.

Pre-registration
- Claim: Israel absorbed approximately 900,000 Soviet Jewish immigrants 1989-1994 (~20% of the pre-immigration population). The hypothesis tests whether the high-skill composition (engineers, scientists, doctors) of the inflow is associated with measurable productivity gains and tech-sector employment growth in Israel 1990-2010, supporting the canonical view that Israel's tech-cluster emergence was substantially Soviet-immigrant-enabled.
- Falsification rule: SUPPORTED if foreign-born share rises by at least 15pp 1989-1994 AND post-1994 TFP growth exceeds pre-1989 trend by at least 0.5pp annualised through 2005. REFUTED if foreign-born share rise < 10pp OR TFP gain insignificant against pre-trend.

Strongest opposing argument
Every hypothesis ships with its charitable opposing argument. The framework earns credibility by handling objections at their strongest, not weakest.
